Description

Filter tank type positioning structure and operation method thereof

The invention relates to a positioning structure; in particular to an innovative design of a filter can cassette positioning structure and a method of operating the same.

The fluid (especially water) separation device mainly uses the fluid to pass through the filter canister provided therein, and filters out the impurities (miscellaneous) which are toxic, unnecessary or have adverse effects on the subsequent processes, so as to facilitate Subsequent use. For example, in the case of a conventional filter can with a joint, it is often installed in a relatively small and inconspicuous space due to the use of a limited space in the working environment. After the filter element in the filter is used for a certain period of time, it will definitely absorb a lot of impurities or toxins, and gradually reduce its filtering function, even worsening the water pollution to be worse than before filtering. At this time, the filter element must be replaced immediately. The traditional filter replaces the filter core, usually using a suitable tool to loosen the filter housing first. However, in a small space, it is not convenient to use the tool to rotate the joint during the disassembly process. There must also be extra space to allow the canister to move vertically during disassembly and assembly. However, in many installation environments, it is not easy to reserve such a workspace.

Furthermore, some industrial filters must meet the requirements of safety regulations (such as fluid pressure), so metal rigid pipes are used as the conduit for conveying fluids. However, it is more inconvenient for the operators to use the rigid pipes to configure the pipelines. Disassemble the traditional filter cans.

In addition, the traditional filter canister is the most criticized by the operator, that is, during the disassembly process, even if the pipeline has been relieved, there is still a problem of leakage, and if the filter is used to filter chemicals used in special industries, Whether it is from an environmental point of view or the operator's personal safety considerations, of course, such chemicals are not expected to leak out of the pipeline.

In summary, the conventional structure has found that the following problems and disadvantages still exist in the practical application experience: First, the installation environment is not easy to reserve space for use when disassembling the filter can; therefore, when disassembling or installing the filter element There is not enough space for the tool (wrench) to make a swing motion, which often seems to be inconvenient. In addition, if the water inlet and the water outlet are respectively located above and below the filter, and the connected pipelines are all hard tubes, Replacing the filter element before use, sometimes even having to close the water source to disassemble the water pipe, makes the work of replacing the filter material complicated and time consuming. What's more, if the filter tank is used to filter toxic or dangerous chemicals, it is not allowed to leak fluid when replacing the filter tank. If it is not redesigned and changed the installation method of the conventional filter can positioning structure, it may have a bad influence on its market acceptance, and indirectly reduce the profit of the filter industry.

Therefore, in view of the problems existing in the above-mentioned conventional technologies, how to develop an innovative structure that can be more ideal and practical, and the relevant industry should further consider the goals and directions of breakthrough.

In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the inventor has finally obtained the practical invention.
