[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the utility model provides a technical solution: a bag filter for water treatment, comprising a shell 1, a control box 11 is fixedly connected to the outer side of the upper end of the shell 1, and a water inlet 12 is fixedly connected to the middle end of the upper side of the shell 1, a sleeve 13 is inserted and fixedly connected inside the shell 1, and a bag filter 14 is inserted inside the sleeve 13, a water outlet 15 is fixedly connected to the outer side of the lower end of the shell 1, and the water outlet 15 is inserted at one end of the inner part of the shell 1 and is fixed through the sleeve 13, a sewage outlet 16 is fixedly connected to the lower side of the bag filter 14, and the lower end of the sewage outlet 16 passes through the sleeve 13 and the shell 1, an electric valve 17 is fixedly connected to the outer side of the lower end of the sewage outlet 16, and the outer side of the middle end of the shell 1 A pushing component is fixedly connected, and transmission components are fixedly connected to the outer sides of both ends of the pushing component, and a striking component is fixedly connected to the end of the transmission component away from the pushing component. When cleaning the debris attached to the inner side of the bag filter 14, the pushing component is started, and the driving component is used to drive the transmission component to operate, so that the transmission component drives the striking component to intermittently strike the outer side of the bag filter 14, so that the bag filter 14 vibrates to shake off the debris attached to the inside, so that the bag filter can effectively clean the debris attached to the inner side of the bag filter 14 during use, thereby improving the protection effect of the bag filter 14 and avoiding damage caused by pulling and other factors.

[0024] like Figure 5 As shown, a snap-fit ​​assembly is fixedly connected to the outer side of the upper end of the sleeve 13, and a limiting assembly is fixedly connected to the outer end of the snap-fit ​​assembly. When the bag filter 14 needs to be installed and used, the sleeve 13 and the bag filter 14 are snapped together by the snap-fit ​​assembly, and then the limiting assembly is used to limit the position, so that the installation of the bag filter 14 is simpler and more convenient, and at the same time the stability of the bag filter 14 after installation is indicated.

[0025] like Figure 3 As shown, the pushing assembly includes a shield 2 fixedly connected to the outer side of the middle end of the shell 1, and an electric telescopic rod 21 is fixedly connected to the upper side of the shield 2, and the lower end of the electric telescopic rod 21 passes through the shield 2 and is fixedly connected to a first push plate 22. After the electric telescopic rod 21 is started, the first push plate 22 is driven to move under the limit of the shield 2, so that the first push plate 22 is used to drive the transmission assembly to operate.

[0026] like Figure 4 As shown, the transmission assembly includes a second push plate 3 fixedly connected to the lower side of both ends of the first push plate 22, and the lower side of one end of the second push plate 3 away from the first push plate 22 is rotatably connected to the third push plate 31, and the end of the third push plate 31 away from the second push plate 3 is rotatably connected to the push rod 32. After the first push plate 22 moves, it synchronously pushes the second push plate 3, so that the second push plate 3 pushes the third push plate 31. After the third push plate 31 is pushed, it drives the striking assembly to strike the outer side of the bag filter 14, so as to make the bag filter 14 vibrate.

[0027] like Figure 4 As shown, the striking assembly includes a telescopic device 4 inserted at one end of the push rod 32 away from the third push plate 31. The telescopic device 4 is a prior art structure, also known as a telescopic joint, a telescopic joint or a compensator, and is a flexible component. The outer side of the end of the telescopic device 4 close to the third push plate 31 is fixed in the sleeve 13, and the side of the telescopic device 4 away from the third push plate 31 is fixedly connected with a striking plate 41, and the side of the push rod 32 away from the third push plate 31 is fixedly connected to the striking plate 41. After the first push plate 22 moves, it synchronously pushes the second push plate 3, so that the second push plate 3 pushes the third push plate 31. After the third push plate 31 is pushed, it drives the striking plate 41 to strike the outer side of the bag filter 14 under the telescopic limit of the telescopic device 4, so that the bag filter 14 can vibrate to shake off the debris attached to its inner wall.

[0028] like Figure 5 As shown, the clamping assembly includes a clamping ring 5 fixedly connected to the outer side of the upper end of the sleeve 13, and the outer side of the clamping ring 5 is fitted with a sleeve ring 51, and the lower side of one end of the sleeve ring 51 is fixedly connected to the upper side of the bag filter 14, and the bag filter 14 is pre-installed by using the clamping ring 5 and the sleeve ring 51.

[0029] like Figure 5 As shown, the limiting assembly includes a block 6 inserted inside one end of the ring 51 away from the bag filter 14, and a spring 61 is fixedly connected to the side of the block 6 away from the sleeve 13, the end of the spring 61 away from the block 6 is fixedly connected to the ring 51, and the end of the block 6 away from the spring 61 is inserted on the lower side of the snap ring 5, the spring 61 pushes the block 6 in the reverse direction to make it pop out, so that the block 6 fits on the lower side of the snap ring 5, which is convenient for limiting the ring 51, thereby enhancing the resistance encountered by the ring 51 when being pulled up.

[0030] Working principle: When using a bag filter to filter sewage, first inject the sewage into the bag filter 14 in the housing 1 through the water inlet 12, and then use the bag filter 14 to filter the debris in the sewage. After filtration, the cleaner water is discharged from the water outlet 15, while the debris remains on the inner side of the lower end of the bag filter 14. When it is necessary to clean the debris in the bag filter 14, the control box 11 controls the operation of the electric valve 17 and the electric telescopic rod 21, and the electric valve 17 is opened to allow the sewage to carry the debris and be discharged from the sewage outlet 16. After the electric telescopic rod 21 is started, it pushes the first push plate 22 to move. After the first push plate 22 moves, it simultaneously pushes the second push plate 3, so that the second push plate 3 pushes the third push plate 31. After the third push plate 31 is pushed, it drives the striking plate 41 to hit the outer side of the bag filter 14 under the telescopic limit of the telescopic device 4. The bag filter 14 is then pulled out of the housing 1 and the replaced sleeve 51 is then driven by the bag filter 14 to be inserted into the sleeve 13. During the insertion process, the block 6 is pressed by hand on both sides to allow the block 6 to be inserted into the sleeve 51 and the spring 61 is compressed. After the block 6 is fitted with the sleeve 51, the spring 61 pushes the block 6 in the opposite direction to eject the block 6, thereby allowing the block 6 to fit into the lower side of the sleeve 5.

[0031] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
