Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rubber and plastic pyrolysis treatment, in particular to a whole tire pyrolysis device. Background Art
[0002] Pyrolysis of scrap tires involves an irreversible thermochemical reaction in an oxygen-free or oxygen-deficient atmosphere, using high temperatures to decompose organic matter in scrap tires, releasing volatile products and forming solid char. This incomplete thermal degradation process can produce gaseous, liquid, and solid products. This method can completely pyrolyze scrap tires into useful products such as pyrolysis oil, pyrolysis carbon black, and pyrolysis non-condensable gases. The crude carbon black, after further processing, modification, and activation, can partially replace commercial carbon black.
[0003] Currently, waste tire pyrolysis is primarily divided into two methods: whole tire pyrolysis and crushed rubber block pyrolysis. Each method has its own advantages and disadvantages. Whole tire pyrolysis allows direct entry into the pyrolysis reactor without any prior processing, reducing pre-treatment investment and processing costs, resulting in better economic returns for the company. However, its disadvantage is that the steel wire produced by pyrolysis must be manually pulled out, which can easily cause dust leakage and environmental pollution. Crushing the whole tire into rubber blocks before entering the pyrolysis reactor requires significant investment in pre-treatment workshop equipment. Furthermore, converting the tire into rubber powder requires pre-processing such as wire drawing, crushing, and grinding, which means that refining rubber blocks and rubber powder into oil will increase pre-processing costs.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is described and illustrated below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0027] The present invention provides a whole tire thermal cracking device. Figure 1 This is a partial structural diagram of the whole tire thermal cracking equipment according to an embodiment of the present invention. Figure 1As shown, the whole tire thermal cracking equipment includes a kettle body 1, a kettle cover 2, a drag assembly 3, and a fixing assembly 4; the kettle cover 2 is detachably fixedly connected to one end of the kettle body 1, and a cylindrical member is provided on the side of the kettle cover 2 away from the kettle body 1, and one end of the cylindrical member is fixedly connected to the kettle cover 2; the drag assembly 3 is used to drive the kettle cover 2 away from or close to the kettle body 1; the fixing assembly 4 is fixedly connected to the drag assembly 3; Figure 2 、 3 As shown, the fixing assembly 4 includes a fixing sleeve 41 and pins 42 disposed on opposite sides of the fixing sleeve 41. The fixing sleeve 41 is mounted on the outside of the cylindrical member, and the inner dimensions of the fixing sleeve 41 match the outer dimensions of the cylindrical member. The pins 42 are positioned in a first position to clamp the cylindrical member when the dragging assembly 3 drives the kettle cover 2 away from or toward the kettle body 1. In some embodiments, tapered sleeves 43 are disposed on both sides of the fixing sleeve 41, and the pins 42 are disposed within the tapered sleeves 43.
[0028] The above-mentioned whole tire thermal cracking equipment is provided with a drag assembly 3 and a fixing assembly 4. After the cracking is completed, the drag assembly 3 and the fixing assembly 4 can be used to open the kettle cover 2 to remove the steel wire. After the material is loaded, the kettle cover 2 is closed to proceed with the next round of thermal cracking. This not only saves the equipment cost required to crush the whole tire into rubber blocks, but also achieves labor-saving operation, fast operation, and minimizes dust leakage and environmental pollution. The kettle cover 2 and one end of the kettle body 1 can be connected by various detachable methods such as threaded connection, concave-convex connection, and extrusion connection.
[0029] In order to facilitate the tightening and loosening between the kettle cover 2 and the kettle body 1, the kettle cover 2 is connected to one end of the kettle body 1 in a concave-convex manner; a rack is provided on the outer periphery of the kettle cover 2; and a tightening and unscrewing assembly 5 is included, which drives the kettle cover 2 to be unscrewed from the kettle body 1 through the rack, and drives the kettle cover 2 to be tightened with the kettle body 1 through the rack; when the tightening and unscrewing assembly 5 drives the kettle cover 2 to rotate, the pin 42 is located in the second position of the loosened cylindrical member. Figure 4 、 5 As shown, the unscrewing and tightening assembly 5 further includes a driven wheel 51 engaged with the rack, a driving wheel 52 engaged with the driven wheel 51 , and a hydraulic motor driving the driving wheel 52 to rotate, and the hydraulic motor is fixed to the towing assembly 3 .
