[0002] As the name implies, a concentration kettle is a kettle body used for concentrating solutions and is used in fields such as chemical industry, pharmacy, and food. Generally, a concentration kettle includes a kettle body and a coil pipe for heating the outer wall of the kettle body. According to actual situations, a negative pressure pipe can also be connected to the top of the kettle body, and then the inside of the kettle body is in a negative pressure state during the concentration process, while the external coil pipe is heated, so as to accelerate the volatilization of the solvent in the kettle body and concentrate a relatively dilute solution into a relatively concentrated solution, or concentrate the solution into a paste.

[0003] After some materials are concentrated to form a liquid or paste with a relatively high concentration, when the materials are discharged from the kettle body, it is still easy to have a lot of residue on the inner wall of the kettle body, and even workers need to enter the kettle body to manually scrape the entire inner wall for cleaning, and the operation effect is poor. Summary of the Invention

[0010] A stirring and scraping auger, the stirring and scraping auger is in a spiral shape, and the stirring and scraping auger is fixedly connected to the free ends of all the support rods;

[0011] The stirring and scraping auger includes a stirring state and a scraping state;

[0012] When the stirring and scraping auger is in the stirring state, there is a separated state between the stirring and scraping auger and the inner wall of the accommodating part;

[0013] When the stirring and scraping auger is in the scraping state, the stirring and scraping auger is movably attached to the inner wall of the accommodating part and drives the material located on the inner wall of the accommodating part downward.

[0018] A second through hole communicating with the first through hole is vertically penetrated through the support column. The bottom of the output shaft and the top of the stirring rod are both attached to the inner wall of the second through hole. A circular ring-shaped annular groove and a first spiral groove and a second spiral groove communicating with the bottom of the annular groove are horizontally opened on the inner wall of the second through hole. The pitches of the first spiral groove and the second spiral groove are equal and the spiral directions are the same. The connection of the first spiral groove and the annular groove is at one end of the annular groove, and the connection of the second spiral groove and the annular groove is at the other end of the annular groove;

[0019] The first synchronization rod is vertically connected to the bottom of the output shaft, and the cross-section of the first synchronization rod is rectangular.

Two acting parts are arranged at the same height on the outer wall of the stirring rod, and the two acting parts are located on both sides of the stirring rod.

[0020] When the stirring and scraping auger is in the stirring state, the driving motor rotates in the reverse direction. The two acting parts respectively abut against the bottoms of the first spiral groove and the second spiral groove. The one-way tooth acts on the inclined part of the one-way body and drives the one-way body to move towards the direction of the first elastic member. The support column rotates synchronously with the stirring rod.

[0021] When the stirring and scraping auger is in the scraping state, the driving motor rotates in the forward direction. The two acting parts are both located in the annular groove in a movable manner. The one-way body abuts against the adjacent one-way tooth, and the support column is in a stationary state.

[0022] The present invention is further configured such that a plurality of reinforcing frames are provided on the inner wall of the outer guiding part. A reinforcing cylinder is vertically arranged between the tops of all the reinforcing frames. A reinforcing rod is vertically and rotatably arranged on the inner wall of the reinforcing cylinder. A second synchronization rod is vertically arranged at the top of the reinforcing rod. The cross-section of the second synchronization rod is rectangular. A second synchronization groove matching with the second synchronization rod is vertically formed at the bottom of the stirring rod.

The second scraping member is lower than the stirring and scraping auger. The outer side of the second scraping member fits against the inner wall of the accommodating part or has a set gap with the inner wall of the accommodating part. The second scraping member is used to drive the material on the accommodating part downward to the outer guiding part. When the stirring and scraping auger is in the scraping state, the top of the second scraping member is at the same height as the bottom of the stirring and scraping auger or higher than the bottom of the stirring and scraping auger.

[0026] The present invention is further configured such that the longitudinal cross-sections of the first scraping member and the second scraping member are both inclined. When the stirring and scraping auger is in the stirring state, both the first scraping member and the second scraping member drive the material upward.

