The cement residue rate is high, resulting in low waste recycling rate. Traditional processes usually directly discharge washing wastewater, which wastes water resources. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Concrete production, as a core component of infrastructure construction, generates a massive amount of waste annually (such as leftover concrete, cleaning wastewater, and solidified waste). Traditional treatment methods (such as direct landfill and simple screening) suffer from low efficiency, heavy pollution, and insufficient resource recovery rates. Waste types include uncured concrete mixtures (transportation residues, mixer remnants containing cement, sand, and water, prone to solidification), cleaning waste (wastewater from mixer truck and equipment cleaning, containing fine sand and cement slurry with high suspended solids concentration), solidified waste (waste concrete blocks and hardened residues, high strength and often containing impurities), and slurry water (waste liquid after water washing and separation, containing fine cement particles and high pH). Traditional treatment methods suffer from drawbacks such as sand and gravel recovery rates below 60%, low water resource reuse rates, violations of emission standards, landfill space requirements for solid waste, and high costs for aggregate procurement and waste treatment. Therefore, developing efficient waste separation devices is crucial for the concrete industry to achieve green production. These devices can not only recycle sand, gravel, and water resources, reducing production costs, but also help companies meet environmental policy requirements.

[0022] From the perspective of technological evolution, before the 1990s, manual screening or simple vibrating screens were used to process uncoagulated waste. This could only separate large particles of sand and gravel, and the mud and water were directly discharged. Coagulated waste relied on manual crushing, which was inefficient, did not remove impurities thoroughly, and resulted in insufficient purity of recycled aggregates. From 2000 to 2010, equipment such as spiral sand washing machines and drum screens were introduced to achieve a combination of screening and washing, increasing the sand and gravel recovery rate to 70%-80%. Sedimentation tanks and filter presses were used to treat mud and water in combination, and some clean water was reused, but the degree of automation was low. After 2010, integrated equipment that integrates crushing, screening, washing, dewatering, and mud treatment processes was introduced. PLC control systems were introduced to achieve automatic adjustment, and AI visual recognition technology was used for impurity sorting, and drone inspection devices were used to monitor the amount of waste stockpiled.

[0023] Currently, regarding the core types and technical characteristics of waste separation devices, mechanical screening devices consist of vibrating screens, conveyor belts, hoppers, etc., which mechanically separate sand and gravel using the screen mesh size. They are low-cost, simple to maintain, and suitable for small mixing plants. However, they cannot remove cement slurry from the surface of sand and gravel, and the recovered aggregate has a high mud content, requiring additional treatment of the mud slurry. Hydraulic cleaning integrated devices have core components including spiral sand washing machines and sedimentation tanks. They first screen waste materials, and after washing sand and gravel, the mud slurry is reused after sedimentation. The bottom mud slurry is pressed into cakes, reducing the mud content of sand and gravel to below 1%, and the water resource recycling rate exceeds 80%. They are suitable for medium-sized mixing plants. Intelligent integrated processing systems integrate crushing modules, high-frequency vibrating screens, etc. The high-frequency vibrating screen has high screening accuracy, and countercurrent water washing reduces cement slurry residue and energy consumption. The intelligent system can automatically adjust the water washing volume and generate data reports, with strong processing capacity, making it suitable for large mixing plants or precast component plants.

[0024] In terms of practical application value and benefits, environmentally, processing 10,000 tons of waste can reduce solid waste landfill by 6,000 tons and save about 100 square meters of land. Medium-sized mixing plants can save more than 100,000 tons of water and reduce sewage discharge fees by about 100,000 yuan per year. Economically, processing 100,000 tons of waste per year can save 3 million yuan in aggregate costs, and the sludge cake after filtration can be used as raw material for brick making to generate revenue. Socially, it helps enterprises pass the "green building materials certification" and promotes the industry's transformation towards "zero emissions".

[0025] However, current applications of these devices still face challenges such as cost barriers (high initial investment for integrated equipment, low willingness to purchase by small and medium-sized enterprises), technological bottlenecks (fine sand recovery rate less than 50%, difficulty in efficiently separating trace cement particles from mud and water), and maintenance difficulties (prone to scaling in the washing system, short component lifespan). Future development directions include developing solar-powered, low-carbon, small-scale separation devices; introducing magnetic separation and nanofiltration membranes to achieve refined full-component recovery; creating vehicle-mounted mobile equipment; and connecting to industrial internet platforms for digital management. In short, technological innovation in concrete waste separation devices is key to overcoming the industry's environmental challenges and achieving resource recycling. Future development will focus on "full-component recovery, zero-energy processing, and intelligent operation and maintenance." When selecting a device, companies need to comprehensively consider production capacity, environmental standards, and investment budget to achieve a win-win situation for both environmental and economic benefits.

[0030] Please see Figure 6 In this embodiment, the circulation mechanism 5 includes a first funnel block 51, a second funnel block 52, a sedimentation tank 53, a filter screen 54, and a sixth slot 55.

The output end of the first electric cylinder 42 drives the bottom plate 43 to move, removing the bottom plate 43 and the support plate 46 from the inside of the storage box 1. The material and mud on the upper end of the support plate 46 fall into the inside of the sedimentation box 53 through the second funnel block 52. The mud and water inside the sedimentation box 53 are filtered through the filter screen 54. The filtered water flows into the inside of the water tank 31 through the connecting pipe 34 for reuse.
