Description

Technical Field

[0001] This utility model relates to the field of filter element installation and disassembly technology, and in particular to an air purification filter element for industrial dust collectors. Background Technology

[0002] Currently, industrial dust collectors are widely used as important environmental protection equipment in industrial production processes to capture and filter dust and particulate matter generated during production, in order to improve the quality of the working environment, protect workers' health, and reduce environmental pollution. However, the performance of industrial dust collectors largely depends on the quality and stability of their internal air purification filter elements.

[0003] Traditional industrial dust collector air purification filters often present numerous inconveniences during installation and replacement. On the one hand, the installation structure of some filters is quite complex, requiring tools to tighten bolts and screws, which increases the time cost of installation and replacement. For example, in some industrial scenarios where filter replacement is frequently required, the complex installation process can significantly reduce work efficiency, increase downtime, and thus affect production progress.

[0004] To address these issues, we propose an air purification filter for industrial dust collectors that allows for filter installation and removal without the need for tools. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing an air purification filter element for industrial dust collectors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An air purification filter element for an industrial dust collector includes: a filter element cartridge, a docking ring fixedly connected to the port of the filter element cartridge, a filter element inserted into the filter element cartridge and the docking ring, and connecting components symmetrically arranged on both sides of the docking ring; it also includes a top cover, the top cover snapped onto the port of the docking ring, an inner ring fixedly connected inside the top cover, a support ring arranged on the outer side of the inner ring and fixedly connected inside the top cover, and mounting mechanisms symmetrically arranged on both sides of the support ring and the inner ring, the mounting mechanisms and the connecting components being mutually compatible, which can securely lock the top cover components to the port position of the filter element cartridge.

[0007] Preferably, the connecting assembly includes symmetrically formed grooves on opposite sides of the top of the docking ring, rotating grooves formed in the same direction at the bottom of both sets of grooves, and through grooves formed on the sidewalls of both sets of rotating grooves. Both sets of through grooves penetrate the sidewalls of the docking ring and dock with the installation mechanism.

[0008] Preferably, the installation mechanism includes limiting grooves opened in the middle of both sides of the support ring, abutments slidably installed in both sets of limiting grooves, two sets of limiting posts provided at one end of each set of abutments, and a first spring sleeved on the outside of each set of limiting posts. The multiple sets of limiting posts are slidably connected to limiting holes opened on the inner ring. The two sides of each set of first springs are respectively fixedly connected to the inner ring and the side wall of the abutment, so that the top cover can be locked at the filter cartridge port.

[0009] Preferably, both sets of abutment blocks have rounded corners on their outer sides, and the direction of the rounded corners corresponds to the direction of rotation of the two sets of rotating grooves, making it convenient for the operator to rotate the top cover.

[0010] Preferably, both sets of abutment blocks are fixedly connected to a stop block on their inner side, and the other side of the stop block is fixedly connected to two adjacent sets of limiting posts. The cross-sectional area of ​​the stop block is larger than the cross-sectional area of ​​the limiting groove, so as to limit the abutment block.

[0011] Preferably, an outer cover is fixedly connected to the outside of the top cover, and the inner wall of the outer cover is inserted into the outer side of the docking ring. After the outer cover is inserted into the outer side of the docking ring, the through grooves on both sides of the docking ring are distributed inside the outer cover, which increases the stability of the top cover and the filter cartridge after installation.

[0013] Preferably, a cover is provided at one end of the inner ring and the support ring, and a protruding ring is fixedly connected to the side wall of the cover. The protruding ring is inserted into the cavity between the inner ring and the support ring, which can seal the cavity between the inner ring and the support ring.

[0014] Preferably, a support ring is fixedly connected to one side of the inner wall of the docking ring. After the top cover is inserted into the top of the filter cartridge, the side wall of the cover fits against the top of the bracket, which can support the cover.

Detailed Implementation

[0018] 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.

