Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of semi-trailers, and particularly relates to a milk tank with a refrigeration function and a milk transportation semi-trailer. Background Art
[0002] In the existing ranch milk production, generally, the milk squeezed out by dairy cows is collected in large quantities and then filled into a milk tanker for transportation. However, a new milk filling method has emerged, which is to guide the milk squeezed out by dairy cows into a trickle pipe while milking, and the trickle pipe then guides the milk into a heat exchanger for cooling, and then fills it into the milk tank. This milk filling method takes a long time, usually more than 10 hours to fill the milk tank. Since the filling time of the milk is long and the temperature of the milk passing through the heat exchanger may not necessarily be maintained at about 2°C, the milk in the milk tank still needs to be refrigerated continuously.
[0003] In addition, the production areas of milk are relatively concentrated. In order to transport the milk to places outside the production areas, it is necessary to use a milk tanker to transport it. However, the transportation distance is long, and in hot weather, the insulation function of the milk tank itself cannot ensure that the temperature of the delivered milk meets the acceptance requirements, which may cause the milk to deteriorate, not only resulting in economic losses but also posing potential food safety hazards. Therefore, a milk transportation semi-trailer that can ensure the milk temperature meets the acceptance requirements after long-distance transportation in hot weather is needed. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a milk tank with a refrigeration function and a milk transportation semi-trailer, which are used to solve the technical problems in the prior art that the milk tank cannot control the temperature for the long-time filling method of trickle filling milk, maintain the milk in the milk tank at a constant temperature, and the milk transportation semi-trailer cannot control the milk temperature within the acceptance requirements after long-distance transportation in hot weather.
[0005] The technical solution of the utility model to solve the above technical problems is as follows: A milk tank with a refrigeration function includes:
[0006] A heat preservation interlayer is provided on the outer wall of the tank body of the milk tank;
[0007] A refrigeration pipeline, the refrigeration pipeline is arranged in the heat preservation interlayer, and the refrigeration pipeline is attached to the outer wall of the tank body of the milk tank;
[0008] The refrigeration pipeline includes several groups of U-shaped circulation pipes, several groups of the U-shaped circulation pipes are welded on the outer wall of the tank body of the milk tank in a circumferential and evenly distributed manner, and the two ends of each U-shaped circulation pipe are respectively communicated with a refrigeration inlet pipe and a refrigeration outlet pipe;
[0009] The refrigeration inlet pipe and the refrigeration outlet pipe extend out of the heat preservation interlayer.
[0010] In the utility model, a refrigeration pipeline is arranged in the heat preservation interlayer of the milk tank. The refrigeration pipeline contacts with the outer wall of the milk tank, and then a refrigeration working medium can be injected into the refrigeration pipeline, so as to realize the refrigeration of the milk tank, and then heat transfer is carried out to achieve the purpose of controlling the temperature of the milk in the milk tank. Among them, several groups of U-shaped circulation pipes can contact with the milk tank in a large range and can refrigerate the milk tank evenly.
[0011] Furthermore: Two stirrers are also arranged at the bottom of the milk tank, and the two stirrers are arranged at the front and rear of the milk tank.
[0012] Beneficial effect of this step: The stirrers can work simultaneously when the refrigerating machine is running, preventing the milk in the milk tank from precipitating and crystallizing after long-term stillness and refrigeration.
[0013] Furthermore: A liquid level gauge is arranged at the top of the milk tank.
[0014] Beneficial effect of this step: The liquid level gauge can monitor the filling amount of the milk in the milk tank, preventing overfilling when injecting milk into the milk tank.
[0015] Furthermore: The liquid level gauge is also provided with a temperature sensor.
[0016] Beneficial effect of this step: The temperature sensor can detect the temperature of the milk in the milk tank, and then decide whether to start the refrigerating machine based on this temperature; in this way, it is not necessary to start the refrigerating machine throughout the process, and it is possible to choose whether to start the refrigerating machine according to the actual situation, so as to achieve the purpose of saving energy.
[0017] Furthermore: The cross-section of the U-shaped circulation pipe is flat tubular.
[0018] Beneficial effect of this step: The flat tubular U-shaped circulation pipe can have a larger contact area with the outer wall of the milk tank, improving the heat exchange efficiency.
[0019] The utility model also provides a semi-trailer for transporting milk, including:
[0020] A milk tank with a refrigeration function as described above, and the milk tank is arranged on the semi-trailer;
[0021] A refrigerating machine, which is arranged on the semi-trailer and is communicated with the refrigeration pipeline.
[0022] The refrigerating machine can move along with the semi-trailer, and can refrigerate the milk tank at any time during the transportation process to resist the adverse effects of the environmental temperature and time on the milk temperature during long-distance transportation in hot weather.
[0023] Furthermore: The refrigerating machine is a liquid-cooled refrigerating machine or a compression refrigerating machine.

[0025] The beneficial effects of the present utility model are as follows:
[0026] 1. The existing milk tank refrigeration method is to directly blow the cold air generated by the air conditioner into the tank, and the cold air directly contacts the milk, which may cause the number of certain colonies in the milk to exceed the standard and affect the milk quality. However, the refrigeration method of this application isolates the working medium from the milk and allows the working medium to cool the milk through heat transfer to ensure the safety of the milk.
