Gnp Gravity Disc Thickener

Application: Disc thickener is mainly used to wash and thicken stock in pulping and papermaking process.Its working principe is to dewater by gravity through the level difference between stock out of disc wire and white water in the disc.The pulp at the consistency of 0.8-1.2% enters the vat and then is attached to disc sector .The white water in the disc flows to the disc flows to the ends of hollow shaft through guide slot and then discharges out.Stocks attached on disc sector is knocked off by high-pressure shower.The thickened stock at the consistency 3-6%flows over the plate of adjusting valve into outlet vat where it is discharged out.The rotating speed of main shaft can be adjusted according to the required outlet consistency and capacity. Design Features: Higher efficiency and less space required. Disc sector is made of stainless steel with excellent corrosion resistance. Due to the structure of disc sector,the filtering area is large amount of white water when operating.

1. Main Function Gravity Cylinder is designed for thickening of fibrous in pulp and paper industry, i.e. chemical pulp, ground wood, waste paper, rag pulp etc. 2. Working Principle and performance Gravity Cylinder Thickener, provided with a pick-up roll, is used particularly for continuous thickening under stable input conditions. The machine capacity depends on the sort and mainly on the dewatering speed or refining rate of fibrous stock and its input consistency. This machine provides capacities ranging from 10 to 122 t/d. A dewatering drum, covered with a coagulating screen, is permanetly rinsed with washing water from shower tubs with flat-shaped jets. The input consistency is approx 0.5-1.0%, the output consistency is approx 4-6%. For more details, just feel free to contact us.

1. Strong Point Disc Thickener is maninly used for the low consistency stock thickening. The water log installation height is not needed. It can replace traditional gravity cylinder thickener. In the same floor space, the throughout of the gravity disc thickener is serval times more than that of the gravity cylinder thickener, so a lot of space and power can be saved. 2. Performance and Working Principle The pulp at consistency of 0.8-1.2% enters the vat and attached the disc sector, filtrate is guided by hollow shaft and discharged out at two end. Stock attached on sector is knocked off by high-pressure shower. The thickened stock at consistency of 3-4% flow over the plate of adjusting valve and into discharge chamber where it is out feed. The rotation speed of main shaft can be adjusted for required outlet consistency and capacity. 3. Strong Point Thickening of broke or washing of low consistency pulp systems; Compact design; Variable speed drive, very low power consumption

The xxzwn series disc thickener from dekelon, is used in the pulp and paper industry for dewatering and thickening low consistency paper pulp. Not only can this gravity thickener be used to thicken wood, cotton and straw pulp, it is also suitable for filtration and thickening applications in other industries. When compared to other types of fiber suspension thickeners and other existing dewatering and thickening equipment, our disc thickeners feature a simple structure, easy installation and maintenance, a high production capacity, wide pulp adaptability and more. They have become increasingly popular among the pulp and paper industry. According to the specific location of the drive part, the thickening machine has two arrangement modes. If the user is facing the outlet and sees the drum, and the drive part is on the right, the machine is a right hand thickener, represented by "y." on the flip side, if the drive part is located at the left, it is called a left hand thickener, represented by "z."

Gravity Cylinder Thickener Pulping Equipment Application: Used for washing and thickening low consistency pulp.   Features:  Structure is simple and operation is safe and reliable. Discharge consistency and white water consistency is easy to be controlled. Bulk degree of pulp layer forming in this equipment is high and fine impurities has stronger penetrability. So, this equipment is more adaptable to using washing method to remove such fine impurities as ink particles and ash etc.

LZZG deep cone thickener promoted the structure of internal feed tube on the basis of traditional vertical flow sedimentation tank,optimized flocculation and deep solids compression provide paste consistency underflow and higher process rates, which greatly increase settling efficiency. The deep cone thickener is circular, suspended solids settle down into bottom conical sludge tank by gravity, clear water flow away from overflow port around the upper tank, which is also calledpaste thickener. The port of the overflow is equipped with filter and baffle, which improve the water quality that poured out. Working principle LZZG thickener is a thickener tank that based on gravity and sedimentation which makes solid separate from liquid well. The concentration of pulp waste water could be enhanced from 2% ~ 15%to 60%~ 70% by the paste thickener, the clear water is overflow from the upper part of the paste thickener , so as to achieve the purpose of sewage purification, solid-liquid separation and maximum water recovery. Features & Benefits 1. LZZG thickener automatic cleaning, automatic discharge slurry, solve manual operation; 2. Following the principle of suspension filtration, media adsorption and settling, maximum purification; 3. LZZG paste thickener use qualified carbon steel (or stainless steel), the machine has good strength and corrosion resistance; 4. Low flocculant using cost, big capacity, high efficiency, stable performance; 5. Small volume, small floor space, easy installation; 6. Service life is about 15 years, low investment but remarkable economic benefit; 7. The purified water by the paste thickener can totally reach to national standard of discharge and can be recycled; 8. LZZG can customize thickeners to suit the individual requirements.
