Description
Technical Field
[0001] The utility model relates to the technical field of scraper type centrifuges, in particular to a residual filter removing mechanism of a scraper type centrifuge. Background Art
[0002] The scraper unloading centrifuge can automatically realize the processes of feeding, separation, washing, dehydration, drainage, unloading, and screen washing at full speed. It has the characteristics of novel structure, stable operation, high degree of automation, low labor intensity, large production capacity, good washing effect, and low moisture content of filter cake. It is suitable for separating suspensions with solid particles larger than 0.015mm and concentrations ranging from 25-60%. It is suitable for solid-liquid separation in chemical, food, pharmaceutical and other industries, such as starch, citric acid, amino acids, etc.
[0003] The main motor of the scraper unloading centrifuge drives the inner and outer drums of the set to rotate at full speed. The material is introduced into the drum through the feed pipe. Under the action of centrifugal force, the liquid phase passes through the filter cloth and the filter holes on the inner drum wall and is discharged from the inner drum. It is collected in the gap between the inner and outer drums, passes through the through hole to the siphon chamber and enters the siphon chamber, and then is sucked out of the machine by the siphon device. The solid phase is trapped in the inner drum to form an annular filter cake layer. When the feed reaches the predetermined volume, the feed is stopped for further separation. At this time, washing can be carried out. After washing and separation, the scraper scrapes the solid phase and discharges it out of the machine.
[0004] In order not to affect the centrifugal rotation of the drum, there is a certain gap between the scraper of the current scraper centrifuge and the drum wall, which results in a poor effect of the scraper on the removal of residues attached to the inner wall of the drum, and the efficiency of removing residues only by the scraper is not high enough.
