Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a bag dust collector which is easy to clean. Background Art

[0002] A bag dust collector is a device that separates dust from flue gas. A bag dust collector is also called a filtering dust collector. It is a dust removal device that uses bag filter elements made of fiber woven materials to capture solid particles in dust-containing gas. Its working principle is that dust particles are intercepted by colliding with fibers due to inertia when they pass around the filter cloth fibers. The filter bag is made of textile filter cloth or non-textile felt, and the dust-containing gas is filtered by the filtering effect of fiber fabric. When the dust-containing gas enters the bag dust collector, large particles and high specific gravity dust settle due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

[0003] After a period of operation, the existing bag dust collector can shake off the dust adsorbed on the dust bag by means of vibration or manually pull out the dust bag for cleaning. However, the above methods are relatively cumbersome and cannot complete the cleaning of the dust bag conveniently and quickly. Utility Model Content

[0030] A plurality of blowing pipes 112 extend from the gas tank 106, each of which is equipped with a blowing solenoid valve 113, and a plurality of connecting pipes 114 are installed on the blowing pipes 112. A mounting plate 108 is fixedly installed in the machine body 101, and a plurality of openings are opened on the mounting plate 108, and a plurality of mounting rings 110 are installed in each opening.

[0031] A dust bag 200 is installed in the mounting ring 110, and the connecting pipe 114 is arranged correspondingly to the dust bag 200.

The filter bag 202 is sleeved on the frame 201 and the mounting pipe 210. A plurality of mounting seats 203 are fixedly installed in the frame 201. Each mounting seat 203 is installed with a plurality of rotating rings 204. A plurality of blades 205 are installed on the rotating ring 204. The minimum distance between the blades 205 on two adjacent rotating rings 204 should be greater than 4 cm to keep the gas unobstructed. In this embodiment, the number of blades 205 on each rotating ring 204 is three, and other numbers can also be selected.

[0032] A plurality of slots 212 are provided on the mounting tube 210, and the number of the slots 212 is the same as that of the rotating ring 204 and they are arranged in one-to-one correspondence.

A channel 209 is provided in the connecting seat 208, and a blowing nozzle 211 is installed at the lower end of the channel 209. Each connecting tube 114 is connected with the corresponding channel 209. When in use, the connecting tube 114 should be inserted into the corresponding channel 209 and sealed by a sealing ring at one end of the connecting tube 114, so that when the air pump 105 is in operation and the pulse solenoid valve 107 and the blowing solenoid valve 113 are opened, the gas blown is ejected through the blowing nozzle 211, and the direction of the gas blown out by the blowing nozzle 211 should be tangent to the concentric circle of the rotating ring 204 to ensure that the rotating ring 204 rotates when the blowing nozzle 211 blows.

[0033] A cavity 111 is provided in the mounting ring 110, and the cross section of the cavity 111 is in a "concave" shape. The mounting ring 110 with the cavity 111 can absorb the shaking force generated by the dust bag 200 during spraying.

Teflon fabric is also sewn on the position where the filter bag 202 can be struck by the striking balls 207, thereby reducing the damage to the filter bag 202 caused by the striking and improving the service life of the filter bag 202.

[0035] A guide plate 115 is installed inside the body 101, and the guide plate 115 extends to the inside of the ash hopper 102. An air inlet 116 is installed on one side of the body 101, and an air outlet 117 is installed on the other side of the body 101. The air inlet 116 is located below the mounting plate 108, and the air outlet 117 is located above the mounting plate 108.
