AI Technical Summary
[0004]本实用新型提供了一种煤基碳粉气流分选装置，解决了现有技术中不具备对物料进行多级分选的效果，导致轻重物料的混料严重、分选质量较差的技术问题
[0011]与现有技术相比，本实用新型的有益效果是：通过若干组导料板的设置可以使得落入到料箱内部的物料能够顺着每一层导料板逐渐向下滑落，当物料顺着导料板端部的倾斜向下坠落到下一层的导料板端部时，可以使得气流通过分布在导气管上喷气头向外吹出，此时物料中较小比重的颗粒就会被气流侧向吹动到通缝位置，并经过通缝落入到位于料箱两侧的分选箱中，而物料中较大比重的颗粒能够在自身的重力作用下坠落到下一层导料板上，因此物料在经过相邻两层导料板之间均能够受到气流分选的作用，通过多级分选能够提高对物料分选的效果，从而有效保证了煤炭成品的质量。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal production and processing technology, and more specifically, to a coal-based carbon powder airflow separation device. Background Technology
[0002] The coal-based carbon powder airflow separation device is a key piece of equipment that uses aerodynamic field to achieve fine separation of materials. It is mainly used in the field of deep coal processing and can classify coal-based carbon powder by particle size or density.
[0003] Existing coal-based carbon powder airflow separation devices can usually only perform single-stage separation of materials during operation, and do not have the effect of multi-stage separation. When there are many materials to be separated, it is difficult to ensure that materials of different specific gravities can be separated thoroughly, resulting in serious mixing of light and heavy materials, poor separation quality, and difficulty in ensuring the quality of finished coal products. Utility Model Content
[0004] This invention provides a coal-based carbon powder airflow separation device, which solves the technical problem that the existing technology does not have the effect of multi-stage separation of materials, resulting in serious mixing of light and heavy materials and poor separation quality.
[0005] In view of the above problems, the technical solution proposed by this utility model is as follows: A coal-based carbon powder airflow separation device includes a material box and separation boxes disposed on both sides of the material box. A feeding port is provided on one side of the top of the material box. Several sets of guide plates are arranged inside the material box. The several sets of guide plates are layered and staggered on both sides of the inner wall of the material box. The inclination direction of two adjacent sets of guide plates is opposite. A through slit is opened at the junction of the material box and the separation boxes on both sides. An air guide pipe is fixedly installed inside the material box between the ends of two adjacent sets of guide plates. Several sets of air jets facing the through slit are densely distributed on the air guide pipe. An air duct is installed on one side of the material box. A blower is installed at the end of the air duct. Each set of guide plates extends out of the outside of the material box and is connected to the air duct.
[0006] Furthermore, a dispersing roller is rotatably installed inside the feeding port, and a motor for driving the dispersing roller to rotate is installed on the side wall of the feeding port.
[0007] Furthermore, both the material bin and the sorting box are equipped with a discharge hopper at their bottom ends, and a conveyor belt is installed below both the material bin and the discharge hopper.
[0008] Furthermore, each of the two sets of sorting boxes is fixedly connected to a support rod on its side, and a base is provided at the bottom end of the support rod.
[0009] Furthermore, the tilt angle of the guide plate is between -°, and the surface of the guide plate is uniformly distributed with deceleration protrusions.
[0010] Furthermore, a control valve is installed between the end of the air duct and the blower.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up several sets of guide plates, the material falling into the material box can gradually slide down along each layer of guide plates. When the material falls down along the inclined end of the guide plate to the end of the next layer of guide plate, the airflow can be blown outward through the jet nozzles distributed on the air pipe. At this time, the particles with a smaller specific gravity in the material will be blown laterally by the airflow to the through-slit position and fall into the sorting box located on both sides of the material box through the through-slit. Meanwhile, the particles with a larger specific gravity in the material can fall to the next layer of guide plates under their own gravity. Therefore, the material can be sorted by the airflow between two adjacent layers of guide plates. Through multi-stage sorting, the sorting effect of the material can be improved, thereby effectively ensuring the quality of the finished coal product. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0017] Please see Figure 1-5 A coal-based carbon powder airflow separation device includes a material box 1 and separation boxes 2 disposed on both sides of the material box 1. A feeding port 3 is provided on one side of the top of the material box 1, through which the material to be processed is fed into the material box 1. The material box 1 is equipped with several sets of guide plates 4, which are layered and staggered on both sides of the inner wall of the material box 1, with adjacent sets of guide plates 4 inclined in opposite directions. When the material is fed into the material box 1 through the feeding port 3, it gradually slides down to the bottom along the inclined direction of each layer of guide plates 4. A through slit 5 is provided at the junction of the sorting box 2. An air guide pipe 6 is also fixedly installed inside the material box 1 between the ends of two adjacent sets of guide plates 4. Several sets of air jets 7 are densely distributed on the air guide pipe 6, and all the air jets 7 face the through slit 5. An air duct 8 is installed on one side of the material box 1. A blower 9 is installed at the end of the air duct 8. Each set of guide plates 4 extends out of the outside of the material box 1 and is connected to the air duct 8. When the blower 9 is started, it can generate a high-pressure airflow inside the air duct 8. The airflow inside the air duct 8 can be diverted to the inside of several sets of air guide pipes 6 and blown out through the air jets 7.
