Description

Technical Field

[0001] The utility model relates to the technical field of filter bag frames, in particular to an environmentally friendly filter bag pleated frame. Background Art

[0002] Environmentally friendly filter bags are a key part of the operation of bag dust collectors. They have excellent chemical stability and heat resistance. They are the highest performance representatives used in the filter material industry and the highest-end performance varieties among all commonly used filter materials. They have achieved high levels in terms of filtration efficiency and filtration accuracy. Environmentally friendly filter bags are usually used in conjunction with support frames. The pleated frames are used in conjunction with corrugated pleated filter bags to increase the filtration area of ​​the filter bags and reduce the filtration wind speed. A type of environmentally friendly filter bag pleated frame is now commonly used.

[0003] The pleated frame of the environmentally friendly filter bag in the existing technology is usually an integrated structure with a fixed length specification. Since the specifications of environmentally friendly filter bags and bag dust collectors are relatively diverse, environmentally friendly filter bag pleated frames of different specifications and lengths need to be used in actual dust removal work. A pleated frame of one specification and length can only be used for environmentally friendly filter bags of corresponding specifications, which has poor practicality and a narrow scope of application. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an environmentally friendly filter bag pleated frame.

[0005] The top end of each fixing rod is fixed with the top frame and the bottom frame, and the fixing rod has a fixing structure which is fixed to the top frame and the bottom frame.

[0006] By adopting the above technical solution, when it is necessary to adjust the length of the frame, the staff pulls the plug rod outward through the control block and limits the control block through the limit assembly, so that the plug rod is disengaged from the plug-in state with the fixed groove, thereby moving the adjustment rod downward to an appropriate height, and then releasing the limiting effect of the limit assembly on the control block. Under the action of the elastic force of the spring, the control block inserts the plug rod into the fixed groove to fix the adjustment rod, which is convenient for adjusting the length of the frame according to environmentally friendly filter bags of different specifications, thereby improving the practicality of the pleated frame.

[0007] Furthermore, the limiting assembly includes a mounting block fixed to the side wall of the control block, the side wall of the mounting block is provided with a receiving groove, and the limiting assembly also includes a rotating shaft rotatably connected to the inner wall of the receiving groove and a support rod fixedly sleeved on the rotating shaft.

[0008] By adopting the above technical solution, when the length of the frame needs to be adjusted, the staff pulls the control block and then rotates the support rod to a state perpendicular to the fixed rod, so that the end of the support rod abuts against the side wall of the fixed rod, thereby limiting the control block and keeping the control block in the pulled-out state, which is convenient for adjusting the height of the adjustment rod.

[0009] Furthermore, a torsion spring sleeved on the rotating shaft is provided in the accommodating groove, one end of the torsion spring is fixed to the inner wall of the accommodating groove, and the other end of the torsion spring is fixed to the side wall of the support rod.

[0010] By adopting the above technical solution and setting the torsion spring, the support rod automatically opens under the torsion force of the torsion spring after the staff pulls out the control block, eliminating the tedious operation of the staff to manually open the support rod, and facilitating the rapid limitation of the control block.

[0011] Furthermore, a rubber pad is fixed to the end of the support rod.

[0012] By adopting the above technical solution, the rubber pad is made of rubber material, and its surface has a large friction coefficient. The rubber pad increases the friction between the end of the support rod and the side wall of the fixed rod, and reduces the probability of the support rod displacing on the side wall of the fixed rod.

[0013] Furthermore, a limiting groove is provided on the inner wall of the adjusting groove, and a limiting block is fixed on the side wall of the adjusting rod and is slidably connected to the limiting groove.

[0014] By adopting the above technical solution, the limit block is slidably connected in the limit groove, which limits the moving position of the adjustment rod and prevents the adjustment rod from falling out of the adjustment groove, which is conducive to the normal use of the frame.

[0015] Furthermore, one end of the insertion rod away from the control block is chamfered.

[0016] By adopting the above technical solution and setting the chamfer, the difficulty of aligning the insertion rod with the fixing groove is reduced, making it easier to align and plug the insertion rod with the fixing groove.

