[0002] During the construction or renovation of a building, various construction wastes of different particle sizes are easily generated at the construction site, such as slag, crushed stone, abandoned materials, silt and other wastes. In the process of waste treatment, in order to screen out wastes of different particle sizes for subsequent classification and recycling, the mixed wastes are usually poured directly into the vibrating screen, so that the vibrating screen drives the wastes to vibrate toward the discharge port, and the wastes fall onto the screen layer that can just intercept their own particle size, thereby realizing the classification and recycling of the wastes.

[0003] However, in actual use, it was found that the vibrating screen is generally in a high-frequency vibration state when working. Although this state can improve the overall screening efficiency, the dust on the surface of the waste will also fly to the outside of the vibrating screen, thereby polluting the external environment and even causing serious impact on the respiratory tract of the workers.

[0033] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0034] The key concept of the utility model is that the water mist sprayed by the spraying component mixes with the dust, falls back into the inside of the vibrating screen, and flows to the sewage outlet, thereby solving the dust problem; and the scraping component regularly scrapes the bottom of the vibrating screen, thereby preventing the dust and sand from remaining in the vibrating screen for a long time, thereby affecting the normal waste screening work.

[0035] Please refer to Figure 1 to Figure 2 The construction waste separation device provided by the utility model comprises a vibrating screen body 1, a spraying assembly 2 and a scraping assembly 3;

[0036] The spray end of the spray assembly 2 is arranged toward the vibrating surface of the vibrating screen body 1;

[0037] A sewage outlet 11 is provided at the bottom of the vibrating screen body 1;

[0038] The scraper assembly 3 is disposed inside the vibrating screen body 1 , and the scraper end of the scraper assembly 3 is disposed toward the sewage outlet 11 .

[0039] Specifically, the sewage outlet 11 is arranged at the lowest point of the vibrating screen body 1, and the positional relationship between the scraper assembly 3 and the vibrating screen body 1 can be changed according to the position of the sewage outlet 11, that is, along the moving direction of the material, when the sewage outlet 11 is arranged at one end of the bottom of the vibrating screen body 1, the scraper assembly 3 is arranged at the other end of the bottom of the vibrating screen body 1, and the scraping end of the scraper assembly 3 is arranged toward the sewage outlet 11; when the sewage outlet 11 is arranged in the middle of the bottom of the vibrating screen body 1, two scraper assemblies 3 whose driving directions are parallel to the moving direction of the material are arranged, and the scraping ends of the two scraper assemblies 3 are opposite and are both arranged toward the sewage outlet 11.

[0040] From the above description, it can be seen that the beneficial effects of the utility model are: providing a construction waste separation device, which can spray water mist through the spray component 2, so that the dust and water mist can be mixed and fall back into the inside of the vibrating screen and flow to the sewage outlet 11; compared with the existing construction waste separation device, it can not only effectively solve the dust problem, but also the scraper component 3 arranged on the vibrating screen body 1 can also regularly scrape the bottom of the vibrating screen, so as to avoid dust and sand from remaining in the vibrating screen for a long time, thereby affecting the normal waste screening work.

[0041] Further, the spray assembly 2 includes a spray head 21;

[0042] The spray heads 21 are arranged at preset intervals along the moving direction of the material;

[0043] The spray end of the spray head 21 is arranged toward the vibrating surface of the vibrating screen body 1 .

[0044] Specifically, the spray head 21 can be connected to a peripheral water pump device, so that the spray assembly 2 can continuously and stably spray a large amount of water mist.

[0045] From the above description, it can be seen that the design has made specific improvements to the composition structure of the spray assembly 2. The spray heads 21 are set at preset intervals so that the staff can freely adjust the coverage area of ​​the water mist sprayed by the spray heads 21 according to actual spraying needs, thereby ensuring the best spraying effect.

[0046] Furthermore, the scraper assembly 3 includes a scraper 31 and two linear drive devices 32;

[0047] The linear drive device 32 is arranged on the outside of the vibrating screen body 1;

[0048] The driving direction of the linear drive device 32 is parallel to the moving direction of the material;

[0049] Both ends of the scraper 31 are connected to the movable ends of the corresponding linear drive device 32 respectively;

[0050] The scraper 31 is in close contact with the inner bottom surface of the vibration screen body 1 .

