DETAILED DESCRIPTION

[0038] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0039] In the present disclosure, it should be understood that the directional words used, such as "upper" and "lower", are defined by the drawing directions of the corresponding drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, and a specific orientation structure and operation, and therefore cannot be understood as a limitation of the present disclosure. The terms "inside" and "outside" refer to the inside and outside of the corresponding structural contour.

[0040] In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element, and do not have order or importance. In addition, in the description with reference to the drawings, the same number in different drawings represents the same element.

[0041] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0042] like Figures 1 to 6As shown, the present disclosure provides a coal feeding device, including a shell 1, a feed port 2, a feeding belt 3, a dust suction structure 4 and a cleaning structure 5, the feed port 2 is arranged on one side of the shell 1, the feeding belt 3 is arranged in the shell 1, the feeding belt 3 is used to transport coal, the dust suction structure 4 is arranged in the shell 1, the dust suction structure 4 is adjacent to the feed port 2 and is connected with the interior of the shell 1, the dust suction structure 4 is used to absorb coal ash generated by the feeding belt 3 during the process of transporting coal, and the cleaning structure 5 is arranged in the shell 1 and can clean the coal attached to the feeding belt 3.

[0043] First of all, it should be noted that the transportation direction of coal refers to the direction from the feed port to the dust collection structure. For details, please refer to Figure 2 Direction of coal transportation shown.

[0044] In the above-mentioned coal feeding device, the coal can enter the shell 1 through the feeding port and fall onto the feeding belt 3. The feeding belt 3 can drive the coal to move, thereby realizing the transportation of the coal.

[0045] In the above-mentioned coal feeding device, since the coal feeding device is provided with a shell 1 and the feeding belt 3 is arranged in the shell 1, in other words, the coal feeding device forms a relatively sealed space, and the coal ash generated during the transportation process can be blocked by the shell 1, and it is not easy to pollute the environment.

[0046] Through the above technical scheme, since the coal feeding device is provided with a dust suction structure 4, the dust suction structure 4 is adjacent to the feed port 2 and connected to the interior of the shell 1, and the dust suction structure 4 is used to absorb the coal ash generated by the feeding belt 3 during the transportation of coal. In this way, even if a large amount of coal ash is generated during the transportation of coal, the air with coal ash attached can be absorbed by the dust suction structure 4 when passing through the dust suction structure 4, and the coal ash will not be discharged into the atmospheric environment, which effectively reduces the pollution caused to the environment by coal during transportation, and has high environmental protection.

[0047] In addition, since the coal feeding device is also provided with a cleaning structure 5, and the cleaning structure 5 is arranged in the shell 1 and can clean the coal attached to the feeding belt 3, in this way, even if the coal adheres to the feeding belt 3 due to the high water content of the coal or other factors during transportation, the coal adhered to the feeding belt 3 can also be cleaned by the cleaning structure 5, which effectively avoids the situation where too much coal adheres to the feeding belt 3, causing the feeding belt 3 to fail to operate normally and the coal cannot be transported normally.

[0048] In order to prevent the coal from generating a large amount of coal ash due to the impact when the coal falls into the coal feeding device through the feed port 2, as an embodiment of the present disclosure, Figure 2As shown, the above-mentioned coal feeding device may further include a guide plate 6, the guide plate 6 is located in the shell 1, the first end of the guide plate 6 is connected to the inner wall of the shell 1 and is arranged near the feed port 2, the second end of the guide plate 6 is arranged above the feed belt 3, and the second end of the guide plate 6 is used to bend toward the transportation direction of the coal, and the dust suction structure 4 is arranged at the rear side of the feed port 2 along the transportation direction of the coal. Since one end of the guide plate 6 is connected to the inner wall of the shell 1 and is arranged near the feed port 2, and the second end of the guide plate 6 is arranged above the feed belt 3, the guide plate 6 can guide the coal that falls into the coal feeding device through the feed port 2, and the coal can fall on the feed belt 3 in sequence under the guiding action of the guide plate 6, and be transported by the feed belt 3 without falling around, and the efficiency of coal transportation is high.

[0049] In addition, since the second end of the guide plate 6 is bent toward the transportation direction of the coal, in other words, the guide plate 6 can be formed as an arc-shaped guide plate 6. The arc-shaped guide plate 6 can buffer the coal falling into the coal feeding device through the feed port 2. The impact force between the coal and the guide plate 6 is small, which helps to reduce the coal ash generated during the falling process of the coal.

