The sealed drying box adopts modular design, flange docking, and can be assembled on site, improving the convenience of manufacturing, installation, and transportation.
Easy to disassemble and assemble, convenient for upgrading or relocation.
Adopting a fully sealed box structure, the leakage rate is low, reaching 10-5/h.
The dehumidification machine box is sealed and connected to each other through stainless steel pipes to ensure no leakage. An electric sealing valve is added to cut off the gas convection with the box when the dehumidifier is stopped.
The flow control of the dehumidifier adopts an electric closed valve+electric regulating valve structure, which is convenient for automatic control.
The outer frame of the dehumidifier adopts a fully stainless steel sealed box structure to block the entry of external air.
By installing an efficient dehumidification unit, the dew point inside the box can quickly reach -60 ° C in the initial stage.
Install a water purification system to continuously remove moisture from the interior of the box. The air supply outlet should reach near the items, and the water content in the box should be maintained below 20ppm.
Adopting intelligent control, the dehumidifier is turned off when there are no personnel working inside the box, and when someone is working but the dew point reaches -60°C, the dehumidifier runs at reduced power to reduce energy consumption.
There is a double door transition chamber with personnel and items entering and exiting the box, and the inner and outer doors do not open at the same time to block the convection of gases inside and outside.
A tool compartment has been added to facilitate the transfer of items inside and outside the box, reduce the frequency of personnel entering and exiting, and thus lower energy consumption.
An observation window has been added and equipped with a glove opening, providing a wide visual and transparent space. In case of emergency, gloves can be used.
For the lithium battery industry, transition compartments have been added at both ends to facilitate the entry and exit of various coil materials.
Adopting a sealed box structure with low leakage rate, coupled with a dehumidifier and purification system, its dew point can reach -60℃ dp, and its performance indicators are superior to traditional color steel plate assembled drying rooms. Therefore, by adopting a box sealed structure and achieving the same dew point index, the dehumidifier can be configured with lower power, which can reduce energy consumption and increase applicability.
The sealed drying box adopts an intelligent control system, with a LCD touch screen monitoring and recording temperature, humidity, pressure difference and other data. The PLC control system can achieve intelligent adjustment of temperature and humidity, reduce unnecessary dehumidifier working time, achieve energy-saving goals, and automatically alarm and display the fault location when a fault occurs. Adding an IoT module can also achieve remote control and monitoring.
The modular design of the sealed drying box greatly improves the convenience of manufacturing, installation, and transportation, and can be disassembled and assembled at will. It can be customized for customers for easy upgrading or relocation, realizing a new type of drying space production method of factory manufacturing and on-site assembly, and quickly responding to market changes. The sealed drying box can achieve rapid on-site installation and deployment, and can be quickly installed in 3-5 days without the need for on-site cutting and reprocessing. The installation is fast and does not affect on-site operations or damage the clean environment on site. The box adopts a glove box window and is equipped with an emergency glove opening, with a modern and simple design that provides a broad visual and transparent space.
Compared with traditional drying rooms, sealed drying boxs are more convenient for production line renovation, expansion, and relocation, with a high material reuse rate of over 95%, reflecting the design concept of green and energy-saving.
The dehumidifier also adopts a sealed box structure with good sealing performance, which can greatly improve the efficiency of the dehumidifier. Combined with the purification unit, the intelligent control of the electric valves set at the inlet and outlet and the regeneration return air by PLC can achieve intelligent control of temperature and humidity in the sealed drying box, greatly reducing the power consumption of the dehumidifier and achieving significant energy-saving effects.
This sealed drying box is suitable for the development of small and medium-sized testing lines for solid-state batteries, or other small and medium-sized laboratories that require drying rooms.
