Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, and specifically relates to a decolorization reaction vessel for processing sodium gluconate. Background Technology

[0002] In the fermentation process of sodium gluconate production, the crude product often contains yellowish-brown pigment, which needs to be decolorized to improve the purity of the product. Therefore, a decolorization reactor is required.

[0003] For example, Chinese patent CN221933912U discloses a fish oil decolorization reactor, which relates to the field of fish oil decolorization equipment technology. It improves upon the problems of existing fish oil decolorization reactors where the heating plate is installed inside the activation box by fixing bolts. When the heating plate needs to be repaired or replaced due to damage, external tools are required to disassemble the heating plate inside the activation box, which is relatively troublesome and has limited operating space. The new reactor includes a reactor body and an activation box set on the reactor body. The reactor body and the activation box are connected by a connecting pipe, and a solenoid valve is installed on the connecting pipe.

[0004] The aforementioned decolorizing reactor can decolorize fish oil. However, this decolorizing reactor has some defects that need to be improved. Existing equipment usually only uses a single stirring rod to mix the material and the decolorizing agent, which results in insufficient contact between the material and the decolorizing agent, leading to uneven mixing in some areas and low utilization of the decolorizing agent. In addition, solid particles such as decolorizing agent residue and oil oxidation impurities are generated during the decolorization process. These particles are discharged through the impurity discharge port of the decolorizing reactor, but some particles adhere to the liquid discharge port of the decolorizing reactor, which can easily cause the collected liquid to be discharged poorly. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a decolorization reaction vessel for processing sodium gluconate, so as to solve the problems in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A decolorizing reactor for processing sodium gluconate includes a reactor body, a controller fixedly connected to one side of the reactor body, an electric heating plate fixedly connected to the periphery of the reactor body, a waste discharge pipe fixedly connected to the bottom of the reactor body, a drain pipe fixedly connected to one side of the reactor body, a drain port opened inside the reactor body, the drain pipe communicating with the drain port, a material inlet pipe fixedly connected to one side of the top of the reactor body, an additive inlet pipe fixedly connected to the other side of the top of the reactor body, a drive assembly provided at the middle of the top of the reactor body, a stirring assembly rotatably connected inside the reactor body via the drive assembly, a scraper assembly provided on one side of the stirring assembly, and one side of the scraper assembly movably connected to the drain port.

[0007] As a preferred technical solution, a box is fixedly connected to one side of the drain pipe, and a filter screen is slidably connected inside the box.

[0008] As a preferred technical solution, the driving component includes a motor, which is fixedly connected to the upper side of the reactor body. A drive gear is fixedly connected to the output end of the motor, and driven gears are meshed on both sides of the drive gear. Both the drive gear and the driven gears are fixedly connected to the stirring component. Both the drive gear and the driven gears are rotatably connected to the upper side of the reactor body. A bracket is fixedly connected to the upper side of the reactor body, and the motor is fixedly connected to the bracket.

[0009] As a preferred technical solution, the stirring assembly includes a spiral stirring blade, which is fixedly connected to the bottom end of the driving gear. A stirring plate is fixedly connected to the bottom end of the driven gear. Both the stirring plate and the spiral stirring blade are rotatably connected inside the reactor body. A cross stirring frame is fixedly connected to the bottom end of the spiral stirring blade.

[0010] As a preferred technical solution, a fixing ring is fixedly connected to the outer side of the cross-shaped stirring frame, and the scraping assembly is fixedly connected to both sides of the fixing ring.

[0011] As a preferred technical solution, the scraping assembly includes a shock absorber, which is fixedly connected to both sides of the fixed ring. A scraper plate is fixedly connected to one end of the shock absorber. The scraper plate is intermittently movably connected to the drain port. A rubber sleeve is fixedly connected between the scraper plate and the fixed ring. The rubber sleeve is fitted on the outside of the shock absorber. The shock absorber is composed of a shock-absorbing spring and a damper.

