Description

Multilayer intakes submerged centrifugal pump

The present invention relates to a multi-layer suction submersible transfer pump, and more particularly, a large storage tank in the bay such as a shrimp farm (festival type) or an oyster farm (Tongyeong, etc.) Seawater close to the surface is generally called surface water, and as the water depth increases, the water temperature inclines and is distributed. Oxygen deficiency in the lower layers and the disconnected cycle caused by the breakage of the natural circulation cycle by It relates to a pump that sucks and transports water from layers with different distributions).

In the case of open land or deep-water aquaculture farms, there is a poor oxygen layer due to non-uniform distribution of dissolved oxygen in the water, or damage caused by excessive immersion in a certain part of the feed, etc. In order to prevent this, a lot of water wheel (windmill type oxygen supply device driven by a motor) is used, and a few air injection devices are installed in the water to operate the farm.

These open-air farms have a quadrangular structure with a maximum left and right length of 200 m or more, and a maximum water depth of 3 m. It was distributed in a circular structure so that when the aberration turns, the water flow is formed in a circular shape.

It is not only domestic farms, but all farms around the world are operating in this type, but it was confirmed that shrimps were not inhabited in the center of the farm (more than 1/3 of the total farm area) by visiting the actual shrimp farm. It is said that it inhabits mainly in the fringe area avoiding the . The reason is judged to be two. The first is that residual food accumulates in the center and causes decay in the water, which interferes with the vegetation of shrimp (all aquatic organisms).

This can be a factor for easy disease infection, and there may be restrictions in which at least 25% of the total area cannot be used for aquaculture, which ultimately increases the production cost.

Therefore, it was necessary to install the above-mentioned development device and transport the floating materials to be deposited on the central low level to a point with relatively high water flow. has occurred.
