Problems solved by technology

It can be seen from the figure that the water inlet of the spiral water filter assembly is at the lower end, and the water outlet is at the upper end. The above-mentioned spiral body) is rotated, and it is not suitable for the filtration method that uses gravity to make the water flow from top to bottom, because when using a piece of spiral body, if the number of turns of the spiral body around the core of the spiral body is too many in a certain space, the slope on the spiral body is too high If the number of turns of the spiral body around the spiral body core is too small, due to the effect of gravity, the water flow will only flow through the filter material close to the spiral body, making the use of the filter material uneven, resulting in filter material failure. waste

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1 to Figure 2 As shown, a spiral filter is composed of a filter element housing 1, a filter medium 2 and a spiral body assembly, and the filter medium 2 and the spiral body assembly are arranged in the filter element housing 1;

[0028] The helix assembly is composed of helix blades 3 and helix core 4; the helix core 4 is a hollow cylinder with a sealed bottom, and the helix core 4 is filled with anti-corrosion materials 5, and the side wall of the helix core 4 has 8 small holes 6, and the upper part of the helix core 4 is made of a helix Core cap 7 covers, and the diameter of spiral body core cap 7 is equal to the internal diameter of spiral body core 4, and spiral body core 4 is used for compressing anticorrosion material 5, and spiral body core cap 7 is the cylinder that has through hole in the middle. When the filtrate flows out...

Abstract

The invention discloses a spiral filter which consists of a filter element casing, a filter medium and a spiral body component, wherein the filter medium and the spiral body component are arranged in the filter element casing; the spiral body component consists of 2 to 6 spiral bodies and a spiral body core; the spiral body core is cylindrical, and the 2 to 6 spiral bodies are arranged around the spiral body core; each spiral body rotates around the spiral body core in parallel; the edges of the spiral bodies are seamlessly attached to the inner wall of the filter element casing; the space between the spiral bodies is filled with the filter medium. According to the spiral filter, the defects of incapability in smooth circulation of a filtered material and particularly excessively long filtering time and even filtering incapability of the filtered material under a low-pressure condition due to adoption of a single spiral body are overcome, the practical problems of difficulty and even incapability in filling of the filter medium due to adoption of the single spiral body are also solved, the filtering path is prolonged to a certain extent, and the filtering effects are improved.

Description

technical field [0001] The invention specifically relates to a spiral filter and belongs to the field of filtering equipment. Background technique [0002] Filtration equipment is a kind of equipment widely used in daily life and industrial processes. The filtering equipment in the prior art is generally straight cylindrical filtering equipment, the filtering path is relatively long, the space occupied is relatively large and the straight cylindrical filtering equipment may It will cause problems such as uneven use of the filter medium. [0003] The application number is 201110304606.0, and the Chinese patent spiral water filter assembly with publication number 102309875A discloses a spiral water filter assembly, which includes a filter material and a filter shell with a water inlet and a water outlet. The filter shell has a spiral inner core. The outer edge of the spiral inner core fits closely with the inner wall of the filter element shell, and the filter material is pla...
