Description

Technical Field

[0001] This utility model relates to the field of refrigerated transportation technology, and more specifically, to a fresh milk refrigerated transportation device. Background Technology

[0002] Dairy products are rich in fat, protein, carbohydrates, and minerals, and have high nutritional value. To prevent fresh milk from spoiling at room temperature, it needs to be stored at low temperatures in refrigerated tanks. The "Regulations on the Management of Raw Milk Production and Acquisition" stipulate that after milking, raw milk should be stored in sealed containers and cooled down in time to keep its temperature between 0 and 4°C. Milk that has not been refrigerated for more than 2 hours shall not be sold. Therefore, refrigerated transportation is required for milk transportation.

[0003] Patent document CN222611687U discloses a milk transport container. It includes a ring, a container body, and a connecting rod. A support base is provided on the lower surface of the container body, and the ring is fitted onto the outer wall of the container body. Connecting heads are symmetrically and rotatably mounted at both ends of the connecting rod, and the connecting heads are threaded onto the ring. This invention uses the cooperation between the structures to form a whole from the individual containers, thereby avoiding collisions between the milk transport containers and the tendency for the milk transport containers to tip over. In the above technical solution, the opening of the milk transport container is located at the top of the container, and the container cannot be tilted, making it inconvenient to pour milk out.

[0004] Therefore, it is necessary to propose a fresh milk refrigerated transport device to solve the problems existing in the prior art. Utility Model Content

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0030] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0031] like Figures 1-8 As shown, a fresh milk refrigerated transport device includes a transport tank 1 and a frame 2. The transport tank 1 is mounted on the frame 2, and the rear end of the transport tank 1 is hinged to the rear end of the frame 2. The front part of the frame 2 is provided with a lifting component for lifting the front end of the transport tank 1.

[0032] Furthermore, the lifting assembly includes a base 3 fixedly mounted on the frame 2, a groove 4 is formed on the upper surface of the base 3, a lifting airbag 5 is fixedly mounted on the bottom surface of the groove 4, and an air pipe through an air pipe hole 6 is formed on the side wall of the groove 4.

[0033] Furthermore, the upper surface of the base 3 is on the same horizontal plane as the upper surface of the frame 2, and two bases 3 are arranged side by side.

[0034] Furthermore, the transport tank 1 includes an inner liner 101, a heat insulation layer 102, and a protective layer 103 that are fixedly connected from the inside to the outside. The bottom of the transport tank 1 is flat. A cooling pipe 104 is provided between the inner liner 101 and the heat insulation layer 102 at the bottom of the transport tank 1. The cooling pipe 104 is tightly fixedly connected to the inner liner 101.

[0035] Furthermore, horizontal reinforcing beams 7 are fixedly installed at the front and rear ends of the bottom surface of the transport tank 1, and a longitudinal reinforcing beam 8 is fixedly installed between the two horizontal reinforcing beams 7 on the bottom surface of the transport tank 1. The longitudinal reinforcing beam 8 is fixedly connected to the horizontal reinforcing beams 7.

[0036] Furthermore, a first hinge seat 9 is fixedly installed on the lower end surface of the rear transverse reinforcing beam 7, and a second hinge seat 10 is fixedly installed at the rear of the frame 2 at a position corresponding to the first hinge seat 9. The second hinge seat 10 is hinged to the first hinge seat 9 through a hinge shaft 11.

[0037] Furthermore, the inner liner 101 is made of food-grade aluminum alloy material;

[0038] The thickness of the inner liner 101 is 3mm.

[0039] Furthermore, the heat insulation layer 102 is made of polyurethane material, and the protective layer 103 is made of stainless steel material.

[0040] Furthermore, several partitions 14 are provided inside the transport tank 1, and a channel is left between the lower edge of the partition 14 and the bottom surface of the transport tank 1. Through holes 15 are opened on the partition 14.

[0041] Furthermore, the frame 2 is a truck frame or a semi-trailer frame.

[0042] The working principle of the above technical solution:

[0043] Fresh milk produced by dairy farms or dairy farmers needs to be cooled down in time and transported to milk processing plants for processing. Since it is impossible for all dairy farms or dairy farmers to be concentrated near milk processing plants, the fresh milk produced needs to be cooled down in time and transported to milk processing plants in time after reaching the temperature required for fresh milk preservation.

[0044] After each use, the fresh milk transport device must be cleaned to prevent the residual fresh milk in the tank from spoiling or bacteria from growing. In addition, to improve the efficiency of the fresh milk transport device, it can also be used to transport alcoholic beverages, cooking oil, or fruit juice. The transport tank should be cleaned in time after each use for the next use.

[0045] Some large milk processing plants have milk pumps at their unloading stations, which pump milk from transport tanks through pumps and pipelines. Some processing plants do not have milk pumps and can only release milk through the milk outlet. Regardless of whether a milk pump is used or the milk flows out through its own weight, the end of the transport tank furthest from the milk outlet cannot be raised to a certain height, which will result in the milk not being completely released.

