Description
Technical field
The present invention relates to a kind of heating installation of pig farm, specifically relate to a kind of pig farm electric hot plate and temperature control system thereof.
Background technology
The cold tolerance of piglet is poor, cold weather the time, need the heating facility be set at pig house in the winter time, to guarantee growing up healthy and sound of piglet, improves the survival rate of piglet.
The electric hot plate temperature control system is made up of electric hot plate and thermostat usually, utilizes permanent power heating line to heat, and carries out temperature control with thermostat.Because it has advantages such as temperature is even, health is comfortable, operating cost is low, has had the part pig farm to be applied to the heating on obstetric table moist closet, piglet child care hurdle etc. at present.
Electric hot plate in the conventional art has two kinds: a kind ofly is made up of the cement layer more than the thickness 4cm, heating line and heat-insulation layer, because cement layer is thicker, the heat of the line generation of generating heat is wasted in the transmission course of cement layer to a great extent; Shortcomings such as another kind is the fiberglass electric hot plate, and its existence can not temperature control, the life-span is short.
I the Chinese patent CN 201667723U of application discloses a kind of electric hot plate for the pig farm ground heating system; described electric hot plate comprises shell, heating line, heat-insulation layer and protective layer; the heating line is tiled in case back, and shell, heat-insulation layer and protective layer are fixedlyed connected in turn.A kind of pig farm ground heating system that adopts described electric hot plate, described pig farm ground heating system comprises electric hot plate and thermostat, described electric hot plate comprises a mainboard and some subplates, fastens between mainboard and subplate and subplate and the subplate to form.Electric hot plate heat transfer efficiency height of the present invention, thermal loss is little, and the pig farm ground heating system can be accomplished accurate temperature controlling.But because this electric hot plate is provided with division board, making on the panel of electric hot plate has a projection, can feel uncomfortable when piglet sleeps in the above like this.
Chinese patent CN201599868U discloses the warm plate of a kind of temperature control, and temperature probe is arranged in the groove of panel bottom surface.Because the body temperature temperature of pig is about 35 ℃, and the requirement that counter plate is heated generally is the body temperature temperature that is lower than pig.In case pig sleep the probe directly over panel on, though also not reaching, the panel actual temperature do not arrange by temperature, but because the radiation of pig body heat or conduction, the temperature that probe records is probably greater than arranging by temperature, thereby cause thermostat to be closed in advance, thermostat is not worked, and causes whole heating system to be in closed condition.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of pig farm of can accurate temperature controlling and having a smooth panel with electric hot plate and temperature control system thereof.
A kind of pig farm electric hot plate, described electric hot plate comprises panel, heat-insulation layer and protective layer, the tiling of panel back is provided with the heating line, panel, heat-insulation layer and protective layer from top to bottom are connected in turn, described panel is tabular on the whole, and having a place at least is the groove shape, and this bottom portion of groove protrudes from heat-insulation layer, protective layer is provided with opening corresponding to the position of groove, and the groove cavities top is coated with a heat-conducting plate; The groove back is provided with temperature-sensing probe, and protective layer opening below is equipped with baffle, has a determining deviation between temperature-sensing probe and the baffle, and baffle one side is provided with wire hole.
