Description

Technical Field

[0001] This utility model relates to the field of heparin calcium concentration technology, specifically a heparin calcium concentration device. Background Technology

[0002] A condenser must be connected during vacuum evaporation because its function is to condense the vapor produced during evaporation into liquid, preventing it from returning to the evaporator or polluting the environment. Furthermore, the condenser ensures the system's vacuum level, guaranteeing smooth evaporation. To ensure efficient condenser operation, its inlet gas temperature should be maintained within a suitable range. Specifically, the optimal operating temperature of the condenser should be within the temperature range that condenses gas or vapor into liquid, while keeping the pressure difference between the evaporator and condenser from being too large. For direct condensers, the temperature should be sufficient to completely condense the gas / vapor into liquid at a given pressure; for indirect condensers, a suitable medium needs to be selected based on specific requirements to ensure a balance between heat exchange efficiency and energy consumption.

[0003] As discussed above, when a condenser condenses a gas, the gas needs to enter at a certain temperature to achieve optimal condensation. Similarly, heparin calcium solution requires a suitable temperature to be stable; excessively high temperatures can affect the quality of heparin calcium and even cause it to lose its activity, rendering it ineffective. However, the temperature of the evaporated liquid during vacuum evaporation of heparin calcium is relatively low, preventing the vapor from achieving optimal heat exchange with the condenser and thus reducing the rate of moisture liquefaction in the gas. Therefore, we propose a heparin calcium concentration device. Utility Model Content

Detailed Implementation

[0023] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1 to 6 This utility model provides a technical solution: a heparin calcium concentration device, including a tank 1, with multiple first legs 12 on the side of the tank 1, a spherical bottom structure, a discharge valve 17 at the bottom of the tank 1, and a top cover 3 installed on the top of the tank 1. The edge of the top cover 3 is fastened to the tank 1 by bolts or the two are connected by a locking buckle. The top cover 3 has at least one feed port 15, and the top of the feed port 15 has a removable sealing cover. The top cover 3 is connected to a vacuum device, which includes a vacuum pump 18. The air inlet of the vacuum pump 18 is connected to the top cover 3 through a pipe, and an electrically controlled valve is installed on the pipe. The electrically controlled valve starts and stops synchronously with the vacuum pump 18. That is, when the vacuum pump 18 is working, the electrically controlled valve also opens, and when the vacuum pump 18 is shut down, the electrically controlled valve also closes. When the vacuum pump 18 is working, the inside of the tank is evacuated to a vacuum.

[0025] A heat preservation cabinet 10 is provided on one side of the tank body 1. The heat preservation cabinet 10 is equipped with a heating channel, and a second heating element 24 is provided on the heating channel. Figure 4 and Figure 5 As shown, the heating channel includes multiple heating tubes 23 arranged at intervals. Adjacent heating tubes 23 are connected by elbows 27. During installation, a second heating element 24 is placed on each heating tube 23, thus forming an S-shaped channel. The second heating element 24 heats the heating tubes 23 to a preset temperature. One end of each heating tube 23 in the heating channel is connected to the top cover 3 via a third conduit 14, and the other end of the heating channel is connected to the air inlet of the condenser 5 via a second conduit 22. The air outlet of the condenser 5 is connected to the top cover 3 via a first conduit 6. like Figure 2 As shown, a sealing plate 20 is detachably provided on one side of the heat preservation cabinet 10, and brackets 13 are provided on both sides of the bottom of the heat preservation cabinet 10. The edge of the heat preservation cabinet 10 is fastened to the heat preservation cabinet 10 by bolts. When the sealing plate 20 is opened, it is convenient to maintain and repair the inside of the heat preservation cabinet 10. It should be noted that when the vacuum pump 18 is evacuated, the heparin calcium solution inside it boils. The liquid that evaporates from the boiling will be sent into each heating tube 23 through the third conduit 14. Since the heating tube 23 is heated by the second heating body 24, the gas passing through the heating tube 23 is also heated. Moreover, the heating tube 23 is long enough to ensure that the gas is fully heated. The heated gas still contains a lot of moisture. When the gas enters the condenser 5 through the second conduit 22, the condenser 5 liquefies the heated gas. Since the gas is preheated, the hotter gas comes into contact with the condenser 5, which makes it easier to liquefy the moisture, thereby removing the moisture from the gas. The cooled gas is then circulated back into the tank 1 through the top cover 3 via the first conduit 6.

