Water guide and cake unloading device of sludge high-dry dehydration filter press

Abstract

The invention belongs to the field of sludge treatment, and particularly relates to a water guiding and cake discharging device for a sludge high-dry dehydration filter press. The water guiding and cake discharging device comprises a guide groove arranged below a filter press filter plate assembly, wherein the guide groove has a pocket structure made of a flexible waterproof fabric, two ends of the bottom of the guide groove are obliquely arranged, a notch of the guide groove is an opening-closing type, when the notch of the guide groove is opened, the guide groove can bear materials falling from the filter press, and when the notch of the guide groove is closed, the guide groove can avoid the materials falling from the filter press. The water guiding and cake discharging device for the sludge high-dry dehydration filter press abandons the structure of the original universal water guiding and cake discharging device, water guiding and sludge discharging channels are separated by adopting the flexible waterproof guide groove arranged in an opening and closing manner, water drops do not splash during a water guiding process, the dehydration quality of sludge cakes can be guaranteed, and the equipment cost can be lowered.

Description

technical field [0001] The invention belongs to the field of sludge treatment, and in particular relates to a water guiding and cake unloading device for a high-dry sludge dehydration filter press. Background technique [0002] In the field of sludge treatment, the treated sludge needs to be dehydrated to separate dry and wet substances for subsequent landfill or recycling. In the prior art, a filter press is usually used to dehydrate the mud. The main structure of the filter press includes multi-layer laminated filter press assemblies, each filter press assembly is placed vertically, and the space formed between each filter press assembly The cavity constitutes the extrusion cavity. During dehydration, the mud is poured into the extrusion cavity, and then the pressure is applied to the filter plate, the water in the mud will overflow from the pores set on the filter plate, and finally flow out from the bottom of the filter plate. After the dehydration is completed, the fi...

AI Technical Summary

Problems solved by technology

However, the disadvantages of the above-mentioned water guiding and unloading device are: firstly, the overflowing water flow during dehydration and the mud cake falling during discharge are all in contact with the upper surface of the turning plate, so when the turning plate is switched from guiding water flow to guiding mud cake At this time, the mud cake will inevitably be stained with a large amount of water, which will affect the dehydration effect. Similarly, when the flap is switched from guiding the mud cake to guiding the water flow, the soil adhered to the flap will enter the drainage system with the water flow, causing the drainage system to Fouling and blockage; In addition, the above-mentioned flaps a1, a2 and water tanks b1, b2 are all welded by metal materials, which are prone to sputtering during diversion, and will be severely corroded after long-term use, resulting in water leakage and seriously affecting On-site production environment
