Technical Field

[0001] This invention relates to the field of high-speed mixing tank technology, and more particularly to a high-speed mixing tank with an internal wall cleaning function. Background Technology

[0002] High-speed mixing tanks are highly efficient mixing equipment that utilizes high-speed rotating impellers to rapidly and powerfully mix, disperse, and knead materials. These tanks are indispensable core equipment in dairy product pretreatment processes, directly determining whether raw materials can be perfectly integrated into uniform, stable intermediate products that meet process requirements. This lays a solid foundation for subsequent homogenization, sterilization, fermentation, concentration, and drying processes, ultimately ensuring the superior quality of the final dairy products.

[0003] After the mixing process is completed, the high-speed mixing tank needs to be cleaned. CIP cleaning is a convenient and efficient way to clean the high-speed mixing tank. However, traditional CIP cleaning methods cannot remove stubborn residues such as scale and high-viscosity materials from the inner wall of the mixing tank, and the cleaning effect on the inner wall of the mixing tank is limited. Therefore, there is an urgent need for a high-speed mixing tank with an inner wall cleaning function. Summary of the Invention

[0015] The inner walls of the sub-arc plates are all in close contact with the groove ring, and there is a gap between the outer wall of the sub-arc plates and the tank body. The top surface of the sub-arc plates is inclined towards the gap.

[0016] In addition, in a preferred configuration, a connecting frame is fixedly provided on both the main moving part and the auxiliary moving part. The connecting frame extends out from the side cavity. The connecting frame on the main moving part has an upper water guiding cavity inside, and the upper water guiding cavity is supplied through the main arc plate.

Detailed Implementation

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] See Figure 1-2 The top of the tank 1 is equipped with a top cover 11, on which a stirring shaft 12 and a fixing ring 2 are installed. A grooved ring 21 is installed at the bottom of the fixing ring 2. Two main scrapers 5 and a secondary scraper 6 are movably arranged below the grooved ring 21. The main scrapers 5 are all located on the inner wall of the tank 1 and rotate to scrape away stubborn stains on the inner wall of the tank 1.

[0043] This design integrates both the stirring shaft 12 and the scraping assembly proposed in this application onto the top cover 11, allowing them to be disassembled simultaneously. This facilitates removal from the tank 1 for deep cleaning. The rotation of the stirring shaft 12 enables mixing of the materials within the tank 1. This is prior art and will not be elaborated upon further.

[0044] See Figure 3-4 The fixing ring 2 is installed at the bottom of the top cover 11. A ring pipe 41 is fixedly installed inside the top cover 11. An inlet pipe 4 is connected to the top of the ring pipe 41, and four drive pipes 42 are installed at the bottom of the ring pipe 41. The drive pipes 42 all pass through the fixing ring 2 at an angle, so that the water flow sprayed from the drive pipes 42 can drive the main moving part 3 or the auxiliary moving part 30 in the groove ring 21, thereby driving the main scraper 5 to rotate.

[0045] In this device, the inlet pipe 4 is connected to a branch pipe in the CIP system during operation. Therefore, during CIP cleaning, various cleaning fluids from the CIP system can be simultaneously sprayed from the drive pipe 42. This allows the device to work in tandem with the CIP system for synchronous cleaning, enabling the removal of stubborn stains from the inner wall of the tank 1 using the main scraper 5 and auxiliary scraper 6. It is worth noting that parameters such as the inlet pressure and water flow in the inlet pipe 4 need to be adjusted according to the actual operating conditions. These parameters can be easily obtained when implementing this technical solution, and therefore will not be elaborated upon further.

[0046] See Figure 4-9 A grooved ring 21 is fixedly installed at the bottom of the fixed ring 2. The grooved ring 21 has an annular movable groove inside, and multiple drainage holes 211 are provided at the bottom of the movable groove. The drainage holes 211 allow excess water to be discharged from the grooved ring 21. It is worth noting that the total drainage volume of the drainage holes 211 is significantly less than the water spray volume of the drive pipe 42.

[0047] The groove ring 21 contains two main moving parts 3 and four auxiliary moving parts 30. Each main moving part 3 has auxiliary moving parts 30 fixedly mounted on both sides by a main arc plate 32, and the auxiliary moving parts 30 on adjacent sides are fixedly connected by an auxiliary arc plate 33.

[0048] Both the main moving part 3 and the auxiliary moving part 30 are adapted to move within the groove ring 21. Driven by the water flow sprayed from the four drive pipes 42, the main moving part 3 and the auxiliary moving part 30 can be pushed to rotate within the groove ring 21, thereby driving the main scraper parts 5 on both sides to rotate synchronously.

