Description

Technical Field

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

[0002] Wastewater treatment includes wastewater incineration, organic wastewater treatment, or organic industrial wastewater treatment, also known as high-concentration organic wastewater treatment. Treatment methods include physical, chemical, and biological methods. Chemical treatment is often combined with physical processes, hence the term physicochemical treatment. Physical treatment refers to treating wastewater using physical or mechanical separation methods, such as filtration, sedimentation, flotation, oil separation, and centrifugation. Chemical treatment separates and removes dissolved or colloidal pollutants from wastewater or converts them into harmless substances through chemical reactions and mass transfer. Biological treatment utilizes the metabolic activity of microorganisms to transform organic pollutants in solution, colloidal, and finely suspended states into stable, harmless substances.

[0003] Existing disinfection devices for waste liquid treatment use basic stirring methods to mix waste liquid and disinfectant or use ultraviolet irradiation for disinfection. If the waste liquid is not mixed evenly, some areas of waste liquid may not be fully exposed to ultraviolet light, resulting in the microorganisms in these areas not being completely killed, affecting the overall disinfection effect. On the contrary, some areas may undergo unnecessary chemical changes due to excessive irradiation, wasting energy and potentially producing harmful byproducts.

[0004] Meanwhile, if the disinfectant and waste liquid are not mixed evenly, the microorganisms in the waste liquid where the disinfectant is not mixed will not be completely killed. This will increase the survival rate of pathogens in the waste liquid and fail to achieve the expected disinfection effect. Therefore, the existing disinfection devices for waste liquid treatment need to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a disinfection device for waste liquid treatment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a disinfection device for waste liquid treatment, comprising a disinfection tank, a cap installed on the top of the disinfection tank, an inlet pipe installed through the inner wall of the cap, a conveying pipe installed through the outer wall of the disinfection tank, a motor fixedly connected to the bottom of the disinfection tank, and a transmission rod connected to the output shaft of the motor via a coupling, a first bevel gear fixedly connected to the outer wall of the transmission rod, a second bevel gear meshing with the outer wall of the first bevel gear, a fixing rod fixedly connected to the inner wall of the second bevel gear, and a stirrer fixedly connected to the outer wall of the fixing rod, a push plate installed on one side of the stirrer, and a stirring rod fixedly connected to the top of the stirrer, and a drain pipe installed through the outer wall of the disinfection tank.

[0007] Preferably, a pull rod is fixedly connected to the top of the cover, and the cover forms a tension structure through the pull rod. A hook is engaged at the bottom of the cover, and a connecting rod is fixedly connected to the other end of the hook.

[0008] Preferably, a filter frame is fixedly connected to the other end of the connecting rod, and a slider is fixedly connected to the outer wall of the filter frame. A slide rail is slidably connected to the outer wall of the slider, and the slide rail is fixedly installed on the inner wall of the disinfection tank.

[0009] Preferably, the filter frame is integrated into a lifting structure by means of connecting rods, hooks and pull rods. There are four sliders, and the outer walls of the four sliders are slidably connected to slide rails. The shape and size of the outer walls of the sliders and the inner walls of the slide rails are matched.

[0010] Preferably, the inner wall of the disinfection tank is provided with disinfection lamps, and there are eight disinfection lamps, which are arranged at equal intervals on the inner wall of the disinfection tank.

[0011] Preferably, the first bevel gear forms a rotating structure with the motor via a transmission rod, and the fixed rod forms an integrated rotating structure with the first bevel gear via a second bevel gear, with a sterilization tank connected to the outer wall bearing of the fixed rod.

