Description

Technical Field

[0001] This utility model relates to the field of recycled aggregates, and in particular to a recycled aggregate pre-wetting machine. Background Technology

[0002] The preparation of recycled aggregates from construction waste is currently a key focus of research on the recycling of construction waste. With the increasing awareness of sustainable development and the development of science and technology, more and more solid wastes can be recycled, most of which become recycled aggregates. In order to reduce the negative impact of the high water absorption characteristics of recycled aggregates on the performance of concrete, it is necessary to pre-wet the recycled aggregates using a recycled aggregate pre-wetting machine before concrete preparation.

[0003] Currently, some recycled aggregate pre-wetting machines still have certain shortcomings in use: Some drum-type recycled aggregate pre-wetting machines on the market inject a certain amount of water into the drum, and then use an external motor to drive the drum to rotate slowly, thereby cleaning the dust on the surface of the recycled aggregate and increasing its moisture content. However, after pre-wetting, it is difficult to completely pour out the aggregate in the drum. Some aggregate and smaller particles are prone to adhering to the inner wall of the drum due to the surface tension and cohesive force of water. After the machine is used, manual handling by workers is still required. Secondly, the current structure of recycled aggregate pre-wetting machines is not good at effectively settling and reusing the wastewater generated from washing aggregates, thus failing to save water resources.

[0004] Therefore, it is necessary to provide a new recycled aggregate pre-wetting machine to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a recycled aggregate pre-wetting machine that can effectively settle and utilize wastewater, while facilitating the cleaning of aggregates and other materials adhering to the inner wall of the drum.

[0006] To solve the above-mentioned technical problems, this utility model provides a recycled aggregate pre-wetting machine comprising: a base, a cylinder, a cleaning component, and a sedimentation component. The cylinder is located on the upper side of the base, and a roller is rotatably connected inside the cylinder. A rotating sleeve is fixedly connected to one end of the roller. The rotating sleeve is rotatably connected to the cylinder, and the end of the rotating sleeve extends to the outside of the cylinder. The cleaning component includes a movable rod located inside the rotating sleeve. A scraper is fixedly connected to the end of the movable rod inside the roller. A telescopic cylinder is fixedly connected to the top of the cylinder. The output end of the telescopic cylinder is fixedly connected to the end of the movable rod through a connecting plate. A drive motor is fixedly connected to one side wall surface of the cylinder. A transmission component is connected between the drive motor and the rotating sleeve.

[0007] The sedimentation assembly includes a sedimentation tank located on one side of the base. Two partitions arranged in a front-to-back configuration are fixedly connected inside the sedimentation tank. A water inlet trough is provided at the top of each partition. The sedimentation tank is divided into a first water storage tank, a second water storage tank, and a third water storage tank by the two partitions. A second pump body is connected to the bottom of the cylinder via a pipe. The bottom of the second pump body is connected to the first water storage tank via a flexible hose. A rangefinder is fixedly connected to one side wall of the sedimentation tank via a support frame. The rangefinder is located above the third water storage tank.

[0008] As a further embodiment of this utility model, the transmission assembly includes a large pulley and a small pulley. The large pulley is fixedly connected to the outer surface of the rotating sleeve, and the small pulley is fixedly connected to the output end of the drive motor. The large pulley and the small pulley are connected by a belt.

[0009] With the above technical solution, the user starts the drive motor to drive the small pulley to rotate, which can transmit kinetic energy through the belt to the large pulley on one side and the rotating sleeve inside the large pulley. The rotating sleeve will drive the drum inside the cylinder to rotate, thereby causing the recycled aggregate inside the drum to move, achieving the effect of cleaning and soaking.

[0010] As a further embodiment of this utility model, cantilever arms are fixedly connected to both the left and right sides of the top surface of the cylinder located on one side of the telescopic cylinder. A sealing cover is hinged to the end of the cylinder away from the rotating sleeve, and a second electric telescopic rod is hinged between the sealing cover and the end of the cantilever arm.

