Description

Technical Field

[0001] The invention relates to the technical field of construction waste treatment, and in particular to a construction waste treatment device for civil engineering. Background Art

[0002] With the acceleration of urbanization, the scale of waste generated by building demolition and renovation projects has been increasing year by year. Traditionally, waste is directly landfilled or crushed after screening for preparation as recycled aggregate. However, due to the complex composition of waste, lightweight non-metallic impurities such as wood chips and plastics will significantly reduce the strength of recycled materials and cause resource waste. Therefore, efficient separation of impurities has become a key pre-link for the resource utilization of construction waste.

[0003] In order to improve the resource utilization efficiency of construction waste, the industry has developed a series of processing processes, including screening out fine slag dust, air-selecting ultra-light materials, manually selecting wood and plastic pipes, crushing with jaw crushers, separating metal parts with electromagnetic iron removers, and screening out aggregates of specific particle sizes again. However, these processing processes still have some problems. In particular, the treatment of non-magnetic lightweight impurities such as wood and plastic pipes is still highly dependent on manual sorting. This manual sorting method has many disadvantages: first, the working environment is poor, posing a potential threat to the health of workers; second, manual sorting is inefficient and difficult to meet the needs of large-scale waste treatment; finally, manual sorting is prone to missed inspections, affecting the final treatment effect.

[0028] Embodiment, a waste treatment device for civil engineering construction, such as Figures 1 to 4As shown, it includes a moving water pool 1, in which a chain plate conveyor 2 facing left and right is provided, the left end of the chain plate conveyor 2 is horizontally arranged in the moving water pool 1, and the right end of the chain plate conveyor 2 is tilted upward and extends to the outside of the moving water pool 1. A recovery component 3 for collecting floating objects is provided in the middle of the moving water pool 1, and the recovery component 3 includes a net chain conveyor 31, a first support rod 32, a discharge trough 33 and a second support rod 34. The left end of the net chain conveyor 31 extends below the water surface, and the right end tilts upward. The upper end of the first support rod 32 is connected to the right end of the net chain conveyor 31, and the lower end is connected to the moving water pool 1. The discharge trough 33 is arranged below the right side of the net chain conveyor 31, and the lower end of the discharge trough 33 extends to the outside of the moving water pool 1 and is connected to the moving water pool 1 through the second support rod 34. The chain conveyor 2 in the moving water pool 1 is used to transport waste materials. The right end of the chain conveyor 2 is tilted to the outside of the moving water pool 1, so that the waste materials can be transported from the moving water pool 1 to the outside. The recovery component 3 in the middle of the moving water pool 1 is used to collect floating objects. The left end of the net chain conveyor 31 extends below the water surface, which can effectively collect floating objects in the water. The right end of the net chain conveyor 31 is tilted upward and fixed by the first support rod 32 to ensure stable operation. The discharge trough 33 is arranged at the lower right side of the net chain conveyor 31 and is connected to the moving water pool 1 through the second support rod 34, so that the collected floating objects can be discharged from the moving water pool 1 smoothly. The entire device can efficiently separate floating impurities in waste materials through the cooperation of the chain conveyor 2 and the net chain conveyor 31.

[0029] A still water pool 4 is provided on the right side of the chain conveyor 2. The chain conveyor 2 extends above the still water pool 4. The right end of the chain conveyor 2 extends to the right side of the still water pool 4. The chain conveyor 2 is connected to the still water pool 4 through a third support rod 41. An air dryer 5 is provided above the chain conveyor 2. A fourth support rod 51 is connected to the circumference of the air dryer 5. The lower end of the fourth support rod 51 is connected to the still water pool 4. The width of the still water pool 4 is greater than the width of the chain conveyor 2.

[0030] Through the cooperation of the chain conveyor 2 and the still water pool 4, the waste can be transported to the top of the still water pool 4 for drainage, and the waste is dried by the air dryer 5, allowing the water to flow into the still water pool 4. The width of the still water pool 4 is greater than the width of the chain conveyor 2, so that the water in the dynamic water pool 1 can be passed into the still water pool 4 for sedimentation after being used for a period of time. The larger width makes it easier to clean the mud and sand at the bottom.

[0031] The inverted V-shaped design of the discharge chute 33 and the downwardly facing front and rear ends can provide greater flexibility and convenience during the installation process, and can also discharge waste materials from the dynamic water tank 1 more smoothly during the discharge process.

[0032] A first water inlet pipe 11 is provided at the left end of the moving water pool 1, and a first drain pipe 12 is provided at the right end of the moving water pool 1. The first drain pipe 12 is connected to a first water pump 13. The water outlet of the first water pump 13 is connected to a solenoid valve 14. The solenoid valve 14 is connected to a first connecting pipe 15 and a second connecting pipe 16. The other end of the first connecting pipe 15 is connected to the left end of the moving water pool 1, and the other end of the second connecting pipe 16 is connected to the left end of the still water pool 4.

[0033] The left end of the moving water pool 1 is provided with a first water inlet pipe 11 and the right end is provided with a first drain pipe 12, and these two pipes are connected by a first water pump 13 and a solenoid valve 14 to form a water circulation system. The first connecting pipe 15 and the second connecting pipe 16 respectively introduce and discharge water from the left end of the moving water pool 1 and the left end of the still water pool 4. Through this arrangement, water can circulate between the moving water pool 1 and the still water pool 4, thereby effectively treating waste and reducing the waste of water resources.

