[0002] After construction waste is recycled, recycled aggregates can be obtained and reused. The popularization of recycled aggregates meets the requirements of energy conservation and environmental protection. During the production and preparation process of recycled aggregates from construction waste, a sorting device is often required to achieve screening.

[0003] The sorting device for recycled aggregates from construction waste often sorts through vibration. Considering that the construction waste materials after crushing are generally heavy, it is difficult to process a large amount of materials at one time, and too many materials are likely to reduce the vibration effect and sorting effect. Although the Chinese utility model patent with the application number 202322368755.4 provides a hot aggregate screening device, in which the aperture of the sieve holes from top to bottom of the multi-layer sieve mesh is distributed from large to small, and the distribution of sieve meshes with different apertures is used to enable the sieve meshes in the middle and upper layers to be used for sorting large-particle and easily screened materials in asphalt recycled aggregates.

[0004] However, when there are a large number of materials, the materials cannot be fully screened during the moving process, resulting in the sorting effect still not meeting the actual use requirements. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sorting device for recycled aggregates from construction waste to solve the technical problem of low sorting efficiency of recycled aggregates from construction waste at present.

[0009] Further limited, the first receiving drawer is provided with sieve holes. A first sorting frame is sleeved outside the first receiving drawer. A vibration motor is arranged on the first sorting frame. The first sorting frame is elastically connected to the load-bearing frame through an elastic buffer assembly.

[0010] Further limited, connecting slide bars are arranged on opposite sides of the first receiving drawer. Connecting chutes for sliding connection with the connecting slide bars are arranged on the first sorting frame.

The second receiving drawer is connected to the bearing frame through the second sorting frame. The second receiving drawer is slidably connected to the second sorting frame, and the elastic buffer assembly is located above the second sorting frame.

[0013] Further defined, the feeding port is rotationally connected to the blocking baffle through a motor, and the blocking baffle is located inside the screening drum.

Specific implementation manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-5 , a construction waste recycled aggregate sorting device provided by the present invention includes a load-bearing frame 1, a screening drive 2, a screening drum 3 and a first receiving drawer 19. A first support frame 7 is welded to the top of the load-bearing frame 1. The first support frame 7 is located on the left and right sides of the screening drum 3. The first support frame 7 is rotationally connected to the screening drum 3 through the screening drive 2. The screening drum 3 is horizontally arranged, so that the screening drive 2 can drive the screening drum 3 to rotate around its axis to realize screening.

[0026] A feeding port 5 is welded at the middle position of the screening drum 3 for feeding the construction waste recycled aggregate into the screening drum 3 through the feeding port 5. For example, the feeding port 5 is sequentially connected to the feeding pipe fitting 4, the inclined screw feeder 9 and the quantitative feeding tank 10. The construction waste recycled aggregate in the quantitative feeding tank 10 can be fed into the screening drum 3 through the inclined screw feeder 9 as needed. Scale lines are provided on the inner side wall of the quantitative feeding tank 10, so that it can realize quantitative feeding to meet the use requirements; a second support frame 8 is provided on the inclined screw feeder 9 to support the inclined screw feeder 9, making its use stable and reliable.

[0027] In order to prevent the materials in the screening drum 3 from falling from the feeding port 5, a blocking baffle 14 is selected to be arranged in the feeding port 5. The blocking baffle 14 is connected to the feeding port 5 through a motor 13, so that the motor 13 drives the blocking baffle 14 to open during use, and the motor 13 drives the blocking baffle 14 to block the feeding port 5 during screening.

[0028] The screening drum 3 is provided with screening holes for isolating oversized materials, and the remaining materials fall into the first material collection drawer 19 below the screening drum 3 after being screened by the flipping of the screening drum 3.

[0029] Further explanation, the inside of the first support frame 7 is installed with a machine shell 6, the screening drive 2 is connected to the machine shell 6, the machine shell 6 is provided with a first gear 11 and a second gear 12 meshing with the first gear 11, the output end of the screening drive 2 is connected to the first gear 11, the screening drum 3 is connected to the second gear 12, and the first gear 11 and the second gear 12 form a reduction gear set.

