Upward flow circulating water culture system for hirudo

Abstract

The invention belongs to the field of hirudo culture, and particularly relates to an upward flow circulating water culture system for hirudo. The upward flow circulating water culture system comprises a water platform and a culture zone. The water platform comprises a support, a buoyancy tank and pedals, the support is formed in a longitudinal and transverse crossing manner, the buoyancy tank is arranged at the bottom of the support, and the pedals are fixed to the upper surface of the support; the culture zone comprises a drainage channel, a flow pushing pump and a plurality of culture tanks, the culture tanks are arranged on the support, and the drainage channel is arranged among the culture tanks. The upward flow circulating water culture system is characterized in that an inflation hole is formed in the buoyancy tank, and an air release valve is arranged on the buoyancy tank; the culture tanks comprise tank side walls and metal netted tank bottoms; first through holes are formed in the upper portions of the tank side walls; second through holes which correspond to the first through holes are formed in the side walls of the drainage channel, and the first through holes are fixedly connected with the second through holes by water outlet pipes; a drainage pipe is arranged on the lower portion of a side wall of the drainage channel and is connected with the flow pushing pump by a tee joint. The upward flow circulating water culture system has the advantages that water flow in the culture tanks can be effectively circulated and can be in flow states constantly, and accordingly the oxygen content of water can be increased.

Description

technical field [0001] The invention belongs to the field of leech culture, and in particular relates to a leech upflow circulating water culture system. Background technique [0002] Leeches, commonly known as leeches, mainly grow and reproduce in inland freshwater waters, and are one of the important Chinese medicinal materials in my country. Hirudin extracted from leeches has a very significant effect on dilating blood vessels, reducing blood viscosity, and increasing blood circulation. It has been widely used in the treatment of stroke, high blood pressure, dredging, bruises, and other medicines and various health care products. However, due to the rapid reduction of wild leech resources caused by water environmental pollution in recent years, the market price of leeches has also increased year by year. Therefore, in order to solve the increasingly prominent contradiction between supply and demand of leeches and meet the huge social demand for leeches, artificial breedin...
