Description

Technical Field

[0001] The present invention relates to the technical field of food production, and specifically to a post-treatment device for sucralose chloride solution. Background Art

[0002] Sucralose generally refers to sucralose, which is a sweetener with a sweetness 400 - 800 times that of sucrose. It has very stable chemical and physical properties, is non-toxic and harmless, is extremely soluble in water, methanol and ethanol, and its aqueous solution is neutral. It is an ideal sweetener with no calories, high sweetness and high safety.

[0003] In the existing production of sucralose, raw materials are chlorinated through a kettle reactor to obtain sucralose - 6 - acetate (an important intermediate for obtaining sucralose). In this process, it is necessary to control the pH by adding a weak acidic solution or a weak alkaline solution, adsorb waste residues and precipitates in the solution by adding activated carbon, and obtain the activated carbon and waste residue precipitates by filtration for incineration or burial.

[0004] There are the following problems in the post - treatment process of the existing sucralose chloride solution:

[0005] During the filtration process, it is necessary to interrupt the preparation process to filter the solution, separate the activated carbon, waste residues and precipitates in the solution, and then continue the preparation of sucralose after filtration. This greatly affects the preparation efficiency of sucralose.

[0006] During the filtration process, due to long - term repeated filtration, the filtration device is prone to clogging, making the filtration unable to proceed smoothly. It is necessary to interrupt the preparation process to replace the filtration device, seriously affecting the preparation efficiency.

[0007] After filtration, there is a certain amount of fine activated carbon floating on the surface of the solution, affecting the purity of the prepared solution. The substances adsorbed by the activated carbon also affect the pH of the solution, and it is very troublesome to handle the floating activated carbon. Summary of the Invention

The temperature control clamping cover unit 9 outside the device main body 1 can control the temperature of the liquid inside the device main body 1.

[0033] Please refer to Figure 1 and Figure 3 , a power mechanism 201 is rotatably connected to the top end of the drive control unit 2. A support 202 is fixedly connected to the bottom end of the power mechanism 201. A stirring and transmission mechanism 203 is rotatably connected to the bottom end of the power mechanism 201. A stirring blade 204 is fixedly connected to the bottom end of the stirring and transmission mechanism 203. The filter screen cleaning unit 3 is rotationally engaged with the bottom of the stirring and transmission mechanism 203 near the bottom end.

[0034] In the present invention, the drive control unit 2 drives the stirring and transmission mechanism 203 to rotate through the driving of the power mechanism 201 at the top, further driving the stirring blades 204 to stir.

A cleaning brush belt 308 is sleeved on the outer side of the cleaning shaft 307.

[0036] In the present invention, the central gear 301 of the filter screen cleaning unit 3 drives the chain 302 to move, further driving the driven gear 304 on the fixed frame 303 to rotate. After the driven gear 304 rotates, it drives the cleaning shaft 307 at the bottom to rotate, further causing the cleaning brush belt 308 to move to achieve the cleaning effect. At the same time, the movement of the chain 302 causes the gear shaft 305 at the right end to rotate. The rotation of the gear on the upper part of the gear shaft 305 enables the filter screen cleaning unit 3 to rotate around the central gear 301, enabling the filter screen cleaning unit 3 to clean while rotating.

[0037] Please refer to Figure 3 , the activated carbon filtering unit includes a filter plate 401. The central position of the filter plate 401 is penetrated and rotatably connected by the drive control unit 2. The outer side wall of the filter plate 401 is fixedly connected to the inner wall of the device main body 1. An activated carbon filtering layer 402 is fixedly arranged at the bottom of the filter plate 401. A bottom water filtering plate 403 is fixedly connected to the bottom of the activated carbon filtering layer 402.

[0038] In the present invention, an activated carbon filtering layer 402 is sandwiched between the filter plate 401 and the water filtering plate.

The filter plate 401 and the activated carbon are mainly responsible for filtering impurities in water, and the filter plate 401 and the water filtering plate mainly fix the activated carbon filtering layer 402.

[0039] Please refer to Figure 4 , Figure 5 and Figure 6, the floating object suction unit 6 includes a liquid pump 601, the bottom end of the liquid pump 601 is fixedly connected to the top surface of a load-bearing plate 602, the bottom surface of the load-bearing plate 602 is fixedly connected to the top end of a surrounding plate 603, a liquid suction pipe 604 is arranged at the left end of the liquid pump 601, the bottom end of the liquid suction pipe 604 is fixedly connected to a suction circular pipe 605, the suction circular pipe 605 penetrates through a cover plate 606, a power cord 607 is fixedly connected to the rear end of the liquid pump 601, a stabilizer 608 is fixedly connected to the tail end of the power cord 607, and a buoyancy switch 609 is slidably connected inside the stabilizer 608 at the tail end of the power cord 607.

[0040] In the present invention, the floating object suction unit 6 uses the liquid pump 601 at the top to suck the floating objects inside the surrounding plate 603 through the liquid suction pipe 604 and the suction circular pipe 605, and the switch of the liquid pump 601 is controlled by the buoyancy transmission unit 7.