[0012] In summary, the present invention has the following main advantages: First, this utility model controls the operation of the stirring component through a drive component. After the motor starts, it drives the active gear to rotate. The active gear drives the driven gears on both sides to rotate synchronously through meshing. This causes the spiral stirring blade at the bottom of the active gear and the stirring plate at the bottom of the driven gear to form a linkage stirring. At the same time, the cross stirring frame rotates. When the spiral stirring blade rotates, it can drive the material in the vessel to circulate and tumble along the axial direction, conveying the lower part of the sodium gluconate solution upward. Meanwhile, the stirring plates on both sides disperse the material laterally along the radial direction. Together with the cross stirring frame at the bottom of the spiral stirring blade, it stirs the bottom of the vessel, forming a multi-dimensional three-dimensional stirring effect. This allows the sodium gluconate solution to fully contact and collide with the decolorizing agent, avoiding local mixing dead zones and improving the adsorption efficiency of the decolorizing agent on pigments. Secondly, in this utility model, when the driving component drives the stirring component to rotate, it simultaneously drives the scraping component to rotate. When the scraping plate rotates to the position of the drain port, the elastic effect of the shock absorber pushes the scraping plate to adhere to the inner wall of the drain port, which significantly reduces the decolorizing agent residue at the drain port. No additional power is required to continuously clean the impurities at the drain port, which facilitates subsequent draining. Attached Figure Description

A controller 2 is fixedly connected to one side of the reactor body 1, and an electric heating plate 3 is fixedly connected to the periphery of the reactor body 1. A waste discharge pipe 5 is fixedly connected to the bottom of the reactor body 1, and a drain pipe 4 is fixedly connected to one side of the reactor body 1. Electromagnetic valves are installed at both the drain pipe 4 and the waste discharge pipe 5. A drain port 6 is provided inside the reactor body 1, and the drain pipe 4 is connected to the drain port 6. A material inlet pipe 10 is fixedly connected to one side of the top of the reactor body 1, and an additive inlet pipe 11 is fixedly connected to the other side of the top of the reactor body 1. A drive assembly 9 is provided at the center of the top of the reactor body 1. Inside the main body 1, a stirring assembly 12 is rotatably connected via a drive assembly 9. A scraper assembly 13 is provided on one side of the stirring assembly 12, and one side of the scraper assembly 13 is movably connected to the drain port 6. During operation, crude sodium gluconate solution is injected into the reactor body 1 through the material inlet pipe 10, and decolorizing agent is added through the additive inlet pipe 11. The controller 2 activates the electric heating plate 3 to adjust the temperature inside the reactor to a suitable range. At the same time, the drive assembly 9 is activated to drive the stirring assembly 12 to achieve material mixing and decolorization. The scraper assembly 13 simultaneously cleans impurities from the drain port 6. After decolorization, the solution is discharged through the drain port 6 and the drain pipe 4, and the impurities are discharged through the impurity discharge pipe 5. The overall structure is adapted to the processing requirements of sodium gluconate and solves the problems of uneven mixing and poor drainage in traditional equipment.

[0021] refer to Figure 1 A box 7 is fixedly connected to one side of the drain pipe 4, and a filter screen 8 is slidably connected inside the box 7. During the solution discharge process, the filter screen 8 performs secondary filtration on the solution to intercept fine impurities and improve purity. When a lot of impurities accumulate on the surface of the filter screen 8, the filter screen 8 can be directly pulled out from the box 7 for cleaning or replacement.

[0022] refer to Figure 2 The drive assembly 9 includes a motor 91, which is fixedly connected to the upper side of the reactor body 1. A drive gear 92 is fixedly connected to the output end of the motor 91. Driven gears 93 are meshed on both sides of the drive gear 92. Both the drive gear 92 and the driven gears 93 are fixedly connected to the stirring assembly 12. Both the drive gear 92 and the driven gears 93 are rotatably connected to the upper side of the reactor body 1. A bracket 94 is fixedly connected to the upper side of the reactor body 1, and the motor 91 is fixedly connected to the bracket 94. The controller 2 controls the motor 91 to start. The output end of the motor 91 drives the drive gear 92 to rotate. The drive gear 92 drives the driven gears 93 on both sides to rotate synchronously, thereby driving the stirring assembly 12 to rotate and providing power support.

