Embodiment Construction

[0060] figure 1 A centrifugal separator 100 according to an embodiment of the present invention is shown in. The centrifugal separator 100 includes a cylindrical separator drum 110, preferably a common tubular drum with a relatively small diameter D and a long length L such that the ratio of L / D is about 5 / 1. For example, a separator drum 110 with a drum diameter of 500 mm and a flow rate of 100 liters / minute can be used, so that a sufficient rotational speed can be obtained at the inner surface of the separator drum 110 to produce from 20,000 grams to 30,000 grams. Separation force. For similar combined area and gravity, the tubular drum is superior to other known cylindrical drums in terms of cost and performance, such as the "basket" type centrifugal separator drum. For example, because the radius of the tubular drum is smaller, the peripheral speed is lower, which reduces wind resistance, friction, and heat generation. Likewise, the longer length of the tubular drum results ...

Abstract

A centrifugal separator (100) is provided which includes rotatable separator bowl (110), which is selectively rotatable and supported by a hollow shaft spindle (130). A scraper and feed assembly (120) including a plurality of scraper blades (122) is supported by the shaft spindle (130) within the separator bowl.

Description

[0001] Related application [0002] This application claims the priority of provisional patent application No. 60 / 223,409 filed on August 4, 2000 and utility patent application No. 09 / 896,551 filed on June 29, 2001 in accordance with 35 U.S.C. §119(e). Technical field [0003] The present invention generally relates to a centrifugal separator, and more specifically, to a centrifugal separator capable of automatically discharging solids from the separated centrifugal filtrate. Background technique [0004] As we all know, many different types of centrifugal separators separate multiphase mixtures based on "their specific gravity composition". The multiphase mixture is injected into the rotating drum of the separator, the mixture may also be referred to as conveying material or liquid feed. The rotating drum rotates at a high speed and forces the particles of the mixture to separate from the liquid centrifugal filtrate (purification liquid). Therefore, a dense solid block is pressed...
