Description

Technical Field

[0001] The utility model relates to bag dust removal equipment, belonging to the technical field of bag dust removal equipment. Background Art

[0002] The dust bag is the heart of the bag dust collector. It is generally called a dust bag or a dust filter bag. The dust bag is a key part in the operation of the bag dust collector. Usually the cylindrical filter bag is hung vertically in the dust collector. It is a dust removal device that uses a bag filter element made of fiber woven material to capture solid particles in the dust-containing gas. Its working principle is that the dust particles are intercepted when they collide with the fibers due to the inertial force when they go around the filter cloth fibers.

[0003] Chinese patent number CN113908632A proposes a bag dust removal device, which can scrape the outer wall of the dust bag through the setting of a cleaning component. The coordination of the cleaning brush and the pulse can make the cleaning effect of the dust bag of the device more outstanding. However, the service life of the dust bag is limited. The design is not convenient for disassembly, cleaning and replacement of the dust bag, and its practicality is poor. Now there is an urgent need for a bag dust removal device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figure 1-Figure 5 The utility model provides a technical solution: a bag dust removal device, including a cylindrical shell 1, a compression fan 2, a fixed seat 3, a limit seat 4, a limit card block 5, a movable seat 6, a limit card slot 7, a plastic splint 8 and a dust collecting bag 9. The compression fan 2 is installed on the upper end surface of the cylindrical shell 1, and the fixed seat 3 is installed inside the cylindrical shell 1. The limit seat 4 is arranged in front of the fixed seat 3. The limit card block 5 is slidably arranged inside the limit seat 4. The movable seat 6 is slidably arranged under the fixed seat 3. The inner side surface of the movable seat 6 is provided with a plastic splint 8 for clamping the dust collecting bag 9. The outer side surface of the movable seat 6 is provided with a limit card slot 7, and the lower end surface of the movable seat 6 is fixedly provided with a dust collecting bag 9.

[0024] As the first embodiment of the utility model: the upper end surface of the compressor fan 2 is provided with an air inlet pipe 21, and the air inlet pipe 21 is connected to the external dust collecting hopper, and the compressor fan 2 is exhausted through the air inlet pipe 21 and the external dust collecting hopper, and a hole is provided inside the fixed seat 3 and is connected with the output end of the compressor fan 2, and the compressor fan 2 discharges air downward through the fixed seat 3, and a positioning block 31 is provided on the lower end surface of the fixed seat 3, and a positioning groove 61 is provided on the upper end surface of the movable seat 6, and the positioning block 31 and the positioning groove 61 are slidably engaged with each other. The design of the positioning block 31 and the positioning groove 61 makes the movement of the movable seat 6 more stable, and a slide groove 41 is provided inside the limit seat 4, and the limit card block 5 slides tightly along the inner wall of the slide groove 41, and a return spring 52 is provided inside the slide groove 41, and the return spring 52 can help the limit card block 5 to reset, and the limit card block 5 and the limit card groove 7 are engaged with each other. The design of the limit card block 5 and the limit card groove 7 can fix and limit the position between the limit seat 4 and the movable seat 6, and the limit card block The outer end of 5 is provided with a connecting handle 51 and the connecting handle 51 passes through the limiting seat 4. The connecting handle 51 is convenient for users to pull and drive the limiting card block 5 to move together. The plastic splint 8 and other specifications are provided in several groups and a certain angle is formed between the plastic splint 8 and the inner wall of the movable seat 6. The lower end surface of the fixed seat 3 is provided with an extrusion seat 33. The lower end of the outer side surface of the extrusion seat 33 is conical. The extrusion seat 33 can squeeze the inclined plastic splint 8, so that it shrinks inward and clamps the dust collecting bag 9. The inner side surface of the plastic splint 8 is bonded with an anti-slip strip 81, which is made of wear-resistant rubber. The anti-slip strip 81 can increase the friction between the plastic splint 8 and the dust collecting bag 9, so that the clamping is more stable and firm. The lower end surface of the fixed seat 3 is provided with a supporting frame 32, which can prop up the dust collecting bag 9, so that its filtering effect is better. The upper end of the dust collecting bag 9 is provided with a fixing frame 91, which is convenient for users to install the dust collecting bag 9.

[0025] As a second embodiment of the present utility model: the user connects the air inlet pipe 21 with the external dust collecting hopper, the compression fan 2 continuously draws air and discharges the air mixed with dust downward through the fixed seat 3, wherein the dust is intercepted and collides with the filter cloth fibers of the dust collecting bag 9 due to the inertial force, and is concentrated inside the dust collecting bag 9. When the user needs to disassemble the dust collecting bag 9, he first pulls the connecting handle 51 outward so that the connecting handle 51 drives the limiting block 5 to move together and compress the reset spring 52, thereby releasing the mutual engagement state between the limiting block 5 and the limiting slot 7, and then pulls the moving seat 6 downward so that the moving seat 6 moves downward along the surface of the positioning block 31 through the positioning slot 61, and the moving seat 6 moves downward. During the movement, the plastic clamping plate 8 disengages from the squeezing seat 33 and bounces up within its own elastic limit, and no longer clamps the fixed frame 91 at the upper end of the dust collecting bag 9. At this time, the dust collecting bag 9 can be freely removed and can be cleaned or replaced. When the dust collecting bag 9 needs to be installed, the user first clamps the fixed frame 91 upward between the plastic clamping plate 8 and the inner wall of the movable seat 6, and then pushes the movable seat 6 upward so that the upper end surface of the movable seat 6 abuts against the lower end surface of the fixed seat 3. During the pushing process, the squeezing seat 33 continuously squeezes the plastic clamping plate 8, so that the plastic clamping plate 8 shrinks inward and clamps and fixes the dust collecting bag 9. At the same time, the limiting block 5 and the limiting slot 7 engage with each other to fix the position of the movable seat 6.
