Description

Technical Field

[0001] This application relates to the field of solid waste treatment, and in particular to a novel slag discharger. Background Technology

[0002] In the process of processing waste tires, the waste tires are first placed inside a pyrolysis furnace, where they are then heated. After heating, the waste tires produce fuel oil and pyrolysis gas, which are then recovered. The remaining carbon black is stored inside the pyrolysis furnace.

[0003] Then, by rotating the pyrolysis furnace, the carbon black inside the pyrolysis furnace is moved toward the opening on one side of the pyrolysis furnace, so that the carbon black inside the pyrolysis furnace can be moved out from the opening on one side of the pyrolysis furnace.

[0004] The current technology involves sealing one side of the pyrolysis furnace with a sealing plate. After heating is complete, the sealing plate is removed, and then a slag discharger is installed at the opening on one side of the pyrolysis furnace, allowing the carbon black inside the furnace to be discharged through the slag discharger. This method requires multiple installations and removals of the sealing plate and the pyrolysis furnace, which is cumbersome and impacts the production efficiency of waste tires. Utility Model Content

[0005] To improve the processing efficiency of waste tires, this application provides a novel slag discharge device.

[0006] The novel slag discharger provided in this application adopts the following technical solution:

[0007] A novel slag discharger includes a housing, one side of which can seal an opening on one side of a pyrolysis furnace. A feed pipe is fixedly connected to and communicates with the side wall of the housing. A pressure plate is provided inside the housing, which slides against the inner wall of the housing and can seal one end of the opening of the pyrolysis furnace. A drive assembly is connected to the pressure plate, which is used to drive the pressure plate to separate or connect the pyrolysis furnace and the feed pipe. A bearing outer ring is fixedly sleeved on the outside of the housing and is fixedly connected to the pyrolysis furnace.

[0008] By adopting the above technical solution, during the heating of waste tires inside the pyrolysis furnace, the pressure plate seals the opening at one end of the pyrolysis furnace. After heating is completed, the pressure plate is moved by the drive component, so that the opening at one end of the pyrolysis furnace is connected to the feed pipe, thereby allowing the material inside the pyrolysis furnace to be discharged from the feed pipe. This reduces the problem of reduced waste tire processing efficiency caused by the need to disassemble the pressure plate and repeatedly install the shell.

[0009] Optionally, the drive assembly includes a first lead screw, one end of which is rotatably connected to the pressure plate, and the other end of which is away from the pressure plate is connected to the housing.

[0010] By adopting the above technical solution, when it is necessary to move the pressure plate, the pressure plate is moved by moving the first lead screw, which facilitates the process of moving the pressure plate for the staff.

[0011] Optionally, a second lead screw is threaded to the end of the first lead screw away from the pressure plate, and the end of the second lead screw away from the first lead screw passes through the housing and is threaded with a pressure cap nut, which is fixedly connected to the side wall of the housing.

[0012] By adopting the above technical solution, when it is necessary to move the pressure plate, the second lead screw is rotated. The second lead screw is connected to the pressure plate nut by thread, thereby driving the first lead screw and the pressure plate to move. When the pressure plate is moved to the side of the feed pipe away from the cracking furnace, the second lead screw is rotated alone to separate the second lead screw from the first lead screw. This reduces the space occupied by the second lead screw around the cracking furnace and facilitates the work process of the surrounding staff.

[0013] Optionally, both the first lead screw and the second lead screw have through holes in the middle, and the pressure plate also has holes that communicate with the through holes on the first lead screw. The end of the second lead screw away from the first lead screw is connected to a ball valve for sealing the through holes inside the second lead screw.

[0014] By adopting the above technical solution, during the heating of waste tires in the pyrolysis furnace, the through holes of the first and second lead screws are blocked by ball valves. After the heating is completed, the cooling water pipe is inserted into the pyrolysis furnace, thereby accelerating the cooling time of the material inside the pyrolysis furnace.

[0015] Optionally, a sealing flange is abutted against the side of the shell near the pyrolysis furnace, and the sealing flange is connected to the pyrolysis furnace and the outer ring of the bearing by fixing bolts.

[0016] By adopting the above technical solution, during the process of heating waste tires inside the pyrolysis furnace, the sealing flange can seal the gap between the shell and the pyrolysis furnace, thereby reducing the phenomenon that heat loss inside the pyrolysis furnace affects the heating process of waste tires.

[0017] Optionally, a sealing metal ring abuts between the sealing flange and the housing.

[0018] By adopting the above technical solution, the gap between the sealing flange and the shell is sealed by a sealing metal ring, thereby reducing the heat loss inside the pyrolysis furnace during the heating of waste tires.

