When the material is put in, the above scheme can play a heat preservation effect because the top surface is sealed, and at the same time, because the discharge hole is located on the rotating shaft, located in the middle position of the reaction tank, the material can be spread very evenly, so that the material can be quickly stirred evenly. However, the above scheme still has the following shortcomings when it is actually used: The impurity removal and purification device for sucralose mother liquor proposed in the above scheme does not have the function of automatically adding impurity removal agents. The addition of impurity removal agents needs to be done manually, and manual addition may cause fluctuations and inconsistencies in the amount of agent added, which may affect the effect of impurity removal and the quality stability of the final product.

[0015] An operating method of a sucralose mother liquor impurity removal and purification device comprises the following steps: S1. Adding sucralose mother liquid: The staff puts the sucralose mother liquid into the vertical cylinder; S2. Start the stirring device: Start the motor to drive the stirring shaft to rotate, and the stirring rod on the stirring shaft starts to evenly stir the sucralose mother solution; S3, reciprocating motion of the transmission rod: The rotation of the stirring shaft drives the transmission rod through the transmission member, so that the reciprocating screw rod 2 reciprocates under the action of the limiting rod 2; S4, up and down movement of the slide 2: the movement of the reciprocating screw rod 2 drives the slide 2 to reciprocate on the upper part of the third mounting frame; S5. Effect of magnetic attraction: During the movement of the second slide, according to the positions of the first and second magnetic blocks, the magnetic slide and the magnetic slider are moved under the influence of the magnetic attraction, so that the magnetic slider is located in a parallel position to the liquid surface of the sucralose mother solution; S6. Control of the spray holes: According to the position of the magnetic slider, the flow direction of the impurity removal agent through the spray holes is controlled to ensure that only the spray holes located below the magnetic slider can release the impurity removal agent, thereby ensuring uniform distribution of the agent in the mother liquor; S7, Operation of the sealing cylinder: The up and down movement of the slide seat 2 also drives the sliding plug to move up and down inside the sealing cylinder, and two one-way valves are used to control the flow direction of the liquid to achieve automatic addition and mixing of the impurity removal agent; S8. Functions of scraper and sieve plate: When the liquid in the cylinder needs to be separated, the servo motor on the frame is started to rotate the cylinder, and the liquid passes through the mesh of the sieve plate to separate the sediment; S9. Maintenance and cleaning: After completing the reaction or operation, clean and maintain the device as needed to ensure the effectiveness and safety of the next use.

[0016] The present invention has the following beneficial effects: 1. When the sliding plug moves upward, it can draw the impurity removal agent in the storage tank into the sealing cylinder, and when it moves downward, it can press the agent into the inside of the stirring shaft and evenly distribute it through the spray holes. This mechanical device realizes the automatic addition of impurity removal agents. Compared with manual addition, this automated design reduces manual intervention and operation time, reduces labor costs, and improves stability and consistency throughout the production process, reducing possible human errors; 2. The uniform distribution of the spray holes ensures that the impurity removal agent can be evenly distributed throughout the cylinder and fully mixed with the sucralose mother liquor, which can avoid the situation where the local agent concentration is too high or too low, and ensure the uniformity and stability of the impurity removal process. Due to the uniform mixing of the impurity removal agent and the mother liquor, the agent distribution around each spray hole is more uniform, which effectively increases the contact area and reaction efficiency between the impurity removal agent and the target substance, thereby improving the impurity removal effect; 3. The up and down movement of the slide seat 2 is driven by the motor in the stirring structure, and no additional power source is required. The absence of an additional power source means a simpler design and a more convenient installation process, which reduces the complexity of the mechanical system and the coupling between components, simplifies the layout and installation steps of the production line, and achieves a linkage effect; 4. The staff can accurately control the up and down movement of the slide seat 1 by adjusting the knob on the reciprocating screw 1, thereby adjusting the position of the magnetic block 1, so that the stop position of the fixed block can be accurately controlled, and then the movement stroke of the slide plug and the amount of impurity removal agent added can be controlled. This flexibility allows the operator to make precise adjustments according to the specific amount and needs of the sucralose