Problems solved by technology

However, after the separator is added, the viscous sand and gravel will accumulate near the separator to form a solid slag pile. After a long time, it will wear the blade after reaching a certain thickness. After the blade is worn, the thickness of the solid slag pile will increase. After 3 months, it needs to be cleaned once, which increases the operating cost and maintenance cost of the equipment

Abstract

The invention relates to a horizontal spiral discharge settling centrifuge which comprises a revolving drum and a screw; spiral blades are arranged on the screw; a housing covers the revolving drum; a feed opening communicated with the inner cavity of the screw is formed in one end of the housing; a liquid outlet is formed in one end, close to one end of the feed opening, of the lower end of the housing; a bleed hole is formed in the other end; at least 20 grooves are formed in the inner wall of the revolving drum in the circumferential direction. The grooves are formed in the inner wall of the revolving drum to prevent a liquid phase from forming a water film and a solid phase from accumulation, the abrasion of the blade is avoided, and the normal work of the blade is not influenced even if part of the solid phase is accumulated in the grooves.

Description

technical field [0001] The invention relates to a horizontal spiral unloading sedimentation centrifuge. Background technique [0002] The horizontal screw unloading decanter centrifuge is referred to as the horizontal screw machine, which can be used in the production process of industrial, agricultural and by-products, and is also the key equipment of the sludge dewatering system in the environmental treatment project. Can separate solid-liquid particle equivalent diameter ≥ 3μm, weight concentration ratio ≤ 10% or volume concentration ratio ≤ 70%, liquid-solid density difference ≥ 0.05g / cm 3 various suspensions. [0003] The horizontal screw discharge decanter centrifuge mainly includes a high-speed drum and a screw whose rotation speed is the same as the rotation speed and slightly higher or lower than the drum. After the drum, the high-speed rotating drum generates a strong centrifugal force to settle the solid phase particles with a higher density than the liquid pha...
