Description

Technical Field

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

[0002] Wastewater treatment refers to the process of removing or transforming harmful substances in wastewater through physical, chemical, and biological methods to meet discharge standards or reuse water quality requirements. During wastewater treatment, disinfection tanks are typically used to further purify the wastewater and ensure it meets discharge or reuse standards. Disinfection tanks are an important component of wastewater treatment systems, used to disinfect pre-treated wastewater to kill pathogenic microorganisms (such as bacteria, viruses, and parasites). By killing harmful microorganisms through chemical or physical means, disinfection tanks reduce the risk of disease transmission. Furthermore, treatment in disinfection tanks significantly reduces the concentration of harmful substances in wastewater, thereby protecting aquatic ecosystems.

[0003] When treating wastewater through a disinfection tank, the wastewater enters the tank, and disinfectant is usually added. The disinfectant and wastewater are then stirred to achieve a mixing reaction, thereby disinfecting the wastewater. However, existing stirring methods are relatively simple. The stirring mechanism usually mixes the disinfectant and wastewater in a fixed position, which limits the stirring area and range. Furthermore, the wastewater flow pattern is monotonous, which cannot ensure sufficient contact between the disinfectant and wastewater. This is not conducive to eliminating mixing dead zones and improving disinfection quality. Therefore, to solve the above problems, a disinfection tank for wastewater treatment is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a disinfection tank for sewage treatment, in order to solve the problem mentioned in the background art that the existing stirring methods are relatively simple. The stirring mechanism usually mixes the disinfectant and sewage in a fixed position, which limits the stirring area and range and the sewage flow pattern. As a result, it cannot ensure sufficient contact between the disinfectant and the sewage, thus failing to eliminate mixing dead zones and improve disinfection quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a disinfection tank for sewage treatment, comprising a disinfection box, a sewage tank fixedly connected to one side of the disinfection box, a drain pipe fixedly connected to the surface of the disinfection box, a stirring shaft provided inside the disinfection box, a stirring rod fixedly connected to the surface of the stirring shaft, a first motor provided at the top of the stirring shaft, and the output end of the stirring shaft and the first motor fixedly connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The rotation of the reciprocating screw enables the first moving block to move the connecting frame left and right, thereby enabling the reciprocating movement of the stirring shaft and stirring rod. The rotation of the forward and reverse screws enables the second moving block to move the stirring shaft and stirring rod in opposite directions. Thus, the stirring shaft and stirring rod can move left and right and forward and backward simultaneously during rotation, which expands the mixing range and allows the wastewater to come into better contact with the disinfectant, improving the thoroughness of mixing.

[0020] 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.

[0021] Please see Figure 1-4 One embodiment provided by this utility model:

[0022] The first motor 15, the second motor 22, and the third motor 26 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, and therefore will not be described in detail here.

[0023] A disinfection tank for sewage treatment includes a disinfection tank 1. A sewage tank 11 is fixedly connected to one side of the disinfection tank 1. A drain pipe 12 is fixedly connected to the surface of the disinfection tank 1. A stirring shaft 13 is provided inside the disinfection tank 1. A stirring rod 14 is fixedly connected to the surface of the stirring shaft 13. A first motor 15 is provided at the top of the stirring shaft 13. The output end of the stirring shaft 13 and the first motor 15 are fixedly connected. By adding disinfectant into the disinfection tank 1, the stirring shaft 13 and the stirring rod 14 are rotated in conjunction with the operation of the first motor 15. The stirring rod 14 can be used to stir the sewage and disinfectant, thereby achieving a mixing reaction between the two and facilitating disinfection.

[0024] The surface of the disinfection box 1 is provided with a moving mechanism, which includes a support frame 2. The support frame 2 is fixedly connected to the upper surface of the disinfection box 1. A reciprocating screw 21 is movably connected to the inner side of the support frame 2. A second motor 22 is fixedly installed on the surface of the support frame 2. A first moving block 23 is movably connected to the surface of the reciprocating screw 21. A connecting frame 24 is fixedly connected to the bottom end of the first moving block 23. A positive and negative screw 25 is movably connected to the inner side of the connecting frame 24. A third motor 26 is fixedly installed on the surface of the connecting frame 24. A second moving block 27 is threadedly connected to the surface of the positive and negative screw 25. By rotating the reciprocating screw 21, the first moving block 23 can drive the connecting frame 24 to move. As a result, the stirring shaft 13 and the stirring rod 14 can reciprocate left and right during rotation, which facilitates the expansion of the stirring range and allows the sewage and disinfectant to be better and more fully mixed, which is beneficial to improving the disinfection quality.

