That is, as the medium passes through the chamber 102 and gradually expands outward from the medium inlet 101 toward the medium outlet 103, the distance from the central rotation axis of the medium passing hole gradually increases.

The rotatable filter plate 2 and the fixed filter plate 5 are both made of copper-based catalyst alloy with an anti-scaling function.

It should be noted that, in the copper-based catalyst alloy with the anti-scaling function, the copper-based catalyst alloy forms a columnar crystal structure with consistent orientation in the copper-based catalyst alloy by strictly controlling the component ratios of various elements and adopting a thermal processing process, so that the copper-based catalyst alloy has the unique functions of extremely strong release of free electrons to a water medium and polarization effect of the water medium. When water flows through the copper-based catalyst alloy at a certain flow velocity, the copper-based catalyst alloy can release electrons to the water, change the static potential of the fluid, enable the water to generate a polarization phenomenon, and enable anions and cations in the water not to be easily combined to form scale. The copper-based catalyst alloy comprises the following materials in percentage by weight: cu: 40% -70%, Ni: 5% -20%, Zn: 10% -35%, Sn: 5% -30%, Ag: 0.5% -20%, Fe: 0.1-8%, Sb: 0.01% -2%, Mn: 0.05-5%, and the components are compounded to form columnar crystal alloy growing along the S100 crystal axis. Under the condition of not changing water body components and pH value, the scale formation index is reduced by continuously releasing free electrons to reduce the cation concentration of the water body, thereby achieving the purpose of scale inhibition. The Cu-Ni binary alloy has excellent chemical stability, excellent corrosion resistance in various environments, excellent cold and hot processing performance and moderate cost. Although the electronegativity of the Cu-Ni alloy system is smaller than that of the solution, the electron losing ability is not strong due to the good chemical stability. Therefore, Zn and Ag elements are selected as alloy elements to be added on the basis of the Cu-Ni binary alloy. Wherein, the electronegativity of Zn element is 1.65, which is one of the metal elements with the lowest electronegativity in common elements, and can form stable ternary alloy with Cu-Ni alloy. Ag is 2.34 electronegativity, and is one of the most electronegative alloy elements except rare earth and radioactive elements. Ag is almost insoluble in Cu-Ni-Zn alloy, mainly appears in a free state, can obtain an ideal distribution state through reasonable component control and a hot working process, and is an ideal cathode material. The activation current gradually increases with increasing Ag content. The larger the activation current is, the stronger the ability of releasing electrons is, the less the copper-based catalyst alloy dosage per unit flow is, and the overall cost is more advantageous.

The preparation method of the copper-based catalyst alloy comprises the following steps:

1. preparing raw materials according to the weight percentage of the components, wherein the raw materials are blocks with the purity of more than 99.9 percent and the volume of the blocks is less than or equal to 2cm³；

2. Charcoal with the thickness of 1 cm-3 cm is laid in a crucible of an induction furnace, half of a Cu material is uniformly laid on the charcoal by weight, then all Ni blocks are uniformly laid on the Cu material, then the charcoal with the thickness of 1 cm-3 cm is laid, the furnace is opened, the temperature is raised to 900 ℃ -1100 ℃, after all metals are melted, all Fe and Sb blocks are added, the mixture is stirred until all metals are melted, all Mn blocks are added, and the temperature is kept for 3 minutes-8 minutes to degas the molten metal;

3. and then adding Zn, Sn, Ag and the rest Cu in sequence, stirring at a low speed, removing scum after the metal is completely melted, reducing the temperature of the melt to 1150-1280 ℃, pouring the melt metal into a casting mold, cooling for 5-15 minutes until the metal surface is crusted to form a metal ingot, cooling to room temperature by water, and taking out the metal ingot to obtain the copper-based catalyst alloy.
