DETAILED DESCRIPTION

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] Example 1:

[0034] like Figures 1 to 3 As shown, this embodiment provides a dust removal device for electrical automation equipment in a tobacco dust environment, including a collection box 1, a fan 3, an air duct, and a dust removal hood 28.

[0035] The top of the collection box 1 is a removable cover plate 5, and a filter screen 8 is located on the right side inside the collection box 1. The bottom of the collection box 1 is equipped with a pull-out drawer 2. A walking component is provided on the bottom side of the collection box 1 for moving the device. The walking component includes a wheel seat 6, which is installed on the lower surface of the collection box 1. Universal wheels 7 are rotatably connected inside the wheel seat 6.

[0036] The fan 3 is installed on the right side of the collection box 1. The output end of the fan 3 is fixedly connected to the inside of the collection box 1. A protective net 4 is fixedly connected to the side wall of the fan 3.

[0037] One end of the duct is connected to the left side of the collection box 1, and the other end of the duct is connected to the dust removal hood 28.

[0038] In this embodiment, in order to improve the problem that "in the prior art, the filter screen is not easy to disassemble, and it is difficult to clean or replace it regularly, resulting in excessive dust accumulation on the filter screen, reducing the filtration area and efficiency, and making the dust removal equipment unable to effectively remove pollutants in the air", the following settings are adopted.

[0039] The filter screen 8 is slidably installed in the collection box through the vertical slides on the front and rear sides. The vertical slides on both sides are respectively located on the front and rear side walls of the collection box 1. At the same time, quick fixing mechanisms are provided at the front and rear positions of the filter screen.

[0040] The quick-fixing mechanism includes mounting blocks 9 fixed to the front / rear sidewalls of the collection box. The upper part of the mounting block 9 has a mounting channel extending in a left-right direction. A connecting post 14 is slidably mounted within the mounting channel, and a reset mechanism is provided between the connecting post 14 and the mounting channel. A locking block 16 is fixed to the right end of the connecting post 14, extending to the right of the channel and engaging with the frame of the filter screen 8. The left end of the connecting post 14 extends out of the channel and has a connecting seat 13 with a connecting hole.

[0041] A fixing block 10 protruding to the left is fixed to the lower left side of the mounting block 9. The fixing block 10 is rotatably connected to a pull handle 11. A rotating plate 12 is fixedly connected to the pull handle 11, and the two together form an L-shaped structure. The upper end of the rotating plate 12 is rotatably connected to the connecting hole of the connecting seat 13 by a pin.

[0042] In order to avoid the rotation of the rotating plate 12 in the process of rotation, the connecting hole on the connecting seat 13 is a long hole, and the width of the long hole is slightly larger than the pin shaft.

[0043] In this embodiment, the installation channel is a stepped structure, including a large-diameter channel matched with the connecting column 14, and a small-diameter channel matched with the clamping block 16. The reset mechanism is a spring 15 sleeved on the connecting column 14, and a limiting portion is arranged at the left end of the large-diameter channel. The left end of the spring 15 is connected with the limiting portion, and the right end of the spring 15 is connected with the connecting column 14.

[0044] In order to facilitate the simultaneous operation of the front and rear two quick fixing mechanisms, the connecting plate 17 is connected between the front and rear two pull handles 11.

[0045] The working principle of this embodiment is as follows:

[0046] When performing the dust removal task, the operator needs to first move the device to the target area, then start the fan 3, so that the dust removal cover 28 enters the working state, and performs the dust removal work on the surface of the device and the surrounding environment, and then sends the dust into the collection box 1 through the air pipe, realizing the collection of dust.

