Abstract
Description
Technical Field
[0001] This disclosure relates to the field of coal feeder technology, and in particular to a coal feeder water guiding mechanism and a coal feeder. Background Technology
[0002] Currently, there is a large amount of material transportation and transshipment in the mining industry. Taking coal material transportation as an example, raw coal enters the raw coal bunker via a raw coal conveyor belt. A coal feeder is usually installed under the raw coal bunker to achieve material buffering and uniform feeding. In actual production, the discharge end of the coal feeder needs to extend into the bottom receiving chute 7 to ensure that the material does not spill out. Figure 1 As shown. Similarly, for transfers between other chutes, it is necessary to consider that the discharge end extends into the interior of the receiving chute 7.
[0003] During the raw coal production process, the influence of different geological conditions and mining techniques often results in the introduction of large amounts of moisture. This leads to water control issues during storage, where moisture leaks out from the gaps between materials even when no material is being transported. This moisture eventually flows through the coal feeder into the belt conveyor below. Over time, this water accumulates on the belt conveyor, causing a large amount of water to rush towards the head of the conveyor during startup. This water either enters the subsequent production system, causing disruptions, or spills from the head of the conveyor, entering the head drive drum and lower belt, causing the belt conveyor to deviate or slip, resulting in coal spillage, affecting production, or causing fires due to overheating, or even electromechanical accidents that damage the belt conveyor equipment.

[0030] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.
[0031] In existing technologies, in order to eliminate the impact of water spraying from the coal feeder on the production system, the usual measure is to start the belt conveyor in advance a period of time before the equipment starts running to drain the accumulated water into the subsequent stages in stages. This will affect the subsequent production system. At the same time, the equipment needs to be stopped after the water on the belt conveyor is drained, and it can only be restarted after the water on the belt rollers and the lower belt of the belt is drained. This will increase power consumption and increase the safety hazards of equipment operation.
[0032] This disclosure provides a water guiding mechanism for a coal feeder, which can drain water from the coal feeder when it is stopped, preventing it from entering the subsequent conveyor belt.
[0033] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.
[0034] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this embodiment of the present disclosure provides a water guiding mechanism for a coal feeder, including: a coal feeder base plate 1, a water guiding plate 2, and a water guiding rod 3;
[0035] The coal feeder base plate 1 is used to convey materials, such as coal minerals. It includes a discharge end, which is located at the lowest end of the coal feeder base plate 1. The coal feeder is equipped with a vibration device. Under the action of vibration, the material is conveyed to a lower position on the coal feeder base plate 1 and finally falls from the discharge end and is discharged into the subsequent equipment.
[0036] The water guide plate 2 is located below the discharge end, so that the liquid flowing out of the material can flow downward through the water guide plate 2 under the action of surface tension and gravity.
[0037] The water guide rod 3 is located below the water guide plate 2. The water guide rod 3 includes a proximal end and a distal end. The proximal end is connected to the lower end of the water guide plate 2, and the distal end is far away from the discharge end. The liquid flowing out of the material can pass through the water guide plate 2 and the water guide rod 3 in sequence and be discharged. Under the action of surface tension and gravity, the liquid flows along the water guide rod 3 and finally flows down from the distal end.
[0038] The water guiding mechanism of the coal feeder in this embodiment can drain the water in the coal feeder when it is stationary, thereby eliminating the water accumulation phenomenon in the subsequent conveyor belt caused by water spraying from the coal feeder. It also eliminates the problem of the water spraying into the conveyor belt causing the drainage of the conveyor belt during startup to affect the subsequent production system, as well as the electromechanical hazards of conveyor belt deviation and slippage.
[0039] In some possible implementations, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the guide plate 2 is flush with the discharge end, so that the liquid flowing out of the material can flow downward through the guide plate 2 in the shortest path under the action of surface tension and gravity, avoiding flowing in other directions.
[0040] In some possible implementations, such as Figure 2 , Figure 3 , Figure 4 As shown, the water guide plate 2 is a triangular plate cut from a steel plate. It can be a right-angled triangle or an obtuse-angled triangle. The upper side is fixedly connected to the coal feeder bottom plate 1, and the lower side is inclined to guide the liquid downward.
