Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of coal dry separation, and specifically relates to a discharging device for a dry coal separator. BACKGROUND

[0002] Clean use of coal resources has become a key issue that the coal industry needs to focus on in recent years, and dry coal separation can reduce various harmful substances in coal, which is of positive significance to environmental protection. On the other hand, since the coal resources in China are mainly distributed in water resource-poor regions such as the northwest region, wet coal separation is not feasible in many cases and seriously wastes water resources. There are also many coal types such as lignite that cannot be separated by wet coal separation. Dry coal separation has developed rapidly in recent years and is conducive to resource conservation and environmental protection.

[0003] Dry coal separation technology has been widely promoted in various dimensions, especially in large-capacity raw coal separation. As a leader in dry coal separation, the applicant found that intelligent dry coal separation technology and system have broad application prospects in various open-pit mining, and are also suitable for open-pit mining. However, the clean coal discharge and collection components in the intelligent dry coal separation technology and system also have certain problems. For example, the clean coal selected by the coal separation device is discharged from the lower part of the clean coal outlet and falls into the receiving frame below. However, the clean coal is usually accumulated in the middle position of the receiving frame, which causes one receiving frame to be unable to be filled with clean coal. When the clean coal material is too high in the middle of one receiving frame, it often falls in other places, which has a certain impact on the subsequent process.

[0004] The authorized publication number "CN114132767B" describes a working method of a clean coal discharging port device for a dry intelligent coal separation system. The clean coal discharging port device includes a bottom plate and a receiving frame. The bottom plate is provided with two chutes, and the bottom of the receiving frame is fixed with four universal wheels, two of which are installed in one of the chutes, and the other two are installed in the other chute. The bottom plate is fixed with a telescopic device, which is detachably connected between the telescopic device and the receiving frame. The telescopic device includes a telescopic cylinder fixed on the bottom plate, a fixed block fixed on the piston rod of the telescopic cylinder, a limiting rod inserted through the fixed block, a limiting block corresponding to the limiting rod fixed on the receiving frame, and a limiting hole provided on the limiting block for inserting the limiting rod. The working method of the clean coal discharging port device for the dry intelligent coal separation system can ensure that the clean coal is evenly received in the receiving frame, improve the efficiency of the dry intelligent coal separation system in handling clean coal, and solve the "intestinal obstruction" problem of the prior art.

[0005] The above patent can ensure that the clean coal is evenly received in the receiving frame, thereby improving the efficiency of the dry intelligent coal preparation system in processing clean coal. However, the above patent has a single discharge structure, and only one receiving frame can be placed on one discharge to receive the material, resulting in the need to frequently replace the receiving frame, which is more troublesome, reduces work efficiency, and increases the labor intensity of the staff. Summary of the Invention

[0006] The purpose of the present invention is to: through the diversion mechanism, the material in the discharge frame is diverted out from the diversion hole on the diversion plate, and under the action of the guide plate, the material is discharged in two directions, avoiding a single discharge structure and the need to frequently replace the material frame, which is more troublesome, reduces work efficiency, and increases the labor intensity of the staff. The anti-blocking component is used to prevent the material in the discharge frame from blocking the diversion hole and affecting the discharge speed of coal and gangue. The driving component on the mounting plate drives one end of the two guide plates to rotate on the fixed axis, so that the discharge position of the coal and gangue can be adjusted, so that the coal and gangue are evenly distributed in the material receiving frame, avoiding the accumulation of coal and gangue in one position, which easily leads to the material receiving frame not being able to be filled with coal or gangue.

[0037] In the embodiment, the coal and gangue can be separated by the coal separating mechanism 2, the separating bed 201 is hung on the rack 1, and the coal and gangue can be quickly separated by cooperating with the separating component, so that the separated clean coal, medium coal and gangue enter the discharge frame 202 respectively to complete the separation. The material in the discharge frame 202 can be subjected to shunting treatment by the shunting mechanism 3. The vertical section of the shunting plate 301 is in V shape. The material in the discharge frame 202 is shunted out from the shunting holes 302 on the shunting plate 301. Under the action of the guide plates 403, the material is discharged in two directions, avoiding the single discharge structure, the frequent replacement of the receiving frame 6, the more trouble, the reduction of the working efficiency and the increase of the labor intensity of the workers. The material in the discharge frame 202 is prevented from blocking the shunting holes 302 by the anti-blocking component, so as to affect the discharging speed of the coal and gangue.

Due to the vibration force and the pressure of the material, the continuously turned material forms a spiral motion and moves to the gangue end. Because the bed surface width gradually decreases, the coal with small density is continuously stripped from the surface of the material layer and forms a plurality of products with ash content from low to high. Finally, the gangue and the impurities such as pyrite with large density are discharged from the gangue end. One end of the air pipe 207 is connected with an external fan. The fan sends air to each air chamber 206 through the air pipe 207. Under the action of the air force, the material layer can be loose, so as to facilitate the material to be layered according to the density.
