Description

Technical Field

[0001] This utility model relates to the field of food science and engineering, and in particular to an ultrafiltration membrane rinsing device. Background Technology

[0002] Ultrafiltration membranes are polymer or inorganic membranes with an asymmetric microporous structure. Driven by a pressure difference, they selectively retain solutes and other substances in liquids while allowing water and other substances to permeate through the membrane pores. They are widely used in food processing and other fields. In the dairy industry, ultrafiltration membranes are often used in processes such as concentrating high-concentration milk, retaining beneficial components and removing impurities through membrane retention. However, high-concentration milk contains a large amount of viscous substances. During filtration, these substances easily adhere to the surface of the ultrafiltration membrane and the inside of the pores, forming a fouling layer. As filtration time increases, this fouling layer thickens, leading to increased water resistance, decreased filtration flux, and potentially shortened lifespan due to persistent viscous substances adhering to the membrane surface. Therefore, after filtering high-concentration milk, the ultrafiltration membrane must be rinsed promptly.

[0003] When a traditional ultrafiltration membrane flushing device flushes an ultrafiltration membrane that has filtered high-concentration milk, viscous substances such as proteins and fats have a strong adhesion to the membrane surface. Simple water flushing is insufficient to break the binding force between the viscous residue and the membrane surface, resulting in some viscous residue still adhering to the membrane surface and inside the membrane pores. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an ultrafiltration membrane flushing device, which aims to improve the problem that some viscous residual substances still adhere to the membrane surface and membrane pores.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrafiltration membrane flushing device, comprising a base, a motor fixedly connected to the outer wall of the base, a transmission column fixedly disposed at the output end of the motor, an eccentric wheel fixedly connected to the outer wall of the transmission column, a bracket rotatably connected to the outer wall of the eccentric wheel, a guide column fixedly connected to the outer wall of the base, a spring fixedly connected inside the guide column, a sleeve fixedly connected to the outer wall of the spring, a connecting frame fixedly connected to the outer wall of the sleeve, a clamping assembly fixedly connected to the outer wall of the connecting frame, and a flushing assembly disposed on the outer wall of the clamping assembly, the flushing assembly being used to clean the ultrafiltration membrane.

[0006] The above technical solution first starts the motor to drive the transmission column to rotate, which in turn drives the eccentric wheel to rotate, thereby lifting the support frame and the connecting frame to rise. At the same time, the sleeve rises to stretch the spring. When the eccentric wheel rotates away from the highest point, it drives the connecting frame to fall, and the spring is released from the stretched state. Therefore, it will be driven by the spring rebound force to vibrate slightly. This can enhance the removal of viscous residues, reduce the risk of membrane fouling, and also achieve the effect of using the water inside the cleaning tank to vibrate and clean the membrane.

[0007] Preferably, the rinsing assembly includes a cleaning tank, the outer wall of which is connected to the outer wall of the clamping assembly, a baffle is fixedly connected to the outer wall of the cleaning tank, a dual air-water jet nozzle is fixedly connected to the inside of the cleaning tank, a filter membrane body is slidably connected to the inside of the baffle, and a sealing cap is fixedly connected to the outer wall of the filter membrane body.

[0008] Preferably, the outer wall of the sleeve is slidably connected to the outer wall of the guide post, and the outer wall of the bracket is fixedly connected to the outer wall of the connecting frame.

[0009] Preferably, the outer wall of the sealing cap is connected to the inside of the baffle, and the outer wall of the filter membrane body is connected to the inside of the cleaning tank.

[0010] Preferably, the clamping assembly includes a second motor, the outer wall of which is fixedly connected to the outer wall of the connecting frame. A lead screw is fixedly provided at the output end of the second motor, and a sliding plate is threadedly connected to the outer wall of the lead screw. A stop block is fixedly connected to the outer wall of the connecting frame. A connecting block is rotatably connected inside the sliding plate, and a transmission block is rotatably connected inside the connecting block. A clamping block is fixedly connected to the outer wall of the transmission block.

[0011] Preferably, the outer wall of the lead screw is rotatably connected to the inside of the connecting frame, and the outer wall of the lead screw is rotatably connected to the inside of the stop block.

[0012] Preferably, the outer wall of the slide plate is slidably connected to the outer wall of the connecting frame, and the outer wall of the transmission block is rotatably connected to the outer wall of the connecting frame.

[0013] Preferably, the outer wall of the clamping block is connected to the outer wall of the cleaning tank.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the starting motor drives the transmission column to rotate, which in turn drives the eccentric wheel to rotate, thereby lifting the support frame to rise, driving the connecting frame to rise, and simultaneously driving the sleeve to rise and stretch the spring. When the eccentric wheel rotates away from the highest point, it drives the connecting frame to fall, and the spring is released from the stretched state. Therefore, it will be driven by the spring rebound force to vibrate slightly. Thus, it can achieve enhanced removal of viscous residues, reduce the risk of membrane fouling, and also achieve the effect of using the water inside the cleaning tank to vibrate and clean the membrane.

