Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a center-driven half-bridge single-pipe sludge suction machine. Background Technology

[0002] In wastewater treatment, sedimentation tanks are a crucial component. Their function is to separate suspended solids in wastewater by gravity, thereby achieving solid-liquid separation and improving water quality. After a period of operation, a large amount of sludge accumulates at the bottom of the sedimentation tank, which needs to be cleaned promptly; otherwise, it will affect the sedimentation effect and subsequent treatment processes.

[0003] Traditional sludge suction equipment has many drawbacks. Some sludge suction machines have complex structures, making installation and maintenance difficult, which increases operating costs and downtime. During the sludge suction process, some sludge suction equipment suffers from uneven sludge suction due to unreasonable suction arm design, making it difficult to effectively remove sludge from the edges or corners of the sedimentation tank, resulting in sludge residue and affecting the overall treatment efficiency of the sedimentation tank.

[0004] Furthermore, the skimming effect is also an important indicator for evaluating the performance of sludge suction equipment. Previous equipment had simple skimming components that could not effectively collect scum from the pool surface, causing it to re-mix into the water and degrade water quality. In addition, traditional equipment had inadequate support structures, making it prone to shaking and shifting during long-term operation, affecting the equipment's lifespan and suction efficiency. Utility Model Content

[0005] To address some of the problems existing in the prior art, this utility model provides a center-driven half-bridge single-pipe sludge suction machine. By rationally designing the center drive device, single-pipe sludge suction arm, skimming assembly, and support structure, it aims to improve the sludge cleaning efficiency and water treatment effect of sedimentation tanks, and meet the needs of modern sewage treatment.

[0006] To achieve the above objectives, this utility model provides a center-driven half-bridge single-tube sludge suction machine, including a sludge suction machine body. The sludge suction machine body includes a pool body. A center drive device is arranged at the center of the pool body. A working bridge is arranged on one side of the center drive device. A single-tube sludge suction arm is arranged in conjunction with the center drive device. The single-tube sludge suction arm has a hollow structure, with one end connected to the center drive device. Under the drive of the center drive device, it moves in a circular motion around the center of the pool body. A support structure is provided in conjunction with the center drive device. A skimming component is arranged between the single-tube sludge suction arm and the working bridge. A sludge suction transmission device is arranged in conjunction with the center drive device. A sludge discharge pipe is connected to the single-tube sludge suction arm. A water outlet pipe is arranged in conjunction with the sludge discharge pipe.

[0007] As a further improvement of this utility model, in order to accurately control the movement speed and direction of the single-tube sludge suction arm and ensure the accuracy and efficiency of the sludge suction operation, the central drive device includes an installation platform, on which a drive motor is installed. The drive motor is equipped with a reducer, which is connected to the input end of the reducer. The reducer is connected to the sludge suction transmission device, and the reducer is connected to the single-tube sludge suction arm through the sludge suction transmission device to drive the single-tube sludge suction arm to perform circular motion around the center of the pool.

[0008] As a further improvement of this utility model, in order to stably transmit power from the central drive device to the single-tube suction arm and ensure the stability of the single-tube suction arm when it makes a circular motion around the center of the pool, the suction transmission device includes a central rotating cylinder set in the pool, a central support column is set inside the central rotating cylinder, a rotary support platform is set on the top of the central support column, the central support column is connected to the central drive device, and the central rotating cylinder is connected to the single-tube suction arm.

[0009] As a further improvement of this utility model, in order to ensure that the amount of mud suctioned in each part is relatively uniform when the single-tube mud suction arm makes a circular motion and improve the mud suction efficiency, a plurality of mud suction holes are evenly distributed on the single-tube mud suction arm. The diameter of the mud suction holes gradually increases from the end closer to the central drive device to the end farther away from the central drive device, and a filter screen is provided at the mud suction hole. The mesh size of the filter screen is 0.5-2mm.

[0010] As a further improvement of this utility model, in order to effectively collect the scum and mud on the horizontal surface of the pool and discharge them through the scum funnel, thereby improving the efficiency and quality of skimming, the skimming assembly includes a scum rake plate set on the horizontal surface of the pool, a triangular support frame connected below the scum rake plate, a mud rake arm set below the triangular support frame, and the pool is also provided with a scum funnel for use in conjunction with the scum rake plate for scum discharge.

[0011] As a further improvement of this utility model, in order to provide stable support for the skimming assembly and the single-tube suction arm and ensure stability and safety during operation, the support structure includes a column support frame, connectors and diagonal braces. The connectors are installed on the skimming assembly and the single-tube suction arm, and the skimming assembly and the single-tube suction arm are connected to the column support frame through the diagonal braces.

[0012] When this utility model is in operation, the drive motor on the mounting platform rotates and transmits power to the reducer connected to it. After the reducer makes reasonable adjustments to the power, it transmits the power to the single-tube suction arm through the sludge suction transmission device.

[0013] The central support column in the sludge suction transmission device is tightly connected to the central drive device, providing stable support for the central rotating drum. Driven by power, the central rotating drum begins to rotate, which in turn drives the connected single-tube sludge suction arm to perform a circular motion around the center of the tank. As the core component of the sludge suction system, the single-tube sludge suction arm has multiple suction holes evenly distributed on it, with the diameter of the suction holes gradually increasing from the end closest to the central drive device to the end furthest away. This design allows for the rational distribution of sludge suction volume based on the distance from the center of the sedimentation tank during the rotation of the single-tube sludge suction arm, ensuring uniform sludge suction. Simultaneously, the filter screens installed at the suction holes, with a mesh size of 0.5-2mm, effectively filter out large particles of impurities, preventing impurities from entering the sludge suction system and protecting the normal operation of subsequent equipment.

