Abstract

The invention discloses a protection device and a protection method for a filtering rotary drum of a centrifugal machine. The protection device comprises special-shaped protection sleeves positioned in filtering holes of the filtering rotary drum of the centrifugal machine, a filtering hole protection sleeve is arranged in each special-shaped protection sleeve, the shape, size and thickness of each filtering hole protection sleeve are matched with those of the filtering holes, the filtering hole protection sleeves are embedded in the filtering holes, the area of each special-shaped sheath is larger than and can only cover one filtering hole, and is attached to the outer wall of a cylinder body of the filtering rotary drum. The special-shaped protective sleeves are embedded in the filtering rotary drum holes to protect the cylinder body holes and the metal outer wall of the filtering rotary drum, the cylinder body of the filtering rotary drum can be effectively protected, abrasion and corrosion of the cylinder body are relieved, the outer wall of the cylinder body is covered with the shape and arrangement of the protection device to the maximum extent, the filtering holes and the wall of the rotary drum are protected, and the filtering hole protection sleeves are in the shape of a cone which is gradually reduced in the outward extending direction of the rotary drum hole, so that liquid thrown out of the filtering rotary drum can be effectively prevented from splashing to the outer wall of the rotary drum, and the abrasion of the rotary drum is further reduced. The protection device is simple in structure and remarkable in protection effect.

Description

technical field [0001] The invention relates to a protective device and a protective method for a centrifuge, in particular to a protective device and a protective method for a filter drum of a centrifuge. Background technique [0002] The centrifuge is a dehydration and recovery equipment for continuous processing of materials. It has a large processing capacity and low moisture in the product. It is widely used in mineral processing, chemical industry, environmental protection and other industries. As one of the core moving parts of the centrifuge, the drum is composed of three sections: the filter section, the cone section, and the big end drum, such as figure 1 shown. The filter drum is the cylinder for secondary dehydration of materials, and it is one of the most severely worn parts of the drum. The filtrate of the centrifuge is discharged from the radial hole through the screen gap on the inner wall of the drum in the filter section. Under the action of strong centri...
