Description

Technical Field

[0001] This invention relates to the field of construction waste treatment equipment technology, specifically an environmentally friendly construction waste resource recovery device. Background Technology

[0002] Construction waste recycling refers to the harmless and resource-oriented processing of construction waste such as concrete, bricks, mortar, and slag generated during house demolition, construction, and decoration. This is achieved through processes such as crushing, screening, impurity removal, washing, and solid-liquid separation. Solid waste that was originally difficult to dispose of is transformed into reusable building materials such as recycled aggregates, recycled bricks, recycled concrete, and road base materials. This process reduces waste volume, promotes resource utilization, and renders the waste harmless. This method can effectively reduce the land occupation and environmental pollution caused by construction waste landfill, conserve natural sand and gravel resources, and promote the green and low-carbon development of the construction industry. It is an important technical means to achieve resource recycling and sustainable development.

[0003] Existing environmentally friendly construction waste recycling facilities generate a large amount of dust during the crushing process. This dust, mostly fine mortar, concrete, and brick particles, easily spreads and disperses within the work area, causing serious environmental pollution, affecting the surrounding air quality, and posing a health hazard to on-site operators. Furthermore, the unorganized dust emissions adhere to the equipment surface, exacerbating mechanical wear and affecting the stable operation of the equipment. In addition, the escape of dust reduces the cleanliness of the plant's working environment, failing to meet the requirements of green and environmentally friendly production, and making it difficult to meet the high standards of energy conservation, emission reduction, and clean production in the current construction solid waste treatment process. Summary of the Invention

A discharge trough 32 is formed through the side of the discharge box 3 away from the water storage tank 4. The bottom of the discharge trough 32 is flush with the lowest point of the top of the separation plate 33. Multiple sets of liquid separating holes are formed through the top of the separation plate 33. The waste and dust-laden wastewater are evenly distributed on the top of the separation plate 33. After the crushed waste and dust-laden wastewater fall onto the separation plate 33, the solid waste moves along the separation plate 33 to the discharge trough 32. The wastewater falls through the liquid separation hole. The bottom of the discharge box 3 is fixedly connected to the guide platform 34. The cross-section of the guide platform 34 is a right triangle with its inclined surface facing upward. The side of the guide platform 34 closest to the water storage tank 4 is the lowest point. The side of the discharge box 3 closest to the water storage tank 4 is provided with a connecting groove 31.

[0027] Reference Figures 6 to 10A connecting groove 41 is provided through the water storage tank 4 on the side near the discharge box 3. The connecting groove 31 and the connecting groove 41 are connected, and the sides of the discharge box 3 and the water storage tank 4 with the connecting grooves 31 and 41 are tightly fitted together, so that the gap between the connecting grooves 31 and 41 is negligible, and the liquid does not leak when passing through the connecting grooves 31 and 41. A dividing plate 42 is fixedly connected inside the water storage tank 4 on the side near the discharge box 3. The dividing plate 42 is in the shape of a "F". The top of the inner side of the connecting groove 41 is flush with the top of the inner side of the dividing plate 42. The bottom of the dividing plate 42 is flush with the inside of the water storage tank 4. There is a gap at the bottom of the interior. Inside the water storage tank 4, inclined plates 43 and 44 are fixedly connected. Inclined plates 43 and 44 are positioned between the dividing plate 42 and the side of the water storage tank 4 furthest from the discharge box 3. The length of inclined plates 43 and 44 is less than the gap between the dividing plate 42 and the side of the water storage tank 4 furthest from the discharge box 3. There is a gap between inclined plate 43 and the side of the water storage tank 4 furthest from the discharge box 3, and a gap exists between inclined plate 44 and the dividing plate 42. Multiple sets of inclined plates 43 and 44 are provided, ensuring that the dividing plate 42 and the side of the water storage tank 4 furthest from the discharge box 3 are connected. A multi-stage baffle channel is created between the components. A sliding groove 45 is provided inside the water storage tank 4, positioned above the dividing plate 42. The sliding groove 45 is U-shaped, with its opening facing away from the discharge box 3. A slot 46 is provided through the water storage tank 4 on the side away from the discharge box 3, and the slot 46 communicates with the sliding groove 45. A filter layer 47 is slidably connected within the sliding groove 45, penetrating the slot 46. A threaded hole 48 is provided on the side of the filter layer 47 facing the slot 46. By installing bolts in the threaded hole 48, the filter layer 47 can be quickly pulled out from the slot 46. An installation groove 49 is provided on the outer side of the water storage tank 4. The installation groove 49 is connected to the slot 46. A T-shaped connecting groove 410 is provided on the inner side of the installation groove 49.

The connecting block 411 is inserted from the connecting groove 410 through one side of the water storage tank 4, so that the baffle 412 is inserted into the installation groove 49 at the same time. When the baffle 412 is inserted, it is flush with the outer side of the water storage tank 4.

