Description

A water flow agitating pump for cleaning and purifying machines

【Technical field】

The invention relates to cleaning and purification technology, in particular to a water flow stirring pump for cleaning and purifying machines.

【Background technique】

With the development of society, the life of residents is getting better and better, and the dishes on people's table have become more diverse. Because most vegetables are now sprayed with pesticides or fertilizers, if they are not cleaned and eaten, it will pose a threat to people's health. In addition, in addition to vegetables, fruits, rice, meat and other foods also need to be thoroughly cleaned and disinfected, both families and restaurants will face this cleaning problem. In daily life, there are two main ways to clean food, one is manual cleaning and the other is machine cleaning; the traditional manual cleaning method is to soak vegetables, fruits and other foods in clean water and then rinse, but this cleaning method does not It cannot completely remove harmful substances such as pesticides and bacteria from food; if you use food cleaning agents, there are also problems, because food cleaning agents themselves are chemicals. Although it can kill some bacteria, it is similar to green vegetables with wrinkles. Food and folds are not easy to be washed, but new toxic substances are added. Traditional hand washing is labor-intensive and has poor cleaning effect. It is not only time-consuming, laborious, unclean, but also wastes water. Thoroughly remove the residual pesticides, bacteria, parasite eggs and other harmful substances, causing huge hidden dangers to people's health.

Existing machine cleaning mostly adopts mechanical stirring type, water flushing type or ozone disinfection type; among them, mechanical stirring type and water flushing type treat the cleaning food with great damage, nutrient loss, power consumption and water consumption, and cannot be effectively realized. The disadvantages of using ozone to treat pesticide residues and microorganisms attached to food are: the concentration of ozone is not easy to control, and the solubility of ozone in water is small, and excess ozone is released into the air, which will cause human harm after being inhaled.

The above cleaning methods, in the actual cleaning process, whether it is manual cleaning or machine cleaning, usually can only be soaked or sprayed. The way these water flows act on fruits and vegetables may cause accumulation of fruits and vegetables. A small number of fruits and vegetables have a certain cleaning effect, but for those fruits and vegetables with a large number of surfaces, such as leafy vegetables, it is difficult to achieve a better cleaning effect.

In addition, in the field of electrochemical technology, water can generate hydroxyl radicals under the action of electrodes, which are formed by the loss of an electron from hydroxide. Since the hydroxyl radical (·OH) is an atomic group with an unpaired electron, it has a strong ability to obtain electrons, that is, it has a very high oxidation potential, the oxidation potential is 2.8v, and its oxidation ability is extremely strong, second only to that of fluorine. oxidative capacity. The hydroxyl radical reacts with organic matter, and can oxidize it to generate stable substances that are harmless to the human body, such as oxygen, carbon dioxide, water, and mineral salts. Therefore, it can be used for purification, disinfection, sterilization, and food cleaning with high safety and cleaning. Complete effect, and can save a lot of electricity and water resources. However, in the existing hydroxyl radical purification system, when the cleaning water flows through the generator pole piece, the "water hydroxyl functional group" produced by the pole piece is carried from the hole of the generator shell to the cleaning container. Because the "water hydroxyl functional group" has a very short lifespan, it can only exist in water for a few seconds. Because the existing pole piece structure has no power circulation and diffusion device, the ions generated by the generator aggregate into clusters in the water to form ion clouds, resulting in The uneven distribution of ions in the water makes it difficult to quickly diffuse the "water hydroxyl functional group" into the cleaning container. Due to the uneven diffusion of the "water hydroxyl functional group", the purification effect is affected. On the other hand, in order to achieve a high-efficiency purification effect, a large-area pole piece is required to generate enough water hydroxyl functional groups, so the existing hydroxyl radical purification system needs to have a large volume, which is inconvenient to use.