[0014] While the single-tube suction arm is performing suction operations, the skimming component is also working. The scum rake plate, set on the horizontal plane of the pool, collects the scum on the surface of the pool as the equipment operates. The triangular support frame below the scum rake plate provides stable support, while the sludge rake arm below further collects the sludge. The collected scum and sludge are guided by the scum rake plate into the scum funnel used in conjunction with the scum rake plate, and are finally discharged from the pool.

[0015] Throughout the entire operation, the support structure plays a crucial role. The support frame is connected to the skimming assembly and the single-pipe suction arm via connectors, and additional support and fixation are provided by diagonal bracing, ensuring the stability of the skimming assembly and the single-pipe suction arm during operation and reducing equipment deformation or failure caused by factors such as vibration.

[0016] The beneficial effects of this utility model are as follows:

[0017] High-efficiency sludge suction and uniform treatment: Multiple suction holes are evenly distributed on the single-tube sludge suction arm, and the diameter of the suction holes gradually increases from the end closer to the central drive device to the end farther away. This design allows the suction holes at different positions to rationally distribute the amount of sludge suctioned according to their distance from the center when the sludge suction arm moves in a circular motion around the center of the tank, ensuring the uniformity of sludge suction, improving sludge suction efficiency, ensuring that all areas in the sedimentation tank are effectively cleaned, and reducing sludge residue.

[0018] Superior Filtration and Equipment Protection: The filter screen installed at the sludge suction port has a mesh size of 0.5-2mm, which effectively filters out large particles of impurities and prevents them from entering the sludge suction system. This not only ensures the quality of sludge suction but also avoids impurities causing wear and blockage to subsequent equipment, extending the service life of the equipment and reducing maintenance costs.

[0019] Excellent skimming effect: The scum rake plate, triangular support frame, and mud rake arm in the skimming component work together to efficiently collect scum and mud from the horizontal surface of the pool. The scum rake plate concentrates the scum, while the mud rake arm further collects the mud, which is then discharged through the scum funnel, effectively reducing the impurity content in the pool and improving the water treatment effect.

[0020] Stable Transmission and Operation: The central drive unit transmits power stably to the sludge suction transmission device via a drive motor and reducer mounted on the platform, thereby driving the single-tube sludge suction arm in circular motion. The design of the central support and central rotating drum of the sludge suction transmission device ensures the smoothness and reliability of power transmission, reduces vibration and noise during operation, and improves the operational stability of the equipment.

[0021] Stable Support and Safety Assurance: The support structure employs a combination of pillar support frames, connectors, and diagonal braces, providing stable support for the skimming assembly and single-pipe suction arm. The diagonal braces effectively distribute stress, reduce component deformation, and ensure the safety and stability of the equipment during operation. Attached Figure Description

[0029] The central drive device 2 includes a mounting platform 9, on which a drive motor 10 is mounted. The drive motor 10 is equipped with a reducer 11, which is connected to the input end of the reducer 11. The reducer 11 is connected to the sludge suction transmission device 7, and the reducer 11 is connected to the single-tube sludge suction arm 4 through the sludge suction transmission device 7 to drive the single-tube sludge suction arm 4 to perform circular motion around the center of the pool body 1.

[0030] The sludge suction transmission device 7 includes a central rotating cylinder 12 disposed in the pool body 1. A central support column 13 is disposed inside the central rotating cylinder 12. A rotating support platform 14 is disposed on the top of the central support column 13. The central support column 13 is connected to the central drive device 2. The central rotating cylinder 12 is connected to the single-tube sludge suction arm 4.

[0031] The single-tube suction arm 4 has a plurality of suction holes 15 evenly distributed on it. The diameter of the suction holes 15 gradually increases from the end closer to the central drive device 2 to the end farther away from the central drive device 2. A filter screen is provided at the suction holes 15, and the mesh size of the filter screen is 0.5-2mm.

[0032] The skimming assembly 6 includes a scum rake plate 16 disposed on the horizontal plane of the pool body 1. A triangular support frame 17 is connected and disposed below the scum rake plate 16. A sludge rake arm 18 is disposed below the triangular support frame 17. The pool body 1 is also provided with a scum funnel 19 for use in conjunction with the scum rake plate 16 for scum discharge.

[0033] The support structure 5 includes a column support frame 20, a connector 21, and a tie rod 22. The connector 21 is installed on the skimming assembly 6 and the single-tube suction arm 4.

[0035] The central support column 13 in the sludge suction transmission device 7 is tightly connected to the central drive device 2, providing stable support for the central rotating drum 12.

The single-tube sludge suction arm 4 is the core component of sludge suction. It has multiple sludge suction holes 15 evenly distributed on it, and the diameter of the sludge suction holes 15 gradually increases from the end closer to the central drive device 2 to the end farther away.

The triangular support frame 17 below the scum rake plate 16 provides stable support for it, and the mud rake arm 18 below it further collects the mud. The collected scum and mud are guided by the scum rake plate 16 and enter the scum funnel 19 that works with the scum rake plate 16, and are finally discharged from the pool body 1.

[0037] Throughout the entire operation, the support structure 5 plays an important role; the support frame 20 is connected to the skimming assembly 6 and the single-pipe suction arm 4 through the connector 21, and is further supported and fixed by the diagonal tie rod 22, ensuring the stability of the skimming assembly 6 and the single-pipe suction arm 4 during operation, and reducing equipment deformation or failure caused by vibration and other factors.
