Abstract

PROBLEM TO BE SOLVED: To provide a protective cover for heat of equipment such as a plastic injection molding machine, an extruder or an electric melting furnace.SOLUTION: In an equipment heat shielding cover, a high reflectance material with regard to radiant heat such as an aluminum foil is arranged on one surface or both surfaces of a metal plate.

Description

  The present invention relates to a heat protection cover for equipment such as a plastic injection molding machine, an extruder, or an electric melting furnace.

  A plastic injection molding machine heats resin through a mechanical facility called a cylinder provided with an electric heater on the outer periphery, and is injection-molded into various molds. Since this cylinder becomes very hot, measures against the heat of the operator are taken with a cover with an iron plate around the insulation.

  A small metal melting furnace or the like melts metal by electricity, but no measures are taken against heat.

Problems to be solved by the invention

Therefore, there were the following problems.
Most of the heat that goes outward from the electric heater attached around the cylinder of the plastic injection molding machine is radiant heat.
Currently, a facility cover with glass wool or other fiber-based heat insulating material is attached between steel plates as a countermeasure against heat, but in summer, the working environment is extremely deteriorated due to temperature and heat from the facility cover.

  Furthermore, based on the principle that heat is transferred from the hot side to the cold side, there is a lot of heat that is ineffective for production to escape from the electric heater attached around the cylinder, and the energy efficiency is very poor.

In equipment such as an electric melting furnace, insulation is not possible at all due to the high temperature, and the environment is very hot. In addition, electrical components around these high-temperature facilities may malfunction due to the influence of heat.
The present invention has been made to solve these problems.

Means for solving the problem

  This is a facility heat insulating cover in which a material having high reflectivity with respect to radiant heat such as aluminum foil is provided on one side or both sides of a metal plate.

The best mode for carrying out the present invention will be described below.
The amount of radiant heat radiated from a machine using an electric heater such as a plastic injection molding machine or the furnace body of an electric melting furnace is very large. That is, when this radiant heat is cut, the surrounding environment such as mechanical equipment is greatly improved.

  It is also known that the material 2 having high reflectivity with respect to radiant heat such as aluminum foil is effective as a method for cutting this radiant heat.

  In the present invention, a material 2 having a high reflectivity with respect to radiant heat such as aluminum foil is bonded or welded to the surface of a metal plate 1, and the surface of the material 2 having a high reflectivity with respect to radiant heat such as aluminum foil is used as a heat source It is a facility thermal insulation cover that is attached to the front.

  The material 2 having a high reflectivity with respect to radiant heat such as aluminum foil is a metal, but if it is in contact with a dissimilar metal for a long period of time, there is a possibility of causing electrical decoration. Therefore, a chemical fiber sheet or the like is applied between the metal plate 1 and the material 2 having high reflectivity with respect to radiant heat such as aluminum foil. The chemical fiber sheet also serves as a heat insulating material between the metal plate 1 and the material 2 having high reflectivity with respect to radiant heat such as aluminum foil.

  As shown in FIG. 2, it is possible to enclose and use a heat source. In this case, the surface temperature of the cover slightly rises due to air conduction heat, from which the radiation heat is released by several percent, and the surrounding environment is considerably improved. Furthermore, by sealing the heat source, the radiant heat radiated from the heat source to the outside is returned to the heat generation source again, so that a significant energy saving effect can be produced.

Effect of the invention

  In the plastic injection molding machine, by laying the equipment heat shield cover FIG. 2, the radiant heat radiated from the heat source such as the cylinder is returned to the generation source, and the energy saving effect of the equipment is obtained.

  Since the radiant heat radiated from a heating element such as a cylinder can be greatly reduced, the working environment around the drying furnace can be greatly improved. In the plastic injection molding machine, the surface temperature of the cover could be lowered by 30 ° C. compared to the cover made of heat insulating material.
