Water washing diaphragm filter press

Abstract

The invention discloses a water washing diaphragm filter press. The filter press comprises a bracket, the upper end of the bracket is fixedly connected with a rack; the upper end of the rack is fixedly connected with a main beam; a thrust plate, filter plates and a pressing plate are sequentially mounted on the main beam from left to right; and sliding rails are welded to the outer side faces of the main beam. A walking trolley is slidably connected to the sliding rails. The walking trolley is fixedly connected with the front side of the filter plates; the filter plates are connected through flexible chains; flushing mechanisms are fixedly connected to the left and right sides of the upper end of the main beam; a driving motor is installed on the right side of the lower end of the main beam, an output shaft of a driving motor is connected with a driving wheel, the driving wheel is connected with a driven wheel through a belt, the left side of the driven wheel is fixedly connected witha turning plate located below the main beam, the front and rear sides of the turning plate are rotationally connected with the rack; and a transmission mechanism is arranged under the turning plate. The filter press has the advantages that the discharging impact force is reduced, the service life of a material receiving mechanism is prolonged, the discharging efficiency is high, the filter platesis cleaned in time, the service life of the filter plates is prolonged, and filter cakes and flushing water are transferred out in time.

Description

technical field [0001] The invention belongs to the technical field of filter presses, in particular to a water flushing diaphragm filter press. Background technique [0002] The filter press uses a special filter medium to apply a certain pressure on the object to make the liquid dialysis out. It is a kind of commonly used solid-liquid separation equipment. A filter press chamber is formed between the filter plates. Impurities are pressed into filter cakes. After the press filtration is completed, the filter cakes fall from between the filter plates to realize unloading. The filter cakes fall directly onto the material receiving mechanism with a large impact force, which is easy to damage the material receiving mechanism. The mechanism cannot transfer the filter cake out in time, and it is left on the material receiving mechanism for a long time, resulting in a decrease in the discharge efficiency. After the discharge is completed, the inner surface of the filter plate need...

[0002] The filter press uses a special filter medium to exert a certain pressure on the object to make the liquid dialysis out. It is a kind of mechanical equipment commonly used for solid-liquid separation, and a filter press chamber is formed between the filter plates. Impurities are pressed into filter cakes. After the pressing is completed, the filter cakes fall from between the filter plates to realize unloading. The filter cakes fall directly onto the material receiving mechanism with a large impact force, which is easy to damage the material receiving mechanism, and the material receiving mechanism The mechanism cannot transfer the filter cake out in time, and it is left on the material receiving mechanism for a long time, resulting in a decrease in the discharge efficiency. After the discharge is completed, the inner surface of the filter plate needs to be washed to wash down the filter residue particles remaining on the inner surface of the filter plate. To prevent the service life of the filter plate from being shortened due to the filter residue particles on the filter cloth and the filter press effect of the filter press, a large amount of water resources are consumed during the flushing process, and the flushed water is not collected for recycling, which wastes a lot Therefore, it is urgent to design a filter with good shock absorption effect, reduce the impact force of unloading, prolong the service life of the material receiving mechanism, high unloading efficiency, clean the filter plate in time, have a good filter press effect, and prolong the filter life. The service life of the plate, the timely transfer of the filter cake and flushing water, the recycling of the flushing water, and the water-saving membrane filter press for water flushing
