Description

Technical Field

[0001] This utility model belongs to the field of oral liquid production technology, specifically a cooling device for oral liquid production. Background Technology

[0002] Oral liquid preparations are made from traditional Chinese medicine decoctions, extracting the effective components of the medicine, adding flavoring agents, antibacterial agents and other additives, and following the ampoule filling and sealing process of injection preparations. They are sterile or semi-sterile oral liquid preparations. During the processing of oral liquid preparations, the oral liquid needs to be cooled before filling, thus requiring a cooling device for oral liquid production.

[0003] The existing cooling device for oral liquid production mainly includes: a fixed platform, a support column, a heat absorption cooling mechanism, and a cooling structure. The hydraulic cylinder intermittently pushes the heat exchange ring to rise and fall. During the rising process, the coolant enters the inner side of the heat exchange ring through the inlet hole to absorb heat. When the heat exchange ring falls, the coolant is transferred to the outer side of the baffle ring through the drain hole, and then enters the inner side of the baffle ring through the inlet hole to absorb heat. This cycle repeats to achieve the cooling effect.

[0004] However, existing cooling devices still have some problems. The coolant passes through the first and second cooling coils for cooling, and due to limitations in the ZT value of the thermoelectric materials, the actual cooling power density is typically <0.5 W / cm³. 2 This makes it difficult to meet the rapid cooling requirements of large-volume oral liquids, which leads to a decrease in the cooling efficiency of oral liquids. Therefore, a cooling device for oral liquid production is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a cooling device for oral liquid production.

[0006] The technical solution adopted by this utility model to solve its technical problem is a cooling device for oral liquid production, comprising: a fixed platform, a support column fixedly connected to the upper surface of the fixed platform, a cooling box installed at one end of the support column, a door hinged to the top of the cooling box, a double-layered structure inside the cooling box, a first spiral plate and a second spiral plate installed on the inner wall of the double-layered structure, a water inlet pipe fixedly connected to one side of the cooling box, the water inlet pipe extending into the interior of the double-layered structure, a first water pump installed on the water inlet pipe, and a drain pipe fixedly connected to one side of the cooling box, one end of the drain pipe extending... Extending into the interior of the interlayer, a second water pump is installed on the drain pipe. The second and first water pumps are connected to the outer surface of the cooling box. An inlet pipe is fixedly connected to the top of the cooling box, and an outlet pipe is fixedly connected to the bottom of the cooling box. A control valve is installed on the outlet pipe. The cooling water entering the interlayer flows along the first and second spiral plates, which can increase the flow time of the water in the interlayer and prolong the residence time of the water in the interlayer, thereby further reducing the temperature of the cooling box. The door of the cooling box can reduce or prevent the oxidation and contamination of the oral liquid by the external air environment.

[0007] Preferably, a drive motor is installed on the upper surface of the cooling box, and an agitator is fixedly connected to the output end of the drive motor. The agitator extends into the interior of the cooling box, and a connecting frame is fixedly connected to the agitator. When the drive motor runs, it can drive the agitator to rotate, thereby driving multiple sets of agitator plates to rotate, causing the oral liquid in the cooling box to shake, thereby improving the uniformity of the oral liquid cooling.

[0008] Preferably, a limiting frame is installed on one side of the connecting frame, and an adjusting rod is slidably connected inside the limiting frame. The adjusting rod is located inside the limiting frame, and an adjusting groove is provided on the limiting frame. The limiting frame adjusts the movement range of the adjusting rod to prevent it from falling off.

[0009] Preferably, a first spring is fixedly connected to one end of the adjusting rod, and a positioning frame is fixedly connected to the outside of the adjusting rod. The positioning frame is movably connected inside the adjusting groove. A baffle is hinged to one side of the positioning frame. Magnetic strips are provided inside both the baffle and the limiting frame. When the two sets of magnets attract each other, the position of the positioning frame can be fixed, thereby fixing the stirring plate by the adjusting rod.

[0010] Preferably, a stirring plate is installed at the other end of the adjusting rod. A second spring is fixedly connected inside one side of the stirring plate, and a silicone scraper is fixedly connected to one end of the second spring. The silicone scraper is slidably connected to the inside of the stirring plate. When the stirring shaft rotates, the centrifugal force generated throws the silicone scraper outward, thereby scraping off the oral liquid adhering to the inner wall of the cooling box, making the oral liquid in the cooling box cool more evenly.

