DETAILED DESCRIPTION

[0027] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0028] First embodiment

[0029] See also Figure 1 The present invention provides a preparation process for long-term storage disinfectant sodium hypochlorite, comprising:

[0030] S101: mixing the sodium hypochlorite solution and the stabilizer to obtain a first mixed solution;

[0031] S102 adds a pH regulator to the first mixed solution to adjust the pH value of the solution to 8.0-10.5;

[0032] S103 adding a preservative and / or a surfactant to the solution after adjusting the pH value to obtain a second mixed solution;

[0033] S104 filters and clarifies the second mixed liquid to obtain disinfected sodium hypochlorite.

[0034] The stabilizer is selected from at least one of sodium silicate, sodium phosphate, sodium borate and sodium carbonate, and the added amount is 0.1%-5% of the mass of the sodium hypochlorite solution.

[0035] The pH regulator is sodium hydroxide, sodium bicarbonate or sodium citrate, and is used to adjust the pH to 9.0-10.0.

[0036] The preservative is sodium benzoate or potassium sorbate, and its content is 0.05% to 0.1% of the total mass of the solution.

[0037] The surfactant is sodium lauryl sulfate or polyoxyethylene ether nonionic surfactant, and the added amount is 0.01%-0.5% of the total mass of the solution.

[0038] During the preparation process, a sodium hypochlorite solution is mixed with a specific stabilizer and stirred thoroughly to form a first mixed solution. The stabilizer used here is selected from at least one of sodium silicate, sodium phosphate, sodium borate, and sodium carbonate, and is added in an amount of 0.1% to 5% by weight of the sodium hypochlorite solution. These stabilizers effectively prevent the decomposition of sodium hypochlorite, thereby ensuring the long-term stability of the final product. A pH adjuster is added to the first mixed solution to adjust the pH of the solution to 8.0-10.5, preferably within the range of 9.0-10.0. The pH adjuster can be sodium hydroxide, sodium bicarbonate, or sodium citrate. Precise pH control is crucial to maintaining the effectiveness and stability of sodium hypochlorite, as pH directly affects the molecular form and activity of sodium hypochlorite. A preservative and / or surfactant is further added to the pH-adjusted solution to form a second mixed solution. Preservatives are typically sodium benzoate or potassium sorbate, at a level of 0.05% to 0.1% by weight of the total solution, to inhibit microbial growth and prevent product deterioration during storage. The surfactant used is sodium lauryl sulfate or a polyoxyethylene ether nonionic surfactant, added at a rate of 0.01%-0.5% of the total solution mass. Surfactants help improve disinfection effectiveness by reducing the liquid's surface tension, allowing the disinfectant ingredients to disperse better and contact the target surface. The second mixed liquid is filtered and clarified to remove any possible particulate matter and other impurities, ensuring the purity and transparency of the final product, resulting in a high-quality disinfected sodium hypochlorite product. This meticulous post-processing step not only enhances the product's appearance but also helps extend its shelf life and ensures its safety and effectiveness during use.

[0039] The disinfectant sodium hypochlorite preparation process proposed in the present invention achieves high stability and long-term effectiveness of the sodium hypochlorite solution through carefully selected and proportioned stabilizers, pH adjusters, preservatives and surfactants, combined with strict process flow control, and is suitable for a wide range of disinfection application scenarios.

[0040] Second embodiment

[0041] See also Figures 2 to 7The present invention also provides a device for preparing disinfected sodium hypochlorite that can be stored for a long time, comprising an agitator and a filter, the filter comprising a base 101, a filter shell 102, a filter assembly 103 and a cleaning assembly 104, the filter shell 102 is fixed on the base 101, and a mounting slot 105 is provided on the filter shell 102, the filter assembly 103 comprises a rotating disk 106, a rotating motor 107, a plurality of support rods 108, a plurality of support frames 109, and a plurality of filter screens 110, the rotating disk 106 is rotatably arranged on one side of the filter shell 102, the output end of the rotating motor 107 is connected to the rotating disk 106, a plurality of support rods 108 are fixed to the rotating disk 106, a plurality of support frames 109 are respectively connected to the plurality of support rods 108, a plurality of filter screens 110 are arranged in the plurality of support frames 109, and the cleaning assembly 104 is arranged on one side of the rotating disk 106 for cleaning the filter screens 110.

[0042] In this embodiment, the filter's foundation is provided by a sturdy base 101, to which a filter housing 102 is securely fastened. Filter housing 102 not only serves as the outer shell of the entire assembly but also provides necessary protection and support. Specifically, a mounting groove 105 is provided on filter housing 102 for precise mounting and sealing of filter assembly 103, ensuring a tight fit and efficient operation between all components.

[0043] The core of filter assembly 103 is rotating disc 106, which is mounted on one side of filter housing 102 via precision bearings, allowing for smooth and flexible rotation. The output of motor 107 is directly connected to rotating disc 106, providing power and ensuring that rotating disc 106 rotates at a predetermined speed and direction.

