[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0023] Reference Figure 1-Figure 5 A medium-efficiency bag filter with quick-detachable filter bag comprises a body 1 and a filter bag 2. The top wall of the body 1 is provided with a plurality of mounting grooves in a circumferential shape. A first threaded rod 3 is horizontally rotatably mounted in the mounting groove. A slider 4 is threadedly sleeved on the first threaded rod 3. An arc-shaped support plate 5 is fixedly mounted on the lower surface of the slider 4 through a connecting rod. The top inner wall of the filter bag 2 is tightly against the plurality of support plates 5.

[0024] The bottom of the body 1 is fixedly installed with multiple mounting plates in a circumferential shape, and a rotating shaft 6 is rotatably installed on the surface of the mounting plate. Sprocket wheels 7 are fixedly sleeved on the rotating shaft 6 and the first threaded rod 3. Every two sprocket wheels 7 located on the same longitudinal horizontal line are meshed and wound with a chain 8. The multiple rotating shafts 6 are controlled to rotate by a driving assembly;

[0025] The driving assembly includes a rotating rod 9 vertically rotatably mounted in the device body 1, a plurality of meshing bevel gears 10 and a transmission component. The plurality of bevel gears 10 are respectively fixedly sleeved on the rotating rod 9 and the plurality of rotating shafts 6. The transmission component is used to control the rotation of the rotating rod 9. The transmission component includes a worm wheel 11 and a worm 12. The bottom end of the rotating rod 9 passes through the device body 1. The worm wheel 11 is fixedly sleeved on the bottom end of the rotating rod 9. A placement plate is fixedly mounted on the lower surface of the device body 1. The worm 12 is horizontally rotatably mounted on the placement plate and meshingly connected with the worm wheel 11.

[0026] When it is necessary to install the filter bag 2, first align the inner wall of the top opening of the filter bag 2 with the side of the multiple support plates 5 that are away from each other, and then control the rotation of the rotating rod 9 by turning the worm gear 12. Under the transmission action of the multiple bevel gears 10, the multiple rotating shafts 6 will rotate together, and then under the action of the multiple sprocket wheels 7 and the multiple chains 8, the multiple first threaded rods 3 will rotate together, and the slider 4 threadedly sleeved on the first threaded rod 3 will be controlled to move the support plate 5 in the horizontal direction until the multiple support plates 5 are tightly against the inner wall of the filter bag 2, the filter bag 2 can be propped up and fixed. When it is necessary to disassemble, it is only necessary to control the multiple support plates 5 to approach each other by turning the worm gear 12 to release the support of the filter bag 2 by the multiple support plates 5. It is convenient and quick, avoids the cumbersome steps of using screw and nut fixings, improves the efficiency of disassembling and replacing the filter bag 2, and the installable filter bag 2 is no longer a certain size, thereby improving the practicality of the device.

[0027] A second threaded rod 13 is rotatably mounted on the surface of the support plate 5, and a clamping plate 14 is threadedly sleeved on the second threaded rod 13. The clamping plate 14 is restricted from rotating by a restriction component. The restriction component includes a restriction rod 15 fixedly mounted on the surface of the support plate 5, and the clamping plate 14 is threadedly sleeved on the restriction rod 15.

[0028] When installing the filter bag 2, it is necessary to insert the top of the filter bag 2 between the multiple support plates 5 and the multiple clamping plates 14. Then, when the multiple support plates 5 open the top of the filter bag 2, by rotating the second threaded rod 13, the clamping plate 14 threadedly sleeved on the second threaded rod 13 will move in the horizontal direction under the restriction of the restriction rod 15 until the clamping plate 14 presses the bag mouth of the filter bag 2 between itself and the support plate 5, thereby strengthening the fixing effect of the filter bag 2.

[0029] The surfaces of the clamping plate 14 and the support plate 5 are both bonded with an anti-skid layer made of rubber. The rubber anti-skid layer has good elasticity and viscosity, thereby increasing the friction between the contact surfaces of the clamping plate 14 and the support plate 5 and the filter bag 2.

[0030] When the filter bag 2 needs to be installed, the inner wall of the top opening of the filter bag 2 is first aligned with the side of the multiple support plates 5 that are away from each other, and then the multiple rotating shafts 6 are controlled to rotate together by the driving component, and then the multiple first threaded rods 3 are driven to rotate together under the action of the multiple sprocket wheels 7 and the multiple chains 8, and the slider 4 threadedly sleeved on the first threaded rod 3 is controlled to move the support plate 5 in the horizontal direction until the multiple support plates 5 are tightly against the inner wall of the filter bag 2, the filter bag 2 can be propped up and fixed. When it needs to be disassembled, it only needs to control the rotation of the multiple rotating shafts 6 by the driving component to make the multiple support plates 5 approach each other, and release the support of the multiple support plates 5 to the filter bag 2. It is convenient and quick, avoids the cumbersome steps of using screw and nut fixings, improves the efficiency of disassembling and replacing the filter bag 2, and the installable filter bag 2 is no longer a certain size, thereby improving the practicality of the device.

[0031] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0032] The above description is only a preferred specific implementation manner 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 within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
