Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to a spraying device for an alkaline degreasing agent. Background Art

[0002] Alkaline degreasing agents are mainly used to remove oil stains from the surface of objects, especially before metal chemical treatment, electroplating and coating. The use of alkaline degreasing agents can effectively remove grease and mineral oil on the metal surface. The formula of alkaline degreasing agents usually contains surfactants such as isooctyl alcohol polyoxyethylene ether, coconut oil diethanolamide, cocamidopropyl betaine, as well as complexing agents such as sodium acetate and sodium sulfate. These ingredients work together to improve the degreasing effect.

[0003] When using alkaline degreasers, spraying is generally used, which can not only accurately cover the entire surface of the object, ensuring the cleanliness and quality of the object, but also improve work efficiency; since alkaline degreasers are generally composed of two components: component A is generally composed of alkaline substances, and component B is composed of a variety of surfactants. However, when in use, a spray device is usually used to connect to a container containing component A and component B in a certain proportion as a working fluid, and the alkaline degreaser is sprayed out under the action of the spray device. However, since the alkaline degreaser in the container may precipitate after being left standing for a long time, the degreasing effect of the alkaline degreaser sprayed by the spray device is poor.

[0038] The piston plate 3 divides the interior of the tank body 2 into two chambers, the mixing chamber 201 located above the piston plate 3 and the temporary storage chamber 202 located below the piston plate 3;

[0039] The tank body 2 is provided with a reciprocating assembly, the reciprocating assembly cooperates with the piston plate 3, and the fixed frame 1 is fixedly provided with a motor 4 for driving the reciprocating assembly. When the reciprocating assembly is running, the piston plate 3 will vertically reciprocate in the tank body 2 and can stir the alkaline degreasing agent liquid in the mixing chamber 201;

[0040] The tank body 2 and the piston plate 3 are provided with a spraying assembly, and the spraying assembly cooperates with the piston plate 3 which moves vertically back and forth, so as to perform a spraying operation.

[0041] In this solution, the reciprocating assembly and the piston plate 3 cooperate with each other through the drive of the motor 4. The piston plate 3 will move vertically back and forth under the action of the reciprocating assembly, and the vertically reciprocating piston plate 3 will cooperate with the spraying assembly, so that the alkaline degreaser enters the mixing chamber 201 and the temporary storage chamber 202 in the tank body 2 in turn, and is finally sprayed out from the temporary storage chamber 202.