[0041] In some possible implementations, such as Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, it also includes: a coal retaining plate 4 and a water guide hole 5;
[0042] The coal retaining plate 4 is made of steel plate and has an installation groove 6. The width of the installation groove 6 is slightly larger than the width of the coal feeder bottom plate 1. The discharge end of the coal feeder bottom plate 1 passes through the installation groove 6. During the process of material falling, the coal feeder bottom plate 1 can block the material from scattering and prevent the material from falling outward, and guide it into the subsequent equipment.
[0043] The water guide hole 5 can be either round or rectangular. It is located on the coal baffle plate 4, and the distal end of the water guide rod 3 passes through it, extending away from the discharge end to guide the liquid to a safe location, preventing it from flowing into subsequent equipment. Preferably, the distal end slopes downwards, which facilitates liquid flow.
[0044] In some possible implementations, such as Figure 2 , Figure 3 , Figure 5 As shown, the water guide rod 3 is a circular rod with at least one bend, which can be a 90-degree bend. The bend is inserted into the water guide hole 5. The circular rod facilitates the flow of liquid along the water guide rod 3. The bend design keeps the far end of the water guide rod 3 away from the discharge end and away from subsequent equipment.
[0045] In some possible implementations, such as Figure 2 , Figure 3 , Figure 5 As shown, the bend of the water guide rod 3 is not less than 90 degrees. If the bend is less than 90 degrees, it is not convenient for the water guide rod 3 to pass through the water guide hole 5, so it needs to be set to a bend of 90 degrees or greater.
[0046] In some possible implementations, such as Figure 2 , Figure 3 , Figure 4 As shown, the water guide rod 3 does not contact the coal retaining plate 4, especially not the inner wall of the water guide hole 5, so that all the liquid flows along the water guide rod 3 and avoids the liquid flowing onto the coal retaining plate 4.
[0047] In some possible implementations, such as Figure 2 , Figure 3 , Figure 4 As shown, the bottom plate 1 of the coal feeder is an inverted trapezoidal groove structure, which is made by bending or welding steel plates. This design is conducive to material conveying, and it has a straight edge at the discharge end, which facilitates the connection of the water guide plate 2.
[0048] In some possible implementations, such as Figure 2 , Figure 3 , Figure 4 As shown, the water guide plate 2 is welded and fixed to the coal feeder base plate 1, and the water guide rod 3 is welded and fixed to the water guide plate 2, which can ensure a firm connection.
[0049] This disclosure also provides a coal feeder, including a coal feeder water guiding mechanism according to any one of the above embodiments.
[0050] The working process of the coal feeder water guiding mechanism is as follows:
[0051] When the coal feeder is stationary, the material accumulates on the bottom plate 1 of the coal feeder. The water in the gaps of the material flows to the bottom plate 1 of the coal feeder by gravity. Under the action of the inclined angle, the water flows from the feed end of the bottom plate 1 of the coal feeder to the discharge end and falls from the discharge end.
[0052] At this point, because a triangular water guide plate 2 is welded to the bottom of the discharge end of the coal feeder base plate 1, the water will flow along the water guide plate 2 to the bottom edge of the water guide plate 2. The water is collected and gathered along the water guide rod 3 welded to the bottom edge, and finally flows out of the coal baffle plate 4, thus realizing the drainage of the coal feeder in a static state.
[0053] The above description, with reference to the accompanying drawings, illustrates a water guiding mechanism for a coal feeder and a coal feeder according to embodiments of the present disclosure, which offers the following advantages:
[0054] This eliminates the problem of water dripping into the conveyor belt during coal feeder shutdown, which could cause the conveyor belt to start up and drain water, thus affecting the subsequent production system.
[0055] This eliminates the electromechanical hazards of water entering the conveyor belt during coal feeder shutdown, which could cause belt belt misalignment and slippage.
[0056] This solution addresses the problem of water dripping into the conveyor belt during coal feeder shutdowns, which leads to increased power consumption and safety hazards due to frequent equipment operation during belt start-up drainage.
