Description

Technical Field

[0001] This invention relates to the field of recycled sand washing machine technology, specifically a recycled sand washing machine for construction waste. Background Technology

[0002] The dumping of construction waste not only occupies a large amount of land as a disposal site, but also wastes manpower and resources in the maintenance of the disposal site, and leads to secondary pollution of the environment. In addition, the sand and gravel aggregates used in concrete, which are the largest component of the construction industry, are not inexhaustible and are in short supply in most areas. Therefore, it is necessary to recycle and reuse construction waste, which can not only provide sand and gravel for related industries, but also help reduce the land occupation and environmental pollution caused by the dumping of urban waste, and ensure the long-term sustainable development of the construction industry.

[0003] Existing construction waste recycled sand washing machines typically require placing the waste sand inside the machine and continuously rinsing its surface with nozzles. However, the sand inside the machine is usually piled up, and direct rinsing can result in some sand at the bottom not being thoroughly cleaned. According to a construction waste recycled sand washing device described in patent number CN 213591227 U, a motor-driven vibration control system is used to vibrate a filter screen. The sand is placed on the filter screen and vibrated while being rinsed. However, this device, relying solely on vibration, struggles to thoroughly clean the sand piled on the filter screen. Existing construction waste recycled sand washing machines can only clean the sand; after cleaning, it still needs to be dried in a drying device before being collected. This results in poor cleaning efficiency, with the cleaned sand having a high moisture content and being heavy. The transfer to the drying process incurs significant labor costs and reduces cleaning efficiency. Furthermore, existing construction waste recycled sand washing machines lack automatic loading, unloading, and collection devices, leading to low cleaning efficiency.

[0004] Therefore, we propose a construction waste recycled sand washing machine. Summary of the Invention

Through the transmission connection between the drive pulley 30 and the first driven pulley 28, the transmission rod 19 is rotated, so that the sand-dispelling plate 20 continuously moves the waste sand and gravel inside the cleaning cylinder 12, achieving the effect of rinsing and stirring the sand and gravel at the same time, thus achieving efficient cleaning of waste sand and gravel.

[0035] The water recycling mechanism 7 includes a water tank 37, a filter screen 38, and a water outlet 40. The treatment tank 1 is located on one side of the vertical plane of the first screw conveyor 8 and is connected to the water tank 37. The side wall of the treatment tank 1 is provided with a water outlet 40, one end of which is located at the lower end of the water storage chamber 11, and the other end of which is located above the water tank 37. The water tank 37 is provided with a filter screen 38.

The ends of the lifting plates 39 are provided with lifting rings 41. The water used to wash sand and gravel enters the water storage chamber 11 through the drain hole 18, and then enters the water tank 37 through the water outlet 40. It is filtered by the filter screen 38 in the water tank 37 to remove impurities, so that the recycled water is collected in the water tank 37, avoiding the waste of water resources.

[0036] The outer side of the cleaning cylinder 12 is provided with drainage holes 18 at equal intervals, and the diameter of the drainage holes 18 is smaller than the particle size of the recycled sand, while the diameter of the connecting hole 21 is larger than the particle size of the recycled sand.

After cleaning, the electric control valve 23 on the discharge cylinder 22 is opened, so that the cleaned sand and gravel inside the cleaning cylinder 12 are placed inside the drying chamber 24. At this time, the heating wire inside the drying plate 26 is activated. When the rotating motor 42 is working, the rotating rod 25 is rotated under the transmission connection of the driving pulley 30 and the second driven pulley 29. The drying plate 26 continuously moves the sand and gravel inside the drying chamber 24, so that the sand and gravel are fully in contact with the drying plate 26, thereby achieving high-efficiency drying of the sand and gravel and avoiding subsequent cumbersome operation steps.

[0038] Both the ends of the transmission rod 19 and the rotating rod 25 pass through the processing box 1. A first driven pulley 28 is fixedly installed at one end of the transmission rod 19 outside the processing box 1, and a second driven pulley 29 is fixedly installed at one end of the rotating rod 25 outside the processing box 1. A driving pulley 30 is rotatably arranged in the middle of the side wall of the processing box 1 between the first driven pulley 28 and the second driven pulley 29.

Through the transmission connection between the driving pulley 30 and the first driven pulley 28 and the second driven pulley 29, the rotating rod 25 and the transmission rod 19 can be rotated. Thus, the rotation of the sand-removing plate 20 inside the washing cylinder 12 and the drying plate 26 inside the drying chamber 24 can be controlled at one time, realizing a rapid cleaning and drying process and improving the cleaning efficiency of waste sand and gravel.

[0040] The clean sand collection mechanism 6 includes a support platform 32, a second screw conveyor 33, a third screw conveyor 34, and a discharge port 35.

[0042] Both the discharge cylinder 31 and the discharge cylinder 22 are equipped with electrically controlled valves 23 on their outer sides, which facilitates the control of the opening and closing of the discharge cylinder 31 and the discharge cylinder 22.

[0043] Specifically, when using this invention, the waste sand and gravel to be cleaned is placed in the feeding hopper 9. The first spiral feeder 8 is controlled by the power control system of the device to place the waste sand and gravel into the installation hopper 13, and then enters the cleaning cylinder 12 through the installation hopper 13. At this time, the water pump 14 is controlled to pump external water into the outlet pipe 15 and spray it into the cleaning cylinder 12 through the flushing nozzle 16. At the same time, the motor 42 is rotated to make the drive pulley 30 rotate. Through the transmission connection between the drive pulley 30 and the first driven pulley 28, the transmission rod 19 is rotated, so that the sand-dispensing plate 20 continuously dispenses the waste sand and gravel inside the cleaning cylinder 12, achieving the effect of washing and stirring the sand and gravel at the same time, achieving efficient cleaning of the waste sand and gravel. The water used to clean the sand and gravel enters the water storage chamber 11 through the drain hole 18, and then enters the water tank 37 through the outlet 40, and is filtered by the filter screen 38 in the water tank 37 to remove impurities. The recovered water is collected in the water tank 37. After cleaning, the electric control valve 23 on the discharge cylinder 22 is opened, allowing the cleaned sand and gravel inside the cleaning cylinder 12 to be placed inside the drying chamber 24. At this time, the heating wire inside the drying plate 26 is activated. When the rotating motor 42 is working, the rotating rod 25 rotates under the transmission connection of the driving pulley 30 and the second driven pulley 29. The drying plate 26 continuously moves the sand and gravel inside the drying chamber 24, allowing the sand and gravel to fully contact the drying plate 26, thereby achieving high-efficiency drying of the sand and gravel and avoiding subsequent cumbersome operation steps. After drying, the electric control valve 23 on the discharge cylinder 31 is opened, allowing the dried sand and gravel to be placed inside the second screw conveyor 33. By controlling the operation of the second screw conveyor 33, the sand and gravel can be placed inside the third screw conveyor 34. Then, the operation of the third screw conveyor 34 allows the dried sand and gravel to enter the clean sand collection box 2 for collection.
