Description

Technical Field

[0001] This utility model relates to the field of food equipment technology, specifically to a self-priming pump interface device for collecting milk. Background Technology

[0002] In some large dairy farms, milkers collect the milk from the cows and store it in storage tanks. They then perform high-temperature sterilization and other processes before transporting it to processing plants via milk trucks for further processing into various dairy products.

[0003] In the existing dairy product production and processing process, milk collection trucks need to connect the containers on their truck body to the milk storage tanks using pipes. To ensure the sealing of the connection structure, a threaded structure is generally used for assembly. Therefore, multiple rotations are required during installation to ensure a tight connection between the output pipe and the milk collection pipe, thereby maintaining the sealing between the pipes. This method is time-consuming and labor-intensive. Furthermore, the threaded assembly structure will wear down due to frequent disassembly and assembly, which will damage the protective layer on the surface of the threaded structure and cause corrosion. At the same time, gaps will appear in the assembly structure, resulting in milk leakage during transportation. Utility Model Content

[0004] Based on the above description, this utility model provides a self-priming pump interface device for milk collection, which solves the problem that existing milk transfer interfaces mostly use bolted connections, which are not only time-consuming and laborious to disassemble and assemble, but also cause wear on the surface of the threaded structure due to frequent use, resulting in gaps when the two pipes are assembled together, leading to milk leakage.

[0005] This utility model is achieved through the following technical solution:

[0006] A self-priming pump interface device for milk collection includes a storage tank. A mounting base is provided on one end face of the storage tank. A self-priming pump is provided in the mounting base. One end of the self-priming pump extends inward and communicates with the inside of the storage tank. The other end of the self-priming pump extends outward and is connected to a milk discharge pipe. The other end of the milk discharge pipe is connected to a container on a milk collection cart through a connecting pipe. A self-sealing component is provided at the connection between the milk discharge pipe and the external pipe.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the self-sealing assembly includes a groove arranged around the inside of the milk discharge tube, a sealing plug movably installed inside the groove, and a fixing ring spaced apart at the outward end of the groove. The outer wall of the fixing ring is fixedly connected to the inner wall of the milk discharge tube, and a positioning hole is provided at the center of the fixing ring. A frustum-shaped protrusion is provided at the center of the sealing plug. When the end face of the sealing plug is in contact with the surface of the fixing ring, the protrusion is inserted into the positioning hole and completely seals the inside.

[0009] Furthermore, the sealing plug and the fixing ring are provided with a matching annular groove structure on their opposite sides.

[0010] Furthermore, each of the aforementioned grooves is provided with an elastic support member, the bottom end of which is fixedly connected to the inner wall of the groove, and the telescopic end of the top of the elastic support frame is fixedly connected to the end face of the sealing plug.

[0011] Furthermore, the end of the connecting tube is provided with a connecting seat, which is circular and has a rectangular flange on the outer side wall. The top of the connecting seat is also provided with a plug with a conical structure. The inner side wall of the milk discharge tube is provided with a guide groove. The connecting seat moves along the guide groove toward the inside of the milk discharge tube and makes the top of the plug fit tightly with the bottom of the sealing plug.

[0012] Furthermore, the bottom end of the guide groove is provided with an annular sealing groove, an expansion sleeve is arranged around the outer wall of the connecting seat, and the interior of the expansion sleeve is hollow. The bottom surface of the connecting seat is also provided with an air supply pipe that communicates with the rubber ring, and an air pump is provided on the air supply pipe.

[0013] Furthermore, the surface of the connector is also surrounded by several through holes, through which the milk discharge tube communicates with the interior of the connecting tube.

[0014] Furthermore, the milk discharge tube is also equipped with a flow valve, and the surface of the flow valve is equipped with a display screen for displaying the delivery volume.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0016] This application improves upon the existing self-priming pump interface for milk collection by using a self-sealing component to replace the existing pipe sealing structure. Combined with its internal insert plate structure and expansion structure, it can quickly connect the container on the milk collection cart to the milk storage container. During this process, it can also ensure the sealing of the connection between the two. Compared with the traditional bolt connection, it is not only convenient to use, but also avoids assembly gaps caused by wear due to repeated disassembly and assembly. Attached Figure Description

[0022] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0024] Combination Figure 1-4 As shown, a self-priming pump interface device for collecting milk includes:

[0025] Storage tank 1, a container for temporarily storing milk;

[0026] The self-priming pump 2 is fixedly installed on one side of the storage tank 1 via the mounting base 11. It is mainly used to draw milk from the tank and inject it into the container of the milk collection cart for transfer and production.

