[0032] As Figure 1 shown, the dust cleaning device of this embodiment includes a material pushing mechanism 1 and a material collecting mechanism 2. The material pushing mechanism 1 includes a moving rod 11 and a material pushing member 12. The material pushing member 12 is located inside the kiln and abuts against the bottom wall of the kiln. One end of the moving rod 11 is connected to the material pushing member 12, and the other end of the moving rod 11 penetrates and extends out of the side wall of the kiln. The material collecting mechanism 2 includes a blanking pipe 21 and a guiding pipe 22. The blanking pipe 21 penetrates through the bottom wall of the kiln and communicates with the inside of the kiln, and the guiding pipe 22 is communicated with the bottom of the blanking pipe 21.

[0033] A dust cleaning device provided by the utility model comprises a material pushing mechanism 1 and a material receiving mechanism 2. The material pushing mechanism 1 includes a moving rod 11 and a material pushing member 12. One end of the moving rod 11 is located outside the kiln, and the other end is located inside the kiln and is connected to the material pushing member 12. The material pushing member 12 abuts against the bottom wall of the kiln. When the cleaner pushes the extending end of the moving rod 11, the material pushing member 12 can move on the bottom wall of the kiln, so as to push the dust accumulated on the bottom wall of the kiln. The material receiving mechanism 2 includes a blanking pipe 21 penetrating through the bottom wall of the kiln and a guide pipe 22 connected to the bottom of the blanking pipe 21. When the material pushing member 12 pushes the dust, the dust will fall into the blanking pipe 21 and is collected through the guide pipe 22, thus completing the cleaning of the dust inside the kiln. This dust cleaning device can clean the dust without stopping the furnace for cooling, avoiding the shutdown and restart of the kiln, reducing the operation intensity of employees, shortening the maintenance time, saving energy consumption and increasing the production capacity. During cleaning, since the dust is led out from the bottom wall of the kiln by the material receiving mechanism 2, the high-temperature gas overflowing inside and outside the kiln is reduced, the temperature rise around the kiln is lowered, and the flying and diffusion of dust can be reduced, which is beneficial to improving the working environment of the cleaner.

[0037] Optionally, the dust cleaning device further includes a driving mechanism (not shown in the figure), the output end of the driving mechanism is connected to the moving rod 11, and is used to drive the movement of the moving rod 11. In some embodiments, the driving mechanism is a driving motor, and the moving rod 11 is a lead screw structure; in some other embodiments, the driving mechanism can be a cylinder, a hydraulic cylinder, etc.

[0038] Further, the cross-section of the blanking pipe 21 gradually increases from bottom to top, expanding the opening of the blanking pipe 21 to facilitate the falling of dust.

[0039] Optionally, the dust cleaning device includes a plurality of material receiving mechanisms 2. The blanking pipes 21 of the plurality of material receiving mechanisms 2 are arranged at intervals on the bottom wall of the kiln furnace. A plurality of pushing members 12 are arranged in one-to-one correspondence with the plurality of blanking pipes 21, thereby reducing the moving distance of the moving rod 11 and improving the efficiency of dust cleaning. Exemplarily, there are two, three, four, etc. material receiving mechanisms 2.

[0040] In this embodiment, the outlet of the guide pipe 22 extends towards the side of the kiln furnace, facilitating the collection of dust in the guide pipe 22. Optionally, the outlet of the guide pipe 22 can be horizontally arranged, or can be inclined downward. The outlet of the guide pipe 22 can also face different sides of the kiln furnace, expanding the working space and improving the convenience of cleaning.

[0041] In order to improve the efficiency of collecting dust in the guide pipe 22, the outlet of the guide pipe 22 can also be externally connected to a dust suction device to suck the dust out of the guide pipe 22, which is beneficial to improving the dust collection efficiency and reducing the working intensity of the staff.

[0042] Further, the material receiving mechanism 2 further includes a material receiving member 24, and the material receiving member 24 is arranged below the outlet of the guide pipe 22 to prevent a small amount of dust from falling at the outlet of the guide pipe 22 and polluting the surrounding working environment.
