Description

Technical Field

[0001] This utility model relates to the technical field of raw coal washing and waste disposal equipment for coking coal, and in particular to a raw coal washing and waste disposal equipment for coking coal production. Background Technology

[0002] For example, CN221714874U describes a coal preparation and gangue removal device that uses sorting channels of different sizes to separate coal and gangue into equal sizes before throwing them out for screening. Compared with the traditional water washing method, it has a better environmental protection effect. However, when irregular materials pass through its sorting channels, which are similar to screening screens, material jamming is inevitable, which reduces the sorting efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a raw coal washing and gangue removal device for coking coal production to address the aforementioned technical problems of easy material jamming and low sorting efficiency.

[0004] To achieve the above objectives, this utility model provides a raw coal washing and gangue removal device for coking coal production, including a frame. The frame is hinged to an inclined feeding plate. The upper surface of the feeding plate is provided with a V-shaped groove that is low in the center and high on both sides. Several V-shaped guide plates are installed inside the frame. The distance between the V-shaped guide plates and the V-shaped grooves decreases continuously as the material conveying distance of the feeding plate increases. The distance from the bottom of each V-shaped guide plate to the surface of the V-shaped groove is the same. The bending point of the V-shaped guide plate is closest to the feed inlet on the frame. The two forked ends of the V-shaped guide plate are located on both sides of the feeding plate. Guide grooves are installed on both sides of the frame.

[0005] Preferably, the tilt angle of the feeding plate is 10°~25°.

[0006] Preferably, the side of the V-shaped guide plate that contacts the material has a chamfer.

[0007] Preferably, the bottom chamfer of the V-shaped guide plate is provided with several buffer grooves, a movable block is slidably engaged in the buffer groove, a rotating component is rotatably mounted on the movable block, an elastic component is installed in the buffer groove, and the output end of the elastic component is connected to the movable block.

[0008] Preferably, a plurality of screening conveyors are installed on the frame, the screening conveyors are located below the output end of the guide chute and below the output end of the feeding plate, and a plurality of holding frames are placed on the frame, the holding frames being located below the output end of the screening conveyors.

[0009] Preferably, a slow-moving cotton pad is installed inside the feed trough.

[0010] Compared with existing technologies, this technical solution has at least one of the following beneficial effects: 1. By setting different spacings between several V-shaped guide plates and feeding plates, materials of different sizes are classified and then pushed to both sides for output. Compared with the screen-type falling screening, this avoids the problem of material jamming and makes the sorting efficiency higher. 2. By designing rotating components, materials are less likely to break during vibration sorting and guided output, reducing dust generation and further improving environmental protection.

Detailed Implementation

[0012] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] Please see Figures 1 to 4 This application provides a raw coal washing and gangue removal device for coking coal production, including a frame 1. The frame 1 is hinged to an inclined feeding plate 2. One end of the feeding plate 2 is hinged to the discharge port and installed on the frame 1. The other end of the feeding plate 2 is connected to the frame 1 through a vibration motor, damping spring, etc. The upper surface of the feeding plate 2 is provided with a V-shaped groove 3 that is low in the center and high on both sides. Several V-shaped guide plates 4 are fixedly installed inside the frame 1. The distance between the several V-shaped guide plates 4 and the V-shaped groove 3 decreases continuously as the material conveying distance of the feeding plate 2 increases. The distance from the bottom of the V-shaped guide plate 4 to the surface of the V-shaped groove 3 is the same. The bending point of the V-shaped guide plate 4 is closest to the feeding port on the frame 1. The two forked ends of the V-shaped guide plate 4 are located on both sides of the feeding plate 2 and are in clearance fit with the frame 1 with a small gap. Guide grooves 5 are fixedly installed on both sides of the frame 1.

[0014] In this embodiment, when the material falls from the feed inlet on the frame 1 onto the feeding plate 2, it is conveyed downwards by the vibration of the inclined feeding plate 2. During conveying, large pieces of material will first come into contact with the V-shaped guide plate 4 and gradually move outwards along the feeding plate 2 during the vibration conveying, eventually falling into the guide trough 5 for conveying. Smaller pieces of material can pass through the gap between the first V-shaped guide plate 4 and the feeding plate 2 and be further screened by subsequent V-shaped guide plates 4. The setting of the V-shaped trough 3 makes it easier for the remaining small pieces of material to gather towards the center when the V-shaped guide plate 4 guides the material outwards, preventing them from being pushed out along with the large pieces of material. The distance between the V-shaped guide plate 4 and the V-shaped trough 3 is the same at all points, so that the material being limited and guided can always be limited. When the feeding plate 2 vibrates, it is inevitable that some corners of the material will collide with the V-shaped guide plate 4 and fall off as fragments. However, since the material does not rotate after coming into contact with the V-shaped guide plate 4, only one corner of the material is squeezed off and falls within an acceptable range.

[0015] In some embodiments, to facilitate the material sliding down the vibrating feeder 2, the tilt angle of the feeder 2 is set to 10°~25°. This is a preferred angle; if the angle is too small, the conveying and sliding efficiency will be low, and if the angle is too large, large pieces of material will slide at a faster speed, easily pushing small pieces of material down with them.

[0016] In some embodiments, to further prevent the material from being crushed by the feed plate 2 and the V-shaped guide plate 4, a chamfer is provided on the side of the V-shaped guide plate 4 that contacts the material. Therefore, the material will only be crushed when the protrusion is too large; otherwise, it will not be easily crushed because it only contacts the chamfer and not the lowest point of the V-shaped guide plate 4.

[0017] In some embodiments, to further prevent material breakage, a plurality of buffer grooves 6 are provided at the chamfered bottom of the V-shaped guide plate 4. A movable block 7 is slidably engaged in the buffer groove 6, and a rotating component 8 is rotatably mounted on the movable block 7. The rotating component 8 may be a universal ball. An elastic component 9, which may be a spring, is fixedly installed in the buffer groove 6, and the output end of the elastic component 9 is connected to the movable block 7. When the material impacts the V-shaped guide plate 4, it can first collide with the rotating component 8, thereby squeezing the movable block 7 to slide inward in the buffer groove 6, reducing the impact force of the material on the V-shaped guide plate 4 and making the material less prone to breakage. Afterward, the elastic component 9 can drive the movable block 7 to reset. The function of the rotating component 8 is only to facilitate the material to slide along the surface of the V-shaped guide plate 4, so even if it is difficult to rotate in the presence of high dust, it will not cause a significant impact.

[0018] In some embodiments, to facilitate the ejection and screening of sorted materials, a plurality of screening conveyors 10 are installed on the frame 1. The screening conveyors 10 can be belt conveyors as in the prior art. The screening conveyors 10 are located below the output end of the guide chute 5 and below the output end of the feeding plate 2. A plurality of holding frames 11 are placed on the frame 1, and the holding frames 11 are located below the output end of the screening conveyors 10. After the materials are conveyed by the guide chute 5 and fall onto the surface of the screening conveyors 10, they can be carried out by them and fall into different holding frames 11 according to their different weights for separate collection.

[0019] In some embodiments, a deceleration pad 12 is fixedly installed inside the guide chute 5 to facilitate deceleration of the material. The deceleration pad 12 may be adhered to the inner wall of the guide chute 5, so that it will not completely fall off even if the tip of the material scratches the deceleration pad 12.

[0020] The fixed connection and rotating installation in the above embodiments can all be achieved by welding, screw fasteners and other forms in the prior art, and the rotating installation can be achieved by bearings, circular rotating blocks and circular grooves. All of the above components are standard parts, and those that are not standard parts can also be specially customized, so the inventor will not elaborate further.

[0021] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
