Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a dust removal frame with a fixed structure. Background Art

[0002] The dust collector frame, also known as the dust bag cage, is an indispensable accessory for bag dust collectors. It is used as a frame to support the dust filter bags. It can be compatible with six, eight, ten, twelve, sixteen, eighteen, twenty, and twenty-four ribs. The role of the dust collector frame is very important and is widely used in dust removal industry, chemical industry and other industrial places.

[0003] As disclosed in the utility model with application number 202223356726.8, a detachable dust removal frame is provided. The utility model provides a detachable dust removal frame with the following beneficial effects: the utility model is provided with a disassembly mechanism, by inserting the fixed plate into the fixed sleeve, the fixed plate squeezes the two blocks to move to the opposite side during the downward pressure, and the fixed plate continues to press down and the blocks automatically bounce into the slot under the action of the reset spring, and limit the fixed plate, thereby fixing the fixed sleeve and the mounting frame. When disassembly is required, first rotate the nut to the right to release the limiting effect between the nut and the fixed sleeve, and then rotate the threaded rod to drive the two movable plates to move to the opposite side so that the two blocks are moved out of the slot to release the limiting effect on the fixed plate. The operation is simple and convenient, and it is easy to use, which is convenient for subsequent maintenance work.

[0004] Similar to the above application, there are still some deficiencies:

[0005] This type of detachable dust collector frame is easy to disassemble and operate, but it does not have a fixed structure for the dust filter bag. It only uses the friction between the frame and the dust removal port to limit and fix the filter bag. There may be problems such as gaps, which may cause the dust filter bag to fall off and leak out, affecting its use. In addition, backflow gas is generally used to reversely clean the dust filter bag. Using only backflow airflow cannot achieve a good cleaning effect. Some dust adhering to the dust filter bag cannot fall off, resulting in reduced dust removal efficiency and increased maintenance frequency.

[0006] Therefore, a dust removal skeleton with a fixed structure is designed to optimize the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0024] Example 1

[0025] like Figures 1-4As shown, this embodiment provides a dust removal frame with a fixed structure, including a sleeve 1, a vertical frame 2 is evenly installed on the top of the sleeve 1, a horizontal frame 3 is evenly welded and fixed inside the vertical frame 2, a limiting tube 4 is installed on the top of the vertical frame 2, a fixing ring 5 is evenly provided on the inner side wall of the vertical frame 2, a sleeve 6 is evenly provided inside the fixing ring 5, and a top rod 7 is slidably connected to the inside of the sleeve 6. A limiting ring 8 is fixed on the outside of the top rod 7, and a spring 9 is fixed on one side of the limiting ring 8, and the spring 9 is sleeved on the outside of the top rod 7. The inside of the vertical frame 2 and the limiting ring 8 are fixed on the outside of the vertical frame 2. A fixing frame 10 is fixed at the lower position of the positioning tube 4, and a movable rod 11 is slidably installed in the middle position of the fixing frame 10. A positioning ring 12 is fixed to the outside of the movable rod 11, and a spring 2 is sleeved on the outside of the movable rod 11 and at the bottom of the positioning ring 12. Conical blocks 14 are evenly installed on the outside of the movable rod 11, an adjusting ring 15 is installed on the internal thread of the limiting tube 4, and a conical ring 16 is fixed to the bottom of the adjusting ring 15. Limiting blocks 18 are evenly installed on the outside of the limiting tube 4, and an inclined block 19 is fixed at the end of the limiting blocks 18 that are close to each other, and a spring 3 20 is sleeved on the outside of the limiting block 18.

[0026] The movable rod 11 can be connected to an external driving source. When the backflow airflow cleans the dust filter bag, the driving source is started to drive several groups of movable rods 11 to move up and down, and the movable rod 11 drives the cone block 14 to move up and down, and the cone block 14 pushes the top rod 7 to move outward during the downward movement, and the end of the top rod 7 pushes outward and supports the dust filter bag so that the dust filter bag bulges. When the cone block 14 moves up, the top rod 7 retracts into the sleeve 6 under the elastic force of the spring 19, and the top rod 7 does not contact the dust filter bag, and the dust filter bag returns to its original state, quickly lifting the dust filter bag to quickly remove the adhered dust. After the sleeve 1 is placed in the dust filter bag, the limit tube 4 is engaged between the dust filter bag and the mounting groove, and then the adjusting ring 15 is turned downward to make the conical ring 16 move downward, and the conical ring 16 pushes the limit block 18 outward until the limit block 18 is tightly fitted to the inner wall of the dust filter bag, and at the same time, the dust filter bag is more firmly fixed on the inner wall of the mounting port.

[0027] Example 2

[0028] In this embodiment, if Figures 1-4 As shown, a buffer block 21 is fixed to each end of the push rods 7 that is away from each other, and the buffer block 21 is an elastic block.

[0029] The buffer block 21 made of elastic material provides the whole with a certain buffering and protective effect, thereby alleviating the extrusion deformation of the whole caused by the airflow.

[0030] In this embodiment, a protective layer is provided on the outer side of each cone block 14 , and the protective layer is a wear-resistant protective layer.

[0031] The wear-resistant protective layer provides better protection for the outer side of the cone block 14 and reduces wear and deformation caused by friction.

[0032] In this embodiment, a fixing rod 17 is fixed to the top of the adjustment ring 15 , and a rotating block is provided at the top end of the fixing rod 17 .

[0033] The arrangement of the fixing rod 17 and the rotating block facilitates the rotation of the fixing rod 17 by the staff, thereby driving the adjusting ring 15 to move up and down.

[0034] In this embodiment, one side of the inclined block 19 is configured as an inclined surface, and a protective film is provided on the outer side of the inclined block 19 .

[0035] The provision of the inclined surface increases the fit between the inclined block 19 and the outer side of the conical ring 16 , while the protective film improves the protective effect of the inclined block 19 .

[0036] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
