Efficient energy-saving full-automatic belt type vacuum filter

Abstract

The invention discloses an efficient energy-saving full-automatic belt type vacuum filter, and belongs to the technical field of solid-liquid separation equipment. The efficient energy-saving full-automatic belt type vacuum filter comprises a rack, a solid-liquid separation vacuumizing mechanism, a filter belt correcting mechanism, a filter belt cleaning mechanism, a filter cake unloading mechanism, a pair of filter belt tension regulating mechanisms, a filter belt driving mechanism and a filter belt; the upper portion of the rack is provided with a filter disc which is provided with filter grooves, the groove bottoms are provided with filter groove drainage holes, the left end of the rack is provided with a front guide roller, a belt pressing roller, a tension guide roller and a tension roller, and the right end of the rack is provided with a back guide roller and a material scraping roller; the solid-liquid separation vacuumizing mechanism is connected with a drainage tank; the filter belt correcting mechanism is arranged on the lower portion of the rack; the filter belt cleaning mechanism is arranged on the lower portion of the rack; the filter cake unloading mechanism is arranged on the rack; the filter belt tension regulating mechanisms are connected with the tension roller; the filter belt driving mechanism is arranged on the lower portion of the rack; the filter belt sequentially passes through the filter belt correcting mechanism, the tension guide roller, the tension roller, the front guide roller, the belt pressing roller, the filter grooves, the back guide roller, the material scraping roller and the filter belt cleaning mechanism from the filter belt driving mechanism and then returns to the filter belt driving mechanism. The efficient energy-saving full-automatic belt type vacuum filter has the advantages that solid-liquid separation is achieved, and the storage and transportation requirements are met; filter belt deviation is avoided; energy saving is achieved; the cleaning time is saved; filter belt slipping is prevented; the whole device is simple.

Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation equipment, and in particular relates to a high-efficiency, energy-saving and full-automatic belt-type vacuum filter. Background technique [0002] In order to protect the environment, coal is used as energy in the iron and steel production industry, thermal power generation industry, metallurgical industry, pharmaceutical and chemical industry, heating industry and even mineral processing industry, etc. 2 The flue gas is desulfurized. Coal-based thermal power plants, for example, generally use wet limestone or gypsum desulfurization. Wet limestone or gypsum desulfurization process includes absorption of SO 2 , sulfite oxidation, and gypsum separation and dehydration. The vacuum filter is an indispensable equipment for the gypsum dehydration and separation process. Its mechanism of action is to remove the moisture in the gypsum slurry after the reaction of the absorption tower thr...
