Description

Technical Field

[0001] This utility model relates to the field of disinfection and sterilization equipment, and in particular to a hydroxyl disinfection and sterilization equipment. Background Technology

[0002] Hydroxyl radical disinfection equipment is a device that utilizes hydroxyl free radicals for highly efficient disinfection and sterilization. Widely used in water treatment systems for stadium swimming pools, it generates highly oxidizing hydroxyl free radicals through advanced oxidation technology or specific catalytic reactions. These free radicals rapidly decompose organic pollutants, bacteria, viruses, and other harmful microorganisms in the water, while avoiding the residue problems of traditional chemical agents. This equipment not only improves the safety and purity of the water, but also ensures that the hydroxyl free radicals, at low concentrations, are non-irritating to the human body, producing no odor or causing discomfort to the skin or eyes. It also reduces potential harm to human health and the environment, making it an environmentally friendly and efficient solution in the modern swimming pool water treatment field.

[0003] Hydroxyl disinfection and sterilization equipment used in sports swimming pools generally uses ultraviolet light to irradiate a catalyst to carry out a photocatalytic reaction, thereby accelerating the generation rate of hydroxyl groups in the pool water. However, in existing hydroxyl disinfection and sterilization equipment, the catalyst is usually placed directly inside the equipment. During the disinfection process, hydroxyl groups are mainly distributed around the catalyst, resulting in an uneven distribution of hydroxyl groups between the upper and lower layers of pool water. The high concentration of hydroxyl groups in the lower layer leads to a slower photocatalytic reaction rate, causing a decrease in the hydroxyl generation rate. Meanwhile, the low concentration of hydroxyl groups in the upper layer of pool water results in a poor disinfection and sterilization effect.

[0004] Therefore, it is necessary to provide a new hydroxyl disinfection and sterilization device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a hydroxyl disinfection and sterilization device.

[0006] The hydroxyl disinfection and sterilization device provided by this utility model includes: an outer shell, a sealing cover detachably connected to the top of the outer shell, multiple ultraviolet lamps inserted inside the sealing cover, a positioning shell detachably connected to the bottom of the sealing cover, a storage plate for storing catalyst detachably connected to the bottom of the positioning shell, a stirring assembly rotatably connected to the top of the storage plate, the other end of the stirring assembly rotatably connected to the lower end face of the sealing cover, and a water inlet pipe and a water outlet pipe provided on the side wall of the outer shell, the water outlet pipe being located above the water inlet pipe and the water inlet pipe being directly opposite the stirring assembly.

[0007] Preferably, the stirring assembly includes a stirring column, one end of which is rotatably connected to the lower end face of the sealing cover, and the other end of which is rotatably connected to the top wall of the positioning shell. A stirring block is inserted through the bottom end of the stirring column, and the bottom end of the stirring block is rotatably connected to the upper end face of the storage plate. A connecting rod is integrally connected to the top end of the stirring block, and the connecting rod is inserted into the stirring column.

[0008] Preferably, the upper end face of the positioning shell is rotatably connected to a plurality of rotating rods, the other end of which is threaded to a sealing cover, and the top wall of the positioning shell is provided with a circular through hole for the connecting rod to pass through.

[0009] Preferably, the stirring block is frustum-shaped, and multiple baffles are integrally connected to the side wall of the stirring block.

[0012] Compared with related technologies, the hydroxyl disinfection and sterilization equipment provided by this utility model has the following beneficial effects:

[0013] This invention provides a hydroxyl disinfection and sterilization device. In specific implementation, pool water impacts the surface of the stirring component through the inlet pipe, causing the stirring component to rotate. Under the action of the stirring component, the hydroxyl groups in the pool water are evenly dispersed in the pool water, thereby reducing the concentration of hydroxyl groups near the catalyst and avoiding a decrease in the forward reaction rate of the photocatalytic reaction between ultraviolet light and the catalyst due to excessively high hydroxyl concentration. At the same time, the stirring component can frequently exchange the upper and lower pool water, making the hydroxyl distribution more uniform. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please refer to the following: Figure 1 — Figure 3 ,in, Figure 1 A schematic diagram of the overall structure of the hydroxyl disinfection and sterilization device provided by this utility model; Figure 2 A cross-sectional structural schematic diagram of the hydroxyl disinfection and sterilization device provided by this utility model; Figure 3 A schematic diagram of the stirring assembly of the hydroxyl disinfection and sterilization device provided by this utility model.

