Description

Technical Field

[0001] The present invention relates to the technical field of purification of sucralose mother liquor, and particularly relates to an impurity removal and purification device for sucralose mother liquor and an operation method thereof. Background Art

[0002] Sucralose mother liquor may contain some impurities during the production process and needs to be subjected to impurity removal treatment. These impurities may include unreacted starting materials, by-products, solvent residues, etc.

[0003] After retrieval, a Chinese patent with the publication number CN219051308U discloses a purification device for sucralose aqueous solution, including a reaction tank with a heating function. The top surface of the reaction tank is sealed and a discharge valve is provided at the lower part. A rotating shaft is vertically arranged in the reaction tank, and a stirring rod is fixedly arranged on the rotating shaft. The upper end of the rotating shaft passes through the reaction tank and is rotatably connected to the top surface of the reaction tank through a bearing. The rotating shaft is driven by a driving device to rotate along its axial line; a feed channel is opened downward on the top surface of the rotating shaft, and a discharge hole communicating with the feed channel is opened on the side surface of the rotating shaft. The feed channel is closed by a valve arranged on the rotating shaft. In the above solution, when feeding materials, due to the sealed top surface, it can play a heat preservation effect. At the same time, since the discharge hole is located on the rotating shaft and at the middle position of the reaction tank, the materials can be evenly scattered, so that the materials can be quickly stirred evenly. However, when the above solution is actually used, there are still the following deficiencies:

[0004] The impurity removal and purification device for sucralose mother liquor proposed in the above solution does not have the function of automatically adding impurity removal agents. The addition of impurity removal agents needs to be manually completed. Manual addition may lead to fluctuations and inconsistencies in the dosage of the agents, which may affect the impurity removal effect and the quality stability of the final product. In addition, manual addition requires additional manpower and time investment, especially in large-scale production, which may increase the production cycle and cost.

[0005] Therefore, it is necessary to design an impurity removal and purification device for sucralose mother liquor and an operation method thereof to solve the above problems. Summary of the Invention

[0072] An operation method of an impurity removal and purification device for sucralose mother liquor includes the following steps:

[0073] S1. Input the sucralose mother liquor: The staff inputs the sucralose mother liquor into the vertical cylinder body.

[0074] S2. Start the stirring device: Start the motor to drive the stirring shaft to rotate, and the stirring rods on the stirring shaft start to uniformly stir the sucralose mother liquor.

[0075] S3. Reciprocating movement of the transmission rod: The rotation of the stirring shaft drives the transmission rod through the transmission part, so that the reciprocating screw rod II makes a reciprocating movement under the action of the limiting rod II.

[0076] S4. Up and down movement of the sliding seat II: The movement of the reciprocating screw rod II drives the sliding seat II to reciprocate on the upper part of the third mounting frame.

[0077] S5. Action of magnetic attraction: During the movement of the sliding seat II, according to the positions of the magnetic block I and the magnetic block II, the magnetic sliding seat and the magnetic sliding block move under the influence of magnetic attraction, so that the magnetic sliding block is located at the parallel position of the liquid level of the sucralose mother liquor.

[0078] S6. Control of the spray holes: According to the position of the magnetic sliding block, control the flow direction of the impurity removal agent through the spray holes to ensure that only the spray holes below the magnetic sliding block can release the impurity removal agent, so as to ensure the uniform distribution of the agent in the mother liquor.

[0079] S7. Operation of the sealing cylinder: The up and down movement of the sliding seat II also drives the sliding plug to move up and down inside the sealing cylinder, and uses two one-way valves to control the liquid flow direction to realize the automatic addition and mixing of the impurity removal agent.

[0080] S8. Action of the scraper and the sieve plate: When it is necessary to separate the liquid in the cylinder body, start the servo motor on the frame to rotate the cylinder body by 180°, and the liquid separates the precipitate through the sieve holes of the sieve plate.

[0081] S9. Maintenance and cleaning: After the reaction or operation is completed, clean and maintain the device as needed to ensure the effect and safety of the next use.