[0049] The inner ring of the grooved ring 21 is fixedly connected to the fixed ring 2, and an annular side cavity 22 is left between the outer ring of the grooved ring 21 and the fixed ring 2. This allows excess water in the grooved ring 21 to overflow through the side cavity 22.

[0050] Both the main moving part 3 and the auxiliary moving part 30 are fixedly equipped with connecting brackets 31, which extend from the side cavity 22. Furthermore, the connecting brackets 31 on the main moving part 3 each have an upper water guiding cavity 34 inside. The connecting brackets 31 improve the stability of the main moving part 3 and the auxiliary moving part 30 during movement.

[0051] The inner and outer walls of the main arc-shaped plate 32 are in close contact with the groove ring 21 and the tank body 1, respectively, and the top surface of the main arc-shaped plate 32 is inclined from the auxiliary moving part 30 towards the main moving part 3. This allows a portion of the water overflowing from the side cavity 22 to flow onto the main arc-shaped plate 32, and then the water flows through the main arc-shaped plate 32 into the upper water guide cavity 34. It is worth noting that although the main arc-shaped plate 32 is in a rotating state at this time, its rotation speed is relatively slow, so the water flow on the main arc-shaped plate 32 is not greatly affected by inertia, and it can still flow into the upper water guide cavity 34 through the inclined main arc-shaped plate 32.

[0052] The inner walls of the secondary arc-shaped plates 33 are all in close contact with the groove ring 21, while a gap is left between the outer walls of the secondary arc-shaped plates 33 and the tank body 1, and the top surfaces of the secondary arc-shaped plates 33 are all inclined towards the gap. This allows another part of the water overflowing from the side cavity 22 to flow onto the secondary arc-shaped plates 33, and then the water flow is guided to the inner wall of the tank body 1 through the inclined surfaces on the secondary arc-shaped plates 33, so as to achieve continuous wetting of the inner wall of the tank body 1.

[0053] See Figure 10-18 The top of the main scraper 5 is fixedly connected to the connecting frame 31 on the main movable part 3. The main scraper 5 has a lower water guiding cavity 52 inside, which is adapted to communicate with the upper water guiding cavity 34. The lower water guiding cavity 52 is provided with a first water outlet 521 and a second water outlet 522. This allows water to flow out from the first water outlet 521 and the second water outlet 522 simultaneously.

[0054] The main scraper 5 has a magnetic post 51 fixedly mounted above it, and multiple guide posts 53 are fixedly mounted on the magnetic post 51. The ends of the guide posts 53 are all fixedly connected by anti-detachment posts 531, and the auxiliary scraper 6 has a guide cavity 612 adapted to each guide post 53. This allows the auxiliary scraper 6 to move under the guidance of the guide posts 53, and the anti-detachment posts 531 are located in the cavity 61, preventing the auxiliary scraper 6 from falling off the guide posts 53. This allows the auxiliary scraper 6 to move on the scraping surface of the main scraper 5, thereby removing stubborn stains remaining on the scraping surface of the main scraper 5, preventing stubborn stains scraped off by the main scraper 5 from remaining on the scraping surface and being unable to be removed.

[0055] The area on the secondary scraper 6 facing the magnetic post 51 is made of a magnetic material that is compatible with and repulsive to the magnetic post 51. This allows the magnetic post 51 to push the secondary scraper 6 outward by magnetic force, at which point the secondary scraper 6 can move diagonally upward by being guided by the guide post 53.

[0056] The auxiliary scraper 6 has a vertical cavity 61 on the side facing the main scraper 5. Since the auxiliary scraper 6 moves on the main scraper 5, and the bottom of the vertical cavity 61 is connected to the water tank 62 through the connecting cavity 611, the water flowing out of the first outlet 521 and the second outlet 522 can be guided into the water tank 62 through the vertical cavity 61.

[0057] When the auxiliary scraper 6 is positioned obliquely upward, the vertical cavity 61 covers the first outlet 521 and the second outlet 522. At this time, the water flowing out of the first outlet 521 and the second outlet 522 flows through the vertical cavity 61 into the water tank 62. This increases the water flow rate into the water tank 62, thereby accelerating the downward movement speed of the auxiliary scraper 6 and reducing the dwell time of the auxiliary scraper 6 on the scraping surface of the main scraper 5.

