Description

TECHNICAL FIELD

[0001] The utility model relates to sewage treatment equipment technical field, concretely relates to a adjustable lifting aeration device. BACKGROUND

[0002] In the activated sludge process of sewage treatment, the performance of the aeration device plays a key role in the sewage treatment effect. The traditional lifting aeration device has exposed many problems in practical application:

[0003] Aeration quantity and immersion depth adjustment problem: the traditional aeration device mainly relies on valve control to adjust the aeration quantity, which has limitations and cannot accurately adjust the immersion depth of the aeration head. In the sewage treatment process, different stages and different water quality have different requirements for the immersion depth of the aeration head. For example, in the early stage of treatment, the organic matter concentration in the sewage is high, and the microorganisms are active in metabolism, which requires a deep immersion depth of the aeration head to provide sufficient dissolved oxygen; while in the later stage of treatment, the demand for dissolved oxygen is reduced, and a shallow immersion depth of the aeration head can meet the requirements. The traditional aeration device cannot accurately adapt to these changes, resulting in poor aeration effect, affecting the efficiency and quality of sewage treatment.

[0004] Maintenance problem: when the traditional aeration device is overhauled, the entire aeration system usually needs to be hoisted as a whole. This process not only has complex operation, but also causes the sewage treatment system to completely stop production. The stoppage of the sewage treatment system will disrupt the entire sewage treatment process, increase the treatment cost, and may have a negative impact on the environment.

[0005] Deficiency of prior art: although the prior art adopts a segmented lifting structure to try to solve the above problems, it fails to effectively solve the coordination problem of height adjustment and air path compensation. During the height adjustment process, the air path may be blocked or leak due to the stretching and twisting of the pipeline, affecting the aeration effect and reducing the reliability and stability of the equipment.

[0006] In summary, these defects of the traditional lifting aeration device limit its application effect in sewage treatment, and there is an urgent need for a new type of aeration device to solve these problems, in order to improve the efficiency and quality of sewage treatment and reduce the maintenance cost. SUMMARY

[0007] The utility model discloses a purpose at providing a kind of adjustable lifting aeration device, solve the aeration head submergence depth of traditional lifting aeration device cannot be accurately adjusted, affect sewage treatment system operation when overhauling and height adjustment and air path compensation synergy are not good etc.

[0008] To solve the above technical problems, the utility model adopts the following technical scheme: an adjustable lifting aeration device, comprising aeration main pipe, a plurality of parallelly arranged aeration branch pipes, an aeration head arranged at the end of the branch pipe, an adjustable support assembly, a lifting mechanism and a fixed support; the aeration main pipe is arranged horizontally, the aeration branch pipe is arranged vertically, one end of which is communicated with the aeration main pipe, and the other end is communicated with the aeration head; the support assembly is arranged between the fixed support and the aeration main pipe, and a support cross bar is arranged, the lifting mechanism comprises a lifting chain, a lifting motor and a sleeve ring; a fixed cross bar is arranged between the fixed supports, and the fixed cross bar is provided with a longitudinal sliding rail for facilitating the upward and downward sliding of the aeration branch pipe.

[0009] Preferably, the sleeve ring is sleeved with the fixed cross bar on the fixed support, and is fixedly connected with the lifting chain.

[0010] Preferably, a flexible connecting piece is arranged between the support cross bar and the aeration branch pipe.

[0011] Preferably, a wear-resistant guide strip is embedded in the longitudinal sliding rail of the fixed support.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] (1) The independent lifting unit design allows a single set of aeration branch pipes to be lifted above the water surface when maintenance is required, without affecting the normal operation of the entire sewage treatment system. This greatly reduces the impact of equipment maintenance on the sewage treatment system, reduces maintenance costs and improves equipment efficiency.

[0014] (2) The sliding rail guide structure, i.e. the guide block moves along the longitudinal sliding rail and cooperates with the anti-deviation roller, ensures that the aeration branch pipe does not deviate during lifting, ensuring the stability and accuracy of lifting. At the same time, the arrangement of the wear-resistant guide strip reduces the wear between components and prolongs the service life of the equipment. BRIEF DESCRIPTION OF DRAWINGS

[0020] The following will describe in detail the specific implementation method of this adjustable and liftable aeration device in practical applications:

[0021] Installation steps:

[0022] Fixing bracket installation: First, anchor the fixing bracket 6 to the bottom of the sewage treatment tank according to the design requirements. Ensure that the fixing bracket 6 is securely installed, with the longitudinal slide rail 61 vertical and flat, and the position accurate, providing a stable foundation for the installation of subsequent components.

[0023] Aeration main pipe connection: Connect the ring-shaped aeration main pipe 1 with the external gas supply pipeline, ensuring a good seal and no gas leakage. After the connection is completed, install the aeration main pipe 1 on the fixing bracket 6, so that it is in the appropriate position for subsequent connection with the aeration branch pipe 2.

[0024] Aeration branch pipe installation: Install multiple sets of parallel aeration branch pipes 2 on the aeration main pipe 1 at equal intervals, ensuring a tight connection. Then, connect the support crossbar 41 with the aeration branch pipe 2 through a flexible connection pipe. The flange connection discs at both ends of the flexible connection pipe are securely connected with the support crossbar 41 and the aeration branch pipe 2 through bolts and other connecting components, ensuring the airtightness and stability of the gas path.

[0025] Lifting mechanism installation: Connect one end of the lifting chain 51 to the aeration branch pipe 2 through a collar 53, and the other end to the lifting motor 52, ensuring the stability of the aeration branch pipe 2 during lifting. Install a quick-release clamp on the appropriate position of the lifting chain 51, and prepare a safety pin to lock the lifting chain 51 when needed.

[0026] Height adjustment steps:

[0027] When the height of the aeration head 3 needs to be adjusted, the operator controls the lifting motor 52 to move up and down, controlling the position of the aeration branch pipe 2. Since the support crossbar 41 is connected to the aeration branch pipe 2 through a flexible connection pipe, the aeration branch pipe 2 and the aeration head 3 are lifted synchronously.

[0028] When the aeration head 3 reaches the predetermined position, insert the limit pin into the corresponding positioning hole of the fixing bracket 6 to lock the height of the aeration head 3.

[0029] Maintenance steps:

[0030] When a group of aeration branch pipes 2 needs to be maintained, first open the safety pin of the corresponding lock unit of the aeration branch pipe 2.

[0031] Start the lifting device and slowly lift the group of aeration branch pipes 2 above the water surface through the lifting chain 51. Then, maintain the aeration branch pipe 2 and its related components that have been lifted above the water surface, such as checking whether the aeration head 3 is blocked or the flexible connection pipe is damaged.

[0032] After maintenance is completed, slowly lower the aeration branch pipe 2 to its original position, reinsert the safety pin, and lock the lifting chain 51 to restore the group of aeration branch pipes 2 to normal operating condition.

[0033] Through the above specific embodiments, the adjustable and liftable aeration device can effectively realize accurate adjustment of the height of the aeration head, independent lifting and maintenance of a single group of branch pipes, and guarantee the stability of the equipment and the smoothness of the air path during operation, thereby providing an efficient and reliable aeration equipment solution for the wastewater treatment industry.
