Description

TECHNICAL FIELD

[0001] The utility model relates to the field of environmental protection technology, especially a kind of high-efficiency sedimentation tank. BACKGROUND

[0002] Sedimentation tank is the core equipment for realizing solid-liquid separation in sewage treatment process, which removes suspended particles in sewage through gravity settling principle. To improve sedimentation efficiency, honeycomb inclined pipe structure is widely used in sedimentation tank, which accelerates particle settling by increasing surface area and optimizing water flow path. However, in long-term operation, sludge is easy to accumulate on the surface and inside of inclined pipe, which leads to problems such as blockage and uneven water distribution, seriously affecting the treatment effect.

[0003] The Chinese utility model patent with authorization announcement number CN 221889253 U discloses a honeycomb inclined pipe sludge cleaning device, which expands the cleaning coverage by driving the spray pipe to move in multiple directions through horizontal and vertical transmission mechanisms. However, there are still deficiencies in the design of the spray pipe and nozzle: the nozzles are uniformly arranged along the bottom of the spray pipe, and the spray angle is fixed, making it difficult for the water flow to accurately penetrate the dense channel structure of the honeycomb inclined pipe, especially when the inclined pipes are closely arranged or the sludge is severely hardened, the cleaning effect is significantly reduced. In addition, the spray pressure is limited by the water level in the sedimentation tank, and if a local high-pressure jet cannot be formed, it is difficult to remove stubborn sludge inside the inclined pipe. Therefore, the spray pipe is usually located above the honeycomb inclined pipe, and the nozzle coverage is limited, and the water flow direction is difficult to penetrate the complex structure inside the honeycomb inclined pipe, resulting in incomplete cleaning of the bottom and deep areas of the inclined pipe, which still relies on manual assistance, low efficiency and high cost.

[0004] Therefore, there is an urgent need for a high-efficiency sedimentation tank that can adapt to the angle of inclined pipe, clean inside the honeycomb inclined pipe and cover the whole area, to solve the technical defects of low cleaning efficiency and poor adaptability in the prior art. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a kind of high-efficiency sedimentation tank, the sedimentation tank can adapt to the angle of honeycomb inclined pipe, clean inside the honeycomb inclined pipe and cover the whole area, to solve the technical defects of low cleaning efficiency and poor adaptability in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-efficiency sedimentation tank, including a sedimentation tank, a transverse transmission mechanism, a longitudinal transmission mechanism, and a cleaning mechanism. The cleaning mechanism includes a main pipe and a nozzle. The longitudinal transmission mechanism includes a longitudinal track and a traveling trolley movably mounted on the longitudinal track. A telescopic conduit connects the main pipe and the nozzle. The nozzle is equipped with a telescopic arm that extends the nozzle into the honeycomb inclined tube. The telescopic arm is controlled to extend or retract by a driving element. The telescopic arm is hinged to a rotating joint that makes its extension direction consistent with the inclination angle of the honeycomb inclined tube. The other end of the rotating joint is fixedly mounted on the traveling trolley. A locking mechanism for fixing the inclination angle of the telescopic arm is provided at the rotating joint. The transverse transmission mechanism and the longitudinal transmission mechanism cooperate to control the position of the nozzle at the opening of the honeycomb inclined tube. Through the coordinated control of the telescopic conduit, the rotating joint, the telescopic arm, the driving element, and the locking mechanism, the nozzle is made to penetrate deep into the interior for cleaning.

[0007] By adopting the above technical solution, through the setting of telescopic conduits and telescopic arms, and by controlling the extension and retraction length of the telescopic arms through drive elements, the nozzles can penetrate deep into the interior of the honeycomb inclined tubes, overcoming the limitation of surface cleaning only in existing technologies. The rotary joint adjusts the nozzle's spray angle to match the inclination angle of the honeycomb inclined tubes, ensuring precise water flow into the inclined tube channels and solving the compatibility problem of fixed spray angles. The locking mechanism fixes the inclination angle of the telescopic arm, preventing angle deviation due to water flow reaction force during cleaning and improving cleaning stability. Through the coordination of the transverse and longitudinal transmission mechanisms and multi-dimensional movement control, the nozzles fully cover the honeycomb inclined tube area of ​​the sedimentation tank, avoiding cleaning blind spots.

[0008] The rotary joint is further configured such that: the rotary joint includes an arc-shaped guide rail fixedly mounted on the traveling trolley and a slider fixedly mounted on the telescopic arm, the slider being slidably mounted on the arc-shaped guide rail for adjusting the tilt angle of the telescopic arm.

[0009] By adopting the above technical solution, the combination of arc-shaped guide rail and slider provides a continuous angle adjustment path, so that the tilt angle of the telescopic arm can be accurately adapted to the actual layout of the honeycomb inclined tube, thereby enhancing the cleaning flexibility.

[0010] The locking mechanism is further configured as follows: a gear plate is coaxially fixed on the arc-shaped guide rail, a locking pin is slidably disposed at the tail end of the telescopic arm, and a spring is used to control the locking pin to engage with the corresponding tooth groove of the gear plate.

[0011] By adopting the above technical solution, the angle of the telescopic arm is mechanically locked by the meshing of the toothed disc and the locking pin, and the spring pressure presses the locking pin into the tooth groove of the toothed disc, thus avoiding angle deviation caused by water flow impact during cleaning. The elastic design of the spring allows the operator to manually unlock the locking pin, which facilitates quick adjustment of the cleaning angle and improves the convenience of operation.

[0012] Further configuration: The telescopic arm consists of multiple nested sleeve sections.

[0013] By adopting the above technical solution, the telescopic arm is composed of multiple nested sleeves. Through step-by-step extension, the total length of the telescopic arm can be flexibly adjusted to meet the cleaning needs of honeycomb inclined tubes at different depths.

[0014] A further feature is provided: a guide plate is fixedly provided on the innermost sleeve, and the shape of the guide plate matches the cross-section of the honeycomb inclined tube.

[0015] By adopting the above technical solution, and by matching the guide plate with the cross-section of the honeycomb inclined tube, the nozzle can be accurately guided into the inclined tube channel, avoiding collision with the inclined tube structure during the extension and retraction process, and protecting the integrity of the device.

[0016] A further configuration is provided: a linear guide rail and a sliding groove matching the linear guide rail are provided between the adjacent sleeves, the linear guide rail is fixed to the inner wall of the outer sleeve, and the sliding groove is opened on the outer wall of the inner sleeve.

[0017] By adopting the above technical solution and using the sliding setting of the linear guide rail and the slide groove, the movement trajectory of each sleeve is stable during extension and retraction, reducing shaking and improving cleaning accuracy.

[0018] The drive element is further configured as follows: the drive element is a cylinder, the cylinder includes a cylinder body and a piston rod, the cylinder body is fixed inside the outer sleeve, and the end of the piston rod is connected to the innermost sleeve.

[0019] By adopting the above technical solution, the extension and retraction stroke of the telescopic arm is precisely controlled by the linear motion of the piston rod, resulting in fast response and stable operation, making it suitable for high-frequency cleaning operations.
