Description

Technical Field

[0001] This invention relates to the field of environmental protection treatment equipment technology, specifically to an energy-saving and environmentally friendly treatment device for construction waste. Background Technology

[0002] Currently, construction waste is processed through centralized crushing, which generates a large amount of dust and fumes that are directly emitted into the air, causing air pollution. Most existing construction waste is crushed and then collected and treated by spraying towers to atomize and suppress dust. The atomized water vapor mixes with the dust to form a slurry, which traps the dust and achieves the purpose of dust suppression. The gas after dust suppression is then discharged after demisting treatment. The overall structure is simple and can effectively complete the dust treatment work.

[0003] However, in actual use, when dust and smoke are introduced into the existing spray tower, the atomized water vapor and dust are not mixed sufficiently due to the fixed position of the spray structure. As a result, some dust is not intercepted and moves to the outlet position with the airflow, which directly reduces the overall dust treatment effect. Moreover, the sludge formed after mixing adheres to the inner wall of the tower and the filter structure. With long-term use, the filter holes are easily blocked by sludge, which is inconvenient to clean and thus affects the continuous operation of subsequent exhaust gas filtration. Summary of the Invention

[0004] The purpose of this invention is to provide an energy-saving and environmentally friendly treatment device for construction waste, which realizes multi-layer zoned atomization treatment of construction dust in the spray tower, improves the mixing degree of atomized water vapor and dust, facilitates the stratified interception and collection of mud, and can automatically backwash and clean the filter holes of the filter structure to avoid filter hole blockage affecting the filtration effect, thus solving the problems mentioned in the background art.

The two sets of backwash nozzles are respectively positioned corresponding to the front and rear filter plates.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] In this invention, construction dust and fumes are introduced from the bottom of the spray tower and guided and dispersed by multiple sets of turbine blades, resulting in a more uniform airflow distribution. The airflow is then guided and dispersed by the guide groove at the top of the guide plate, and the atomized water sprayed from the atomizing nozzles sprays and captures the dust. The dust and water mist combine to form slurry that falls and is collected on the slurry receiving plate. By setting multiple sets of guide plates inside the spray tower, the construction waste dust and fumes can be sprayed and captured step by step from bottom to top, forming multiple zones of dust slurry, which effectively improves the adequacy of dust treatment, reduces the amount of dust residue in the exhaust gas after treatment, and meets the requirements of energy-saving and environmentally friendly treatment.

[0025] In this invention, a rodless cylinder drives a sliding plate to slide up and down along a groove. During the sliding process, the positioning gear on the transmission shaft moves along the meshing positioning rack, causing the transmission shaft to rotate. The transmission shaft drives the driven bevel gear to rotate through the meshing active bevel gear, which in turn drives the guide plate to rotate synchronously, improving the uniformity of the flow and spray. This allows multiple sets of guide plates to slide up and down and rotate, forming turbulence in the water mist sprayed by the atomizing nozzle, which combines more fully with the rising dust and smoke, improving the dust capture effect.

[0026] In this invention, the transmission rod moves up and down synchronously with the slide plate. The transmission rod drives the positioning block to rotate synchronously through the spiral groove. This causes the positioning block to drive multiple sets of connecting plates to rotate and scrape the material along the surface of the mud receiving plate. The mud on the mud receiving plate is pushed outward along the conical surface of the mud receiving plate by the scraping action of the trapezoidal scraper, and is discharged at the mud inlet. Since the filter holes in the filter components in the same circumferential plane are of different sizes, the mud is driven from one set of filter components to another set of filter components. This can filter and discharge the particles in the mud according to their size, effectively improving the efficiency of mud separation and filtration, and reducing the residual accumulation of mud inside the device.

[0027] In this invention, when exporting construction waste slurry from different zones in the spray tower, the guide plates in multiple sets of sealing gates are rotated, separating the sealing plates from the corresponding slurry outlets. As the trapezoidal scraper moves the corresponding filter components back and forth along the annular groove through the connecting plate, the front and rear filter plates in the corresponding filter components push and pull the corresponding piston rods to compress the air inside the air storage tank. The compressed air in the air storage tank is transported to the backwash nozzle through the connecting air pipe. The backwash nozzle sprays out the compressed air to backwash and clean the filter holes of the corresponding front and rear filter plates, effectively preventing the filter holes from becoming clogged and ensuring the continuous and smooth operation of the filtration process.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Example 1:

[0039] This embodiment provides an energy-saving and environmentally friendly treatment device for construction waste, such as... Figures 1-8 As shown, it includes a spray tower 100, and also includes:

[0040] Sealing gates 200 are installed at equal intervals on the outside of the spray tower 100. The sealing gates 200 include guide plates 21. The sealing gates 200 are used to guide the construction dust and slurry that are atomized in sections inside the spray tower 100.

