[0003] The dust filtering device disclosed in Chinese patent CN218871595U has the following working principle: the exhaust fan absorbs the air mixed with dust from the outside into the dust filter cylinder, and the air is filtered through the first filter screen and the second filter screen. The filtered air runs out from the right end of the dust filter cylinder. After the filtering is completed, the electric switch door is started to fully expose the discharge hole, and the dust flows out along the discharge cylinder and finally falls into the inside of the storage hopper.

DETAILED DESCRIPTION

[0037] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] Reference Figures 1 to 12As shown: a dust filtering and processing device, including a workbench 1, a multi-angle adjustment device 2 is arranged in the middle of the workbench 1, a mounting plate 3 is arranged at the upper end of the multi-angle adjustment device 2, a dust filter cartridge 4 is arranged on the mounting plate 3, the dust filter cartridge 4 includes a feed bin 41, a filter bin 42 and an exhaust bin 43, the feed bin 41, the filter bin 42 and the exhaust bin 43 are arranged in sequence, a first cover body 44 for preventing large particles from entering is arranged at the feed port of the feed bin 41, a second cover body 45 for preventing foreign matter from entering is arranged at the exhaust port of the exhaust bin 43, a filtering mechanism 5 is arranged on one side of the inside of the filter bin 42, and the filtering mechanism 5 comprises a filtering structure 51, the filtering structure 51 comprises a filter screen 511, the diameter of the filter screen 511 is the same as the inner diameter of the filter bin 42, an exhaust structure 52 for forming a negative pressure in the dust filter cartridge 4 is arranged in the exhaust bin 43, the exhaust structure 52 comprises a driving motor 521 and an exhaust fan blade 522, the exhaust fan blade 522 is connected to the output shaft of the driving motor 521, a filter screen cleaning mechanism 6 for cleaning the filter screen 511 is arranged on the other side of the filter bin 42, and a second connecting structure 7 is arranged outside the dust filter cartridge 4, and the second connecting structure 7 connects the feed bin 41, the filter bin 42 and the exhaust bin 43.

[0039] Before the device is put into operation, the staff places the filter bin 42 between the feed bin 41 and the filter bin 42, and then uses the second connecting structure 7 to connect the feed bin 41, the filter bin 42 and the exhaust bin 43. The multi-angle adjustment device 2 can adjust the position of the mounting plate 3 at any time, so that the dust filter cartridge 4 can face different directions. Then the exhaust structure 52 works, and the driving motor 521 drives the exhaust fan to rotate. The exhaust fan makes the air in the dust filter cartridge 4 flow from the feed bin 41 toward the discharge bin, forming a low pressure at the air inlet of the feed bin 41, sucking the external air into the dust filter cartridge 4, and when the air flows through the filter structure 51, the dust in the air adheres to the filter The gas passes through the filter 511 and is discharged from the exhaust bin 43. After the device has been working for a long time, more and more dust is attached to the filter 511, which blocks some of the meshes of the filter 511, affecting the flow of air inside the dust filter cartridge 4, and reducing the processing efficiency of the dust filtering treatment device. By setting the filter cleaning mechanism 6, the filter 511 filters the dust in the air while the filtering and cleaning mechanism works to clean the dust on the filter 511, maintaining the ability of the filter 511 to pass through the air, so that the suction force formed in the dust filter cartridge 4 when the exhaust structure 52 is working remains unchanged, thereby maintaining the processing efficiency of the dust treatment device.

[0040] Reference Figure 3 , Figure 5 and Figure 6As shown: one end of the filter bin 42 is an outer convex section 421, and a discharge port 422 is provided at the lower end of the outer convex section 421. The filtering structure 51 also includes a conical frame 512, and the smaller end of the conical frame 512 faces the feed bin 41. A plurality of fan-shaped mounting grooves 5121 are provided on the surface of the conical frame 512. There are a plurality of filter screens 511, and the plurality of filter screens 511 are respectively arranged in the plurality of fan-shaped mounting grooves 5121. A material guide plate 513 is arranged around the conical frame 512, and the material guide plate 513 extends into the outer convex section 421. A transmission connecting shaft 514 is arranged in the middle of the conical frame 512, and the axis of the transmission connecting shaft 514 is colinear with the axis of the conical frame 512. The smaller end of the conical frame 512 is connected to the transmission connecting shaft 514, and one end of the transmission connecting shaft 514 is connected to the output shaft of the driving motor 521.

