[0037] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Combine the following Figures 1 to 3 , the coolant circulation sterilization device and the pill machine provided by the embodiment of the utility model are described in detail through specific embodiments and their application scenarios.

[0039] First, as Figure 1 As shown, this embodiment provides a coolant circulation sterilization device 1, including: a collection component 11, a heating and sterilization component 12 and a cooling component 13.

[0040] The collecting component 11 , the heating and sterilizing component 12 and the cooling component 13 are arranged in sequence along the flow direction of the cooling liquid, and together with the pill machine body 2 form a cooling liquid circulation loop.

[0041] The collecting component 11 is used to contain the cooling liquid, the heating and sterilizing component 12 is used to heat and sterilize the cooling liquid, and the cooling component 13 is used to cool the heated cooling liquid.

[0042] It can be understood that the coolant flowing out of the pill machine of this embodiment flows into the collecting component 11, and the collecting component 11 is used to buffer the coolant. As a buffer device for the coolant, the collecting component 11 stores the coolant involved in the pill making process of the pill machine. Because bacteria may be generated in the coolant during the pill making process, the bacteria need to be killed.

[0043] Specifically, the collecting component 11 may be a collecting tank having a trough-like structure with an open top.

[0044] The heating and sterilizing component 12 heats the cooling liquid introduced therein to increase the temperature of the cooling liquid so as to kill bacteria in the cooling liquid.

[0045] The cooling assembly 13 is used to cool down the sterilized cooling liquid so that the temperature of the cooling liquid reaches the requirement of the dripping pill process.

[0046] Specifically, the cooling component 13 may be a heat exchanger or a semiconductor refrigeration sheet.

[0047] The cooling liquid circulation sterilization device 1 provided by the utility model sequentially arranges a collecting component 11, a heating and sterilizing component 12 and a cooling component 13, and the pill machine body 2, the collecting component 11, the heating and sterilizing component 12 and the cooling component 13 constitute a cooling liquid circulation loop, so that the cooling liquid flows out from the pill machine body 2 in the cooling liquid circulation loop, is first buffered in the collecting component 11, then flows into the heating and sterilizing component 12 to kill bacteria after being heated, and then flows into the cooling component 13 to reduce the temperature of the sterilized cooling liquid to a temperature that meets the needs of the pills, and finally the cooling liquid flows into the pill machine, so that the cooling liquid is fully sterilized online. Compared with the increase in the temperature of the cooling liquid caused by ultraviolet sterilization, the cooling liquid circulation sterilization device 1 of this embodiment can reduce the temperature of the cooling liquid through the cooling component 13 after heating and sterilizing the cooling liquid, so that the temperature of the cooling liquid flowing into the pill machine body 2 meets the needs of the pills, thereby effectively controlling the temperature of the cooling liquid, ensuring the pill dropping effect of the pill machine, and being beneficial to improving the quality of the pills.

[0048] In some embodiments, Figure 1 As shown, the heating and sterilization assembly 12 of this embodiment includes a sterilization tank 121 and a heating element 122 .

[0049] The collecting component 11 is connected to the cooling component 13 through the sterilizing tank 121 , and the heating element 122 is disposed in the sterilizing tank 121 .

[0050] It is understandable that the sterilization tank 121 is a cylindrical closed structure that isolates the external air and bacteria in the surrounding environment. When the temperature inside the sterilization tank 121 rises, the closed structure prevents the high-temperature coolant from exchanging heat with the surrounding environment, thereby ensuring a good heating effect inside the sterilization tank 121.

[0051] Furthermore, the inlet end of the sterilization tank 121 is connected to the collecting component 11 , and the outlet end is connected to the cooling component 13 . The heating element 122 is installed in the sterilization tank 121 , and the cooling liquid is heated by the heating element 122 .

[0052] In some embodiments, Figure 1 As shown, the heating element 122 of this embodiment is an electric heating wire or an electric heating coil.

[0053] It is understandable that the electric heating wire or electric heating coil has a simple structure, high heating efficiency, and is easy to install and maintain. The electric heating wire or electric heating coil is installed in the sterilization tank 121 to directly heat the coolant in the sterilization tank 121. It has high heat transfer efficiency and a better heating effect on the coolant.

[0054] In some embodiments, Figure 1 and Figure 3 As shown, the coolant circulation sterilization device 1 of this embodiment further includes: a temperature sensor 14 and a controller 15 .

[0055] The temperature sensor 14 is used to collect the temperature of the coolant in the collection component 11. The temperature sensor 14 is connected to the controller 15, and the controller 15 is connected to the cooling component 13 and the heating and sterilization component 12 respectively.

[0056] The controller 15 is used to control the working states of the heating and sterilizing component 12 and the cooling component 13 according to the temperature information detected by the temperature sensor 14 .

