I. The essential hypothesis of channel press
After the channel press is squeezed and held under tension, the slurry is compelled to go through the channel medium under the activity of strain, and the strong particles are caught on the medium while the fluid goes through the channel medium, consequently accomplishing the reason for isolating the fluid from the solids.
Two, the order of the channel press
(1) According to the sifting component: plate and edge type, chamber type, stomach type
(2) According to the fluid outlet: splendid stream, dim stream, brilliant and dull general
(3) According to the construction of the edge: pillar type, suspension type, outline type
(4) as indicated by the wellspring of strain: pressure driven (water powered self-safeguarding, manual locking, manual water powered), manual, mechanical
5）According to the level of mechanization: programmed, self-loader, manual
6）According to the washing strategy: smooth washing, turn around washing (single direction washing, two-way washing, two-way cross washing, side washing)
(7) According to the plate taking care of strategy: upper corner taking care of, upper center taking care of, center taking care of, lower corner taking care of
(8) According to the establishment bearing of the channel plate: level, vertical, drum type
Typically the normal is level channel press, and the normal in the flat is the side shaft type and high hanging bar type, of which the side bar type channel press is the fundamental result of the channel press producing industry, representing 95% of the result of the channel press industry, so all faculty occupied with the plan, handling, fabricating, establishment, dispatching and support of the channel press ought to have adequate information and comprehension.
Three, the organization of the channel press
The channel press is basically made out of edge, water driven framework, electric control framework, channel plate and assistant framework.
Four, the computation strategy for the strain power of the channel press
- The evaluated feed strain of the channel press F1 = water driven framework pressure P1 X pressure driven chamber bore region S1
- A piece of the channel chamber pushback pressure F2 = working tension P2 (filtration, washing, blowing, squeezing) X the compelling region inside the channel chamber S2
(1) The functioning tension inside the channel chamber is dependent upon the pressure strain of the channel press, for example the most extreme working tension permitted by the channel press outline, and so on
2) The greatest working strain took into consideration the channel plate at a specific working temperature.
(3) F1>F2 (the squeezing strain ought to be more prominent than the feed pressure).
V. Establishment of the channel press
(1) When introducing the channel press, first and foremost check the substantial establishment structure, which ought to be smooth and strong; when emptying the material, the passerby section ought to be smooth to work with the activity, and an entry of around 1m in width ought to be left around the channel press; the edge ought to be evened out and slantingly amended, the tail plate legs ought to be fixed with foot bolts, and the oil chamber legs ought not be fixed, and the contact surface with the ground ought to be smooth to guarantee that it keeps a specific free removal under the power.
(2) Check whether the bolts associating the channel press outline are fixed, regardless of whether the channel plates are conveniently organized and whether the openings are accurately situated, and introduce the fluid outlet spout at the lower end of the channel plate in the open-stream channel press and fix it; assuming that the client requires the utilization of a getting plate or a fold, the foundation of the entire machine ought to be a sure size higher than the establishment surface to leave space for the getting plate or fold.
(3) The channel plate ought to be flawlessly organized on the casing and no shifting is permitted to try not to influence the typical utilization of the channel press; the channel fabric should be kept level and can’t be collapsed, any other way there will be material spillage; the electrical discharges fabric clasping gadget should be fixed equitably to keep the channel material near the bay, any other way the channel slurry will enter between the channel material and the channel plate and influence the ordinary utilization of the channel press.
4) The area of the pressure driven station still up in the air as per the real site of the client (a few models have the siphon station and electric box introduced on the edge), with the briefest conceivable pipeline, the most limited distance being inside 1.5m; the water powered station ought to be far away from the dumping place, so the material won’t fall on top of the pressure driven station and influence the ordinary utilization of the pressure driven parts or engine; check whether the oil pipe associations are free and the oil tank is spotless, and afterward fill the oil tank with HM46 or HM68 against wear water powered oil. or then again HM68 hostile to wear pressure driven oil.