[0027] Compared with the prior art, the present invention provides a novel concentration device. When concentrating the material in the kettle body, a heat medium is injected into the heating coil to raise the temperature of the liquid in the kettle body. At the same time, an air extraction pump is externally connected to the air extraction pipe to extract the gas in the kettle body outward, and at the same time, a certain degree of vacuum is created in the kettle body to accelerate the concentration process. During the concentration process, the sealing cover is threadedly connected to the feed pipe to prevent external air from entering the kettle body. After the concentration is completed, the control valve is opened to discharge the thick liquid or paste in the kettle body downward. For the material adhering to the inner wall of the kettle body, at this time, the lifting mechanism raises the height of the stirring rod, and at the same time, the driving mechanism drives the stirring rod to rotate, and the stirring and scraping auger scrapes the inner wall of the accommodating part, which can scrape, concentrate and drive downward the material adhering to the inner wall of the accommodating part, so that the material on the inner wall of the accommodating part can flow better to the bottom of the kettle body, facilitating downward discharge. During the stirring process, the stirring and scraping auger rotates, stirring and lifting the material upward, enabling the material concentration to be carried out efficiently.

[0028] Among them, the scenarios where this application is used are mainly materials (thick liquids or pastes) that are prone to adhering to the inner wall of the kettle body. At the same time, these materials need to be recycled, and it is difficult to clean them with solvents. Although the structure of this application cannot clean and scrape the entire inner wall of the kettle body, it can, to a large extent, concentrate and drive downward the material adhering to the inner wall of the kettle body, playing a great auxiliary role in cleaning the inner wall of the kettle body. During the stirring process, the stirring and scraping auger is in a separated state from the inner wall of the kettle body, which can not only prevent the wear of the stirring and scraping auger and the kettle body, but also prevent the debris of the stirring and scraping auger and the inner wall of the kettle body from entering the material, ensuring the concentration effect.

[0059] A second through hole 21 communicating with the first through hole 13 is vertically penetrated through the support column 16, the bottom of the output shaft 11 and the top of the stirring rod 7 are both attached to the inner wall of the second through hole 21, a circular ring-shaped annular groove 22 and a first spiral groove 23 and a second spiral groove 24 communicating with the bottom of the annular groove 22 are horizontally opened on the inner wall of the second through hole 21, the pitches of the first spiral groove 23 and the second spiral groove 24 are equal and the rotation directions are the same, the connection part of the first spiral groove 23 and the annular groove 22 is at one end of the annular groove 22, and the connection part of the second spiral groove 24 and the annular groove 22 is at the other end of the annular groove 22;

[0060] A first synchronizing rod 25, the first synchronizing rod 25 is vertically connected to the bottom of the output shaft 11, and the cross section of the first synchronizing rod 25 is rectangular, a first synchronizing groove 26 matching with the first synchronizing rod 25 is opened at the top of the stirring rod 7, and two acting parts 27 are disposed at the same height on the outer wall of the stirring rod 7, and the two acting parts 27 are located on both sides of the stirring rod 7;

[0061] When the stirring and scraping auger 9 is in the stirring state, the driving motor 10 rotates reversely, the two acting parts 27 respectively abut against the bottoms of the first spiral groove 23 and the second spiral groove 24, the one-way tooth 15 acts on the inclined part of the one-way body 19, and drives the one-way body 19 to move towards the direction of the first elastic member 20, and the support column 16 rotates synchronously with the stirring rod 7;

[0062] When the stirring and scraping auger 9 is in the scraping state, the driving motor 10 rotates forward, the two acting parts 27 are both movably located in the annular groove 22, the one-way body 19 abuts against the adjacent one-way tooth 15, and the support column 16 is in a stationary state.

[0063] A plurality of reinforcing frames 28 are arranged on the inner wall of the outer guiding part 1b. A reinforcing cylinder 29 is vertically arranged between the tops of all the reinforcing frames 28. A reinforcing rod 30 is vertically and rotatably arranged on the inner wall of the reinforcing cylinder 29. A second synchronous rod 31 is vertically arranged at the top of the reinforcing rod 30. The cross section of the second synchronous rod 31 is rectangular. A second synchronous groove 32 matching with the second synchronous rod 31 is vertically formed at the bottom of the stirring rod 7. The outer wall of the second synchronous rod 31 fits against the inner wall of the second synchronous groove 32.

