Description

Technical Field

[0001] The utility model relates to the technical field of waste recovery devices, and more particularly to a waste recovery device for construction engineering. Background Art

[0002] With the accelerating pace of urbanization, not only are cities undergoing rapid transformation, but the construction industry is also experiencing unprecedented rapid growth. Against this backdrop, demand for concrete, the cornerstone of modern cities, has skyrocketed, making it the primary consumer of non-renewable natural resources such as cement, sand, pebbles, and gravel. At the same time, with urban expansion and renewal, a large number of older buildings, structures, and urban infrastructure are facing demolition due to disrepair, functional degradation, or reaching the end of their service life. This process not only marks a new chapter in urban development, but has also quietly spawned a massive market for construction and demolition waste.

[0003] As for construction waste, most of them are now directly landfilled without any treatment, which results in a large amount of resource waste. Moreover, landfilling causes geological changes and damages the environment. Recycling and reusing construction waste after treatment is a reasonable way and method to solve the problem of construction waste. This can not only protect natural resources but also reduce the impact of construction waste on the environment. Due to the wide variety of types of construction waste, separation should be carried out when crushing and recycling, but the existing construction waste crushers have poor separation effect and cannot fully separate the waste. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a waste recycling device for construction engineering to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a waste recycling device for construction projects, comprising a recycling device body, a motor box fixedly connected to one side of the top of the recycling device body, a movable plate fixedly connected to the inside of the recycling device body, a transmission rack fixedly connected to the bottom of the movable plate, a motor fixing plate provided at the bottom of the movable plate, a second motor fixedly connected to one side of the motor fixing plate, a transmission gear fixedly connected to one side of the second motor, a connecting rod fixedly connected to one side of the movable plate, a reset spring provided on the outer side of the connecting rod, a movable rod fixedly connected to the top of the movable plate, and a connecting frame fixedly connected to the top of the movable rod.

[0006] Furthermore, support feet are fixedly connected around the bottom of the recovery device body, a first discharge pipe is fixedly connected to the bottom of the recovery device body, a recovery device door is provided on one side of the recovery device body, a door handle is fixedly connected to one side of the recovery device door, a feed pipe is fixedly connected to the top of the recovery device body, a second discharge pipe is fixedly connected to one side of the bottom of the recovery device body, an inclined plate is fixedly connected to the bottom of the recovery device body, a blowing pipe is fixedly connected to one side of the recovery device body, and a crushing pipe is fixedly connected to the bottom of the feed pipe.

[0007] Furthermore, a triangular support frame is fixedly connected to the bottom of the motor box, a first motor is provided inside the motor box, a transmission shaft is fixedly connected to one side of the first motor, a fixing ring is fixedly connected around the transmission shaft, and crushing rods are evenly fixedly connected around the fixing ring.

[0008] Furthermore, the second motor engages with the transmission rack when rotating, fixing holes are provided inside the movable rod and the connecting frame, and the movable rod and the connecting frame are connected using a connecting column.

[0009] Furthermore, a feed hole and a discharge hole are provided at the top and bottom of the recovery device body.

[0010] Furthermore, a placement hole is provided inside the motor box, and the surface of the crushing rod is provided with a hard and wear-resistant coating.

[0011] Technical effects and advantages of this utility model:

[0012] The utility model is provided with a transmission device, and the second motor rotates so that the transmission gear and the transmission rack engage with each other, thereby moving the movable plate toward the second discharge pipe, causing the waste to flow out from the second discharge pipe. When the second motor continues to rotate, the transmission gear will no longer engage with the transmission rack, and the movable plate will be pulled back by the reset spring to continue to receive the waste and promptly move the waste out of the recovery device body. The timely removal of the waste can ensure the continuous operation of the grinding device, avoid the downtime for cleaning due to the accumulation of waste, and thus improve the overall production efficiency.

[0013] The utility model is provided with a crushing device, waste is placed into a feed pipe, and the transmission shaft is rotated by a first motor, so that the crushing rod grinds the waste. Through the crushing and grinding, different components in the waste are broken and refined, and their surface area is significantly increased, which is helpful for subsequent separation processes such as filtration, sedimentation, centrifugation, etc., because the larger contact area improves the separation efficiency between components.
