Description

Technical Field

[0001] This utility model relates to the field of dust collection bag technology, specifically a pneumatic conveying closed-loop dust collection bag. Background Technology

[0002] In the existing technology, when pneumatically conveying powder, a dust collector needs to be installed at the bottom of the silo. When the powder is conveyed, the air and powder enter the silo and generate a lot of dust. The centrifugal fan of the dust collector can then draw the dust into the dust collector, thereby achieving the effect of air-material separation by using the dust collection bags installed inside the dust collector.

[0003] However, when dust-laden gas enters the dust collector under the pull of the fan, large dust particles will directly impact the filter bag when the wind speed is too high, which may cause the filter bag to perforate and affect the dust removal effect. This also leads to a reduction in the service life of the dust collector filter bag. To address this problem, this utility model proposes a pneumatic conveying closed-loop dust collector bag. Utility Model Content

[0004] The purpose of this invention is to provide a pneumatic conveying closed-loop dust collector bag to solve the problems mentioned in the background art.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 7 This utility model provides a technical solution: a pneumatic conveying closed-loop dust collector bag, comprising: a dust collector 1, a feed pipe 10 provided on the side of the dust collector 1, a support plate 2 provided inside the dust collector 1, a through hole opened on the surface of the support plate 2, an installation pipe 3 provided in the through hole, a bag body 4 provided at the bottom of the installation pipe 3, a first bearing 5 provided on the outer surface of the installation pipe 3, a fixing nut 6 provided on the outer ring surface of the first bearing 5, and a threaded tube 7 provided at the bottom of the fixing nut 6; a protective plate 8, and a rubber plate 9 provided on the surface of the protective plate 8;

[0024] When the dust-laden gas is drawn into the dust collector 1 by the fan, the larger particles of dust will first come into contact with the protective plate 8. The surface of the protective plate 8 is provided with a rubber plate 9, which can reduce the noise caused by the impact. The protective plate 8 can also act as a shield, thus preventing large dust particles from directly impacting the surface of the filter bag body 4 when the wind speed is too high, thereby improving the service life of the filter bag body 4.

[0025] Example 2: Based on Example 1, an installation tube 3 is provided to facilitate the installation and fixing of the bag body 4. The protective plate 8 is in the shape of an "L" plate. The rubber plate 9 is fixedly connected to the side of the protective plate 8. The protective plate 8 is located at the end face of the feed pipe 10. The surface of the support plate 2 is provided with a threaded groove 17. The threaded pipe 7 is screwed into the threaded groove 17. A limit plate 18 is provided on the outer side of the installation tube 3. The limit plate 18 is in the shape of an "L" plate. One end of the limit plate 18 is inserted into the positioning slot 11.

[0026] When installing the filter bag body 4, the filter bag body 4 can first be passed through the support plate 2, and then the fixing nut 6 can be rotated in conjunction with the first bearing 5, which will drive the threaded tube 7 to rotate. Then the threaded tube 7 can be screwed into the threaded groove 17, and the filter bag body 4 can be fixedly installed inside the dust collector 1. The protective plate 8 can prevent large dust particles from directly hitting the surface of the filter bag body 4 and causing damage to the filter bag body 4.

[0027] Example 3: Based on Example 2, in order to improve the stability of the installation of the mounting pipe 3, a fixing rod 16 is provided.

A threaded hole is provided on the surface of the lifting plate 15. A fixing rod 16 is screwed into the threaded hole. A limit groove 19 is provided on the surface of the fixing nut 6. The fixing rod 16 is inserted into the limit groove 19.

[0028] When the threaded tube 7 is screwed into the threaded groove 17, the fixing rod 16 can be inserted into the limiting groove 19 to prevent the threaded tube 7 from rotating and causing the installation tube 3 to loosen. The limiting plate 18 can be inserted into the positioning slot 11 to prevent the installation tube 3 from rotating, thereby improving the stability of the fixing rod 16 inserted into the limiting groove 19. In use, the elastic force of the return spring 14 can also be used to prevent the lifting plate 15 from moving randomly.

[0029] In actual use, when the dust-laden gas enters the dust collector 1 under the suction of the fan, the larger particles of dust will first come into contact with the protective plate 8. The surface of the protective plate 8 is provided with a rubber plate 9, which can reduce the noise caused by impact. The protective plate 8 can also act as a shield, thus preventing large dust particles from directly impacting the surface of the filter bag body 4 when the wind speed is too high, thereby improving the service life of the filter bag body 4. When the threaded tube 7 is screwed into the threaded groove 17, the fixing rod 16 can be inserted into the limiting groove 19 to prevent the threaded tube 7 from rotating and causing the installation tube 3 to loosen. The limiting plate 18 is inserted into the positioning slot 11 to prevent the installation tube 3 from rotating, thereby improving the stability of the fixing rod 16 inserted into the limiting groove 19. In use, the elasticity of the return spring 14 can also be used to prevent the lifting plate 15 from shifting randomly.
