Description

Technical Field

[0001] This application relates to the field of solid waste comprehensive utilization equipment, and particularly to a waste tire cracking furnace. Background Art

[0002] With the gradual improvement of people's living standards, private cars have gradually become the main choice for people's daily travel. The increase in private cars has led to a sharp increase in the application of private car parts, among which the easily worn tires are more prominent.

[0003] In order to protect the environment, at present, the treatment of waste tires has abandoned the previous direct combustion treatment method and has been converted to cracking waste tires through a cracking furnace, so as to collect reusable materials such as coal tar in waste tires for reuse.

[0004] At present, after the cracking furnace cracks waste tires, it often uses ventilation to cool the inside of the cracking furnace. However, this cooling often takes 8-9 hours. Only after cooling can the remaining waste materials inside the cracking furnace be taken out, and then the waste tire treatment process is completed. However, the 8-9-hour cooling time results in low efficiency of the cracking furnace in treating waste tires. Summary of the Invention

[0005] In order to improve the treatment efficiency of the cracking furnace for waste tires, this application provides a waste tire cracking furnace.

[0006] The waste tire cracking furnace provided by this application adopts the following technical scheme: A waste tire cracking furnace includes a cracking furnace body. Inside the cracking furnace body, there is a feeding member for turning over the waste tires inside the cracking furnace body. The feeding member is connected to a driving assembly that drives the feeding member to rotate. One end of the cracking furnace body is provided with an opening, and a slag discharger is connected to the opening of the cracking furnace body. The slag discharger is used to block the opening on one side of the cracking furnace body, and a water inlet pipe is penetrated and slidably inserted into the slag discharger.

[0007] By adopting the above technical scheme, the tire is placed inside the cracking furnace body for heating. During the heating process, the driving assembly drives the feeding member to turn over the materials inside the cracking furnace body. After heating is completed, the water inlet pipe is guided into the cracking furnace body and water is sprayed into the cracking furnace body, so as to accelerate the cooling process of the materials inside the cracking furnace body, and thus reduce the phenomenon that the processing efficiency of waste tires is affected due to the too long cooling time of the materials inside the cracking furnace body.

[0008] Optionally, the slag discharger includes a housing connected to the inside of the cracking furnace body. One side of the housing is connected to a feeding pipe, and a pressing plate for separating the opening on one side of the cracking furnace body and the feeding pipe is provided inside the housing.

[0009] By adopting the above technical solution, after the temperature reduction is completed, the pressing plate is moved to connect the feeding pipe with the inside of the cracking furnace body, so that the remaining materials inside the cracking furnace body can be discharged from the feeding pipe.

[0010] Optionally, the pressing plate is rotatably connected to a first lead screw. A second lead screw is detachably connected to the side of the first lead screw away from the pressing plate. Both the second lead screw and the first lead screw penetrate the housing and are threadedly connected to the housing.

[0011] By adopting the above technical solution, when it is necessary to move the pressing plate, rotating the first lead screw and the second lead screw can drive the pressing plate to move. Moreover, the first lead screw and the second lead screw are detachably connected, reducing the influence on the surrounding staff due to the long length of the lead screw during the feeding process of the feeding pipe.

[0012] Optionally, the material stirring member is a spiral blade fixedly connected to the inside of the cracking furnace body. The driving assembly includes a rotating gear disk fixedly connected to one end of the cracking furnace body away from the slag discharger. A driving gear is engaged with one side of the rotating gear disk, and a driving motor is fixedly connected to one side of the driving gear.

[0013] By adopting the above technical solution, when it is necessary to turn the materials inside the cracking furnace body through the material stirring member, the driving motor drives the driving gear to rotate. During the rotation of the driving gear, it drives the rotating gear disk to rotate. During the rotation of the rotating gear disk, it drives the cracking furnace body to rotate. During the rotation of the cracking furnace body, it drives the spiral blade to rotate, so that the spiral blade can drive the materials inside the cracking furnace body to turn over.

[0014] Optionally, the material stirring member includes an auger rod located inside the cracking furnace body. Auger blades are fixedly connected to the outer wall of the auger rod. One end of the auger rod away from the slag discharger penetrates the side wall of the cracking furnace body and is rotatably connected to the side wall of the cracking furnace body. The driving assembly includes a driving motor fixedly connected to the end of the auger rod.

