Description

Technical Field

[0001] The invention relates to the technical field of glucose storage, in particular to a glucose storage device. Background Art

[0002] Glucose is a water-soluble, sweet, colorless monosaccharide that is widely distributed in nature. It plays an important role in the human body, quickly replenishing energy, promoting liver detoxification, and enhancing memory. Glucose is one of the most abundant and important monosaccharides in nature. This monosaccharide is not only found in grapes and other sweet fruits, but is also widely distributed in plants and animals.

[0003] When storing glucose in large quantities, a dedicated storage device is usually required. However, when storing glucose, powdered glucose easily absorbs moisture and forms lumps. Since the agglomerated glucose may absorb moisture or other impurities during storage, its chemical properties may change. If it is not screened during storage, the purity and stability of the entire tank of glucose may be affected. However, existing glucose storage devices are usually one-piece tanks that lack a screening device. If one wants to screen the agglomerated glucose during storage, the entire tank of glucose needs to be poured out for screening, which is time-consuming and labor-intensive. In addition, existing storage devices lack a disinfection mechanism. When glucose is used as an edible or medical product, its sterility needs to be ensured. If the glucose is not disinfected during storage, it is easy for the glucose to be contaminated, affecting its safe use. Summary of the invention

[0019] In the present embodiment, during use, the powdered glucose to be stored can be added into the storage tank 3 through the feeding port 5. When more than half of the glucose is stored in the storage tank 3, the operator can close the feeding port 5 and let the storage tank 3 be stored statically. During the process of storing glucose in the storage tank 3, the operator can periodically turn on the starting motor 2 to drive the storage tank 3 to rotate slowly. When the storage tank 3 rotates, the glucose stored inside it will be turned over. Since the storage tank 3 is not full of glucose, when the storage tank 3 rotates, the glucose will continuously pass through the sieve plate 16 to be turned over. After the glucose passes through the sieve plate 16 with larger filter holes, it will be filtered by the inner plate 18 with smaller filter holes inside the sieve plate 16. If the glucose particles are normal, the glucose will pass through the sieve plate 16 and the inner plate 18 normally. If the glucose clumps during storage, the glucose blocks with larger particles will be blocked on the surface of the sieve plate 16 with smaller pores. Since the entire storage tank 3 is slightly tilted, the glucose blocks left on the surface of the inner plate 18 will The glucose will slide down the inclined inner plate 18 into the guide member 6, and then enter the rotating rod 8 through the conveying of the guide member 6. The glucose entering the rotating rod 8 will fall into the processing tank 9 through the discharge hole 10. Since the rotating rod 8 is connected to the guide member 6, when the storage tank 3 rotates, the rotating rod 8 will be driven to rotate synchronously. When the rotating rod 8 rotates, the driving wheel 11 will be rotated through the transmission wheel 12 and the belt 13. Since the wheel diameter of the driving wheel 11 is much smaller than the transmission wheel 12, when the transmission wheel 12 rotates at a slower speed, the driving wheel 11 will rotate. When rotating, the driving wheel 11, driven by the belt 13, will cause the driving rod to rotate rapidly. When the driving rod rotates rapidly, the multiple crushing blades 14 fixed on the driving rod will rotate rapidly to re-crush the agglomerated glucose falling from the discharge hole 10. The re-crushed glucose will enter the storage box 43 through the conduit 15 for re-storage. If the glucose in the storage box 43 can be used normally, it can be taken out from the storage box 43 for use to avoid waste. If it cannot be used, it can be taken out and poured out.