[0012] Preferably, the stirring rod forms a circular motion with the fixed rod via a stirrer, and a stirring blade is fixedly connected to the outer wall of the stirring rod, and the stirring blade is arc-shaped.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the disinfection device for waste liquid treatment;

[0014] 1. The device is equipped with a disinfection lamp, a stirrer, and a stirring rod. A motor drives a transmission rod and a first bevel gear to rotate. At the same time, a fixed rod rotates along with the first bevel gear via a second bevel gear. This causes the stirrer to drive the push plate and the stirring rod to move in a circular motion. The stirring rod then drives the stirring blades to guide the flow of waste liquid, thereby ensuring the uniformity of the mixing between the waste liquid and the disinfectant. This reduces the survival rate of pathogens in the waste liquid and ensures that the waste liquid comes into full contact with the ultraviolet light generated by the disinfection lamp. This ensures the stability of the overall device in disinfecting waste liquid and increases the practicality of the overall device.

[0015] 2. The filter frame is raised and lowered using a combination of a cap, filter frame, and slide rail. The cap, along with a hook and connecting rod, moves the filter frame up and down. The filter frame slides along the slide rail via a slider, allowing it to be reset and installed. The filter frame effectively removes suspended solids, particulate matter, and large organic molecules from the waste liquid, preventing these substances from blocking ultraviolet light and ensuring the disinfection effect of the subsequent disinfection lamp. It also facilitates easy disassembly and assembly of the filter frame, allowing for subsequent cleaning of impurities and ensuring the effective filtration of the waste liquid.

Detailed Implementation

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0022] Please see Figure 1-2 This utility model provides a technical solution: a disinfection device for waste liquid treatment, including a disinfection tank 1, a cover 2 installed on the top of the disinfection tank 1, and an inlet pipe 3 installed through the inner wall of the cover 2. A pull rod 4 is fixedly connected to the top of the cover 2, and the cover 2 forms a tension structure through the pull rod 4. A hook 5 is engaged with the bottom of the cover 2, and a connecting rod 6 is fixedly connected to the other end of the hook 5. The pull rod 4 facilitates the simultaneous removal of the filter frame 7 when the cover 2 is removed, so as to facilitate the replacement of the filter frame 7. The filter frame 7 is fixedly connected to the other end of the connecting rod 6. A slider 8 is fixedly connected to the outer wall, and a slide rail 9 is slidably connected to the outer wall of the slider 8. The slide rail 9 is fixedly installed on the inner wall of the disinfection tank 1. The slide rail 9 ensures the stability of the filter frame 7 when it is taken out. The filter frame 7 forms an integrated lifting structure with the connecting rod 6, hook 5 and pull rod 4. There are four sliders 8, and the outer walls of the four sliders 8 are slidably connected to the slide rail 9. The shape and size of the outer wall of the slider 8 and the inner wall of the slide rail 9 match each other. The sliders 8 further prevent the filter frame 7 from shaking when it is taken out, so as to prevent foreign objects from falling. A conveying pipe 10 is installed through the outer wall of the disinfection tank 1.

[0023] The specific implementation method is as follows: Through the set cover 2, filter frame 7 and slide rail 9, the cover 2, together with the hook 5 and connecting rod 6, raises and lowers the filter frame 7. At this time, the filter frame 7 slides along the slide rail 9 through the slider 8, so that the filter frame 7 is reset and installed. The filter frame 7 can effectively remove suspended solids, particulate matter and large molecular organic matter in the waste liquid, prevent these substances from blocking the ultraviolet rays, ensure the disinfection effect of the subsequent disinfection lamp 11 on the waste liquid, and facilitate the disassembly and assembly of the filter frame 7 by the staff, so that the staff can clean the impurities in the filter frame 7, and ensure the filtration effect of the filter frame 7 on the waste liquid.

