Description

Technical Field

[0001] The invention relates to the technical field of production and transportation, in particular to a coal conveying belt sealing system. Background Art

[0002] At a thermal power generation site, a conveyor belt is an important device for conveying power generation materials. In addition, due to the complex environment of the power generation site, it is often necessary to transport coal over a long distance. A conveying device is often formed by a rack and a plurality of belts installed in series on the rack. Adjacent belt conveyors are provided with intervals. They can be butt-jointed to form a structure with the top surface on the same horizontal plane, or overlapped to form a stepped structure. A driving mechanism is provided on each belt conveyor, and the running directions of the plurality of belt conveyors are consistent, but the running speeds of the belt conveyors can be different or the same, so that the speed of each belt conveyor can be adjusted separately, thereby achieving product separation or concentration, and improving practicality. However, there is a height difference between the stepped conveyor belts. During the transportation process between adjacent belts, when the coal falls from a high place to a low place, a large amount of coal ash will be raised due to the fall, which not only damages the production site environment, but also affects the physical safety of the on-site staff, and also causes serious fire hazards. Therefore, it is necessary to surround and seal this falling transfer area with a sealed box.

[0003] However, if the iron sealing box is in direct contact with the belt, the belt will be worn, which is not conducive to the long-term operation of the equipment. In addition, due to the position deviation caused by the movement of the belt, a gap will be generated between the box and the belt, and coal ash will leak out from the gap. Therefore, the connection between the box and the belt needs to be filled with other materials or structures. Summary of the invention

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Example 1, reference Figures 1 to 3 , is the first embodiment of the present invention, which provides a coal conveyor belt sealing system, including, a dust prevention component 100, including a sealing box 101 and a side guide box 104 arranged at the bottom of the sealing box 101, the sealing box 101 will wrap the coal falling from the belt on the top of the sealing box 101 to the bottom of the sealing box 101, and implement sealing to prevent the coal ash raised by the falling coal from leaking and spreading to the production site, reduce environmental pollution of the coal conveying system, eliminate fire hazards, protect the occupational health of workers, and reduce the labor cost of sanitation and cleaning, and at the same time, the side guide box 104 fills the gap between the sealing box 101 and the belt at the bottom of the sealing box 101 to prevent the coal ash from leaking out of this gap; and,

[0025] The dust removal component 200 includes a dust suction fan 201 arranged on the top of the sealed box 101 and a dust suction hood 204 arranged on the bottom of the dust suction fan 201. Due to transportation needs, an opening is provided at one end of the sealed box 101 away from the high belt, so that the coal can be transported out of the sealed box 101. It is inevitable that coal ash will leak at this opening. In order to deal with the leaked coal ash, the dust removal component 200 is required to collect and remove the dust.

[0026] Specifically, the sealed box 101 wraps the coal that falls from the belt on the top of the sealed box 101 to the bottom of the sealed box 101, and seals it to prevent the coal ash raised by the falling coal from leaking and spreading to the production site. At the same time, the side guide box 104 fills the gap between the sealed box 101 and the belt at the bottom of the sealed box 101 to prevent the coal ash from leaking out of this gap. The dust removal component 200 collects the coal ash leaked from the opening of the sealed box 101.

[0027] Example 2, reference Figures 1 to 3 , which is the second embodiment of the present invention, is different from the previous embodiment in that a fixing frame 102 is provided on the outer wall of the sealed box 101 , a coal dropping pipe 103 is provided on the top of the sealed box 101 , and the coal dropping pipe 103 is connected to the sealed box 101 .

[0028] Furthermore, the side guide box 104 includes a strip box body 104a, which is made of rubber. The strip box body 104a wraps the bottom of the sealed box 101 and leaves an opening on one side. The strip box body 104a surrounds the sealed box 101 from three sides, leaving an opening on one side so that the coal can be transported out smoothly. A through hole 104b is opened on the top of the strip box body 104a, and the inner wall of the through hole 104b is in contact with the side through pipe 205. The interior of the strip box body 104a is provided with an oblique comb tooth bar 104c, which is made of rubber. 104c extends toward the belt on the strip box 104a and is inclined toward the forward direction of the belt. During the movement of the belt, the coal moving on the belt will be led by the oblique comb teeth 104c to move toward the middle of the belt to prevent too much coal from moving toward the edge of the strip box 104a to cause blockage or leakage. A coal outlet 105 is provided on one side of the bottom of the sealed box 101, a connecting plate 106 is provided on the top of the coal outlet 105, and a baffle 107 is provided on the bottom of the connecting plate 106. When the coal is transported out from the coal outlet 105, a small amount of coal ash will leak from between the baffles 107.

[0029] Specifically, the top of the coal drop pipe 103 is in contact with the high belt, and the coal dropped from the high belt enters the sealing box 101 from the coal drop pipe 103. The sealing box 101 wraps and seals the area where the coal falls to prevent leakage. At the same time, the strip box 104a is made of rubber. The bottom of the strip box 104a is provided with a groove, which is used to engage with the edge of the belt. The rubber material can reduce the wear on the belt. The strip box 104a seals the gap between the bottom of the sealing box 101 and the belt to prevent coal ash from leaking from the gap.

[0030] Example 3, reference Figures 1 to 3 , which is the third embodiment of the present invention, is different from the previous embodiment in that a dust collector 202 is provided on the top of the dust suction fan 201, the dust collector 202 is connected to the dust suction fan 201, and the dust collector 202 is fixed to the top of the sealing box 101 through a bracket.

[0031] Furthermore, a dust suction pipe 203 is provided on the side of the dust collector 202, and the dust suction pipe 203 is connected to the dust suction fan 201. The bottom of the dust suction pipe 203 is connected to the dust suction hood 204, and the top of the dust suction hood 204 is connected to the dust suction pipe 203. The cross-section of the dust suction hood 204 is trapezoidal, and the dust suction hood 204 is located directly above the coal outlet 105. When the dust suction fan 201 is started, a small amount of coal ash leaked from the coal outlet 105 will be sucked into the dust collector 202 through the dust suction pipe 203 and the dust suction hood 204, and the dust collector 202 collects the coal ash.

[0032] Furthermore, side passages 205 are provided on both sides of the dust suction main pipe 203, the side passages 205 are connected to the dust suction main pipe 203, the outer wall of the side passages 205 is connected to the fixed frame 102, the bottom of the side passages 205 is connected to the side guide box 104, and the side passages 205 are connected to the side guide box 104. When the dust suction fan 201 is working, the coal ash accumulated in the side guide box 104 will be sucked into the dust collector 202 through the side passages 205, and the dust collection will be completed in the dust collector 202.

[0033] Specifically, when the dust suction fan 201 is started, a small amount of coal ash leaked from the coal outlet 105 will be sucked into the dust collector 202 through the dust suction main pipe 203 using the dust suction hood 204, and the dust collector 202 will collect the coal ash. At the same time, the dust suction fan 201 will suck the coal ash accumulated in the side guide box 104 into the dust collector 202 through the side passage pipe 205, and complete the dust collection in the dust collector 202.
