Description

Technical Field

[0001] This utility model relates to a device for recycling construction waste. Background Technology

[0002] In the process of modern urbanization, with the advancement of various construction, demolition, and municipal engineering projects, a large amount of construction waste is generated during construction. This includes primary waste such as concrete blocks, bricks, stones, wood, plastics, and metal materials, as well as secondary waste such as sand and debris adhering to these primary wastes. During the recycling steps of crushing and sorting primary waste, the presence of large amounts of secondary waste such as sand and debris often leads to serious dust problems and environmental non-compliance. Furthermore, these secondary wastes are often rich in high-quality reusable building materials; failure to recycle them not only increases the environmental burden but also wastes valuable resources.

[0003] Patent CN120054926A discloses a construction waste recycling device and processing method. The disclosed construction waste recycling device includes a secondary waste recycling and processing line. A high-pressure washing assembly washes the secondary waste off the main waste and temporarily stores it in a transition box. A lifting belt lifts the secondary waste with a large amount of moisture on its surface from the transition box to a filtration device for drying. A feeding auger discharges the dried secondary waste from the filtration device. This process achieves the cleaning, drying, and recycling of secondary waste such as sand and debris adhering to construction waste, effectively improving the environmental problems caused by secondary waste. However, this secondary waste recycling and processing line still has some drawbacks: 1. The water collection tank is also equipped with a transmission mechanism that provides power to the lifting belt. During the process of the lifting belt conveying the waste material with a large amount of moisture on its surface to the water filtration device for drying, some of the liquid containing usable waste material can easily flow away from both sides of the lifting belt, causing waste material particles to enter the transmission mechanism and causing wear or jamming. In addition, once the transmission mechanism wears or jams, it can easily lead to a chain reaction such as the lifting belt running off-center, unstable operation, or even wear during operation.

[0004] 2. The solid waste from the leaked liquid gradually accumulates and settles at the bottom of the water collection tank, causing the water storage capacity of the tank to gradually decrease, resulting in an increase in the frequency of shutdown for dredging. Utility Model Content

[0005] The purpose of this utility model is to provide a construction waste recycling device to solve the above-mentioned technical problems.

[0006] The technical solution of this utility model is as follows: A construction waste recycling device includes a secondary waste production and recycling device, which includes a transition box, a lifting belt, and a water collection tank. The transition box and the water collection tank are separated by a partition wall. A filter frame is provided near the top of the water collection tank. An opening is provided in the partition wall. The input end of the lifting belt is located at the bottom of the transition box, and the output end of the lifting belt passes through the opening and receives the top of the filter frame. Vertical plates are provided at equal intervals on the surface of the lifting belt to prevent secondary waste from moving downward along the lifting belt. A water receiving trough with an upward opening is also provided in the partition wall. The water receiving trough passes through the opening and is located at the lower part of the lifting belt. The upper edges of the opening of the water receiving trough extend beyond the lifting belt to ensure that the water receiving trough can receive the liquid flowing out from both sides of the lifting belt. Rollers are installed at equal intervals on the edge of the lifting belt, and a sliding groove is provided on the inner side of the water receiving trough to slide with the rollers.

[0007] The beneficial effects of this technical solution are as follows: By setting a water receiving trough below the elevator belt, the liquid containing usable byproducts leaking from both sides of the elevator belt returns to the transition box along the trough, preventing byproduct particles from entering the transmission mechanism and causing jamming or damage. By setting a sliding groove inside the water receiving trough and rollers on the elevator belt, the sliding cooperation of the trough and rollers ensures that the elevator belt always runs stably inside the water receiving trough, avoiding problems such as belt deviation, unstable operation, or even wear during operation. Furthermore, this technical solution also solves the problem of reduced water storage capacity of the water collection tank due to the accumulation and settling of byproduct particles at the bottom.

[0008] Furthermore, the width of the upright plate is smaller than the width of the lifting belt.

[0009] The beneficial effects of this technical solution are: setting the width of the vertical plate to be less than the width of the lifting belt can avoid collision and friction between the vertical plate and the water receiving tank, which could damage the lifting belt. At the same time, the leaked liquid can flow back to the transition box from the gap between the vertical plate and the water receiving tank.

