Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments. Embodiment 1

[0032] See also Figures 1 to 4 , a supporting pure water station wastewater sterilization equipment for caustic soda production is provided, including an equipment platform 11 and an equipment chassis 10 mounted on the equipment platform 11; the equipment platform 11 includes a first water inlet chamber 12, a second water inlet chamber 13 and a water outlet chamber 14 arranged between the first water inlet chamber 12 and the second water inlet chamber 13, and the water outlet chamber 14 is externally connected to an output machine pump 15; the main body of the equipment chassis 10 is a water treatment main box 19, and outer wing frame shells 16 are arranged on both sides of the water treatment main box 19, and 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 chamber 13 and the first water inlet chamber 12; The water treatment main box 19 includes a sterilization treatment area 21, a top frame box 22 arranged on 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 bucket 25 is arranged at the bottom of the sterilization treatment area 21, and the output bucket 25 is arranged between the equipment platform 11 and the equipment chassis 10 and is connected to the water outlet compartment 14.

[0033] 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 particle impurities and suspended matter in the wastewater. In addition, the first water inlet chamber 12 and the second water inlet chamber 13 are also 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.

[0034] The main body of the equipment chassis 10 is the main water treatment 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 provided with guide plates to ensure that the wastewater can be evenly distributed and smoothly flow into the sterilization treatment section 21. The top of the top frame box 22 is equipped with a control system, and an alarm device can also be provided to promptly send an alarm to the operator when the equipment fails or the water quality is abnormal. 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 the treated wastewater into the water outlet chamber 14. Finally, the output pump 15 discharges the sterilized wastewater.

[0035] The sterilization treatment area 21 is the core part of the equipment chassis 10. The top frame box 22 is provided with an ozone supply machine 26. The strong oxidizing property of ozone can quickly decompose organic matter in wastewater and kill bacteria, viruses and other microorganisms. The sterilization treatment area 21 is provided with a built-in frame 27 and an ultraviolet main lamp 28 installed 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 machine 26.

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 machine 26, so that ozone gas and ultraviolet rays can act on the wastewater at the same time, forming a synergistic sterilization effect, greatly improving the sterilization efficiency and effect.

[0036] By adopting multiple filtration systems and multiple sterilization systems, bacteria, viruses and other microorganisms in wastewater can be efficiently killed; combined with the sterilization effect of the ozone supply machine 26 and the ultraviolet main lamp 28, this equipment can form a synergistic sterilization effect, greatly improving the sterilization efficiency and effect.

Embodiment 2

[0037] See also Figure 2 , Figure 5 and Figure 6 This embodiment is a further design of the above embodiment. On this basis, for the specific implementation structure of the second water inlet compartment 13 or the first water inlet compartment 12, this embodiment is designed as follows: The inner space of the second water inlet chamber 13 and the first water inlet chamber 12 is divided into a partition chamber 32 and a water filter chamber 33. A filter frame 31 is arranged between the partition chamber 32 and the water filter chamber 33. The water inlet pipes of the second circulating pump 17 and the first circulating 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 arranged on the side edge of the middle support frame 41, and a filter panel 43 arranged 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 internal space is divided by the partition chamber 32 and the water filter chamber 33, wherein the filter panel 43 adopts a high-precision filter material, which can effectively intercept suspended matter, impurities, etc. in the wastewater.

[0038] 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 to send the filtered water to the water treatment main box 19.

[0039] The top of the frame of the second water inlet chamber 13 and the first water inlet chamber 12 are both provided with an internal light frame 36 and an ultraviolet light board 37 installed on the internal light frame 36; when the wastewater passes through the water filter chamber 33, the ultraviolet light emitted by the ultraviolet light board 37 can effectively kill microorganisms such as bacteria and viruses in the wastewater. Through the dual effects of the filter frame 31 and the ultraviolet light board 37, impurities and microorganisms in the wastewater are preliminarily removed.

[0040] A sediment discharger 38 is installed on the side edge of the partition chamber 32, and the sediment discharger 38 includes an outer wing bracket 44 and a plurality of spiral sewage pumps 45 installed on the outer wing bracket 44. The outer wing bracket 44 is fixed on the frame wall of the first water inlet chamber 12 or the second water inlet chamber 13. The sewage deposited at the bottom of the partition chamber 32 can be pumped out regularly to prevent blockage. Embodiment 3

[0041] See also Figure 4 , Figure 7 and Fig. 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: 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 machine frame 81 and a supply box 82 installed on the hoisting machine frame 81, the supply box 82 is installed on the inner frame of the hoisting machine frame 81 in a lifting manner, 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.

