DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 As shown in FIG. 3 , an embodiment of the utility model proposes an aluminum processing dust removal device, comprising a first dust suction pipe 1 and a second dust suction pipe 3 connected thereto through a mounting frame 2. The first dust suction pipe 1 and the second dust suction pipe 3 are both erected on the ground through a support column 4. A negative pressure device 5 is provided at one end of the second dust suction pipe 3 away from the first dust suction pipe 1. A filter screen plate 6 is movably installed in the mounting frame 2. The mounting frame 2 is also provided with a shaking component for driving the filter screen plate 6 to shake. A discharge pipe 7 is provided at the bottom of the first dust suction pipe 1 near one end of the mounting frame 2. One end of the discharge pipe 7 is connected to the first dust suction pipe 1, and the other end of the discharge pipe 7 is provided with a collecting component for collecting aluminum chips. During operation, the first dust suction pipe 1 is placed in an environment where aluminum products are processed, and the negative pressure device 5 generates negative pressure to suck aluminum dust in the environment into the first dust suction pipe 1. The negative pressure device 5 can be a suction fan. After the aluminum dust enters the first dust suction pipe 1, the larger aluminum chips contained in the aluminum dust are blocked by the filter screen plate 6. These aluminum chips fall into the discharge pipe 7, and are then discharged into the collecting component through the discharge pipe 7 and collected by the collecting component. The shaking component is started as needed, and the shaking component drives the filter screen plate 6 to shake, thereby shaking the aluminum chips accumulated on the filter screen plate 6 into the discharge pipe 7 on one side thereof, thereby ensuring that the filter screen plate 6 does not accumulate too much aluminum chips, so that the dust removal efficiency of the filter screen plate 6 will not be affected, and the aluminum chips shaken off the filter screen plate 6 can also be collected by the collecting component for subsequent recycling.

[0022] like Figure 3—4, further, the shaking assembly includes: a spring 8, the cross section of the mounting frame 2 is concave, one end of at least one spring 8 is fixedly provided on each side of the filter screen plate 6, the other end of each spring 8 is fixedly connected to the inner wall corresponding to the mounting frame 2, and a lever 9 is fixedly provided on the top wall of the filter screen plate 6, the lever 9 passes through the mounting frame 2 and is slidably connected to the mounting frame 2. When the filter screen plate 6 needs to be shaken, the lever 9 is pressed, and since the filter screen plate 6 is connected to the inner wall of the mounting frame 2 through the spring 8, the lever 9 will push the filter screen plate 6 downward, and the lever 9 is released, and the lever 9 returns to its original position under the action of the spring 8, and the lever 9 is pressed multiple times, so that the filter screen plate 6 is shaken and the aluminum chips accumulated on it are shaken off.

[0023] like Figure 3 —5, further, it also includes a push plate 10, the push plate 10 is fixedly arranged on the top of the lever 9, a drive motor 11 is arranged on the top of the second dust suction pipe 3, a cam 12 is fixedly arranged on the output end of the drive motor 11, and the cam 12 is located above the push plate 10. In this embodiment, the cam 12 is located directly above the push plate 10, and when the cam 12 rotates, it hits the push plate 10, so that the push plate 10 moves downward. During operation, the drive motor 11 is started, and the rotation of the drive motor 11 drives the cam 12 to rotate, so that the cam 12 hits the push plate 10 reciprocatingly, pushing the push plate 10 to press the lever 9 downward, thereby causing the filter screen plate 6 in the installation frame 2 to shake and shake off the aluminum chips.

[0024] like Figure 1 —3, further, the collecting assembly includes: a connecting box 13, the top of the connecting box 13 is connected to the discharge pipe 7, a chute is provided on one side of the connecting box 13, a collecting box 14 is slidably provided in the chute, and a limiting assembly is provided on the side wall of the connecting box 13 to limit the collecting box 14 from sliding out of the chute. The collecting box 14 is used to collect aluminum chips dropped from the discharge pipe 7. The limiting assembly makes the collecting box 14 detachably connected to the chute to facilitate taking the collecting box 14 out of the chute, and storing the aluminum chips stored in the collecting box 14 separately. A handle may be provided on the side wall of the collecting box 14 to facilitate pulling the collecting box 14.

[0025] like Figure 1 —3, further, the limiting assembly includes: a limiting block 15, the limiting block 15 is L-shaped, one end of the limiting block 15 is fixedly connected to the side wall of the connection box 13, and a clamping block 16 is rotatably provided on the side wall of the collection box 14. When limiting the sliding of the collection box 14, the collection box 14 is pushed to the innermost part of the slide slot, and then the clamping block 16 is rotated so that the free end of the clamping block 16 is clamped into the clamping slot formed between the L-shaped limiting block 15 and the connection box 13, thereby limiting the movement of the collection box 14. When the collection box 14 needs to be taken out, the free end of the clamping block 16 is rotated again to disengage it from the clamping slot between the limiting block 15 and the connection box 13.

[0026] like Figure 1 As shown in FIG. 3 , the apparatus further includes a water pump 17 and a water pipe 18. The inner wall of the discharge pipe 7 is provided with a plurality of spray heads 19. One end of the water pipe 18 is connected to the water pump 17, and the other end of the water pipe 18 is connected to the spray head 19. The bottom of the collection box 14 is provided with a plurality of filter holes. A receiving chamber is provided in the connection box 13, and the receiving chamber is located directly below the collection box 14. When working, the water pump 17 is started, and the water pump 17 supplies water to the spray head 19 through the water pipe 18, so that the spray head 19 sprays water mist into the discharge pipe 7, thereby reducing dust on the aluminum chips falling into the discharge pipe 7. After these aluminum chips fall into the collection box 14, the water attached to them flows into the receiving chamber directly below it through the filter holes, thereby ensuring the purity of the aluminum chips on the collection box 14, which is convenient for subsequent recycling. Specifically, a drain pipe can be provided to discharge the water in the receiving chamber to the outside.

[0027] like Figure 1 As shown in FIG. 2, further, the discharge pipe 7 is tilted toward the direction of the second dust suction pipe 3. The tilted discharge pipe 7 can prevent the aluminum chips from falling into the collection box 14 too quickly after entering the discharge pipe 7, but slide down on the inner wall of the discharge pipe 7, so that the water mist sprayed by the spray head 19 can fully contact with the aluminum chips and absorb the dust attached to the aluminum chips, thereby achieving the purpose of fully cleaning the aluminum chips.

[0028] like Figure 3 As shown, further, a slope is provided on the side wall of the installation frame 2 close to the first dust suction pipe 1. Specifically, the installation frame 2 is a square frame, and a slope is provided on one side of the frame body at the bottom close to the first dust suction pipe 1, so that the aluminum chips shaken off the filter screen plate 6 will slide into the discharge pipe 7 through the slope when they fall, effectively preventing the aluminum chips from accumulating on the frame body at the bottom of the installation frame 2 when they fall.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
