Description

Technical Field

[0001] This utility model relates to the field of air classifier technology, specifically to an air classifier material handling device. Background Technology

[0002] While modern science and technology continue to advance, the development of technologies for the treatment and reuse of municipal solid waste lags behind. This not only hinders the development of environmentally friendly cities but has also become a primary issue in improving people's living environment. Currently, municipal solid waste is mainly treated through landfill and incineration. Landfilling not only occupies a large area of ​​land but also pollutes groundwater, and plastics buried underground cannot degrade for a long time. While incineration significantly reduces the volume of waste, it is costly and, during incineration, plastics in the waste produce harmful gases, leading to air pollution.

[0003] In response to the above phenomena, waste sorting and resource utilization has become an effective way to reduce waste. Through waste sorting, the materials in waste can be utilized as resources, which can effectively reduce the pressure of waste on the environment. In the waste sorting system, the air separator is one of the most important waste sorting machines. Air separation is an ancient screening method that can separate lighter waste from heavier waste. However, during the sorting process, it is found that some lighter waste is mixed with heavier waste, which makes sorting difficult. Therefore, this technical solution is proposed to improve the process. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing air separators in separating waste of different qualities, and to provide an air separator material handling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a material sorting device for an air classifier, comprising a feeding conveyor belt disposed at the feeding end, an air inlet duct connected to a fan disposed below the feeding conveyor belt, an air outlet of the air inlet duct facing the conveying direction of the feeding conveyor belt, a material sorting plate disposed above the feeding conveyor belt, an adjustment device for controlling the height disposed at the tail of the material sorting plate, and an adjustment plate disposed at the tail of the material sorting plate.

[0006] Furthermore, the adjusting device includes a horizontally arranged support rod, an adjusting rod is provided at the middle position of the support rod, the adjusting rod passes through the support rod and is hinged to the material handling plate below, and an adjusting handwheel is provided at the upper part of the adjusting rod.

[0007] Furthermore, the material handling plate is L-shaped, and the tail of the material handling plate is set to be inclined upward.

[0008] Furthermore, a rotating shaft is provided at the tail of the feeding plate, and the output direction of the adjusting plate is inclined downward.

[0009] Furthermore, a separating roller is provided below the adjusting plate, the separating roller is connected to a drive motor, the separating roller is located behind the feeding conveyor belt, and the axis of the separating roller is lower than the feeding conveyor belt.

[0010] Furthermore, a discharge conveyor belt is provided below the separating roller.

[0011] The beneficial effects of this utility model embodiment are as follows: An air inlet is provided below the feeding conveyor belt, and the air outlet faces the conveying direction of the feeding conveyor belt. Furthermore, the air outlet's direction is inclined upwards. After the garbage on the feeding conveyor belt is lifted, the air blown out by the air inlet blows the lighter garbage upwards, while the heavier garbage is blown a shorter distance and falls downwards. By adjusting the fan's power, the airflow's force on the garbage can be controlled, achieving preliminary air separation. Above the feeding conveyor belt, a material handling plate is installed, and a support rod is installed in the middle position. The device features an adjustable rod that passes through a support rod and hinges to the sorting plate below. This allows for flexible adjustment of the sorting plate's angle as needed. An adjustable handwheel is mounted on the upper part of the rod, enabling operators to easily adjust the height and tilt angle of the sorting plate to accommodate different types and volumes of waste. Adjusting the sorting plate's angle also changes the angle of the sorting plate itself. The adjustable plate further optimizes the waste flow path, improves sorting purity, and is easy to operate, maintain, and upgrade, ultimately enhancing the accuracy and efficiency of waste sorting.

[0016] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0017] See Figures 1 to 3 This utility model discloses an air separation machine material handling device, which mainly includes a feeding conveyor belt 3, an air inlet duct 101, a blower 1, a material handling plate 201, an adjustment device, etc. A feeding conveyor belt 3 is provided on the left side for continuously feeding the domestic waste to be sorted into the air separation area. An air inlet duct 101 is provided below the feeding conveyor belt 3. The air inlet duct 101 is connected to the blower 1, and its air outlet is directly facing the conveying direction of the feeding conveyor belt 3. Moreover, the air outlet is inclined upward. After the waste on the feeding conveyor belt 3 is lifted, the air blown out by the air inlet duct 101 blows the light waste upward. The heavier waste is blown a shorter distance and can only fall downward. By adjusting the wind force of the blower 1, the force of the airflow on the waste can be controlled to achieve preliminary air separation.

[0018] Above the feeding conveyor belt 3, a sorting plate 201 is installed. Its function is to further sort and disperse the waste to facilitate the effective action of the wind. The tail of the sorting plate 201 is designed with an adjustment device, which includes a horizontally arranged support rod 203. An adjustable rod 204 is installed in the middle of the support rod 203. The adjustable rod 204 passes through the support rod 203 and is hinged to the sorting plate 201 below, so that the angle of the sorting plate 201 can be flexibly adjusted as needed. An adjusting handwheel 205 is installed on the upper part of the adjusting rod 204. The operator can easily adjust the height and tilt angle of the sorting plate 201 by rotating the handwheel 205 to adapt to the needs of different types and volumes of waste processing. This helps to guide the light waste that has been initially separated by the wind to slide down in a specific direction, reducing the mixing with heavy waste. To facilitate adjustment, the material feeding plate 201 is designed as an L-shaped plate, with its tail hinged to the adjusting rod 204. This increases the adjustment angle of the material feeding plate 201 and improves the adjustment effect. A pivot is also designed at the tail of the material feeding plate 201, which provides support when adjusting the angle of the material feeding plate 201, ensuring optimal performance. An adjusting plate 202 is also located at the tail of the material feeding plate 201, fixedly mounted to it. When the angle of the material feeding plate 201 is adjusted, the angle of the adjusting plate 202 also changes accordingly. The presence of the adjusting plate 202... The flow path of the waste has been further optimized, improving the purity of the sorting. The output direction of the adjusting plate 202 is tilted downward, which facilitates the guidance of the separated light waste to the next processing stage. Below the adjusting plate 202, a set of separating rollers 5 is added. The separating rollers 5 are driven by a drive motor to rotate. Their axis is lower than the feeding conveyor belt 3, which can ensure that the waste sliding off the sorting plate 201 can be further sorted and separated by the rotation of the rollers when it comes into contact with the separating rollers 5. In particular, it can effectively achieve physical separation of light impurities that are still attached to heavy waste, ensuring the effect of use.

[0019] A discharge conveyor belt 4 is configured below the separating roller 5 to collect and transport the waste that has undergone air separation and physical sorting. A buffer shell 2 is set on the outside of the discharge conveyor belt 4 to wrap the front of the discharge conveyor belt 4, reducing dust spillage and restricting the movement path of lightweight waste. The design of the discharge conveyor belt 4 not only facilitates the subsequent processing of waste, but also ensures the continuity and automation level of the entire air separation process. The material sorting plate 201 has a simple structure, is easy to operate, and is easy to maintain and upgrade, thus improving the accuracy and efficiency of waste sorting.