[0057] It is understandable that, for the cooling liquid introduced from the collecting component 11, the heating and sterilizing component 12 heats the cooling liquid so that the cooling liquid is heated to a preset temperature, and the cooling liquid can meet the requirements of the dripping pill process at the preset temperature. In this embodiment, the temperature sensor 14 is used to detect the temperature of the cooling liquid in the collecting component 11, and the temperature information is fed back to the controller 15. When the temperature of the cooling liquid reaches the preset value, the controller 15 controls the heating and sterilizing component 12 to stop heating. When the temperature of the cooling liquid does not reach the preset value, the controller 15 controls the heating and sterilizing component 12 to start heating.

[0058] Optionally, the controller 15 may be a single chip microcomputer or a PLC controller. The temperature sensor 14 may be a thermal resistor.

[0059] In this embodiment, a temperature sensor 14 and a controller 15 are provided. The temperature sensor 14 detects the temperature of the coolant in the collection component 11. The controller 15 controls the start and stop of the heating and sterilization component 12 according to the comparison between the coolant temperature and the preset temperature, thereby realizing automatic control of the coolant temperature and ensuring the reliability of the coolant temperature in the coolant circulation sterilization device 1.

[0060] In some embodiments, Figure 1 and Figure 3 As shown, the coolant circulation sterilization device 1 of this embodiment further includes a pumping device 16 , a flow meter 17 and a controller 15 .

[0061] The pumping device 16 and the flow meter 17 are arranged on the coolant circulation loop. The flow meter 17 is connected to the controller 15 , and the controller 15 is connected to the pumping device 16 .

[0062] The controller 15 is used to control the working state of the pumping device 16 according to the flow information detected by the flow meter 17 .

[0063] It is understandable that the flow rate in the coolant pipeline needs to be maintained within a certain range. When the flow rate of the coolant pipeline is too large, the flow speed of the coolant is too fast, and the flow time of the coolant in the heating and sterilization component 12 and the cooling component 13 is too short, affecting the sterilization and cooling effects. When the flow rate of the coolant pipeline is too small, the flow speed of the coolant is too slow, and the flow time of the coolant in the heating and sterilization component 12 and the cooling component 13 is too long, affecting the circulation efficiency of the entire coolant pipeline, making the volume of coolant sterilized and cooled per unit time too small.

[0064] The pumping device 16 increases the energy of the coolant under the driving force, and makes the coolant circulate in the coolant circulation loop, wherein the pumping device 16 can be driven by electricity, hydraulics, or compressed air.

[0065] The flow meter 17 is used to detect the flow information on the coolant pipeline and feed the flow information back to the controller 15. When the flow information is higher than the preset value, the controller 15 controls the pumping device 16 to reduce the speed to reduce the coolant delivery flow rate. When the flow information is lower than the preset value, the controller 15 controls the pumping device 16 to increase the speed to increase the coolant delivery flow rate.

[0066] Specifically, the flow meter 17 may be a mass flow meter or a positive displacement flow meter.

[0067] In this embodiment, by setting up a pumping device 16 and a flow meter 17, the flow information of the coolant pipeline can be detected by the flow meter 17, and the working state of the pumping device 16 can be controlled according to the flow information to adjust the flow of the coolant pipeline, so that the flow of the coolant pipeline can be automatically adjusted, thereby improving the degree of automation of the coolant circulation sterilization device 1.

[0068] In some embodiments, Figure 1 As shown, the cooling assembly 13 of this embodiment includes a cooling coil and a heat pipe.

[0069] The cooling coil is coiled around the peripheral wall of the heat-conducting pipe, the heating and sterilizing component is connected with the pill machine body through the heat-conducting pipe, and a cooling medium is introduced into the cooling coil.

[0070] It can be understood that the cooling coil of this embodiment is arranged on the heat conduction pipe in a winding manner, one end of the heat conduction pipe is connected to the heating and sterilization component, and the other end is connected to the pill machine body. The cooling medium in the cooling coil exchanges heat with the coolant in the heat conduction pipe to reduce the temperature of the coolant. The cooling coil is coiled on the heat conduction pipe, has a compact structure, and has high heat exchange efficiency, and has a good cooling effect on the coolant.

[0071] Specifically, fins may be provided on the outside of the cooling coil to increase the surface area for heat exchange and improve the effect of heat exchange.

[0072] In some embodiments, Figure 1 As shown, the cooling coil in this embodiment is a plastic coil.

[0073] It is understandable that the plastic coil is made of high-quality engineering plastics, which is resistant to high temperature and corrosion, and is non-conductive. The plastic coil is coiled on the coolant pipeline, is light in weight, and has a small volume after installation, and does not occupy too much installation space, which is conducive to reducing the installation volume of the cooling component 13 and achieving a better cooling effect of the cooling component 13.

