Description

Technical Field

[0001] The utility model relates to the technical field of bag filters, and in particular to a bag filter with a compression sealing structure. Background Art

[0002] Bag filters are a versatile filtering device featuring a novel structure, compact size, simple and flexible operation, energy saving, high efficiency, airtight operation, and strong adaptability. Bag filters are a new type of filtration system. A metal mesh basket supports the filter bag. Liquid flows in through the inlet, passes through the bag, and exits through the outlet, trapping impurities. The filter bag can be replaced and continued in use. However, the filter bag is inconvenient to install and difficult to remove, which can hinder its use and easily lead to leaks due to insufficient sealing.

[0003] The patent specification with announcement number CN220159365U discloses a bag filter with a quick-release compression and sealing function. The sealing ring is placed in the installation frame, and then the top plate is placed on the upper end of the sealing ring, and the position of the fixing hole is adjusted so that the fixing hole is opposite to one end of the connecting rod, and then the rotating block is rotated. At this time, the connecting rod and the gear rotate. Through the cooperation of the gear and the teeth, the connecting rod can be moved downward until one end of the connecting rod is inserted into the fixing hole, thereby realizing the compression installation of the top plate and the filter bag for filtering use. At the same time, the provided sealing ring can achieve a sealing effect, otherwise it is convenient for disassembly.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: during the use of the above device, one end of the connecting rod needs to be inserted into the fixing hole to realize the compression installation of the top plate and the filter bag. The operation process is relatively complicated and requires accurate positioning of the fixing hole and the connecting rod. It requires precision and complexity, which will increase labor costs. Therefore, further improvement is needed. Utility Model Content

[0024] The following will be combined with 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.

[0025] like Figure 1 As shown, this embodiment proposes a bag filter with a compression sealing structure, including an operating cylinder 1, the upper end of which is fixedly connected to a top ring 2, the interior of the operating cylinder 1 is movably connected to a placement ring 3, and the interior of the top ring 2 is movably provided with a compression assembly 4.

[0026] like Figure 2 As shown, an annular groove 11 is provided at the upper end of the operating cylinder 1, and a clamping groove 12 is provided on the inner wall of the operating cylinder 1. The clamping groove 12 is connected to the annular groove 11. The presence of the annular groove 11 makes it easy to place the ring 3 inside the operating cylinder 1 so that it can rotate freely, that is, the protrusion 31 can rotate freely along the annular groove 11.

[0027] like Figure 3 As shown, a slide groove 21 is provided on the inner wall of the top ring 2, a square groove 22 is provided on the inner wall of the top ring 2, and a movable groove 23 is provided on the inner wall of the top ring 2. The movable groove 23 is connected with the interior of the square groove 22. The square groove 22 is located directly above the card slot 12. The slide groove 21 is connected with the ring groove 11. The existence of the movable groove 23 enables the movement of objects outside the top ring 2 to synchronously drive the movement of objects inside the top ring 2. The square groove 22 is used to place extruded objects to compress the bag filter.

[0028] like Figure 4As shown, a protrusion 31 is fixedly connected to the outer surface of the placement ring 3, a handle rod 32 is fixedly connected to the upper end of the placement ring 3, and a bag filter bag 33 is fixedly connected to the lower end of the placement ring 3. The protrusion 31 is rotatably connected to the inside of the ring groove 11, and the protrusion 31 is slidably connected to the slide groove 21. The protrusion 31 is slidably connected to the card groove 12. The handle rod 32 facilitates the movement of the placement ring 3, so that the staff does not need to directly contact the placement ring 3.

[0029] like Figure 5 As shown, the clamping assembly 4 includes a support rod 41 movably arranged inside the top ring 2, the upper end of the support rod 41 is fixedly connected to a spring 42, the lower end of the support rod 41 is fixedly connected to a pressure block 45, the outer surface of the support rod 41 is fixedly connected to a moving rod 43, one end of the moving rod 43 is fixedly connected to a handle plate 44, the support rod 41 is slidably arranged in the inner middle section of the square groove 22, the pressure block 45 is slidably arranged on the inner bottom side of the square groove 22, the upper end of the spring 42 is fixedly connected to the inner wall of the square groove 22, and the moving rod 43 passes through the interior of the moving groove 23.

[0030] The working principle and usage instructions of the present invention are as follows: when the bag filter needs to be compressed and sealed, the staff first needs to take out the placement ring 3, and then the staff needs to pull the handle rod 32 to align the protrusion 31 with the slide groove 21 in the top ring 2. After the protrusion 31 moves to the position of the ring groove 11, the staff pulls the handle plate 44 to drive the moving rod 43 to move along the moving groove 23. At this time, the moving rod 43 will drive the support rod 41 to move upward inside the square groove 22, and the spring 42 will be compressed until the support rod 41 drives the pressure block 45 to completely enter the inside of the square groove 22. At this time, the staff can turn the handle rod 32 to drive the placement ring 3 is rotated along the annular groove 11 until the protrusion 31 touches the clamping groove 12. At this time, the handle rod 32 can be pressed to make the protrusion 31 enter the clamping groove 12. At this time, the handle plate 44 is released, and the spring 42 will return to its original state under the action of the elastic force. That is, the spring 42 will simultaneously push the support rod 41 and the pressure block 45 to move along the square groove 22. When the spring 42 returns to its original state, the pressure block 45 is completely placed in the annular groove 11. At this time, the pressure block 45 will squeeze the protrusion 31 to prevent the protrusion 31 from escaping from the inside of the clamping groove 12, thereby realizing the compression installation of the top plate and the bag filter bag 33 for filtering use. At the same time, the provided sealing ring can achieve a sealing effect.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
