Description

Technical Field

[0001] The utility model relates to the field of construction waste recycling, in particular to a construction waste recycling device convenient for screening. Background Technique

[0002] Construction waste can be classified according to different classification criteria. Classified by the generation source, construction waste can be divided into engineering soil, decoration waste, demolition waste, engineering slurry, etc. Classified by the composition, it can be divided into soil, concrete blocks, crushed stones, brick and tile fragments, waste mortar, slurry, asphalt blocks, waste plastics, waste metals, waste bamboo and wood, etc. These classifications are helpful for subsequent treatment and recycling work. Recycling and reusing construction waste helps to reduce resource waste and environmental pollution. By recycling and reusing useful materials in construction waste, the demand for primary resources can be reduced, production costs can be lowered, and at the same time, the pollution of waste to the environment can be reduced.

[0029] In this embodiment:

[0030] A convenient screening construction waste recycling device, as Figures 1-4 shown, includes a base 1, a screening box 2 and a cleaning box 19. One side of the top of the base 1 is fixedly provided with the screening box 2, and a gravel inlet 17 is arranged at the top of the screening box 2. Three first storage bins 3 are slidably arranged inside the screening box 2, and a screening net 4 is installed at the bottom of the three first storage bins 3. A second storage bin 5 is slidably arranged inside the screening box 2 and below the three first storage bins 3, and handles 6 are fixed to the outer sides of the three first storage bins 3 and the second storage bin 5. A washing bin 22 is arranged inside the cleaning box 19, and an electric valve 23 is installed on one side of the cleaning box 19 close to the screening box 2;

[0031] Among them, the cleaning box 19 and the washing bin 22 can enable the gravel to be washed first before entering the screening box 2 to remove the soil and impurities on the surface, thereby reducing the blockage during the screening process and the frequency of cleaning equipment. Three first storage bins 3 and the screening net 4 at their bottoms, as well as the second storage bin 5, are arranged inside the screening box 2, improving the screening accuracy and efficiency, and also enabling the recycled gravel to be classified according to different sizes, facilitating subsequent reuse. The handles 6 reduce the labor intensity and time cost of operation for the operator.

[0032] Refer to Figure 1 、 Figure 2 and Figure 4 , a driving motor 7 is arranged on one side of the screening box 2, and a first rotating rod 8 is installed at the output end of the driving motor 7 and rotatably arranged inside the screening box 2. The other end of the first rotating rod 8 is fixedly provided with a driving wheel 9, and a first transmission belt 10 is sleeved outside the driving wheel 9;

[0033] Among them, the first rotating rod 8 rotates driven by the driving motor 7. At the same time, during the rotation process, the driving wheel 9 is driven to rotate synchronously, and the driving wheel 9 drives the first driven wheel 12 to rotate synchronously through the first transmission belt 10.

[0034] Refer to Figure 1 、 Figure 2 and Figure 4 , a second rotating rod 11 is rotatably arranged on the inner side of the middle part of the screening box 2. The end of the second rotating rod 11 far from the driving motor 7 is fixedly provided with a first driven wheel 12, and the outer side of the first driven wheel 12 is sleeved with the first transmission belt 10. The other end of the first driven wheel 12 is fixedly provided with a second driven wheel 13, and a second transmission belt 16 is sleeved outside the second driven wheel 13;

[0035] Among them, the other end of the first driven wheel 12 is fixed with a second driven wheel 13, and the outside of the second driven wheel 13 is sleeved with a second transmission belt 16. This enables the second rotating rod 11 to receive power through the first driven wheel 12 and also transfer the power to other screening components inside the screening box 2 through the second driven wheel 13 and the second transmission belt 16, realizing multi-stage transmission and distribution of power and improving the overall screening efficiency.

[0036] Refer to Figure 1 、 Figure 2 and Figure 4 As shown in, a third rotating rod 14 is rotatably arranged at the inner bottom of the screening box 2, and a third driven wheel 15 is fixed at the end of the third rotating rod 14 far from the drive motor 7 and is sleeved with the second transmission belt 16;

[0037] Among them, this enables the third rotating rod 14 to effectively receive the power from the second transmission belt 16 and convert it into the screening action inside the screening box 2, further improving the screening efficiency.

