DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] As Figures 1 to 5 shown, the utility model provides a kind of flame retardant defoaming equipment, including outer sleeve 1, fixedly arranged with fixed pressing plate 2 on the outer wall of outer sleeve 1, and inner rotating shaft 3 is coaxially rotationally arranged in outer sleeve 1 by limiting structure, the bottom end of inner rotating shaft 3 protrudes the bottom of outer sleeve 1 setting, and the bottom end of inner rotating shaft 3 is fixedly connected with movable pressing plate 5 by inclined support 4, movable pressing plate 5 is arranged in parallel with fixed pressing plate 2, and inner rotating shaft 3 can drive movable pressing plate 5 surface and fixed pressing plate 2 surface contact.Limiting structure includes annular limiting groove 6 being opened on the inner wall of outer sleeve 1 and annular limiting block 7 being arranged on the outer wall of inner rotating shaft 3, and annular limiting block 7 rotationally embedded in annular limiting groove 6.

[0025] As Figure 1 shown, movable pressing plate 5 is connected by inclined support 4, which can make movable pressing plate 5 rotate smoothly to the position of being attached to fixed pressing plate 2 without interference, so as to clamp and break the foam. In this arrangement, there is an angle gap between fixed pressing plate 2 and movable pressing plate 5 at the initial position (i.e. before movable pressing plate 5 starts to rotate), and the foam in this gap is difficult to be collected by the rotation of movable pressing plate 5. Therefore, the position of the entire equipment can be adjusted after one rotation of movable pressing plate 5 for collection. That is, the foam in the reaction container can be broken in the full range by rotating movable pressing plate 5 twice.

[0026] In the present equipment, the bottom surface of movable pressing plate 5 and fixed pressing plate 2 is flush with the liquid surface, or slightly higher, so that the rotation of movable pressing plate 5 drives the synchronous movement of the foam for clamping and breaking.

[0027] For the setting of the movable pressing plate 5 and the fixed pressing plate 2 height, the outer wall of the outer sleeve 1 is provided with external threads, and the external threads are threadedly connected with a limiting sleeve 8. The outer wall of the outer sleeve 1 is linearly provided with a sliding groove 9 along the length direction of the outer sleeve 1, and the sliding groove 9 is slidably provided with an extension support 10.

[0028] As shown in Figure 3 , the inner wall of the sliding groove 9 is recessed to form a limiting vertical groove 11 on both sides, and the extension support 10 is slidably arranged in the limiting vertical groove 11 through a limiting piece (not shown in the figure).

[0029] The extension support 10 is used to be connected with the opening of the reaction container, and the pile body device is hung in the reaction container through the extension support 10, and the defoaming is performed by rotating the inner rotating shaft 3. And as another embodiment, the inner rotating shaft 3 is combined with the cover of the reaction container, and the defoaming of the reactant in a closed condition can also be realized.

[0030] The extension support 10 is connected with the port of the reaction container, and then the screw sleeve is spirally rotated, so that the setting height of the movable pressing plate 5 can be adjusted and positioned on the liquid surface. In addition, the extension support 10 can be prevented from being taken out of the sliding groove 9 through the connection of the limiting vertical groove 11 and the limiting piece.

[0031] As shown in Figure 1 , the end of the extension support 10 is provided with a clamping connector 12, the clamping connector 12 includes a first arc plate 13, a second arc plate 14 and an adjusting spring 15, the first arc plate 13 is fixedly arranged at the end of the extension support 10, the first arc plate 13 is connected with the second arc plate 14 through the adjusting spring 15, the second arc plate 14 is slidably arranged on the extension support 10, and the first arc plate 13 and the second arc plate 14 form a clamping gap with adjustable width.

[0032] The clamping gap can be adjusted by the extension and retraction of the adjusting spring 15, so as to adapt to reaction containers with different wall thicknesses, so that the flexibility of the defoaming device is higher. And as shown in Figure 1 , a cover body can also be arranged on the first arc plate 13 to frame the second arc plate 14 and the adjusting spring 15, so as to play a protection role.

[0033] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application, and the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements shall also be considered to fall within the protection scope of the present application.
