[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0032] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The specific implementation of the present invention is described in detail below with reference to specific embodiments. Example 1

[0034] See also Figures 1 to 4 , provides a supporting pure water station wastewater sterilization equipment for caustic soda production, including an equipment machine 11 and an equipment machine box 10 mounted on the equipment machine 11; the equipment machine 11 includes a first water inlet compartment 12, a second water inlet compartment 13 and a water outlet compartment 14 arranged between the first water inlet compartment 12 and the second water inlet compartment 13, and the water outlet compartment 14 is externally connected to an output machine pump 15; the main body of the equipment machine box 10 is a water treatment main box 19, and outer wing frame shells 16 are provided on both sides of the water treatment main box 19. A second circulating pump 17 and a first circulating pump 18 are respectively mounted on the outer wing frame shells 16 on both sides, and the water inlet ends of the second circulating pump 17 and the first circulating pump 18 are respectively connected to the second water inlet compartment 13 and the first water inlet compartment 12;

[0035] The water treatment main box 19 includes a sterilization treatment area 21, a top frame box 22 arranged at the top of the sterilization treatment area 21, and a first water guide area 23 and a second water guide area 24 arranged on both sides of the sterilization treatment area 21; the top frame box 22 is fixedly installed on the box frame of the sterilization treatment area 21, and the output ends of the second circulating pump 17 and the first circulating pump 18 are respectively connected to the first water guide area 23 and the second water guide area 24, and the first water guide area 23 and the second water guide area 24 are connected to the sterilization treatment area 21; an output hopper 25 is provided at the bottom of the sterilization treatment area 21, and the output hopper 25 is provided between the equipment machine 11 and the equipment chassis 10 and is connected to the water outlet compartment 14.

[0036] The equipment machine 11 serves as the supporting structure of the entire wastewater treatment system. The equipment machine 11 is made of sturdy and durable materials to ensure long-term stable operation. The first water inlet chamber 12 and the second water inlet chamber 13 can be designed with different capacities and filtering devices to adapt to wastewater from different sources and properties. Both water inlet chambers are equipped with preliminary filtration systems, such as screens, sand filters, etc., for removing large particles of impurities and suspended matter in the wastewater. In addition, the first water inlet chamber 12 and the second water inlet chamber 13 are each equipped with an ultraviolet sterilization device to perform preliminary sterilization treatment on the wastewater before it enters the equipment chassis 10, reducing the burden of subsequent treatment.

[0037] The main body of the equipment chassis 10 is the water treatment main box 19, which is divided into multiple functional areas. The outer wing frame shell 16 not only provides support and shock absorption for the second circulating pump 17 and the first circulating pump 18, but also the second circulating pump 17 and the first circulating pump 18 respectively extract the preliminarily treated wastewater from the second water inlet chamber 13 and the first water inlet chamber 12, and send them to the first water guide section 23 and the second water guide section 24. The two water guide sections can also be equipped with guide plates to ensure that the wastewater can be evenly distributed and flow smoothly into the sterilization treatment section 21. The top of the top frame box 22 is equipped with a control system and an alarm device. When the equipment fails or the water quality is abnormal, it can promptly issue an alarm to the operator. The output hopper 25 is located at the bottom of the sterilization treatment section 21 and is designed with an inclination angle to facilitate the smooth flow of treated wastewater into the water outlet chamber 14. Finally, the output pump 15 discharges the sterilized wastewater.

[0038] The sterilization treatment area 21 is the core of the equipment chassis 10. An ozone supply unit 26 is installed within the top frame box 22. Ozone's strong oxidizing properties allow it to rapidly decompose organic matter in wastewater and kill bacteria, viruses, and other microorganisms. The sterilization treatment area 21 is equipped with a built-in frame 27 and ultraviolet main lamps 28 mounted on both sides of the built-in frame 27. The illumination end of the ultraviolet main lamp 28 is located at the output port 102 of the ozone supply unit 26. The built-in frame 27 is made of corrosion-resistant, high-strength material to support the ultraviolet main lamp 28 and ensure its stable operation. Ultraviolet rays can destroy the DNA structure of microorganisms, thereby achieving the effect of killing bacteria, viruses, and other microorganisms. The illumination end of the ultraviolet main lamp 28 is specially designed at the output port 102 of the ozone supply unit 26 so that ozone gas and ultraviolet rays can act on the wastewater simultaneously, creating a synergistic sterilization effect, greatly improving sterilization efficiency and effectiveness.

