Filter belt's tension adjustable full-automatic belt vacuum filter

Abstract

A filter belt's tension adjustable full-automatic belt vacuum filter belongs to solid-liquid separation equipment. The filter of the invention comprises a rack, a filter belt distributing mechanism, a solid-liquid separation vacuum-pumping mechanism, a filter belt correction mechanism, a filter belt cleaning mechanism, a filter cake removing mechanism, a pair of filter belt tension adjusting mechanism, a filter belt driving mechanism and a filter belt. The invention is characterized in that front and rear ends of a tension roller are supported on a tension roller supporting spindle head; each filter belt tension adjusting mechanism comprises a tension roller supporting spindle head adjusting seat, an adjusting screw seat, an adjusting screw and a plug-pin; the tension roller supporting spindle head adjusting seat is fixed on the rack; one side of the tension roller supporting spindle head adjusting seat is provided with a tension roller supporting spindle head adjusting groove; the adjusting screw seat is arranged inside the tension roller supporting spindle head adjusting groove and is provided with an adjusting screw hole and a pin hole; the tension roller supporting spindle head is provided with a supporting spindle head screw hole; the adjusting screw is spirally arranged on the adjusting screw seat; the plug-pin is plugged-in the pin hole; and the rack is provided with a filter cake thickness measuring sensor. The filter of the invention has advantages of simple structure, convenience in processing, fast adjusting speed, high efficiency and high adjusting accuracy.

Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation equipment, and in particular relates to a fully automatic belt-type vacuum filter with adjustable filter belt tension. 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 t...