[0064] A second elastic member 33 that is continuously in an extended state is arranged between the top of the second synchronous rod 31 and the top of the second synchronous groove 32.

[0065] A novel concentration device provided by the present invention, when concentrating the materials in the kettle body 1, a heat medium is injected into the heating coil 2 to increase the temperature of the liquid in the kettle body 1. At the same time, an air extraction pipe 3 is externally connected with an air extraction pump to extract the gas in the kettle body 1 outwards, and at the same time, a certain degree of vacuum is created in the kettle body 1 to accelerate the concentration process; during the concentration process, the sealing cover 6 is threadedly connected to the feed pipe 4 to prevent external air from entering the kettle body 1. After the concentration is completed, the control valve is opened to discharge the thick liquid or paste in the kettle body 1 downwards. For the materials adhered to the inner wall of the kettle body 1, at this time, the lifting mechanism raises the height of the stirring rod 7, and at the same time, the driving mechanism drives the stirring rod 7 to rotate, and makes the stirring and scraping auger 9 scrape the inner wall of the accommodating part 1a, so as to scrape, concentrate and drive down the materials adhered to the inner wall of the accommodating part 1a, so that the materials on the inner wall of the accommodating part 1a can flow better to the bottom of the kettle body 1 for convenient downward discharge. During the stirring process, the stirring and scraping auger 9 rotates to stir and lift the materials upwards, so that the material concentration can be carried out efficiently.

[0066] The scenarios in which this application is used mainly involve materials (thick liquids or pastes) that are prone to adhering to the inner wall of the kettle body 1. At the same time, these materials need to be recycled, and it is difficult to rinse them with solvents. Although the structure of this application cannot clean and scrape the entire inner wall of the kettle body 1, it can play a role in concentrating and driving downward the materials adhering to the inner wall of the kettle body 1 to a large extent, which plays a great auxiliary role in cleaning the inner wall of the kettle body 1. During the stirring process, the stirring and scraping auger 9 is in a separated state from the inner wall of the kettle body 1, which can not only prevent the loss of the stirring and scraping auger 9 and the kettle body 1, but also prevent the debris of the stirring and scraping auger 9 and the inner wall of the kettle body 1 from entering the materials, ensuring the concentration effect.

[0067] When concentrating, the driving motor 10 rotates in the reverse direction. At this time, the two acting parts 27 are respectively located at the bottoms of the first spiral groove 23 and the second spiral groove 24, and the stirring and scraping auger 9 is also at the lowest height. At this time, the output shaft 11, the first synchronizing rod 25, the stirring rod 7, the support column 16, and the one-way disc 17 all rotate synchronously. At the same time, the one-way body 19 repeatedly expands and contracts under the action of the one-way teeth 15 and the first elastic member 20, so that the one-way disc 17 can rotate.

[0068] When scraping the material, the driving motor 10 rotates forward. At this time, since the one-way teeth 15 limit the one-way body 19, the support column 16 and the one-way disc 17 cannot rotate. Therefore, the acting parts 27 move upward under the action of the first spiral groove 23 and the second spiral groove 24 until both acting parts 27 enter the annular groove 22. Since the annular groove 22 is horizontally annular, at this time, the acting parts 27 and the stirring rod 7 no longer rise, but can only rotate. At the same time, at this time, the stirring and scraping auger 9 fits on the inner wall of the accommodating part 1a, so it can scrape the inner wall of the accommodating part 1a. At this time, the moving directions of the two acting parts 27 are opposite to the spiral directions of the first spiral groove 23 and the second spiral groove 24, so the heights of the acting parts 27 and the stirring rod 7 can be maintained.

