Description

Technical Field

[0001] The invention relates to a reinforced concrete separation and recovery device, belonging to the technical field of reinforced concrete. Background Art

[0002] Reinforced concrete is a widely used building material in modern construction. Its main components include cement, sand, crushed stone and steel bars. As a base material, concrete has good compressive strength, while steel bars provide excellent tensile strength and toughness. This composite material combines the advantages of both and is widely used in various building structures. Common applications of reinforced concrete include high-rise buildings, bridges, roads, tunnels, dams and various infrastructures.

[0003] With the advancement of urbanization, the demolition of old buildings has become more and more common. However, during the demolition process, reinforced concrete structures are mixed together, which makes their recycling face major challenges.

[0004] During the demolition of buildings, reinforced concrete is often difficult to separate and recycle effectively due to its complex composition. The crushed stone, sand and steel bars in the concrete are mixed together, making the separation process complicated and time-consuming. This not only causes a large amount of waste of building materials, but also prevents the effective use of recyclable resources.

[0005] For mixed materials that cannot be separated, traditional waste treatment methods often require a lot of resources and time. For example, the entire concrete block needs to be initially processed through processes such as crushing and screening, and then further technical means are used to separate the steel bars and concrete fragments. The complexity of these processes directly leads to an increase in treatment costs.

[0006] During the demolition process, the steel-concrete structure inside the building is usually highly combined, which makes it extremely difficult to separate the steel bars from the concrete. Although traditional physical methods such as crushing and screening can process concrete, the separation of steel bars requires more technical means, which greatly reduces the overall recycling efficiency. Summary of the invention

[0007] Purpose of the invention: In view of the deficiencies in the prior art, the present invention provides a steel bar and concrete separation and recovery device. The present invention uses a separation device and a crushing device to separate and crush the steel bar and concrete respectively, thereby achieving the separation and recovery of the steel bar and concrete.

[0008] Technical solution: A reinforced concrete separation and recovery device, including a device body and a controller. The device body is provided with a first chamber and a second chamber that are independent of each other. The first chamber is provided with a separation device, the second chamber is provided with a crushing device, and a mutually communicating partition device is provided between the first chamber and the second chamber. The controller is signal-connected with the separation device, the crushing device, and the partition device. The first chamber is provided with a feed port, and the second chamber is provided with a discharge port.

[0009] The present invention provides a separation device and a crushing device. The separation device is used to perform preliminary separation on the reinforced concrete in the first chamber, separate the steel bars and the concrete, and then open the partition device to send the concrete into the second chamber, grind and crush the concrete through the crushing device for recycling. After the concrete is sent into the second chamber, the partition device is closed, and the separation device places the steel bars on the partition device. When the concrete is completely recovered through the discharge port, the crushing device is closed, the partition device is opened, and the steel bars are sent into the second chamber for recycling through the discharge port.

[0010] Furthermore, in order to realize independent operation of each chamber, the partition device includes a first partition, a second partition, and a first motor. One ends of the first partition and the second partition are detachably connected, and the other ends are respectively transmission-connected to the first motor.

[0011] Furthermore, in order to achieve separation of the steel bars, the separation device includes an electromagnetic adsorption unit, a second motor, and a telescopic arm. The electromagnetic adsorption unit, the telescopic arm, and the second motor are connected in sequence, and the second motor is connected to a controller signal.

[0012] Furthermore, in order to prevent interference between the steel bar recovery and the crushing device, a third chamber is provided between the first chamber and the second chamber, and a partition device is provided between the third chamber and the first chamber and the second chamber, respectively, and the third chamber is provided with a steel bar recovery device.

[0013] In the initial state, the partitions between the first and third chambers are closed, and the partitions between the third and second chambers are open. This is to facilitate the concrete to fall directly into the second chamber. The partitions between the third and second chambers are closed only when the steel bars are subsequently processed.

[0014] Furthermore, in order to realize the recycling of steel bars, the steel bar recycling device includes a third motor, a telescopic rod and a push plate connected in sequence, and an inlet unit and an outlet unit are respectively provided on the relative inner walls of the third chamber along the pushing direction, and the inlet unit, the outlet unit and the third motor are respectively connected to the controller signal, and the inlet unit and the outlet unit are respectively detachably connected to the device body to form a closed third chamber.

[0015] The third motor drives the telescopic rod to enable the push plate to push the steel bars in the third chamber to the outlet unit, and the push plate is reset after the discharge is completed, thereby realizing the recovery of the steel bars.

[0016] Furthermore, in order to separate the concrete adhering to the steel bars, a vibration device is also provided in the third chamber, and the vibration device includes a vibration baffle, a vibration motor, and a spring which are spliced ​​to each other. The vibration baffle is respectively arranged corresponding to the first baffle and the second baffle between the third chamber and the second chamber. One end of the spring is connected to the vibration baffle, and the other end is connected to the first baffle and the second baffle between the third chamber and the second chamber. The vibration motors are respectively arranged at the bottom of the vibration baffles and connected to the controller signal. The two ends of the vibration baffle are respectively abutted against the inner wall of the third chamber.

[0017] The steel bars are vibrated by the vibrating partition so that the adhered concrete falls off, thereby achieving the precise separation of the steel bars and concrete. At the same time, the vibrating partition is connected to the first partition and the second partition by a spring, which can reduce the vibration sensation on the first partition and the second partition and reduce wear. Moreover, the vibrating partition can be separated as the first partition and the second partition are separated to avoid hindering the falling of the concrete.

[0018] Furthermore, in order to further screen out the adhered concrete, sieve holes are respectively provided on the vibration partition and the first partition and the second partition between the third chamber and the second chamber.

[0019] While the steel bars are vibrating, the broken concrete will fall through the sieve holes into the second chamber. At the same time, in order to prevent the concrete from interfering with the spring components, after the steel bars are recovered, the first and second partitions between the third and second chambers can be opened to send the concrete stored on the first and second partitions into the second chamber.

[0020] Furthermore, in order to push the steel bar recovery by the push plate, the import unit includes an import door panel, an import cavity, a fourth motor, a gear part and a screw. The import door panel is arranged in the import cavity. The fourth motor drives the screw through the gear part to drive the import door panel to move back and forth. The fourth motor is connected to the controller signal.

[0021] Furthermore, in order to push the steel bar recovery by the push plate, the outlet unit includes an outlet door plate and a fifth motor, and the fifth motor drives the outlet door plate to flip toward the outside of the device body.

[0022] Furthermore, in order to crush and recycle concrete, the crushing device includes a sixth motor and a crushing rotating unit, and the sixth motor is transmission-connected to the crushing rotating unit.

[0023] Beneficial effects: The present invention performs preliminary separation of reinforced concrete through the first chamber and the separation device, then sends the concrete into the second chamber for crushing, sends the steel bars into the third chamber for vibration treatment, separates the adhered concrete, and sends it into the third chamber through the sieve holes, and then uses a push plate to send out the processed steel bars, thereby realizing the recycling of reinforced concrete.
