Description

Technical Field

[0001] The invention belongs to the technical field of coal dropping pipes, in particular to a curved coal dropping pipe. Background Art

[0002] Coal drop pipe is a kind of equipment used in coal conveying system, which is widely used in thermal power plants, ports, coal dumping stations, coal washing plants and coal-fired industrial boilers. Its main function is to transport coal from high places or storage bins to low places or transportation machinery, such as belt conveyors.

[0003] As an important part of the coal transportation system, the design and maintenance of the coal drop pipe is crucial to ensure the normal operation of thermal power plants and other related industries. Through reasonable design and the use of wear-resistant materials, the service life of the coal drop pipe can be effectively extended and the maintenance cost can be reduced.

[0004] In the current existing technology, when using a straight and inclined coal drop pipe to transport coal blocks, the coal blocks will continuously hit the inner wall of the coal drop pipe as they fall, thereby generating a large amount of coal dust. When the coal dust flows out, it will float outside the coal drop pipe, causing waste while also affecting the health of the workers. At the same time, since the material enters in a straight line, it is easy to cause a large impact and wear on the pipeline lining.

[0005] To this end, the present invention provides a curved coal dropping pipe. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: the curved coal dropping pipe described in the present invention comprises a coal guiding pipe, a cover shell is arranged at the top of the coal guiding pipe, a coal guiding trough is arranged at the bottom of the coal guiding pipe, a frame plate is arranged at the top of the coal guiding trough, a feeder is fixedly installed on the top of the frame plate, one end of the feeder is placed inside the cover shell, a material transfer assembly is arranged inside the cover shell, the material transfer assembly comprises a material transfer block, the material transfer assembly is used to drive the material transfer block to receive and slide the coal delivered from the feeder, a sliding assembly is arranged inside the coal guiding pipe, the sliding assembly is used to drive the coal slid on the sliding assembly to be transported, and a confluence assembly is arranged at the bottom of the coal guiding pipe, the confluence assembly is used to drive the coal delivered from the sliding assembly to return;

[0008] By connecting the top of the coal guide pipe with the cover shell, and connecting the bottom of the coal guide pipe with the top of the feeder, when the two are connected, start the feeder on the top of the frame plate to operate, and the feeder transports the coal into the cover shell, and the coal flows into the coal guide pipe through the ferry assembly in the cover shell. When the coal flows into the cover shell, the ferry assembly distinguishes the coal through the ferry block, and distinguishes the smaller particles and charcoal ash in the coal from the coal, to prevent the coal from having a lot of ash when entering the coal guide pipe. Ash removal is performed from the inlet end, which plays a screening role and reduces the amount of charcoal ash when flowing out. When the coal enters the coal guide pipe, the sliding assembly in the coal guide pipe drives the coal material that slides on the ferry assembly for transportation, and finally flows out through the confluence assembly set at the bottom end of the coal guide pipe. When the coal passes through the confluence assembly, the confluence assembly concentrates the coal so that the coal appears as a point-by-point outflow when it flows out.

[0009] Preferably, the coal guide pipe includes a shell, and there are multiple shells. The outer walls of the multiple shells are fixedly installed with connecting plates, and nuts and bolts are arranged between every two connecting plates. The multiple coal guide pipes are connected and assembled by nuts and bolts to form a completed coal guide pipe. The inner diameter curvatures of the multiple shells are different. When the multiple shells are connected, the inner diameter curvatures of the multiple shells can form a fastest curve. Lining plates are arranged at the places where the coal flows pass. The lining plates are arranged inside the shells. The lining plates are directly connected to the tube wall of the shells through nuts. Nuts and bolts are used between the top of a shell at the top and the bottom of the cover shell. The bottom of a shell at the bottom end is connected to the top of the coal guide trough by nuts and bolts. Before use, multiple shells are matched in position to connect corresponding connection plates, and then multiple shells are connected by bolts and nuts to form a completed coal guide pipe. Since the coal guide pipe is too large, multiple shells are connected in sections to facilitate subsequent maintenance and replacement of spare parts. The interior of the coal guide pipe after assembly is curved, and a fastest curve can be formed by calculation to facilitate the sliding of coal inside it without hitting the inner wall of the coal guide pipe.