[0046] The transport tank 1 is mounted on the frame 2, with its rear end hinged to the rear of the frame 2. A lifting assembly for lifting the front end of the transport tank 1 is located at the front of the frame 2. The lifting assembly, located away from the milk outlet 17, includes a base 3 fixedly mounted on the frame 2. A groove 4 is formed on the upper surface of the base 3, and a lifting airbag 5 is fixedly mounted on the bottom surface of the groove 4. During milk dispensing, the lifting airbag 5 is inflated using an air tank on the truck, raising the front end of the transport tank 1 to a certain height, allowing the milk inside the transport tank 1 to flow outwards. The milk outlet 17 allows for the complete drainage of milk from the transport tank. A milk inlet 18 is located on the rear side wall of the transport tank 1, allowing fresh milk to be pumped into the transport tank 1. Both the milk outlet 17 and the milk inlet 18 are equipped with valves. To prevent contamination of the milk inlet 18 during transport, a sealed box can be installed on the rear wall of the transport tank 1 to seal the milk outlet 17 and the milk inlet 18. When milk needs to be dispensed or discharged, the door of the sealed box is opened, and after dispensing or dispensing, the door is closed, thus protecting the milk outlet 17 and the milk inlet 18.

[0047] An air pipe is provided on the side wall of the groove 4, passing through an air pipe hole 6. The air pipe is connected to the air inlet of the lifting airbag 5 through the air pipe hole 6. The other end of the air pipe is connected to the air cylinder of the truck to inflate the lifting airbag. The air pipe hole 6 is provided so that after the transport tank 1 is lowered, the cross reinforcement beam 7 will directly contact the frame and will not press on the air pipe to prevent damage. The lifting airbag 5 also includes a pressure sensor and control device. The lifting airbag is existing technology, and an airbag with a pressure matching the capacity of the transport tank 1 can be selected from the market. It will not be described in detail here. The groove 4 on the base 3 is used to accommodate the deflated lifting airbag 5. A locking component can also be provided between the lower end face of the front cross reinforcement beam 7 and the frame 2 at a position spaced from the lifting component. During transportation, the transport tank 1 is locked to the frame to ensure the stability of the transport tank during transportation. The locking component is existing technology, such as the locking mechanism of the dump truck box disclosed in CN118906946A. It will not be described in detail here.

[0048] Because air brakes have high braking force, fast response speed, simple structure and high safety, most existing heavy-duty trucks use air brakes. The trucks are equipped with high-pressure air tanks, and the front end of the transport tank is lifted by the high-pressure air tank and lifting airbag. The structure is simple, the cost is low and it is easy to operate.

[0049] The transport tank 1 includes an inner liner 101, a heat insulation layer 102, and a protective layer 103, which are fixedly connected from the inside to the outside. The bottom of the transport tank 1 is flat. A cooling pipe 104 is provided between the inner liner 101 and the heat insulation layer 102 at the bottom of the transport tank 1. The cooling pipe 104 is tightly fixedly connected to the inner liner 101. The cooling pipe 104 passes through the side wall at the front end of the transport tank and is connected to a refrigeration compressor 16 fixedly installed at the upper front end of the frame 2. The cooling pipe 104 is connected to the refrigeration compressor 16 through a hose.

[0050] The inner liner 101 can be made of food-grade aluminum alloy. Food-grade aluminum alloy can meet the requirements for transporting food. It is lightweight and has high strength, making it a high-quality material for making the inner liner of transport tanks. The thickness of the inner liner 101 can be selected as 3mm.

[0051] The insulation layer 102 is made of polyurethane material, and the protective layer 103 is made of stainless steel material. Several baffles 14 are installed inside the transport tank 1 to prevent the milk inside the transport tank from shaking due to emergency braking of the transport device during operation. The channel between the lower edge of the baffle 14 and the bottom surface of the transport tank 1 and the through holes 15 on the baffle 14 allow the milk to flow between the baffles. The through holes 15 can be set with multiple different diameters.

[0052] By placing the cooling pipe 104 at the bottom of the transport tank 1, the number of cooling pipes 104 can be reduced and the cooling effect can be improved. During transportation, the milk in the transport tank 1 will shake during the vehicle's operation, starting, or braking. This can keep the temperature of each layer of milk in the transport tank 1 the same. A stirring device can also be installed in the transport tank 1 to stir the milk in the transport tank 1, so that the milk added to the transport tank 1 can be cooled evenly. This can be used when the produced milk is added to the transport tank 1 without being cooled.

[0053] The longitudinal reinforcing beam 8 and the transverse reinforcing beam 7 can improve the bottom strength of the transport tank 1. The partition 14 fixedly installed inside the transport tank 1 can improve the overall strength of the transport tank. The lifting airbag 5 of the lifting assembly is located below the transverse reinforcing beam 7 at the front end of the transport tank 1. When lifting the transport tank 1, the lifting airbag 5 rests on the lower part of the transverse reinforcing beam 7 at the front end to prevent the transport tank 1 from deforming. Two bases 3 are arranged side by side along the width direction of the frame 2. When lifting the transport tank 1, the two lifting airbags 5 work at the same time to improve the stability during lifting.

[0054] The frame 2 can be a truck frame or a semi-trailer frame. The truck frame or semi-trailer frame is mounted on the chassis and can be used for dedicated milk transportation. Alternatively, the frame 2 can be mounted on the cargo box of a transport vehicle, depending on the size of the transport tank.

[0055] The beneficial effects of the above technical solution are as follows:

[0056] The fresh milk refrigerated transport device of this utility model has a transport tank mounted on a vehicle frame. The rear end of the transport tank is hinged to the rear end of the vehicle frame. The front of the vehicle frame is equipped with a lifting component for lifting the front end of the transport tank. After the milk is transported to the destination, the lifting component lifts the front end of the transport tank, which facilitates the release of milk from the transport tank and improves unloading efficiency.
