Abstract
Description
Technical Field
[0001] This utility model relates to the field of antistatic filter bags, and in particular to an antistatic filter bag support. Background Technology
[0002] Antistatic filter bag supports are brackets that secure antistatic filter bags when they are installed inside a filtration device. They are an indispensable accessory for the use of antistatic filter bags.
[0003] However, when using antistatic filter bag support components, the installation position and angle of existing supports cannot be adjusted according to the site space conditions. In narrow or non-standard installation environments, filter bags are prone to local twisting and deformation due to positional deviations, which aggravates the friction on the filter bag surface and causes the risk of static electricity accumulation. At the same time, the support lacks an active expansion mechanism, and the filter bags are prone to collapse and sticking during long-term use. The collapsed area not only hinders the uniform distribution of airflow, but also generates high-potential static electricity due to repeated friction of the filter bag folds, increasing the risk of dust explosion. In addition, most existing supports are designed with a fixed height and cannot be adapted to filter bags of different sizes. When changing the filter bag specifications, the entire support needs to be replaced or auxiliary components need to be added, which leads to increased maintenance costs and decreased installation reliability. Utility Model Content
[0004] The main objective of this invention is to provide an antistatic filter bag support, which can effectively solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An antistatic filter bag support includes a fixed mounting plate, mounting ears, and a support ring. Two fixed mounting plates are included. The mounting ears are integrally formed at the front end of the fixed mounting plate. The support ring is located between the two mounting ears. An adjustment mounting knob is threaded onto one side of each mounting ear. A connecting mounting block is movably mounted on the end of the adjustment mounting knob. A torsion spring shaft is movably mounted on the lower end of the connecting mounting block. An extension mounting rod is fixedly mounted on the outer side of the torsion spring shaft. A lifting mounting structure is movably mounted on the outer side of the extension mounting rod.
[0007] As a further embodiment of this utility model, a locking knob is fitted on the outside of the screw of the adjustment and mounting knob, and the locking knob rests on one side of the connecting mounting block.
[0008] As a further embodiment of this utility model, the bracket ring is fixedly installed between two connecting mounting blocks, and the connecting mounting blocks rotate around the end of the adjusting mounting knob.
[0009] As a further embodiment of this utility model, the torsion spring shaft drives the extension mounting rod to rotate to one side, and the torsion directions of the torsion spring shafts on both sides are opposite.
[0010] As a further embodiment of this utility model, the lifting and mounting structure includes a lifting collar, a positioning knob, a filter bag mounting plate, a retaining ring plate, and a filter bag retaining ring. The lifting collar is movably sleeved on the outside of the extension mounting rod. The positioning knob is threaded onto one side of the lifting collar. The filter bag mounting plate is fixedly mounted on the other side of the lifting collar. Two retaining ring plates are fixedly mounted on the front and rear ends of the filter bag mounting plate. The filter bag retaining ring is movably mounted on the inside of the retaining ring plate.
[0011] As a further embodiment of this utility model, the end of the positioning knob is inserted into the lifting collar and rests on the outside of the extension mounting rod, the filter bag retaining ring passes through the inside of the retaining ring plate, and the filter bag mounting plates on the left and right sides are symmetrically arranged.
[0012] Compared with the prior art, the present invention has the following beneficial effects: by adjusting the cooperation of the installation knob and the locking knob, the connecting installation block can be rotated around the end of the adjustment installation knob, thereby adjusting the left and right position and the use angle of the bracket ring, so that the bracket can quickly adapt to different installation spaces, avoid filter bag deformation or static electricity accumulation caused by position deviation, and make it more convenient to use in narrow or non-standard environments, thereby improving installation efficiency and safety.
[0013] This invention utilizes the elasticity design of a torsion spring shaft to drive the extension mounting rod to rotate to one side, generating an expansion force. The automatic opening mechanism ensures that the filter bag does not collapse during use, reducing the generation of frictional static electricity. After the filter bag is installed, it expands outward to maintain a stable airflow distribution and reduce the risk of electrostatic discharge. At the same time, through the setting of the lifting mounting structure, the lifting collar slides along the extension mounting rod, and the position is tightened by the positioning knob. The height of the filter bag mounting plate can be freely adjusted according to the size of the filter bag to ensure a tight fit, improve versatility and maintenance convenience.

[0021] Please refer to this carefully. Figure 1 and Figure 2 A locking knob 6 is installed on the outside of the screw of the adjusting installation knob 3, and the locking knob 6 is pressed against one side of the connecting installation block 4.
[0022] Please refer to this carefully. Figure 1 and Figure 2 The bracket ring 5 is fixedly installed between two connecting mounting blocks 4, and the connecting mounting blocks 4 rotate around the end of the adjusting mounting knob 3.
[0023] Specifically, the connecting mounting block 4 can be rotated around the end of the adjusting mounting knob 3 to adjust the usage angle of the bracket ring 5. Then, tightening the locking knob 6 positions the connecting mounting block 4 and the bracket ring 5. The adjusting mounting knobs 3 on both sides can be rotated and moved around the mounting ear 2 to adjust the left and right usage position of the bracket ring 5, so that the filter bag can be inserted and installed in different positions and angles.
[0024] Please refer to this carefully. Figure 2 and Figure 3 The torsion spring shaft 7 drives the extension mounting rod 8 to rotate to one side, and the torsion directions of the torsion spring shafts 7 on both sides are opposite.
[0025] Specifically, the elastic force of the torsion spring inside the torsion spring shaft 7 is used to drive the extension mounting rod 8 to rotate to one side, thereby keeping the extension mounting rods 8 on both sides in an expanded state.
[0026] Please refer to this carefully. Figure 3 and Figure 4 The lifting and mounting structure 9 includes a lifting collar 10, a positioning knob 11, a filter bag mounting plate 12, a retaining ring plate 13, and a filter bag retaining ring 14.

The filter bag retaining ring 14 is movably installed on the inside of the retaining ring plate 13.
[0027] Please refer to this carefully. Figure 3 and Figure 4 The end of the positioning knob 11 is inserted into the lifting collar 10 and rests on the outside of the extension mounting rod 8. The filter bag retaining ring 14 passes through the inside of the retaining ring plate 13. The filter bag mounting plates 12 on the left and right sides are arranged symmetrically.
[0028] Specifically, the cone head of the filter bag retainer 14 passes through the bottom of the filter bag, connecting the filter bag to the filter bag mounting plate 12. Then, the filter bag is opened by the expansion of the two side extension mounting rods 8, so that the filter bag is always kept in the open state. The working height of the filter bag retainer 14 can also be adjusted by the lifting collar 10 around the extension mounting rods 8 to accommodate filter bags of different sizes.
