Description

Technical Field

[0001] The utility model relates to the field of pharmaceutical machinery, and particularly relates to a device for conveniently adjusting the temperature of an ointment container. Background Art

[0002] Plaster is a kind of externally applied traditional Chinese medicine, anciently called thin paste, which is made by boiling vegetable oil or animal oil with medicine into a gelatinous substance and applying it on one side of cloth, paper or leather. It can be attached to the affected area for a long time, and the plaster plays a role through the skin. The plaster application therapy is one of the commonly used external treatment methods in traditional Chinese medicine clinical practice, which follows the principles of syndrome differentiation and treatment of traditional Chinese medicine and the efficacy, main treatment and meridian tropism of traditional Chinese medicine.

[0003] In the process of traditional plaster boiling and preparation, a plaster boiling device is needed. The plaster boiling device is an auxiliary device used in the production and processing of plasters to boil the active ingredients of the plasters and liquid preparations such as glycerol, and finally boil them into a gelatinous state for subsequent processing. In the process of using the plaster boiling device to process and produce plasters, it is necessary to first add the liquid preparation into the plaster boiling device. The liquid preparation includes glycerol and other liquid adjuvants, and is stirred and mixed evenly in the plaster boiling device at a temperature above 130 degrees Celsius, that is, the liquid preparation preparation is completed. After natural airing, the temperature of the liquid preparation is reduced by about 30 degrees Celsius, and then the medicine is added.

[0004] During the process of preparing plasters, since the preparation temperatures required for the liquid preparation and the medicine are different, it is first necessary to heat up the equipment to keep it at about 130 °C for liquid preparation, and then add the medicine after the temperature of the liquid preparation is reduced by about 30 °C through airing. However, the process of natural airing for temperature reduction is slow, and the long waiting time will affect the performance of the final plaster product. Therefore, it is usually necessary to cool down the liquid preparation by an external device after the liquid preparation is completed. There are mainly two existing cooling devices. One is to pass cold water or cold oil into the periphery of the device and cool down the device through heat exchange. This method has a relatively fast cooling speed. However, using the existing device to cool down the liquid preparation through an external oil tank often occupies a large area, and at the same time, the cooling function is single, and it is impossible to heat up the liquid preparation during the process of plaster boiling, which is not convenient to use. The other is to cool down the liquid preparation by a cooling and heating integrated machine. The cooling and heating integrated machine has a heating function and is more convenient to use. However, when the cooling and heating integrated machine heats up the liquid preparation, it is necessary to first heat up the cold oil in the oil tank through a heater, and then perform heat exchange between the heated hot oil and the liquid preparation in the plaster boiling device to increase the temperature of the liquid preparation. When the liquid preparation is ready, the cooling and heating integrated machine cools down the hot oil in the oil tank, and then performs heat exchange with the liquid preparation in the plaster boiling device to reduce the temperature of the liquid preparation by about 30 °C. At this time, the medicine is added. This process requires all the hot oil in the oil tank to be cooled down, and this cooling process lasts for a long time, about 2-3 hours. The long cooling time will affect the final efficacy of the plaster, and at the same time, the long cooling operation will also affect the work efficiency. Utility Model Content

A heater and a liquid storage barrel are provided on the heating and cooling circulation pipeline. The heater and the liquid storage barrel are connected in parallel, and a valve is provided between the heater and the liquid storage barrel. When the valve is closed, the heater starts to work to heat the liquid in the plaster container; when the valve is opened, the liquid storage barrel starts to work to cool the liquid in the plaster container.

[0008] Preferably, the heating and cooling circulation pipeline includes a spiral pipeline arranged in the first chamber and a first circulation pipeline and a second circulation pipeline connected to both ends of the spiral pipeline. The first circulation pipeline is connected to a three-way valve through the power device. The second end of the three-way valve is connected to a liquid storage barrel, and the third end of the three-way valve is connected to a heater. The other end of the heater is connected to the second circulation pipeline. A third circulation pipeline communicating with the liquid storage barrel is also connected to the second circulation pipeline, and a valve is provided on the third circulation pipeline.

[0009] Preferably, the heater includes a second chamber, and a partition is provided in the second chamber. The partition divides the second chamber into a second left chamber and a second right chamber, and one end of the second left chamber and the second right chamber communicates, while the other end is completely isolated. Heating pipes are provided in both the second left chamber and the second right chamber. The three-way valve is connected to the completely isolated end of the second left chamber and the second right chamber, and the second circulation pipeline is connected to the completely isolated end of the second right chamber and the second left chamber.