[0025] Furthermore, the moving mechanism also includes a limiting groove 28, which is opened inside the connecting frame 24. The second moving block 27 is movable inside the limiting groove 28. A limiting rod 29 is fixedly connected to the upper surface of the disinfection box 1. The connecting frame 24 and the limiting rod 29 are movably connected. By opening the limiting groove 28 and setting the limiting rod 29, the second moving block 27 and the connecting frame 24 can be limited, thereby preventing the connecting frame 24 and the second moving block 27 from shifting, which facilitates the stable movement of the stirring shaft 13 and the stirring rod 14.

[0026] Furthermore, the output ends of the reciprocating screw 21 and the second motor 22 are fixedly connected, and the output ends of the positive and negative screws 25 and the third motor 26 are fixedly connected. The second moving block 27 is connected in two groups to the positive and negative screws 25. The first motor 15 is fixedly installed inside the second moving block 27, and the stirring shaft 13 moves inside the second moving block 27. By rotating the positive and negative screws 25, the second moving block 27 can drive the stirring shaft 13 and the stirring rod 14 to move back and forth in opposite directions. The stirring forces in different directions are superimposed, which can better avoid stirring dead zones, and thus improve the mixing and reaction effect of sewage and disinfectant.

[0027] Furthermore, a filtration mechanism is provided inside the sewage tank 11. The filtration mechanism includes a support frame 3, which is fixedly connected to the inner wall of the sewage tank 11. A filter plate 31 is provided inside the sewage tank 11. A connecting plate 32 is fixedly connected to the upper surface of the filter plate 31. A fixing rod 33 is fixedly connected to the surface of the sewage tank 11. A movable plate 34 is movably connected to the surface of the fixing rod 33. An insert block 35 is fixedly connected to the surface of the movable plate 34. A through groove 36 is opened inside the connecting plate 32. A spring 37 is fixedly connected to the surface of the insert block 35. By moving the movable plate 34 on the surface of the fixing rod 33, and with the elasticity of the spring 37, the insert block 35 can be inserted into and separated from the through groove 36. This facilitates the fixing and unfixing of the connecting plate 32, and makes it easy to remove the filter plate 31 for cleaning or replacement, so as to ensure the filtration effect of sewage.

[0028] Furthermore, the filter plate 31 is attached to the support frame 3, the insert blocks 35 are fixedly connected to the movable plate 34 in two groups, and the through grooves 36 are opened in two groups on the inner side of the connecting plate 32. The filter plate 31 can be supported by the support frame 3. The filter plate 31 can intercept impurities and particles in the sewage, thus achieving filtration.

[0029] Furthermore, one end of the spring 37 is fixedly connected to the sewage tank 11, and the other end of the spring 37 is fixedly connected to the movable plate 34. By setting the spring 37, the movable plate 34 can be reset, which facilitates the insertion block 35 to be reset and inserted into the through slot 36, thereby enabling the fixing of the connecting plate 32.

[0030] Working principle: In use, the second motor 22 is electrically connected to an external power source. The operator starts the second motor 22 by pressing the switch. The second motor 22 drives the reciprocating screw 21 to rotate. The connecting frame 24 is limited by the limiting rod 29, so that the first moving block 23 moves back and forth under the action of the reciprocating screw 21, thereby realizing the movement of the connecting frame 24. This also enables the stirring shaft 13 to drive the stirring rod 14 to reciprocate left and right while rotating. The third motor 26 is electrically connected to an external power source. The operator starts the third motor 26 by pressing the switch. The third motor 26 drives the forward and reverse screws 25 to rotate. The second moving block 27 is limited by the limiting groove 28 and will move back and forth in opposite directions under the action of the forward and reverse screws 25, and move within the limiting groove 28. Then, the third motor 26 drives the forward and reverse screws 25 to rotate forward and reverse, so that the stirring shaft 13 can drive the stirring rods 14 to move closer or further apart during rotation, thereby expanding the stirring area and range.

[0031] The filter plate 31 is designed to intercept impurities and particles in wastewater, thus achieving filtration. When the filter plate 31 needs to be cleaned or replaced, the movable plate 34 is pushed, allowing it to move on the surface of the fixed rod 33. At this time, the spring 37 is in a contracted state, and the insert block 35 moves accordingly and separates from the through groove 36, thereby releasing the restriction on the connecting plate 32. Then, the connecting plate 32 is pulled to remove the filter plate 31 from the wastewater tank 11. When the filter plate 31 needs to be fixed, the filter plate 31 is placed in the wastewater tank 11 and overlapped on the support frame 3. Then, the movable plate 34 is released, and the movable plate 34 will return to its original position under the rebound of the spring 37, allowing the insert block 35 to return to its original position and engage with the through groove 36, thereby limiting the connection plate 32 and fixing the filter plate 31.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
