Description

Technical Field

[0001] This utility model relates to the technical field of construction waste treatment equipment, and in particular to a construction waste recycling and regeneration treatment device. Background Technology

[0002] The booming development of the construction industry has generated a large amount of construction waste. If this waste is not properly treated, it will not only occupy a lot of land resources but also cause serious environmental pollution. Therefore, the recycling of construction waste has become an important issue for the industry's development. Construction waste is usually processed by crushing equipment to facilitate subsequent reuse.

[0003] In the crushing process, in order to ensure the crushing effect, the crushed waste needs to be screened through a screen to separate the waste that has not been crushed sufficiently. However, after the existing processing equipment screens out the waste that has not been crushed sufficiently, it often needs to be manually put back into the crushing mechanism for secondary crushing. This manual operation not only increases the labor intensity of the workers, but also has low efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the following shortcomings in the existing technology: after screening out the waste that has not been sufficiently crushed, the existing processing devices often require manual re-feeding into the crushing mechanism for secondary crushing. This manual operation not only increases the labor intensity of the workers, but also has low efficiency. Therefore, this utility model proposes a construction waste recycling and processing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A construction waste recycling and processing device includes a base, on which a screen is inclinedly mounted via a support assembly, and a bracket is fixedly mounted on the base. A crushing mechanism is fixedly mounted at one end of the bracket, and the crushing mechanism is located directly above the screen. A feed hopper is mounted on the crushing mechanism. The base is vertically fixed with a feeding cylinder, and a first guide plate is inclinedly fixed on the base. One end of the first guide plate is located directly below the screen. The feeding cylinder has a feed inlet on its side, and the other end of the first guide plate is connected to the feed inlet. The feeding cylinder has a discharge outlet on its side, and a second guide plate is inclinedly fixed on the feeding cylinder. One end of the second guide plate is connected to the discharge outlet, and the other end is located directly above the feed hopper. A rotating shaft is vertically and rotatably installed inside the feeding cylinder. An auger blade is fixedly sleeved on the rotating shaft. The auger blade is rotatably installed inside the feeding cylinder. A drive motor is fixedly installed at the upper end of the feeding cylinder. The output end of the drive motor is fixedly connected to one end of the rotating shaft.

[0006] Preferably, the support assembly includes two support rods symmetrically fixedly mounted on the base, two sliders respectively horizontally slidably mounted on the two support rods, and two connecting blocks respectively fixedly mounted on the two sliders. Each of the two support rods has a sliding hole in the horizontal direction, the sliders are horizontally slidably mounted in the sliding holes, and the screen is fixedly mounted on the two connecting blocks in an inclined state.

[0007] Preferably, a fixing frame is fixedly installed on the two support rods, and a reciprocating cylinder is fixedly installed on the fixing frame. The output end of the reciprocating cylinder is fixedly connected to the side of the screen.

[0008] Preferably, a collection box is placed on the base, and the collection box is located directly below the screen.

[0009] Preferably, a U-shaped baffle is fixedly installed on the upper surface of the screen, and the two ends of the U-shaped baffle are close to the first guide plate.

[0010] Preferably, the first guide plate is inclined toward the feed inlet, and the second guide plate is inclined toward the feed hopper.

[0011] The beneficial effects of this utility model are as follows: 1. The insufficiently crushed waste screened out by the screen can enter the feeding cylinder under the guidance of the first guide plate. The drive motor drives the rotating shaft and auger blades to rotate, which can transport the waste upward along the feeding cylinder. Then, it is accurately guided into the feed hopper of the crushing mechanism through the second guide plate to complete the secondary crushing. No manual intervention is required, which reduces the labor burden of the staff. The automated return process avoids the inefficiency caused by manual operation, so that the crushing, screening and re-crushing process of construction waste can be carried out continuously and efficiently, shortening the overall processing cycle and improving the processing efficiency of the device. 2. The reciprocating cylinder in the support assembly can drive the screen to slide horizontally back and forth on the support rod via the slider, which enhances the vibration effect of the screen and can more quickly and thoroughly separate the insufficiently crushed waste from the qualified crushed material, reducing screening omissions.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-2 A construction waste recycling and processing device includes a base 1, which serves as the basic support component of the entire device, providing an installation platform for other structures and ensuring the overall stability of the device. A screen 2 is installed at an angle on the base 1 via a support component. The angled screen 2 facilitates the natural sliding of waste during the screening process using gravity, improving screening efficiency. A bracket 3 is fixedly installed on the base 1, and a crushing mechanism 4 is fixedly installed at one end of the bracket 3. The bracket 3 stably supports the crushing mechanism 4 at a specific height and position. The crushing mechanism 4 is positioned directly above the screen 2, allowing the crushed waste to fall directly onto the screen 2 for screening, reducing waste transfer links and improving process continuity. A feed hopper 5 is installed on the crushing mechanism 4, which receives the construction waste to be crushed. Its large opening design facilitates the input of waste by workers or automatic feeding equipment, while guiding the waste accurately into the crushing mechanism 4.

[0016] Reference Figure 3 A feeding cylinder 6 is vertically fixed on the base 1. A first guide plate 7 is inclinedly fixed on the base 1. One end of the first guide plate 7 is located directly below the screen 2. A feed inlet is opened on the side of the feeding cylinder 6. The other end of the first guide plate 7 is connected to the feed inlet. A discharge outlet is opened on the side of the feeding cylinder 6. A second guide plate 8 is inclinedly fixed on the feeding cylinder 6. One end of the second guide plate 8 is connected to the discharge outlet, and the other end is located directly above the feed hopper 5.