[0019] Reference Figure 1-5 An air purification filter element for an industrial dust collector includes: a filter element cylinder 1, with a docking ring 11 fixedly connected to the port of the filter element cylinder 1, and a filter element inserted into the filter element cylinder 1 and the docking ring 11, with connecting components symmetrically arranged on both sides of the docking ring 11; it also includes a top cover 2, which is snapped onto the port of the docking ring 11, with an inner ring 21 fixedly connected inside the top cover 2, and a support ring 22 arranged on the outer side of the inner ring 21 and fixedly connected inside the top cover 2, with mounting mechanisms symmetrically arranged on both sides of the support ring 22 and the inner ring 21, the mounting mechanisms and the connecting components being mutually compatible, so as to securely lock the top cover 2 components to the port position of the filter element cylinder 1.

[0020] The filter cartridge 1 and the docking ring 11 have reserved space for installing the filter cartridge. The filter cartridge can be installed into the filter cartridge 1 and the docking ring 11 through a simple plug-in operation. When the filter cartridge reaches the end of its service life or needs to be cleaned and replaced, the old filter cartridge can be pulled out directly and a new filter cartridge can be inserted. The operation is convenient and quick, and easy to maintain.

[0021] When installing the top cover 2, snap the top cover 2 onto the port of the docking ring 11 so that the installation mechanism and the connecting component cooperate to securely lock the top cover 2 component to the port position of the filter cartridge 1. This ensures the structural stability of the filter cartridge during use and prevents dust leakage due to loosening of the top cover 2, which would affect the air purification effect and the working reliability of the industrial dust collector.

[0022] During assembly, the equipment can complete the installation and removal of the filter element without the aid of tools, and without tightening bolts and screws, and stably and securely install the top cover 2 on the port of the filter element cylinder 1.

[0023] Furthermore, the connecting components include symmetrically arranged push grooves 12 on opposite sides of the top of the docking ring 11, rotating grooves 13 in the same direction at the bottom of both push grooves 12, and through grooves 14 on the side walls of both rotating grooves 13. Both through grooves 14 penetrate the side walls of the docking ring 11 and dock with the installation mechanism.

[0024] When installing the top cover 2, first place the top cover 2 initially at the port of the docking ring 11 so that the relevant parts correspond to the push groove 12. Then, by pressing, the structure of the top cover 2 is inserted into the push groove 12. Next, a rotation operation is performed so that the relevant parts of the top cover 2 rotate along the rotating groove 13. After the top cover 2 is rotated into place, the initial connection and positioning of the top cover 2 and the docking ring 11 are achieved. The symmetrical design ensures the balance of forces during connection, improving the balance and stability of the connection.

[0025] Furthermore, the installation mechanism includes limiting grooves 23 opened in the middle of both sides of the support ring 22, abutments 24 slidably installed in both sets of limiting grooves 23, two sets of limiting posts 25 provided at one end of each set of abutments 24, and a first spring 26 sleeved on the outside of each set of limiting posts 25. The multiple sets of limiting posts 25 are slidably connected to the limiting holes opened on the inner ring 21. The two sides of each set of first springs 26 are fixedly connected to the side walls of the inner ring 21 and the abutments 24, respectively, so that the top cover 2 can be locked at the port of the filter cartridge 1.

[0026] During the installation of the top cover 2, when the top cover 2 engages with the docking ring 11, the abutment 24 is subjected to the force of the connecting component and slides within the limiting groove 23, while the limiting post 25 slides within the limiting hole. The first spring 26 is compressed or stretched. After the top cover 2 is installed in place, the elastic force of the first spring 26 causes the abutment 24 to fit tightly with the connecting component, providing a buffer and automatic reset function, ensuring a tight and stable connection between the top cover 2 and the docking ring 11. When disassembling the top cover 2, an opposite force is applied, and the elastic force of the first spring 26 assists the abutment 24 in sliding, allowing the top cover 2 to be separated relatively easily.

[0027] Furthermore, both sets of abutment blocks 24 have rounded corners on their outer sides, and the direction of the two sets of rounded corners corresponds to the direction of rotation of the two sets of rotating grooves 13, making it convenient for the operator to rotate the top cover 2.

