[0001] This utility model belongs to the field of sedimentation tank technology, and specifically relates to a sewage treatment sedimentation tank with a sludge scraping structure. Background Technology

[0002] Wastewater treatment is the prevention and control of environmental pollution. It is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields and is increasingly entering the daily lives of ordinary people. A wastewater sedimentation tank is a device used to remove suspended solids and sediments from wastewater. It uses the principle of gravity sedimentation to settle solid particles in wastewater to the bottom of the tank, thereby achieving the initial treatment of wastewater.

[0003] In common wastewater treatment sedimentation tanks, solid particles in wastewater settle to the bottom of the tank, resulting in the accumulation of sludge and impurities. The inner walls of the sedimentation tank are also covered with sludge and impurities. Cleaning these sludge and impurities is a tedious and time-consuming process, which affects the efficiency of subsequent work.

[0004] Therefore, a wastewater treatment sedimentation tank with a sludge scraping structure is designed to solve the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a wastewater treatment sedimentation tank equipped with a sludge scraping structure. Under centrifugal force, the cleaning plate and telescopic rod stretch the spring inside the cleaning arm, causing them to extend outwards. Simultaneously, the inclined cleaning arm further increases the centrifugal force of the telescopic rod, increasing the cleaning force on the inner wall of the sedimentation tank. This allows for the cleaning of firmly fixed impurities, increasing cleaning efficiency. Furthermore, the cleaning plate has a certain inclination angle, causing impurities on the inner wall of the sedimentation tank to fall downwards during scraping, rather than accumulating upwards along the plate, thus increasing the practicality of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sewage treatment sedimentation tank with a sludge scraping structure, comprising a sedimentation tank body and a scraping component disposed at the end of the sedimentation tank body;

[0007] The scraping assembly includes a top cover, a protective cover, and a motor. The top cover is fixedly connected to the outer side of the end of the sedimentation tank body, and the protective cover is fixedly connected to the outer side of the end of the top cover. The motor is mounted on the upper surface of the protective cover, and a first gear is fixedly connected to the outer side of the main shaft of the motor. A second gear is rotatably connected to the outer side of the center position of the top cover. The first gear and the second gear are meshed together. A rotating shaft is fixedly connected to the outer side of one end of the second gear. Several cleaning arms are fixedly connected to the outer side of the end of the rotating shaft in a ring. A cleaning plate is provided on the outer side of the end of each cleaning arm, and the cleaning plate is in contact with the inner wall surface of the sedimentation tank body.

[0008] As a preferred embodiment of the wastewater treatment sedimentation tank with a sludge scraping structure of this utility model, a telescopic rod is slidably connected to the inner side of the end of the cleaning arm, the outer sides of both ends of the spring are fixedly connected to the inner side of the end of the cleaning arm and the outer side of one end of the telescopic rod, respectively, the outer side of the end of the telescopic rod is rotatably connected to the cleaning plate, and the cleaning plate has a certain tilt angle.

[0009] As a preferred embodiment of the wastewater treatment sedimentation tank with a sludge scraping structure of the present invention, a rubber strip is fixedly connected to the outer side of the end of the cleaning plate, and the rubber strip is made of rubber.

[0010] As a preferred embodiment of the wastewater treatment sedimentation tank with a sludge scraping structure of the present invention, a spiral blade is fixedly connected to the outer side of the end of the rotating shaft.

[0011] As a preferred embodiment of the wastewater treatment sedimentation tank with a sludge scraping structure of the present invention, a conical barrel is provided on the outer side of the end of the sedimentation tank body, and the conical barrel has a conical structure.

[0012] As a preferred embodiment of the wastewater treatment sedimentation tank with a sludge scraping structure of the present invention, the outer side of the end of the upper cover is fixedly connected with several lifting rings in a ring.

[0013] As a preferred embodiment of the wastewater treatment sedimentation tank with a sludge scraping structure of the present invention, the outer end of the sedimentation tank body is detachably connected with a plug plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The addition of a scraping component in this application allows the cleaning plate and telescopic rod to stretch the spring inside the cleaning arm under centrifugal force, thereby extending the cleaning plate and telescopic rod outwards. Simultaneously, the inclined cleaning arm further increases the centrifugal force of the telescopic rod, increasing the cleaning force on the inner wall of the sedimentation tank. This allows for the cleaning of some firmly fixed impurities, increasing cleaning efficiency. Furthermore, the cleaning plate has a certain inclination angle, so when scraping the inner wall of the sedimentation tank, the impurities on the inner wall will fall downwards under the action of the cleaning plate, rather than accumulating upwards along the cleaning plate, increasing the practicality of the device.

[0023] 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.

[0024] like Figure 1 As shown;

[0025] A wastewater treatment sedimentation tank with a sludge scraping structure includes a sedimentation tank body 1.

