Abstract
Description
Technical Field
[0001] This utility model belongs to the field of filtration equipment, and specifically relates to a filter cartridge installation structure for a dust collector. Background Technology
[0002] In existing dust collection equipment, filter cartridges are generally cylindrical and installed into the dust collector's mounting holes. During operation, due to the lack of a fixed reference point, the rotation of the filter cartridge is unrestricted. Prolonged pulse backflushing and vibration can cause the filter cartridge to shift or rotate, affecting not only the sealing performance and reducing dust collection efficiency, but also accelerating wear on the filter cartridge and mounting components, ultimately leading to premature failure of the filter cartridge or related parts. Furthermore, some dust collector mounting holes are irregularly shaped (such as triangular ones), which can only accommodate custom-made filter cartridges and cannot be matched with traditional cylindrical filter cartridges, resulting in poor applicability. Therefore, there is an urgent need for a filter cartridge mounting structure that is universally compatible with various dust collector mounting holes and can also provide good positioning for cylindrical filter cartridges, improving performance. Utility Model Content
[0003] To overcome the shortcomings and problems of the existing technology, this utility model provides a filter cartridge installation structure for a dust collector, which can play a good positioning role for cylindrical filter cartridges and is suitable for irregularly shaped dust collector installation holes, with good adaptability.
[0004] This utility model is achieved through the following technical solution:
[0005] A filter cartridge mounting structure for a dust collector includes a fixed base located inside a dust collector mounting hole. A guide tube and a support frame are connected to the fixed base. The support frame passes through the guide tube and extends to the inlet of the dust collector mounting hole. The support frame is provided with a support rod for supporting the inner hole of the filter cartridge. A connecting rod is provided at the end of the support frame. A pressure cap is provided at the inlet of the dust collector mounting hole. The pressure cap is fixed to the connecting rod. The pressure cap is provided with a protrusion that pushes into the inner ring of the filter cartridge.
[0006] The support frame is provided with no less than two support rods, and the support rods are matched with the slots of the filter cartridge.
[0007] The connecting rod is provided with a threaded section, and the pressure plate is provided with a connecting hole. The threaded section is inserted into the connecting hole, and the threaded section is provided with a bolt head for locking the pressure plate. The bolt head is provided with a triangular lobe.
[0008] The outer ring of the pressure cap is provided with an outer sealing ring, which abuts against the inlet edge of the dust collector mounting hole to form a seal.
[0009] The pressure cap is provided with an inner sealing ring for abutting against the end face of the filter cartridge.
[0010] The clearance between the support rod and the groove of the filter cartridge is ≤3mm.
[0011] The pressure cap is provided with directional markings.
[0012] One end of the guide tube is provided with a flange, which is connected and fixed to the fixed base, and the other end is provided with an annular disc, which matches and abuts against the end face of the filter cartridge for sealing.
[0013] The support frame of this utility model has a support rod, and the inner hole of the cylindrical filter cartridge can be equipped with a groove to match the support rod. During installation, the support rod is inserted into the groove, thereby fixing the cylindrical filter cartridge in place and preventing it from rotating. Even after long-term pulse backflushing and vibration, the filter cartridge will not be misaligned or rotated, ensuring sealing, improving dust removal efficiency, avoiding wear on the filter cartridge and mounting components, and extending the filter cartridge's lifespan. Because of the guide tube and pressure cap, one end of the filter cartridge abuts and seals against the guide tube, and the protrusion of the pressure cap pushes into the inner hole of the other end of the filter cartridge, so that the pressure cap seals against the filter cartridge. The pressure cap also seals against the inlet of the dust collector's mounting hole. The shape of the mounting hole does not affect the seal, and the relevant seals are guaranteed. Therefore, this type of dust collector can be adapted to install cylindrical filter cartridges without affecting the installation of custom-shaped filter cartridges, making it highly applicable.