[0028] When the top cover 2 is installed and rotated, the abutment 24 needs to enter the rotating groove 13. The rounded corner design makes the contact surface between the abutment 24 and the rotating groove 13 smooth, reducing the resistance during installation and avoiding jamming caused by sharp transitions such as right angles.

[0029] Furthermore, both sets of abutment blocks 24 are fixedly connected to the inner side of a stop block 27, and the other side of the stop block 27 is fixedly connected to the two adjacent sets of limiting posts 25. The cross-sectional area of ​​the stop block 27 is larger than the cross-sectional area of ​​the limiting groove 23, which can limit the abutment block 24.

[0030] During the sliding process of the abutment 24 within the limiting groove 23, the stop block 27 acts as a blocking force. Since the cross-sectional area of ​​the stop block 27 is larger than that of the limiting groove 23, when the abutment 24 slides to a certain position, the stop block 27 will contact the edge of the limiting groove 23 or other related structures, preventing the abutment 24 from continuing to slide outward. This effectively prevents the abutment 24 from sliding out of the limiting groove 23, ensuring the integrity and stability of the installation mechanism and ensuring that the abutment 24 slides within the normal working range.

[0031] Furthermore, an outer cover 33 is fixedly connected to the outside of the top cover 2. The inner wall of the outer cover 33 is inserted into the outer side of the docking ring 11. After the outer cover 33 is inserted into the outer side of the docking ring 11, the through grooves 14 on both sides of the docking ring 11 are distributed inside the outer cover 33, which increases the stability of the top cover 2 and the filter cartridge 1 after installation.

[0032] After the top cover 2 is installed, the outer cover 33 is tightly inserted into the mating ring 11, which increases the sealing of the connection between the top cover 2 and the mating ring 11, forming a sealing barrier to prevent dust from leaking to the outside from the connection part. The outer cover 33 hides the through groove 14 inside, preventing external debris from entering the through groove 14 and preventing debris from affecting the normal operation of the connection components.

[0033] Furthermore, piston holes 3 are provided on both sides of the outer cover 33. Pins 31 are slidably installed in both sets of piston holes 3. Second springs 32 are sleeved on the outer side of both sets of pins 31. The two sets of second springs 32 are fixedly connected to the pins 31 and the side wall of the outer cover 33, respectively. The two sets of pins 31 correspond to the two sets of abutments 24, respectively, and can compress the two sets of abutments 24.

[0034] After the top cover 2 is installed in place, the pin 31 moves towards the abutment block 24 under the elastic force of the second spring 32 and contacts the abutment block 24, providing additional fixing and limiting function for the abutment block 24. When the industrial dust collector is working, vibration may occur. Under the action of the second spring 32, the pin 31 can buffer the impact of vibration on the abutment block 24 and prevent the abutment block 24 from loosening due to vibration, thereby further enhancing the connection stability between the top cover 2 and the docking ring 11 and improving the stability and reliability of the industrial dust collector.

[0035] Furthermore, a cover 34 is provided at one end of the inner ring 21 and the support ring 22. A protruding ring 35 is fixedly connected to the side wall of the cover 34. The protruding ring 35 is inserted into the cavity between the inner ring 21 and the support ring 22, which can seal the cavity between the inner ring 21 and the support ring 22.

[0036] After the top cover 2 is installed, the cover 34 is fixed to one end of the inner ring 21 and the support ring 22 by the insertion and engagement of the convex ring 35 with the cavity between the inner ring 21 and the support ring 22. The cover 34 covers the relevant internal structure of the top cover 2, forming a sealed barrier to prevent dust from entering the interior of the top cover 2.

[0037] Furthermore, a support ring 15 is fixedly connected to one side of the inner wall of the docking ring 11. After the top cover 2 is inserted into the top of the filter cartridge 1, the side wall of the cover 34 fits against the top of the bracket, which can support the cover 34.

[0038] Once the top cover 2 is installed in place, the side wall of the cover 34 fits against the top of the bracket, and the support ring 15 provides a supporting plane for the cover 34, which supports and positions the cover 34 to ensure that the cover 34 is installed in the correct position.

[0039] 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.