[0010] Preferably, the ferry assembly also includes a blowing device, which is fixedly installed on the top of the feeder, and an air flow duct is fixedly installed on the outer wall of the blowing device, and an air plate is fixedly installed on one end of the air flow duct, and the air outlet end face of the air plate is flush with the inner wall of the ferry block, and the ferry block is fixedly installed on the inner wall of the cover shell, and the inner wall of the ferry block is provided with a plurality of ash flow openings. When the coal enters the cover shell, the coal will fall downward from one end of the feeder. When the coal falls, the blowing device blows out wind from the air plate through the air flow duct, and the carbon ash in the coal can be separated from the coal through the falling trajectory of the coal and the blowing operation of the air plate. Before the coal enters the coal guide pipe, a ash removal operation is first performed on the coal itself to reduce the amount of coal ash generated in the coal guide pipe later, thereby playing the role of ash screening.

[0011] Preferably, a motor is fixedly installed on the outer wall of the feeder, and an ash box is fixedly installed on the bottom of the feeder, one end of the ash box is placed inside the cover shell, and one end of the ash box is fixedly connected to one side of the ferry block. The air outlet end face of the air plate, the opening position of the ash flow port and the position of the ash box at one end inside the cover shell have their center positions on the same horizontal line. When the coal ash is blown by the airflow, the coal ash enters the ash box at the bottom of the feeder from the ash flow port on the ferry block, and the screened coal ash is collected to facilitate subsequent processing and production of the coal ash, reduce waste of resources, and play a role in storing coal ash.

[0012] Preferably, the inner wall of the ferry block is symmetrically provided with coal collecting openings, and a scraper plate is fixedly installed on the top of the ferry block. The top of the scraper plate can be slidably connected to the outer wall of the conveyor belt in the feeder. When the conveyor belt in the feeder drives the coal to be transported, the scraper plate on one side of the ferry block continuously scrapes the conveyor belt to prevent the coal on the conveyor belt from falling incompletely. Residual coal is placed on the conveyor belt, which is not conducive to the transportation and falling of the coal, and plays the role of scraping the coal. When the coal falls, it will move downward along the coal collecting opening, so that the coal transported out of the feeder will gather and flow downward, preventing the coal from sliding down at will, and playing the role of avoiding the path.

[0013] Preferably, the sliding assembly includes an arc sliding block, the setting angle of the arc sliding block is maintained in the same state as the curvature of the inner diameter of the shell, a sliding groove is opened in the middle of the arc sliding block, the position of the sliding groove is consistent with the position of the coal collecting port, and the two have the same width, the top of the arc sliding block is fixedly connected to the bottom end of the ferry block, and the outer wall of the arc sliding block is plated with wear-resistant ceramics. When the coal passes through the coal collecting port and enters the arc sliding block, the coal continues to slide downward along the sliding groove in the arc sliding block. Through the setting of the fastest curve surface of the arc sliding block, the coal will slide downward through a curved path in the sliding groove, reducing the collision of the coal in the coal guide pipe, thereby reducing the coal ash generated by the impact of the coal, and playing the role of sliding the coal.

[0014] Preferably, a plurality of wind-slowing plates are fixedly installed on the inner wall of the coal guide pipe, and the wind-slowing plates are set at an inclined angle to maintain a horizontal state with the inner diameter of the arc slider. When the coal slides down, airflow will be generated, and the airflow will blow down along with the coal. At this time, a plurality of wind-slowing plates are set inside the coal guide pipe, which can block the airflow when the coal slides down, reduce the blowing of the airflow, and prevent the airflow from blowing up the coal ash attached to the coal when blowing downward, thereby playing a role of slowing the wind.

[0015] Preferably, the confluence assembly includes a coal collecting plate, and there are two coal collecting plates. The two coal collecting plates are symmetrically connected to the bottom end of the arc sliding block, and a confluence port is formed between the two coal collecting plates. A coal calibration plate is fixedly installed at the bottom end of the two coal collecting plates, and one end of the two coal calibration plates is placed inside the coal guide trough. When the coal slides along the sliding trough to the bottom end of the coal guide pipe, the coal will move downward along the opening between the two coal collecting plates, and finally fall into the coal guide trough through the coal calibration plates. The setting of the two coal collecting plates can limit the coal to flow out in a one-point manner when it falls out. The setting of the two coal calibration plates provides a limit for the coal when it falls, so as to prevent the coal from falling to both sides of the coal guide trough when it falls and not gathering in the center.

