[0028] Example
[0029] like Figures 1-3As shown, the bag filter frame proposed in this application includes a support plate 1 and a support ring 3, wherein the support plate 1 is a circular structure and the support ring 3 is an annular structure. A plurality of support rods 2 are connected between the support plate 1 and the support ring 3, and the support rods 2 are detachably connected between the support plate 1 and the support ring 3. A support rod positioning member 6 for fixing the support rods 2 is provided at the upper end of the support ring 3, and a protective cover 4 is also connected to the upper end of the support ring 3. The protective cover 4 covers the outer end of the support ring 3 to prevent dust from accumulating on the support rod positioning member 6 and affecting subsequent disassembly. The support plate 1 and the support ring 3 are both provided with locking grooves 7 on their near end faces. A pair of positioning rings 8 are fitted on the outer side of several bone rods 2. When the bag is installed, the two positioning rings 8 are respectively inserted into the two locking grooves 7. When the bag is installed, the bag is located inside the two positioning rings 8, and both ends of the bag are connected to protruding edge rings. The protruding edge rings expand outward from the axis and can cover the two locking grooves 7 respectively. When the two positioning rings 8 are screwed into the two locking grooves 7 respectively, they can just fix the two ends of the bag (the protruding edge rings are thin and will not hinder the positioning rings 8 from being screwed into the locking grooves 7). The two positioning rings 8 are respectively threaded into the two locking grooves 7. After the positioning ring 8 is inserted into the locking groove 7, its outer end extends to the outside of the locking groove 7. The side wall of the positioning ring 8 is fixedly connected to a handle 9 for easy rotation of the positioning ring 8.
[0030] Specifically, the upper end of the support plate 1 has several connecting grooves 10, and several reinforcing rods 2 are respectively inserted into the several connecting grooves 10. The inner walls of the several connecting grooves 10 are all threaded, and the bottom end of the reinforcing rods 2 is threaded. The several reinforcing rods 2 are respectively threaded into the several connecting grooves 10, and the several reinforcing rods 2 are all tightened to the upper end of the support plate 1, and the insertion depth of the several reinforcing rods 2 is the same.
[0031] In this application, the rib positioning component 6 includes an annular groove 63 formed on the upper end of the support ring 3. The support ring 3 has several through grooves that communicate with the annular groove 63. The bottom end of each through groove has a limiting groove 61. The upper sidewall of the rib 2 is fixedly fitted with a limiting ring 62. The limiting rings 62 are respectively engaged in the limiting grooves 61 to position the support ring 3 during installation. The upper sidewall of the rib 2 is machined with external threads. The upper end of the rib 2 extends into the annular groove 63 and is threaded with a nut 64. When the nut 64 is tightened, the nut 64 and the upper end of the rib 2 are both located inside the annular groove 63 and will not protrude above the support ring 3. The inner wall of the support ring 3 is machined with internal threads. The protective cover 4 is threadedly connected to the support ring 3. The bottom end of the inner ring of the protective cover 4 is fixedly connected with a flow guide 5, which guides the airflow.
[0032] The working principle of this embodiment is as follows: When installing the frame, several frame rods 2 are screwed into several connecting grooves 10 in sequence. Then, the cloth bag is placed on the outside of the frame rods 2, so that the cloth bag forms a ring-shaped dust collection state. After the cloth bag is placed, two positioning rings 8 are placed on the outside of the cloth bag. Then, the support ring 3 is clamped on the upper end of the frame rods 2, and several limiting rings 62 are respectively located in several limiting grooves 61. Then, the nuts 64 are tightened on the upper end of the frame rods 2. After all the nuts 64 are tightened, the protective cover 4 is placed on the upper end of the support ring 3 (fixed by thread tightening).
[0033] Finally, the two positioning rings 8 are rotated into the two clamping grooves 7 respectively, pressing the two ends of the filter bag into the two clamping grooves 7 to fix the two ends of the filter bag, thus keeping the filter bag stable during dust removal. The frame in this application can fix the two ends of the filter bag during dust removal, with good stability; and the frame is easy to disassemble, making it convenient to clean or replace the filter bag.
[0034] The above specific embodiments are merely preferred embodiments of this application. Based on the technical solutions of this application and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments. The above specific embodiments are merely explanations of this application and are not limitations on this application.