[0039] By employing multiple filtration and sterilization systems, the equipment can effectively eliminate bacteria, viruses, and other microorganisms in wastewater. Combined with the sterilization effects of the ozone generator 26 and the main ultraviolet lamp 28, this equipment creates a synergistic sterilization effect, significantly improving sterilization efficiency and effectiveness. This dual sterilization approach ensures that bacteria, viruses, and other microorganisms in wastewater are effectively eliminated, ensuring that the effluent water quality meets relevant national standards and meets the water requirements of caustic soda production. Example 2

[0040] See also Figure 2 、 Figure 5 and Figure 6 This embodiment is a further design of the above embodiment. On this basis, the specific implementation structure of the second water inlet compartment 13 or the first water inlet compartment 12 is designed as follows:

[0041] The inner spaces of the second water inlet chamber 13 and the first water inlet chamber 12 are divided into a partition chamber 32 and a water filter chamber 33. A filter frame 31 is provided between the partition chamber 32 and the water filter chamber 33. The water inlet pipes of the second turnover pump 17 and the first turnover pump 18 extend into the corresponding water filter chamber 33. The filter frame 31 includes a middle support frame 41, a side mounting plate 42 provided on the side edge of the middle support frame 41, and a filter panel 43 provided on the middle support frame 41. The second water inlet chamber 13 and the first water inlet chamber 12 are both designed as a double-layer structure, and the inner space is separated by the partition chamber 32 and the water filter chamber 33. The filter panel 43 is made of high-precision filter mesh material, which can effectively intercept suspended matter, impurities, etc. in the wastewater.

[0042] The inner cavity of the separation chamber 32 is provided with a water inlet 34, and the output end of the water inlet 34 is provided with a water inlet fence 35. Under the action of the water inlet fence 35, preliminary filtration is performed to remove larger particles; the filter frame 31 performs secondary filtration to intercept the sediment in the separation chamber 32, and the water inlet end pipes of the second circulating pump 17 and the first circulating pump 18 extend into the corresponding water filter chamber 33, and the filtered water is sent to the water treatment main box 19.

[0043] The tops of both the second and first water inlet compartments 13 and 12 are equipped with an internal light frame 36 and a UV light panel 37 mounted on the internal light frame 36. As wastewater passes through the filter chamber 33, the UV light panel 37 emits ultraviolet light that effectively kills bacteria, viruses, and other microorganisms in the wastewater. Through the dual functions of the filter frame 31 and the UV light panel 37, impurities and microorganisms in the wastewater are initially removed.

[0044] A sediment discharger 38 is mounted on the side of the partition chamber 32. The sediment discharger 38 comprises an outer wing bracket 44 and several spiral sewage pumps 45 mounted on the outer wing bracket 44. The outer wing bracket 44 is fixed to the frame wall of the first water inlet compartment 12 or the second water inlet compartment 13. This allows for the regular removal of sewage deposited at the bottom of the partition chamber 32 to prevent clogging. Example 3

[0045] See also Figure 4 、 Figure 7 and Figure 9 This embodiment is a further design of the above embodiment. On this basis, the installation and implementation structure of the ozone supply machine 26 and the ultraviolet main lamp 28 is designed as follows:

[0046] The built-in frame 27 includes a fixed frame 51, a slide bar 52 installed at the four corners of the fixed frame 51, and a bottom plate 53 fixed to the bottom end of the slide bar 52; the fixed frame 51 is fixedly installed in the top frame box 22; the built-in frame 27 also includes a lifting frame 54, and the lifting frame 54 is slidably installed on the slide bar 52 through a sliding sleeve 55; the ozone supply machine 26 includes a hoisting frame 81 and a supply box 82 installed on the hoisting frame 81, and the supply box 82 is installed in a lifting manner on the inner frame of the hoisting frame 81, and synchronous frames 83 are provided at both ends of the supply box 82, and the synchronous frames 83 are mounted on the lifting frame 54; the ultraviolet main lamp 28 is installed on the other two sides of the lifting frame 54.

[0047] The fixed frame 51 serves as the foundational support structure for the entire frame. Four slide bars 52 are mounted at the four corners of the fixed frame 51. They extend vertically downward, providing sliding tracks for the lifting frame 54. The ozone supply unit 26 is mounted on a hoisting frame 81, which is strong and stable enough to support the weight and lifting motion of the supply chassis 82. The main UV lamp 28 is mounted on either side of the lifting frame 54. The UV lamp 28 and the supply chassis 82 are raised and lowered synchronously via the lifting frame 54, ensuring a continuous and stable ozone supply.

[0048] Ultraviolet lamps primarily utilize ultraviolet radiation energy to destroy the nucleic acid structure of microorganisms, thereby killing bacteria, viruses, and other microorganisms. However, ultraviolet radiation disinfection has limited penetration and may not be able to achieve complete disinfection. Therefore, this embodiment supplements ultraviolet lamp sterilization with ozone sterilization, creating a complementary sterilization effect. Ultraviolet lamps can directly destroy the nucleic acid structure of microorganisms, while ozone can penetrate into the cells of microorganisms, further damaging their structure and function. In addition, the diffusive nature of ozone can also compensate for the blind spots that may exist during ultraviolet lamp disinfection.