[0016] Preferably, the outer walls of the two coal collecting plates are slidably connected with a push plate, and the outer walls of the two coal collecting plates are slidably connected with a rectangular plate, a plurality of shaft rods are fixedly installed on one side of the two rectangular plates, and a push plate is fixedly installed on the top of the plurality of shaft rods, a plurality of return springs are arranged between the inner side of the rectangular plate and the bottom of the coal collecting plate, and the plurality of return springs are respectively placed on the outside of the plurality of shaft rods, and a machine control button is symmetrically fixedly installed on the outer wall of the coal collecting plate, and the positions of the two machine control buttons correspond to the positions of the two push plates. When the coal collecting plate is blocked, the coal will push the rectangular plate to move due to the accumulation of coal at the coal collecting plate, and when the rectangular plate moves, the rectangular plate pulls the push plate to squeeze the return spring to move, and when the push plate squeezes the machine control button, the machine control button controls the feeder to stop conveying, thereby automatically detecting the blockage.

[0017] Preferably, a shock box is fixedly installed on the outer wall of the coal guide pipe, a telescopic cylinder is fixedly installed on the inner wall of the shock box, and a shock coal block is fixedly installed on the output end of the telescopic cylinder. When the control button controls the feeder to stop conveying, the control button controls the telescopic cylinder in the shock box to push the shock coal block to operate, and the shock coal block will push the outer wall of the coal guide pipe, thereby shaking out the coal accumulated between the two coal collecting plates, thereby unblocking the coal collecting plates and playing a role of automatic unblocking.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The curved coal drop pipe described in the present invention distinguishes the coal through the ferry assembly through the ferry block, and distinguishes the smaller particles and charcoal ash in the coal from the coal, so as to prevent the coal from having a lot of ash on it when entering the coal guide pipe, and performs ash removal from the inlet end to reduce the amount of charcoal ash when flowing out. When the coal enters the coal guide pipe, the sliding assembly in the coal guide pipe drives the coal that is slid on the ferry assembly for transportation, and finally flows out through the confluence assembly arranged at the inner bottom end of the coal guide pipe. When the coal passes through the confluence assembly, the confluence assembly gathers the coal so that the coal flows out in a point-type manner.

[0020] 2. The curved coal drop pipe described in the present invention forms a complete coal guide pipe by pairing the positions of multiple shells to connect the corresponding connecting plates, and then connecting the multiple shells with bolts and nuts. Since the coal guide pipe is too large, multiple shells are connected in sections to facilitate subsequent maintenance and replacement of spare parts. The interior of the coal guide pipe after assembly is curved, and a fastest curve can be formed through calculation, which facilitates the sliding of coal inside the coal guide pipe without hitting the inner wall of the coal guide pipe.

[0021] 3. The curved coal dropping pipe described in the present invention, when the coal enters the cover, the coal will fall downward from one end of the feeder. When the coal falls, the blowing device blows out wind from the wind plate through the wind flow pipe. Through the falling trajectory of the coal and the blowing operation of the wind plate, the charcoal ash in the coal can be separated from the coal. Before the coal enters the coal guiding pipe, a ash removal operation is first performed on the coal itself to reduce the amount of coal ash generated in the coal guiding pipe later, thereby playing the role of ash screening.

[0022] 4. The curved coal drop pipe described in the present invention, when the coal collecting plate is blocked, the coal will push the rectangular plate to move due to the accumulation of coal at the coal collecting plate. When the rectangular plate moves, the rectangular plate pulls the push plate to squeeze the reset spring to move. When the push plate is squeezed to the machine control button, the machine control button controls the feeder to stop conveying. Then the machine control button controls the telescopic cylinder in the shock box to push the shock coal block to operate. The shock coal block will knock on the outer wall of the coal guide pipe, thereby shaking out the coal accumulated between the two coal collecting plates, thereby unblocking the coal collecting plates and playing a role of automatic blockage relief.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] like Figures 1 to 9 As shown, a curved coal drop pipe described in an embodiment of the present invention comprises a coal guide pipe 2, a cover shell 3 is arranged at the top of the coal guide pipe 2, a coal guide trough 1 is arranged at the bottom of the coal guide pipe 2, a frame plate 5 is arranged at the top of the coal guide trough 1, a feeder 4 is fixedly installed on the top of the frame plate 5, one end of the feeder 4 is placed inside the cover shell 3, a material transfer assembly is arranged inside the cover shell 3, the material transfer assembly comprises a material transfer block 7, the material transfer assembly is used to drive the material transfer block 7 to receive and slide the coal transported from the feeder 4, a sliding assembly is arranged inside the coal guide pipe 2, the sliding assembly is used to drive the coal transported by the sliding assembly, and a confluence assembly is arranged at the bottom of the coal guide pipe 2, the confluence assembly is used to drive the coal transported from the sliding assembly to return;

