Description

Technical Field

[0001] This application relates to the field of classification, screening and recycling devices, and in particular to a classification, screening and recycling device for concrete waste. Background Technology

[0002] The construction industry generates a massive amount of concrete waste. With the acceleration of urbanization and the continuous development of construction projects, how to effectively dispose of this concrete waste has become an urgent problem to be solved.

[0003] In the traditional concrete waste treatment process, the automation level of each link from sorting to screening to recycling is generally low. Most of the work relies on manual operation, which is not only labor-intensive but also prone to human error. In the waste transportation process, it is difficult to ensure uniform and stable transportation by manually controlling the transportation speed and direction, which in turn affects the efficiency and quality of the entire treatment process.

[0004] Therefore, a new approach is needed to solve this problem. Utility Model Content

[0005] The purpose of this application is to provide a concrete waste sorting, screening and recycling device, which has the advantages of improving the degree of automation. It solves the problem that the existing work relies on manual operation, which is not only labor-intensive but also prone to human error. In the process of waste transportation, it is difficult to ensure uniform and stable transportation by manually controlling the transportation speed and direction, thus affecting the efficiency and quality of the entire process.

[0006] The concrete waste sorting, screening, and recycling device provided in this application adopts the following technical solution: It includes a box body, with several support rods inserted into the inner wall of the box body. Several grid plates are provided inside the box body, and the inner wall of each grid plate is inserted into a corresponding support rod. Several first discharge ports are opened on the outer surface of the box body. Two fixed frames are provided on the outer side of the box body. A transmission mechanism is fixedly installed on the inner wall of each fixed frame. A connecting rod is fixedly connected to the outer surface of each transmission mechanism. A transmission wheel is fixedly connected to the outer surface of each connecting rod. A transmission belt is provided on the outer side of the box body, and the outer surface of each transmission wheel is connected to the transmission belt. A servo motor is fixedly installed on the outer surface of one of the fixed frames, and the output end of the servo motor is fixedly connected to one of the transmission mechanisms. A vibration motor is fixedly installed on the outer surface of the box body.

[0007] By adopting the above technical solution, the grating is first placed in a designated position inside the box, and then fixed by inserting support rods into the corresponding grating. The material to be screened is then poured into the box, and the vibration motor is started. The box drives the grating to vibrate, and the material is stratified during vibration. During this process, materials of the correct size fall through the gaps in the grating at different positions from the corresponding first discharge port into the conveyor belt below. At the same time, the servo motor is started. The servo motor drives the transmission wheel to rotate through the transmission mechanism and connecting rod. The transmission wheel drives the transmission belt to rotate, so that the transmission mechanisms on both sides operate synchronously. In this way, the material falling from the discharge port is transported to the designated position. Waste materials of different particle size ranges fall into different collection tanks through their respective first discharge ports, realizing preliminary particle size classification. The setting of servo motors and vibration motors can greatly improve the automation level of the equipment.

[0008] Preferably, a magnetic separator is fixedly connected to the outer surface of each of the fixed frames, a magnetic block is fixedly installed on the outer surface of each of the magnetic separators, a magnetic roller is fixedly connected to the output end of each of the magnetic blocks, a scraper is fixedly connected to the inner wall of each magnetic separator, and the outer surface of each scraper is slidably connected to the corresponding magnetic roller.

[0009] By adopting the above technical solution, the waste material after preliminary screening by the vibrating screen is conveyed to the magnetic separator by the conveyor belt. At this time, the magnetic force is output to the magnetic drum by the setting of magnetic blocks. When the waste material containing magnetic materials such as steel bars passes near the magnetic drum, the steel bars are attracted to the surface of the magnetic drum by the magnetic field. As the magnetic drum rotates, the steel bars are carried to the other side. The attracted steel bars are scraped off by the action of the scraper and fall into the collection area of ​​the magnetic separator after leaving the conveyor belt, thereby achieving effective separation of metal and concrete waste.

[0010] Preferably, a blower is fixedly installed on the outer surface of each magnetic separator, a connecting pipe is fixedly connected to the output end of each blower, the end of each connecting pipe away from the blower is fixedly connected to the corresponding magnetic separator, and a second discharge port is opened on the side of each magnetic separator away from the corresponding blower.

[0011] By adopting the above technical solution, the waste material after magnetic separation falls by starting the blower. The blower blows air into the magnetic separation box through the connecting pipe. Under the action of the stable air field generated by the blower, due to the different densities of sand, gravel, cement dust and other components, the lighter cement dust and other impurities are blown to the second discharge port on one side, while the heavier sand and gravel particles fall directly and enter the subsequent water washing and screening stage.

[0012] Preferably, a dust collection box is fixedly connected to the outer surface of each magnetic separator, and the inner wall of each dust collection box is fixedly connected to the corresponding second discharge port.

[0013] By adopting the above technical solution, when the blower starts, lighter cement dust and other impurities are blown to the second discharge port on one side and enter the dust collection box.

[0014] Preferably, each of the magnetic separators is fixedly connected to a washing tank at its output end, a washing motor is fixedly installed on the outer surface of each washing tank, and a washing drum is fixedly connected to the output end of each washing motor.

