Description

Technical Field

[0001] This utility model relates to the technical field of CIP cleaning systems, specifically a CIP tank cleaning device. Background Technology

[0002] In the production processes of industries such as food, beverage, and pharmaceuticals, CIP (Clean-in-Place) systems are widely used as an efficient and convenient cleaning method. This system eliminates the need to disassemble production equipment. It automatically cleans the inner walls of the equipment by pumping cleaning solutions (such as acids, alkalis, and hot water) into the tanks and pipes to be cleaned according to a preset program. The spraying and circulating action of the cleaning solution effectively removes residual materials, microorganisms, and other impurities, ensuring hygiene and safety during production.

[0003] To reduce production costs and minimize resource waste, the cleaning fluid in a CIP cleaning system is typically recycled. However, during the cleaning process, the cleaning fluid comes into full contact with residual impurities inside the tank, inevitably carrying a large amount of solid particles, colloidal substances, and other impurities with the recycled cleaning fluid. Therefore, a filtration system is usually installed in the cleaning fluid circulation loop to intercept and remove these impurities.

[0004] Currently, commonly used filtration mechanisms mostly employ structures such as filter screens and filter cartridges. While these can filter impurities to a certain extent, they are prone to clogging over long-term use as impurities accumulate on the surface of the filter elements. Once the filter mechanism becomes clogged, the circulation flow of the cleaning fluid decreases, the cleaning pressure drops, and the cleaning efficiency and effectiveness are affected. To maintain the normal operation of the system, the filter mechanism needs to be disassembled, cleaned, or the filter elements replaced manually and periodically. This cleaning process is not only cumbersome and labor-intensive, but also often requires the CIP cleaning system to be suspended during cleaning, interrupting the normal production cleaning process and reducing overall work efficiency.

[0005] In order to reduce the probability of filter element clogging, reduce the number of manual downtime maintenance, and improve overall work efficiency, we propose a CIP tank cleaning device. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 This utility model provides a technical solution: a CIP tank cleaning device, including a base plate 1, a cleaning liquid tank 2 fixedly installed on the base plate 1, a filter tank 3 fixedly installed on the base plate 1, a number of partitions 16 fixedly connected to the inner wall of the cleaning liquid tank 2, a number of feed inlets 12 and discharge pipes 17 fixedly connected to the cleaning liquid tank 2, a liquid inlet pipe 7 fixedly connected to the top of the filter tank 3, a cleaning component that uses the cleaning liquid in the cleaning liquid tank 2 to clean the tank on the base plate 1, and a filter component that filters the cleaning liquid on the filter tank 3;

[0027] The filter assembly includes a filter plate 23, which is slidably connected to the inner wall of the filter tank 3. A mounting cover 26 is fixedly connected to the bottom of the filter plate 23. Two sets of U-shaped plates 25 are provided on the filter plate 23. The side of the U-shaped plate 25 closest to the mounting cover 26 abuts against the mounting cover 26. Several sets of filter holes are provided on both the filter plate 23 and the U-shaped plates 25. A vibration mechanism that drives the filter plate 23 to vibrate is installed on the filter tank 3. A conveying mechanism that transports impurities on the filter plate 23 out of the filter tank 3 is installed on the filter plate 23. A drive mechanism that drives the vibration mechanism and the conveying mechanism is installed on the filter tank 3.

[0028] The cleaning solution tank 2 is divided into multiple chambers by partition 16, which can be used to hold cleaning solutions such as acid, alkali, and water. During use, the various cleaning solutions are sequentially fed into the tanks to be cleaned via the cleaning assembly. The spraying and circulating action of the cleaning solutions cleans the inner walls of the tanks. After cleaning, the solution flows into the filter tank 3 through the inlet pipe 7 under external power, landing on the filter plate 23. The solution is then filtered through the filter holes on the filter plate 23 and U-shaped plate 25. The filtered solution then flows back into the cleaning solution tank 2 under the action of the cleaning assembly, achieving recycling. During the filtration process, a drive mechanism drives a vibration mechanism, causing the filter plate 23 to vibrate up and down, reducing the probability of clogging the filter holes. Simultaneously, a conveying mechanism transports impurities from the surface of the filter plate 23 out of the filter tank 3, preventing impurities from accumulating on the surface and further preventing clogging of the filter holes. This reduces the probability of filter element clogging, decreases the frequency of manual maintenance, and improves overall work efficiency.

[0029] The conveying mechanism includes a rotating disk 20, which is rotatably connected to the top of the filter plate 23. Several sets of scrapers 19 are provided on the rotating disk 20, and the bottom of the scrapers 19 abuts against the top of the filter plate 23. Two sets of auger blades 27 are rotatably installed on the mounting cover 26. The auger blades 27 are matched with the U-shaped plate 25. Several sets of scraper strips 33 are provided on the auger blades 27. Two sets of conveying ports that match the auger blades 27 are opened on the filter tank 3. Two sets of collection boxes 24 corresponding to the conveying ports are detachably installed on the outer wall of the filter tank 3.

[0030] The drive mechanism drives the rotating disk 20 to rotate, which in turn drives the scraper 19 to rotate, scraping the impurities on the surface of the filter plate 23 into the U-shaped plate 25. At the same time, under the action of the drive mechanism, the auger blades 27 rotate, conveying the impurities in the U-shaped plate 25 out of the filter tank 3 through the conveying port. The impurities and a small amount of cleaning liquid fall into the collection box 24 for collection.