[0015] By adopting the above technical solution, when it is necessary to turn over the materials inside the cracking furnace, the driving motor is started to drive the auger rod to rotate. During the rotation of the auger rod, it drives the auger blades to rotate. During the rotation of the auger blades, it drives the materials inside the cracking furnace body to move, thereby realizing the operation of turning over the materials inside the cracking furnace body through the material stirring member.

[0016] Optionally, one end of the auger rod close to the slag discharger is connected with a material turning component for turning the materials inside the cracking furnace.

[0017] By adopting the above technical solution, during the cooling process, the material turning component turns the materials inside the cracking furnace body, reducing the phenomenon that water contacts the materials insufficiently and unevenly, thus affecting the cooling process of the materials inside the cracking furnace body. Optionally, the material turning component includes a plurality of turning pipes connected to the auger rod. Each end of each turning pipe far from the auger rod is connected with a connecting block. One end of the water inlet pipe is inserted into the auger rod and is communicated with the turning pipes and the connecting block. A plurality of through holes for discharging the water inside the connecting block to the outside of the connecting block are formed in the side wall of the connecting block.

[0018] By adopting the above technical solution, during the process of the driving motor driving the auger rod to rotate, the auger rod drives the turning pipes to rotate. During the rotation of the turning pipes, the connecting blocks are driven to rotate. During the rotation of the turning pipes and the connecting blocks, the surrounding materials are turned. And since the turning pipes are communicated with the auger rod, the water inlet pipe can guide water into the connecting block and flow out from the through holes in the connecting block, thus realizing the process of making water contact the materials inside the cracking furnace body sufficiently.

[0019] Optionally, the end of the water inlet pipe is blocked and through holes are formed in the side wall. A blocking plate is slidably sleeved outside the water inlet pipe. The side wall of the blocking plate can abut against the side wall of the adjacent turning pipe. A tension spring is connected between the side of the blocking plate close to the water inlet pipe and the opposite cracking furnace body.

[0020] By adopting the above technical solution, during the process of heating waste tires, the blocking plate blocks the connection end between the turning pipe and the outside, thus reducing the phenomenon of heat loss inside the cracking furnace body.

[0021] Optionally, the blocking plate is slidably sleeved outside the water inlet pipe along the length direction of the water inlet pipe. And one end of the blocking plate far from the water inlet pipe is provided with a driving bevel gear rotatably connected to the auger rod. A socket is fixedly connected to the side of the blocking plate close to the driving bevel gear. The socket can be inserted into the driving bevel gear and limit the rotation of the driving bevel gear. A driven bevel gear is meshed with one side of the driving bevel gear close to each turning pipe. Each driven bevel gear is fixedly sleeved outside the adjacent turning pipe.

[0022] By adopting the above technical solution, after water enters the inside of the auger rod, the sealing plate moves to one side of the driving bevel gear under the drive of the water and inserts the socket into the inside of the driving bevel gear to fix the driving bevel gear. Then, during the rotation of the auger rod, the material turning pipe is driven to rotate. During the rotation of the material turning pipe, the material turning pipe rotates self by the meshing of the driving bevel gear and the driven bevel gear, so that the connecting block can spray the water inside the connecting block to the external material through rotation, thereby enabling the water to come into full contact with the material, and further realizing the full cooling process of the material inside the cracking furnace body.

[0023] Optionally, a material turning branch pipe is communicated with each through hole of the connecting block. A plurality of holes are formed in the side wall of each material turning branch pipe. A turbine is arranged at the connection of each material turning branch pipe and the connecting block. One end of each turbine close to the inside of the material turning branch pipe is fixedly connected with a driving shaft. Each driving shaft is fixedly connected with a plurality of driving sleeves. Each driving sleeve is rotationally connected with the material turning branch pipe. Each driving sleeve is penetrated and fixedly connected with a material turning connecting pipe. A plurality of holes are formed in the side wall of each material turning connecting pipe.

[0024] By adopting the above technical solution, during the self-rotation of the material turning pipe, the material turning branch pipe and the material turning connecting pipe are driven to rotate. When water flows into the inside of the material turning branch pipe, the turbine is driven to rotate. During the rotation of the turbine, the driving shaft is driven to rotate. During the rotation of the driving shaft, the driving sleeve and the material turning connecting pipe are driven to rotate, so that the material turning connecting pipe and the material turning branch pipe can turn over the surrounding materials. And during the turning process, the holes on the material turning connecting pipe and the material turning branch pipe can evenly spray water to the external materials, realizing the process of fully and evenly cooling the materials.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. After heating is completed, the water inlet pipe is inserted into the cracking furnace body and the cooling water is guided into the cracking furnace body, thereby realizing the process of water cooling the inside of the cracking furnace body, and accelerating the process of cooling the materials inside the cracking furnace body; 2.