[0041] The mud receiving plate 300 is fixedly installed at equal intervals in the inner wall of the spray tower 100. A connecting plate 31 is attached to the top of the mud receiving plate 300. The mud receiving plate 300 is used to receive the atomized construction dust mud.

[0042] Turbine blades 400 are installed at equal intervals in the inner wall of the spray tower 100. A first connecting frame 41 is provided on the outside of the turbine blades 400. The turbine blades 400 are used to guide and transport building dust inside the spray tower 100.

[0043] A reciprocating drive assembly 500 is installed at equal intervals in the inner wall of the spray tower 100. The reciprocating drive assembly 500 includes a fixing frame 51 and is used to reciprocate the transmission of the supporting components inside the spray tower 100.

[0044] The guide plates 600 are installed at equal intervals in the inner wall of the spray tower 100. The guide plates 600 are used to guide the construction dust inside the spray tower 100.

[0045] A synchronous rotating assembly 700 is installed on the top of the corresponding mud receiving plate 300. The synchronous rotating assembly 700 includes a positioning block 71. The synchronous rotating assembly 700 is used to reciprocate the corresponding connecting plate 31. A second connecting frame 712 is fixedly installed at the center of the top of the mud receiving plate 300. A ring sleeve 711 is fixedly installed on the top of the second connecting frame 712. The positioning block 71 is rotatably installed in the inner wall of the corresponding ring sleeve 711. Ear plates 713 are fixedly installed at equal intervals on the top circumference of the positioning block 71. One end of the ear plate 713 is fixedly connected to one end of the corresponding connecting plate 31. The transmission rod 56 drives the positioning block 71 to reciprocate synchronously through the spiral groove 561, so that the positioning block 71 drives multiple sets of connecting plates 31 to reciprocate along the surface of the mud receiving plate 300 to scrape the material. The mud slurry received on the mud receiving plate 300 is pushed outward along the conical surface of the mud receiving plate 300 under the scraping action of the trapezoidal scraper 32 and collected and discharged at the mud guide port 141.

[0046] The spray tower 100 has a dust gas pipe 11 fixedly installed through its bottom. A demister 12 is fixedly installed at the top opening of the spray tower 100. A sludge pump 13 and a suction nozzle 131 are fixedly installed on the bottom of the spray tower 100 away from the dust gas pipe 11. The opening end of the suction nozzle 131 extends to the bottom of the inner cavity of the spray tower 100. The input end of the sludge pump 13 is connected and fixedly connected to the slurry outlet of the suction nozzle 131. Mud guide plates 14 are fixedly installed at equal intervals on the outer circumference of the spray tower 100. Mud guide ports 141 are opened through the outer circumference of the spray tower 100 at equal intervals. Annular grooves 142 are opened in the inner wall of the multiple mud guide ports 141 located on the same circumferential surface.

[0047] This design is for reference. Figures 1-3 The dust and fumes generated after the construction waste is crushed are introduced from the bottom of the spray tower 100 through the dust duct 11. The dust-laden airflow is guided by multiple sets of turbine blades 400 as it flows upward.

[0048] The guide plate 21 has a U-shaped structure and slides outside the corresponding backwash nozzle 82. One end of the inner wall of the guide plate 21 is integrally formed with a sealing plate 22. Each set of sealing plates 22 is located between two sets of corresponding backwash nozzles 82, and the sealing plate 22 is sealed and connected to the outside of the corresponding mud guide port 141.

[0049] This design is for reference. Figures 2-4When exporting construction waste slurry from different zones in the spray tower 100, the sealing plate 22 is separated from the corresponding mud outlet 141 by rotating the guide plate 21 in the multiple sets of sealing gates 200.

