A sorting machine with an electrostatic charge removing device

Abstract

This utility model discloses a sorting machine with an antistatic device. The sorting machine is equipped with a conveyor belt and a feed inlet. The feed inlet is located at one end of the conveyor belt, and the other end of the conveyor belt is equipped with a sorting device. The end of the conveyor belt on the side of the feed inlet is equipped with a shell. A fan is installed at the air inlet of the shell, and a high-voltage electrode is installed inside the shell. The high-voltage electrode is set perpendicular to the air outlet direction of the fan, and the air outlet of the shell is directly opposite the feed inlet. The fan draws in the airflow from the rear, which first passes through the high-voltage electrode to generate positive and negative ions, generating an ionized airflow. The ionized airflow is blown toward the feed inlet at the upper end of the conveyor belt. The positive and negative ions in the ionized airflow neutralize the static electricity of the material on the conveyor belt, removing the static electricity on the material and the repulsive or attractive static ions generated by the material itself. It can also disperse stacked materials, ensuring that the materials can be stably conveyed on the conveyor belt in sequence.

Description

Technical Field

[0001] This utility model relates to the field of static electricity removal technology for sorting machines, and in particular to a sorting machine equipped with a static electricity removal device. Background Technology

[0002] Using conveyor belts to transport materials, employing detection devices to detect materials online, and utilizing time differences for online sorting is a popular existing sorting method.

[0003] However, for lightweight materials such as plastic sheets, lithium battery cell scraps, and film materials, plastic scraps are mostly made of PP or PE materials. These materials are lightweight and prone to static electricity. When the conveyor belt is moving at high speed, the materials may become statically charged. As a result, the static electricity causes the materials to be unable to be properly separated and screened during the separation process, which leads to a decrease in the accuracy of the sorting.

[0004] Therefore, existing technologies still need to be improved and enhanced. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a sorting machine with an antistatic device, which aims to solve the problem that lightweight materials are prone to generating charges during the conveying of sorting equipment, causing the materials to have an attraction effect and making it difficult to convey the materials stably.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sorting machine with an antistatic device is provided. The sorting machine is equipped with a conveyor belt and a feed inlet. The feed inlet is located at one end of the conveyor belt, and a sorting device is located at the other end of the conveyor belt. A housing is provided at the end of the conveyor belt on the side of the feed inlet. A fan is provided at the air inlet of the housing. A high-voltage electrode is provided inside the housing. The high-voltage electrode is arranged perpendicular to the air outlet direction of the fan, and the air outlet of the housing is directly opposite the feed inlet.

[0008] Furthermore, there are multiple fans and multiple high-voltage electrodes.

[0009] Furthermore, multiple high-voltage electrodes are arranged in rows along the transverse direction of the conveyor belt, and the high-voltage electrodes include positive electrodes and negative electrodes, which are arranged alternately in sequence.

[0010] Furthermore, the high-voltage electrodes are configured in two rows.

[0011] Furthermore, the outer casing is also equipped with a grille, which forms a matrix-like air duct. The grille is located on the air outlet side of the fan and adjusts the turbulent air blown out by the fan into laminar air.

[0012] The technical solution adopted in this utility model has the following beneficial effects:

[0013] In this invention, the fan draws in airflow from the rear, which first passes through a high-voltage electrode to generate positive and negative ions, producing an ionic airflow. The ionic airflow is blown toward the feed inlet at the top of the conveyor belt. The positive and negative ions in the ionic airflow neutralize the electrostatic ions on the material on the conveyor belt, removing the static electricity on the material and the electrostatic ions that repel or attract the material itself. It can also disperse stacked materials, ensuring that the materials can be transported stably on the conveyor belt in sequence. Attached Figure Description

[0017] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] A sorting machine with an antistatic device is provided. The sorting machine is equipped with a conveyor belt 6 and a feed inlet 5. The feed inlet 5 is located at one end of the conveyor belt 6, and a sorting device is located at the other end of the conveyor belt 6. A housing 1 is provided at the end of the conveyor belt 6 on the side of the feed inlet 5. A fan 2 is provided at the air inlet of the housing 1. A high voltage electrode 3 is provided inside the housing 1. The high voltage electrode 3 is arranged perpendicular to the air outlet direction of the fan 2, and the air outlet of the housing 1 is directly opposite the feed inlet 5.

