Description

Technical Field

[0001] This application relates to the technical field of tire pyrolysis equipment, and in particular to a pyrolysis furnace carbon black sealing discharge device. Background Technology

[0002] With the significant increase in vehicle ownership, the amount of waste tires is also gradually increasing. Tires are difficult to degrade, so recycling is necessary to reduce environmental pollution. A common method for treating waste tires is pyrolysis. This method primarily involves heating the tires in a pyrolysis furnace (also known as a pyrolysis furnace) to decompose them into carbon black, combustible fuel oil, and combustible gas.

[0003] A slag outlet is provided on the pyrolysis furnace to discharge carbon black. Typically, a screw conveyor is installed at the slag outlet to transport the carbon black to a designated location. For example, a waste tire pyrolysis device disclosed in patent document CN213739297U connects to the slag outlet of the pyrolysis reactor via a screw conveyor to achieve slag discharge.

[0004] In the relevant technology, during the slag discharge process, external air enters the pyrolysis furnace through a screw conveyor, causing combustion to occur inside the pyrolysis furnace, which in turn leads to a low oil yield during the tire pyrolysis process. Utility Model Content

[0005] In order to improve the oil yield of tire pyrolysis process, this application provides a pyrolysis furnace carbon black sealing discharge device.

[0006] The technical solution adopted in this application for a pyrolysis furnace carbon black sealing discharge device is as follows:

[0007] A pyrolysis furnace carbon black sealing discharge device includes a conveying device for conveying materials connected to the discharge port of the pyrolysis furnace, and a double gate mechanism. The double gate mechanism includes a slag discharge pipe and gate assemblies disposed at both ends of the slag discharge pipe to control the sealing and connection of the two ends of the slag discharge pipe. One end of the slag discharge pipe is connected to the discharge port of the conveying device.

[0008] By adopting the above technical solution, in the tire pyrolysis process, the gate assembly near the conveying equipment controls the opening of the end of the slag discharge pipe closest to the conveying equipment, while simultaneously controlling the closing of the end of the slag discharge pipe furthest from the conveying equipment. At this time, the conveying equipment transports carbon black into the slag discharge pipe, where it is temporarily stored. When the carbon black accumulates to a certain amount in the slag discharge pipe, the gate assembly seals the end of the slag discharge pipe closest to the conveying equipment, thereby disconnecting the slag discharge pipe from the conveying equipment. Simultaneously, the gate assembly at the end of the slag discharge pipe furthest from the conveying equipment controls the opening of that end, allowing the carbon black to be discharged from the slag discharge pipe. During this process, because the connection between the slag discharge pipe and the conveying equipment is disconnected, external air cannot enter the conveying equipment, thus reducing the possibility of air entering the cracking furnace.

[0009] Optionally, the gate assembly includes a partition plate that is slidably connected to the slag discharge pipe along a direction perpendicular to the length of the slag discharge pipe. Sliding the partition plate allows it to move closer to or further away from the slag discharge pipe.

[0010] By adopting the above technical solution, the sliding partition plate can be moved close to the slag discharge pipe, thereby sealing the end of the slag discharge pipe. Alternatively, the sliding partition plate can be moved away from the slag discharge pipe, thus eliminating the need to seal the end of the slag discharge pipe and allowing it to remain open.

[0011] Optionally, the gate assembly further includes an installation pipe with a sliding hole, the partition plate being slidably connected in the sliding hole, and the installation pipe being installed at the end of the slag discharge pipe and communicating with the slag discharge pipe.

[0012] By adopting the above technical solution, the sliding partition plate is inserted into the installation pipe, thereby sealing the end of the slag discharge pipe. The installation pipe also facilitates the installation of the partition plate onto the slag discharge pipe by the workers.

[0013] Optionally, the gate assembly further includes a mounting block with a sliding groove, the mounting block covering the outside of the partition plate, and the partition plate being able to move within the sliding groove.

[0014] By adopting the above technical solution, the mounting block is placed outside the partition plate to protect it and improve its service life. It also reduces the possibility of air entering the mounting pipe through the gap between the partition plate and the sliding hole.

[0015] Optionally, a cooling assembly is provided between the double-gate mechanism and the conveying equipment. The cooling assembly includes a transfer device and a cooling ring. The cooling ring is sleeved on the outside of the transfer device. The transfer device is used to convey materials. The inlet of the transfer device is connected to the outlet of the conveying equipment. The outlet of the transfer device is connected to the double-gate mechanism. The cooling ring is hollow inside and is provided with a water inlet and a water outlet.

[0016] By adopting the above technical solution, cooling water is injected into the cooling ring through the main body to cool the transfer equipment, thereby cooling the material in the transfer equipment, namely carbon black, which facilitates the subsequent collection of carbon black.

[0017] Optionally, the transfer device is a screw conveyor, and the cooling ring is sleeved on the outside of the screw conveyor and fits against the screw conveyor housing.

[0018] By adopting the above technical solution, a screw conveyor is used to transport materials. The materials move along the side wall of the screw conveyor, while the cooling ring directly cools the outer shell of the screw conveyor, thus improving the cooling effect on the materials.

[0019] Optionally, the cooling components are configured in multiple groups, and the transfer devices of two adjacent groups of cooling components are interconnected.

