Product Performance

One-time drying of the plate is about (3500-4000), large pieces (thickness less than 2.2 mm)
Convenient discharge of the plates: the plates are taken out from the forming tank to typesetting, cleaning and drying can be done at one time.
It adopts American and Japanese original brand parts to control, so that the flame of the combustion system can be accurately controlled.

Performance characteristics after drying

Without adding any chemical antioxidants, the moisture content can be less than 0.1%, and lead oxide can reach less than 3%.
The negative plate is dry and does not oxidize, and the lead content is high and the supplementary power is within 3%.
The dry anode plate adopts 0℃ so that the material of the electrode plate is not softened, and the potential of the assembled battery is high after acid is added, which is extremely surpassing the starting performance and the service life of the battery.

Comparative analysis of WEISH fast plate anaerobic dryer and semi-open drying tunnel

Name/Project	WEISH Weixu Fast Plate oxygen-free dryer	Semi-open drying tunnel
Use space	It takes up little space	It occupies a large space and the working range exceeds 23 meters.
Heating fuel	Liquefied petroleum gas, natural gas	Electric heating, steam, liquefied gas or other (fuel oil)
Drying performance	Closed circulation of oxygen-free hot air to save energy	Using a semi-open type, heat loss, waste of energy
Drying energy consumption	110 thousand kcal/hour, power consumption 26KW/hour	180,000 kcal/hour, power consumption 31KW/hour
Operation Manpower	One person can operate 2-4 units at the same time	One machine requires more than 2-3 people to work continuously at the same time
Operation	After being collected by the chemical conversion tank, it is directly discharged into the drying rack, cleaned and dried. It is extremely convenient to discharge various types of plates	It is collected from the formation tank and put into the water tank. It is not easy to clean. During the drying process, the electrode plates are easy to fall, deform and lose a lot, and it is troublesome to adjust and dry the various types of electrode plates.
Use space	It takes up little space	It occupies a large space and the working range exceeds 23 meters.
Operating temperature	The negative plate is dried at a low temperature of 115-120℃, and is automatically controlled at a constant temperature, so that the grid maintains the original alloy strength	The drying temperature is above 150℃, which will anneal and soften the grid alloy and affect the original mechanical strength of the grid.
Dryness and quality	After being formed, it is directly discharged into the rack and cleaned, and then hung into the fast plate oxygen-free dryer to dry. The whole process is carried out under automatic constant humidity and constant temperature drying conditions, so that the moisture content does not exceed 0.1%. Lead oxide is generally acceptable. Press to control around 1.5~3%	After the formation, it is generally necessary to heat and soak the flame retardant before drying, and the semi-open drying is difficult to control the temperature, the oxygen changes greatly, and the moisture content of the electrode plate reaches 3%, and the lead oxide reaches 8%
Plate performance	Dry load performance, after adding acid for 3 minutes, you can start using	It takes 8 minutes (good) to 35 minutes (bad) to start use
Use and maintenance time	The main parts are all made of (304#) stainless steel, which is not easy to damage and corrode. Long-term normal use, only need to replace some electrical parts, more than 25 years of time	Made of general metal. Corrosion is fast, and all movable parts are easily damaged. Corrosion and rust have a certain pollution effect on the pole plate. After long-term use, the main body corrodes quickly, and the parts are worn out. It is difficult to use normally in 6-10 years.
Development trend	Used in advanced areas such as the United States, Europe, Southeast Asia, etc. Now many well-known domestic battery companies and manufacturers have switched to fast plate anaerobic dryers for plate processing, with good product quality and high brand reputation	Many domestic manufacturers are using it, but the product quality is only maintained at a general level, the quality of the plate cannot be improved, the brand reputation is low, and it cannot be upgraded to a higher level of quality.

Illustration of the basic principle of anaerobic dryer

Use coal gas (liquefied gas) or natural gas as fuel gas

A 22KW high-pressure circulating fan blows high-temperature inert gas through the pole plate to dry the pole plate without oxygen

The plates are quickly loaded into the dryer by crane five layers at a time

Generate high-temperature oxygen-free inert gas through precise combustion control

The drying process is completely controlled by the electric control center

Cold water enters the furnace for dehumidification, and the hot water is pumped back to the cooling tower for heat exchange

Reasonable water-cooling automatic control thermal efficiency is raised to the limit, effectively achieving energy saving and time saving

The plate is placed in the stainless steel frame and used for loading, unloading and cleaning with a crane. One person can complete the entire mechanized operation

Simple operation flow chart of anaerobic quick drying machine

The plate assimilated into the tank is taken out and placed directly in the plate rack of the water tray cart, and then lifted into the washing tank by a crane for cleaning. After washing, it is hoisted into the drying tank to be sliced.
