Description

Technical Field

[0001] The invention relates to the field of filters, and in particular to a locking device for a flip-type filter upper cover and a locking method thereof. Background Art

[0002] Filters are usually used in water treatment systems or sewage treatment systems, and include a filtration unit and a dosing tank unit. Among them, filters are usually devices used to remove suspended matter, impurities and solid particles in water. These filters can adopt different working principles and filter media, such as sand filters, filter screens, filter bags, etc., to meet different water quality treatment requirements.

[0003] For example, the patent document with patent number 202321481069.1 discloses a low-residue bag filter structure, including a filter housing, a guide assembly and a filter assembly; the filter housing includes a main barrel, on which a liquid inlet and a liquid outlet are provided; the guide assembly includes a filter upper seat and a filter lower seat arranged in the main barrel, and a plurality of water-saving filling pipes are provided between the filter upper seat and the filter lower seat, and a water collecting pipe is provided on the outer side of the water-saving filling pipe, and the filter assembly is installed between the water-saving filling pipe and the water collecting pipe, and the bottom end of the water collecting pipe is connected to a first outlet opened on the filter lower seat, and a water collecting tray is provided below the filter lower seat, and a second outlet connected to the liquid outlet is provided on the water collecting tray; the filter assembly includes a filter material frame and a filter medium, the bottom of the filter material frame is fixed in the positioning groove of the filter lower seat, and the top of the filter medium is fixed to the filter upper seat through a filter bag pressure plate.

[0004] The above technical solution provides a flow guide assembly for installing the filter assembly inside the filter, so that the flow path of the liquid is restricted to the space between the water-saving filling pipe and the water collecting pipe, thereby effectively preventing the liquid from entering other structures inside the filter.

[0005] However, after the upper cover in the above technical solution is placed on the filter, the upper cover and the connection holes provided on the filter need to be aligned and fixed by bolts. This connection structure is complicated to operate, time-consuming and labor-intensive.

[0006] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Summary of the invention
