Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure water filtering equipment, in particular to a high-pressure water filter. Background Art

[0002] High-pressure drinking water refers to ordinary drinking water that has been pressurized to a certain pressure by a pressurizing device. In high-rise buildings, due to their height, the ordinary municipal water supply pressure cannot meet the water needs of users on the upper floors. Therefore, a high-pressure water supply system is needed to pressurize the water and transport it to the upper floors. In some industrial production processes, high-pressure drinking water is needed for cleaning, cooling, dilution and other operations. Filtration is essential for our daily drinking and production use.

[0003] For existing high-pressure water filters, technicians connect the water inlet and outlet to the corresponding positions. When the filter element needs to be replaced after long-term use, other tools are needed to disassemble the filter to replace the filter element inside.

[0004] Existing high-pressure water filters of this type require additional tools, which means that in an operating environment where space may already be limited, hands must be freed up to pick up and operate the tools. Replacing the filter element with the help of tools usually requires certain operating skills and experience. To this end, we propose a high-pressure water filter. Utility Model Content

[0006] To achieve the above object, the present invention provides the following technical solution: a high-pressure water filter, comprising a housing, a filter cover provided at the upper end of the housing, a filter element provided inside the housing, the housing being a stainless steel housing, and further comprising a locking mechanism;

[0007] Locking mechanism: It includes a limit block, an insertion strip and a fixing groove. The bottom wall of the filter cover is provided with evenly distributed limit blocks, and the upper ends of the limit blocks are slidably connected with the insertion strips. The outside of the filter cover is provided with avoidance holes corresponding to the limit blocks. The upper end of the inner wall of the shell is provided with a fixing groove, and the fixing grooves are installed in conjunction with the insertion strips. The opening operation of the cover and the replacement of the filter element can be completed in a very short time, which greatly improves work efficiency, avoids the inconvenience caused by carrying and using tools, and enhances the convenience of using the filter.

[0008] Furthermore, the locking mechanism also includes a connecting rod, a turntable, a rotating column and a dial wheel. The top wall of the filter cover is rotatably connected to the rotating column, and the bottom end of the rotating column is provided with a turntable. The bottom end of the turntable and the top end of the insert close to the center of the shell are rotatably connected to the connecting rod through a pin shaft. The top end of the rotating column is fixedly connected to the dial wheel, and the upper end of the dial wheel is threadedly connected to a locking bolt, so that the filter cover can be installed conveniently and quickly.

[0009] Furthermore, slots are respectively provided on the inner wall of the shell, and plug-in blocks are respectively provided on the outer top of the filter element, and the plug-in blocks are respectively plugged into adjacent slots to facilitate the replacement of the filter element.

[0010] Furthermore, a sealing strip is provided at the connection between the shell and the filter cover to ensure good sealing of the filter.

[0011] Furthermore, a water outlet is provided at the left end of the exterior of the shell, a water inlet is provided at the right end of the exterior of the shell, and connection holes are respectively provided at the ends of the water inlet and the water outlet away from the center of the shell, so as to facilitate quick connection with the external water pipe.

[0012] Furthermore, a sewage pipe is provided at the external bottom end of the shell, and a regulating valve is provided at the external upper end of the sewage pipe to facilitate cleaning of the inside of the filter.

[0013] Furthermore, a bracket is provided at the bottom end of the shell, and ventilation holes are respectively opened on the outside of the bracket to prevent decay caused by long-term immersion.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the high-pressure water filter has the following advantages:

[0015] The rotation of the turntable drives the insert to move centripetally away from the fixed groove, so that the filter cover can be quickly opened and the filter element can be pulled out for replacement. There is no need to use tools to open the filter cover for quick replacement of the filter element. The cover opening operation can be completed in a very short time, and the sealing performance of the filter will not be affected due to the loose installation of the cover.
