Description

Technical Field

[0001] The invention belongs to the technical field of dust collectors, and in particular relates to a dust removal device for a bag type dust collector. Background Art

[0002] Bag filter is a dry dust filter device, which is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter dust-containing gas. When the dust-containing gas enters the bag filter, the dust with large particles and high specific gravity settles down due to gravity and falls 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. A layer of dust accumulates on the surface of the filter bag, which is called the primary layer. In the subsequent movement process, the primary layer becomes the main filtering layer of the filter material. Relying on the effect of the primary layer, the filter material with larger mesh can also obtain higher filtering efficiency. As dust accumulates on the surface of the filter material, the efficiency and resistance of the dust collector increase accordingly. When the pressure difference on both sides of the filter material is large, some fine dust particles attached to the filter material will be squeezed over, causing the dust collector efficiency to decrease. In addition, excessive resistance of the dust collector will significantly reduce the air volume of the dust removal system. Therefore, after the filter resistance reaches a certain value, the dust should be cleaned in time to avoid the efficiency decline.

[0003] The cleaning methods of bag dust collector include mechanical vibration cleaning, backblowing cleaning, gas pulse cleaning and cyclone cleaning. Pulse cleaning is to use high-pressure gas to spray to the filter bag through a nozzle to make the inside of the filter bag pulsate and make the dust on the filter bag fall off. When the high-pressure gas is sprayed out, due to the large temperature difference between the high-pressure gas and the inside of the dust collector, liquefied water is easily formed, causing the dust on the surface of the filter bag to mix with water, resulting in compaction and forming a sticky belt, which is not easy to clean, and the service life of the filter bag is greatly shortened. Compared with the pulse cleaning method, the mechanical vibration cleaning cost is lower, the method is simple, the operation is easy, the damage to the filter bag is less, the service life of the filter bag is longer, but the cleaning effect is lower. Summary of the invention

[0004] In view of the above situation, in order to improve the cleaning effect of the mechanical vibration method, the present invention provides a bag dust collector removal device. Through the proposed self-triggering reciprocating device, the filter bag is periodically and repeatedly deformed and pulled up during the filtering process to achieve the purpose of the vibrating track. In the device of the present invention, the filter bag is deformed by moving the built-in supporting member. Compared with the traditional beating, the fixed support in the device of the present invention directly contacts the filter bag. The filter bag is cleaned by the penetration and pounding of the fixed support on the filter bag, and with the assistance of the self-triggering reciprocating device, the device of the present invention can realize autonomous recovery and penetration, thereby improving the cleaning effect while ensuring minimal damage to the filter bag.

[0031] When in use, the drive motor 30 is turned on, and the drive ring 31 electrically connected to the drive motor 30 rotates, driving the rotating column 23 to rotate. During the rotation of the rotating column 23, the insertion hole 21 of the connecting tube ring 19 is fixedly connected to the insertion inner tube 35, and the tail of the connecting column 33 is squeezed by the special-shaped block 39 to stretch the limit spring 36.

The engaging protrusion 32 moves toward the tail end of the connecting column 33, and the engaging protrusion 32 cannot engage with the spiral texture 24. Under the reset action of the reset spring 9, it rebounds, the sliding plate 7 is reset, and the connecting pipe ring 19 quickly falls back to the initial state. The sliding ring 37 is reset under the reset of the support spring 40, and the retaining ring is also reset. The special-shaped block 39 squeezes the connecting column 33 again, and the engaging protrusion 32 at the front end of the connecting column 33 engages with the spiral texture 24 of the rotating column 23 again. The fixed support 8 is reset in a short time, supports the filter cloth bag 14, and tightens and vibrates the filter cloth bag 14 to make the dust outside the filter cloth bag 14 fall off.

[0032] In actual use, the device of the present invention can be arranged in an array in a bag-type dust collector, and the rotation speed of the rotating column 23 can be controlled by setting the rotation rate of the driving ring 31 in the driving motor 30, so as to achieve real-time cleaning of the filter bag 14 itself while filtering dust in the gas.