[0050] In order to facilitate the coal to fall into the coal feeding device, optionally, as Figure 1 and Figure 2 As shown, the coal feeding device can also include a feeding structure 7, which includes a feeding pipe 71, a dust return pipe 72 and a feeding hopper 73. One end of the feeding pipe 71 is connected to the feeding port 2, and the other end of the feeding pipe 71 is connected to the feeding hopper 73. The feeding hopper 73 is gradually expanded in the direction away from the feeding pipe 71. A dust return port 11 is also provided on the shell 1. The dust return port 11 is used to be located on the rear side of the feeding port 2 along the coal transportation direction. The first end of the dust return pipe 72 is connected to the dust return port 11, and the second end of the dust return pipe 72 is connected to the feeding pipe 71, and the opening of the second end of the dust return pipe 72 is inclined toward the feeding port 2. Since the two ends of the feed pipe 71 are respectively connected to the feed port 2 and the feed hopper 73, and the feed hopper 73 is gradually expanded in the direction away from the feed pipe 71, in other words, the feed hopper 73 is formed into a funnel shape. The funnel-shaped feed hopper 73 can guide the coal into the coal feeding device through the feed pipe 71 and the feed pipe 71. The funnel-shaped feed hopper 73 can also be used to control the speed at which the coal falls into the coal feeding device, effectively avoiding the accumulation of coal on the feeding belt 3.

[0051] In addition, since a dust return port 11 is provided on the rear side of the feed port 2 along the coal transportation direction, the dust port is connected to the feed pipe 71 through a dust return pipe 72, and the opening of the second end of the dust return pipe 72 is inclined toward the feed port 2. In this way, even if the coal entering the coal feeding device from the feed port 2 produces fine coal dust and / or coal ash due to impact, the coal ash can return to the coal feeding device again through the dust return pipe 72, which will not cause pollution to the external environment on the one hand, and will not cause coal loss on the other hand.

[0052] Alternatively, if Figure 2 As shown, the coal feeding device further includes a first ash baffle 8, which is arranged in the shell 1, and is located at the rear side of the dust return port 11 along the coal transportation direction, one end of the first ash baffle 8 is connected to the inner wall of the shell 1, and the other end of the first ash baffle 8 is bent toward the direction close to the dust return port 11, and there is a gap between the first ash baffle 8 and the feeding belt 3. Since the first ash baffle 8 is arranged at the rear side of the dust return port 11 along the coal transportation direction, and the side of the first ash baffle 8 away from the shell 1 is bent toward the direction close to the dust return port 11, the first ash baffle 8 can guide the fine coal dust and / or coal ash generated when the coal falls from the feed port 2, so as to prevent the fine coal dust and / or coal ash from spreading everywhere and affecting the treatment effect of the coal ash.

[0053] In addition, since there is a gap between the first ash baffle 8 and the feeding belt 3, the first ash baffle 8 will not interfere with the normal transportation of coal on the feeding belt 3, effectively avoiding the situation where the coal is blocked by the first ash baffle 8 and the coal cannot be transported normally.

[0054] In order to further prevent the fine coal dust and / or coal ash from spreading around during coal transportation, thereby affecting the treatment effect of the coal ash, as an embodiment of the present disclosure, Figure 2 As shown, the coal feeding device further includes a plurality of second ash baffles 9 arranged at intervals along the direction of coal transportation, the plurality of second ash baffles 9 are all arranged in the shell 1, and the plurality of second ash baffles 9 are all used to be arranged at the rear side of the dust collecting structure 4 along the direction of coal transportation, the upper ends of the plurality of second ash baffles 9 are connected to the shell 1, the lower ends of the second ash baffles 9 extend toward the feeding belt 3, and there is a gap between the second ash baffles 9 and the feeding belt 3. Since the plurality of second ash baffles 9 are arranged at intervals along the direction of coal transportation, the plurality of second ash baffles 9 can all play a role in blocking fine coal dust and / or coal ash generated during the coal transportation process, and the fine coal dust and / or coal ash generated during the coal transportation process is not easy to spread around, which is conducive to improving the treatment effect of coal ash.

[0055] In addition, since there is a gap between the second ash baffle plate 9 and the feeding belt 3, the second ash baffle plate 9 will not interfere with the normal transportation of coal on the feeding belt 3, effectively avoiding the situation where the coal is blocked by the second ash baffle plate 9 and the coal cannot be transported normally.

