Description

Technical Field

[0001] This utility model relates to the technical field of filters, and in particular to a filter with a wound wire filter element. Background Technology

[0002] Angle filters are used to filter impurities in liquid media. The filter element can be disassembled in time to achieve the effect of periodic cleaning of impurities. It is a common type of filter in water supply systems. Traditional angle filters usually use sintered mesh cylinders as filter elements. They are made by weaving and sintering metal wire mesh, which makes the internal mesh holes interlaced. It is extremely difficult to clean the impurities attached to the mesh holes. Over time, they are prone to deterioration and are not suitable for filtering food-grade filtration systems such as milk, beverages, and wine. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the technical solution adopted by this utility model is as follows: a filter with a wound filter element, including a filter barrel, a mounting frame, a wound filter element, end caps, positioning caps, sealing elements, and nuts. The filter barrel is provided with vertically distributed liquid inlets and outlets. The mounting frame is fitted with a wound filter element for filtration. The mounting frame is provided with end caps and positioning caps at both ends of the wound filter element. The positioning caps are sealed to the filter barrel through the sealing elements. The liquid inlet is located on the outside of the wound filter element. The inside of the wound filter element is connected to the liquid outlet through the positioning caps. The filter barrel is threaded with nuts, and the mounting frame is snapped between the filter barrel and the nuts through the end caps.

[0004] As a preferred embodiment of this utility model, the mounting frame includes a central rod, and sleeves and bottom covers disposed on both sides of the central rod. The end covers, the wound filter element, and the positioning cover are sequentially sleeved between the sleeves and the bottom cover. The bottom cover is provided with through holes for the flow of liquid medium around the central rod.

[0005] Specifically, the sleeve is provided with an internal thread, the central rod is threaded to the sleeve through the internal thread, and the central rod is provided with a stepped surface for limiting the position. The end cover is provided with a first arc groove for locking the wire-wound filter element, and the two sides of the positioning cover are respectively provided with a second arc groove and a third arc groove for locking the wire-wound filter element and the bottom cover.

[0006] Using the above technical solution, during installation, the positioning cover, the wound filter element, and the end cover are sequentially fitted onto the central rod. The positioning cover, the wound filter element, the end cover, and the bottom cover are coaxially distributed through the first, second, and third arc grooves. The sleeve is threaded to the central rod and abuts against the stepped surface. The stepped surface makes the distance between the end cover and the positioning cover controllable, and the wound filter element is clamped between the end cover and the positioning cover, preventing the wound filter element from being over-compressed and affecting the filtration effect, thus maintaining the stability of the structure.

[0007] As a preferred embodiment of this utility model, the end cap is provided with an inner hole and an outer ring portion. The end cap is sleeved on the central rod through the inner hole. The filter barrel is provided with an external thread portion. The nut is threadedly connected to the filter barrel through the external thread portion, and the nut and the filter barrel are combined to form a groove for engaging the outer ring portion.

[0008] Specifically, the center rod has a first sealing groove for installing a sealing ring at the inner hole, and the external threaded part has a second sealing groove for installing a sealing ring.

[0009] By adopting the above technical solution, the sealing performance of the filter barrel at the external threaded part is improved by the sealing rings in the first sealing groove and the second sealing groove, thus preventing the liquid medium inside the filter barrel from overflowing.

[0010] As a preferred embodiment of this utility model, the wire-wound filter element is a stainless steel square wire mesh bent into a cylindrical shape.

[0011] By adopting the above technical solution, the filter screen is bent into a ring shape, which has a simple overall structure and is easy to process, increases the filtration area, and is easy to clean.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The liquid medium flows into the filter barrel from the inlet, passes through the wound filter element and flows out from the outlet. The surface of the wound filter element has multiple parallel steel rings, and there are gaps between the steel rings for filtration. When the liquid medium flows from the outside of the wound filter element to the inside through the gaps, large particles of impurities are filtered out by the wound filter element. The filtered liquid medium passes through the positioning cover and the bottom cover and flows out from the outlet. Its filter element has a large filtration area, which improves the filtration efficiency.

[0014] 2. When the filter element needs to be cleaned, unscrew the nut and pull the mounting frame out of the filter canister. At this time, the impurities on the inner wall of the filter canister will also be pushed out by the seal. Use the cleaning brush to clean the filter element by rotating it in a circular motion along the gap of the filter element. The cleaning method is simple and can be reused.

[0015] The embodiments of this utility model will be further described below with reference to the accompanying drawings. Attached Figure Description