[0036] When the coal blocks are transported by the vertical inclined coal drop pipe, the falling coal blocks will hit the inner wall of the coal drop pipe, thereby generating a large amount of coal dust. When the coal dust flows out, it will float outside the coal drop pipe in a flying shape, causing waste and affecting the health of workers;

[0037] The top of the coal guide pipe 2 is connected to the cover shell 3, and the bottom of the coal guide pipe 2 is connected to the top of the feeder 4. When the connection between the two is completed, the feeder 4 on the top of the frame plate 5 is started to operate. The feeder 4 transports the coal into the cover shell 3, and the coal flows into the coal guide pipe 2 through the ferry assembly in the cover shell 3. When the coal flows into the cover shell 3, the ferry assembly distinguishes the coal through the ferry block 7, and distinguishes the smaller particles and charcoal ash in the coal from the coal, so as to prevent the coal from having a lot of ash on it when entering the coal guide pipe 2. The ash removal operation is performed from the inlet end, which plays a screening role and reduces the charcoal ash when it flows out. When the coal enters the coal guide pipe 2, the sliding material component in the coal guide pipe 2 drives the coal material slid on the transfer material component for transportation, and finally flows out through the merging component arranged at the bottom end of the inner part of the coal guide pipe 2. When the coal passes through the merging component, the merging component concentrates the coal so that the coal presents a point-by-point outflow when it flows out. It should be noted here that the speed ratio between the outflow speed of the coal in the coal guide pipe 2 and the guiding speed in the coal guide trough 1 needs to be adjusted and calculated according to the actual length of the coal guide pipe 2, so that when the coal flows out through the merging component, it falls into the coal guide trough 1 in a flushing manner instead of falling into the inside of the coal guide trough 1 in an impact manner.

[0038] like Figure 6 to Figure 7 As shown, the coal guide pipe 2 includes a shell 207, and there are multiple shells 207. The outer walls of the multiple shells 207 are fixedly installed with connecting plates 202. Nuts 203 and bolts 204 are arranged between every two connecting plates 202. The multiple coal guide pipes 2 are connected and assembled by nuts 203 and bolts 204 to form a completed coal guide pipe 2. The inner diameters of the multiple shells 207 have different curvatures. When the multiple shells 207 are connected, the inner diameters of the multiple shells 207 can form a fastest curve. Liners are arranged at the places where the coal flows pass. The liner is arranged inside the shell 207. The liner is directly connected to the tube wall of the shell 207 through nuts 203. The top of a shell 207 at the top is connected to the bottom of the cover shell 3 by nuts 203 and bolts 204. The bottom of a shell 207 at the bottom is also connected to the top of the coal guide trough 1 by nuts 203 and bolts 204.

[0039] Before use, multiple shells 207 are matched in position to connect the corresponding connection plates 202, and then the multiple shells 207 are connected using bolts 204 and nuts 203 to form a completed coal guide pipe 2. Since the coal guide pipe 2 is too large, multiple shells 207 are connected in sections to facilitate subsequent maintenance and replacement of spare parts. The interior of the coal guide pipe 2 after assembly is curved, and a fastest curve can be formed by calculation, which is convenient for coal to slide inside without hitting the inner wall of the coal guide pipe 2. It should be noted that the shell 207 is made of Q235B The material is made of 8mm thick. All the straight sections of the shell 207 are designed as wear surfaces, the oblique sections are designed as non-wear surfaces, and the others are designed as wear surfaces. The non-wear surface is made of 10mm thick Q235B material, and the wear surface is made of bimetallic high-chromium alloy wear-resistant plate. The bimetallic high-chromium alloy wear-resistant plate is a 10mm Q235 ordinary steel plate with a 10mm thick high-chromium bimetallic cladding wear-resistant composite steel plate. The total thickness is ≤20mm. The surface hardness of the composite plate is HC55-60, and the chromium content exceeds 32%. The fastest curve refers to the curve between two points that takes the shortest time for an object to move along it. This curve is usually called a cycloid or a cycloid. Its shape makes the object accelerate nearly vertically at the initial stage, so that it can complete the movement at a faster average speed in the subsequent stage, and finally reach the end point in the shortest time.