[0015] By adopting the above technical solution, the water washing and screening equipment adopts a drum structure. The inside of the water washing drum is equipped with a water spraying device and a spiral blade. The nozzles of the water spraying device are evenly distributed on the inner wall of the water washing drum, which can spray water evenly into the drum. The pitch and rotation direction of the spiral blade are reasonably designed, which can push the sand and gravel particles to roll slowly inside the drum. When the sand and gravel particles after being screened by air enter the drum, the water spraying device starts to spray water. Under the flushing of water flow and the pushing of the spiral blade, the impurities and residual cement slurry on the surface of the sand and gravel gradually fall off.

[0016] Preferably, each of the washing tanks is provided with a water outlet pipe on its outer side, and the inner wall of each water outlet pipe is fixedly connected to the corresponding washing tank.

[0017] By adopting the above technical solution, the wastewater after cleaning is discharged through the outlet pipe at the bottom of the drum and enters the wastewater treatment system.

[0018] Preferably, the output end of each washing tank is fixedly connected to a drying tank, the output end of each drying tank is fixedly connected to a crusher, and the output end of each crusher is fixedly connected to a grinding machine.

[0019] By adopting the above technical solution, the cleaned pure sand and gravel are discharged from the discharge port at the other end of the drum and enter the drying box. After being washed, screened and dried, the pure sand and gravel particles are transported to the storage bin and used as recycled aggregate for the production of new concrete. The concrete blocks containing steel bars first enter the crusher for crushing. The crusher adopts a jaw crusher. Through the relative movement between the movable jaw plate and the fixed jaw plate, the concrete blocks are crushed into smaller particles. The crushed particles are further screened by the vibrating screen and magnetic separation equipment to further separate the steel bars and concrete fragments. After the steel bars are cleaned and sorted, they can be recycled and reused as scrap steel. Then the cement lumps are transported to the grinding mill. The grinding equipment adopts a ball mill. Through the impact and grinding action of steel balls, the cement lumps are processed into fine powder that meets the requirements.

[0020] Preferably, a control panel is fixedly installed on the outer surface of the box, a box cover is fixedly installed on the upper surface of the box, and a feed inlet is fixedly connected to the outer surface of the box cover.

[0021] By adopting the above technical solution, operators can easily set various parameters through the control panel. The human-machine interface adopts a touch screen design, which is simple and intuitive. On the interface, parameters such as grid specifications, vibrating screen mesh diameter, magnetic field strength of magnetic separator, fan power of air screening device, and water spray intensity of water washing screening device can be set. At the same time, the human-machine interface can also display the equipment's operating status and waste processing progress in real time, making it convenient for operators to monitor the entire processing process. The grid plate can be disassembled and assembled by opening the box cover, and the feed inlet facilitates the feeding of materials.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This concrete waste sorting, screening, and recycling device comprises a servo motor, transmission mechanism, vibrating motor, transmission wheel, transmission belt, connecting rod, fixed frame, first discharge port, support rod, and grating. Material is fed into the chamber, and the vibrating motor drives the chamber to vibrate and screen.

This device significantly improves automation through the use of servo and vibrating motors. Attached Figure Description

Several grid plates 4 are installed inside the housing 1, with the inner wall of each grid plate 4 connected to a corresponding support rod 5. Several first discharge ports 6 are opened on the outer surface of the housing 1. Two fixed frames 7 are provided on the outer side of the housing 1. A transmission mechanism 8 is fixedly installed on the inner wall of each fixed frame 7. A connecting rod 10 is fixedly connected to the outer surface of each transmission mechanism 8. A transmission wheel 11 is fixedly connected to the outer surface of each connecting rod 10. A transmission belt 12 is provided on the outer side of the housing 1, with the outer surface of each transmission wheel 11 connected to the transmission belt 12. A servo motor 9 is fixedly installed on the outer surface of one of the fixed frames 7, and the output end of the servo motor 9 is fixedly connected to one of the transmission mechanisms 8. A vibration motor 13 is fixedly installed on the outer surface of the housing 1.

[0027] like Figure 1 , Figure 3 , Figure 4 First, the grating plate 4 is placed in the designated position inside the box 1. Then, the corresponding grating plate 4 is fixed by inserting the support rod 5. The material to be screened is then poured into the box 1, and the vibration motor 13 is started. The box 1 drives the grating plate 4 to vibrate, and the material is layered during vibration. During this process, materials of the correct size fall from the corresponding first discharge port 6 into the transmission belt 12 below through the gaps in the grating plate 4 at different positions. At the same time, the servo motor 9 is started. The servo motor 9 drives the transmission wheel 11 to rotate through the transmission mechanism 8 and the connecting rod 10. The transmission wheel 11 drives the transmission belt 12 to rotate, so that the transmission mechanisms 8 on both sides operate synchronously. In this way, the material falling from the first discharge port 6 is transported to the designated position. Waste materials of different particle size ranges fall into different collection tanks through their respective first discharge ports 6, realizing the initial particle size classification. The setting of the servo motor 9 and the vibration motor 13 can greatly improve the automation level of the equipment.

