[0023] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0024] Example 1

[0025] like Figures 1 to 4 As shown, an embodiment of the present invention provides a dust filtering structure, comprising a filter component 1 and a filter component 2;

[0026] The filter assembly 1 includes a box body 1 and a filter structure 2 disposed in the box body 1;

[0027] The second filter assembly includes a second box body 3 and a second filter structure 4 disposed in the second box body 3;

[0028] Among them, both box body 1 and box body 2 3 have an air inlet and an air outlet. The air inlet of box body 2 3 is connected to the air outlet of box body 1 through a pipe 5; the filter structure 1 2 is located between the air inlet and air outlet of box body 1.

[0029] The filter structure 1-2 of this embodiment is a herringbone filter screen. A fixing structure for fixing the filter structure 1-2 is provided in the box body 1. The fixing structure includes a square frame-shaped support plate 7 and a square frame-shaped pressure plate 8. The top of the filter structure 1-2 has a folded edge and is placed between the square frame-shaped support plate 7 and the square frame-shaped pressure plate 8. The frame-shaped support plate 7 and the frame-shaped pressure plate 8 can be fixed together by bolts or buckles.

[0030] The second filter structure 4 of this embodiment includes a connecting pipe 6 and a dust adsorption box located within the second box 3. One end of the connecting pipe 6 is connected to the air inlet of the second box 3, and the other end is located within the dust adsorption box. The air outlet is located at the top of the second box 3. To reduce costs, the dust adsorption box is a water tank. The water can be submerged in the pipe opening of the connecting pipe 6 to adsorb dust into the water.

[0031] In order to further improve the dust filtering effect, a dust filter can be provided in the pipe 5;

[0032] Working principle: The dust-containing air of the dust collection system first enters the box body 1 through the air inlet of the box body 1. The air can enter the pipe 5 from the air outlet only after passing through the filter structure 2. This is the first-level filtration. The air is filtered through the dust filter in the pipe 5. This is the second-level filtration. The air enters the connecting pipe 6 through the air inlet of the box body 2 3, enters the water through the connecting pipe 6, and is adsorbed in the water. This is the third-level filtration. The clean air after filtering is discharged from the air outlet of the box body 2 3.

[0033] Example 2

[0034] like Figure 1 As shown, this embodiment provides a dust collection system, including the above-mentioned dust filtering structure, and also includes a fan 10, a dust collection disc 11, a filter bin 12 and a dust box 13. The filter bin 12 is connected to the dust collection disc 11 and the fan 10 respectively. A filtering structure is provided in the filter bin 12. The bottom of the filter bin 12 has a dust discharge port. The dust box 13 is located at the dust discharge port. The air inlet of the dust filtering structure box 1 is connected to the air outlet of the fan 10.

[0035] Box 1 1 and box 2 3 are located on both sides of the dust box 13, and the duct 5 is located on the top of the dust box 13;

[0036] At least one level of filtering structure is provided in the filter chamber 12, and together with the three-level filtering of the dust filtering structure, it has at least a four-level filtering function, thereby effectively preventing the discharge of dusty air. In addition, the filter mesh used in the multi-stage filtering assembly can have gradually decreasing filter holes. For example, the filter mesh of the herringbone filter mesh is larger than the filter mesh of the dust filter mesh in the pipe 5, thereby filtering out large particles of dust and small particles of dust in turn, and preventing the occurrence of excessive accumulation of dust in one place.

[0037] Specifically, the filter assembly in the filter chamber 12 includes a primary filter structure and a secondary filter structure. The primary filter assembly is located on one side of the dust inlet of the filter chamber 12, and the secondary filter assembly is located above the primary filter assembly. The air intake of the fan 10 is connected to the secondary filter assembly.

[0038] The primary filter assembly includes a rotating shaft rotatably disposed in the filter chamber 12, a plurality of filter blades mounted on the rotating shaft, and a motor 1 for driving the rotating shaft to rotate; the plurality of filter blades are evenly fixed on the rotating shaft along the circumference; the filter blades are located at the dust outlet and can send dust and garbage into the dust box 13;

[0039] The secondary filter assembly includes at least one cylindrical filter element installed in the filter chamber 12, and the air intake of the fan 10 is connected to the internal space of the cylindrical filter element;

[0040] One end of the filter element is closed and the other end has an opening;

[0041] This embodiment takes two filter elements as an example. The internal spaces of the two filter elements are connected to a relay box, and the relay box is connected to the air intake of the fan 10. That is, the air is filtered by the filter elements before entering the fan 10, which can reduce the impact of dust on the service life of the fan 10.

[0042] In order to clean the dust accumulated on the filter element and maintain a good filtering effect, a cleaning component is further provided in the filter chamber 12, which includes a dust hopper and a dust discharge pipe; one end of the dust discharge pipe is connected to the lower end of the dust hopper, and the other end passes through the filter chamber 12 and is located above the dust box 13. The dust hopper is located on the lower side of the filter element, and one side of the dust hopper can directly contact the filter element. A brush or scraper can also be installed on one side of the dust hopper. During the rotation of the filter element, the dust on the filter element is scraped into the dust hopper and enters the dust box 13 along the dust discharge pipe;

[0043] Working principle: Under the action of the fan 10, dust and garbage are sucked from the dust collection disk 11 and enter the filter bin 12 through the pipeline. The filter blades in the filter bin 12 send the garbage and part of the dust into the dust box 13 (primary filtration). Another part of the air containing dust enters the filter element, and some dust is adsorbed on the outside of the filter element (secondary filtration). Some small particles of dust mixed with air pass through the filter element and the fan 10 and enter the box 1. After being filtered by the herringbone filter (third-stage filtration), they enter the box 2 3. Finally, the remaining dust is discharged into the water in the box 2 3 (fourth-stage filtration). The purified air is discharged through the air outlet on the top of the box 2 3.

[0044] After the above four-stage filtration, secondary pollution of the air can be effectively avoided.

[0045] Example 3

[0046] like Figure 1 As shown, this embodiment provides a sanitation vehicle, comprising the above-mentioned dust collection system, which is installed on the chassis 14 of the sanitation vehicle.
