DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] Embodiment 1, as Figure 1 and Figure 2As shown, a dust collection device for treating construction waste comprises a shell 1, a control panel 2 is fixedly installed at the middle of the front end of the shell 1, an induced draft fan 4 is fixedly installed on the inner surface of the shell 1, an air inlet pipe 3 fixedly connected to the shell 1 is fixedly connected to the right end of the induced draft fan 4, a multi-stage filter component 5 is arranged on the inner surface of the shell 1, and a vibration component 6 is arranged on the upper end of the multi-stage filter component 5.

[0022] During the implementation of this embodiment, after the shell 1 is moved to the relevant position, the control panel 2 is operated to make the induced draft fan 4 work to inhale the dust generated in the construction waste treatment process through the air inlet pipe 3. The dust will be separated multiple times through the multi-stage filtering component 5, and the dust generated in the multiple separation processes will be collected in stages. In the process of separation and collection, the separated dust will be vibrated by the vibration component 6 to improve the separation efficiency.

[0023] The control panel 2 mentioned above is a mature control technology means and equipment in the prior art. In this solution, the controllable functions thereof are utilized, and its internal structure, principle and connection method are not further elaborated.

[0024] The induced draft fan 4 mentioned above is a mature air suction technical means and equipment in the prior art. In this solution, it is used to inhale dust, and its internal structure, principle and connection method are not further explained.

[0025] Specifically, in order to achieve multi-stage separation of dust generated by construction waste treatment, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In this embodiment, the multi-stage filtering assembly 5 includes a cylinder 51 fixedly connected to the inner surface of the outer shell 1, the inner surface of the cylinder 51 is connected to the left end of the induced draft fan 4 through a pipeline, a primary separation mechanism 52 is arranged on the inner surface of the cylinder 51, an intermediate separation mechanism 53 is arranged on the inner surface of the outer shell 1 on the left side of the cylinder 51, a filtering mechanism 54 is arranged on the inner surface of the outer shell 1 on the left side of the intermediate separation mechanism 53, and a collecting mechanism 55 is arranged on the lower part of the inner surface of the outer shell 1.

[0026] For further information, see Figure 3 and Figure 4In this embodiment, the primary separation mechanism 52 includes a fixing frame 521 fixedly connected to the inner surface of the outer shell 1, a spiral ring 522 is slidably connected to the inner surface of the cylinder 51 and the inner surface of the fixing frame 521, a limiting block 523 is fixedly connected to the lower part of the outer surface of the spiral ring 522, an oblique bucket 524 slidably connected to the outer surface of the spiral ring 522 is fixedly connected to the inner surface of the cylinder 51 below the spiral ring 522, the lower part of the inner surface of the oblique bucket 524 penetrates and extends to the outer surface of the cylinder 51 and is fixedly connected to a discharge pipe 525, and a connecting pipe 526 is fixedly connected to the upper part of the inner surface of the cylinder 51.

[0027] During the implementation process, the dust is introduced into the cylinder 51 through the induced draft fan 4, and under the action of the spiral ring 522, the dust rises in a spiral manner. While the large particles in the dust rise in a spiral manner under the guidance of the spiral ring 522, due to the effect of gravity, the larger particles cannot continue to maintain the rising state and will fall on the inclined bucket 524 under the action of gravity, and finally be discharged from the inner cavity of the cylinder 51 through the connecting pipe 526, avoiding being carried away by the air flow, thereby reducing dust emissions, improving dust collection efficiency, reducing air pollution, and ensuring the accurate recovery and treatment of different particles, thereby achieving the dual goals of environmental protection and resource recycling.

[0028] For further information, see Figure 3 , Figure 5 and Figure 6 In this embodiment, the intermediate separation mechanism 53 includes a cylinder 531 fixedly connected to the inner surface of the outer shell 1, the cylinder 531 is fixedly connected to the connecting pipe 526, the lower part of the inner surface of the outer shell 1 is fixedly connected to a water tank 532, the inner surface of the cylinder 531 is rotatably connected to a hollow rod 533, the lower end of the hollow rod 533 is fixedly connected to a motor 534, the upper part of the inner surface of the water tank 532 is fixedly connected to a water outlet pipe 536, the water outlet pipe 536 is rotatably connected to the hollow rod 533, and the lower end of the water outlet pipe 536 is fixedly connected to a water pump 535.