[0024] Please see Figure 1-4This utility model provides a technical solution: a disinfection device for waste liquid treatment. The inner wall of a disinfection tank 1 is equipped with eight disinfection lamps 11, which are equidistantly arranged on the inner wall of the tank. The ultraviolet light generated by the disinfection lamps 11 treats pathogens in the waste liquid. A motor 12 is fixedly connected to the bottom of the disinfection tank 1, and the output shaft of the motor 12 is connected to a transmission rod 13 via a coupling. A first bevel gear 14 is fixedly connected to the outer wall of the transmission rod 13, and a second bevel gear 15 is meshed with the outer wall of the first bevel gear 14. A fixing rod 16 is fixedly connected to the inner wall of the second bevel gear 15, and a stirrer 17 is fixedly connected to the outer wall of the fixing rod 16. The first bevel gear 14 and the motor 12 form a rotating structure through the transmission rod 13. The fixed rod 16 forms an integrated rotating structure with the first bevel gear 14 via the second bevel gear 15. The outer wall of the fixed rod 16 is connected to the disinfection tank 1 via a bearing. The second bevel gear 15 enables the fixed rod 16 to rotate and drive the stirrer 17 to mix the waste liquid and disinfectant. A push plate 18 is installed on one side of the stirrer 17, and a stirring rod 19 is fixedly connected to the top of the stirrer 17. The stirring rod 19 forms a circular motion with the fixed rod 16 via the stirrer 17. A stirring blade 20 is fixedly connected to the outer wall of the stirring rod 19. The stirring blade 20 is arc-shaped and guides the flow of waste liquid, further ensuring the uniformity of mixing of waste liquid and disinfectant. A drain pipe 21 is installed through the outer wall of the disinfection tank 1.

[0025] The specific implementation method is as follows: Using a disinfection lamp 11, a stirrer 17, and a stirring rod 19, a motor 12 drives a transmission rod 13 and a first bevel gear 14 to rotate. At this time, a fixed rod 16 rotates along with the first bevel gear 14 via a second bevel gear 15. This causes the stirrer 17 to drive a push plate 18 and a stirring rod 19 in a circular motion. The stirring rod 19 then drives the stirring blades 20 to guide the waste liquid flow, ensuring the uniformity of the mixture between the waste liquid and the disinfectant, reducing the survival rate of pathogens in the waste liquid, and simultaneously ensuring sufficient contact between the waste liquid and the ultraviolet light generated by the disinfection lamp 11. This ensures the stability of the overall device in disinfecting the waste liquid and increases the practicality of the entire device.

[0026] Working principle: When using this disinfection device for waste liquid treatment, first connect the inlet pipe 3 to the waste liquid discharge pipe. At this time, the waste liquid is transported to the disinfection tank 1 through the inlet pipe 3, so that the waste liquid falls to the inner bottom wall of the disinfection tank 1 through the filter frame 7, thereby filtering the waste liquid through the filter frame 7, thereby reducing the hiding place of microorganisms, so that the ultraviolet rays generated by the disinfection lamp 11 can act on microorganisms more directly and improve the sterilization efficiency. At the same time, the delivery pipe 10 delivers the disinfectant to the disinfection tank 1. At this time, the motor 12 is started, so that the motor 12 drives the transmission rod 13 to rotate, thereby driving the first bevel gear 14 to rotate through the transmission rod 13.

[0027] Since the outer wall of the first bevel gear 14 is meshed with the second bevel gear 15, the first bevel gear 14 drives the second bevel gear 15 to rotate. At this time, the second bevel gear 15 drives the stirrer 17 to rotate at an angle through the fixed rod 16, so that the stirrer 17 drives the three push plates 18 to mix the waste liquid. At the same time, the stirring rod 19 rotates synchronously through the stirrer 17, thereby driving the stirring blade 20 to guide the flow of waste liquid, thus ensuring the uniformity of the mixing of waste liquid and disinfectant, so that the waste liquid can fully contact the ultraviolet rays generated by the disinfection lamp 11, improving the disinfection effect of the disinfection lamp 11 on the waste liquid.

[0028] After disinfection is completed, pull rod 4 is pulled to detach the cover 2 from the disinfection tank 1. Since the cover 2 is engaged with the hook 5, the cover 2 pulls the filter frame 7 through the hook 5 and the connecting rod 6, so that the filter frame 7 slides along the slide rail 9 fixed on the inner wall of the disinfection tank 1 via the slider 8. This makes it easy for staff to remove the filter frame 7, so that they can clean the impurities in the filter frame 7 later, ensuring the filter frame 7 can effectively filter the waste liquid.

[0029] 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.