[0031] The vibration mechanism includes a mounting ring 30, which is fixedly connected to the inner wall of the filter tank 3. Several sets of lower protrusions 28 are fixedly connected to the top of the mounting ring 30. A connecting frame 22 is movably connected to the inner wall of the filter tank 3. Several sets of upper protrusions 29 are fixedly connected to the bottom of the connecting frame 22. Both the lower protrusions 28 and the upper protrusions 29 are provided with inclined surfaces, and the lower protrusions 28 and the upper protrusions 29 are matched.

[0032] The drive mechanism includes a motor 8, which is fixedly installed on the top of the filter tank 3. The output end of the motor 8 is fixedly connected to a drive rod 18. A rotating rod 21 is slidably connected to the inner wall of the drive rod 18. A rotating disk 20 is fixedly sleeved on the outside of the rotating rod 21. The rotating rod 21 rotates through the filter plate 23 and the mounting cover 26. The bottom of the rotating rod 21 is fixedly connected to the top of the connecting frame 22. A drive bevel gear 31 is fixedly sleeved on the outside of the rotating rod 21. A driven bevel gear 32 is fixedly connected to the side of the auger blade 27 near the drive bevel gear 31. The driven bevel gear 32 meshes with the drive bevel gear 31.

[0033] When the motor 8 is started, it drives the drive rod 18 to rotate, which in turn drives the rotating rod 21 to rotate. This causes the connecting frame 22 to rotate. Under the action of the lower protrusion 28 and the upper protrusion 29, the connecting frame 22 vibrates up and down while rotating, causing the filter plate 23 to vibrate. At the same time, the rotating rod 21 rotates, causing the rotating disk 20 and the drive bevel gear 31 to rotate. The rotation of the drive bevel gear 31 causes the driven bevel gear 32 to rotate, which in turn drives the auger blades 27 to rotate.

[0034] The cleaning assembly includes a liquid discharge pump 6, which is fixedly installed on the top of the base plate 1. The discharge end of the liquid discharge pump 6 is fixedly connected to a delivery pipe 9, and the suction end of the liquid discharge pump 6 is fixedly connected to a liquid discharge manifold 4. Several sets of liquid discharge pipes 5 are fixedly connected to the cleaning liquid tank 2. The end of the liquid discharge pipe 5 away from the liquid discharge manifold 4 is fixedly connected to the liquid discharge manifold 4. A return mechanism is installed on the base plate 1 to return the filtered cleaning liquid to the cleaning liquid tank 2.

[0035] The cleaning fluid in the cleaning fluid tank 2 is drawn into the discharge pump 6 through the discharge pipe 5 and the discharge manifold 4, and then pumped into the tank to be cleaned through the delivery pipe 9.

[0036] The reflux mechanism includes a reflux pump 15, which is fixedly installed on the top of the base plate 1. The suction end of the reflux pump 15 is fixedly connected to a suction pipe 14. The end of the suction pipe 14 away from the reflux pump 15 is fixedly connected to the filter tank 3. The discharge end of the reflux pump 15 is fixedly connected to a discharge pipe 13. Several sets of reflux pipes 11 are fixedly connected to the cleaning liquid tank 2. The end of the reflux pipe 11 away from the cleaning liquid tank 2 is fixedly connected to a reflux manifold 10. The reflux manifold 10 is fixedly connected to the discharge pipe 13.

[0037] Under the action of the return pump 15, the filtered cleaning liquid flows back to the cleaning liquid tank 2 through the suction pipe 14, the discharge pipe 13, the return manifold 10 and the return pipe 11 in sequence.

[0038] Working principle: The cleaning solution tank 2 is divided into multiple chambers by the partition 16, which can hold cleaning solutions such as acid, alkali and water respectively. These cleaning solutions enter the outlet manifold 4 through the outlet pipe 5, and are pumped into the tank to be cleaned by the outlet pump 6 through the delivery pipe 9 to clean the inner wall of the tank. After cleaning, the cleaning solution flows into the filter tank 3 through the inlet pipe 7 under the action of external power and falls on the filter plate 23. The start motor 8 drives the drive rod 18 to rotate, which in turn drives the rotating rod 21 to rotate. The rotation of the rotating rod 21 causes the connecting frame 22 to rotate. Since the lower protrusion 28 on the mounting ring 30 matches the upper protrusion 29 on the connecting frame 22, the cleaning solution is clean. Both components have inclined surfaces. The connecting frame 22 vibrates up and down while rotating, causing the filter plate 23 to vibrate, reducing the probability of filter hole clogging. Simultaneously, the rotating rod 21 rotates, causing the rotating disk 20 and the driving bevel gear 31 to rotate. The scraper 19 on the rotating disk 20 scrapes impurities from the surface of the filter plate 23 into the U-shaped plate 25. The driving bevel gear 31 meshes with the driven bevel gear 32 on the auger blade 27, causing the auger blade 27 to rotate and send the impurities in the U-shaped plate 25 into the collection box 24 through the conveying port, further preventing filter hole clogging. This reduces the probability of filter element clogging, decreases the number of manual maintenance shutdowns, and improves overall work efficiency. The filtered cleaning liquid, under the action of the return pump 15, flows back to the cleaning liquid tank 2 sequentially through the suction pipe 14, discharge pipe 13, return manifold 10, and return pipe 11, realizing the recycling of the cleaning liquid.
