Description

Technical Field

[0001] This utility model belongs to the field of bag filter technology, and in particular relates to a bag filter that is easy to remove filter residue. Background Technology

[0002] Bag filters are a common type of liquid filtration equipment, widely used in industries such as chemical, food, and pharmaceutical. They achieve purification by trapping solid particles in the fluid through filter bags. However, in actual use, if the filter residue accumulated on the surface of the filter bags is not removed in time, it will affect the filtration efficiency and fluid quality.

[0003] Traditional bag filters use a fixed installation method for the filter bags, which means that when cleaning the filter cake, the staff needs to spend a lot of time and effort to disassemble the entire filter bag. Frequent disassembly not only increases the labor intensity of the workers, but also leads to prolonged equipment downtime, which greatly affects the production schedule. In addition, when manually cleaning the filter cake, the filter bags are easily damaged due to the uncertainty of the operation.

[0004] To address these issues, we provide a bag filter that facilitates the removal of filter residue. Utility Model Content

[0005] The purpose of this utility model is to provide a bag filter that facilitates the removal of filter residue. By combining the flipping component, the vibration motor, the nozzle, and the cleaning component, it solves the problem that the filter bags in the existing bag filters are fixedly installed, which makes the process of cleaning filter residue cumbersome.

[0014] The present invention is further configured such that a card plate is fixedly connected to the top of both sides of the inner cavity of the feeding hopper, and a primary filter frame is movably connected to the surface of the card plate. The primary filter frame can perform preliminary filtration on the fluid poured into the inner cavity of the feeding hopper, and the primary filter frame is easy to disassemble, which can further improve the filtration effect of the filter.

[0015] The present invention has the following beneficial effects.

[0016] 1. When a large amount of filter residue accumulates in the inner cavity of the filter bag of this utility model, the limiting frame can be moved upward to move the insert rod on the inner wall of the limiting frame out of the slot cavity at one end of the handle. The handle is rotated, and the handle drives the rotating rod, the mesh frame and the filter bag to rotate until the filter bag opening faces downward. Then, the water receiving plate is connected to the external water supply equipment, and water is sprayed through the nozzle. At the same time, the vibration of the vibration motor is used to efficiently clean the filter residue in the inner cavity of the filter bag with a dual cleaning structure. Moreover, after the filter residue falls into the cleaning chamber, the cleaning chamber can be pulled out by the push-pull plate to clean the filter residue. The operation is simple and the cleaning effect is good.

[0017] 2. This utility model has a dual filtration structure. First, the fluid is initially filtered through the primary filter frame inside the hopper. The fluid after the initial filtration is then filtered a second time through the filter bag, which can effectively improve the filtration effect. The fluid after the second filtration flows out through the through hole at the bottom of the cleaning chamber, thus meeting the requirements for fluid filtration. Attached Figure Description

The flipping assembly 5 includes a rotating rod 501, one end of the rotating rod 501 fixedly connected to the surface of the mesh frame 2, and the other end of the rotating rod 501 fixedly connected to a turntable 502. A handle 503 is fixedly connected to the top of the turntable 502. A groove 504 is opened at the top of one side of the shell 1. A movable block 505 is movably connected to the inner cavity of the groove 504. A spring 506 is fixedly connected to the top of the movable block 505. A limiting frame 507 is fixedly connected to one side of the movable block 505. A rod on the inner wall of the limiting frame 507 is movably connected to a slot at one end of the handle 503.

[0028] Specifically: When it is necessary to clean the filter residue in the filter bag 3, the limiting frame 507 can be moved upward until the insert rod on its inner wall moves out of the slot cavity at one end of the handle 503. Then the handle 503 can be rotated, and the handle 503 drives the rotating rod 501 to rotate. The rotating rod 501 drives the mesh frame 2 and the filter bag 3 in its inner cavity to rotate until the opening of the filter bag 3 faces downward. At this time, the water receiving plate 7 is connected to the external water supply equipment, and water is sprayed onto the bottom of the mesh frame 2 and the filter bag 3 through the nozzle 8. At the same time, the vibration motor 4 is turned on. The filter residue in the inner cavity of the filter bag 3 is efficiently cleaned through the dual cleaning structure of vibration and water spraying. After the filter residue falls into the cleaning chamber 603, the cleaning chamber 603 is pulled out by the push-pull plate 13 to clean the filter residue in its inner cavity.

The fluid after preliminary filtration continues to flow into the inner cavity of the filter bag 3 through the discharge hood 10 at the bottom of the upper hopper 9. The filter bag 3 performs secondary filtration on the fluid. The fluid after secondary filtration flows into the cleaning chamber 603 and flows out through the through hole at the bottom of the cleaning chamber 603. As filtration proceeds, a large amount of filter residue will accumulate in the inner cavity of the filter bag 3. Stop pouring the fluid and move the limiting frame 507 upward until the insertion rod on its inner wall moves out of the slot at one end of the handle 503. Then, the hand lever 503 can be rotated, which drives the rotating rod 501 to rotate. The rotating rod 501 drives the mesh frame 2 and the filter bag 3 inside the cavity to rotate until the opening of the filter bag 3 faces downward. At this time, the water receiving plate 7 is connected to the external water supply equipment. The external water supply equipment injects water with water pressure into the water receiving plate 7, and sprays water over a large area to the bottom of the mesh frame 2 and the filter bag 3 through the nozzle 8. At the same time, the vibration motor 4 is turned on. The filter residue inside the filter bag 3 is efficiently cleaned through the dual cleaning structure of vibration and water spraying. After the filter residue falls into the cleaning chamber 603, the cleaning chamber 603 is pulled out by the push-pull plate 13 to clean the filter residue inside the cavity.