[0050] The mud receiving plate 300 has an isosceles trapezoidal structure in its side section. Multiple sets of connecting plates 31 are arranged in a circular pattern at equal intervals on the top of the corresponding mud receiving plate 300. Trapezoidal scrapers 32 are integrally formed on both sides of the connecting plate 31. A connecting plate 33 is fixedly installed at the outer edge of the connecting plate 31. The first connecting frame 41 is fixedly installed in the inner wall of the spray tower 100. The turbine blade 400 is rotatably installed at the center of the top of the corresponding first connecting frame 41.

[0051] This design is for reference. Figures 2-4 As the dust-laden airflow moves upward, it is guided and dispersed by multiple sets of turbine blades 400, resulting in a more uniform airflow distribution. Subsequently, the airflow is further dispersed by the guide groove 61 at the top of the guide plate 600, and the atomized water sprayed from the atomizing nozzle 62 sprays and captures the dust. The dust and water mist combine to form slurry that falls onto the mud receiving plate 300 for collection. With multiple sets of guide plates 600 installed inside the spray tower 100, the dust and smoke from construction waste can be captured by spraying from bottom to top in stages, forming dust slurry in multiple zones. This effectively improves the adequacy of dust treatment and reduces the amount of dust residue in the exhaust gas after treatment.

[0052] The fixing frame 51 is fixedly installed in the inner wall of the spray tower 100. A positioning rack 52 and a rodless cylinder 53 are fixedly installed on the outer circumference of the spray tower 100. A sliding plate 54 is slidably connected to the inner wall of the fixing frame 51. A drive shaft 55 is rotatably installed at one end of the sliding plate 54. A drive rod 56 is movably connected through the top of the fixing frame 51. Slide grooves 511 are respectively opened through both ends of the fixing frame 51. The slide groove 511 near the positioning rack 52 extends to the outside of the spray tower 100. The sliding plate 54 slides in the inner wall of the slide groove 511. Corrugated metal blocks 512 are fixedly installed between the top and bottom of the sliding plate 54 and the inner wall of the slide groove 511. Guide grooves are respectively opened on both sides of the inner wall of the slide groove 511 outside the spray tower 100. Corrugated metal block 512 has sliding pins fixedly installed at equal intervals at both ends. Corrugated metal block 512 slides in the corresponding guide groove through the sliding pins. Device groove 541 is opened through the middle of the bottom surface of slide plate 54. Drive shaft 55 is rotatably installed in the inner wall of device groove 541. Positioning gear 551 and driving bevel gear 552 are fixedly installed at both ends of drive shaft 55. The bottom end of drive rod 56 is fixedly connected to the top of corresponding slide plate 54. Driven bevel gear 563 is rotatably connected to the top of inner wall of device groove 541 through rotating shaft. Driven bevel gear 563 meshes with corresponding driving bevel gear 552. Positioning gear 551 meshes with corresponding positioning rack 52. The end of slide plate 54 near positioning rack 52 is fixedly connected to the movable end of rodless cylinder 53.

[0053] This design is for reference. Figures 5-6 The rodless cylinder 53 drives the slide plate 54 to slide up and down along the slide groove 511. The corrugated metal block 512 slides synchronously in the corresponding guide grooves on both sides of the inner wall of the slide groove 511 through the sliding pins evenly distributed at both ends. In this way, when the slide plate 54 slides up and down, the corrugated metal block 512 can be compressed or stretched synchronously, which can block the sliding opening of the slide groove 511 and effectively prevent dust from falling into the gap of the slide groove and affecting the sliding operation. During the sliding process, the positioning gear 551 on the drive shaft 55 moves along the meshing positioning rack 52, which drives the drive shaft 55 to rotate. The drive shaft 55 drives the driven bevel gear 563 to rotate through the meshing active bevel gear 552, which in turn drives the guide plate 600 to rotate synchronously, improving the uniformity of the guide and spray. This makes the multiple sets of guide plates 600 slide and rotate up and down, forming a turbulent flow of water mist sprayed by the atomizing nozzle 62, which combines more fully with the rising dust and smoke, improving the dust capture effect.

