Description

Technical Field

[0001] This utility model relates to the field of waste tire pyrolysis technology, specifically a waste tire pyrolysis carbon black cooling device. Background Technology

[0002] The pyrolysis technology of waste tires involves breaking down the rubber polymers of waste tires into pyrolysis gas, pyrolysis oil, and pyrolysis carbon black at specific temperatures under conditions of oxygen deficiency or inert gas presence. The pyrolysis gas is the energy source for the pyrolysis of waste tires, while the oil and carbon black produced are the main products of the pyrolysis. Due to the high temperature of the carbon black, air may enter the carbon black when it is discharged from the carbonization device into the storage or conveying device, which can easily lead to combustion.

[0003] According to application number 202223559975.7, a waste tire pyrolysis and carbonization cooling system is disclosed, comprising: a cooling shell with a cooling coil arranged in an internal interlayer. After the carbon black is heated and carbonized, it is discharged into the cooling shell. After discharge, a drive motor drives a transmission belt to rotate, thereby driving a conveyor shaft and a spiral auger blade to rotate, conveying the material backward. During the conveying process, cooled nitrogen gas is discharged through an air inlet pipe, and then the nitrogen gas is discharged into an exhaust port through a ventilation chamber. The cooled nitrogen gas serves two purposes: firstly, it cools the carbonized carbon black, and secondly, it provides protection against high-temperature spontaneous combustion of the carbon black. The exhaust ports are evenly distributed on the spiral auger blades, ensuring uniform distribution of the discharged material within the cooling shell, guaranteeing effective cooling. During the cooling process, cooling water is discharged into the cooling coil, providing a secondary cooling operation for the internal material, significantly reducing the possibility of smoldering after discharge.

[0004] The following problems still exist in actual use:

[0005] The aforementioned equipment cools the carbon black by introducing external nitrogen gas while discharging the material. However, the nitrogen gas intake cannot be adjusted. When the amount of material entering decreases, continuously supplying a large amount of nitrogen gas will result in nitrogen waste. Furthermore, the secondary cooling method uses cooling coils, which leads to unsatisfactory cooling effect. Utility Model Content

A flipping assembly 5 is provided inside the cooling pipe 1. The flipping assembly 5 includes a rotating shaft 501, an auger blade 502, a first gear 503, a drive motor 504, and a second gear 505.

An air inlet pipe 8 is fixedly installed at one end of the rotating shaft 501 through the rotary joint 7.

[0029] The rotating shaft 501 has a ventilation chamber inside, and the exhaust port 6 is connected to the ventilation chamber inside the rotating shaft 501. When the drive motor 504 is started, it drives the gear 2 505 to rotate. The gear 2 505 drives the gear 1 503 to rotate. The gear 1 503 drives the rotating shaft 501 to rotate, thereby rotating the auger blades 502 and conveying the material backward. During the conveying process, cooled nitrogen gas is discharged through the air inlet pipe 8 and then discharged from the exhaust port 6 to cool the carbonized carbon black.

[0030] Please see Figure 1 and Figure 5A housing 2 is fixedly connected to the surface of the cooling pipe 1. Coolant 3 is disposed in the cavity formed between the housing 2 and the cooling pipe 1. A cooling assembly 4 is disposed on the surface of the housing 2. The cooling assembly 4 includes a temperature sensor 401, a lower drain pipe 402, a water pump 403, a cooling tank 404, a semiconductor refrigeration chip 405, a guide pipe 406, and an upper drain pipe 407. A temperature sensor 401 is fixedly installed on one inner wall of the housing 2. A lower drain pipe 402 is fixedly connected to the bottom of the housing 2.

A controller 12 is fixedly installed on one surface of the housing 2.

[0031] By setting up a shell 2 and a coolant 3, the carbon black is cooled by nitrogen gas while undergoing secondary cooling, thereby increasing the cooling effect. When the coolant 3 continues to work and its temperature rises, the cooling component 4 cools the heated coolant 3 again and continues to transport it into the shell 2 for circulation.

[0032] In this invention, the working principle of the device is as follows:

[0033] In use, carbon black enters the interior of cooling pipe 1 through feed port 10. Then, drive motor 504 is started to drive gear 2 505 to rotate. Gear 2 505 drives gear 1 503 to rotate. Gear 1 503 drives shaft 501 to rotate, thereby driving auger blades 502 to rotate and convey the material backward. During the conveying process, cooled nitrogen gas is discharged through air inlet pipe 8. The nitrogen gas is discharged from exhaust port 6 after passing through the ventilation chamber in shaft 501, which cools the carbonized carbon black. When the material passes through shell 2, it exchanges heat with coolant 3 in shell 2, which cools the material a second time and increases the cooling effect.

[0034] When it is necessary to adjust the nitrogen intake, the electric push rod 906 is activated to move the movable plate 907, which in turn pushes the second column 905 and the first column 904, causing them to slide in the slide groove 908. This causes the second column 905 and the first column 904 to move in a circular motion around the rotating shaft 901, which in turn causes the top plate 911 and the connecting plate 910 to rotate. This, in turn, causes the rotating shaft 901 and the connecting sleeve 909 to rotate in different directions, ultimately causing the first disc 902 and the second disc 903 to rotate. By controlling the rotation angle of the first disc 902 and the second disc 903, the amount of nitrogen entering the cooling pipe 1 from the intake pipe 8 can be adjusted according to the needs, reducing nitrogen waste.

[0035] When the coolant 3 continues to operate and its temperature rises, the temperature sensor 401 detects the temperature of the coolant 3. When the temperature exceeds the set range, the temperature sensor 401 sends a signal. The controller 12 receives the signal and starts the water pump 403 and the thermoelectric cooler 405. After the water pump 403 starts, it draws the coolant 3 from the bottom of the housing 2 into the lower drain pipe 402, and then delivers it to the cooling tank 404. The thermoelectric cooler 405 cools the heated coolant 3 again, and then delivers it to the guide pipe 406. Finally, it flows back into the housing 2 through the upper drain pipe 407. This cycle ensures the cooling effect of the coolant 3. When the coolant 3 returns to a suitable temperature, the water pump 403 and the thermoelectric cooler 405 will be turned off to reduce energy waste.