[0038] Refer to Figure 1 、 Figure 2 and Figure 4 As shown in, cam-shaped structures are arranged in the middle of the first rotating rod 8, the second rotating rod 11 and the third rotating rod 14, and are successively abutted against the screening meshes 4 at the bottoms of the three groups of first storage bins 3 from top to bottom;

[0039] Among them, the design of the cam-shaped structure abutting against the screening mesh 4, and the intermittent vibration function of the cam-shaped structure can effectively disperse the accumulated crushed stones, ensure the smoothness of the screening mesh 4, and further improve the screening efficiency.

[0040] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in, a support column 18 is fixed on one side of the top of the base 1, and a cleaning box 19 is fixed on the top of the support column 18. A water inlet pipe 20 is arranged on the side of the cleaning box 19 far from the electric valve 23. A drain pipe 21 penetrates through the cleaning box 19 at the bottom of the washing bin 22. A conveyor belt 24 is arranged on the back of the base 1, and the output end of the conveyor belt 24 is adapted to the cleaning box 19;

[0041] Among them, the setting of the cleaning box 19 enables the screened construction waste to be further cleaned, thereby removing the soil and impurities attached to the crushed stones and improving the reuse value of the crushed stones. The water inlet pipe 20 is used to transport the external water source into the inside of the washing bin 22, and the drain pipe 21 is used to discharge the sewage inside the washing bin 22. The conveyor belt 24 is used to transport the crushed stones that need to be recycled and classified into the inside of the washing bin 22.

[0042] The implementation principle of the present utility model is as follows: First, the base 1 is stably placed at a designated position. The external control center is electrically connected to the conveyor belt 24, the electric valve 23, and the drive motor 7 respectively. The conveyor belt 24 is controlled by the external control center for conveying, and the crushed stones to be recycled are placed on the conveyor belt inside the conveyor belt 24, so that the crushed stones are conveyed into the washing bin 22 inside the cleaning box 19. Then, water is injected into the inside of the washing bin 22 through the water inlet pipe 20, so that the dust, soil and other attachments attached to the outer surface of the crushed stones inside the washing bin 22 are washed off, and the sewage is discharged outward through the drain pipe 21. Then, the electric valve 23 is opened through the external control center, so that the crushed stones inside the washing bin 22 are discharged into the inside of the crushed stone inlet 17 and fall into the inside of the screening box 2. When the crushed stones fall into the inside of the screening box 2, the drive motor 7 is turned on through the external control center to drive the first rotating rod 8 to rotate. The first rotating rod 8 drives the first driven wheel 12 to rotate through the first transmission belt 10 sleeved on the outside of the driving wheel 9 fixedly connected to its tail. The first driven wheel 12 can drive the second rotating rod 11 and the second driven wheel 13 to rotate simultaneously. The second driven wheel 13 drives the third driven wheel 15 to rotate through the second transmission belt 16 sleeved on the outside. The third driven wheel 15 can drive the third rotating rod 14 to rotate synchronously. Thus, the first rotating rod 8, the second rotating rod 11, and the third rotating rod 14 provide an intermittent vibration function for the screening nets 4 at the bottoms of the three first storage bins 3 inside the screening box 2 through the cam-shaped structures arranged on their outsides. Then, the crushed stones inside the three first storage bins 3 are screened and recycled through the targeting of the three screening nets 4. The crushed stones with the smallest outer diameter will fall into the inside of the second storage bin 5. Finally, by pulling the handles 6 on the outsides of the three first storage bins 3 and the second storage bin 5, they are pulled out of the inside of the screening box 2 and sorted and recycled according to different outer diameter sizes.

[0043] Parts not involved in the present utility model are the same as or can be implemented by using the prior art, and will not be elaborated here too much.

[0044] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model, and they are not limitations on the utility model. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
