Description

A dismouting device that is used for membrane module to dismantle and install

Technical Field

The utility model relates to a dismouting device that is used for membrane module to dismantle and install belongs to membrane equipment technical field.

Background

In the water treatment technology, the nanofiltration membrane and the reverse osmosis membrane treatment method are widely applied, and due to the requirement of the working characteristics of membrane equipment, after the membrane equipment normally operates for a period of time, the membrane core is polluted by suspended matters, indissolvable substances and water treatment agents in water, so that the water yield of a membrane treatment system is reduced, and the normal operation of the membrane system is influenced. At the moment, the membrane core is firstly cleaned by adopting an online cleaning method, under the condition that the online cleaning effect cannot be achieved, the end plate which plays the role of fixing and protecting the membrane core is disassembled, then the membrane core is taken out from the membrane shell to be cleaned or replaced offline, the membrane core or a new replaced membrane core is installed back into the membrane shell after the cleaning is completed, and finally the end plate is installed. Because the gap between the end plate and the membrane shell is small, the edge of the end plate is provided with a sealing ring to keep the end plate and the membrane shell sealed, so that the end plate is not easy to take out from the membrane shell, and the time and the labor are wasted when the end plate is disassembled. Therefore, the existing membrane assembly disassembling tool adopts a support frame with a screw rod and a nut sleeve, the nut sleeve is provided with external threads which can be connected with an end plate, a handle is arranged on the screw rod and can drive the screw rod to rotate, when the nut sleeve is screwed into a water production connector of the end plate, the support frame is supported at the end part of a shell, the screw rod is screwed into an internal thread hole of the nut sleeve, the handle is rotated to drive the screw rod to rotate and gradually tighten the support frame, the support frame is fixed and positioned, then the handle is rotated to pull out the end plate connected with the nut sleeve from the shell, and the disassembly of the end plate is completed, but the tool can only be used for disassembling the end plate. When the end plate is installed in the membrane shell, the installation resistance is large due to the sealing ring, and the end plate is moved to a fixed position by using a manual knocking method. Nevertheless, the power of knocking is not of uniform size, and the end plate face atress is uneven, and crooked phenomenon can appear in the membrane shell because of the end plate, will be difficult for removing the fixed position to in the membrane shell after the end plate is crooked, and crooked end plate can increase the degree of difficulty of demolising next time, will fix unreliable to the membrane core, and influence the use, reduced production efficiency, consequently current membrane module extracting tool only can pull down the end plate, and can not install the end plate in the membrane shell, therefore adaptability is poor.