[0074] In some embodiments, Figure 1 As shown, the collection component of this embodiment includes a collection pool and an ultraviolet lamp.

[0075] The pill machine body is connected to the heating and sterilization component through the collecting pool. The ultraviolet lamp is arranged on the upper side of the collecting pool, and the ultraviolet lamp is used to sterilize the coolant.

[0076] It is understandable that the ultraviolet lamp 18 is used to emit ultraviolet light to the collection pool, and the ultraviolet light is used to irradiate the coolant to achieve the sterilization effect on the coolant. The ultraviolet lamp 18 is set on the upper side of the collection pool, and the coolant flowing into the collection pool from the pill machine body 2 is first sterilized. Even if the temperature of the coolant is increased during the sterilization process, the coolant needs to be heated up after entering the heating and sterilization component 12, and the temperature of the coolant is not uncontrollable. The cooling component 13 after the heating and sterilization component 12 can cool the coolant. In addition, since the coolant undergoes two rounds of sterilization in the collection pool and the heating and sterilization component 12, the degree of sterilization of bacteria is higher and wider, which further ensures the sterilization effect of the coolant.

[0077] Second, as Figure 2 As shown, this embodiment provides a coolant circulation sterilization device 1, including: a collection component 11, a heating and sterilization component 12 and a cooling component 13.

[0078] The collecting component 11, the heating and sterilizing component 12 and the cooling component 13 are connected in sequence along the flow direction of the coolant to form a first coolant circulation loop; the collecting component 11 is used to be connected with the pill machine body 2 to form a second coolant circulation loop.

[0079] The collecting component 11 is used to contain the cooling liquid, the heating and sterilizing component 12 is used to heat and sterilize the cooling liquid, and the cooling component 13 is used to cool the heated cooling liquid.

[0080] It can be understood that in the first cooling liquid circulation loop formed by the collecting component 11, the heating and sterilizing component 12 and the cooling component 13, the cooling liquid buffered in the collecting pool flows into the heating and sterilizing component 12, is heated in the heating and sterilizing component 12, and the bacteria in the heated cooling liquid are killed. Then, the high-temperature cooling liquid flows from the heating and sterilizing component 12 into the cooling component 13, where the temperature drops to the temperature required for the pellet process and flows back to the collecting pool.

[0081] In the second cooling liquid circulation loop, the cooling liquid circulates in the pill dropping machine body 2 and the collecting pool. The cooling liquid flowing out of the pill dropping machine body 2 enters the collecting pool and is then sent to the first cooling liquid circulation loop for sterilization. In the first cooling liquid circulation loop, the temperature of the cooling liquid is cooled to the temperature required for the pill dropping process. The cooling liquid that has been sterilized and has a temperature that meets the requirements flows into the pill dropping machine body 2 to carry out the pill dropping process.

[0082] The coolant circulation sterilization device 1 provided by the utility model circulates the coolant in the collection component 11, the heating and sterilization component 12 and the cooling component 13 through the first coolant circulation loop, so that the coolant in the collection component 11 is heated and sterilized and the temperature is reduced to a suitable temperature, and then sent back to the collection component 11 to ensure that the coolant in the collection component 11 always meets the sterilization and temperature requirements. At the same time, the coolant is circulated in the collection component 11 and the pill machine body 2 through the second coolant circulation loop, so that the coolant that meets the sterilization and temperature requirements can always flow into the pill machine body 2, and the coolant that has passed the pill process can flow into the collection component 11 to wait for the sterilization and temperature adjustment treatment of the coolant. The first coolant circulation loop and the second coolant circulation loop can control the flow rate and flow velocity respectively, so that the sterilization treatment of the coolant and the treatment of the coolant pill process can be separately controlled and adjusted, thereby increasing the flexibility of adjustment of the coolant circulation sterilization device 1.

[0083] Thirdly, Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a pill machine, including: a pill machine body 2 and a coolant circulation sterilization device 1, and the pill machine body is connected in series to a collecting component and a cooling component of the coolant circulation sterilization device.

[0084] Alternatively, the pill dropping machine comprises a pill dropping machine body and a cooling liquid circulation sterilization device, and the pill dropping machine body and the collecting components of the cooling liquid circulation sterilization device are connected in parallel.

[0085] The pill machine body 2 is connected to the coolant circulation sterilization device 1, and the coolant circulation sterilization device 1 is used to sterilize the coolant flowing out of the pill machine.

[0086] It can be understood that the pill machine body 2 is used to produce pills, and the coolant circulation sterilization device 1 is used to sterilize the coolant discharged from the pill machine body 2, and send the sterilized coolant whose temperature is adjusted to a preset value into the pill machine body 2 to realize the circulation sterilization treatment of the coolant, so that the coolant can be reused, the frequency of use of the coolant is increased, the coolant is saved, and the effect of economical production is achieved.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