[0040] like Figures 3 to 5 As shown, the material transfer assembly also includes a blowing device 6, which is fixedly installed on the top of the feeder 4, and a wind pipe 602 is fixedly installed on the outer wall of the blowing device 6, and a wind plate 601 is fixedly installed on one end of the wind pipe 602, and the wind outlet end surface of the wind plate 601 is flush with the inner wall of the material transfer block 7, and the material transfer block 7 is fixedly installed on the inner wall of the housing 3, and a plurality of ash flow openings 701 are opened on the inner wall of the material transfer block 7;

[0041] When the coal enters the cover 3, the coal will fall downward from one end of the feeder 4. When the coal falls, the blowing device 6 blows out wind from the wind plate 601 through the wind pipe 602. Through the falling trajectory of the coal and the blowing operation of the wind plate 601, the carbon ash in the coal can be separated from the coal. Before the coal enters the coal guide pipe 2, a ash removal operation is performed on the coal itself to reduce the amount of coal ash generated in the coal guide pipe 2 later, thereby playing the role of ash screening.

[0042] like Figure 3 to Figure 4 As shown, a motor 401 is fixedly installed on the outer wall of the feeder 4, an ash box 10 is fixedly installed on the bottom of the feeder 4, one end of the ash box 10 is placed inside the housing 3, one end of the ash box 10 is fixedly connected to one side of the material transfer block 7, and the air outlet end surface of the air plate 601, the opening position of the ash flow port 701 and the position of the ash box 10 at one end inside the housing 3, the three center positions are on the same horizontal line;

[0043] When the coal ash is blown by the air flow, the coal ash enters the ash box 10 at the bottom of the feeder 4 from the ash flow port 701 on the ferry block 7, and the screened coal ash is collected to facilitate subsequent processing and production of the coal ash, reduce the waste of resources, and play the role of storing coal ash.

[0044] like Figures 4 to 5 As shown, the inner wall of the ferry block 7 is symmetrically provided with coal receiving openings 702, and a scraper plate 703 is fixedly installed on the top of the ferry block 7, and the top of the scraper plate 703 can be slidably connected to the outer wall of the conveyor belt in the feeder 4;

[0045] When the conveyor belt in the feeder 4 drives the coal to be transported, since the scraper plate 703 is arranged on one side of the ferry block 7, when the conveyor belt in the feeder 4 continues to transport the coal, the scraper plate 703 continues to scrape the conveyor belt to prevent the coal on the conveyor belt from falling incompletely. Residual coal is placed on the conveyor belt, which is not conducive to the transportation and falling of the coal, and plays the role of scraping the coal. When the coal falls, it will move downward along the coal collection port 702, so that the coal transported from the feeder 4 will gather and flow downward, preventing the coal from sliding down at will, and playing the role of avoiding the path. It should be noted here that an ash drop port should be left between the feeder 4 and the rectangular plate 8, and the coal ash placed on the conveyor belt will enter the ash box 10 along the ash drop port when reciprocating.

[0046] like Figure 6 to Figure 7 As shown, the sliding material assembly includes an arc sliding block 201, the setting angle of the arc sliding block 201 is kept in the same state as the inner diameter curvature of the shell 207, a sliding material groove 205 is opened in the middle of the arc sliding block 201, the position of the sliding material groove 205 is consistent with the position of the coal collecting port 702, and the two have the same width, the top end of the arc sliding block 201 is fixedly connected to the bottom end of the ferry block 7, and the outer wall of the arc sliding block 201 is plated with wear-resistant ceramics;

[0047] When the coal enters the arc slide block 201 through the coal collecting port 702, the coal continues to slide downward along the slide groove 205 in the arc slide block 201. Through the setting of the fastest curve surface of the arc slide block 201, the coal will slide downward through the curved path in the slide groove 205, reducing the collision of the coal in the coal guide pipe 2, thereby reducing the coal ash generated by the impact of the coal, and playing the role of sliding the coal. It should be noted here that the arc slide block 201 should be an assembled slide block.