[0023] refer to Figure 3The stirring assembly 12 includes a spiral stirring blade 121, which is fixedly connected to the bottom end of the driving gear 92. A stirring plate 122 is fixedly connected to the bottom end of the driven gear 93. Both the stirring plate 122 and the spiral stirring blade 121 are rotatably connected inside the reactor body 1. A cross stirring frame 123 is fixedly connected to the bottom end of the spiral stirring blade 121. The driving gear 92 drives the spiral stirring blade 121 to rotate, causing the material in the reactor to circulate axially up and down. The driven gear 93 drives the stirring plate 122 to radially disperse the material, while the cross stirring frame 123 stirs the material at the bottom of the reactor. The three components form a multi-dimensional stirring system, which effectively improves the mixing uniformity of the material and the decolorizing agent, avoids local mixing dead zones, and improves the decolorization efficiency.

[0024] refer to Figure 4 A fixing ring 124 is fixedly connected to the outer side of the cross-shaped stirring frame 123, and the scraping assembly 13 is fixedly connected to both sides of the fixing ring 124. When the cross-shaped stirring frame 123 rotates, it drives the fixing ring 124 to rotate synchronously. The fixing ring 124 provides installation support for the scraping assembly 13 and transmits the power of the stirring assembly 12 to the scraping assembly 13, so that the scraping assembly 13 operates synchronously with the stirring action, realizing the linkage between stirring and scraping. There is no need to set up an additional scraping power source, simplifying the equipment structure and reducing energy consumption.

[0025] refer to Figure 3 The scraping assembly 13 includes a shock absorber 133, which is fixedly connected to both sides of the fixing ring 124. A scraper plate 131 is fixedly connected to one end of the shock absorber 133. The scraper plate 131 is intermittently movably connected to the drain port 6. A rubber sleeve 132 is fixedly connected between the scraper plate 131 and the fixing ring 124. The rubber sleeve 132 is fitted over the outside of the shock absorber 133. The shock absorber 133 consists of a shock-absorbing spring and a damper. The fixing ring 124... 24 drives the shock absorber 133 and scraper 131 to make circular motion. When the scraper 131 approaches the drain port 6, the shock-absorbing spring of the shock absorber 133 pushes the scraper 131 to stick to the inner wall of the drain port 6 to scrape away impurities, thus buffering the impact force during scraping. When the scraper 131 moves away from the drain port 6, the material resistance causes the shock absorber 133 to contract and reset. The rubber sleeve 132 prevents the material from entering the interior of the shock absorber 133, ensuring the stable operation of the scraper assembly 13 and continuously ensuring the unobstructed flow of the drain port 6.

[0026] Operating principle and advantages: First, the crude sodium gluconate solution to be decolorized is injected into the reactor body 1 through the material inlet pipe 10. Then, decolorizing agents such as activated carbon are added through the additive inlet pipe 11. Subsequently, the electric heating plate 3 is activated by the controller 2 to adjust the temperature inside the reactor to 50-60℃, a suitable range for sodium gluconate decolorization and resistance to degradation. Next, the motor 91 in the drive assembly 9 is activated, driving the drive gear 92 to rotate. The drive gear 92 synchronously drives the driven gears 93 on both sides to rotate through meshing. The drive gear 92 drives the spiral stirring blades 121 to rotate, causing the material inside the reactor to circulate axially up and down. The driven gears 93 drive the stirring plate 122 to radially disperse the material, while the cross stirring frame 123 stirs the material at the bottom of the reactor. The three form a multi-dimensional stirring system. This effectively improves the uniformity of mixing between materials and decolorizing agent, avoids localized mixing dead zones, and enhances decolorization efficiency. Simultaneously, the scraping component 13 works synchronously with the stirring component 12. The fixing ring 124 drives the shock absorber 133 and the scraper 131 to perform circular motion. When the scraper 131 approaches the drain port 6, the shock-absorbing spring of the shock absorber 133 pushes the scraper 131 to adhere to the inner wall of the drain port 6 to scrape away impurities, thus buffering the impact force during scraping. After stirring and decolorizing for 30-40 minutes, stop stirring and let it stand for 10 minutes. Open the drain pipe 4 valve to allow the decolorized sodium gluconate solution to be discharged after being filtered through the drain port 6 and the filter screen 8. Finally, after the solution is drained, open the impurity discharge pipe 5 valve to discharge the large amount of settled impurities. When there is a large accumulation of impurities on the filter screen 8, it can be directly pulled out of the box 7 for cleaning or replacement.
