An intelligent feeding device for a variety of coating raw slurry for casting

Abstract

The invention provides an intelligent loading device for a plurality of raw coating pastes for casting. The intelligent loading device comprises a support, a loading hopper, a pneumatic diaphragm pump, a high-liquid-level tuning fork switch, a medium-liquid-level tuning fork switch, a low-liquid-level tuning fork switch, a displacement sensor, a pneumatic ball valve, a pipeline and a fixed-moment die spring, wherein the loading hopper is installed on the upper end surface of the support; the pneumatic diaphragm pump is installed at a middle position of the lower end surface of the support; the pneumatic ball valve is assembled on the pneumatic diaphragm pump; the pipeline is installed on the upper end surface of the pneumatic diaphragm pump; the high-liquid-level tuning fork switch is installed at the upper end of the loading hopper; the medium-liquid-level tuning fork switch is assembled at a middle position of the loading hopper; the low-liquid-level tuning fork switch is installed at a lower position of the loading hopper; the displacement sensor is assembled at the junction of the loading hopper and the support; and the fixed-moment die spring is installed at the junction of the displacement sensor and the loading hopper. The intelligent loading device provided by the invention is reasonable in structure, high in control accuracy and reliability, less in influence of environment and human factors, and wide in application range.

Description

technical field [0001] The invention relates to an intelligent feeding device for various coating raw pastes for casting, which belongs to the field of casting machinery and equipment. Background technique [0002] The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it like this: "Painting is a kind of material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, certain strength, and continuous coating. Solid film.The film formed in this way is commonly called coating film, also known as paint film or coating. [0003] The paint indust...

Problems solved by technology

[0005] In the prior art, with the vigorous development of the construction industry, the use of paint has increased greatly. The mixing of paint requires the addition of a large amount of paint stock. However, these paint stock is often heavy. Traditional paint stock The feeding method requires a lot of manual intervention (manual mixing, filling care, pumping operation, stop intervention, etc.), which greatly increases the labor intensity of the operators, and cannot realize the automatic identification of the original pulp, and the feeding efficiency is low, which greatly increases The project time affects the progress of the project, so there is an urgent need for an intelligent feeding device for multiple coatings for casting to solve the above problems
