[0021] The 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.

[0022] The waste conveying device according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0023] The waste conveying device of the embodiment of the present invention includes a silo 1 , a discharge pipe 2 , a feeding assembly 3 and a loosening assembly 4 .

[0024] The discharge pipe 2 is provided at the lower side of the silo 1 to transport the loose waste stored in the silo 1. The feeding assembly 3 is provided at the lower end of the silo 1 to transport the loose waste at the bottom end of the silo 1 to the discharge pipe 2 along the radial direction of the silo 1.

[0025] Specifically, the silo 1 extends in the up-down direction, the discharge pipe 2 extends in the horizontal direction, and an opening is provided at the lower end of the silo 1 to allow the textile waste in the silo 1 to be discharged from the silo 1 through the discharge pipe 2 .

[0026] The feeding assembly 3 is connected between the opening at the lower end of the silo 1 and the discharge pipe 2. The waste in the silo 1 falls to the feeding assembly 3 under the action of gravity. The feeding assembly 3 extends horizontally to move the waste falling on the bottom of the silo 1 horizontally into the discharge pipe 2.

[0027] The loosening component 4 is arranged on the inner wall of the silo 1 and is located on the upper side of the downstream end of the feeding component 3. The loosening component 4 is suitable for stirring the loose waste that moves with the feeding component 3 and accumulates on the inner wall of the silo 1 to prevent the loose waste accumulated on the inner wall of the silo 1 from blocking the feeding component 3.

[0028] Specifically, the feeding component 3 extends in the left-right direction to transport the waste at the bottom of the silo 1 from left to right, and the loosening component 4 is arranged on the inner wall of the right end of the silo 1. When the feeding component 3 transports the waste in the silo 1 to the right, the waste in the silo 1 is entangled with each other so that part of the waste is accumulated on the inner wall of the right end of the silo 1, blocking the waste at the right end of the silo 1 from falling, and the waste accumulated at the right end of the silo 1 involves the waste in the feeding component 3, which can easily cause the feeding component 3 to be blocked.

[0029] The loosening component 4 is arranged on the inner wall of the right end of the silo 1. When the feeding component 3 is running, the waste materials in the silo 1 are pulled together, and the waste materials in the feeding component 3 pull the waste materials in the silo 1, so that part of the waste materials are accumulated on the outer peripheral side of the loosening component 4. The loosening component 4 continuously stirs the waste materials around it to achieve the effect of stirring and loosening the waste materials accumulated on the inner wall of the right end of the silo 1, thereby avoiding the accumulation of waste materials on the inner wall of the silo 1.

[0030] The waste conveying device of the embodiment of the present invention is provided with a loosening component 4 in the silo 1. When the feeding component 3 of the waste conveying device in the related art sends the loose waste at the bottom of the silo 1 out of the silo 1 along the radial direction of the silo 1, the loose waste is easily accumulated on the inner wall of the silo 1, and the loose waste in the silo 1 is easily entangled with each other, thereby involving the waste in the feeding component 3, affecting the conveying efficiency of the loosening component 4. The waste conveying device of the embodiment of the present invention is provided with a loosening component 4 on the side wall of the silo 1. When the loosening component 4 conveys the waste and causes the waste to accumulate on the side wall of the silo 1, the loosening component 4 can stir the waste accumulated on the inner wall of the silo 1, and further break up the loose waste involved in the feeding component 3.

[0031] The waste conveying device of the embodiment of the present invention is provided with a loosening component 4 in the silo 1. On the one hand, it prevents the waste from accumulating on the inner wall of the silo 1 along the extension direction of the feeding component 3, so that the waste conveying device of the embodiment of the present invention discharges the material evenly. On the other hand, it prevents the waste accumulated in the silo 1 from involving the waste in the feeding device, thereby preventing the feeding component 3 from being blocked by the loose waste accumulated on the inner wall of the silo 1, thereby making the waste conveying device of the embodiment of the present invention have the advantage of higher reliability.

[0032] In some embodiments, the feeding assembly 3 includes a shell 31 and a spiral feeding mechanism 32. The shell 31 is connected to the lower end of the silo 1. The upper end of the shell 31 has an opening extending radially along the silo 1 to allow the loose waste in the silo 1 to fall into the shell 31 under the action of gravity. The spiral feeding mechanism 32 can be rotatably assembled in the shell 31 to drive the loose waste in the shell 31 to move axially along the shell 31.

