Description

Technical Field

[0001] This utility model relates to the field of filter bag technology, specifically to an environmentally friendly filter bag that is easy to connect. Background Technology

[0002] Environmental protection has become a crucial aspect of industrial development, and the investment in environmental protection equipment will account for a large proportion, putting significant financial pressure on users. The core component of a baghouse dust collector is the dust collection filter bag.

[0003] According to the publication number (CN216935101U), a high-temperature resistant and non-deformable environmentally friendly filter bag is disclosed, including a filter bag body. The outer wall surface of the filter bag body is surrounded by a skirt. Multiple skirts are provided and are evenly spaced on the outer wall surface of the filter bag body. A connecting rope is fixed to one side of the skirt, and the end of the connecting rope is fixedly connected to a suspension ring on the top surface of the filter bag body.

[0004] The technical solution has at least the following drawbacks: While this invention can improve the service life of environmentally friendly filter bags, it cannot ensure that the filter bag opening fits snugly against the perforated plate after installation, leading to dust leakage. Furthermore, inserting the frame after each filter bag installation is cumbersome and urgently needs improvement. Therefore, we propose an environmentally friendly filter bag that is easy to connect. Utility Model Content

[0005] The purpose of this utility model is to provide an environmentally friendly filter bag that is easy to connect, which solves the problem mentioned in the background art that the filter bag opening cannot be positioned and fitted with the hole of the tube sheet after installation, thus leading to dust leakage, and that inserting the frame after each filter bag installation is too cumbersome.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly filter bag that is easy to connect, comprising a filter bag body, a positioning sleeve sewn onto the upper end of the filter bag body, an inner cavity of the positioning sleeve having a receiving groove, a lead screw disposed in the middle of the inner cavity of the filter bag body, a lead screw sleeve disposed at the lower end of the lead screw, a positioning plate disposed in the inner cavity of the receiving groove, a smooth rod welded to the upper end of the lead screw, a support strip bonded to the inner cavity of the filter bag body, a straight rod disposed between the support strip and the lead screw, and a hinge seat fixedly installed on the outer side of the lead screw sleeve and the inner side of the support strip.

[0007] By adopting the above technical solution, the lead screw and lead screw sleeve can move downwards. During the downward movement of the lead screw sleeve, the reaction force will push the straight rod to rotate, causing the straight rod to rotate on the hinge seat. This will cause the straight rod to rotate from an inclined state to a state perpendicular to the support bar, thereby achieving the effect of pushing and opening the support bar on the filter bag body, and thus achieving the effect of unfolding the filter bag body. This eliminates the trouble of workers inserting the skeleton after each filter bag installation. In addition, during the rotation of the lead screw, the smooth rod on the lead screw will also rotate, pushing the arc plate. This will cause the arc plate to drive the positioning plate to move, and the positioning plate will push the positioning sleeve against the inner wall of the tube sheet hole, thereby reducing dust leakage.

[0008] Optionally, the size of the lead screw is adapted to the size of the lead screw sleeve, and the lead screw and the lead screw sleeve are threaded together.

[0009] By adopting the above technical solution, the straight rod can be driven to rotate through the cooperation of the lead screw and the lead screw sleeve.

[0010] Optionally, the inner side of the positioning plate is provided with an arc-shaped plate, and the arc-shaped plate is in contact with the smooth rod.

[0011] By adopting the above technical solution and setting up a smooth rod, the curved plate can be pushed.

[0012] Optionally, the support bars are configured as four, and the support bars are arranged in a ring.

[0013] By adopting the above technical solution and setting support strips, the filter bag body can be supported.

[0014] Optionally, the size of the positioning plate is adapted to the size of the receiving groove, and the positioning plate is movably connected to the receiving groove.

[0015] By adopting the above technical solution and setting up the receiving slot, the positioning plate can be conveniently stored.

[0016] Optionally, both ends of the straight rod are rotatably connected to corresponding hinge seats.

[0017] By adopting the above technical solution and setting the hinge seat, the straight rod can be rotated easily.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] This technical solution, through the design of a filter bag body, positioning sleeve, lead screw, arc plate, smooth rod, and hinge seat, allows the lead screw, along with the lead screw sleeve, to move downwards. During this downward movement, the sleeve generates a reaction force that pushes the straight rod to rotate, causing it to rotate on the hinge seat. This rotation transforms the straight rod from an inclined state to a state perpendicular to the support strip, thereby pushing and opening the support strip on the filter bag body, ultimately unfolding the filter bag body. This eliminates the need for workers to insert the frame after each filter bag installation. Furthermore, during the lead screw's rotation, the smooth rod on the lead screw also rotates, pushing the arc plate. This, in turn, causes the arc plate to move the positioning plate, pushing the positioning sleeve against the inner wall of the perforated plate, thus reducing dust leakage.

[0025] Please see Figure 1-3This utility model provides a technical solution: an environmentally friendly filter bag that is easy to connect, including a filter bag body 1, a positioning sleeve 11 sewn onto the upper end of the filter bag body 1, an inner cavity of the positioning sleeve 11 having a receiving groove 12, a lead screw 2 disposed in the middle of the inner cavity of the filter bag body 1, a lead screw sleeve 21 disposed at the lower end of the lead screw 2, a positioning plate 22 disposed in the inner cavity of the receiving groove 12, a smooth rod 24 welded to the upper end of the lead screw 2, a support strip 3 bonded to the inner cavity of the filter bag body 1, a straight rod 4 disposed between the support strip 3 and the lead screw 2, and the outer side of the lead screw sleeve 21... A hinge seat 5 is fixedly installed on the inner side of the support bar 3. There are four support bars 3, which are arranged in a ring. The support bars 3 can support the filter bag body 1. The size of the positioning plate 22 is adapted to the size of the receiving groove 12, and the positioning plate 22 is movably connected to the receiving groove 12. The receiving groove 12 facilitates the storage of the positioning plate 22. The two ends of the straight rod 4 are rotatably connected to the corresponding hinge seat 5. The hinge seat 5 facilitates the rotation of the straight rod 4.

[0026] The size of the lead screw 2 is matched with the size of the lead screw sleeve 21, and the lead screw 2 and the lead screw sleeve 21 are threaded together. Through the cooperation between the lead screw 2 and the lead screw sleeve 21, the straight rod 4 can be driven to rotate.

[0027] An arc-shaped plate 23 is provided on the inner side of the positioning plate 22, and the arc-shaped plate 23 is in contact with the smooth rod 24. The arc-shaped plate 23 can be pushed by the smooth rod 24.

[0028] In use, first insert the filter bag body 1 into the installation position, then rotate the screw 2 clockwise. The screw 2, along with the screw sleeve 21, will move downwards. During the downward movement of the screw sleeve 21, the reaction force will push the straight rod 4 to rotate, causing the straight rod 4 to rotate on the hinge seat 5. This will cause the straight rod 4 to rotate from an inclined state to a state perpendicular to the support bar 3, thereby achieving the effect of pushing and opening the support bar 3 on the filter bag body 1, and thus achieving the effect of unfolding the filter bag body 1. This eliminates the trouble of the staff having to insert the frame after each filter bag installation. At the same time, during the rotation of the screw 2, the smooth rod 24 on the screw 2 will also rotate, causing the smooth rod 24 to push the arc plate 23, which in turn causes the arc plate 23 to move the positioning plate 22. This causes the positioning plate 22 to push the positioning sleeve 11 against the inner wall of the tube sheet hole, thereby reducing dust leakage.
