Abstract
The utility model discloses a kind of delivery room Farrowing house cooling and heating system, comprise heat pump, heat exchanger fin, blower fan, circulating water pipe, valve and support.In summer high temperature season, the utility model freezes water by heat pump, and by circulating line, cold water is transported to the heat exchanger fin of every sow manger top, utilize blower fan that the air of heat exchanger fin precooling is blowed to sow, make sow obtain effective temperature-reducing season at summer high temperature, make sow break away from the impact of heat stress, improve sow production performance.
Description
Technical field
The utility model relates to livestock and poultry cultivation facility technology field, particularly the cooling of a kind of delivery room Farrowing house and heating system.
Background technology
In Farrowing house, comprise sow and suckling pig, wherein for sow, more suitable temperature is 18～25 ℃, and the optimum temperature of piggy is 30～34 ℃.In current sow feeding process, through experimental results demonstrate, the high temperature that high temperature produces stress produce serious harm for sow health, and experiment shows, when temperature is during higher than 30 ℃, sow occurs that obvious high temperature stress show, and is specially sow feed intake and significantly declines, mouth breathing, breathe, prolonged labor, difficult labour rate improves, easily secondary birth canal infects and mastitis infection, and occurs that lactation amount declines, Quality Down etc.Piggy case fatality rate significantly rises.
At present Farrowing house has multiple cooling system or method, these equipment or method to mainly contain negative pressure Wet-curtain temperature reducing system, the cooling etc. of dripping of air-cooler, mist cooling, sow head.But on the whole,, these method cooling-down effects are limited, and negative effect is large.Do not obtain aborning promotion and application widely.Although wherein negative pressure Wet-curtain temperature reducing system can be lowered the temperature, cooling extent is limited, and causes delivery room humidity to increase, and piggy is easily suffered from cold.The pig farm of raising at some subdivisions, delivery room area is little, and is not suitable for installing negative pressure Wet-curtain temperature reducing system, and Wet-curtain temperature reducing system needs pig house sealing property better, and negative pressure cooling system cannot be used in the delivery room of open or semi-open property.Although air-cooler does not require pig house good seal performance, can use at open or semi-open property pig house, cooling-down effect is also little, and negative effect is that wind speed is larger, and high humidity, piggy are easily suffered from cold.Also have selected swine farms to adopt spraying or the cooling of dripping, although these methods have certain effect, cause equally delivery room humidity, the piggy death of easily having loose bowels.
Defect based on this class cooling system, existing patented technology has been recorded the effect that cool cycles water pipe reaches cooling or heating has been installed under obstetric table floor, can be the heating of piggy incubator in the winter time, and be the cooling of sow floor summer.Although this method can consider that piggy and sow are for the difference of temperature requirements preferably, but the shortcoming of the method maximum is to carry out huge change to column home, and necessarily requiring is solid floor, and China's overwhelming majority is sow farrowing bed at present, it is full screen floor for manure, and be not suitable for adopting the method, and the method adopts the method for floor refrigeration to lower the temperature, and effect is limited, and be easy to cause sow belly to suffer from cold and the disease of diarrhoea occurs.
Summary of the invention
In order to solve existing cooling system, be unsuitable for installing, cooling-down effect is not good, easily cause the sick technical problem of piggy, the utility model a kind of easy for installation, good cooling effect is provided and can produce the cooling of dysgenic Farrowing house and heating system to piggy.
In order to realize above-mentioned technical purpose, the technical solution of the utility model is, a kind of delivery room Farrowing house cooling and heating system, comprise source pump, outlet pipe, return pipe, water pump, heat exchanger fin, blower fan and support, described source pump is connected with heat exchanger fin with return pipe by outlet pipe and forms closed circuit, described water pump is arranged on outlet pipe, and described blower fan is fixed on a side of heat exchanger fin, and heat exchanger fin is fixed on the sow farrowing bed place of Farrowing house by support.
Described a kind of delivery room Farrowing house cooling and heating system, also comprise outlet valve and back-water valve (BWV), and described outlet valve is installed on the junction of outlet pipe and heat exchanger fin, and described back-water valve (BWV) is installed on the junction of return pipe and heat exchanger fin.
Described a kind of delivery room Farrowing house cooling and heating system, described heat exchanger fin is fixed on directly over the sow farrowing bed crib of Farrowing house by support, and on heat exchanger fin the outlet air end of fixing fan towards sow farrowing bed.
Described a kind of delivery room Farrowing house cooling and heating system, described heat exchanger fin is identical with the sow farrowing bed quantity of the quantity of fan and Farrowing house.
Technique effect of the present utility model is, at high temperature season, utilizes heat pump that water is freezed, and recycling circulating pump pumps into heat exchanger fin by the water of precooling, utilizes blower fan that the precooled air through heat exchanger fin is blowed to sow.Cooling extent of the present invention is large, can free adjustment, and can significantly reduce delivery room relative moisture, piggy temperature is unaffected.Another advantage of the present utility model is not need existing column home to change, easy for installation simple, has avoided existing patented technology to carry out large transformation to column home, and needs the defect on solid ground.This system is utilized heat pump principle, can greatly improve refrigerating efficiency, in cooling, can also promote the circulation of air, reduces significantly the relative moisture of the air in delivery room, improves greatly the productivity of sow and the survival rate of piggy.Experimental result on a pig farm shows, adopts this cooling method, and when room temperature 32 is spent, with control group comparison, sow feed intake improves 30% than control group, and difficult labour rate declines 15%.21 days average short milk of piggy is heavy compared with control group raising 1.22kg/ head.This system in the winter time time, can also be utilized heat pump or the circulation of boiler supplying hot water, if by blower fan direction facing to incubator, can heat piggy incubator.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is scheme of installation of the present utility model;
Wherein, 1 is source pump; 2 is water circulating pump; 3 is outlet pipe; 4 is return pipe; 5 is outlet valve; 6 is water intaking valve; 7 is heat exchanger fin; 8 is blower fan; 9 is sow farrowing bed; 10 is crib; 11 is support; 12 is aisle.
Embodiment
Referring to Fig. 1, the utility model comprises source pump, outlet pipe, return pipe, water pump, heat exchanger fin, blower fan and support, source pump is connected with heat exchanger fin with return pipe by outlet pipe and forms closed circuit, water pump is arranged on outlet pipe, blower fan is fixed on a side of heat exchanger fin, heat exchanger fin is fixed on the sow farrowing bed place of Farrowing house by support, according to the needs of Various Seasonal, can use cold water circulation and hot water circuit to control temperature in Farrowing house.
In order to realize the temperature at each sow farrowing bed place of independent control, the utility model also comprises outlet valve and back-water valve (BWV), outlet valve is installed on the junction of outlet pipe and heat exchanger fin, back-water valve (BWV) is installed on the junction of return pipe and heat exchanger fin, can whether there is sow to open or closing temperature control according to obstetric table place like this, to reach the object of saving the energy.
