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 mostly use chemical cleaning or room temperature liquid flushing. Although chemical cleaning can remove crystallization dirt, it often relies on a large amount of chemical cleaning agents, which is not only costly, but also easy to remain in the equipment, which has a serious impact on the quality of subsequent crystallization products. Especially in industries that require high-purity products such as food, pharmaceuticals, and electronics, chemical residues may cause unqualified products or even endanger human health.

[0003] The normal temperature liquid flushing method is limited by the liquid temperature. For some stubborn dirt generated by the high temperature crystallization process, the cleaning effect is extremely limited. These dirt are difficult to soften and dissolve at room temperature and tend to accumulate on the inner surface of the crystallizer, resulting in problems such as reduced heat transfer efficiency of the crystallizer, unstable crystallization process, and product quality fluctuations. At the same time, frequent and inefficient cleaning will increase equipment downtime, reduce production efficiency, and increase the company's operating costs; 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 thermal enthalpy value, can effectively solve the cleaning problem of stubborn crystallization dirt due to its high temperature characteristics. 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 development and application of crystallizer backwash cleaning devices that use steam for high-temperature cleaning.

[0004] Chinese patent (publication number CN113500056A), the 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 extraction pipeline inserted into the bottom of the cleaning liquid tank, and the other end of the pneumatic diaphragm pump is provided with a diaphragm pump liquid outlet pipeline connected to the water inlet manifold. The water inlet manifold diverts the cleaning liquid in the diaphragm pump outlet pipeline 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. The 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.

[0005] 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 dealing with stubborn high-temperature crystallized materials and may have 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 the corners, but it is not effective for non-high-temperature dirt such as grease.

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 penetrated inside the second connecting circular tube 17. A second abutting ball 25 is fixedly connected to the bottom of the first connecting column 20. 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 pads are pasted on the outer walls of the second blocking plate 21 and the first blocking plate 18. The rubber sealing pad can enhance the sealing between 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. See also Figure 8 , Fig. 9The rotating mechanism 201 includes a telescopic tube 33, the elastic coefficient of the telescopic tube 33 is greater than all the second elastic springs 24, the telescopic tube 33 is fixedly connected to the bottom of the rotating barrel 16, and the telescopic tube 33 is sleeved on the outer wall of the second connecting column 28. Specifically, a sliding opening is opened at the output end of the telescopic tube 33, and the inner wall of the sliding opening abuts against the outer wall of the second connecting column 28. The outer wall of the second connecting column 28 is coated with lubricating oil. When the telescopic tube 33 is extended, the sliding opening at the output end of the telescopic tube 33 will slide on the outer wall of the second connecting column 28. The second connecting column 28 can limit the telescopic tube 33 and also has a guiding function, thereby improving the stability of the output end of the telescopic tube 33 when extending. The lubricating oil can also reduce the friction between the sliding opening and the second connecting column 28, thereby extending the service life of the second connecting column 28. The outer wall of the telescopic tube 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 a plurality of The stem connecting arm 30 is fixedly connected, and a plurality of 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 with the telescopic tube 33, and the bottom of the telescopic tube 33 is fixedly connected with the second matching circular plate 32, and the second matching circular plate 32 is fixedly connected between the first matching circular plate 31 through a plurality of pull ropes 34. The pull ropes 34 are made of metal material, and 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 with a connecting ring 35, and the bottom of the connecting ring 35 is fixedly connected with a plurality of abutting telescopic rods 36, and the bottom of the abutting telescopic rod 36 is movably installed with a first abutting ball, and the first abutting ball is spherical. The connecting ring 35 is located above the first matching circular plate 31. A plurality of ball grooves 37 are also opened at the upper end of the first matching circular plate 31, and the inner wall of the ball groove 37 is spherical, and each first abutting ball is clamped in the corresponding inner wall of the ball groove 37; Specifically, when the telescopic tube 33 expands and stretches inside, the first matching circular plate 31 will be pulled and rotated through the pull rope 34, and the first matching circular plate 31 will rotate the rotating frame 29 through the connecting arm 30. Subsequently, the first matching circular plate 31 will rotate 360 ​​degrees. When the first matching circular plate 31 rotates, the abutting telescopic rod 36 will drive 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 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. 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, and 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 with a second matching plate 38, and the second matching plate 38 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, which can 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 arranged inside the first connecting circular tube 11, and the ball diameter of the third abutting ball 39 is smaller than The outer wall of the third abutment ball 39 does not abut against the inner wall of the first connecting circular tube 11, and there is still a large gap. The third abutment 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 abutment ball 39 abuts against the second abutment 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 abutment ball 25 will drive the first connecting column 20 to move upward.

[0026] The working principle of the present invention is: When it is necessary to clean the inner wall of the first connecting pipe 2 connected to the crystallizer, the gas-liquid separation tank, etc., the heating copper tube 10 is started, and the heating copper tube 10 heats and boils the water in the rotating barrel 16. When the water in the rotating barrel 16 boils and generates 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 becomes longer. At this time, more steam can be stored in the moving barrel 27. When the moving barrel 27 and the rotating barrel 1 When the air pressure inside 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 the first matching circular plate 31 to rotate. 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, 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 internal steam into the recoil cleaning tube 4. The steam inside the recoil cleaning tube 4 will flow into the first connecting tube 2, and 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 the steam from leaking from the gap between the second connecting tube 17 and the first connecting tube 11. 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 moving barrel 27, the abutting telescopic rod 36 will drive 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 rotation force of the first matching circular plate 31 is greater than the abutment 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 moving barrels 27 through the connecting arm 30. When the telescopic tube 33 continues to extend, all the moving barrels 27 rotate. When the steam inside all the moving barrels 27 is released, the disinfection is completed. When the backwash cleaning pipe 4 is sterilized at high temperature, the electric ball valve inside the tap water connecting pipe 3 needs to be closed. After the sterilization 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, and tap water is passed from the inside of the tap water connecting pipe 3 to clean the inside of the backwash cleaning pipe 4. 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 shrink, 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, the rotating frame 29 will reset and rotate, and 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 reset.
