Description

Technical Field

[0001] This utility model relates to the field of filter bag support frame technology, specifically a filter bag support frame. Background Technology

[0002] Filter bags are a crucial component in the operation of baghouse dust collectors. Typically, cylindrical filter bags are suspended vertically within the dust collector. The fabric and design of the filter bags should prioritize high-efficiency filtration, easy dust removal, and durability. During installation, the filter bags are supported by brackets to prevent deformation during use and improve their stability.

[0003] Chinese patent document CN205850449U discloses an adjustable filter bag support frame, which includes a first frame, a second frame and a third frame arranged coaxially. The second frame has openings at both ends. The first frame has an opening at one end that is movably connected to the second frame. One end of the third frame passes through the second frame and abuts against the other end of the first frame. The other end of the third frame protrudes from the second frame.

[0004] Although the overall length of the support frame can be adjusted by coordinating the first, second, and third frames in the above scheme, the different diameters of the first, second, and third frames result in different supporting forces on the filter bags, affecting the stability of the filter bags. In addition, the support frame in the above scheme is rigidly fixed and cannot be adjusted when installing the filter bags, resulting in less shaking force when cleaning the filter bags, making it difficult to shake off the dust adhering to the filter bags. Utility Model Content

[0005] The purpose of this invention is to provide a filter bag support frame to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A filter bag support frame includes multiple assembleable cage frames. A connecting and locking structure is provided between two adjacent cage frames. Each cage frame includes a top frame and a bottom frame. A connecting frame is telescopically provided between the top frame and the bottom frame. The connecting frame includes a fixed frame connected to the top frame at its top. A telescopic groove is provided at the bottom end of the fixed frame. A sliding frame is slidably disposed in the telescopic groove. The bottom end of the sliding frame is connected and fixed to the bottom frame. A telescopic spring is provided between the sliding frame and the inner top wall of the telescopic groove. The connecting and locking structure includes a locking pin rotatably hinged to the top frame. A locking groove is provided on the bottom frame to cooperate with the locking pin. A locking nut is threaded onto the top end of the locking pin.

[0008] As a further embodiment of this utility model: a sealing head is provided at the bottom end of the cage frame, and the sealing head is threadedly connected to the corresponding base frame, thereby achieving sealing at the bottom end of the cage frame.

[0009] As a further embodiment of this utility model: the sealing head includes a sealing base plate, a connecting section is provided on the sealing base plate, the connecting section is threadedly connected to the base frame, and a guide head is provided at the top of the connecting section. The sealing base plate achieves the sealing of the bottom of the cage frame. The connecting section facilitates the detachable connection between the sealing base plate and the base frame, and the guide head provides a guiding function during installation.

[0010] As a further improvement of this utility model, each of the top frames is provided with multiple positioning grooves evenly distributed to facilitate the positioning of external filter bags during installation.

[0011] As a further improvement of this utility model, two limiting protrusions are provided on the outer side of each locking groove. The distance between the two limiting protrusions is greater than the diameter of the locking pin and less than the diameter of the locking nut. The limiting protrusions can restrict the locking nut from moving outward, thereby improving the connection stability between the upper and lower cage frames.

[0012] As a further improvement of this utility model, each of the base frames is provided with a positioning protrusion at its bottom end. The positioning protrusion matches the positioning groove. The cooperation between the positioning protrusion and the positioning groove enables the upper and lower cage frames to be quickly and accurately connected, improving the ease of installation.

[0013] As a further improvement of this utility model, the sealing base plate is provided with an anti-slip twisting groove, which facilitates the twisting of the sealing base plate and improves the anti-slip performance during twisting.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. This utility model includes a multi-section assembleable cage frame, and a connecting and locking structure is provided between two adjacent cage frames. The support frame can be extended as needed by splicing, which improves the convenience of use. The connecting and locking structure can realize the quick docking and installation between two adjacent cage frames, which is convenient to use.

[0016] 2. Each cage frame in this utility model includes a top frame and a bottom frame, and a connecting frame is provided between the top frame and the bottom frame. The connecting frame includes a fixed frame and a sliding frame, and a support spring is provided between the fixed frame and the sliding frame. Through the cooperation of the support spring, the fixed frame and the sliding frame, the cage frame as a whole can follow the external ventilation vibration, thereby vibrating the filter bag fixed on the cage frame, improving the cleaning effect of the filter bag and improving the filtration performance.

[0017] 3. The connecting locking structure of this utility model includes a locking column that is rotatably hinged to the top frame, a locking groove that is provided on the base frame, and a locking nut at the top of the locking column. The locking column, locking groove and locking nut work together to lock and fix the top frame and the corresponding base frame. By rotatably hinged to the top frame, the locking column is prevented from being lost. Furthermore, it is not necessary to completely unscrew the locking nut when locking and fixing or disassembling, thus improving the convenience of use. Attached Figure Description
