[0002] The cement industry has a natural advantage in solid waste treatment and is one of the future development directions of solid waste treatment. The calcination of solid waste in a rotary kiln can not only partially replace raw fuel materials and reduce the consumption of natural resources, but also effectively eliminate harmful substances in the solid waste under the high-temperature calcination state in the rotary kiln, which will cause damage to the environment.

[0003] For example, the "Rotary Kiln Dust Collection Device for Solid Waste Recovery" with publication number CN212396262U includes a rotary kiln; the rotary kiln is connected to a first flue gas pipe, the rotary kiln is connected to a settling chamber through the first flue gas pipe, the settling chamber is connected to a second flue gas pipe, and the settling chamber is connected to a bag filter through the second flue gas pipe; the end of the first flue gas pipe is evenly connected to a first branch pipe, and the air inlet end of the second flue gas pipe is evenly connected to the second branch pipe; partitions are evenly arranged in the settling chamber, the partitions divide the settling chamber into ventilation channels, the partitions are arranged as a cavity structure, the partitions are inclined, the top plate of the partitions is a mesh structure, air outlets are evenly opened on one side of the ventilation channel, the air outlet is connected to a second branch pipe, a filter is arranged at the air outlet, and one end of the partition is connected to the first branch pipe. The problem of dust removal is not easy in the flue gas burned in the rotary kiln.

[0004] Although the above-mentioned rotary kiln has certain advantages in treating the flue gas generated by solid waste, it still has certain disadvantages:

[0005] When using a rotary kiln to recycle solid waste, the hot melting of the solid waste by the rotary kiln will not only produce smoke, but also leave residues. The residues need to be transported out for treatment. The scattered residues are easy to fall during transportation, and dust is easily generated. It is also dangerous and affects the transportation efficiency. Utility Model Content

Through this arrangement, when the cylinder 7811 drives the adjusting rod 7810 to move, it can drive the sliding block 788 to move.

[0027] Here’s how it works:

[0028] First, when in use, solid waste is introduced into the rotary kiln body 2, where it is pyrolyzed and melted under the high temperature environment in the kiln, and then reaches the discharge box 3, where the generated gas passes through the flue gas pipeline 4 to the waste heat recovery device 5 for energy recovery, and then passes through the flue gas pipeline 4 to the purification tower 6 for purification and discharge, and the residue of the solid waste falls from the bottom of the discharge box 3;

[0029] Second, the residue of the fixed waste falls from the bottom of the discharge box 3 onto the guide plate 71, and enters the extrusion box 72 through the guide plate 71. The amount of residue in the extrusion box 72 is detected by the laser sensor 76. When there are too many residues, the hydraulic cylinder 74 is started, and the hydraulic cylinder 74 pushes the pressing plate 75 to pressurize the residue to form a block;

[0030] Third, start the cylinder 7811, and drive the adjusting rod 7810 to move upward through the cylinder 7811. When the adjusting rod 7810 moves, it drives the sliding block 788 to move, so that the sliding block 788 moves along the sliding groove 789. When the sliding block 788 moves, it drives the hinge 2 786 to move through the connecting rod 787. When the hinge 2 786 moves, it drives the adjusting block 784 to rotate, so that the adjusting block 784 rotates along the hinge 1 785. When the adjusting block 784 rotates, it drives the fixed block 783 to rotate. When the fixed block 783 rotates, it drives the opening and closing plate 782 to rotate, so that the opening and closing plate 782 no longer closes the adjusting groove 781.

[0031] Fourth, start the second hydraulic cylinder 774, and push the push block 772 to move through the second hydraulic cylinder 774. When the push block 772 moves, it pushes the residue block to move, and pushes the residue block out of the extrusion box 72, so as to complete the extrusion of the residue and facilitate its transportation.

[0032] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.
