Description

Technical Field

[0001] This invention relates to the field of mold testing technology, specifically to an anti-condensation ultrasonic humidification device for a mold testing chamber. Background Technology

[0002] A mold test chamber is a key testing device used to simulate a high-temperature and high-humidity environment to assess the anti-mold performance of products or materials. In such tests, it is usually necessary to maintain the environment inside the chamber at a stable high-temperature and high-humidity state for a relatively long period of time. In order to create and precisely control such a high humidity environment, the humidification device is one of the core subsystems of the mold test chamber. Ultrasonic humidification technology is widely used in testing equipment with stringent humidity control requirements due to its high humidification efficiency, fast response speed, and precise control.

[0003] However, when introducing and evenly distributing high-humidity air into the test chamber, it is necessary to overcome the condensation problem caused by temperature differences. Condensation can not only interfere with the test and contaminate the samples, but may also affect the measurement accuracy and operational safety of the equipment sensors. Therefore, developing a humidification device that can stably provide high-humidity air and effectively prevent condensation is of great significance for ensuring the reliability, accuracy and safety of mold tests.

[0004] In existing technologies, a common solution to address condensation issues is to install a high-power heater directly inside the mold test chamber. When a local surface temperature is detected to be too low or there is a risk of condensation, the heater is activated to heat that area. However, heating inside the test chamber to compensate for the cooling load introduced by humidification and to raise the temperature of various internal surfaces significantly increases the burden on the main temperature control system of the test chamber, causing fluctuations and unevenness in the internal temperature field. Furthermore, this additional heating within the sealed test space forces the refrigeration system to start more frequently to maintain temperature stability, creating an energy-consuming cycle of "refrigeration-heating-re-refrigeration," leading to reduced overall energy efficiency and higher long-term energy costs.

[0034] By using the heating box 5, the serpentine tube 23, the electric heating plate 22 and the temperature controller 21 together, the effect of precise heating and anti-condensation pretreatment of the humid air in an external independent unit is achieved before the humid air enters the conveying pipeline of the mold test chamber.

[0035] By using the filter roller 13, motor 10, gear 11, gear ring 12 and brush roller 16 in combination, the effect of dynamic filtration of humidifying water and automatic online cleaning of filter screen is achieved.

[0036] Working principle: First, external water enters the second serpentine pipe 29 of the recovery tank 26. As it flows through the second serpentine pipe 29, it absorbs the high-temperature waste heat generated by the refrigeration equipment of the mold test chamber recovered from the hot air pipe 30 and its heat-conducting fins 31 inside the recovery tank 26, thereby preheating the cold water. The preheated water is then transported to the fixed plate 4 through the first corrugated pipe 27 and the water inlet pipe 28, and sprayed onto the inner wall of the rotating filter drum 13. After being filtered by the drum, the water falls to the bottom of the humidification tank 1. The liquid level sensor 33 in the humidification tank 1 monitors the water level in real time. The main controller 32 controls the power controller 18 to supply power to the ultrasonic atomizing plate 19 according to the settings, so that it atomizes the filtered water. The generated clean water mist rises directly and enters the air outlet pipe 24 and the second corrugated pipe 25. The serpentine tube 23 of the heating chamber 5; at this time, the temperature sensor 15 monitors the ambient temperature and transmits the signal to the temperature controller 21. The temperature controller 21 controls the electric heating plate 22 to work, precisely heating the humid air in the serpentine tube 23 to increase its temperature and reduce the relative humidity, thereby preventing condensation from forming in the conveying pipeline and the mold test chamber. The uniform humid air, after being heated and treated to prevent condensation, is finally stably output from the outlet of the serpentine tube 23 to the mold test chamber. In addition, the brush roller 16 at the bottom of the fixed plate 4 continuously brushes the inner wall of the filter roller 13 when it rotates to prevent the filter screen from clogging. The electric push rod 8 can drive the horizontal plate 7 and the fixed ring 2 to rise and fall as a whole, thereby driving the filter roller 13 and the brush roller 16 to rise and fall to adjust the filtration and cleaning position.