[0056] The present disclosure does not limit the specific composition of the dust suction structure 4, as long as the dust suction structure 4 can process the gas discharged from the coal feeding device, thereby preventing the coal ash from being discharged into the external environment. As an embodiment of the present disclosure, Figure 2 and Figure 4 As shown, the dust suction structure 4 includes an exhaust fan 41, a dust suction pipeline 42 and an exhaust pipeline 43. One end of the dust suction pipeline 42 is connected to the interior of the housing 1, and the other end of the dust suction pipeline 42 is connected to the exhaust port of the exhaust fan 41. One end of the exhaust pipeline 43 is connected to the exhaust port of the exhaust fan 41, and the other end of the exhaust pipeline 43 is used to communicate with the external environment. In this way, the gas discharged from the coal feeding device is processed through the dust suction pipeline 42 and / or the exhaust pipeline 43, so that the coal ash attached to the gas can be adsorbed, effectively avoiding the coal ash being directly discharged into the external environment, which will cause pollution to the external environment.

[0057] The present disclosure does not limit how the dust collecting structure 4 specifically handles the attached coal ash in the gas discharged from the coal feeding device. As an implementation method of the present disclosure, Figure 2 and Figure 4 As shown, the dust suction pipeline 42 may also include a dust suction cover 44. The shell 1 is provided with a first dust discharge port 12. The dust suction cover 44 is arranged outside the shell 1 and covers the first dust discharge port 12. The dust suction structure 4 also includes a filter 45. The dust suction pipeline 42 is connected to the first dust discharge port 12 through the filter 45. The exhaust pipeline 43 is used to communicate with the external environment through an opening arranged on the dust suction cover 44. Since the dust suction pipeline 42 is connected to the first dust discharge port 12 through the filter 45, in other words, the gas discharged from the coal feeding device through the first dust discharge port 12 will first pass through the filter 45, and then be discharged through the dust suction pipeline 42 and the exhaust pipeline 43. The filter 45 can filter the coal ash attached to the gas, thereby processing the gas discharged from the coal feeding device.

[0058] At the same time, the filter element 45 arranged between the first dust exhaust port 12 and the dust suction pipeline 42 can also prevent coal ash and the like from entering the exhaust fan 41, effectively preventing coal ash in the gas discharged by the coal feeding device from entering the exhaust fan 41 and easily damaging the exhaust fan 41, thereby increasing the service life of the exhaust fan 41.

[0059] It should be noted that the present disclosure does not limit the specific composition of the cleaning structure 5, as long as the cleaning structure 5 can clean the feeding belt 3, as an embodiment of the present disclosure,Figures 2 to 6 As shown, the cleaning structure 5 includes a first cleaning component 51 and a second cleaning component 52. The first cleaning component 51 is used to be arranged at the rear side of the feeding belt 3 along the coal transportation direction, and the second cleaning component 52 is used to be arranged at the front side of the feeding belt 3 along the coal transportation direction. The first cleaning component 51 is used to scrape off the coal attached to the feeding belt 3, and the second cleaning component 52 is used to extract the coal ash adsorbed on the feeding belt 3. In other words, the first cleaning component 51 and the second cleaning component 52 can both clean the feeding belt 3. Even if there is residual coal attached to the feeding belt 3 after the first cleaning component 51 cleans the feeding belt 3, the residual coal can also be cleaned by the second cleaning component 52. The cleaning effect of the cleaning structure 5 is good, which effectively avoids the situation that too much coal adheres to the feeding belt 3, resulting in the feeding belt 3 being unable to operate normally and the coal being unable to be transported normally.

[0060] The present disclosure does not limit the specific structure of the first cleaning component 51. As an embodiment of the present disclosure, Figure 4 and Figure 5 As shown, the first cleaning assembly 51 includes a support column 511 and a scraper 512 mounted on the support column 511, and the scraper 512 is in sliding contact with the feeding belt 3 to scrape off the coal attached to the feeding belt 3. In this way, if there is coal attached to the feeding belt 3, the attached coal will be scraped off by the scraper 512 when passing through the scraper 512, thereby cleaning the feeding belt 3.

[0061] The present disclosure does not limit the specific structure of the second cleaning component 52. As an embodiment of the present disclosure, Figure 6 As shown, the second cleaning assembly 52 includes a dust collector 521, which is arranged above the feeding belt 3, the suction port of the dust collector 521 is arranged opposite to the feeding belt 3, and the discharge port 5211 of the dust collector 521 is penetrated through the housing 1. The dust collector 521 can clean the residual coal attached to the feeding belt 3, thereby improving the cleaning effect of the cleaning structure 5 on the feeding belt 3.

[0062] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0063] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0064] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
