Gravity Thickener

Gravity thickener is a solid-liquid separation equipment based on gravity settlement, which is similar to clarifier and sedimentation tank. It can make suspended solids in the slurry gradually sink to the bottom of the tank. Gravity thickeners are often used in mining, metallurgy and other industries to process various minerals, metals and non-metals. In addition, gravity thickeners can also be used in industrial wastewater treatment, environmental protection governance and other fields. Working principle When working, the slurry is mixed with the flocculant and enters the gravity thickener through the central cylinder. The slurry is guided from the feed vertical cylinder to the surrounding areas by the guide plate at the outlet of the feed vertical cylinder, allowing the slurry to diffuse to the surrounding areas. A gravity thickener can concentrate slurry with a solid content of 10% -20% into underflow slurry with a solid content of 45% -55% through gravity settling. With the help of a rake installed in the thickener, the thickened underflow slurry is discharged from the underflow port of the thickener. The upper layer of clear water is discharged from the top drainage outlet to achieve mud water separation. Features 1. Large processing capacity per unit volume and high concentration efficiency. 2. Hydraulic multi-point drive, infinite speed regulation, high mechanical strength, with overload protection function. 3. The hydraulic rake lifting device is used for reliable operation.

Mobile Slurry Treatment Station

The mobile slurry treatment system is a mobile sludge dewatering treatment equipment developed for the construction piling mud, river and lake dredging and other industries, which often requires the actual situation of multi-site operation. The equipment has the characteristics of high production efficiency, good working effect, convenient use and flexible maneuverability. It is especially suitable for construction projects such as bored pile foundation engineering, tunnel mud water shield, underground non-excavation. Working principle The slurry to be treated enters the lower layer of the screener through the feed pipe, and the lower screen plate (hole 5mm) sifts out the large particle material of >5mm, and the small particle material and water under the screen panel enter the water tank, then is pumped out through the slurry pump, and feeded into the high pressure hydrocyclone separator, and the separator realizes concentration and separation of the solid particles. The slurry having a concentration of about 50% flows out from the bottom outlet of the hydrocyclong, enters the upper layer of the screen machine, and the dewatering operation is completed by the upper sieve plate (hole seam 0.16 mm)to realize the slurry drying; the waste water with less than 3% suspended matter flows into the return tank through the overflow port of the separator, and is discharged through the discharge pipe. Features 1. After separation by the slurry treatment system, the sludge contained in mud water is

Thickener

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 called paste thickener. The port of the overflow is equipped with a 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 the liquid well. The concentration of pulp wastewater 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. Technology Advantages 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 the national standard of discharge and can be recycled; 8.LZZG can customize thickeners to suit individual requirements.

Filter Press

Filter press is a kind of mud treatment equipment developed for solid liquid separation in industrial production. It is mainly used in chemical, ceramic, petroleum, pharmaceutical, food, smelting and other industries, as well as industrial filtration and sewage slurry treatment. This equipment has the advantages of convenient operation and maintenance and reliable operation. The mud cake filtered by the filter press has a higher solid content and an excellent separation effect. Working principle Slurry is pumped into the filter press by high-pressure slurry pumps, the mixture flows through the filter medium (filter cloth), the solids stay on the filter cloths, forming filter cake; the filtrate exits the filter plates through the corner ports into the manifold, If it is not wanted the filtrate can be drained away for safe disposal. Features 1. The structure is simple, the operation is easy and stable, and the maintenance is convenient. 2. Less wearing parts and low maintenance costs. 3. The filter area has a flexible sele 4. Compared with other types of dewatering machines, the mud cake has high solid content, small floor space, and convenient transportation and other post-treatment.

Slurry Treatment System

NJFX Slurry treatment system is widely used in the purification and recycling of slurry for the construction of hydro power, continuous concrete wall, slurry shield tunnel, etc. This equipment is increasingly becoming a necessity of civilized construction since it not only can cut down construction cost, but also can reduce the pollution of the environment. Working principle The slurry pump sucks the mud from the mud pit, then enter into bottom layer screen of dewatering vibrating screen through buffer box, the coarse particles in the slurry are screened out and the mud flow to mud tank through the bottom layer screen of dewtering screen. The slurry pump sucks the slurry from the groove and injects the slurry with certain kinetic energy tangentially along the pipeline from the slurry inlet of the desander. The centrifugal pump takes mud from the mud tank, and feed to desander hydroyclone with pressure for centrifugal separation, the solids/sand was discharged to upper screen of the dewatering vibrating screen from the outlet nipple of the hydrocyclone. After dewatering process of the upper screen, the drier fine residue is separated out. The mud passed the upper screen returns back to the mud tank. Features 1.High mud handling capacity, sand can be removed efficiently. 2.The polyurethane screen has many advantages such as easy operation, low trouble rate, convenient installation and maintenance 3.Slag charge screened by advanced straight-line vibrating system is effectively dewatered. 4.The adjustable vibrating force, angle and mesh size of the vibrating screen enable the equipment possess a high screening efficiency. 5.Energy saving efficiency is significant since the power consumption of the vibrating motor is low. 6.The abrasion and corrosion resisting slurry pump has advantages such as advanced centrifugal designing, optimal structure, stable operation and convenient maintenance. 7.The hydraulic cyclone with advanced structural technology can efficiently separate sand from slurry. Moreover, it features in light weight, corrosion and abrasion resisting material, so it can work stably in the worst condition without maintenance.
