DB212 Series High Pressure High Temperature Package Dyeing Machine

Main features:

-         It has two dyeing modes, air pad type and full flood type to choose for different dyeing techniques.

-         Unique construction commutation (patent no. ZL200520074155.6) , the high efficiency heat exchanger and DBNP pump are combined integrative, (patent no. ZL200520074154.1). The are designed without external circulation pipes, saving space 25%.

-         Special compact designed calandria heat exchanger is installed outside, in same heat exchange conditions, it can achieve the best exchange effect of heating and cooling.

-         Main pump are controlled by stepless flowing rate of inverter, it can achieve the same dyeing effect according to different dyeing techniques, and save power consumption when starting and de-loading.

-         Special steady commutation mechanism allows liquid flow to change direction without stopping main pump, thus increasing liquor circulating times to improve level-dyeing property.

-         With multi-function intelligent computer, it simplified the water inletting, draining, eternal flowing, internal flowing, and etc. operation.

-         Pressure dewatering to decrease the water containing in package yarn.

-         Dyeing with low liquor ratio of 1:6 can save dyestuffs, chemicals, steam and water thus decreasing the drainage.

-         The high efficiency heat exchange between the liquid stream and dyeing liquor improve the speed of dyeing technique process, shorten the time.

-         Rapid loading creel, easy to take out the package, thereby reducing the labor intensity and saving the working efficiency.

Standard structure:

-         All metal parts of the dyeing machine coming into contact with the dye liquor are made of high quality anti-corrosion stainless steel.

-         High efficiency unique DBNP pump with mechanical seal mechanism are controlled by inverter (used for more than 18.5KW), the flow can be controlled stepless.

-         Vertical dyeing tank, rapid-locking lid with counterweight and  triple safety interlocking mechanism.

-         Patented automatic direction changing liquor commutation.

-         Patented unique high efficiency shell-and-tube heat exchanger.

-         Open type dosing tank and ration feeding system.

-         Main tank automatic pressure increasing and decreasing system. (air pad type)

-         Circulation liquor condensator. (full flood type)

-         High accurate pressure differential sensor to control the liquor level. ( air pad type)

-         Multi-function intelligent computer and PLC to control the feeding, water inletting, draining, temperature rising, decreasing and keeping, and the rising etc. automatically.

Options:

-         Auxiliary vessel with equal capacity for direct heating device, which is composed of feed pump and mixing system.

-         Various kinds of yarn carrier for loose fibre, hank, zipper, and yarn beam etc.

-         Hot drain.

-         Progressive dosing system.

-         Secondary water feeding and draining.

-         De-loading cones and their accessories.

-         Accessories for dyeing, such as cone, intermediate gasket and self falling tapered head etc.

-         Ejector pin type and hanging rod type package unloading device. (only for models above DB 145 serious)
