[0002] Saccharin sodium is an organic compound and a food additive. It is a commonly used synthetic sweetener in the food industry and has the longest usage history, but it is also the most controversial synthetic sweetener. Saccharin sodium needs to be purified by a concentrator during production.

[0003] Existing public patent: CN202321722048.4, a concentrator for saccharin sodium extraction. The arc-shaped scraping rod scrapes off the saccharin sodium adhering to the bottom of the concentration tank and then gathers it towards the center and discharges it. This method can fully stir the saccharin sodium evenly during processing, and when discharging, the saccharin sodium adhering to the inner wall and bottom of the concentration tank can be scraped clean before discharging, greatly reducing the residue of saccharin sodium in the concentration tank, thus saving resources and also saving the labor of manual cleaning.

[0074] Among them, the front end of the sliding rod 10 is slidably connected to the sliding ring pipe 21;

[0077] Among them, the first fixing rod 15 is slidably connected to the right side surface of the mounting block 7, and the first fixing rod 15 slidably penetrates into the fixing groove 8.

[0078] Furthermore, the first fixing rod 15 and the second fixing rod 16 are arranged at a ninety-degree angle with the support rod 9 as the center;

[0079] Among them, both the first fixing rod 15 and the second fixing rod 16 are slidably connected to the through hole 25;

[0080] Among them, the first fixing block 11 is fixedly connected to the right end of the first fixing rod 15;

[0081] Among them, the second fixing block 12 is fixedly connected to the right end of the second fixing rod 16;

[0082] Among them, the first spring 13 is fixedly connected between the second fixing block 12 and the mounting block 7, and the first spring 13 is slidably sleeved on the outer surface of the second fixing rod 16;

[0083] Among them, the second spring 14 is fixedly connected between the first fixing block 11 and the mounting block 7, and the second spring 14 is slidably sleeved on the outer surface of the first fixing rod 15.

[0084] Furthermore, the outer wall of the concentration tank 3 is fixedly connected with a heating barrel, a connecting nozzle, etc. A valve is provided on the outlet pipe 4. The concentration tank 3 is the prior art in an existing publicly patented concentration kettle for saccharin sodium extraction: CN202321722048.4, which will not be elaborated here;

[0085] Furthermore, during use, the first fixing block 11 and the second fixing block 12 can be pulled, driving the first fixing rod 15 or the second fixing rod 16 to move out of the through hole 25. During this process, the first spring 13 and the second spring 14 are also stretched. Then, the sliding rod 10 is rotated to a vertical state. At this time, the pulling of the first fixing block 11 and the second fixing block 12 is released. Under the action of the elastic force released by the first spring 13 and the second spring 14, the first spring 13 drives the second fixing rod 16 to move into the through hole 25, thereby positioning the sliding rod 10 and making the sliding rod 10 positioned in a vertical state;

[0086] As described above, at this time, the motor 6 is started. The motor 6 starts to drive the rotating shaft 5 to rotate, and then drives the mounting block 7 to rotate accordingly. Since the sliding rod 10 is in a vertical state, the sliding rod 10 does not contact the sliding ring pipe 21. Therefore, when the motor 6 is started at this time, it drives the stirring rod 17 and the scraping plate 19 to rotate. On the one hand, it stirs the lower side of the concentration tank 3, so that the saccharin sodium can be fully stirred evenly during processing. On the other hand, the scraping plate 19 can scrape the saccharin sodium on the inner wall and bottom cloth of the lower side of the concentration tank 3, which can reduce the residue of saccharin sodium in the concentration tank 3. Thus, while ensuring the extraction and processing effect of saccharin sodium, it can avoid waste of materials, thereby increasing the practicality of the concentration kettle.

[0087] As described above, when in use, pull the first fixing block 11 and the second fixing block 12, and then rotate the sliding rod 10 to a horizontal state. At this time, release the pulling of the first fixing block 11 and the second fixing block 12, so that the first fixing rod 15 moves into the through hole 25. At this time, position the horizontal state of the sliding rod 10 so that the sliding rod 10 is positioned to the horizontal state. At this time, the lower surface of the sliding rod 10 should be slidably connected to the upper surface of the lower part of the sliding ring tube 21. At this time, start the motor 6. The start of the motor 6 drives the mounting block 7 to rotate, and then drives the sliding rod 10 to rotate. During the rotation of the sliding rod 10, the sliding rod 10 will move up and down along the undulating track of the sliding ring tube 21. When the sliding rod 10 moves upward, it drives the connecting plate 20, the rotating shaft 5, the positioning rod 23, etc. to move up and down. The upward movement of the positioning rod 23 stretches the positioning spring 24. When the sliding rod 10 moves downward, under the action of the released elastic force of the positioning spring 24, it drives the connecting plate 20, the rotating shaft 5, the positioning rod 23, etc. to move downward. During this process, the stirring rod 17 and the scraping plate 19 are synchronously driven to move up and down. Therefore, when the motor 6 is started, it can not only drive the stirring rod 17 and the scraping plate 19 to rotate, but also drive the stirring rod 17 and the scraping plate 19 to move up and down. Thus, the stirring range of saccharin sodium in the concentration tank 3 is improved, and the extraction efficiency and extraction effect of the concentration kettle are improved. On the other hand, the scraping range of saccharin sodium in the concentration tank 3 can be improved, so as to ensure the cleaning effect of the inner wall of the concentration tank 3, avoid waste of materials, and increase the practicability of the concentration kettle.

