[0002] Carbon black is a black powdery substance formed by incomplete combustion or pyrolysis of hydrocarbons in the gas phase under strictly controlled process conditions. A combustion furnace is required to process carbon black.

[0003] For example, a combustion furnace for producing carbon black with the authorization announcement number "CN218723101U" has excellent high temperature resistance, heat preservation and sealing properties, which greatly meets the strict cracking conditions and greatly improves the use effect of the device. However, when burning carbon black, the carbon black will accumulate in the combustion bottle, resulting in different combustion quality inside and outside of the carbon black, thereby reducing the work quality. At the same time, when cleaning the filter, the combustion furnace for producing carbon black needs to disassemble the fixed cylinder and take out the filter for cleaning. After the filter is cleaned, the fixed cylinder needs to be installed back, which is cumbersome, thereby reducing practicality. Utility Model Content

[0027] Working principle:

[0028] When the combustion furnace for producing carbon black is needed, the worker introduces the carbon black into the furnace body 1 through the feed tube 6. After the carbon black is introduced into the furnace body 1, the acetylene gas nozzle 5 is installed on the feed tube 6 and the bolt 15 is tightened to fix it. Then, the external water source is introduced into the water-cooled jacket layer 14 inside the furnace body 1 through the first water pipe 13. After the water in the water-cooled jacket layer 14 is full, the external power supply of the pump body 9 is connected and started. The pump body 9 guides the water source from the cold jacket layer 14. The water circulates in the cold jacket layer 14 in the above manner, which can quickly cool and keep the furnace layer temperature constant. When the carbon black is burned, the reflux pipe 4 is opened through the valve, and the hydrogen generated by the acetylene cracking reaction can be re-guided back to the combustion furnace through the reflux pipe 4, so as to adjust the negative pressure in the furnace. The filter screen 12 can prevent the solid particles generated by the cracking from entering the reflux pipe 4, thereby preventing the reflux pipe 4 from being blocked.

[0029] Connect the external power supply of motor 202 and start it, motor 202 drives rod body 203 to rotate, rod body 203 drives roller 207 to move, roller 207 drives horizontal plate 205 to move upward, at this time first spring 204 is stretched, horizontal plate 205 drives vertical plate 206 to move upward and then drives furnace body 1 to move, when roller 207 is separated from horizontal plate 205, first spring 204 retracts and drives vertical plate 206 to reset and then drives furnace body 1 to reset, in the above manner, furnace body 1 is reciprocated up and down and the carbon black in furnace body 1 is made to shake, so that the carbon black can be burned evenly, and after furnace body 1 starts to shake, the carbon black in furnace body 1 can be burned.

[0030] When the filter 12 needs to be cleaned, the cross bar 302 is rotated 90 degrees and then moved to the left. At this time, the second spring 305 is stretched. After the cross bar 302 is moved out of the frame 304, the cross bar 302 is stopped from being pulled and kept stationary. Then the frame 304 is flipped over. After the frame 304 is flipped over 90 degrees and separated from the two filters 12, the cross bar 302 is released and the spring 305 rebounds to reset the cross bar 302. The worker can take the filter 12 out of the box 8 and clean it. The limit on the filter 12 is canceled in the above manner. After the two filters 12 are cleaned, they are reset according to the above manner and the filter 12 is limited again. The cleaning work of the filter 12 is completed in the above manner.
