[0002] As a nutritious daily drink, milk has a wide consumer market worldwide. With the improvement of people's living standards and the enhancement of health awareness, the requirements for the quality and variety of milk and its products are becoming increasingly diversified. In the milk processing process, concentration is a key link. It not only improves the nutritional value and storage stability of milk, but also meets the requirements of different dairy production processes. For example, when producing milk powder, cheese, cream and other products, milk needs to be concentrated to increase the solid content of the raw materials.

[0003] The traditional filter tube installation structure is often complicated and requires the use of multiple professional tools for disassembly and installation. In daily cleaning and maintenance, the frequent use of complex tools increases labor intensity and reduces work efficiency. Some old models require unscrewing multiple bolts and loosening complex connectors to remove the filter tube. Secondly, the stirring method of some stirring equipment is relatively simple, usually relying on a simple stirring paddle to stir at a fixed position. This stirring method is difficult to ensure that the milk is evenly mixed in the entire container and is prone to uneven local composition. During RO membrane filtration, the uneven milk composition will cause inconsistent filtration load on the membrane surface, affecting the filtration efficiency and the service life of the membrane. Therefore, a milk RO membrane concentration device is proposed to solve the above problems. Utility Model Content

The mounting ring 5 and the filter tube 4 are mounted or disassembled on the filter tube 4 by bolts, and the right end of the filter tube 4 is connected to the discharge pipe. The disassembly and assembly method of the discharge pipe is the same as that of the movable sleeve 7 and the connecting pipe 10. The left end of the mounting ring 5 is fixedly connected with a fixed pipe 6. The fixed pipe 6 allows the milk to be filtered to pass through the fixed pipe 6 into the filter tube 4 for subsequent processing. The outer wall of the fixed pipe 6 slides It is connected with a movable sleeve 7, and the left end of the movable sleeve 7 has a rubber pad, which can achieve the effect of sealing after the movable sleeve 7 and the connecting pipe 10 are in contact. The outer wall of the movable sleeve 7 is fixedly connected with a plug block 8, and the outer wall of the plug block 8 is plugged with a fixed block 9. The outer wall of the fixed block 9 is fixedly connected with a connecting pipe 10. The connecting pipe 10 mainly connects the movable sleeve 7, and an opening corresponding to the rubber pad is opened on the connecting pipe 10, so that the rubber pad can contact the opening. A limiting mechanism is provided on the inner wall of the fixed block 9. The left end of the connecting pipe 10 is provided with a delivery valve 19 through the delivery pipe 13, which is opened and closed according to the actual milk processing situation. Delivery valve 19, the right end of the delivery valve 19 is fixedly connected with a balancing cylinder 20, which serves as an intermediate storage container. It can store excess milk when the flow rate is large and release the stored milk when the flow rate is small, thereby effectively buffering such flow fluctuations. A stirring assembly is provided at the top of the balancing cylinder 20, and the limiting mechanism includes a wedge 12. The wedge 12 passes through and is slidably connected to the inner wall of the fixed block 9. A notch corresponding to the wedge 12 is provided on the fixed block 9, allowing the wedge 12 to move back and forth along the fixed block 9. The front end of the wedge 12 is elastically connected to the fixed block 9 through a return spring 11.

[0033] Reference Figure 1 and Figure 5The stirring assembly includes a motor 14, which is arranged at the top of the balancing cylinder 20. The output end of the motor 14 is fixedly connected to a rotating shaft 15. There is a convex block on the rotating shaft 15, which can allow the convex block to rotate with the stirring rod 18, or allow the stirring rod 18 to move vertically along the outer wall of the rotating shaft 15. The outer wall of the rotating shaft 15 is slidably connected with the stirring rod 18, which can be used to stir the milk in the balancing cylinder 20 to prevent it from sedimentation. The outer wall of the stirring rod 18 is rotatably connected to a guide plate 17, which can be used to move the stirring rod 18 vertically with the guide plate 17 to achieve stirring at different positions during the stirring process. The top of the guide plate 17 is fixedly connected to a hydraulic rod 16, which is arranged at the top of the balancing cylinder 20 through a bracket. The movable end of the hydraulic rod 16 passes through and is slidably connected to the inner wall of the balancing cylinder 20.

[0034] Reference Figure 2-Figure 4 The front end of the wedge 12 is fixedly connected to one end of the return spring 11. When the wedge 12 moves forward, it compresses the return spring 11. When resetting, the elastic force of the return spring 11 is used to restore the wedge 12. The other end of the return spring 11 is fixedly connected to the inner wall of the front end of the fixed block 9. The wedge 12 is inserted into the inner side wall of the plug 8. Figure 3 and Figure 4 As shown, a notch corresponding to the wedge block 12 is provided on the plug block 8, which allows the wedge block 12 to be inserted into it to limit the plug block 8 in one direction. The left end of the connecting pipe 10 is fixedly connected to one end of the delivery pipe 13, and the other end of the delivery pipe 13 is fixedly connected to the left end of the delivery valve 19. The right end of the connecting pipe 10 is in contact with the left end of the movable sleeve 7, and the balancing cylinder 20 is arranged on the top of the support seat 1.

[0035] Working principle: First, when you need to disassemble the filter tube 4, you only need to press the wedge 12 with your hands at the same time to move the wedge 12 forward and compress the return spring 11 to separate the wedge 12 from the inner side wall notch of the insert 8. Then, move the movable sleeve 7 with the insert 8 to the right along the outer wall of the fixed tube 6 to make the movable sleeve 7 and the connecting tube 10 no longer contact. After no longer contacting, release the wedge 12 and use the reverse elastic force of the return spring 11 to reset the wedge 12 backward. At the same time, the operation method of the discharge pipe at the right end of the filter tube 4 is the same. Finally, move the filter tube 4 out of the outer wall of the connecting frame 3. When the filter tube 4 mounting ring 5 is disassembled and cleaned, its inner wall can be cleaned. When the filter tube 4 needs to be installed, the filter tube 4 only needs to be placed on the outer wall of the connecting frame 3, and the movable sleeve 7 is moved to the left to make the movable sleeve 7 contact with the connecting tube 10, and the plug block 8 is inserted into the notch of the fixed block 9, so that the left end of the plug block 8 squeezes the inclined surface of the wedge block 12, and the wedge block 12 moves forward and compresses the reset spring 11. When the inner side wall notch of the plug block 8 coincides with the wedge block 12, the reverse elastic force of the reset spring 11 is used to reset the wedge block 12, and the wedge block 12 is plugged into the inner side wall of the plug block 8 to complete the installation.

[0036] During use, the milk RO membrane concentration device can start the motor 14 to rotate the rotating shaft 15 and the stirring rod 18, and then start the hydraulic rod 16 to make the hydraulic rod 16 move vertically with the guide plate 17 and the stirring rod 18, so that the stirring position changes while rotating, thereby improving the stirring effect of the milk.

[0037] When the milk in the balancing cylinder 20 needs to be transported to the filter tube 4 for processing, it is transferred to the delivery valve 19 through the existing delivery pump in the balancing cylinder 20, and then the delivery valve 19 is transported to the connecting pipe 10 through the delivery pipe 13, and finally passes through the movable sleeve 7 and the fixed pipe 6 and the filter tube 4.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
