A method for making a water alkali filter

　　Fully automatic filter manufacturer introduction: Usually, after boiling raw water such as tap water, water alkali, or scale, will be produced. It refers to the white block-like or powdery substance gradually formed by the minerals contained in hard water adhering to containers (such as pots and kettles). Its main components include calcium carbonate, magnesium hydroxide, and magnesium carbonate. Water alkali has poor thermal conductivity. If the scale formed in the boiler is too thick, the efficiency of the boiler will be reduced. If it is too heavy, the boiler will burst, causing boiler accidents. Water alkali also contains many harmful substances that endanger human health, so raw water is not convenient to drink directly even after boiling; in order to remove water alkali, some people will add some special dealkalizing pads to the boiling container, but their service life is limited, and sometimes when drinking, there is still residual water and alkali flowing out with the water; if chemical substances are added to the water to remove water alkali, it will be more difficult to meet the drinking requirements. How to remove water alkali after boiling raw water and when drinking is still a rather thorny problem to be solved. With the development of society and the advancement of technology, some people have begun to choose to use water alkali Filter to remove water alkali.

　　Technical personnel provide a water alkali filter that can thoroughly remove water alkali from boiled drinking water, making the boiled water clear and clean and ensuring the hygiene of drinking water. To achieve the above purpose, this boiled water alkali filter adopts the following technical scheme: It consists of a funnel-shaped shell and a filtering device installed at the open bottom of the shell. The filtering device consists of a support plate matching the inner diameter of the funnel's upper opening and food-grade filter non-woven fabric sandwiched between two support plates. The support plate is a pressing plate with a filter mesh connected to the bottom surface, and the pressing plate is a plate-like body composed of concentric rings. The support plate, non-woven fabric, and support plate are stacked in order at the bottom of the opening of the shell. When using, Filter place it on the upper opening of the drinking water container, such as the upper opening of the thermos. When boiling water is poured into the container, the water and alkali can be completely blocked on the filtering device, ensuring the hygiene of drinking water, and the filtering device can be removed and cleaned for repeated use.

　　This water alkali filter has the following advantages: 1. Thoroughly remove water and alkali, which is beneficial to hygiene; because the filter shell and filter device are made of non-toxic food-grade materials, the filtered boiled water passes through the microporous filter mesh and non-woven fabric, which can completely block the water and alkali at the filter device at the upper opening of the shell, so the drinking water can be safe and hygienic. 2. Easy to use, easy to clean, durable. Because Filter there are ribs on the outer edge of the lower opening, when boiling water is poured into the container through the filter, the air in the container is easy to discharge, and the ventilation of the support plate and non-woven fabric is also good, and the water flow is smooth during filtration; in addition, because the used filter device is actively stacked in the shell, there is no handle on the support plate, so the assembly and disassembly are convenient, easy to replace and clean, and durable. 3. Simple structure, easy to mass produce, wide range of applications, low production cost, and good social benefits.
