Description

Technical Field

[0001] The invention relates to the technical field of crystallizer cleaning, in particular to a backwash cleaning device used after crystallization. Background Art

[0002] Traditional crystallizer cleaning methods often rely on chemical cleaning or room-temperature liquid flushing. While chemical cleaning can remove crystallization contamination, it often relies on large amounts of chemical cleaning agents, which is not only costly but also prone to leaving residues within the equipment, seriously impacting the quality of subsequent crystallized products. This is especially true in industries requiring high-purity products, such as food, pharmaceuticals, and electronics. Chemical residues can lead to substandard products and even pose a health risk.

[0003] The room-temperature liquid flushing method is limited by the liquid temperature. It has a very limited cleaning effect on stubborn dirt generated during high-temperature crystallization processes. This dirt is difficult to soften and dissolve at room temperature and tends to accumulate on the inner surface of the crystallizer, leading to problems such as reduced heat transfer efficiency, unstable crystallization process, and fluctuating product quality. Furthermore, frequent and inefficient cleaning increases equipment downtime, reduces production efficiency, and increases the company's operating costs.

[0004] With the continuous improvement of industrial production requirements for product quality, production efficiency and environmental protection, there is an urgent need for a more efficient, environmentally friendly crystallizer cleaning technology that can ensure product quality. Steam, as a widely used medium with high enthalpy value, has high temperature characteristics that can effectively solve the cleaning problem of stubborn crystallization dirt. Steam is relatively pure and will not introduce chemical impurities. While meeting the requirements of efficient cleaning, it conforms to the development trend of green environmental protection and high-quality production. This has prompted the research and development and application of crystallizer backwash cleaning devices that use steam for high-temperature cleaning.

[0005] Chinese patent (publication number CN113500056A), this patented technology discloses a crystallizer cleaning device, including a cleaning liquid tank, a pneumatic diaphragm pump, a water inlet manifold, and a water outlet manifold. One end of the pneumatic diaphragm pump is provided with a diaphragm pump liquid suction pipe inserted into the bottom of the cleaning liquid tank, and the other end of the pneumatic diaphragm pump is provided with a diaphragm pump outlet pipe connected to the water inlet manifold. The water inlet manifold diverts the cleaning liquid in the diaphragm pump outlet pipe into multiple crystallizers, and the water outlet manifold merges the cleaning liquids in multiple crystallizers and introduces them into the cleaning liquid tank. A cleaning liquid circulation channel is formed between the cleaning liquid tank, the pneumatic diaphragm pump, the water inlet manifold, the crystallizer, and the water outlet manifold. This invention can connect the crystallizer to the cleaning liquid circulation channel, realize rapid cleaning of the crystallizer, save the steps of manually disassembling and decomposing the crystallizer for cleaning, and reduce the labor intensity of workers.

[0006] According to the above scheme, when cleaning the crystallizer, it is only disinfected by cleaning liquid. Cleaning with cleaning liquid is based on the principle of combining chemistry and physics. It is effective for specific dirt, but it has limitations in treating stubborn high-temperature crystallized materials and may cause environmental and safety issues. High-temperature steam cleaning mainly relies on physical action. It is efficient and can remove high-temperature crystallized dirt deep into corners, but it is not effective for non-high-temperature dirt such as grease. For this reason, we have proposed a backwash cleaning device for use after crystallization. Summary of the Invention

[0038] Example 2: Please refer to Figure 4 、 Figure 6 、 Figure 7The high-temperature disinfection mechanism 101 includes a rotating frame 29 with a reset function, and the rotating frame 29 is rotatably connected to the bottom of the rotating barrel 16 through a rotating shaft. The rotating frame 29 and the rotating barrel 16 are connected by a first reset torsion spring. The outer wall of the rotating barrel 16 is fixedly connected to a plurality of movable barrels 27. The plurality of movable barrels 27 are circumferentially distributed on the outer wall of the rotating barrel 16. The inner wall of the movable barrel 27 is fixedly connected to two second elastic springs 24. The two second elastic springs 24 are symmetrically distributed front and back inside the movable barrel 27. The second elastic spring 24 can drive the movable barrel 27 to quickly reset. The upper end of the rotating barrel 16 is rotatably connected to a rotating annular plate 15. The upper end of the rotating annular plate 15 is fixedly connected to a plurality of matching tubes 14, and the matching tubes 14 are connected to the rotating barrel 16. The end of each matching tube 14 away from the rotating annular plate 15 is arranged inside the corresponding movable barrel 27.

