A kind of rubber product microwave cracking chamber of band feedback mouth cleaning function
Technical field
A kind of the utility model microwave equipment, and in particular to rubber product microwave cracking chamber of band feedback mouth cleaning function.
Background technique
With flourishing for social economy, rubber product is widely used, but is also produced simultaneously a large amount of
Waste rubber product.Accumulative waste rubber product causes biggish harm to environment year by year.How by it in free of contamination feelings
Under condition realize minimizing, recycling, it is innoxious for improve environment, alleviating energy crisis have important strategic importance.Tradition
Processing waste rubber goods method has:It manufactures reclaimed rubber, pyrolysis, burning and generates rubber powder.Pyrolysis is useless as a kind of quickly processing
It abandons rubber and the high economic technology mode of carbon black, cracked oil and cracked gas can be generated and obtain the vast approval of society.It returns
Rotary kiln is the mainstream equipment of current pyrolysis waste old technology, but traditional cracking rubber equipment is using dividing wall type heating side
Formula, heat exchange efficiency is low, and due to the poor thermal conductivity of rubber, cracks cavity wall in the case of a high temperature and coking easily occurs, this can make
At the problems such as equipment uptime of rotary kiln thermal cracking waste old is short and energy consumption is high, traditional rubber cracking apparatus has
To further optimize.
Microwave is a kind of frequency electromagnetic waves, has extremely strong penetration capacity.Microwave can make the inside of loaded medium and outer
Portion heats up simultaneously, can avoid the problem of the heat conduction time length in conventional heating, whole heating time is greatly shortened.It is micro- simultaneously
The output power of wave is also controllable, and the temperature of rubber can change immediately, and residual activity effect is not present.Using microwave cracking rubber
Product can greatly shorten the time of cracking rubber and improve the quality of carbon black after cracking.However rubber is split microwave cracking is intracavitary
Xie Shi can generate a large amount of cracked gas, carbon black and cracked oil.A large amount of carbon black pellet and cracking oil gas are easy to attach in microwave
It presents at mouth, will lead to and generate electric discharge phenomena at microwave feedback mouth, so that the local temperature at feedback mouth can steeply rise, or even burn out micro-
Wave presents mouth sealing plate, so that the normal operation to microwave cracking equipment causes very big security risk.