[0010] Furthermore, the surface of the upright plate is provided with water filter holes.

[0011] The beneficial effects of this technical solution are: during the operation of the elevator belt, excess water in the slurry can be filtered out in time through the water filter holes on the surface of the vertical plate, so that as much solid waste as possible remains on the elevator belt and is not carried away by the water flow, thereby improving production efficiency.

[0012] Furthermore, the water receiving tank includes a bottom plate and a side plate, the bottom plate and the side plate are perpendicular, and the upper surface of the side plate is an inwardly inclined slope. Attached Figure Description

[0017] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0018] A specific embodiment of the construction waste recycling device of this utility model: A construction waste recycling device includes a main waste production and recycling device and a secondary waste production and recycling device, wherein the main waste production and recycling device is prior art and includes a lightweight material sorting device, a crushing device and a metal sorting device, etc., which will not be described in detail here.

[0019] like Figure 1 As shown, the secondary waste production and recycling device includes a transition box 2, a lifting belt 4, a conveying roller 43, a water collection bin 1, and a power unit 7. In this embodiment, the power unit 7 includes a drive shaft, a drive belt, a pulley, and a reduction motor.

[0020] like Figure 1 As shown, the transition box 2 and the water collection tank 1 are separated by a partition wall 3. A filter frame 6 is provided near the top of the water collection tank 1. An opening 31 is provided on the partition wall 3. The input end of the lifting belt 4 is located at the bottom of the transition box 2, and the output end of the lifting belt 4 passes through the opening 31 and is received at the top of the filter frame 6. The surface of the lifting belt 4 is provided with vertical plates 41 at equal intervals to prevent secondary waste from moving downward along the lifting belt 4. The partition wall 3 is also provided with an upward-opening water receiving trough 5. The water receiving trough 5 passes through the opening 31 and is located at the lower part of the lifting belt 4. The upper edges of the openings of the water receiving trough 5 extend beyond the lifting belt 4 to ensure that the water receiving trough 5 can receive the liquid flowing out from both sides of the lifting belt 4. Rollers 42 are installed at equal intervals on the edge of the lifting belt 4. A sliding groove 51 is provided on the inner side of the water receiving trough 5 to slide with the rollers 42.

[0021] During use, the lifting belt 4 transports the secondary waste in the transition box 2 to the water filter frame 6 to remove water. During the operation of the lifting belt 4, the liquid containing usable secondary waste that leaks from both sides of the lifting belt 4 returns to the transition box 2 along the water receiving trough 5. Through the sliding cooperation of the chute 51 and the roller 42, the lifting belt 4 always runs stably inside the water receiving trough 5.

[0022] like Figures 2-3 As shown, the width of the vertical plate 41 is smaller than the width of the lifting belt 4, and the surface of the vertical plate 41 is provided with filter holes. The width of the vertical plate 41 is smaller than the width of the lifting belt 4 to prevent collision and friction between the vertical plate 41 and the water receiving tank 5, which could damage the lifting belt 4. Simultaneously, leaked liquid can flow back to the transition box 2 through the gap between the vertical plate 41 and the water receiving tank 5. The filter holes on the surface of the vertical plate 41 allow excess water in the liquid to be filtered out promptly during the conveying process of the lifting belt 4, ensuring that as much solid waste as possible remains on the lifting belt 4 and is not carried away by the water flow, thereby improving production efficiency.

[0023] In this specific example, such as Figure 3As shown, the water receiving tank 5 includes a bottom plate 52 and a side plate 53. The bottom plate 52 and the side plate 53 are perpendicular to each other. The upper surface of the side plate 53 is set as an inwardly inclined slope to ensure that the upper edges of the openings on both sides of the water receiving tank 5 extend beyond the lifting belt 4.

[0024] In other embodiments, such as Figure 4 As shown, the angle between the base plate 52 and the side plate 53 is greater than 90 degrees.

[0025] In other embodiments, such as Figure 5 As shown, the water receiving tank 5 is an arc shape with its opening facing upwards.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