[0048] like Figure 6 to Figure 7 As shown, a plurality of air slowing plates 206 are fixedly installed on the inner wall of the coal guide pipe 2, and the air slowing plates 206 are set at an inclined angle to maintain a horizontal state with the inner diameter of the arc slider 201;

[0049] When the coal is sliding down, airflow will be generated, and the airflow will blow down along with the coal. At this time, a plurality of slow-wind plates 206 are arranged inside the coal guide pipe 2, which can block the airflow when the coal is sliding down, reduce the blowing of the airflow, and prevent the airflow from blowing up the coal ash attached to the coal when blowing down, thereby playing the role of slowing the wind.

[0050] like Figures 7 and 8 As shown, the confluence assembly includes a coal collecting plate 801, and there are two coal collecting plates 801. The two coal collecting plates 801 are symmetrically connected to the bottom end of the arc slider 201, and a confluence port is formed between the two coal collecting plates 801. The bottom ends of the two coal collecting plates 801 are fixedly installed with coal calibration plates 802, and one end of the two coal calibration plates 802 is placed inside the coal guide trough 1;

[0051] When the coal slides along the slide chute 205 to the bottom end of the coal guide pipe 2, the coal will move down along the opening between the two coal collecting plates 801, and finally fall into the coal guide chute 1 through the coal calibration plate 802. The setting of the two coal collecting plates 801 can limit the coal from flowing out in a single point when falling out, and the setting of the two coal calibration plates 802 provides a limit for the coal when falling, preventing the coal from falling to both sides of the coal guide chute 1 when falling and not gathering in the center.

[0052] like Figures 8 to 9 As shown, the outer walls of the two coal collecting plates 801 are slidably connected with push plates 803, the outer walls of the two coal collecting plates 801 are slidably connected with rectangular plates 8, one side of the two rectangular plates 8 is fixedly installed with multiple shafts 805, the tops of the multiple shafts 805 are fixedly installed with push plates 803, multiple reset springs 806 are arranged between the inner side of the rectangular plate 8 and the bottom of the coal collecting plate 801, and the multiple reset springs 806 are respectively placed outside the multiple shafts 805, and the outer walls of the coal collecting plates 801 are symmetrically fixedly installed with control buttons 804, and the positions of the two control buttons 804 correspond to the positions of the two push plates 803;

[0053] When the coal collecting plate 801 is blocked, the coal will push the rectangular plate 8 to move due to the accumulation of coal on the coal collecting plate 801. When the rectangular plate 8 moves, the rectangular plate 8 pulls the push plate 803 to squeeze the return spring 806 to move. When the push plate 803 squeezes the control button 804, the control button 804 controls the feeder 4 to stop conveying, thereby automatically detecting blockage.

[0054] like Figures 8 to 9 As shown, a material-vibrating box 9 is fixedly installed on the outer wall of the coal-conducting pipe 2, a telescopic cylinder 901 is fixedly installed on the inner wall of the material-vibrating box 9, and a coal-vibrating block 902 is fixedly installed on the output end of the telescopic cylinder 901;

[0055] When the control button 804 controls the feeder 4 to stop conveying, the control button 804 controls the telescopic cylinder 901 in the shock box 9 to push the shock coal block 902 to operate, and the shock coal block 902 will push the outer wall of the coal guide pipe 2, thereby shaking out the coal accumulated between the two coal collecting plates 801, thereby unblocking the coal collecting plates 801 and playing a role of automatic unblocking.

[0056] Working principle: by connecting the top end of the coal guide pipe 2 with the cover shell 3, and connecting the bottom end of the coal guide pipe 2 with the top of the feeder 4, when the two are connected, start the feeder 4 on the top of the frame plate 5 to operate, and the feeder 4 transports the coal into the cover shell 3, and flows into the coal guide pipe 2 through the ferry assembly in the cover shell 3. When the coal flows into the cover shell 3, the ferry assembly distinguishes the coal through the ferry block 7, and distinguishes the smaller particles and charcoal ash in the coal from the coal, so as to prevent the coal from having a lot of ash on it when entering the coal guide pipe 2. The ash removal operation is performed from the inlet end, which plays a screening role and reduces the amount of charcoal ash when flowing out. When the coal enters the coal guide pipe 2, the sliding assembly in the coal guide pipe 2 drives the coal material slid on the ferry assembly for transportation, and finally flows out through the confluence assembly arranged at the bottom end of the coal guide pipe 2. When the coal passes through the confluence assembly, the confluence assembly gathers the coal so that the coal flows out in a point-like manner.

