Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] This utility model provides a dust filter box. Please refer to [link / reference]. Figure 1-2 It includes a box body consisting of an outer sleeve 1 and an inner sleeve 3. The outer sleeve 1 and the inner sleeve 3 are slidably sealed together. A first filter plate 12 is provided in the inner cavity of the outer sleeve 1. A discharge port 11 is provided at the bottom of the outer sleeve 1. The end of the inner sleeve 3 away from the outer sleeve 1 is an air inlet. The end of the outer sleeve 1 away from the inner sleeve 3 has an air outlet 2.

[0029] The right end of the inner sleeve 3 extends into the outer sleeve 1, and a first sealing ring 9 and a second sealing ring 10 are fitted on the outer sleeve 1. The second sealing ring 10 is bonded to the inner sleeve 3, and the first sealing ring 9 is bonded to the outer sleeve 1. Figure 2 As shown, the air entering from the left side of the inner sleeve 3 passes through the first filter plate 12 and is discharged through the air outlet 2. The dust is blocked by the first filter plate 12 between the first filter plate 12 and the right end of the inner sleeve 3.

[0030] A support block 13 is welded to the inner wall of the outer sleeve 1, and the first filter plate 12 and the support block 13 are fixed together by bolts.

[0031] An upright rod 4 is welded onto the inner sleeve 3. An electric telescopic rod 5 is installed between the upright rod 4 and the outer sleeve 1. Specifically, a first support connecting seat 7 is welded onto the upright rod 4. The electric telescopic rod 5 is inserted into the inner wall of the first support connecting seat 7 and is fixed to the first support connecting seat 7 with bolts. A second support connecting seat 8 is welded onto the outer wall of the outer sleeve 1. The electric telescopic rod 5 is inserted into the inner wall of the second support connecting seat 8 and is fixed to the second support connecting seat 8 with bolts. When the electric telescopic rod 5 extends, it can move the inner sleeve 3 away from the outer sleeve 1, so that the second sealing ring 10 and the right end of the inner sleeve 3 are located to the left of the discharge port 11, so that the dust at the first filter plate 12 inside the outer sleeve 1 can be discharged from the discharge port 11.

[0032] In practical use:

[0033] Air enters the inner sleeve 3 through the left end of the inner sleeve 3, and then enters the outer sleeve 1. The air passes through the first filter plate 12, and the dust is filtered by the first filter plate 12 and retained at the first filter plate 12.

[0034] When cleaning the dust inside the outer sleeve 1, the electric telescopic rod 5 extends and can move the inner sleeve 3 away from the outer sleeve 1, so that the second sealing ring 10 and the right end of the inner sleeve 3 are located on the left side of the discharge port 11, so that the dust at the first filter plate 12 inside the outer sleeve 1 can be discharged from the discharge port 11; then the electric telescopic rod 5 drives the inner sleeve 3 and the second sealing ring 10 to reset.

[0035] Example 2:

[0036] See attached document Figure 3-5 Unlike Embodiment 1, the outer sleeve 1 has a through hole 21 and a limiting seat 22 is welded to the bottom of the outer sleeve 1. The first filter plate 12 is replaced with a second filter plate 16. The second filter plate 16 passes through the through hole 21 and is inserted into the limiting seat 22. The limiting seat 22 is a hollow structure with an open top. A rubber ring 161 is fitted on the second filter plate 16. The rubber ring 161 is in close contact with the inner wall of the outer sleeve 1 and the inner wall of the through hole 21. The vibrator 14 drives the second filter plate 16 to vibrate, thereby causing the second filter plate 16 to vibrate and shake off the dust on the second filter plate 16, ensuring the air permeability of the second filter plate 16.

[0037] A lifting plate 162 is welded onto the second filter plate 16. A vibrator 14 is installed between the lifting plate 162 and the outer sleeve 1. The lifting plate 162 is slidably connected to the guide rod 15, and the bottom of the guide rod 15 is welded to the outer sleeve 1. The end of the inner sleeve 3 away from the outer sleeve 1 is connected to the air inlet pipe, and the end of the outer sleeve 1 away from the inner sleeve 3 is connected to the input end of the air pump 17. This ensures that the second filter plate 16 will not move out of the limiting seat 22 during vibration.

[0038] A dust filtration device, please refer to Figure 6 It also includes an air pump 17 that is connected to the air outlet 2. The air pump 17 is mounted on the bracket 18, and a third support connecting seat 6 is welded to the bottom of the outer sleeve 1. A support column 19 is inserted into the inner wall of the third support connecting seat 6, and the third support connecting seat 6 and the support column 19 are fixed together by bolts. The bottom of the support column 19 is welded to the bracket 18. A caster wheel is installed at the bottom of the bracket 18, and a threaded rod 20 is threadedly connected to the bracket 18. A contact plate 201 is welded to the bottom of the threaded rod 20. The contact plate 201 is driven to contact the ground by turning the threaded rod 20 to limit the movement of the device.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
