Description

Technical Field

[0001] The utility model relates to the technical field of construction waste treatment, and particularly relates to an environment-friendly construction waste treatment structure for construction projects. Background Art

[0002] During the construction process of construction projects, a large amount of construction waste will be generated, such as waste bricks, concrete blocks, wood, metal, etc. If these construction wastes are not properly treated, they will not only occupy a large amount of land resources, but also may cause environmental pollution. For example, components such as cement in waste concrete may generate dust in the natural environment, and rotten waste wood will breed bacteria, etc.

[0003] The existing treatment methods usually use a construction waste collection and treatment device to crush the construction waste, and then transport and transfer the crushed construction waste. However, if some construction waste absorbs rainwater after being rained on, construction wastewater will be generated when it is crushed again. If the waste containing construction wastewater is continuously transported and transferred, it is easy to cause the leakage of construction wastewater, thus causing environmental pollution;

[0004] The existing patent (publication number: CN214766021U) relates to an environment-friendly construction waste collection and treatment device for construction projects. It relates to the technical field of construction waste treatment, including a base, a box body, a crushing assembly, a filtering trough plate, and a collecting trough plate. The box body is arranged on the top surface of the base. The top surface of the box body is provided with a feed hopper. The crushing assembly is arranged inside the box body and is used to crush the construction waste entering the box body. The bottom surface of the box body is provided with a discharge port. The filtering trough plate is arranged on the base at a position between the discharge port and the top surface of the base. The collecting trough plate is arranged on the base at a position between the filtering trough plate and the top surface of the base. The side wall of the collecting trough plate is communicated with a water discharge trough plate. A filtering device for filtering construction wastewater is arranged on one side of the base near the water discharge trough plate. This application has the effect of being able to treat the construction wastewater during the process of treating the construction waste by the construction treatment device.

[0005] In view of the above problems, the existing patent gives a solution. The existing crushing devices for construction waste treatment usually feed materials manually. Since the feed inlet of the crushing device is generally set at the top of the device and is relatively high, it is rather laborious to manually put the construction waste into the crushing treatment device, and the labor intensity is relatively large. Moreover, after the existing crushing treatment device crushes the construction waste, it usually cannot classify and screen the waste with different particle sizes, which is not conducive to the subsequent treatment work of the waste.

[0006] Therefore, an environment-friendly construction waste treatment structure for construction projects is proposed. Summary of the Utility Model

On the left side of the top of the moving base 1, a classification and screening assembly 7 is provided;

[0029] The feeding assembly 6 includes two support frames 601. The bottom of the support frames 601 is fixedly connected to the top of the moving base 1. An electric conveyor belt 602 is arranged between the two support frames 601. A baffle 603 is fixedly connected to the surface of the electric conveyor belt 602. On the left side of the top of the two support frames 601, an electromagnetic separator 604 is provided.

[0030] In this embodiment: By setting the moving base 1, the crushing box 2, the crushing rollers 3, the feeding hopper 4, the discharge port 5, the feeding assembly 6 and the classification and screening assembly 7, during use, the entire device can be supported by the moving base 1 and can be conveniently moved, thereby improving the flexibility of the device. The building waste can be crushed through the crushing box 2 and the crushing rollers 3. The building waste can enter the crushing box 2 conveniently through the feeding hopper 4. The crushed building waste can be discharged from the crushing box 2 conveniently through the discharge port 5. Through the setting of the feeding assembly 6, it can assist workers in transporting the building waste into the crushing box 2, reducing the labor intensity of manual feeding. And during the transportation process, the metal impurities in the building waste can be separated, avoiding metal waste entering the crushing box 2 and damaging the equipment. Through the setting of the classification and screening assembly 7, the crushed building waste with different particle sizes can be classified and screened, thus bringing convenience to the subsequent treatment of the waste.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 5As shown in the figure, the classification and screening assembly 7 includes a support frame 701. At the top of the inner cavity of the support frame 701, a first screen plate 702 is provided. At the bottom of the first screen plate 702, a second screen plate 703 is provided. At the bottom of the second screen plate 703, a diversion plate 704 is provided. The sides of the first screen plate 702, the second screen plate 703, and the diversion plate 704 close to the inner wall of the support frame 701 are fixedly connected to the inner wall of the support frame 701 respectively.

[0032] Specifically, as Figure 1 , Figure 2 , Figure 5 shown, a vibration motor 705 is fixedly connected to the bottom of the support frame 701. Spring shock absorbers 706 are fixedly connected to the four corners of the bottom of the support frame 701. The bottom of the spring shock absorbers 706 is fixedly connected to the moving base 1.

