Description

Technical Field

[0001] This utility model relates to the field of coal conveying corridor technology, and in particular to an environmentally friendly coal conveying corridor. Background Technology

[0002] A coal conveying corridor is a channel for transporting coal. Conveyors are installed inside the coal conveying corridor, and coal is transported through the corridor using these conveyors.

[0003] During the coal transportation process, the vibrations generated by the conveyor itself and the airflow generated during the transportation process will cause the coal on the conveyor belt to generate and disperse coal dust to the surrounding area, affecting the environment inside the corridor and posing a significant respiratory safety risk to patrol personnel. In addition, for some semi-enclosed corridors, coal dust will be dispersed outside the corridor, causing pollution to the surrounding environment.

[0004] To address this issue, existing technologies involve installing spray pipes above the conveyor belt and spraying water mist through atomizing nozzles to prevent coal ash from escaping. However, with increased weight, the coal ash and water mist will fall back onto the coal on the conveyor belt, making it difficult to control the moisture content of the coal and adversely affecting subsequent coal processing. Utility Model Content

[0005] The main purpose of this invention is to propose an environmentally friendly coal conveying corridor, which aims to reduce the amount of water mist that falls back onto the coal and reduce its impact on the moisture content of the coal.

[0006] To achieve the above objectives, the environmentally friendly coal conveying corridor proposed in this utility model includes:

[0007] belt;

[0008] A spraying device is located above the center of the belt and is used to spray water mist to both sides.

[0009] Two water tanks are located on both sides of the belt, and the water tanks extend along the conveying direction of the belt.

[0010] Two water mist guiding devices are located on both sides of the spraying device, and the water mist guiding devices are used to guide the water mist sprayed by the spraying device into the water tank.

[0011] In one embodiment, the water mist guiding device includes a stop bracket located on the top of the water tank away from the belt. The stop bracket is inclined toward the belt and is used to block the water mist sprayed by the spraying device and guide the water mist into the water tank.

[0012] In one embodiment, the top of the stop frame is provided with a top plate, which extends toward the spraying device.

[0013] In one embodiment, the stop frame has a plurality of observation windows below it, and the observation windows are made of transparent material.

[0014] In one embodiment, the observation window is made of PVC material.

[0015] In one embodiment, the water mist guiding device further includes a guide frame located on the top of the water tank near the belt, the guide frame being used to guide the coal-water mixture dripping from the stop frame into the water tank.

[0016] In one embodiment, the guide frame is inclined toward the belt direction, and one end of the guide frame near the spray device protrudes from the stop frame.

[0017] In one embodiment, the flow guide includes:

[0018] Multiple guide rods are connected to the water tank, and the multiple guide rods are evenly spaced along the extension direction of the water tank;

[0019] A guide plate is connected to multiple guide rods. After the coal-water mixture on the stop frame drips onto the guide plate, it flows into the water tank through the guide rods.

[0020] In one embodiment, the spraying device includes:

[0021] The frame is connected to the top plate;

[0022] Pipeline, which is located above the frame;

[0023] Multiple atomizing nozzles are evenly distributed on both sides of the pipe.

[0024] In one embodiment, the frame is an arc-shaped plate with the opening facing upwards.

[0025] The technical solution provided by this utility model includes an environmentally friendly coal conveying corridor comprising a belt conveyor, a spraying device, two water troughs, and two water mist guiding devices. The spraying device is located above the center of the belt conveyor and is used to spray water mist to both sides. The two water troughs are located on both sides of the belt conveyor and extend along the conveying direction of the belt. The two water mist guiding devices are located on both sides of the spraying device and are used to guide the water mist sprayed by the spraying device into the water troughs. This solution, by setting up water mist guiding devices, guides the water mist after it has absorbed coal ash into the water troughs, reducing the amount of water mist that falls back onto the coal and minimizing its impact on the moisture content of the coal.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

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.

[0035] Existing technology involves installing spray pipes above the conveyor belt and spraying water mist through atomizing nozzles to prevent coal ash from escaping. However, with the increased weight of the coal ash water mist, it will fall back onto the coal on the conveyor belt, making it difficult to control the moisture content of the coal and adversely affecting subsequent coal processing.