[0010] Preferably, a plurality of sensors are provided inside the first chamber, and the sensors monitor the temperature of the liquid in the ointment container in real time. During the process of cooling the liquid in the ointment container, when the temperature approaches the preset temperature, the electric actuator controls the three-way valve to repeatedly close and open. When the temperature further approaches the preset temperature, the electric actuator controls the three-way valve to connect to the heater to heat the liquid in the heating and cooling circulation pipeline, so as to prevent the temperature of the liquid in the ointment container from dropping below the preset temperature.

[0011] Preferably, a liquid discharge port is provided at the bottom of the liquid storage barrel, and the liquid discharge port is used to discharge waste liquid; the volume of the first chamber accounts for one-sixth to one-half of the volume of the liquid storage barrel.

[0012] Preferably, the volume of the first chamber accounts for one-fifth to one-fourth of the volume of the liquid storage barrel.

[0013] Preferably, a single spiral pipeline is provided inside the first chamber. One end of the single spiral pipeline is connected to the first circulation pipeline, and the other end of the single spiral pipeline is connected to the second circulation pipeline.

[0014] Preferably, a double spiral pipeline is provided inside the first chamber. One end of the double spiral pipeline is connected to the first circulation pipeline, and the other end of the double spiral pipeline is connected to the second circulation pipeline.

[0015] Preferably, a cold water circulation pipeline is also provided on the liquid storage barrel. The cold water circulation pipeline includes a cold water pipe wound around the periphery of the liquid storage barrel, and cold water flows into the cold water pipe and exchanges heat with the liquid in the liquid storage barrel and then is discharged.

[0016] Preferably, it further includes a housing. An installation plate is provided inside the housing. The installation plate supports the liquid storage barrel at the upper part of the housing. A power device, a heater and a three-way valve are provided below the installation plate. The power device, the heater and the three-way valve are arranged in sequence from left to right. The second end of the three-way valve passes through the installation plate and is connected to the liquid storage barrel. A first through hole is provided on the housing. The first circulation pipeline passes through the first through hole and is connected between the spiral pipeline and the power device. A second through hole is provided on the housing. The second circulation pipeline passes through the second through hole and is connected between the other end of the spiral pipeline and the heater.

[0017] In the above technical solution, by arranging the heater and the liquid storage barrel in parallel without interference, during the process of heating the ointment container, the valve is closed to make the heater join the temperature rising and falling circulation pipeline. The oil in the temperature rising and falling circulation pipeline is heated by the heater, and the heated oil in the temperature rising and falling circulation pipeline exchanges heat with the liquid in the ointment container, finally raising the temperature of the liquid in the ointment container to the required temperature. The method of continuously heating the oil in the temperature rising and falling circulation pipeline is used to provide heat source for the liquid in the ointment container, with fast heating speed and high safety. During the process of cooling the plaster container, the valve is opened to connect the liquid storage barrel to the temperature rising and falling circulation pipeline. During the cooling process, the method of cold oil replacement is used to cool the liquid inside the plaster container, that is, normal temperature oil is provided in the liquid storage barrel. The normal temperature oil in the liquid storage barrel flows into the spiral pipeline through the temperature rising and falling circulation pipeline to exchange heat with the liquid in the plaster container, raising the temperature of the normal temperature oil in the circulation pipeline and lowering the temperature of the liquid in the plaster container. And through the continuous circulation of the circulation pipeline, the liquid in the plaster container is continuously cooled until it reaches the preset temperature. During the cooling process, it is not necessary to first cool the high-temperature circulating oil, but to continuously introduce the normal temperature oil in the liquid storage barrel into the spiral pipeline to cool the liquid in the plaster container by the method of cold oil replacement, reducing energy consumption.

[0018] By setting a three-way valve, one end of the three-way valve is connected to the spiral pipeline through a power device, the second end of the three-way valve is connected to a liquid storage barrel, the third end of the three-way valve is connected to a heater, and the other end of the heater is connected to the other end of the spiral pipeline through a second circulation pipeline. A third circulation pipeline connected to the liquid storage barrel is provided on the second circulation pipeline, and a valve is provided on the third circulation pipeline. The parallel connection of the heater and the liquid storage barrel is realized by opening and closing the valve. When the electric actuator controls the three-way valve to conduct horizontally, that is, when the first end and the third end are conducted, the heater is connected to the circulation pipeline; when the electric actuator controls the first end and the second end of the three-way valve to conduct, the liquid storage barrel is connected to the circulation pipeline. By setting multiple sensors to monitor the temperature of the liquid in the ointment container in real time, when the temperature drops close to the preset temperature, the electric actuator controls the start and stop of the three-way valve to reduce the heat exchange speed between the liquid storage barrel and the ointment container, avoiding too fast a cooling speed. Further, when the temperature is closer to the preset temperature, the electric actuator controls the first end and the third end of the three-way valve to conduct, and adds the heater to the temperature rising and falling circulation pipeline to prevent the temperature from dropping too fast below the preset temperature.

