Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water reducer reaction kettles, in particular to a water reducer reaction kettle with a defoaming structure. Background Art
[0002] A water reducer reactor is a device used to produce water reducers. During the production process, different materials, such as retarders, air entraining agents, and thickeners, need to be added for compounding. To avoid inhomogeneity during compounding, stirring is currently the most common method used to disperse the various components in the reactor.
[0003] Water reducers are anionic surfactants containing polyoxyethylene side chains in their molecular structure. They are prone to foaming during mixing, and the air-entraining agent added during compounding can also easily generate foam, potentially causing the liquid to escape from the reactor. The presence of large amounts of foam in the liquid can lead to problems such as insufficient pump pressure or inefficient discharge and transport. Therefore, foam removal is necessary. Traditionally, defoaming of water reducer reactors is achieved by adding defoamers. However, this addition can affect various performance characteristics of the water reducer. To address this issue, we have proposed a water reducer reactor with a defoaming mechanism. Utility Model Content

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0021] The utility model provides a technical solution: Figures 1-4 As shown, in this embodiment, a water reducer reactor with a defoaming structure includes a kettle body 1, the top and bottom of the kettle body 1 are fixedly connected with a kettle cover 2 and a kettle support 3 respectively, the top of the kettle cover 2 is fixedly connected with a feed port 4, and one side of the kettle support 3 is fixedly connected with a discharge port 5, a sieve plate 12 is slidably connected between the inner walls of the kettle body 1, and a lifting component is provided inside the kettle body 1, which is used to drive the sieve plate 12 to move, and a rotating shaft 16 is rotatably connected to the bottom of the inner wall of the kettle support 3, and a stirring scraper 17 is fixedly connected to the outside of the rotating shaft 16, and an electric heater 15 is fixedly installed above the stirring scraper 17 and between the inner walls of the kettle body 1, and a power motor 7 is fixedly installed at the bottom of the kettle support 3, and the output end of the power motor 7 extends to the interior of the kettle support 3 and is fixedly connected to the rotating shaft 16, and a microporous screen 13 is provided inside the sieve plate 12.
[0022] When using a water reducer reactor to produce water reducer, first, the water reducer is introduced into the reactor through the feed port 4 on the top of the reactor cover 2, and the raw material mixture does not pass through the sieve plate 12. Then, the power motor 7 is used to drive the raw materials inside the reactor to be fully mixed and stirred. During the stirring process, a large amount of foam will be generated inside the water reducer. At this time, the electric heater 15 is started to heat the water reducer. The heating can promote the rapid evaporation and release of bubbles in the water reducer, thereby reducing the surface tension of the liquid, destroying the bubbles and achieving a defoaming effect. At the same time, the lifting component is used to drive the sieve plate 12 to move between the inner walls of the kettle body 1, so as to facilitate the removal of foam inside and outside the water reducer, further improving the defoaming effect.
[0023] like Figures 1-4As shown, the lifting assembly includes a first slide 8 and a second slide 10, a threaded rod 9 is rotatably connected between the inner walls of the first slide 8, and the outer side of the threaded rod 9 is threadedly connected to the first lifting block 18, the first lifting block 18 is fixedly connected to the sub-screen plate 12, an auxiliary rod 11 is fixedly connected between the inner walls of the second slide 10, and the outer side of the auxiliary rod 11 is slidably connected to the second lifting block 19, the sub-screen plate 12 is fixedly connected to the second lifting block 19 on the side away from the first lifting block 18, a servo motor 6 is fixedly installed on the top of the kettle body 1, and the output end of the servo motor 6 extends to the interior of the first slide 8 and is fixedly connected to the threaded rod 9, and the bottom of the inner walls of the first slide 8 and the second slide 10 are both provided with an inclined surface structure 14, and the inclined surfaces of the two inclined surface structures 14 are respectively fitted with the bottom surfaces of the first lifting block 18 and the second lifting block 19.
[0024] The threaded rod 9 is driven by the servo motor 6 to rotate between the inner walls of the first chute 8, and the slave belt drives the sub-screen plate 12 through the first lifting block 18 to move smoothly between the inner walls of the kettle body 1 under the assistance of the auxiliary rod 11, and then moves through the sub-screen plate 12, so that the microporous screen 13 inside the sub-screen plate 12 removes the foam inside and outside the water reducer, which is further beneficial to improve the defoaming effect of the water reducer.
[0025] When using a water reducer reactor to produce water reducer, first, the water reducer is introduced into the reactor through the feed port 4 on the top of the reactor cover 2, and the raw material mixture does not pass through the sieve plate 12. Then, the power motor 7 is used to drive the raw materials inside the reactor to be fully mixed and stirred. During the stirring process, a large amount of foam will be generated inside the water reducer. At this time, the water reducer is heated by starting the electric heater 15. The heating can cause the bubbles in the water reducer to evaporate and release quickly. At the same time, the servo motor 6 is used to drive the threaded rod 9 to rotate between the inner walls of the first slide 8. The belt drives the sieve plate 12 to move smoothly between the inner walls of the kettle body 1 under the assistance of the auxiliary rod 11 through the first lifting block 18, and then moves through the sieve plate 12, so that the microporous screen 13 inside the sieve plate 12 takes the foam inside and outside the water reducer away from the water reducer body.
[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