[0029] For further information, see Figure 3 , Figure 5 and Figure 6 In this embodiment, the outer surface of the hollow rod 533 is fixedly connected with a conical cylinder 537 connected with the inner surface of the hollow rod 533, the lower part of the outer surface of the hollow rod 533 is fixedly connected with a scraper 1 539 tightly attached to the lower part of the inner surface of the second cylinder 531, and the upper part of the inner surface of the second cylinder 531 is fixedly connected with a connecting pipe 2 538.

[0030] For further information, see Figure 3 and Figure 7In this embodiment, the filtering mechanism 54 includes a cylinder three 541 which is fixedly connected to the inner surface of the shell 1 and the connecting pipe two 538. The upper part of the inner surface of the cylinder three 541 penetrates and extends to the left end of the shell 1 and is fixedly connected to an exhaust pipe 542. The inner surface of the cylinder three 541 is fixedly connected to two bevel rings 543. The lower ends of the two bevel rings 543 are fixedly connected to a plurality of springs 544 which are distributed in an annular manner and at equal distances. The lower ends of the plurality of springs 544 on the same side are fixedly connected to a wavy filter screen 545.

[0031] During the implementation process, the dust separated by the primary separation mechanism 52 will enter the lower part of the inner cavity of the second cylinder 531 through the discharge pipe 525. At this time, the water pump 535 is started, so that the water pump 535 draws water from the water tank 532 and enters the inner cavity of the hollow rod 533 through the water outlet pipe 536. Since the hollow rod 533 is connected to the inner cavity of the conical cylinder 537, the water mist will be sprayed through the nozzle on the conical cylinder 537 to combine with the dust. The output end of the starter motor 534 drives the hollow rod 533 to rotate through the coupling, so that the conical cylinder 537 can rotate to spray water. At the same time, since the outer surface of the conical cylinder 537 is conical, the dust moves along the conical cylinder 537. The outer surface of the cylinder 37 moves upward, and the generated sewage will fall to the lower part of the inner surface of the cylinder 2 531 under the action of gravity. The sewage will be discharged through the pipeline through the rotation and scraping of the scraper 1 539. The water mist spraying is combined with the dust to effectively suppress the diffusion and flying of the dust. The water mist is evenly sprayed through the rotating conical cylinder 537, and the dust is fully in contact with the water mist, which promotes the sedimentation of dust particles and reduces the dust concentration in the air. The rotation and surface design of the conical cylinder 537 make the dust move upward along the surface, which is conducive to the further collection and treatment of the dust, thereby improving the environmental protection effect of waste treatment, reducing environmental pollution, and ensuring the air quality in the workplace.

[0032] Secondly, the dust captured by the water mist will enter the inner cavity of the cylinder three 541 through the connecting pipe two 538. As the air rises, the particles in the dust are filtered again under the action of the wavy filter mesh 545. The wavy filter mesh 545 can effectively increase the filtering area, so that the fine particles in the dust are captured during the rising process of the air, further purifying the dust. This process helps to improve the dust collection efficiency and reduce the emission of unfiltered fine particles, thereby significantly reducing air pollution.

[0033] The motor 534 and the water pump 535 mentioned above are both conventional technical designs in the prior art, and this solution will not further explain their internal structures, principles and connection methods.

[0034] For further information, see Figure 3 and Figure 8In this embodiment, the collecting mechanism 55 includes a placing frame 551 fixedly connected to the discharge pipe 525 and the motor 534, the placing frame 551 is fixedly connected to the inner surface of the outer shell 1, the inner surface of the placing frame 551 is symmetrically fixedly connected with partitions 552, the inner cavity of the placing frame 551 is symmetrically and movably installed with a collecting frame 553, the upper ends of the two partitions 552 are movably installed with a circular hole frame 554, and the cylinder two 531 and the cylinder three 541 are connected to the inner surface of the placing frame 551 through a pipeline.

[0035] As can be seen from the above, the large particles of dust separated by the primary separation mechanism 52 will enter the collecting frame 553 located on the right through the discharge pipe 525. At the same time, the sewage generated during the filtering process of the intermediate separation mechanism 53 will enter the circular hole frame 554 through the pipe under the action of gravity. Under the action of the circular hole frame 554, the dust and water are separated and collected. The dust separated by the filtering mechanism 54 will enter the collecting frame 553 located on the left through the pipe, effectively realizing the fine separation and recovery of dust. The large particles of dust enter the collecting frame 553 through the discharge pipe 525, and the sewage generated during the filtering process separates the dust and water through the circular hole frame 554, ensuring the effective separation and recovery of water and dust. The separated dust is sent to different collection frames 553, avoiding secondary pollution of dust and improving the dust recovery efficiency in the waste treatment process.

