Description

Technical Field

[0001] This utility model relates to the field of coal conveying technology, and in particular to a flow guiding mechanism for a coal conveyor. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] As the core equipment of the power plant's coal conveying system, the coal conveyor is responsible for the entire process of transporting coal from the unloading point to the boiler before combustion.

[0004] Because the unloaded coal is conveyed onto the coal conveyor through an inclined chute, it is very easy for the material to concentrate and impact one side of the coal conveyor, causing the conveyor belt to deviate and spill. To solve this problem, the traditional approach is to install a guide baffle at the outlet of the chute, so that the coal discharged from the chute impacts the guide baffle and falls down along the guide baffle, changing the impact from lateral to downward. However, the above-mentioned guide baffle is subject to the impact of coal for a long time during use, and it is very easy to wear and damage, resulting in a short service life and frequent replacement, which makes it impossible for the coal conveyor to maintain long-term stable operation. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings by providing a guiding mechanism for a coal conveyor, thereby reducing the unbalanced impact of coal on the conveyor and minimizing maintenance frequency.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a guiding mechanism for a coal conveyor, comprising:

[0007] Two guide pipes, the discharge ends of both guide pipes are located above the belt conveyor, and the discharge direction of one guide pipe is opposite to the discharge direction of the other guide pipe, so that the material discharged from the two guide pipes collides with each other and falls.

[0008] The branch pipe has one end connected to the coal chute and the other end connected to the feed ends of the two guide pipes, so that the material discharged from the coal chute enters the two guide pipes respectively.

[0009] Furthermore, the branch pipe is provided with a dividing plate for dividing the material in the branch pipe into two streams, and the dividing plate is wedge-shaped to guide the flow of material in the branch pipe and reduce dead zones.

[0010] Furthermore, the guide pipe is equipped with a U-shaped baffle located above the belt conveyor. The opening direction of the U-shaped baffle is consistent with the discharge direction of the belt conveyor, which is used to prevent the material from splashing out of the belt conveyor during collision.

[0011] Furthermore, a V-shaped scraper located above the belt conveyor is provided on the side of the guide pipe near the discharge direction of the belt conveyor. The opening direction of the V-shaped scraper is consistent with the discharge direction of the belt conveyor, and it is used to push the material in the middle to both sides when the material is moving.

[0012] Furthermore, both the feed pipe and the branch pipe are detachably equipped with multiple liners to protect them from direct impact and friction from the material.

[0013] The beneficial effects of this utility model are reflected in:

[0014] This invention involves guiding the coal discharged from the coal drop pipe through a branch pipe into two guide pipes. Because the two guide pipes are positioned with opposite discharge directions, the discharged coal collides and slows down before falling onto the belt conveyor below. This avoids the coal directly impacting the side wall of the belt conveyor after exiting the guide pipes. Furthermore, since the deceleration process is completed by the collision of two coal streams after exiting the guide pipes, the wear on the guide pipes is minimal, allowing them to stably transport coal for extended periods.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-3 This utility model discloses a flow guiding mechanism for a coal conveyor, comprising:

[0022] Two guide pipes 1, the discharge ends of both guide pipes 1 are located above the belt conveyor, and the discharge direction of one guide pipe 1 is opposite to the discharge direction of the other guide pipe 1, so that the material discharged from the two guide pipes 1 collide with each other and falls.

[0023] Branch pipe 2 has one end connected to the coal chute and the other end connected to the feed end of the two feed pipes 1, so that the material discharged from the coal chute can enter the two feed pipes 1 respectively.

[0024] This invention guides the coal discharged from the coal drop pipe through the branch pipe 2 into two guide pipes 1. Because the discharge directions of the two guide pipes 1 are opposite, the discharged coal collidees with each other and slows down before falling onto the belt conveyor below. This avoids the coal directly impacting the side wall of the belt conveyor after being discharged from the guide pipes 1. Furthermore, since the deceleration process of the coal is completed by the collision of two coal streams after being discharged from the guide pipes 1, the wear on the guide pipes 1 is small, enabling the guide pipes 1 to stably transport coal for a long time.

[0025] It should be noted that by placing the collision point of the two coal streams in the middle of the belt conveyor, the leakage of coal can be effectively reduced.

[0026] In one embodiment, the branch pipe 2 is provided with a dividing plate 3 for dividing the material in the branch pipe 2 into two streams, and the dividing plate 3 is wedge-shaped to guide the flow of material in the branch pipe 2 and reduce dead zone areas.

[0027] This design allows the material entering the branch pipe 2 to be divided into two streams by the distribution plate 3 during flow. By adjusting the position of the distribution plate 3, the two streams of material can be divided as evenly as possible, and dead corners can be blocked by the distribution plate 3, thus improving the smoothness of coal flow.

[0028] In one embodiment, a U-shaped baffle 4 is provided on the feed pipe 1 above the belt conveyor. The opening direction of the U-shaped baffle 4 is consistent with the discharge direction of the belt conveyor, which is used to prevent the material from splashing out of the belt conveyor.

[0029] This design, by placing the U-shaped baffle 4 at the point of coal collision, can intercept and block some of the outward-splashing coal when the two coal streams collide, thus ensuring that the coal can be driven and transported by the belt conveyor as much as possible. At the same time, because the opening direction of the U-shaped baffle 4 is consistent with the discharge direction of the belt conveyor, the U-shaped baffle 4 will not obstruct the output of the coal.

[0030] In one embodiment, a V-shaped scraper 5 located above the belt conveyor is provided on the side of the guide pipe 1 near the discharge direction of the belt conveyor. The opening direction of the V-shaped scraper 5 is consistent with the discharge direction of the belt conveyor, and it is used to push the middle material to both sides when the material is moving.

[0031] With this design, when the height of the coal on the belt conveyor exceeds the bottom height of the V-shaped scraper 5, the coal will be pushed to both sides by the V-shaped scraper 5 as it passes through the V-shaped scraper 5, filling the empty space on both sides. This can prevent the coal from accumulating in the middle and causing uneven tension on both sides of the belt.

[0032] In one embodiment, both the feed pipe 1 and the branch pipe 2 are detachably provided with multiple liners to protect them from direct impact and friction from the material.

[0033] This design allows the liner to directly contact the coal. When some of the liners are severely worn, only the liner in that area needs to be replaced, which reduces subsequent maintenance costs.

[0034] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0035] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0036] Additionally, "multiple" refers to two or more.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
