Description

Technical Field

[0001] The present invention belongs to 7.1 High-efficiency energy-saving industries under 7.1.1 High-efficiency energy-saving boilers and kilns in the catalogue of strategic emerging industries, 7 energy-saving and environmental protection industries, and relates to the field of combustion equipment, and specifically to a pre-combustion furnace fuel ton bag transportation system and a ton bag transportation and crushing method. Background Art

[0002] In order to meet the dual carbon goals, namely carbon peak and carbon neutrality, the decomposition furnace in thermal equipment is required to reduce the carbon content of combustion, that is, reduce the use of fuel: pulverized coal, and advocate the use of alternative fuels. An opening is opened on the side of the decomposition furnace to connect the precombustion furnace. A stepped structure is set up in the precombustion furnace. The alternative fuel goes down the steps step by step, is fully burned, and finally enters the decomposition furnace.

[0003] Pre-combustion furnaces are generally erected at high places. To deliver fuel to the pre-combustion furnace's feeding system, alternative fuels are often transported to a high position via a belt conveyor and then fed into the pre-combustion furnace through the feeding system. The disadvantage is that a considerable portion of the alternative fuel is composed of garbage. Continuous transportation in an exposed environment will cause unpleasant odors in the workplace and cause pollution.

[0004] The applicant has proposed CN2023229349617, a pre-combustion furnace fuel delivery system, which proposes that the alternative fuel be sealed during transportation, and the seal be broken when feeding into the pre-combustion furnace, so as to reduce the exposure of the alternative fuel to the external environment and reduce pollution. During transportation, the alternative fuel is carried by a transport cart throughout the process and lifted to the high feed port by a hoist for unloading. After further improvements, CN2023232362034 was proposed, replacing some of the transportation scenes with roller transportation, which improved the overall transportation environment, but still has not formed a complete and feasible transportation plan, so it needs to be further improved and a corresponding complete transportation method should be formed.

The fuel is packed in ton bags 4 and the ton bags 4 are transported to the plant 8 for storage; S2, transfer the ton bag 4 in the plant 8 to the rear end of the first roller conveyor system 81, and transport it to the front end along with the first roller conveyor system 81. After the first grating 811 detects the ton bag 4, it sends a command to the main controller to stop the first roller conveyor system 81; S3, the transport trolley 5 moves toward the first roller conveyor system 81 through the track 51, and the first in-position switch 511 sends a command to the main controller after detecting that the transport trolley 5 is in position, so that the transport trolley 5 stops, and the second roller conveyor system 52 on the transport trolley 5 abuts against the first roller conveyor system 81; S4, the first roller conveyor system 81 and the second roller conveyor system 52 operate synchronously, so that the ton bag 4 is moved to the second roller conveyor system 52, and the lever motor 53 operates synchronously, so that the lever 531 is raised to form a limit position. After the second grating 521 detects the ton bag 4, the second roller conveyor system 52 stops, and the transport trolley 5 operates and moves toward the elevator 3; the first roller conveyor system 81 executes S2; S5, after the deceleration switch 513 detects that the transport trolley 5 is in place, the transport trolley 5 decelerates, and after the second in-place switch 512 detects that the transport trolley 5 is in place, the transport trolley 5 stops, and the gear lever motor 53 runs to lower the gear lever 531; S6, the second roller conveyor system 52 and the third roller conveyor system 32 operate synchronously, so that the ton bag 4 moves to the third roller conveyor system 32.

