Description

Technical Field

[0001] The present invention belongs to the technical field of sterilizers, and in particular relates to a high-efficiency double-kettle sterilizer for contact lenses. Background Art

[0002] Contact lenses, also called corneal contact lenses, are lenses worn on the cornea of ​​the eyeball to correct vision or protect the eyes. According to the hardness of the material, they include hard, semi-hard, and soft. Contact lenses not only bring great improvements to patients with refractive errors such as myopia, hyperopia, and astigmatism in terms of appearance and convenience. They also have a wide field of vision and realistic vision. In addition, they also play a special role in controlling the development of myopia and astigmatism in adolescents and treating special eye diseases.

[0003] Since contact lenses belong to the category of medical devices, in existing industrial production, it is necessary not only to ensure dust-free sterilization in the production plant, but also to sterilize the single contact lens and the PP cup used to support it at high temperature before final packaging and shipment. Therefore, large-volume autoclave sterilizers must be used in the contact lens production plant to sterilize a large number of products at one time.

[0004] However, since the production of contact lenses belongs to the form of large-scale production, the amount of sterilization in each batch is also very large, so a large sterilization kettle is needed for sterilization. However, since the internal cavity of the large sterilization kettle is too large, the internal heating time takes a long time, which greatly increases the sterilization time, and each time the cavity is reopened to put in the next batch, it needs to be heated again. Such repeated heating and cooling also causes a huge waste of energy. Moreover, the sterilization temperature required for contact lenses is also very harsh. If it is too high, it will affect the shape of the lens after shaping, and if it is too low, it will not have a sufficient sterilization effect. Utility Model Content

[0005] In order to solve the above problems, this paper proposes a high-efficiency double-kettle sterilizer for contact lenses. The double-kettle sterilizer is stacked up and down and is equipped with a sterilizing kettle and a constant temperature kettle. The bottom of the double-kettle sterilizer is provided with a bottom frame. The top of the sterilizing kettle is connected to the top of the constant temperature kettle through a high-temperature pipe, and the bottom of the sterilizing kettle is connected to the top of the sterilizing kettle and the bottom of the constant temperature kettle through a return pipe. A drainage pump and a return pump are provided on the outside of the bottom of the sterilizing kettle. The bottom of the return pipe is provided with a return pump in series, and an overflow pipe is externally connected to the outside of the return pipe. A drainage pump is independently connected to the bottom of the return pipe. The return water pump is directly connected to the bottom of the sterilization kettle through the return water pipe, and the overflow pipe is directly connected to the bottom of the constant temperature kettle and the bottom of the sterilization kettle. The sterilization kettle and the constant temperature kettle in the form of a double kettle are used to preheat the sterilization temperature required for the contact lenses through the constant temperature kettle first, thereby ensuring that the contact lenses are kept stable and constant when placed in the sterilization kettle, which will not affect the quality of the lenses and can also improve the sterilization efficiency. The design of the return water pipe can also return the cooled high-temperature water to the constant temperature kettle for reheating, thereby reducing the amount of water used and reducing the electricity required for heating in the constant temperature kettle.

[0006] The sterilizing kettle and the constant temperature kettle have the same shape, both of which are horizontal cylinders. A bottom frame is provided at the bottom of the sterilizing kettle. The front and rear sides of the top of the sterilizing kettle are connected to the constant temperature kettle through stacked brackets. The sterilizing kettle is provided on one side of the top surface of the bottom frame, and a drainage pump and a return water pump are provided on the other side of the top surface of the bottom frame. The stacked double-kettle structure can minimize the overall volume of the sterilizer and facilitate the connection of the outer pipes of the two kettles.