[0026] In this implementation plan: Wastewater treatment is the prevention and control of environmental pollution. It is a process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields and is increasingly entering the daily lives of ordinary people. A wastewater treatment sedimentation tank is a device used to remove suspended solids and sediments from wastewater. It uses the principle of gravity sedimentation to settle solid particles in wastewater to the bottom of the tank, thereby achieving preliminary treatment of wastewater. In common wastewater treatment sedimentation tanks, after the solid particles in the wastewater settle to the bottom of the tank, sludge and impurities will accumulate at the bottom of the sedimentation tank, and sludge and impurities will adhere to the inner wall of the sedimentation tank. When cleaning sludge and impurities, the cleaning work of the staff is relatively cumbersome and time-consuming, which affects the efficiency of subsequent work. To solve this technical problem, a scraping component 2 is added to this basis.

[0027] Furthermore:

[0028] like Figures 1 to 4 As shown:

[0029] Based on the above: the scraping assembly 2 includes a top cover 21, a protective cover 22, and a motor 23. The top cover 21 is fixedly connected to the outer side of the end of the sedimentation tank body 1. The protective cover 22 is fixedly connected to the outer side of the end of the top cover 21. The motor 23 is mounted on the upper surface of the protective cover 22. A first gear 24 is fixedly connected to the outer side of the main shaft of the motor 23. A second gear 25 is rotatably connected to the outer side of the center position of the top cover 21. The first gear 24 and the second gear 25 are meshed. A rotating shaft 26 is fixedly connected to the outer side of one end of the second gear 25. The end of the rotating shaft 26... Several cleaning arms 27 are fixedly connected to the outer ring. A cleaning plate 28 is provided on the outer side of the end of the cleaning arm 27. The cleaning plate 28 is in contact with the inner wall of the sedimentation tank body 1. A telescopic rod 29 is slidably connected to the inner side of the end of the cleaning arm 27. The outer sides of both ends of the spring 210 are fixedly connected to the inner side of the end of the cleaning arm 27 and the outer side of one end of the telescopic rod 29, respectively. The outer side of the end of the telescopic rod 29 is rotatably connected to the cleaning plate 28. The cleaning plate 28 has a certain tilt angle. A plug plate 215 is detachably connected to the outer side of the end of the sedimentation tank body 1.

[0030] In this implementation scheme: In this device, the interior of the sedimentation tank body 1 is a hollow barrel-shaped structure for wastewater sedimentation. A top cover 21 is fixedly connected to the outer side of the opening end of the sedimentation tank body 1, and a protective cover 22 is fixedly connected to the outer side of the end of the top cover 21. When the user needs to clean the sedimentation tank, simply start the motor 23. The motor 23 drives the first gear 24 to rotate, which in turn drives the second gear 25, which meshes with the first gear 24, to rotate. The second gear 25 drives the rotating shaft 26 on the outer side of its end to rotate. The cleaning arm 27 has an L-shaped structure, and one end of the cleaning arm 27 has a certain angle of inclination. At the same time, the interior of the cleaning arm 27 is connected to a telescopic rod 29 by a spring 210. A cleaning plate 28 is rotatably connected to the outer side of the end of the telescopic rod 29. The cleaning plate 28 is in close contact with the inner wall surface. When the rotating shaft 26 drives several cleaning arms 27 to rotate, it will drive the outer side of the end of the telescopic rod 29 to clean. Plate 28 continuously scrapes the inner wall of the sedimentation tank body 1, cleaning impurities from the inner wall. Simultaneously, when the user increases the rotation speed of motor 23, the rotation speed of cleaning arm 27 on the outer side of shaft 26 also increases. Under centrifugal force, cleaning plate 28 and telescopic rod 29 stretch the spring 210 inside cleaning arm 27, causing them to extend outwards. The inclined cleaning arm 27 further increases the centrifugal force of telescopic rod 29, increasing the cleaning force on the inner wall of sedimentation tank body 1. This allows for the cleaning of firmly fixed impurities, increasing cleaning efficiency. Furthermore, the cleaning plate 28 has a certain inclination angle, causing impurities to fall downwards during scraping, rather than accumulating upwards along the cleaning plate 28, thus increasing the device's practicality.

[0031] Furthermore:

[0032] In an optional embodiment, an adhesive strip 211 is fixedly connected to the outer end of the cleaning plate 28, and the adhesive strip 211 is made of rubber.

[0033] In this embodiment: A rubber strip 211 is fixedly connected to the outer side of the end of the cleaning plate 28. The rubber strip 211 is made of hard rubber. When the cleaning plate 28 cleans the inner wall of the sedimentation tank body 1, the rubber strip 211 will not scratch the inner wall of the sedimentation tank body 1. At the same time, the rubber material of the rubber strip 211 can increase the friction on the inner wall of the sedimentation tank body 1, thereby increasing the cleaning effect on the inner wall of the sedimentation tank body 1.

[0034] Furthermore:

[0035] In an optional embodiment, a spiral blade 212 is fixedly connected to the outer end of the rotating shaft 26, and an insert plate 215 is detachably connected to the outer end of the sedimentation tank body 1.

