Pressurizing stacked disc filter

Abstract

The invention relates to the technical field of filtering equipment, in particular to a pressurizing stacked disc filter which comprises a pressurizing bin, a supporting frame is arranged in the pressurizing bin; a slurry tank is fixed on the supporting frame; a main shaft is horizontally and rotatably mounted on the supporting frame; a plurality of filter discs are fixedly mounted on the main shaft; a first motor is mounted at one end of the main shaft; the first motor drives the main shaft to rotate, a safety valve is mounted at the top of the pressurizing bin; a buffer bin is arranged at the bottom of the pressurizing bin; a discharging device is arranged below the buffer bin; the discharging device comprises a second motor and a discharging bin, and a screw rod second motor is mountedat one end of the discharging bin. The pressurizing stacked disc filter solves the problems that the existing pressurizing filter is large in appearance and size, large in occupied space and difficultto operate and maintain, and in the working process, feeding and discharging bring out part of air pressure in the pressure tank and thus the air pressure in the pressure tank is less than a standardvalue and extremely-fine-fraction coal particles less than 320 meshes cannot be filtered out.

Description

technical field [0001] The invention relates to the technical field of filtering equipment, in particular to a pressurized disc filter machine. Background technique [0002] The pressure filter is a new type of high-efficiency fine-grained coal dehydration equipment. It uses compressed air as the driving force of the filter to form a pressure difference on both sides of the filter medium, so that the material forms a filter cake on the filter disc, and then uses the wind blowing and scraper Unload the filter cake to the discharge bin. Since the upper and lower sealed discharge bins work alternately, the equipment can work continuously, with large processing capacity and low product moisture. It is widely used in coal preparation plants. The pressurized filters currently on the market are basically simply set the equipment In a large pressure tank, the compressed gas is simply fed into the work. This type of equipment has a large appearance and volume even if it is a small-a...

AI Technical Summary

Problems solved by technology

[0004] Solve the problem that the existing pressurized filter has a large shape, occupies a large space, and is difficult to operate and maintain. In addition, during the working process, a part of the air pressure in the pressure tank will be brought out by feeding and discharging, resulting in The air pressure is less than the standard value, and can not filter out the problem of ultra-fine coal particles smaller than 320 mesh, a pressurized stacked disc filter is provided
