[0009] Several insert plates are fixedly installed on the inner wall of the defoaming plate, and each insert plate also has a threaded hole on one side.

[0010] The height of the insert plate is adapted to the height of the inner hole of the fixing ring;

[0011] When the insert plate is inserted into the first annular groove, the threaded hole on the insert plate corresponds to the threaded hole on the fixing ring, and the insert plate and the fixing ring are connected by bolts.

[0012] In a preferred embodiment, the present invention can be further configured such that the defoaming board comprises four arc-shaped boards of the same shape, and each arc-shaped board has a plurality of water drainage holes on one side.

[0013] In a preferred embodiment, the present invention can be further configured such that: two first through holes are symmetrically opened on one side of each of the arc-shaped plates, and the bottom of the two first through holes penetrates the end of the short arc-shaped edge of the annular plate;

[0014] The insert plate is fixedly mounted on the corresponding first through hole.

[0015] In a preferred embodiment, the present invention can be further configured such that: a support block is provided on the top of the insert plate, and one side of the support block is fixed to one side of the corresponding arc-shaped plate.

[0016] In a preferred embodiment, the present invention can be further configured such that each of the arc-shaped plates is provided with a plurality of bubble-breaking rods;

[0017] Each of the arc-shaped rods has several threaded through holes on one side, and the bubble-breaking rod passes through the corresponding threaded through hole, and the bubble-breaking rod is threadedly connected to the corresponding threaded through hole;

[0018] The end of the bubble-breaking rod furthest from the liquid outlet is designed to be pointed.

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] 1. By installing a defoaming plate on the inner rotor, which can be detachably connected to the inner rotor, it is convenient for operators to maintain or replace the defoaming plate, simplifying the maintenance process.

[0021] 2. By installing bubble-breaking rods on the curved plate, the speed of foam breaking is further accelerated.

[0022] 3. By setting a support block on the top of the insert plate, the support block further strengthens the strength of the defoaming board. Attached Figure Description
