Description

Technical Field

[0001] This utility model relates to the technical field of production of recycled asphalt concrete from construction waste, and in particular to a storage tank for recycled aggregates from construction. Background Technology

[0002] Construction and demolition generate a large amount of construction waste. The indiscriminate dumping and disposal of this waste negatively impacts the environment. Currently, the most widely used and environmentally friendly treatment method is to crush and recycle construction waste as recycled aggregate for reuse in engineering projects. Recycled aggregate is a granular material produced from construction waste such as concrete and bricks through crushing and screening processes. Based on particle size, it is divided into recycled coarse aggregate (>4.75mm) and recycled fine aggregate (≤4.75mm), which can replace natural aggregate in applications such as roadbed soil improvement, mortar preparation, and recycled concrete. Its production process includes pretreatment to separate impurities, multi-stage crushing, particle size screening, and surface modification. Technological improvements can enhance screening efficiency and environmental performance.

[0003] Currently, recycled aggregates are typically stored in various tanks before being used in asphalt concrete mixing. However, the materials in each tank are from the same batch. Due to the influence of waste raw materials and process conditions, there are still slight differences in the performance indicators between different batches of materials. As a result, the quality of the materials discharged through the auger varies, which is not suitable for the application of large quantities of recycled aggregates from different batches in asphalt concrete and needs to be improved. Utility Model Content

[0004] The problem this utility model aims to solve is to provide a building recycled aggregate storage tank that addresses the aforementioned deficiencies in the existing technology and is suitable for mixing different batches of recycled aggregate.

[0005] The above-mentioned objective of this utility model is achieved through the following technical solution: A recycling aggregate storage tank for construction includes a tank body, a plurality of partitions disposed within the tank body and arranged around an axis, an end cap rotatably connected to the top of the tank body, a rotary drive mechanism disposed between the tank body and the end cap, a feed pipe passing through the end cap, and a conveying pipe connected to the feed pipe via a rotary joint. The partitions divide the interior of the tank body into a plurality of fan-shaped cavities. The axis of the tank body coincides with the rotation axis of the rotary drive mechanism and the rotary joint. The moving path of the feed pipe passes sequentially above these fan-shaped cavities.

[0006] By adopting the above technical solution, different batches of recycled aggregate are conveyed by the feeding auger and then sequentially enter each sector-shaped cavity through the conveying pipe and the feeding pipe. As the end cap rotates under the drive of the rotary drive mechanism, the moving path of the feeding pipe passes above these sector-shaped cavities in sequence, allowing different batches of aggregate to enter each sector-shaped cavity separately. During subsequent discharge, the different batches of aggregate in each sector-shaped cavity will be mixed together and output through the discharge auger at the bottom of the storage tank. This solves the problem of slight differences in the performance indicators of different batches of materials and uneven material quality after discharge in the existing technology, and is suitable for the application of large quantities of different batches of recycled aggregate in asphalt concrete. Furthermore, the centerline of the tank body coincides with the rotation centerline of the rotary drive mechanism and the rotary joint, ensuring the stability of the tank body rotation and the smoothness of feeding, reducing the probability of failure during equipment operation, and improving the efficiency and reliability of the entire production process.

[0007] The present invention is further configured such that the bottom of the tank is a tapered opening.

[0008] By adopting the above technical solution, the tapered opening design enables recycled aggregates to gather more smoothly towards the discharge port under the action of gravity, thereby accelerating the discharge speed and improving the unloading efficiency. Moreover, during the discharge process, the shape of the tapered opening can guide the aggregates to a certain extent, allowing them to be discharged in a more concentrated and orderly manner. This avoids the accumulation and blockage of aggregates at the bottom of the tank, which helps to reduce the amount of residual aggregates in the tank and improve the utilization rate of the tank.

[0009] The present invention is further configured such that: the rotary drive mechanism includes a gear ring disposed on the tank body, a reduction motor disposed on the end cover, and a gear disposed on the output shaft of the reduction motor and meshing with the gear ring.

[0010] By adopting the above technical solution, the geared motor can provide stable power for the rotation of the tank. When the geared motor starts, its output shaft drives the gear to rotate. Since the gear and the gear ring mesh with each other, the rotation of the gear will drive the gear to move further along the gear ring, thereby driving the end cover to rotate. This transmission method through the meshing of gears and gear rings can ensure the stability and accuracy of power transmission, so that the feed pipe can rotate at a predetermined speed and direction. In addition, by adjusting the speed and number of revolutions of the geared motor, the rotation of the feed pipe can be easily controlled to adapt to the feeding requirements of different batches of materials.

[0011] The present invention is further configured to include an exhaust fan, which is mounted on the end cover with its air inlet facing the fan-shaped cavity.

[0012] By adopting the above technical solution, the exhaust fan can expel the air from the fan-shaped cavity and form an airflow, which helps to reduce the humidity and temperature in the fan-shaped cavity and create a more suitable environment for aggregate storage. If recycled building aggregate is stored in a humid and hot environment, it may clump or deteriorate, affecting its subsequent performance. The exhaust fan can effectively avoid these problems.

[0013] The present invention is further configured to include a rotary motor disposed on the end cover and a circulating fan disposed on the output shaft of the rotary motor.

[0014] By adopting the above technical solution, the rotary motor can drive the circulating fan to rotate. The airflow generated by the rotating fan can form a circulation inside the tank. This air circulation helps to make the temperature and humidity of various areas inside the tank more uniform, avoiding local overheating or excessive humidity. A uniform temperature and humidity environment is very important for the storage of recycled building aggregates. It can further prevent aggregates from clumping and deteriorating, and improve the storage quality of aggregates.