[0033] Specifically, as Figure 2 , Figure 5 shown, a first blanking guide shell 707 is fixedly connected to the left side of the first screen plate 702. A second blanking guide shell 708 is fixedly connected to the left side of the second screen plate 703.

[0034] In this embodiment: By setting the support frame 701, the first screen plate 702, the second screen plate 703, the diversion plate 704, the vibration motor 705, the spring shock absorbers 706, the first blanking guide shell 707, and the second blanking guide shell 708, during use, after the construction waste is crushed, it will fall onto the first screen plate 702 through the discharge port 5. At this time, by starting the vibration motor 705, the vibration motor 705 will drive the support frame 701 to vibrate. The support frame 701 will drive the first screen plate 702 and the second screen plate 703 to vibrate. At this time, the construction waste can be preliminarily screened through the first screen plate 702. The waste with larger shell particles will stay on the first screen plate 702 and then slide down with the vibration and be discharged through the guidance of the first blanking guide shell 707. The smaller particles will pass through the first screen plate 702 and fall onto the second screen plate 703. The second screen plate 703 can perform secondary screening. Then, the smaller particles will pass through the second screen plate 703 and fall onto the diversion plate 704. The diversion plate 704 will guide the screened waste particles for discharging. Then, the waste particles staying on the second screen plate 703 will slide down with the vibration and be discharged through the guidance of the second blanking guide shell 708. Thus, the effect of multi-stage classification and screening of the crushed waste with different particle sizes can be achieved, bringing convenience to the subsequent waste treatment work.

[0035] Specifically, as Figure 1 , Figure 2 , Figure 4 shown, the number of the baffles 603 is several, and they are evenly distributed on the surface of the electric conveyor belt 602.

[0036] Specifically, as Figure 1 , Figure 2 , Figure 4 shown, support blocks 8 are fixedly connected to the four corners at the bottom of the electromagnetic separator 604, and one side of the support block 8 close to the support frame 601 is fixedly connected to the support frame 601.

[0037] In this embodiment: By arranging a plurality of baffles 603, it is possible to prevent the electric conveyor belt 602 from slipping when conveying construction waste, thereby improving the conveying stability of the electric conveyor belt 602 for construction waste. By arranging the support blocks 8, the electromagnetic separator 604 can be supported and fixed.

[0038] Specifically, as Figure 1 , Figure 3 shown, the crushing roller 3 is driven by a motor, and the crushing teeth of the two crushing rollers 3 are evenly and staggeredly distributed.

[0039] Specifically, as Figure 1 , Figure 2 , Figure 3 shown, a diversion block 9 is fixedly connected to the bottom of the inner cavity of the crushing box 2, support legs 10 are fixedly connected to the four corners at the bottom of the crushing box 2, and the bottom of the support legs 10 is fixedly connected to the moving base 1.

[0040] In this embodiment: By arranging the crushing teeth of the two crushing rollers 3 to be evenly and staggeredly distributed, the crushing effect on construction waste can be improved. By arranging the diversion block 9, the crushed construction waste can be guided for discharging. By arranging the support legs 10, the crushing box 2 can be stably supported.

[0041] Working principle: When in use, two crushing rollers 3 are driven by a motor to rotate in opposite directions simultaneously. Then, construction waste is continuously placed on the right side of the top of the electric conveyor belt 602. Then, the electric output belt is started, and the construction waste can be continuously conveyed to the feed hopper 4 through the electric conveyor belt 602, thereby reducing the labor intensity of manual feeding. And during the conveying process, the electromagnetic separator 604 can adsorb and separate metal impurities, avoiding metal waste from entering the crushing box 2 and damaging the equipment. Then, the construction waste falls into the crushing box 2 from the top of the feed hopper 4. The two crushing rollers 3 can carry out the crushing work on the construction waste. After the construction waste is crushed, it will fall on the first screen plate 702 through the discharge port 5. At this time, by starting the vibration motor 705, the vibration motor 705 will drive the support frame 701 to vibrate, and the support frame 701 will drive the first screen plate 702 and the second screen plate 703 to vibrate. At this time, the first screen plate 702 can conduct preliminary screening on the construction waste. The waste with larger shell particles will stay on the first screen plate 702 and then slide down with the vibration and be discharged under the guidance of the first blanking guide shell 707. The smaller particles will pass through the first screen plate 702 and fall on the second screen plate 703. The second screen plate 703 can conduct secondary screening. Then, the smaller particles will pass through the second screen plate 703 and fall on the diversion plate 704. The diversion plate 704 guides the screened waste particles for discharging. Then, the waste particles staying on the second screen plate 703 slide down with the vibration and are discharged under the guidance of the second blanking guide shell 708. Thus, the effect of multi-stage classification screening of the crushed waste with different particle sizes can be achieved, bringing convenience to the subsequent treatment work of the waste.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
