Efficient filtering centrifuge capable of conducting air blowing

Abstract

The invention discloses an efficient filtering centrifuge capable of conducting air blowing, and relates to a centrifuge. The filtering centrifuge comprises a centrifuge base (12), a centrifuge shell (10), a centrifuge cover (9), a rotary drum assembly (3), a power mechanism (11) and an air blowing system. The centrifuge cover (9) is provided with a feeding inlet (6), an air outlet (7), a viewport (8) and a scraper blade seat (4). A scraper blade rod (16) is arranged on the scraper blade seat, a mechanical transmission mechanism or a hydraulic transmission mechanism is arranged in the scraper blade seat, the scraper blade rod is a hollow pipe and is connected with a heater and an air compressor through hoses, and an umbrella-shaped baffle (17) is installed on the lower portion of the scraper blade rod (16). According to the efficient filtering centrifuge, a block-shaped filter cake is scraped off from a filtering medium through a scraper blade and then stirred to be loosened through a blade body, meanwhile, air is blown into a rotary drum through the air compressor, thus, surface liquid and capillary liquid are released, the moisture evaporation area is increased, and the drying process is accelerated. After air blowing, centrifugal filtering operation is repeated again, efficient filtering is achieved, and the product moisture content is decreased.

Description

Technical field [0001] The invention relates to a centrifuge, in particular to a blast high efficiency filter centrifuge. Background technique [0002] Filter centrifuge is the main equipment to realize solid-liquid separation, which is widely used in bioengineering, petrochemical, pharmaceutical, light industry, agriculture and forestry and other fields. Its working principle is to use the rotating drum to generate a centrifugal force field. Under the action of centrifugal force, the liquid phase in the solid-liquid mixture is discharged through the filter medium and the openings on the drum wall, and the solid particles are trapped on the filter medium. To achieve the purpose of solid-liquid separation. The centrifugal force of the mixture in the drum is thousands of times that of gravity, so the filtration process is strengthened, the filtration speed is fast, and the moisture content of the filter cake is low. Generally, the suspension with solid particles larger than 10 mi...

AI Technical Summary

Problems solved by technology

However, due to the design and operation of the filter centrifuge, many requirements such as the equipment footprint, the strength of the drum assembly, and the safety and stability of the operation must be considered, so the diameter of the drum and the rotational speed of the drum are limited, which makes it separate. It is difficult to further improve the capacity and separation effect, and cannot be applied to working conditions that require high material dryness