[0020] In specific implementation, a hydroxyl-based disinfection and sterilization device has the following structure: Figure 1 — Figure 3 As shown, it includes: an outer shell 1, a sealing cap 2 threadedly connected to the top of the outer shell 1, multiple ultraviolet lamps 3 inserted inside the sealing cap 2, a positioning shell 4 connected to the bottom of the sealing cap 2 via a rotating rod 5, multiple rotating rods 5 being bolted to the lower end face of the sealing cap 2, the other end of multiple rotating rods 5 being bolted to the upper end face of the positioning shell 4, a storage plate 6 for storing catalyst threadedly connected to the bottom of the positioning shell 4, a stirring assembly 7 rotatably connected to the top of the storage plate 6, the other end of the stirring assembly 7 rotatably connected to the lower end face of the sealing cap 2, and a water inlet pipe 8 and a water outlet pipe 9 provided on the side wall of the outer shell 1, the water outlet pipe 9 being located above the water inlet pipe 8, and the water inlet pipe 8 being directly opposite the stirring assembly 7;

[0021] It should be noted that the water inlet pipe 8 has a "thin-thick" structure. The diameter of the end of the water inlet pipe 8 that is inserted into the outer shell 1 is thinner. According to Bernoulli's principle, when the pool water enters the outer shell 1 through the water inlet pipe 8, the water flow rate increases because the diameter of the water inlet pipe 8 changes from large to small. This causes the pool water to impact the stirring component 7, thereby driving the stirring component 7 to rotate.

[0022] The cavity between the storage plate 6 and the positioning shell 4 is used to store the catalyst. The catalyst can be titanium dioxide. The titanium dioxide is irradiated by ultraviolet lamp 3 to accelerate the generation rate of hydroxyl groups in the water. When the pool water drives the stirring component 7 to rotate, the stirring component 7 drives the catalyst to rotate, so that the catalyst is suspended in the water, so that the catalyst is fully in contact with the water and the photocatalytic reaction rate is maximized.

[0023] The stirring assembly 7 includes a stirring column 701, one end of which is rotatably connected to the lower end face of the sealing cover 2, and the other end of which is rotatably connected to the top wall of the positioning shell 4. A stirring block 702 is inserted through the bottom end of the stirring column 701, and the bottom end of the stirring block 702 is rotatably connected to the upper end face of the storage plate 6. A connecting rod 703 is integrally connected to the top end of the stirring block 702, and the connecting rod 703 is inserted into the stirring column 701.

[0024] It should be noted that the stirring block 702 is frustum-shaped, and multiple baffles 704 are integrally connected to the side wall of the stirring block 702. The top wall of the positioning shell 4 has a circular through hole 11 for the connecting rod 703 to pass through. The horizontal cross section of the connecting rod 703 is elliptical. The bottom end of the stirring column 701 has a groove 12 with a horizontal cross section that matches the connecting rod 703. When the pool water impacts the baffles 704 of the stirring column 701 or the stirring block 702 through the water inlet pipe 8, the stirring column 701 and the stirring block 702 rotate synchronously with the cooperation of the connecting rod 703 and the groove 12. The stirring column 701 stirs the pool water in the shell 1, making the pool water active and ensuring that hydroxyl groups are fully distributed in the pool water, thereby improving the bactericidal efficiency of hydroxyl groups.

[0025] The positioning shell 4 is a hollow frustum-shaped shell. With the cooperation of the positioning shell 4 and the stirring block 702, the catalyst is evenly distributed on the surface of the stirring block 702. At the same time, it can avoid the catalyst stacking, which would prevent the bottom catalyst from being exposed to the ultraviolet lamp 3 and thus resulting in low catalytic efficiency.

[0026] The side wall of the positioning shell 4 has multiple through holes 10, which allow for the replacement of the pool water inside the outer shell 1 with the pool water inside the cavity.

[0027] Before disinfecting the pool water, the sealing cover 2 is first removed. The sealing cover 2 is then removed by multiple rotating rods 5, which drive the positioning shell 4 and the storage plate 6 to be removed. The storage plate 6 is then rotated and removed. The catalyst is then placed on the lower end face of the positioning shell 4. The storage plate 6 is then installed on the lower end face of the positioning shell 4. Under the action of multiple baffles 704, the catalyst is evenly distributed in the cavity between the storage plate 6 and the positioning shell 4. Then, the water pump is started, allowing the pool water to enter the outer shell 1 through the water inlet pipe 8. When the pool water passes through the narrower section of the water inlet pipe 8, the flow rate of the pool water increases, which increases the impact force of the pool water on the stirring column 701 or stirring block 702. This is to accelerate the rotation speed of the stirring assembly 7. At the same time, the ultraviolet lamp 3 is turned on, and the ultraviolet lamp 3 irradiates the catalyst. Under the action of the catalyst, the rate of hydroxyl generation in the pool water is accelerated, and the hydroxyl groups are evenly distributed in the pool water by the stirring assembly 7, thereby improving the efficiency of disinfection and sterilization.
