[0029] Please refer to Figures 1 to 3The present application provides a bag filter, including a container 10, an impurity cleaning assembly 70, a filter bag 90 and a cleaning assembly 80. The upper and lower parts of the container 10 are respectively provided with an inlet pipe 20 and an outlet pipe 30 connected to the accommodating space of the container, and the top of the container 10 is provided with a take-in and put-out port, and the take-in and put-out port is covered with a sealing cover 40; the impurity cleaning assembly 70 includes a power member 72, a rotating shaft 73 and a rotating frame 71 rotatably arranged inside the container 10, the power member 72 is installed at the bottom of the container 10, one end of the rotating shaft 73 extends to the rotating frame 71 and is connected to the bottom end of the rotating frame 71, and the rotating shaft 73 is away from one end of the rotating frame 71. The end extends out of the container 10 and is connected to the output end of the power member 72; the filter bag 90 is detachably mounted on the periphery of the rotating frame 71, and after the filter bag 90 is loaded into the rotating frame 71, the inner surface of the filter bag 90 contacts the outer surface of the rotating frame 71; the cleaning assembly 80 includes a cleaning pipe 81 arranged in the container 10 and a plurality of nozzles 82 connected to the cleaning pipe 81, the cleaning pipe 81 is arranged in the container 10 along the height direction of the container 10 and is located on the outside of the rotating frame 71, and the water inlet of the cleaning pipe 81 extends out of the container 10 and is connected to an external water source, and the nozzle 82 is used to spray the cleaning liquid input into the cleaning pipe 81 toward the rotating frame 71.

[0030] For example, the power member 72 can be a rotating motor, which drives the rotating frame 71 to rotate. Since the outer surface of the rotating frame 71 contacts the inner wall of the filter bag 90, the inner wall of the filter bag 90 is scraped off, so that the impurity particles attached to the inner wall of the filter bag fall off, so that the impurity particles filtered out of the filter bag 90 can be cleaned conveniently and quickly, and the operator is no longer required to disassemble and replace the filter bag 90. The operation is simple, time-saving, labor-saving, and easy to use, which greatly reduces the labor intensity of the operator. The above power member 72 using a rotating motor is only an example, but not limited to this.

[0031] For example, the container 10 is made of aluminum alloy so that the container 10 has sufficient compressive strength to avoid deformation due to external extrusion, which may result in failure of normal filtration. The aluminum alloy material may also have a certain degree of corrosion resistance.

[0032] The bag filter based on the above technical features is provided with a rotatable rotating frame 71 inside the container 10, and the filter bag 90 is sleeved on the outer periphery of the rotating frame 71. At this time, the inner wall of the filter bag 90 is in contact with the outer surface of the rotating frame 71. When the filtering efficiency of the filter bag 90 is reduced, the power member 72 is used to drive the rotating frame 71 to rotate so that the foreign matter particles attached to the inner wall of the filter bag 90 can fall off, so that the foreign matter particles filtered out of the filter bag 90 can be cleaned conveniently and quickly, and the operator is no longer required to disassemble and replace the filter bag 90. The operation is simple, time-saving, labor-saving, and easy to use, which greatly reduces the labor intensity of the operator. In addition, a cleaning pipe 81 is provided on the outer periphery of the rotating frame 71, and a plurality of nozzles 82 are provided on the cleaning pipe 81, so that the cleaning liquid can be sprayed onto the filter bag 90, and the rotation of the rotating frame 71 is coordinated to further clean the foreign matter particles on the filter bag 90.

[0033] In a possible embodiment, a coupling 74 is further included, one end of which is connected to the end of the rotating shaft 73 extending outside the container 10, and the other end of the coupling 74 is connected to the output end of the power member 72. In this way, the rotating shaft 73 is connected to the output end of the power member 72 by the coupling 74, so that the power member 72 can drive the rotating frame 71 connected to the rotating shaft 73 to rotate; when the power member 72 or the rotating frame 71 needs to be replaced, the coupling 74 is disassembled to separate the rotating shaft 73 from the output end of the power member 72, thereby realizing the disassembly of the power member 72 or the rotating frame 71, which has a simple structure and is easy to disassemble and assemble.