[0054] The guide plate 600 is fixedly installed on the bottom end of the shaft of the corresponding driven bevel gear 563. Guide grooves 61 are evenly spaced through the top conical surface of the guide plate 600. An atomizing nozzle 62 is fixedly installed at the bottom of the guide plate 600. A connecting pipe 621 is fixedly installed at the top of the atomizing nozzle 62. The connecting pipe 621 extends movably through the transmission rod 56 to the outside of the spray tower 100. A second connecting frame 712 is fixedly installed at the center of the top of the mud receiving plate 300. A ring sleeve 711 is fixedly installed at the top of the second connecting frame 712. A positioning block 71 is rotatably installed in the inner wall of the corresponding ring sleeve 711. Ear plates 71 are evenly spaced on the top circumference of the positioning block 71. 3. One end of the ear plate 713 is fixedly connected to one end of the corresponding connecting plate 31. The outer side of the transmission rod 56 and the inner diameter of the positioning block 71 are respectively provided with spiral grooves 561. The transmission rod 56 is slidably connected to the corresponding positioning block 71 through the spiral grooves 561. Corrugated dustproof sleeves 562 are movably sleeved at the upper and lower positions of each group of transmission rods 56. The bottom end of the corrugated dustproof sleeve 562 at the top of the transmission rod 56 is rotatably connected to the top of the positioning block 71. The top end of the corrugated dustproof sleeve 562 at the top of the transmission rod 56 is fixedly connected to the top end of the transmission rod 56. The two ends of the corrugated dustproof sleeve 562 at the bottom of the transmission rod 56 are respectively fixedly installed between the corresponding second connecting frame 712 and the fixed frame 51.

[0055] This design is for reference. Figures 4-7The transmission rod 56 moves up and down synchronously with the slide plate 54. The transmission rod 56 drives the positioning block 71 to rotate synchronously through the spiral groove 561. This causes the positioning block 71 to drive multiple sets of connecting plates 31 to rotate and scrape the material along the surface of the mud receiving plate 300. The mud received on the mud receiving plate 300 is pushed outward along the conical surface of the mud receiving plate 300 by the scraping action of the trapezoidal scraper 32, and is discharged at the mud inlet 141. Since the filter holes in the filter components 900 are of different sizes in the same circumferential plane, the mud is driven from one set of filter components 900 to another set of filter components 900. This can filter and discharge the particles in the mud according to their size, effectively improving the efficiency of mud separation and filtration, and reducing the residual accumulation of mud inside the device.

[0056] Example 2:

[0057] Based on Example 1, this example provides an energy-saving and environmentally friendly treatment device for construction waste, such as... Figures 3-8 As shown, it includes:

[0058] The gas storage assembly 800 is installed at equal intervals on the circumference of the spray tower 100. The gas storage assembly 800 includes a gas storage cylinder 81 and a backwash nozzle 82. The gas storage assembly 800 is used to backwash and clean the filter screen and filter holes on the circumference of the spray tower 100.

[0059] The filter assembly 900 is installed at equal intervals on the circumference of the spray tower 100. The filter assembly 900 includes a front filter plate 91 and a rear filter plate 92. The filter assembly 900 is used to filter the construction dust and slurry after it is atomized in the spray tower 100.

[0060] In this configuration, one end of each set of piston rods 811 is fixedly connected to the ends of the corresponding front filter plate 91 and rear filter plate 92, respectively. The air storage cylinder 81 is fixedly installed in the inner wall of the corresponding annular groove 142, and the backwash nozzle 82 is fixedly inserted through the inner wall of the corresponding annular groove 142. The piston rod 811 is slidably connected inside the air storage cylinder 81, and a return spring 812 is fixedly installed between the piston rod 811 and the end of the air storage cylinder 81. A connecting air pipe 813 is fixedly connected between the one-way valve at the air outlet of the tail end of the air storage cylinder 81 and the backwash nozzle 82.

[0061] This design is for reference. Figure 5 and Figure 8 When the construction waste slurry in different zones of the spray tower 100 is discharged, the guide plate 21 in the multiple sets of sealing gates 200 is rotated, the sealing plate 22 is separated from the corresponding mud guide port 141, and the trapezoidal scraper 32 moves the corresponding filter component 900 back and forth along the annular groove 142 through the connecting plate 33. The front filter plate 91 and the rear filter plate 92 in the corresponding filter component 900 push and pull the corresponding piston rod 811 to squeeze the air inside the air storage cylinder 81.