[0033] Specifically, the shell 31 extends in the left-right direction, and an assembly groove is provided in the shell 31, which extends in the left-right direction. An opening is provided on the upper side of the assembly groove to connect the inner cavity of the silo 1 and the assembly groove in the shell 31, so that the waste in the silo 1 falls into the shell 31 under the action of gravity. The lower end of the right side of the shell 31 is connected to the discharge pipe 2, and a spiral feeding mechanism 32 is installed in the shell 31. The spiral feeding mechanism 32 extends in the left-right direction in the shell 31, and the spiral feeding mechanism 32 can rotate along its circumference to transport the waste falling in the shell 31 from left to right in the shell 31, and transport the waste in the shell 31 to the discharge pipe 2 through the lower end of the right side of the shell 31.

[0034] The spiral feeding mechanism 32 and the shell 31 form a screw conveyor to transport the waste in the silo 1 to the discharge pipe 2. The waste in the silo 1 is loose waste formed by industrial waste such as waste spinning. The waste in the silo 1 is easily entangled and solidified with each other. The spiral feeding mechanism 32 drives the waste to move from left to right in the shell 31, which can effectively prevent the waste transported in the shell 31 from being entangled on the rotating shaft of the spiral feeding mechanism 32 and affecting its rotation, so that the waste conveying device of the embodiment of the present invention is suitable for conveying industrial waste such as waste spinning.

[0035] In some embodiments, the loosening component 4 includes a loosening roller 41, which is rotatably disposed on the inner wall of the silo 1, and the loosening roller 41 extends in a horizontal direction. A first shifting member is provided on the surface of the loosening roller 41. As the loosening roller 41 rotates, the first shifting member can stir the loose waste accumulated on the upper side of the feeding component 3.

[0036] Specifically, the loosening roller 41 extends in the left and right directions, the loosening component 4 is arranged at the right end of the inner wall of the silo 1, and the loosening component 4 is located on the upper side of the connection between the feeding component 3 and the right end of the shell 31. The loosening roller 41 can rotate along its rotating axis to stir the waste material around it through the first shifting member, so as to achieve the purpose of loosening the waste material near the loosening component 4.

[0037] In some embodiments, the loosening roller 41 rotates in opposite directions to the spiral feeding mechanism 32. Therefore, when the waste material around the loosening roller 41 and the waste material on the outer peripheral side of the spiral feeding mechanism 32 are entangled with each other, the waste material around the loosening roller 41 and the waste material on the outer peripheral side of the spiral feeding mechanism 32 can be separated by the reverse rotation of the loosening roller 41 and the spiral feeding mechanism 32, thereby preventing the waste material around the loosening roller 41 from being entangled with the waste material on the outer peripheral side of the spiral feeding mechanism 32 and affecting the rotation of the spiral feeding mechanism 32.

[0038] In some embodiments, the first driving member includes a spiral loosening mechanism 42 , which spirally extends along the outer peripheral side of the loosening roller shaft 41 and the axial direction of the loosening roller shaft 41 .

[0039] In some embodiments, the extension direction of the discharge pipe 2 is orthogonal to the extension direction of the feeding assembly 3. A spiral discharge mechanism (not shown) is provided in the discharge pipe 2 and is rotatably assembled in the discharge pipe 2 to transport the loose waste in the discharge pipe 2.

[0040] Specifically, the discharge pipe 2 extends in the front-to-back direction, and the feed assembly 3 extends in the left-to-right direction. The orthogonal arrangement of the discharge pipe 2 and the feed assembly 3 allows the waste in the feed assembly 3 to be properly accumulated at the connection between the feed assembly 3 and the discharge pipe 2, thereby isolating the inner cavity of the feed assembly 3 from the inner cavity of the discharge pipe 2. This prevents smoke from escaping from the discharge pipe 2 through the feed assembly 3 into the silo 1.

[0041] In some embodiments, the waste conveying device also includes a material diverting component 5, which is arranged in the silo 1 and is located on the upper side of the loosening component 4. The material diverting component 5 is suitable for conveying the loose waste in the silo 1 downward to the feeding component 3.