[0047] When the device is used for a long time and needs to replace or clean the filter screen 8, first close the device, then open the cover plate 5, and then press the connecting plate 17. This action makes the pull handle 11 drive the rotating plate 12 to start rotating, and then pulls the connecting column 14 through the connecting seat 13, so that the spring 15 gradually contracts. With the contraction of the spring 15, the clamping block 16 gradually loosens from the inside of the filter screen 8, and finally completely separates. At this time, the fixing of the filter screen 8 is released, and only needs to be pulled up, so that the filter screen 8 can be taken out of the device for thorough cleaning or replacement, providing guarantee for the continuous and efficient operation of the device. The filter screen design of this embodiment is convenient to replace, which allows the worker to quickly disassemble and assemble the filter screen, so that the maintenance time can be significantly reduced, and the operation efficiency of the device can be improved.

[0048] Embodiment two:

[0049] As shown in Figures 1 to 4 Based on the embodiment one, the dust removal cover 28 can move up and down, and the specific structure is as follows.

[0050] The left side of the collection box 1 is fixedly connected with a fixed plate 18 extending to the left, and the fixed plate is fixedly installed with a lifting sleeve 19. The lifting sleeve 19 is provided with a lifting plate 26 slidingly matched with it in the up-down direction. The lifting plate 26 is connected with a lifting driving mechanism, and the lifting driving mechanism is used to drive the lifting of the lifting plate 26.

[0051] The air pipe includes a hard pipe 31 connected with the dust removal cover, and a telescopic pipe 27 connected with the collection box 1. The upper end of the lifting plate 26 is provided with a fixed hole, and the hard pipe 31 is fixedly installed at the fixed hole.

[0052] In this embodiment, a lifting motor 20 is fixedly connected to the side wall of the lifting sleeve 19 in the lifting drive mechanism. The lifting motor 20 drives the worm gear 21 to rotate, and the output end of the lifting motor 20 is fixedly connected to the worm gear 21. A rotating column 22 is rotatably connected inside the lifting sleeve 19. A worm wheel 23 is fixedly connected to the rotating column 22 and meshes with the worm gear 21. A gear 24 is also fixedly connected to the rotating column 22, and the worm wheel 23 and the gear 24 rotate synchronously. A rack 25 along the vertical direction is fixedly connected to the side wall of the lifting plate 26, and the gear 24 meshes with the rack 25.

[0053] When the height of the dust collector hood 28 needs to be adjusted, the lifting motor 20 is activated, causing the worm gear 21 to rotate. The rotation of the worm gear 21 drives the worm wheel 23, which meshes with it, to rotate. The rotation of the worm wheel 23 is further transmitted to the rotating column 22, which is fixedly connected to it, causing the rotating column 22 to rotate. The rotation of the rotating column 22 drives the gear 24 fixed to it to rotate. As the gear 24 rotates, the rack 25 meshes with it and begins to move upward along a predetermined track. The upward movement of the rack 25, through its connection with the rigid tube 31, drives the rigid tube 31 to move upward, thereby causing the dust collector hood 28 to move upward as a whole, completing the height adjustment. Through this series of mechanical linkages, the dust collector hood 28 can be quickly and accurately adjusted to the required height to meet the needs of different working environments, effectively improving dust removal efficiency and operational flexibility.

[0054] Example 3:

[0055] like Figure 4 As shown, in this embodiment, based on embodiment two, a cleaning brush 30 is provided near the opening inside the dust removal hood. The cleaning brush 30 is rotatably connected to the side wall of the dust removal hood 28. A cleaning motor 29 is fixedly connected to the side wall of the dust removal hood 28, and the output end of the cleaning motor 29 is connected to the cleaning brush 30.

[0056] When performing a dust removal task, the operator must first move the equipment to the target area, then start the fan 3 to put the dust removal hood 28 into working condition. At the same time, in order to enhance the dust removal effect, the operator should simultaneously start the cleaning motor 29 and activate the cleaning brush 30, so that it rotates under the drive of the cleaning motor 29 to clean the surface of the equipment and the surrounding environment. The dust during cleaning will be sucked in by the dust removal hood 28 and transported to the collection box 1 through the telescopic pipe 27 for collection.
