Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag technology, specifically a dust collector filter bag with a stretching structure. Background Technology

[0002] Dust collector filter bags are the heart of a baghouse dust collector during operation. Typically, cylindrical pulse-jet filter bags are suspended vertically in the dust collector. Dust-laden gas enters the dust collector through the inlet and passes through the guide plate in the ash hopper, where some large dust particles are separated by inertial force and fall directly into the ash hopper.

[0003] In existing technologies, dust collector filter bags are typically inserted into the air outlet holes of the air outlet plate. The filter bag is then secured by an elastic ring inside the outlet hole, and a cage is inserted to complete the installation. However, in actual use, when cleaning dust adhering to the filter bag surface is required, a pulse valve compresses air to create a reverse airflow into the filter bag, facilitating its filtration function. However, the elastic ring's securing effect is not stable enough. With prolonged use, the elastic ring can easily detach from the outlet, causing the filter bag to fall off and resulting in dust leakage. This method has limitations, therefore, a dust collector filter bag with a tension structure is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a dust collector filter bag with a stretching structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust collector filter bag with a stretching structure, comprising a connecting cover and a filter bag, wherein an elastic ring is provided inside the filter bag, a limiting mechanism is provided outside the connecting cover, and a stretching mechanism is provided outside the limiting mechanism.

[0006] Preferably, the limiting mechanism includes a cage frame, which is fixedly installed on the inner wall of the connecting cover. A threaded column is rotatably installed on the outside of the connecting cover. A rotating wheel is fixedly installed at the end of the threaded column away from the connecting cover. A slide is threaded onto the outside of the threaded column. The slide is slidably installed with the connecting cover. A T-shaped block is fixedly installed on the inner wall of the slide. A compression block is fixedly installed at the bottom of the slide to facilitate the compression of the elastic ring, thereby facilitating the limiting of the connecting cover and the filter bag.

[0007] Preferably, a sliding groove is provided inside the connecting cover at the position corresponding to the T-shaped block, and the T-shaped block is slidably installed in the sliding groove to facilitate the smooth movement of the carriage.

[0008] Preferably, the stretching mechanism includes a connecting plate, which is fixedly installed at the bottom of the extrusion block. A connecting cylinder is fixedly installed inside the connecting plate. A sliding plate is slidably installed on the inner wall of the connecting cylinder. A sliding column is fixedly installed on the outer side of the sliding plate. An elastic block is fixedly installed at the end of the sliding column away from the sliding plate. A spring is fixedly installed between the inner side of the sliding plate and the connecting cylinder, which facilitates the stretching of the filter bag and thus increases the filtration efficiency of the filter bag.

[0009] Preferably, a through hole is provided inside the connecting cylinder at a position corresponding to the sliding column, and the sliding column is slidably installed in the through hole to facilitate the movement of the sliding column and the elastic block.

[0010] Compared with the prior art, the present invention provides a dust collector filter bag with a stretching structure, which has the following beneficial effects:

[0011] 1. This dust collector filter bag with a stretching structure, through a limiting mechanism, expands the filter bag during use by covering the elastic ring with a connecting cover, allowing the cage to extend into the filter bag. A tool is used to rotate the rotating wheel, which, with the cooperation of the T-block, facilitates the movement of the slide, allowing the compression block to move towards the elastic ring and compress it. This ensures a tighter fit between the elastic ring and the air outlet, thus securing the filter bag firmly and preventing it from detaching during operation and thus preventing dust leakage.

[0012] 2. The dust collector filter bag with a stretching structure, through the set stretching mechanism, allows the connecting cylinder to move with the extrusion block during use via the set connecting plate, thereby facilitating the contact between the elastic block and the filter bag, thus stretching the filter bag. Under the elastic action of the spring, the elastic block is always in close contact with the filter bag, making it easy to expand the filter bag and increase the filtration efficiency of the filter bag.

[0025] Furthermore, the limiting mechanism 4 includes a cage 401, which is fixedly installed on the inner wall of the connecting cover 1. A threaded post 402 is rotatably installed on the outside of the connecting cover 1. A rotating wheel 403 is fixedly installed at the end of the threaded post 402 away from the connecting cover 1. A slide 404 is threaded on the outside of the threaded post 402. The slide 404 is slidably installed with the connecting cover 1. A T-block 405 is fixedly installed on the inner wall of the slide 404. A compression block 406 is fixedly installed at the bottom of the slide 404 to facilitate the compression of the elastic ring 3, thereby facilitating the limiting of the connecting cover 1 and the filter bag 2.

[0026] Furthermore, a sliding groove is provided inside the connecting cover 1 at the position corresponding to the T-shaped block 405, and the T-shaped block 405 is slidably installed in the sliding groove to facilitate the smooth movement of the slide 404.

[0027] Example 2:

[0028] Please see Figure 5-6 Furthermore, in conjunction with Embodiment 1, the stretching mechanism 5 includes a connecting plate 501, which is fixedly installed at the bottom of the extrusion block 406. A connecting cylinder 502 is fixedly installed inside the connecting plate 501. A sliding plate 503 is slidably installed on the inner wall of the connecting cylinder 502. A sliding column 504 is fixedly installed on the outer side of the sliding plate 503. An elastic block 505 is fixedly installed at the end of the sliding column 504 away from the sliding plate 503. A spring 506 is fixedly installed between the inner side of the sliding plate 503 and the connecting cylinder 502, which facilitates the stretching operation of the filter bag 2 and thus increases the filtration efficiency of the filter bag 2.

[0029] Furthermore, a through hole is provided inside the connecting cylinder 502 at the position corresponding to the sliding column 504, and the sliding column 504 is slidably installed in the through hole, which facilitates the movement of the sliding column 504 and the elastic block 505.

[0030] In actual operation, when this device is used, the filter bag 2 is passed through the air outlet, and the elastic ring 3 is deformed by squeezing it, so that the elastic ring 3 is engaged in the air outlet, thus completing the positioning of the filter bag 2. The cage frame 401 is inserted into the filter bag 2 to open it. The rotating wheel 403 is rotated by using a tool, which causes the slide 404, which is threaded on the outside of the threaded column 402, to move. This causes the squeezing block 406 to move toward the elastic ring 3 and squeeze the elastic ring 3, so that the elastic ring 3 fits tightly with the air outlet. With the movement of the squeezing block 406, the connecting plate 501 moves, so that the elastic block 505 contacts the filter bag 2, and the sliding plate 503 squeezes the spring 506. Under the elastic action of the spring 506, the filter bag 2 is opened, increasing the filtration efficiency.
