[0002] The coal used in thermal power units is affected by market factors, and there is great uncertainty in the source and transportation. Regardless of whether the coal is transported into the factory by rail, water or road, there is adulteration. The debris includes woven bags, steel wire ropes, cotton ropes, stones, etc. These debris will not only affect the combustion efficiency, but also cause the belt conveyor to malfunction when it is transported by belt conveyor after entering the factory.

[0003] In order to remove impurities from the burning coal, a new type of simple impurity removal device for the coal conveying system is needed.

[0004] However, the current conventional impurity removal system can usually remove some large stones or other debris, but there are still some smaller stones and debris in the coal, which can easily cause belt scratches, roller jams, coal drop pipe blockages and other phenomena affecting normal operation during the belt conveyor transportation process. If you want to finely screen and select the coal, you need to use more sophisticated screening instruments, which increases the steps and procedures of the coal transportation system and is more expensive. Therefore, it is necessary to use a new type of simple impurity removal device for the coal transportation system as a supplement to the conventional impurity remover to remove the impurities in the belt conveyor.

A cleaning V-shaped plate 6 is fixedly connected to the right side of the screening V-shaped plate 5. The screening V-shaped plate 5 has a V-shape that is wider on the left and narrower on the right. When the coal contacts the left inclined surface of the screening V-shaped plate 5, it will move along the inclined surface toward the center of the screening V-shaped plate 5. When the impurities contact the inclined surface on the left side of the impurity removing V-shaped plate 6, it will move along the inclined surface toward both sides of the impurity removing V-shaped plate 6. The top of the impurity removing V-shaped plate 6 is fixedly connected to the bottom of the support plate 3. The bottom ends of the screening V-shaped plate 5 and the cleaning V-shaped plate 6 are provided with through openings 7 for convenient passage of coal. The area of ​​the right side of the separation triangle 4 is larger than the area of ​​the through opening 7, so that the coal and impurities passing through the separation triangle 4 will not directly enter the through opening 7.

[0032] Reference Figure 3-Figure 4 The bottom of the screening V-shaped plate 5 is provided with a screening port 8 for separating small stones and coal. The screening port 8 is set small, and larger coal blocks cannot pass through the screening port 8. The inner wall of the side of the screening port 8 is provided with a rotating circular groove 9. The rotating circular groove 9 is provided with two groups, which are symmetrically arranged on the front and rear sides of the screening port 8. A damping component for preventing lighter objects from passing through is fixedly connected inside the rotating circular groove 9. The damping component includes a volute spring 10. The outer end of the volute spring 10 is fixedly connected to the inner wall of the side of the rotating circular groove 9, and the inner end of the volute spring 10 is fixedly connected At the periphery of the rotating column 11, when the rotating column 11 is not subjected to force, the spiral spring 10 will drive the rotating column 11 to rotate clockwise, and the outer periphery of the rotating column 11 is rotatably connected to the inside of the rotating circular groove 9, and a screening door 12 is fixedly connected to the outer periphery of the damping assembly.

Under the support of the damping assembly, the screening door 12 will not be pushed open by the lighter coal blocks, but will be pushed open by the heavier small stones, allowing them to pass.

[0033] Reference Figure 1-Figure 2A collecting groove 13 is provided at the top of the support plate 3. The collecting groove 13 can collect light debris, such as small woven bag fragments or cotton ropes, etc. A through groove 14 is provided on the left side of the collecting groove 13.

Four groups of de-mudifier hooks 19 are arranged, which are linearly and evenly distributed on the outer periphery of the rotating shaft 18. The position of each group of de-mudifier hooks 19 is opposite to the position of a group of passing grooves 14, so as to facilitate the de-mudifier hooks 19 to pass through the collecting groove 13. Four de-mudifier hooks 19 are arranged in each group, and the four de-mudifier hooks 19 are evenly distributed in a ring shape on the outer periphery of the rotating shaft 18.

[0034] Working principle: When you want to easily remove smaller stones on the belt conveyor, turn on the belt conveyor, and the top belt of the belt conveyor will transport the coal to the right. When the coal passes through the separation triangle 4, it is separated to both sides by the separation triangle 4 and then continues to be transported. When it is transported to the screening V-shaped plate 5, the larger pieces of coal will move to the center along the inclined surface of the screening V-shaped plate 5 and be transmitted through the through port 7. The smaller coal and small stones will slide along the inclined surface of the screening V-shaped plate 5. When they hit the screening door 12, the small stones with larger density and heavier mass will push the screening door 12 open and enter the screening port 8. The coal blocks with smaller density and lighter mass will not be able to push the screening door 12 open under the action of the force of the damping component, so that they can only move along the inclined surface to the center of the screening V-shaped plate 5, pass through the through port 7, and the small stones entering the screening port 8 will continue to move to the right and touch the impurity removal V-shaped plate 6. Under the squeezing of the left inclined surface of the impurity removal V-shaped plate 6, they will move to both sides and leave the belt conveyor, thereby removing the small stones. When light debris on the belt conveyor is to be removed, the rotating motor 16 is turned on, and the output shaft of the rotating motor 16 drives the rotating shaft 18 to rotate, and the rotating shaft 18 drives the debris removal hook 19 to rotate. When the debris removal hook 19 rotates to the bottom, it will hook up debris such as woven bag fragments or cotton ropes in the coal. When the debris removal hook 19 rotates to the top, the debris falls under the action of gravity and enters the inside of the collecting tank 13, thereby removing the light debris.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