[0058] As the water level in the water tank 62 rises, the weight of the auxiliary scraper 6 increases. At this point, the auxiliary scraper 6 gradually overcomes the repulsive magnetic force between itself and the magnetic column 51 and moves diagonally downwards. With the movement of the auxiliary scraper 6, the vertical cavity 61 no longer covers the second outlet 522. The water discharged from the second outlet 522 can then flow directly onto the scraping surface of the main scraper 5, thus rinsing the main scraper 5 and assisting in removing stubborn residual dirt.

[0059] However, the first outlet 521 is always located at the cover of the vertical cavity 61, which allows the water flowing out of the first outlet 521 to always enter the water tank 62, so as to achieve continuous downward movement of the auxiliary scraper 6.

[0060] It is worth noting that the inner wall of the second outlet 522 is provided with multiple uneven flow-blocking elements, which can reduce the outflow velocity of the water from the second outlet 522. This ensures that the water flows slowly from the second outlet 522 and along the scraping surface of the main scraper 5, rather than being sprayed out of the second outlet 522. The flow-blocking elements are existing technology; as long as they can reduce the water flow velocity in the second outlet 522, they are sufficient and will not be described in detail.

[0061] The bottom of the water tank 62 has a cavity 621, and a movable plate 7 is installed inside the cavity 621. A magnetic plate 711 is fixedly installed on the movable plate 7 via a connecting rod 71. When the movable plate 7 moves outward, the cavity 621 opens, and the water in the water tank 62 flows out automatically.

[0062] A sub-magnetic component 622 is fixedly installed on one side of the bottom cavity 621. The sub-magnetic component 622 and the female magnetic component 72 at the bottom of the movable plate 7 are attracted to each other by magnetic force. This allows the female magnetic component 72 to be attracted by the sub-magnetic component 622 by magnetic force, thereby driving the movable plate 7 to move and reset synchronously, thus sealing the bottom cavity 621 and enabling water storage in the water tank 62.

[0063] During water storage, as the auxiliary scraper 6 gradually moves downward, the water tank 62 gradually moves synchronously to one side of the magnetic column 51. At this time, the magnetic plate 711 on the movable plate 7 moves to the side of the magnetic column 51. Since the magnetic plate 711 and the magnetic column 51 repel each other through magnetic force, the magnetic plate 711 can move outward through the repulsive magnetic force, thereby driving the movable plate 7 to move outward synchronously. At this time, the water tank 62 releases water.

[0064] The repulsive magnetic force between the magnetic plate 711 and the magnetic column 51 is greater than the attractive magnetic force between the sub-magnetic component 622 and the mother magnetic component 72. Furthermore, the mother magnetic component 72 can prevent the movable plate 7 from falling off, thus preventing it from detaching from the bottom cavity 621.

[0065] In this embodiment, the access pipe 4 is connected to a branch pipe in the CIP system, and the flow rate of the liquid entering the access pipe 4 is adjusted by a flow rate and pressure regulating mechanism in the prior art.

[0066] When cleaning tank 1, simply drive the CIP system to perform routine cleaning of tank 1. At this time, the cleaning fluid in the CIP system simultaneously enters the inlet pipe 4, and then the cleaning fluid is diverted through the ring pipe 41 and sprayed out from the drive pipe 42.

[0067] The sprayed cleaning fluid enters the tank ring 21 and pushes the main moving part 3 and the auxiliary moving part 30 to move, thereby driving the main scraper 5 and the auxiliary scraper 6 to move synchronously. In this way, the stubborn residual stains on the inner wall of the tank 1 can be scraped off by the rotation of the main scraper 5.

[0068] Furthermore, as the water level in the groove ring 21 rises, the excess water overflows from the side cavity 22. A portion of the water overflows onto the secondary arc plate 33, and then the water is guided to the inner wall of the tank 1 through the inclined surface on the secondary arc plate 33, so as to achieve continuous wetting of the inner wall of the tank 1.

[0069] Another portion of the water overflows onto the main arc plate 32, and then the water flows automatically into the upper water guide cavity 34 through the inclined surface on the main arc plate 32. Next, the water flows from the upper water guide cavity 34 into the lower water guide cavity 52, and finally the water is divided into two streams and flows out from the first outlet 521 and the second outlet 522 respectively.

[0070] Furthermore, when the auxiliary scraper 6 is positioned obliquely upwards, the vertical cavity 61 covers the first outlet 521 and the second outlet 522. At this time, the water flowing out of the first outlet 521 and the second outlet 522 flows through the vertical cavity 61 into the water tank 62. This increases the water flow rate into the water tank 62, thereby accelerating the downward movement speed of the auxiliary scraper 6 and reducing the dwell time of the auxiliary scraper 6 on the scraping surface of the main scraper 5.