[0031] The following further describes the present application in detail with reference to the attached Figure 1 - attached Figure 4 drawings.

[0032] Embodiment 1 of the present application discloses a waste tire cracking furnace.

[0033] Embodiment 1 Referring to Figure 1 and Figure 2 , a waste tire cracking furnace includes a cracking furnace body 1. A feeding member 2 is provided inside the cracking furnace body 1, and the feeding member 2 is used to drive the materials inside the cracking furnace body 1 to move. The feeding member 2 is connected to a driving assembly 3, and the driving assembly 3 is used to drive the feeding member 2 to rotate.

[0034] An opening is formed at one end of the cracking furnace body 1, and a slag discharger 4 is connected to the opening. The slag discharger 4 includes an outer shell 41. One side of the outer shell 41 close to the cracking furnace body 1 is fixedly connected to the cracking furnace body 1.

A feeding pipe 42 is fixedly connected to the side wall of the outer shell 41, and the feeding pipe 42 is simultaneously connected to the cavity inside the outer shell 41 and the outside.

[0035] Inside the housing 41, there is a pressing plate 43. The side wall of the pressing plate 43 is in sliding abutment with the adjacent inner wall of the housing 41 along the direction close to or away from the cracking furnace body 1. The pressing plate 43 is used to separate the feeding pipe 42 and the opening on one side of the cracking furnace body 1. On the side of the pressing plate 43 away from the cracking furnace body 1, there is a first lead screw 44. On the side of the first lead screw 44 away from the pressing plate 43, there is a second lead screw 45 detachably connected. In this embodiment, the connection mode of the first lead screw 44 and the second lead screw 45 is a threaded connection. The pressing plate 43 can be moved to the side of the feeding pipe 42 away from the cracking furnace body 1 under the drive of the first lead screw 44 and the second lead screw 45.

[0036] Both the first lead screw 44 and the second lead screw 45 penetrate through the side wall of the housing 41 away from the cracking furnace body 1 and are threadedly connected to the side wall of the housing 41. Through holes are provided in the middle of both the first lead screw 44 and the second lead screw 45, and through holes communicating with the through holes provided in the middle of the first lead screw 44 are also provided on the pressing plate 43. On the side of the second lead screw 45 away from the first lead screw 44, there is a ball valve 46 for blocking the through hole.

[0037] A water inlet pipe 5 is detachably and slidably inserted into the through holes of the first lead screw 44 and the second lead screw 45.

[0038] During actual use, by heating the cracking furnace body 1 and starting the driving assembly 3 to drive the material stirring member 2 to turn the materials inside the cracking furnace body 1, the waste tires inside the cracking furnace body 1 can be heated sufficiently and evenly. After heating is completed, the ball valve 46 is opened, and the water inlet pipe 5 is inserted into the cracking furnace body 1 to perform a cooling operation on the inside of the cracking furnace body 1.

[0039] After cooling is completed, the first lead screw 44 and the second lead screw 45 are rotated to move the pressing plate 43 to the side of the feeding pipe 42 away from the cracking furnace body 1, and then the materials inside the cracking furnace body 1 can be discharged from the feeding pipe 42.

[0040] By inserting the water inlet pipe 5 into the cracking furnace body 1 and guiding the cooling water through the water inlet pipe 5 to perform a cooling operation on the inside of the cracking furnace body 1, the time for cooling the inside of the cracking furnace body 1 can be accelerated, and thus the working efficiency of the cracking furnace for treating waste tires is increased.

[0041] The material stirring member 2 is arranged as a spiral blade 21 fixedly connected to the inner wall of the cracking furnace, and the spiral blade 21 is spirally wound into the cracking furnace body 1. The driving assembly 3 includes a rotating gear disk 31 fixedly connected to one end of the cracking furnace body 1 away from the housing 41. A driving gear 32 is meshed on one side of the rotating gear disk 31, and a driving motor 33 for driving the driving gear 32 to rotate is fixedly connected to one side of the driving gear 32.

[0042] On the lower sides of both ends of the cracking furnace body 1, there are two relatively arranged support rollers 11 for supporting the cracking furnace body 1.

[0043] During the heating process of the cracking furnace body 1, the driving motor 33 is turned on. The driving motor 33 drives the rotating gear disk 31 to rotate through the driving gear 32. During the rotation of the rotating gear disk 31, the cracking furnace body 1 is driven to rotate. During the rotation of the cracking furnace body 1, the connected spiral blades 21 and the waste tires inside are driven to rotate, thereby realizing the full stirring process of the materials inside the cracking furnace body 1.

