Description

Technical Field

[0001] The utility model relates to a defoaming device inside a reaction kettle. Background Art

[0002] During the production process, chemical additives will produce bubbles due to chemical reactions, which will continuously produce foam on the surface of the liquid.

[0003] Currently, defoaming generally adopts the natural overflow method, that is, after the reaction is completed, the mother liquor is slowly released from the bottom, and the foam on the surface is retained. This method not only requires the overflow to be opened after the reaction is complete, but also because the foam will accumulate more and more during the reaction, the amount of foam will be large, causing a large amount of raw material loss (the foam is also formed by the aeration of the mother liquor). Utility Model Content

[0004] The utility model aims to solve the above problems in the prior art and proposes a defoaming device for the inside of a reactor. The defoaming mechanism, namely a displacement assembly, a grille assembly and a wire mesh assembly, is arranged on the end cover of the reactor. When the reactor bag cover is installed, the displacement assembly moves up and down to contact the liquid inside the reactor, and the grille assembly and the wire mesh assembly touch the floating foam to break it and eliminate it.

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0024] like Figure 1-2 As shown, a defoaming device inside a reactor is characterized in that it comprises:

[0025] Reactor end cover 1;

[0026] A defoaming mechanism connected below the reactor end cover 1;

[0027] The defoaming mechanism comprises a wire mesh assembly, a grille assembly and a displacement assembly. The upper end of the displacement assembly is fixed on the reactor end cover 1, the lower end of the displacement assembly is connected to the grille assembly, and the wire mesh assembly is connected to the grille assembly.

[0028] Furthermore, the edge of the reactor end cover 1 is provided with a sealing ring.

[0029] Furthermore, a lock buckle is connected to the reactor end cover 1.

[0030] Furthermore, the displacement assembly comprises:

[0031] A displacement cylinder 2, which is fixed to the upper end of the reactor end cover 1 and whose telescopic rod 21 passes through the reactor end cover 1 and extends downward;

[0032] A bearing 22 is provided at the connection between the displacement cylinder 2 and the reactor end cover 1, and a gear 23 is sleeved on the bearing 22. A rotating motor 11 is provided on the reactor end cover 1 on one side of the gear 23, and its output end is meshed with the gear 23 for power connection.

[0033] Furthermore, the grille assembly comprises:

[0034] The grid plate 3 is in the shape of a disk and has a plurality of uniform grids 31 on its surface;

[0035] The grid plate 3 has a connecting hole 33 in the middle thereof for connecting the telescopic rod 21 of the displacement cylinder 2 , and the grid plate 3 is provided with a plurality of defoaming needles 32 .

[0036] Furthermore, the wire mesh assembly comprises:

[0037] The screen 4 is coated on the upper and lower sides of the grid plate 3, and the screen 4 is composed of densely woven stainless steel wires.

[0038] In the above structure, the reactor end cover 1 is first installed on the reactor. After the liquid in the reactor reacts, foam is generated. The grid assembly and the wire mesh assembly are moved down to the surface of the liquid by the displacement cylinder 2 to continue to sink. The foam is punctured by the defoaming needle 32 on the grid plate 3 to eliminate the foam. At the same time, the rotating motor 11 drives the displacement cylinder 2 connected to the gear 23 to rotate it, so that the displacement cylinder 2 rotates as a whole, and the grid and the screen 4 on the telescopic rod 21 rotate. The densely woven screen 4 constantly contacts the foam, and the foam is removed by rotation. After the foam is eliminated, the raw materials remaining on the screen 4 can be dissolved in the liquid by downward infiltration. This device quickly removes the foam through the defoaming needle 32 and the screen 4 coordinated with the rotating motor 11, and the effect is good without any loss of raw materials.
