Description
Technical field
The utility model belongs to cereal cooling device, is specifically related to a kind of double-refrigerant integral type grain cooling machine.
Background technology
Low-temperature grain-storage because of have insect protected, antibacterial, delay quality ageing, prevent that the advantages such as pollution are widely used in grain depot.Existing low-temperature grain-storage technology is a kind of is all to adopt the refrigeration plant of electricity consumption that the temperature of silo is carried out cooling and controlled, and energy consumption is high; Another kind is to utilize underground water to lower the temperature as low-temperature receiver, although can save the energy, using energy source is poor, and refrigeration is limited; Have the electric refrigeration of employing equipment to add the scheme of underground water, but due to unreasonable structure, make radiating effect bad, heat energy is not fully utilized yet.Have in view of that, be necessary to develop a kind of saving energy and reduce the cost, can efficiently utilize the energy, the cereal cooling device reducing costs.
Utility model content
The purpose of this utility model is the problem existing for prior art, and the double-refrigerant integral type that a kind of cost is low, energy utilization rate is high grain cooling machine is provided.
The technical scheme that realizes the employing of the utility model object is as follows:
Double-refrigerant integral type grain cooling machine, comprises ventilation unit, the cooling system of underground water and refrigeration system; Described ventilation unit comprise establish air inlet and air outlet casing, be located at the blower fan on air outlet; The cooling system of described underground water comprises water pump, heat exchanger and the water tank connecting successively, and described heat exchanger is located in described casing; Described refrigeration system comprises compressor, the evaporimeter being connected with compressor and condenser, after described evaporimeter is located at and is positioned at heat exchanger in described casing, described condenser comprises the first condenser and the second condenser being connected with the first condenser, after described the first condenser is located at and is positioned at evaporimeter in described casing, described the second condenser is located in described water tank.
In described casing with the corresponding cooling fan that is provided with of described the first condenser.
In described casing, be provided with auxiliary electro-heat device.
After being positioned at the first condenser in casing, locate to be provided with humiture detector, humiture detector is connected with automatic control system with cooling fan.
Described casing air inlet is provided with airstrainer.
The utility model has the following advantages compared with the prior art:
1, energy consumption is low.General equipment all utilizes electric energy acting to utilize the medium cold energy and heat energy is provided, the cold energy that the utility model makes full use of underground water carries out precooling to entering the air of casing, it is cooling that the evaporimeter of recycling refrigeration system carries out secondary to air, heat energy utilization the first condenser that simultaneously rationally reclaims compressor heats the relative humidity that reduces air to air, can save a large amount of power consumptions.
2, good heat dissipation effect.General device heat radiation is all to utilize blower fan to rely on the Air Flow of external environment condition to dispel the heat to realize, consume electric energy, when ambient temperature is high, radiating effect is poor, the utility model utilizes the water tank of the cooling system of underground water to dispel the heat to the second condenser of refrigeration system, because water temperature can too high (≤28 ℃), specific heat of water appearance is greater than air simultaneously, and radiating effect is better.
3, heat energy utilization is abundant.General equipment is heating up to wind, when reducing relative humidity, directly utilizes electrical heating, and the heat that refrigeration system compressor produces is not utilized, and has wasted.The utility model utilizes the first condenser intensification for wind by the heat recovery of compressor generation of refrigeration system, is conducive to reduce the relative humidity of casing air-out.
Below in conjunction with accompanying drawing, further illustrate the technical solution of the utility model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the double-refrigerant integral type grain cooling machine that the utility model provides, comprises ventilation unit, the cooling system of underground water and refrigeration system; Described ventilation unit comprise establish air inlet 7 and air outlet 12 casing 13, be located at the blower fan 11 on air outlet 12, the air inlet 7 of casing 13 is provided with screen pack 16; The cooling system of described underground water comprises water pump 6, heat exchanger 8 and water tank 2, water pump 6 is located in the ground in well and is connected with heat exchanger 8 by water pipe 5, heat exchanger 8 is located at the water inlet pipe 4 that passes through water tank 2 in the interior air inlet of described casing 13 7 places and is connected with water tank 2, and water tank 2 is received underground water well by outlet pipe 1; Described refrigeration system comprises compressor 10, the evaporimeter 9 and the condenser that are connected with compressor 10, after described evaporimeter 9 is located at and is positioned at heat exchanger 8 in described casing 13, described condenser comprises the first condenser 14 and the second condenser 3 being connected with the first condenser 14, between the second condenser 3 and evaporimeter 9, be provided with flow controller 17, after described the first condenser 14 is located at and is positioned at evaporimeter 9 in described casing 13, described the second condenser 3 is located in described water tank 2, in described casing 13 with the corresponding cooling fan 15 that is provided with of described the first condenser 14; After being positioned at the first condenser 14 in casing 13, locate to be provided with humiture detector 18, humiture detector 18 is connected with automatic control system with cooling fan 15.
Operation principle of the present utility model:
It is rear first by screen pack 16 removal of impurities that outside air enters this box body 13, by heat exchanger 8, carry out precooling again, then pass through evaporimeter 9 cooling and dehumidifyings, through the first condenser 14 heat temperature raisings, reduce the relative humidity of air, finally by blower fan 11, discharge and send into silo for low-temperature grain-storage.Groundwater use water pump 6 is extracted out from underground water intake well 20, first by heat exchanger 8, carries out cold and hot exchange, then enters water tank 2 for the first condenser 3 heat radiations, then is entered in underground back water well 19 by outlet pipe 1.
It is to consider that the wind of sending into silo reduces the heat that the needed heat of relative humidity is generally less than compressor generation, utilizes the second condenser 3 unnecessary heat can be drawn to the outer heat radiation of casing 13 that refrigeration system arranges two condensers.
As run into, need the wind that humidity is lower, when the heat providing when the first condenser 14 can not meet the demand that reduces relative humidity, can to wind, heat at the interior auxiliary electro-heat device of separately establishing of casing 13.
Automatic control system is adjusted the rotating speed of cooling fan 15 automatically by humiture detector 18 feedacks, thereby control, spill into the heat in wind, controls the relative humidity of wind.
Heat exchanger 8 utilizes underground water cold energy, the water yield fully, exchange face enough can guarantee that wind is after over-heat-exchanger greatly time, wind-warm syndrome is constant.
The utility model can made portable equipment in concrete application, can flow like this and provide low-temperature grain-storage operation for grain depot.
