Description

Technical Field

[0001] The utility model belongs to the field of filter bags, and particularly relates to a self-unclogging high-fiber filter bag. Background Technique

[0002] The fiberglass dust removal filter bag is a filtering material made by compound needle punching of fiberglass and a certain proportion of high-temperature-resistant fiberglass. The fiberglass needle felt filter bag is a filtering material with reasonable structure and good performance. This filter bag not only has the advantages of high temperature resistance, corrosion resistance, stable size, extremely small elongation and shrinkage rate, and high strength of fiberglass fabric, but also the fibers in the felt layer are single fibers with a three-dimensional microporous structure and a high porosity. Compared with other high-temperature-resistant chemical fiber felt filter bags, it has special advantages such as low price and higher temperature resistance, but its operating resistance is higher than that of general chemical fiber high-temperature filter materials.

[0003] The Chinese patent with the publication number "CN113856352A" discloses "a self-unclogging high-fiber filter bag". By suspending a plurality of uniformly distributed unclogging balls on the inner surface, relying on the airflow after the air source enters the bag body, it "collides" with the inner surface of the bag body, thereby oscillating and unclogging the blocked area. In addition, the main balls on the surface of the unclogging balls can not only initially filter larger dust, but also trigger a scraping action after contacting the bag body, effectively cleaning the blockage and timely brushing off the adhered dust, thereby effectively restoring the filtering performance of the bag body. Compared with the existing fiber filter bags, it realizes self-unclogging of the blocked area of the bag body by controlling the inlet rate of the airflow.

[0004] Although the filter bag can be unclogged by the unclogging balls to achieve an effective self-unclogging filter bag, the supporting effect of the bag is not good, and the bag cannot be effectively supported and fixed. If the bag is pressed by the outside world, it will collapse, so that the bag cannot play an effective role in filtering and unclogging. Workers also need to take out the bag and restore it again, which will increase the trouble and the workload of the staff, and also reduce the applicability of the filter bag. Summary of the Utility Model

[0005] Aiming at the problems mentioned in the background technique, the purpose of the present utility model is to provide a self-unclogging high-fiber filter bag to solve the problems of the filter bag.

[0008] As a preferred technical solution, four connecting rods are fixedly installed on the inner side of the fixing ring. The end of the connecting rod away from the fixing ring is fixedly installed at the upper end of the cylindrical rod.

[0009] As a preferred technical solution, a circular opening is opened inside the upper end of the cylindrical rod. The screw rod is threadedly connected to the moving column installed inside the cylindrical rod through the circular opening.

[0010] As a preferred technical solution, a handle is fixedly installed at the upper end of the rotating plate. The screw rod rotates through the handle to make the screw rod rotate inside the moving column.

[0011] As a preferred technical solution, a notch is opened inside the cylindrical rod. The screw rod and the moving column are both movably installed inside the notch provided inside the cylindrical rod.

[0012] As a preferred technical solution, an installation block is fixedly installed at one end of the cross bar. A steel wire rope is fixedly installed at one end of the installation block. The end of the steel wire rope away from the installation block is fixedly installed at the upper end of the moving column.

[0013] As a preferred technical solution, a rotating block is fixedly installed at the upper end of the connection port. The cross bar is rotatably installed at the end of the rotating block away from the connection port.

In this way, the steel wire rope installed at the upper end of the moving column will pull the cross plate, causing the cross plate to expand the support plate outward. In this way, the filter cloth bag body will be propped up, effectively supporting and fixing the cloth bag body, providing an effective filtering function for the filter cloth bag, and improving the stability of the cloth bag body;

[0017] Second, since a plurality of dredging balls are installed on the surface of the installation strip, relying on the airflow effect after the air source enters the cloth bag, it can impact the surface of the cloth bag, thereby oscillating and dredging the blocked area, effectively achieving the self-dredging effect, improving the cleaning effect of the cloth bag body. The fixing ring installed at the upper end of the cloth bag body can support the cylindrical rod, enabling the cylindrical rod to hang at the upper end of the cloth bag body, so that the support rod will not fall off.

A plurality of installation strips 5 are fixedly installed on the outer circle of the surface of the cloth bag body 1. A plurality of dredging balls 17 are installed on the surface of the installation strip 5.

[0025] Reference Figures 2 to 3 , Four connecting rods 9 are fixedly installed on the inner side of the fixing ring 8. The end of the connecting rod 9 away from the fixing ring 8 is fixedly installed at the upper end of the cylindrical rod 6. In this way, the cylindrical rod 6 will have a supporting effect, so that the cylindrical rod 6 is hung at the upper end of the cloth bag body 1. In this way, the supporting rod 4 will not fall off, and the cylindrical rod 6 can be effectively limited. A handle 2 is fixedly installed at the upper end of the rotating plate 10. The screw rod 14 is rotated through the handle 2 so that the screw rod 14 rotates inside the moving column 15. A circular opening 12 is opened inside the upper end of the cylindrical rod 6. The screw rod 14 is threadedly connected to the moving column 15 installed inside the cylindrical rod 6 through the circular opening 12. In this way, the handle 2 can be rotated to achieve the rotating effect of the screw rod 14. Then the moving column can move up and down to drive the cross plate to move. In this way, the supporting rod 4 can achieve an effective expansion effect, and then the cloth bag can be supported. A notch 16 is opened inside the cylindrical rod 6. The screw rod 14 and the moving column 15 are both movably installed inside the notch 16 provided inside the cylindrical rod 6.

The surface of the fixing block 20 is fixedly connected with a wire rope 18. The end of the wire rope 18 far from the fixing block 20 is fixedly installed with a dredging ball 17. The dredging ball 17 can rely on the air flow after the air source enters the cloth bag, so that it impacts the surface of the cloth bag, thereby performing shock dredging on the blocked area and effectively achieving the effect of self-dredging, improving the cleaning effect of the cloth bag.

[0027] Principle and advantages of use: When in use, first put the four support rods 4 into the cloth bag, and then rotate the handle 2 installed at the upper end of the rotating plate 10, so that the screw rod 14 fixedly installed at the bottom of the rotating plate 10 rotates. In this way, the moving column 15 threadedly connected to the bottom of the screw rod 14 can achieve the effect of moving. The fixing ring 8 installed at the upper end of the cloth bag body 1 can support the cylindrical rod 6, so that the cylindrical rod 6 is hung at the upper end of the cloth bag body 1. In this way, the support rod 4 will not fall off, and the cylindrical rod 6 can be effectively limited. One end of the cross bar 3 is fixedly installed with a mounting block 13, one end of the mounting block 13 is fixedly installed with a steel wire rope 19, and the end of the steel wire rope 19 far from the mounting block 13 is fixedly installed at the upper end of the moving column 15. Since one end of the steel wire rope 19 is installed at the upper end of the moving column 15, when the moving column 15 moves, it will pull the steel wire rope 19 and cause the cross plate to tilt up. In this way, the support plate installed at one end of the cross plate will support the cloth bag body 1, which can effectively play a role in support and fixation, can effectively support and fix the cloth bag, can provide an effective filtering function for the filter cloth bag, and improve the stability of the filter cloth bag. Since a plurality of dredging balls 17 are installed on the surface of the installation strip 5, they can rely on the air flow after the air source enters the cloth bag, so that they impact the surface of the cloth bag, thereby performing shock dredging on the blocked area and effectively achieving the effect of self-dredging, improving the cleaning effect of the cloth bag.