[0030] To facilitate the fixing of the fixing assembly 4 and the unscrewing and tightening assembly 5 while simultaneously achieving the separation and reseating of the kettle cover 2 and the kettle body 1, the dragging assembly 3 is an RGV trolley with a counterweight block, a track under the RGV trolley, and a limit block on the track to limit the movement of the RGV trolley. The provision of the limit block facilitates improving the connection efficiency between the kettle body 1 and the kettle cover 2.
[0031] In order to facilitate the rotation of the kettle cover 2 so as to achieve tightening and loosening with the kettle body 1 , the dragging assembly 3 is further provided with a supporting wheel assembly that lifts the kettle cover 2 and is rotatably connected to the kettle cover 2 .
[0032] The automatic driving RGV trolley is arranged on the left side of the thermal cracking reactor. A counterweight iron is placed inside the automatic driving RGV trolley to ensure that the front tooling and the rear tooling (the front tooling and the rear tooling constitute the reactor body 1) will not overturn under load. A hydraulic station is arranged on the upper part of the frame base of the automatic driving RGV trolley. The hydraulic station is used to supply oil to the oil cylinder 44 of the fixed sleeve 41. The oil cylinder 44 is designed symmetrically on the left and right sides. The oil cylinder 44 moves the pins 42 on the left and right sides. The hydraulic station is also used to unscrew the tightening component 5. The unscrewing tightening component 5 is arranged on the lower right side of the frame base and is powered by a hydraulic motor. The hydraulic motor is provided with a driving gear, which engages with the rack provided on the reactor cover 2, driving the reactor cover 2 to run clockwise to lock it, and running counterclockwise to open the reactor cover 2. A drive motor is arranged on the lower part of the chassis of the automatic driving RGV trolley, which directly drives the front and rear wheel sets to run. A fixing sleeve 41 bracket is provided on the right side of the chassis of the automatic driving RGV trolley, a fixing sleeve 41 is provided on the fixing bracket, oil cylinders 44 and pins 42 are provided on both sides of the fixing sleeve 41, and a fixing sleeve 41 pin 42 hole is provided on the cone sleeve of the automatic locking kettle cover 2.
[0033] When the front and rear pyrolysis material fixtures are unloading the pyrolyzed steel wire, the hydraulic motor on the lower right side of the automatic RGV trolley automatically lifts it up and engages with the rack set on the kettle cover 2. It then rotates counterclockwise to open the kettle cover 2. At this time, the hydraulic motor drives the driving wheel 52 downward, dragging the fixture inside the kettle body 1 to the left. Tracks are set on both sides of the lower part of the fixture, which cooperate with the track groove inside the kettle body 1. When the automatic RGV trolley moves to the left to the limit point, the fixture track just stops at the end point on the outer edge of the kettle body 1. The movement mode of the kettle body 1 during feeding is that after the front and rear pyrolysis material fixtures are loaded with pyrolysis materials, the automatic RGV trolley drags the pyrolysis material fixture and the lower support track fixed on the kettle cover 2 to the right along the track groove inside the kettle body 1. After reaching the limit point inside the kettle body 1, the RGV automatic trolley automatically stops. The hydraulic motor drives the driving gear to rise and engage with the rack on the kettle cover 2, driving the kettle cover 2 clockwise to run and lock it, and then the hydraulic motor drives the driving wheel 52 to descend, completing a process of loading and unloading wire.
[0034] In addition, the upper rightmost part of the automatic driving RGV trolley is symmetrically equipped with support rollers for the pyrolysis reactor cover 2. A tensioning cylinder is installed on the outer side of the support roller frame to automatically adjust the position of the support rollers and the cover 2. The pyrolysis reactor cover 2 is equipped with 8 locking wedges, which cooperate with the locking cone sleeve of the pyrolysis reactor. The driving gear configured on the hydraulic motor cooperates with the rack on the cover 2 to automatically lock the cover 2.
