Problems solved by technology

[0002] When the existing shut-off fan separates the particles, it is generally a one-stage type, which will cause two situations in the separation process of the particles, one is that the separation wind speed is too high, and the large particles are taken away directly; the other is the separation wind speed Too small, the separation of small particles is not clean

Abstract

The invention relates to a rotary valve. The rotary valve comprises a dust removal device (6), an air pipe (5) and a sedimentation dedusting device (1). The dust removal device (6) comprises an inclined dust removal passage (61), and the top of the dust removal passage (61) is provided with a feeding port (63) while the top of the dust removal passage (61) is provided with a discharging port (64). The upper side of the dust removal passage (61) is provided with a funnel shaped connection port which is connected with the discharging port (64), and a plurality of air adjusting valves (7) are arranged on the lower side of the dust removal passage (61). The sedimentation dedusting device (1) is a cubic shell with the bottom connected with a 'V'-shaped funnel (103), the lateral surface of one end of the sedimentation dedusting device (1) is provided with a sedimentation outlet (101) while the lateral surface of the other end of the sedimentation dedusting device (1) is provided with a sedimentation inlet (102), a housing (3) is arranged outside the sedimentation dedusting device (1), and the sedimentation outlet (101) is connected with an external dust collector. The rotary valve is simple in structure and high in dedusting efficiency.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a multi-stage dust removal shut-off fan. Background technique [0002] When the existing shut-off fan separates the particles, it is generally a one-stage type, which will cause two situations in the separation process of the particles, one is that the separation wind speed is too high, and the large particles are taken away directly; the other is the separation wind speed If it is too small, the separation of small particles will not be clean. [0003] In view of the above-mentioned defects, the designers are actively researching and innovating in order to create a novel structure of shut-off fan, so that it has more industrial utilization value. Contents of the invention [0004] In order to solve the above technical problems, the object of the present invention is to provide a shut-off fan capable of removing a lot of dust. [0005] Technical scheme of the present invention is as f...
