Multi-stage cleaning device for insulator core rods

Abstract

The invention discloses a multi-stage cleaning device for insulator core rods, and belongs to the technical field of the manufacturing of electric power equipment. The device includes a casing, a conveyer, a first spraying mechanism and a second spraying mechanism; the casing is a semi-closed structure with openings on the two ends and an enclosed periphery; the internal of the casing is fixedly provided with the conveyer used for conveying insulator core rods; the upper part of the conveyer is successively provided with the first spraying mechanism and the second spraying mechanism in a conveying direction; the spraying liquid of the second spraying mechanism is a fresh cleaning solution; and the spraying liquid of the first spraying mechanism is the cleaning solution sprayed by the second spraying mechanism. Through the adoption of countercurrent secondary spray cleaning, good cleaning effects can be achieved, the cleaning solution entering follow-up drying equipment can be effectively reduced, so that the consumption of the cleaning solution and the thermal load of the follow-up drying equipment can be reduced, equipment investment and production costs can be lowered, and the surfaces of the insulator core rods can be smoother and cleaner after drying.

Description

technical field [0001] The invention belongs to the technical field of electric equipment manufacturing, and in particular relates to a multi-stage cleaning device for insulator mandrels. Background technique [0002] Insulators are widely used electrical components in power systems, mainly used to support and insulate wires. The mandrel of the insulator is an important component of the insulator, and its surface needs to be cleaned with a cleaning solution after manufacture. [0003] Patent No. CN 205845619U discloses "an automatic cleaning and drying system for insulator mandrels", including a frame, a screw drive roller, a liquid storage tank, a liquid spray pipe, a drive motor, a plunger pump and a dryer; The advanced cleaning system and ethanol cleaning liquid improve the efficiency of cleaning the mandrel surface, reduce the labor intensity of workers, and improve work efficiency; the two ends of the opening of the glass cover are respectively equipped with a rubber c...

AI Technical Summary

Problems solved by technology

[0004] However, the "automatic cleaning and drying system for insulator mandrels" disclosed in CN 205845619U has the following deficiencies in the actual production process: (1) fresh cleaning liquid is used to perform single-stage spray cleaning on the insulator mandrels to be cleaned, and the cleaning liquid The utilization rate is low, the amount of cleaning liquid consumed in the cleaning operation is large, and the cleaning effect of the single-stage spraying method is effective, which is not conducive to further improving the cleaning quality; (2) the surface of the insulator mandrel after being sprayed and cleaned by the cleaning liquid will remain The cleaning liquid directly enters the subsequent drying equipment, which will not only increase the consumption of the cleaning liquid, but also increase the heat load of the drying equipment, resulting in a significant increase in equipment investment and production consumption costs, thereby increasing the manufacturing cost of the insulator mandrel; ( 2) Part of the cleaning solution will remain on the surface of the insulator mandrel, and the stains dissolved in the cleaning solution will adhere to the insulator mandrel again after being dried by the drying equipment, reducing the cleaning effect of the insulator mandrel
