Description

Technical Field

[0001] The invention belongs to the technical field of green treatment of construction waste, and in particular relates to a green treatment system for construction waste. Background Art

[0002] At present, in the process of promoting green building construction, the traditional construction waste crushing, screening and transportation processes are prone to generate a lot of dust, which not only affects the construction site and the surrounding environment, but also may cause harm to the health of workers and residents. Therefore, it is necessary to improve the existing construction waste treatment equipment for systematic dust removal to meet environmental protection requirements and improve the level of green construction.

[0003] For example, a Chinese utility model patent with authorization announcement number CN216779013U and authorization announcement date 2022.06.21 discloses a dust elimination device for garbage disposal for construction, including a shell, the interior of which is rotatably connected to a rotating rod through a bearing; by starting the first motor and the second motor, the first motor will drive the rotating rod to rotate through the cooperation of the bearing when starting, and the rotating rod will drive multiple crushing blades to rotate together when rotating, which can perform multiple crushing of the garbage, improve the garbage crushing effect, and speed up the work efficiency of the staff. At the same time, by starting the fan, the fan will generate a strong suction force after starting. After the suction force is formed, the dust and impurities generated during the garbage crushing will be sucked into the purification box through the action of the connecting pipe, the suction pipe and the suction hood, which can purify the dust and impurities generated during the garbage crushing, ensuring the health of the staff and protecting the surrounding environment, and has high practicality. However, when the device is in use, the fan conveys a large amount of dust-containing air to the interior of the purification box. The purification box filters the dust through the filter plate. The filtered dust will adhere to the mesh holes of the filter plate, causing the filter plate to be blocked. The blockage of the filter plate will affect the filtering effect, and the device needs to be shut down regularly to manually disassemble and clean the filter plate, affecting the continuity and work efficiency of the operation.

Specific implementation mode

[0026] To clearly illustrate the technical features of this solution, the following is an elaboration of this solution through specific implementation modes and in combination with its attached drawings.

[0027] As Figures 1 to 10As shown, a green treatment system for construction waste includes a crusher 10 and a dust removal device connected to its feed end, the dust removal device includes a fixed installation shell 1, a separation and discharge box 2 for treating sewage is installed at the bottom of the fixed installation shell 1, a rotating cleaning mechanism 3 is installed inside the fixed installation shell 1, a dust filtering mechanism 4 and a rotating suction pipe 5 are installed on the rotating cleaning mechanism 3, a moisture filtering mechanism 6 is installed on the dust filtering mechanism 4, and the moisture filtering mechanism 6 is connected to the rotating suction pipe 5, a circulating adsorption mechanism 7 is installed above the dust filtering mechanism 4, the input end of the circulating adsorption mechanism 7 is connected to the rotating suction pipe 5, and the output end of the circulating adsorption mechanism 7 is connected to the dust filtering mechanism 4, and a driving device 8 is installed on the top of the fixed installation shell 1, and the power output end of the driving device 8 is transmission-connected to the circulating adsorption mechanism 7. A suction track 9 is installed on the crusher 10, and the suction track 9 is connected to the fixed installation shell 1.

[0028] When it is necessary to crush the construction waste, the staff pours the construction waste into the feed port of the crusher 10. The crusher 10 generates dust when crushing the construction waste. The staff starts the drive motor 82 and the dust suction pump. The dust suction pump causes the suction track 9 to generate a suction force to quickly absorb the dust into the interior of the fixed installation shell 1. The airflow entering the interior of the fixed installation shell 1 passes through the dust filter mechanism 4 and the moisture filter mechanism 6 in turn. The dust filter mechanism 4 and the moisture filter mechanism 6 perform dust removal and filtration on the air. At the same time, the drive motor 82 drives the circulating adsorption mechanism 7, the moisture filter mechanism 6, the rotating suction pipe 5 and the rotating cleaning mechanism 3 to rotate. When the ring adsorption mechanism 7 rotates, it generates suction force to transport the cleaning liquid inside the separation sewage box 2 to the dust filtering mechanism 4, so that the dust filtering mechanism 4 remains moist. Keeping the dust filtering mechanism 4 moist can enhance the dust removal and filtering effect. When the rotating cleaning mechanism 3 rotates, it cleans the surface of the dust filtering mechanism 4, effectively avoiding dust clogging the dust filtering mechanism 4 and ensuring the air circulation of the dust filtering mechanism 4. The moisture filtering mechanism 6 dehumidifies and filters the air passing through the dust filtering mechanism 4. The cleaning liquid passes through the dust filtering mechanism 4 and drives the dirt to fall into the separation sewage box 2. The separation sewage box 2 is used to separate sewage for recycling.