[0071] As the water level in the water tank 62 rises, the weight of the auxiliary scraper 6 increases. At this point, the auxiliary scraper 6 gradually overcomes the repulsive magnetic force between itself and the magnetic column 51 and moves diagonally downwards. Furthermore, as the auxiliary scraper 6 moves, the vertical cavity 61 no longer covers the second outlet 522. The water flowing from the second outlet 522 can then directly flow onto the scraping surface of the main scraper 5, thus rinsing the main scraper 5 and assisting in removing stubborn residual dirt. However, the first outlet 521 remains within the coverage area of ​​the vertical cavity 61, ensuring that the water flowing from the first outlet 521 can always enter the water tank 62, allowing the auxiliary scraper 6 to continue moving downwards.

[0072] When the auxiliary scraper 6 moves completely to the bottom, it overcomes the repulsive magnetic force with the magnetic column 51 and moves to one side of the magnetic column 51. At the same time, the magnetic plate 711 on the movable plate 7 also moves to one side of the magnetic column 51. The magnetic plate 711 can then move outwards due to the repulsive magnetic force with the magnetic column 51, thus driving the movable plate 7 to move outwards synchronously. At this point, the bottom cavity 621 of the water tank 62 is opened, and the water in the water tank 62 can flow out from the bottom cavity 621.

[0073] As water flows out of the water tank 62, the overall weight of the auxiliary scraper 6 decreases. At this point, the auxiliary scraper 6 can no longer overcome the repulsive magnetic force between itself and the magnetic column 51, and the auxiliary scraper 6 can be ejected outward by the repulsive magnetic force. At this time, the auxiliary scraper 6 moves diagonally upward to reset. During its reset process, it can scrape away the dirt on the scraping surface of the main scraper 5, so as to avoid dirt residue remaining on the scraping surface of the main scraper 5 when it scrapes the dirt on the inner wall of the tank 1.

[0074] Furthermore, after the auxiliary scraper 6 pops outward, the magnetic plate 711 is no longer in contact with the magnetic post 51. At this time, the female magnetic component 72 can automatically move towards the female magnetic component 622 by the magnetic force of attraction, so as to drive the movable plate 7 to move and reset synchronously. At this time, the movable plate 7 is sealed in the bottom cavity 621 again, and the water tank 62 can fill with water again.

[0075] Furthermore, in this application, no sealing structures are provided at the locations through which water flows, such as the groove ring 21, the main arc plate 32, the secondary arc plate 33, and the vertical cavity 61, to reduce structural complexity. Also, all dead corners in this application are chamfered to prevent dirt accumulation. Because no sealing structures are provided, slight water leakage may occur during operation. However, since this is during the cleaning process and the water is located inside the tank 1, and the CIP system itself also sprays water, it does not affect the cleaning effect.

[0076] In this application, the fixing ring 2, the grooved ring 21, and the related components on the main scraper 5 and the auxiliary scraper 6 are all located above the upper tank 1. This prevents a large amount of the mixture from contacting the tank 1 during mixing. Furthermore, by using lightweight materials and structures, the power required to drive the rotation of the drive pipe 42 is reduced. An anti-stick coating is applied to the exterior to reduce the probability of dirt residue adhering to its surface. And during scraping, the main scraper 5 and the auxiliary scraper 6 can be further cleaned by the rinsing of water.

[0077] Furthermore, since the inlet pipe 4 is connected to the CIP system, the scraper in this application rotates synchronously during CIP system cleaning to scrape off the residue on the inner wall of the tank 1, and the water sprayed in this application is consistent with the water sprayed in the CIP system at different stages of CIP cleaning.

[0078] It is worth noting that the structure described in this application is only for routine cleaning of the mixed tank 1 under normal operating conditions, in conjunction with a CIP system. If a deep cleaning of the tank 1 is required, the tank 1 still needs to be disassembled for cleaning.

[0079] In this invention, the stirring shaft 12 can mix and stir the materials in the tank 1. The water jet from the drive pipe 42 can drive the main moving part 3 and the auxiliary moving part 30 to move, so as to drive the main scraper 5 to move synchronously and scrape off the residue on the inner wall of the tank 1. Furthermore, the auxiliary scraper 6 can remove the stains on the scraping surface of the main scraper 5. This method can enhance the cleaning effect on stubborn stains on the inner wall of the tank 1 on the basis of CIP cleaning.

[0080] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
