Introduction to a water filter with convenient filter cartridge replacement

　　Filters are indispensable devices in conveying medium pipelines, usually installed at the inlet of pressure reducing valves, pressure reducing valves, and constant water level valves of square filters. An ideal filter consists of a cylinder, a stainless steel filter screen, a drainage part, a transmission device, and an electrical control part. The water to be treated passes through the filter cartridge of the filter screen, and its impurities are blocked. When cleaning is needed, simply remove the detachable filter cartridge, process it, and reinstall it. It is very convenient to use and maintain. However, the existing Water filter It is very inconvenient to replace the filter element, the replacement steps are cumbersome, and the filter element is easily damaged during the replacement process, which cannot meet the needs of use.

　　To solve the existing Water filter In order to solve the problems of inconvenient filter element replacement, cumbersome replacement steps, and easy damage of the filter element during replacement, technical personnel provide a water filter with convenient filter element replacement. To achieve the above purpose, it adopts the following technical scheme: A water filter, including a filter box, a support column fixedly set at the bottom of the filter box inner cavity, a support plate fixedly set at the top of the support column, a limit ring set at the top of the support plate, a filter element fixedly installed in the limit ring, the filter element passing through the limit ring, and a first flange set at the top of the filter element and communicating with the filter hopper. The filter hopper is located at the top of the filter element, a filter screen is provided inside the filter hopper, sliders are fixedly installed on both sides of the filter hopper, and limit grooves are provided on both sides of the filter box inner cavity, the sliders being located inside and slidably connected with the limit grooves; an outlet pipe is connected to the right side of the filter box, and a control valve is provided at the top of the outlet pipe.

　　Among them, the top of the filter box is rotatably connected to the sealing cover through a hinge; a water guide pipe is provided inside the sealing cover, and the water guide pipe passes through the sealing cover; a second flange is provided at the top of the water guide pipe; the water guide pipe is connected to the inlet pipe through the second flange; and a handle is fixedly installed on the upper right side of the sealing cover. Handles are fixedly installed on both sides of the filter bucket inner cavity, and the handles are located above the filter screen. Alignment rods uniformly distributed are fixedly set at the top of the support plate, and alignment grooves uniformly distributed are provided in the limit ring, the alignment rods being located in the alignment grooves. A limit through-slot is provided inside the support plate, the limit through-slot being located between the alignment rods, and the filter element passing through the limit through-slot extends to the bottom of the support plate.

　　Compared with the existing technology, the water filter has the following beneficial effects: 1. By optimizing the structure and setting the filter bucket to fix the filter screen while connecting the filter element, the filter bucket and filter element can be easily removed through the handle, so as to conveniently replace the filter element; at the same time, the filter screen is used for primary filtration of liquid, and the outlet pipe is used to discharge the filtered liquid, which solves the existing Water filter The problems of inconvenient filter element replacement, cumbersome replacement steps, and easy damage of the filter element during replacement are solved. 2. By setting the sealing cover, the filter box can be easily opened and closed. By setting the inlet pipe and the second flange, the external water can be easily introduced into the filter hopper. By setting the limit through-slot, the filter element can be easily prevented from shifting, making the water filter more convenient to use.
