Fishpond device heating by using underground water

Abstract

The invention relates to a fishpond device heating by using underground water, comprising a fishpond, a water inlet pipe, a water outlet pipe and automatic constant-temperature water mixing valves, a temperature sensor which is controlled by an automatic control device, an electrically operated valve and a deep water pump. The fishpond device is characterized by also comprising a deep well which is communicated with the deep water pump and used as a heat supply source and a high-place pond which is used for providing low-temperature water. A thermal insulation layer, a heating coil which is fixed on a steel wire mesh, a filling layer which is used for filling the heating coil, a leveling layer and a surface layer arranged in the fishpond in sequence from the bottom up. The automatic constant-temperature water mixing valves are arranged at pipe junctions of high-temperature underground water of the deep well and low-temperature water of the high-place pond. The water inlet pipe which has a plurality of orifices and directions is arranged on the side wall of the fishpond. Obviously, the fishpond device is capable of singly controlling the water temperature in each fishpond and satisfying the demand of farming fishes suitable for different temperatures, so that the energy consumption and environment pollution are greatly decreased, benefit is brought to energy conservation and emission reduction and the utilization form of the underground water is developed.

Description

technical field [0001] The invention belongs to industrialized aquaculture devices, in particular to a fish pond device heated by groundwater. Background technique [0002] In aquaculture production, in order to ensure that fish can survive the winter safely and maintain a certain growth rate in winter, it is necessary to supply heat to fish ponds to maintain the water temperature necessary for fish growth. At present, my country's industrial farming mainly uses steam boilers to supply heat to fish ponds, that is, to heat seawater or fresh water through steam boilers, and transport the generated high-temperature steam to the heating pipes laid in the preheating pool to heat up the water body, and then transport the water body to the fish pond For farming. Disadvantages of steam boiler heating: First, the preheating pool occupies a large area and takes up aquaculture space; second, the exhaust gas emitted by the boiler will cause air pollution; third, the coal, fuel, and elec...

Problems solved by technology

Disadvantages of steam boiler heating: First, the preheating pool takes up a lot of land and takes up aquaculture space; second, the exhaust gas emitted by the boiler will cause air pollution; third, the coal, fuel, and electricity used by the boiler increase the cost of aquaculture

However, the chemical composition of groundwater is complex and often contains some harmful components and pollutants, the most prominent of which are fluorine and heavy metals, which have adverse effects on the hygienic quality of cultured animals and do not meet the requirements of healthy farming.
