It is set slightly tilted from the horizontal, and while slowly rotating, the waste supplied from the top is transferred to the bottom, and air is supplied from the front or back in equal amounts to make it burn. At present, the rotary kiln incinerator burns solid waste by direct input or chain conveyor, but there may be a large amount of liquid waste on the solid waste.

[0032] The working principle of the present invention is specifically described as follows:

[0033] In this design, when the hazardous waste rotary kiln incineration feeding device is working, the motor 201 is first started, and then the solid material is poured from the hopper 104 into the first shell 101. After the solid material enters the first shell 101, it falls into the connecting column 402;

[0034] When the motor 201 is started, its power output shaft drives the first transmission shaft 202 connected thereto to rotate, and the first transmission shaft 202 rotates and drives the first gear 203 coaxial therewith to rotate, and the first gear 203 rotates and drives the second gear 204 meshing therewith to rotate, and the second gear 204 rotates and drives the second transmission shaft 205 above it to rotate, and the second transmission shaft 205 rotates and drives the two scrapers 206 connected to its periphery to rotate;

[0035] After the two scrapers 206 rotate, they push the solid materials that fall into the connecting column 402 to rotate around the central axis of the second transmission shaft 205. After the solid materials rotate, the liquid on their surface is thrown off to the inner wall of the connecting column 402 under the action of centrifugal force. The thrown liquid slides down along the annular opening 403 and finally falls below the support plate 401, thereby achieving solid-liquid separation.

[0036] In this design, when the hazardous waste rotary kiln incineration feeding device does not start working, the electric telescopic rod 506 is in an extended state, driving the movable plate 504 to move downward through the connecting plate 505, and the movable plate 504 passes through the slide groove 502 and extends into the groove 503. At this time, the discharge groove 501 is in a closed state;

[0037] In the present design, the motor 201 and the electric telescopic rod 506 are both connected to the PLC, and can be set. When the power output shaft of the motor 201 rotates the rated number of times, the electric telescopic rod 506 moves upward, driving the movable plate 504 to open the closed discharge trough 501; at this time, the second transmission shaft 205 continues to rotate, pushing the solid-liquid separated material in the connecting column 402 into the feed frame 304, and the material falls into the U-shaped groove 301 through the feed frame 304. When the power output shaft of the motor 201 rotates the rated number of times again, the telescopic rod 506 moves downward, and the discharge trough 501 is closed again;

[0038] When the first transmission shaft 202 rotates, the blade shaft 305 connected thereto is driven to rotate. After the blade shaft 305 rotates, the shaftless spiral blade 303 is driven to rotate. After the shaftless spiral blade 303 rotates, the material in the U-shaped groove 301 is pushed into the connecting frame 106 and finally introduced into the rotary kiln.

[0039] In this design, the side cleaning door 103 is designed to facilitate the subsequent cleaning of liquid waste accumulated in the first shell 101, and the upper cleaning door 105 set above the second shell 102 is convenient for cleaning the inside of the second shell 102 and the U-shaped groove 301.