[0018] During operation, the materials to be sorted are fed into the material box 1 through the feeding port 3. The materials will gradually slide down each layer of guide plates 4. When the materials slide to the end of the guide plate 4, they will fall downwards along the inclination of the end of the guide plate 4 to the end of the next layer of guide plate 4. At this time, the blower 9 introduces airflow into the air duct 8. The airflow inside the air duct 8 can be divided into several sets of air guide pipes 6 connected to it, and blown outwards through the jet nozzles 7 distributed on the air guide pipes 6. When the materials fall at the end of the guide plate 4, they will be subjected to the lateral force of the airflow. At this time, the materials with a smaller specific gravity will be separated. The particles are blown laterally by the airflow to the through-slit 5 and fall into the sorting boxes 2 located on both sides of the material box 1. The particles with a larger specific gravity in the material can fall onto the next layer of guide plates 4 under their own gravity and gradually slide down to the bottom of the material box 1 along each layer of guide plates 4, thereby achieving the sorting of materials of different specific gravity and size. Since several sets of guide plates 4 are distributed alternately in the material box 1, the material can be sorted by the airflow between adjacent layers of guide plates 4. Through multi-stage sorting, the sorting effect of the material can be improved, thereby effectively ensuring the quality of the finished coal product.
[0019] For further details, please refer to Figure 3 and Figure 4 The feeding port 3 is equipped with a dispersing roller 10, and the side wall of the feeding port 3 is equipped with a motor 11 for driving the dispersing roller 10 to rotate. When the material is fed into the feeding port 3, the rotating motor 11 can disperse the material, so that the material can be dispersed evenly and avoid agglomeration, thus avoiding the impact of agglomerated material on sorting.
[0020] For further details, please refer to Figure 1 Both the material bin 1 and the sorting bin 2 are equipped with a drop hopper 12 at their bottom ends. A conveyor belt 13 is installed below both the material bin 1 and the drop hopper 12. The conveyor belt 13 is directly below the drop hopper 12. The sorted materials inside the material bin 1 and the sorting bin 2 can fall into the conveyor belt 13 through the drop hopper 12 at the bottom ends. The sorted materials are then transported separately by the conveyor belt 13, which facilitates the collection of the sorted materials.
[0021] For further details, please refer to Figure 1 and Figure 2 Both sorting boxes 2 are fixedly connected to support rods 14 on their sides. The support rods 14 can support the entire device from both sides, so that the device can maintain a certain height position with the ground. The bottom of the support rods 14 is provided with a base 15. The base 15 has a flat structure, which can ensure the stability of the device when it is in contact with the ground.
[0022] For further details, please refer to Figure 5The guide plate 4 has an inclination angle between 20-30°. The surface of the guide plate 4 is evenly distributed with deceleration protrusions 16, which allows the material to slide on the guide plate 4 at a slower speed, preventing the material from rolling directly into the sorting box 2 through the through-slit 5 due to excessive sliding speed, thus effectively ensuring the sorting effect.
[0023] For further details, please refer to Figure 2 A control valve 17 is installed between the end of the air duct 8 and the blower 9. When the blower 9 is running, the size of the airflow inside the air duct 8 can be adjusted by controlling the opening of the control valve 17, so as to adapt to the sorting requirements of different material particle sizes and improve the applicability of the device.
[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