Detailed Embodiment

[0022] The following further describes the present invention with reference to the drawings:

[0023] As Figures 1 to 2As shown in the figure, the device for conveniently adjusting the temperature of the plaster container includes an ointment container 1, a power device 3, a heater 4, and a liquid storage barrel 7. A first chamber 11 is provided along the side wall of the ointment container 1. The first chamber 11 is connected to a temperature-raising and -lowering circulation pipeline. A heater and a liquid storage barrel are arranged in parallel on the temperature-raising and -lowering circulation pipeline. The temperature-raising and -lowering circulation pipeline is used to control the temperature change of the ointment container 1. The temperature-raising and -lowering circulation pipeline further includes a spiral pipeline arranged in the first chamber 11 and a first circulation pipeline 2 and a second circulation pipeline 21 connected to both ends of the spiral pipeline. The first circulation pipeline 2 is connected to a three-way valve 5 through the power device 3. The second end of the three-way valve 5 is connected to the liquid storage barrel 7. The third end of the three-way valve 5 is connected to the heater 4. The other end of the heater 4 is connected to the other end of the spiral pipeline through the second circulation pipeline 21. A third circulation pipeline 6 communicating with the liquid storage barrel 7 is provided on the second circulation pipeline 21, and a valve 61 is provided on the third circulation pipeline 6. The functions of temperature raising and lowering are realized by the opening and closing of the valve 61 in cooperation with the three-way valve. When the electric actuator controls the first end and the third end of the three-way valve 5 to be conducted and the valve is closed, the heater 4 is connected to the circulation pipeline to heat the ointment container 1. When the electric actuator controls the first end and the second end of the three-way valve 5 to be conducted and the valve is opened, the liquid storage barrel 7 is connected to the circulation pipeline to cool the ointment container 1.

[0024] During the preparation process of the plaster, first, the temperature of the ointment container 1 needs to be raised to about 130 °C for liquid preparation and maintained around this temperature. After the liquid preparation is completed, the temperature needs to be quickly lowered to about 100 °C to add the prepared medicine. The heater 4 and the liquid storage barrel 7 are arranged in parallel without interfering with each other. Preferably, the liquid in the temperature-raising and -lowering circulation pipeline is oil at normal temperature, which is more convenient for temperature raising and lowering operations. During the process of heating the liquid preparation in the ointment container 1, the oil in the circulation pipeline is heated by the heater 4, and the heated oil in the circulation pipeline exchanges heat with the liquid preparation in the ointment container 1, finally raising the temperature of the liquid preparation in the ointment container 1. By continuously heating the oil in the temperature-raising and -lowering circulation pipeline, a heat source is provided for the liquid preparation in the ointment container 1, with a fast heating rate and high safety. During the cooling process, it is not necessary to first cool a large amount of high-temperature oil. Instead, the normal-temperature oil in the liquid storage barrel 7 flows into the spiral pipeline through the temperature-raising and -lowering circulation pipeline to exchange heat with the liquid preparation in the ointment container 1, raising the temperature of the normal-temperature oil in the circulation pipeline and lowering the temperature of the liquid preparation in the ointment container 1. And through the continuous circulation of the temperature-raising and -lowering circulation pipeline, the liquid preparation in the ointment container 1 is continuously cooled until it reaches the required temperature.

[0025] In this embodiment, the first chamber 11 occupies one-sixth to one-half of the volume of the liquid storage barrel 7. Preferably, the first chamber 11 occupies one-fifth to one-fourth of the volume of the liquid storage barrel 7, so that the oil in the liquid storage barrel 7 can reduce the temperature of the liquid in the ointment container 1 to the preset temperature through the first chamber 11, and at the same time, it will not cause too much oil in the liquid storage barrel 7 and occupy too much space. The heater 4 includes a second chamber, and a partition 41 is provided in the second chamber. The partition 41 divides the second chamber into a second left chamber 42 and a second right chamber 43. One end of the second left chamber 42 and the second right chamber 43 is connected, and the other end is completely isolated. Heating tubes 411 are provided in both the second left chamber 42 and the second right chamber 43. The three-way valve 5 is connected to the completely isolated end of the second left chamber 42 and the second right chamber 43, and the second circulation pipeline 21 is connected to the completely isolated end of the second right chamber 43 and the second left chamber 42, so that the heating tubes 411 can fully exchange heat with the oil flowing through the heater and then flow out of the heater. In this embodiment, it further includes a housing 8. An installation plate 81 is provided inside the housing 8. The installation plate 81 supports the liquid storage barrel 7 at the upper part of the housing 8. A power device 3, a heater 4 and a three-way valve 5 are provided below the installation plate 81. The power device 3, the heater 4 and the three-way valve 5 are arranged in sequence from left to right. The second end of the three-way valve 5 passes through the installation plate 81 and is connected to the liquid storage barrel 7. A first through hole (not shown in the figure) is provided on the housing 8. The first circulation pipeline 2 passes through the first through hole and is connected between the spiral pipeline and the power device. A second through hole (not shown in the figure) is also provided on the housing 8. The second circulation pipeline 21 passes through the second through hole and is connected between the other end of the spiral pipeline and the heater. And rollers are provided at the bottom of the housing 8, which is convenient for pushing the device for conveniently adjusting the temperature of the ointment container 1 to the position where it is needed.

