The liquid inlet and air inlet member can be switched between the first state and the second state.

[0026] The dust removal device of this utility model includes a spraying component 100 and a liquid and air inlet component. The spraying component 100 is oscillating around a preset axis so that the spray outlet 102 of the spraying component 100 faces the plate to be cleaned 1. Then, the liquid and air inlet component switches to a second state, so that the high-pressure gas sprayed from the spray outlet 102 removes the dust on the plate to be cleaned 1. Then, the liquid and air inlet component switches to a first state, so that the liquid sprayed from the spray outlet 102 cleans the plate to be cleaned 1. Then, the liquid and air inlet component switches to a second state, so that the high-pressure gas sprayed from the spray outlet 102 removes the liquid on the plate to be cleaned 1. Thus, the plate to be cleaned 1 is thoroughly cleaned, ensuring the cleanliness of the plate to be cleaned 1 and preventing the sample from being contaminated with dust. This solves the problem in the prior art that glass plates are easily contaminated with coal ash, leading to inaccurate test results.

[0027] Specifically, the liquid introduced into the first connection port can be clean water; the surface of the plate to be cleaned 1 is coated with a hydrophobic film for waterproofing; the plate to be cleaned 1 is a glass plate.

[0031] Specifically, the connection between the first cylinder 300 and the liquid and air inlet is made more stable by connecting the second axial end of the first cylinder 300 to the liquid and air inlet. At the same time, the connection between the first cylinder 300 and the liquid and air inlet is made more stable by connecting the first axial end of the first cylinder 300 to the liquid and air inlet. This ensures that the first cylinder 300 can drive the liquid and air inlet to swing. The preset axis is the axis of the first cylinder.

[0032] In this embodiment, a first connecting pipe 304 is provided inside the first cylinder 300, and a second connecting pipe 400 is provided inside the ejector 100. The two ends of the first connecting pipe 304 are respectively connected to the third connecting port and the first end of the second connecting pipe 400. The inner cavity of the second connecting pipe 400 is connected to the ejector outlet 102 of the ejector 100.

[0033] Specifically, the first connecting pipe 304 and the second connecting pipe 400 are connected to make the third connecting port and the nozzle 102 connected, so that liquid or gas can be transferred from the liquid inlet and gas inlet to the nozzle 100.

The first cylinder 300 and the mounting component 500 are rotatably connected. The first cylinder 300 and the spraying component 100 are located on both sides of the mounting base surface 501, respectively.

[0035] Specifically, the mounting component 500 is used to fix the dust removal device to the mounting base surface 501 where the plate to be cleaned 1 is located. The first cylinder 300 and the mounting component 500 are rotatably connected, ensuring that the spraying component 100 can swing relative to the mounting base surface 501.

The axis of the first cylinder 300 and the axis of the second cylinder 600 are arranged to coincide. The second cylinder 600 and the mounting member 500 are fixedly connected.

[0037] Specifically, the second cylinder 600 is used to connect the mounting component 500 and the mounting base, so that the first cylinder 300 and the mounting component 500 are rotatably connected, ensuring that the ejector 100 can swing relative to the mounting base 501, further enhancing the structural stability of the dust removal device.

[0038] In this embodiment, the dust removal device also includes a bearing 700, the outer ring of which is connected to the inner wall of the second cylinder 600, and the inner ring of which is connected to the outer wall of the first cylinder 300.

[0039] Specifically, by setting the outer ring of bearing 700 to be connected to the inner wall of the second cylinder 600 and the inner ring of bearing 700 to be connected to the outer wall of the first cylinder 300, the first cylinder 300 can be rotatably connected to the second cylinder 600. The addition of bearing 700 makes the rotation of the first cylinder 300 smoother, reduces friction and wear, and extends the service life of the dust removal device.

[0040] In this embodiment, the dust removal device further includes a connecting ring 800, which is sleeved on the outer circumferential side of the second cylinder 600. Along the circumferential direction of the connecting ring 800, a plurality of first through holes are provided at intervals on the connecting ring 800, and a second fastening hole corresponding to the first through holes is provided on the mounting member 500. The fastener 802 passes through the first through holes and the second fastening holes to securely connect the connecting ring 800 and the mounting member 500.

[0041] Specifically, by using fasteners 802 through the first through hole and the second fastening hole, the connecting ring 800 and the mounting part 500 are securely connected, which strengthens the connection reliability between the second cylinder 600 and the mounting part 500, thereby ensuring the connection reliability between the dust removal device and the mounting base 501 where the plate to be cleaned 1 is located. This connection structure not only ensures the stable installation of the dust removal device, but also facilitates the disassembly and maintenance of the dust removal device.

[0042] In this embodiment, the dust removal device further includes a third cylinder 900 and a driving member 902. The driving member 902 and the third cylinder 900 are drivenly connected. The third cylinder 900 and the first cylinder 300 are drivenly connected through a transmission structure, so that the driving member 902 drives the third cylinder 900 to rotate around the axis of the third cylinder 900, thereby driving the first cylinder 300 to rotate.

[0043] Specifically, the third cylinder 900 is driven to rotate by the driving component 902, which in turn drives the first cylinder 300 to rotate, ensuring that the nozzle 102 of the ejector 100 can face the plate to be cleaned 1.

[0044] Optionally, the drive unit 902 is a swing cylinder or a motor.

[0045] In this embodiment, the transmission structure includes two transmission rings 10 and a transmission belt 13. The two transmission rings 10 are respectively sleeved on the first cylinder 300 and the third cylinder 900, and the transmission belt 13 is sleeved on the circumferential sidewalls of the two transmission rings 10.

[0046] Specifically, through the cooperation of the transmission belt 13 and the two transmission rings 10, the power of the drive component 902 is smoothly transmitted to the first cylinder 300, thereby driving the ejector component 100 to oscillate. This transmission structure not only simplifies the power transmission path but also improves transmission efficiency, making the oscillation of the ejector component 100 more flexible and better adaptable to cleaning plates 1 of different shapes and sizes, thus improving the comprehensiveness and efficiency of the dust removal device.

[0048] The dust removal device of this utility model includes a spraying component 100 and a liquid and air inlet component. The spraying component 100 is oscillating around a preset axis so that the spray outlet 102 of the spraying component 100 faces the plate to be cleaned 1. Then, the liquid and air inlet component switches to a second state, so that the high-pressure gas sprayed from the spray outlet 102 removes the dust on the plate to be cleaned 1. Then, the liquid and air inlet component switches to a first state, so that the liquid sprayed from the spray outlet 102 cleans the plate to be cleaned 1. Then, the liquid and air inlet component switches to a second state, so that the high-pressure gas sprayed from the spray outlet 102 removes the liquid on the plate to be cleaned 1. Thus, the plate to be cleaned 1 is thoroughly cleaned, ensuring the cleanliness of the plate to be cleaned 1 and preventing the sample from being contaminated with dust. This solves the problem in the prior art that glass plates are easily contaminated with coal ash, leading to inaccurate test results.

[0049] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