[0044] Multiple support rods 108 are fixed to the rotating disk 106. These rods 108 not only provide physical support but also serve as a key channel for transmitting the rotational force. Each support rod 108 is connected to a support frame 109, designed for durability and ease of replacement. Each support frame 109 houses a specially designed filter 110. Made of high-precision materials, these filters 110 effectively trap tiny particles and other impurities while allowing liquid to pass freely, ensuring the purity and transparency of the final product.

[0045] During use, impurities in the filter housing 102 are filtered through the filter 110. After a period of use, the filter 110 needs to be cleaned. At this time, the rotating disk 106 is started to rotate to drive another filter 110 into the installation groove 105, and the filter 110 to be cleaned is close to the cleaning component 104. At this time, the filter 110 can be cleaned by the cleaning component 104, so that the filter 110 can be cleaned conveniently to improve work efficiency.

[0046] The filter housing 102 includes a housing 111, a first sealing ring 112, a pressure ring 113, a second sealing ring 114 and a control cylinder 115. The first sealing ring 112 is arranged at the bottom of the mounting groove 105, the pressure ring 113 is slidably arranged at the top of the mounting groove 105, the second sealing ring 114 is fixed to the top of the pressure ring 113, and the output end of the control cylinder 115 is connected to the pressure ring 113.

[0047] As the filter's foundational structure, housing 111 provides essential physical support and protection. It is designed to withstand certain pressure and temperature fluctuations, ensuring stable operation of internal components in a variety of operating environments. Housing 111 is typically constructed of corrosion-resistant materials to resist attack by sodium hypochlorite solutions and other chemicals, extending the life of the device.

[0048] In order to ensure a tight connection between the filter assembly 103 and the housing 111 and avoid leakage, a first sealing ring 112 is provided at the bottom of the mounting groove 105. The sealing ring is made of a highly elastic material and has good sealing performance and anti-aging ability.

[0049] The pressure ring 113 is slidably mounted on the top of the mounting groove 105. Its function is to fix the filter assembly 103 by applying uniform pressure, ensuring that all filter screens 110 are firmly positioned in their designated positions, thereby improving filtration efficiency and improving sealing to prevent disinfected sodium hypochlorite from leaking from gaps.

[0050] The second sealing ring 114 fixed to the top of the pressure ring 113 further enhances the sealing effect of the system. When the pressure ring 113 moves downward, the second sealing ring 114 will cling to the upper edge of the filter assembly 103, forming an additional sealing layer, effectively blocking any possible leakage path.

[0051] By controlling the movement of the air cylinder 115, the position of the pressure ring 113 can be precisely adjusted, thereby adjusting the pressure on the filter assembly 103. This not only makes the installation and removal of the filter assembly 103 more convenient, but also enables the sealing force to be dynamically adjusted according to actual needs during the filtration process to ensure the best filtration effect.

[0052] The support rod 108 includes a rod body 116, a rotating rod 117 and a control gear 118. The rod body 116 is fixed to the rotating disk 106, the rotating rod 117 is rotatably connected to the rod body 116, and the control gear 118 is fixed to the rotating rod 117. The filter assembly 103 also includes a drive gear 119 and a drive motor 120. The drive motor 120 is arranged on one side of the cleaning assembly 104. The drive gear 119 is connected to the output end of the drive motor 120. When the support rod 108 moves to a preset position, the drive gear 119 engages with the control gear 118.

[0053] Rod 116 is securely fastened to rotating disk 106. It not only bears the weight of filter assembly 103 but also ensures stability during high-speed rotation, preventing any potential imbalance or damage to the equipment. Rod 116 is typically constructed of high-strength materials to meet strength and durability requirements under various operating conditions.

[0054] The rotating rod 117 is connected to the rod body 116 by a rotational connection, allowing the rotating rod 117 to rotate freely relative to the rod body 116. A control gear 118 is fixedly mounted on the rotating rod 117 and is a key component for achieving automated control. By precisely meshing with the drive gear 119, the control gear 118 transmits power from the drive motor 120 to the rotating rod 117, thereby achieving precise rotation of the rotating rod 117.

[0055] Drive motor 120 is mounted on one side of cleaning assembly 104. It serves as a power source, with its output directly connected to drive gear 119. When support rod 108 moves to a preset position, drive gear 119 engages with control gear 118, and drive motor 120 begins to operate, rotating control gear 118 and its connected rotating rod 117. This allows filter 110 to be rotated 180° during cleaning, improving cleaning efficiency.

[0056] The cleaning assembly 104 includes a longitudinal mover, a first mover 121, a mounting block 122, a nozzle 123, a cleaning brush 124 and a collection box 125. The collection box 125 is arranged on one side of the rotating disk 106, the longitudinal mover is slidably arranged on one side of the collection box 125, the first mover 121 is slidably arranged on the longitudinal mover, the mounting block 122 is arranged on the first mover 121, the nozzle 123 is arranged on the mounting block 122, and the cleaning brush 124 is arranged on one side of the nozzle 123.

