solids vacuum pump

GN Solids Vacuum Pump is a pneumatic vacuum pump widely used for solids, mud, slurry, liquid waste transfer. The vacuum is up to 85 Kpa/25 inch HG（Mercury Column）,the discharge distance is over 500 meters.

GN solids vacuum pump is completely pneumatic conveying equipment. Its working principle is to empty the inside of the equipment through an external air source to form a negative pressure. After the transported material is sucked into the equipment, compressed gas is introduced to discharge the material. GN solids vacuum pump has a wide range of applications and can transport liquid, slurry with high liquid content, sludge with high solid content and loose solid particles and powder.

GN solids vacuum pump has three models, namely GNSP10B, GNSP20B and GNSP40B.

GN solid vacuum pump has obtained European CE certification and ATEX explosion-proof certification, and can be imported to Europe smoothly and used safely in explosion-proof areas.

disc stack separator

Disc stack separator is a kind of vertical centrifuge, The drum is installed on the upper end of the vertical shaft, and is driven by motor through the transmission device to rotate at high speed. Inside the drum there is a set of disc-shaped parts which are overlapped with each other, And the inner drum is a set of disc-shaped parts, which are nested and folded together. There is a small gap between the discs. The suspension is added to the drum by the feed pipe at the center of the drum. When the suspension flows through the gap between the discs, the solid particles or droplets settle on the discs under the action of the centrifuge to form sediment or liquid layer. The sediment slides along the surface of the disc and separates from the disc and accumulates in the place with the largest inner diameter of the drum. The separated liquid is discharged from the outlet of the drum. The function of the disc is to shorten the settling distance of solid particles or droplets and expand the settling area of the drum. The disc installed in the drum greatly improves the production capacity of the separator. The solid accumulated in the drum shall be removed manually after the separator is shut down, or discharged from the drum without shut down through the slag removal mechanism.

33332 Phase Disc Separator

We GN separation company provide 2 phase disc stack separator (Liquid solid separation, separation of bottom concentration suspension, which is called clarification operation). and 3 phase disc stack separtor(Liquid-liquid separation or liquid-liquid-solid separation, the separation of emulsion is called separation operation )

 

 

2 phase and 3 phase decanter centrifuge

Hebei GN separation & conveying equipment Co.,Ltd manufacture industrial separation equipment and converying equipment. Decanter centrifuge is one of the main products of us, GN centrifuge production line is from 9 inch bowl to 30 inch bowl,with bowl length and diameter ration up to 4.2, and the adjustable G force is up to 3000G to meet different industry separation applications. And the types of decanter centrifuge include: clarifying centrifuge, classifying centrifuge, thickening centrifuge, dewatering centrifuge.

GN decanter centrifuges help you separate solids from liquids within one single continuous process. And we have 3 Phase decanter centrifuge and 2 phase decanter centrifuge, for 3 phase decanter centrifuge is different from the 2-phase decanter centrifuge, it is used for separation of
mixture of solids and two types of immiscible liquids and solids.

It adopts the electrical dual-motor driving system. 3 phase liquid-liquid-solid Decanter centrifuges, also called tricanter, Taking advantage of the principle that the heavy liquid, light liquid and solid phase, with different density and mutually insoluble in the mixed liquid, gain different sedimentation speed in the centrifugal force field or gravity force field, separating stratification or causing the solid particles in the liquid to deposit can be achieved. It is the popular machine throughout the world and widely used in the crude oil separation. The main motor is driving the bowl and the back motor is driving the screw via pulley device. This model is equipped with a VFD control cabinet. Inside the control cabinet, there are 3 VFDs for main motor, back
motor and the feeding pump. GN 3-phase decanter centrifuge is equipped with lube oil circulating system for the main bearing lubrication. This real time lubrication system ensures the stable running of the machine.

GN 3-phase decanter centrifuge has a widely application like plant edible oil production, kitchen waste treatment, etc.

Decanter Centrifuge Manufacturer in China

Compared with other separation machines, centrifuges can not only obtain solid phase with low moisture content and high-purity liquid phase, but also have the advantages of small size, good sealing, continuous operation, automatic remote control, etc., so they are widely used in chemical industry, Petrochemical, petroleum refining, light industry, medicine, food, textile, metallurgy, coal, mineral processing, shipbuilding, environmental protection, military and other departments, such as the recovery of pulverized coal for wet coal mining; the purification and reuse of drilling mud for oil mining; uranium Concentration of isotopes; sludge concentration and dehydration of sewage treatment; refining of petrochemical products; extraction of antibiotics and pesticides; manufacture of milk, yeast, beer, fruit juice, sugar, orange oil, animal and vegetable oil, rice bran oil, starch and other foods; The dehydration of fabric fibers; the purification of lubricating oil and fuel oil need to use centrifuges. It can be seen that the centrifuge has become widely used separation equipment in various sectors of the national economy.

The application functions of the centrifuge mainly include: dehydration, clarification, concentration, classification, separation and so on. Different centrifuge models must be selected according to different material characteristics and separation requirements, which leads to the problem of centrifuge selection. In the actual production process, due to the selection of suitable separation equipment for some projects, the process is simple, the energy consumption is reduced, the product quality is improved, and good economic benefits are obtained; but there is also improper selection of centrifuges, which makes the production process unable to proceed normally. , resulting in greater economic losses. Therefore, in the engineering design and technical transformation, the problem of how to correctly select the centrifuge has been recognized and valued by the majority of engineering and technical personnel.

GN Company’s Decanter Centrifuge for Wastewater Treatment

GN Company has been focus on manufacturing Decanter Centrifuge for about 10 years. Now it has three factories in China Mainland, and two subsidiaries outside China, one is in the USA, and the other one in Russia.

GN Technical Engineers have rich experience on research and develop the centrifuge technology, and here are some of their experience about analysis and elimination of abnormal problems.

1. The separation liquid is turbid, and the solid recovery rate is reduced. The reasons and solutions are as follows:
(1) If the thickness of the liquid ring layer is too thin, the thickness should be increased.
(2) The amount of mud entering is too large, and the amount of mud entering should be reduced.
(3) The speed difference is too large, and the speed difference should be reduced.
(4) The inflow solids are overloaded, and the amount of mud entering should be reduced.
(5) The screw conveyor is seriously worn and should be replaced.
(6) The rotating speed of the drum is too low, and the rotating speed should be increased.

2. The solid content of the mud cake decreases. The reasons and solutions are as follows:
(1) The speed difference is too large, and the speed difference should be reduced.
(2) The thickness of the liquid ring layer is too large, and its thickness should be reduced.
(3) The rotating speed of the drum is too low, and the rotating speed should be increased.
(4) The amount of mud entering is too large, and the amount of mud entering should be reduced.
(5) The dosage of dry sludge should be reduced if the dosage of conditioning and tempering is excessive.
