Abstract
The utility model aims at disclosing an electric radiation heating device, which comprises an inner container and an outer container. The inner container is a vacuum furnace container; a heater is arranged at the outer side of the outer container; and the inner container and the outer container are internally provided with a temperature sensor respectively. The temperatures of the inner container and the outer container are respectively monitored through the temperature sensors arranged in the inner container and the outer container; further, the temperature compensation adjustment control is carried out, so that the temperature of the inner container is maintained in a constant-temperature state; the temperature difference of the inner container is effectively improved; when the electric radiation heating device is in use, argon can be filled in the selected inner container according to the characteristics of a product, so that the temperature in the inner container circulates along with the argon; the momentary oxidation of the product in a tapping-off process is prevented; conditions are created for the subsequent processing of the product; and the purposes of the electric radiation heating device are achieved.
Description
Technical field
The utility model relates to a kind of Equipment for Heating Processing, particularly a kind of electric radiation heater that product is heat-treated of being used for.
Background technology
Existing Equipment for Heating Processing is generally two bladder structures, and outer courage is a zone of heating, and inner bag is the vacuum flue, and outer courage arranged outside having heaters carries out heat radiation by outer courage to inner bag; During use, product is placed in the inner bag, heat energy utilizes the radiation conduction principle to be transmitted to inner bag by heater by outer courage, and inner bag is carried out radiation heating, prevents that by the vacuum flue as inner bag product from producing oxide layer in heat treatment process.
But, in actual production process, owing to be to utilize the radiation conduction principle that heat energy is radiated inner bag in the said structure by the heater outside the outer courage, cause being heated of inner bag inhomogeneous easily, make the temperature in the inner bag can't remain under the temperature constant state, product after causing handling with require inconsistent, also lower by heater simultaneously to the heat transfer efficiency of the heat exchange pattern of inner bag radiant heat energy.
In sum, at the defective of prior art, need a kind of electric radiation heater especially, to solve above-mentioned problem.
The utility model content
The purpose of this utility model is to provide a kind of electric radiation heater, solves the defective of above-mentioned prior art, inner bag be subjected to thermal balance, dwindle the difference that inner bag is accepted heat energy, make after the processing product with require consistent.
The technical problem that the utility model solved can realize by the following technical solutions:
A kind of electric radiation heater, it comprises outer courage and inner bag, described inner bag is the vacuum flue, it is characterized in that, the arranged outside having heaters of courage outside described, described inner bag and outside be respectively arranged with temperature sensor in the courage.
In an embodiment of the present utility model, the data output end of described temperature sensor connects a controller, and the control end of described controller is connected with heater.
In an embodiment of the present utility model, in described inner bag, be connected with the argon gas tube seat that is used for the filling argon gas.
In an embodiment of the present utility model, at the arranged outside one heat tracing layer of described heater.
In an embodiment of the present utility model, described heater is made up of heating wire, the outside of described heating wire uniform winding courage outside described.
Electric radiation heater of the present utility model is monitored the temperature of inner bag and outer courage respectively by the temperature control sensor that is separately positioned on inner bag and outer courage, and the trip temperature compensation adjustment of going forward side by side is controlled, and makes the temperature maintenance temperature constant state of inner bag, improves the temperature difference of inner bag effectively; Filling argon gas in inner bag simultaneously makes temperature in the inner bag along with argon gas circulates, and prevents the moment oxidation when product is come out of the stove, and for the following process of product creates conditions, realizes the purpose of this utility model.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.
Description of drawings
Fig. 1 is the structural representation of electric radiation heater of the present utility model;
Fig. 2 is the circuit block diagram of electric radiation heater of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, electric radiation heater of the present utility model, it comprises outer courage 100 and inner bag 200, inner bag 200 is the vacuum flue, the arranged outside having heaters 300 of courage 100 is provided with temperature sensor 110 in the courage 100 outside outside, is provided with temperature sensor 210 in inner bag 200.
Arranged outside at heater 300 has the heat tracing layer; Described heater 300 is formed the outside of described heating wire uniform winding courage 100 outside described by heating wire.
In the utility model, temperature sensor 110 is used to monitor the temperature of outer courage 100, and temperature sensor 210 is used to monitor the temperature of inner bag 200; The data output end of the data output end of temperature sensor 110 and temperature sensor 210 is connected a controller 400, the control end of controller 400 is connected with heater 300, the temperature signal that controller 400 reception temperature sensors 110 and temperature sensor 210 monitor, carry out temperature-compensating adjustment control by the control program in the controller 400, make the temperature of inner bag 200 keep temperature constant state; Controller 400 can adopt PLC controller etc.(referring to Fig. 2)
In inner bag 200, also be connected with an argon gas tube seat 220 that is used for the filling argon gas in the present embodiment; Having dosed argon gas in inner bag 200, on the one hand is that temperature makes the temperature in the whole inner bag 200 reach balanced along with argon gas circulates in the inner bag 200, on the other hand, avoids oxidation when product is taken out from inner bag 200, for the following process of product creates conditions.
During use, the temperature that temperature control sensor 210 by being separately positioned on inner bag 200 and outer courage 100 and temperature sensor 110 are monitored inner bag 200 and outer courage 100 respectively, the temperature signal that temperature sensor 110 and temperature sensor 210 monitor is transferred to controller 400, control program in the controller 400 carries out temperature-compensating adjustment control, make the temperature of inner bag 200 keep temperature constant state, improve the temperature difference of inner bag 200 effectively; Simultaneously in inner bag 200 by argon gas tube seat 220 filling argon gas, make temperature in the inner bag 200 along with argon gas circulates, guarantee that the temperature in the whole inner bag 200 reach balanced; When product takes out, prevent the moment oxidation when product is come out of the stove, for the following process of product creates conditions from inner bag 200.