[0044] The implementation principle of Embodiment 1 is: Place the waste tires to be processed inside the cracking furnace body 1, and then start the driving motor 33. The driving motor 33 drives the driving gear 32 to rotate. During the rotation of the driving gear 32, the cracking furnace body 1 and the spiral blades 21 are driven to rotate, realizing the full heating process of the materials inside the cracking furnace body 1.

[0045] After the heating is completed, insert the water inlet pipe 5 into the cracking furnace body 1 to guide cooling water through the water inlet pipe 5 to cool down the inside of the cracking furnace body 1. After cooling, rotate the first lead screw 44 and the second lead screw 45 to drive the pressing plate 43 to move. Then start the driving motor 33 to drive the cracking furnace body 1 to rotate, so that the remaining materials inside the cracking furnace body 1 can be discharged from the blanking pipe 42, realizing the full cleaning process of the waste tires.

[0046] Embodiment 2 Refer to Figure 3 and Figure 4 In this application, the difference between the embodiment and Embodiment 1 is that the material distributing member 2 is set as the auger rod 22, and the axis of the auger rod 22 coincides with the axis of the cracking furnace body 1. On the outer wall of the auger rod 22, there is a fixed connection with auger blades 23 spirally arranged around the auger rod 22, and the auger blades are fixedly connected to the auger rod 22.

[0047] One end of the auger rod 22 far from the slag discharger 4 penetrates the side wall of the cracking furnace body 1 and is rotatably connected to the side wall of the cracking furnace body 1. The driving assembly 3 includes a driving motor 34 fixedly connected to the end of the auger rod 22 penetrating the cracking furnace body 1.

[0048] During the actual use process, heat the cracking furnace body 1. During the heating process, turn on the driving motor 34. During the rotation of the output shaft of the driving motor 34, the connected auger rod 22 is driven to rotate. During the rotation of the auger rod 22, the auger blades 23 are driven to rotate. During the rotation of the auger blades 23, the waste tires inside the cracking furnace body 1 are driven to rotate, thereby realizing the full heating process of the waste tires inside the cracking furnace body 1.

[0049] The auger rod 22 is located inside the cracking furnace body 1, and a material turning component 6 is connected to one end of the auger rod 22 away from the driving motor 33.

[0050] By arranging the material turning component 6 to turn the materials inside the cracking furnace body 1, during the cooling process, the materials inside the cracking furnace body 1 can fully contact the cooling water guided into the cracking furnace body 1 by the water inlet pipe 5, thereby realizing the process of fully and evenly stirring the materials inside the cracking furnace body 1.

[0051] The material turning component 6 includes a plurality of turning pipes 61 rotatably inserted into one end of the auger rod 22 away from the driving motor 33. In this embodiment, the number of turning pipes 61 is set to two, and the two turning pipes 61 are oppositely arranged and perpendicular to the auger rod 22. The inside of one end of the auger rod 22 away from the driving motor 33 is hollow and can be inserted by the water inlet pipe 5. One end of each turning pipe 61 connected to the auger rod 22 is communicated with the inside of the auger rod 22.

[0052] One end of each turning pipe 61 away from the auger rod 22 is fixedly connected with a connecting block 62, and a cavity communicated with the connected turning pipe 61 is opened inside each connecting block 62. And a plurality of through holes penetrating through the connecting block 62 are opened on the side wall of each connecting block 62.

[0053] The end of the water inlet pipe 5 inserted into the inside of the auger rod 22 is sealed. A plurality of through holes are opened on the side wall of the part of the water inlet pipe 5 inserted into the auger rod 22. A sealing plate 63 is slidably sleeved on the outside of the water inlet pipe 5 along the length direction of the water inlet pipe 5. The sealing plate 63 is located at the position between the through holes opened on the water inlet pipe 5 and the turning pipe 61, and the inner wall of the sealing plate 63 is in sliding contact with the water inlet pipe 5, and the outer wall of the sealing plate 63 abuts against the end of the adjacent turning branch pipe 65 and seals the end of the turning branch pipe 65. A tension spring 631 is connected between the sealing plate 63 and the adjacent cracking furnace body 1. One end of the sealing plate 63 connected with the tension spring 631 is fixedly connected with a retaining pipe 633 sleeved on the outside of the water inlet pipe 5. The middle hole of the retaining pipe 633 gradually expands from the side close to the sealing plate 63 to the side away from the sealing plate 63, and the retaining pipe 633 can be sleeved on the outside of the through holes opened on the water inlet pipe 5.

