Shanghai Dazhang Filtrate Equipment Co.,Ltd. products

In the step of second squeeze, membrane filter press adopts water pressure or compressed air press, the pressure could reach 0.8-2.0mpa, which will improve production efficiency greatly and reduce the moisture content of filter cake.
Membrane filter press is mainly used in papermaking, coking, medicine (antibiotics, calcium phytate, traditional Chinese medicine extraction, organic phosphorus, etc), food (stevia sugar, maltose, starch sugar, starch), chemical (dyes, pigments…) and other industries.

Full-automatic Program Controlled High Efficiency Filter Press controlled by  the microcomputer controller, PLC and touchscreen controller. It also has remote control interface and could achieve the automatic remote control operation. It is widely used for different industries because of the features compact structure, stable performance, high efficiency and low cost. It is widely used in industries, such as petrochemical, metallurgy(gold mine, silver mine, copper mine, iron mine, zinc ore rare earth, etc), grease(light oil, glycerin, machine oil, vegetable oil, etc), ceramics(bentonite, active earth, porcelain clay, etc)

DNY belt filter press is a kind of equipment can working continuously for solid-liquid separation. For solid-liquid separation to reduce the moisture content of materials what with high water content, convenience for the directly final disposal. There are two functions of this type of equipment, concentration and squeeze dewatering. It is a integrated system with two-level preloading for more concentrated dewatering. Step-less speed control for filter cloth driving motor, to secure procedure control of treating material quantity and water content. Widely used in these areas: municipal wastewater treatment plants, paper making, food, fine chemicals, mining, printing and dyeing, power generating, metallurgy, coal and other sewage treatment plant material dehydration conditions.

S.S. multilayer filter is for fine filtering. It is surface is polished, has seals, and normally used together with S.S. feeding pump. The suspended solution is pumped into filter chamber, under the feeding pressure, the filtrate pass through the filter media and then discharged from the outlet. The solid will becomes to filter cakes. Thus realized solid liquid separation. It is normally used for following industries: laboratory, fine chemicals, medicine chemicals, food, cosmetic and others industries of solid liquid separation and liquid filtration.

SS multilayer filter is a kind of filter equipment used for fine filtration, the machine with mirror polishing, use filter cloth and membrane as filter media, and use sealing strip for leakage; Suspension will be feed into the filter by feeding pump, the filtrate will through filter layer and filter media under feeding pressure, and come out from the outlets. Residue remain in chambers and form filter cake. Then realize solid-liquid separation.

A very important part of the filter press is filter cloth, and whether the filter press works ideally depends largely on the performance of the filter cloth and its ability to achieve solid-liquid separation without clogging and unbroken. According to different kinds of fiber, filter cloth can be classified two kinds: one is natural fiber, such as cotton, wool, silk, hemp fiber; the other is chemical synthetic fiber, such as polyester, nylon, , Polyester fiber and so on. According to the composition of the yarn, filter cloth can be divided into monofilament yarn, multifilament yarn, short fiber yarn. Monofilament woven fabric is not easy to be blocked, good cake unloading performance.

The feeding piston pump is a hydraulic pump that achieves oil absorption and pressure by means of a plunger in the cylinder for reciprocating movement to cause a change in the volume of the seal. Piston pump has the features of high pressure, compact structure, high efficiency, easy flow adjustment and so on. It is widely used in the occasion where high pressure, high flow and flow need to schedule, such as hydraulic presses, construction machinery and ships.

Multi-stage centrifugal pump adopts the country recommended highly efficient energy-saving hydraulic model, with advantages of high efficiency, wide range of performance, safe and stable operation, low noise, long life, easy installation and maintenance. By changing the pump material, sealed form and increase the cooling system, it can transport hot water, oil, corrosive and abrasive-containing media. This kind of pump is used in the factories, cities, mines, power plants, farmland, water conservancy projects and other fields, generally used for large flow low-head cycle water supply.
