Accompanying drawing explanation
Figure 1 shows that the structural representation of the utility model jacket type liquid nitrogen spraying refrigerating box.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model jacket type liquid nitrogen spraying refrigerating box, comprises casing 1, and described casing 1 top is separated out chuck layer by dividing plate 3, and described dividing plate 3 is provided with multiple exhaust vent.In described chuck layer, liquid nitrogen spraying device is installed.Described liquid nitrogen spraying device is connected with fluid reservoir 10 by water influent pipeline, described water influent pipeline is provided with spray control valve 8 and pressure charging valve 9.In described chuck layer, breeze fan 2 is installed, in described chuck layer, is provided with the air intake control valve 6 be in communication with the outside, bottom described casing 1, be provided with gas exhausting valve 13.Fruit and vegetable storage and transportation district in described casing 1 is provided with oxygen concentration checkout gear 11, temperature-detecting device 12 and pressure-detecting device.Described oxygen concentration checkout gear 11, temperature-detecting device 12, pressure-detecting device, spray control valve 8, air intake control valve 6 are connected with controller 7 respectively with gas exhausting valve 13.When the temperature value that described temperature-detecting device 12 detects is more than or equal to setting value, then detect oxygen density value, if when the oxygen concentration that oxygen concentration checkout gear 11 is monitored is more than or equal to setting value, then controller 7 control spray control valve 8 pairs of box houses fill nitrogen, if when the oxygen concentration that oxygen concentration checkout gear 11 is monitored is less than setting value, then open air intake control valve 6 while opening spray control valve 8.When the temperature value that temperature-detecting device 12 is monitored is less than or equal to setting value, then close spray control valve 8, stop filling nitrogen.If when the pressure-detecting device pressure monitored in fruit and vegetable storage and transportation district is greater than atmospheric pressure, then opens gas exhausting valve 13 and be vented.
In the present embodiment, described spray equipment comprises and is installed on liquid nitrogen pipeline 4 in described chuck layer and multiple atomizer 5, and the liquid nitrogen that described atomizer 5 sprays is by the fruit and vegetable storage and transportation district in the effect feeding casing of described breeze fan 2.In order to make the uniform temperature fields in casing, unlikely being dropped on fruits and vegetables of liquid nitrogen drop forms frostbite, and described liquid nitrogen pipeline all needs to superscribe insulation material.The preferred hollow tapered atomizer of described atomizer.
In the present embodiment, described oxygen concentration checkout gear 11 is oxygen concentration sensor; Described temperature-detecting device 12 is temperature sensor; Described pressure-detecting device is pressure sensor.
Liquid nitrogen atomized drop is after nozzle ejection, and by can compared with the jacket type air supply mode of balanced ventilation, that is not only blown by the liquid nitrogen drop of comparatively dense be comparatively uniformly dispersed, and partial drop is vaporized.By the mode of jacket type air-supply, liquid nitrogen spraying is blown, solve the problem that temperature field in casing is uneven, and avoid the frostbite of low temperature liquid nitrogen drop to fruits and vegetables.
When the temperature value of the temperature sensor monitors in fruit and vegetable storage and transportation district is higher than setting value, the oxygen density value of oxygen concentration sensor monitoring is more than or equal to setting value, then controller controls spray control valve fluid; If the oxygen density value of oxygen concentration sensor monitoring is less than setting value, then open air intake control valve while opening spray control valve.If the temperature value that temperature sensor detects is less than or equal to setting value, then close spray control valve, stop filling nitrogen; If the temperature value that temperature sensor detects is more than or equal to setting value, then detect oxygen density value.If the temperature value of temperature sensor monitors is less than or equal to setting value, then stop filling nitrogen.If the pressure in fruit and vegetable storage and transportation district is greater than atmospheric pressure, then open gas exhaust inspecting valve exhaust.So go round and begin again.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