[0036] Embodiment 2: Based on Embodiment 1, this embodiment adds a vibration component 6 for vibrating during the dust separation process, so as to achieve the purpose of vibrating during the dust separation process.

[0037] Specifically, in order to vibrate the dust separation process, see Figure 3 , Fig. 9 and Fig.10 In this embodiment, the vibration component 6 includes a semicircular sphere 61 fixedly connected to the lower end of the spiral ring 522, a reciprocating mechanism 62 is provided at the upper end of the placement frame 551, and a rotating mechanism 63 is provided in the inner cavity of the cylinder 541.

[0038] For further information, see Figure 3 and Fig. 9 In this embodiment, the reciprocating mechanism 62 includes two fixed blocks 621 fixedly connected to the upper end of the placement frame 551, the inner surfaces of the two fixed blocks 621 are rotatably connected to the reciprocating rod 622, the left end of the reciprocating rod 622 and the outer surface of the hollow rod 533 are fixedly connected to the gear set 623, the ends of the two fixed blocks 621 close to each other are fixedly connected to the limiting rod 624, and the outer surfaces of the reciprocating rod 622 and the limiting rod 624 are slidably connected to the extrusion block 625.

[0039] During the implementation process, when the motor 534 drives the hollow rod 533 to rotate, the reciprocating rod 622 is driven to rotate under the transmission action of the gear set 623. Since the reciprocating rod 622 of the extrusion block 625 is a sliding connection and under the limiting action of the limiting rod 624, the rotation of the reciprocating rod 622 will drive the extrusion block 625 to move back and forth. During the movement, the semicircular ball 61 at the lower end of the spiral ring 522 will be squeezed, so that the spiral ring 522 can move up and down, and then the dust falling on the spiral ring 522 can be vibrated to help loosen and disperse the accumulated dust particles and prevent dust accumulation during the processing process, thereby improving the dust collection efficiency, ensuring that the dust is more evenly distributed during the collection process, enhancing the overall cleaning effect, reducing environmental pollution, and improving the environmental protection and resource recovery benefits of waste treatment.

[0040] The reciprocating rod 622 and the extrusion block 625 mentioned above constitute a mature ball screw mechanism in the prior art.

[0041] The gear set 623 mentioned above is composed of two bevel gears in the prior art.

[0042] For further information, see Figure 3 and Fig.10 In this embodiment, the rotating mechanism 63 includes a rotating rod 631 rotatably connected to the inner surface of the cylinder three 541, the lower part of the outer surface of the rotating rod 631 and the outer surface of the hollow rod 533 are fixedly connected to a pulley set 632, the outer surface of the rotating rod 631 is fixedly connected to a scraper two 633 tightly attached to the lower part of the inner surface of the cylinder three 541, and the outer surface of the rotating rod 631 is linearly and equidistantly fixedly connected to two extrusion ball rods 634.

[0043] During the implementation process, the rotation of the hollow rod 533 will be transmitted through the pulley set 632, driving the rotating rod 631 to rotate, so that the squeezing ball rod 634 on the rotating rod 631 rotates, and then the lower end of the wavy filter screen 545 can be squeezed. When it moves to the convex part of the lower end of the wavy filter screen 545, the spring 544 is in a compressed state. When the squeezing ball rod 634 rotates to the concave part of the lower end of the wavy filter screen 545, the wavy filter screen 545 is reset under the compression reaction of the spring 544, so that the wavy filter screen 545 vibrates, and the dust trapped on the wavy filter screen 545 is cleaned. The dust is cleaned under the action of the scraper 2 633 and collected in the collection frame 553 on the left through the pipeline, which can prevent the filter screen from being blocked, improve the efficiency of dust collection, ensure that the filter screen maintains efficient operation for a long time, reduce dust pollution, and improve the dust cleaning effect and overall cleaning performance during waste treatment.

[0044] The pulley assembly 632 mentioned above is composed of two pulleys and a belt in the prior art.

[0045] Working process: When in use, the dust is sucked into the primary separation mechanism 52 through the induced draft fan 4 for primary separation of large particles, and then the dust is further captured in the form of water mist under the action of the intermediate separation mechanism 53, and the dust is processed by the filtering mechanism 54. At the same time, the dust retained by the primary separation mechanism 52, the intermediate separation mechanism 53 and the filtering mechanism 54 will be collected in a unified partition by the collecting mechanism 55. In the process of dust processing, the retained dust will be vibrated by the reciprocating mechanism 62 and the rotating mechanism 63.
