Filter allowing rapid replacement

Abstract

The invention discloses a filter allowing rapid replacement. The filter includes: a container equipped with a filter core, a transfer connection port, and a cover body, wherein the filter core, the container and the connection port are welded together to form an integrated structure. The connection port is used for connecting the container equipped with a filter core to the cover body. The cover body is used for forming a loop with exterior. Two cylindrical ports, including an external connection port and a first inner connection port, are arranged on the transfer connection port. A first pipe connection port, a second pipe connection port and an exhaust port are disposed on the cover body. The transfer connection port can be clamped in or detached from the cover body through simple operation. The filter can be installed and replaced quickly with simple operation, thereby saving time and labor. The cover body having the tube ports can be repeatedly used so as to avoid reduction on sealing property of the tube ports due to frequent detachment. During the replacement of the filter core, potential danger of chemical liquids on operators and surrounding equipment is avoided.

Description

technical field [0001] The invention relates to a filter, in particular to a rapidly replaceable filter. Background technique [0002] Cartridge filter is a multi-functional filter widely used in chemical, pharmaceutical, microelectronics and other industries. Most of the existing filters adopt an integrally formed structure that cannot be disassembled, including a high-pressure resistant shell and filter element. Generally, pipe joints connected with the liquid input pipe and the liquid output pipe are provided at the upper and lower ends of the shell. Sometimes it is necessary to Add a pipe joint for exhaust. When replacing the filter, it is necessary to unplug the filter as a whole from the liquid input pipe, liquid output pipe and exhaust pipe joint, and then reconnect a new integral filter. During the process of unplugging the input and output pipes, the chemical liquid remaining in the bottom of the filter and in the pipeline may splash the operator, posing a safety ...

AI Technical Summary

Problems solved by technology

During the process of unplugging the input and output pipes, the chemical liquid remaining in the bottom of the filter and in the pipeline may splash the operator, posing a safety hazard, and nearby equipment will also be affected by potential damage, and it must be removed and restarted many times. The installation is easy to damage the interface, and the joint after reinstallation is easy to cause leakage

Therefore, this traditional filter has many shortcomings during use. It is necessary to solve the problems of the traditional filter in the process of replacing the filter element and make the filter disassembly process more convenient and safe.
