[0023] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention.

[0024] It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details.

[0025] In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0026] like Figure 1-Figure 4 As shown, a waste powder dust removal device for an asphalt mixing station is composed of a mixing station body 1, an air delivery pipe 2, a card plate 3, a catalyst 4, an exhaust pipe 5, an exhaust fan 6, a spray device 7, a water baffle 8, a water receiving tray 9, a slide seat 10, a handle 11, a slide rail 12, a water outlet 13, a water storage tank 14, an air duct 15, a control motor 16, a rotary plate 17, a spray rack 18, an adsorption plate 19, a spray head 20, a rack plate 21, and a filter screen 22.

[0027] like Figure 1-Figure 4 As shown, the mixing station body 1 works and generates a large amount of dust, which is sent to the catalyst 4 through the air pipe 2. In order to ensure the stability of the placement of the air pipe 2, the air pipe 2 is fixed by multiple clamping plates 3. The catalyst 4 adopts UV photocatalysis. The UV photocatalysis combines ultraviolet light with iron ions to accelerate the decomposition of H2O2, and oxidize and remove some components contained in the dust; the dust after the first step of purification is sent to the exhaust pipe 5 through the exhaust fan 6, and the exhaust pipe 5 is equipped with a spray head 20. The solid impurities contained in the dust are removed by mixing water with the dust. The impurities finally fall into the water receiving tray 9, and the excess gas is discharged through the exhaust pipe 5.

[0028] The spray device 7 includes a rotary plate 17, a plurality of air passages 15 are opened in the middle of the rotary plate 17, an annular groove is opened around it, a rack plate 21 is installed in the annular groove, and a control motor 16 is installed above the rotary plate 17. The output end of the control motor 16 is toothed and can be meshed with the rack plate 21 for transmission, thereby driving the rotary plate 17 to rotate. The rotary plate 17 is in rotational cooperation with the spray frame 18.

[0029] A plurality of spray heads 20 are installed at the bottom of the spray rack 18. The plurality of spray heads 20 work simultaneously, covering a wider area and having a better dust settling effect. Adsorption plates 19 are installed at the bottom of both sides of the spray rack 18. The adsorption plates 19 contain activated carbon, which purifies the dust and discharges it through the air duct 15 after purification.

[0030] When exhaust is not needed, the rotary plate 17 and the air passage 15 of the spray rack 18 are misaligned, and the gas cannot be discharged. After purification for a period of time, the control motor 16 drives the rotary plate 17 to rotate, the air passage 15 is connected, and the gas is discharged.

[0031] A filter screen 22 is installed on the air passage 15 on the rotating plate 17 to prevent impurities from falling from the exhaust hole opened at the top of the exhaust pipe 5, and large impurities from falling into the exhaust pipe 5, causing the exhaust pipe 5 to be blocked.

[0032] The bottom of the water receiving tray 9 is provided with a hole which is communicated with the water storage tank 14 , and the water can be stored in the water storage tank 14 after being received.

[0033] The working principle of this utility is as follows:

[0034] When the mixing station is working, a large amount of dust will be generated when collecting waste powder. The dust is sucked into the air pipe 2 by the exhaust fan 6, and after the first step of decomposition by the catalyst 4, it enters the exhaust pipe 5. The spray head 20 in the exhaust pipe 5 works, and the impurities in the dust combine with liquid water, settle downward and fall into the water retaining channel, and finally fall into the water receiving tray 9. The water receiving tray 9 is connected with the water storage tank 14, and finally the excess water enters the water storage tank 14 for collection. When a certain amount is collected, it can be discharged through the water outlet 13. When the water receiving tray 9 needs to be cleaned, the handle 11 is pulled to take out the water receiving tray 9 to complete the cleaning; and the excess air is adsorbed by a certain amount of impurities through the adsorption plate 19, and the cleaned air is discharged from the exhaust pipe 5 through the air duct 15. When the air is purified, the control motor 16 controls the rotary plate 17 to rotate, and the air duct 15 is not connected and cannot be discharged. After the purification is completed, the rotary plate 17 is controlled to rotate again, and the air duct 15 is connected to complete the exhaust.

[0035] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical scheme of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
