Conical curved surface centrifugal oil throwing pan and ring-shaped air passage structure

Abstract

The invention discloses a conical arc-shaped centrifugal oil throwing pan and a ring-shaped air passage structure for more thorough purification treatment of oil fume, dust, paint residual mist and the like produced in households, restaurants and industries. Utilize the taper and arc surface of the centrifugal oil throwing plate to make the oil droplets hitting the plate fly away in a point shape and the gas can stick to the plate surface when flowing through the arc surface. The diameter of the plate is 1 / 3 larger than the diameter of the suction port to flow into the suction port Try to fill the entire surface of the disk with oil as much as possible, so that the oil that slides out of the disk should be as little as possible. The ring-shaped air passage is composed of an inner jacket, the front mouth of the inner jacket is fixedly connected to the edge of the disk and fixed with a rolling cage to facilitate the placement of a cylindrical filter sponge to further intercept and get rid of residual oil, and the rear mouth is fixedly connected to the fan impeller disk; the diameter of the suction port Less than 1 / 3 of the diameter of the conical arc surface centrifugal oil throwing pan, and the distance from the conical arc surface centrifugal oil throwing pan is 1 / 10 of the diameter of the conical arc surface centrifugal oil throwing pan. The large mouth of the outer cover is sealed and fixedly connected with the suction port of the fan housing, and the average interval between the inner and outer covers is slightly greater than that of the suction port, so that the airflow flowing into the suction port can be accelerated.

Description

technical field [0001] The present invention relates to the technical field of air purification, in particular to a method of using a cone-shaped arc-shaped centrifugal oil throwing pan and a ring-shaped airway structure to more thoroughly purify oil fume, dust, paint residue, and other pollution produced in households, restaurants, and industries. At the same time, waste oil that has not been polluted and deteriorated is collected to provide high-quality and cheap raw materials for aviation biofuel. Background technique [0002] At present, the more advanced method of household range hoods, range hoods for restaurants, and industrial pollution purification equipment is to use mesh disks made of thin steel wires and axial flow blades as a whole at the suction port, and use centrifugal force to throw a large amount of oil to the air. The effect of the surrounding collecting ring is more obvious, but 30% to 40% of the oil still enters the fan along the steel wire gap and the b...

Problems solved by technology

[0002] At present, the more advanced method of household range hoods, range hoods for restaurants, and industrial pollution purification equipment is to use mesh disks made of thin steel wires and axial flow blades as a whole at the suction port, and use centrifugal force to throw a large amount of oil to the air. The effect of the surrounding collecting ring is more obvious, but 30% to 40% of the oil enters the fan along the steel wire gap and the blade interval, and the production cost of the disk is high, the structural strength is low, it is easy to damage, and it is not easy to clean
