Description

Technical Field

[0001] This invention relates to the field of production and transportation technology, and in particular to a coal conveyor belt sealing system. Background Technology

[0002] In thermal power plants, conveyor belts are crucial equipment for transporting power generation materials. Due to the complex environment at power plants, coal often needs to be transported over long distances. Conveying devices typically consist of a frame and multiple belts connected in series on the frame. Adjacent conveyor belts are spaced apart and can be connected to form a structure with their top surfaces on the same horizontal plane, or overlapped to form a stepped structure. Each conveyor belt is equipped with a drive mechanism, and the multiple belts run in the same direction, but their speeds can differ or be the same, allowing for individual speed adjustments to separate or concentrate products, thus improving practicality. However, the stepped conveyor belts have height differences. During transfer between adjacent belts, when coal falls from a higher point to a lower point, it generates a large amount of coal ash, damaging the production environment, endangering the safety of on-site workers, and posing a serious fire hazard. Therefore, it is necessary to seal this area where coal falls into the air with a sealed enclosure.

[0003] However, if the iron sealed housing is in direct contact with the belt, the belt will be worn, which is not conducive to the long-term operation of the equipment. Moreover, the positional displacement caused by the belt movement will also create gaps between the belt and the housing, and coal ash will leak out from the gaps. Therefore, the connection between the housing and the belt needs to be filled with other materials or structures. Summary of the Invention

[0017] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. Wherein:

[0018] Figure 1 This is a schematic diagram of the overall structure of the present invention.

[0019] Figure 2 This is a schematic diagram of the side guide box in this invention.

[0020] Figure 3 This is a schematic diagram of the dust removal component in this invention. Detailed Implementation

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the 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 phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0024] Example 1, referring to Figures 1 to 3 This is the first embodiment of the present invention, which provides a coal conveyor belt sealing system, including a dustproof component 100, comprising a sealing box 101 and a side guide box 104 disposed at the bottom of the sealing box 101. The sealing box 101 encloses and seals coal that falls from the belt at the top of the sealing box 101 to the bottom of the sealing box 101, preventing coal ash from leaking and spreading to the production site, reducing environmental pollution of the coal conveying system, eliminating fire hazards, protecting the occupational health of workers, and reducing sanitation and cleaning labor costs. Simultaneously, the side guide box 104 fills the gap between the sealing box 101 and the belt at the bottom of the sealing box 101, preventing coal ash from leaking out from this gap.

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

[0026] Specifically, the sealing box 101 encloses and seals the coal that falls from the conveyor belt at the top of the sealing box 101 to the bottom of the sealing box 101, preventing the coal ash from falling and spreading to the production site. At the same time, the side guide box 104 fills the gap between the sealing box 101 and the conveyor belt at the bottom of the sealing box 101 to prevent coal ash from leaking out from this gap. The dust removal component 200 collects the coal ash that leaks from the opening of the sealing box 101.

[0027] Example 2, refer to Figures 1-3 This is the second embodiment of the present invention. Unlike the previous embodiment, the outer wall of the sealing box 101 is provided with a fixing frame 102, and the top of the sealing box 101 is provided with a coal drop pipe 103, which is connected to the sealing box 101.

[0028] Furthermore, the side guide box 104 includes a strip-shaped box body 104a, which is made of rubber. The strip-shaped box body 104a wraps around the bottom of the sealed box 101 and leaves one opening. The strip-shaped box body 104a surrounds the sealed box 101 from three sides, leaving one opening to allow coal to be transported out smoothly. A through hole 104b is provided on the top of the strip-shaped box body 104a. The inner wall of the through hole 104b is in contact with the side passage pipe 205. An oblique comb toothed rack 104c is provided inside the strip-shaped box body 104a. The oblique comb toothed rack 104c is made of rubber. 104c extends along the belt direction on the bar-shaped box 104a and is inclined in the direction of belt movement. During the belt movement, the coal moving on the belt is led by the inclined comb 104c to move towards the middle of the belt, preventing too much coal from moving to the edge of the bar-shaped box 104a, causing 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 chutes 103 contacts the conveyor belt at a higher position. The coal falling from the conveyor belt enters the sealing box 101 through the coal chutes 103. The sealing box 101 wraps and seals the area where the coal falls to prevent leakage. Meanwhile, the strip box 104a is made of rubber and has a groove at the bottom. The groove is used to engage with the edge of the conveyor belt. The rubber material can reduce wear on the conveyor belt. The strip box 104a seals the gap between the bottom of the sealing box 101 and the conveyor belt to prevent coal ash from leaking out of the gap.

[0030] Example 3, referring to Figures 1-3 This is the third embodiment of the present invention. Unlike the previous embodiment, a dust collector 202 is provided on the top of the vacuum blower 201. The dust collector 202 is connected to the vacuum blower 201 and is fixed to the top of the sealed box 101 by a bracket.

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

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

[0033] Specifically, when the dust extraction fan 201 is started, it will suck a small amount of coal ash leaking from the coal outlet 105 into the dust collector 202 through the dust extraction main pipe 203 and the dust extraction hood 204. The dust collector 202 collects the coal ash. At the same time, the dust extraction fan 201 sucks the coal ash accumulated in the side guide box 104 into the dust collector 202 through the side pipe 205, and the dust collection is completed in the dust collector 202.
