Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a sterilization device for wastewater treatment. Background Technology

[0002] Wastewater treatment is an environmental governance process that uses physical, chemical, and biological technologies to remove pollutants (such as organic matter, suspended solids, nitrogen and phosphorus, heavy metals, pathogens, etc.) from domestic sewage, industrial wastewater, and agricultural runoff, so that the water quality meets discharge standards or reuse requirements. Its core objective is to reduce the pollution of water bodies and soil by wastewater, protect water resources and the ecological environment, and at the same time realize the recycling of water resources. Wastewater treatment can not only avoid problems such as black and smelly rivers, eutrophication of lakes, and groundwater pollution caused by direct discharge of wastewater, but also alleviate the pressure of water shortage. It is a key environmental project to ensure ecological security, improve the living environment, and promote sustainable development. In the wastewater treatment process, some types of wastewater, such as food processing wastewater, slaughterhouse wastewater, and municipal sewage pretreatment stage, contain a large amount of suspended solids (such as food residue, flocculent sludge, fibrous impurities, etc.). When the core sterilization element (ultraviolet lamp tube) of traditional sterilization devices comes into direct contact with the wastewater, the suspended solids easily adhere to the surface of the ultraviolet lamp tube to form a dirt layer. On the one hand, this will block the ultraviolet irradiation path, resulting in a significant decrease in sterilization efficiency. On the other hand, long-term accumulation of dirt will accelerate the corrosion and aging of the element, shorten its service life, and manual cleaning requires frequent shutdowns, increasing operation and maintenance costs and the risk of intermittent wastewater treatment. Therefore, a sterilization device for wastewater treatment is proposed to address the above problems. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0015] Please see Figures 1-6 This utility model provides a technical solution: A sterilization device for wastewater treatment includes a sterilization tank 1 and a tank cover 2 installed on the top of the sterilization tank 1. A water inlet pipe is connected to the top of one side of the sterilization tank 1, and a water outlet pipe is connected to the bottom of the other side of the sterilization tank 1. Multiple ultraviolet germicidal lamps 3 are arranged and fixedly installed at equal intervals on the top of the inner cavity of the sterilization tank 1. A driving component 4 is provided on the tank cover 2. A cleaning component 5 is provided on the outside of the ultraviolet germicidal lamps 3. A connecting component 6 is provided between the cleaning component 5 and the driving component 4. The cleaning component 5 includes a pair of cleaning arc plates 51. A cleaning pad 52 with a matching specification is provided on the inner arc surface of the cleaning arc plate 51. The ends of the two cleaning arc plates 51 are in contact and combined to form a complete cleaning sleeve. The cleaning arc plate 51 and the ultraviolet germicidal lamp 3 are coaxially arranged, and the inner arc surface of the cleaning pad 52 is in contact with the outer side of the ultraviolet germicidal lamp 3.

[0016] It should be noted that: the sterilization tank 1 provides a closed treatment space for sewage sterilization, and the inlet pipe and outlet pipe realize the inflow and outflow of sewage respectively. The ultraviolet sterilization lamp tube 3 kills bacteria in sewage by ultraviolet irradiation. The cleaning arc plate 51 of the cleaning component 5, together with the cleaning pad 52, can wrap the ultraviolet sterilization lamp tube 3 and wipe the stains on the outer wall of the lamp tube to avoid affecting the sterilization effect.

[0017] As a further implementation of this solution, the drive assembly 4 includes a drive bracket 41 fixedly connected to the top of the can lid 2. A reciprocating screw 42 is installed on the inner side of the drive bracket 41. A drive motor 43 with an output shaft connected to the reciprocating screw 42 is installed on one side of the drive bracket 41. A guide rod 44 located below the reciprocating screw 42 is installed on the inner side of the drive bracket 41. A reciprocating seat 45 connected to the reciprocating screw 42 is movably sleeved on the outer side of the guide rod 44. A connecting bracket 46 is fixedly connected to the bottom of the reciprocating seat 45.

[0018] It should be noted that the drive motor 43 of the drive assembly 4 drives the reciprocating lead screw 42 to rotate, causing the reciprocating seat 45 to move back and forth along the guide rod 44. Through the connecting bracket 46, the cleaning assembly 5 moves synchronously to achieve comprehensive cleaning of the ultraviolet germicidal lamp tube 3.

[0019] As a further implementation of this solution, the top of the can lid 2 is provided with a telescopic baffle 7 that moves in the same direction as the reciprocating screw 42. The connecting bracket 46 passes through the telescopic baffle 7 and is fixedly connected to the telescopic baffle 7. The bottom of the connecting bracket 46 extends into the inner cavity of the sterilization tank 1.

[0020] It should be noted that the telescopic cover 7 extends and retracts synchronously with the reciprocating motion of the connecting bracket 46, which can cover the gap between the drive component 4 and the tank cover 2 to prevent leakage during sewage sterilization.

