[0024] As shown in Figure 1 、 Figure 2 , the end face of the support plate 5 is welded with a reinforcing plate 8, the other straight angle side of the reinforcing plate 8 is welded with the buffer tank 1, through the setting of the reinforcing plate 8, the support plate 5 can be assisted and reinforced for use, the surface of the sleeve 6 is provided with a flow-through hole 9, the flow-through hole 9 is located in the inside of the working liquid 3, through the setting of the flow-through hole 9, the normal flow of fluid can be guaranteed.

[0025] As shown in Figure 1 、 Figure 3 、 Figure 4 , the sleeve 6 is provided with a defoaming mechanism 11, the defoaming mechanism 11 is contacted with the foam 4, the outer side of the sleeve 6 is fixedly sleeved with a support disc 110, the outer side of the sleeve 6 is movably sleeved with a large gear 111, the large gear 111 is contacted with the support disc 110, the lower side of the large gear 111 is fixedly connected with a mounting bracket 112, the horizontal part of the mounting bracket 112 is fixedly installed with an ultrasonic defoamer 113, the outer side of the sleeve 6 is fixedly sleeved with a mounting plate 114, the upper end of the mounting plate 114 is fixedly installed with a waterproof motor 115, the output shaft of the waterproof motor 115 is rotatably connected with the mounting plate 114, the surface of the large gear 111 is provided with an annular groove 117, the lower end of the mounting plate 114 is bonded with an elastic rod 118, the other end of the elastic rod 118 is bonded with a limit ball 119, the limit ball 119 is slidably connected with the annular groove 117, through the setting of the waterproof motor 115, the large gear 111 and other structures, the ultrasonic defoamer 113 can be rotated to ultrasonic eliminate the foam 4.

[0026] like Figure 1 , Figure 3 , Figure 4 As shown, there are two mounting brackets 112, which are symmetrically distributed on the large gear 111. The ultrasonic defoamer 113 can be installed and used through the mounting brackets 112. A small gear 116 is fixedly sleeved on the outside of the output shaft of the waterproof motor 115. The small gear 116 meshes with the large gear 111. Through the meshing relationship, when the small gear 116 rotates, it can drive the large gear 111 to rotate. There are two limit balls 119, which are symmetrically distributed on the large gear 111. The limit balls 119 can cooperate with the annular groove 117 to perform rotation limit treatment.

[0027] The specific implementation process of this utility model is as follows: By setting the support plate 5, the sleeve 6 can be welded and fixed, so that the sleeve 6 is located inside the buffer tank 1 and the bottom of the sleeve 6 does not touch the bottom. Under the action of the reinforcing plate 8, the support plate 5 can be reinforced to ensure the stability of the sleeve 6. When the bath liquid enters the buffer tank 1, since there is an exhaust hole 10 at the top of the sleeve 6, the bath liquid inside it is level with the liquid level of the buffer tank 1. However, the foam 4 formed by the impact cannot enter it, so that it cannot affect the liquid level gauge 7's detection of the liquid level, thus achieving a good monitoring and anti-interference effect.

[0028] The waterproof motor 115 drives the output shaft to rotate the pinion 116. In the meshing relationship, the pinion 116 drives the large gear 111 to rotate, which in turn drives the mounting bracket 112 to rotate. When the mounting bracket 112 rotates, it can drive the ultrasonic defoamer 113 to rotate. Under the action of the ultrasonic defoamer 113, the foam 4 can be ultrasonically eliminated to avoid the monitoring impact caused by the foam 4 and improve the monitoring efficiency. When the large gear 111 rotates, the limiting ball 119 can slide along the surface of the annular groove 117 to guide the rotation of the large gear 111. Under the deformation of the elastic rod 118, the limiting ball 119 can be well contacted and limited, thereby ensuring the rotational stability of the large gear 111.

[0029] The sleeve 6 is welded and fixed through the support plate 5, so that the sleeve 6 is located in the inside of the buffer tank 1, and the bottom of the sleeve 6 does not touch the bottom; when the bath liquid enters the buffer tank 1, the bath liquid is level with the liquid level of the buffer tank 1 in the inside of the sleeve 6 due to the exhaust hole 10 at the top of the sleeve 6, but the foam 4 formed by impact cannot enter the inside, so that the foam 4 cannot affect the detection operation of the liquid level meter 7 on the liquid level, so that good monitoring anti-interference effect is achieved; the waterproof motor 115, the pinion 116, the gear wheel 111 and the like are used in cooperation to drive the mounting frame 112 to rotate the ultrasonic defoaming device 113 to perform ultrasonic elimination operation on the foam 4, so that the monitoring influence caused by the foam 4 is avoided, the monitoring efficiency is improved, and the gear wheel 111 is guided to rotate under the annular groove 117, the limiting ball 119 and the like, so that the rotation stability of the gear wheel 111 is ensured.
