Description

Technical Field

[0001] The invention relates to the technical field of boiler fuel transportation, and in particular to an industrial solid waste feeding system. Background Art

[0002] Industrial solid waste refers to the residual waste, scraps and scraps that cannot be used to process products in the process of manufacturing products in the footwear, knitting, clothing, embroidery and other enterprises. It is generally also called "corner waste", and its generation accounts for 30% to 40% of the total materials. The disorderly stacking of corner waste not only affects the image of the city, but also poses a fire hazard. Fire incidents in corner waste dumps are common, which pollutes the environment and causes economic losses. The corner waste such as waste textiles, sponges, plastics, and shoe scraps in industrial solid waste has a high calorific value. It can replace some natural fossil fuels in the cement and thermal power industries. The use of corner waste to prepare fuel saves coal while absorbing waste, which has good economic and environmental benefits. The fuel made from the above-mentioned corner waste has a lower carbon emission factor than fossil fuels, which is one of the effective measures for cement, thermal power and other industries to achieve carbon emission reduction.

[0003] In the relevant technologies, the utilization of solid alternative fuels in industries such as coal-fired boilers and cement kilns is still immature, especially in the discharge and furnace feeding stages. Due to the huge differences in specific gravity, bulk density, particle size, grindability, etc. between conventional fuels such as pulverized coal and leftover garbage, the original fuel delivery system of industrial kilns is difficult to directly transport solid waste, which also greatly limits the promotion and utilization of solid waste alternative fuels. In addition, there is also the risk of flue gas leakage in the boiler system during the transportation of industrial solid waste. Summary of the invention

[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figure 1-Figure 5 As shown, the industrial solid waste feeding system of the embodiment of the present invention includes: a storage tank 200, a first conveying component and a second conveying component 2.

[0031] The storage tank 200 is used to store industrial solid waste 100, and the storage tank 200 has a storage outlet for discharging the industrial solid waste 100 stored in the storage tank 200. The first conveying assembly includes a first conveying member 1 and a discharge chute 13, and the first conveying member 1 includes a first conveying body 11 and a conveying pressure plate 12. The first end of the first conveying body 11 is arranged adjacent to the storage outlet, so as to convey the industrial solid waste 100 discharged from the storage outlet to the discharge chute 13, and the second end of the first conveying body 11 is placed in the discharge chute 13, and the conveying pressure plate 12 is rotatably connected to the first conveying body 11. The first conveying body 11 is used to drive the conveying pressure plate 12 to move along the circumferential direction of the first conveying body 11, and the conveying pressure plate 12 is placed in the discharge chute 13, and the conveying pressure plate 12 is used to squeeze the industrial solid waste 100 in the discharge chute 13. The second conveying component 2 has a feed port and a discharge port. The feed port is connected to the discharge chute 13, and the discharge port is connected to the conveying main pipe 300 of the boiler. The second conveying component 2 is used to convey the industrial solid waste 100 discharged from the discharge chute 13 to the boiler for combustion through the conveying main pipe 300.

[0032] Specifically, Figure 1-Figure 4 As shown, the storage tank 200 is located above the first conveying assembly, and the storage outlet of the storage tank 200 is arranged correspondingly to the rear end of the first conveying body 11, so that the industrial solid waste 100 discharged from the storage outlet falls on the rear end of the first conveying body 11, so that the industrial solid waste 100 is transported to the lower material tank 13 by the first conveying body 11. The front end of the first conveying body 11 extends into the lower material tank 13 to prevent the industrial solid waste 100 from being affected by the outside and falling to the outside of the first conveying body 11 during the transportation process.

[0033] It is understandable that if Figure 1-Figure 4 As shown, during the rotation of the conveying pressing plate 12 with the first conveying body 11, the conveying pressing plate 12 located in the lower chute 13 can squeeze the industrial solid waste 100 in the lower chute 13 to prevent the industrial waste 100 from expanding around after falling into the lower chute 13. In addition, under the squeezing action of the conveying pressing plate 12, the industrial waste 100 can be more easily moved toward the second conveying assembly.

[0034] Preferably, as shown in the figure, the inclination angle of the front side wall of the chute 13 is smaller than the inclination angle of the rear side wall of the chute 13, so that the space in the chute 13 located in front of the first conveying body 11 is increased, thereby preventing the industrial solid waste 100 from being scattered when falling into the chute 13, thereby improving the conveying efficiency.