[0020] Example 2: Please refer to Figure 1 - Fig. 9In the figure, the circulating disinfection mechanism includes a vent head 23 arranged inside the heating box 17, the end of the vent head 23 is connected to a circulation pipe 24, the circulation pipe 24 is slidably connected with a plurality of slide rods 25, the ends of the plurality of slide rods 25 are all extended to the outside of the circulation pipe 24, the interiors of the plurality of slide rods 25 are provided with air outlet holes 26, the ends of the plurality of slide rods 25 are provided with pressing plates 29, the pressing plates 29 are provided with pushing magnetic blocks 27, two outer walls of the plurality of slide rods 25 are sleeved with pressing springs 28, the interior of the heating box 17 is connected to a disinfection pipe 30, the interior of the disinfection pipe 30 is provided with a plurality of spray tubes 32, the interiors of the plurality of spray tubes 32 are provided with air suction holes 33, the interiors of the plurality of spray tubes 32 are connected to an air jet pipe 3 1. The jet pipe 31 penetrates to the outside of the disinfection tube 30, and the interiors of the multiple spray tubes 32 are all slidably connected with piston rods 35, and two of the multiple piston rods 35 are sleeved with return springs 36 on the outside. A push plate 34 is provided at the end of the piston rod 35, and both sides of the push plate 34 are fixedly connected with trigger magnetic blocks 41. A slide plate 37 is fixedly connected to the inside of the storage tank 3, and a driving member 38 is slidably connected to the outer wall of the slide plate 37. The interior of the driving member 38 is slidably connected with a sliding magnet 42, and the interior of the driving member 38 is fixedly connected with an electric telescopic rod 40. The other end of the electric telescopic rod 40 is fixedly connected to the outer wall of the sliding magnet 42, and a contact head 39 is fixedly connected to the outer wall of the driving member 38. The contact head 39 is located on the positive side of the knocking rod 21.

[0021] In this embodiment, when the storage tank 3 rotates, in addition to turning over the glucose inside it, it also drives the heating box 17 to rotate together. When the storage tank 3 drives the heating box 17 to rotate to the original position of the feeding port 5, the driving member 38 at this time will move along the slide plate 37 under the action of its own gravity and come to the positive side of the pushing magnetic block 27. Since the magnetic poles of the pushing magnetic block 27 and the sliding magnet 42 are opposite, when the sliding magnet 42 is located on the positive side of the pushing magnetic block 27, under the action of the magnetic force of attraction, the pressing plate 29 will overcome the elastic force of the pressing spring 28 and drive The plurality of slide bars 25 move toward the direction approaching the slide plate 37, so that the plurality of air outlets 26 originally located in the circulation tube 24 move out of the circulation tube 24. When the plurality of air outlets 26 are located outside the circulation tube 24, the air heated by the heater in the heating box 17 will first enter the circulation tube 24, then enter the slide bar 25 through the open end of the slide bar 25, and finally enter the storage tank 3 through the leaking air outlets 26, thereby heating the storage tank 3. By introducing heated dry air, the dryness of the entire tank body is ensured, thereby preventing glucose from agglomerating due to moisture in the storage tank 3.

[0022] During the flipping process of the storage tank 3, if it is necessary to disinfect the storage tank 3, the operator can extend the electric telescopic rod 40 to make the sliding magnet 42 slide in the direction close to the push plate 34. After the sliding magnet 42 slides in the direction close to the push plate 34, when the storage tank 3 is flipped to allow the heating box 17 to rotate to the original position of the feeding port 5, the driving member 38 will slide in the direction close to the pushing magnet block 27 under the action of its own gravity. In the process of the sliding magnet 42 driven by the driving member 38, it will be located on the positive side of the two triggering magnet blocks 41 successively. Since the magnetic poles of the driving member 38 and the triggering magnet block 41 are the same, when the driving member 38 is located on the positive side of the first triggering magnet block 41, under the action of the repelling magnetic force, the triggering magnet block 41 will push the piston rod 35 into the spray barrel 32, and the ozone sucked in the spray barrel 32 will be sprayed out through the jet pipe 31, The storage tank 3 is disinfected, and when the driving member 38 is away from the positive side of the first trigger magnetic block 41, the push plate 34 will drive the piston rod 35 to move towards the slide plate 37 under the elastic force of the return spring 36, so that the piston rod 35 returns to its original position. When the piston rod 35 returns to its original position, the ozone circulating in the disinfection tube 30 will be sucked through the suction hole 33, which is convenient for next use (it should be noted that both the jet pipe 31 and the suction hole 33 are provided with a one-way valve to ensure that the jet pipe 31 only sprays air and the suction hole 33 only inhales air). When the driving member 38 drives the sliding magnet 42 to move to the end of the slide plate 37, the sliding magnet 42 is located at the positive side of the second trigger magnetic block 41. Under the above principle, the spray gun 32 will spray ozone into the storage tank 3 again for disinfection. By introducing ozone into the storage tank 3 for disinfection, the safety of the glucose stored in the storage tank 3 can be guaranteed.