mother liquor. Since the movement of the slide seat and the position of the fixed block can be accurately controlled, the amount of impurity removal agent added can be accurately controlled, which is crucial for quality control in the production process and can ensure the quality and impurity removal effect of each batch of products; 5. The floating structure controls the position of the magnetic slider by floating the float on the liquid surface, ensuring that the magnetic slider is flush with the liquid surface. This design allows the impurity removal agent to flow out only through the spray hole below the magnetic slider, while the spray hole above is blocked, thereby ensuring that the agent is evenly distributed below the liquid surface, avoiding premature mixing or uneven concentration of the agent. Due to the uniform distribution and precise control of the agent, there will be no waste or unnecessary agent addition in the production process, reducing production costs and resource waste, while also improving production efficiency; 5. Through the 180° rotation of the cylinder and the design of the guide cover, the liquid and the sediment can be effectively separated during the rotation process. The liquid flows out through the mesh on the sieve plate, while the sediment remains on the sieve plate and settles. The gravity and centrifugal force are used to achieve a fast and effective separation process. The effective liquid and sediment separation process ensures the smooth progress of the subsequent processing stage, reduces the impact of sediment on equipment and processes, and thus improves production efficiency and product quality stability; 6. The sediment deposited on the sieve plate can be driven by the servo motor on the frame to rotate the cylinder, and then combined with the rotation of the scraper, the sediment can be scraped flat and removed in a centralized manner. This can avoid the problem of sediment blocking the sieve mesh, ensure that the liquid flows smoothly through the sieve plate and keeps the sieve plate clean. BRIEF DESCRIPTION OF THE DRAWINGS

Specifically, the staff rotates the knob at the upper end of the reciprocating screw 93 to rotate the reciprocating screw 93. When the reciprocating screw 93 rotates, under the limiting action of the limiting rod 92, the reciprocating screw 93 can drive the slide 94 to move up and down, and the magnetic block 95 will also move up and down accordingly. This design can control the stop position of the fixed block 81, thereby controlling the moving stroke of the slide plug 74. Therefore, the staff can flexibly control the amount of impurity-removing agent added according to the amount of sucralose mother liquor. The impurity removal and purification device also includes a driving structure, which is arranged on the outer circumference of the cylinder 2, and the driving structure includes: a third mounting frame 101, fixed on the outer circumference of the cylinder 2; a reciprocating screw rod 102, rotatably mounted on the third mounting frame 101; a limiting rod 103, fixed on the third mounting frame 101; a slide seat 104, threadedly sleeved on the reciprocating screw rod 102, and the slide seat 104 is slidably sleeved on the limiting rod 103; a second slideway 105, which is opened on the slide The second slide 106 is slidably disposed in the second slideway 105, and the second slide 106 is made of a magnetic material; a second opening 107 is provided on the top surface of the second slide 104 and is connected to the second slideway 105; a second slider 108 is fixed on the top surface of the second slide 106 and slidably disposed in the second opening 107; a second magnetic block 109 is fixed on the third mounting frame 101; a transmission rod 1010 is fixed on the reciprocating screw rod 10 2; transmission member 1011, the transmission rod 1010 and the stirring shaft 53 are connected by the transmission member 1011, and the sliding seat 104 can drive the sliding plug 74 to move up and down inside the sealing cylinder 73 during the up and down movement. Since the limiting directions of the two one-way valves 78 are opposite, specifically, one of the one-way valves 78 limits the liquid to only enter the sealing cylinder 73, and the other one-way valve 78 limits the liquid to only flow out of the sealing cylinder 73. Therefore, when the sliding plug 74 moves up, the sliding plug 74 can The impurity-removing agent in the storage tank 4 is drawn into the sealing cylinder 73. When the sliding plug 74 moves downward, the sliding plug 74 can press the drawn impurity-removing agent into the interior of the stirring shaft 53, so that the impurity-removing agent flows out through the plurality of spray holes 55. This design can realize the automatic addition of the impurity-removing agent. In addition, the plurality of spray holes 55 are evenly distributed on the stirring shaft 53, so that the impurity-removing agent can be evenly distributed inside the cylinder 2, ensuring that the impurity-removing agent is fully and comprehensively mixed with the sucralose mother liquor, and ensuring the impurity-removing effect of the impurity-removing agent on the sucralose mother liquor; The stirring shaft 53 is provided with a floating structure, which includes: a magnetic slide 61, which is slidably arranged on the stirring shaft 53; a