[0042] Specifically, the material-digging assembly 5 is arranged at the middle position of the silo 1 in the vertical direction, so as to convey the waste material on the upper side of the material-digging assembly 5 to the lower side of the material-digging assembly 5. Thus, on the one hand, the material-digging assembly 5 can promote the downward movement of the loose waste material in the silo 1, and prevent the loose waste material from being entangled with each other in the silo 1 and affecting its falling to the feeding assembly 3. On the other hand, the material-digging assembly 5 can appropriately increase the internal pressure of the waste material between the material-digging assembly 5 and the feeding assembly 3, thereby pressing the waste material in the silo 1 downward into the feeding assembly 3, preventing the waste material from being entangled and solidified on the upper side of the feeding assembly 3, and preventing the spiral feeding mechanism 32 of the feeding assembly 3 from idling, thereby improving the conveying efficiency of the feeding assembly 3.

[0043] In some embodiments, the material-digging assembly 5 includes a plurality of material-digging roller shafts 51, which are rotatably arranged on the inner side of the hopper 1, and a plurality of second digging members are provided on the surface of the material-digging roller shaft 51 so that the loose waste materials on the outer peripheral side of the material-digging roller shaft 51 can be moved along its circumferential direction under the digging of the material-digging roller shaft 51.

[0044] Specifically, the plurality of feed roller shafts 51 include adjacent first and second feed rollers 501 and 502 that are arranged in parallel and spaced apart. The first and second feed rollers 501 and 502 rotate in opposite directions to transport the loose waste between the first and second feed rollers 501 and 502 to the lower side.

[0045] Furthermore, the first feed roller 501 rotates in a clockwise direction, and the second feed roller 502 rotates in a counterclockwise direction.

[0046] In some embodiments, the material-digging roller shaft 51 extends in a horizontal direction, and the material-digging roller shaft 51 is orthogonal to the extension direction of the feeding assembly 3 .

[0047] In some embodiments, the second shifting member includes multiple spiral shifting mechanisms 52 and multiple groups of shifting teeth 53, which are alternately arranged along the axial direction of the shifting roller shaft 51, and the rotation directions of any two adjacent spiral shifting mechanisms 52 are opposite.

[0048] Specifically, when the spiral material-digging mechanism 52 moves the waste material around it, the waste material around the spiral material-digging mechanism 52 can be moved along its rotation direction to the teeth 53 at the end of the spiral material-digging mechanism 52, and the waste material is moved by the multiple teeth 53 on the material-digging roller shaft 51. On the one hand, the spiral material-digging mechanism 52 prevents the waste material from being entangled on the material-digging roller shaft 51 and can reduce the rotational resistance of the spiral material-digging mechanism 52. On the other hand, the teeth 53 arranged at the end of the spiral material-digging mechanism 52 improve the conveying capacity of the waste material on the outer peripheral side of the material-digging component 5.

[0049] An embodiment of the present invention further provides a waste disposal system.

[0051] Furthermore, the flue gas duct is a low-temperature flue gas duct.

[0052] Specifically, the waste treatment system of the embodiment of the present invention separates a low-temperature flue gas flow from the waste gas flow generated by the pulverized coal furnace. The low-temperature flue gas flow flows in the low-temperature flue gas pipe and flows back to the pulverized coal furnace. At the same time, the crushed waste in the feeding assembly is carried back to the furnace chamber of the pulverized coal furnace, so that the powder replaces part of the fossil fuel for combustion in the furnace chamber of the pulverized coal furnace. The crushed waste is carried by the low-temperature flue gas, which avoids the waste from being heated, coked and agglomerated, thereby facilitating the transportation of the crushed waste by the low-temperature flue gas flow, thereby avoiding the crushed waste from being blocked during transportation, and thus making the waste treatment system of the embodiment of the present invention have the advantages of high reliability and high waste utilization efficiency.

[0053] The waste conveying device of the embodiment of the present invention is provided with a feeding component 3 and a discharge pipe 2 between its silo 1 and the low-temperature flue gas pipe. The feeding component 3 is connected to the silo 1, and the discharge pipe 2 is connected to the low-temperature flue gas pipe. The waste in the silo 1 is transported in the feeding component 3 and the discharge pipe 2 until it can produce appropriate accumulation between the feeding component 3 and the discharge pipe 2, isolating the inner cavity of the feeding component 3 and the discharge pipe 2, thereby preventing the low-temperature flue gas in the low-temperature flue gas pipe from escaping into the waste conveying device, thereby improving the safety of the waste treatment system of the embodiment of the present invention.
