Chemical Separation 950rpm Horizontal Centrifuge With Siphon Device

Product Description

GKH High Quality Chemical Separation Horizontal Centrifuge With Siphon Device

GKH siphon centrifuge is a new type of product that is developed on the basis of the ordinary peeler centrifuge. Based on the siphon principle, this product discharges the filtrate out via a siphoning device or skimming device. The filtering impetus can be changed by adjusting the liquid level at the suction inlet of the siphon pipe (skimming pipe) to further regulate the filtering rate, handling capacity, cake moisture and washing effect. A back-flushing device is configured to realize regeneration of the filter cloth and improve the separation effect. With back-flush, scouring, siphoning and other functions by configuring special devices, the filter cloth can be regenerated completely.

The siphon-type peeler centrifuge is applicable to the occasions involving large-scale production and requiring low cake moisture and sufficient washing, and therefore is commonly used for the separation of starch, sodium bicarbonate, potassium chloride, calcium phosphate and other materials. Currently, it has been widely applied in such industries as pharmaceutical production, food production, bioengineering and chemical engineering.

Technical Parameters

Operation process
Feeding
The material enters the rotating basket through the feeding pipe, and the cake layer controller controls n times of pulse feeding to fill the basket in limited manner. Usually, the material cake can reach 75-80% of the basket lip. Feeding is completed once the solid cake reaches the pre-set thickness.
 
Filtration Skimming-Filtration
The mother liquid penetrates through the filtration medium across the inner wall of the basket to complete the primary filtration, which begins as the material enters and ends as the liquid just immerses the inner surface of the solid cake. For the mother liquid containing colloid protein, the mother liquid containing the colloid protein will be removed by means of the skimming device in the course of filtration.
 
Washing
The solid cake is usually washed after the primary filtration. Add the washing liquid through the feeding pipe or washing pipe, and level of the washing liquid is monitored in the material level detector. Washing is completed once the pre-set washing load is achieved and the solid cake is immersed into the liquid.
 
Dry spinning
The basket accelerates to the high speed for drying the solid cake, and filtration is completed after the moisture content of the solid cake reaches the required value or the solid cake takes the pre-set drying duration.
 
Discharging
The solid cake is removed by the scraping device at high speed or that is decelerating, and the removed cake is discharged through the discharge mechanism. The solid phase can be discharged in two modes: discharging chute and scroll conveyor.
 
Regeneration of filter cloth
Residual solid cake can be found on the inner wall of the basket after the scraper discharges the material, the filtration basket can loosen the solid cake through the high-pressure gas on the back of the basket, and then remove the solid cake by means of the scraper device. In the siphon basket, the back washing liquid can be added into the basket from the high-level-mounted back washing tank through the suction chamber, and then reversely penetrates the residual solid cake so as to make the solid cake suspended and restore its permeability.