[0011] Preferably, the cooling device is externally connected to a controller, which is used to control the start and stop of the first water pump, the second water pump, the control valve, and the drive motor. By controlling the first water pump, the second water pump, the control valve, and the drive motor through the external controller, the ease of use of the cooling device is improved.

[0012] The advantages of this invention are as follows: the cooling water entering the interlayer flows along the first and second spiral plates, which increases the flow time and residence time of the water in the interlayer. The second water pump is started by an external controller to draw the water with increased temperature out of the interlayer. In conjunction with the inlet pipe and the first water pump, the water inside the interlayer is kept in a flowing state, thereby ensuring that the water inside the interlayer is always kept at a low temperature. This improves the cooling efficiency of the oral liquid inside the cooling box and thus improves the production efficiency of the oral liquid.

[0013] This invention, by changing the tilt angle of the stirring plate, can stir oral liquids of different concentrations without altering their original colloidal structure. Furthermore, the silicone scraper, driven by the stirring shaft, adheres to the inner wall of the cooling box, scraping off the oral liquid adhering to the inner wall, resulting in more uniform cooling of the oral liquid within the cooling box and thus improving the practicality of the cooling device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 As shown, a cooling device for oral liquid production includes: a fixed platform 1, a support column 2 fixedly connected to the upper surface of the fixed platform 1, a cooling box 3 installed at one end of the support column 2, a door hinged to the top of the cooling box 3, a double-layer 4 opened inside the cooling box 3, a first spiral plate 5 and a second spiral plate 6 installed on the inner wall of the double-layer 4, a water inlet pipe 7 fixedly connected to one side of the cooling box 3, the water inlet pipe 7 extending into the interior of the double-layer 4, a first water pump 8 installed on the water inlet pipe 7, a drain pipe 9 fixedly connected to one side of the cooling box 3, one end of the drain pipe 9 extending into the interior of the double-layer 4, a second water pump 10 installed on the drain pipe 9, the second water pump 10 and the first water pump 8 connected to the outer surface of the cooling box 3, a liquid inlet pipe 11 fixedly connected to the top of the cooling box 3, a liquid outlet pipe 12 fixedly connected to the bottom of the cooling box 3, and a control valve installed on the liquid outlet pipe 12;

[0023] In the processing of oral liquid preparations, the oral liquid needs to be cooled before filling. To improve the cooling efficiency of the oral liquid and thus increase the production efficiency, a cooling device for oral liquid production is proposed. In actual use, an external water pipe is connected to the inlet pipe 7, and then the first water pump 8 is started through the external controller to pump low-temperature water from the external water pipe into the jacket 4, filling the interior of the jacket 4. During filling, the water flows along the first spiral plate 5 and the second spiral plate 6, which increases the flow time of the water in the jacket 4 and prolongs the residence time of the water in the jacket 4. Over time, the internal temperature of the cooling tank 3 is further reduced. Then, the second water pump 10 is started by the external controller to draw out the water with the increased temperature in the jacket 4. The drain pipe 9 is located above the inlet pipe 7. In cooperation with the inlet pipe 7 and the first water pump 8, the water inside the jacket 4 is kept in a flowing state, thereby ensuring that the water inside the jacket 4 is always kept at a low temperature. When the cooling water is drawn out by the second water pump 10, the water level is located at a higher position in the jacket 4, so that the cooling water can surround the oral liquid in the cooling tank 3, thereby improving the cooling efficiency of the oral liquid and thus improving the production efficiency of the oral liquid.

[0024] Please see Figure 1-5 As shown, a drive motor 13 is mounted on the upper surface of the cooling box 3. An agitator shaft 14 is fixedly connected to the output end of the drive motor 13. The agitator shaft 14 extends into the interior of the cooling box 3. A connecting frame 15 is fixedly connected to the agitator shaft 14. A limit frame 16 is mounted on one side of the connecting frame 15. An adjusting rod 17 is slidably connected inside the limit frame 16. The adjusting rod 17 is located inside the limit frame 16. An adjusting groove 18 is provided on the limit frame 16. A first spring 19 is fixedly connected to one end of the adjusting rod 17. A positioning frame 20 is fixedly connected to the outer side of the adjusting rod 17. The 0 is connected to the inside of the adjusting groove 18. A baffle 21 is hinged to one side of the positioning frame 20. Magnetic strips 22 are provided inside both the baffle 21 and the limiting frame 16. A stirring plate 23 is installed at the other end of the adjusting rod 17. A second spring 24 is fixedly connected inside one side of the stirring plate 23. A silicone scraper 25 is fixedly connected to one end of the second spring 24. The silicone scraper 25 is slidably connected to the inside of the stirring plate 23. The cooling device is externally connected to a controller, which is used to control the start and stop of the first water pump 8, the second water pump 10, the control valve, and the drive motor 13.

