Detailed Implementation

[0031] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0032] This application discloses a vertical pressure steam sterilizer.

[0033] like Figure 1 As shown, the vertical pressure steam sterilizer includes a housing 1. The top of the housing 1 is provided with an inlet 101 and a water inlet 102. The bottom center of the housing 1 is provided with a water outlet 103. The four corners of the bottom of the housing 1 are provided with casters 10. The inlet 101 is provided with an external thread 105 for threaded connection with the housing cover, and a first flange 104 for supporting the sterilization basket 5. The side of the water inlet 102 near the inside of the housing 1 is connected to a water inlet pipe 2, which is provided with a water inlet shut-off valve. The side of the water outlet 103 away from the inside of the housing 1 is connected to a water outlet pipe, which is provided with a water outlet shut-off valve. The heating mechanism includes an induction coil 3 and a heating element 4. The heating element 4 is located inside the housing 1 near the bottom center. The inner wall of the housing 1 near the bottom is provided with a thickened layer 106. The induction coil 3 is wound around the heating element 4 and is located inside the thickened layer 106. The housing 1 is provided with a power supply port connected to the induction coil 3.

[0034] The box 1 is provided with a material inlet 101 and a water inlet 102 on the top, which facilitates the introduction of materials and water source; the central water outlet 103 on the bottom ensures the effective discharge of condensed water after the sterilization process; the universal wheels 10 on the four corners of the bottom endow the box 1 with flexible mobility and convenient operability. The outer thread 105 at the material inlet 101 is designed to enable the box cover to be tightly connected with the box 1, and the design of the first flange 104 facilitates the stable placement of the sterilization basket 5. The water inlet valve and the water outlet valve respectively provided on the water inlet pipe 2 and the water outlet pipe effectively control the water supply and drainage process. The synergistic effect of the induction coil 3 and the heating element 4 in the heating mechanism significantly improves the heating efficiency, thereby shortening the sterilization cycle. The design of the thickened layer 106 not only enhances the structural stability of the box 1, but also protects the induction coil 3. The provision of the power supply port facilitates the connection of the power source, ensuring the stable operation of the induction coil 3.

[0035] Specifically, the box 1 is made of insulating material, the heating element 4 and the sterilization basket 5 are made of conductive metal, and the heating element 4 is connected with the box 1 through the heat insulation column 12.

[0036] The use of insulating material as the box 1 can avoid the heating effect of electromagnetic induction generated by the induction coil 3 on the box 1, thereby preventing scalding accidents when the operator accidentally touches it and improving the safety performance of the equipment. The use of conductive metal as the heating element enables the heating element 4 and the sterilization basket 5 to heat simultaneously, which can realize efficient heat generation and accelerate the sterilization process. The design of the heat insulation column 12 not only ensures the thermal insulation between the heating element 4 and the outer shell, further improving the safety factor of the system, but also provides stable support for the heating element 4, preventing damage to the element due to external vibration or impact.

[0037] As shown in Figure 1 and Figure 2 , the box cover includes a cover body 6, a guide frame 7 and a handle 8, the guide frame 7 is hingedly connected with the box 1, the guide frame 7 is provided with a through hole for the connecting rod of the handle 8 to pass through, the connecting rod penetrates through the through hole and is fixedly connected with the cover body 6, the cover body 6 is provided with an inner thread matched with the outer thread 105, and the cover body 6 is provided with a sealing ring 601 matched with the first flange 104.

[0038] The guide frame 7 is connected to the box 1 by a hinged manner, thereby ensuring the stability of the opening and closing process of the cover 6 and the convenience of the operation. The through hole allows the connecting rod of the handle 8 to pass through and is fixedly connected with the cover 6, thereby making the cover 6 and the handle 8 form a solid overall structure, and significantly improving the convenience of the operation. The internal thread on the cover 6 cooperates with the external thread 105 on the box 1, thereby ensuring the close connection between the cover 6 and the box 1. The sealing ring arranged at the cover 6 part is closely matched with the periphery of the sterilization basket 5 on the first flange 104, thereby significantly reducing the risk of steam leakage, improving the efficiency of the sterilization process, and ensuring the safety and reliability of the sterilization operation.

