Rubber band filter

Abstract

The invention provides a rubber band filter. A rubber band is mounted on a rack through a driving roller, a driven roller and a tensioning roller; filter cloth is mounted above the rubber band; a filter cloth pressing roller is arranged at the upper part of the filter cloth; a discharging hopper is mounted above the left side of the filter cloth; isolators are uniformly distributed on the filter cloth; vertical roll devices are arranged on side surfaces of the rubber band; a rinsing hopper is arranged above the filter cloth; lifting devices, rubber band bearings, rubber band carrier rollers and a friction tape are arranged at the lower part of the rubber band; a bend roller and a scraping device are arranged on the right side of the rubber band bearings; vacuum boxes are connected with the rubber band through pipelines; automatic liquid discharging tanks are arranged on one side surface of the rack; a washing tank is arranged on the right side of the rubber band; an automatic filter cloth rectifying device is arranged on the rack and connected with a control cabinet. The rubber band filter has the advantages that the equipment is combined with a precipitation method preparation process, the goal of continuity and automation of the process is achieved, the production quality and the yield are substantially improved, the equipment utilization rate and the production efficiency are improved, and the rubber band filter has innovativeness in preparation of a catalyst with a precipitation method and other aspects.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a rubber belt filter. Background technique [0002] The solid-liquid separation equipment in the preparation process of the catalyst precipitation method carrier such as gasoline and diesel ultra-desulfurization is generally a plate-and-frame, centrifugal, funnel or drum filter, which can only complete one-step process of zero-time filtration, ammonium exchange or water washing. They are all intermittent operations, and there are problems such as lengthy process, low degree of automation, low yield, unstable quality, etc. As the main catalyst process equipment, the filter has been plagued by the catalyst production industry. The existing equipment has greatly improved the quality and production efficiency of the catalyst filtration process, but it cannot achieve zero-time filtration, ammonium exchange or continuous water washing processes.
