Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, and in particular to a leak-proof clamp for filter bags used in dust collectors. Background Technology

[0002] The filter bag chuck for dust collectors is a sealing component installed at the filter bag opening. It secures the filter bag to the dust collector's tube sheet, preventing unfiltered gas from leaking directly from the tube sheet interface. While bolts are typically used for connection, vibrations during operation can cause these bolts to loosen, resulting in insufficient tightening force, poor sealing, and dust leakage. To address this issue, we have proposed a leak-proof chuck for dust collector filter bags. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where dust collectors vibrate, causing bolts to loosen due to vibration, resulting in insufficient bolt tightening force, poor sealing, and dust leakage. This invention provides a leak-proof clamp for filter bags in dust collectors.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A leak-proof chuck for filter bags in a dust collector is designed, comprising a fixing ring with multiple fixing holes evenly spaced around its circumference. A sealing ring is fixedly connected to the upper end of the fixing ring, located inside the circle formed by the multiple fixing holes. A filter bag connecting mechanism is provided on the lower end face of the fixing ring. Limiting blocks are provided at the lower ends of the multiple fixing holes, and the multiple limiting blocks are fixedly connected to the inner ring wall of a rotating ring. The rotating ring is rotatably connected to the fixing ring via a bearing and is positioned by a positioning mechanism.

[0006] Preferably, the sealing ring is a silicone rubber sealing ring.

[0007] Preferably, the filter bag connecting mechanism includes a connecting ring, the connecting ring being fixedly connected to a connecting groove, the connecting ring being fixedly connected to the lower end face of a fixed ring, and the connecting groove being formed on the outer ring wall of the connecting ring.

[0008] Preferably, the bearing is a thrust ball bearing.

[0009] Preferably, the positioning mechanism includes a connecting ear, which is fixedly connected to the rotating ring. A fixing post is provided through the connecting ear, which is inserted into the connecting sleeve. The connecting sleeve is fixedly connected to the lower end face of the fixing ring, and the fixing post is limited by a limiting mechanism.

[0010] Preferably, the retaining ring is made of stainless steel.

[0011] Preferably, the limiting mechanism includes a fixing frame, which is fixedly connected to the connecting ear, and a fastening spring is fixedly connected to the fixing frame, which is fixedly connected to the fixing post.

[0012] Preferably, the fastening spring is in a compressed state, and the fastening spring is a stainless steel spring.

[0013] The present invention proposes a leak-proof chuck for filter bags in dust collectors, which has the following advantages: the use of nuts on the limit block bolts for contact prevents the bolts from loosening due to vibration, thereby ensuring the sealing effect between the sealing ring and the tube sheet and preventing dust leakage. At the same time, the design of the rotating ring allows multiple limit blocks to move together at the same time, which is beneficial for the simultaneous position adjustment of multiple limit blocks.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Refer to Figure 1-5 A leak-proof chuck for a filter bag in a dust collector includes a fixing ring 1. The fixing ring 1 has multiple fixing holes 3 evenly spaced around its circumference. A sealing ring 2 is fixedly connected to the upper end of the fixing ring 1. The sealing ring 2 is located inside the circle formed by the multiple fixing holes 3. The sealing ring 2 protects the bolts and helps prevent dust from getting into the threaded connection of the bolts.

[0022] The retaining ring 1 is made of stainless steel to prevent rust, and it has good rigidity to prevent deformation under load.

[0023] A filter bag connecting mechanism is provided on the lower end face of the fixed ring 1. Each of the lower ends of the multiple fixed holes 3 is provided with a limit block 5. The multiple limit blocks 5 are fixedly connected to the inner ring wall of the rotating ring 4. The rotating ring 4 is rotatably connected to the fixed ring 1 through a bearing. The rotating ring 4 is positioned by a positioning mechanism and connected to the tube sheet by bolts passing through the fixed holes 3. The nuts of the limit block 5 bolts are used for abutment to prevent the bolts from loosening due to vibration, thereby ensuring the sealing effect between the sealing ring 2 and the tube sheet and preventing dust leakage. At the same time, the design of the rotating ring 4 allows multiple limit blocks 5 to move together at the same time, which is conducive to the simultaneous position adjustment of multiple limit blocks 5.

[0024] The sealing ring 2 is a silicone rubber sealing ring. Silicone rubber has good elasticity and sealing properties to ensure the sealing effect of the sealing ring 2.

[0025] Example 2: Refer to Figure 1-3 In another preferred embodiment of this utility model, based on embodiment 1, the filter bag connecting mechanism includes a connecting ring 6, with a connecting groove 7 fixedly connected to it. The connecting ring 6 is fixedly connected to the lower end face of the fixing ring 1. The connecting groove 7 is formed on the outer ring wall of the connecting ring 6, and the connecting groove 7 has an annular structure. The filter bag is wrapped around the connecting ring 6 through the bag opening. The filter bag fibers are melted and fused together with the connecting ring 6 using a hot melt machine. After cooling, the connection is completed. The design of the connecting groove 7 ensures the contact area. The molten filter material fibers flow into the connecting groove 7, and after cooling, they form a retaining ring structure that connects with the connecting groove 7. The connection strength exceeds the planar connection of the filter bag, thereby ensuring the connection effect between the filter bag and the connecting ring 6.

[0026] The bearing is a thrust ball bearing. When the bolts loosen, they will exert a force on the limiting block 5. The force is transmitted to the rotating ring 4, causing the rotating ring 4 to be subjected to axial force. Therefore, the bearing connected to the rotating ring 4 needs to be subjected to axial force load. Thus, a thrust ball bearing capable of axial force load is used.

[0027] Example 3: Reference Figure 1-5In another preferred embodiment of this utility model, based on embodiment 2, the positioning mechanism includes a connecting ear 11, which is fixedly connected to the rotating ring 4. A fixing post 9 is provided through the connecting ear 11, which is inserted into the connecting sleeve 12. The connecting sleeve 12 is fixedly connected to the lower end face of the fixing ring 1. The fixing post 9 is limited by a limiting mechanism. The fixing post 9 and the connecting sleeve 12 play a role in limiting and fixing the position of the rotating ring 4, ensuring that the limiting block 5 can always abut against the nut of the bolt, thus preventing the bolt from loosening.

[0028] The limiting mechanism includes a fixed frame 8, which is fixedly connected to the connecting ear 11. A fastening spring 10 is fixedly connected to the fixed frame 8 and is fixedly connected to the fixed post 9. The fastening spring 10 is in a compressed state and is a stainless steel spring. By using the restoring force of the fastening spring 10, the fixed post 9 is firmly inserted into the connecting sleeve 12, preventing the fixed post 9 from coming off the connecting sleeve 12 during use.

[0029] When connecting the chuck, firstly, the fixing post 9 is pulled out of the connecting sleeve 12 to release the fixing of the rotating ring 4. Then, the rotating ring 4 is rotated, which drives the limiting block 5 to rotate, causing the limiting block 5 to shift out of the fixing hole 3. A bolt is inserted into the fixing hole 3. After the bolt is tightened, the rotating ring 4 is rotated, which drives the limiting block 5 to rotate. When the limiting block 5 abuts against the nut of the bolt, the bolt is limited to prevent it from loosening. By inserting the fixing post 9 into the connecting sleeve 12 to limit and fix the rotating ring 4, the rotating ring 4 is prevented from rotating, ensuring the abutting effect between the limiting block 5 and the nut, and avoiding the situation where the bolt loosens due to vibration caused by the operation of the dust collector.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
