Technical Field

[0001] This utility model belongs to the field of screening technology and relates to a novel conveying chute screening system. Background Technology

[0002] During the transportation process, coke needs to be screened into specific sizes and coke powder according to usage requirements and transported separately. The existing transportation methods are mostly belt conveyors.

[0003] A Chinese utility model patent with publication number CN220781145U discloses a coal conveyor belt with screening function, comprising a coal conveyor belt and a filter plate. The filter plate is disposed on the top right side of the coal conveyor belt. Connecting plates are fixedly connected to both the front and rear sides of the coal conveyor belt. An installation mechanism is fixedly connected inside the connecting plate. A protective mechanism is fixedly connected to the top of the filter plate. The protective mechanism includes a vibration component and a cover component. The cover component is disposed on the vibration component. The vibration component includes two fixing plates, which are disposed on the top of two connecting plates. A cylinder is fixedly connected to the top of the fixing plate. A fixing seat is fixedly connected to the top of the cylinder. A second cover plate is fixedly connected to the side of the two fixing seats that are close to each other. The bottom of the two second cover plates is fixedly connected to the front and rear sides of the top of the filter plate. A first cover plate is fixedly connected to the left and right sides of the top of the filter plate and the left and right sides of the two second cover plates.

[0004] The existing technology has the following technical defects: Existing technologies cannot continuously screen and convey materials, and open-type power screening can easily generate a lot of dust in the workshop, affecting the workshop environment. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a new type of conveying chute screening system.

[0006] The novel conveying chute screening system of this utility model includes a conveying support, a conveying belt, an inclined flow chute and a dividing chute on the conveying support, a first powder hopper at the end of the conveying belt, and a second powder hopper corresponding to it on one side of the inclined flow chute.

[0007] An inclined screen plate is inclinedly arranged inside the inclined flow trough. The inclined screen plate has several screening holes. The space below the inclined screen plate is a powder cavity. A feed hopper is provided at the top of the inclined flow trough. A material outlet is provided on the side of the inclined flow trough facing the conveyor belt conveying direction.

[0008] The powder chamber at the bottom of the inclined flow channel is surrounded by a guide bag, and the guide bag is provided with a powder outlet corresponding to the second powder hopper.

[0009] The chute is equipped with an inverted V-shaped screen plate in the middle. The two sides of the inverted V-shaped screen plate and the outer shell of the chute form a coke discharge port. The coke discharge port is covered with a guide plate.

[0010] The inverted V-shaped screen plate has a material distribution plate in the middle.

[0011] The conveyor belt is equipped with a rotating roller, a first roller, and a second roller. The first roller and the second roller cause the conveyor belt to move in a Z-shape. The first roller is positioned above the chute so that the material can be fed into the chute along with the conveyor belt. The second roller is positioned diagonally below the inverted V-shaped screen plate so that after the conveyor belt unloads, it can pass under the inverted V-shaped screen plate and receive the material under the drive of the rotating roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a non-powered screen to screen coke into the required size, and can screen continuously without interrupting the conveying process. Compared with traditional powered screens, it can avoid the spread of dust. Attached Figure Description

[0015] Example 1 like Figures 1-4As shown, the novel conveying chute screening system of this utility model includes a conveying support, on which a conveyor belt 2, an inclined flow chute 5, and a dividing chute 3 are provided. A first powder hopper 1 is provided at the end of the conveyor belt 2, and a second powder hopper 6 is provided on one side of the inclined flow chute 5. An inclined screen plate 10 is inclinedly arranged inside the inclined flow chute 5, and a plurality of screening holes are provided on the inclined screen plate 10. The space below the inclined screen plate 10 is a powder cavity 12. A feed hopper 4 is provided at the top of the inclined flow chute 5, and the inclined flow chute 5 faces the conveying direction of the conveyor belt 2. A material outlet 13 is provided on one side. When the material enters the inclined flow trough 5, the screening holes on the inclined screen plate 10 separate larger materials and allow them to pass through, so that the coke powder falls from the screening holes into the powder chamber 12 to achieve screening. The powder chamber 12 at the bottom of the inclined flow trough 5 is surrounded by a guide bag 11. The guide bag 11 is provided with a powder outlet 14 corresponding to the second powder hopper 6. The coke powder is guided into the second powder hopper 6 through the guide bag 11 for collection, while avoiding dust dispersion in an open environment. The dividing chute 3 An inverted V-shaped screen plate 16 is provided in the center. The two sides of the inverted V-shaped screen plate 16 and the outer shell of the chute 3 form coke discharge ports 15. The coke discharge ports 15 are covered with guide plates 17. After the material enters from the top of the chute 3, it falls onto the inverted V-shaped screen plate 16. Larger materials fall from the coke discharge ports 15 on both sides and are collected, while smaller powder materials falling from the inverted V-shaped screen plate 16 fall onto the conveyor belt 2 and are sent to the first powder hopper 1 for collection. The inverted V-shaped screen plate 16 has a central section. A material distribution plate 18 is provided to divert the falling material to both sides; the conveyor belt 2 is equipped with a rotating roller 7, a first roller 8, and a second roller 9. The first roller 8 and the second roller 9 make the conveyor belt 2 move in a Z-shape. The first roller 8 is located above the chute 3, so that the material can be sent into the chute 3 along with the conveyor belt 2. The second roller 9 is located diagonally below the inverted V-shaped screen plate 16, so that after the conveyor belt 2 unloads, it can pass under the inverted V-shaped screen plate 16 and receive the material under the drive of the rotating roller 7.

[0016] This invention utilizes a non-powered screen to screen coke into the required size, and can screen continuously without interrupting the conveying process. Compared with traditional powered screens, it can avoid the spread of dust.