[0026] In a preferred embodiment, a plurality of sensors are provided inside the first chamber 11 to monitor the temperature of the liquid in the ointment container 1 in real time by setting the plurality of sensors. When the temperature drops close to the preset temperature, the electric actuator controls the start and stop of the three-way valve 5 to reduce the heat exchange speed between the liquid storage barrel 7 and the ointment container 1, avoiding too fast a cooling speed. Further, when the temperature is closer to the preset temperature, the electric actuator controls the three-way valve 5 to add the heater 4 to the temperature rising and falling circulation pipeline to prevent the temperature from dropping too fast and being lower than the preset temperature.

[0027] In a preferred embodiment, a double spiral pipeline is provided inside the side wall of the first chamber 11. One end of the double spiral pipeline is connected to the first circulation pipeline 2, and the other end of the double spiral pipeline is connected to the second circulation pipeline 21; further increasing the heat exchange efficiency.

[0028] In a preferred embodiment, a liquid discharge port 71 is provided at the bottom of the liquid storage barrel 7, which is convenient for discharging or replacing the liquid in the liquid storage barrel 7.

[0029] In a preferred embodiment, a cold water circulation pipeline is further provided on the liquid storage barrel 7. The cold water circulation pipeline includes a cold water pipe wound around the periphery of the liquid storage barrel 7. Cold water flows into the cold water pipe and exchanges heat with the oil in the liquid storage barrel 7 and then is discharged, accelerating the cooling rate of the oil in the liquid storage barrel 7. After the oil exchanges heat with the liquid in the ointment container 1 and warms up, it exchanges heat with cold water for rapid cooling, which is more convenient for use. A cold water inlet 82 and a cold water outlet 83 are further provided on the outer shell. One end of the cold water pipe is connected to the cold water inlet 82, and the other end of the cold water pipe is connected to the cold water outlet 83.

[0030] During use, first, the electric actuator is used to control the first end and the third end of the three-way valve 5 to be conducted, and the valve 61 is closed, so that the temperature rise and fall circulation pipeline forms a closed loop in which the first circulation pipeline 2, the power device 3, the three-way valve 5, the heater 4, the second circulation pipeline 21, and the spiral pipeline are connected in sequence end to end. At this time, only the heater 4 heats the oil flowing through the temperature rise and fall circulation pipeline to realize the temperature rise of the liquid in the ointment container 1. When the temperature sensor detects that the temperature of the liquid in the ointment container 1 reaches the preset temperature, it is maintained at this temperature, and the liquid in the ointment container 1 is prepared for liquid. After the liquid preparation is completed, the valve 61 is opened, and the electric actuator is used to control the first end and the second end of the three-way valve 5 to be conducted, so that the temperature rise and fall circulation pipeline forms a closed loop in which the first circulation pipeline 2, the power device 3, the three-way valve 5, the liquid storage barrel 7, the second circulation pipeline 21, and the spiral pipeline are connected in sequence end to end. At this time, the normal temperature oil in the liquid storage barrel 7 exchanges heat with the liquid in the ointment container 1, so that the temperature of the liquid in the ointment container 1 decreases. During the cooling process, the temperature sensor monitors in real time. When the temperature of the liquid in the ointment container 1 drops to near the preset temperature, the electric actuator controls the start and stop of the three-way valve 5 to reduce the heat exchange speed between the liquid storage barrel 7 and the ointment container 1, avoiding too fast cooling speed. Further, when the temperature is closer to the preset temperature, the electric actuator controls the three-way valve 5 to add the heater 4 into the temperature rise and fall circulation pipeline to prevent the temperature from dropping too fast below the preset temperature.

[0031] This embodiment is only an illustration of the concept and implementation of the present invention, and does not limit it. Under the concept of the present invention, the technical solutions without substantial transformation are still within the protection scope.