[0007] A temperature inlet and a water return port are provided on the top of the sterilizing kettle, a water outlet is provided at the bottom of the sterilizing kettle, the bottom of the sterilizing kettle is connected to the bottom frame through a bracket, the temperature inlet is connected to the constant temperature kettle through a high-temperature pipe, the water return port is connected to the return water pump through a return water pipe, and the water outlet is connected to the return water pump through a return water pipe. The water that has been lowered and sunk can be conveniently discharged directly from the water outlet through the water outlet at the bottom of the sterilizing kettle, so that the return water pipe can reuse the water with temperature, and the water return port can directly return the water with sufficient temperature to the sterilizing kettle for spraying, so as to achieve reuse for sterilization, and the temperature inlet sprays the high-temperature water inside the constant temperature kettle evenly from top to bottom to ensure the sterilization effect.

[0008] A temperature outlet is provided at the top of the thermostatic kettle, a water return outlet is provided at the bottom of the thermostatic kettle, and a water supply pipe is provided at the rear end of the thermostatic kettle. The temperature outlet is connected to the sterilizing kettle through a high-temperature pipe, and the water return outlet is connected to a water return pump through a water return pipe. The water return outlet is connected to the bottom of the sterilizing kettle through an overflow pipe. The heated high-temperature water is discharged from the top through the thermostatic kettle, and the low-temperature return water enters from the bottom for reheating, while the water supply pipe continuously replenishes the loss.

[0009] The return water pipe is a parallel water pipe, and a return water pump is provided in the middle part of the return water pipe. The inlet and outlet of the return water pump are interconnected through the return water pipe, and the outlet of the return water pump is connected to the return water port and the return water port in a two-part manner. Butterfly valves are provided on the outer side of the outlet, the outer side of the return water port and the outer side of the return water port on the return water pipe. An overflow pipe is provided between the inner side of the butterfly valve of the return water port and the inner side of the butterfly valve of the outlet. A butterfly valve is provided in the middle part of the overflow pipe. A thermostat is provided on the outer side of the return water pump. The low-temperature water in the sterilizing kettle is transferred to the corresponding kettle through the return water pump in a parallel form according to the temperature reached by the return water pump. The overflow pipe can directly discharge the water inside the constant temperature kettle through the return water pump and the drainage pump when the double kettle sterilizer stops working, which is convenient for later maintenance.

[0010] A butterfly valve is provided in the middle of the high-temperature tube, and a temperature controller and a pressure relief valve are provided on the outside of the high-temperature tube. The sterilizing water inside the constant temperature kettle is tested through the temperature controller and the pressure relief valve to ensure the stability of the water and the pressure, thereby ensuring the safety of the entire device.

[0011] Beneficial effects:

[0012] A double-pot sterilizer and a constant temperature pot are used so that the constant temperature pot is used to preheat the contact lenses to the sterilization temperature required, thereby ensuring that the temperature remains constant when placed inside the sterilizer. This will not affect the quality of the lenses and can also improve the sterilization efficiency. The return pipe design can also return the cooled high-temperature water to the constant temperature pot for reheating, thereby reducing the amount of water used and the electricity required for heating in the constant temperature pot.

[0013] The stacked double kettle structure can minimize the overall volume of the sterilizer and facilitate the connection of the outer pipes of the two kettles.

[0014] The water that has been cooled and sunk can be easily discharged directly from the water outlet at the bottom of the sterilizer, so that the return pipe can reuse the water with temperature. The return water outlet can directly return the water with sufficient temperature to the sterilizer for spraying, so that it can be reused for sterilization. The temperature inlet sprays the high-temperature water inside the constant temperature kettle evenly from top to bottom to ensure the sterilization effect.

[0015] The heated high-temperature water is discharged from the top through a constant temperature kettle, and the low-temperature return water enters from the bottom for reheating, while the water supply pipe continuously replenishes the loss.

[0016] In parallel, the return water pump will transfer the low-temperature water in the sterilizer to the corresponding kettle according to the temperature measured by the return water pump. The overflow pipe can directly discharge the water inside the constant temperature kettle through the return water pump and the drain pump when the double kettle sterilizer stops working, which is convenient for later maintenance.

[0017] The sterilizing water inside the thermostatic kettle is tested through the temperature controller and the pressure relief valve to ensure the stability of the water and the pressure, thereby ensuring the safety of the entire device. BRIEF DESCRIPTION OF THE DRAWINGS
