Description

Technical Field

[0001] The utility model relates to the technical field of storage tanks, in particular to a sediment-proof fresh milk storage tank. Background Technique

[0002] When fresh milk is transported from the ranch to the processing plant, it will not be directly sent to the production line, but needs to be initially inspected and then temporarily stored in a fresh milk storage tank. The temporary storage time generally does not exceed 24 hours. After the production line is debugged, the fresh milk will be transported from the storage tank to the pasteurization workshop of the production line for the first process of processing.

[0003] At present, most of the common vertical fresh milk storage tanks for storing fresh milk are inner tanks with ordinary tank structures, and an insulating tank for refrigeration, heating, and heat preservation is arranged outside to ensure that fresh milk can be stored under suitable temperature conditions throughout the year with different temperatures. To ensure sufficient storage capacity, the volume of vertical fresh milk storage tanks is generally relatively large, such as the common 10 tons, 20 tons, 30 tons, etc. In fresh and healthy fresh milk, due to the rich content of nutrients such as fat and protein, it is easy to aggregate and form sediment. When discharging from the fresh milk storage tank, if the sediment of nutrients such as fat and protein does not discharge with the fresh milk, on the one hand, it will cause the loss of nutrients such as fat and protein during the cleaning of the fresh milk storage tank, and on the other hand, it will also cause a decrease in the content of nutrients such as fat and protein in the fresh milk transported to the production line.

[0004] However, due to the limitation of the physical factors of the pipeline welding of the fresh milk storage tank, it is difficult to connect the milk delivery pipe to the bottom of the inner wall of the storage tank. Therefore, when discharging fresh milk, it is easy to occur the phenomenon that part of the sediment of nutrients such as fat and protein does not discharge, resulting in a large amount of waste. Therefore, a fresh milk storage tank that can prevent fresh milk from sedimenting and smoothly discharge the sediment of nutrients such as fat and protein is designed and proposed. Content of the Utility Model

[0005] Aiming at the deficiencies existing in the prior art, the utility model provides a sediment-proof fresh milk storage tank, which is used to solve the problem that part of the sediment of nutrients such as fat and protein is not discharged easily when discharging fresh milk from the existing vertical fresh milk storage tank.

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] A sediment-proof fresh milk storage tank includes an inner tank, a milk inlet pipe, a milk delivery pipe, and an insulating tank arranged outside the inner tank. The milk inlet pipe penetrates through the insulating tank and is connected to the inner tank. The milk delivery pipe is connected with a straight discharge pipe and multiple flow-promoting pipes through a multi-way confluence pipe. The straight discharge pipe and the multiple flow-promoting pipes are in the same horizontal plane and parallel to each other. The straight discharge pipe, the flow-promoting pipes, and the milk inlet pipe all penetrate through the insulating tank and are installed at a position close to the bottom of the outer wall of the inner tank, and one end of the straight discharge pipe penetrates through the inner tank and extends to the central position inside the inner tank;

[0008] The milk inlet pipe and the direct discharge pipe are located on the same diameter of the inner tank. The flow promoting pipes and the direct discharge pipe are arranged on the same side of the inner tank, and one of the flow promoting pipes far from the direct discharge pipe is located on the tangent line of the inner wall of the inner tank parallel to the direct discharge pipe. The distance between adjacent flow promoting pipes is equal, and the arrangement width of the flow promoting pipes does not exceed one-half of the radius of the inner tank.

[0009] Preferably, stop valves are installed on both the milk inlet pipe and the milk delivery pipe.

[0010] Preferably, the end of the direct discharge pipe located inside the inner tank is provided with an elbow that bends downward and is close to the bottom of the inner wall of the inner tank.

[0011] Preferably, throttle valves and flow meters are installed at one ends of the direct discharge pipe and the flow promoting pipes close to the multi-way confluence pipe.

[0012] Preferably, the flow meter is installed between the throttle valve and the multi-way confluence pipe.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] By arranging a plurality of flow promoting pipes arranged side by side, and the outermost flow promoting pipe is parallel to the tangent line of the inner wall of the inner tank, and the milk inlet end of the direct discharge pipe has a downward-bending elbow, when discharging fresh milk, the opening degree can be adjusted through the throttle valve to adjust the flow rate of the direct discharge pipe and each flow promoting pipe, so that most of the fresh milk is discharged from the flow promoting pipes close to the inner wall of the inner tank, promoting the fresh milk to flow inside the inner tank to form a vortex, and under the action of centrifugal force, promoting the precipitation and collection of nutrients such as fat and protein to the center inside the inner tank and being extracted and output by the elbow and the direct discharge pipe, thereby preventing the waste caused by the precipitation of nutrients such as fat and protein not being discharged, and solving the problem that when discharging fresh milk from the existing vertical fresh milk storage tank, it is easy to have some nutrients such as fat and protein not being discharged.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1-4 shown, the present invention provides a technical solution: an anti-sediment fresh milk storage tank, including an inner tank 1, a milk inlet pipe 2, a milk delivery pipe 3, and a thermal insulation tank 4 arranged outside the inner tank 1. Stop valves 8 are installed on both the milk inlet pipe 2 and the milk delivery pipe 3. The milk inlet pipe 2 penetrates through the thermal insulation tank 4 and is connected to the inner tank 1. The milk delivery pipe 3 is connected with a direct discharge pipe 6 and multiple flow-promoting pipes 7 through a multi-way manifold pipe 5;

[0022] The direct discharge pipe 6 and the multiple flow-promoting pipes 7 are in the same horizontal plane and are parallel to each other. The direct discharge pipe 6, the flow-promoting pipes 7, and the milk inlet pipe 2 all penetrate through the thermal insulation tank 4 and are installed at positions close to the bottom of the outer wall of the inner tank 1. One end of the direct discharge pipe 6 penetrates through the inner tank 1 and extends to the central position inside the inner tank 1. The end of the direct discharge pipe 6 located inside the inner tank 1 is provided with an elbow 9 that bends downward and is close to the bottom of the inner wall of the inner tank 1;

[0023] The milk inlet pipe 2 and the direct discharge pipe 6 are on the same diameter of the inner tank 1. The flow-promoting pipes 7 and the direct discharge pipe 6 are arranged on the same side of the inner tank 1. And one of the flow-promoting pipes 7 far from the direct discharge pipe 6 is located on the tangent line of the inner wall of the inner tank 1 parallel to the direct discharge pipe 6. The distance between adjacent two flow-promoting pipes 7 is equal, and the arrangement width of the flow-promoting pipes 7 does not exceed half of the radius of the inner tank 1;

[0024] Throttle valves 10 and flowmeters 11 are installed at one end of the direct discharge pipe 6 and the flow-promoting pipes 7 close to the multi-way manifold pipe 5. The flowmeters 11 are installed between the throttle valves 10 and the multi-way manifold pipe 5.

[0025] Working principle: When discharging fresh milk, the opening degree can be adjusted through the throttle valve 10 to adjust the flow rate of the direct discharge pipe 6 and each flow-promoting pipe 7, so that most of the fresh milk is discharged from the flow-promoting pipes 7 near the inner wall of the inner tank 1, prompting the fresh milk to flow inside the inner tank 1 to form a vortex. Under the action of centrifugal force, it prompts nutrients such as fat and protein to precipitate and gather in the center inside the inner tank 1 and be extracted and output by the elbow 9 and the direct discharge pipe 6, thus preventing the waste caused by the precipitation of nutrients such as fat and protein not being discharged.