Detailed Implementation
[0019] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] like Figure 1-4As shown, a filter cartridge mounting structure for a dust collector includes a fixed base 1 located within a mounting hole 71 in the dust collector. The fixed base 1 has an opening 11 for ventilation. A guide tube 2 and a support frame 3 are connected to the fixed base 1, providing support for the guide tube 2 and the support frame 3. One end of the guide tube 2 has a flange 21, which is connected and fixed to the fixed base 1, thus securing the guide tube 2. The other end has an annular disc 22, which matches and seals against the end face of the filter cartridge. During filter cartridge installation, the end face of the filter cartridge abuts against the annular disc 22 to form a seal, allowing the guide tube 2 to communicate with the inner hole of the filter cartridge.
[0021] The support frame 3 passes through the guide tube 2 and extends to the inlet of the dust collector mounting hole 71. The support frame 3 is equipped with support rods 31 for supporting the filter cartridge's inner hole. The filter cartridge 6's inner hole has a slot 61. During installation, the support rods 31 are engaged in the slots 61, thus fixing the filter cartridge 6 and preventing it from rotating. Even prolonged pulse backflushing and vibration will not cause the filter cartridge 6 to shift or rotate, ensuring sealing, improving dust removal efficiency, preventing wear between the filter cartridge 6 and the mounting components, and extending the filter cartridge's lifespan. The support frame 3 has at least two support rods 31, which match the slots 61 of the filter cartridge, making the structure more stable. The clearance between the support rods 31 and the slots of the filter cartridge is ≤3mm, allowing control over the amount of rotation of the filter cartridge during use.
[0022] The support frame 3 has a connecting rod 32 at its end, and a pressure cap 4 is provided at the inlet of the dust collector mounting hole 71. The pressure cap 4 is fixed to the connecting rod 32, facilitating its installation and fixation. The connecting rod 32 has a threaded section, and the pressure cap 4 has a connecting hole 43. The threaded section is inserted into the connecting hole 43, and a bolt head 5 is provided on the threaded section to lock the pressure cap, thereby securing the pressure cap 4. The bolt head 5 has a triangular flap 51 for easy rotation. The pressure cap 4 has a protrusion 41 that pushes into the inner ring of the filter cartridge, making the seal between the pressure cap 4 and the filter cartridge more reliable. The outer ring of the pressure cap 4 has an outer sealing ring 42, which abuts against the inlet edge of the dust collector mounting hole 71 to form a seal. This structure ensures a good seal between the pressure cap 4 and the dust collector mounting hole 71. The pressure cap 4 has a direction mark 44 for easy orientation during installation. The pressure cap 4 is provided with an inner sealing ring 45 for abutting against the end face of the filter cartridge, which further enhances the seal between the pressure cap 4 and the filter cartridge.
[0023] The installation process of this utility model is as follows: First, align the slot 61 of the filter cartridge 6 with the support rod 31, and push the filter cartridge 6 into the mounting hole 71 of the dust collector 7. The support rod 31 is locked in the slot 61. When the filter cartridge 6 is fully pushed in, the end face of the filter cartridge abuts against the annular disc 22 of the guide tube 2, forming a seal, and the airflow in the guide tube 2 can flow into the filter cartridge 6. Align the connecting hole 43 of the pressure cap 4 with the connecting rod 32 and insert it. Tighten the pressure cap 4 with the bolt head 5. The protrusion 41 of the pressure cap 4 abuts against the inner hole of the filter cartridge 6, forming a seal with the filter cartridge. The inner sealing ring 45 abuts against the end face of the filter cartridge, further improving the sealing performance between the pressure cap 4 and the filter cartridge. The outer sealing ring 42 of the pressure cap 4 abuts against the inlet of the dust collector mounting hole 71, forming a seal between the pressure cap 4 and the dust collector mounting hole 71. The pressure cap 4 forms a seal with both the filter cartridge 6 and the dust collector mounting hole 71, thus adapting to different shapes of dust collector mounting holes and filter cartridges.
[0024] The above embodiments are preferred implementations of this utility model and are not intended to limit this utility model. Any obvious substitutions are within the protection scope of this utility model without departing from its inventive concept.