[0029] like Figures 1 to 3 As shown, the separation sewage tank 2 includes a water storage tank 21 installed at the bottom of the fixed installation shell 1, a partition filter wall 22 is provided at the axial position of the water storage tank 21, a sewage filter layer 23 is installed on the partition filter wall 22, a guide sewage bucket 24 is installed at the bottom of the partition filter wall 22, a sewage pipe 25 is installed at the bottom of the guide sewage bucket 24, and a first suction connecting pipe 26 is also installed on the partition filter wall 22, one end of the first suction connecting pipe 26 is rotatably connected to the rotating suction pipe 5, and the other end extends into the bottom of the inner cavity of the water storage tank 21.

[0030] The water storage tank 21 is used to store the cleaning liquid. The rotary suction pipe 5 sucks the cleaning liquid inside the water storage tank 21 through the first suction connection pipe 26. The partition filtering wall 22 and the guiding sewage hopper 24 are used to receive the sewage of the dust filtering mechanism 4. When the sewage enters the partition filtering wall 22, the partition filtering wall 22 cooperates with the sewage filtering layer 23 to filter the sewage, so that the dust in the sewage precipitates into the guiding sewage hopper 24 to form a sludge layer. When it is necessary to remove the sludge inside the guiding sewage hopper 24, the staff can directly open the sewage pipe 25 to discharge the sludge.

[0031] As Figure 3 , Figure 4 and Figure 5 shown, the rotating cleaning mechanism 3 includes a first fixed base 31 fixedly installed inside the fixed installation shell 1. A rotating installation frame 32 is installed on the first fixed base 31. A plurality of installation slide rails are provided on the rotating installation frame 32. A fixed brush strip 33 and a fixed scraping strip 34 are installed inside the installation slide rails. The fixed brush strip 33 and the fixed scraping strip 34 are arranged at intervals.

[0032] When the rotary suction pipe 5 rotates, it will drive the rotating installation frame 32 to rotate on the first fixed base 31. When the rotating installation frame 32 rotates, it will drive the fixed brush strip 33 and the fixed scraping strip 34 to rotate synchronously. When the fixed brush strip 33 and the fixed scraping strip 34 rotate, they will frictionally clean the surface of the dust filtering mechanism 4. The cooperation of the fixed brush strip 33 and the fixed scraping strip 34 can effectively remove the dirt accumulated on the dust filtering mechanism 4 and ensure the smoothness of the filtration of the dust filtering mechanism 4.

[0033] As Figure 4 and Figure 6As shown in the figure, the dust filtering mechanism 4 includes a second fixed base 41 installed on the first fixed base 31. A limit installation groove is provided on the second fixed base 41, and a filter layer mounting frame 42 is installed in the limit installation groove. The limit installation groove can both limit the filter layer mounting frame 42 and facilitate the disassembly of the filter layer mounting frame 42. A dust filter layer 43 is provided on the filter layer mounting frame 42, and the outer wall of the dust filter layer 43 abuts against the fixed brush strip 33 and the fixed scraping strip 34. The filter layer mounting frame 42 is used to limit and install the dust filter layer 43, so that the outer wall of the dust filter layer 43 always abuts against the fixed brush strip 33 and the fixed scraping strip 34. A diversion installation cover 44 is also installed on the second fixed base 41. Vertically limited clamping strips 442 are symmetrically provided at the top of the diversion installation cover 44, and a limit installation hole 441 is provided at the axial center position of the diversion installation cover 44. The diversion installation cover 44 is pressed on the top of the filter layer mounting frame 42 and the dust filter layer 43, which can effectively ensure the stability of the installation of the filter layer mounting frame 42 and the dust filter layer 43. A flow track is provided inside the diversion installation cover 44, and the flow track is communicated with the circulating adsorption mechanism 7. The dust filter layer 43 can effectively filter the dust in the air. When the circulating adsorption mechanism 7 rotates, it will suck the cleaning liquid and transport the cleaning liquid into the flow track inside the diversion installation cover 44, and the flow track will then transport the cleaning liquid onto the dust filter layer 43 to wash the dust filter layer 43 to ensure the filtering effect of the dust filter layer 43.