[0019] In this embodiment, the fan 2 draws in airflow from the rear, which first passes through the high-voltage electrode 3 to generate positive and negative ions, producing an ionized airflow. The ionized airflow is blown toward the feed inlet 5 at the upper end of the conveyor belt 6. The positive and negative ions in the ionized airflow neutralize the electrostatic ions of the material on the conveyor belt 6, removing the static electricity on the material and the electrostatic ions that repel or attract the material itself. It can also disperse stacked materials, ensuring that the materials can be stably conveyed on the conveyor belt 6 in sequence.

[0020] In this embodiment, multiple fans 2 and multiple high-voltage electrodes 3 are provided. The multiple high-voltage electrodes 3 are arranged in rows along the transverse direction of the conveyor belt 6, and the high-voltage electrodes 3 include positive electrodes and negative electrodes. The positive electrodes and negative electrodes are arranged adjacent to each other in sequence, thereby ensuring that the air blown out by the fans 2 can carry both positive and negative ions, so as to neutralize the static ions generated by the material during the conveying process. In addition, setting the high-voltage electrodes 3 in two rows can further increase the number of positive and negative ions.

[0021] In this embodiment, the outer shell 1 is also provided with a grid 4, which is located between two rows of high-voltage electrodes 3. A matrix-like air duct is formed inside the grid 4. The grid 4 is located on the air outlet side of the fan 2 and adjusts the turbulent air blown out by the fan 2 into laminar air. After the fan 2 blows out ion wind for the first time, the ion airflow is affected by the axial fan 2 and the airflow is in a turbulent state. After being corrected by the grid 4, the airflow becomes laminar. After passing through the high-voltage electrodes 3, the number of positive and negative ions in the airflow is increased again. At this time, the generation of ion wind is completed. First, a large number of positive and negative ions are blown out. Second, the airflow is made as laminar as possible and the wind force is reduced to ensure that the falling material will not roll.

[0022] Furthermore, in the embodiments of this utility model, the specific structure of the sorting machine and sorting device is as follows: Figure 2 As shown, the details are as follows:

[0023] The sorting machine includes a feed inlet 5, a conveyor belt 6, an upper support 7, a light source 8, a hyperspectral camera 9, a sorting spray nozzle 10, a first collection trough 11, and a second collection trough 12. The upper support 7 is located at the upper end of the conveyor belt 6 and forms a material channel between the conveyor belts 6. The static eliminator and the sorting spray nozzle 10 are respectively located at both ends of the upper support 7, and the feed inlet 5 is located on one side of the static eliminator on the upper support 7. The upper support 7 is also equipped with a light source 8 and a hyperspectral camera 9 at one end of the sorting spray nozzle 10 for irradiating the material on the conveyor belt 6. The first collection trough 11 and the second collection trough 12 are located at the lower end of the conveyor belt 6, and the spray nozzle of the sorting spray nozzle 10 is directly opposite the opening of the first collection trough.

[0024] In practice, the speed of fan 2 is adjusted, and the airflow generated by fan 2 passes through a high-voltage motor, making the airflow contain positive and negative ions. After passing through the grid 4, the airflow is shaped to achieve a laminar flow state. The material to be sorted enters the sorter through the feed inlet 5 and falls into the conveyor belt 6 and the airflow. Since the airflow carries positive and negative particles, it can neutralize the static electricity on the material, so the material can move stably at high speed with the conveyor belt 6. After passing through the light source 8 and the hyperspectral camera 9, different materials have different absorption wavelengths. The computer marks the position of the material. After passing through the sorting spray nozzle 10, the material is rejected. The rejected material enters the first collection trough 11, and the other materials enter the second collection trough 12 by inertia.

[0025] As can be seen from the above embodiments, the static eliminator of this utility model can be effectively applied to sorting machines using conveyor belt 6. The airflow generated by fan 2 passes through ion electrons, making the airflow contain a high concentration of ions. When the material being conveyed by conveyor belt 6 passes through the high-concentration ion air, the surface static electricity is released, eliminating the static electricity on the surface of the material. At the same time, it also eliminates the repulsive force between materials, enabling the high-speed conveyor belt 6 to have the ability to convey lightweight materials at high speed. In addition, this static eliminator can also be used for static electricity removal in other equipment that uses conveyor belt 6 to convey materials, with high efficiency and stability.