[0062] Among them, the arc length of the front filter plate 91 and the rear filter plate 92 is equal to the arc length of the corresponding mud guide port 141. The bottom of the connecting plate 33 away from the trapezoidal scraper 32 is fixedly installed at the top edge of the connection between the front filter plate 91 and the rear filter plate 92. The front filter plate 91 and the inner wall of the corresponding annular groove 142 are in clearance fit. The two sets of backwash nozzles 82 are respectively corresponding to the positions of the front filter plate 91 and the rear filter plate 92.

[0063] This design is for reference. Figure 4 , Figure 5 and Figure 8 Compressed air in the air storage tank 81 is delivered to the backwash nozzle 82 through the connecting air pipe 813. The backwash nozzle 82 sprays out compressed air to backwash and clean the filter holes of the corresponding front filter plate 91 and rear filter plate 92, effectively preventing the filter holes from becoming clogged and ensuring the continuous and smooth operation of the filtration operation. When the positioning block 71 moves away from the piston rod 811, the piston rod 811 is reset under the action of the return spring 812, completing the air intake replenishment of the air storage tank 81 and preparing for the next backwash operation. The entire process can automatically complete the filter hole cleaning without the need for an additional power source.

[0064] Working principle: When this energy-saving and environmentally friendly construction waste treatment device is in use, the dust and smoke generated after the construction waste is crushed are introduced from the bottom of the spray tower 100 through the dust gas pipe 11. During the upward flow, the dust and smoke are guided and dispersed by multiple sets of turbine blades 400 in sequence, making the airflow distribution more uniform. Then the airflow is guided and dispersed by the guide groove 61 at the top of the guide plate 600. The atomized water sprayed by the atomizing nozzle 62 sprays and captures the dust. The dust and water mist combine to form mud and fall onto the mud receiving plate 300 for collection.

[0065] When dust and smoke are introduced into the spray tower 100, the rodless cylinder 53 drives the slide plate 54 to slide up and down along the slide groove 511. During the sliding process, the positioning gear 551 on the drive shaft 55 moves along the meshing positioning rack 52, causing the drive shaft 55 to rotate. The drive shaft 55 drives the driven bevel gear 563 to rotate through the meshing active bevel gear 552, which in turn drives the guide plate 600 to rotate synchronously, improving the uniformity of the guide and spray. This causes multiple sets of guide plates 600 to slide up and down and rotate, forming turbulence from the water mist sprayed by the atomizing nozzle 62, which combines more fully with the rising dust and smoke, improving the dust capture effect. The drive rod 56 rises synchronously with the slide plate 54. The transmission rod 56 drives the positioning block 71 to rotate synchronously through the spiral groove 561, which causes the positioning block 71 to drive multiple sets of connecting plates 31 to rotate and scrape the material along the surface of the mud receiving plate 300. The mud received on the mud receiving plate 300 is pushed outward along the conical surface of the mud receiving plate 300 by the scraping action of the trapezoidal scraper 32, and is discharged at the mud inlet 141. Since the filter hole size in the filter assembly 900 in the same circumferential plane is different, the mud is driven from one set of filter assembly 900 to another set of filter assembly 900. In this way, the particles in the mud can be classified and filtered out according to the particle size, which can effectively improve the efficiency of mud separation and filtration and reduce the residual accumulation of mud inside the device.

[0066] When discharging construction waste sludge from different zones in the spray tower 100, the guide plates 21 in the multiple sets of sealing gates 200 are rotated, and the sealing plates 22 are separated from the corresponding sludge guide ports 141. As the trapezoidal scraper 32 moves the corresponding filter assembly 900 back and forth along the annular groove 142 through the connecting plate 33, the front filter plate 91 and the rear filter plate 92 in the corresponding filter assembly 900 push and pull the corresponding piston rods 811 to compress the air inside the air storage cylinder 81. The compressed air in the air storage cylinder 81 is then discharged through the connecting air pipe. 813 is conveyed to the backwash nozzle 82, which sprays compressed air to backwash and clean the filter holes of the corresponding front filter plate 91 and rear filter plate 92, effectively preventing the filter holes from becoming clogged and ensuring the continuous and smooth operation of the filtration operation. When the positioning block 71 moves away from the piston rod 811, the piston rod 811 is reset under the action of the return spring 812, completing the air intake of the air storage tank 81 and preparing for the next backwash operation. The entire process can automatically complete the filter hole cleaning without the need for an additional power source.