[0034] As Figure 4 and Figure 7 shown in the figure, the moisture filtering mechanism 6 includes a limit installation track 61 rotatably installed on the rotary suction pipe 5. A first limit card slot 611 is provided on the outer side of the limit installation track 61, and the first limit card slot 611 is slidably connected with the vertically limited clamping strip 442. An extrusion plate 62 is slidably installed inside the limit installation track 61. A first convex block 621 is provided at the bottom of the extrusion plate 62. A rotary push plate 63 is provided at the bottom of the limit installation track 61, and the rotary push plate 63 is fixedly connected with the rotary suction pipe 5. A second convex block 631 is provided at the top of the rotary push plate 63. A dehumidification filter layer 64 is also installed inside the limit installation track 61. A circulation cover plate 65 is installed at the top of the limit installation track 61. A number of circulation holes are provided on the circulation cover plate 65, the extrusion plate 62 and the rotary push plate 63.

[0035] The circulation holes provided on the circulation cover plate 65, the extrusion plate 62, and the rotating push plate 63 are all used for air circulation. When the cleaning liquid cleans the dust filter layer 43, the humidity of the air passing through the dust filter layer 43 increases. When the relatively humid air passes through the dehumidification filter layer 64, the dehumidification filter layer 64 can filter the moisture in the air. When the rotating suction pipe 5 rotates, it drives the rotating push plate 63 and the second convex block 631 to rotate. The second convex block 631 and the first convex block 621 are spiral structures with matching shapes, which keep the extrusion plate 62 and the rotating push plate 63 in a horizontal state. When the second convex block 631 rotates, it pushes the extrusion plate 62 into the interior of the limit installation track 61 through the first convex block 621, so that the extrusion plate 62 squeezes the dehumidification filter layer 64 to prevent the dehumidification filter from being saturated by adsorption, and keeps the air in a relatively dry state.

[0036] As Figure 3 , Figure 4 and Figure 8 shown, the circulating adsorption mechanism 7 includes a second suction connection pipe 71 installed on the rotating suction pipe 5. The top of the second suction connection pipe 71 is provided with a docking socket 711, and the docking socket 711 is connected to the driving device 8. The bottom of the second suction connection pipe 71 is provided with a communication hole 712, and the communication hole 712 is communicated with the rotating suction pipe 5. A compression spring 714 and a piston 715 are installed inside the second suction connection pipe 71, and the piston 715 extends towards the communication hole 712. A lifting limit groove 713 is provided on the outer wall of the second suction connection pipe 71. A driving guide pipe 72 is rotatably installed outside the second suction connection pipe 71. A plurality of second limit card slots 721 are provided on the outer side of the driving guide pipe 72, and the second limit card slots 721 are slidably connected with the vertical limit card strip 442. The second limit card slots 721 and the vertical limit card strip 442 cooperate to limit the driving guide pipe 72. A circulating driving groove 722 is provided on the inner wall of the driving guide pipe 72, and the circulating driving groove 722 is inclined on the inner wall of the driving guide pipe 72. The upper end of the driving guide pipe 72 is provided with a liquid outlet 723, and the liquid outlet 723 is connected to the flow track inside the diversion installation cover 44. A lifting suction piston 73 is installed between the driving guide pipe 72 and the second suction connection pipe 71.

[0037] The drive motor 82 drives the second suction connecting pipe 71 to rotate. When the second suction connecting pipe 71 rotates, it drives the lifting suction piston 73 to rotate synchronously. When the lifting suction piston 73 rotates, it is guided by the circulating drive groove 722 to rotate. The circulating drive groove 722 causes the lifting suction piston 73 to perform a circulating lifting and lowering movement. When the lifting suction piston 73 rises inside the drive guide pipe 72, it drives the piston 715 to rise, opening the communication hole 712. The rotating suction pipe 5 communicates with the communication hole 712, and the rotating suction pipe 5 sucks the cleaning liquid inside the separation and sewage discharge tank 2 through suction. The cleaning liquid is sucked into the inside of the drive guide pipe 72. When the guide ball 732 moves to the highest point of the circulating drive groove 722, it will intermittently move downward along the circulating drive groove 722 gradually, causing the lifting suction piston 73 and the piston 715 to compress the spring 714 and push the piston 715 to block the communication hole 712. The cleaning liquid enters the upper layer of the lifting suction piston 73 under the pressure of the lifting suction piston 73. The lifting suction piston 73 has a one-way blocking function. When the lifting suction piston 73 rises again in the cycle, it pushes the cleaning liquid in its upper layer into the liquid outlet 723. The liquid outlet 723 transports the cleaning liquid to the diversion mounting cover 44 through a connecting pipe. At the same time, the bottom of the lifting suction piston 73 re-sucks the cleaning liquid into the drive guide pipe 72, effectively circulating and sucking the cleaning liquid.

