Product Overview:This machine is stainless steel multilayer frame filter press, apply to concentrations of less than 50% low viscosity liquid containing less of the amount of slag sealed filter in order to achieve the fine filter of purification, sterilization, clarification, and de-activated carbon, in addition to particle semi-fine filter require... Product Overview:This machine is stainless steel multilayer frame filter press, apply to concentrations of less than 50% low viscosity liquid containing less of the amount of slag sealed filter in order to achieve the fine filter of purification, sterilization, clarification, and de-activated carbon, in addition to particle semi-fine filter requirements, the direct selection of a microporous membrane, without the microporous membrane filters can achieve the purpose of the sterile filtration). Filter area of the machine, flow rate, the scope of a wide range of applications in the pharmaceutical, chemical and food industries, pharmaceutical factory injection liquid filtration applications, very good results.Technical parameters:Model the BL-100BL 150BL-200BL-300 Specification (mm) Ф100Ф150Ф200Ф300 layers 10,101,010 filtration area (m2) 0.0780.170The the 0.3140.7 membrane pore size (um) 0.80.80.80.8 filter pressure (Mpa) 0.150.150.150.2 water flow (T / h) 0.8 View Details

Latitude blessing filter operation is simple, use only the required fineness grades of filter bags installed in the cartridge, check the O-ring is intact, and then tighten the cartridge cover ring bolts can work.Pump starts, the pressure gauge on the filter a slight rise in the initial pressure of about 0.05MPa tank residues gradually increased with the use of time, should be shut down when the pressure reaches 0.4MPa, open the cylinder cover, check the filter machine bag stay residue can replace the filter bag to continue to use (filter bag cleaning generally can be reused).filter press is generally adjusted in 0.1-0.3MPa more appropriate return valve on the return line or the pump to adjust the filter pressure is too high will damage the filter bag and the protection of networks need to pay particular attention to.

Diaphragm filter press works

Diaphragm filter press and the ordinary Van filter main difference between the filter plates and filter cloth fitted with a layer of semi-automatic membrane filter press - compound rubber plate elastic membrane.

Diaphragm filter press and the ordinary Van filter main difference between the filter plates and filter cloth fitted with a layer of semi-automatic membrane filter press - compound rubber plate elastic membrane. During the operation, when the end of the feeding of high-pressure fluid medium injected between the filter plate and the diaphragm, this time the entire diaphragm will muster the oppression of cake in order to achieve the further dehydration of the cake is to crush the filter.The first positive-pressure extreme pressure dehydration, also called into the pulp dehydration, a certain number of filter plates in the role of strong mechanical forces are tightly arranged in a filter chamber is formed between the filter plate surface and the filter plate surface, the filter material in the strong under positive pressure into the filter chamber into the filter chamber, filter materials the solid part of the filter media (such as cloth) interception form a filter cake, the liquid portion of the discharge through the filter media filter chamber, so as to achieve the purpose of solid-liquid separation, With the positive pressure pressure increases, the solid-liquid separation is even more thorough, but the energy and cost considerations, pressure is not worth the high positive pressure.Into the slurry dewatering, equipped with a rubber squeeze film filter, compressed media (such as gas, water) into the back of the squeeze film to promote the squeeze film to squeeze the filter cake further dehydration, called the squeezing out of water. Into the pulp dehydration or squeezing out of water, compressed air enters one side of the cake of filter chamber through the filter cake, to carry the other side of the liquid water from the filter cake discharge filter chamber through the filter cloth and dehydration, is called the wind and dehydration. If the sides of the filter chamber are deposited there cloth, the liquid portion of the absorbed through the filter chamber the sides of the filter cloth to discharge filter chamber for the filter chamber sided dehydration.Dehydration is complete, lift the mechanical pressing force of the filter plate, a single block gradually pull the filter plate, respectively, open the filter chamber for cake discharge for a major cycle is complete. Depending on the nature of the filter materials, filter presses can be set into the pulp dehydration, squeezing out of water, wind and dehydration or single-, double-sided dewatering, the purpose is to minimize the filter cake moisture.

Fully mixed after a concentrated sludge with a concentration of flocculant in the static, dynamic mixer, small solid particles in the sludge poly cemented larger floc clumps, while separation of free water, flocculation The sludge is transported to the filter to bring concentrated gravity dehydration of free water under the action of gravity separation, the formation of sludge does not flow state, and then clamped between the upper and lower two mesh belt, after the wedge-shaped pre-pressure area, low pressure area and the high pressure area from small to large extrusion pressure, the effect of shear stress, and gradually squeezing the sludge, in order to achieve the greatest degree of mud, water separation, and finally the formation of filter cake discharge.1, Belt filter press the chemical pretreatment dehydrationOrder to improve the nature of the sludge dewatering, improved cake, increase the permeability of the material, the need for chemical treatment of sludge, this machine uses a unique water flocculation granulation mixer device in order to achieve the chemical dosing flocculation The role of this method is not only good flocculation can also save a lot of pharmaceutical, low operating costs, economic efficiency is very obvious.2, the gravity dewatering sectionSludge sent to the network through the cloth bucket uniform belt, with the filter, the sludge with a forward run, free water, then sink under its own weight through the filter strip inflow gravity dehydration can also be said to be highly concentrated segment, the main role is to take off the sludge the free water, so that the flow of the sludge decreases, to prepare for further squeeze.3, Belt filter press wedge pre-pressure dewateringGravity dehydration of sludge flow is almost completely lost, with the belt filter press filter with forward run with a spacing of the upper and lower filter is gradually reduced, the material began to be a slight pressure and run with the filter with pressure gradually increasing The role of the wedge-shaped area is to extend the gravity drying time, increase the extrusion stability of the floc, and prepare for entry into the pressure zone.4, squeeze rollers of high-pressure dewateringMaterial from the wedge into the pressure zone, by squeezing the material in this region, with the running direction of the pressure increase with the reduction of the squeeze roller diameter along the filter material by the extrusion volume shrinkage, free water clearance within the material being squeezed out At this point, the basic formation of filter cake, continue to move forward to the high-pressure zone of the pressure on the tail after a high-pressure after the filter cake moisture content can be reduced to a minimum.5, the material dischargeMaterial formed after the treatment of various stages of dehydration cake discharge by scraper scraped the upper and lower filter with separate after high-pressure rinse water to remove trace materials in the filter hole, continue to enter the next step dehydration cycle.
