Description

Technical Field

[0001] The utility model relates to the technical field of concrete recycling, in particular to a concrete waste separation device. Background Art

[0002] With the continuous development of the economy and society, the process of urbanization is getting faster and faster, and a large amount of concrete is used in urban construction. The number of concrete mixing stations is also increasing. However, concrete mixing stations will inevitably produce a large amount of concrete waste, which will cause environmental damage if directly discharged. At present, the concrete waste in concrete mixing stations is mainly reused through concrete waste recycling devices to reduce the pollution of concrete waste to the environment.

[0003] At present, when recycling concrete, screening is usually used to separate gravel and cement in waste concrete. After screening, although cement can be discharged through the screen, the gravel in the screen needs external force to be discharged, which leads to the need to configure an additional discharge mechanism for the discharge of gravel. The discharge mechanism is mostly arranged in the screening device, which will be subject to a certain degree of wear during screening and increase maintenance costs. Therefore, a concrete waste separation device is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a concrete waste separation device, which has the advantage of quickly removing the stones left after screening without the help of external force, and solves the problem that the stones remaining after concrete screening need to rely on external force when discharging and the discharge structure is easily worn during the screening operation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete waste separation device, comprising a connecting pipe and a bottom plate, the bottom end of the connecting pipe is bifurcated and connected with a screening cylinder respectively, a reinforcement ring is fixedly installed on the connecting pipe, and support frames are fixedly installed at the front and rear ends of the reinforcement ring respectively, and also includes a sealing cover;

[0009] Wherein, electric telescopic rods are fixedly installed at both ends of the connecting rod close to the sealing cover.

[0010] When using a concrete waste separation device in the technical solution, the bottom plate is fixedly installed on the equipment foundation to ensure the stability of the entire device, and the concrete waste is added to the device through the feed trough. The radial longitudinal ribs on the inner wall of the feed trough help to disperse and guide the waste to flow to the connecting pipe, and the drive mechanism installed with the dispersion rack is started. The drive mechanism is fixedly installed on the sealing cover. The drive mechanism will drive the dispersion rack to rotate in the screening drum to help disperse the concrete waste. As the dispersion rack rotates, the concrete waste is separated in the screening drum. The screening drum adopts a trumpet-shaped structure, which is helpful for the separation and screening of materials, and can be discharged directly by gravity during discharge. The separated cement is discharged through the sieve holes on the screening drum and can be collected in the corresponding container or area. After the separation process is completed, the electric telescopic rod is started to move the sealing cover out of the screening drum, so as to discharge the gravel in the screening drum, and clean and maintain the screening drum and dispersion frame to ensure the sustainable and effective operation of the device. After cleaning and maintenance, the sealing cover is reset to ensure that the protrusion on the sealing cover is correctly matched with the inner side of the screening drum for the next use.

[0011] Preferably, a feed trough is installed on the top of the connecting pipe, longitudinal ribs are fixedly installed radially on the inner wall of the feeding trough, and the three ends of the connecting pipe are 120 degrees to each other.

[0012] The radial longitudinal ribs on the inner wall of the feed chute help to evenly disperse the waste and reduce accumulation and blockage. The design of the three ends of the connecting pipe being 120 degrees relative to each other may help to more evenly distribute the material flow to the screening cylinder.

[0013] Preferably, the screening cylinder adopts a trumpet-shaped structure, one end of the screening cylinder is connected and installed with a connecting pipe through a mounting bolt, and the other end of the screening cylinder is radially provided with a limiting groove.

[0016] The support frame is fixed to the base plate, and the base plate is fixed to the equipment foundation, providing a solid support to ensure the stability of the entire device during operation.

[0017] Preferably, protrusions are radially provided on the outer side of the sealing cover, the sealing cover is movably inserted into the inner side of the screening cylinder, and a bearing is embedded and installed at the center of the sealing cover.

[0018] The radial protrusions on the outer side of the sealing cover prevent the sealing cover from rotating after being inserted into the screening cylinder.

[0019] Preferably, one end of the dispersion frame passes through a bearing on the sealing cover and is drivingly installed with a driving mechanism, and the driving mechanism is fixedly installed on the sealing cover.

[0020] The dispersion frame is driven by the driving mechanism, which can efficiently disperse the materials and improve the separation efficiency.

[0021] Preferably, the end of the electric telescopic rod facing away from the connecting rod is fixedly connected to the support frame.

[0022] The electric telescopic rod provides a controllable pushing and pulling force. At the same time, electric control improves the convenience and safety of operation. Thus, it is convenient to open and close the sealing cover.

[0023] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0024] By setting the sealing cover, the present utility model inserts the sealing cover movably at one end of the screening cylinder away from the connecting pipe, opens a hole on the sealing cover and rotatably installs a dispersion frame, fixedly installs a connecting rod on the sealing cover, and fixedly installs electric telescopic rods at both ends of the connecting rod close to one side of the sealing cover.
