Problems solved by technology

[0008] Aiming at the problems existing in the prior art, the object of the present invention is to provide a combined frame plate for a plate-and-frame filter press, which can realize the combination of a traditional filter press plate and a diaphragm filter plate, so that the filter press The plate not only has the function of filtering water, but also has the function of compressing the filter press chamber by the diaphragm filter plate, which can improve the space utilization efficiency of the filter press, enable the filter press to install more filter press plates, and indirectly improve the quality of the filter press. The overall filtration efficiency, and using the push plate instead of the traditional diaphragm compression, improves the overall service life of the diaphragm filter plate, and when the push plate is compressed, there will be no uneven compression of the diaphragm, and through the push plate and The combined use of the flow-limiting tube enables the sludge entering the filter press chamber to fill up the filter press chamber first and then enter other press filter chambers, avoiding the occurrence of empty bags when filling sludge into the filter press chamber and affecting the filter press effect

Abstract

The invention discloses a combined frame plate for a plate-and-frame filter press, belongs to the technical field of plate-and-frame filter presses, and can combine a traditional filter pressing plate with a membrane filter plate for use, so that the filter pressing plate has the function of filtering water and also has the function of compressing a filter pressing chamber of the membrane filter plate. Therefore, the space use efficiency of the filter press can be improved, more filter pressing plates can be installed on the filter press, the overall filtering efficiency of the filter press is indirectly improved, the push plate is used for replacing traditional membrane compression, the overall service life of the membrane filter plate is prolonged, and the situation of non-uniform membrane compression is avoided when the push plate is used for compression. Through cooperative use of the push plate and a flow limiting pipe, the sludge entering the filter pressing chamber can fill the filter pressing chamber firstly and then enter other filter pressing chambers, so that the phenomenon that the filter pressing effect is influenced by empty bags when the sludge is filled into the filter pressing chamber is avoided.

Description

technical field [0001] The invention relates to the technical field of plate and frame filter presses, and more specifically, relates to a combined frame plate used for a plate and frame filter press. Background technique [0002] Plate and frame filter press is the first machine used in chemical dehydration. Although the plate and frame filter press is generally operated intermittently, the investment in infrastructure equipment is large, and the filtration capacity is also low, but because of its strong filtration driving force, high solid content of filter cake, clear filtrate, high solid recovery rate, conditioning medicine Advantages such as less consumption. [0003] A plate and frame filter press is usually equipped with multiple filter press plates, and a diaphragm filter plate is arranged between every two filter press plates. [0004] Both sides of the filter press plate are covered with filter cloth, and the plate and frame are pressed tightly by a pressing devi...