[0020] By adopting the above technical solution, the transfer equipment of multiple sets of cooling components are interconnected to realize long-distance material transportation, and the material is cooled multiple times through the cooling ring to improve the cooling effect.

[0024] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0025] This application discloses a pyrolysis furnace carbon black sealing discharge device.

[0026] Reference Figure 1 and Figure 2A pyrolysis furnace carbon black sealing discharge device includes a conveying device 1 and a double-gate mechanism 2. The conveying device 1 is used to convey materials (i.e., carbon black). In this embodiment, the conveying device 1 is a screw conveyor. The double-gate mechanism 2 includes a slag discharge pipe 21 and two sets of gate assemblies 22. The two sets of gate assemblies 22 are respectively installed at both ends of the slag discharge pipe 21 and are used to control the sealing and opening of both ends of the slag discharge pipe 21. One set of gate assemblies 22 is installed at the discharge port of the conveying device 1, and one end of the slag discharge pipe 21 is connected to the discharge port of the conveying device 1. The gate assembly 22 can control the connection and disconnection between the slag discharge pipe 21 and the discharge port of the conveying device 1.

[0027] Reference Figure 1 and Figure 2 In the tire pyrolysis process, the gate assembly 22 between the slag discharge pipe 21 and the conveying equipment 1 controls the connection between the slag discharge pipe 21 and the conveying equipment 1. At this time, the carbon black inside the conveying equipment 1 can be discharged from the discharge port into the slag discharge pipe 21. When the carbon black in the slag discharge pipe 21 reaches a certain amount, the end of the slag discharge pipe 21 away from the conveying equipment 1 is connected to the outside, and the carbon black in the slag discharge pipe 21 can be discharged. During the carbon black discharge process, the conveying equipment 1 is isolated from the outside air, thereby reducing the occurrence of outside air entering the cracking furnace through the conveying equipment 1, thus reducing the combustion reaction in the furnace and improving the oil extraction efficiency.

[0028] Reference Figure 1 and Figure 2 The gate assembly 22 includes a partition plate 221 and an installation pipe 222. The installation pipe 222 is a tubular structure and is coaxially fixedly connected to the end of the slag discharge pipe 21. A sliding hole 224 communicating with the interior of the installation pipe 222 is provided on its side wall. The partition plate 221 is slidably connected in the sliding hole 224 along a direction perpendicular to the length of the installation pipe 222. The sliding partition plate 221 allows it to be inserted into the installation pipe 222 to seal it, thereby achieving the sealing of the slag discharge pipe 21.

[0029] Reference Figure 1 and Figure 2 The mounting pipe 222 is equipped with flanges at both ends. The slag discharge pipe 21 is fixed to the mounting pipe 222 or to the discharge port of the conveying equipment 1 by flanges and screws.

[0030] Reference Figure 1 and Figure 2The gate assembly 22 also includes a mounting block 223. One side of the mounting block 223 is welded to the side wall of the mounting tube 222. A sliding groove 225 is formed on the mounting block 223 at the position corresponding to the sliding hole 224. The sliding groove 225 communicates with the sliding hole 224 to form a sliding cavity, in which the partition plate 221 can move. The mounting block 223 improves the stability of the sliding plate during sliding and reduces the possibility of air entering the mounting tube 222 through the gap between the partition plate 221 and the sliding hole 224.

[0031] Reference Figure 1 and Figure 2 The gate assembly 22 also includes a drive component 226, which is used to drive the partition plate 221 to move. In this embodiment, the drive component 226 is a hydraulic cylinder. The cylinder body of the hydraulic cylinder is fixed to the mounting block 223 by screws. The piston rod of the hydraulic cylinder is connected to the partition plate 221. The extension and retraction of the piston rod of the hydraulic cylinder can drive the partition plate 221 to move.

[0032] Reference Figure 1 and Figure 2 A cooling assembly 4 is provided between the double-gate mechanism 2 and the conveying device 1. The cooling assembly 4 includes a transfer device 41 and a cooling ring 42. The transfer device 41 is used to convey carbon black; in this embodiment, the transfer device 41 is also a screw conveyor. The cooling ring 42 has an overall annular structure and is fitted around the transfer device 41, with its inner wall fitting against the outer shell of the screw conveyor. The inlet of the transfer device 41 is connected to the outlet of the conveying device 1. The cooling ring 42 is filled with cooling water and has an inlet and an outlet. A pump promotes the circulation of the cooling water, thereby cooling the screw conveyor and consequently the carbon black inside, facilitating centralized collection and processing of the carbon black.

[0033] Reference Figure 1 and Figure 2 The cooling components 4 can be configured as multiple sets, with the inlet and outlet of adjacent sets of cooling components 4 interconnected. The double-gate mechanism 2 is installed at the outlet of the transfer device 41 in the tail cooling components 4. Multiple sets of cooling components 4 cool the carbon black multiple times, thereby improving the cooling effect of the carbon black. In this embodiment, the cooling components 4 are configured as two sets.

[0034] The implementation principle of the carbon black sealing discharge device for a pyrolysis furnace according to the embodiments of this application is as follows: the two gate components 22 intermittently control the opening and closing of the two ends of the slag discharge pipe 21, thereby ensuring that the inside of the conveying equipment 1 is always isolated from the external environment, reducing the occurrence of air from the external environment entering the pyrolysis furnace, thereby improving the oil yield of the tire refining process.

[0035] 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.
