A kind of constant-temperature rearing pond
Technical field
The present invention relates to cultural technique field, be specifically related to a kind of constant-temperature rearing pond.
Background technology
At present, the more and more subtilized change of aquaculture.For some aquatic livestock, especially plant seedling stage, need to carry out cultivating or cultivating under constant temperature, but when atmospheric temperature constantly changes, the water temperature in fishpond is difficult to the demand reaching constant temperature cultivation, thus affects aquaculture effect.And existing fishpond hot water used utilizes combustion gas or electricity to heat often, to ensure that water temperature in fishpond is in relatively more suitable temperature, the fishpond that especially fry is special, high to the requirement of temperature, slightly deviation will fry sick or dead.And be use electrical heating or coal-fired heating all can slattern a lot of energy pollution environment, and the cost used is also higher, makes expending of constant-temperature rearing pond very high.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of constant-temperature rearing pond, this constant-temperature rearing pond to the water circulation heating in fishpond, solves the problem that fishpond heating cost is higher by solar thermal collector.
The present invention is achieved by the following technical programs.
A kind of constant-temperature rearing pond provided by the invention, comprises fishpond sidewall, flow distribution plate, heating furnace, circulating pump, solar thermal collector, outlet pipe, heat exchange pond, heat-transfer pipe, circulation pipe and water inlet pipe; Described solar thermal collector provides heat by heat-transfer pipe to heat exchange pond, the one end in described heat exchange pond is by outlet pipe and the cavity connects formed by fishpond sidewall and flow distribution plate, the other end is connected with circulation pipe and water inlet pipe respectively, the other end of described circulation pipe is placed in fishpond, and described circulation pipe runs through flow distribution plate, described circulation pipe is also provided with circulating pump; The other end of described water inlet pipe is connected with heating furnace.
Also filter course is provided with between described fishpond sidewall and flow distribution plate.
Described filter course is filter cotton.
Described water inlet pipe is provided with booster pump.
Described flow distribution plate is many punchings corrosion resistant plate.
Described filter course is pasted onto on the sidewall of flow distribution plate.
Beneficial effect of the present invention is: by solar thermal collector to the water circulation heating in fishpond, keep water temperature; When the heating efficiency of solar thermal collector is limited, take the way of heating furnace auxiliary heating, solve the problem that fishpond heating cost is higher; Meanwhile, between flow distribution plate and fishpond sidewall, be provided with filter course the contaminant filter in the water of fishpond is fallen, keep that water quality in fishpond is limpid, health.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: the sidewall of 1-fishpond, 2-filter course, 3-flow distribution plate, 4-heating furnace, 5-circulating pump, 6-booster pump, 7-solar thermal collector, 8-outlet pipe, 9-heat exchange pond, 10-heat-transfer pipe, 11-circulation pipe, 12-water inlet pipe.
Embodiment
Further describe technical scheme of the present invention below, but described in claimed scope is not limited to.
A kind of constant-temperature rearing pond as shown in Figure 1, comprises fishpond sidewall 1, flow distribution plate 3, heating furnace 4, circulating pump 5, solar thermal collector 7, outlet pipe 8, heat exchange pond 9, heat-transfer pipe 10, circulation pipe 11 and water inlet pipe 12; Described solar thermal collector 7 provides heat to heat exchange pond 9 by heat-transfer pipe 10, the one end in described heat exchange pond 9 is by outlet pipe 8 and the cavity connects formed by fishpond sidewall 1 and flow distribution plate 3, the other end is connected with circulation pipe 11 and water inlet pipe 12 respectively, the other end of described circulation pipe 11 is placed in fishpond, and described circulation pipe 11 runs through flow distribution plate 3, described circulation pipe 11 is also provided with circulating pump 5; The other end of described water inlet pipe 12 is connected with heating furnace 4.
Filter course 2 is also provided with between described fishpond sidewall 1 and flow distribution plate 3; Described filter course 2 is filter cotton.Described filter course 2 is pasted onto on the sidewall of flow distribution plate 3.Filter course 2 plays certain shunting action to from outlet pipe 8 hot water out, and the particulate contamination (excreta as fish food residue, fish) in water quality is played the effect of filtration by filter course simultaneously, keeps that water quality in fishpond is limpid, health.
Described water inlet pipe 12 is provided with booster pump 6, makes the hot water in heating furnace can enter fishpond by heat exchange pond rapidly, ensure the temperature in fishpond.
Described flow distribution plate 3 is many punchings corrosion resistant plate, and the multiple apertures on flow distribution plate can reduce local water temperature to carrying out from outlet pipe 8 hot water out shunting, avoid fish to be burned; The flow distribution plate of stainless steel is adopted not only to ensure that intensity but also avoid getting rusty.
The present invention to the water circulation heating in fishpond, keeps water temperature by solar thermal collector; When the heating efficiency of solar thermal collector is limited, take the way of heating furnace auxiliary heating, solve the problem that fishpond heating cost is higher; Meanwhile, between flow distribution plate and fishpond sidewall, be provided with filter course the contaminant filter in the water of fishpond is fallen, keep that water quality in fishpond is limpid, health.
