2. Transition cabin

1. Oven specification: Round section, φ360*600mm, material 304 stainless steel. Equipped with sliding rail extendable transfer plate

2. Heating method: the temperature uniformity of the heating area in the heating chamber inside the heating wire is ≤±5℃

3. When the temperature is stable, the temperature difference between the heating zone in the oven and the set temperature is ≤±5°

4. Maximum heating temperature 200±5℃,

5. Temperature control instrument display accuracy: ≥±2°

6. There should be a water-cooled thermal insulation layer outside the heating cabin, and the outer wall temperature should be less than 50℃, and it should be ensured that the maintenance and replacement are convenient

7. The inner and outer doors of the heating cabin are insulated by multiple layers, and the doors are cable-stayed

8. Cabin temperature control: intelligent digital temperature control instrument, to achieve automatic uniform heating and insulation functions; with over temperature fault alarm and automatic power off function.

9. Small transition cabin φ159*300, buckle type door.

3. Control system

3.1. Mode: Including self-diagnosis, power off self-start features, with pressure control and adaptive functions. Automatic control, cycle control, password protection, vacuum chamber control using LCD display. The unit is controlled by Siemens PLC touch screen.

3.2. Pressure control: Control the pressure of the box and the transition cabin at a certain set value.

l The user can arbitrarily set the working pressure range between +25 and -25 mbar, the accuracy is ±1Pa, and the PLC will automatically adjust the pressure of the box within the set range. The default value of the operating pressure range is -1 to +3 mbar.

l When the case pressure is greater than 12 mbar, the PLC automatically opens the safety valve to relieve pressure and protect gloves, equipment and materials in the case.

l Use a foot switch to fine-tune the tank pressure.

l 3.3. Foot pedal: can control the pressure of the glove box, easy operation.

4. Circulation system (including purification and regeneration system)

Added vacuum pump start-stop time control. Vacuum pump selected British Edwards vacuum pump, model RV12, flow 12m3/h, limit vacuum 2x10-3 mbar. The transition cabin can be vacuumed separately and can be controlled separately at any time. (imported from abroad)

7. Automatic cleaning of the box

Automatic gas control plating plate; The user sets the cleaning time, and then touch the start button on the touch screen, the system will start cleaning the box, and automatically stop at the set time. Automatic case cleaning function. Different nature of the gas environment replacement and misoperation of water, oxygen fast box automatic cleaning. The box automatic cleaning valve is firmly connected to the pipe integration of the box with KF25 steel wire pipe, and the external interface is KF25 pagoda connector.

8. Organic solvent adsorption system

In order to prevent the influence of organic solvents on the purification column, a solvent column is connected in series to the glove box system, and the medium is mainly high-quality and efficient activated carbon and activated alumina to prevent the formation of hydrofluoric acid. The organic solvent adsorption system is filled with 7KG, and there is a KF40 interface on the top and bottom of the column to facilitate refueling, and the user can refueling by himself. In order to prevent the formation of hydrofluoric acid, the solvent column tank is half activated alumina.