[0030] In order to meet the multi-stage separation of recycled aggregates of construction waste, a first sorting frame 20 is sleeved outside the first material collection drawer 19. The first material collection drawer 19 is connected to the bearing frame 1 through the first sorting frame 20. At the same time, sorting holes are opened on the first material collection drawer 19, and the sorting holes are smaller than the screening holes for further sorting the materials in the first material collection drawer 19.

[0031] At this time, a vibration motor 17 is arranged on the first sorting frame 20. The vibration motor 17 is used to drive the first sorting frame 20 to vibrate up and down. The first sorting frame 20 is elastically connected to the bearing frame 1 through an elastic buffer assembly 21 to realize the sorting of the materials in the first material collection drawer 19.

[0032] The elastic buffer assembly 21 is arranged at the bottom of the first sorting frame 20. The number of the elastic buffer assemblies 21 can be selected as four, and the four elastic buffer assemblies 21 are arranged in an array.

[0033] Preferably, the first material collection drawer 19 is slidably connected to the first sorting frame 20. At this time, connecting slide bars 15 are arranged on the opposite sides of the first material collection drawer 19, and connecting chutes 16 matching the connecting slide bars 15 are opened on the first sorting frame 20 to facilitate the collection of the materials in the first material collection drawer 19.

[0034] In order to prevent the first material collection drawer 19 from disengaging from the first sorting frame 20 when the vibration motor 17 is working, it is selected to be provided with screws between the connecting slide bars 15 and the connecting chutes 16 for locking and limiting.

[0035] Preferably, a second material collection drawer 22 is arranged below the first material collection drawer 19. The second material collection drawer 22 is connected to the bearing frame 1 so that the materials screened by the first material collection drawer 19 fall into the second material collection drawer 22 for collection.

[0036] The second material collection drawer 22 is connected to the bearing frame 1 through a second sorting frame 18. The second material collection drawer 22 is preferably slidably connected to the second sorting frame 18.

[0037] The inner sidewalls of the first material receiving drawer 19, the screening drum 3, and the second material receiving drawer 22 are all provided with nano-ceramic anti-sticking coatings, which improves the anti-sticking and wear-resistant effects of the inner walls of the first material receiving drawer 19, the screening drum 3, and the second material receiving drawer 22.

[0038] During use, on the one hand, start the screening drive 2. With the transmission of the first gear 11 and the second gear 12, the screening drum 3 can be driven to perform a flipping motion at a frequency of 180 degrees each time. Thus, through the rolling flip, efficient screening of the material can be achieved. This method is beneficial for processing a larger amount of material at one time compared to common vibrating screening structures, and solves the problems of excessive stacking of materials and difficult vibrating screening. On the other hand, the falling material will enter the first material receiving drawer 19 inside the first sorting frame 20. At this time, start the vibration motor 17. With the cooperation of the elastic buffer assembly 21, the material that has completed the primary sorting can be further refined and screened, realizing the function of multi-stage screening.

[0039] When the embodiment of the present application is in use:

[0040] The recycled aggregate of construction waste after crushing treatment is stored in the quantitative feeding trough 10. The inner sidewall of the quantitative feeding trough 10 is provided with scale lines, and the user can perform quantitative feeding according to the scale lines.

[0041] During actual operation, the user first uses the inclined screw feeder 9 to send the material in the quantitative feeding trough 10 into the inside of the screening drum 3 through the inclined screw feeder 9, the feeding pipe fitting 4, and the feeding port 5. And start the motor 13, which can drive the blocking baffle 14 to flip and open at the feeding port 5 to achieve feeding.

[0042] After the feeding is completed, remove the feeding pipe fitting 4 from the feeding port 5, and then start the motor 13 to drive the blocking baffle 14 to block the feeding port 5.

[0043] Then, start the screening drive 2. With the transmission of the first gear 11 and the second gear 12, the screening drum 3 can be driven to perform a flipping motion at a frequency of 180 degrees each time. Thus, through the rolling flip, efficient screening of the material can be achieved.

[0044] The falling material will enter the first material receiving drawer 19 inside the first sorting frame 20. At this time, start the vibration motor 17. With the cooperation of the elastic buffer assembly 21, the material that has completed the primary sorting can be further refined and screened, realizing the function of multi-stage screening.
