Water body oxygen-increasing circulation device with auxiliary heating function

Abstract

The invention discloses a water body oxygen-increasing circulation device with an auxiliary heating function, and belongs to the technical field of water for agriculture or cultivation. The water body oxygen-increasing circulation device with the auxiliary heating function comprises a water tank, a gas producing unit and a heating unit; a water supply pipe and a liquid outlet pipe are arranged at the side ends of the water tank correspondingly; the gas producing unit comprises an air compressor, a gas liquid mixed pressurizing dissolution tank, an ultrasonic cavitation device and a gas liquid rotating cylinder; the air compressor communicates with the gas liquid mixed pressurizing dissolution tank through a gas inlet pipe; a motor is arranged at the top end of the gas liquid rotating cylinder; the gas liquid mixed pressurizing dissolution tank communicates with the water tank through a water inlet pipe; a water pump I is arranged on the water inlet pipe; the gas liquid mixed pressurizing dissolution tank, the ultrasonic cavitation device and the gas liquid rotating cylinder communicate with one another sequentially through a pipeline I and a pipeline II; the gas liquid rotating cylinder communicates with the water tank through a water outlet pipe; and the heating unit comprises an electric heating wire positioned at the bottom of the water tank. The water body oxygen-increasing circulation device with the auxiliary heating function can meet double requirements of high yield and temperature rising of microbubble circulation, is high in oxygen-increasing efficiency, and can be applied to actual application production such as farm irrigation and aquaculture, or experimental research.

Description

technical field [0001] The invention relates to the technical field of water for agriculture or aquaculture, in particular to a water aeration circulation device with auxiliary heat function. Background technique [0002] Agricultural irrigation and aquaculture and other fields need to use technical measures such as increasing oxygen and gas in water, increasing temperature and heat preservation. Existing studies have shown that the smaller the bubbles, the slower their rising speed in the water body and the longer their existence time. Based on this, the prior art has successively proposed methods for crushing bubbles such as pressurized dissolution, gas-liquid spinning, and ultrasonic cavitation. Under this theoretical technology, there are reports of micro-nano bubble generators, etc., but these devices often only use a single gas production method, which is still limited in the number and particle size of the bubbles, and the comprehensive effect needs to be improved. ...

Problems solved by technology

[0005] The effect is obvious. Photovoltaic-wind power generation equipment can be used to provide power, which is environmentally friendly and energy-saving. It can not only be used as a new technology for oxygenation irrigation, but also can be used for high-efficiency oxygenation in fish farming, effectively solving the defects of low efficiency and high energy consumption of the oxygen supply system for aquaculture. ; But this device is to carry out high-pressure aeration to the water flow that enters the microbubble generation cavity by Venturi tube microbubble generator, and method is single

[0006] In addition, many of these devices only consider the measures of increasing oxygen and gas, while ignoring the technology of increasing temperature and heat preservation. They lack a comprehensive device system that considers both increasing oxygen and gas and increasing temperature and heat preservation. It has the function of increasing temperature and heat preservation, but it cannot adapt to different working environments and cannot exert the best effect
