Abstract
The utility model discloses a safety device for a heating drying oven, which comprises a heating box, the heating box is provided with a fan, the fan is connected with a motor, a speed sensor is arranged on a shaft of the fan and connected with a PLC (programmable logic controller) unit, and the PLC unit controls the heating box. The shaft of the fan is provided with the speed sensor, therefore, the speed sensor can transmit the rotation information of the fan to the PLC unit all the time, and control a heating system to heat the heating box after processing of the rotation information by the PLC unit; and simultaneously, a temperature sensor at the upper part of the heating box can transmit the information of change of temperature in the heating box to the PLC unit all the time, and control the heating system after processing of the temperature change information by the PLC unit. The safety device realizes monitoring of the fan and the temperature control. simultaneously, the safety device is also provided with an alarm unit; and when the fan or the heating box works abnormally, the PLC unit processes the problem firstly, and then controls the heating system and gives an alarm simultaneously, thus effectively improving the safety protection capacity of the equipment.
Description
Technical field
The utility model relates to a kind of heated oven, relates in particular to a kind of safety device of heated oven.
Background technology
Oven heat is the critical facility of intaglio press, and the structure of oven heat is by heating tube, surely control the temperature control system that instrument, blower fan are formed a closed loop jointly.Under normal circumstances, temperature of oven is controlled by steady control instrument, and precision can reach positive and negative 0.1 ℃.But in actual use; because the sky of fracture of the V-belt of blower fan and motor transmission or blower fan is opened escape, all can cause interlock protection ineffective, causes blower fan not move and the lasting heating of heating tube; because the heating cabinet heat can not in time discharge, and causes security incident after heating cabinet is overheated.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency a kind of heated oven safety guard is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of heated oven safety device comprises heating cabinet, and heating cabinet is provided with blower fan, and blower fan links to each other with motor, on the blower fan axle velocity sensor is set, and velocity sensor is connected with the PLC unit, PLC unit controls heating cabinet.
Above-mentioned heated oven safety device is provided with temperature sensor on the top of heated oven, and temperature sensor is connected with the PLC unit.
Above-mentioned heated oven safety guard also is provided with alarm unit in the PLC unit.
Adopt technique scheme, the utility model has following advantage: because the blower fan axle is provided with velocity sensor, can be constantly the rotation information of blower fan be sent to the PLC unit, by control heating system after the PLC cell processing heating cabinet be heated.Temperature sensor on heating cabinet top can constantly be sent to the PLC unit with the temperature information in the heating cabinet simultaneously, by controlling heating system after the PLC cell processing.Realize blower fan and two monitoring of temperature control.The PLC unit also is provided with alarm unit simultaneously, and is unusual if blower fan or heating cabinet occur, and the control heating system is reported to the police simultaneously after the PLC cell processing, has improved the safe precaution ability of equipment effectively.
Description of drawings Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of heated oven safety device as shown in Figure 1 comprises heating cabinet 5, and heating cabinet 5 is provided with blower fan 4, and blower fan 4 links to each other with motor, and velocity sensor 3 is set on the blower fan axle 7, and sensor 3 is connected with the PLC unit.Be provided with temperature sensor 6 on the top of heated oven, temperature sensor 6 is connected with the PLC unit.Also be provided with alarm unit in the PLC unit, PLC unit controls heating cabinet 5.
Claims (3)
