GKH AUTOMATIC SIPHON HORIZONTAL SCRAPER CENTRIFUGE

Features & Uses of  Automatic Horizontal Scraper Centrifuge:

This screen centrifuge is controlled by PLC and regulates the speed by frequency convertor. The braking system of continuous centrifuge applies dynamic braking and regenerative braking, the whole separation process is an automatic circulative process and the manual operation mode is applicable to be changed over from automatic operation mode.

GKH Series automatic siphon centrifuge is more suitable for separating such products as small solid-phase granularity and which is hard to be separated. It is widely used in the pharmaceutical, chemical, and foodstuff industries (e.g. starch, calcium phosphate, sodium bicarbonate).

Centrifuge is a separation machine which achieves solid-liquid separation by the centrifugal force. It runs continuously with interval discharging. The feeding pipe starts to feed when the drum revolves at a certain speed. At this time, the siphon pipe locates in a certain area of the siphon room. The product will be sprayed evenly on the drum wall through the feeding pipe while the filtering liquid will be drained into the siphon room through the filtering net, mesh and the holes in the drum bottom.Then the filtering liquid will be extracted outside through the siphon pipe. The solid will be left on the filtering mesh. After a period of spinning, the scraper will move to peel down the products from the drum wall and enter into spiral discharging device and then go to outside.

 

SIPHON CENTRIFUGE MAIN CHARACTERISTICS

This kind of centrifuge consists of a drum, scraper system, siphon system, skimming system, back flushing system, bearing seat, transmission system, floating platform (prepared by the user), controlling system and etc. The shell and connecting plate are welded together, with strong intensity. The centrifuge can be installed wholly on the floating platform by connecting terrace, which will is steady and disassemble. And there are damping shock absorbers installed at the bottom of the platform. 

This type has high performance in separating suspensions with the cake density of 0.8~2.5, particle size of 0.05mm~1mm and solid concentration of 15%~80%.

It has been widely applied in the chemical, food, pharmaceutical, light industry and other industries for separating such
materials as sodium bicarbonate, caustic soda, starch, boric acid, ammonium sulfide, sulfuric acid, sodium sulfate, ferrous sulfate, calcium phosphate, polyvinyl chloride, sodium chloride, and potassium chloride.

GK Horizontal Batch High Capability Automatic Peeler Filtration Centrifuges

• Control mode: PLC control, with touch panel and human-machine interface and supporting electric-hydraulic actuator to realize automatic remote control.
• Multiple safety protections: speed detection, overvibration protection, cover opening protection, overload protection,
overtemperature protection, peeler action protection, nitrogen protection, electromagnetic interlocking, etc.
• Discharge mode: open discharging through chute or integrated discharging with peeler conveyed through spiral.
• Hydraulic coupler can be adopted for the transmission of models below GK1250 to realize stable startup, simple control and effective overload protection of motor.
• Variable-frequency control, dynamic braking or energy feedback braking, stepless regulation of speed are designed to realize energy saving, environmental protection and more reliable operation.
• Optional configurations: online washing system, nitrogen protection system, steel platform, hydraulic locking device, etc.
GK series peeler centrifuge is widely used in such industries as chemical, food, light industry, pharmaceutical, starch, etc. It is suitable for separating suspension containing large-size or medium-size or small-size particles, such as sulphuric ammonia, carbonic ammonia, PVC, modified starch, etc.
GKH series Siphon peeler centrifuge is designed on the common peeler centrifuge basics. By the siphon to increase the force pushes the clarified liquid passing through the filtration medium into the liquid chamber. The liquid is drained out of the basket through the sucker. Adjusting the position of sucker could change the liquid level in the suction chamber to adjust the force of filtration, speed, output, the dryness of the solids cake and the effectiveness of cleaning.Because of siphon function, GHK series centrifuge has larger pushing force in filtration, in treating materials with high viscosity, its moisture content of filter cake can be lower than that of GK series. Set a recoil fitting. Pour washing liquid into the suction chamber and the overflow chamber if it needs. Washing liquid flowing into the drum will resume the filtering performance of the filtration medium when it passes through it.Siphon peeler centrifuges are suitable for massively processing of the highly sticky slurry with free moisture solids cake. It can be applicable to separating amylum, sodium bicarbonate and calcium phosphate.

Working Principle ( Show in below diagram ).

Horizontal peeler centrifuge is a new type of high-efficiency automatic centrifuge, which uses the strong centrifugal acceleration when the centrifuge rotates at high speed to dehydrate and wash fully.

The suspension enters into the high-speed rotating filter basket through the feed valve, and the feeding process is controlled by time or material controller until the basket is allowed to be fully filled.In the feeding process, the mother liquor is filtered through the filter cake layer and filter cloth, and then discharged out of the machine through the discharge pipe through the small hole casing of the basket body.The washing liquid is controlled by the time or flow valve, and the washing liquid is sprayed on the filter cake through the washing pipe and the spray hole to wash the filter cake after removing the mother liquor, so as to obtain the solid phase meeting the requirements.After drying, the cake layer is cut by the rotary scraper and sent out of the machine by the inclined bucket or screw conveyor.These processes can be completed manually or automatically by electrical, hydraulic and mechanical operations.

This series of centrifuges work smoothly, especially suitable for heavy load production and the solid phase needs to be fully washed, as well as low solid content, fine crystallization, high separation requirements of special occasions.

Types of  Discharging 

There are two kinds of type for solid cake discharging , One is hopper discharging , and the other is screw conveyor discharging .

 

 

Main Characteristics

1.This centrifuge adopts speed regulation by frequency convertor and PLC control, friendly human-computer interface and electric hydraulic (pneumatic) device. Monitoring can be executed in overall processes such as feeding, initial filtering, washing, secondary filtering and discharging etc. which embodies automatic operation without operator, so human-machine conversation can be realized with convenient use and maintenance.

2.Frequency speed regulation system is adopted to ensure stepless speed regulation, while dynamic braking(or regenerative braking)is adopted to ensure stable operation. There is also perfect protection system, product level detection, speed inspection, vibration protection, interlock protection for machines opening over heating protection for motor and scraper motion protection all of which make it safer for operation.

3.Adopted whole sealing sex-proof structure, the centrifuge has automatic air exchange system (according to oxygen content content or protective gas pressure) or inert gas protection, so it can meet the demand of GMP Norm of pharmaceutical industry and solid-liquid separation of flammable and explosive products.

4.Welded structure is adopted on the shell to ensure a tight form and high intensity but light weight.

5.Inner surface is polished and no dead angles are left. Connection parts, welding seam, corner and edge adopt round and smooth treatment. Equipped with CIP system (product and machine cleaning) to get a optimized washing effect.

6.The automatic residual cakes removing device is optional (have owned the national patent)

Application

It is not only used for medium and fine particle contained suspension's separation, but also used for the solid-liquid separation of noxious, explosive and combustible product.

It adopts indined hopper or screwed conveyor to discharge solid product.

It is mainly used in solid-liquid separation of raw materials, intermediates and end products in the fields such as pharmaceutical industry and chemical industry.
