Description

Technical Field

[0001] This utility model relates to the field of pleated filter bag technology, specifically a pleated filter bag for dust removal modification of blast furnace feeding system. Background Technology

[0002] Dust collector filter bags are the heart of baghouse dust collectors, generally referred to as dust collector bags or dust filter bags. They are a crucial component in the operation of baghouse dust collectors, typically suspended vertically within the collector. Pleated filter bags are a type of dust collector filter bag, with pleats on the outside to increase the filtration area. Blast furnace feeding systems generate dust during material feeding, necessitating the use of pleated filter bags for dust removal.

[0003] Existing pleated filter bags are mostly directly fitted onto the frame. After long-term operation of the dust collection device, the pleated filter bag is prone to shaking on the frame or even falling off, thus affecting the normal dust removal effect of the pleated filter bag. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a pleated filter bag for dust removal retrofitting of blast furnace feeding systems. It has the advantage of easy fixation and solves the problem that existing pleated filter bags are mostly directly fitted onto the frame, which are prone to shaking after long-term operation or even falling off the frame, thus affecting the normal dust removal effect of the pleated filter bag.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pleated filter bag for dust removal retrofitting of a blast furnace feeding system, comprising a main component, wherein the main component includes:

[0008] The pleated filter bag body has an external skeleton.

[0009] The pleated filter bag body and the frame are provided with a fixing component, the fixing component including:

[0010] A connecting ring is fixedly connected to the top of the pleated filter bag body;

[0011] The connecting block is fixedly connected to the bottom of the connecting ring;

[0012] The outer frame is fixedly connected to the outer wall of the skeleton;

[0013] A cavity is formed within the outer frame;

[0014] Spring one is symmetrically and fixedly connected to the left side wall of the cavity;

[0015] A crossbar is slidably connected to the inner wall of the cavity, and the left side of the crossbar is fixedly connected to the spring.

[0016] The tie rod has one end fixedly connected to the left side wall of the crossbar, and the other end extends through and out of the outer frame.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, this utility model provides a pleated filter bag for dust removal retrofitting of a blast furnace feeding system, which has the following beneficial effects:

[0024] This pleated filter bag offers the advantage of easy fixation. The pleated filter bag body is inserted into the frame, and the connecting ring is fitted onto the top of the frame. The connecting block at the bottom of the connecting ring is inserted into the cavity. When the inclined surface at the bottom of the connecting block contacts the crossbar, it pushes the crossbar to the left, facilitating the connecting block's deeper penetration into the cavity. At this point, spring one is compressed. When the groove on the connecting block moves to the same horizontal line as the crossbar, spring one pushes the crossbar into the groove of the connecting block, achieving automatic fixation of the connecting block. This completes the connection between the frame and the pleated filter bag body, preventing the pleated filter bag body from detaching from the frame after long-term use. This solves the problem that existing pleated filter bags, which are often directly fitted onto the frame, are prone to shaking or even detaching from the frame after long-term operation, thus affecting the normal dust removal effect of the pleated filter bag.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] See Figure 1-5 A pleated filter bag for dust removal retrofitting of a blast furnace feeding system includes a main component 1, comprising: a pleated filter bag body 11 with an external frame 12; fixing components 2 on the pleated filter bag body 11 and the frame 12, the fixing components 2 including: a connecting ring 21 fixedly connected to the top of the pleated filter bag body 11; a connecting block 22 fixedly connected to the bottom of the connecting ring 21; an outer frame 23 fixedly connected to the outer wall of the frame 12; a cavity 231 opened within the outer frame 23; a spring 24 symmetrically and fixedly connected to the left side wall of the cavity 231; a crossbar 25 slidably connected to the inner side wall of the cavity 231, the left side of the crossbar 25 being fixedly connected to the spring 24; and a pull rod 26, one end fixedly connected to the left side wall of the crossbar 25, the other end penetrating and extending to the outside of the outer frame 23. Multiple sets of fixing components 2, except for the connecting ring 21, are symmetrically arranged, with at least two sets. A second spring 271 is fixedly connected to the bottom surface of the cavity 231, and a spring plate 27 is fixedly connected to the top of the second spring 271. The outer wall of the spring plate 27 is slidably connected to the inner wall of the cavity 231.

[0036] During use, the operator inserts the pleated filter bag body 11 into the frame 12 and places the connecting ring 21 on top of the frame 12. The connecting block 22 at the bottom of the connecting ring 21 is inserted into the cavity 231. When the inclined surface at the bottom of the connecting block 22 contacts the crossbar 25, it pushes the crossbar 25 to the left, making it easier for the connecting block 22 to penetrate deeper into the cavity 231. At this time, the spring 24 is compressed. When the groove on the connecting block 22 moves to the same horizontal line as the crossbar 25, the spring 24 pushes the crossbar 25 into the groove of the connecting block 22, thereby automatically fixing the connecting block 22 and completing the connection between the frame 12 and the pleated filter bag body 11, preventing the pleated filter bag body 11 from falling off the frame 12 after long-term use. When it is necessary to remove the pleated filter bag body 11, the operator pulls the lever 26 outwards. The lever 26 causes the crossbar 25 to disengage from the groove of the connecting block 22. At this time, the connecting ring 21 is lifted, which allows the pleated filter bag body 11 to be removed from the frame 12, facilitating the replacement of the pleated filter bag body 11. The bottom of the connecting ring 21 has multiple connecting blocks 22 that connect to the frame 12, thereby increasing the firmness of the connection between the pleated filter bag body 11 and the frame 12. When the connecting block 22 is inserted into the cavity 231, the bottom end of the connecting block 22 pushes the spring plate 27 down, and the spring 271 is compressed. When the operator pulls the lever 26 to release the restriction on the connecting block 22, the compressed and deformed spring 271 pushes the spring plate 27 upwards, and the spring plate 27 pushes the connecting block 22 upwards, thus making it easy for the operator to remove the connecting ring 21 from the frame 12.

[0037] Example 2

[0038] An auxiliary function has been added based on Embodiment 1.

[0039] See Figure 1-5 The distance between the inner and outer rings of the connecting ring 21 is equal to the diameter difference of the skeleton 12. The outer wall of the connecting ring 21 is fixedly connected with anti-slip texture 211. The inner wall of the cavity 231 is symmetrically provided with sliding grooves 251, and both ends of the crossbar 25 extend into the sliding grooves 251, and both ends of the crossbar 25 are slidably connected to the sliding grooves 251.

[0040] The distance between the inner and outer rings of the connecting ring 21 is equal to the diameter difference of the frame 12, ensuring that the connecting ring 21 cannot wobble on top of the frame 12 when placed on top, thus increasing the stability of the pleated filter bag body 11 after connection with the frame 12. The anti-slip texture 211 on the outside of the connecting ring 21 increases the friction between the worker's hand and the connecting ring 21, making it easier to remove the connecting ring 21 from the frame 12 in a timely manner. When the crossbar 25 moves left and right under the influence of the connecting block 22 and the spring 24, both ends of the crossbar 25 slide within the slide groove 251. The slide groove 251 guides the movement of the crossbar 25, preventing it from tilting when squeezed, thus facilitating timely and precise positioning of the connecting block 22 by the crossbar 25.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