[0042] The fixed frame 51 is the basic support structure of the entire frame. Four slide bars 52 are respectively installed at the four corners of the fixed frame 51. They extend vertically downward to provide sliding tracks for the lifting frame 54. The ozone supply machine 26 uses the hoisting frame 81 as the installation outer frame. The hoisting frame 81 has sufficient strength and stability to support the weight and lifting movement of the supply chassis 82. The ultraviolet main lamp 28 is installed on the other two sides of the lifting frame 54. The ultraviolet main lamp 28 and the supply chassis 82 are kept in synchronous lifting through the lifting frame 54 to ensure the continuity and stability of the ozone supply.

[0043] Ultraviolet lamps mainly use the radiation energy of ultraviolet rays to destroy the nucleic acid structure of microorganisms, thereby achieving the purpose of killing bacteria, viruses and other microorganisms; however, the penetration ability of ultraviolet irradiation disinfection is limited, and it may not be possible to achieve dead-angle disinfection. Therefore, this embodiment supplements the ultraviolet lamp sterilization with ozone sterilization to form a complementary sterilization effect. Ultraviolet lamps can directly destroy the nucleic acid structure of microorganisms, while ozone can penetrate into the cells of microorganisms and further destroy their structure and function. In addition, the diffuseness of ozone can also make up for the dead angle problem that may exist during ultraviolet lamp irradiation disinfection.

[0044] 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: 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 plate 71, and a drive motor 72 is installed on the mounting base plate 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, and transmission sleeves 74 are provided at both ends of the power input rod 62. 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.

[0045] This embodiment uses a driving motor 72 as a power source, the driving motor 72 drives the power input rod 62 to move, the power input rod 62 drives the transmission screw 61 to move through gear meshing transmission, and then drives the lifting frame 54 to move up and down, thereby driving the ultraviolet main lamp 28 and the supply chassis 82 to make appropriate movements. During the movement process, the ozone gas can be more effectively dispersed into the wastewater, so that the ozone and the wastewater are fully mixed, and the reaction rate and sterilization efficiency are improved.

[0046] In one case of this embodiment, see Fig.10 , for the specific implementation structure of the ozone supply machine 26, this embodiment is designed as follows: 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.

[0047] The spotlight panels 94 are the core components of the main ultraviolet lamp 28, and they are evenly installed in the area of ​​the irradiation surface 92. Each spotlight panel 94 contains one or more ultraviolet lamp tubes, which emit high-intensity ultraviolet radiation to kill bacteria, viruses and other microorganisms in the wastewater. The spotlight panels 94 are installed on the ultraviolet spotlight frame 91 through the swing support 93. The design of the swing support 93 allows the spotlight panels 94 to be arranged in a stepped manner on the irradiation surface 92, which not only improves the coverage of ultraviolet rays, but also ensures that the wastewater is evenly irradiated with ultraviolet rays during the flow.

[0048] In one case of this embodiment, see Fig.10 and Fig.11 , for the specific implementation structure of the supply chassis 82, this embodiment is designed as follows: 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, and 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 flow cutting wheel 113 installed on the movable support shaft 111, and the swing plate 112 is arranged on both sides of the flow cutting wheel 113.

[0049] The supply box 82 is the main body of the whole ozone supply system, and the ozone generator and its related electrical control system are integrated inside it. The ozone generator generates ozone gas by electrolysis or discharge, etc., and these gases are collected and transported to the ozone output box 101.

[0050] Ozone output frame 101 is located at the bottom of supply chassis 82, and diversion branch 103 is responsible for further dispersing ozone gas into wastewater from output port 102. The design of swing plate 112 can increase the contact area between ozone gas and wastewater, thereby improving sterilization efficiency. When ozone gas flows out from output port 102, it will push swing plate 112 and cutting flow knife wheel 113 to swing, further dispersing ozone gas into wastewater. Cutting flow knife wheel 113 is a rotating part with sharp edge, and it is located between swing plates 112. When ozone gas passes through, the rotation of cutting flow knife wheel 113 will produce strong shear force, cut ozone gas into smaller bubbles, thereby increasing its contact area with wastewater, improving reaction rate.

[0051] 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 work impact caused by the poor ultraviolet penetration effect.

[0052] 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 present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0053] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description 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 may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