[0051] Specifically, the linear drive device 32 is any commercially available device that can drive an object to move linearly, such as a screw rod, a linear guide rail, etc.

[0052] Furthermore, the middle part of the scraper 31 can also be connected to the movable end of the linear drive device 32, and the linear drive device 32 can be set on the side of the highest position of the vibrating screen body 1, so as to push the mud and sand at the highest point to the lowest sewage outlet 11, thereby preventing the mud and sand from remaining inside the vibrating screen body 1.

[0053] Preferably, in order to enable the scraper 31 to move smoothly inside the vibrating screen body 1, an avoidance hole consistent with the moving path of the scraper 31 is provided on the shell of the vibrating screen body 1, so that the two ends of the scraper 31 can respectively pass through the corresponding avoidance grooves and be connected to the movable ends of the corresponding linear drive devices 32; at the same time, a corresponding sealing member can also be provided in the avoidance hole, and the part of the avoidance hole that the scraper 31 does not reach is closed by the sealing member to prevent the water mist sprayed by the spray assembly 2 from leaking out of the avoidance hole.

[0054] From the above description, it can be seen that the design has made specific improvements to the composition structure of the scraper assembly 3. The linear drive device 32 drives the scraper 31 to move back and forth inside the vibrating screen body 1 along the vibration direction of the material, which can effectively push the dust and sediment remaining inside the vibrating screen to the sewage outlet 11, thereby achieving the purpose of cleaning and preventing blockage.

[0055] Furthermore, at least three layers of vibrating screen meshes 12 are provided inside the vibrating screen body 1;

[0056] The mesh diameter of the vibrating screen 12 gradually decreases from top to bottom.

[0057] Specifically, the number of the vibrating screens 12 can be freely increased or decreased according to the types of materials to be screened, so as to ensure that the vibrating screens 12 can filter out all the required materials.

[0058] From the above description, it can be seen that the design has made further improvements to the composition structure of the vibrating screen body 1. According to actual screening needs, a corresponding number of vibrating screens 12 are arranged inside the vibrating screen body 1, and the mesh diameter of the vibrating screen 12 gradually decreases from top to bottom, so that the mixed material can be screened one by one according to different particle sizes to achieve material classification.

[0059] Furthermore, a collection box 4 is provided at the discharge end of each vibrating screen 12;

[0060] A drying device is provided inside the collecting box 4 .

[0061] Due to the high vibration frequency, the slurry formed by water mist and dust will not remain on the screened material on the upper part of the vibrating screen 12, but will be deposited on the bottom of the vibrating screen body 1 through the mesh of the vibrating screen 12, thereby not only avoiding dust but also ensuring the cleanliness of the waste after screening, thereby making the screening effect better.

[0062] From the above description, it can be seen that the water mist sprayed by the spray component 2 can not only mix the dust to form mud, but also wet the material to be filtered. When the material is collected into the aggregate box 4, the drying device inside the aggregate box 4 dries and heats the material, and then it can be restored to its initial dry state.

[0063] Furthermore, the above-mentioned construction waste separation device further includes a sediment collection box 5;

[0064] The sediment collection box 5 is arranged directly below the sewage outlet 11 .

[0065] From the above description, it can be seen that the sludge collection box 5 can receive the mixture of water and dust discharged from the sewage outlet 11, thereby preventing the sludge from falling directly into the workplace and affecting the working environment; at the same time, if the sludge cannot be cleaned up in time, after the water evaporates, the dust will fly again, thereby worsening the working environment.

[0066] Furthermore, the above-mentioned construction waste separation device also includes a filtering device and a water collection tank;

[0067] The sediment collection box 5, the filtering device, the water collection tank and the spray assembly 2 are connected in sequence.

[0068] It can be seen from the above description that this design can realize the recycling of wastewater, thereby saving corresponding usage costs.
