Air pressure umbrella-shaped framework retractable liquid injection equipment

Abstract

The invention discloses air pressure umbrella-shaped framework retractable liquid injection equipment. The air pressure umbrella-shaped framework retractable liquid injection equipment comprises a hollow main pipe, a hollow branch pipe, a sliding sleeve, an air compressor and a nozzle. The sliding sleeve sleeves the hollow main pipe in a sliding manner, and the air compressor is communicated with the main channel; the hollow branch pipe comprises a first hollow branch pipe and a second hollow branch pipe which are hinged to each other and internally communicated, one end of the first hollow branch pipe is hinged to the sliding sleeve, and one end of the second hollow branch pipe is hinged to the hollow main pipe; the nozzles are assembled on the first hollow branch pipe and the second hollow branch pipe respectively, the nozzles on the first hollow branch pipe are communicated with the interior of the first hollow branch pipe, and the interior of the second hollow branch pipe is communicated with the nozzles on the second hollow branch pipe and the main channel respectively; the sliding sleeve correspondingly drives the first hollow branch pipe and the second hollow branch pipe to be unfolded or folded in the sliding process, and liquid in the main channel flows to the hollow branch pipes under the action of the air compressor and is sprayed out of the nozzles. Therefore, liquid (such as an anti-foaming agent) can be uniformly injected.

Description

technical field [0001] The invention relates to the production field of lubricating oil, in particular to a pneumatic umbrella-shaped skeleton retractable liquid injection device for injecting liquid such as antifoaming agent into lubricating oil. Background technique [0002] Lubricating oil is a non-volatile oily lubricant. According to its source, it is divided into three categories: animal oil, vegetable oil, petroleum lubricating oil and synthetic lubricating oil. The amount of petroleum lubricating oil accounts for more than 97% of the total amount. Therefore, lubricating oil often refers to petroleum lubricating oil. Oil is mainly used to reduce the friction between the surfaces of moving parts, and at the same time, it has the functions of cooling, sealing, anti-corrosion, rust prevention, insulation, power transmission, cleaning impurities and so on for machinery and equipment. [0003] Among them, in the production process of lubricating oil, according to the needs...

AI Technical Summary

Problems solved by technology

Although the blending kettle can make the lubricating oil and the antifoaming agent uniformly mixed to a certain extent, since the antifoaming agent is artificially added to the surface of the lubricating oil in the blending kettle, the antifoaming agent on the surface of the lubricating oil is It is difficult to mix evenly into each layer of lubricating oil during stirring, thus affecting the quality of lubricating oil