[0011] With the above technical solution, after the user completes the pre-wetting task, the second electric telescopic rod can be activated to open the sealing cover and the first electric telescopic rod can be activated to lower the head of the cylinder, thereby allowing the recycled aggregate inside the drum to be discharged. To prevent some aggregate and smaller particles from adhering to the inner wall of the drum due to water tension and cohesion, the user can activate the telescopic cylinder to move the movable rod to the side of the sealing cover, so that the scraper at the end of the movable rod can clean out all the recycled aggregate inside the drum. This structural design does not require manual operation by workers, is more efficient, and frees up workers' hands, making it a user-friendly design.

[0012] As a further embodiment of this utility model, a support leg is fixedly connected to the top edge of the base, the support leg is hinged to the bottom of the cylinder, and a first electric telescopic rod is hinged between the top surface of the base and the bottom surface of the cylinder on the side of the support leg.

[0013] With the above technical solution, when it is necessary to pour out the recycled aggregate inside the drum, the user can activate the first electric telescopic rod to move the head of the drum downward, so that the recycled aggregate inside the drum can fall out under the action of gravity.

[0014] As a further embodiment of this utility model, a communicating vessel is provided on one side of the third water storage tank. The bottom of the communicating vessel is connected to a water inlet pipe. Two water inlet pipes are provided on the surface of the communicating vessel, and the end of the water inlet pipe on one side is connected to the third water storage tank.

[0015] Through the above technical solution, the device is equipped with a sedimentation tank with multiple water storage tanks. When the sewage in the cylinder is discharged into the first water storage tank, it will settle there. When the water level reaches the height of the inlet tank, it will flow into the second water storage tank and continue to settle for the second time. The water flowing into the third water storage tank has fewer impurities and can be used to clean the recycled aggregate. At this time, the user can use the second pump to draw water from the third water storage tank into the cylinder for use. The structure also has a rangefinder added to the top of the third water storage tank, which can monitor in real time whether the liquid storage in the third water storage tank has reached the amount required for cylinder pre-wetting, avoiding the second pump from sucking dry. If the water level inside is low, the user can close the solenoid valve on this side of the inlet pipe and open the solenoid valve on the other side of the inlet pipe on the connector. This inlet pipe should be connected to an external water source. In this way, the structure can effectively settle and fully utilize the sewage generated from the pre-wetting of recycled aggregate. The structural design is energy-saving and environmentally friendly.

[0016] As a further embodiment of this utility model, a water injection pipe is connected between the top of the cylinder and the communicating vessel, a first pump body is installed on the surface of the water injection pipe, and a solenoid valve is installed on the surface of both water inlet pipes.

[0017] Through the above technical solution, the water inlet pipe on one side is connected to the third water storage tank to extract the water that has been effectively settled inside for reuse. When the water volume inside is insufficient, the water inlet pipe on the other side can be used to extract external water sources for use.

[0018] As a further embodiment of this utility model, a control module is fixedly connected to one side of the surface of the base, and the first pump body, the second pump body, the telescopic cylinder, the first electric telescopic rod, the second electric telescopic rod, the solenoid valve, and the drive motor are all electrically connected to the control module.

[0019] With the above technical solution, all electrical appliances in this structure can be started and stopped using the control module, making operation convenient and simple.

The water flowing into the third water storage tank has fewer impurities and can be used to clean the recycled aggregate. At this time, the user can use the second pump to draw water from the third water storage tank into the cylinder for use. The structure also has a rangefinder added to the top of the third water storage tank, which can monitor in real time whether the liquid storage in the third water storage tank has reached the amount required for cylinder pre-wetting, avoiding the second pump from sucking dry.