[0027] 2. It can not only keep the temperature of the milk meeting the requirements during transportation, but also timely control the temperature of the milk entering the tank when the milk is filled into the tank, avoiding the impact on the milk quality caused by the long filling process.

[0039] Embodiment
[0040] As Figure 1 shown, a milk can with a refrigeration function provided by the present utility model includes:
[0041] A heat insulation layer 2 is provided on the outer wall of the can body of the milk can 1;
[0042] A refrigeration pipeline 3, the refrigeration pipeline 3 is arranged in the heat insulation layer 2, and the refrigeration pipeline 3 is attached to the outer wall of the milk can 1;
[0043] The refrigeration pipeline 3 includes several groups of U-shaped circulation pipes. The several groups of U-shaped circulation pipes are welded on the outer wall of the tank body of the milk tank 1 in a circular and evenly distributed manner with the body of the milk tank 1 as the central axis. The two ends of each U-shaped circulation pipe are respectively connected to the refrigeration inlet pipe 7 and the refrigeration outlet pipe 8. Outside the several groups of U-shaped circulation pipes, a plurality of tank body reinforcing rings 31 are also sleeved.
[0044] The refrigeration inlet pipe 7 and the refrigeration outlet pipe 8 extend out of the heat preservation interlayer 2. The refrigeration inlet pipe 7 and the refrigeration outlet pipe 8 can be externally connected to a refrigeration device, so that the working medium of the refrigeration device circulates in the refrigeration pipeline 3.
[0045] In the present utility model, a refrigeration pipeline 3 is arranged in the heat preservation interlayer 2 of the milk tank 1. By contacting the outer wall of the tank body of the milk tank 1, and then injecting a refrigeration working medium into the refrigeration pipeline 3, the milk tank 1 can be refrigerated, and then heat transfer can be carried out to achieve the purpose of controlling the temperature of the milk in the milk tank 1. Among them, several groups of U-shaped circulation pipes can have a large range of contact with the milk tank 1 and can refrigerate the milk tank 1 evenly.
[0046] On the basis of the above technical solution, two stirrers 5 are further arranged at the bottom of the milk tank 1, and the two stirrers 5 are arranged at the front and rear of the milk tank 1.
[0047] The stirrers 5 can work simultaneously when the refrigerating machine 6 is running, preventing the milk in the milk tank 1 from precipitating and crystallizing after long-term stillness and refrigeration (referring to when the milk is trickle-filled).
[0048] On the basis of the above technical solution, a liquid level gauge 4 is arranged at the top of the milk tank 1.
[0049] The liquid level gauge 4 can monitor the filling amount of the milk in the milk tank 1 and prevent overfilling when injecting milk into the milk tank 1.
[0050] On the basis of the above technical solution, the liquid level gauge 4 is further provided with a temperature sensor.
[0051] The temperature sensor can detect the temperature of the milk in the milk tank 1, and then decide whether to start the refrigerating machine 6 based on this temperature; in this way, it is not necessary to start the refrigerating machine 6 throughout the process, and it is possible to choose whether to start the refrigerating machine 6 according to the actual situation to achieve the purpose of saving energy.
[0052] On the basis of the above technical solution, the cross-section of the U-shaped circulation pipe is flat tubular.
[0053] The flat tubular U-shaped circulation pipe can have a larger contact area with the outer wall of the tank body of the milk tank 1, improving the heat exchange efficiency.
[0054] The present utility model also provides a milk transportation semi-trailer, including:
[0055] The milk tank 1 with a refrigeration function as described above is provided on a semi-trailer truck;
[0056] A refrigerating machine 6 is provided on the semi-trailer truck, and the refrigerating machine 6 is communicated with the refrigeration pipeline 3.
[0057] The refrigerating machine 6 can move along with the semi-trailer truck, and the milk tank 1 can be refrigerated at any time during transportation to resist the adverse effects of environmental temperature and time on the milk temperature during long-distance transportation in high-temperature weather.
[0058] On the basis of the above technical solution, the refrigerating machine 6 is a liquid-cooled refrigerating machine or a compression refrigerating machine.
[0059] Generally, refrigeration equipment includes direct refrigeration and indirect refrigeration. The common feature of the two is that they both have a compressor. The compressor compresses the refrigerant and sends it into the condenser, then into the expansion valve, and finally into the evaporator to achieve refrigeration through the evaporator. The liquid-cooled refrigerating machine sends the working medium into the evaporator, allows the working medium to be affected by the refrigerant in the evaporator to reduce the temperature of the working medium, and then sends the working medium into the refrigeration pipeline 3, which belongs to indirect refrigeration. The compression refrigerating machine uses the refrigeration pipeline 3 as an evaporator, directly sends the refrigerant into the refrigeration pipeline 3, and allows the refrigerant to absorb heat and vaporize in the refrigeration pipeline 3 to achieve the refrigeration purpose, which belongs to direct refrigeration. In addition, the working medium of the liquid-cooled refrigerating machine is generally a liquid with a relatively large specific heat capacity such as water, oil or ethylene glycol, and needs to be used in cooperation with a pump body. Under the action of the internal compressor of the compression refrigerating machine, the refrigerant can flow in the refrigeration pipeline 3 without a pump body.
[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
