Description

Technical Field

[0001] The utility model relates to the technical field of triple-proof needle-punched felt filter bags, in particular to a triple-proof needle-punched felt filter bag. Background Art

[0002] In the production and use of chemical, metallurgical and mining industries, a large amount of dust is generated. For this reason, needle-punched felt filter bags are needed to filter it. In order to increase the practicality of the filter bags, multiple dust-proof functions are added to the existing needle-punched felt filter bags. For this reason, a three-proof needle-punched felt filter bag is developed, which has waterproof, anti-electrical and oil-proof functions.

[0003] During use, the triple-proof needle-punched felt filter bag needs to be connected to the pipeline. Most of the existing ones use spring belts or drawstrings to fix them, but when there is a size mismatch, the clamping will be unstable. The common drawstring is fixed by manual knotting, which makes it easy to loosen during the knotting process and is inconvenient, making it inconvenient for staff to use. For this reason, we proposed a triple-proof needle-punched felt filter bag. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a triple-proof needle-punched felt filter bag to solve the above problems.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A triple-proof needle-punched felt filter bag comprises a filter bag main body, a circular shell is provided on the outside of the filter bag main body, a circular block is fixedly connected to the bottom of the inner wall of the circular shell, a sliding assembly is provided on the top of the circular block, one side of the inner wall of the circular shell is rotatably connected to a rotating shaft, the other end of the rotating shaft extends to the outside of the circular shell, a transmission assembly is provided on the outside of the rotating shaft, and a movable and fixed assembly is provided inside the circular shell.

[0007] Preferably, the sliding assembly comprises a circular chute provided on the top of the circular block, and a circular sliding block is slidably connected inside the circular chute.

[0008] Preferably, one end of the rotating shaft located outside the circular shell is fixedly connected to a handle, and the handle is made of rubber.

[0009] Preferably, the movable fixing assembly comprises four circumferentially distributed threaded sleeves rotatably connected to the inner wall of the circular shell, and the internal threads of the threaded sleeves are connected to threaded rods.

[0010] Preferably, one end of the threaded rod is fixedly connected to a clamping block, and a sliding groove is provided on the top of the round shell, and the clamping block slides inside the sliding groove.

[0011] Preferably, the transmission assembly includes a first gear fixedly sleeved on the outside of the rotating shaft, a second gear fixedly sleeved on the outside of each of the four threaded sleeves, a circular gear disk fixedly connected to the top of the circular slider, and the first gear, the second gear and the circular gear disk are meshed and connected.

[0012] The invention has the following advantages: when the filter bag body needs to be fixed, the circular shell is first sleeved on the outside of the filter bag body, and then the handle is held and rotated, the rotating shaft and the first gear rotate, driving the circular gear disk to rotate, and the circular gear disk is slidably connected to the inside of the circular slide groove by the circular slider, so that the circular gear disk is more stable when moving. Due to the meshing connection between the circular gear disk and the second gear, the rotation of the circular gear disk can drive the second gear and the threaded sleeve to rotate, and then drive the threaded rod and the clamping block to move inside the sliding groove. At this time, the clamping block can clamp the filter bag body inside the circular shell, and is slidably connected to the inside of the sliding groove by the clamping block, so that the clamping block will not rotate when moving. The above structure is convenient for the staff to fix the filter bag body on the circular shell for installation, avoiding the traditional method of using spring belts or pull ropes to fix them, but when the sizes do not match, the clamping is unstable, and the common pull rope is fixed by manually tying it, which makes it easy to loosen during the knotting process, which greatly facilitates the use of the staff.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example: Refer to Figure 1-3 The top of the circular block 3 is provided with a sliding assembly, which includes a circular slide groove 4 opened at the top of the circular block 3, and a circular slider 5 is slidably connected to the inside of the circular slide groove 4 through the circular slider 5, so that the circular toothed disc 6 is more stable when moving. One side of the inner wall of the circular shell 2 is rotatably connected to the rotating shaft 7, and the other end of the rotating shaft 7 extends to the outside of the circular shell 2. The end of the rotating shaft 7 located on the outside of the circular shell 2 is fixedly connected to a handle 8. The material of the handle 8 is rubber. The rubber handle 8 is provided to improve the comfort of the staff when holding the handle 8.

[0019] Specifically, a transmission assembly is provided on the outside of the rotating shaft 7, and the transmission assembly includes a first gear 9 fixedly sleeved on the outside of the rotating shaft 7, and the outsides of the four threaded sleeves 11 are fixedly sleeved with a second gear 10, and the top of the circular slider 5 is fixedly connected to a circular toothed disk 6, and the first gear 9, the second gear 10 are meshed with the circular toothed disk 6. Through the provided transmission assembly, the four threaded sleeves 11 can rotate simultaneously, and a movable fixed assembly is provided inside the circular shell 2, and the movable fixed assembly includes four circumferentially distributed threaded sleeves 11 rotatably connected to the inner wall of the circular shell 2, and the internal threads of the threaded sleeves 11 are connected to a threaded rod 12. Through the provided movable fixed assembly, the filter bag body 1 can be fixed on the circular shell 2, and one end of the threaded rod 12 is fixedly connected to a clamping block 13, and a sliding groove 14 is provided on the top of the circular shell 2. The clamping block 13 slides inside the sliding groove 14 and is slidably connected to the inside of the sliding groove 14 by the clamping block 13, so that the clamping block 13 does not rotate when it moves.

[0020] During use: when the filter bag body 1 needs to be fixed, first sleeve the circular shell 2 on the outside of the filter bag body 1, then hold the handle 8 and rotate it. By rotating the handle 8, the rotating shaft 7 and the first gear 9 can be driven to rotate. Since the first gear 9 is meshed with the circular toothed disc 6, the circular toothed disc 6 can be driven to rotate by rotating the first gear 9. The circular toothed disc 6 is slidably connected to the inside of the circular slide 4 through the circular slider 5, so that the circular toothed disc 6 is more stable when moving. Since the circular toothed disc 6 is meshed with the second gear 10, the second gear 10 and the threaded sleeve 11 can be driven to rotate by rotating the circular toothed disc 6, and then the circular toothed disc 6 is driven to rotate. The threaded rod 12 and the clamping block 13 move inside the sliding groove 14. At this time, the clamping block 13 can clamp the filter bag body 1 and fix it inside the round shell 2. The clamping block 13 is slidably connected to the inside of the sliding groove 14, so that the clamping block 13 will not rotate when moving. The above structure is convenient for the staff to fix the filter bag body 1 on the round shell 2 for installation, avoiding the traditional method of using spring belts or drawstrings to fix it, but when there is a size mismatch, the clamping is unstable, and the common drawstring is fixed by manual knotting, which makes it easy to loosen during the knotting process, which greatly facilitates the use of the staff.
