Double-liquid-well-type cleaning machine with air floatation separation device

Abstract

The invention discloses a double-liquid-well-type cleaning machine with an air floatation separation device. The double-liquid-well-type cleaning machine comprises an alkali water channel, an alkali water spraying pump, a clean water spraying pump, a clean water channel, a switching valve, an air compressor, an oil skimmer, a spraying chamber and a bubble generating pipe, wherein the spraying chamber is located above the alkali water channel and the clean water channel, the alkali water spraying pump is arranged on the side edge of the alkali water channel, the clean water spraying pump is arranged on the side edge of the clean water channel, the switching valve controls sprayed alkali water to flow back to the alkali water channel and controls sprayed clean water to flow back to the clean water channel, and the oil skimmer is located above the alkali water channel. According to the double-liquid-well-type cleaning machine with the air floatation separation device, the bubble generating pipe is arranged inside the alkali water channel, a plurality of small holes are drilled in the bubble generating pipe, the bubble generating pipe is connected with the air compressor through a pipeline, air passes through the small holes in the bubble generating pipe to form tiny bubbles which enter the alkali water in the alkali water channel, the oil-water separating rate of alkali water with oil is improved, the oil-water separating time is shortened, and the cleaning effect and running efficiency of the oil cleaning machine are remarkably improved.

Description

technical field [0001] The invention belongs to heat treatment equipment, and specifically refers to the structural technology of a double liquid well type oil cleaning machine for heat treatment equipment. Background technique [0002] The existing double-fluid well type oil cleaning machine first uses alkaline water to spray the oily workpiece when cleaning the workpiece, and the oily alkaline water after spraying is returned to the alkaline water tank, and the workpiece is sprayed with clean water after the alkaline water spray cleaning , the clean water after spraying returns to the clean water tank, and the oily alkaline water is separated from the alkaline water after standing, and then taken out of the washing machine through the oil skimmer set on the alkaline water tank. Due to the low separation rate of oil and alkaline water after standing, the separation time is longer, resulting in the oil content of alkaline water increasing with the increase of the number of u...

AI Technical Summary

Problems solved by technology

Due to the low separation rate of oil and alkaline water after standing, the separation time is longer, resulting in the oil content of alkaline water increasing with the increase of the number of uses, and the increased oil content reduces the cleaning effect of alkaline water on workpieces, and The remaining oil on the workpiece enters the clear water tank, which further reduces the washing effect. At the same time, because the oily alkaline water needs to stand for a long time, the operating efficiency of the equipment is reduced.
