Technical Field

[0001] The utility model belongs to the technical field of filter presses, and specifically relates to a dehydration filter press. Background Technique

[0002] Sludge treatment and disposal have the characteristics of multiple technical routes and high process integration. In recent years, the sludge drying and incineration process has developed rapidly due to its advantages of large volume reduction and relatively thorough treatment. Before sludge drying and incineration, it is generally necessary to first perform deep dehydration to reduce the moisture content of the sludge to a certain level. The traditional sludge deep dehydration uses a plate and frame filter press. After the sludge is conditioned by adding chemicals, it is filtered and dehydrated, and the dewatered sludge cake is then dried and incinerated.

[0003] In the prior art, the publication number 201611091555.7 discloses a plate and frame filter press device for additional electrolysis method deep dehydration of sludge, including a thrust plate, a pressing plate, filter plates and / or filter frames, cross beams, filter materials, a pressing device and a liquid collecting tank assembly. The modification is to convert the filter plates of the filter bag type plate and frame filter press into electrode assemblies, or convert the filter frames of the diaphragm type plate and frame filter press into electrode assemblies. The electrode assemblies at both ends of the filter press are connected to a DC power supply, and the other components and connection relationships of the filter press remain unchanged. The present invention is applied to sludge dehydration and has the following advantages: (1) The sludge can be deeply dehydrated to below 50%, which is convenient for direct external transportation and resource utilization of the sludge; (2) No secondary pollution is generated, no flocculant needs to be added, and the sludge volume is reduced; (3) The equipment is simple and the operation is convenient; (4) The electrode materials used have low cost and convenient electrode maintenance.

[0004] In the above patent, by converting the filter frame into an electrode assembly and connecting the electrode assemblies at both ends of the filter press to a DC power supply, the operation is convenient, the dehydration quality is improved, and the effect of avoiding secondary pollution is achieved. However, like the traditional filter press, this filter press is not convenient for cleaning dirt and replacing filter cloth after filtering sludge.

[0005] Therefore, a dehydration filter press is proposed for the above problems. Content of the Utility Model
