Abstract
The utility model discloses an infrared radiation ceramic heater which comprises an electrothermal tube and a ceramic shell; the electrothermal tube is enclosed in a first cavity enclosed by the ceramic shell, and the part of the ceramic shell located one side of the electrothermal tube forms a second cavity which is isolated from the first cavity. The second cavity is a closed cavity or is filled with thermal insulation materials. The infrared radiation ceramic heater utilizes air or the thermal insulation materials to conduct thermal insulation, so that the external temperature of the ceramic shell close to one side of the second cavity is greatly decreased, and the heat emission is reduced; the external temperature of the ceramic shell far from the side of the second cavity normally rises to emit infrared rays so as to effectively heat objects to be heated. Therefore, the infrared radiation ceramic heater can not only effectively heat the objects but also can reduce heat loss, increase the heat utilization ratio and greatly improve energy-saving and environmental-protection effect.
Description
Technical field
The utility model belongs to the technical field of firing equipment, particularly a kind of infrared radiation ceramic heater.
Background technology
Infrared radiation ceramic heater is widely used in device of plastic processing and other industry, can heat heating object (as plastics etc.).The structure of infrared radiation ceramic heater is to add electrothermal tube in ceramic shell, during work the infrared radiation ceramic heater of high temperature to around send infrared ray, thereby the object in the infrared radiation scope is heated.Traditional infrared radiation ceramic heater not enough as follows: because heating object only is positioned at a side of infrared radiation ceramic heater usually, infrared radiation ceramic heater then be to around all directions all send radiation, therefore, only there is the infrared ray heat of a side of close heating object to obtain utilizing, the infrared ray heat that another opposite side sends then is dispersed in the air in vain, become reactive loss, wasted heat not only, reduce the heat energy utilization rate, but also the workshop temperature is raise, allow the workman feel under the weather, or more increase the burden of air-conditioning.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of infrared radiation ceramic heater is provided, and it can reduce thermal losses, improves the heat energy utilization rate.
Its purpose can realize by following scheme: this infrared radiation ceramic heater comprises electrothermal tube, ceramic shell, electrothermal tube is enclosed in first cavity that ceramic shell surrounds formation, be primarily characterized in that, the ceramic shell position that is positioned at a wherein side of electrothermal tube is formed with second cavity, and this second cavity and first cavity are isolated.
Be preferably, described second cavity is a sealed hollow.
Be more preferably, filling has heat-barrier material in described second cavity.
The utlity model has following advantage and effect:
1, infrared radiation ceramic heater of the present utility model wherein is formed with second cavity in the position of a side at ceramic shell, heat-barrier material or air are arranged in second cavity, it is heat insulation to utilize air or heat-barrier material to carry out, this ceramic shell appearance temperature near second cavity, one side is reduced significantly, reduce heat and distribute; Then normally heat up away from the ceramic shell of a side of second cavity and to send infrared ray, can effectively heat heating object.Therefore the utility model can effectively heat object, can improve the heat energy utilization rate again, can play bigger raising effects of energy conservation and environmental protection in actual the use, and can reduce the workshop intensification.