guide rod 62, which is fixed on the stirring shaft 53, and the magnetic slide 61 is slidably sleeved on the guide rod 62; a float 63, which is fixed on the side of the magnetic slide 61; a magnetic slider 64, which is slidably arranged inside the stirring shaft 53, and the outer peripheral surface of the magnetic slider 64 and the inner surface of the stirring shaft 53 are mutually attached. When the staff adds sucralose mother liquor into the cylinder 2, as the liquid level of the sucralose mother liquor increases, the float The capsule 63 can float on the liquid surface of the sucralose mother liquid. When the floating capsule 63 moves, it can drive the magnetic slide 61 to move. When the magnetic slide 61 moves, it can drive the magnetic slider 64 to move under the action of magnetic attraction, so that the magnetic slider 64 is located at a position flush with the liquid surface of the sucralose mother liquid. In this case, the impurity-removing agent can only flow out through the plurality of spray holes 55 located below the magnetic slider 64, but cannot flow out through the plurality of spray holes 55 located above the magnetic slider 64. This design can further ensure the uniformity of the distribution of the impurity-removing agent in the sucralose mother liquid. The cylinder 2 is provided with a de-impurity structure inside, and the de-impurity structure includes: a sieve plate 111, which is placed inside the cylinder 2; a plurality of sieve holes 112, which are evenly arranged on the sieve plate 111; a guide cover 113, which is fixed at the top of the cylinder 2, and the guide cover 113 is arranged opposite to the sieve plate 111; a mounting plate 114, which is fixed on the guide cover 113; a sleeve 115, which is rotatably mounted on the mounting plate 114; a plurality of axial flow blades 116, which are all fixed on the sleeve 115; a scraper 117, which is fixed at one end of the sleeve 115, and the scraper 117 is in contact with the surface of the sieve plate 111.

In addition, in the process of the liquid flowing through the guide cover 113, the sleeve 115 can be driven to rotate by the several axial flow blades 116, and the sleeve 115 can drive the scraper 17 to rotate when it rotates. The scraper 117 can scrape the sediment deposited on the sieve plate 111 during the rotation process to avoid the sediment blocking the sieve holes 112, and ensure that the liquid can smoothly pass through the several sieve holes 112.

[0021] The specific working principle of the present invention is as follows: When the impurity removal and purification device for sucralose mother liquor proposed by the present invention is in use, in the initial state, the cylinder 2 is in a vertical state. When the sucralose mother liquor is impurity removed and purified, the staff puts the sucralose mother liquor into the cylinder 2, and then starts the motor 52. When the motor 52 is running, it can drive the stirring shaft 53 to rotate. During the rotation of the stirring shaft 53, the plurality of stirring rods 54 thereon can stir the sucralose mother liquor in the cylinder 2. In addition, when the stirring shaft 53 rotates, it can also drive the transmission rod 1010 to rotate through the transmission member 1011, so that the transmission rod 1010 drives the reciprocating screw rod 102 to rotate. Under the limiting action of the limiting rod 103, the reciprocating screw rod 102 can drive the slide seat 104 from the first The lower end of the third mounting frame 101 moves toward the upper end of the third mounting frame 101. In the initial state, one end of the first slide 83 close to the second slide seat 104 extends to the outside of the first slideway 82, and one end of the second slide 106 close to the fixed block 81 extends to the outside of the second slideway 105, and one end of the second slide 106 close to the fixed block 81 is located between the first slide 83 and the protrusion 86. In this case, when the second slide seat 104 drives the second slide 106 to move upward, the second slide 106 can push the first slide 83, so that the first slide 83 drives the fixed block 81 to move upward. When the fixed block 81 moves upward, it can drive the sliding plug 74 to move upward through the connecting rod 75. In the process of the fixed block 81 moving upward, when the first slide 83 moves to the position facing the magnetic block When the first slide 83 is in the position of the first slide 83, the magnetic block 105 will exert a magnetic attraction on the first slide 83, so that the first slide 83 is adsorbed on the magnetic block 105, and then the first slide 83 moves. When the first slide 83 moves, the end of the first slide 83 close to the second slide 104 will be retracted into the first slideway 82 and separated from the second slide 106. In this case, the second slide 106 will not drive the fixed block 81 to continue to move up through the first slide 83. When the second slide 104 moves to the top position of the reciprocating screw rod 102, the second slide 104 will move downward. During the downward movement of the second slide 104, the second slide 106 will contact with the protrusion 86 and push the fixed block 81 downward through the protrusion 86. When the fixed block 81 moves to the position close to the first slide 83, the second slide 106 will not drive the fixed block 81 to