[0038] As Figure 8 and Figure 9 As shown, a limiting slider 731 is provided on the inner wall of the lifting suction piston 73. The limiting slider 731 is slidably connected to the lifting limiting groove 713. A guide ball 732 is provided on the outer wall of the lifting suction piston 73. The guide ball 732 cooperates with the circulating drive groove 722. A plurality of through holes are provided on the lifting suction piston 73, and a movable blocking film 734 is provided on the through holes.

[0039] When the second suction connecting pipe 71 rotates, it drives the lifting suction piston 73 to rotate synchronously. When the lifting suction piston 73 rotates, the guide ball 732 moves along the circulating drive groove 722. The circulating drive groove 722 is in an inclined circular shape. The circulating drive groove 722 causes the lifting suction piston 73 to perform a circulating lifting and lowering movement. When the lifting suction piston 73 moves up and down inside the drive guide pipe 72, the blocking film fits above the lifting suction piston 73 to seal the through holes, causing a suction force to be generated at the bottom of the inner cavity of the drive guide pipe 72 when the lifting suction piston 73 rises, allowing the cleaning liquid to enter the inside of the drive guide pipe 72. When the lifting suction piston 73 descends, the cleaning liquid inside the drive guide pipe 72 pushes open the blocking film and passes through the through holes on the lifting suction piston 73 into the upper part of the lifting suction piston 73. When the lifting suction piston 73 rises again, the blocking film fits on the lifting suction piston 73. As the lifting suction piston 73 rises, the cleaning liquid is pushed into the liquid outlet 723.

[0040] As Figure 3 andFigure 10 As shown, the driving device 8 includes a sealing cover 81 installed on the top of the fixed installation shell 1 and a dust suction pump communicated with the inner cavity of the sealing cover 81. A driving motor 82 is installed inside the sealing cover 81, and a planetary gear reducer 83 is also installed on the sealing cover 81. The output end of the driving motor 82 is in transmission connection with the planetary gear reducer 83. A docking plug 84 is installed on the planet carrier of the planetary gear reducer 83, and the docking plug 84 is docked with the docking socket 711 of the second suction connecting pipe 71.

[0041] The sealing cover 81 is sealed and installed on the top of the fixed installation shell 1. The suction force of the dust suction pump can effectively guide the gas flow. At the same time, the driving motor 82 drives the planetary gear reducer 83. When the planet carrier of the planetary gear reducer 83 rotates, it drives the docking plug 84 to rotate synchronously. When the docking plug 84 rotates, it drives the second suction connecting pipe 71 to rotate synchronously.

[0042] As Figure 2 and Figure 3 shown, the suction track 9 includes an annular aisle 91 installed outside the feeding port of the crusher 10. A plurality of air inlets are provided on the annular aisle 91, and each air inlet is provided with a plurality of inclined baffle fan blades 92. The air outlet of the annular aisle 91 is connected to the inside of the fixed installation shell 1.

[0043] When the dust suction pump generates suction force, the annular aisle 91 on the suction track 9 is used to cooperate with the collection of the air flow in the area of the feeding port of the crusher 10. The baffle fan blades 92 can block the construction waste and prevent the construction waste from splashing into the inside of the suction track 9, and can effectively collect the dust in the area of the feeding port of the crusher 10.

[0044] The technical features not described in the present invention can be realized by the prior art and will not be elaborated here. The present invention is not limited to the above specific embodiments, and the changes, modifications, additions or substitutions made by those of ordinary skill in the art within the essence of the present invention shall also fall within the protection scope of the present invention.