[0069] During the stirring and scraping process, the bottom of the stirring rod 7 drives the second synchronizing rod 31 and the reinforcing rod 30 to rotate through the second synchronizing groove 32. At this time, the reinforcing rod 30 and the second synchronizing rod 31 support the bottom of the stirring rod 7, improving the angular stability of the stirring rod 7 and preventing it from shaking; but at the same time, it does not affect the lifting of the stirring rod 7. Moreover, since the second elastic member 33 is always in an extended state, when the stirring and scraping auger 9 returns to the stirring state, the second elastic member 33 can apply a downward pulling force to the stirring rod 7 and make the two acting parts 27 more smoothly enter the top openings of the first spiral groove 23 and the second spiral groove 24, accelerating the return of the stirring and scraping auger 9.

[0070] Embodiment 2

[0071] It is different from the first embodiment in that, as Figure 13 and Figure 14 shown, an auxiliary rod 34 is horizontally arranged on the side wall of the consolidation rod 30. An arc-shaped first scraping member 35 is arranged at the free end of the auxiliary rod 34. The bottom of the first scraping member 35 fits against the inner wall of the outer guide portion 1b or has a set gap with the inner wall of the outer guide portion 1b. When the stirring and scraping auger 9 is in the scraping state, the first scraping member 35 is used to drive the material on the outer guide portion 1b to the top of the discharge pipe 5.

[0072] A second scraping member 36 is arranged at the top of the first scraping member 35. The second scraping member 36 is lower than the stirring and scraping auger 9. The outer side of the second scraping member 36 fits against the inner wall of the accommodating portion 1a or has a set gap with the inner wall of the accommodating portion 1a. The second scraping member 36 is used to drive the material on the accommodating portion 1a downward to the outer guide portion 1b. When the stirring and scraping auger 9 is in the scraping state, the top of the second scraping member 36 is at the same height as the bottom of the stirring and scraping auger 9 or higher than the bottom of the stirring and scraping auger 9.

[0073] The longitudinal sections of both the first scraping member 35 and the second scraping member 36 are inclined. When the stirring and scraping auger 9 is in the stirring state, both the first scraping member 35 and the second scraping member 36 drive the material upward.

[0074] In this embodiment, both the first scraping member 35 and the second scraping member 36 can either fit against the inner wall of the kettle body 1 or have a very small gap. If in the fitting state, when cleaning the inner wall of the kettle body 1, the first scraping member 35 and the second scraping member 36 can respectively scrape the inner wall of the outer guide portion 1b and the inner wall of the accommodating portion 1a. At the same time, the second scraping member 36 can drive the material downward, and the first scraping member 35 can drive the material towards the discharge pipe 5, all of which can accelerate the outward discharge of the material. If there is a gap between both of them and the inner wall of the kettle body 1, at this time, it can also scrape the thicker material, reduce the residual amount of the material, and at the same time reduce wear.

[0075] Moreover, both the first scraping member 35 and the second scraping member 36 have the function of driving the material to move upward during the stirring and concentration process, so as to prevent the formation of a heat insulation layer by the paste or thick material on the inner wall and bottom of the kettle body 1. That is, at this time, the material with a greater density at the bottom is driven upward, so that after this part of the thick material that has absorbed more heat can move upward, it transfers the temperature to the material in the middle of the kettle body 1, thereby slowing down the temperature rise of the middle material and accelerating the concentration. At the same time, since the thick material moves out from the inner wall of the kettle body 1, the thinner material can flow to the inner wall of the kettle body 1, so as to better heat up and vaporize, and also accelerate the concentration process.

[0076] It should also be added that all "settings" and similar descriptive words in this application (especially in the specification) express that there is a connection relationship between two structures, but there is no excessive limitation on the specific means of connection between the two, and usually it is a conventional connection means, that is, it should be understood that this means is the prior art and does not need to be elaborated too much. For example, "n is provided on m" only expresses that there is an n structure on the m structure, and whether the two are connected by welding, riveting, adhesive connection or integrally formed is within the protection scope of this application; another example is "y is rotatably provided on x", which only expresses that y and x can rotate relative to each other, and as for whether the two are rotatably connected by a bearing, or y directly passes through x and is rotatably connected to x, or other achievable ways, they are all within the protection scope of this application.

[0077] The above description is only a description of the preferred embodiments of the present invention, and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the field of the present invention based on the above disclosure are within the protection scope of the claims.
