Description

Technical Field

[0001] This utility model belongs to the field of construction waste treatment technology, specifically relating to a device for removing impurities from recycled aggregates. Background Technology

[0002] Recycled aggregate refers to aggregate produced from waste concrete in construction waste through processes such as crushing and screening. Specifically, recycled aggregate is obtained by crushing, washing, and grading waste concrete blocks, and then mixing them in a certain proportion. Recycled aggregate can be divided into recycled coarse aggregate and recycled fine aggregate. Recycled coarse aggregate has a particle size greater than 4.75 mm, while recycled fine aggregate has a particle size less than or equal to 4.75 mm. Recycled aggregate is further categorized into fully recycled aggregate, recycled coarse aggregate, and recycled fine aggregate. During the production and processing of recycled aggregate, impurity removal devices are often required to clean impurities and improve the quality of recycled aggregate production. However, existing impurity removal devices for recycled aggregate have the disadvantage of poor impurity removal efficiency, failing to effectively remove particles and impurities from the recycled aggregate. This results in particles and impurities being mixed in the recycled aggregate, affecting the quality of the processed recycled aggregate, making it inconvenient to use, and reducing the efficiency and effectiveness of the impurity removal device.

[0003] Currently, most existing recycled aggregate impurity removal devices use screening to remove impurities. This means that during the impurity removal process, since the impurities in the aggregate may include low-density wood chips and plastics as well as high-density metal impurities, it is difficult to completely remove the impurities using traditional screening methods. As a result, the equipment does not perform well in removing impurities from recycled aggregates. Therefore, we propose a recycled aggregate impurity removal device. Utility Model Content

[0004] The purpose of this invention is to provide a device for removing impurities from recycled aggregates, so as to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a recycled aggregate impurity removal device, comprising a crushing box, a conveyor belt, and a water storage tank. The conveyor belt is located at the bottom of the interior of the crushing box, and a magnetic suction plate is fixedly embedded on the outer surface of the conveyor belt. A water storage tank is located on one side of the exterior of the crushing box. The conveyor belt extends through the middle of the crushing box into the interior of the water storage tank. A drive motor is located on one side of the exterior of the water storage tank, and the output shaft of the drive motor is connected to a drive roller inside the conveyor belt.

A removable metal collection trough is located at the bottom of the crushing box. An aggregate collection trough is located at the bottom of the end of the conveyor belt extending into the water storage tank. A detachable screen frame is located inside the aggregate collection trough. The water level in the water storage tank overflows the top of the aggregate collection trough.

[0006] Preferably, an electric slide rail is fixedly installed on the inner wall of the top of both sides of the water storage tank, and a moving block is provided on the outer side of each electric slide rail.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By embedding magnetic plates on the surface of the conveyor belt, metal impurities are adsorbed and distinguished for collection. In conjunction with a water storage tank, plastic and wood chip impurities with lower density are screened and made to float on the liquid surface. They are then scraped off by a scraper, thereby realizing the impurity removal process of recycled aggregate and improving the impurity removal efficiency.

[0020] Please see Figure 1-3 This utility model provides a technical solution for a recycled aggregate impurity removal device: it includes a crushing box 1, a conveyor belt 6, and a water storage tank 12. The conveyor belt 6 is installed at the bottom of the inside of the crushing box 1. A magnetic suction plate 8 is fixedly embedded on the outer circumferential surface of the conveyor belt 6. The water storage tank 12 is installed on one side of the outside of the crushing box 1. The conveyor belt 6 extends through the middle of the crushing box 1 and into the inside of the water storage tank 12. A drive motor 7 is installed on one side of the outside of the water storage tank 12. The output shaft of the drive motor 7 is connected to the drive roller inside the conveyor belt 6. A scraper 10 is installed at the bottom of one end of the conveyor belt 6 inside the crushing box 1. The scraper 10 is close to the bottom surface of the conveyor belt 6. A pull-out metal collection trough 11 is installed at the bottom of the crushing box 1. An aggregate collection trough 13 is installed at the bottom of one end of the conveyor belt 6 extending into the water storage tank 12. A detachable screen frame 14 is installed inside the aggregate collection trough 13. The water level in the water storage tank 12 overflows the top of the aggregate collection trough 13.

[0021] Specifically, electric slide rails 17 are fixedly installed on the inner walls of the top of both sides of the water storage tank 12. Moving blocks 18 are provided on the outer side of each electric slide rail 17. A scraper 19 is fixedly installed between two adjacent moving blocks 18. The bottom of the scraper 19 extends below the liquid surface.

[0022] Specifically, a discharge hole 15 is provided at the top of the end of the water storage tank 12 away from the crushing box 1, and an impurity collection trough 16 is placed at the bottom of the outer side of the discharge hole 15.

[0023] Specifically, the conveyor belt 6 is placed above one end of the crushing box 1 and a free guide plate 9 is installed. The guide plate 9 is fixedly installed on the inner wall of one side of the crushing box 1.

[0024] Specifically, crushing rollers 5 are provided on both sides of the top of the crushing box 1. A gearbox 4 is fixedly installed on one side of the outside of the crushing box 1. Two meshing gears are connected to one end of the two crushing rollers 5 respectively. A crushing motor 3 is provided on one side of the outside of the gearbox 4. A feed inlet 2 is provided on the top of the crushing box 1.

[0025] Specifically, an observation window 20 is provided on one side of the middle section of the crushing box 1, and tempered glass is fixedly embedded inside the observation window 20.

[0026] Specifically, a control panel 21 is provided on the outer side of the crushing box 1, and the control panel 21 is fixedly embedded in the outer side of the crushing box 1.

[0027] In this embodiment, during use, aggregate is introduced into the crushing box 1 through the feed inlet 2. The crushing motor 3 and gearbox 4 drive the crushing roller 5 to crush the aggregate. The crushed aggregate falls onto the conveyor belt 6. The magnetic suction plate 8 on the conveyor belt 6 attracts metal objects in the aggregate. Driven by the drive motor 7, the conveyor belt 6 transports the aggregate to above the liquid surface in the water storage tank 12. Non-metallic substances are transported from the end of the conveyor belt 6 into the water storage tank 12. Impurities with higher density than the aggregate fall into the aggregate collection tank 13 and are screened by the screen frame 14 in the aggregate collection tank 13. The process involves screening, while less dense plastic or wood chip impurities float on the water surface. The electric slide rail 17 drives the moving block 18 to move the scraper 19 to scrape off the floating impurities and discharge them into the impurity collection tank 16 through the discharge hole 15. Meanwhile, metal impurities follow the conveyor belt 6 back to the bottom of the crushing box 1 and are then hung down into the metal collection tank 11 by the scraper 10. This process removes impurities from the recycled aggregate. Through various impurity removal methods, metal, plastic, and wood chip impurities in the recycled aggregate are screened out separately, resulting in purer recycled aggregate for centralized processing.