[0082] The present invention has the following beneficial effects:

[0083] 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;

[0084] 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;

[0085] 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;

[0086] 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;

[0087] 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;

[0088] 5. Through the 180° rotation of the cylinder body and the design of the deflector, the liquid and sediment can be effectively separated during the rotation process. The liquid flows out through the sieve holes on the sieve plate, while the sediment remains on the sieve plate and deposits. By utilizing the effects of gravity and centrifugal force, a rapid and effective separation process is achieved. The effective liquid-sediment separation process ensures the smooth progress of the subsequent treatment stage, reduces the impact of sediment on the equipment and process, and thus improves the production efficiency and the stability of product quality.

[0089] 6. The sediment deposited on the sieve plate can be removed by driving the rotation of the cylinder body by the servo motor on the frame and then combining with the rotation of the scraper to scrape the sediment flat and remove it centrally. This can avoid the problem of sediment clogging the sieve holes, ensure the smooth flow of the liquid through the sieve plate, and keep the sieve plate clean. BRIEF DESCRIPTION OF THE DRAWINGS

When the motor 52 operates, it can drive the stirring shaft 53 to rotate. During the rotation of the stirring shaft 53, a plurality of stirring rods 54 thereon can stir the sucralose mother liquor in the cylinder body 2;

[0107] The impurity removal and purification device further includes a suction structure, which is arranged on the outer peripheral surface of the cylinder body 2. The suction structure includes: a first mounting bracket 71, which is fixed on the outer peripheral surface of the cylinder body 2; two connecting rods 72, which are respectively fixed at the upper and lower ends of the first mounting bracket 71; a sealing cylinder 73, which is fixed at one end of the two connecting rods 72 away from the first mounting bracket 71; a sliding plug 74, which is hermetically slidably connected to the inner surface of the sealing cylinder 73; a connecting rod 75, one end of which is fixedly connected to the sliding plug 74, and the other end extends to the outside of the sealing cylinder 73; a spring 76, one end of which is connected to the inner surface of the sealing cylinder 73, and the other end is connected to the sliding plug 74; two mounting pipes 77, one end of each of which is communicated with the sealing cylinder 73. The other end of one of the mounting pipes 77 is communicated with the storage tank 4, and the other end of the other mounting pipe 77 is communicated with the inside of the stirring shaft 53 through a rotary joint; two one-way valves 78, which are respectively installed on the two mounting pipes 77;

[0108] The impurity removal and purification device further includes a control structure, which is arranged directly above the suction structure. The control structure includes: a fixed block 81, which is fixed at one end of the connecting rod 75 outside the sealing cylinder 73; a first slideway 82, which is opened on the side surface of the fixed block 81; a first slide plate 83, which is slidably arranged in the first slideway 82, and the first slide plate 83 is made of a magnetic material; a first opening 84, which is opened on the top surface of the fixed block 81 and is communicated with the first slideway 82; a first slider 85, which is fixed on the top surface of the first slide plate 83 and is slidably arranged in the first opening 84; a convex block 86, which is fixed on the side surface of the fixed block 81;

[0109] The impurity removal and purification device also includes an adjustment structure, which is arranged on the outer peripheral surface of the cylinder 2, and the adjustment structure includes: a second mounting frame 91, fixed to the side of the first mounting frame 71; a limit rod 92, fixed to the second mounting frame 91; a reciprocating screw rod 93, rotatably mounted on the second mounting frame 91; a slide 94, threadedly sleeved on the reciprocating screw rod 93, and the slide 94 is slidably sleeved on the limit rod 92; a magnetic block 95, fixed to the side of the slide 94, and the staff can adjust the slide by adjusting the slide The amount of impurity-removing agent added is controlled by a method of rotating the reciprocating screw 93. 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.