[0041] Please refer to Figure 5 and Figure 6 , the buoyancy transmission unit 7 includes four buoyancy control mechanisms 701. The four buoyancy control mechanisms 701 are evenly distributed at the bottom end of the buoyancy transmission unit 7 and are fixedly connected to the side surface of the bottom plate. The top end of the rear buoyancy control mechanism 701 among the four buoyancy control structures is fixedly connected to the buoyancy switch 609, and the bottom plate is hermetically connected to the inside of the bottom surrounding plate 603 of the buoyancy transmission unit 7.

[0042] In the present invention, during the process of the liquid level and the floating objects gradually rising, the buoyancy control mechanism 701 gradually rises under the action of buoyancy, further driving the buoyancy switch 609 at the top of the buoyancy control mechanism 701 to rise and connect to the power cord 607 of the floating suction unit, thereby turning on the power supply and causing the liquid pump 601 to start working. When the floating objects gradually decrease, the buoyancy control unit gradually descends, causing the buoyancy switch 609 to descend and disconnect from the power cord 607, and the liquid pump 601 will stop working.

[0043] Please refer to Figure 6, the buoyancy control mechanism 701 includes a floating block 7011. One end of each of two rotating rods 7012 is rotatably connected to the floating block 7011. The middle parts of the two rotating rods 7012 are rotatably connected to a fixed rod 7013. The fixed rod 7013 is fixedly connected to the outer side wall of the enclosing plate 603. The other ends of the two rotating rods 7012 are respectively slidably connected to sliding position plates 7014. Both of the two sliding position plates 7014 are fixedly connected to the two ends of one side surface of the bottom plate. A chute 7015 is provided inside each of the two sliding position plates 7014. A rubber connecting belt 7016 is slidably connected inside the two chutes 7015. A rotating shaft 7017 is provided at the top of each of the two sliding position plates 7014. One end of each of the two rubber connecting belts 7016 is fixedly connected to one end of the rotating rod 7012, and the other end is fixedly connected to a stepping motor 7018. The middle parts of the two rubber connecting belts 7016 are slidably connected to the rotating shafts 7017. The two stepping motors 7018 are respectively slidably connected to two guide rails 7019. The two guide rails 7019 penetrate through the stepping motors 7018 and their upper and lower ends are respectively fixedly connected to fixed blocks 7020. Both of the two fixed blocks 7020 are fixedly connected to the inner sides of the sliding position plates 7014. An opening and closing door plate 7021 is fixedly connected to the outer sides of the two stepping motors 7018. A floating object inlet 7022 is provided at the corresponding position of the outer side of the enclosing plate 603 and the opening and closing door plate 7021 to facilitate the entry of liquid and floating objects.

[0044] In the present invention, the buoyancy control mechanism 701 utilizes the buoyancy generated by the floating block 7011 to lift the rotating rod 7012 upward. By the downward sliding of the other end of the rotating rod 7012 in the chute 7015, the rubber connecting belt 7016 slides downward simultaneously, further driving the stepping motor 7018 at the other end of the rubber connecting belt 7016 to move upward, and then moving the opening and closing door plate 7021 upward to open the floating object inlet 7022.

[0045] Please refer to Figure 1 、 Figure 2 and Figure 3 , the temperature control cover unit 9 includes a covering outer layer 901. The covering outer layer 901 is fixedly covered on the outer wall of the device main body 1. A high-temperature port 902 is provided at the left top of the covering outer layer 901, and a low-temperature port 903 is provided at the right bottom of the covering outer layer 901.

[0046] In the present invention, the temperature control cover unit 9 is used to control the heating or cooling of the liquid inside the device main body 1. When heating is required, high-temperature liquid enters the inside of the covering outer layer 901 from the high-temperature port 902, and low-temperature liquid is discharged from the low-temperature port 903.

[0047] In summary, in the present invention, chemical drugs are first input into the interior of the device main body 1 through the feed port 5. While a series of reactions occur in the internal space, the liquid is filtered by the activated carbon filtering unit below the drive control unit 2, so that the activated carbon and impurities remain on the liquid surface. The required liquid passes through the activated carbon filtering unit and is stirred by the stirring blades 204 at the bottom of the drive control unit 2 below, and is discharged from the water outlet 8. The activated carbon and impurities floating on the liquid surface will gradually float to the bottom of the floating matter suction unit 6 due to the increase in the liquid. The floating matter suction unit 6 will suck the mixed liquid of the activated carbon and impurities on the liquid surface, so as to clean the impurities adsorbed by the activated carbon after filtration. Over time, the effect of the activated carbon filtering unit 4 will decrease due to more and more impurities adsorbed on the filter plate 401. At this time, the filter screen cleaning unit 3 is used to clean the activated carbon filtering unit. During the rotation of the activated carbon filtering unit, the self-cleaning brush belt 308 of the unit will rotate rapidly along with the rotation, so that the filter screen cleaning unit 3 can be quickly cleaned. If the temperature needs to be controlled inside the device main body 1, the temperature control clamping cover unit 9 is used for temperature control, and the high-temperature liquid inside the temperature control cover unit is used for temperature control.