[0035] like Figure 6As shown, the pyrolysis reactor also includes a high-temperature oil vapor collection chamber 6 connected to the high-temperature oil and gas outlet of the kettle 1, and a high-temperature oil vapor product catalytic tower 7 connected to the high-temperature oil vapor collection chamber 6. The high-temperature oil vapor product catalytic tower 7 is connected to a condenser 8. A high-temperature oil vapor outlet is located at the center of the right end plate of the pyrolysis reactor 1. The high-temperature oil vapor outlet is equipped with a dynamic and static packing box filled with sealing packing, which is compressed by a pressure cover to prevent high-temperature oil vapor leakage. High-temperature oil vapor output from the high-temperature oil vapor outlet enters the high-temperature oil vapor collection chamber 6. A heating pipe is installed vertically at the top of the high-temperature oil vapor collection chamber 6 to heat the high-temperature oil vapor collection chamber 6 during initial operation using flue gas to prevent oil vapor condensation. A high-temperature oil vapor outlet is located at the center of the right side of the high-temperature oil vapor collection chamber 6 and is connected to the air inlet of the high-temperature oil vapor product catalytic tower 7. A heavy oil outlet is located at the bottom of the high-temperature oil vapor product catalytic tower 7 and is connected to the heavy oil buffer tank. The oil vapor outlet of the high-temperature oil vapor catalytic tower 7 is vertically mounted at the top of the upper head and connected to the air inlet of the tank-in-tank cooling tower via an oil and gas transmission pipe. The oil and gas outlet of the tank-in-tank cooling tower is connected to the oil and gas inlet of the first-stage condenser 8, which is in turn connected to the oil and gas inlet of the second-stage condenser 8, which is then connected to the oil and gas inlet of the third-stage condenser 8. The cooling oil outlet of the third-stage condenser 8 is located at the lower head, and the cooling oil flows into the light oil buffer tank. A non-condensable gas-liquid separator is located on the right side of the light oil buffer tank, and the separated non-condensable gas is returned to the pyrolysis system for heating. A crude carbon black outlet is located at the bottom of the high-temperature oil vapor collection bin 6, which is connected to the feed inlet of the crude carbon black self-blocking gas and slag removal screw machine 9.
[0036] Furthermore, it also includes a slag discharge screw machine 9 connected to the slag discharge port of the kettle body 1. The discharge port of the crude carbon black self-blocking slag discharge screw machine 9 is connected to the feed port of the first-stage slag discharge screw machine 9, and the discharge port of the first-stage slag discharge screw machine 9 is connected to the feed port of the second-stage slag discharge screw machine 9. The crude carbon black discharged by the second-stage slag discharge screw machine 9 is transported to the carbon black workshop for further processing.
[0037] In some embodiments, a heating box for transferring heat to the kettle body 1 is also included. A material guiding spiral blade is also provided on the inner side of the pyrolysis kettle body 1, which is used to transport the carbon slag after the pyrolysis is completed to the outside through the slag outlet on the right. A flue gas dust collection hood is also provided on the left end face of the pyrolysis kettle body 1, which is used to collect dust brought out when the steel wire is unloaded. The high-temperature flue gas heating box provides heat for pyrolysis. The pyrolysis kettle body 1 is wrapped in the heating box. The flue gas outlets of the heating box are evenly distributed in 3 groups and vertically arranged on the upper part of the box. They are transported to the outside for desulfurization and denitrification by a main pipeline. A total of 5 sets of heating burners are provided, which are evenly distributed and located at the lower front part of the heating box. The pyrolysis kettle drive device and the active wheel 52 are arranged on the base on the right side of the kettle body 1, and cooperate with the passive gear ring of the kettle body 1 to drive the kettle body 1 to operate.
[0038] The working process of the above whole tire thermal cracking equipment is as follows:
[0039] When the cracking is completed, the drag component 3 and the fixing component 4 are used to open the kettle cover 2 to remove the steel wire. At the same time, the kettle cover 2 is closed after the material is loaded to start the next round of thermal cracking process. The equipment uses the whole tire for direct pyrolysis without crushing, which can reduce the initial processing cost and increase the efficiency of the production enterprise. There is no need to purchase additional pre-treatment production equipment, which can reduce the investment in workshop equipment. The newly designed RGV automatic operation trolley, carrying the kettle cover 2 and built-in tooling, can directly transport the whole tire into the kettle for pyrolysis. After the pyrolysis is completed, the kettle cover 2 is automatically opened to withdraw the tooling. The steel wire after the pyrolysis of the whole tire is directly collected in the tooling, and the tooling can be hoisted for unloading. The degree of automation is high, and continuous feeding can be carried out to achieve 24-hour continuous, safe and stable production.
[0040] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