Figure 1 ; Figure 2 This is a schematic diagram of the overall structure of a recycled aggregate pre-wetting machine according to the present invention. Figure 2 ; Figure 3 This is a partial structural schematic diagram of a recycled aggregate pre-wetting machine according to the present invention;

[0031] Figure 4 This is a partially exploded view of a recycled aggregate pre-wetting machine according to the present invention. The recycled aggregate pre-wetting machine includes:

[0032] The system comprises a base 1, a cylinder 2, a cleaning assembly 4, and a sedimentation assembly 9. The cylinder 2 is located on the upper side of the base 1. A roller 20 is rotatably connected inside the cylinder 2. A rotating sleeve 25 is fixedly connected to one end of the roller 20. The rotating sleeve 25 is rotatably connected to the cylinder 2, and the end of the rotating sleeve 25 extends to the outside of the cylinder 2. The cleaning assembly 4 includes a movable rod 13, which is located inside the rotating sleeve 25. A scraper 24 is fixedly connected to the end of the movable rod 13 inside the roller 20. A telescopic cylinder 10 is fixedly connected to the top of the cylinder 2. The output end of the telescopic cylinder 10 is fixedly connected to the end of the movable rod 13 through a connecting plate. A drive motor 26 is fixedly connected to one side wall surface of the cylinder 2. A transmission assembly 3 is connected between the drive motor 26 and the rotating sleeve 25.

[0033] The sedimentation assembly 9 includes a sedimentation tank 19, which is located on one side of the base 1. The sedimentation tank 19 has two partitions 21 that are arranged in a front-to-back pattern. The top of the partitions 21 has a water inlet trough 22. The interior of the sedimentation tank 19 is divided into a first water storage tank, a second water storage tank, and a third water storage tank by the two partitions 21. The bottom of the cylinder 2 is connected to a second pump body 23 through a pipe. The bottom of the second pump body 23 is connected to the first water storage tank through a hose. A rangefinder 18 is fixedly connected to one side wall of the sedimentation tank 19 through a support frame. The rangefinder 18 is located on the upper side of the third water storage tank.

[0034] like Figure 1-4As shown, the transmission assembly 3 includes a large pulley 12 and a small pulley 11. The large pulley 12 is fixedly connected to the outer surface of the rotating sleeve 25, and the small pulley 11 is fixedly connected to the output end of the drive motor 26. The large pulley 12 and the small pulley 11 are connected by a belt.

[0035] When the user starts the drive motor 26, it drives the small pulley 11 to rotate, which can transmit kinetic energy through the belt to the large pulley 12 on one side and the rotating sleeve 25 inside the large pulley 12. The rotating sleeve 25 will drive the drum 20 inside the cylinder 2 to rotate, thereby causing the recycled aggregate inside the drum 20 to move, achieving the effect of cleaning and soaking.

[0036] like Figure 1-4 As shown, cantilever arms are fixedly connected to both sides of the top surface of the cylinder 2 located on one side of the telescopic cylinder 10. A sealing cover 8 is hinged to the end of the cylinder 2 away from the rotating sleeve 25. A second electric telescopic rod 7 is hinged between the sealing cover 8 and the end of the cantilever arm.

[0037] After the user completes the pre-wetting task, the second electric telescopic rod 7 can be activated to open the sealing cover 8 and the first electric telescopic rod 6 can be activated to lower the head of the cylinder 2, thereby allowing the recycled aggregate inside the drum 20 to be discharged. To prevent some aggregate and smaller particles from adhering to the inner wall of the drum 20 due to water tension and cohesion, the user can activate the telescopic cylinder 10 to move the movable rod 13 to the side of the sealing cover 8, thereby allowing the scraper 24 at the end of the movable rod 13 to clean out all the recycled aggregate inside the drum 20. This structural design eliminates the need for manual operation by workers, improves efficiency, and frees up workers' hands, demonstrating a user-friendly design.

[0038] like Figure 1-4 As shown, a support leg is fixedly connected to the top edge of the base 1. The support leg is hinged to the bottom of the cylinder 2. A first electric telescopic rod 6 is hinged between the top surface of the base 1 and the bottom surface of the cylinder 2 on the side of the support leg.

[0039] When it is necessary to pour out the recycled aggregate inside the drum 20, the user can activate the first electric telescopic rod 6 to move the head of the drum 2 downward, so that the recycled aggregate inside the drum 20 can fall out under the action of gravity.