continue to move up. When the sealing cylinder 73 is in the position, the second slide plate 106 just moves to the position facing the second magnetic block 109. At this time, the second magnetic block 109 will exert a magnetic attraction on the second slide plate 106, so that the second slide plate 106 is adsorbed on the second magnetic block 109, and then the second slide plate 106 moves. When the second slide plate 106 moves, the end of the second slide plate 106 close to the fixed block 81 will retract into the second slideway 105 and separate from the protrusion 86. In this case, the protrusion 86 will not hinder the movement of the second slide seat 104, avoiding the phenomenon of motion interference between the protrusion 86 and the second slide seat 104. When the second slide plate 106 is adsorbed on the second magnetic block 109, the position of the second slide plate 106 in the second slideway 105 will be fixed. In this case,The second slide 104 and the second slide plate 106 will no longer contact the protrusion 86 during the reciprocating movement, thereby avoiding the motion interference between the protrusion 86 and the second slide 104; Based on the above process, the sliding seat 104 can drive the sliding plug 74 to move up and down inside the sealing cylinder 73 during the process of moving up and down. Since the flow limiting directions of the two one-way valves 78 are opposite, specifically, one of the one-way valves 78 restricts the liquid to only enter the sealing cylinder 73, and the other one-way valve 78 restricts the liquid to only flow out of the sealing cylinder 73. Therefore, when the sliding plug 74 moves up, the sliding plug 74 can draw the impurity-removing agent in the storage tank 4 into the sealing cylinder 73. When the sliding plug 74 moves down, the sliding plug 74 can press the extracted impurity-removing agent into the inside of the stirring shaft 53, so that the impurity-removing agent flows out through the plurality of spray holes 55. This design can realize the automatic addition of the impurity-removing agent. In addition, the plurality of spray holes 55 are evenly distributed on the stirring shaft 53, which enables the impurity-removing agent to be evenly distributed inside the cylinder 2, ensuring that the impurity-removing agent is fully and comprehensively mixed with the sucralose mother liquor, and ensuring the impurity-removing effect of the impurity-removing agent on the sucralose mother liquor. The second mounting frame 91 is provided with a slide 94 that can move up and down, and a magnetic block 95 is fixed on the slide 94. The staff can control the amount of impurity removal agent added by adjusting the slide 94. Specifically, the staff turns the knob on the upper end of the reciprocating screw 93 to rotate the reciprocating screw 93. When the reciprocating screw 93 rotates, under the limiting action of the limiting rod 92, the reciprocating screw 93 can drive the slide 94 to move up and down, and the magnetic block 95 will also move up and down accordingly. This design can control the stop position of the fixed block 81, thereby controlling the moving stroke of the sliding plug 74. Therefore, the staff can flexibly control the amount of impurity removal agent added according to the amount of sucralose mother liquor. A floating structure is provided on the stirring shaft 53. When the staff adds sucralose mother liquid into the cylinder 2, as the liquid level of the sucralose mother liquid increases, the float 63 can float on the liquid surface of the sucralose mother liquid. When the float 63 moves, it can drive the magnetic slide 61 to move. When the magnetic slide 61 moves, it can drive the magnetic slider 64 to move under the action of magnetic attraction, so that the magnetic slider 64 is located at a position flush with the liquid surface of the sucralose mother liquid. In this case, the impurity-removing agent can only flow out through the plurality of spray holes 55 located below the magnetic slider 64, but cannot flow out through the plurality of spray holes 55 located above the magnetic slider 64. This design can further ensure the uniformity of the distribution of the impurity-removing agent in the sucralose mother liquid. A de-impurity structure is also provided in the cylinder 2. After the reaction is completed, the staff can start the servo motor on the frame 1 and use the servo motor to drive the cylinder 2 to rotate, so that the cylinder 2 rotates 180°. When the cylinder 2 rotates 180°, the liquid and sediment in the cylinder 2 will flow through the guide cover 113 and the sieve plate 111, and the liquid will pass through the several sieve holes 112 on the sieve plate 111, and the sediment will be deposited on the sieve plate 111. The several sieve plates 112 can separate the liquid and the sediment, so that the staff can remove the sediment mixed in the liquid. In addition, when the liquid flows through the guide cover 113, the sleeve 115 can be driven to rotate by the several axial flow blades 116. When the sleeve 115 rotates, it can also drive the scraper 17 to rotate. During the rotation process, the scraper 117 can scrape the sediment deposited on the sieve plate 111 flat, so as to avoid the sediment blocking the sieve holes 112, and ensure that the liquid can smoothly pass through the several sieve holes 112.