[0021] As a further implementation of this solution, the connecting component 6 includes a connecting support plate 61 fixedly connected to the top outer side of the cleaning arc plate 51. A limiting groove 62 is provided on the upper part of the connecting support plate 61. Threaded holes 63 perpendicular to the setting direction of the ultraviolet germicidal lamp tube 3 are symmetrically provided on the bottom outer side of the connecting bracket 46. A connecting bolt 64 is threadedly connected to the threaded hole 63. A limiting plate 65 that matches the shape of the limiting groove 62 is fixedly connected to the outer end of the connecting bolt 64. An adjustment knob 66 ​​is fixedly connected to the outer side of the limiting plate 65. The limiting plate 65 and the adjustment knob 66 ​​pass through the limiting groove 62, and the limiting plate 65 is not aligned with the shape of the limiting groove 62 when connected.

[0022] It should be noted that the connecting component 6 fixes the connecting bracket 46 and the cleaning arc plate 51 by the misaligned engagement of the limiting plate 65 and the limiting through groove 62. The angle of the limiting plate 65 can be adjusted by rotating the adjustment knob 66, which facilitates the disassembly and replacement of the cleaning component 5.

[0023] Workflow: Before the device is put into use, basic assembly and functional debugging must be completed: Seal the tank lid 2 to the top of the sterilization tank 1 (install a rubber sealing ring to ensure no wastewater overflow), check the flexibility of the valves on the inlet and outlet pipes to ensure smooth wastewater flow; start the ultraviolet sterilization lamp 3, and confirm the lamp output is normal using an ultraviolet intensity detector to ensure the sterilization effect meets standards; debug the cleaning component 5: Connect the ends of a pair of cleaning arc plates 51 to form a complete cleaning sleeve to wrap around the ultraviolet sterilization lamp 3, ensuring the inner arc surface of the cleaning pad 52 (such as sponge material with strong adsorption) is tightly fitted to the outer side of the lamp tube, and connect the cleaning component 6. The connecting bracket 46 of component 5 and drive assembly 4 is fixed in the following manner: the connecting bolt 64 is always screwed into the threaded hole 63 of the connecting bracket 46 without separation. First, the adjustment knob 66 ​​is rotated to drive the connecting bolt 64 and the limiting plate 65 to rotate synchronously, so that the shape of the limiting plate 65 and the limiting through groove 62 of the connecting support plate 61 are aligned. After the limiting through groove 62 of the connecting support plate 61 passes through the limiting plate 65 and the adjustment knob 66, the adjustment knob 66 ​​is rotated again. The connecting support plate 61 is tightly attached to the connecting bracket 46 through the threaded connection of the connecting bolt 64 and the threaded hole 63, and the shape of the limiting plate 65 and the limiting through groove 62 is misaligned to achieve locking and fixing. Open the inlet valve to introduce the wastewater to be treated (such as domestic sewage or light industrial wastewater) into the sterilization tank 1. Keep the ultraviolet sterilization lamp 3 continuously powered on. The ultraviolet rays emitted by the lamp penetrate the wastewater and destroy the DNA structure of bacteria and viruses in the water, thus achieving sterilization and disinfection. During the process, the inlet and outlet pipes can maintain a small flow rate and run continuously (forming dynamic sterilization). Batch treatment can also be used (the tank is left to stand for sterilization after it is full, and the wastewater is discharged after it meets the standards). The specific method can be selected according to the treatment requirements. After sterilization, open the outlet valve to discharge the treated wastewater. At the same time, the wastewater sterilization effect is sampled and tested by water quality testing equipment. After it meets the standards, it can enter the subsequent treatment or discharge stage. When the ultraviolet germicidal lamp tube 3 runs continuously for a certain period of time, impurities and microbial residues (such as bacterial films) in the sewage are easily attached to the outer wall of the lamp tube, resulting in a decrease in ultraviolet light transmittance. At this time, the drive component 4 is started for cleaning: the drive motor 43 (such as a stepper motor with adjustable speed) is started, which drives the reciprocating screw 42 to rotate. Under the limiting action of the guide rod 44, the reciprocating seat 45 moves linearly back and forth along the reciprocating screw 42. The reciprocating seat 45 drives the bottom connecting bracket 46 to move back and forth synchronously. The connecting bracket 46 passes through the telescopic cover 7 (which moves and extends synchronously with the bracket, and is made of PVC, etc., to cover the gap between the drive component 4 and the tank cover 2 to prevent sewage leakage or water vapor from entering the drive component 4 and causing the parts to rust), and drives the cleaning component 5 connected to the connecting component 6 to move along the axial direction of the ultraviolet germicidal lamp tube 3. The cleaning arc plate 51 wraps around the lamp tube, and the cleaning pad 52 wipes the outer wall of the lamp tube during the movement to remove the attached impurities and bacterial films. The reciprocating movement cycle ensures that there are no residual stains on the outer wall of the lamp tube. When the cleaning pad 52 is severely worn or its adsorption capacity decreases, the cleaning component 5 needs to be disassembled and replaced: turn off the power of the device, rotate the adjustment knob 66 ​​to drive the connecting bolt 64 to rotate synchronously (the connecting bolt 64 is always screwed into the threaded hole 63 and does not separate), so that the shape of the limiting plate 65 is aligned with the limiting through groove 62 of the connecting support plate 61, and directly pull out the connecting support plate 61 along the direction of the limiting plate 65 to complete the separation; when installing the new cleaning component 5, first align the limiting plate 65 with the limiting through groove 62, insert the connecting support plate 61, and then rotate the adjustment knob 66 ​​to make the limiting plate 65 misaligned and engaged, ensuring that the cleaning pad 52 and the lamp tube are tightly attached.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