[0023] It should be noted that when the electric telescopic rod 40 contracts and the sliding magnet 42 moves toward the direction of the pushing magnet 27, the sliding magnet 42 will be farther away from the triggering magnet 41. Even when the driving member 38 drives the sliding magnet 42 to the positive side of the triggering magnet 41, the triggering magnet 41 and the sliding magnet 42 will not generate a repulsive magnetic force. On the contrary, when the electric telescopic rod 40 is extended and the sliding magnet 42 moves toward the direction of the triggering magnet 41, the sliding magnet 42 is farther away from the pushing magnet 27. Even when the sliding magnet 42 moves to the positive side of the pushing magnet 27, the attractive magnetic force generated cannot pull the multiple sliding rods 25 toward the slide plate 37. Under the above principle, it can be achieved that when dry air is introduced, the spray gun 32 will not spray ozone outward, and when the spray gun 32 sprays ozone, the sliding rod 25 will not introduce hot air into the storage tank 3.

[0024] It should be noted that when the slide bar 25 is triggered to let hot air in, the temperature of the air in the circulation pipe 24 is higher than that in the storage tank 3. When the air is heated and dried, its temperature increases, which will cause the relative humidity to decrease, thereby reducing the air density, while the air in the storage tank 3 is relatively normal. According to the principles of thermodynamics, hot air usually flows in the direction of lower temperature to form a convection cycle. Therefore, when the slide bar 25 is pulled toward the slide plate 37, the hot air in the circulation pipe 24 will flow into the storage tank 3 through the slide bar 25. When hot air circulates in the storage tank 3, the solenoid valve in the vent valve port 4 can be opened to discharge the original air in the storage tank 3 to achieve circulation.

[0025] It should be noted that the storage tank 3 is constantly rotating, so the position of the slide plate 37 will keep changing. Therefore, when the storage tank 3 rotates, the driving member 38 will keep sliding up and down on the slide plate 37. When the slide plate 37 slides up and down, it can not only rely on the magnetic force to continuously introduce hot air or ozone into the storage tank 3, but also drive the contact head 39 to continuously contact and knock the knocking rod 21. Since the knocking rod 21 is connected to the inner plate 18, when the knocking rod 21 is knocked, under the action of multiple vibration springs 20, the inner plate 18 will vibrate in the chute 19. When the inner plate 18 vibrates, it can not only improve the screening efficiency, but also allow the agglomerated glucose remaining on the surface of the inner plate 18 to enter the material guide 6 faster along the inclined inner plate 18.

[0026] It should be noted that when the storage tank 3 is stationary and does not rotate, the operator can rotate the storage tank 3 again so that the feeding port 5 faces upward. Figure 1 As shown in FIG. 1 , when the feed port 5 is facing upward and the heating box 17 is facing downward, the driving member 38 is located below the slide plate 37. Fig. 9 As shown, at this time, the sliding magnet 42 is away from the pushing magnet block 27 and the triggering magnet block 41 , so the circulation pipe 24 and the disinfection pipe 30 will not pass ozone and hot air into the storage tank 3 .

[0027] It should be noted that ozone, as a strong oxidant, achieves its bactericidal effect by destroying the cell structure of microorganisms. In addition, ozone will quickly decompose into oxygen during the disinfection process without secondary pollution, making it suitable for the disinfection of sensitive substances such as glucose.

[0028] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