[0035] It should be noted that the first conveying body 11 can be a transmission device with a transmission function driven by a gear or a pulley, and the conveying platen 12 is connected to the transmission belt of the first conveying body 11, so that when the transmission belt of the first conveying body 11 rotates or moves, it can drive the conveying platen 12 to move. During the movement of the conveying platen 12, when passing through the industrial solid waste 100 in the discharge chute 13, it can apply pressure to the material under the driving action of gravity or other driving equipment. When the conveying platen 12 approaches the industrial solid waste 100, it starts to apply pressure to the material, pushing or squeezing the industrial waste 100 in the direction toward the second conveying component 2. Optionally, the shape and size of the conveying platen 12 are designed so that it can effectively grasp and push the solid waste, similar to the compaction effect of a drum roller on the ground. Optionally, the first conveying body 11 can be a chain conveyor.

[0036] In other words, the industrial solid waste feeding system of the embodiment of the present invention can use the conveying pressure plate to squeeze the industrial solid waste in the feeding chute after conveying the industrial solid waste to the feeding chute, so that the industrial solid waste in the feeding chute enters the second conveying component in a squeezed state, thereby enabling the industrial solid waste to be buffered in the feeding chute and prevent expansion, thereby ensuring that the industrial solid waste can smoothly enter the second conveying component through the feed port, thereby achieving the effect of preventing the feeding chute from being blocked.

[0037] In some embodiments, the first conveying body 11 includes a conveying drive member 111 and a conveyor belt 112. The conveyor belt 112 is connected to the conveying drive member 111 for conveying industrial solid waste 100 to the lower trough 13. The rear side wall of the lower trough 13 has an avoidance opening 131 so that the conveyor belt 112 can pass through the avoidance opening 131. The conveying pressure plate 12 is connected to the conveyor belt 112, and the conveying pressure plate 12 can also pass through the avoidance opening 131 as the conveyor belt 112 moves, so that the side wall of the avoidance opening 131 can scrape off the industrial solid waste 100 adhered to the conveying pressure plate 12.

[0038] Specifically, Figure 1-Figure 4 As shown, the conveyor belt 112 is arranged around the conveyor drive 111, and the conveyor drive 111 rotates to drive the conveyor belt 112 to rotate, thereby realizing the function of conveying industrial solid waste 100. The rear side wall of the feed chute 13 is provided with an avoidance opening 131, so that the conveyor belt 112 at the lower part can move through the avoidance opening 131.

[0039] It is understandable that if Figure 1-Figure 4 As shown, the conveying driving member 111 can rotate to drive the conveyor belt 112 to rotate in the counterclockwise direction. The conveying platen 12 located in the feeding chute 13 can gradually become vertical under the influence of gravity in the top-down direction, and the driving member of the conveyor belt 112 can squeeze the industrial solid waste 100 below it until the conveyor belt 112 brings the conveying platen 12 to the adjacent avoidance port 131, and the conveying platen 12 can break away from the contact with the industrial solid waste 100. Finally, the conveying platen 12 can pass through the avoidance port 131 as the conveyor belt 112 rotates, and the lower wall of the conveyor belt 112 can contact the wall of the avoidance port 131, so that the industrial solid waste 100 adhering to the conveying platen 12 can be scraped off by the wall of the avoidance port 131 to prevent the leakage of the industrial solid waste 100.

[0040] Optionally, the conveying platen 12 includes a platen body 121 and an extension 122, wherein the extension 122 is connected between the platen body 121 and the conveyor belt 112, and the extension 122 is rotatable relative to the platen body 121 and the conveyor belt 112. Figure 1-Figure 4 As shown, the extension portion 122 is connected between the pressure plate body 121 and the conveyor belt 112, and the two ends of the extension portion 122 are respectively connected to the pressure plate body 121 and the conveyor belt 112 in a hinged manner, so that when the conveying pressure plate 12 moves to the upper part of the conveyor belt 112 along with the conveyor belt 112, it is ensured that the pressure plate body 121 can be laid flat on the conveyor belt 112, thereby preventing the industrial solid waste 100 that falls on the conveyor belt 112 from being scattered on the outside of the conveyor belt 112 due to the existence of the conveying pressure plate 12.

[0041] Preferably, there are multiple conveying pressure plates 12, and the multiple conveying pressure plates 12 are arranged at intervals along the extension direction of the conveyor belt 112. Multiple conveying pressure plates 12 are arranged at intervals along the extension direction of the conveyor belt 112, which can more evenly squeeze the industrial solid waste 100 and reduce the blockage and adhesion of the material in the discharge chute 13.

