Description

Technical Field

[0002] Vertical pressure steam sterilizer is a kind of equipment that uses pressure saturated steam to sterilize items quickly and reliably. This sterilizer is suitable for many fields, including medical and health care, scientific research, agriculture and other units, and can sterilize medical equipment, dressings, glassware, solution culture medium, etc.

[0003] In order to process the steam discharged from the vertical pressure steam sterilizer and avoid the waste of water resources caused by steam escape, the existing vertical pressure steam sterilizer will be equipped with a processing device at the top outlet, such as a steam processing device for a vertical pressure steam sterilizer proposed in the patent with authorization announcement number CN214969412U. The application absorbs the steam into the absorption tube through the pump body, and due to the long length of the absorption tube, the steam will condense inside the absorption tube, thereby forming reflux water for collection.

[0004] However, the temperature of steam discharged from the vertical pressure steam sterilizer is relatively high. This high temperature will cause the temperature of the absorber tube to rise as a whole. When the temperature of the absorber tube rises, the condensation efficiency of the steam inside the absorber tube will be greatly reduced, thereby affecting the steam recovery and treatment effect.

[0017] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0018] like Figure 1 to Figure 2As shown, a steam treatment device of a vertical pressure steam sterilizer comprises a recovery cover 1, an absorption pipe 2, a suction pump 3 and a low temperature maintenance structure. The absorption pipe 2 is connected to the top of the recovery cover 1. The recovery cover 1 is the main recovery structure of steam. When in use, it can be covered at the outlet at the top of the vertical pressure steam sterilizer. The absorption pipe 2 is a structure for steam transportation and condensation. When the steam flows along the absorption pipe 2, it will condense inside the absorption pipe 2. The suction pump 3 is connected to the end of the absorption pipe 2 away from the recovery cover 1. The suction force generated by the suction pump 3 can ensure the flow of gas and complete the collection. The detailed working and principle of the recovery cover 1, the absorption pipe 2 and the suction pump 3 can refer to the comparative patent with the authorization announcement number CN214969412U. The present application is only a further improvement made based on the prior art. The low temperature maintenance structure is arranged on the surface of the absorption pipe 2, which can generate cold energy to cool the absorption pipe 2 to avoid the absorption pipe 2 from being affected by the heat of steam and causing an exaggerated temperature rise. The condensation efficiency can be ensured by using low temperature.

[0019] The low temperature maintenance structure includes a semiconductor refrigeration sheet 4 arranged on the surface of the absorption tube 2. The number of semiconductor refrigeration sheets 4 is three and they are evenly distributed on the surface of the absorption tube 2. The semiconductor refrigeration sheet 4 is the main refrigeration component. The semiconductor refrigeration sheet 4 is a heat pump made of semiconductor materials, also known as a thermoelectric refrigeration sheet. Its principle is based on the Peltier effect, that is, when direct current passes through an electric couple composed of two different semiconductor materials, heat can be absorbed and released at both ends of the electric couple respectively, thereby achieving the purpose of refrigeration. The work of the semiconductor refrigeration sheet 4 can be used to cool and cool the absorption tube 2 to avoid the absorption tube 2 from heating up too seriously and affecting the condensation effect. The cold end of the semiconductor refrigeration sheet 4 is close to the absorption tube 2, and the hot end of the semiconductor refrigeration sheet 4 is far away from the absorption tube 2. The hot end of the semiconductor refrigeration sheet 4 is fixedly connected with a profile heat dissipation sheet. Heater 5, profile radiator 5 is a radiator that uses profile as a heat dissipation element. Profile radiator 5 is usually made of metal materials such as aluminum alloy, copper or steel. Heat is transferred from the surface of the radiator to the air by heat conduction and convection. The design of profile radiator 5 usually adopts fins made of aluminum alloy or copper to increase the heat dissipation area and enhance the heat dissipation effect. In addition, parameters such as fin height, thickness, and spacing of profile radiator 5 will also affect its heat dissipation performance. Profile radiator 5 assists in the dissipation of the hot end temperature of semiconductor refrigeration plate 4, thereby improving the cooling efficiency of semiconductor refrigeration plate 4. A heat dissipation fan 6 is provided on the side of profile radiator 5 away from semiconductor refrigeration plate 4. When working, heat dissipation fan 6 can blow toward profile radiator 5, thereby increasing the air flow speed on the surface of profile radiator 5 and accelerating the heat dissipation rate.

[0020] like Figure 2As shown, three evenly distributed connection blocks 7 are fixedly connected to the surface of the absorption tube 2. The connection blocks 7 are made of highly efficient heat-conducting material. The semiconductor refrigeration plate 4 is fixedly connected to the surface of the connection blocks 7. The connection blocks 7 can be used as the bearing plane of the low-temperature maintenance structure, thereby completing the refrigeration work of the arc pipeline.

[0021] like Figure 2 As shown, a connecting rod 8 is fixedly connected to the surface of the heat dissipation fan 6, and the connecting rod 8 is fixedly connected to the connecting block 7. The connecting rod 8 can be used to effectively fix the heat dissipation fan 6 to one side of the profile radiator 5, thereby ensuring that the heat dissipation fan 6 is aligned with the profile radiator 5.

[0022] like Figure 2 As shown, there are four connecting rods 8 which are evenly distributed on the surface of the heat dissipation fan 6 . The four connecting rods 8 can support the heat dissipation fan 6 around the heat dissipation fan 6 , thereby ensuring the stability of the heat dissipation fan 6 .

[0023] like Figure 1 As shown, a collecting box 9 is fixedly connected to the bottom of the suction pump 3, and the outlet of the suction pump 3 is connected to the collecting box 9. The condensed water can pass through the suction pump 3 and be temporarily stored in the collecting box 9, so as to facilitate people's use.

[0024] like Figure 1 As shown, an observation groove 10 is provided on the surface of the collection box 9, and a transparent visual plate 11 is fixedly connected to the inside of the observation groove 10. The observation groove 10 can penetrate the transparent visual plate 11 to observe the water volume inside the collection box 9, so as to know whether it needs to be cleaned and discharged.

[0025] The working principle of the utility model is: when in use, the semiconductor refrigeration sheet 4 can generate cold energy, and then the cold energy is transmitted to the absorption tube 2 through the connecting block 7, thereby reducing the temperature of the absorption tube 2, and the low-temperature absorption tube 2 can ensure the efficiency of condensation. At the same time, the coordinated work of the profile radiator 5 and the heat dissipation fan 6 can effectively increase the divergence of the hot end temperature of the semiconductor refrigeration sheet 4, thereby increasing the refrigeration effect of the semiconductor refrigeration sheet 4.

[0026] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
