[0013] This utility model has the following beneficial effects: This invention employs a combination of preferred steel, polytetrafluoroethylene (PTFE) and other polymers, or composite materials including PTFE and steel, to form a slotted plate with preferred triangular or polygonal cross-sections. The bars are staggered at certain angles to prevent wet, sticky particles from adhering or getting stuck at the slots, effectively reducing clogging and improving the efficiency of the grading and sorting machine. This invention also proposes a material separation device based on the slotted plate as the core component. Gas is used as the medium to fluidize materials such as coal fed onto the slotted plate.

Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples: In one embodiment of this utility model, such as Figure 1 , Figure 2 As shown, the strip panel structure includes a frame (1), bars (2), and reinforcing ribs (3). The frame (1) is preferably a vertical frame structure, as shown in the figure. Figure 1 (a) or planar frame structure such as Figure 1(b) The bars (2) are arranged in a staggered manner according to a certain angle pattern; the frame (1) and the reinforcing ribs (3) are provided with mounting holes (4) for fixing with other strip plates or material separation device frames.

[0016] In one embodiment of this utility model, such as Figure 2 As shown, the cross-section of the bar (2) with specific cross-sectional characteristics is preferably a polygon, the polygon including triangles. The bar (2) and the frame (1) are preferably made of steel, polytetrafluoroethylene, or a composite material including polytetrafluoroethylene and steel. The preferred angle α between the two sides of one vertex of the bar (2) is 45°-115°. The preferred structure of the frame (1) is a vertical frame structure or a planar frame structure. The bars (2) are staggered according to a certain angle pattern and are connected to the frame (1) and the reinforcing ribs (3) by plug-in connection, welding connection, or integral carving or molding to form the strip plate structure. The preferred angle β between one side of the vertex of the bar (2) and the horizontal direction is 45°-135°. The preferred angle θ between the line connecting the edges of the arranged bars (2) and the horizontal direction is 0°-45°.

[0017] In one embodiment of this utility model, such as Figure 3 As shown, a material separation device is characterized by comprising: a combined slotted plate (5), an air chamber (6), an air inlet (7), a feed port one (8-1) and a feed port two (8-2), a heavy coarse particle discharge port one (9-1) and a heavy coarse particle discharge port two (9-2), a light coarse particle discharge port (10), a frame (11), a vibration device one (12-1) and a vibration device two (12-2), a gas collection hood (13), and a fine particle and gas discharge port (14); the air chamber (6) is a single or multiple air chambers, and the air inlet (7) is arranged in the horizontal and vertical directions of the air chamber (6).

[0018] In one embodiment of this utility model, such as Figure 3 , Figure 4 As shown, the combined seam plate (5) is assembled from multiple seam plates. Each seam plate is fixed together with the adjacent seam plate and the frame (11) of the material separation device by bolts through the mounting holes (4) provided on the frame (1) and the reinforcing rib (3). The preferred angle between the installation angle of the combined seam plate (5) and the frame (11) of the material separation device and the horizontal direction is 0°-45°. The material travel direction is perpendicular to the seam.

[0019] In one embodiment of this utility model, such as Figure 3As shown, the preferred angle δ between the center line connecting the two sets of excitation devices 1 (12-1) and 2 (12-2) and the horizontal direction is 0°-60°. The rotation directions of the two sets of excitation devices 1 (12-1) and 2 (12-2) are opposite. The preferred angle between the direction of the excitation force generated by the two sets of excitation devices and the horizontal direction is 90°-150°. When the preferred angle between the direction of the excitation force generated by the two sets of excitation devices 1 (12-1) and 2 (12-2) and the horizontal direction is 90°, the material is fed into the combined slotted plate (5) through the feed inlet 1 (8-1). Under the combined action of the airflow that enters the air chamber (6) through the air inlet (7) and passes through the combined slotted plate (5), the excitation force generated by the excitation device, and gravity, the material is stratified and separated according to its weight, and the heavy and coarse particles are transported separately. The heavy and coarse particles are discharged from the discharge port (9-1), while the light and coarse particles are discharged from the discharge port (10). At the same time, the airflow blows out the fine particles, and the exhaust air collected by the gas collecting hood (13) is discharged from the discharge port (14). This can separate the material by weight and size, and the separation ratio of heavy and light particles and the separation particle size can be adjusted by adjusting the airflow. When only separation by particle size is required, The heavy coarse particle outlet 1 (9-1) and the light coarse particle outlet (10) can be combined, and the coarse heavy particles and coarse light particles are combined into coarse particles and discharged from the heavy coarse particle outlet 1 (9-1); when the direction of the excitation force generated by the excitation device 1 (12-1) and the excitation device 2 (12-2) is inclined at a preferred angle of 90°-150° to the horizontal direction towards the outlet 2 (9-2), the material is fed into the combined slotted plate (5) from the feed inlet 2 (8-2). Under the combined action of airflow entering the air chamber (6) through the air inlet (7) and passing through the combined slotted plate (5), the excitation force generated by the excitation device, and gravity, the material is separated into light and heavy layers. The heavy particles sink to the bottom layer and are conveyed forward along the combined slotted plate (5) and discharged from the second heavy coarse particle outlet (9-2). The light particles float on the top layer and slide downwards and are discharged from the light coarse particle outlet (10) (at this time, the first heavy coarse particle outlet (9-1) and the light coarse particle outlet (10) are merged). At the same time, the airflow blows out the fine particles, which are discharged from the fine particles and gas outlet (14) by the exhaust air collected by the gas collecting hood (13). This can separate the material into light and heavy particles as well as into large and small particles. Moreover, the separation ratio of light and heavy particles and the separation particle size of large and small particles can be adjusted by adjusting the airflow size. The air chamber is a multi-chamber structure, and the air inlet can be in the horizontal or vertical direction or a combination of horizontal and vertical directions.

[0020] In one embodiment of this utility model, the material separation device can be installed on a vehicle, a mobile platform, or work underground.

[0021] The embodiments of this utility model have been described in detail above, but the content described should not be construed as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of this utility model application should still fall within the patent coverage of this utility model.
