Description

Technical Field

[0001] The utility model relates to the technical field of hazardous solid waste mixing, in particular to a solid hazardous waste mixing device. Background Art

[0002] Solid hazardous wastes are generally corrosive, toxic, flammable, reactive or infectious, and pose a great threat to the environment and human health. Usually, sintering materials prepared with solid waste, coal and return powder in a certain proportion are placed in the feed hopper by a crane grab, and the solid hazardous wastes are mixed by a mixing device. When cleaning the inside of the mixing device, it is generally done manually, which greatly increases the labor intensity of the workers and reduces the mixing efficiency. In order to solve the above problems, in the application number: CN201821898852.7, A technical solution is disclosed, but the technical solution still has some problems when it is used. The technical solution uses liquid for cleaning when processing the inside of the equipment, but in actual use, effective solid waste cannot be cleaned with water, and a large amount of waste liquid is easily generated, which leads to secondary pollution. In addition, the equipment cannot crush the solid waste when mixing it, which may cause the solid waste to be larger in volume, thereby affecting the mixing efficiency. During the mixing process, the equipment only stirs in one direction, which may cause the equipment to be not uniform during mixing, thereby reducing the practicability and ease of use of the equipment.

[0003] Based on this, the utility model designs a solid hazardous waste mixing device to solve the above problems. Utility Model Content

[0030] Working principle:

[0031] During operation, the solid waste to be mixed is placed in the hopper 3, and then the telescopic rod 21 is controlled to be shortened. At this time, the block 22 on the telescopic rod 21 is engaged with the worm 19, and then the driving motor 20 is controlled to work. When the driving motor 20 is working, the telescopic rod 21 controls the worm 19 to rotate, and then the worm 19 drives the worm gear 6 to rotate. When the worm gear 6 rotates, the worm gear 6 controls the driving shaft 4 to rotate.

When the driving shaft 4 rotates, the driving shaft 4 simultaneously controls the rotating column 11 to rotate. When the rotating column 11 rotates, the gear 12 installed at one end of the rotating column 11 drives the two toothed discs 10 to rotate. When the toothed discs 10 rotate, since the gear 12 is located between the two toothed discs 10, the rotation of the two toothed discs 10 The direction of movement is opposite to that of the stirring shaft 8, so that the stirring on the stirring shaft 8 is stirred in different directions, so that the equipment is more uniform during mixing, and the equipment is prevented from stirring in the same direction during mixing, which leads to a decrease in the mixing efficiency of the equipment. When the equipment is mixed, the telescopic rod 21 is controlled to extend, and the telescopic rod 21 and the threaded rod 16 are connected. At this time, the driving motor 20 controls the threaded rod 16 to rotate, and then the cleaning plate 15 threadedly connected on the threaded rod 16 moves downward along the guide rod 14, so that the impurities remaining on the inner wall of the mixing box 1 can be cleaned to the lower side of the mixing box 1, thereby avoiding a large amount of impurities remaining in the mixing box 1, and avoiding manual cleaning at the same time, and no need to use liquid for cleaning, further avoiding the secondary pollution of impurities caused by the reaction between liquid and impurities, and further improving the practicability and convenience of use of the equipment.