[0057] Before use, multiple shells 207 are matched in position to connect corresponding connection plates 202, and then multiple shells 207 are connected using bolts 204 and nuts 203 to form a completed coal guide pipe 2. Since the size of the coal guide pipe 2 is too large, multiple shells 207 are connected in sections to facilitate subsequent maintenance and replacement of spare parts. The interior of the assembled coal guide pipe 2 is curved, and a fastest curve can be formed by calculation, which is convenient for coal to slide inside without hitting the inner wall of the coal guide pipe 2.

[0058] When the coal enters the housing 3, the coal will fall downward from one end of the feeder 4. When the coal falls, the blowing device 6 blows out wind from the air plate 601 through the air flow pipe 602. Through the falling trajectory of the coal, the blowing operation of the air plate 601 can separate the charcoal ash from the coal. Before the coal enters the coal guide pipe 2, a ash removal operation is first performed on the coal itself, reducing the amount of ash generated in the coal guide pipe 2 later, which plays the role of ash screening.

[0059] When the coal ash is blown by the airflow, the coal ash enters the ash receiving box 10 at the bottom of the feeder 4 from the ash flow port 701 on the ferry block 7, and the screened coal ash is collected to facilitate the subsequent processing and production of the coal ash, reduce the waste of resources, and play the role of storing coal ash;

[0060] When the conveyor belt in the feeder 4 drives the coal to be transported, the scraper plate 703 on one side of the ferry block 7 continuously scrapes the conveyor belt to prevent the coal on the conveyor belt from falling incompletely. Residual coal is placed on the conveyor belt, which is not conducive to the transportation and falling of the coal, and plays the role of scraping the coal. When the coal falls, it moves downward along the coal collection port 702, so that the coal transported from the feeder 4 is gathered and flows downward, preventing the coal from sliding down randomly, and playing the role of avoiding the path;

[0061] When the coal enters the arc slide block 201 through the coal collecting port 702, the coal continues to slide downward along the slide groove 205 in the arc slide block 201. Through the setting of the fastest curve surface of the arc slide block 201, the coal will slide downward in the slide groove 205 through a curved path, reducing the collision of the coal in the coal guide pipe 2, thereby reducing the coal ash generated by the collision of the coal, and playing the role of sliding the coal;

[0062] When the coal is sliding down, airflow will be generated, and the airflow will blow down along with the coal. At this time, a plurality of slow-wind plates 206 are arranged inside the coal guide pipe 2, so that the coal can block the airflow when it is sliding down, reduce the blowing of the airflow, and prevent the coal ash attached to the coal from being blown up when the airflow blows down, thus playing the role of slowing down the airflow.

[0063] When the coal slides along the sliding chute 205 to the bottom of the coal guide pipe 2, the coal will move down along the opening between the two coal collecting plates 801, and finally fall into the coal guide chute 1 through the coal calibration plate 802. The two coal collecting plates 801 are arranged to limit the coal from flowing out in a single point when falling out, and the two coal calibration plates 802 are arranged to provide a limit for the coal when falling, so as to prevent the coal from falling to both sides of the coal guide chute 1 when falling and not gathering in the center.

[0064] When the coal collecting plate 801 is blocked, the coal will push the rectangular plate 8 to move due to the accumulation of coal at the rectangular plate 801. When the rectangular plate 8 moves, the rectangular plate 8 pulls the push plate 803 to squeeze the return spring 806 to move. When the push plate 803 squeezes the control button 804, the control button 804 controls the feeder 4 to stop conveying, which plays the role of automatically detecting blockage.

[0065] When the control button 804 controls the feeder 4 to stop conveying, the control button 804 controls the telescopic cylinder 901 in the shock box 9 to push the shock coal block 902 to operate, and the shock coal block 902 will push the outer wall of the coal guide pipe 2, thereby shaking out the coal accumulated between the two coal collecting plates 801, thereby unblocking the coal collecting plates 801 and playing a role of automatic unblocking.
