Description

Technical Field

[0001] The utility model relates to the field of pharmaceutical equipment, in particular to a device capable of automatically controlling the temperature of a medicine container. Background Art

[0002] Temperature control plays a crucial role in the pharmaceutical production process, for example during the mixing stage. Based on specific manufacturing process requirements, pharmaceuticals must undergo staged heating, insulation, and cooling during the mixing process to ensure their quality and efficacy. However, most current heating and cooling devices rely on manual intervention. This traditional control method makes it difficult to achieve precise temperature control during pharmaceutical production. Furthermore, this manual operation mode can lead to low production efficiency and unstable product quality, thereby affecting the overall manufacturing effect and market competitiveness of the pharmaceuticals. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the traditional control method in the prior art in the temperature control process of medicine production, which is difficult to achieve precise control and affects production efficiency and product quality, and to provide a device that can automatically control the temperature of medicine containers.

[0004] The utility model provides a device capable of automatically controlling the temperature of a medicine container, comprising:

[0005] a spiral tube, the spiral tube being located on the outer wall of a container for filling medicines;

[0006] a heating circuit, the heating circuit comprising a first storage tank, a first valve, and a second valve, the first storage tank being provided with a first storage tank inlet and a first storage tank outlet, the first storage tank inlet being in communication with the first valve, the first storage tank outlet being in communication with the second valve, the first valve being in communication with the outlet of the spiral tube, the second valve being in communication with the inlet of the spiral tube, and the first storage tank being used to store a heating liquid;

[0007] a cooling circuit, the cooling circuit comprising a second storage tank, a third valve, and a fourth valve, the second storage tank being provided with a second storage tank inlet and a second storage tank outlet, the second storage tank inlet being in communication with the third valve, the second storage tank outlet being in communication with the fourth valve, the third valve being in communication with the outlet of the spiral tube, and the fourth valve being in communication with the inlet of the spiral tube, the second storage tank being used to store a cooling liquid, the temperature of the heating liquid being higher than the temperature of the cooling liquid;

[0008] A controller is used to control the opening or closing of the first valve, the second valve, the third valve and the fourth valve.

[0009] The utility model provides a device that can automatically control the temperature of a medicine container. When the controller controls the first valve and the second valve to open and the third valve and the fourth valve to close, the heating liquid in the first storage tank can flow out through the first storage tank outlet and then enter the spiral tube. The heating liquid heats the container in the spiral tube. Then, the heating liquid flows out of the spiral tube and flows back into the first storage tank through the first storage tank inlet, forming the heating circuit.

[0010] The controller controls the third and fourth valves to open, while the first and second valves are closed, allowing coolant in the second tank to flow out through the second tank outlet and into the spiral tube, where the coolant cools the container. The coolant then flows out of the spiral tube and back into the second tank through the second tank inlet, forming a cooling circuit. The temperature of the heating liquid is higher than that of the cooling liquid, ensuring that the heating liquid heats the container while the cooling liquid cools it.

[0011] By controlling the heating circuit and the cooling circuit through the controller, accurate automatic control of different temperature stages in the drug production process can be achieved, thereby improving the efficiency and quality of drug production.

[0012] The spiral tube is a common part of the heating circuit and the cooling circuit. This solution allows the heating liquid in the spiral tube to be replaced by the cooling liquid, or the cooling liquid in the spiral tube to be replaced by the heating liquid when the heating stage and the cooling stage are switched between each other, thereby improving the conversion efficiency between the heating stage and the cooling stage.

[0013] The heating liquid and the cooling liquid are both heat-conducting liquids, such as silicone oil, ethylene glycol, purified water, etc. It should be noted that the temperature of the heating liquid is higher than the temperature of the cooling liquid.

[0014] Both the heating circuit and the cooling circuit may be provided with a device for driving liquid flow, and the device for driving liquid flow may be respectively arranged inside the first storage tank and the second storage tank, or may be respectively arranged on the pipelines of the heating circuit and the cooling circuit.

[0015] Preferably, a first pump is connected between the first tank outlet and the second valve, and a second pump is connected between the second tank outlet and the fourth valve. The first pump is used to drive the flow of heating liquid in the heating circuit, and the second pump is used to drive the flow of cooling liquid in the cooling circuit. The controller is also used to control the opening or closing of the first pump, thereby controlling the opening or closing of the heating circuit; the controller is also used to control the opening or closing of the second pump, thereby controlling the opening or closing of the cooling circuit.