[0021] As attached Figure 1-7As shown, a pre-combustion furnace fuel ton bag transportation system includes a pre-combustion furnace 1, the pre-combustion furnace 1 is fed by a feeding system 2, and a crushing and dropping mechanism 7 is arranged on the upper end of the feeding system 2. The crushing and dropping mechanism 7 can be a double-roller or multi-roller crusher in the prior art, but preferably a special crushing and dropping mechanism 7 of the present application described later, and also includes a hoist 3, a liftable car 31 is arranged on the hoist 3, the hoist 3 and the car 31 are the prior art and are not repeated here, a third roller conveying system 32 is arranged in the car 31, and a fourth roller conveying system 6 is arranged between the top of the hoist 3 and the crushing and dropping mechanism 7; and also includes a transport for transporting ton bags 4. The transport trolley 5 is provided with a second roller conveyor system 52, the roller conveyor system is the prior art, and preferably includes a frame for fixing, a plurality of rollers are arranged in an array on the frame, the rollers are rotatably connected to the frame, and a driven sprocket is fixed to one end of the roller; the frame is fixedly connected to the motor, the output end of the motor is connected to the input end of the reducer, the output end of the reducer is fixedly connected to the driving sprocket, the driving sprocket and the driven sprocket are connected in series through a chain, so that the roller is driven to rotate by the motor, and it can also be other roller structures in the prior art; the above-mentioned transportation system structure is detailed in CN2023229349617 and CN2023232362034.

[0022] As attached Figure 1-3 As shown, it also includes a track 51 that cooperates with the transport trolley 5. One end of the track 51 extends to the entrance of the car 31 at the bottom of the elevator 3. The other end of the track 51 is provided with a first roller conveyor system 81. The first roller conveyor system 81 is arranged in the factory building 8. Since the ton bag 4 contains flammable alternative fuel, the ton bag 4 is first transported to the factory building 8 for storage after packaging. An entrance is arranged at the rear of the factory building 8 for the ton bag 4 to be transported in, and an exit is arranged in the front of the factory building 8 for the track 51 to pass through. The walls and the top of the factory building 8 are preferably in a closed state, and the window part is provided with translucent shading glass. The factory building 8 is constructed with a crane or a small crane for lifting the ton bag 4, which is used to transfer the stored ton bag 4 to the tail end of the first roller conveyor system 81; a transfer node is formed between every two independent conveying systems, and an in-place detection mechanism is arranged around the transfer node. All in-place detection mechanisms and the driving mechanisms of all conveying systems are communicatively connected to the main controller, which can be a wired connection, but considering that the total volume is too large, a wireless connection is preferably preferred.

[0023] The testing agencies in place include the following: As attached Figure 4 As shown, first gratings 811 are arranged on both sides of the front end of the first roller conveyor system 81 , and a first in-position switch 511 is arranged on the track 51 in front of the front end of the first roller conveyor system 81 .

[0024] As attached Figure 5As shown, second gratings 521 are arranged on both sides of the front end of the second roller conveyor system 52, and the second gratings 521 are fixed on both sides of the transport trolley 5. A gear lever motor 53 is fixed on the front end of the transport trolley 5, and the output end of the gear lever motor 53 is fixedly connected to a gear lever 531. The gear lever 531 is located in front of the front end of the second roller conveyor system 52. With the rotation of the output end of the gear lever motor 53, the gear lever 531 is higher or lower than the load-bearing plane of the second roller conveyor system 52. The gear lever 531 is used to prevent the ton bag 4 from sliding forward out of the transport trolley 5 due to inertia when the transport trolley 5 decelerates during transportation. Preferably, a gear lever motor 53 and a gear lever 531 are also arranged at the rear of the transport trolley 5.

[0025] As attached Figure 6 As shown, a second in-position switch 512 is provided on the track 51 at the rear of the bottom of the elevator 3, and a deceleration switch 513 is provided on the track 51 at a distance of 3m~8m from the bottom of the elevator 3; a third grating 321 is provided on both sides of the front end of the third roller conveyor system 32; when the transport trolley 5 goes to the first roller conveyor system 81, it is in an unloaded state, so only the first in-position switch 511 is provided, and the transport trolley 5 can be stopped + braked after it is in position, but when the transport trolley 5 goes to the elevator 3, it carries a ton bag 4 weighing about 1 ton and outputs more power at the same time, so it is necessary to brake and decelerate in advance, so a deceleration switch 513 is provided at a distance of 3m~8m from the bottom of the elevator 3, and when the transport trolley 5 is detected, the main controller issues a brake deceleration command to stop at the position of the second in-position switch 512.

