Mechanical part spraying device capable of preventing precipitation

Abstract

The invention relates to the technical field of mechanical parts, and discloses a mechanical part spraying device capable of preventing precipitation. The mechanical part spraying device comprises a liquid storage machine body, an air pipe is fixedly connected to the inner wall of the liquid storage machine body, an air hole is formed in the bottom of the air pipe, a through pipe fixedly connected with the air pipe is arranged on the inner wall of the liquid storage machine body, and a piezoresistor is fixedly connected to the inner wall of the liquid storage machine body. According to the mechanical part spraying device capable of preventing precipitation, the spraying device stops working, a submersible pump stops working, spraying liquid stops flowing in a water conveying pipeline, a clamping block drives a dielectric plate downwards under the action of a first spring, the relative area between a positive plate and a negative plate is changed to generate current, the current reaches the minimum resistance value of the piezoresistor, so that an electromagnetic valve is opened, nitrogen enters the air pipe through the through pipe and then enters the liquid storage machine body through the air hole formed in the air pipe, fine particles precipitated by the spraying liquid are mixed according to the principle of a fluidized bed, and therefore the effect of preventing the spraying liquid from precipitating is achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical parts, in particular to a mechanical part spraying device for preventing precipitation. Background technique [0002] Parts refer to the inseparable individual parts of the machine, which are the basic components of the machine. In the manufacturing process of the parts, the spraying of the parts is a relatively important part of the processing of the parts, which not only affects the appearance of the parts but also determines the The service life of parts is generally sprayed with spray gun on the surface of parts. [0003] Parts spraying tools currently on the market have certain deficiencies. Usually, the spraying liquid contains certain tiny particles. When spraying tools in the assembly line, after spraying the mechanical parts, the cavity storing the spraying liquid is at rest before the arrival of the next part. state, it is easy to cause the spraying liquid to settle, and it is diffic...
