Description

A membrane shell end plate remover

technical field

The invention relates to the field of special tools for water treatment equipment, in particular to a special tool for disassembling membrane shell end plates.

Background technique

Reverse osmosis equipment is widely used in the field of water treatment, and the reverse osmosis membrane shell is an indispensable component of reverse osmosis equipment. When installing and replacing the reverse osmosis membrane module, it is necessary to remove the membrane shell end plate. The long-term use of the reverse osmosis equipment will lead to the adhesion of the membrane shell end plate and the membrane shell, and it is very difficult to disassemble. The common membrane shell end plate disassembly tool operated by a wrench is time-consuming and laborious, and it is impossible to apply force smoothly, which is easy to cause impact on the membrane shell end plate. , it cannot even be removed, and what is more, the rotation of the screw will cause irreversible damage to the membrane casing end plate during disassembly; due to the interface problem of different membrane casing end plates, conventional membrane casing end plate disassembly tools cannot be used universally.

The invention provides a special tool, which can solve the problem of difficult disassembly of the membrane shell end plates, and at the same time, a set of tools can be used for disassembling the membrane shell end plates of various specifications.

SUMMARY OF THE INVENTION

The main technical problem solved by the present invention is: to provide a membrane casing end plate disassembler, which uses a gear and a toothed disc device, can amplify the torque, and can remove the membrane casing end plate through the lead screw by applying a small force. plate is pulled out. A set of tools can be used to disassemble a variety of membrane casing end plates of different specifications; the membrane casing end plates that are too tightly assembled or difficult to disassemble can also be easily and smoothly removed.

In order to solve the above technical problems, the technical solution adopted in the present invention is to provide a membrane casing end plate disassembler, the disassembler includes: a toothed plate mounting seat, a bevel gear, a toothed plate, a lead screw, a locking device, a lock Tighten the joint and the handle.

The invention provides a disassembler for the end plate of the membrane casing. The disassembler is characterized in that: three bevel gears are distributed on the mounting seat of the toothed plate, and the bevel gear is provided with a semicircular groove. The screw is fixed on the mounting seat of the toothed plate; the top of the bevel gear is provided with a crank handle, the bevel gear meshes with the toothed plate, and any one of the bevel gears is rotated by the crank handle to drive the toothed plate to rotate. The torque of the crank is amplified by the transmission ratio of the bevel gear and the toothed plate; the center of the toothed plate is provided with a screw nut, and the screw nut and the lead screw form a lead screw pair. There is a guide groove at the bottom of the lead screw, and the guide key on the tooth plate mounting seat is embedded in the guide groove at the bottom of the lead screw. When the tooth plate and the screw nut rotate, the lead screw can only move linearly and will not rotate with the tooth plate and the lead nut; Use the crank to turn the bevel gear, the bevel gear and the chainring to amplify the torque, while the nut and the lead screw convert the rotary motion of the chainring into the linear motion of the lead screw, so that the diaphragm casing end plate can be moved from the end plate with less force. Fast and smooth pulling out of the membrane housing.

The membrane shell end plate disassembler is equipped with a quick locking device. The end of the lead screw is connected to the locking joint through the locking device, and the locking joint is connected with the membrane shell end plate through the thread. When disassembling the membrane shell end plate, screw the locking joint first. To the threaded hole in the center of the membrane casing end plate, the disassembler and the locking joint are quickly locked by the locking device, so as to transmit the pulling force of the lead screw to the membrane casing end plate; Locking joints can be used for the dismantling of membrane casing end plates of various specifications. Only suitable locking joints need to be selected for different specifications of membrane casing end plates.