[0026] As attached Figure 7 As shown, the fourth roller conveyor system 6 includes a waiting section 61 that cooperates with the car 31 at the top of the elevator 3, and a continuous feeding section 62 for feeding materials to the crushing and dropping mechanism 7. The waiting section 61 and the continuous feeding section 62 operate independently. Independent operation means that they are respectively driven by two sets of drive motors and matching chain transmissions. The continuous feeding section 62 and the waiting section 61 are connected end to end but have no driving relationship. Fourth gratings 611 are set on both sides of the waiting section 61.

[0027] As for the ton bag crushing and dropping mechanism 7, CN2023229349617 and CN2023232362034 both record that a double-roller or multi-roller crusher in the prior art is used. The disadvantage is that the entire ton bag 4 and the fuel therein directly fall into the feeding system 2 below, resulting in material piling and jamming. Further, it may also cause hot air to return from the pre-combustion furnace 1 to the feeding system 2 and accumulate in the feeding system 2, and there is a risk of fuel burning in the feeding system 2. Therefore, improvements are made to change the material dropping of the crushing and dropping mechanism 7 from a one-time process to a continuous process.

[0028] As attached Figure 7-10As shown, a pre-combustion furnace fuel ton bag crushing and dropping mechanism includes a shell 71, an opening 72 is formed on one side of the shell 71, two crushing rollers 73 are arranged in the shell 71 at the opening 72, and the rotation direction of the crushing roller 73 is from between the two crushing rollers 73, to the direction toward the outside of the opening 72, that is, it is pushed out from the middle to the outside; a transportation mechanism for feeding materials in the direction of the crushing roller 73 is arranged outside the opening 72; a barb structure 74 is arranged on the opening 72 to prevent materials from moving away from the crushing roller 73.

[0029] The continuous feeding section 62 is made to run continuously. When there is no ton bag 4 on the continuous feeding section 62, the waiting section 61 runs to move the ton bag 4 to the continuous feeding section 62. The continuous feeding section 62 continuously provides a force to push the ton bag 4 into the crushing roller 73. The crushing roller 73 crushes the surface of the ton bag 4 and provides a force to push the ton bag 4 outward. The barb structure 74 scratches the surface of the ton bag 4 when the ton bag 4 enters, and when the crushing roller 73 pushes the ton bag 4 outward, the ton bag 4 is stuck. The ton bag 4 continues to leak material to the feeding system 2 through the surface break until there is not much remaining material and it is completely broken by the crushing roller 73 and falls into the feeding system 2 Furthermore, the crushing roller 73 is provided with crushing teeth 731, and the crushing teeth 731 of the two crushing rollers 73 are arranged alternately, and the crushing teeth 731 form a blade on one side of the rotating direction of the crushing roller 73, preferably forming a crescent blade shape as shown in the figure.

[0030] The transport mechanism is a continuous feeding section 62, which includes a plurality of rollers. A friction belt 621 is provided on the continuous feeding section 62. The friction belt 621 covers the roller closest to the opening 72 and at least one roller behind the roller. An anti-slip structure is provided on the friction belt 621. The anti-slip structure may be a rough surface of the friction belt 621 itself, or a plurality of transverse linear anti-slip patterns, wavy anti-slip patterns, or other shapes of anti-slip patterns are provided on the surface of the friction belt 621 along the transport direction.

[0031] Further, as attached Fig.10 As shown, the barb structure 74 includes a mounting seat 741, which is fixedly connected to the inner wall of the opening 72. The mounting seat 741 is hinged to the swing seat 742 through a rotating shaft. The end of the swing seat 742 away from the crushing roller 73 forms a hinge point. A torsion spring 743 is arranged outside the rotating shaft. The torsion spring 743 provides a force to swing the swing seat 742 outward. The swing seat 742 is fixedly connected to a blade 744. The side of the blade 744 away from the crushing roller 73 forms a cutting edge, and the side of the blade 744 close to the crushing roller 73 is a blunt end, so that the surface of the ton bag 4 is scratched when the ton bag 4 enters, and a hook is formed to clamp the ton bag 4 when the ton bag 4 is subjected to an outward force.