[0110] 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;

When the staff adds the sucralose mother liquor into the cylinder body 2, with the increase of the liquid level of the sucralose mother liquor, the floating bladder 63 can float on the liquid surface of the sucralose mother liquor. When the floating bladder 63 moves, it can drive the magnetic sliding seat 61 to move. When the magnetic sliding seat 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 liquor. In this case, the impurity removal agent can only flow out through a plurality of spray holes 55 located below the magnetic slider 64, and cannot flow out through a plurality of spray holes 55 located above the magnetic slider 64. This design can further ensure the uniformity of the distribution of the impurity removal agent in the sucralose mother liquor;

[0112] An impurity removal structure is provided inside the cylinder body 2. The impurity removal structure includes: a sieve plate 111, placed inside the cylinder body 2; a plurality of sieve holes 112, evenly opened on the sieve plate 111; a diversion hood 113, fixed at the top position of the cylinder body 2, and the diversion hood 113 is arranged opposite to the sieve plate 111; a mounting plate 114, fixed on the diversion hood 113; a sleeve 115, rotatably installed on the mounting plate 114; a plurality of axial flow blades 116, all fixed on the sleeve 115; a scraper 117, fixed at one end of the sleeve 115, and the scraper 117 is in close contact with the surface of the sieve plate 111. 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 body 2 to rotate, so that the cylinder body 2 rotates by 180°. When the cylinder body 2 rotates by 180°, the liquid and sediment in the cylinder body 2 will flow through the diversion hood 113 and the sieve plate 111. The liquid will pass through a plurality of sieve holes 112 on the sieve plate 111, while the sediment will be deposited on the sieve plate 111. The plurality of sieve plates 112 can separate the liquid and the sediment, facilitating the staff to remove the sediment doped in the liquid. In addition, during the process of the liquid flowing through the diversion hood 113, it can drive the sleeve 115 to rotate through a plurality of axial flow blades 116. When the sleeve 115 rotates, it can drive the scraper 17 to rotate. During the rotation of the scraper 117, it can scrape the sediment deposited on the sieve plate 111 flat, avoiding the phenomenon that the sediment blocks the sieve holes 112 and ensuring that the liquid can smoothly pass through a plurality of sieve holes 112.

[0113] The specific working principle of the present invention is as follows:

[0114] 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 body 2 is in a vertical state. When removing impurities and purifying the sucralose mother liquor, the staff puts the sucralose mother liquor into the interior of the cylinder body 2, and then starts the motor 52. When the motor 52 operates, it can drive the stirring shaft 53 to rotate. During the rotation of the stirring shaft 53, a plurality of stirring rods 54 thereon can stir the sucralose mother liquor in the cylinder body 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 lead screw two 102 to rotate. Under the limiting action of the limiting rod two 103, when the reciprocating lead screw two 102 rotates, it can drive the sliding seat two 104 to move from the lower end of the third mounting frame 101 towards the upper end of the third mounting frame 101. In the initial state, one end of the first sliding plate 83 close to the sliding seat two 104 extends outside the first slideway 82, and one end of the second sliding plate 106 close to the fixed block 81 extends outside the second slideway 105, and one end of the second sliding plate 106 close to the fixed block 81 is located between the first sliding plate 83 and the convex block 86. In this case, when the sliding seat two 104 drives the second sliding plate 106 to move upward, the second sliding plate 106 can push the first sliding plate 83, so that the first sliding plate 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. During the upward movement of the fixed block 81, when the first sliding plate 83 moves to a position directly opposite to the first magnetic block 95, the first magnetic block 95 will exert a magnetic attraction force on the first sliding plate 83, so that the first sliding plate 83 is adsorbed on the first magnetic block 95, and then the first sliding plate 83 moves. When the first sliding plate 83 moves, one end of the first sliding plate 83 close to the sliding seat two 104 will shrink into the first slideway 82 and be separated from the second sliding plate 106. In this case, the second sliding plate 106 will not drive the fixed block 81 to continue to move upward through the first sliding plate 83. When the sliding seat two 104 moves to the top position of the reciprocating lead screw two 102, the sliding seat two 104 will move downward. During the downward movement of the sliding seat two 104, the second sliding plate 106 will contact the convex block 86 and push the fixed block 81 to move downward through the convex block 86. When the fixed block 81 moves to a position close to the sealing cylinder 73, the second sliding plate 106 just moves to a position directly opposite to the second magnetic block 109. At this time, the second magnetic block 109 will exert a magnetic attraction force on the second sliding plate 106, so that the second sliding plate 106 is adsorbed on the second magnetic block 109, and then the second sliding plate 106 moves. When the second sliding plate 106 moves, one end of the second sliding plate 106 close to the fixed block 81 will shrink into the second slideway 105 and be separated from the convex block 86. In this case, the convex block 86 will not hinder the movement of the sliding seat two 104, avoiding the phenomenon of movement interference between the convex block 86 and the sliding seat two 104. When the second sliding plate 106 is adsorbed on the second magnetic block 109, the position of the second sliding plate 106 in the second slideway 105 will be fixed. In this case,During the reciprocating movement of the second sliding seat 104 and the second sliding plate 106, they will no longer contact the bump 86, avoiding the phenomenon of movement interference between the bump 86 and the second sliding seat 104;