5) If there are destructive gas clients, the electrical control bureau ought to be introduced in the activity room segregated from destructive gas to stay away from harm to the electrical parts and influence ordinary work (different clients can introduce it as indicated by their necessities); make sure that the wiring of the power supply and engine is right, then, at that point, turn the power on and check the electrical control bureau once more.
(6) When lifting the channel press, the region in touch with the lifting ought to be fixed with texture or other delicate material.
VI. Support of the channel press
The support of the channel press is vital during the time spent use. It is important to grease up and keep up with the matching parts and transmission parts, particularly the criticism signal place of the programmed control framework (electrolytic contact pressure check and travel switch, and so forth) and the precision and unwavering quality of the water driven parts of the pressure driven framework should be guaranteed in order to keep up with ordinary work, for which the accompanying focuses ought to be finished.
1) Check cautiously consistently whether the associations are firm and regardless of whether the parts are in great use, and inform support staff of any anomalies found for redesign.
(2) The orientation, cylinder poles and different parts ought to be checked consistently so the mating parts are kept spotless and very much greased up to guarantee adaptable development.
(3) The electrical control framework ought to be routinely tried for protection and unwavering quality, and the electrical parts ought to be fixed or supplanted instantly in the event that helpless exactness or firmness is found.
(4) The support of the pressure driven framework is chiefly the investigation and upkeep of the water powered parts and the fixing at the point of interaction.
5）The fixing surface of the channel plate ought to be checked much of the time to guarantee that it is cleaned and clean; prior to squeezing, filter press manufacturer the channel material ought to be painstakingly checked to guarantee that it is liberated from collapsing, breakage and slag, so it is level and flawless to guarantee the sifting impact, while the channel fabric ought to be flushed every now and again to guarantee the separating execution of the channel fabric.
6) If the channel plate isn’t utilized for quite a while, it ought to be cleaned and perfectly released on the casing of the channel press and squeezed with 1-5MP tension. The channel fabric ought to be cleaned and dried in the sun, and the uncovered piece of the cylinder ought to be covered with oil.
7) Use HM46 or HM68 water powered oil, and it should be kept clean. The water driven oil ought to be supplanted once when the new machine runs for multi week interestingly, and the involved water driven oil in the oil tank and chamber ought to be released neatly while replacing the oil. The water powered oil should be supplanted following one month of utilization, and it is prescribed to supplant it once at regular intervals to guarantee the ordinary utilization of the channel press.
- Notes on the channel press
(1) Please read the guidance manual cautiously before use.
(2) Check cautiously whether the channel fabric particulars meet the interaction prerequisites, regardless of whether there is any harm, and whether it is level and crease free when introduced.
(3) Check whether the channel plate is accurately organized and regardless of whether the fixing surface is spotless.
4) After the channel press is squeezed, begin dealing with the feed siphon. The feed pressure should be controlled beneath the appraised tension on the name, if not it will influence the ordinary utilization of the channel press.
5) At the start of filtration, the feed valve ought to be opened gradually. The filtrate is frequently shady right away and afterward turns clear, which is a typical peculiarity.
(6) When flushing the channel plate and channel material, be mindful so as not to sprinkle water on the pressure driven station and the electric control cupboard.
(7) The flood valve has been changed prior to leaving the production line, assuming that the client needs to change the functioning tension without help from anyone else, he ought to change the flood valve all freely, then, at that point, start the oil siphon and gradually change the flood valve to the necessary strain, yet can’t surpass the greatest tension determined by the machine.
(8) When supplanting the channel plate, crash is totally restricted to stay away from harm; the channel plate ought not be taken out without authorization to stay away from harm to the machine because of the cylinder bar surpassing the stroke; the channel plate ought to be supplanted in time when it is harmed, any other way it will make harm other channel plates.
(9) Hydraulic oil with HM46 or HM68 oil, through the air channel into the tank, should arrive at the predefined level; tank ought to be shut well to forestall trash and sewage into the tank, so the water driven parts rust disappointment.
(10) The electric control bureau ought to be kept dry, and a few electrical parts, for example, pressure measure and solenoid valve loop ought to be checked routinely to guarantee typical activity of the gear.
(11) Switch off and remove the power supply after work to guarantee wellbeing.
