Description

Technical Field

[0001] This utility model relates to the field of sewage sludge discharge technology, and in particular to a sludge discharge device for sewage treatment. Background Technology

[0002] A search of existing technology (CN222900306U) reveals a sludge removal device for sewage treatment, belonging to the field of sewage treatment sludge removal technology. This device includes a sewage treatment tank, on the surface of which is provided a rotating assembly. The rotating assembly includes an annular slide rail, two sliders, a connecting plate, a through hole, multiple connecting rods, and a spiral push plate. A transmission assembly is provided on the surface of the connecting plate, including a rotating shaft, gears, a gear ring, and a motor.

[0003] The gear assembly in this technology is exposed above the sewage treatment tank for a long time, making it highly susceptible to corrosion due to the humid and corrosive environment. Frequent rust removal and protective maintenance are required, which not only increases the difficulty of equipment maintenance but also significantly increases the operating cost. In addition, when there is too much sludge accumulation, it is difficult to pump the thick sludge to the outside by using only a vacuum pump and pipeline. Utility Model Content

[0004] The main objective of this invention is to provide a sludge removal device for wastewater treatment, which aims to solve the problems mentioned in the background art.

[0005] To address the aforementioned problems, this utility model proposes a sludge removal device for wastewater treatment, comprising a wastewater treatment tank. A cleaning component is installed on the upper part of the inner wall of the wastewater treatment tank. The cavity of the wastewater treatment tank gradually narrows and its diameter gradually decreases towards the lower part. A guide pipe is fixedly installed at the center of the bottom surface of the cavity. An auger is rotatably installed on the inner wall of the guide pipe. A guide box is fixedly installed at the top of the guide pipe. A first motor is fixedly installed at the center of the top of the guide box. The output end of the first motor passes through the guide box and is rotatably connected to the top of the auger.

[0006] In one embodiment, a discharge pipe is fixedly installed at the discharge port on one side of the flow guide box, and a vacuum pump is fixedly installed on a section of the discharge pipe.

[0007] In one embodiment, a fixing frame is fixedly installed around the top surface of the sewage treatment tank, and the top of each fixing frame is fixedly connected to the four corners of the diversion box.

[0008] In one embodiment, a second motor is fixedly installed on the top surface of the sewage treatment tank, near one of the fixing frames.

[0009] In one embodiment, the cleaning component includes a first gear, with scrapers fixedly spaced on the inner wall of the first gear, guide grooves at both the upper and lower ends of the circumference of the first gear, and a second gear meshing with one side of the first gear.

[0010] In one embodiment, the output end of the second motor is connected to the center of the top surface of the second gear.

[0011] Beneficial effects:

[0012] 1. This device significantly improves the efficiency of sludge collection by gradually tightening the bottom of the sewage treatment tank to form a slope, allowing the sludge to naturally accumulate at the bottom of the tank, facilitating subsequent cleaning and discharge. At the same time, the cleaning components are installed in a dedicated rotating chamber and protected by lubricating grease, which can effectively prevent rust and corrosion problems caused by long-term use, greatly extending the service life of the equipment and reducing maintenance costs.

[0013] 2. The scraper in this cleaning component is in close contact with the inner wall of the treatment tank. Driven by the gear structure, it can move circumferentially along the tank wall, effectively cleaning and breaking up the sludge in the sewage treatment tank and concentrating it at the bottom of the tank. The collected sludge is transported to the diversion pipe through the auger, and then guided into the reflux box by the diversion pipe. Through the cooperation of the discharge pipe and the vacuum pump, the sludge is successfully discharged to the outside for collection and further treatment. Attached Figure Description

[0022] 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.

[0023] To achieve the above-mentioned utility model objectives, such as Figure 1-4 As shown, this utility model provides a sludge removal device for sewage treatment, including a sewage treatment tank 1. A cleaning component 7 is installed on the upper part of the inner wall of the sewage treatment tank 1. The cavity of the sewage treatment tank 1 gradually tightens and the diameter gradually decreases at the lower part. A guide pipe 9 is fixedly installed at the center of the bottom surface of the cavity. An auger 8 is rotatably installed on the inner wall of the guide pipe 9. A guide box 2 is fixedly installed at the top of the guide pipe 9. A first motor 3 is fixedly installed at the center of the top of the guide box 2. The output end of the first motor 3 passes through the guide box 2 and is rotatably connected to the top of the auger 8. A discharge pipe 5 is fixedly installed at the discharge port on one side of the guide box 2. A vacuum pump 4 is fixedly installed on a section of the discharge pipe 5. Fixing frames 10 are fixedly installed around the top surface of the sewage treatment tank 1. The tops of the fixing frames 10 are all fixedly connected to the four corners of the guide box 2. A second motor 6 is fixedly installed on the top surface of the sewage treatment tank 1, near one of the fixing frames 10.

[0024] Specifically, wastewater treatment tank 1, serving as the foundation structure of the entire sludge removal equipment, features a gradually tapering inner wall design, forming a conical structure. This design facilitates the collection and aggregation of sludge from the wastewater towards the bottom of the tank, thereby simplifying subsequent cleaning and discharge and ensuring high efficiency in the treatment process.