[0041] When the driving motor 521 drives the exhaust fan blades 522 to rotate, the output shaft of the driving motor 521 also drives the transmission connecting shaft 514 to rotate, and the transmission connecting shaft 514 drives the conical frame 512 to rotate. The guide plate 513 rotates inside the outer convex section 421, and the filter screen 511 rotates following the conical frame 512. The conical frame 512 is used to install the filter screen 511, which increases the area of ​​the filter screen 511 and improves the efficiency of gas passing through the filter screen 511. When the conical frame 512 rotates, the dust attached to the filter screen 511 is moved toward the surroundings of the conical frame 512 by the centrifugal force. At the same time, the dust is also pushed by the airflow, so that the dust moves along the surface of the conical frame 512. When the dust moves to the guide plate 513, it enters the outer convex section 421 along the guide plate 513 and flows out from the discharge port 422, thereby making the filter screen 511 have the ability of self-cleaning.

[0042] Reference Figure 3 , Figure 5 and Figure 7 As shown: the filter cleaning mechanism 6 includes an unpowered drive structure 61, which is arranged at the front end of the filter bin 42, and the unpowered drive structure 61 includes an annular track 611, which is connected to the filter bin 42, and an annular plate 612 is arranged on the annular track 611, and the annular plate 612 is slidably connected to the annular track 611, and a plurality of unpowered fan blades 613 are arranged in an annular array in the middle of the annular plate 612, and a plurality of cleaning arms 62 for cleaning the surface of the filter 511 are arranged in an annular array on one side of the annular plate 612 facing the filter 511.

[0043] The driving motor 521 drives the exhaust fan blades 522 to rotate, so that negative pressure is formed in the dust filter cartridge 4, and external air enters the dust filter cartridge 4, and an airflow is formed in the dust filter cartridge 4 in the direction of flow from the feed bin 41 toward the exhaust bin 43. The airflow blows on the surface of the unpowered fan blades 613, applies thrust to the unpowered fan blades 613, and forms a component force on the surface of the unpowered fan blades 613. The component forces on several unpowered fan blades 613 form a combined force to drive the annular plate 612 to rotate around the annular track 611. The rotation of the annular plate 612 drives the cleaning arm 62 to rotate, and the cleaning arm 62 cleans the surface of the filter screen 511, thereby realizing the cleaning of the dust on the surface of the filter screen 511 without installing a driving device.

[0044] Reference Figure 7 and Figure 8 As shown: the cleaning arm 62 includes a first elastic support arm 621, one end of the first elastic support arm 621 is connected to the annular plate 612, the other end of the first elastic support arm 621 is provided with a strip plate 622, one end of the strip plate 622 is hinged to the first elastic support arm 621, a T-slot 6221 is provided on the strip plate 622, bristles 623 are inserted in the T-slot 6221, the other end of the strip plate 622 is provided with a second elastic support arm 624, one end of the second elastic support arm 624 is connected to the first elastic support arm 621, and the other end of the second elastic support arm 624 is hinged to the other end of the strip plate 622.

[0045] If the air flow in the middle of the annular plate 612 is larger, the inner diameter of the annular plate 612 needs to be larger. Therefore, the first elastic support arm 621 is far away from the center of the annular plate 612. The first elastic support arm 621 can only provide support force for one end of the strip plate 622. By setting the second elastic support arm 624, the second elastic support arm 624 provides support force for the other end of the strip plate 622, so that the strip plate 622 is parallel to the outer surface of the conical frame 512, and the bristles 623 are in close contact with the filter screen 511. When the annular plate 612 rotates, it drives the first elastic support arm 621 to rotate, and the second elastic support arm 624 drives the bristles 623 to clean the filter screen 511, thereby cleaning the mesh surface of all filter screens 511.

