[0002] Concrete is a mixture made by mixing cementitious materials, granular aggregates, water, and chemical admixtures and mineral additives in appropriate proportions. It is widely used in civil engineering. With the booming development of the construction industry, the large-scale use of concrete has led to a huge consumption of sand and gravel resources. Therefore, recycling sand and gravel from waste concrete has become a key way to alleviate resource pressure and reduce production costs.

[0003] Currently, existing concrete aggregate recycling and separation equipment faces numerous problems in practical applications. Some equipment suffers from low separation efficiency, failing to quickly and accurately separate aggregates from waste concrete, thus affecting recycling efficiency and quality. Furthermore, some equipment, lacking effective heat dissipation measures, generates excessive heat during prolonged operation, leading to component performance degradation and shortened equipment lifespan. Therefore, developing a highly efficient, stable concrete aggregate recycling and separation device with excellent screening capabilities is urgently needed. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a self-contained rotary component for concrete sand and gravel recycling and separation. It can quickly and accurately separate sand and gravel from waste concrete, ensuring recycling efficiency and quality. It can also uniformly and continuously cool the shell, effectively reducing the heat generated during equipment operation and improving the stability and reliability of equipment operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 A self-contained rotary component for concrete aggregate recycling and separation includes a housing 1, a rotary feeding component 2 inside the housing 1, the rotary feeding component 2 including a rotating rod, and spiral guide plates evenly distributed on the outer wall of the rotating rod, the spiral guide plates having the same center as the rotating rod. The rotary feeding component 2 is driven to rotate by a drive motor 3, the drive motor 3 being connected to a gearbox to adjust the rotation speed of the rotary feeding component 2. Through the rotary motion of the rotary feeding component 2 and the guidance of the spiral guide plates on the inner wall, the concrete aggregate mixture moves fully within the housing 1, driving the material upward.

[0025] A feed inlet 4 is provided through the upper side of one end of the shell 1, through which concrete aggregate can be fed into the shell 1. A discharge outlet 5 is provided through the bottom of the other end of the shell 1, through which the separated concrete aggregate can be discharged. The side of the shell 1 near the feed inlet 4 is the centrifugal discharge end, which is provided with a guide cover 6. The bottom of the guide cover 6 is provided with a drop outlet 7. During the rotation of the rotary feeder 2, under the action of centrifugal force, the mixture with smaller particles and better flowability can be thrown into the guide cover 6 and discharged through the drop outlet 7.

[0026] The shell 1 has a double-walled structure with a hollow interlayer 8 between the two layers. During the long-term high-speed operation of the rotary feeder 2, the heat generated by friction is carried away by the circulation of coolant, which can prevent the shell 1 from deforming due to excessive temperature and ensure the stability of equipment operation. At the same time, the double-walled structure enhances the overall strength and rigidity of the shell 1, enabling it to withstand greater centrifugal force and material impact force, and extending the service life of the equipment. Multiple annular baffles 9 are fixedly connected at equal intervals in the hollow interlayer 8. Overflow ports 10 are opened through the annular baffles 9. The overflow ports 10 on two adjacent annular baffles 9 are located on the upper and lower sides, respectively, so that the coolant can pass through the overflow port 10 on the upper side of one annular baffle 9 and then through the overflow port 10 on the lower side of the next annular baffle 9. This cycle increases the residence time of the coolant in the hollow interlayer 8, which is conducive to sufficient heat dissipation. In addition, the annular baffles 9 can support the inner lining and outer shell of the shell 1, further ensuring the overall strength and rigidity of the shell 1.

[0027] A cooling assembly is provided at the bottom of the shell 1 to introduce coolant into the hollow interlayer 8. The cooling assembly includes a cooling tank 11 located at the bottom of the shell 1. The cooling tank 11 is made of metal materials such as copper and aluminum and has good thermal conductivity, which can dissipate the heat of the coolant flowing back into the cooling tank 11. A water inlet pump 14 connected to the hollow interlayer 8 is installed at one bottom end of the shell 1. The water inlet pump 14 is connected to the cooling tank 11 through a water inlet pipe 15. A water pump 12 connected to the hollow interlayer 8 is installed at the other bottom end of the shell 1. The water pump 12 is connected to the cooling tank 11 through a drain pipe 13. The water inlet pump 14 can draw coolant from the cooling tank 11 through the water inlet pipe 15 and deliver it to the hollow interlayer 8. The water pump 12 can draw coolant from the hollow interlayer 8 through the drain pipe 13 and deliver it back to the cooling tank 11 for circulation.

[0028] Below the housing 1 is a screening assembly opposite to the discharge port 5. The screening assembly includes a base 16, with multiple telescopic buffer members fixedly connected in a rectangular array at the upper end of the base 16. The upper ends of the multiple telescopic buffer members are fixedly connected to a screening plate 19. The inner bottom of the screening plate 19 is inclined to facilitate the sliding of concrete and aggregate along the screening plate 19. A U-shaped enclosure is provided on the outer side of the screening plate 19 to block the concrete and aggregate on the screening plate 19. The telescopic buffer members include a sleeve 17 fixedly connected to the upper end of the base 16. The sleeve 17 slides inside the sleeve. A support plate 18 is dynamically connected to the screen plate 19 and fixedly connected to the bottom of the screen plate 19. Multiple springs are connected between the support plate 18 and the inner bottom of the sleeve 17. The support plate 18 slides in the sleeve 17 and cooperates with the springs, which can buffer the screen plate 19 and ensure that the screen plate 19 can vibrate stably. A screen mesh 20 is installed through the middle of the screen plate 19. A vibration motor 21 is installed at the bottom of the screen plate 19. The vibration motor 21 can drive the screen plate 19 to shake, so that the screen mesh 20 can screen the small particles of concrete sand and gravel again.

[0029] The functional principle of this utility model can be explained through the following operation methods:

[0030] In this utility model, the self-contained rotary feeder for concrete sand and gravel recycling and separation is used to add concrete sand and gravel raw materials into the shell 1 through the feed port 4. The drive motor 3 drives the rotary feeder 2 to rotate. During the rotation, the rotary feeder 2 can throw the mixture with smaller particles and better flowability into the guide cover 6 and discharge it through the discharge port 7 under the action of centrifugal force. Through the rotary motion of the rotary feeder 2 and the guidance of the spiral guide plate on the inner wall, the concrete sand and gravel mixture moves fully in the shell 1, which drives the larger particles and less flowable materials to move upward and discharge them through the discharge port 5 and fall onto the screening plate 19. The vibrating motor 21 drives the screening plate 19 to shake, so that the screening screen 20 can screen out the small concrete sand and gravel particles again.

[0031] During equipment operation, the water inlet pump 14 can extract the coolant in the cooling tank 11 through the water inlet pipe 15 and transport it to the hollow jacket 8. The water pump 12 can extract the coolant in the hollow jacket 8 and transport it back to the cooling tank 11 through the drain pipe 13, thereby circulating and removing the heat generated by friction during the long-term high-speed operation of the rotary feeder 2.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