[0025] The cleaning component 7 is located on the upper part of the inner wall of the sewage treatment tank 1. It rotates to clean the dirt and accumulated sludge on the inner wall, effectively keeping the tank wall clean and preventing dirt buildup. It also scrapes dirt and sludge to the bottom of the tank, facilitating discharge through the guide pipe 9 and ensuring smooth system operation. The guide pipe 9 is located at the center of the bottom of the sewage treatment tank 1 and is mainly used to guide and collect the sludge accumulated at the bottom. The inner wall of the guide pipe 9 is equipped with an auger 8. Under the rotation of the auger 8, the sludge is effectively transported to the guide box 2. The auger 8 not only transports the sludge but also effectively stirs and clears it, ensuring smooth flow of the sludge into the guide box 2.

[0026] The auger 8 is rotated and installed on the inner wall of the guide pipe 9. Driven by the first motor 3, the auger 8 drives the sludge gathered at the bottom of the pool to be transported to the guide box 2 along the guide pipe 9. The operation of the auger 8 realizes the transportation, dredging and stirring of the sludge, ensuring that the sludge can flow into the guide box 2 efficiently.

[0027] The diversion box 2 is installed on the top of the diversion pipe 9 to receive the sludge transported from the diversion pipe 9. The diversion box 2 is reasonably designed to ensure that the sludge gathers here and is ready for subsequent discharge. The first motor 3 is fixedly installed on the top of the diversion box 2 to provide power support for the entire sludge discharge process.

[0028] The first motor 3 is located at the top center of the guide box 2 and is responsible for driving the rotation of the auger 8. The power drive of the motor ensures that the auger 8 can efficiently transport the sludge from the guide pipe 9 to the guide box 2, completing the entire sludge discharge process.

[0029] The discharge pipe 5 is connected to the discharge port on one side of the diversion box 2. It is responsible for transporting the collected sludge to the external treatment system or storage container through the pipeline. The discharge pipe 5 is the main channel of the entire sludge discharge system.

[0030] Vacuum pump 4 is installed on a section of the discharge pipe 5 and is responsible for providing negative pressure. Through the negative pressure, vacuum pump 4 helps to smoothly draw sludge into discharge pipe 5 and efficiently discharge it to the outside, improving sludge discharge efficiency and ensuring that sludge can flow out stably.

[0031] The fixing frame 10 is installed around the top surface of the sewage treatment tank 1 to provide support and fixation for the entire equipment. The fixing frame 10 ensures the stable installation of the diversion box 2 and other components, and maintains the overall structural stability of the equipment.

[0032] The second motor 6 is located on the top surface of the sewage treatment tank 1, near the fixed frame 10. It is responsible for driving the operation of the auxiliary equipment. The second motor 6 provides additional power support to the system to ensure the efficient operation of the entire equipment.

[0033] To achieve the above-mentioned utility model objectives, such as Figure 2-5 As shown, this utility model provides a sludge removal device for sewage treatment. The cleaning component 7 includes a first gear 71, scrapers 73 are fixedly spaced on the inner wall of the first gear 71, guide grooves 74 are opened at both the upper and lower ends of the circumference of the first gear 71, a second gear 72 is meshed on one side of the first gear 71, and the output end of the second motor 6 is connected to the center of the top surface of the second gear 72.

[0034] Specifically, the first gear 71, as the core driving component of the cleaning assembly 7, is responsible for starting and driving the operation of the entire cleaning system. Through meshing with the second gear 72, the first gear 71 transmits power to the cleaning assembly 7, thereby driving the scraper 73 to clean along the inner wall of the sewage treatment tank 1. Multiple scrapers 73 are evenly spaced on the inner wall of the first gear 71. These scrapers 73 are in contact with the tank wall and achieve effective cleaning through gear rotation, thus removing the attached sludge and impurities in a timely manner.

[0035] The guide groove 74 is set at the upper and lower ends of the circumference of the first gear 71 to guide and ensure the stability of the gear rotation. At the same time, the guide groove 74 enables the first gear 71 to cooperate with the guide wheel in the sewage treatment tank 1 to ensure the smooth rotation of the gear and prevent the scraper 73 from shaking or colliding with the tank wall, thereby improving the cleaning effect.

[0036] The second gear 72 meshes with the first gear 71, driving the first gear 71 to rotate, which in turn drives the scraper 73 to clean along the pool wall. The operation of the second gear 72 is the key to the movement of the entire cleaning assembly 7, ensuring that the scraper 73 can clean the inner wall of the sewage pool evenly.

[0037] The second motor 6 provides power to the entire cleaning system, driving the rotation of the second gear 72. The power output from the second motor 6 is transmitted to the first gear 71 through the second gear 72, thereby driving the scraper 73 to rotate and completing the entire cleaning process.

[0038] The working principle of this utility model is as follows: The cleaning component 7, through the meshing of the first gear 71 and the second gear 72, drives the scraper 73 to rotate along the inner wall of the sewage tank, removing sludge and impurities from the tank wall. The scraper 73 efficiently cleans the sludge adhering to the inner wall through the rotation of the gears, preventing the accumulation of dirt. The sludge at the bottom of the sewage tank is transported to the guide box 2 through the guide pipe 9 and the auger 8. The rotation of the auger 8 helps to smoothly send the sludge at the bottom of the tank into the guide box 2, ensuring the effective transfer of sludge. The sludge received by the guide box 2 is discharged through the discharge pipe 5. The discharge pipe 5 is connected to the vacuum pump 4. The vacuum pump 4 generates negative pressure to smoothly suck out the sludge and discharge it into an external treatment system or storage container. The first motor 3 and the second motor 6 provide power to the equipment. The first motor 3 drives the auger 8 to rotate, and the second motor 6 drives the gears in the cleaning component 7, ensuring the efficient operation of the entire equipment.

[0039] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