[0019] Optionally, a baffle is provided inside the housing near the feed pipe. The side of the baffle away from the pressure plate is rotatably connected to the adjacent inner wall of the housing. A pad is fixedly connected to the side of the baffle near the feed pipe. The pad abuts against the adjacent inner wall of the housing. A wedge block is fixedly connected to the side of the pressure plate near the baffle. The wedge block is used to drive the pad to move away from the inner wall of the housing.

[0020] By adopting the above technical solution, and by setting baffles and pads, the feeding pipe can be blocked during the heating of waste tires inside the pyrolysis furnace. This reduces the occurrence of external dust entering the feeding pipe during the heating of waste tires, which would affect the collection of materials inside the pyrolysis furnace.

[0021] Optionally, a top plate is slidably inserted into the side of the pad near the pressure plate. The top plate is connected to a compression spring for moving the top plate away from the baffle. The top plate can abut against the adjacent first lead screw under the action of the pressure plate.

[0022] By adopting the above technical solution, and by setting a top plate and a compression spring, when the wedge block drives the baffle to move to a position close to the side wall of the shell away from the pyrolysis furnace, the top plate can abut against the adjacent first lead screw under the action of the compression spring. This reduces the phenomenon that the movement of the pressure plate affects the discharge of material when the material inside the pyrolysis furnace is discharged from the feed pipe.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up the shell, pressure plate and drive assembly, the phenomenon of workers having to disassemble and assemble the slag discharger multiple times during the process of discharging materials to the outside of the cracking furnace can be reduced;

[0025] 2. By setting baffles and pads, the phenomenon of external impurities entering the shell and affecting the collection of materials inside the pyrolysis furnace during the heating of waste tires inside the furnace is reduced. Attached Figure Description

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0031] This application discloses a novel slag discharger.

[0032] Example 1

[0033] Reference Figure 1 and Figure 2 A novel slag discharger includes a shell 1, which is cylindrical. The side of the shell 1 closest to the pyrolysis furnace is connected to an opening at the end of the pyrolysis furnace. A feed pipe 11 is penetrated and fixedly connected to the lower side wall of the shell 1. The feed pipe 11 communicates with the interior of the shell 1, and the axis of the feed pipe 11 is perpendicular to the axis of the shell 1.

[0034] The housing 1 is equipped with a pressure plate 2, the side wall of which slides against the adjacent side wall of the housing 1. The pressure plate 2 is used to block the opening on one side of the pyrolysis furnace. A drive assembly 3 is connected to one side of the pressure plate 2, which is used to move the pressure plate 2 to the side of the feed pipe 11 closer to the pyrolysis furnace or to the side of the feed pipe 11 farther away from the pyrolysis furnace.

[0035] The outer casing 1 is fixedly fitted with two spaced-apart bearing outer rings 4, and the outer wall of each bearing outer ring 4 is connected to the pyrolysis furnace.

[0036] During the heating of waste tires inside the pyrolysis furnace, the drive assembly 3 moves the pressure plate 2 to seal the opening on one side of the pyrolysis furnace. After heating is complete, the drive assembly 3 moves the pressure plate 2 to the side of the feed pipe 11 away from the pyrolysis furnace. Then, as the pyrolysis furnace rotates, it moves the internal material towards the opening. After entering the shell 1, the material gradually moves to the feed pipe 11 and is discharged from it. This facilitates the process of discharging the material from inside the pyrolysis furnace.

[0037] The drive assembly 3 includes a first lead screw 31 rotatably connected to the pressure plate 2, and the first lead screw 31 is perpendicular to the pressure plate 2. A second lead screw 32 is threadedly connected to the side of the first lead screw 31 away from the pressure plate 2, and the axis of the second lead screw 32 coincides with the axis of the first lead screw 31. The outer diameter of the first lead screw 31 is the same as the outer diameter of the second lead screw 32. The end of the second lead screw 32 away from the pressure plate 2 passes through the side wall of the housing 1 away from the cracking furnace and is threadedly fitted with a pressure cap nut 33. The first lead screw 31 can also be threadedly connected to the pressure cap nut 33, and the side of the pressure cap nut 33 closest to the housing 1 is fixedly connected to the housing 1.

[0038] When it is necessary to move the pressure plate 2, the second lead screw 32 is rotated to drive the first lead screw 31 and the pressure plate 2 to move, thereby realizing the process of moving the pressure plate 2 through the drive assembly 3. After the pressure plate 2 is moved to the side of the feed pipe 11 away from the cracking furnace, the second lead screw 32 is rotated to separate the second lead screw 32 from the first lead screw 31, thereby reducing the space occupied by the slag discharger and facilitating the work of the staff around the slag discharger.

