[0024] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] See also Figures 1 to 8 The utility model provides a technical solution: a distillation device for the production and purification of sweeteners, comprising a tank body 1, a stirring rod 2 is installed inside the tank body 1, a connecting plate 3 is installed at the bottom end of the stirring rod 2, a scraper 4 is installed at the bottom end of the connecting plate 3, the outer side of the scraper 4 is in contact with the lower side of the inner wall of the tank body 1, connecting rods 5 are hinged on both the front and rear sides of the top of the connecting plate 3, the outer front and rear sides of the stirring rod 2 are fixedly connected to the limiting block 7, the outer side of the limiting block 7 is slidably connected to the slider 6, the slider 6 is slidably connected to the outside of the stirring rod 2, and the other ends of the two connecting rods 5 are hinged on the front and rear sides of the slider 6 respectively.

[0027] The top end of the stirring rod 2 is installed on the output end of the motor. By starting the motor, the stirring rod 2 can be driven to stir the raw materials inside the tank body 1, and then the stirring rod 2 can drive the scraper 4 to scrape the lower side of the inner wall of the tank body 1 through the connecting plate 3, so that the residual material will not adhere to the lower side of the inner wall of the tank body 1, making it easier for workers to clean, thereby reducing the labor intensity of workers.

[0028] Embodiment 2

[0029] On the basis of Example 1, in order to realize automatic opening and closing of the scraper 4, the left and right sides of the stirring rod 2 are fixedly connected with a sleeve 9, and a mounting groove 10 is opened inside the sleeve 9. A tension spring 11 is fixedly connected to the upper side of the inner wall of the mounting groove 10, and the bottom end of the tension spring 11 is fixedly connected to a mounting block 12, and the bottom end of the mounting block 12 is fixedly connected to a pull rod 13. The outside of the pull rod 13 is slidably connected to the inside of the mounting groove 10, and the bottom ends of the two pull rods 13 are respectively fixedly connected to the left and right sides of the top of the slider 6, and two blocks 8 are respectively fixedly connected to the upper and lower sides of the stirring rod 2. The four blocks 8 are distributed in a rectangular shape, and the bottom end of the sleeve 9 is fixedly connected to the top of the upper block 8.

[0030] When the stirring rod 2 is placed inside the tank body 1 from top to bottom, the retracted scraper 4 will first contact the inner bottom wall of the tank body 1, and then when the stirring rod 2 continues to move downward, the contact points of the two scrapers 4 with the tank body 1 will move toward the adjacent side, so that the other end of the scraper 4 can be unfolded. At this time, the connecting plate 3 will follow the movement of the scraper 4, so that the connecting plate 3 can pull the lower side of the connecting rod 5 to move downward, and then the other end of the connecting rod 5 can drive the slider 6 to slide downward, so that the slider 6 can pull the pull rod 13 to move downward, and then the mounting block 12 can deform by pulling the tension spring 11 through the mounting block 12. When the bottom surface of the scraper 4 is completely in contact with the inner bottom wall of the tank body 1, the lower side of the slider 6 can be in contact with the upper side of the lower side stopper 8, so that the position of the scraper 4 can be fixed, so that the scraper 4 can stably scrape the lower side of the inner wall of the tank body 1. When cleaning the residual material inside the tank body 1, the stirring rod 2 is pulled upward so that the scraper 4 as a whole is no longer in contact with the lower side of the inner wall of the tank body 1. At this time, the tension spring 11 can perform a reset movement, so that the tension spring 11 can pull the pull rod 13 upward through the mounting block 12, and then the pull rod 13 can pull the slider 6 to move upward, so that the slider 6 can pull the other end of the connecting rod 5 downward through the connection with the connecting rod 5, and at the same time, the lower side of the connecting rod 5 can be retracted inward, so that the lower side of the connecting rod 5 can drive the connecting plate 3 and the scraper 4 to be retracted. When the top end of the slider 6 is in contact with the lower side of the upper stopper 8, the lateral distance of the scraper 4 is smaller than the aperture of the tank mouth of the tank body 1, and then when the stirring rod 2 is pulled out of the tank body 1, the scraper 4 can also follow the stirring rod 2 to leave the tank body 1, and the scraper 4 will not affect the normal cleaning of the inside of the tank body 1.

[0031] Embodiment 3

[0032] On the basis of the second embodiment, in order to realize the replacement of the damaged scraper 4, a plurality of card blocks 14 are fixedly connected inside the connecting plate 3, a plurality of placement grooves 15 are opened inside the bottom end of the connecting plate 3, and a card block 2 16 is inserted inside the placement groove 15, and the bottom ends of every two card blocks 2 16 are respectively fixedly connected to the front and rear sides of the top ends of the two scrapers 4, and a rubber strip 17 is respectively fixedly connected between the card block 2 16 and the card block 1 14. The connecting plate 3 is designed in three sections, and the connecting plates 3 of the front and rear sections are symmetrically distributed with the middle connecting plate 3 as the center, wherein two card blocks 14 are respectively fixedly connected to the inside of the front and rear connecting plates 3, and the other two card blocks 14 are respectively fixedly connected to the front and rear sides of the middle connecting plate 3, and the card block 14, the placement groove 15 and the card block 2 16 match, and the two middle card blocks 14 are respectively slidably connected to the inside of the placement grooves 15 at the corresponding positions.

[0033] When the scraper 4 is in the state of being stored, the inner block 2 16 is no longer in contact with the block 1 14, and the rubber strip 17 inside it is also separated. At this time, the scraper 4 is pulled outward, so that the scraper 4 can drive the block 2 16 to move outward, thereby making the block 2 16 separate from the block 1 14, and making the block 2 16 detach from the inside of the placement groove 15, so that the scraper 4 can be easily removed, and vice versa, it can be easily installed. When the scraper 4 is in the state of being fully expanded, the inner block 2 16 is in contact with the block 1 14, and the rubber strip 17 inside it is engaged, and is used in conjunction with the outer block 1 14, the block 2 16 and the rubber strip 17, so that the scraper 4 can be stably installed on the lower side of the connecting plate 3, so that the scraper 4 will not be separated from the connecting plate 3 during the scraping operation, thereby making the cleaning stability higher, and thus will not affect the normal stirring of the inside of the tank body 1 by the stirring rod 2.

[0034] In actual use, by installing the stirring rod 2 inside the tank body 1, the lower side of the stirring rod 2 can fit with the inner bottom wall of the tank body 1. During this process, the lower side of the scraper 4 will use the inner bottom wall of the tank body 1 as a fulcrum and slide to the nearby side, so that the other end of the scraper 4 can pull the lower side of the connecting rod 5 to slide downward, so that the upper side of the connecting rod 5 can pull the sliding block 6 to slide downward. When the overall bottom surface of the scraper 4 fits with the lower side of the inner wall of the tank body 1, the sliding block 6 fits with the top of the lower side block 8. Then, when the stirring rod 2 is stirring, the stirring rod 2 can drive the scraper 4 to clean the lower side of the inner wall of the tank body 1, so that the residual material will not adhere to the lower side of the inner wall of the tank body 1, thereby greatly reducing the labor intensity of the workers, thereby reducing the labor cost.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
