[0001] The present application relates to the technical field of construction waste utilization, and specifically to a device for preparing recycled concrete using construction waste. Background Art
[0002] With the acceleration of urbanization, the construction, reconstruction and demolition of a large number of buildings have generated a large amount of construction waste. These wastes not only occupy precious land resources, but also cause environmental pollution if improperly handled. In recent years, people have begun to explore effective ways to deal with construction waste, among which converting waste into recycled concrete has become an important way of resource utilization.
[0003] However, traditional processing methods often require the coordinated use of multiple machines with different functions, resulting in complex and cumbersome processes, which in turn leads to low overall processing efficiency. In addition, due to the high level of manual intervention, human errors are prone to occur, making it difficult to ensure the consistency and stability of recycled concrete. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the present application provides a device for preparing recycled concrete using construction waste, which has the advantages of improving equipment automation, and solves the problem that traditional processing methods often require the coordinated use of multiple machines with different functions, resulting in complicated and cumbersome processes, which in turn leads to low overall processing efficiency. Due to the high level of manual intervention, human errors are easily generated, making it difficult to ensure the consistency and stability of recycled concrete.
[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a device for preparing recycled concrete using construction waste, comprising a first shell and a sieve plate, the outer walls of the sieve plate are fixedly connected to a plurality of rubber columns arranged in a linear array, both sides of the sieve plate are fixedly connected to a vibration motor, a collecting plate is fixedly connected to the inside of the first shell, two mirror-distributed brackets are fixedly connected to both sides of the inside of the first shell, a discharge pipe is fixedly connected between four brackets in groups of two, a screw is rotatably connected to the inside of the discharge pipe, one end of the discharge pipe passing through the first shell is fixedly connected to a fixed plate, the end of the fixed plate away from the discharge pipe is fixedly connected to a grinding ring, one side of the fixed plate is fixedly connected to a second shell, the inner wall of the second shell is fixedly connected to a rotating ring, the inner wall of the second shell is rotatably connected to a grinding knife, and the outer wall of the grinding knife is provided with a slide groove.
[0006] Through the above scheme, the sieve plate is connected to the first shell through the rubber column and is equipped with a vibration motor, which can efficiently screen the construction waste and separate particles of different sizes. The vibration also helps to clean the residue on the sieve plate, prevent blockage, and improve the screening efficiency. The screw in the discharge pipe not only plays the role of conveying materials, but also can perform preliminary extrusion and crushing of the materials to make them more uniform. The combination of the grinding ring and the grinding knife can further refine the materials to ensure that the particle size of the raw materials of the recycled concrete meets the requirements. The device integrates the screening function and the grinding function, thereby improving the degree of automation of the device, so that the useful components in the construction waste can be effectively extracted, reducing resource waste and promoting the recycling of resources.
[0007] Furthermore, a crushing box is fixedly connected to one side of the upper end of the first shell, two crushing rollers arranged in a mirror-image distribution are rotatably connected inside the crushing box, and a feed plate is fixedly connected to one side of the crushing box.
[0008] Through the above solution, the two mirror-imaged crushing rollers set inside the crushing box can pre-process the construction waste entering the device and crush it into smaller particles. This step provides more uniform raw materials for subsequent screening and grinding, improving the overall processing efficiency.
[0009] Furthermore, a waste box is fixedly connected to one side of the first shell, and a sliding box is slidably connected to the bottom end of the waste box.
[0010] Through the above solution, the waste box and the sliding box inside it provide suitable storage space for the waste generated during the processing process. The design of the sliding box makes it easier to collect and clean up the waste, which helps to maximize the utilization of resources and reduce waste.
[0011] Furthermore, a plurality of legs distributed in a rectangular array are fixedly connected to the bottom end of the first shell.
[0012] Through the above solution, the arrangement of the supporting legs is used to provide stable support for the first shell.
[0013] Furthermore, one end of the plurality of rubber columns away from the sieve plate is fixedly connected to the inner wall of the first shell, and the sieve plate is fixedly arranged inside the first shell.
[0014] Through the above solution, since the sieve plate is fixedly connected to the inner wall of the first shell through multiple rubber columns, this design not only enhances the stability of the sieve plate, but also reduces vibration noise during the screening process.
[0015] Furthermore, the bottom end of the collecting plate is fixedly connected to the feed port.
[0016] Through the above solution, the fixed connection between the bottom end of the collecting plate and the feed port ensures that the screened material can smoothly enter the subsequent processing flow.
[0017] Furthermore, the grinding ring corresponds to the grinding knife, and the rotating ring is rotatably arranged inside the sliding groove.
[0018] Through the above solution, the corresponding design of the grinding ring and the grinding knife ensures that the material can be fully ground and refined when passing through, and the position of the grinding knife is fixed by the rotating ring, thereby obtaining a more uniform particle size.
[0019] Furthermore, one end of the sieve plate passes through the first shell and extends into the interior of the waste box.
[0020] Through the above solution, the design of extending one end of the sieve plate into the interior of the waste box allows the waste generated during the screening process to fall directly into the waste box without the need for additional transmission equipment. Since the waste can be directly collected in the waste box, it can be more convenient for subsequent processing or recycling.
[0021] Compared with the existing technology, the technical solution of this application has the following beneficial effects:
[0022] This device for preparing recycled concrete using construction waste has a sieve plate connected to a first shell via a rubber column and is equipped with a vibration motor, which can efficiently screen construction waste and separate particles of different sizes. Vibration also helps to clean residues on the sieve plate, prevent blockage, and improve screening efficiency. The screw in the discharge pipe not only serves to transport materials, but also performs preliminary extrusion and crushing of the materials to make them more uniform. The combination of the grinding ring and the grinding knife can further refine the materials to ensure that the particle size of the raw materials of the recycled concrete meets the requirements. The device integrates the screening function and the grinding function, thereby improving the degree of automation of the device, enabling the effective extraction of useful components in construction waste, reducing resource waste, and promoting the recycling of resources.

[0036] The working principle of the above embodiment is:
[0037] The construction waste is fed into the crushing box 16 through the feed plate 18. Inside the crushing box 16, two crushing rollers 17 arranged in a mirror image start working to perform preliminary crushing on the construction waste and crush it into smaller particles. The preliminarily crushed materials fall onto the screen plate 2.
