When the electromagnetic exhaust valve needs to be overhauled or replaced, the maintenance ball valve is closed, and then the quick operation can be carried out.

Description

Blockage clearing and circular blowing system for ash bucket of bag type dust collector

Technical Field

The invention belongs to the technical field of industrial dust removal, and particularly relates to a blockage removing and circular blowing system for an ash bucket of a bag type dust collector.

Background

In the ash bucket of the bag type dust collector, materials are often extruded to form an arch and blocked at the centrum part of the ash bucket, so that the continuous conveying of the materials is influenced. At present, an air cannon is often used for breaking an arch part of a material, but after the air cannon is used each time, a small part of fine particles raised by impact in an ash bucket reversely enter the air cannon, and are deposited in the air cannon and reduced in effective volume as time passes, so that the reason why the impact force of the air cannon is reduced gradually in the use process is also considered; in addition, the impact direction of the air cannon is only one, the dust hopper of the dust remover is provided with four wall surfaces, and the influence range and the actual effect of the air cannon are not ideal.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention aims to provide a blockage removing and circular blowing system for a dust hopper of a bag type dust collector, so as to improve the impact effect.

In order to achieve the purpose, the invention adopts the technical scheme that:

a blockage clearing and circular blowing system for an ash bucket of a bag type dust collector comprises a main blowing ring pipe which is arranged on the upper part of a discharge port of the ash bucket of the dust collector in a surrounding manner, wherein a plurality of blowing branch pipes which are inserted into the inner wall of the ash bucket in a downward inclined manner are connected to the main blowing ring pipe, and compressed air is introduced into the main blowing ring pipe.

And the communicating pipe between the injection main ring pipe and the compressed air is provided with an air storage bag, and the communicating pipe between the air storage bag and the injection main ring pipe is sequentially provided with an electromagnetic exhaust valve, an overhaul ball valve and a pressure regulating valve.

The air storage bag is arranged at the position 800-1000 mm above the blowing main ring pipe.

The pressure of the compressed air is 0.4-0.8 MPa.

The main blowing ring pipe is arranged 300-600 mm above a discharge port of an ash bucket of the dust remover and is a communicated air pipe horizontally surrounding the wall surface of the ash bucket for one circle.

The dust remover ash bucket is provided with a plurality of wall surfaces, a blowing branch pipe is arranged at the midpoint of a blowing main ring pipe on each wall surface, the blowing openings of two blowing branch pipes on the opposite wall surfaces are arranged in a matched mode, and the vertical height difference is 300-500 mm.

Compared with the prior art, the invention has the beneficial effects that:

(1) the reverse flying of fine particles after can effectively avoid the jetting gets into the gas storage package.

(2) The action area is larger than that of the prior art such as an air cannon when the downward impact arch breaking is carried out.

(3) The movable part in the system has small inertia, impact resistance and long service life.

(4) Simple process and low investment cost.

Detailed Description

The embodiments of the present invention will be described in detail below with reference to the drawings and examples.

As shown in figures 1 and 2, the invention relates to a blockage clearing and circular blowing system for an ash bucket of a bag type dust collector, which comprises a main blowing ring pipe 6, wherein the main blowing ring pipe 6 is arranged at the position of about 300-600 mm above the discharge opening of the ash bucket 1 of the dust collector in a surrounding manner and is a communicating air pipe horizontally surrounding the wall surface of the ash bucket for one circle, and the main blowing ring pipe 6 is connected with a plurality of blowing branch pipes 7 obliquely inserted into the inner wall of the ash bucket downwards.

In the embodiment shown in the invention, the dust hopper 1 of the dust collector is provided with four wall surfaces, the middle point of the main blowing ring pipe 6 on each wall surface is provided with one blowing branch pipe 7, the blowing openings of the blowing branch pipes 7 on two opposite wall surfaces are arranged in a matched mode, the vertical height difference is preferably 300-500 mm, and a larger action area can be obtained when the arch is broken by downward impact.

Compressed air is required to be introduced into the blowing main ring pipe 6, and the pressure of the compressed air is generally 0.4-0.8 MPa. Its communicating pipeline with compressed air is provided with gas storage package 2, and gas storage package 2 arranges in the upper portion 800 ~ 1000mm department of jetting main loop pipe 6, through arranging gas storage package 2 in clear stifled ring system top, jetting main loop pipe 6 is located clear stifled ring system middle part and is regarded as the buffer zone, can effectively avoid jetting back fine particle thing reverse fly upward get into gas storage package 2, and also can in time clear away the deposition in the main loop pipe when the ring blows the operation at every turn.

Compressed air with certain pressure is stored in the air storage bag 2, when the electromagnetic exhaust valve 3 is opened quickly, the compressed air in the bag reaches the sound velocity (under the condition of proper pressure), is distributed to each injection branch pipe 7 along the injection main ring pipe 6, and then obliquely downwards impacts along each injection branch pipe 7 to break the arch. The communicating pipe between the gas storage bag 2 and the blowing main ring pipe 6 is sequentially provided with an electromagnetic exhaust valve 3, an overhaul ball valve 4 and a pressure regulating valve 5, and when the electromagnetic exhaust valve 3 needs to be overhauled or replaced, the overhaul ball valve 4 is closed to carry out rapid operation.