[0015] 2. In this utility model, the starting motor drives the lead screw to rotate, which in turn drives the slide plate to move, thereby driving the connecting block to rotate, and synchronously driving the transmission block to rotate. The clamping block and the transmission block move simultaneously. When the lead screw drives the slide plate to move towards the stop block, it causes the clamping blocks on both sides to gradually separate. When the lead screw drives the slide plate to move towards the connecting frame, it causes the clamping blocks on both sides to gradually close and achieve clamping. Therefore, it can ensure the stability of the cleaning tank and also achieve the effect of adapting to different cleaning tanks. Attached Figure Description

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of this utility model provides an ultrafiltration membrane rinsing device, including a base 1, a motor 2 fixedly connected to the outer wall of the base 1, a transmission column 3 fixedly provided at the output end of the motor 2, an eccentric wheel 4 fixedly connected to the outer wall of the transmission column 3, a bracket 5 rotatably connected to the outer wall of the eccentric wheel 4, a guide column 6 fixedly connected to the outer wall of the base 1, a spring 7 fixedly connected inside the guide column 6, a sleeve 8 fixedly connected to the outer wall of the spring 7, a connecting frame 9 fixedly connected to the outer wall of the sleeve 8, a clamping assembly 11 fixedly connected to the outer wall of the connecting frame 9, and a rinsing assembly connected to the outer wall of the clamping assembly 11. The rinsing assembly is used to clean the ultrafiltration membrane. Specifically, firstly, motor 2 is started, driving transmission column 3 to rotate, which in turn drives eccentric wheel 4 to rotate. Base 1 restricts motor 2 and transmission column 3, ensuring their positions do not change. Transmission column 3 restricts eccentric wheel 4, ensuring it rotates synchronously with transmission column 3, thereby lifting support 5. Since support 5 fixes connecting frame 9, it lifts connecting frame 9 as it rises. Connecting frame 9 fixes sleeve 8, ensuring it rises as it rises. Because spring 7 is fixed inside sleeve 8, it stretches when sleeve 8 rises. Guide column 6 restricts spring 7, ensuring it remains stretched. The sleeve 8 will not detach during extension. Since the sleeve 8 slides on the outer wall of the guide post 6, the movement direction of the sleeve 8 is restricted, ensuring that the sleeve 8 will not swing during movement. When the eccentric wheel 4 rotates away from the highest point, it drives the connecting frame 9 to descend. Since the spring 7 is released from the tension state, it will be driven to vibrate slightly by the rebound force of the spring 7 during descent. Therefore, it can enhance the removal of viscous residues, reduce the risk of membrane fouling, and also achieve the effect of vibrating and cleaning the membrane using the water inside the cleaning tank 12. The connecting frame 9 restricts the clamping assembly 11 to ensure that the position of the clamping assembly 11 will not change. The clamping assembly 11 restricts the rinsing assembly to ensure that the rinsing assembly will not fall off.

[0021] Reference Figure 1 , Figure 2 and Figure 3The rinsing assembly includes a rinsing tank 12, the outer wall of the rinsing tank 12 is connected to the outer wall of the clamping assembly 11, a baffle 13 is fixedly connected to the outer wall of the rinsing tank 12, a dual air-water jet nozzle 14 is fixedly connected to the inside of the rinsing tank 12, a filter membrane body 16 is slidably connected to the inside of the baffle 13, and a sealing cap 15 is fixedly connected to the outer wall of the filter membrane body 16. Specifically, the clamping assembly 11 restricts the cleaning tank 12 to ensure its stability and prevent it from falling off when subjected to vibration; the baffle 13 restricts the sealing cover 15 to prevent it from detaching due to excessive rotation; the cleaning tank 12 fixes the air-water dual-jet nozzle 14 to ensure its position does not change and its stability during operation. The air-water dual-jet nozzle 14 is activated to rinse the filter membrane body 16, initially cleaning away large amounts of sticky substances such as protein, fat, and lactose on its surface. Simultaneously, vibration moves the filter membrane body 16, exposing hard-to-clean parts for rinsing. Vibration can also be used to perform deep cleaning of the filter membrane body 16.

[0022] Reference Figure 4 The outer wall of the sleeve 8 is slidably connected to the outer wall of the guide post 6, and the outer wall of the bracket 5 is fixedly connected to the outer wall of the connecting frame 9; Specifically, the guide post 6 restricts the sleeve 8 to ensure that the sliding of the sleeve 8 will not deviate; the bracket 5 restricts the connecting frame 9 to ensure that the bracket 5 moves synchronously with the connecting frame 9.

[0023] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the sealing cap 15 is connected to the inside of the baffle 13, and the outer wall of the filter membrane body 16 is connected to the inside of the cleaning tank 12; Specifically, the baffle 13 restricts the sealing cover 15 to ensure that the sealing cover 15 will not leak when used in conjunction with the baffle 13; the cleaning tank 12 restricts the filter membrane body 16 to ensure that the filter membrane body 16 can be cleaned more thoroughly.

