Technical Field

The utility model relates to the technical field of water treatment equipment, in particular to a disassembling tool for an end cover of a water treatment RO (reverse osmosis) membrane shell.

Background

At present, RO (Reverse osmosis) equipment is mostly adopted in the water treatment industry for filtration, and Reverse osmosis water treatment equipment is an important component for manufacturing high-purity water equipment and is used for separating pure water from inorganic salts and organic impurities dissolved in the water by utilizing pressure as a driving force. The RO membrane of the equipment is usually installed in the RO membrane shell, and the outside is blocked by the RO membrane shell end cover, so when the RO membrane needs to be replaced, the RO membrane shell end cover needs to be detached firstly.

However, the end caps of the RO membrane shell are all embedded in the RO membrane shell, and a certain distance exists between the outer surface of the end cap of the RO membrane shell and the outer surface of the RO membrane shell, which is very inconvenient to operate. The traditional mode of dismantling is generally in the screw hole that screws in RO membrane shell end cover with the bolt of appropriate length or the stock instrument that is equipped with the external screw thread, and this extracting tool screw thread exposes in the outside, not only wastes time and energy, work efficiency is low, hurts the hand easily with the hand gripping in-process moreover.

Therefore, how to solve the problem that the existing dismounting mode is generally to screw a bolt with a proper length or a long rod tool with external threads into a threaded hole of the RO membrane shell end cover, and the thread of the dismounting tool is exposed outside, so that the dismounting tool not only wastes time and energy and has low working efficiency, but also easily hurts hands in the hand gripping process, and becomes an important technical problem to be solved by professional technicians in the field.
