The market demand continues to rise and the production scale is also expanding.

[0003] However, in the production and processing of asbestos-free calcium silicate boards, a large amount of construction waste will be generated due to cutting, grinding, scraps and inevitable losses in the production process. If these wastes are not effectively recycled, on the one hand, they will take up a lot of stacking space, leading to increased operating costs for the company; on the other hand, random discarding or landfilling will cause pollution to the natural environment such as soil and water, which violates the development concept of green environmental protection.

[0013] In a preferred embodiment: A second conveyor belt is provided below both the first guide plate and the second guide plate. A limiting plate is movably provided on the side of the second conveyor belt. A third conveyor belt is provided between the two third guide plates at the bottom end of the recycling bin.

[0014] In a preferred embodiment: Two cabinet doors are hinged to one end of the recycling bin, and transparent windows are provided on both cabinet doors. The transparent windows are made of acrylic plates.

[0015] The recycling method of the construction waste recycling device includes the following contents: S1: Place the asbestos-free calcium silicate board waste on the first conveyor belt. The first conveyor belt conveys the waste to above the crushing box, and the waste falls into the crushing box. Start the crushing motor. The crushing motor drives one of the crushing knives to rotate. Through the meshing action of the two first gears, the other crushing knife also rotates accordingly. The two crushing knives crush the waste, and the crushed waste falls into the recycling bin through the conical structure at the lower end of the crushing box; S2: Start the rotating motor. The output shaft of the rotating motor drives the turntable to rotate. The eccentric column on the turntable drives the first rotating shaft to move left and right through the connecting rod, and then drives the first vibrating screen and the second vibrating screen to vibrate synchronously. Because the first vibrating screen and the vibrating screen are connected by the first elastic sheet and the second elastic sheet, relative vibration will occur when the turntable driven by the rotating motor rotates. The crushed waste is screened on the first vibrating screen and the second vibrating screen. Large particle materials remain on the first vibrating screen, medium particle materials remain on the second vibrating screen, and small particle materials fall onto conveyor belt three and are conveyed away; S3: After the screening is completed, start the adjustment motor in the recovery mechanism. One output shaft of the adjustment motor drives the second rotating shaft to rotate through the sprocket and chain. At the same time, the second gear on the second rotating shaft drives the third gear to rotate, and the third gear drives the rack to move, so that the baffle slides upward to open. The first vibrating screen and the second vibrating screen rotate driven by the other output shaft of the adjustment motor. At the same time, start the cylinder. The first guide plate and the second guide plate slide upward driven by the cylinder. When the first vibrating screen and the second vibrating screen rotate a certain angle, the lower ends of the first vibrating screen and the second vibrating screen are respectively in contact with the first guide plate and the second guide plate, and then the particles remaining on the first vibrating screen and the second vibrating screen after screening are exported through the first guide plate and the second guide plate, and the particles are guided onto conveyor belt two, and cooperate with the third guide plate at the bottom of the recovery box to guide the remaining particles onto conveyor belt three to complete the recovery of the screened particles.

[0016] In the vibration screening process of the present invention, the rotation motor is started. The output shaft of the rotation motor powerfully drives the turntable to rotate at a high speed. The eccentric column fixedly installed on one side of the turntable then makes a circular motion. The eccentric column cleverly drives the first rotating shaft to displace through the connecting rod, thereby causing the first vibrating screen and the second vibrating screen installed at different heights and with U-shaped fixed frames on their outer side walls to generate strong and stable vibrations. During the vibration process, the elastic member I between the two U-shaped fixed frames and the elastic member II between the upper U-shaped fixed frame and the inner wall of the recycling box play a key role. The elastic member I is composed of a plurality of first fixing plates provided on the side walls of the two U-shaped fixed frames and first elastic sheets installed between the upper and lower adjacent fixing plates. The elastic member II is composed of a second fixing plate installed on the inner wall of the recycling box and a second elastic sheet between the adjacent first fixing plate and the second fixing plate. These elastic members can make the first vibrating screen and the second vibrating screen have regular left and right shaking and vibrations. Under this stable and efficient vibration effect, the crushed waste materials are accurately screened on the first vibrating screen and the second vibrating screen. Particles of different diameters can accurately stay on the first vibrating screen and the second vibrating screen respectively according to the set sieve hole size, and particles of different particle sizes can be separated to meet different recycling requirements, effectively avoiding the mixing of particles, and making it more convenient to use the screened particles as raw materials and mix them with new raw materials in a certain proportion to re-produce calcium silicate boards or other building materials. For example, fine particles can be used to produce the surface layer material of calcium silicate boards, and coarse particles can be used to produce the core layer material, thereby realizing the recycling of waste materials.

