Description

Special tool for dismantling boiler filter element

Technical Field

The application belongs to the field of bearing tools, and particularly relates to a special tool for dismantling a boiler filter element.

Background

The raw water of the boiler is initially filtered by the gravity filter tank and then is produced by the reverse osmosis device, and the filter element of the precision filter in front of the reverse osmosis device is frequently overpressurized due to the large microorganism content in the water, so that six filter elements are required to be replaced twice a week. Because the filter element is provided with the sealing rings up and down, the sealing rings are made as large as possible to ensure tightness, so that lifting is difficult during replacement, and the monorail crane is required to be used for auxiliary lifting.

In the past, when changing the filter core, need to pull out the filter core through the hand grip on the filter core with monorail crane, suspender, the hand grip is because too big intensity of pulling force is not enough, easily takes place the fracture, if the fracture then need use screwdriver sled excircle sealing part, easily causes sealed face damage and reveal. Therefore, when the filter element is replaced, the handle is pried off and is plugged into the filter element by the bolt, and the single-rail crane is used for pulling out, the bolt is inclined and stressed to be easy to slip, and the hanging strip and the bolt are ejected out to hurt people. When the bolts are used, the handle of the filter element must be pried off, such as the upper cover of the filter element is pulled off, and no stress point exists when the filter element is replaced. The filter element is required to be damaged and then put forward, the time and the labor are wasted in the process of adding, and if the water treatment amount is large, the rush repair is easy to cause.
