Description

Technical Field

[0001] The invention relates to the technical field of filtering equipment, and in particular to a filter element capable of spiral filtering. Background Art

[0002] The filter element is a filtering device for purifying the original fluid. It is provided with a filling filter material for filtering in the filter layer of the filter element, so that the original fluid can separate or remove impurities or certain substances in the original fluid when it flows through the filter material. The existing filter element has a short spacing between the filter layers, so that when the fluid flows through quickly, the filter material in the filter layer cannot fully separate or remove impurities or certain substances in the original fluid, resulting in poor filtering effect. At the same time, the selection of filter material and the filling setting of the filter material will also affect the filtering effect of the filter element. The existing filter element has the problem of poor filtering effect. Summary of the invention

[0003] The object of the present invention is to provide a filter element capable of spiral filtration, wherein a vortex space for causing the fluid to form a swirl and a second filter component for filtering are provided in the cavity within the filter element body, and filter material is provided in the vortex space so that the fluid can fully react with the filter material during the swirl process to improve the filtration effect, and the second filter component is used to further filter the fluid, which can effectively improve the filtration effect and improve the quality of the fluid.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a filter element capable of spiral filtration, comprising a filter element body, a cavity is arranged in the filter element body, and a water inlet and a water outlet connected to the cavity are arranged on the filter element body; in particular, a clean water space and a vortex space are formed in the cavity, the clean water space is connected to the water outlet, a second filter component for filtering fluid is arranged between the clean water space and the vortex space, and the second filter component is filled with a second filter material; a vortex element that can make the fluid form a vortex is arranged in the vortex space, and the vortex space is filled with a first filter material; a water inlet channel connected to the water inlet is also arranged in the cavity, and the water inlet channel passes through the second filter component and extends to be connected to the vortex space.

[0005] The working principle of the present invention is as follows: the filter element capable of spiral filtration forms a clean water space and a vortex space in the cavity inside the filter element body, and a second filter component is arranged between them. When the fluid enters the vortex space through the water inlet and the water inlet channel, the vortex space can cause the fluid to form a vortex, and fully react with the first filter material arranged in the vortex space during the vortex process, which can effectively improve the filtering effect; at the same time, the filter element is provided with a second filter component. When the fluid passes through the vortex space, the rear port enters the second filter component, and the second filter material arranged in the second filter component performs secondary filtration on the fluid, further improving the filtering effect. Finally, the fluid enters the clean water space after passing through the second filter component, and flows out through the water outlet connected to the clean water space. The filter element can effectively improve the filtering effect and improve the quality of the fluid.

[0006] In order to improve the filtering effect of the filter material, preferably, the second filter material is a filter material with a granular surface profile. The second filter material with a granular surface profile can effectively increase the contact area between the filter material and the fluid, so that the fluid can react more fully with the second filter material when passing through the filter material, thereby improving the filtering effect of the filter material.

[0007] In order to further improve the filtering effect of the filter material, preferably, the first filter material is a filter material with a granular surface profile and can flow with the fluid. In this way, the first filter material can not only further increase the contact area between the filter material and the fluid, but also increase the reaction time with the flow of the fluid, so that the fluid can further react with the first filter material when passing through the filter material, thereby improving the filtering effect of the filter material.

[0008] In order to make the structure of the filter element more compact, preferably, the clean water space and the vortex space are arranged in the cavity in an up-and-down arrangement, and the second filter assembly separates the clean water space and the vortex space. The design is that the fluid first passes through the vortex space filter layer, flows through the filter layer of the second filter assembly, and reaches the clean water layer after secondary filtration. Such an arrangement of the inner cavity space arranged up and down is not only simple and reasonable, but also very compact in structure.

[0009] In order to realize the design of the fluid inlet flow direction, preferably, a water inlet pipe extending to the bottom of the cavity is provided in the cavity, and the water inlet flow channel is formed in the water inlet pipe; the second filter component is sleeved on the water inlet pipe and sealed and isolated from the water inlet flow channel. Such a design ensures that when the fluid passes through the water inlet pipe and the water inlet flow channel through the second filter component to reach the vortex space filter layer, it does not interfere with the second filter component, thereby realizing the design of the fluid inlet flow direction.

[0010] In order to limit the installation position of the second filter assembly in the direction of the vortex space, preferably, a top block that can limit the position of the second filter assembly is provided on the water inlet pipe, and the top block is connected to the side of the second filter assembly facing the vortex space. The support force provided by the top block limits the movement of the second filter assembly toward the vortex space. Furthermore, the second filter assembly includes a first partition plate and a second partition plate that are connected to each other, and a step opening that can support the first partition plate is provided in the cavity, and the first partition plate is placed on the step opening. The step opening is provided to support the first partition plate, thereby limiting the installation position of the second filter assembly.

[0011] In order to meet the space requirement for filling the second filter material, preferably, the first partition plate and the second partition plate are parallel to each other, a filter material space for filling the second filter material is formed between the first partition plate and the second partition plate, and the second filter material is densely filled in the filter material space. The first partition plate and the second partition plate are provided to separate and form a filter material space for filling the second filter material, and the filter material is filled in the filter material space, and the density of the densely filled filter material can reach that when the fluid flows through the filter material, the filter material will not move with the fluid.

[0012] In order to limit the position of the first partition plate and the second partition plate, preferably, an elastic device for forcing the first partition plate and the second partition plate to be pressed against each other is provided between the second filter assembly and the filter element body, and the elastic device is located in the clean water space. The elastic device provided in the clean water space is used to provide external force to fix the first partition plate and the second partition plate, thereby limiting the position of the first partition plate and the second partition plate.

[0013] In order to avoid deviation in the elastic direction, preferably, a guide member is provided in the water purification space to guide the elastic change direction of the elastic device. By providing the guide member, the elastic direction of the elastic device can be fixed to avoid the situation where the elastic direction is lateral and so on, thereby being able to position the first partition plate and the second partition plate. It should be noted that the guide member can be a separately provided component, and in order to make the internal structure of the filter element simpler, it can also be provided as a water inlet pipe.

[0014] The implementation of the present invention provides an effective effect: through the vortex space set in the filter element and the first filter material set in the vortex space, the fluid can fully react with the filter material during the vortex process when flowing through, and at the same time, the fluid is filtered for a second time using the set second filter material. The filter element can effectively improve the filtering effect and improve the quality of the fluid. BRIEF DESCRIPTION OF THE DRAWINGS

The second filter material with a granular surface profile can effectively increase the contact area between the filter material and the fluid, so that the fluid can react more fully with the second filter material when passing through the filter material, thereby improving the filtering effect of the filter material.

[0023] Magnesium oxide is a filter material with a granular surface profile that can flow with the fluid. In this way, magnesium oxide can not only further increase the contact area between the filter material and the fluid, but also increase the reaction time with the flow of the fluid, so that the fluid can further react with the magnesium oxide when passing through the filter material, thereby improving the filtering effect of the filter material.

The first partition plate 12 and the second partition plate 13 are provided to separate and form a filter material space for filling the second filter material, and the filter material is filled in the filter material space, and the density of the densely filled filter material can reach that when the fluid flows through the filter material, the filter material will not move with the fluid.