[0024] Reference Figure 1 , Figure 2 and Figure 5 The clamping assembly 11 includes a second motor 10. The outer wall of the second motor 10 is fixedly connected to the outer wall of the connecting frame 9. A lead screw 17 is fixedly provided at the output end of the second motor 10. A sliding plate 18 is threadedly connected to the outer wall of the lead screw 17. A stop block 19 is fixedly connected to the outer wall of the connecting frame 9. A connecting block 20 is rotatably connected inside the sliding plate 18. A transmission block 21 is rotatably connected inside the connecting block 20. A clamping block 22 is fixedly connected to the outer wall of the transmission block 21. Specifically, firstly, motor 10 is started, driving lead screw 17 to rotate, which in turn moves slide plate 18. Connecting frame 9 restricts motor 10 and lead screw 17, ensuring their positions do not change. By restricting slide plate 18 through connecting frame 9, the force driving slide plate 18 to rotate through lead screw 17 is converted into a linear motion force. Stop block 19 further restricts slide plate 18, preventing excessive movement. This, in turn, drives connecting block 20 to rotate. Because connecting block 20 affects the transmission... Block 21 restricts the movement of the connecting block 20, ensuring that the transmission block 21 rotates synchronously when the connecting block 20 is rotated by the sliding plate 18. The clamping block 22 is fixed by the transmission block 21, ensuring that the clamping block 22 and the transmission block 21 move simultaneously. When the lead screw 17 drives the sliding plate 18 to move towards the stop block 19, it causes the clamping blocks 22 on both sides to gradually separate. When the lead screw 17 drives the sliding plate 18 to move towards the connecting frame 9, it causes the clamping blocks 22 on both sides to gradually close and achieve clamping. Therefore, it can ensure the stability of the cleaning tank 12 and also achieve the effect of adapting to different cleaning tanks 12.

[0025] Reference Figure 5 The outer wall of the lead screw 17 is rotatably connected to the inside of the connecting frame 9, and the outer wall of the lead screw 17 is rotatably connected to the inside of the stop block 19; Specifically, the connecting frame 9 and the stop block 19 restrict and support the lead screw 17 to ensure that the position of the lead screw 17 does not change when driven by the motor 10, and that it will not fall off when subjected to external forces.

[0026] Reference Figure 5 The outer wall of the slide plate 18 is slidably connected to the outer wall of the connecting frame 9, and the outer wall of the transmission block 21 is rotatably connected to the outer wall of the connecting frame 9; Specifically, the connecting frame 9 restricts the slide plate 18 to ensure that the slide plate 18 does not rotate synchronously with the lead screw 17 when driven by the lead screw 17; the connecting frame 9 also restricts the transmission block 21 so that the transmission block 21 does not disengage when driven by the connecting block 20, thus preventing the cleaning tank 12 from falling off.

[0027] Referring to the figure, the outer wall of the clamping block 22 is connected to the outer wall of the cleaning tank 12; Specifically, the connecting frame 9 restricts the slide plate 18 to ensure that the slide plate 18 does not rotate synchronously with the lead screw 17 when driven by the lead screw 17; the connecting frame 9 also restricts the transmission block 21 so that the transmission block 21 does not disengage when driven by the connecting block 20, thus preventing the cleaning tank 12 from falling off.

[0028] Working principle: When the ultrafiltration membrane needs to be cleaned, the motor 2, which is restricted by the base 1, is started first to drive the transmission column 3 to rotate, which in turn drives the eccentric wheel 4 to rotate, thereby lifting the support 5 to rise, and at the same time driving the connecting frame 9 to rise, and simultaneously driving the sleeve 8 to rise to stretch the spring 7. When the eccentric wheel 4 rotates away from the highest point, it drives the connecting frame 9 to fall, and the spring 7 is released from the stretched state. Therefore, it will be driven by the rebound force of the spring 7 to vibrate slightly. Thus, it can achieve enhanced removal of viscous residues, reduce the risk of membrane fouling, and also achieve the effect of vibrating and cleaning the membrane using the water inside the cleaning tank 12. When it is necessary to change to a different cleaning tank 12, the motor 10 restricted by the connecting frame 9 is started first to drive the lead screw 17 to rotate, which in turn drives the slide plate 18 to move, thereby driving the connecting block 20 to rotate, and synchronously driving the transmission block 21 to rotate. The clamping block 22 moves at the same time as the transmission block 21. When the lead screw 17 drives the slide plate 18 to move towards the stop block 19, it drives the clamping blocks 22 on both sides to gradually separate. When the lead screw 17 drives the slide plate 18 to move towards the connecting frame 9, it drives the clamping blocks 22 on both sides to gradually close and achieve clamping. Therefore, the stability of the cleaning tank 12 can be guaranteed, and the effect of adapting to different cleaning tanks 12 can also be achieved. This device can not only enhance the removal of viscous residues and reduce the risk of membrane fouling, but also achieve the effect of vibrating and cleaning the membrane using the water inside the cleaning tank 12. It can also ensure the stability of the cleaning tank 12 and adapt to different cleaning tanks 12.