[0046] Reference Figure 5 , Figure 6 and Fig. 9As shown: a first connecting structure 53 is arranged between the transmission connecting shaft 514 and the driving motor 521, and the first connecting structure 53 includes a connecting shaft 531, one end of the connecting shaft 531 is connected to the output shaft of the driving motor 521, and a plurality of slide grooves 5311 are opened on the surface of the other end of the connecting shaft 531, a sliding sleeve 532 is sleeved on the connecting shaft 531, and a plurality of sliders 533 are arranged inside the sliding sleeve 532, and the sliders 533 cooperate with the slide grooves 5311, and a first flange 534 and a second flange 535 are arranged on the other end of the connecting shaft 531, the first flange 534 is connected to the connecting shaft 531, and the second flange 535 is connected to the transmission connecting shaft 514, and a plurality of threaded columns 5351 are arranged in a ring array on the second flange 535.

[0047] The filter structure 51 is installed in the filter bin 42, and the exhaust structure 52 is installed in the exhaust bin 43. After aligning the filter bin 42 with the exhaust bin 43, pull the first flange 534 to pull the first flange 534 out of the exhaust bin 43, and the first flange 534 drives the sliding sleeve 532 to move, and then rotate the first flange 534 to align the first flange 534 with the second flange 535, and then abut the first flange 534 with the second flange 535. The first flange 534 passes through the screw column, and the first flange 534 and the second flange 535 are fixedly connected with each other using nuts, and then the filter bin 42 and the exhaust bin 43 are connected, and the sliding sleeve 532 moves back along the connecting shaft 531, so as to facilitate the staff to connect the output shaft of the drive motor 521 with the transmission connecting shaft 514.

[0048] Reference Fig. 9 As shown: a first annular baffle 536 is sleeved on the middle part of the connecting shaft 531, the first annular baffle 536 is fixedly connected to the connecting shaft 531, a first pressure spring 537 is arranged on one side of the first annular baffle 536, one end of the first pressure spring 537 is connected to the first annular baffle 536, and the other end of the first pressure spring 537 is connected to the first flange 534.

[0049] When the staff connects the first flange 534 and the second flange 535, they need to pull the first flange 534 out of the exhaust chamber 43 first, which affects the assembly efficiency of the device. By setting the first annular baffle 536 and the first pressure spring 537, when the first flange 534 is not connected to the second flange 535, the first pressure spring 537 applies a thrust to the first flange 534, pushing the sleeve 532 to move along the connecting shaft 531, so that the first flange 534 is outside the exhaust chamber 43 in the initial state, thereby eliminating the need for the staff to manually pull the first flange 534 out of the exhaust chamber 43, thereby improving the assembly efficiency of the device.

[0050] Reference Figure 3 and Figure 5As shown: there are several filter chambers 42, and the several filter chambers 42 are connected in sequence, and the several filter chambers 42 are interconnected. There are several filter structures 51, and the several filter structures 51 are respectively arranged in the several filter chambers 42. The filter nets 511 in each filter structure 51 are different, and the several filter nets 511 are arranged in sequence from weak to strong according to the filtering capacity. There are several filter cleaning mechanisms 6, and the several filter cleaning mechanisms 6 are respectively arranged at the front ends of the several filter structures 51.

[0051] Since one filtration will allow some dust to pass through the filter 511, resulting in the filtered air still containing dust, by setting a plurality of filter chambers 42, a filter structure 51 and a filter cleaning mechanism 6, when the exhaust structure 52 is working, the air passes through the plurality of filter chambers 42 in turn, and the filter 511 in the filter chamber 42 filters the dust in the air. The filter 511 arranged at the rear end has a smaller mesh size and is more efficient in separating dust and air, thereby achieving sufficient filtration of the air and making the exhausted air dust-free.

[0053] After the device is used for a long time, it needs to be maintained. After the maintenance of the filter bin 42 is completed, the device needs to be assembled. First, several filter bins 42 are connected in sequence to form a filter bin 42 group, and then the filter bin 42 group is placed between the feed bin 41 and the exhaust bin 43. Then the staff holds the rotating handle 724 and drives the rotating handle 724 to rotate. The rotating handle 724 drives the double-headed screw 723 to rotate. The double-headed screw 723 applies a pulling force to the two first arc-shaped brackets 721 to approach each other through the two screw sleeves 722, pulling the feed bin 41 and the exhaust bin 43 to approach each other along the two sliding seats 71 respectively. The feed bin 41 and the exhaust bin 43 are respectively connected to the two ends of the filter bin 42 group, so that it is convenient for the staff to disassemble and assemble the filter bin 42 for maintenance.