[0017] The feeding cylinder 6 provides a closed channel for conveying waste, preventing waste from spilling during the conveying process. The first guide plate 7 is used to receive the insufficiently crushed waste screened by the screen 2. The insufficiently crushed waste can slide into the feeding cylinder 6 under its own gravity under the guidance of the first guide plate 7. The function of the second guide plate 8 is to guide the insufficiently crushed waste conveyed by the feeding cylinder 6 into the feed hopper 5, so as to realize the recycling and crushing of waste.

[0018] A rotating shaft 9 is vertically and rotatably installed inside the feeding cylinder 6. An auger blade 10 is fixedly sleeved on the rotating shaft 9. The auger blade 10 is rotatably installed inside the feeding cylinder 6. A drive motor 11 is fixedly installed at the upper end of the feeding cylinder 6. The output end of the drive motor 11 is fixedly connected to one end of the rotating shaft 9. The drive motor 11 provides power to the entire feeding system. When it is working, it drives the rotating shaft 9 to rotate. The rotating shaft 9 then drives the auger blade 10 to rotate inside the feeding cylinder 6. During the rotation of the auger blade 10, it pushes the waste inside the feeding cylinder 6 upward and finally discharges it from the outlet, completing the lifting and conveying of the waste.

[0019] Reference Figures 4-5 The support assembly includes two symmetrically fixed support rods 12 mounted on the base 1, two sliders 13 respectively horizontally slidably mounted on the two support rods 12, and two connecting blocks 14 respectively fixedly mounted on the two sliders 13. The two support rods 12 are the main load-bearing components of the support assembly. Their fixed mounting on the base 1 ensures the stability of the support. Both support rods 12 have sliding holes in the horizontal direction. The sliders 13 are horizontally slidably mounted in the sliding holes. The sliding holes provide trajectory constraints for the horizontal sliding of the sliders 13, so that the sliders 13 can only move along the direction of the sliding holes. The screen 2 is fixedly mounted on the two connecting blocks 14 in an inclined state. The connecting blocks 14 connect the sliders 13 and the screen 2 into one unit, so that the sliding of the sliders 13 can drive the screen 2 to move synchronously.

[0020] A fixed frame 15 is fixedly installed on the two support rods 12. The fixed frame 15 provides a mounting carrier for the reciprocating cylinder 16, enabling it to act stably on the screen 2. The reciprocating cylinder 16 is fixedly installed on the fixed frame 15. The output end of the reciprocating cylinder 16 is fixedly connected to the side of the screen 2. When the reciprocating cylinder 16 is working, its output end will make a reciprocating linear motion, which will drive the screen 2 to slide horizontally back and forth in the sliding hole of the support rod 12 through the slider 13. This reciprocating motion enhances the screening effect of the screen 2 and can more effectively separate the waste that is not fully crushed.

[0021] A collection box 17 is placed on the base 1. The collection box 17 is located directly below the screen 2. Its function is to collect the waste that meets the crushing requirements after being screened by the screen 2, so as to facilitate the unified treatment and reuse of these qualified wastes in the future.

[0022] A U-shaped baffle 18 is fixedly installed on the upper surface of the screen 2. The two ends of the U-shaped baffle 18 are close to the first guide plate 7. The U-shaped baffle 18 can prevent waste from sliding on the screen 2 and falling from the side of the screen 2 during the screening process, ensuring that all the waste that is not fully crushed can flow to the first guide plate 7, thereby improving the recycling rate of waste and the accuracy of screening.

[0023] The first guide plate 7 is tilted towards the feed inlet. This tilted design allows the waste to slide smoothly from below the screen 2 into the feed inlet of the feeding cylinder 6 under the action of gravity. The second guide plate 8 is tilted towards the feed hopper 5. Similarly, the tilt angle allows the waste to slide from the discharge port of the feeding cylinder 6 into the feed hopper 5, reducing the retention of waste during the guiding process.

[0024] In this invention, construction waste is first fed into the crushing mechanism 4 through the feed hopper 5. The crushing mechanism 4 crushes the waste, and the crushed waste falls onto the inclined screen 2 below. At this time, the reciprocating cylinder 16 operates, driving the screen 2 to slide horizontally back and forth on the support rod 12 via the slider 13, screening the waste. Waste that meets the crushing requirements falls into the collection box 17 below through the mesh of the screen 2, while waste that is not fully crushed slides along the screen 2 onto the first guide plate 7 under the action of the reciprocating motion of the screen 2 and its own gravity.

[0025] Incompletely crushed waste is guided into the feed inlet of the feeding cylinder 6 by the first guide plate 7. The drive motor 11 starts, driving the rotating shaft 9 and the auger blades 10 to rotate. The auger blades 10 push the waste upward along the feeding cylinder 6 until it is discharged from the outlet onto the second guide plate 8. Finally, it is guided by the second guide plate 8 into the feed hopper 5 and re-enters the crushing mechanism 4 for secondary crushing. This cycle is repeated to achieve efficient recycling of construction waste without manual intervention, reducing the workload of workers. The automated return process avoids the inefficiency caused by manual operation, enabling the crushing, screening, and re-crushing of construction waste to be carried out continuously and efficiently, shortening the overall processing cycle and improving the processing efficiency of the device.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