[0054] A driving bevel gear 64 is arranged on the side of the sealing plate 63 away from the tension spring 631, and the driving bevel gear 64 is rotatably connected with the inner wall of the auger rod 22. A socket 632 is fixedly connected to the side of the sealing plate 63 close to the driving bevel gear 64, and the socket 632 is used for being inserted into the inside of the driving bevel gear 64 to limit the rotation of the driving bevel gear 64. One end of each turning pipe 61 inserted into the inside of the auger rod 22 is fixedly sleeved with a driven bevel gear 611, and each driven bevel gear 611 can be meshed with the driving bevel gear 64.

[0055] During the actual use, when guiding water into the cracking furnace body 1 through the water inlet pipe 5, the water discharges from the holes on the side wall of the water inlet pipe 5, and the water flow drives the blocking pipe 633 to move towards the side close to the blocking plate 63, so that the blocking plate 63 can drive the socket 632 to be inserted into the driving bevel gear 64 and restrict the rotation of the driving bevel gear 64. And it enables the blocking plate 63 to open the hole connecting the turning material branch pipe 65 and the auger rod 22 through movement. Then the water inside the auger rod 22 drives the blocking plate 63 to move towards the side close to the driving bevel gear 64 and drives the socket 632 to be inserted into the driving bevel gear 64, thereby restricting the rotation of the driving bevel gear 64.

[0056] Then start the driving motor 34. During the rotation of the driving motor 34, it drives the auger rod 22 to rotate. During the rotation of the auger rod 22, it drives the turning pipe 61 to rotate. During the rotation of the turning pipe 61, the turning operation is performed on the surrounding materials. During the rotation of the turning pipe 61, the driven bevel gear 611 meshes with the driving bevel gear 64 to drive the connecting block 62 to rotate. During the rotation of the connecting block 62, the water is evenly sprayed onto the surrounding materials through the holes opened on the side wall, thereby realizing the process of fully spraying water on the surrounding materials, and further realizing the operation of fully cooling the materials inside the cracking furnace body 1.

[0057] A turning material branch pipe 65 is fixedly connected to each through hole of the connecting block 62, and the inside of each turning material branch pipe 65 communicates with the internal cavity of the connected connecting block 62. A plurality of holes are opened on the side wall of each turning material branch pipe 65, and each turning material branch pipe 65 is vertically arranged with the connected turning pipe 61.

[0058] A turbine 66 is provided at a position close to the connected connecting block 62 inside each turning material branch pipe 65.

Each driving sleeve 67 is penetrated and fixedly connected with a plurality of turning connecting pipes 68. Each turning connecting pipe 68 communicates with the connected turning material branch pipe 65, and a plurality of holes are opened on the side wall of each turning connecting pipe 68.

[0059] During the actual use process, as water flows into the inside of the connecting block 62, the water inside the connecting block 62 gradually flows towards the tipping pipe branch 65. During the process of flowing into the inside of the tipping pipe branch 65, the water drives the turbine 66 to rotate. During the rotation of the turbine 66, the drive shaft 661 is driven to rotate. During the rotation of the drive shaft 661, the drive sleeve 67 and the tipping connecting pipe 68 are driven to rotate. During the rotation of the tipping connecting pipe 68, the surrounding materials are turned over and the water is discharged from the holes formed in the tipping pipe branch 65 and the tipping connecting pipe 68. Thus, a further tipping effect on the surrounding materials can be achieved, enabling the materials to come into contact with water more fully and thus achieving a cooling effect.

[0060] The implementation principle of Embodiment 2 is as follows: When it is necessary to cool down the inside of the cracking furnace body 1, first insert the water inlet pipe 5 into the inside of the auger rod 22, and start the driving motor 34. During the starting process of the driving motor 34, the auger rod 22 and the auger blades 23 are driven to rotate. During the rotation of the auger blades 23, the surrounding materials are turned over.

[0061] Meanwhile, the tipping pipe 61 drives the tipping pipe branch 65 and the tipping connecting pipe 68 to rotate. After the water enters the inside of the connecting block 62, it is discharged from the tipping pipe branch 65 and the tipping connecting pipe 68, thus realizing the process of the water coming into full contact with the surrounding materials, and further realizing the full cooling operation of the materials inside the cracking furnace body 1.

[0062] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
