Description

Technical Field

[0001] The utility model relates to the field of waste tire recycling, in particular to a device for pyrolyzing carbon black from waste tires. Background Art

[0002] After the waste tires are recycled, they are generally decomposed into fuel oil, carbon black and steel wire through refining equipment to achieve resource recycling. During the tire cracking process, the fuel oil generated by the reaction will be directly discharged from the cracking reactor in a gaseous state and condensed into liquid fuel oil through a condensing mechanism. After the tire cracking is completed, the carbon black generated by the reaction will be discharged from the cracking reactor through the slag discharge system.

[0003] The current waste tire pyrolysis carbon black equipment, as described in the patent with announcement number CN217265553U, includes a tank body, a motor base is fixedly installed at the bottom of the tank body, and a reducer is fixedly installed on the motor base, a water jacket is provided on the outside of the tank body, a spiral blade is installed in the tank body, and the screw of the spiral blade is a hollow structure, both ends of the spiral blade are connected to waste heat recovery pipelines installed through bearings, one end of the spiral blade is transmission-connected to the output shaft end of the reducer through a sprocket, and a cover plate is installed on the top of the tank body by bolts.

[0004] With regard to the above-mentioned related technologies, the inventors believe that by providing a water jacket on the outside of the spiral conveyor trough body connected to a circulating water cooling system, the discharged carbon black will not be overheated and damage the slag discharge device. However, the water flow path inside the water jacket is short, which makes it difficult to fully exchange heat between water and carbon black, resulting in a low heat recovery rate in the carbon black.

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] See also Figure 1-4A carbon black equipment for waste tire pyrolysis includes a conveying trough 1, wherein a spiral conveying blade 12 is rotatably connected inside the conveying trough 1, a conveying motor 13 is fixedly connected to one side of the outer wall of the conveying trough 1, and the output end of the conveying motor 13 is fixedly connected to one end of the spiral conveying blade 12. The conveying motor 13 is arranged to drive the spiral conveying blade 12 to rotate when starting work, so as to convey the carbon black discharged into the conveying trough 1 through the spiral conveying blade 12. A matching cover plate 3 is arranged on the top of the conveying trough 1, and the cover plate 3 is arranged to cover the top of the conveying trough 1. A U-shaped plate 2 is detachably connected to the bottom of the cover plate 3, and connecting bolts 11 are evenly threadedly connected to both sides of the cover plate 3. Each group of connecting bolts 11 is threadedly connected to the U-shaped plate 2. The use of connecting bolts 11 to fix the U-shaped plate 2 and the cover plate 3 can facilitate the subsequent disassembly of the U-shaped plate 2 and the cover plate 3.

[0023] The U-shaped plate 2 is sleeved on the outside of the conveying trough 1. The setting of the U-shaped plate 2 can form a space for water flow between the conveying trough 1 and the U-shaped plate 2, so that when the water is discharged between the conveying trough 1 and the U-shaped plate 2, it can exchange heat with the water flowing inside the conveying trough 1, thereby realizing the recovery and utilization of heat in the carbon black. A sealing strip 6 is fixedly connected to the side of the U-shaped plate 2 close to the conveying trough 1. The sealing strip 6 is in contact with both the conveying trough 1 and the cover plate 3. The sealing strip 6 can seal the gap between the U-shaped plate 2 and the conveying trough 1 and between the U-shaped plate 2 and the cover plate 3, thereby reducing the probability of water leakage in the area between the conveying trough 1 and the U-shaped plate 2.

[0024] The outer wall of the conveying trough 1 is evenly and evenly fixedly connected with first spiral guide plates 4, and a second spiral guide plate 5 fixedly connected to the outer wall of the conveying trough 1 is provided between two adjacent groups of first spiral guide plates 4. The first spiral guide plate 4 and the second spiral guide plate 5 can be provided to guide the water flowing into the conveying trough 1 and the U-shaped plate 2, so that the water can alternately flow in the area between two adjacent first spiral guide plates 4 and second spiral guide plates 5, effectively increasing the flow of water, thereby improving the heat exchange effect between the water and the carbon black transported inside the conveying trough 1, and improving the utilization rate of the heat of the carbon black. An observation port 14 is provided on one side of the outer wall of the U-shaped plate 2, and a transparent glass plate 15 fixedly connected to the conveying trough 1 is provided inside the observation port 14. The arrangement of the observation port 14 and the transparent glass plate 15 can facilitate the observation of the outer wall of the conveying trough 1, so that it is convenient for maintenance personnel to understand the amount of scale in the area between the conveying trough 1 and the U-shaped plate 2, and then it is convenient for maintenance personnel to determine whether it is necessary to clean the scale on the conveying trough 1, the U-shaped plate 2, the first spiral guide plate 4 and the second spiral guide plate 5.