[0025] Adjust the stirring angle of the stirring plate 23 according to the viscosity of the oral liquid. Open the door of the cooling box 3, then pry the baffle 21 outward with the hinge as the axis to release the fixation of the positioning frame 20. Push the stirring plate 23 and the adjusting rod 17 into the limiting frame 16, while simultaneously squeezing the first spring 19. Rotate the stirring plate 23 to drive the positioning frame 20 to rotate along the adjusting groove 18, thereby changing the tilt angle of the stirring plate 23. After adjusting to a suitable angle, make the crossbar of the positioning frame 20 and the... With the grooves of the adjusting groove 18 facing each other, release the pressure on the stirring plate 23. Under the action of the elastic force of the first spring 19, push the positioning frame 20 into the adjusting groove 18 to fix the angle of the stirring plate 23. Then rotate the baffle 21 in the opposite direction so that the two sets of magnetic strips 22 attract each other, thus fixing the position of the positioning frame 20. This, in turn, fixes the stirring plate 23 through the adjusting rod 17. This allows the adjusted stirring plate 23 to adjust the concentration of different oral liquids without changing the original colloidal structure. When the oral liquid is agitated and the tilt angle of the agitator 23 is small, a high axial flow is generated, which pushes the oral liquid to circulate up and down along the inner wall of the cooling tank 3, eliminating vertical temperature stratification. When the tilt angle of the agitator 23 is large, the radial flow is enhanced, forming strong shear turbulence, which quickly breaks the thermal boundary layer. After the angle of the agitator 23 is adjusted, the door is closed, so that the cooling tank 3 is in a closed state. The drive motor 13 is started by the external controller, which drives the agitator shaft 14 to rotate. The centrifugal force generated when the agitator shaft 14 rotates throws the silicone scraper 25 outward, so that the second spring 24 is stretched outward, so that the silicone scraper 25 can stick to the inner wall of the cooling tank 3, thereby scraping off the oral liquid adhering to the inner wall of the cooling tank 3, making the cooling of the oral liquid in the cooling tank 3 more uniform, thus improving the practicality of the cooling device. After the oral liquid is cooled, the control valve is started by the external controller, so that the liquid outlet pipe 12 is in an open state, and the cooled oral liquid in the cooling tank 3 can be collected.

[0026] Working principle: Based on the viscosity of the oral liquid, the stirring angle of the stirring plate 23 is adjusted. The door of the cooling tank 3 is opened, and the stirring plate 23 and adjusting rod 17 are pushed into the limiting frame 16, compressing the first spring 19. Rotating the stirring plate 23 causes the positioning frame 20 to rotate along the adjusting groove 18, thus changing the tilt angle of the stirring plate 23. After adjusting to a suitable angle, the crossbar of the positioning frame 20 aligns with the groove of the adjusting groove 18. The pressure on the stirring plate 23 is released, and under the elastic force of the first spring 19, the positioning frame 20 is pushed into the adjusting groove 18, fixing the angle of the stirring plate 23. Then, the baffle 21 is rotated in the opposite direction, causing the two sets of magnetic strips 22 to attract each other, thereby fixing the stirring plate 23 through the adjusting rod 17. This allows the adjusted stirring plate 23 to maintain the original viscosity of the oral liquid without altering its properties. In the presence of a colloidal structure, oral liquids of varying concentrations are stirred. The first water pump 8 is activated via an external controller, drawing low-temperature water from the external water pipe into the jacket 4, thus lowering the internal temperature of the cooling tank 3. Subsequently, the second water pump 10 is activated via the external controller, drawing the heated water from the jacket 4 outwards. This, in conjunction with the inlet pipe 7 and the first water pump 8, keeps the water in the jacket 4 in a flowing state, ensuring that the water in the jacket 4 remains at a low temperature. This improves the cooling efficiency of the oral liquids inside the cooling tank 3. The oral liquids to be cooled are then poured into the cooling tank 3 through the outlet pipe 12 for cooling. After the oral liquids have cooled, the control valve is activated via the external controller, opening the outlet pipe 12 to collect the cooled oral liquids from the cooling tank 3.
