Description

MINUTENESS-BUBBLE GENERATION PUMP [0002]

The present invention relates to a micro-bubble generating micro-bubble generating pump, and more particularly, to a micro-bubble generating micro-bubble generating pump which is installed in water to improve contaminated water quality such as red tide and green tide, To a pump for generating minute bubbles.

Generally, when red tides, green tides occur in the sea or river, or water pollution is caused by other pollutants, the amount of dissolved oxygen is drastically reduced, causing the fish to die and the aquatic plants not to grow.

Furthermore, in the case of a caged fish farm, the catches of fish, seaweeds or shellfish rapidly decrease due to red tide or green tide, or they cause a great loss of money due to the death of the fish. If fishes and shellfishes are left unattended, It is true.

In Korea, the red tide phenomenon is reduced by spraying yellow soil on the red tide area in Korea. However, there are reports that the yellow soil may harm the marine ecosystem, In the United States.

Therefore, instead of spraying loess, a method of artificially generating micro-bubbles in water to remove contaminants such as red tides is being sought. The principle is to generate bubbles in the water and raise the bubbles to the surface - Biodiversity is combined with air bubbles to float on the surface, then kicked it out or exposed to sunlight to kill the way.

As a related art related to generating bubbles in water, a Korean Registered Utility Model No. 0203110 (Patent Document 1) has an electronic valve installed inside the case and a diaphragm provided at an inlet and an outlet of an electronic valve, A bubble generator for generating air bubbles in the water after sucking outside air is provided with a base plate with a sound absorbing rubber plate attached to the bottom of the bottom of the bottom case and a plurality of buffer plates And an electromagnetic valve housing formed in a hollow shape and fitted with an electromagnetic valve main body is installed on the inner side of the housing. An electromagnetic valve cap formed as an injection molded synthetic resin material is provided on the electromagnetic valve housing, A pump has been proposed.

However, in the case of the air pump as in Patent Document 1, bubbles are generated in the aeration tank and the wastewater can be purified. However, since the bubble size is large, there is a limit to increase the amount of dissolved oxygen and not micro- There is a problem in that it can not effectively remove fine algae such as red tide creatures.

Conventionally, a pump capable of generating micro-bubbles in units of micrometers has been proposed. However, these equipments are very expensive and thus have no price competitiveness and are difficult to purchase in micro-farms.