A first elastic spring 23 is fixedly connected between the inner walls of the barrel 27, and the first elastic spring 23 is sleeved on the outer wall of the first connecting column 20. The upper end of the first connecting column 20 is fixedly connected to the connecting telescopic rod 19, and the upper end of the connecting telescopic rod 19 is fixedly connected to the first blocking plate 18. The diameter of the first blocking plate 18 is larger than the diameter of the matching tube 14. The bottom of the first connecting column 20 is fixedly connected to the second blocking plate 21. The bottom of the movable barrel 27 is fixedly connected to the second connecting circular tube 17. The outer wall of the first connecting column 20 is passed through the interior of the second connecting circular tube 17. The bottom of the first connecting column 20 is fixedly connected to the second abutting ball 25. The end of the second connecting circular tube 17 away from the movable barrel 27 is fixedly connected to the first matching plate 26. The bottom of the second blocking plate 21 abuts against the upper end of the second connecting circular tube 17. Rubber sealing gaskets are pasted on the outer walls of the second blocking plate 21 and the first blocking plate 18. The rubber sealing gasket can enhance the sealing performance of the first blocking plate 18 and the matching tube 14 and the sealing between the second blocking plate 21 and the second connecting circular tube 17.

[0039] See also Figure 8 、 Figure 9The cam 33 is fixedly connected to the bottom of the rotating drum 16, and the cam 33 is sleeved on the outer wall of the second connecting post 28. Specifically, a sliding opening is opened at the output end of the cam 33, and the inner wall of the sliding opening abuts against the outer wall of the second connecting post 28. The outer wall of the second connecting post 28 is coated with lubricating oil. When the cam 33 is extended, the sliding opening at the output end of the cam 33 slides on the outer wall of the second connecting post 28. The second connecting post 28 can limit the cam 33 and also has a guiding function to improve the stability of the output end of the cam 33 when it is extended. The lubricating oil can also reduce the friction between the sliding opening and the second connecting post 28, thereby extending the service life of the second connecting post 28. The outer wall of the cam 33 is fixedly connected to the first matching circular plate 31. The first matching circular plate 31 and the rotating frame 29 are connected by some The stem connecting arm 30 is fixedly connected, and several connecting arms 30 are distributed in a circle between the first matching circular plate 31 and the rotating frame 29. The output end of the telescopic tube 33 is fixedly connected to the telescopic tube 33, and the bottom of the telescopic tube 33 is fixedly connected to the second matching circular plate 32, and the second matching circular plate 32 is fixedly connected to the first matching circular plate 31 through several pull ropes 34. The pull ropes 34 are made of metal. The metal material has good corrosion resistance and high temperature resistance and is durable. The outer wall of the telescopic tube 33 is also fixedly connected to a connecting ring 35, and the bottom of the connecting ring 35 is fixedly connected to several abutting telescopic rods 36. A first abutting ball is movably installed at the bottom of the abutting telescopic rod 36. The first abutting ball is spherical. The connecting ring 35 is located above the first matching circular plate 31. The upper end of the first matching circular plate 31 is also provided with several ball grooves 37, and the inner wall of the ball groove 37 is spherical. Each first abutting ball is clamped in the corresponding inner wall of the ball groove 37.

[0040] Specifically, when the telescopic tube 33 expands and stretches, the first matching circular plate 31 is pulled and rotated by the pull rope 34, and the first matching circular plate 31 rotates the rotating frame 29 through the connecting arm 30. Subsequently, the first matching circular plate 31 rotates 360 degrees. When the first matching circular plate 31 rotates, the abutting telescopic rod 36 drives the first abutting ball to be engaged with the inner wall of the ball groove 37, which causes the first matching circular plate 31 to not rotate directly. When the rotation force of the first matching circular plate 31 is greater than the abutting force between the first abutting ball and the ball groove 37, the first matching circular plate 31 can rotate, thereby slowing down the rotation speed of the first matching circular plate 31.

[0041] See also Figure 2 - Figure 4 、 Figure 7The docking mechanism 301 includes a first connecting circular tube 11, which is fixedly connected to the upper end of the mounting base 9. The bottom of the first connecting circular tube 11 is fixedly connected to the backwash cleaning pipe 4. The upper end of the first connecting circular tube 11 is fixedly connected to a second matching plate 38, which is adapted to the first matching plate 26. The outer walls of the second matching plate 38 and the first matching plate 26 are both pasted with rubber sheets to enhance the sealing between the first matching plate 26 and the second matching plate 38. A third abutting ball 39 with a reset function is provided inside the first connecting circular tube 11. The ball diameter of the third abutting ball 39 is smaller than The inner wall diameter of the first connecting circular tube 11, the outer wall of the third abutting ball 39 does not abut against the inner wall of the first connecting circular tube 11, and there is a large gap. The third abutting ball 39 is fixedly connected to the inner wall of the first connecting circular tube 11 through a reset elastic telescopic rod. It is worth noting that the elastic coefficient of the reset elastic telescopic rod is higher than the elastic coefficient of the first elastic spring 23. Therefore, when the third abutting ball 39 abuts against the second abutting ball 25, since the elastic coefficient of the reset elastic telescopic rod is higher than the elastic coefficient of the first elastic spring 23, the second abutting ball 25 will drive the first connecting column 20 to move upward.