[0036] In this embodiment: a spiral blade 212 is fixedly connected to the outer side of the end of the rotating shaft 26. The spiral blade 212 has a spiral structure. When the rotating shaft 26 rotates, it will drive the spiral blade 212 on the outer side of the rotating shaft 26 to rotate at the same time. Meanwhile, the conical barrel 213 on the outer side of the end of the sedimentation tank body 1 has a conical structure. Impurities fall from the inner wall of the sedimentation tank body 1 and flow downward through the conical barrel 213, and then are transported outward through the spiral blade 212. At the same time, the rotation of the spiral blade 212 can form a vortex inside the sedimentation tank body 1, which increases the discharge efficiency of impurities. The insert plate 215 on the outer side of the end of the sedimentation tank body 1 can block the conical barrel 213. When it is necessary to discharge impurities, the insert plate 215 can be removed.

[0037] Furthermore:

[0038] In an optional embodiment, a plurality of lifting rings 214 are fixedly connected to the outer side of the end of the top cover 21 in a ring.

[0039] In this implementation scheme, several lifting rings 214 are fixedly connected to the outer side of the end of the top cover 21 in a ring shape. Workers can connect the lifting rings 214 with a crane to lift the device, which can be used for maintenance and upkeep, thus increasing the practicality of the device.

[0040] Working principle: In this device, the interior of the sedimentation tank body 1 is a hollow barrel-shaped structure for wastewater sedimentation. A top cover 21 is fixedly connected to the outer side of the opening of the sedimentation tank body 1, and a protective cover 22 is fixedly connected to the outer side of the top cover 21. When the user needs to clean the sedimentation tank, simply start the motor 23. The motor 23 drives the first gear 24 to rotate, which in turn drives the second gear 25, which meshes with the first gear 24, to rotate. The second gear 25 drives the rotating shaft 26 on its outer side to rotate. The cleaning arm 27 has an L-shaped structure, and one end of the cleaning arm 27 has a certain angle of inclination. Simultaneously, a telescopic rod 29 is connected inside the cleaning arm 27 via a spring 210. A cleaning plate 28 is rotatably connected to the outer side of the end of the telescopic rod 29. The cleaning plate 28 is tightly... When the rotating shaft 26 drives several cleaning arms 27 to rotate, it will cause the outer cleaning plate 28 at the end of the telescopic rod 29 to continuously scrape the inner wall of the sedimentation tank body 1, which can clean the impurities on the inner wall of the sedimentation tank body 1. At the same time, when the user increases the rotation speed of the motor 23, it will also increase the rotation speed of the outer cleaning arm 27 of the rotating shaft 26. Under the action of centrifugal force, the cleaning plate 28 and the telescopic rod 29 will stretch the spring 210 inside the cleaning arm 27, thereby causing the cleaning plate 28 and the telescopic rod 29 to extend outward. At the same time, the inclined structure of the cleaning arm 27 can further increase the centrifugal force of the telescopic rod 29, increase the cleaning force on the inner wall of the sedimentation tank body 1, and can clean some more firmly fixed impurities, increasing the cleaning efficiency. The cleaning plate 28 has a certain tilt angle. When scraping the inner wall of the sedimentation tank body 1, the impurities on the inner wall of the sedimentation tank body 1 will fall downwards under the action of the cleaning plate 28, instead of accumulating upwards along the cleaning plate 28, which increases the practicality of the device. A rubber strip 211 is fixedly connected to the outer end of the cleaning plate 28. The rubber strip 211 is made of hard rubber. When the cleaning plate 28 cleans the inner wall of the sedimentation tank body 1, the rubber strip 211 will not scratch the inner wall of the sedimentation tank body 1. At the same time, the rubber material of the rubber strip 211 can increase the friction on the inner wall of the sedimentation tank body 1, which increases the cleaning effect on the inner wall of the sedimentation tank body 1. A spiral blade 212 is fixedly connected to the outer end of the rotating shaft 26. The spiral blade 212 has a spiral structure. When the rotating shaft 26 rotates, This will simultaneously drive the spiral blades 212 on the outer side of the rotating shaft 26 to rotate. Meanwhile, the conical barrel 213 on the outer side of the sedimentation tank body 1 has a conical structure. Impurities falling from the inner wall of the sedimentation tank body 1 will flow downwards through the conical barrel 213 and then be conveyed outwards by the spiral blades 212. Simultaneously, the rotation of the spiral blades 212 can create a vortex inside the sedimentation tank body 1, increasing the efficiency of impurity discharge. The insert plate 215 on the outer side of the sedimentation tank body 1 can block the conical barrel 213. When it is necessary to discharge impurities, the insert plate 215 can be removed. Several lifting rings 214 are fixedly connected to the outer side of the end of the top cover 21 in a ring. Workers can connect the lifting rings 214 using a crane to lift the device for maintenance and upkeep.This increases the practicality of the device.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
