The ball screw 20 is fixedly connected to the output end of the third motor 21. The third motor 21 is fixedly connected to the outer wall of the dust-removing housing 14. A moving block 22 is threadedly connected to the ball screw 20, and a soft brush 23 is fixedly connected to the upper surface of the moving block 22;

[0106] A collection box 24, which is fixedly connected to the inner wall of the bottom surface of the filtration chamber 1401. The upper end of the collection box 24 is open;

[0107] A water tank 25, which is fixedly connected to the inner wall of the bottom surface of the sedimentation chamber 1402. Clear water is contained in the water tank 25;

[0108] An air delivery pipe 26. One end of the air delivery pipe 26 penetrates through the third partition plate 15 and communicates with the upper part of the filtration chamber 1401. The other end of the air delivery pipe 26 penetrates through the outer wall of the water tank 25 and is inserted below the water surface. A second blower 2601 is connected to the air delivery pipe 26;

[0109] An air delivery pipe 27. One end of the air delivery pipe 27 penetrates through the outer wall of the water tank 25 and is located above the water surface. The other end of the air delivery pipe 27 penetrates through the fourth partition plate 16 and communicates with the drying chamber 1403;

[0110] A support frame 28, which is fixedly connected to the inner wall of the drying chamber 1403. A plurality of heating tubes 29 are fixedly connected to the support frame 28;

[0111] An air outlet pipe 30. One end of the air outlet pipe 30 communicates with the drying chamber 1403.

[0112] The working principle and beneficial effects of the above technical solution are as follows: The air containing floating dust in the conical barrel 202 is sucked into the filtering cavity 1401 through the air inlet pipe 17. The floating dust in the air is preliminarily filtered by the ventilation membrane 19, so that the floating dust with larger size falls into the collection box 24. After the floating dust is collected, it is uniformly processed to protect the cleanliness of the production environment. As the ball screw 20 rotates, the moving block 22 moves left and right on the ball screw 20, driving the soft brush 23 to brush the ventilation membrane 19, so that the dust adhered to the ventilation membrane 19 falls off, preventing too much dust from adhering to the ventilation membrane 19 and affecting the passage of air, and improving the working efficiency of the dust reduction device 13. The filtered air is pumped into the water tank 25 by the first air delivery pipe 26. The tiny dust settles in the water, and the clean air floats on the water surface and enters the drying cavity 1403 through the second air delivery pipe 27. After being dried in the drying cavity 1403, the clean air is pumped into the housing 1 by the air outlet pipe 30, ensuring the cleanliness of the air inside the production device, drying the clean air, and can also be used to dry the regenerated material inside the conical barrel 202, preventing the damp air from affecting the dryness of the regenerated resources and the quality of the dry-mixed mortar produced. The floating dust inside the production device is cleaned, preventing the production device from malfunctioning due to excessive floating dust, improving the service life of the production device, and at the same time improving the cleanliness of the working environment of the production personnel, preventing the production personnel from inhaling the floating dust and damaging their health, and ensuring the physical health of the production personnel.

The two sets of fastening components 31 are respectively located on the upper and lower sides of the air inlet pipe 17. The fastening component 31 includes:

[0114] A fastening box 32. The fastening box 32 is inside the left side wall 104 of the housing along the up and down direction. A spring fixing block 45 is fixedly arranged inside the left side wall 104 of the housing. A fifth spring is fixedly connected between the spring fixing block 45 and the side of the fastening box 32 away from the air inlet pipe 17. A first mating surface 33 is provided on the outer left wall of the fastening box 32. The first mating surface 33 is an inclined surface; the height of one end of the first mating surface 33 close to the inside of the left side wall 104 of the housing is higher than the height of the end of the first mating surface 33 away from the inside of the left side wall 104 of the housing; a sliding groove 34 is provided on the right side inside the fastening box 32;

[0115] A conical block 36. A protruding portion 37 is provided on the right side of the conical block 36. The protruding portion 37 is slidably connected in the sliding groove 34. A third spring 38 is fixedly connected between the protruding portion 37 and the inner wall of the sliding groove 34;

[0116] The L-shaped block 39 is rotatably connected to the side wall of the fastening box 32 through a shaft in the front-rear direction, and a fourth spring 40 is fixedly connected between the L-shaped block 39 and the inner wall of the lower end of the fastening box 32;

[0117] The fastening block 41 is slidably connected to the inner wall of the fastening box 32 in the up-down direction, and the fastening block 41 is in contact with one end of the L-shaped block 39 close to the air inlet pipe 17;

[0118] The unlocking block 42 is fixedly connected to the outside of the left side wall 104 of the housing through a second spring 43. A through hole 35 in the left-right direction is provided on the left side wall 104 of the housing, and the through hole 35 is used for the right side of the unlocking block 42 to pass through. A second mating surface 44 is provided on the right side of the unlocking block 42; the second mating surface 44 is an inclined surface, and the second mating surface 44 is used for contact and cooperation with the first mating surface 33.

[0119] A conical surface is provided at the lower left part of the upper conical block 36; a conical surface is provided at the upper left part of the lower conical block 36.

[0120] Wherein, an arc-shaped protrusion can be provided on the outside of the air inlet pipe 17 for pressing the conical surface of the conical block 36;

[0121] The working principle and beneficial effects of the above technical solution are as follows: When the air inlet pipe 17 is not inserted into the fastening assembly 31, the two conical blocks 36 are in contact under the action of the third spring 38 to prevent the internal floating dust from escaping from the housing 1 and polluting the working environment. When the air inlet pipe 17 is inserted, the pipe squeezes the conical block 36 open, and the conical block 36 squeezes one end of the L-shaped block 39, so that the other end of the L-shaped block 39 squeezes the fastening block 41 to fix the air inlet pipe 17 and prevent the pipe from detaching from the housing 1 due to the vibration during the production process of the production device, which affects the cleanliness of the working environment. When it is necessary to remove the air inlet pipe 17; press the unlocking block 42, the first mating surface 33 and the second mating surface 44 are in contact, so that the fastening box 32 moves to both sides, and the third spring 38 drives the conical block 36 to move towards the center. The L-shaped block 39 no longer exerts pressure on the fastening block 41. At this time, pull out the pipe, release the unlocking block 42, and the two conical blocks 36 are in contact under the action of the third spring 38 to isolate the internal and external environments of the housing 1, improve the cleanliness of the device production, and protect the physical health of the staff.