[0015] The present invention is further configured such that the blades of the circulating fan are propeller blades.

[0016] By adopting the above technical solution, the propeller blade has a higher axial thrust, which can drive the air flow more efficiently when rotating, thereby enhancing the air circulation effect in the tank. Compared with other types of blades, the propeller blade can make the air form a stable circulation path in the tank more quickly, allowing the air in different areas to exchange and mix more frequently. This enables the temperature and humidity in the tank to reach a uniform state in a shorter time, further improving the stability of the storage environment for recycled building aggregates.

[0017] In summary, the beneficial technical effects of this utility model are as follows: the building recycled aggregate storage tank, through its unique structural design, effectively solves the problems existing in the prior art, realizes the mixing of different batches of recycled aggregate, and improves the quality stability of the discharged material.

[0022] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figure 1 This utility model discloses a recycling aggregate storage tank for construction, comprising a tank body 1, four partitions 2 arranged inside the tank body 1 around an axis, an end cap 3 rotatably connected to the top of the tank body 1, a rotary drive mechanism 4 disposed between the tank body 1 and the end cap 3, a feed pipe 5 passing through the end cap 3, and a conveying pipe 7 connected to the feed pipe 5 via a rotary joint 6. The bottom of the tank body 1 is designed as a tapering opening. The partitions 2 divide the interior of the tank body 1 into multiple fan-shaped cavities. The axis of the tank body 1 coincides with the rotation axis of the rotary drive mechanism 4 and the rotary joint 6. The movement path of the feed pipe 5 passes sequentially above these fan-shaped cavities.

[0024] Different batches of recycled aggregate are conveyed by the feeding auger and then sequentially enter the various sector-shaped cavities through the conveying pipe 7 and the feeding pipe 5. As the end cap 3 rotates under the drive of the rotary drive mechanism 4, the moving path of the feeding pipe 5 passes over these sector-shaped cavities in sequence, allowing different batches of aggregate to enter each sector-shaped cavity separately. During subsequent discharge, the different batches of aggregate in each sector-shaped cavity will be mixed together and output through the discharge auger at the bottom of the storage tank. This solves the problem of slight differences in the performance indicators of different batches of materials and uneven material quality after discharge in the existing technology, and is suitable for the application of large quantities of different batches of recycled aggregate in asphalt concrete. Furthermore, the axis of the tank body 1 coincides with the rotation axis of the rotary drive mechanism 4 and the rotary joint 6, ensuring the stability of the rotation of the tank body 1 and the smoothness of the feeding, reducing the probability of failure during equipment operation, and improving the efficiency and reliability of the entire production process. The tapered opening design allows recycled aggregate to gather more smoothly towards the discharge port under gravity, accelerating the discharge speed and improving unloading efficiency. Moreover, during the discharge process, the shape of the tapered opening can guide the aggregate, allowing it to be discharged in a more concentrated and orderly manner, avoiding the accumulation and blockage of aggregate at the bottom of tank 1. This helps reduce the amount of residual aggregate in tank 1 and improves the utilization rate of tank 1.

[0025] Reference Figure 2 and Figure 3The rotary drive mechanism 4 includes a gear ring 41 mounted on the tank body 1, a reduction motor 42 mounted on the end cover 3, and a gear 43 mounted on the output shaft of the reduction motor 42 and meshing with the gear ring 41. The reduction motor 42 provides stable power for the rotation of the tank body 1. When the reduction motor 42 starts, its output shaft drives the gear 43 to rotate. Since the gear 43 meshes with the gear ring 41, the rotation of the gear 43 drives the gear 43 to move further along the gear ring 41, thereby driving the end cover 3 to rotate. This transmission method through the meshing of the gear 43 and the gear ring 41 can ensure the stability and accuracy of power transmission, allowing the feed pipe 5 to rotate at a predetermined speed and direction. In addition, by adjusting the speed and number of revolutions of the reduction motor 42, the rotation of the feed pipe 5 can be easily controlled to adapt to the feeding requirements of different batches of materials.

[0026] The end cover 3 is also equipped with an exhaust fan 8, a rotary motor 9, and a circulating fan 10 mounted on the output shaft of the rotary motor 9. The exhaust fan 8 is installed on the end cover 3 with its air inlet facing the fan-shaped cavity, and the blades of the circulating fan 10 are designed as propeller blades. The exhaust fan 8 can exhaust the air in the fan-shaped cavity, creating airflow. This helps to reduce the humidity and temperature in the fan-shaped cavity, creating a more suitable environment for aggregate storage. If recycled construction aggregate is stored in a humid and hot environment, it may clump or deteriorate, affecting its subsequent performance. The exhaust fan 8 can effectively prevent these problems. The rotary motor 9 drives the circulating fan 10 to rotate. The airflow generated by the rotating circulating fan 10 can circulate inside the tank 1. This air circulation helps to make the temperature and humidity in various areas of the tank 1 more uniform, avoiding localized high temperatures or high humidity. A uniform temperature and humidity environment is very important for the storage of recycled construction aggregate, as it can further prevent aggregate clumping and deterioration, improving the quality of aggregate storage. The propeller blades have high axial thrust and can drive airflow more efficiently when rotating, thereby enhancing the air circulation effect inside the tank 1. Compared with other types of blades, the propeller blades can make the air form a stable circulation path in the tank 1 more quickly, allowing the air in different areas to exchange and mix more frequently. This enables the temperature and humidity inside the tank 1 to reach a uniform state in a shorter time, further improving the stability of the storage environment for recycled building aggregates.
