Fusion furnace for preparing plastic additives

Abstract

The invention belongs to the field of production of plastic additives, in particular to a fusion furnace for the preparation of plastic additives, comprising a cylindrical furnace body with an open upper end; There is a horn around it, and the water bath between the furnace body and the first horn is filled with p-hydroxyformic acid, the melting point of which is 214‑217°C; The bottom of the combustion chamber is provided with a group of air inlets, and the top of the combustion chamber is provided with a group of exhaust ports; the bottom of the combustion chamber is provided with a group of gas nozzles, and the gas nozzles communicate with the natural gas source through solenoid valves and pipelines; By controlling the melting state of the furnace and controlling the gas nozzle to heat the water bath, the fusion temperature of the mixture in the furnace can be conveniently and quickly controlled, thereby ensuring smooth fusion.

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