[0017] In the actual operation of the present invention, when crushing waste materials, the asbestos-free calcium silicate board waste materials are placed on the first conveyor belt. The first conveyor belt steadily conveys the waste materials above the crushing box, and the waste materials can accurately fall into the crushing box. At this time, the crushing motor is started. The power output of the crushing motor directly drives one of the crushing knives to rotate at a high speed. Since the outer walls of the two crushing knives are respectively fixedly connected with meshing first gears, this gear transmission design enables the other crushing knife to rotate synchronously. The two oppositely rotating crushing knives are like efficient crushers, performing all-round crushing on the waste materials falling into them. The crushed waste materials quickly and smoothly fall into the recycling box through the unique frustum-shaped structure at the lower end of the crushing box. This crushing method lays a solid foundation for the subsequent screening and recycling work, greatly improving the efficiency of the overall recycling process. Description of the Drawings

The elastic member two includes a plurality of second fixing plates 13 installed on the inner wall of the recycling bin 1. Between the adjacent first fixing plates 11 and the second fixing plates 13, there is installed a second elastic sheet 14.

[0023] The crushing mechanism includes a crushing box 15 installed at the upper end of the recycling bin 1 and two symmetrically distributed crushing knives 16 rotatably connected to the inner wall of the crushing box 15. On the outer walls of the two crushing knives 16, there are fixedly connected first gears 17, and the two first gears 17 mesh with each other. The shaft end of one of the crushing knives 16 is fixedly connected to the output shaft of a crushing motor 18, and the crushing motor 18 is installed on the outer wall of the crushing box 15. The lower end of the crushing box 15 is of a frustum structure. Above the crushing box 15, there is a conveyor belt one 19 for transporting waste materials.

The first vibrating screen 2 and the second vibrating screen 3 rotate driven by the other output shaft of the adjusting motor 24. At the same time, start the air cylinder 33, and the first guide plate 21 and the second guide plate 22 slide upward driven by the air cylinder 33. When the first vibrating screen 2 and the second vibrating screen 3 rotate a certain angle, the lower ends of the first vibrating screen 2 and the second vibrating screen 3 are respectively in contact with the first guide plate 21 and the second guide plate 22, and then the particles remaining on the first vibrating screen 2 and the second vibrating screen 3 after screening are led out through the first guide plate 21 and the second guide plate 22, and the particles are guided onto the second conveyor belt 35. The limiting plate 36 on the side of the second conveyor belt 35 prevents the particles from falling, and cooperates with the third guide plate 23 at the bottom of the recovery box 1 to guide the remaining particles onto the third conveyor belt 37, completing the recovery of the screened particles.

10. A recycling method for a construction waste recycling device according to any one of claims 1-9, characterized in that: Includes the following: S1: Place the non-asbestos calcium silicate board waste on conveyor belt 1 (19). Conveyor belt 1 (19) transports the waste above the crushing box (15), and the waste falls into the crushing box (15). Start the crushing motor (18). The crushing motor (18) drives one of the crushing knives (16) to rotate. Through the meshing of the two first gears (17), the other crushing knife (16) also rotates accordingly. The two crushing knives (16) crush the waste, and the crushed waste falls into the recycling box (1) through the frustum-shaped structure at the lower end of the crushing box (15). S2: Start the rotating motor (5). The output shaft of the rotating motor (5) drives the turntable (8) to rotate. The eccentric post (9) on the turntable (8) drives the first rotating shaft (6) to move left and right through the connecting rod (7), and then drives the first vibrating screen (2) and the second vibrating screen (3) to vibrate synchronously. Because the first vibrating screen (2) and the vibrating screen (3) are connected by the first elastic sheet (12) and the second elastic sheet (14), relative vibration will occur when the turntable (8) driven by the rotating motor (5) rotates. The crushed waste is screened on the first vibrating screen (2) and the second vibrating screen (3). Large-particle materials remain on the first vibrating screen (2), medium-particle materials remain on the second vibrating screen (3), and small-particle materials fall onto conveyor belt 3 (37) and are transported away. S3: After the screening is completed, start the adjustment motor (24) in the recycling mechanism. One output shaft of the adjustment motor (24) drives the second rotating shaft (25) to rotate through the sprocket and chain (29). At the same time, the second gear (26) on the second rotating shaft (25) drives the third gear (27) to rotate, and the third gear (27) drives the rack (28) to move, so that the baffle (20) slides upward to open. The first vibrating screen (2) and the second vibrating screen (3) rotate driven by the other output shaft of the adjustment motor (24). At the same time, start the cylinder (33). The first guide plate (21) and the second guide plate (22) slide upward driven by the cylinder (33). When the first vibrating screen (2) and the second vibrating screen (3) rotate a certain angle, the lower ends of the first vibrating screen (2) and the second vibrating screen (3) respectively contact the first guide plate (21) and the second guide plate (22), and then the particles remaining on the first vibrating screen (2) and the second vibrating screen (3) after screening are exported through the first guide plate (21) and the second guide plate (22), and the particles are guided onto conveyor belt 2 (35). Together with the third guide plate (23) at the bottom of the recycling box (1), the remaining particles are guided onto conveyor belt 3 (37) to complete the recycling of the screened particles.
