Description

Technical Field

[0001] The utility model relates to the technical field of concrete waste separation devices, in particular to a concrete waste separation device. Background Art

[0002] Concrete, also referred to as tong or shi shi, is a general term for composite materials formed by proportioning gel materials, aggregates and water in an appropriate ratio and hardening over a certain period of time. It is the most widely used artificial civil construction material in the world. With high hardness, wide raw material sources and low cost, concrete is widely used in structures such as houses, highways, military projects, and nuclear power plants. When concrete is used, stones need to be added inside the concrete, which tends to cause excessive mixing of concrete and result in unused surplus when used, thus requiring a concrete waste treatment device; When handling existing residual mixed concrete waste, water flushing is used in combination with a screen to separate stones and sand, but the subsequent separation of sand and sewage mixture has low efficiency. Due to uneven particle size of sand, the sedimentation method takes a long time. When a filter screen is used for separation, fine sand particles and impurities can easily block the filter screen pores. To maintain the separation effect, it is necessary to frequently shut down for cleaning or replace the filter screen, which not only increases labor costs, but also causes interruption of the treatment process. In addition, filter screen blockage can also cause the risk of sewage overflow. Therefore, we propose a concrete waste separation device to solve the above-mentioned problems. Utility Model Content

[0003] The purpose of the utility model is to provide a concrete waste separation device to solve the problem that the filter screen needs frequent cleaning when separating sand and sewage during the use of the existing concrete waste separation device proposed in the above background art.

[0014] Please see Figure 1-4 This utility model provides a technical solution: a concrete waste separation device, including a base 1, a separation chamber 2, a belt conveyor 3, and a feeding trough 4. Damping springs 5 ​​are provided at the four corners of the top of the base 1. One end of each of the four damping springs 5 ​​is connected to the four corners of the separation chamber 2. Vibration motors 6 are provided on both sides of the bottom of the separation chamber 2. A screening screen 7 is detachably provided inside the separation chamber 2. A guide plate 8 is detachably provided on one side of the screening screen 7. A conveying plate 9 is detachably provided below the screening screen 7 inside the separation chamber 2. Multiple sets of water pipes 10 are detachably provided on the side wall of the base 1. Multiple sets of nozzles 11 are provided on each of the multiple sets of water pipes 10. The multiple sets of water pipes 10 are all connected to an external water supply system. A manual valve 21 is provided on each of the multiple sets of water pipes 10. During the process, the mixed concrete residue waste is dumped onto the screen plate 7 inside the separation chamber 2 by a mixer truck. At the same time, the vibration motors 6 on both sides of the bottom, together with the damping springs 5, make the separation chamber 2 vibrate. Simultaneously, the manual valve 21 on the water supply pipe 10 can be opened as needed, so that the flushing water source in the water supply system enters the nozzle 11 and sprays out to flush the waste. With the help of the vibrating screen plate 7, large stones in the waste are screened out. The wastewater generated during the sand flushing process enters the conveyor plate 9 below. At this time, the separated stones are conveyed to the belt conveyor 3 along with the guide plate 8. The belt conveyor 3 transports the screened and cleaned stones to the outside. A belt conveyor 3 and a feeding trough 4 are located on the right side of the separation chamber 2. The belt conveyor 3 and the feeding trough 4 are connected by a connecting rod 12. The two ends of the connecting rod 12 are detachably connected to the bottom of the belt conveyor 3 and the top of the feeding trough 4, respectively. A feeding mesh belt 13 is installed inside the feeding trough 4. The feeding trough 4 is connected to the feeding mesh belt 13 through a drive assembly 14. The drive assembly 14 includes a drive roller 141 and a sprocket 142. Adaptive drive rollers 141 are provided on both sides inside the feeding mesh belt 13. Both sets of drive rollers 141 are rotatably connected to the inside of the feeding trough 4. One end of a single drive roller 141 rotates through the feeding trough. The feeding trough 4 has a drive roller 141 with a sprocket 142 mounted on one end, and a brush roller 15 with one end rotating through it. The brush roller 15 has a sprocket 142 mounted on one end, and the sprocket 142 on the brush roller 15 and the sprocket 142 on the drive roller 141 are connected by a chain 17. The brush roller 15 is rotatably mounted inside the feeding trough 4. A discharge guide plate 16 is provided at one end of the feeding trough 4. Wastewater collection hoppers 18 are provided on both sides of the bottom of the feeding trough 4. Drain pipes 19 are provided at the bottom of both sets of wastewater collection hoppers 18. A baffle 20 is provided on the right side of the top of the feeding trough 4. A motor for driving a single drive roller 141 is provided on the side wall of the feeding trough 4. The wastewater and sand generated at this time are transported through the conveyor plate 9 to the upper part of the feeding mesh belt 13 inside the feeding trough 4. At this time, the drive roller 141 is driven by the motor to rotate. The drive roller 141 drives the feeding mesh belt 13 to move. At the same time, the feeding mesh belt 13 separates the sand and wastewater, so that the wastewater enters the wastewater collection hopper 18 below for collection. Meanwhile, the feeding mesh belt 13 transports the sand to one side and dumps the sand onto the upper part of the discharge guide plate 16 below. At the same time, the drive roller 141 rotates and the sprocket 142 at one end rotates synchronously. At this time, the sprocket 142 drives the chain 17 to rotate. The chain 17 drives the sprocket 142 at one end of the brush roller 15 to rotate simultaneously. At this time, the brush roller 15 rotates and cleans the sand remaining on the surface of the screening mesh belt.

[0015] Working Principle: When using the concrete waste separation device, the mixed concrete residue waste is poured from the mixer truck onto the screen plate 7 inside the separation chamber 2. Simultaneously, the vibrating motors 6 on both sides of the bottom, in conjunction with the damping springs 5, cause the separation chamber 2 to vibrate. At the same time, the manual valve 21 on the water supply pipe 10 can be opened as needed, allowing the flushing water from the water supply system to enter the nozzles 11 and spray out to wash the waste. The vibrating screen plate 7 then separates the large stones from the waste. Wastewater generated during the sand washing process enters the conveyor plate 9 below. The separated stones, along with the guide plate 8, are then conveyed to the belt conveyor 3. The belt conveyor 3 transports the screened and washed stones to the outside. The wastewater and sand generated during this process are conveyed through the conveyor plate 9 to the feeding trough 4. Above the mesh belt 13, the drive roller 141 is driven by the motor to rotate. The drive roller 141 moves the feeding mesh belt 13, which separates the sand and sewage. The sewage enters the wastewater collection hopper 18 below for collection. At the same time, the feeding mesh belt 13 transports the sand to one side and dumps it onto the discharge guide plate 16 below. Simultaneously, the drive roller 141 rotates, and the sprocket 142 at one end rotates synchronously. The sprocket 142 drives the chain 17 to rotate, and the chain 17 drives the sprocket 142 at one end of the brush roller 15 to rotate. The brush roller 15 then cleans the sand remaining on the surface of the screening mesh belt, thus completing a series of operations.
