Abstract

The invention provides a rotary exhaust fume collecting hood for oil fume purification. The rotary exhaust fume collecting hood can be quickly opened and closed while ensuring oil fume collection, so that the automation of equipment is improved, and the working efficiency is improved. The rotary exhaust fume collecting hood for oil fume purification is arranged at the upper part area of an oil quenching tank and is characterized by comprising a mounting base, an inner shield and an outer shield, wherein the mounting base is fixedly arranged on the upper ring surface of the oil quenching tank; the inner shield comprises a first annular top baffle at the top and a first surrounding plate with a semi-arc-shaped periphery; the outer shield comprises a second annular top baffle at the top and a second surrounding plate with a semi-arc-shaped periphery; a through hole is formed in the center of the mounting base, and a first guide circular track groove and a second guide circular track groove are formed in the annular upper surface of the mounting base; the bottom of the first surrounding plate is embedded in the first guide circular track groove; the bottom of the second surrounding plate is embedded in the second guiding circular rail groove; the diameter of the inner shield is smaller than that of the outer shield in an overlook state; and the first surrounding plate and the second surrounding plate are combined to form a circular shield in a closed state.

Description

technical field [0001] The invention relates to the technical field of smoke collecting structures, in particular to a rotating smoke collecting hood for oil fume purification. Background technique [0002] According to the heat treatment process of large mechanical parts, the quenching oil tank produces a large amount of oil fume exhaust gas, which is collected through the collection cover, and sent to the atomization box activated carbon box for treatment. treatment, and finally exhausted by a centrifugal fan and discharged at a high altitude through the exhaust tube. Among them, the oil fume collection cover is an important key component. It is necessary to meet the collection of oil fume and exhaust gas when the quenching tank is opened without leakage; the oil fume and exhaust gas will burn when the quenching tank is opened without open flames. During the combustion process, the volume of the oil fume and exhaust gas will expand. After the exhaust gas is discharged, t...
