Energy-saving environment-friendly plastic rolling oven

Abstract

The invention provides an energy-saving environment-friendly plastic rolling oven, and belongs to the technical field of plastic rolling. The energy-saving environment-friendly plastic rolling oven solves the problem that the conventional plastic rolling oven cannot make combustible gas or fuel of a burner completely combusted to cause energy waste and pollute the environment. The energy-saving environment-friendly plastic rolling oven comprises a cylindrical heating chamber; the inner wall of the heating chamber is provided with at least one group of air outlet channel and air inlet channel; a burner is arranged at each air outlet channel, and is fixed on the outer wall of the heating chamber; a fan is arranged at each air inlet channel; the air outlet of the fan is communicated with the air outlet channel through a ventilating duct; the air outlet channel is provided with a combustion chamber with two ports; one port of the combustion chamber is communicated with burner ports of the burners, while the other port is communicated with the inner cavity of the heating chamber through the air outlet channel; and the combustion chamber is provided with a plurality of aeration holes communicating the air outlet channel with the inner cavity of the combustion chamber. The plastic rolling oven has the advantages of energy conservation, environment friendliness, cleanness and no pollution.

Description

technical field [0001] The invention belongs to the technical field of rotational molding, and relates to an oven, in particular to an energy-saving and environment-friendly rotational molding oven. Background technique [0002] The oven is an indispensable key component of the rotational molding machine. Because the quality of rotational molding products (uniform wall thickness, no deformation) depends on the uniformity of rotational mold temperature. Therefore, rotomolding has high technical requirements for the oven that heats the mold. In summary, there are the following points: [0003] Firstly, it is required that the oven has a high degree of sealing and good thermal insulation performance; secondly, the inner cavity of the oven should be smooth, which is conducive to the flow of circulating hot air; thirdly, the oven door should not be deformed to avoid heat loss; fourthly, the oven door should be sealed with the body without Air leakage; the fifth requirement is t...

AI Technical Summary

Problems solved by technology

[0004] In view of the sixth requirement mentioned above, the existing rotomolding machines generally only burn once, and the combustible gas or fuel cannot be fully combusted, and the residual combustible gas or fuel circulating hot air moves in the heating chamber. Coupled with insufficient oxygen, it is carbonized to form black ash that adheres to the outside of the mold or the inner wall of the heating chamber, which not only wastes fuel, but also pollutes the heating chamber and mold, and causes air pollution when it is discharged into the air, which is not environmentally friendly.