[0115] Based on the above process, during the up and down movement of the second sliding seat 104, it can drive the sliding plug 74 to move up and down inside the sealing cylinder 73. Since the current 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 upward, the sliding plug 74 can suck the impurity removal agent in the storage tank 4 into the sealing cylinder 73. When the sliding plug 74 moves downward, the sliding plug 74 can press the sucked impurity removal agent into the inside of the stirring shaft 53, so that the impurity removal agent flows out through a plurality of spray holes 55. This design can realize the automatic addition of the impurity removal agent. In addition, the plurality of spray holes 55 are evenly distributed on the stirring shaft 53, which enables the impurity removal agent to be evenly distributed inside the cylinder body 2, ensuring that the impurity removal agent is fully and comprehensively mixed with the sucralose mother liquor, and ensuring the impurity removal effect of the impurity removal agent on the sucralose mother liquor;

[0116] A first sliding seat 94 that can move up and down is provided on the second mounting bracket 91. A first magnetic block 95 is fixed on the first sliding seat 94. The staff can control the addition amount of the impurity removal agent by adjusting the first sliding seat 94. Specifically, the staff rotates the knob at the upper end of the reciprocating lead screw 93 to make the reciprocating lead screw 93 rotate. When the reciprocating lead screw 93 rotates, under the limiting action of the first limiting rod 92, the reciprocating lead screw 93 can drive the first sliding seat 94 to move up and down, and the first magnetic block 95 will also move up and down accordingly. This design can control the staying 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 the added impurity removal agent according to the amount of the sucralose mother liquor;

[0117] A floating structure is provided on the stirring shaft 53. When the staff adds the sucralose mother liquor into the cylinder body 2, as the liquid level of the sucralose mother liquor increases, the floating bladder 63 can float on the liquid surface of the sucralose mother liquor. When the floating bladder 63 moves, it can drive the magnetic sliding seat 61 to move. When the magnetic sliding seat 61 moves, it can drive the magnetic sliding block 64 to move under the action of magnetic attraction, so that the magnetic sliding block 64 is located at a position flush with the liquid surface of the sucralose mother liquor. In this case, the impurity removal agent can only flow out through a plurality of spray holes 55 located below the magnetic sliding block 64, and cannot flow out through a plurality of spray holes 55 located above the magnetic sliding block 64. This design can further ensure the evenness of the distribution of the impurity removal agent in the sucralose mother liquor;

[0118] A impurity removal structure is also arranged inside the cylinder body 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 body 2 to rotate, so that the cylinder body 2 rotates by 180°. When the cylinder body 2 rotates by 180°, the liquid and sediment in the cylinder body 2 will flow through the flow guide cover 113 and the sieve plate 111. The liquid will pass through several sieve holes 112 on the sieve plate 111, while the sediment will be deposited on the sieve plate 111. The several sieve plates 112 can separate the liquid and the sediment, facilitating the staff to remove the sediment doped in the liquid. In addition, when the liquid flows through the flow guide cover 113, it can drive the sleeve 115 to rotate through several axial flow blades 116. When the sleeve 115 rotates, it can drive the scraper 17 to rotate. During the rotation process, the scraper 117 can scrape the sediment deposited on the sieve plate 111 flat, avoiding the phenomenon that the sediment blocks the sieve holes 112, and ensuring that the liquid can smoothly pass through several sieve holes 112.