[0042] The working principle of the present invention is:

[0043] When it is necessary to clean the inner wall of the first connecting pipe 2 connected to the crystallizer, gas-liquid separation tank, etc., the heating copper pipe 10 is started. The heating copper pipe 10 will heat and boil the water in the rotating barrel 16. When the water in the rotating barrel 16 boils and produces a large amount of steam, the steam will enter the corresponding moving barrel 27 along the matching pipe 14. At this time, the air pressure in the moving barrel 27 becomes larger, and the moving barrel 27 will become longer. At this time, more steam can be stored in the moving barrel 27. When the moving barrel 27 and the rotating barrel 1 are connected, the steam will be heated and boiled. 6 When the internal air pressure reaches the limit, the telescopic tube 33 will be extended, and the telescopic tube 33 will drive the second matching circular plate 32 to move downward. The pull rope 34 will pull and rotate the first matching circular plate 31. The first matching circular plate 31 will rotate the rotating frame 29 through the connecting arm 30. The rotating frame 29 will drive all the moving barrels 27 to rotate. When one of the moving barrels 27 moves to the top of the first connecting circular tube 11, the second matching plate 38 will first abut against the first matching plate 26 during the movement. At this time, the first matching plate When the third abutting ball 39 abuts against the first matching plate 26, it will shrink toward the inner wall of the first connecting tube 11. When the third abutting ball 39 abuts against the first matching plate 26, the third abutting ball 39 will push the first matching plate 26, and the first matching plate 26 will drive the first connecting column 20 to move upward. At this time, the second blocking plate 21 will be separated from the abutment with the second connecting tube 17, and the first connecting column 20 will continue to drive the connecting telescopic rod 19 and the first blocking plate 18 to move upward. The blocking plate 18 blocks the matching tube 14 so that the steam inside the rotating barrel 16 cannot enter the movable barrel 27. At this time, the second elastic spring 24 will drive the movable barrel 27 to shrink rapidly, pushing the steam inside into the backwash cleaning tube 4. The steam inside the backwash cleaning tube 4 will flow into the first connecting tube 2, and the interior of the first connecting tube 2 can be cleaned and sterilized at high temperature. The first matching plate 26 and the second matching plate 38 can prevent steam from leaking from the gap between the second connecting tube 17 and the first connecting tube 11.

[0044] In order to prevent the second matching plate 38 from abutting against the first matching plate 26 for too short a time, resulting in the inability to completely discharge the steam inside the movable barrel 27, the abutting telescopic rod 36 drives the first abutting ball to be clamped in the inner wall of the ball groove 37, which will cause the first matching circular plate 31 to not rotate directly. When the rotating force of the first matching circular plate 31 is greater than the abutting force between the first abutting ball and the ball groove 37, the first matching circular plate 31 can rotate, slowing down the rotation speed of the first matching circular plate 31. In this way, the first matching circular plate 31 will slow down the movement speed of all the movable barrels 27 through the connecting arm 30. When the telescopic tube 33 continues to extend, all the movable barrels 27 rotate. When the steam inside all the movable barrels 27 is completely released, the disinfection is completed.

[0045] During the high-temperature disinfection of the backwash cleaning pipe 4, the electric ball valve inside the tap water connecting pipe 3 needs to be closed. After the disinfection is completed, the electric ball valve needs to be opened, and the upper end of the second matching plate 38 needs to be sealed with tape. Then, tap water is passed from the inside of the tap water connecting pipe 3 to clean the inside of the backwash cleaning pipe 4 again.

[0046] After the disinfection is completed, the heating of the inside of the rotating barrel 16 is stopped. After the water inside the rotating barrel 16 cools down, the second elastic spring 24 will drive the movable barrel 27 to reset and contract, and the first elastic spring 23 will also drive the first connecting column 20 to reset, the second blocking plate 21 will abut against the second connecting circular tube 17, and the rotating frame 29 will reset and rotate. The rotating frame 29 will also drive the first matching circular plate 31 to reset and rotate through the connecting arm 30. At this time, all the pull ropes 34 will be reset.

[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