[0039] As shown in Figure 1 and Figure 2 , in order to reduce the safety hidden trouble caused by high pressure in the box 1, the cover 6 is provided with a pressure relief valve 602 at the top. The pressure relief valve 602 can effectively prevent the safety hidden trouble caused by the excessive pressure in the box 1 during the sterilization process, thereby ensuring the safety of the equipment operation. When the pressure in the box 1 exceeds the set value, the pressure relief valve 602 can be automatically opened to timely release the excessive pressure, thereby avoiding the damage of the equipment or safety accidents caused by the excessive pressure.

[0040] As shown in Figure 2 , the thickened layer 106 is provided with a water guide slope 107 inclined to the center of the box 1 at the top. The water guide slope 107 arranged at the top of the thickened layer 106 can effectively promote the condensate water to converge to the bottom of the box 1, thereby avoiding the accumulation of water above the thickened layer 106.

[0041] In addition, the second flange 108 for erecting the filter screen 11 is arranged at the bottom of the water guide slope 107. The arrangement of the second flange 108 is beneficial to the installation and dismounting of the filter screen 11, thereby ensuring that the impurities generated during the sterilization process can be effectively filtered, maintaining the cleanliness of the equipment, and facilitating the recovery of the condensate water.

[0042] In order to facilitate the acquisition of the internal information of the box 1, the pressure sensor and the temperature sensor are further arranged on the inner top wall of the box 1 (the pressure sensor and the temperature sensor are not shown in the figure). The pressure sensor and the temperature sensor have the ability to monitor the pressure and temperature in the box 1 in real time, thereby ensuring the safety and effect of the sterilization process. These sensors are arranged at the top of the box 1, which is helpful to reduce the measurement deviation caused by the condensation of steam, thereby improving the accuracy of the measurement.

[0043] As shown in Figure 1As shown, in order to more conveniently obtain the data detected by the pressure sensor and the temperature sensor, a control panel 9 is arranged on the outer wall of the box 1, and the control panel 9 is signal connected with the pressure sensor, the temperature sensor, the water inlet shutoff valve and the water outlet shutoff valve. The control panel 9 arranged on the outer wall of the box 1 can monitor and display the pressure and temperature data in the box 1 in real time, and through the signal connection with the pressure sensor and the temperature sensor, the sterilization process can be accurately monitored. In addition, the control panel 9 is signal connected with the water inlet shutoff valve and the water outlet shutoff valve, so that the operator can adjust the water inlet and outlet amount when needed, and ensure the safety and stability of the sterilization process.

[0044] The implementation principle of the vertical pressure steam sterilizer according to an embodiment of the present application is as follows: the filter screen 11 is placed at the second flange 108 through the material inlet 101, the sterilization basket 5 is placed at the first flange 104 through the material inlet 101, the material is put into the sterilizer through the material inlet 101, and then the water inlet shutoff valve is opened, and an appropriate amount of water is added through the water inlet 102. Then, the heating mechanism at the bottom of the box 1 starts to work, and the water inlet shutoff valve and the box cover are closed, the inductive coil 3 and the heating element 4 work together to rapidly increase the temperature in the box 1, and the steam generated after heating can increase the pressure in the box 1. During the heating process, the design of the thickened layer 106 enhances the structural stability and protects the inductive coil 3. The high-pressure steam in the box 1 sterilizes the material. After sterilization is completed, the box cover and the water outlet shutoff valve are opened, and the condensed water is discharged through the water outlet 103. The pressure relief valve 602 at the top of the box 1 ensures the safety during the sterilization process. During the whole process, the pressure sensor and the temperature sensor monitor the pressure and temperature in the box 1 in real time, the control panel 9 displays the data and allows the operator to adjust the water inlet and outlet amount.

[0045] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
