Control module who is used for monitoring and control heater operating temperature, the pressure protection module is installed above the box, the 2nd temp. Control module includes power supply and the temperature sensor who connects gradually, controller and relay, is connected with audible and visual alarm and display screen, relay and heater connection at the output of controller. This oven has increased a set of the 2nd temp. Control module who mainly comprises temperature sensor, controller, relay, audible and visual alarm and display screen and the pressure protection device that is used for monitoring the inside and outside atmospheric pressure difference of oven on the basis of original oven circuit, feasible the utility model discloses both can prevent that the bake -out temperature was too high or low excessively, and can guarantee also that the pressure in the oven was in safe state, and have the duplicate protection function, simple structure, practicality are strong.
Description
Technical field
This utility model relates to a kind of roasting plant, particularly to a kind of baking oven with double protection functions.
Background technology
Baking oven can be divided into baking box able to programme, accurate baking oven nitrogen charging baking oven, vacuum drying oven, explosion-proof baking oven, electric drying oven with forced convection, heated-air circulation oven etc. according to performance, is that a kind of all trades and professions that are widely used in need to dry the equipment of heating.Baking oven is generally mainly made up of shell, heater, controller and miscellaneous part.All it is widely used in each field such as electronics manufacturing, instrument and meter industry, plastics and rubber industry, wood industry etc..As illustrated by figure 1 of the attached drawings, in its primary circuit of baking oven that the current electron trade course of processing adopts, only a temperature controller is controlled heating, and the sensitivity of this kind of baking oven is poor, and protective effect is simple.When overtemperature, low temperature or other emergency situations occur in baking oven, postponing or even not doing any instruction occur when receiving signal in temperature controller, cause that circuit does not likely turn off, it is impossible to send alarm signal reminding employees in time, the so serious quality affecting product；Simultaneously along with the change of heating-up temperature and flowing gas density in baking oven, the pressure in baking oven also changes so that the pressure difference inside and outside baking oven is gradually increased, and the little product quality then affected in baking oven, severe patient can damage baking oven.
Utility model content
For above-mentioned deficiency; technical problem to be solved in the utility model is to provide a kind of simple in construction, the practical baking oven with double protection functions; it had both been possible to prevent baking temperature too high or too low, it is also ensured that the pressure in baking oven is in a safe condition.
For solving above-mentioned technical problem, this utility model is achieved through the following technical solutions:
A kind of baking oven with double protection functions; including casing and the heater being installed on box bottom; described heater is connected to the first temperature control module; also including pressure protection module and for monitoring and control the second temperature control module of heater operating temperature, pressure protection module is installed on above casing；Described second temperature control module includes power supply and the temperature sensor being sequentially connected with, controller and relay, and the outfan at controller is connected to an acoustic-optic alarm and a display screen, and described relay is connected with heater.
In such scheme; described pressure protection module includes baroceptor, control chip and pressure release valve cylinder; described pressure release valve cylinder is arranged on casing and is provided with for controlling the spool that pressure release valve cylinder opens and closes in pressure release valve cylinder; described baroceptor is connected with control chip, and described control chip is connected with spool.
In such scheme, when the temperature in baking oven is too high, for lowering the temperature rapidly, described casing can be provided with a refrigeration machine.
The beneficial effects of the utility model are:
1, this utility model is on the basis of original baking oven circuit, add one group of second temperature control module being mainly made up of temperature sensor, controller, relay, acoustic-optic alarm and display screen, temperature in baking oven is controlled by the second temperature control module and original first temperature control module jointly, so substantially increase accuracy and the sensitivity of monitoring, decrease the too high or too low situation of oven temperature and send alarm signal in time rapidly by the acoustic-optic alarm being provided with, inform operator on duty；
2, in work process; when the density in baking oven, the air pressure of flowing differ bigger with the air pressure of external environment condition; when being automatically adjusted by the pressure protection module arranged, the inner and outer air pressure of baking oven is in the state of stable equilibrium, it is ensured that the quality of product and the operation safety of baking oven.

Number in the figure is: 1, casing；2, heater；3, display screen；4-1, the first temperature control module；4-2, the second temperature control module；5, acoustic-optic alarm；6, temperature sensor；7, baroceptor；8, pressure release valve cylinder.
Detailed description of the invention
As shown in Figure 2 and Figure 3; a kind of baking oven with double protection functions; including casing 1 be installed on the heater 2 bottom casing 1, described heater 2 being connected to the first temperature control module 4-1, described first temperature control module 4-1 is mainly made up of temperature controller as indicated with 1 and the time relay.Being provided with a refrigeration machine on described casing 1, described cold-producing medium can be specifically the device that aerator, fan, air-conditioning etc. have cooling.Therefore, when the temperature in baking oven is too high, this utility model both can have been passed through the first temperature control module 4-1 and the second temperature control module 4-2 and directly control the cooling of heater 2, can also be undertaken the cooling in baking oven by the refrigeration machine arranged.
Baking oven of the present utility model also includes pressure protection module and for monitoring and control the second temperature control module 4-2 of heater 2 operating temperature.Described second temperature control module 4-2 includes power supply and the temperature sensor 6, controller and the relay that are sequentially connected with, and the outfan at controller is connected to acoustic-optic alarm 5 and a display screen 3, and described relay is connected with heater 2.
Described pressure protection module is installed on above casing 1; in the present embodiment; described pressure protection module includes baroceptor 7, control chip and pressure release valve cylinder 8; described pressure release valve cylinder 8 is arranged on casing 1 and is provided with for controlling the spool that pressure release valve cylinder 8 opens and closes in relief valve 8; described baroceptor 7 is connected with control chip, and described control chip is connected with spool.
During the protection module work of above-mentioned pressure; baroceptor 7 is for detecting the air pressure in baking oven and being transferred to control chip; control chip compares with the external pressure being stored in control chip after receiving this temperature; when the numerical value compared is excessive; open spool; air pressure in baking oven is discharged, when reaching safety range, controls spool and close.
These are only explanation embodiment of the present utility model; it is not limited to this utility model, for a person skilled in the art, all within spirit of the present utility model and principle; any amendment of being made, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
