OUR LATEST INVENTION:
Automatic inversion welding production line for large size tank
The production lines are being benefits of the latest r&d and manufacturing for large size tank
automatic seam welding, coating, drying. This production line is designed to discard many of
drawbacks of similar products to break through the bottleneck of the design constraints, a bold use
of advanced design, makes the production line from the weld quality, production efficiency,
energy saving and environmental protection, appearance, in all respects to be the forefront of the
large size tank welding machine, marked the direction of welding equipment in domestic. Once
the products enter the market immediately favored by many can equipment factories.
GHG-300 high frequency induction drying machine/drier
The advantages of High-frequency induction drying method:
1: Energy saving
Statistics condition: count by the most conservative condition, supposing the annual production
time is 200 days, working 16 hours per day, the electric price is 0.8 yuan per kilowatt (in China),
to meet the energy requirements of equipment with the capacity of 300cans/min.
Energy consumption of drying by tubular electric heating element: 700 watts each heating tube,
six tubes on each electric heating boxes, every drying machine possesses 9 electric heating boxes,
the annual energy consumption is:
700 Watts X 6 tube / degree X 16 hours/ day X 9 degrees X 200 days = 120960 kwh
0.8 yuan / kwh X 120960 kwh = 96768 yuan
Energy consumption of gas drying: According to industry statistics, the average level of energy
consumption by gas drying is the tow-third of electric drying consumption , so under the same
conditions. gas drying annually costs:
96768 yuan X 2 / 3 = 64512 yuan
Energy consumption of high-frequency drying: We design high-frequency induction drying
machine with installed capacity of 50KVA. But the actual operation consumes only 5 kWh per
hour. To design like this is order to extend equipment life, and to prevent overload avoiding
impacting the equipment operation, such a design, just increase our company's manufacturing
costs and will not affect the user’s cost control. Energy cost per year by high-frequency drying:
0.8 yuan / kWh X 5 kWh / hour X 16hours X 200 days = 12800 yuan
relative to the electric tube drier, high-frequency drier annually saves:
96768 yuan - 12800 yuan = 83968 yuan
relative to the gas drier, High-frequency drier annually saves:
64512 yuan - 12800 yuan = 51712 yuan
Statistics above were calculated based on conditions of the industry's most conservative conditions,
the actual operating time is longer than the time calculated above, the saving effect is more
The hot air distribute while electric heating, the temperature of the workplace rise, volatile liquids
like solvents (thinner) was blown by hot wind, the smell of solvent exudes and affect the working
Gas is not 100% complete combusted while gas drying, part of the gas evaporate, the workplace is
full of heavy gas smell, workplace temperature rise, so the staff are not able to adapt to the
environment, it also affect human health causing that recruitment is difficult.
High-frequency drying adopts regular position sense heating, use internal heating methods, no
need heating media, the workplace temperature close to room temperature, no peculiar smell of
volatile solvent. Our equipment detected by Shantou Environmental Protection Bureau, radiation
is well below national safety standards.
3: Other aspects
Electric dryer occupy more than 10 meters, heating pipes need regular maintenance. Gas dryer
need to configure the gas bottle, not only takes up space, but also there is a certain security risk.
And high-frequency dryer is only 8 meters, with compact aesthetic appearance. The two conveyor
belts are designed as “V” model, delivering cans smoothly, have high durability. In order to insure
the can translating from coating machine to high-frequency dryer smoothly and stably, we
specially designed magnetic transfer mechanism, replacing the two round tape . In addition, to
make sure the can finishing dried well to transfer into the next process under control, our dryer
specially configured speed accelerating and separate device for can body, to prevent rear-end and
blocking phenomenon. The whole drying machine is lift and down by hydraulic mechanism. It is
also assembled by defective product test and separate mechanism to ensure no defective product to
