Description

Technical Field

[0001] This utility model relates to an air separator, and more particularly to an air separator for screening construction waste. Background Technology

[0002] With the acceleration of urbanization and the booming development of the construction industry, a large amount of construction waste has been generated. In order to achieve resource recycling and reduce environmental impact, the treatment and reuse of construction waste has gradually become a research focus. Among the many treatment methods, air separation technology has been widely used in the classification and screening of construction waste due to its simple operation, low cost, and high efficiency.

[0003] Traditional air separation technology mainly relies on fans installed on the side of the conveyor to separate lightweight materials. When construction waste passes through the conveyor belt, the airflow blown by the fans separates the less dense materials (such as plastics, wood, foam, etc.) from the heavier waste (such as concrete blocks, bricks, etc.). Although this method can achieve preliminary waste sorting to a certain extent, due to the lack of effective guidance and constraint mechanisms, when the fans start blowing air, the lightweight waste will fly around in a disorderly manner due to uneven force. This not only causes pollution to the environment around the equipment, but also, after the lightweight waste is blown away, these materials will scatter in the air due to the lack of a good collection system, increasing the complexity of subsequent collection and sorting work. Utility Model Content

[0004] In view of this, the present invention provides an air separator for screening construction waste, which can solve the problem that in the traditional air separation process, lightweight waste is easily scattered in the air after being blown out, which not only causes pollution to the environment around the equipment, but also increases the complexity of subsequent collection and sorting work.

[0005] The technical solution is as follows: A wind classifier for screening construction waste includes a support frame and an electric conveyor roller. The electric conveyor roller is rotatably arranged on the support frame at intervals for conveying construction waste. It also includes a cover frame, a fan, a limiting frame, a ventilation net, a rotating plate, a pin, and a feeding mechanism. A cover frame is provided on the top of the support frame. A fan is installed on one side of the cover frame to blow out lightweight waste from the electric conveyor roller. A limiting frame is installed on the other side of the cover frame to collect the lightweight waste blown out by the fan. A ventilation net is provided on the limiting frame for airflow. A rotating plate is rotatably arranged on the limiting frame. A pin is provided between the rotating plate and the limiting frame to limit the rotation plate. A feeding mechanism is provided on the support frame to convey construction waste onto the electric conveyor roller for feeding.

[0006] As an improvement to the above solution, a feeding mechanism is also included, which includes a feeding frame and a first conveyor. The feeding frame is installed on the side of the support frame, and the first conveyor for conveying construction waste is installed inside the feeding frame.

[0007] As an improvement to the above solution, a dust removal mechanism is also included. The dust removal mechanism includes a dust collection frame, a fan, and a collection component. The dust collection frame is installed on the top of the cover frame, and a fan is installed inside the dust collection frame. The fan is used to draw dust into the dust collection frame, and a collection component is installed inside the dust collection frame to collect the dust in the dust collection frame.

[0008] As an improvement to the above solution, a collection component is also included, which includes a sliding frame, a baffle, and a cloth bag. The sliding frame is slidably arranged inside the dust collection frame, the baffle is provided on the sliding frame, and the cloth bag for collecting dust is connected to the sliding frame.

[0009] As an improvement to the above solution, a handle is also included. The baffle is equipped with a handle for manually pulling out the baffle.

[0010] As an improvement to the above solution, it also includes a discharge hopper and a second conveyor. The discharge hopper and the second conveyor are installed on the support frame. The second conveyor is located directly below the discharge hopper. The discharge hopper is used to collect the garbage falling between the electric conveyor rollers.

[0011] The beneficial effects are as follows: 1. By setting up structures such as a cover frame, a limiting frame, and a ventilation net, this utility model ensures that lightweight waste can move along a predetermined path and be effectively collected when it is blown out by the blower. This effectively prevents lightweight waste from scattering everywhere during the air separation process, reduces pollution to the surrounding environment, provides operators with a cleaner and safer working environment, and avoids the problem of lightweight waste flying around in a disorderly manner in traditional air separation processes. This not only improves the continuity and stability of the air separation process, but also significantly enhances the accuracy and efficiency of waste sorting.

[0012] 2. By setting up a dust removal mechanism, this utility model can effectively capture the dust generated during the operation by using a combination of dust collection frame, fan and cloth bag, preventing it from escaping into the air and causing secondary pollution, thus embodying the concept of green environmental protection.

The sliding frame 1201 is slidably arranged on the right side inside the dust collection frame 10. The sliding frame 1201 is located to the left of the fan 11. The baffle 1202 is arranged on the front side of the sliding frame 1201. The cloth bag 1203 for collecting dust is connected to the right side of the sliding frame 1201.

[0024] See Figure 4 As shown, it also includes a handle 13; a handle 13 is provided on the front left side of the baffle 1202, and the handle 13 is used to manually pull out the baffle 1202.

Smaller pieces of construction waste fall through the gaps between the electric conveyor rollers 2 into the discharge hopper 14. These smaller pieces then fall through the discharge hopper 14 onto the second conveyor 15, which then discharges them. Larger pieces of construction waste continue to be conveyed to the right by the electric conveyor roller 2. When the larger pieces of construction waste pass the blower 4, the blower 4 blows the lighter waste from the larger pieces forward, allowing the lighter waste to enter... The waste is collected within the limiting frame 5, while the heavier construction waste on the electric conveyor roller 2 continues to be conveyed to the right until the electric conveyor roller 2 discharges the heavier construction waste to the right. In this way, the construction waste can be screened according to different sizes and weights, thereby realizing automatic sorting of construction waste. After all the construction waste has been sorted, the electric conveyor roller 2, fan 4, first conveyor 902, fan 11 and second conveyor 15 are turned off. Then, the pin 8 is pulled out, and the rotating plate 7 is pulled to rotate and open. Next, the light waste in the limiting frame 5 is cleaned out, and then the rotating plate 7 is pushed to reverse and close. Then, the pin 8 is put back in its original position, and the handle 13 is pulled forward, thereby driving the sliding frame 1201, baffle 1202 and bag 1203 to move forward. Then, the dust in the bag 1203 is cleaned out, and then the handle 13 is pushed back to its original position, so that the sliding frame 1201, baffle 1202 and bag 1203 move backward and reset.
