[0003] At present, the air intake end of the compressor for farming is usually arranged at one end of the volute, resulting in the entire barrel being closed. To cool the rotor inside the compressor, an external air cooling or water cooling device must be connected, which greatly improves The complexity of the device, the assembly is complicated, and the cost is too high. Secondly, the existing device is not equipped with a suitable pressure regulating mechanism. When the air is compressed and blown for different depths and widths of aquaculture waters, it will cause the output end of the fan to be blocked and the rotor to over-rotate , air leakage, or even burnt, which seriously limits the performance of the fan and the efficiency of compressed air blowing

The invention discloses a high-density breeding fan which comprises a machine barrel, a fan blade, a fan blade and a fan blade, and an air inlet is formed in the front end of the machine barrel; the thrust frame is arranged on the air inlet; a thrust plate is arranged in the middle of the thrust frame; the input end of the volute is connected to the rear end of the machine barrel; an impeller is rotatably arranged in the volute; the output end of the volute is connected with an exhaust pipe connected into a culture water area; the electronic pressure regulating valve is connected to the exhaust pipe branch; the rotor is arranged in the middle of the machine barrel in a penetrating manner; the two ends of the rotor are connected with the thrust plate and the impeller respectively. According to the invention, the air inlet of the breeding fan is separated from the volute, automatic air cooling is realized while air intake is realized, and the effect is good; and meanwhile, the stable pressure of the output end of the fan is regulated and controlled through the electronic pressure regulating valve, and stable compressed air oxygen enrichment of the aquaculture water area is achieved.
Description
technical field [0001] The invention relates to the field of related devices for breeding fans, in particular to a high-density breeding fan. Background technique [0002] Breeding fan refers to the compressor for breeding, which blows air into the breeding area through compressed air to meet the needs of breeding. The so-called compressor is a component of a gas turbine engine that uses high-speed rotating blades to perform work on the air to increase air pressure; a compressor The front part of the impeller blade is curved, called the guide wheel, and its function is to introduce the gas into the working impeller without impact to reduce the impact loss of the airflow; the compressor impeller of a small supercharger generally integrates the guide wheel with the working impeller; There is a diffuser at the outlet of the impeller of the compressor, so that the kinetic energy obtained by the gas in the impeller can be converted into pressure as much as possible; the diffuser ...
