Dehumidifier for electrical control cabinet

Abstract

A dehumidifier for an electrical control cabinet comprises a cabinet body, heating pipes, a drawing box, an air supply device, a pressing plate and an attaching plate. The interior of the cabinet bodyis divided into an installation bin for installing electrical elements and a storage bin through a partition plate, and a first through hole is formed in the partition plate. The installation bin isarranged on an exhaust device at the top of the cabinet body; a U-shaped plate is arranged in the storage bin; the inner end face of the U-shaped plate is provided with a first sliding groove in the circumferential direction of the U-shaped plate. The drawing box is connected with the attaching plate, and a sliding plate is arranged on the peripheral face of the drawing box. The sliding plate is connected with the attaching plate; a second through hole and multiple layers of filter screens are arranged on the bottom surface of the drawing box, and the pressing plate is arranged in the drawingbox; a plurality of groups of vent holes are uniformly formed in the pressing plate; a water absorption bin used for containing water absorption materials is formed between the pressing plate and theinner wall of the drawing box. The sliding plate is inserted into the first sliding groove in a matched mode. The storage bin is provided with a plurality of groups of air inlet holes in the cabinet body; the air supply device and the multiple sets of heating pipes are installed in the storage bin side by side. According to the electrical control cabinet, air entering the electrical control cabinet can be effectively dehumidified and dried.

Description

technical field [0001] The invention relates to the technical field of electric control cabinets, in particular to a dehumidifier for electric control cabinets. Background technique [0002] With the development of the times and the progress of industry, the processing equipment in the factory is becoming more and more high-end, and there are more and more control switches in it. In order to ensure that the control switches and other components can be better protected, it is necessary to use electrical control The use of electrical control cabinets and electrical control cabinets not only improves the protection effect of electrical control switches, but also improves the safety of operators; however, the use environment of electrical control cabinets is often relatively poor, and most electrical control cabinets are kept in humid or dusty places for a long time. In the environment, humid air or dust-carrying air enters the electrical control cabinet, which will affect the o...

[0002] With the development of the times and the progress of industry, the processing equipment in the factory is becoming more and more high-end, and there are more and more control switches in it. In order to ensure that the control switches and other components can be better protected, it is necessary to use electrical control The use of electrical control cabinets and electrical control cabinets not only improves the protection effect of electrical control switches, but also improves the safety of operators; however, the use environment of electrical control cabinets is often relatively poor, and most electrical control cabinets are kept in humid or dusty places for a long time. In the environment, humid air or dust-carrying air enters the electrical control cabinet, which will affect the operation of the electrical components inside the electrical control cabinet, resulting in equipment failure and requiring shutdown for maintenance; in addition, the internal wiring of the electrical control cabinet is cluttered, which greatly increases Difficulty in maintaining electrical control cabinets; for this reason, this application proposes a dehumidifier for electrical control cabinets