[0088] Further, in this solution, by setting the stirring and scraping mechanism, only one motor is needed to drive the up and down movement and rotation of the stirring rod 17 and the scraping plate 19, without using two motors, which can save electricity and reduce the production cost of the concentration kettle, and thus increase the practicability of the concentration kettle.

[0089] Further, in this solution, the elastic force of the positioning spring 24 is relatively large. The positioning spring 24 plays a role in making the sliding rod 10 adhere to the sliding ring tube 21 during the up and down movement of the sliding rod 10, so as to ensure the stability of the up and down movement of the sliding rod 10 and avoid jamming when the sliding rod 10 moves downward.

[0090] Working principle: When the device is in use, when in use, the first fixing block 11 and the second fixing block 12 can be pulled, driving the first fixing rod 15 or the second fixing rod 16 to move out of the through hole 25. During this process, the first spring 13 and the second spring 14 are also stretched. Then rotate the sliding rod 10 to a vertical state. At this time, release the pulling of the first fixing block 11 and the second fixing block 12. Under the action of the released elastic force of the first spring 13 and the second spring 14, the first spring 13 drives the second fixing rod 16 to move into the through hole 25, thereby positioning the sliding rod 10 so that the sliding rod 10 is positioned to the vertical state;

[0091] As described above, at this time, the motor 6 is started. The start of the motor 6 drives the rotating shaft 5 to rotate, and then drives the mounting block 7 to rotate. Since the sliding rod 10 is in a vertical state, the sliding rod 10 does not contact the sliding ring pipe 21. Then, when the motor 6 is started, the stirring rod 17 and the scraper 19 are driven to rotate. On the one hand, the lower side of the concentration tank 3 is stirred, so that the saccharin sodium can be fully stirred evenly during processing. On the other hand, the scraper 19 can scrape the saccharin sodium on the inner wall and the bottom cloth of the lower side of the concentration tank 3, which can reduce the residue of saccharin sodium in the concentration tank 3. Thus, while ensuring the extraction and processing effect of saccharin sodium, material waste can be avoided, and the practicability of the concentration kettle is increased.

[0092] As described above, when in use, the first fixing block 11 and the second fixing block 12 are pulled, and then the sliding rod 10 is rotated to a horizontal state. At this time, the pulling of the first fixing block 11 and the second fixing block 12 is released, so that the first fixing rod 15 moves into the through hole 25, and the horizontal state of the sliding rod 10 is positioned at this time, so that the sliding rod 10 is positioned in the horizontal state. At this time, the lower surface of the sliding rod 10 should be slidably connected to the upper surface of the lower part of the sliding ring pipe 21. At this time, the motor 6 is started. The start of the motor 6 drives the mounting block 7 to rotate, and then drives the sliding rod 10 to rotate. During the rotation of the sliding rod 10, the sliding rod 10 will move up and down along the undulating track of the sliding ring pipe 21. When the sliding rod 10 moves upward, it drives the connecting plate 20, the rotating shaft 5, the positioning rod 23, etc. to move up and down. When the positioning rod 23 moves upward, the positioning spring 24 is stretched. When the sliding rod 10 moves downward, under the action of the released elastic force of the positioning spring 24, it drives the connecting plate 20, the rotating shaft 5, the positioning rod 23, etc. to move downward. During this process, the stirring rod 17 and the scraper 19 are synchronously driven to move up and down. Therefore, when the motor 6 is started, it can not only drive the stirring rod 17 and the scraper 19 to rotate, but also drive the stirring rod 17 and the scraper 19 to move up and down. Thus, the stirring range of the saccharin sodium in the concentration tank 3 is increased, and the extraction efficiency and extraction effect of the concentration kettle are improved. On the other hand, the scraping range of the saccharin sodium in the concentration tank 3 can be increased, so as to ensure the cleaning effect of the inner wall of the concentration tank 3, avoid material waste, and increase the practicability of the concentration kettle.

[0093] Furthermore, in this solution, by setting the stirring and scraping mechanism, only one motor is needed to drive the up and down movement and rotation of the stirring rod 17 and the scraper 19, without using two motors. While saving electricity, the production cost of the concentration kettle can be reduced, and the practicability of the concentration kettle is increased.

[0094] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
