Description

Technical Field

[0001] This utility model relates to the field of metallurgical machinery technology, and in particular to a coal injection inclined belt anti-coal siltation device. Background Technology

[0002] In the pulverized coal feeding system, the raw coal is damp, and excessive material sticking to the lower part of the inclined conveyor belt leads to a large amount of coal accumulation in the lower part of the conveyor corridor, resulting in a heavy load. This can cause coal siltation in the coal conveying section of the ditch. Material sticking to the conveyor rollers can also cause the belt to run off-track, which in turn affects normal coal feeding. Material shortage in the raw coal bunker affects the pulverizing system and the operation of pulverized coal injection into the blast furnace, thus affecting production. Material sticking to the belt and falling off also affects the production site environment and the labor intensity of workers.

[0003] Currently, in the process of injecting pulverized coal into blast furnaces, a stable and continuous supply of coal to the raw coal bunker is required via an inclined conveyor belt. However, excessive material adhering to the lower part of the inclined conveyor belt can lead to coal accumulation in the conveyor corridor, potentially causing coal siltation in the coal conveying section of the ditch. Material adhering to the conveyor rollers can also cause belt misalignment, affecting normal belt operation. A fully loaded conveyor belt cannot be restarted, thus affecting the pulverizing system's normal pulverizing process, and consequently preventing normal pulverization into the blast furnace, resulting in production disruptions. When coal siltation occurs, the large amount of silt makes it difficult for production personnel to clean it up and restore coal supply in a timely manner, significantly impacting production. Based on the above analysis, solving the problem of material adhering to the lower part of the conveyor belt can effectively prevent coal accumulation. Therefore, designing a method that can effectively handle material adhering without affecting the conveyor belt's coal supply is a technical problem that needs to be solved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a coal siltation prevention device for inclined conveyor belts that can clean the raw coal adhering to the bottom of the inclined conveyor belt and reduce the moisture content of the raw coal.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A coal injection inclined belt anti-coal-accumulation device includes a coal shed, an inclined belt inclined upward from the coal shed, a feeding hopper located below the port of the inclined belt, a main belt located below the feeding hopper, several raw coal bins connected to the main belt, a vibrator located at the corner of the inclined belt, a collection hopper located below the vibrator, and a transfer belt located below the collection hopper; a baffle is provided between the feeding hopper and the collection hopper; the collection hopper is provided with a hot air inlet.

[0007] A further improvement of this utility model is that the inclination angle of the baffle is greater than 30°.

[0008] A further improvement to the technical solution of this utility model is that a heating coupler is installed inside the baffle.

[0009] A further improvement of this utility model is that the transfer belt is horizontally connected to the main belt.

[0010] A further improvement of this utility model is that a coal leakage hole is provided below the vibrator.

[0011] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:

[0012] 1. This utility model can prevent the situation where material sticking to the lower part of the conveyor belt causes excessive coal accumulation in the conveyor corridor, which affects the pulverizing and injection systems. It also greatly reduces the labor intensity of workers, reduces the possibility of coal sludge on the conveyor belt, ensures a stable supply of raw coal, and lays a solid foundation for stable blast furnace injection, high output, low consumption, and stable operation of the blast furnace. It also reduces the labor intensity of workers and contributes to the company's reduction of production costs.

[0013] 2. In this utility model, the collecting hopper is equipped with a hot air inlet, and a thermocouple is installed inside the baffle to heat the raw coal with high humidity, thereby reducing the humidity of the raw coal. Attached Figure Description

[0018] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0019] like Figure 1 As shown, a coal injection inclined belt anti-coal siltation device includes a coal shed 1, an inclined belt inclined upward from the coal shed 1, a feeding hopper 3 located below the port of the inclined belt, a main belt 4 located below the feeding hopper 3, several raw coal bins 5 connected to the main belt 4, a vibrator 6 located at the corner of the inclined belt 2, a collection hopper 7 located below the vibrator 6, and a transfer belt 8 located below the collection hopper 7.

[0020] A baffle 9 is provided between the feeding hopper 3 and the collecting hopper 7. The inclination angle of the baffle 9 is greater than 30°, and a heating coupler is provided inside the baffle 9.

[0021] The collection hopper 7 is equipped with a hot air inlet;

[0022] The transfer belt 8 is horizontally connected to the main belt 4;

[0023] A coal leakage hole is provided below the vibrator 6.

[0024] Working principle:

[0025] The inclined conveyor belt transports raw coal from the coal shed 1 to the unloading hopper 3, and then onto the main conveyor belt 4, which transports it to each raw coal bunker 5. When the inclined conveyor belt turns back to the coal shed 1 from below, some raw coal is still stuck to it. It is vibrated by the vibrator 6 onto the baffle 9, and then slides into the collection hopper 7. The raw coal is heated by the heating coupler, and hot air is introduced into the hot air inlet of the collection hopper 7 to dry the damp raw coal. The coal then enters the transfer conveyor belt 8 through the collection hopper 7 and is transported to the main conveyor belt 4, and finally to each raw coal bunker 5.

[0026] In summary, this invention can clean the raw coal adhering to the underside of the inclined conveyor belt and reduce the moisture content of the raw coal.