[0017] Furthermore, a reinforcing plate is fixedly sleeved on the outer walls of the plurality of adjusting rods.

[0018] By adopting the above technical solution, the reinforcing plate connects the multiple adjustment rods, making it easy to adjust the length of the skeleton by pulling the multiple adjustment rods at the same time.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. In this application, when the length of the frame needs to be adjusted, the staff pulls the plug rod outward through the control block and limits the control block through the limit assembly, so that the plug rod is disengaged from the plug-in state of the fixed groove, thereby moving the adjustment rod downward to a suitable height, and then releasing the limiting effect of the limit assembly on the control block. Under the elastic force of the spring, the control block inserts the plug rod into the fixed groove to fix the adjustment rod, making it easy to adjust the length of the frame according to environmentally friendly filter bags of different specifications, thereby improving the practicality of the pleated frame;

[0021] 2. In this application, when the length of the frame needs to be adjusted, the staff pulls the control block and then rotates the support rod to a position perpendicular to the fixed rod, so that the end of the support rod abuts against the side wall of the fixed rod, thereby limiting the control block and keeping the control block in the pulled-out state, making it easier to adjust the height of the adjustment rod;

[0022] 3. In this application, the setting of the torsion spring enables the support rod to automatically open under the torsion force of the torsion spring after the staff pulls out the control block, eliminating the tedious operation of the staff to manually open the support rod, and facilitating the rapid limitation of the control block.

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] like Figure 1-4 As shown, an embodiment of the present application discloses an environmentally friendly filter bag pleated frame, including a top frame 1, a bottom frame 2, a fixing rod 3, an adjusting rod 4, a fixing assembly 5 and a limiting assembly 6.

[0030] The top frame 1 and the bottom frame 2 are both annular plate-like structures, with the bottom frame 2 disposed below the top frame 1. The fixing rod 3 is a vertically arranged round rod-like structure fixed to the bottom of the top frame 1. There are multiple fixing rods 3 evenly distributed about the axis of the top frame 1. Each fixing rod 3 has an adjustment slot 31 at its bottom, and each fixing rod 3 has a mounting slot 32 on its sidewall. The adjusting rod 4 is a vertically arranged round rod-like structure. There are multiple adjusting rods 4, each of which is slidably connected to the inner walls of the multiple adjusting slots 31. The lower end of each adjusting rod 4 is fixed to the upper surface of the bottom frame 2, and each adjusting rod 4 has multiple fixing slots 41 on its sidewall.

[0031] Multiple sets of fixing assemblies 5 are provided, each mounted on a plurality of fixing rods 3 to secure the adjustment rod 4. Each set of fixing assemblies 5 includes an insert rod 51, a control block 52, and a spring 53. The insert rod 51 is a horizontally arranged rectangular rod-like structure that extends through the side wall of the fixing rod 3 and is slidably connected thereto. The insert rod 51 engages with the fixing slot 41. The control block 52 is a rectangular parallelepiped structure that is fixed to the end of the insert rod 51 away from the adjustment rod 4. The spring 53 is disposed within the mounting slot 32, with one end of the spring 53 secured to the side wall of the control block 52 and the other end secured to the inner wall of the mounting slot 32.

[0032] The position-limiting assembly 6 is mounted on the control block 52 and functions to limit the position of the control block 52. The position-limiting assembly 6 comprises a mounting block 61, a rotating shaft 62, and a support rod 63. The mounting block 61 is a rectangular parallelepiped structure fixed to the side wall of the control block 52. A receiving slot 611 is defined in the side wall of the mounting block 61. The rotating shaft 62 is a round rod-shaped structure, rotatably connected to the inner wall of the receiving slot 611. The support rod 63 is a rectangular rod-shaped structure, fixedly mounted on the rotating shaft 62.

