Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for conveying scraper conveyors in refined coal silos, and specifically relates to a high-efficiency guide rail for scraper conveyors in refined coal silos. Background Technology

[0002] In the production operations of the clean coal bins in coal washing plants, the scraper conveyor is the core equipment for conveying clean coal, and the slide rail, as an important support and running component of the scraper conveyor, directly affects the operating efficiency and safety of the scraper conveyor. Currently, most scraper conveyors in coal washing plants use a slide rail structure composed of channel steel and column base, which has obvious defects: 1. Insufficient flatness of the channel steel surface can easily cause the scraper to get stuck during operation, leading to frequent scraper failures. At the same time, the channel steel has poor wear resistance and a short service life, requiring frequent replacement of parts. 2. The coal drop point is not equipped with a dedicated material guiding structure, and the coal is prone to deviating from the center of the scraper and directly impacting the scraper chain, causing chain drop and chain drift, and in severe cases, even chain breakage. 3. Debris such as gangue, ironware, and wood mixed in with the coal can easily enter the slide rail along with the coal, and then enter the head and tail wheels of the scraper conveyor, which not only aggravates equipment wear, but also easily causes safety accidents. 4. The existing guide rails have right-angled guard plates on both sides, which increase the resistance when the scraper chain transitions, further increasing the risk of chain drop. In addition, the overall structure requires frequent maintenance, resulting in high material consumption and labor costs. This leads to low operating efficiency and poor economic benefits of the scraper conveyor, making it difficult to meet the high-efficiency and energy-saving production needs of the clean coal bunker. Utility Model Content

[0003] In view of the problems mentioned above in the background technology, the purpose of this utility model is to provide a high-efficiency material guiding slide rail for a scraper conveyor in a coal bunker.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A high-efficiency guide rail for a scraper conveyor in a clean coal bunker includes a rail body, a coal feeding guide assembly, a debris filter, and an arc-shaped protective chain plate. The rail body includes an upper flange, a lower flange, and a web connecting the upper and lower flanges. The coal feeding guide assembly is fixedly installed above the middle of the upper flange of the rail body. The debris filter is detachably installed at the top inlet of the coal feeding guide assembly. The arc-shaped protective chain plate is symmetrically fixed on both sides of the upper flange of the rail body, and its inner side is an arc surface.

[0005] Preferably, the coal feeding and guiding assembly includes a guiding hopper and a guiding inclined plate; the bottom outlet of the guiding hopper is fixedly connected to the guiding inclined plate.

[0006] Preferably, the debris filter element is a grid structure; a collection box can also be detachably installed on one side of the debris filter element, and the collection box is a box structure with an open top.

[0007] Preferably, the web of the slide rail body is provided with a plurality of lubrication holes evenly distributed, the lubrication holes penetrating the thickness direction of the web, and each lubrication hole has an internal thread on its inner wall.

[0008] Preferably, the arc-shaped chain guard plate is fixedly connected to one side of the upper flange of the slide rail body by multiple bolts, and the inner arc surface of the arc-shaped chain guard plate is adapted to the movement trajectory of the scraper chain of the scraper machine; a wear-resistant layer is also fixedly attached to the inner side of the arc-shaped chain guard plate.

[0015] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] This utility model provides a method such as Figures 1 to 5 The diagram shows a high-efficiency guide rail for a scraper conveyor in a coal bunker, comprising a rail body 1. The rail body 1 includes an upper flange 11, a lower flange 12, and a web 13 connecting the upper flange 11 and the lower flange 12. A coal feeding guide assembly 2 is fixedly installed above the middle of the upper flange 11 of the rail body 1. A debris filter 3 is detachably installed at the top inlet of the coal feeding guide assembly 2. Arc-shaped chain guards 4 are symmetrically fixed on both sides of the upper flange 11 of the rail body 1.

[0017] Example 1: As Figure 1 , Figure 2 As shown, the coal feeding guide assembly 2 includes a feeding hopper 21 and a feeding inclined plate 22. The bottom outlet of the feeding hopper 21 is fixedly connected to the feeding inclined plate 22. A buffer pad 23 is also fixedly attached to the inner wall of the feeding hopper 21. The buffer pad 23 is made of rubber. In this utility model, the working steps of the device are as follows: First, the slide rail body 1 is fixedly connected to the head and tail of the scraper conveyor through the positioning connecting plates 14 at both ends. The connecting holes 141 on the positioning connecting plates 14 facilitate the use of fasteners to fix it, ensuring that the slide rail body 1 is installed firmly. When the coal is falling, the clean coal enters through the guide hopper 21 of the coal falling guide assembly 2. The buffer pad 23 on the inner wall of the guide hopper 21 can reduce the impact force of the falling coal and avoid direct impact on the scraper chain. The falling coal is then accurately guided to the center of the scraper by the guide inclined plate 22 to prevent the falling coal from deviating and effectively solve the problems of chain drop and chain drift.

[0018] Example 2: Figure 4 As shown, the debris filter element 3 is a grid structure, and a collection box 31 is fixedly connected to one side of the debris filter element 3. The collection box 31 is a box structure with an open top. In this utility model, the working steps of the device are as follows: During the coal falling process, mixed gangue, ironware, wood and other debris enter the top of the guide hopper 21 along with the falling coal. The grid structure of the debris filter 3 can intercept larger debris and prevent it from entering the scraper conveyor. The intercepted debris falls into the collection box 31. The collection box 31 can be disassembled and cleaned regularly to avoid debris damaging the scraper conveyor equipment and extend the service life of the equipment.

[0019] Example 3: Figure 3 , Figure 5 As shown, a plurality of lubrication holes 131 are evenly provided on the web plate 13 of the slide rail body 1. The lubrication holes 131 penetrate through the thickness direction of the web plate 13, and the inner wall of each lubrication hole 131 is provided with internal threads. The arc-shaped chain guard plate 4 is fixedly connected to one side of the upper flange 11 of the slide rail body 1 by a plurality of bolts 41. The inner arc surface of the arc-shaped chain guard plate 4 is adapted to the movement trajectory of the scraper chain of the scraper machine. The inner side of the arc-shaped chain guard plate 4 is also fixedly attached with a wear-resistant layer 42. A plurality of support seats 15 are also fixedly connected to the bottom of the lower flange 12 of the slide rail body 1. The support seats 15 are evenly distributed along the length direction of the slide rail body 1, and the bottom of the support seats 15 is a planar structure. In this utility model, the working steps of the device are as follows: When the scraper chain runs on the slide rail body 1, the arc surface design of the arc guard plate 4 ensures a smooth transition of the scraper chain, reduces running resistance, and avoids chain jamming and chain drop. The wear-resistant layer 42 further extends the service life of the arc guard plate 4. Lubricant can be periodically added to the slide rail through the lubrication hole 131 to reduce friction between the scraper chain and the slide rail and reduce energy consumption. The support seat 15 provides stable support to ensure that the slide rail body 1 remains horizontal during operation and improves the overall operating efficiency.
