Description

Technical Field

[0001] This utility model relates to the technical field of aeration disc systems, specifically to a lifting device for a microporous aeration disc system. Background Technology

[0002] The microporous aeration disc system is the core aeration equipment in the biological treatment section of wastewater treatment. It consists of a disc-shaped diffuser with tiny pores made of corrosion-resistant material, which is usually installed at the bottom of the tank and connected to the air supply network. Its working principle is that air is delivered to the aeration disc by a high-pressure blower. The air is cut through the micropores to form tiny bubbles, thereby increasing the gas-liquid contact area and allowing oxygen to dissolve efficiently in the mixed liquid to meet the metabolic needs of aerobic microorganisms.

[0003] Existing microporous aeration disc systems suffer from reduced biochemical treatment efficiency when the microporous aeration discs or connecting pipes are damaged due to vibration during wastewater treatment. Since the aeration system is usually submerged at the bottom of the wastewater tank and cannot be isolated for maintenance during operation, the entire wastewater treatment system must be shut down and the wastewater in the tank emptied before the corresponding parts or pipes can be replaced or repaired. This is not only time-consuming and labor-intensive, but also seriously affects the continuous operation efficiency of the wastewater treatment plant. Utility Model Content

[0004] The purpose of this utility model is to provide a microporous aeration disc system lifting device to solve the above problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution, including:

[0018] 1. This utility model uses multiple sets of hoists to synchronously drive the screw to rotate, thereby driving the microporous aeration disc system on the bracket to rise synchronously along the guide rod and detach from the liquid surface.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] like Figures 1-2 As shown, in one embodiment, a lifting device for a microporous aeration disc system includes: a bracket 1 for supporting the microporous aeration disc system 10; wherein the bracket 1 is detachably mounted on a guide rod 2, and a screw 3 is symmetrically arranged on one side of the guide rod 2, and a gate opener 4 is mounted on the top of the screw 3.

[0027] It is understandable that when the hoist 4 is started, it can drive the screw 3 to rotate, thereby driving the bracket 1 and the microporous aeration disc system 10 fixed on it to rise synchronously along the guide rod 2, so that the microporous aeration disc system 10 is removed from the liquid surface. This allows the aeration disc system or pipeline to be inspected or replaced separately without stopping the operation of the sewage treatment system, which effectively improves maintenance efficiency and reduces downtime losses.

[0028] Please continue reading. Figures 1-2 In this embodiment, the guide rod 2 is vertically installed inside the aeration tank 9 to provide stable guidance when the bracket 1 is raised and lowered, ensuring that the microporous aeration disc system 10 does not shift or tilt during the raising and lowering process. Specifically, two sets of guide rods 2 are symmetrically arranged along the diagonal of the bracket 1, extending from the bottom to the top of the aeration tank 9, which can effectively balance the force on the bracket 1 and prevent structural deformation or jamming caused by uneven force during the raising and lowering process.

[0029] Furthermore, a guide sleeve 5 is fitted onto the outside of the guide rod 2, and a support plate 6 is provided on one side of the guide sleeve 5. Specifically, the top of the guide sleeve 5 is snapped and fixed to the bottom of the bracket 1, while the top end face of the support plate 6 abuts against the bottom end face of the bracket 1, thus forming a stable support structure. It can be understood that when the bracket 1 is raised or lowered, the guide sleeve 5 slides along the guide rod 2 to ensure smooth movement, while the support plate 6 can share part of the load, preventing the guide rod 2 from bearing excessive bending moment, thereby extending the overall service life.

[0030] Furthermore, the screw 3 is symmetrically arranged on the outside of the guide rod 2, and the screw 3 and the guide rod 2 are parallel to each other. Specifically, the bottom of the screw 3 is rotatably connected to the edge of the bracket 1 (e.g., bearing or hinge structure), while the top of the screw 3 passes through the top edge of the aeration tank 9 and is connected to the hoist 4.

[0031] Understandably, when the screw 3 rotates, the bracket 1 rises and falls under the action of the threaded transmission, while the guide sleeve 5 slides along the guide rod 2 to ensure that the lifting process is smooth and without deviation, thus ensuring the reliability of the transmission and avoiding the problem of the bracket 1 tilting or jamming due to uneven force.

[0032] It should be noted in detail that the bracket 1 is provided with a connecting rod 7, and a counterweight 8 is detachably installed on the connecting rod 7. Specifically, the counterweight 8 is arranged between the microporous aeration discs, and the counterweight 8 is symmetrically arranged along another diagonal of the bracket 1.

[0033] Understandably, the counterweight 8 can balance the vibration and buoyancy effects of the aeration system during operation, so that the entire microporous aeration disc system 10 can be stably pressed to the bottom of the aeration tank 9 during operation, avoiding shaking, displacement or damage caused by water flow impact or aeration disturbance, thereby improving the stability and service life of the equipment.

[0034] Please continue reading. Figures 1-2 In this embodiment, the gate hoists 4 are arranged facing each other and are electrically connected by wires. Specifically, the gate hoists 4 are symmetrically installed on the top edge of the aeration tank 9, and the output end of the gate hoist 4 is rotatably connected to the top of the screw 3.

[0035] Understandably, the two sets of hoists 4 can be linked by an external electrical control device (such as a PLC or a synchronous controller) to ensure consistent lifting speed, avoid tilting or jamming at both ends of the bracket 1 due to asynchronous lifting, and thus improve the reliability and ease of maintenance of the system.

[0036] Working principle: During normal operation, the counterweight 8 balances the vibration and buoyancy of the aeration system, ensuring that the entire microporous aeration disc system 10 is stably pressed against the bottom of the aeration tank 9, preventing shaking, displacement, or damage caused by water flow impact or aeration disturbance. When maintenance or component replacement is required, the hoist 4 starts the drive screw 3 to rotate forward, causing the microporous aeration disc system 10 and pipelines to slowly rise along the guide rod 2 via the bracket 1. When the microporous aeration disc system 10 is above the liquid surface, maintenance personnel can perform maintenance or replacement of the aeration disc system or pipelines independently without stopping the sewage treatment system. After maintenance, the hoist 4 starts the drive screw 3 to rotate in the reverse direction, causing the microporous aeration disc system 10 and pipelines to slowly descend along the guide rod 2 via the bracket 1.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
