FIG. 3 is an enlarged view of a portion of FIG. 2 at A;

in the figure, 1 is a tank body, 10 is a containing groove, 2 is an aeration pipe, 20 is a mud-pressing plate, 21 is a rotary joint component, 211 is a joint, 212 is a plug plate, 213 is a socket plate, 214 is a bolt, 3 is a driving component, and 30 is a driving plate.

Detailed Description

The invention is shown in figures 1-3, and comprises a tank body 1, a plurality of aeration pipes 2 and a pair of driving components 3;

a plurality of aeration holes are formed in the aeration pipe 2, and a plurality of annular mud pressing plates 20 are fixedly connected to the outer wall of the aeration pipe 2;

two sides of the inner wall of the tank body 1 are provided with a circular accommodating groove 10 communicated with an external air source;

the driving assembly 3 comprises a motor and a driving plate 30, the driving plate 30 is disc-shaped and is accommodated in the accommodating groove 10, two ends of the aeration pipe 2 are respectively and fixedly connected in the driving plate 30 and communicated with the accommodating groove 10, and the motor is fixedly connected to the tank body and is used for driving the driving plate to rotate around the axis of the motor.

The outer wall of the driving plate 30 is provided with a fixedly connected sealing ring, and the inner wall of the accommodating groove is provided with a sealing groove for accommodating the sealing ring. The driving plate can freely rotate in the containing groove, and simultaneously, the excellent sealing effect is kept between the driving plate and the containing groove.

The bottom of the accommodating groove is provided with a plurality of pressure rods which are propped against the driving plate. Thereby supporting the driving plate and further avoiding water from leaking into the accommodating groove.

The end face, facing the bottom of the containing groove, of the driving plate 30 is provided with an annular protrusion which is coaxial with the driving plate, and the driving shaft of the motor extends into the containing groove and is communicated with the annular protrusion through a driving belt. The action of the driving component is more reasonable.

The mud pressing plate 20 comprises an inner plate and an outer plate, the outer plate is arranged along the axial direction of the aeration pipe and is sleeved outside the aeration pipe in an empty mode, and the inner plate is arranged along the radial direction of the aeration pipe and is fixedly connected between the inner wall of the aeration pipe and the inner wall of the outer plate. Thereby effectively blocking the sludge and avoiding the sludge from blocking the aeration holes.

The both ends of aeration pipe 2 all are connected with swivel joint subassembly 21, swivel joint subassembly 21 is including connecting 211, picture peg 212, socket plate 213 and an at least bolt 214, the end department at aeration pipe 2 is established to joint 211, picture peg 212 is the tube-shape, picture peg 212 fixed connection just stretches out to connecting 211 outside on the inner wall of joint 211, hold picture peg 213 fixed connection on aeration pipe 2's inner wall, and towards offering the annular slot with picture peg 212 adaptation on the terminal surface that connects 211, bolt 214 wears to establish the end department of aeration pipe and stretch into to the annular slot in, seted up on the outer wall of picture peg with the annular chute of bolt adaptation. The aeration pipe can freely rotate around the axis of the aeration pipe, and meanwhile, a good sealing effect is kept between the aeration pipe and the joint. Like this, when the aeration pipe moved to the bottom of the pool, the mud-pressing board will drive the aeration pipe rotation under the mud resistance effect to when stirring mud, avoiding blockking up, can ensure that mud is pressed under the mud-pressing board all the time.