[0049] In one case of this embodiment, for the driving implementation of the lifting frame 54, please refer to Figure 7 and Figure 8 , this embodiment is designed as follows:

[0050] The built-in frame 27 also includes a transmission screw 61 and a power input rod 62 connected to the transmission screw 61. The transmission screw 61 is inserted into the lifting frame 54 and is connected to the lifting frame 54 by a thread; the box body of the water treatment main box 19 is also provided with a mounting base 71, and a drive motor 72 is installed on the mounting base 71. The rod end of the power input rod 62 is connected to the driving end of the drive motor 72 through a coupling 73. Both ends of the power input rod 62 are provided with a transmission sleeve 74, and a transmission gear 75 is installed on the transmission sleeve 74. The bottom end of the transmission screw 61 is provided with a driven head 76, and a driven tooth pattern 77 is installed on the driven head 76. The transmission gear 75 is tooth-meshed with the driven tooth pattern 77.

[0051] This embodiment uses a drive motor 72 as a power source. The drive motor 72 drives the power input rod 62, which in turn drives the transmission screw 61 through gear meshing. This in turn drives the lifting frame 54 up and down, thereby driving the appropriate movement of the UV main lamp 28 and the supply chassis 82. During this movement, ozone gas is more effectively dispersed into the wastewater, allowing the ozone and wastewater to be fully mixed, thereby improving the reaction rate and sterilization efficiency.

[0052] In one embodiment of the present invention, see Figure 10 , regarding the specific implementation structure of the ozone supply machine 26, this embodiment is designed as follows:

[0053] The ultraviolet main lamp 28 includes an ultraviolet spotlight frame 91, an irradiation surface 92 arranged at the inner end of the ultraviolet spotlight frame 91, and a plurality of spotlight panels 94 installed in the area of the irradiation surface 92. The side edge of the ultraviolet spotlight frame 91 is provided with a swing support 93, and the spotlight panels 94 are all installed on the swing support 93. The spotlight panels 94 are arranged in a stepped manner along the irradiation surface 92.

[0054] The spotlight panels 94 are the core components of the main UV lamps 28 and are evenly mounted within the irradiation surface 92. Each panel 94 contains one or more UV lamps that emit high-intensity UV radiation, killing bacteria, viruses, and other microorganisms in the wastewater. The panels 94 are mounted to the UV lamp frame 91 via swing supports 93. The design of the swing supports 93 allows the panels 94 to be arranged in a stepped pattern across the irradiation surface 92. This not only improves UV coverage but also ensures uniform UV radiation exposure to the wastewater as it flows through.

[0055] In one embodiment of the present invention, see Figure 10 and Figure 11 Regarding the specific implementation structure of the supply chassis 82, this embodiment is designed as follows:

[0056] An ozone output frame 101 is provided at the bottom of the supply chassis 82, and an output port 102 is opened on the ozone output frame 101. A plurality of diverter branches 103 are installed in the slot of the output port 102; the diverter branches 103 include a movable support shaft 111 installed between the slot walls of the output port 102, and a swing plate 112 and a cutting wheel 113 installed on the movable support shaft 111. The cutting wheel 113 is arranged on both sides of the swing plate 112.

[0057] The supply box 82 is the main body of the entire ozone supply system, which integrates the ozone generator and its related electrical control system. The ozone generator produces ozone gas by electrolysis or discharge, and these gases are collected and transported to the ozone output box 101.

[0058] The ozone output frame 101 is located at the bottom of the supply chassis 82, and the diverter branch 103 is responsible for further dispersing the ozone gas from the output port 102 into the wastewater. The design of the oscillating disc 112 can increase the contact area between the ozone gas and the wastewater, thereby improving the sterilization efficiency. When the ozone gas flows out from the output port 102, it pushes the oscillating disc 112 and the cutting flow wheel 113 to swing, further dispersing the ozone gas into the wastewater. The cutting flow wheel 113 is a rotating component with sharp edges, which is located on both sides of the oscillating disc 112. When the ozone gas passes through, the rotation of the cutting flow wheel 113 will generate a strong shear force, cutting the ozone gas into smaller bubbles, thereby increasing its contact area with the wastewater and improving the reaction rate.

[0059] At the same time, the above-mentioned diversion branch 103 also has a certain impact on the wastewater flow, driving the wastewater flow to be distributed from the center line to both sides, forming water waves moving toward the spotlight panels 94 on both sides, thereby improving the contact effect between the water flow and the ultraviolet spotlight and reducing the working impact caused by the poor ultraviolet penetration effect.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.

[0061] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
