GN SCREW PRESS AND POLYMER DOSING UNIT

GN Finished the assembly of a set of dewater screw press, and carried out factory tests. After that it will arrange to sent to overseas customers for sewage treatment in food plants.

The dewater screw press is a common sludge dewatering equipment, The dewater screw press machine is characterized by compact structure, low energy consumption, low noise and high degree of automation.many customers in the sewage treatment industry choose to use screw press for sludge dewatering. GN screw press is mainly composed of modules such as sludge flocculation cabin, dewatering screw assembly and electric control cabinet.The flocculation cabin is used to receive the original sludge and flocculants. After the flocculated sludge enters the dewatering screw, it will move towards the slag discharge port, gradually dry under the joint extrusion of the disc ring and screw, and finally discharge from the slag discharge port. The solid content of discharged mud cake is about 20%, which can meet the conditions of stacking and transportation. According to the nature of the sludge to be treated, GN is able to provide the screw press make of stainless steel 304, stainless steel 316 and even duplex stainless steel 2205 to meet customer requirements.

solid vacuum pump

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. The maximum transport capacity of the three models for clean water is 10 cubic meters, 20 cubic meters and 40 cubic meters respectively. The GN Mini Vacuum Cleaner is designed for industrial tough clean-up jobs. GN Mini Vacuum Cleaner can be used to transfer or remove fluids with high solids content. Also it can be used to remove powder material like sand and dust etc.

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.

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 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.
