In particular, the pump is an indispensable electromechanical device in the electroplating industry; for example, a liquid pump is used for pumping the electroplating solution and enabling the electroplating solution to form a circulating pumping between the temporary storage container and the electroplating bath, so that the electroplating solution is conveniently pumped out and filtered at the end of the temporary storage container (foreign matters on a workpiece enter the electroplating solution, such as dust, rust and the like, need to be filtered and disposed from the electroplating solution, and then deposited metal salts in the electroplating solution or crystals of the metal salts need to be filtered and disposed in the electroplating solution), and corresponding chemical agents are added into the temporary storage container at intervals to maintain the concentration ratio of various chemical agent components in the electroplating solution, so that the electroplating quality of the workpiece is ensured. In the circulation process of the plating solution, a large amount of foam is inevitably generated in the temporary storage container due to liquid impact generated during pumping or the backflow of the plating solution, and in order to eliminate the generated foam, a defoaming pump is often required to be arranged in the temporary storage container of the plating solution.

The driving device 1 in this embodiment is a motor, that is, when the driving device 1 drives the defoaming assembly 2 and the liquid pumping assembly 3 to work, the liquid pumping assembly 3 located below the liquid level pumps the electroplating solution to a corresponding position (such as an electroplating bath), and the defoaming assembly 2 located at the liquid level defoams the foam floating on the liquid level.

As shown in fig. 2-4, in a preferred embodiment, the defoaming assembly 2 includes a first housing 21, a first impeller 22 and a transmission shaft 23, a first accommodating cavity (not shown) is disposed in the first housing 21, the first impeller 22 is located in the first accommodating cavity, the first impeller 22 is connected to the transmission shaft 23, the transmission shaft 23 is in transmission connection with the driving device 1, and the first housing 21 is fixedly connected to the driving device 1; the bottom of the first casing 21 is further provided with a first through hole 24, the first casing 21 is further provided with a second through hole 25 along the peripheral side thereof, and the first through hole 24 and the second through hole 25 are both communicated with the accommodating cavity. Further, the first impeller 22 includes a wheel seat 221 and a plurality of blades 222, the blades 222 are fixed on one surface of the wheel seat 221 in an injection molding manner, a skirt 223 is further surrounded on the other surface of the wheel seat 221 opposite to the blades 222, in the axial direction, one end of the skirt 223 and the wheel seat 221 are integrally molded in an injection molding manner, and the other end is a free end and extends in a direction away from the wheel seat 221. Specifically, the skirt 223 is annular, and the outer diameter of the skirt 223 is not greater than the outer diameter of the wheel seat 221, in this embodiment the outer diameter of the skirt 223 is the same as the outer diameter of the wheel seat 221, that is, the skirt 223 is circular, and the outer diameter of the skirt 223 is not greater than the outer diameter of the wheel seat 221; the skirt 223 is arranged to increase the thickness of the first impeller 22 as a whole, so that the blades 222 in the first impeller 22 can be immersed into the working fluid to the maximum extent on the original basis, and the working fluid can be more sufficiently thrown out by the impeller 2 and the foam is broken (defoamed), thereby ensuring the defoaming efficiency; meanwhile, the skirt 223 is arranged to increase the height of the top of the first impeller 22, so that the working fluid can be prevented from entering between the joint of the transmission shaft 23 and the first housing 21, causing corrosion of a bearing or corrosion of the working fluid due to leakage of the working fluid or influencing the stable and reliable operation of the driving device 1.

Furthermore, on the horizontal or transverse projection plane, at least part of the blade 222 of the impeller is overlapped with the second through hole 25, and the height of the skirt 223 is higher than that of the second through hole 25, which is beneficial for the working fluid to be sent out from the second through hole 25, and simultaneously reduces the probability of submerging the skirt 223 due to the factors such as the fluctuation of the liquid level of the working fluid. Specifically, when the first impeller 22 rotates, a centrifugal force is generated, and under the action of the centrifugal force, the liquid to be treated enters from the first through hole 24 and is rapidly thrown out from the second through hole 25, so as to break the foam; alternatively, the foam may be directly introduced into the defoaming assembly, and the bubbles in the foam may be destroyed by the shearing force generated when the first impeller 22 rotates at a high speed.
