Time difference type centrifugal solid liquid separator

Abstract

The invention provides a time difference type centrifugal solid liquid separator, which comprises at least three radial blade discs in coaxial arrangement, wherein each blade disc comprises a round installing disc, blades fixed at the outer edge of the installing disc and a fixing ring arranged around the outer edges of the blades; each blade is arranged along the radial direction of the corresponding installing disc; all blades of each installing disc are in equal-interval uniform distribution along the circumferential direction of the installing disc; the blades on the adjacent blade discs are in sequential staggered arrangement; a flow guide groove is formed in the surface of one side of each blade; each flow guide groove is formed along the radial direction of the corresponding blade and penetrates through two ends of the blade. The two ends of the blades are fixedly connected, so that high stability is realized; the production and the processing are convenient; the production efficiency is high; the production cost is low; three or more layers of blades in step-shaped layer-by-layer staggered arrangement are used, so that the covering area is large; the flow guide grooves areformed in the blade surfaces, oil drops cannot easily fall off from the side surfaces of the blades, and the oil smoke separation efficiency and effect are improved.

Description

Technical field [0001] The invention relates to the field of solid-liquid separators, in particular to a time difference centrifugal solid-liquid separator with higher efficiency. Background technique [0002] Solid-liquid separation is a very widely used technology in modern society, and it has many applications in industrial production, experimental treatment, environmental protection, and household life. One of the typical applications is the range hood, which is a kitchen appliance that purifies the kitchen environment. It is installed in the kitchen, can quickly remove the waste from the stove and the harmful fumes generated during the cooking process, and discharge it to the outdoors, and has the safety protection effect of anti-virus and explosion-proof. However, with the improvement of people’s living standards, the awareness of physical health and environmental protection has increased. Exhaust fans and range hoods that were previously used to only exhaust oil fume in t...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a time-difference centrifugal solid-liquid separator, which is used to solve the gaps in the existing oil fume separator due to the single-layer and double-layer design, and the smooth blade surface will throw off It also solves the problem of poor purification effect due to oil removal; it also solves the problem of easy falling off of the existing oil fume separator using single-end welding blades, or the troublesome installation, low efficiency, and high cost of using press-fit fixed blades