The outer surface of each scraper 19 is slidably connected to the corresponding magnetic roller 18. The waste material after preliminary screening by the vibrating screen is conveyed to the magnetic separator 14 by the conveyor belt. At this time, the magnetic block 17 provides magnetic output to the magnetic roller 18. When the waste material containing magnetic materials such as steel bars passes near the magnetic roller 18, the steel bars are attracted to the surface of the magnetic roller 18 by the magnetic field. As the magnetic roller 18 rotates, the steel bars are carried to the other side. The scraper 19 scrapes off the attracted steel bars and they fall into the collection area of ​​the magnetic separator 14 after leaving the conveyor belt, thereby achieving effective separation of metal and concrete waste.

The end of each connecting pipe 16 away from the blower 15 is fixedly connected to the corresponding magnetic separator 14. Each magnetic separator 14 has a second discharge port 20 on the side away from the corresponding blower 15. When the waste material after magnetic separation falls, the blower 15 is activated. The blower 15 blows air into the magnetic separator 14 through the connecting pipe 16. Under the stable air field generated by the blower 15, due to the different densities of sand, gravel, cement dust and other components, the lighter cement dust and other impurities are blown to the second discharge port 20 on one side, while the heavier sand and gravel particles fall directly and enter the subsequent water washing and screening stage.

The inner wall of each dust collection box 21 is fixedly connected to the corresponding second discharge port 20. When the blower 15 is started, lighter cement dust and other impurities are blown to the second discharge port 20 on one side and enter the dust collection box 21.

[0031] like Figure 4 , Figure 5 , Figure 6Each magnetic separator 14 has a fixed connection to a washing tank 22 at its output end. Each washing tank 22 has a fixed installation of a washing motor 26 on its outer surface. Each washing motor 26 has a fixed connection to a washing drum 27 at its output end. The washing and screening equipment adopts a drum structure. The washing drum 27 is equipped with a water spraying device and spiral blades. The nozzles of the water spraying device are evenly distributed on the inner wall of the washing drum 27, which can spray water evenly into the drum. The pitch and rotation direction of the spiral blades are reasonably designed to push the sand and gravel particles to roll slowly inside the drum. When the sand and gravel particles after being screened by the wind enter the drum, the water spraying device starts to spray water. Under the flushing of the water flow and the pushing of the spiral blades, the impurities and residual cement slurry on the surface of the sand and gravel gradually fall off.

The inner wall of each water outlet pipe 28 is fixedly connected to the corresponding washing tank 22. The wastewater after washing is discharged through the water outlet pipe 28 at the bottom of the drum and enters the wastewater treatment system.

The cleaned pure sand and gravel are discharged from the discharge port at the other end of the drum and enter the drying tank 23. After washing, screening and drying, the pure sand and gravel particles are transported to the storage bin and used as recycled aggregate for the production of new concrete. The concrete blocks containing steel bars first enter the crusher 24 for crushing. The crusher 24 is a jaw crusher. Through the relative movement between the movable jaw plate and the fixed jaw plate, the concrete blocks are crushed into smaller particles. The crushed particles are further screened by a vibrating screen and a magnetic separator to further separate the steel bars and concrete fragments. After cleaning and sorting, the steel bars can be recycled and reused as scrap steel. Then, the cement lumps are transported to the grinding mill 25. The grinding equipment is a ball mill. Through the impact and grinding action of steel balls, the cement lumps are processed into fine powder that meets the requirements.

On the interface, parameters such as the grid specifications, the mesh size of the vibrating screen, the magnetic field strength of the magnetic separator, the power of the blower 15 of the wind-powered screening device, and the water spray intensity of the water washing screening device can be set. At the same time, the human-machine interface can also display the operating status of the equipment and the progress of waste treatment in real time, which makes it convenient for operators to monitor the entire processing process. The grid plate 4 can be disassembled and assembled by opening the cover 2, and the feed inlet 3 facilitates the feeding of materials.

[0035] The implementation principle of this application embodiment is as follows: First, the material is fed into the feed inlet 3, and then the vibration motor 13 is started to drive the box 1 and the grid plate 4 to vibrate. After the concrete waste enters the vibrating screen, under the high-frequency vibration generated by the vibration motor 13, waste of different particle sizes jumps and rolls on the grid plates 4 of different specifications. Waste of different particle size ranges falls into different transmission mechanisms 8 through their respective first discharge ports 6, realizing preliminary particle size classification. Then, the magnetic block 17 is started and drives the magnetic drum 18 to run. When waste containing magnetic materials such as steel bars passes near the magnetic drum 18, the steel bars are attracted to the surface of the magnetic drum 18 by the magnetic field. As the magnetic drum 18 rotates... The reinforcing bars are carried to the other side and enter the collection area under the action of scraper 19, thereby achieving effective separation of metal and concrete waste. During this process, the blower 15 is started to blow lighter cement dust and other impurities through the connecting pipe 16 to the second discharge port 20 and enter the dust collection box 21. Heavier sand and gravel particles enter the washing box 22.