[0034] In a possible embodiment, the rotating frame 71 includes a fixed ring 712, a fixed plate 713 and a plurality of vertical bars 711, wherein the plurality of vertical bars 711 are arranged in sequence in a ring shape, the fixed ring 712 and the fixed plate 713 are respectively disposed at both ends of the vertical bar 711, one end of the vertical bar 711 extending toward the loading and unloading port is fixedly connected to the fixed ring 712, the other end of the vertical bar 711 is fixedly connected to the fixed plate 713, the fixed plate 713 is connected to the upper end of the filter bag 90 and the fixed ring 712, and the end of the rotating shaft 73 extending into the container 10 is connected to the fixed plate 713.

[0035] Exemplarily, the two ends of the vertical bar 711 are respectively connected to the fixed ring 712 and the fixed plate 713 to assemble into a rotating frame 71. Since the multiple vertical bars 711 are arranged in a ring-shaped interval so that there are gaps between the vertical bars 711, when the power member 72 drives the rotating shaft 73 to rotate, the fixed plate 713 is driven to rotate, and then the vertical bars 711 connected to the fixed plate 713 are driven to rotate, so as to scrape the inner wall of the filter bag 90, thereby quickly removing foreign particles attached to the inner wall of the filter bag 90.

[0036] In a possible embodiment, the inner side of the fixing ring 712 is provided with a plurality of hooks 712a in an annular shape, the hooks 712a are bent toward the direction of the access port, and the upper end of the filter bag 90 extends outward with a plurality of fasteners 90a for hooking with the hooks 712a. In this way, when the filtering efficiency of the filter bag 90 is low and the filtering efficiency cannot be restored by the rotation of the rotating frame 71, the filter bag 90 needs to be replaced. At this time, it is only necessary to open the sealing cover 40, and then separate the fastener 90a of the filter bag 90 from the hook 712a, and then pull the filter bag 90 downward to quickly remove the filter bag 90; when the filter bag 90 is installed with the rotating frame 71, the top of the filter bag 90 is inserted from the bottom of the rotating frame 71, and the filter bag 90 is lifted upward so that the rotating frame 71 is stored in the filter bag 90, and finally the fastener 90a is hooked with the hook 712a, so as to realize the installation of the filter bag 90, with a simple structure and convenient disassembly and assembly.

[0037] In a possible embodiment, a locking assembly 50 is further included, and the locking assembly 50 includes a locking ring 51 and a locking block 52, one end of the locking block 52 is movably connected to one end of the locking ring 51, and a sliding groove is provided on the locking block 52. When the locking block 52 is pushed close to the locking ring 51, the other end of the locking ring 51 is inserted into the sliding groove and slides, so that the locking ring 51 is tightened to fix the sealing cover 40 on the container 10.

[0038] In a possible embodiment, a support frame 60 is further included, and the support frame 60 includes a collar 62 and a plurality of support legs 61, the collar 62 is sleeved on the lower part of the container 10, and the plurality of support legs 61 are distributed in an annular shape outside the collar 62, and the upper ends of the support legs 61 are fixedly connected to the outer surface of the collar 62. In this way, the collar 62 is sleeved into the lower part of the container 10 in a sleeved manner to achieve rapid disassembly of the support frame 60, with a simple structure and convenient disassembly and assembly.

[0039] In a possible implementation, the lower end of the support leg 61 is bent in a direction perpendicular to the support leg 61 to form a bent portion 611, and a fixing hole 611a for fixing to the ground is provided on the bent portion 611. In this way, a fastener is passed through the fixing hole 611a and inserted into the ground, thereby achieving a fastened connection between the support leg 61 and the ground, and preventing random movement during use.

[0040] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope covered by the claims of the utility model.
