Description

Technical Field

[0001] This utility model relates to the field of propeller technology, specifically a pneumatic propeller. Background Technology

[0002] In wastewater treatment, integrated reactors are typically equipped with flow promoters. The function of these promoters is to propel water forward at a constant flow rate or to agitate it. This process includes mixing wastewater, stirring sludge, propelling the water medium, maintaining flow velocity at the bottom of the reactor, preventing sludge settling, and improving wastewater treatment efficiency. Flow promoters are usually installed using a lifting structure. The typical operation involves securing the promoter to a support rod with screws and flanges, and then lowering it into the reactor using a hoisting method.

[0003] Traditional flow mixers work by using stirring blades mounted on the outer wall of a motor to rotate under the motor's power. However, prolonged immersion of the motor in water accelerates its damage, significantly reducing the equipment's lifespan and rendering it unable to effectively mix wastewater. This necessitates regular maintenance, increasing operating costs. Utility Model Content

[0006] As a preferred technical solution of this utility model: the inner cavity of the vent pipe is connected to the inner cavity of the outer shell, and the connecting pipe is a high-pressure rubber hose.

[0007] As a preferred technical solution of this utility model: the inner wall shape of the limiting plate matches the outer wall shape of the track, and both the limiting plate and the locking hole are made of stainless steel.

[0009] As a preferred technical solution of this utility model: the outer wall diameter of the locking rod matches the inner wall diameter of the sealing plate, a controller is installed on the outer wall of the housing, and the controller is electrically connected to the waterproof motor.

[0010] As a preferred technical solution of this utility model: there are two support plates, and the two support plates are respectively installed on the top and bottom of the limiting plate, and sealing gaskets are installed on the outer edges of the moving plate and the closing plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This pneumatic agitator, through a drive shaft set in the inner cavity of the housing and drive blades set on the outer wall of the drive shaft, releases gas into the inner cavity of the housing through the air pipe and connecting pipe. Under the action of the gas, the drive blades are driven to rotate, and the rotation of the drive blades drives the rotation of the drive shaft. Thus, the stirring blades on the outer wall of the drive shaft stir the water in the pool, avoiding the problem of short motor life in traditional equipment. The pneumatic method can be more stable.

[0013] 2. This pneumatic actuator, through a support plate set on the outer wall of the limiting plate and a movable plate set in the inner cavity of the support plate, causes the movable plate to drive the locking rod to move under the action of the drive screw, thereby allowing the locking rod to enter the inner cavity of the locking hole, thus fixing the equipment. This avoids the need for continuous traction of the lifting rope in the traditional method, reduces the pressure on the lifting rope, and ensures the stability of the lifting rope for long-term use.

[0022] By using the locking hole 2 provided in the inner cavity of the outer shell 3 and the drive fan blade 6 installed on the outer wall of the locking hole 2, when air is supplied to the inner cavity of the outer shell 3 through the air pipe 7 and the connecting pipe 8, the drive fan blade 6 can be pushed to move under the action of the air, and then the drive shaft 4 can be rotated under the drive of the rotation of the drive fan blade 6. At this time, the water flow can be pushed by the action of the stirring blade 5.

[0023] In a preferred embodiment, the inner cavity of the vent pipe 7 is connected to the inner cavity of the outer shell 3, and the connecting pipe 8 is a high-pressure rubber hose.

[0024] By providing a vent pipe 7 on the outer wall of the outer casing 3 and a connecting pipe 8 on the outer wall of the vent pipe 7, when air is supplied to the inner cavity of the outer casing 3 through the connecting pipe 8 and the vent pipe 7, the drive shaft 4 can be rotated under the push of the air, thereby driving the stirring blade 5. Under the action of the stirring blade 5, the water can be stirred.

[0025] In a preferred embodiment, the inner wall shape of the limiting plate 9 matches the outer wall shape of the track 1, and both the limiting plate 9 and the locking hole 2 are made of stainless steel.

[0026] By setting a limiting plate 9 on the outer wall of the outer shell 3, when the outer shell 3 is lifted by the lifting equipment at the side of the pool, the limiting plate 9 can move back and forth along the outer wall of the track 1, thereby enabling the outer shell 3 to move up or down along the outer wall of the track 1.

[0027] In a preferred embodiment: the outer wall shape of the movable plate 13 matches the inner wall shape of the support plate 10, and the outer wall of the closed plate 12 is provided with a movable hole, and the inner wall diameter of the movable hole matches the outer wall diameter of the locking rod 14.

[0028] By using a waterproof motor 11 and a drive screw 15 installed in the inner cavity of the support plate 10, the moving plate 13 can be driven by the waterproof motor 11 and the drive screw 15, so that the moving plate 13 moves along the inner wall of the support plate 10, thereby causing the locking rod 14 on the outer wall of the moving plate 13 to extend out of the inner cavity of the support plate 10 and enter the inner cavity of the locking hole 2, thereby locking the position of the limiting plate 9.

[0029] In a preferred embodiment: the outer diameter of the locking rod 14 matches the inner diameter of the sealing plate 12, a controller is installed on the outer wall of the housing 3, and the controller is electrically connected to the waterproof motor 11.

[0030] The waterproof motor 11 is controlled by a controller installed on the outer wall of the outer casing 3. When the position of the outer casing 3 needs to be adjusted, the height of the outer casing 3 is adjusted by the lifting equipment next to the pool. After the adjustment is completed, the waterproof motor 11 can be started by the controller. Under the action of the waterproof motor 11, the moving plate 13 is moved, so that the outer wall of the locking rod 14 enters the inner cavity of the locking hole 2, thereby locking the position of the support plate 10 and the limiting plate 9.

[0031] In a preferred embodiment, there are two support plates 10, and the two support plates 10 are respectively installed on the top and bottom of the limiting plate 9, and sealing gaskets are installed on the outer edges of the moving plate 13 and the closing plate 12.

[0032] By using the support plates 10 provided at the top and bottom of the limiting plate 9, and the waterproof motor 11 and drive screw 15 provided in the inner cavity of the support plate 10, the moving plate 13 in the support plate 10 can be pushed outward by the action of the waterproof motor 11 on the upper and lower sides, so that the outer wall of the locking rod 14 enters the inner cavity of the locking hole 2. At this time, the stability of the outer shell 3 can be ensured by fixing the locking rod 14 on the upper and lower sides. By using the sealing gaskets installed on the outer walls of the sealing plate 12 and the moving plate 13, water flow is prevented from entering the inner cavity of the support plate 10.

[0033] Working principle: When the above equipment is used to agitate the water tank, the outer shell 3 is released downwards by the lifting device set next to the water tank, so that the limiting plate 9 can move downwards along the outer wall of the track 1. When the outer shell 3 is moved into the water, the waterproof motor 11 is started under the action of the controller on the outer wall of the outer shell 3. Under the action of the waterproof motor 11, the drive screw 15 rotates, which in turn drives the outer wall of the moving plate 13 to move forward along the inner cavity of the support plate 10, so that the outer wall of the locking rod 14 enters the inner cavity of the locking hole 2, thus locking the position of the outer shell 3 and fixing the outer shell 3 to the outer wall of the track 1. Then, air is supplied to the inner cavity of the outer shell 3 through the connecting pipe 8 and the air pipe 7. Under the push of the air, the drive fan blade 6 rotates under the action of the air. During the rotation of the drive fan blade 6, the drive shaft 4 and the stirring blade 5 are driven to rotate, thereby agitating the water flow.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