[0027] Milk discharge pipe 3 is located at the output end of self-priming pump 2 and is used to connect to the pipe on the external milk collection cart container;

[0028] Connecting pipe 4 is installed on the milk collection cart and is connected to the containers on the milk collection cart.

[0029] The self-sealing component 5 is located inside the milk discharge tube 3 and is used to connect the milk discharge tube 3 and the connecting tube 4. When the two are connected, the self-sealing component 5 is opened; when the two are separated, the self-sealing component 5 seals the inside of the milk discharge tube 3.

[0030] Specifically, in this embodiment, the self-sealing component 5 includes multiple grooves 52 arranged around the inner wall of the milk discharge tube 3. Each groove 52 extends outward into a long rectangular structure, and a sealing plug is provided inside the milk discharge tube 3. The main body of the sealing plug is arranged concentrically with the milk discharge tube 3, and both the upper and lower ends are provided with frustum-shaped protrusions. A rectangular protrusion is also provided outward on its outer side wall. The protrusions are movably assembled with the grooves 52 so that they can move horizontally along the side wall of the grooves 52.

[0031] In addition, a fixing ring 51 is provided on the inner wall of the outward end of the milk tube 3. The fixing ring 51 has a circular through hole at its center and is arranged close to the side of the slide groove 52. When the sealing plug slides to the end of the slide groove 52, the protrusion on the bottom surface of the sealing plug is inserted into the through hole to form a seal.

[0032] In this structure, the slide 52 should also be provided with an elastic support 54. The elastic support 54 can be a spring or a damping rod, etc., to continuously apply an outward thrust to the sealing plug 53, so that in its natural state, the sealing plug and the fixing ring 51 are squeezed together to form a seal. In order to further improve the sealing effect between the two, an additional matching annular groove can be added to the surface of the sealing plug 53 and the fixing ring 51. The two fit together to achieve a multi-level annular seal, ensuring that when the milk discharge tube 3 is separated from the connecting tube 4, the milk will be completely sealed by the sealing plug 53 and no leakage will be detected.

[0033] Based on the self-sealing structure described above, the structure still requires external pushing to open. Therefore, a connecting seat 41 should be provided at the top of the connecting tube 4. The connecting seat 41 is a cylindrical structure and is fitted onto the outer wall of the connecting tube 4. At the same time, a flange is provided on its outer wall. A guide groove 31 is provided at the port of the milk discharge tube 3. The two form a spline assembly structure, so that the top of the connecting tube 4 can be directly inserted into the inside of the milk discharge tube 3.

[0034] In addition, a tapered connector 42 is provided at the top of the connector 41. The connector 42 is hollow inside and has several holes arranged around its surface. Its top should also have a flat surface. When the connector 41 is slidably assembled with the milk discharge tube 3, the flat surface at the top of the connector 42 is exactly in contact with the flat surface at the bottom of the sealing plug 53 and continuously squeezes inward, eventually causing the sealing plug 53 to separate from the fixing ring 51. At this time, the milk discharge tube 3 is directly connected to the connecting tube 4.

[0035] However, during continuous delivery, the liquid has a certain impact force, which will not only seep out through the gap between the two parts, but also push the connecting seat 41 outward. Therefore, in order to improve the sealing performance here, an annular sealing groove 32 should be provided on the inner wall of the milk discharge tube 3. At the same time, an expansion sleeve 43 (an air bladder structure in the middle structure, which can be made of rubber or other elastic materials) is provided on the outer wall of the connecting seat 41. In addition, an air supply pipe 44 is provided inside the connecting seat 41 to supply air to the expansion sleeve 43. An air pump is provided on the air supply pipe 44, so that the expansion sleeve 43 can be expanded by inputting air and then tightly fitted with the inner wall of the sealing groove 32 to form a seal. At the same time, the spline structure mentioned above is used to complete the fixation.

[0036] Throughout the entire operation, there is no longer a need to use bolts for locking and fixing. The staff only needs to control the opening and closing of the air pump to easily insert the connecting tube 4 into the milk discharge tube 3, making the milk transfer process more convenient and effectively improving the efficiency of the transfer work.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