[0039] Both the first lead screw 31 and the second lead screw 32 have through holes at their midpoints. Similarly, the pressure plate 2 has a hole at its midpoint that connects to the through holes at the midpoints of the first and second lead screws 31 and 32. A ball valve 34 is connected to the side of the second lead screw 32 furthest from the first lead screw 31.

[0040] By providing a through hole between the first lead screw 31, the second lead screw 32, and the pressure plate 2, it is convenient for workers to connect water pipes to the pyrolysis furnace to cool the materials inside after heating the waste tires inside the furnace. Furthermore, the presence of a ball valve 34 allows for the sealing of the through hole between the first lead screw 31 and the second lead screw 32, which connects to the outside, during the heating process inside the pyrolysis furnace, ensuring that the waste tires are fully heated.

[0041] A sealing flange 5 is provided on the side of the shell 1 near the pyrolysis furnace, and the sealing flange 5 is arranged coaxially with the shell 1. The side of the sealing flange 5 near the pyrolysis furnace is fixedly connected to the side wall of the pyrolysis furnace at the opening on one side of the pyrolysis furnace by fixing bolts 51, and the fixing bolts 51 are also fixedly connected to the outer ring 4 of the bearing. A sealing metal ring 6 abuts between the sealing flange 5 and the adjacent side wall of the shell 1.

[0042] By setting a sealing flange 5 and a sealing metal ring 6, a stable connection between the shell 1 and the pyrolysis furnace can be achieved.

[0043] The implementation principle of Example 1 is as follows: When heating waste tires, the first lead screw 31 and the second lead screw 32 drive the pressure plate 2 to seal the opening at one end of the pyrolysis furnace. After heating is completed, rotating the first lead screw 31 and the second lead screw 32 moves the pressure plate 2, thereby connecting the opening at one end of the pyrolysis furnace with the feed pipe 11. This allows the material inside the pyrolysis furnace to be discharged from the feed pipe 11.

[0044] Example 2

[0045] Reference Figure 3 The difference between this embodiment and Embodiment 1 is that a baffle 7 is provided inside the shell 1, and the baffle 7 is positioned inside the shell 1 above the feed pipe 11. The side of the baffle 7 away from the pyrolysis furnace is rotatably connected to the adjacent inner wall of the shell 1. A pad 71 is fixedly connected to the side of the baffle 7 near the feed pipe 11. The side of the pad 71 away from the baffle 7 is set as an arc-shaped surface, and the side of the pad 71 away from the baffle 7 can fit against the shell 1 and block the port connecting the feed pipe 11 and the shell 1.

[0046] A wedge block 21 is fixedly connected to the side of the pressure plate 2 closest to the baffle 7 and the end closest to the feed pipe 11. The side of the wedge block 21 away from the pressure plate 2 is gradually tilted from top to bottom away from the pressure plate 2.

[0047] When the pressure plate 2 seals the opening on one side of the pyrolysis furnace, the baffle 7 drives the pad 71 to seal the feed pipe 11, thereby reducing the occurrence of dust and impurities entering the shell 1.

[0048] A top plate 72, shaped like a C, is provided on the side of the housing 1 near the pressure plate 2, with the C-shaped opening of the top plate 72 facing the side near the pressure plate 2. A connecting rod 73 is fixedly connected to the side of the top plate 72 away from the pressure plate 2, and the side of the connecting rod 73 away from the top plate 72 is slidably inserted into the baffle 7. A compression spring 74 is fixedly connected to one end of the connecting rod 73 that is inserted into the pad 71, and the end of the compression spring 74 away from the connecting rod 73 is fixedly connected to the opposite side wall of the pad 71.

[0049] As the pressure plate 2 moves closer to the baffle 7, the wedge block 21 drives the top plate 72 and the baffle 7 to rotate upward. When the baffle 7 rotates to a state where it is in contact with the inner wall of the housing 1, the top plate 72, driven by the compression spring 74, abuts against the adjacent first lead screw 31, thereby further restricting the position of the first lead screw 31 and further fixing the position of the pressure plate 2.

[0050] The implementation principle of Example 2 is as follows: During the process of heating waste tires in the pyrolysis furnace, the baffle 7 moves towards the feed pipe 11 under the action of gravity, and the feed pipe 11 is blocked by the pad 71.

[0051] After heating is completed, the pressure plate 2 moves towards the baffle 7 under the drive of the first lead screw 31 and the second lead screw 32, so that the wedge block 21 drives the baffle 7 to rotate, thereby connecting the opening at one end of the pyrolysis furnace with the feed pipe 11, so that the material inside the pyrolysis furnace can be discharged from the feed pipe 11.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