[0032] Preferably, a fixed blade 744 is provided at the bottom of the inner wall of the opening 72, preferably two blades 744 are provided on both sides, which also play a hanging role.

[0033] Furthermore, it also includes a driving motor, the output end of the driving motor is fixedly connected to the driving sprocket, and the driving sprocket cooperates with the chain; one end of a crushing roller 73 passes through the side wall of the shell 71 and is fixedly connected to the driven sprocket, and the driven sprocket cooperates with the chain, and the other end of the crushing roller 73 passes through the side wall of the shell 71 and is fixedly connected to the first gear, and the end of the other crushing roller 73 passes through the side wall of the shell 71 and is fixedly connected to the second gear, and the first gear is meshed with the second gear.

[0034] Ton bag transportation crushing method, the method is: S1. The fuel is packed in ton bags 4 and the ton bags 4 are transported to the plant 8 for storage; S2, transfer the ton bag 4 in the plant 8 to the rear end of the first roller conveyor system 81, and transport it to the front end along with the first roller conveyor system 81. After the first grating 811 detects the ton bag 4, it sends a command to the main controller to stop the first roller conveyor system 81; S3, the transport trolley 5 moves toward the first roller conveyor system 81 through the track 51, and the first in-position switch 511 sends a command to the main controller after detecting that the transport trolley 5 is in position, so that the transport trolley 5 stops, and the second roller conveyor system 52 on the transport trolley 5 abuts against the first roller conveyor system 81; S4, the first roller conveyor system 81 and the second roller conveyor system 52 operate synchronously, so that the ton bag 4 is moved to the second roller conveyor system 52, and the lever motor 53 operates synchronously, so that the lever 531 is raised to form a limit position. After the second grating 521 detects the ton bag 4, the second roller conveyor system 52 stops, and the transport trolley 5 operates and moves toward the elevator 3; the first roller conveyor system 81 executes S2; S5, after the deceleration switch 513 detects that the transport trolley 5 is in place, the transport trolley 5 decelerates, and after the second in-place switch 512 detects that the transport trolley 5 is in place, the transport trolley 5 stops, and the gear lever motor 53 runs to lower the gear lever 531; S6, the second roller conveyor system 52 and the third roller conveyor system 32 operate synchronously, so that the ton bag 4 moves to the third roller conveyor system 32. After the third grating 321 detects the ton bag 4, the second roller conveyor system 52 and the third roller conveyor system 32 stop, the car 31 closes the door, moves upward through the hoist 3, and the transport trolley 5 executes S3; S7, the car 31 is lifted to the height corresponding to the fourth roller conveyor system 6, the car 31 opens its door, the third roller conveyor system 32 and the fourth roller conveyor system 6 operate synchronously, so that the ton bag 4 moves to the waiting section 61, and after the fourth grating 611 detects the ton bag 4, the third roller conveyor system 32 and the fourth roller conveyor system 6 stop, the car 31 closes its door, and moves downward through the hoist 3, and the ton bag 4 stays in the waiting section 61; S8, the continuous feeding section 62 runs continuously. When there is no ton bag 4 on the continuous feeding section 62, the waiting section 61 runs to move the ton bag 4 to the continuous feeding section 62. The continuous feeding section 62 continuously provides a force to push the ton bag 4 into the crushing roller 73. The crushing roller 73 crushes the surface of the ton bag 4 and provides a force to push the ton bag 4 outward. The barb structure 74 scratches the surface of the ton bag 4 when the ton bag 4 enters, and when the crushing roller 73 pushes the ton bag 4 outward, the ton bag 4 is stuck. The ton bag 4 continues to leak material to the feeding system 2 through the surface break until there is not much remaining material and it is completely broken by the crushing roller 73 and falls into the feeding system 2.
