Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature electric furnaces, in particular to a dew point control structure. Background Art

[0002] The existing dew point structure in the field of electronic ceramics is relatively simple in controlling the dew point of the humidification system in a high direction; however, the humidification system needs to be quickly converted to a low dew point at a certain process point in the process. The existing equipment basically uses natural cooling, and it takes more than 2-3 hours to reach the required low dew point.

[0003] In the humidification system, the dew point temperature is crucial to maintaining the comfort of the indoor environment and controlling the humidity level. If the dew point temperature is too low, the water vapor in the air will condense into water droplets, which may cause indoor humidity or condensation; if the dew point temperature is too high, the air may be too dry, affecting human comfort and health. In view of this, we propose a dew point control structure. Utility Model Content

[0004] The main purpose of the utility model is to provide a dew point control structure, which can solve the problems raised in the above background technology.

[0006] A PID controller, wherein the inner wall of the sealed boiler is fixedly connected with a PID controller;

[0008] Preferably, the handle is rotatably connected to a steam valve actuator via a connecting shaft, a steam outlet is provided on the surface of the steam valve actuator, a steam inlet is provided on the outer wall of the steam valve actuator, and the dew point temperature of the sealed boiler is calculated by a PID controller, and an output signal is sent to the steam valve actuator, thereby adjusting the dew point of the humidification system through the steam outlet and the steam inlet.

[0009] Preferably, the steam valve actuator is arranged on the inner wall of the sealed boiler, and the steam valve actuator is arranged above the heater.

[0010] Preferably, the surface of the steam outlet is provided with an automatic adjustment component, and a motor is fixedly connected to the surface of the steam outlet. The automatic adjustment component adopts a variable geometric structure. For example, when the humidity requirement is not high, the spray area increases, and when the humidity requirement is high, the spray area decreases, thereby reducing energy consumption while maintaining the humidification effect.

[0011] Preferably, the output shaft of the motor is rotatably connected to a hinged rod, and one end of the hinged rod away from the motor output shaft is hinged on the outer wall of the rotating ring. By turning on the motor, the output shaft of the motor drives the movement of the hinged rod, and the hinged rod causes the rotating ring to rotate.

[0012] Preferably, a connecting rod is fixedly connected to the lower surface of the rotating ring, and the connecting rod is slidably connected to a slide groove opened on the steam outlet surface, and the outer wall of the connecting rod is fixedly connected to a limit plate. The rotation of the rotating ring drives the connecting rod to slide in the slide groove, driving the concentrated and dispersed activities of the limit plate.

[0013] The utility model provides a dew point control structure. It has the following beneficial effects:

[0014] (1) The dew point control structure is implemented by a refrigeration system. When the dew point of the humidification system needs to be lowered, the refrigeration system starts up quickly and cools the water temperature through the cooling coil in the sealed boiler. This structure can quickly reduce the dew point of the humidification system to the set point, and even quickly achieve a point lower than the room temperature. The fast control method can make the sintering process of this electronic ceramic more precise.

[0015] (2) The dew point control structure is equipped with a dew point control auxiliary device. In order to monitor and control the indoor temperature and humidity in real time, the dew point temperature is calculated after the PID controller is operated, the required humidification amount is calculated, and the corresponding output signal is sent to the motor. The output shaft of the motor drives the movement of the hinged rod, the hinged rod causes the rotating ring to rotate, and the rotation of the rotating ring drives the connecting rod to slide in the slide groove, driving the centralized and dispersed movement of the limit plate. When the humidity requirement is not high, the spray area is increased, and when the humidity requirement is high, the spray area is reduced, thereby reducing energy consumption while maintaining the humidification effect to ensure that the water vapor content and temperature in the air reach a balanced state.
