Description
Technical field
The present invention relates to logistics cold chain transportation device field, specifically a kind of Cold Chain Logistics are controlled with haulage truck temperature is
System.
Background technique
Logistics cold chain transportation, which refers to, transports food etc. to market from the place of production, and Keep cool during transportation makes it not
A rotten process, as the improvement of people's living standards, huge change also has occurred in the user structure of cold chain Yuan's art, transport
Food is gradually from frozen food develops to fresh meat, water fruits and vegetables account for increasing ratio.And temperature control is to protect in transportational process
The basic assurance of fresh chilled food, traditional cold chain transportation make food not corrupt only by low temperature, but are not able to maintain fresh
The freshness of food is not able to satisfy requirement of the consumer to cold chain transportation food quality；And existing cold chain vehicle refrigeration equipment
Complexity can not achieve the separation of compartment and refrigeration equipment.
Summary of the invention
It is an object of the present invention to provide a kind of Cold Chain Logistics haulage truck temperature control systems, to solve to deposit in the prior art
Defect.
The technical scheme to solve the above technical problems is that
A kind of Cold Chain Logistics haulage truck temperature control system, including liquid nitrogen hutch (1), the liquid nitrogen hutch
(1) it is provided on exhaust pipe solenoid valve (6), the solenoid valve (6) is by controller (5) control switch, and the controller (5) is even
Jointing temp sensor (9), and by set temperature compared with temperature sensor (9), to control the switch of solenoid valve (6), liquid nitrogen
Liquid nitrogen in hutch (1) carries out cooling refrigeration by liquid nitrogen spray being gone out by injection apparatus (8) after solenoid valve (6)；
Further, the liquid nitrogen hutch (1) is provided with liquid feeding nitrogen valve (4), for supplementing liquid nitrogen；
Further, exhaust outlet (2) are also connected by pipeline on the liquid nitrogen hutch (1), official is provided with pressure on road
Table and safety valve (3), pressure gauge are connect with the controller (5), when pressure is more than setting value, controller (5) control safety
Valve (3) is opened, and liquid nitrogen is discharged from exhaust outlet (2), is prevented liquid nitrogen hutch (1) pressure excessive, is caused danger；
Further, corrugated nozzle (7) are provided between the solenoid valve (6) and injection apparatus (8), are used for buffering pipe
Pressure reduces the waste of liquid nitrogen.
The beneficial effects of the present invention are: being opened according to the temperature that temperature sensor measures solenoid valve by controller
It closes, temperature in compartment can be adjusted automatically, and the gas after liquid nitrogen refrigerating agent evaporation can keep the new of fresh food
It is fresh, improve transport quality；Entire temperature control system structure is simple, can flexibly move, and is easily installed in any cold chain fortune
On defeated vehicle.

Specific embodiment
The present invention is described in detail With reference to embodiment.
As shown in Figure 1, a kind of Cold Chain Logistics haulage truck temperature control system, including liquid nitrogen hutch (1), the liquid
It is provided with solenoid valve (6) on nitrogen hutch (1) exhaust pipe, the solenoid valve (6) is by controller (5) control switch, the control
Device (5) processed connects temperature sensor (9), and by set temperature compared with temperature sensor (9), to control solenoid valve (6)
It switchs, the liquid nitrogen in liquid nitrogen hutch (1) is carried out by liquid nitrogen spray being gone out by injection apparatus (8) after solenoid valve (6)
Cooling refrigeration；
Further, the liquid nitrogen hutch (1) is provided with liquid feeding nitrogen valve (4), for supplementing liquid nitrogen；
Further, exhaust outlet (2) are also connected by pipeline on the liquid nitrogen hutch (1), official is provided with pressure on road
Table and safety valve (3), pressure gauge are connect with the controller (5), when pressure is more than setting value, controller (5) control safety
Valve (3) is opened, and liquid nitrogen is discharged from exhaust outlet (2), is prevented liquid nitrogen hutch (1) pressure excessive, is caused danger；
Further, corrugated nozzle (7) are provided between the solenoid valve (6) and injection apparatus (8), are used for buffering pipe
Pressure reduces the waste of liquid nitrogen.
In use, controller is compared according to the temperature that temperature sensor perceives with setting value, when temperature is higher than setting
When value, control solenoid valve is opened, and liquid nitrogen is sprayed from injection apparatus, and to carrying out refrigeration cool-down in compartment, while nitrogen can be to vehicle
Fresh food progress in compartment is fresh-keeping, and when temperature reaches setting value, solenoid valve is closed, and stops cooling.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