[0033] When the length of the frame needs to be adjusted, the staff pulls the insertion rod 51 outward through the control block 52 and rotates the support rod 63 to a state perpendicular to the fixed rod 3, so that the end of the support rod 63 abuts against the side wall of the fixed rod 3, thereby limiting the control block 52, so that the control block 52 remains in the pulled-out state, and the insertion rod 51 is disengaged from the plug-in state with the fixed groove 41, thereby moving the adjustment rod 4 downward to an appropriate height, and then rotating the support rod 63 to make the support rod 63 parallel to the control block 52, releasing the limiting effect of the limit assembly 6 on the control block 52, and under the elastic force of the spring 53, the control block 52 causes the insertion rod 51 to be inserted into the fixed groove 41 to fix the adjustment rod 4, so that the length of the frame can be adjusted according to environmentally friendly filter bags of different specifications, thereby improving the practicality of the pleated frame.

[0034] In order to facilitate the rapid limiting of the control block 52, a torsion spring 7 is provided in the accommodating groove 611 and is sleeved on the rotating shaft 62. One end of the torsion spring 7 is fixed to the inner wall of the accommodating groove 611, and the other end of the torsion spring 7 is fixed to the side wall of the support rod 63. The setting of the torsion spring 7 enables the support rod 63 to automatically open under the torsion force of the torsion spring 7 after the staff pulls out the control block 52, eliminating the tedious operation of the staff to manually open the support rod 63, thereby facilitating the rapid limiting of the control block 52.

[0035] In order to reduce the probability of the support rod 63 being displaced on the side wall of the fixed rod 3, a rubber pad 8 is fixed to the end of the support rod 63. The rubber pad 8 is made of rubber material and its surface has a large friction coefficient. The rubber pad 8 increases the friction between the end of the support rod 63 and the side wall of the fixed rod 3, thereby reducing the probability of the support rod 63 being displaced on the side wall of the fixed rod 3.

[0036] In order to prevent the adjusting rod 4 from falling off the adjusting slot 31 downward, a limiting slot 33 is provided on the inner wall of the adjusting slot 31, and a limiting block 9 is fixed to the side wall of the adjusting rod 4 which is slidingly connected to the limiting slot 33. The limiting block 9 is slidingly connected in the limiting slot 33, which limits the moving position of the adjusting rod 4, thereby preventing the adjusting rod 4 from falling off the adjusting slot 31 downward, which is beneficial to the normal use of the skeleton.

[0037] In order to facilitate the alignment and insertion of the insertion rod 51 with the fixing groove 41, a chamfer 511 is provided at the end of the insertion rod 51 away from the control block 52. The setting of the chamfer 511 reduces the difficulty of aligning the insertion rod 51 with the fixing groove 41, thereby facilitating the alignment and insertion of the insertion rod 51 with the fixing groove 41.

[0038] In order to facilitate pulling multiple adjustment rods 4 at the same time, a reinforcing plate 10 is fixedly sleeved on the outer walls of the multiple adjustment rods 4. The reinforcing plate 10 connects the multiple adjustment rods 4, so as to facilitate pulling multiple adjustment rods 4 at the same time to adjust the frame length.

[0039] The operating principle of an environmentally friendly filter bag pleated frame in this embodiment is as follows: when the length of the frame needs to be adjusted, the staff pulls the insertion rod 51 outward through the control block 52 and rotates the support rod 63 to open the state perpendicular to the fixed rod 3, so that the end of the support rod 63 abuts the side wall of the fixed rod 3, thereby limiting the control block 52, so that the control block 52 remains in the pulled-out state, and the insertion rod 51 is disengaged from the plug-in state with the fixed groove 41, thereby moving the adjustment rod 4 downward to an appropriate height, and then rotating the support rod 63 to make the support rod 63 parallel to the control block 52, releasing the limiting effect of the limit assembly 6 on the control block 52, and the control block 52, under the elastic force of the spring 53, causes the insertion rod 51 to be inserted into the fixed groove 41 to fix the adjustment rod 4, so that the length of the frame can be adjusted according to environmentally friendly filter bags of different specifications, thereby improving the practicality of the pleated frame.
