Filter press is a kind of intermittent pressure filtration equipment, used in all kinds of suspending liquid’s solid-liquid separation. Separation effect is good.It is easy to use and widely used in petroleum, chemical industry, fuel, metallurgy, pharmacy, food, paper making, coal washing and sewage treatment, and other solid-liquid separation fields. Mechanical pressure filter could make the progress of pressure, filtering and washing, cross washing, blow dry, loosen. It has the filter board which could reinforced the squeezing of polypropylene, rubber, cast iron, stainless steel, the diaphragm and other material and structure.
1.the low pressure filter, high pressure squeezing, can greatly shorten the cycle of the whole filter.
2.the TPE elastomer, can achieve maximum pressure filter 25 MPA, so that the moisture content is reduced greatly, save drying cost and improve the yield.
3.save the power of the operation cost, the late in filter, small flow, high pressure.
4.the diaphragm squeezing function, in a very short time to complete this a process, save the power consumption.
5.promote the mud cookies degrees, reduce the mud cake containing rate, the diaphragm squeezing the static filter after the end of the filter cake in secondary crushing, make the structure of the filter cake rearrangement, send density increase, and the replacement of moisture, improve the dry degree.
6.corrosion resistance is strong, basic applies to all solid-liquid separation homework
The structure of filter press
The filter press frame is fabricated of ASTM-A36 carbon steel plate and structures. Weldments shall be open gusset construction for maximum strength and ease of maintenance. All weldments shall be designed to evenly distribute the operational forces developed during filtration over the entire component. All structural components shall be continuously welded for maximum strength. Intermittent welding of structural joints shall not be acceptable. All components shall be designed with a minimum safety factor of 1.5 times the maximum closure force. Critical assembly points such as sidebar connections shall be machined to close tolerances to ensure uniform load distribution at all stress bearing areas.
Filter plates is molded from virgin, gray polypropylene and shall contain no fillers. Plates shall have a drainage surface design that shall provide adequate support for filter cloths and shall have integrally molded stay boss supports equally spaced on the drain field. Plate sealing surfaces shall be machined to a maximum parallel plane tolerance of .3 mm. Chamber recess depth dimension shall have a tolerance not to exceed .5 mm.