[0016] Preferably, a heater is connected between the second valve and the first pump, and the controller is further configured to control the on / off switching of the heater. The heater is configured to heat the heating fluid in the heating circuit to a predetermined temperature. The heater may be a combustion heater utilizing a combustible material, or a resistance heater or electromagnetic heater utilizing electrical energy.

[0017] Preferably, the heater is a resistance heater or an electromagnetic heater.

[0018] Preferably, a cooler is connected between the fourth valve and the second pump, and the cooler is connected to the inlet of the second storage tank via a fifth valve. The controller is further configured to control the opening or closing of the fifth valve and the cooler. The cooler is configured to reduce the temperature of the coolant in the cooling circuit to a predetermined value, and the cooler may be a refrigerator or a cooling heat exchanger.

[0019] The controller controls the fifth valve to open, while the third valve and the fourth valve are closed, so that the coolant in the cooling circuit does not flow through the spiral tube, thereby ensuring that when the container is not cooled, the coolant in the second storage tank is always below the predetermined cooling temperature to ensure use in the next cooling stage.

[0020] Preferably, the cooler is a cooling heat exchanger having a medium outlet and a medium inlet. A cooling medium flows through the cooling heat exchanger, flowing into the cooling heat exchanger from the medium inlet and out of the cooling heat exchanger from the medium outlet. Heat is exchanged between the cooling medium and the coolant in the cooling circuit within the cooling heat exchanger, resulting in a lower temperature for the cooling medium. The cooling medium may be low-temperature air or tap water.

[0021] Preferably, a first temperature sensor is provided at the inlet of the spiral tube, and a second temperature sensor is provided at the outlet of the spiral tube. The first temperature sensor and the second temperature sensor are used to feed back the measured inlet temperature and outlet temperature of the spiral tube to the controller respectively.

[0022] During the heating phase, if the temperature measured by the second temperature sensor is lower than that measured by the first temperature sensor, it indicates that the container has not yet reached the predetermined temperature, and therefore, the heating circuit needs to be maintained to continue heating. When the temperature measured by the second temperature sensor is equal to the temperature measured by the first temperature sensor, it indicates that the container has reached the predetermined temperature, and therefore, the controller can stop the heating circuit to save energy and enter the heating and heat preservation phase. During the heating and heat preservation phase, if the temperature measured by the second temperature sensor or the temperature measured by the first temperature sensor is 2°C lower than the predetermined temperature, the controller restarts the heating circuit.

[0023] During the cooling phase, if the temperature measured by the second temperature sensor is higher than that measured by the first temperature sensor, it indicates that the container has not yet cooled to the predetermined temperature. Therefore, the cooling circuit needs to be maintained to continue cooling. When the temperature measured by the second temperature sensor is equal to the temperature measured by the first temperature sensor, it indicates that the container has cooled to the predetermined temperature. Therefore, the controller can stop the cooling circuit to save energy and enter the cooling and heat preservation phase. During the cooling and heat preservation phase, if the temperature measured by the second temperature sensor or the temperature measured by the first temperature sensor is 2°C higher than the predetermined temperature, the controller restarts the cooling circuit.

[0024] Preferably, the heating liquid and the cooling liquid are both silicone oil. Silicone oil has excellent thermal conductivity, good chemical stability and oxidation resistance, and can remain stable during high temperature and long-term use.

[0025] Preferably, the container, the heating circuit, and the cooling circuit are all provided with insulation layers. The heating circuit includes the following components: the pipelines within the heating circuit, the first storage tank, the first valve, and the second valve. The cooling circuit includes the following components: the pipelines within the cooling circuit, the second storage tank, the third valve, and the fourth valve.

[0026] The insulation layer can be made of a variety of materials, such as insulation cotton, polyurethane foam, etc., to reduce heat exchange between the device and the outside world.

[0027] Preferably, the temperature range provided by the heating liquid is 100°C-160°C, and the temperature range provided by the cooling liquid is 5°C-25°C.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The utility model provides a device that can automatically control the temperature of a drug container. By controlling the heating circuit and the cooling circuit by the controller, precise automatic control of different temperature stages in the drug production process can be achieved, thereby improving the efficiency and quality of drug production.
