Multi-function device used for intensive shrimp farming and intensive shrimp farming system using this device

A multi-function device for intensive shrimp farming, comprising of:

• a support frame to support the other parts of the device;
• a water flow generator to create water flows in layers with a decreasing volumetric flow rate from the bottom to the surface of the shrimp pond, comprising of an impeller, a motor driving the impeller through a drive shaft, a body covering outside of said impeller that is configured to have a flat plate curved in a semicircle for catching the water flow inside, and the whole said body that has a screw-shaped tubular structure that is convenient for creating and guiding water flows;
• a feeder unit for providing industrial and functional food for shrimp, comprising of the first container, a lid above the first container, a food sensor inside said first container, which can sense the amount of food inside, a feed output below said first container, and a feed dosing motor that is placed on the top of said feed output;
• a substances-supplying unit for delivering substances such as minerals, micro-organisms and other additives into the shrimp pond environment, comprising a second container, a crossbar on top of said second container, a stirring motor located in the middle of the said crossbar, a pipe below said second container for leading the solution of substances to an outlet, and an automatic valve located on the said pipe for controlling the amount of substance to be supplied;
• a gas dissolving unit for diffusing oxygen into water, comprising of at-least a porous ceramic tube, a stainless steel pipe comprising of boles placed inside said porous ceramic tube, gap between said stainless steel pipe and the porous ceramic tube filled with sand, stainless steel bars arranged around said porous ceramic tube, wherein these are held together through rubber fasteners, and round flat stainless steel plates, bolts, and trivets;
• a sensor for measuring water quality including dissolved oxygen concentration, pH, salinity, water temperature, turbidity, and sunlight;
• and
• a controller to operate the multi-function device, to connect and communicate with other components via wiring and/or wireless communication such as Wifi, 3G, 4G or LoRa, wherein said controller being operable to receive, from the sensor, system data information, then determine and adjust the appropriate parameters, and transmit the information to the components to enable the components to operate according to defined parameters.
