Gravity Thickener

Application: GNP series gravity disc thickener is mainly used in pulp-washing and thickening section of pulping and paper making industry.It is used for removal of filler and ash in pulp,for washing and thickening of pulp.It is suitable for the subsequent refining equipment and for pre-wire stock regulating system. Features: 1.Gravity disc thickener has large dewatering area,high output,small power allocation and power consumption. 2.Gravity dewatering from level difference betwwen insid and outside need no vacuum water legs.The mounting height is not require,so it will save space. 3.It use stainless steel mesh,There is no pollution.It is easy to clean and has long life. 4.It adapts to wide range of pulp,such as wster paper pulp,chemical pulp,chemi-mechanical pulp. 5.It adapts to wide range of pulp consistency from 0.8%to2.5%It uses frequency control.It can be easily adjusted.

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.

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.

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."

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

Main Parts: Sludge concentration & dewatering Body; Flocculation & Conditioning Tank; Integrate Automatic Control Cabinet; Filtrate Collection Tank Working Principle: Force-water concurrent; Thin-layer dewatering; Moderate press; Extension of the dewatering path It has solved several technical problems of other similar sludge dewatering equipment including belt presses, centrifuge machines, plate-and-frame filter press have, which are frequent clogging, low concentration sludge / oil sludge treatment failure, high energy consumption and complicated operation etc Thickening: When the shaft is driven by the screw, moving rings around the shaft move up and down relatively. Most water is pressed out from the thickening zone and fall down to the filtrate tank for gravity. Dewatering: The thickened sludge moves forward continuously from the thickening zone towards the dewatering zone. With the pitch of the screw shaft thread getting narrower and narrower, the pressure in the filter chamber increases higher and higher. In addition to the pressure generated by the back-pressure plate, the sludge is greatly pressed and dryer sludge cakes produce. Self-cleaning: The moving rings rotates continuously up and down under the pushing of the running screw shaft while the gaps between the fixed rings and moving rings are cleaned to prevent from clogging that happens frequently for traditional dewatering equipment. Product Feature: Special pre-concentrating device, wide feed solids concentration: 2000mg/L-50000mg/L The dewatering part of MSP consists of a thickening zone and a dewatering zone. In addition, a special pre-concentrating device is mounted inner the flocculation tank. Therefore, the wastewater with rather low solids content is not a problem to MSP. The applicable feed solids concentration can be as very wide as 2000mg/L-50000mg/L. Since MSP can be used directly to concentrate and dewater the low-solid sludge from aeration tanks or secondary clarifiers, the users don't have to build a thickening tank or a storage tank any more while they have to when using other types of sludge dehydrators, especially the belt filter presses. Then significant civil engineering cost and floor area are saved.

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.
