Mixing furnace for plastic additive preparation

Abstract

The invention belongs to the field of plastic additive production, and particularly relates to a mixing furnace for plastic additive preparation. The mixing furnace comprises a barrel-shaped furnace body with an opening formed in the upper end. A discharging pipe is arranged at the bottom of the furnace body and is controlled by a valve to be opened and closed. A first barrel is arranged on the periphery of the furnace body, acrinyl formic acid is contained in a water bath room between the furnace body and the first barrel, and the melting point of the acrinyl formic acid ranges from 214 DEG Cto 217 DEG C. The periphery of the first barrel is sleeved with a second barrel, a combustion chamber is formed between the second barrel and the first barrel, a set of air inlets is arranged at thebottom of the combustion chamber, and a set of exhaust openings is arranged at the top of the combustion chamber. A set of gas spray pipes is arranged at the bottom of the combustion chamber, and thegas spray pipes communicate with a natural gas source through solenoid valves and pipelines. The melting state of the acrinyl formic acid is observed, the gas spray pipes are controlled to heat the water bath room, the mixing temperature of a mixture in the furnace body can be controlled conveniently and rapidly, and then it is guaranteed that mixing is carried out smoothly.

Description

technical field [0001] The invention belongs to the field of production of plastic additives, in particular to a fusion furnace for preparing plastic additives. Background technique [0002] As we all know, with the rapid development of the petrochemical industry after the middle of the 20th century, plastic materials have become the most important materials in people's daily life, such as plastic bags, plastic cups, shells of most home appliances, shoe materials, tableware, raincoats, agricultural products, etc. Films, packaging films, containers, stationery, leisure products, household products, etc. are all plastic products, so plastic materials are inseparable from people's daily life, but the biggest disadvantage of plastic materials lies in their waste disposal. If the method of incineration is used for thousands of years, the service life of the landfill will be greatly reduced; if incineration is used, the plastic products will produce toxic gases such as dioxin, HCN...

AI Technical Summary

Problems solved by technology

[0003] In order to make up for the deficiencies of the existing technology, solve the serious air pollution caused by the waste of plastic materials when incinerated, and at the same time, the raw materials need to be mixed and melted in the production process of plastic products, and the melting temperature control system is relatively complicated and the cost is high. , a fusion furnace for the preparation of plastic additives proposed by the present invention