[0026] Furthermore, the liquid outlet of the condenser 5 is connected to the liquid collection device, such as... Figure 1 and Figure 4 As shown, the liquid collection device includes a collection tank 7, a drain valve 21 at the bottom of the collection tank 7, multiple second legs 8 at the bottom edge of the collection tank 7, and a fourth conduit 9 at the top of the collection tank 7, which is connected to the liquid outlet of the condensing device 5. Therefore, the liquefied liquid in the condensing device 5 will flow into the collection tank 7 for storage through the fourth conduit 9. It should be noted that the drain valve 21 is closed when the equipment is working, because the condensing device 5, the tank 1, and the collection tank 7 are all in a vacuum state during operation. If the drain valve 21 is not closed, outside air will enter.

[0027] Furthermore, such as Figure 3 and Figure 5As shown, a first heating element 19 is provided on the outside of the spherical structure, and a sealing cover 16 is provided on the outside of the first heating element 19. The first heating element 19 can heat the bottom of the tank 1. Because when heparin calcium is vacuum evaporated, both evaporation and vacuuming cool the tank. However, the evaporation temperature needs to be controlled within a certain temperature range. Therefore, when the temperature inside the tank 1 is lower than the preset value, the tank can be heated by the first heating element 19 to keep the vacuum evaporation in a highly efficient state.

[0028] Furthermore, in order to accelerate the evaporation of the heparin calcium solution in the tank by tumbling, a drive motor 4 is provided at the middle of the top of the top cover 3. A stirring shaft is coaxially mounted on the shaft of the drive motor 4. The stirring shaft is coaxially placed inside the tank 1 and has multiple stirring blades 25. An arc-shaped stirring blade 26 is provided at the bottom of the stirring shaft. The arc-shaped stirring blade 26 is placed inside the spherical structure. The arc-shaped stirring blade 26 is mainly used to scoop up the heparin calcium solution on the inner surface of the spherical structure to prevent the heparin calcium solution from adhering. At the same time, it can eliminate foam during stirring.

[0029] Based on the above embodiments, it should be noted that this application also includes a control cabinet 11, which can be installed on the bracket 13. The control cabinet 11 is equipped with a controller, which is electrically connected to the drive motor 4, the first heating element 19, the second heating element 24, the electric control valve, and the vacuum pump 18. Temperature sensors are installed on both the surface of the heating element 23 and the bottom surface of the tank 1. These sensors monitor the temperature of the heating element 23 and the tank 1, ensuring they remain within a preset temperature range. Furthermore, a pressure sensor connected to the inside of the tank 1 is installed on the top cover 3. This pressure sensor monitors the pressure inside the tank 1. Both the pressure sensor and the temperature sensor are electrically connected to the controller. Because steam increases during evaporation, the controller automatically activates the vacuum pump 18 to release gas when pressure is lost, thus maintaining the set pressure in the tank 1.

[0030] Based on the above embodiments, further optimization is possible. At least one observation port 2 is provided on the upper side of the tank body 1, which facilitates observation of the internal condition of the tank body. Moreover, when the observation port 2 is removed, the internal condition of the tank body can be inspected and maintained.

[0031] Based on the above embodiments, further optimization can be achieved by providing an alarm on the control cabinet 11, and a control panel and operation buttons on its surface. The control panel, operation buttons, and alarm are electrically connected to the controller.

[0032] Based on the above embodiments, further optimizations can be made by providing a valve on the fourth conduit 9. When the liquid in the collection tank 7 is discharged, the valve is closed to prevent outside air from entering the collection tank 7 through the fourth conduit 9. After the liquid is drained, the discharge valve 17 can be closed. In addition, an ultrasonic liquid level sensor electrically connected to the controller is provided on the collection tank 7 to detect the liquid level in the collection tank 7.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