[0042] In some embodiments, the cross-sectional area of ​​the feed chute 13 increases gradually from bottom to top. Figure 1-Figure 4 As shown, the upper opening of the feed chute 13 is larger than the lower opening, so that the space adjacent to the left end of the feed chute 13 and the first conveying member 1 is enlarged, ensuring the falling space of the industrial solid waste 100 during the conveying process, which helps to smoothly convey the industrial solid waste 100, especially when the industrial solid waste 100 enters the feed chute 13 from the storage trough 200, which can reduce the occurrence of congestion.

[0043] In some embodiments, the second conveying component 2 includes a second conveying member, which includes a connected first conveying section 21 and a buffer section 22. The feed port is located in the first conveying section 21 and is connected to the outlet of the discharge chute 13. The discharge port is located on the buffer section 22 and is connected to the conveying main pipe 300.

[0044] Specifically, Figure 1-Figure 4 As shown, the first conveying section 21 is connected to the outlet of the discharge chute 13 so that the industrial solid waste 100 can be transported to the buffer section 22 under the conveying action of the first conveying section 21 and enter the conveying main pipe 300 from the buffer section 22 .

[0045] It can be understood that the first conveying section 21, the buffer section 22 and the second conveying section 23 are connected in sequence from left to right, wherein the first conveying section 21, the buffer section 22 and the second conveying section 23 can be detachably connected by means of bolts or the like, so that if a conveying failure occurs during use, they can be quickly disassembled and repaired, thereby reducing the difficulty of repairing the second conveying component 2 after a failure.

[0046] It should be noted that the first conveying section 21 and the second conveying section 23 can convey the industrial solid waste 100 by means of screw conveying, belt conveying, vibration conveying, chain conveying, etc. Figure 4 As shown, the first conveying section 21 can transport the industrial solid waste 100 from left to right, while the second conveying section 23 can transport the industrial solid waste 100 from right to left.

[0047] That is to say, during the transportation of the first conveying section 21, the industrial solid waste 100 in the first conveying section 21 will gradually enter the conveying main pipe 300 through the buffer section 22 under the continuous driving action of the conveying equipment. When the conveying volume of the first conveying section 21 is large, part of the industrial solid waste 100 in the buffer section 22 will be pushed into the second conveying section 23 under the driving force of the subsequent industrial solid waste 100 in the first conveying section 21. Therefore, the second conveying section 23 is set at the right end of the buffer section 22, which can provide reverse thrust for the industrial solid waste 100 in the buffer section 22 when the conveying volume is large, thereby avoiding the phenomenon of industrial solid waste 100 being squeezed to death during the transportation process.

[0048] Optionally, the first conveying section 21, the buffer section 22 and the second conveying section 23 may be integrally formed, that is, the second conveying assembly is an integral device to ensure the overall sealing of the second conveying assembly and reduce the possibility of smoke leakage from the second conveying assembly into the air.

[0049] Preferably, the radial dimension of the buffer section 22 is greater than the radial dimension of the first conveying section 21. It can be understood that Figure 4 and Figure 5 As shown, in a plane orthogonal to the left and right directions, the cross-sectional area of ​​the buffer section 22 is greater than the cross-sectional area of ​​the first conveying section 21. When the conveying volume of the second conveying assembly 2 is large, the first conveying section 21 can convey the industrial solid waste 100 to the buffer section 22, and because the radial dimension of the buffer section 22 is greater than the radial dimension of the first conveying section 21, the buffer section 22 provides expansion space for the industrial solid waste 100, which facilitates the subsequent falling of the industrial solid waste 100 into the conveying main pipe 300. In other words, the buffer section 22 and the second conveying section 23 are arranged in sequence at the right end of the first conveying section 21, which can prevent the industrial solid waste 100 from not falling into the conveying main pipe in time due to the excessively fast conveying speed, thereby preventing the industrial solid waste 100 from being squeezed to death at the right end of the second conveying assembly 2.

[0050] Alternatively, if Figure 5 As shown, the cross-street area of ​​the buffer section 22 gradually increases from bottom to top, which further facilitates the industrial solid waste 100 in the buffer section 22 to fall into the conveying main pipe 300.