[0057] Located on one side of the rotating disk 106, the collection box 125 receives impurities and dirt removed from the filter 110. Its design takes into account capacity and ease of cleaning, ensuring effective waste storage during long-term operation and preventing secondary contamination or clogging. The collection box 125 is typically made of corrosion-resistant materials to withstand various chemical attacks.

[0058] The longitudinal mover can adjust the longitudinal height of the cleaning brush 124, while the first mover 121 is used to adjust the lateral position of the cleaning brush 124. When the filter 110 is flipped, the longitudinal mover lifts the cleaning brush 124 to a preset height. After the filter 110 is flipped, the longitudinal mover resets, allowing the cleaning brush 124 to contact the filter 110. The nozzle 123 is then activated to clean the filter 110, while the first mover 121 drives the cleaning brush 124 to clean the filter 110, thereby better cleaning the filter 110.

[0059] The cleaning brush 124 includes a triangular block 126 , a second elastic member 127 and a brush body 128 . The triangular block 126 is slidably arranged on the mounting block 122 . The second elastic member 127 is used to support the triangular block 126 . The brush body 128 is rotatably arranged on the triangular block 126 .

[0060] The triangular block 126 flexibly adjusts its position according to the specific conditions of the surface of the filter 110 to ensure that the brush body 128 always maintains the best contact angle with the filter 110. The triangular block 126 is usually made of a strong and lightweight material to ensure sufficient strength while reducing the overall weight, so that the first mover 121 can accurately control its movement. The elastic member is used to support the triangular block 126 and provide necessary elastic compensation. When the cleaning brush 124 contacts the filter 110, the second elastic member 127 can automatically adjust the height of the triangular block 126 so that it fits tightly to the surface of the filter 110. Even in the face of an uneven or slightly deformed filter 110, it can ensure uniform pressure distribution, avoiding damage to the filter due to excessive pressure or incomplete cleaning due to too little pressure.

[0061] The brush body 128 is the part that directly contacts the filter 110 and is rotatably mounted on the triangular block 126. This design allows the brush body 128 to rotate during cleaning, effectively removing stubborn stains and deposits from the filter 110. The material selection for the brush body 128 is crucial; it must be sufficiently hard to effectively remove impurities while not damaging the structure of the filter 110.

[0062] Third embodiment

[0063] The present invention also provides a formula of disinfectant sodium hypochlorite capable of long-term storage, and adopts the preparation process of disinfectant sodium hypochlorite capable of long-term storage.

[0064] Sodium hypochlorite solution, the primary active ingredient, dissociates in water to produce hypochlorous acid (HOCl), which has a powerful oxidizing ability and can effectively kill a variety of pathogenic microorganisms, including bacteria, viruses, and fungi. Selecting high-purity sodium hypochlorite is key to ensuring the quality of the final product. To enhance the stability of the sodium hypochlorite solution and prevent it from decomposing and becoming ineffective, a stabilizer is added to the formula in a specific proportion. This stabilizer is selected from at least one of sodium silicate, sodium phosphate, sodium borate, and sodium carbonate, and is added in an amount of 0.1% to 5% by weight of the sodium hypochlorite solution. Its function is to inhibit the decomposition of sodium hypochlorite through chemical reactions, thereby extending the shelf life of the product. The pH value has a significant impact on the stability and disinfection efficiency of sodium hypochlorite. Therefore, sodium hydroxide, sodium bicarbonate, or sodium citrate is used as a pH adjuster in the formula to precisely adjust the solution's pH to 8.0-10.5, preferably in the range of 9.0-10.0. A suitable pH environment helps maintain the existence of sodium hypochlorite molecules and their optimal activity.

[0065] To prevent microbial contamination during storage, preservatives such as sodium benzoate or potassium sorbate are added, with their content controlled at 0.05% to 0.1% of the total solution mass. These preservatives can effectively inhibit the growth and reproduction of microorganisms such as mold and yeast, ensuring the hygienic safety of the product. To improve the diffusion and coverage of the disinfectant during use, it is necessary to add a small amount of surfactant. Commonly used surfactants include sodium lauryl sulfate or polyoxyethylene ether nonionic surfactants, added at a level of 0.01% to 0.5% of the total solution mass. This not only promotes good contact between the liquid and the surface to be disinfected, but also helps remove grease and other contaminants, enhancing the disinfection effect.

[0066] The mixed liquid is rigorously filtered and clarified to remove any possible tiny particles or other impurities, ensuring the purity and transparency of the final product. This process is crucial for improving the product's appearance and extending its shelf life.

[0067] The disinfectant sodium hypochlorite formula and corresponding preparation process provided by the present invention can produce a product with excellent stability and efficient disinfection capabilities. This disinfectant is not only suitable for various daily disinfection scenarios, such as household cleaning and public sanitation maintenance, but can also be widely used in medical facilities, food processing and other fields. Its long-lasting storage properties eliminate the need for frequent inventory changes, reducing management and operating costs, and also reducing the risk of product deterioration.

[0068] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of the rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
