Description

A kind of combined type angle charging chamber filter plate and tapping method

Technical field

The present invention is filter plant filter press field, in more detail, be related to a kind of combined type angle charging chamber filter plate and Tapping method.

Background technology

Chamber filter plate is the primary filter element of filter press, and material filtering selects the charging of chamber filter plate and discharge opeing form pair The effect of filtration is extremely important, and current material filtering commonly uses chamber filter plate central well and enters filter chamber, by filter chamber Particle in filter cloth retention material forms filter cake, and filtrate is discharged by corner fluid hole, realizes the purpose of separation of solid and liquid.

Due to expanding economy, the material variety that separation of solid and liquid industry is filtered gradually increases, and material filtering contains to filter cake The requirement of water rate is more and more lower, and some chemical industries are washed to improve the degree of purity of filter cake to filter cake, or by washing filter Increasing the rate of recovery of filtrate, reduces cost improves the common demands that filter efficiency is user, therefore the van-type for using at present to cake The material that filter plate has is far from suitable when filtering, and filter cake moisture content is high, and the rate of filtration is slow, does not reach material filtering effect, it is impossible to Meet the filtering requirement of user.

The content of the invention

The invention aims to solve weak point present in above-mentioned background technology, and provide a kind of combined type angle Charging chamber filter plate and tapping method.

To achieve these goals, the present invention provides a kind of combined type angle charging chamber filter plate and tapping method, the combination Formula angle charging chamber filter plate arranges mainboard and matching board, and mainboard and matching board two pieces are combined as a set of；

（1）Mainboard is set, and described mainboard both sides arrange outer across ear, described outer across ear setting angle feeding-passage, arrange Charging hole, described charging hole joint angle feeding-passage arranges tap hole, and described tap hole connects charging hole, and described divides Discharge orifice is also connected with combining the filter chamber of filter plate both sides, arranges undercurrent hole, and described undercurrent hole is arranged outside across ear, arranges fluid hole, Described fluid hole connection undercurrent hole, in filter chamber lower corner multiple outages, described outage connection fluid hole, at angle are arranged Feeding-passage and undercurrent hole arrange rubber seal.

（2）Matching board is set, and described matching board appearance and size is consistent with mainboard combination, arranges outer across ear, described is outer across ear The outer both sides of matching board are arranged on, undercurrent hole is set, described undercurrent hole is arranged outside across ear, arranges fluid hole, described fluid hole Connection undercurrent hole, arranges outage, described outage connection fluid hole in filter chamber.

（3）Tapping method；Lead in the outage connection fluid hole of the angle feeding-passage direction lower end filter chamber lower corner of mainboard Cross undercurrent hole and discharge filtrate, the outage connection fluid hole of lower corner discharges filter by undercurrent hole on the right side of matching board filter chamber lower end Liquid, often covering the discharge of filter plate combination will be symmetrically installed according to lower end fluid hole, filter out liquid version for pressure and merge shape, right Claim shunting tapping method.

There are following advantages by the enforcement combined type angle charging chamber filter plate and its tapping method of the present invention；Combined type angle is entered Material chamber filter plate connects charging hole by mainboard angle feeding-passage makes filter material enter two filter chambers, tool simultaneously through tap hole There is filter chamber to form the fast effect of filter cake, the design of structure can install rubber seal, advantage in angle feeding-passage and undercurrent hole It is strong with high pressure resistant feeding seal performance, filter plate arranges outer across ear filter chamber increases effective filtration area, often covers combined type van-type The tapping method that filter plate is arranged symmetrically connects undercurrent hole discharge filtrate for two jiaos under mainboard and matching board, and with material filter chamber pressure is entered The balanced fusion of power, especially when filter cake is full of filter chamber feed pressure pressurize, filtrate discharges most uniform, pressure stability filter cake discharge opeing Without dead angle, symmetrical flow division formula tapping method filter cake can reach the minimum moisture content of squeezing filter cake, using the tapping method to filter Cake blowing discharges residual filtrate faster, makes filter cake moisture content lower better, if washed to filter cake, flushing water is passed through Tap hole enters the interspersed symmetrical flow division formula of filter chamber Jing pressure and discharges washings, and the degree of purity of filter cake can be greatly improved, and is gone out using this Liquid method clean result preferably, while can also increase the rate of recovery of filtrate, feeds chamber filter plate and goes out liquid using the combined type angle Method can reduces cost improve filter efficiency, meet user filtering requirement.