[0025] A feed pipe 7 is fixedly connected to one side of the top of the cover plate 3. The feed pipe 7 can be connected to the discharge port of the cracking reactor, so that the carbon black discharged from the cracking reaction can be discharged into the inside of the conveying trough 1 through the feed pipe 7. A discharge pipe 8 is fixedly connected to one side of the bottom of the conveying trough 1. The carbon black after conveying and heat exchange can be discharged through the discharge pipe 8. A water inlet pipe 10 connected to the U-shaped plate 2 is fixedly connected to one side of the cover plate 3. The water inlet pipe 10 is used to supply cold water to the area between the conveying trough 1 and the U-shaped plate 2. A drainage pipe 9 connected to the U-shaped plate 2 is fixedly connected to one side of the bottom of the U-shaped plate 2 near the discharge pipe 8. The drainage pipe 9 can be used to discharge cold water after heat exchange.

[0026] Both sides of the conveying trough 1 are connected with a connecting mechanism 16, and the connecting mechanism 16 includes L-shaped connecting screws 161 symmetrically fixedly connected to both sides of the conveying trough 1. Each group of L-shaped connecting screws 161 is fixedly connected with a reinforcing rib 163 on one side close to the spiral conveying blade 12. Each group of reinforcing ribs 163 is fixedly connected to the conveying trough 1. The reinforcing rib 163 can further connect and fix the L-shaped connecting screws 161 to the conveying trough 1, thereby improving the connection stability between the L-shaped connecting screws 161 and the conveying trough 1. The outer sides of the two groups of L-shaped connecting screws 161 on the upper side are threadedly connected with matching internal threaded tubes 162. The internal threaded tubes 162 can screw and fix the two groups of L-shaped connecting screws 161, thereby facilitating the connection and fixation of the two devices, so that when one device cannot effectively recover the heat in the carbon black, a group of the devices can be added for heat exchange, thereby further improving the utilization rate of the heat in the carbon black.

[0027] As a further solution of the utility model:

[0028] When in use, the feed pipe 7 is connected and fixed to the discharge port of the pyrolysis reactor, so that the carbon black generated by the pyrolysis of the waste tire can be discharged into the interior of the conveying trough 1 through the feed pipe 7, and then the conveying motor 13 is started, so that the conveying motor 13 can drive the spiral conveying blade 12 to rotate when starting the work, and the spiral conveying blade 12 can drive the carbon black to be transported to one side of the discharge pipe 8 when rotating, until it is discharged through the discharge pipe 8. In the process of the spiral conveying blade 12 conveying the carbon black, the water inlet pipe 10 can be connected to cold water, so that the cold water can be discharged into the area between the U-shaped plate 2 and the conveying trough 1 through the water inlet pipe 10, so as to realize heat exchange with the carbon black inside the conveying trough 1, thereby improving the utilization rate of the heat in the carbon black, and through the guidance of each group of second spiral guide plates 5 and the first spiral guide plates 4, and along various second spiral guide plates 5 The area between the first spiral guide plate 4 and the first spiral guide plate 4 flows alternately, thereby improving the flow of cold water in the area between the conveying trough 1 and the U-shaped plate 2, thereby improving the heat exchange effect between cold water and carbon black, thereby further improving the utilization rate of heat in the carbon black, and when the carbon black discharged from the discharge pipe 8 still contains a large amount of heat, one of the devices can be taken out, and the discharge pipe 8 of one device is connected and fixed with the feed pipe 7 of the device on the other side, and the internal threaded pipe 162 of one group of equipment is screwed to the outside of the L-shaped connecting screw 161 of the other group of equipment, so as to fix the two devices, and then the drain pipe 9 of one device is connected to the water inlet pipe 10 of the other side device through a pipeline, so that the carbon black discharged through one group of discharge pipes 8 can be discharged into the conveying trough 1 of another group of equipment to continue to be transported and heat exchanged, thereby further improving the utilization rate of the heat of the carbon black.