[0036] To address this technical problem, this utility model provides an environmentally friendly coal conveying corridor 1000, comprising a belt conveyor 1, a spraying device 2, two water tanks 3, and two water mist guiding devices 4. The spraying device 2 is located above the center of the belt conveyor 1 and is used to spray water mist to both sides. The two water tanks 3 are located on both sides of the belt conveyor 1, extending along the conveying direction of the belt conveyor 1. The two water mist guiding devices 4 are located on both sides of the spraying device 2 and are used to guide the water mist sprayed by the spraying device 2 into the water tanks 3. This solution, by setting up the water mist guiding devices 4, guides the water mist after it has absorbed coal ash into the water tanks 3, reducing the amount of water mist that falls back onto the coal and minimizing its impact on the coal's moisture content. Simultaneously, the water tanks 3 can collect the coal-water mixture for further processing.

[0037] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the water mist guiding device 4 includes a stop frame 41. The stop frame 41 is located on the top of the water tank 3 away from the belt 1. The stop frame 41 is inclined towards the belt 1 and is used to stop the water mist sprayed by the spraying device 2 and guide the water mist into the water tank 3. With the inclined stop frame 41 in place, since the spraying direction of the spraying device 2 is towards the stop frame 41, after the spraying device 2 sprays, it absorbs the coal ash in the spraying direction and sprays it onto the surface of the stop frame 41. Subsequently, the coal-water mixture flows along the inclined stop frame 41 into the water tank 3, completing the collection.

[0038] Please see Figure 2In one embodiment of this utility model, the top of the stop frame 41 is provided with a top plate 42, which extends toward the spraying device 2. If the amount of coal ash is large, the coal ash may not be completely absorbed by the water mist. By providing the top plate 42, the coal ash is prevented from escaping to the outside, ensuring that it can be completely absorbed by the water mist.

[0039] Please see Figure 2 In one embodiment of this utility model, a plurality of observation windows 43 are provided below the stop bracket 41, and the observation windows 43 are made of transparent material. By setting the observation windows 43, the transportation status of coal on the conveyor belt 1 can be observed through the observation windows 43, thereby improving practicality.

[0040] Among them, observation window 43 is made of PVC. PVC, or polyvinyl chloride, is a thermoplastic with good transparency and waterproof properties. Transparent PVC sheets have good physical properties and a relatively low price. Since coal conveying corridors are generally quite long, using PVC for observation windows 43 can reduce construction costs.

[0041] Please see Figure 2 In one embodiment of this utility model, the water mist guiding device 4 further includes a guide frame 44, which is located on the top of the water tank 3 near the belt 1. The guide frame 44 is used to guide the coal-water mixture dripping from the stop frame 41 into the water tank 3. By setting the guide frame 44, when the coal-water mixture condensed on the stop frame 41 is heavy and drips, it drips onto the guide frame 44 and enters the water tank 3 through the guide frame 44.

[0042] The guide frame 44 is inclined towards the belt 1, and the end of the guide frame 44 near the spray device 2 protrudes from the stop frame 41. This arrangement ensures that water droplets falling from any position on the stop frame 41 can be caught by the guide frame 44.

[0043] Please see Figure 2 In one embodiment of this utility model, the flow guide 44 includes:

[0044] Multiple guide rods 441 are connected to the water tank 3, and the multiple guide rods 441 are evenly spaced along the extension direction of the water tank 3.

[0045] The guide plate 442 is connected to multiple guide rods 441. After the coal-water mixture on the stop frame 41 drips onto the guide plate 442, it flows into the water tank 3 through the guide rods 441.

[0046] The spaced guide rods 441 ensure that patrol personnel can observe the conveyor belt 1 and coal transportation through the observation window 43 and the gaps between the guide rods 441, ensuring that their line of sight is not blocked by the guide frame 44.

[0047] Please see Figure 2 In one embodiment of this utility model, the spraying device 2 includes:

[0048] Frame 21, which is connected to the top plate 42;

[0049] Pipe 22 is located above frame 21;

[0050] Multiple atomizing nozzles 23 are evenly distributed on both sides of the pipe 22.

[0051] Atomizing nozzles 23 are installed on both sides of the pipe 22, and the atomizing nozzles 23 on both sides are supplied with water through a single pipe 22. The structure is relatively simple and the cost is low.

[0052] The frame 21 is an arc-shaped plate with its opening facing upwards. By making the frame 21 an arc-shaped plate, when the coal ash at the bottom is raised, the arc surface can guide the coal ash to the spray area on both sides of the frame 21, thereby improving the adsorption efficiency.

[0053] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