[0034] The right end of the still water pool 4 is connected to a first sewage outlet 42, and an openable first cover 43 is provided at the first sewage outlet 42. A pumping assembly 6 is provided in the still water pool 4, and the pumping assembly 6 includes a slide rod 61, a floating block 62, a counterweight block 63, a second drainage pipe 64, a second water pump 65 and a second water inlet pipe 66. Two slide rods 61 are provided and are symmetrically arranged vertically in the still water pool 4 front and back. The floating block 62 is slidably connected to the slide rod 61, and the lower end of the floating block 62 is connected to the counterweight block 63. The counterweight block 63 does not affect the floating block 62 floating on the water surface. The second drainage pipe 64 is a flexible pipe, one end of the second drainage pipe 64 is arranged on the floating block 62, and the other end of the second drainage pipe 64 is connected to the second water pump 65, one end of the second water inlet pipe 66 is connected to the second water pump 65, and the other end of the second water inlet pipe 66 is connected to the left end of the moving water pool 1.

[0035] The first sewage outlet 42 and the openable first cover 43 are used to discharge sewage from the still water pool 4. The pumping assembly 6 keeps the floating block 62 on the water surface through the cooperation of the slide bar 61 and the floating block 62, so that the second drain pipe 64 is always located below the water surface to ensure that the extracted water is relatively clean. The function of the counterweight block 63 is to maintain the stability of the floating block 62 and also to serve as a contact object. When reaching the mud layer, the counterweight block 63 no longer moves downward. The second drain pipe 64 is a flexible pipe, which makes the pumping process more flexible. The second water pump 65 transports clean water back to the water pool 1 through the second water inlet pipe 66, thereby realizing the recycling of water. The counterweight block 63 can be made of different materials and shapes, such as a metal block or a plastic block, depending on the buoyancy of the floating block 62 and the required stability. The second drain pipe 64 can be made of different flexible materials, such as a rubber tube or a plastic tube, to ensure its flexibility and durability in water. The slide bar 61 can be made of stainless steel or other corrosion-resistant materials to ensure its long-term use in water. The buoyancy block 62 may be made of foam plastic or other buoyancy materials to ensure its stability and durability on the water surface.

[0036] A plurality of front-to-rear facing cross bars 17 are provided at the lower end of the chain conveyor 2 in the moving water pool 1. The cross bars 17 are used to support the chain conveyor 2. A chute 18 connected to the inside of the moving water pool 1 is provided at the front end of the moving water pool 1. The rear end of the chute 18 extends to the rear end inner wall of the moving water pool 1. The left and right sides of the chute 18 pass through the cross bars 17 front and back. A baffle 7 is slidably connected in the chute 18. The baffle 7 can separate the moving water pool 1 into two upper and lower cavities. A water retaining strip 71 is provided at the upper end of the baffle 7 outside the moving water pool 1. The water retaining strip 71 is used in conjunction with the front end of the chute 18. Second sewage outlets 19 are provided on both sides of the moving water pool 1. An openable second cover 110 is provided at the second sewage outlet 19.

[0037] The cross bar 17 is used to support the chain conveyor 2 to ensure its stable operation in the dynamic water pool 1. The design of the chute 18 allows the baffle 7 to slide flexibly, thereby separating the dynamic water pool 1 into two upper and lower cavities, which is convenient for separating waste materials at different processing stages. The water retaining bar 71 is used in conjunction with the front end of the chute 18 to effectively prevent water from overflowing. The design of the second sewage outlet 19 and the openable second cover 110 facilitates the discharge and cleaning of the silt in the dynamic water pool 1, ensuring the cleanliness and normal operation of the dynamic water pool 1.

[0038] A partition plate 8 is provided on the left side of the still water pool 4. A plurality of through holes 81 are provided on the partition plate 8, which can effectively prevent larger floating objects from moving to the left.

[0039] Guide plates 9 are provided on both the front and rear sides of the left end of the mesh chain conveyor 31. The provision of the guide plates 9 helps to guide the water flow to a specific direction, avoiding the influence of the water flow on the mesh chain conveyor 31, thereby improving the separation effect and the stability of the equipment. By providing the guide plates 9 on both the front and rear sides of the left end of the mesh chain conveyor 31, the problem of unstable water flow is solved, ensuring the high efficiency and stability of the equipment in separating light impurities.

[0040] Operation process: 1. Screen the construction waste first to screen out fine slag and dust, which can reduce the pollution of subsequent water. 2. Use wind to select ultra-light materials, such as plastic bags, woven bags, cloth and other garbage; although these materials will float on the water, they are not easy to dry and are not convenient for subsequent recycling. 3. Pass the device to screen out lightweight materials such as wood and plastic pipes; wood and plastic pipes can be recycled again. 4. The jaw crusher crushes the construction waste; it can crush it and separate metal parts such as steel bars. Since it was soaked in the previous step, this step is not easy to generate dust. 5. The electromagnetic iron remover separates the metal parts and removes the steel bars; 6. Screen out aggregates of a specific particle size again for easy reuse.
