Detailed Description
The invention is described in further detail below with reference to the embodiments of the drawings.
The steam generating device for the steam box shown in fig. 1 and 2 comprises a steam generator 2, wherein an electric heating element 1 is arranged at the bottom of the steam generator, a steam outlet is formed in the steam generator, a pressurizing device with a steam inlet and a steam outlet is arranged on the steam generator, the steam inlet of the pressurizing device is communicated with the steam outlet of the steam generator, and the steam outlet of the pressurizing device is communicated with a steam box liner 3.
In this embodiment, the pressurizing device includes a container 4 having a flow passage 11 therein, a piston 5 movably disposed in the flow passage and reciprocally movable along the flow passage, and a driving mechanism for driving the piston 5 to reciprocally move in the flow passage; the steam inlet of the supercharging device is communicated with the flow passage; the driving mechanism comprises a spring 6, a nut 7, a screw rod 8 and a motor 9, wherein one end of the spring 6 is connected with a piston, the other end of the spring 6 is connected with the nut 7, the nut 7 is in threaded connection with the screw rod 8, the screw rod 8 is connected with the motor 9 and is driven to rotate by the motor, a guide rod 10 which plays a guiding role in the movement of the nut is arranged in a flow passage, the motor 10 is connected with a control component 12, a temperature sensor 13 is arranged in the steam box liner 3, and the temperature sensor 13 is also connected with the control component 12.
The steam generated in the steam generator directly enters the steam box liner after passing through the supercharging device, and the steam in the steam box liner is finally discharged into the atmosphere through the air outlet, so that if the steam generator works under the standard atmospheric pressure P0 of the environment at the moment, the steam at the temperature of 100 ℃ can be generated at the moment.
After the steam generator is filled with steam in the steam box inner container, the temperature of the steam can be detected by the inner container temperature sensor arranged in the steam box inner container, as the steam is filled with the steam box inner container for a certain time, after a period of time T0 is required, the inner container temperature sensor in the steam box inner container detects that the temperature of the steam reaches a stable value T0, when the ambient atmospheric pressure Pe is less than the standard atmospheric pressure P0, T0 is less than 100 ℃, in order to obtain the nut of the higher steam temperature supercharging device, the nut moves leftwards along the screw rod under the driving of the motor, as shown in fig. 2, the spring compresses to generate a certain pressure Pt, at the moment, the internal pressure of the steam generated by the closed steam generator is increased and pushes away the piston, at the moment, the temperature of the generated steam is higher than T0, and the temperature T of the steam can be detected after the temperature detected by the temperature sensor is stable for a certain time and the like. While the detection system can detect the distance deltax by which the nut is moved to the left. If the temperature T of the water vapor can not reach the required temperature, the motor drives the screw rod to rotate to transfer the nut to move leftwards continuously, the pressure of the spring is increased, and accordingly higher vapor temperature is obtained, and whether the nut moves leftwards or rightwards is determined by repeatedly detecting the temperature of the inner container temperature sensor.
