Description

Cake feeder system {Cake feeder system}

The present invention relates to a cake feeder system that can control the supply of moisture-containing raw materials to a rotary kiln device in a fixed quantity.

With the development of industry, the production of products made from plastic or synthetic rubber is rapidly increasing, but the recycling rate for waste synthetic resins such as waste plastic and waste rubber is only at a negligible level compared to the total production.

The main reason why this phenomenon occurs is because a lot of expenses are spent on recycling waste synthetic resin.

Recycling of waste synthetic resin costs a lot of money for various reasons, but the main reason is that waste synthetic resin contains various substances.

In other words, waste synthetic resin can be recycled if it is of very high purity, but if it is of low purity, it costs a lot of money to recycle it.

Therefore, it is not good from an economic perspective, and even if recycled, there is a limit to recycling because the quality deteriorates after reuse.

A technology to recycle waste synthetic resin while reducing costs includes thermal decomposition of waste synthetic resin.

The thermal decomposition recycling method of waste synthetic resin is a method of melting and decomposing waste synthetic resin by applying high heat to the waste synthetic resin, and purifying various oils obtained from the decomposition product to obtain oil.

The pyrolysis system of waste plastic using a conventional rotary kiln-type pyrolysis device uses a rotary kiln-type pyrolysis device to first pyrolyze waste synthetic resin, uses a CSTR-type pyrolysis device to pyrolyze the primary decomposition product again, and uses a distillation tower to pyrolyze the waste plastic resin. After securing product oil from tea decomposition products, this product oil is purified to secure high purity oil.

In addition, in the conventional pyrolysis device, wastes of rough shape and various types were mixed in the input device.

For example, waste includes waste vinyl with a low specific gravity and a large amount of waste plastic with a high specific gravity.

However, there was a frequent occurrence of the material not being injected due to clumping of waste vinyl at the inlet.

In particular, this problem frequently occurred in the inlet area of the horizontal pipe.

In addition, waste vinyl or waste plastics agglomerate during the transfer process using screws, causing the transfer axis to stop or jam, screw damage, or overload.

And, even when the transfer of the input material was completed and it fell into the vertical pipe, it would stick to the inner wall of the pipe or become entangled with each other, preventing it from falling, resulting in a blockage.

In this case, the entire system had to be stopped, cooled sufficiently, and then dismantled by drilling or breaking the hardened vinyl or waste plastic with a tool.

And in order to operate the system again, sufficient preheating and preparation processes were required.

As a result, the efficiency of the pyrolysis device was dependent on the smooth input of the input device rather than the pyrolysis reactor.
