Abstract

Disclosed is an inflating board-frame filter press which uses elastic rubber diaphragm and filter cloth. At present, the elastic rubber diaphragm structure of the BKAY 65/820 type diaphragm inflating presser produced in China is complicated and is provided with small nuts, thus, when filter residue is pressed with compressed air, the phenomenon of air leakage and noise along with the discharging compressed air occurs. The utility model has the advantages of simple structure and energy saving. The filter plate, a filter frame, the filter cloth and the elastic rubber diaphragm are respectively fastened through fasteners at the filter plate and the slurry inlet of the filter frame. A gap is arranged between the fasteners in order that slurry passes the filter cloth to be filtered. The inflating board-frame filter press has the advantages of without noise of compressed gas discharging, little air consumption and stable gas pressure.

Description

Inflating board-frame filter pressor

The utility model belongs to plate and frame filter press.

The BKAY65/820 type membrane type inflation squeezer profile of Xuzhou Machinery Plant of Light Industry production at present is the garden formula, its flexible rubber dissepiment complex structure has little locknut, during with compressed air squeezing filter residue, there is gas leak phenomenon ， And to have Compressed Gas to discharge noise at little locknut place.

The purpose of this utility model is to adopt securing member to make flexible rubber dissepiment and filter frame tight-lipped solid in feed slurry, makes filter cloth and filter plate tight-lipped solid in feed slurry.Leave the space between the securing member, when supplying gas the squeezing filter residue, do not have gas leak phenomenon, do not have Compressed Gas to discharge noise with pressurized with compressed air.

The utility model is made of securing member (Fig. 1, Fig. 2), filter plate (Fig. 4), filter frame (Fig. 5), flexible rubber dissepiment, filter cloth and general front and back fixed head, portable plate, left and right sides crossbeam, automatic hydraulic system or gear drive or manual hold down gag, filter cloth and filter plate is fastening at filter plate feed slurry mouth with securing member (Fig. 3), flexible rubber dissepiment and filter frame is fastening at filter frame feed slurry mouth with securing member (Fig. 3).Leave gap (Fig. 6) at filter plate, the tight-lipped Gu Chu of filter frame feed slurry on the plane, filter by filter cloth so that slip enters between filter cloth and the flexible rubber dissepiment.Filter frame, the used material of filter plate can be with watering one of foundry goods, stainless steel, rubber or plastics.The used material of securing member can be with watering one of foundry goods, stainless steel, plastics or nylon.Filter plate, filter frame external form can be one of square, rectangle or garden type.Filter plate, filter frame, securing member forming method are can cast molding, sulfidization molding, injection mo(u)lding, extrusion die is molded or one of machining moulding.Used filter cloth can be one of canvas, fine canvas, woven dacron, silk.Used flexible rubber dissepiment can be one of flexible rubber dissepiment of common flexible rubber dissepiment, acid corrosion-resistant or alkali corrosion resistance.Thickness 2～8mm.

Use filtering technique of the present utility model to be: the liquid slip that contains the solid particle material, entering filter press feed slurry mouth by induction system arrives between filter cloth and the flexible rubber dissepiment, slip with flexible rubber dissepiment to the filter frame intermediate compression, slip constantly flows out clarified solution outside discharging opening outflow machine by filter cloth on the one hand, on the one hand by carrying the slip system constantly to replenish new slip, through certain hour or the minimizing of outflow clarified solution is that filter residue is after having piled up certain volume between flexible rubber dissepiment and the filter cloth, can stop charging, close inlet valve, the air that will have certain pressure with air compressor is supplied gas in filter frame from air inlet, the flexible rubber dissepiment of filter frame both sides changes outside extruding filter residue into to intermediate compression during by charging, reaches the purpose that the filter residue extruding is reduced content liquid.Because all compressed by filter plate, filter frame around filter cloth, the flexible rubber dissepiment, feed slurry mouth fastener is fastening, does not have the place that other can leak gas except that air inlet, thus supply gas when pressurizeing, pressure stability, air consumption is few, does not have Compressed Gas to discharge noise.Liquid outflow amount seldom after, stop to supply gas, after the frame internal pressure drops to normal pressure, unclamp pressing system, filter plate, filter frame, filter cloth, flexible rubber dissepiment are rinsed well, after reinstalling, prepare to filter to use next time.

The installation method of the utility model filter plate and filter frame is: with filter cloth that the two sides of filter plate is topped firmly, filter cloth is slightly bigger than filter plate, the feed slurry mouth of filter cloth and filter plate is fastening with securing member, be installed in the afterbody fixed head place of the nearly feed pipe of filter press frame, on fixed head, give the elastic caoutchouc that summary is bigger than filter plate be installed earlier, in case slip when filtering along the fixed head surface seep.With flexible rubber dissepiment that the two sides of filter frame is topped firmly, flexible rubber dissepiment is slightly bigger than filter frame, and is fastening with securing member at the feed slurry mouth of flexible rubber dissepiment and filter frame, is installed in the front of lastblock filter plate.During one of every installation, touch to the inside from the securing member material slurry-feeding mouth position with finger and check that filter plate and filter frame securing member have tight, if tight, should be with the securing member of filter plate, filter frame tightly to minimum range.Filter plate and filter frame are installed at interval, after last piece filter plate installs, push portable plate to sheet frame with transmission mechanism, and between portable plate and last piece filter plate the elastic caoutchouc that summary is bigger than filter plate are installed.Continuation is pushed portable plate to sheet frame, but and with its be compacted to liquid not from around spill just feed slurry and filter.

The utility model has the advantages that: used flexible rubber dissepiment is simple in structure, has used securing member at filter plate and filter frame material slurry-feeding mouth position, and is during Compressed Gas squeezing filter residue, air tight, air consumption is few, no Compressed Gas discharge noise.Filter plate, filter frame are by dress conveniently, and be easy to use, easily manufactured.
