Description

Technical Field

[0001] The utility model relates to a device for quickly fixing and disassembling a liftable aerator. Background Art

[0002] At present, in the sewage treatment process, the liftable aerator is a device that can directly lift the aerator out of the water, which can be quickly cleaned and maintained, so that the aeration system is in the best working state, thereby reducing fan loss, maintaining high power efficiency, and reducing operating costs. It is easy to install and can be installed with or without water in the pool. If long-term aeration requires maintenance, it can be freely lifted and repaired without draining water or shutting down the fan, which does not affect normal operation; the liftable aerator is generally fixed with a pipe clamp seat, and the installation position is located in the biological pool, which requires the installer to fix it by tightening the nut. The biological pool is deep, and there are great safety hazards during the construction of the pool top, and the installation quality cannot be guaranteed. Summary of the invention

[0003] The utility model aims to provide a device for quickly fixing and disassembling a liftable aerator, which can greatly simplify the disassembly and buckle fixing operations of the liftable aerator, and is conducive to reducing safety hazards.

[0004] The purpose of the device is achieved as follows: a device for quickly fixing and disassembling a liftable aerator, including an aeration fixing link fixedly arranged horizontally on the side wall of the liftable aerator, the free end of the aeration fixing link is connected to a disassembly link through a pin shaft, a fixing sleeve is vertically arranged in the free end of the disassembly link, a spherical nut and a reset spring are arranged in the fixing sleeve, the top surface of the free end of the disassembly link is provided with a snap-fit ​​hole, the top surface of the spherical nut extends upward from the snap-fit ​​hole, a fixing seat plate is arranged on one side wall of the biological pool, a pool wall fixing link is horizontally fixed to the fixing seat plate, a snap-fit ​​hole is also arranged on the top surface of the free end of the pool wall fixing link, the disassembly link extends into the pool wall fixing link, and the top of the spherical nut extends upward from the two snap-fit ​​holes in turn.

[0005] This device utilizes a spherical locking structure to achieve the function of rapid fixation and disassembly of the liftable aerator. When the aeration device is lowered into place along the guide rod, the pool wall fixing rod and the liftable aerator rod are buckled together through the spherical locking structure to complete the fixation of the liftable aerator. When disassembly is required, the liftable aerator can be disassembled by simply pressing the spherical nut in the locking structure. Compared with the prior art, the advantages of the utility model are: 1. The device is easy to manufacture and low in cost. 2. It is easy to install, and the disassembly and assembly process is safe and reliable. 3. The equipment investment is small. 4. It is easy to repair and maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0010] In the above-mentioned Figure 1 , 2 In: A device for quickly fixing and disassembling a liftable aerator, comprising an aeration fixing link 2 fixedly arranged horizontally on the side wall of the liftable aerator, the free end of the aeration fixing link 2 being connected to a disassembly link 3 through a pin 8, a fixing sleeve 4 being vertically arranged in the free end of the disassembly link 3, a spherical nut 5 and a reset spring 7 being arranged in the fixing sleeve 4, a buckling hole being provided on the top surface of the free end of the disassembly link 3, the top surface of the spherical nut 5 extending upward from the buckling hole, a fixing seat plate 9 being arranged on one side wall of the biological pool, a pool wall fixing link 6 being horizontally fixedly connected to the fixing seat plate 9, a buckling hole being also provided on the top surface of the free end of the pool wall fixing link 6, the disassembly link 3 extending into the pool wall fixing link 6, the top end of the spherical nut 5 extending upward from the two buckling holes in sequence.

[0011] The principle of the ball locking mechanism is as follows: the top of the installation end of the disassembly connecting rod 3 is provided with a buckle hole, and the ball nut 5 and the return spring 7 are installed together into the fixing sleeve 4, and then the whole is inserted into the disassembly connecting rod 3. When the ball nut 5 is exposed from the buckle hole at the top of the disassembly connecting rod 3, the locking structure is installed in place. The installation end of the pool wall fixing connecting rod 6 also has a buckle hole. When the disassembly connecting rod 3 is buckled with the pool wall fixing connecting rod 6, the ball nut 5 will be squeezed downward. When the ball nut 5 reaches the buckle hole of the pool wall fixing connecting rod 6, the return spring 7 pushes the ball nut 5 to the buckle hole, completing the buckle process of the locking structure. When disassembly is required, just press the ball nut 5 downward to make it disengage from the buckle hole, completing the disassembly process of the locking structure.

[0012] The installation process is as follows: First, hoist the liftable aerator 1 from the biological pool into place, determine the installation position of the fixed seat plate 9, and securely fix it to the pool wall with expansion bolts. Secondly, install the disassembly link 3 with the aeration fixed link 2 using the pin 8. Finally, snap the installed disassembly link 3 into place with the pool wall fixed link 6, adjust it to a horizontal position, and firmly weld the pool wall fixed link 6 to the fixed seat plate 9 to complete the first installation and fixing process of the liftable aerator 1.

[0013] The disassembly process is as follows: when disassembly is required, simply press the ball nut 5 downward with a suitable tool to disengage the buckles of the disassembly connecting rod 3 and the pool wall fixing connecting rod 6, gently push the lifting rod of the liftable aerator 1 inward, and use the freedom of the hinged structure of the detachable connecting rod 3 and the aeration fixing connecting rod 2 to easily achieve the disassembly of the liftable aerator 1.
