[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] Example 1:

[0031] See also Figure 1-3 , the utility model provides a technical solution: in order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a red mud-based solid waste ventilation and drying equipment, comprising: an equipment main body 1; a sealing door 2 is installed on the front surface of the equipment main body 1; the left and right outer walls of the equipment main body 1 are respectively provided with a first ventilation slot 3 and a second ventilation slot 4; a heat conducting plate 14 is installed on the top of the equipment main body 1, and a heat absorbing film is laid on the top of the heat conducting plate 14; a frame 5 is installed inside the equipment main body 1, and a placement slot 6 is provided inside the frame 5, and a frame 7 is placed in the placement slot 6, and the frame 7 is used to place red mud; a through hole is opened on the outer wall of the frame 5, and a first motor 15 is installed at the bottom of the heat conducting plate 14, and the output end of the first motor 15 is connected to a screw rod 16 with a coupling, and a shaft sleeve 17 is installed on the outer wall of the screw rod 16, and a connecting strip 18 is fixed on the outer wall of the shaft sleeve 17, and a cleaning strip 19 in contact with the heat absorbing film is installed on the connecting strip 18, and a baffle 20 is fixed to the bottom of the heat conducting plate 14.

[0032] Specifically, the present invention installs a heat conducting plate 14 on the top of the device body 1, and a heat absorbing film is laid on the top of the heat conducting plate 14. In summer or when the sun is strong, the heat in the sunlight will be absorbed by the heat absorbing film, and the heat will be conducted to the inside of the device body 1 by the heat absorbing film, thereby achieving the purpose of heating the red mud inside the device body 1.

[0033] Furthermore, by respectively providing a first ventilation slot 3 and a second ventilation slot 4 on the left and right outer walls of the device body 1, the cooperation of the first ventilation slot 3 and the second ventilation slot 4 can improve the permeability of the device body 1, thereby ensuring the ventilation effect of the red mud inside the device body 1, thereby achieving the purpose of ventilating and drying the red mud;

[0034] In summary, compared with the existing ones, the present invention uses renewable resources (solar energy, wind energy) to dry red mud, the overall structure is simpler, and the overall use cost is lower, which can meet the existing needs;

[0035] The utility model starts the first motor 15, and under the action of the first motor 15, the screw rod 16 is driven to work. At this time, the sleeve 17 drives the cleaning bar 19 to move. When the cleaning bar 19 moves, the dust on the surface of the heat absorption film is cleaned, thereby preventing the dust from affecting the heat absorption efficiency of the heat absorption film.

[0036] Example 2:

[0037] See also Figure 1-4 The utility model provides a technical solution: a red mud-based solid waste ventilation and drying equipment, a connecting frame 8 is fixed in the first ventilation slot 3, a second motor 9 is installed on the outer wall of the connecting frame 8, the output end of the second motor 9 passes through the connecting frame 8 and is fixed with a driving rod located inside the connecting frame 8, a first gear 10 is fixed at one end of the driving rod, the inner wall of the connecting frame 8 is rotatably connected to a rotating rod 11, a fan 12 is fixed at one end of the rotating rod 11, a second gear 13 is fixed on the outer wall of the rotating rod 11, the first gear 10 and the second gear 13 are meshed with each other, the diameter of the first gear 10 is larger than the diameter of the second gear 13, a ventilation hole is opened on the outer wall of the connecting frame 8, and the second motor 9 adopts a waterproof design.

[0038] Specifically, the utility model starts the second motor 9, which drives the first gear 10 to rotate through the driving rod. When the first gear 10 rotates, it drives the second gear 13 to rotate. Then, the second gear 13 drives the fan 12 to rotate. Under the action of the fan 12, the outside air enters the interior of the device body 1 through the first ventilation slot 3 and is then discharged through the second ventilation slot 4, thereby promoting the air circulation inside the device body 1 and contributing to the drying effect of the red mud.

[0039] And because the diameter of the first gear 10 is larger than the diameter of the second gear 13, the rotation speed of the second gear 13 is greater than the rotation speed of the first gear 10, so the rotation speed of the fan 12 is faster, further promoting the air circulation inside the equipment body 1 and further improving the drying effect of the red mud.

[0040] Working principle:

[0041] A heat conducting plate 14 is installed on the top of the device body 1, and a heat absorbing film is laid on the top of the heat conducting plate 14. In summer or when the sun is strong, the heat in the sunlight will be absorbed by the heat absorbing film, and the heat will be conducted to the inside of the device body 1 by the heat absorbing film, thereby heating the red mud inside the device body 1.

[0042] Furthermore, by respectively providing a first ventilation slot 3 and a second ventilation slot 4 on the left and right outer walls of the device body 1, the cooperation of the first ventilation slot 3 and the second ventilation slot 4 can improve the permeability of the device body 1, thereby ensuring the ventilation effect of the red mud inside the device body 1, thereby achieving the purpose of ventilating and drying the red mud;

[0043] By starting the first motor 15, the first motor 15 drives the screw rod 16 to work, and the shaft sleeve 17 drives the cleaning bar 19 to move. When the cleaning bar 19 moves, the dust on the surface of the heat absorption film is cleaned, thereby preventing the dust from affecting the heat absorption efficiency of the heat absorption film.

[0044] By starting the second motor 9, the second motor 9 will drive the first gear 10 to rotate through the driving rod. When the first gear 10 rotates, it will drive the second gear 13 to rotate. Then, the second gear 13 will drive the fan 12 to rotate. Under the action of the fan 12, the outside air will enter the interior of the equipment body 1 through the first ventilation slot 3 and then be discharged through the second ventilation slot 4, thereby promoting the air circulation inside the equipment body 1 and contributing to the drying effect of the red mud.

[0045] And because the diameter of the first gear 10 is larger than the diameter of the second gear 13, the rotation speed of the second gear 13 is greater than the rotation speed of the first gear 10, so the rotation speed of the fan 12 is faster, further promoting the air circulation inside the equipment body 1 and further improving the drying effect of the red mud.