[0051] In some embodiments, the second conveying member also includes a second conveying section 23, which is connected to the buffer section 22 and is located on the side of the buffer section 22 away from the first conveying section 21. The first conveying section 21 and the second conveying section 23 are both provided with spiral conveying plates, and the spiral conveying plates 27 in the first conveying section 21 and the spiral conveying plates 27 in the second conveying section 23 have opposite rotation directions.

[0052] It is understandable that if Figure 1-Figure 5 As shown, in the first conveying section 21, the industrial solid waste 100 discharged from the discharge chute 13 can be conveyed to the buffer section 22 by the forward rotation of the spiral conveying piece, that is, the industrial solid waste 100 moves toward the buffer section 22 under the rotation and pushing action of the spiral conveying piece 27 in the first conveying section 21. During the process of the first conveying section 21, the industrial solid waste 100 is tightly filled around the spiral conveying piece 27 under the action of the extrusion force, that is, the industrial waste 100 tightly wraps the spiral conveying piece 27, forming a sealing effect, thereby reducing the space for gas (i.e., the flue gas flowing from the conveying main pipe 300 to the second conveying component) to pass through. In other words, when the spiral conveying piece 27 rotates, the industrial solid waste 100 produces a sealing effect in the process of moving with the spiral conveying piece 27, making it difficult for the polluted gas (i.e., the flue gas) to enter or escape from the first conveying section 21 through the spiral part.

[0053] Preferably, the second conveying assembly includes a conveying drive member and a conveying drive shaft 26, and the conveying drive member is connected to the conveying drive shaft 26 to drive the conveying drive shaft 26 to rotate. The conveying drive shaft 26 runs through the second conveying assembly in the left-right direction, and the spiral conveying piece 27 disposed in the first conveying section 21 is connected to the conveying drive shaft 26 by welding, and the spiral conveying piece 27 disposed in the second conveying section 23 is connected to the conveying drive shaft 26 by welding.

[0054] In addition, if Figure 4 As shown, the conveying drive shaft 26 placed in the buffer section 22 adopts a smooth axis treatment, which can further expand the expansion space at the discharge port, making it easier for the industrial solid waste 100 to fall toward the conveying main pipe 300.

[0055] It should be noted that the flue gas in the conveying main pipe 300 flows from left to right, resulting in a certain negative pressure in the conveying connection piece 25. Under the action of this negative pressure, it is more conducive to the industrial solid waste 100 falling from the conveying connection piece 25 into the conveying main pipe 300.

[0056] Optionally, the second conveying member further includes a pressurizing member 24 , which has a pressurizing outlet connected to the buffer section 22 for introducing pressurized gas into the buffer section 22 .

[0057] It is understandable that if Figure 1-Figure 4As shown, the pressurizing member 24 can provide additional pressure during the transportation of the industrial solid waste 100, that is, when the pressurizing member 24 is working, it can pass high-pressure gas into the buffer section 22, so that the pressure of the discharge port adjacent to the side of the transportation main pipe 300 is greater than the pressure in the transportation main pipe 300, and further prevent the smoke in the transportation main pipe 300 from overflowing to the second transportation member. In addition, under the action of the high-pressure gas of the pressurizing member 24, the transportation of the industrial solid waste 100 to the transportation main pipe 300 is also facilitated, thereby improving the transportation efficiency.

[0058] It should be noted that the pressurizing member 24 can be a pneumatic conveying device such as a high-pressure air pump that can compress air to generate airflow. The arrangement of the pressurizing member 24 can generate pressurized gas and increase the driving force on the material in the buffer section 22, which helps the industrial solid waste 100 to move faster, especially when the industrial solid waste 100 is viscous or difficult to transport; of course, for industrial solid waste 100 with different characteristics, the pressure of the pressurized gas can be adjusted to meet different transportation requirements. In addition, the introduction of pressurized gas can be combined with an automated control system to achieve precise control of the transportation process.

[0059] In some embodiments, the second conveying member further includes a conveying connector 25, the first end of the conveying connector 25 is connected to the discharge port, the second end of the conveying connector 25 is connected to the conveying mother pipe 300, and the angle between the extending direction of the conveying connector 25 and the direction of material conveying in the conveying mother pipe 300 is less than Specifically, Figure 1-Figure 4 As shown, the angle between the extension direction of the conveying connector and the direction of material conveying in the conveying main pipe is , then, it is more convenient to transport the industrial solid waste in the buffer section through the connector, and It can also reduce the impact force of industrial solid waste when it enters the main conveying pipe, reduce damage to the main conveying pipe, and improve conveying efficiency.
