Description

Technical Field

[0001] This utility model belongs to the field of construction waste technology, specifically referring to a construction waste recycling and reuse equipment. Background Technology

[0002] Construction waste refers to the slag, waste soil, and discarded materials generated by construction units or individuals during the construction or demolition of various buildings and structures. Construction waste that has not been effectively crushed and screened has a low resource recycling rate, and a large amount of reusable materials are wasted.

[0003] In existing technologies, with the innovation of processing equipment, the crushing of construction waste has gradually shifted from manual crushing to machine crushing. Although general equipment can quickly crush construction waste, some waste remains large in volume after crushing, and the crushing is often not thorough enough, resulting in low subsequent processing efficiency and difficulty in meeting the standard particle size requirements for resource recycling. Furthermore, general crushing equipment does not have the function of screening the crushed construction waste, requiring additional manual screening work. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a construction waste recycling and reuse equipment to solve the problems of incomplete crushing, low screening efficiency and low resource utilization.

[0005] The technical solution adopted in this application is as follows:

The screening bottom plate has a discharge port on the side near the back plate, and the crushing shell is located on the side away from the discharge port.

[0010] Preferably, the blades are distributed in a sinusoidal curve on the outer cylindrical surface of the third rotating shaft, and an extension plate is provided at the free end of the blade. The extension plate has an arc-shaped structure and its bottom is set close to the screening bottom plate.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] Example 1

[0032] Please refer to Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a construction waste recycling and reuse equipment, including a workbench 1. The workbench 1 is provided with a screening cylinder 2 with a top opening. The top opening of the screening cylinder 2 is provided with a crushing frame 3. The crushing frame 3 is provided with a crushing device 4. The crushing device 4 includes a crushing shell 41, a first rotating shaft 42 and a second rotating shaft 43. The crushing shell 41 is fixedly mounted on the crushing frame 3. The first rotating shaft 42 and the second rotating shaft 43 are arranged in parallel and rotate between the inner walls of the crushing shell 41. The outside of the first rotating shaft 42 and the second rotating shaft 43 are both coaxially fixedly connected with crushing rollers 44. The first rotating shaft 42 is coaxially connected with a first gear 64 about the outside of the crushing shell 41. The outside of the second rotating shaft 43 is coaxially connected with a second gear 65. The first gear 64 and the second gear 65 mesh with each other. A drive device 6 is provided on one side of the workbench 1 and is connected to the first rotating shaft 42 and the second rotating shaft 43 for transmission.

[0033] The crushing shell 41 is provided with a feed hopper 45 at the top, the crushing frame 3 is a square frame plate structure and its outer periphery is fixedly connected to one end of the top of the screening cylinder 2, and a first discharge port 46 is provided between the crushing shell 41 and the crushing frame 3.

[0034] When using this structure, the first rotating shaft 42 is driven to rotate by the drive device 6. The meshing of the first gear 64 and the second gear 65 then drives the second rotating shaft 43, which is coaxial with the second gear 65, to rotate. As a result, the crushing rollers 44 located outside the first rotating shaft 42 and the second rotating shaft 43 move inward relative to each other. The construction waste to be processed is fed from the feed hopper 45. The two sets of parallel crushing rollers 44 can crush the construction waste more evenly and thoroughly, providing smaller particle size raw materials for subsequent processing. After preliminary crushing, the waste enters the screening cylinder 2 below through the first discharge port 46.

[0035] Example 2

[0036] refer to Figure 2 As shown, in order to solve the problems of insufficient crushing of construction waste and low screening efficiency of crushed waste, the screening cylinder 2 is provided with a crushing and screening component 5. The crushing and screening component 5 includes a third rotating shaft 51 rotatably disposed on the inner wall of the screening cylinder 2. The driving device 6 is connected to the third rotating shaft 51 in a transmission connection. Several sets of blades 52 are arranged on the outer periphery of the third rotating shaft 51.

[0037] The screening cylinder 2 is composed of a front plate 21, a back plate 22, two sets of side plates 23, and a screening bottom plate 24. The front plate 21, back plate 22, and side plates 23 form a cavity that runs vertically through the interior. One end of the screening bottom plate 24 is fixed to the front plate 21, and both sides are fixed to the side plates 23. The screening bottom plate 24 is arranged in a downwardly arched semi-circular shape, and the bottom of the screening bottom plate 24 has evenly spaced discharge holes 25. The side of the screening bottom plate 24 closest to the back plate 22 has a discharge port 26, and the crushing shell 41 is located on the side away from the discharge port 26. The bottom of the screening cylinder 2 is provided with two sets of guide plates, which are located on both sides of the bottom of the discharge holes 25 to guide the material and prevent splashing.

[0038] Combination Figure 4 and Figure 5 As shown, the blades 52 are distributed in a sinusoidal curve on the outer cylindrical surface of the third rotating shaft 51. An extension piece 53 is provided at the free end of the blades 52. The extension piece 53 has an arc-shaped structure and its bottom is close to the screening bottom plate 24.

[0039] When using this structure, the rotation of the third rotating shaft 51 drives the blade 52 to rotate inside the screening cylinder 2. While the extended plate 53 on the outside of the blade 52 is crushing the waste for the second time, the arc-shaped structure on the outer periphery can squeeze the waste when it is in contact with the bottom plate, so that the waste of the correct size is discharged from the discharge hole 25. During the rotation process, the waste is evenly distributed from the first discharge port 46 to the discharge port 26.

[0040] In addition, larger waste particles are discharged through 26 discharge ports and can then be crushed again. Through multiple crushing processes, the practicality of the crushing and recycling equipment is ensured.

[0041] Example 3

[0042] refer to Figure 1 As shown, a drive frame 61 is fixedly provided on the outer side of the front plate 21, and the drive device 6 is provided on the drive frame 61. The drive device 6 includes a motor 62 and a drive shaft 63. The motor 62 is provided on the drive frame 61, and the drive shaft 63 is rotatably provided on the outer side of the screening cylinder 2 through a bearing and is coaxially connected to the third rotating shaft 51. The drive shaft 63 is connected between the output shaft of the motor 62 and the third rotating shaft 51. A coaxial driving pulley 66 is also provided on the outer periphery of the drive shaft 63, and a driven pulley 67 is also coaxially provided on the outer periphery of the first rotating shaft 42. A belt 68 is provided between the driving pulley 66 and the driven pulley 67.

[0043] In the preferred embodiment, a reducer 69 is also provided between the output shaft of the motor 62 and the drive shaft 63. The output shaft of the motor 62 is connected to the input end of the reducer 69, and the output end of the reducer 69 is connected to the drive shaft 63.

[0044] When using this structure, the output shaft of motor 62 drives drive shaft 63 to rotate via reducer 69. Drive shaft 63 drives third shaft 51 to rotate on the same axis, thereby causing blade 52 to perform secondary crushing. Third shaft 51 drives drive pulley 66 to rotate, which in turn drives driven pulley 67 to rotate via belt 68. Then, first shaft 42 rotates with driven pulley 67. Under the meshing action of first gear 64 and second gear 65, second shaft 43 rotates, thereby crushing roller 44 to perform crushing. By setting up a set of motors 62 to synchronously drive crushing device 4 and crushing and screening assembly 5, it is environmentally friendly and energy-saving, reducing maintenance costs.

[0045] It should be noted that although embodiments of the present invention have been shown and described, those skilled in the art who design similar structures and embodiments without departing from the spirit of the present invention should all fall within the protection scope of the present invention.