[0028] The above scheme employs the following: The connecting channel 2 41 is tightly connected to the connecting channel 1 31 without gaps, ensuring no wastewater leakage. The F-shaped dividing plate 42 can initially guide the incoming wastewater. The multi-stage baffle channel formed by multiple sets of inclined plates 1 43 and 2 44 can shorten the settling distance of sediment particles in the wastewater and accelerate the natural settling speed. The cooperation of the sliding channel 45, slot 46, and filter layer 47 facilitates the quick installation and disassembly of the filter layer 47. The threaded hole 48 facilitates the fixing or disassembly of the filter layer 47 with bolts. The synergistic effect of the mounting slot 49, connecting slot 410, connecting block 411, and baffle 412 can seal the slot 46 to prevent wastewater leakage, while also facilitating the opening of the baffle 412 to disassemble the filter layer 47 for cleaning or replacement, achieving efficient purification and recycling of wastewater.

[0029] The working principle of this invention is as follows: During use, the construction waste to be processed is first fed into the top of the crushing hopper 11. The waste falls between two parallel toothed roller assemblies 12. Under the relative rotation of the roller assemblies 12 and the biting action of the toothed roller surfaces, the waste is squeezed, sheared, and crushed. During this process, the dust suppression component 2 starts simultaneously, and the pump 21 begins operation, drawing clean water from the water storage tank 4 through the water inlet pipe 22. After being pressurized by the pump 21, the clean water is transported to the circulation pipe 24 through the water outlet pipe 23. The O-shaped circulation pipe 24, surrounding the crushing hopper 11, evenly distributes the clean water to multiple sets of spray cylinders 25. The clean water is sprayed into the interior of the crushing hopper 11 through multiple sets of spray holes 26 on the end face of the spray cylinders 25, forming a uniform water mist that quickly adsorbs the dust generated during the crushing process and suppresses dust. Dust dispersion achieves dust suppression. The wastewater after dust suppression, along with the crushed solid particles, falls from the bottom of the crushing hopper 11 into the discharge box 3. The mixture falling into the discharge box 3 lands on the inclined separation plate 33. Since the side of the separation plate 33 closer to the water storage tank 4 is higher and the side farther from the water storage tank 4 is lower, and the bottom of the inner side of the discharge chute 32 is flush with the lowest point of the top of the separation plate 33, the solid waste slides along the separation plate 33 towards the discharge chute 32 under its own gravity, and is finally discharged from the discharge chute 32. The discharged solid waste can be used as raw material for recycled aggregate for further processing. The dust suppression wastewater falls through the multi-component liquid holes at the top of the separation plate 33 to the bottom of the discharge box 3, landing on the inclined surface of the guide platform 34. Since the guide platform 34 is close to the water storage tank... 4. One side is lower, and the bottom of the connecting channel 31 is flush with the lowest point of the top of the guide platform 34. Therefore, the wastewater flows along the inclined surface of the guide platform 34 to the connecting channel 31, and then flows into the water storage tank 4 through the connecting channel 31 and the connecting channel 41, completing solid-liquid separation. The wastewater flowing into the water storage tank 4 first contacts the F-shaped dividing plate 42. The dividing plate 42 initially guides the wastewater, causing it to flow from the gap between the bottom of the dividing plate 42 and the bottom of the water storage tank 4 into the area between the dividing plate 42 and the side of the water storage tank 4 away from the discharge box 3. It then enters the multi-stage baffle channel formed by multiple sets of inclined plates 43 and 44. The wastewater flows back and forth multiple times in the baffle channel, reducing the flow velocity. The solid particles such as mud, sand, and mortar powder carried by the wastewater settle rapidly under the action of gravity, achieving solid-liquid separation. The wastewater undergoes initial purification. After initial purification, the wastewater continues to flow upwards, passing through filter layer 47. Filter layer 47 filters out residual fine impurities in the wastewater, further improving its cleanliness. The filtered clean water remains at the bottom of storage tank 4 and can be pumped again by pump 21. It is then recycled through dust-suppressing component 2 for dust suppression, achieving water resource recycling. After prolonged operation, filter layer 47 accumulates a large amount of impurities, affecting the filtration effect. At this time, baffle 412 can be pulled out of mounting slot 49, causing connecting block 411 to be removed from connecting slot 410, exposing threaded holes 48 on filter layer 47. Then, bolts are connected to filter layer 47 through threaded holes 48. Pulling the bolts pulls filter layer 47 out of slot 46 and sliding groove 45 for cleaning or replacement.After cleaning or replacement, reinsert the filter layer 47 into the sliding groove 45 and slot 46, remove the bolts, and then insert the connecting block 411 into the connecting groove 410, so that the baffle 412 seals the slot 46, allowing for continued use. The entire device achieves integrated operation of construction waste crushing, dust suppression, solid-liquid separation, and wastewater purification and recycling, fully complying with environmental protection requirements and improving the efficiency and environmental friendliness of construction waste resource utilization.