[0040] like Figure 1-4 As shown, a communicating vessel 16 is provided on one side of the third water storage tank. A water inlet pipe 17 is connected to the bottom of the communicating vessel 16. Two water inlet pipes 17 are provided on the surface of the communicating vessel 16. The end of one side of the water inlet pipe 17 is connected to the third water storage tank.

[0041] The device is equipped with a sedimentation tank 19 containing multiple water storage tanks. When the wastewater in the cylinder 2 is discharged into the first water storage tank, it will settle there. When the water level reaches the height of the inlet tank 22, it will flow into the second water storage tank and continue to settle there for the second time. The water flowing into the third water storage tank has fewer impurities and can be used to clean the recycled aggregate. At this time, the user can use the second pump 23 to draw water from the third water storage tank into the cylinder 2 for use. The structure also has a rangefinder 18 added to the top of the third water storage tank, which can monitor in real time whether the liquid storage in the third water storage tank has reached the amount required for pre-wetting the cylinder 2, thus preventing the second pump 23 from sucking dry. If the water level is low, the user can close the solenoid valve on the inlet pipe 17 on this side and open the solenoid valve on the other side of the inlet pipe 17 on the connector 16. The inlet pipe 17 should be connected to an external water source. In this way, the structure can effectively settle and fully utilize the wastewater generated from the pre-wetting of recycled aggregate. The structure design is energy-saving and environmentally friendly.

[0042] like Figure 1-4 As shown, a water injection pipe 14 is connected between the top of the cylinder 2 and the communicating vessel 16. A first pump body 15 is installed on the surface of the water injection pipe 14, and solenoid valves are installed on the surfaces of the two water inlet pipes 17.

[0043] One side of the water inlet pipe 17 is connected to the third water storage tank to extract water that has been effectively settled inside for reuse. When the water inside is insufficient, external water sources can be extracted using the other side of the water inlet pipe 17.

[0044] like Figure 1-4 As shown, a control module 5 is fixedly connected to one side of the surface of the base 1. The first pump body 15, the second pump body 23, the telescopic cylinder 10, the first electric telescopic rod 6, the second electric telescopic rod 7, the solenoid valve, and the drive motor 26 are all electrically connected to the control module 5.

[0045] All electrical appliances in this structure can be started and stopped using the control module 5, making operation convenient and simple.

[0046] The working principle of the recycled aggregate pre-wetting machine provided by this utility model is as follows:

[0047] First step: The device is equipped with a sedimentation tank 19 with multiple water storage tanks. When the sewage in the cylinder 2 is discharged into the first water storage tank, it will settle in it. When the water level reaches the height of the inlet tank 22, it will flow into the second water storage tank and continue to settle for the second time. The water flowing into the third water storage tank has fewer impurities and can be used to clean the recycled aggregate. At this time, the user can use the second pump 23 to draw water from the third water storage tank into the cylinder 2 for use. The structure also has a rangefinder 18 added to the top of the third water storage tank, which can monitor in real time whether the liquid storage in the third water storage tank has reached the amount required for pre-wetting the cylinder 2, and avoid the second pump 23 from being empty. If the water level inside is low, the user can close the solenoid valve on the inlet pipe 17 on this side and open the solenoid valve on the other side of the inlet pipe 17 on the connector 16. The inlet pipe 17 should be connected to an external water source. In this way, the structure can effectively settle and fully utilize the sewage generated from the pre-wetting of recycled aggregate. The structure design is energy-saving and environmentally friendly.

[0048] The second step: After the user completes the pre-wetting task, the second electric telescopic rod 7 can be activated to open the sealing cover 8 and the first electric telescopic rod 6 can be activated to lower the head of the cylinder 2, so that the recycled aggregate inside the drum 20 can be discharged. In order to prevent some aggregate and smaller particles from adhering to the inner wall of the drum 20 due to water tension and cohesion, the user can activate the telescopic cylinder 10 to move the movable rod 13 to the side of the sealing cover 8, so that the scraper 24 at the end of the movable rod 13 can clean out all the recycled aggregate inside the drum 20. This structural design does not require manual operation by workers, which is more efficient and frees up workers' hands, making it a user-friendly design.
