Description

Technical Field

[0001] The utility model belongs to the technical field of resin processing, and particularly relates to an anti-foaming device for a reaction kettle in resin production. Background Art

[0002] Resin is a kind of polymer, which is in a solid or semi-solid state at normal temperature, softens or melts when heated, and can flow under the action of external force. Resin processing usually includes pretreatment, molding and post-treatment. Pretreatment may involve the mixing of resin solution and additives, and bubbles are likely to appear during the mixing and stirring process. If the bubbles are not treated, the bubbles will cause surface defects such as pinholes, protrusions or depressions after the resin is cured, seriously affecting the appearance quality of the product. In occasions where pressure needs to be borne, the bubbles may become potential weaknesses, resulting in fractures or damages during the use of the product. The existence of bubbles will also destroy the structural integrity of the resin, thereby reducing its tensile strength, compressive strength and hardness. In addition, the bubbles will cause the density of the resin to decrease, thereby affecting its heat resistance and chemical corrosion resistance. In some existing technologies, during the stirring of the resin solution, defoaming treatment is carried out, and the bubbles in the resin solution are pricked by defoaming needles arranged on the stirring shaft. Multiple defoaming needles in the above manner are fixedly connected to the stirring shaft, and the defoaming needles move along with the stirring shaft, lacking flexibility. In terms of defoaming efficiency, the action range of the defoaming needles is limited, resulting in low defoaming efficiency. At the same time, the stirring effect on the resin solution is limited, and the help provided for the stirring effect is limited, thus resulting in poor mixing efficiency. Therefore, the utility model provides an anti-foaming device for a reaction kettle in resin production. Summary of the Utility Model

[0003] Aiming at the problem of low defoaming efficiency in the prior art, the utility model provides an anti-foaming device for a reaction kettle in resin production.

[0004] The utility model adopts the following technical scheme: an anti-foaming device for a reaction kettle in resin production, which includes a shell and a stirring component installed inside the shell. The stirring component includes a driving shaft rotatably connected to the shell. A plurality of stirring shafts are fixedly connected to the outer surface of the driving shaft. A set of defoaming components are arranged on the stirring shafts. The defoaming components include steel wire ropes, and one end of each steel wire rope is fixedly connected with a defoaming ball;

[0005] The stirring component is assembled to uniformly stir the resin solution through the rotating stirring shaft in cooperation with the defoaming component, ensuring the full mixing of the resin and the curing agent, and avoiding problems such as incomplete local curing or uneven performance;

[0006] The defoaming component is assembled to cooperate with the stirring component during the stirring process, so that the steel wire rope pulls the defoaming ball to move in the resin solution, not only promoting the mixing of the resin and the curing agent, but also synchronously eliminating bubbles, ensuring the uniformity of the resin system.

[0007] Preferably, the stirring assembly further includes a driving motor fixedly installed at the top of the housing. The output end of the driving motor is fixedly connected to the top end of the driving shaft, and the bottom end of the driving shaft is rotatably connected to the inner wall of the bottom of the housing. The stirring shafts are arranged in a staggered manner.

[0008] Preferably, one end of the steel wire rope is rotatably sleeved on the stirring shaft, and the defoaming ball is fixedly connected to the end of the steel wire rope away from the stirring shaft.

[0009] Preferably, the defoaming ball includes a counterweight ball fixedly connected to the end of the steel wire rope away from the stirring shaft, and a bubble-absorbing cotton net is arranged outside the counterweight ball.

[0010] Preferably, defoaming needles are fixedly connected to the surface of the counterweight ball, and the defoaming needles penetrate through the bubble-absorbing cotton net.

[0011] Preferably, the defoaming needles are arranged in an S shape.

[0012] Beneficial effects:

[0013] (1) For the defoaming device for a reaction kettle used in resin production of the present utility model, through the cooperation of the stirring assembly and the defoaming assembly, the stirring shaft drives the steel wire rope and the defoaming ball to move, which not only promotes the mixing of the resin and the curing agent, but also can synchronously eliminate bubbles, ensuring the uniformity of the resin system. The defoaming ball swings with the steel wire rope during the stirring process, expanding the action range of the defoaming needles, further improving the bubble removal efficiency. The defoaming ball and the defoaming needles stir the resin from multiple directions during the stirring process, enhancing the stirring effect and shortening the mixing time.

[0014] (2) For the defoaming device for a reaction kettle used in resin production of the present utility model, the flexible design of the steel wire rope and the defoaming ball can adapt to resins with different viscosities, ensuring stable defoaming effect. The swinging characteristics of the defoaming ball enable it to better adapt to containers with complex shapes, improving the applicability. The streamline design of the S-shaped defoaming needles can reduce the resistance when moving in the resin and increase the contact route with the resin, thereby reducing the interference with the resin flow and the possibility of bubble generation.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] Example: Figures 1 - 4 A defoaming device for a reactor used in resin production is shown, comprising a shell 1 and a stirring assembly 2 installed inside the shell 1, the stirring assembly 2 comprising a driving shaft 22 rotatably connected to the shell 1, a plurality of stirring shafts 23 are fixedly connected to the outer surface of the driving shaft 22, a group of defoaming assemblies 3 are arranged on the stirring shaft 23, the defoaming assemblies 3 comprise a steel wire rope 31, a defoaming ball 32 is fixedly connected to one end of the steel wire rope 31; the stirring assembly 2 is configured to achieve uniform stirring of the resin solution by cooperating with the defoaming assembly 3 through the rotating stirring shaft 23, so as to ensure that the resin and the curing agent are fully mixed, and avoid problems such as incomplete local curing or uneven performance; the defoaming assembly 3 is configured to cooperate with the stirring assembly 2 during the stirring process, so that the steel wire rope 31 pulls the defoaming ball 32 to move in the resin solution, which not only promotes the mixing of the resin and the curing agent, but also synchronously eliminates bubbles, so as to ensure the uniformity of the resin system.

[0022] In this embodiment, the stirring component 2 is started so that the driving motor 21 drives the driving shaft 22 to rotate, thereby causing the stirring shaft 23 fixedly connected to the driving shaft 22 to rotate synchronously to stir and mix the resin solution. During the stirring process, when the stirring shaft 23 rotates with the driving shaft 22 as the center, a plurality of defoaming balls 32 suspended on the stirring shaft 23 are pulled along with the wire rope 31, which can promote the mixing of the resin and the curing agent while also eliminating bubbles synchronously. The defoaming balls 32 can swing along with the wire rope 31, thereby expanding the range of action of the defoaming needle 323 and further improving the defoaming efficiency.

[0023] like Figure 1 and Figure 2 As shown, the stirring assembly 2 also includes a driving motor 21 fixedly mounted on the top of the shell 1, the output end of the driving motor 21 is fixedly connected to the top of the driving shaft 22, the bottom end of the driving shaft 22 is rotatably connected to the bottom inner wall of the shell 1, and the stirring shaft 23 is staggered; one end of the wire rope 31 is rotatably sleeved with the stirring shaft 23, and the defoaming ball 32 is fixedly connected to the end of the wire rope 31 away from the stirring shaft 23.

[0024] In this embodiment, the drive motor 21 drives the drive shaft 22 to rotate inside the housing 1, and at the same time makes a plurality of stirring shafts 23 fixedly connected to the drive shaft 22 rotate synchronously. When the stirring shaft 23 rotates, it takes the drive shaft 22 as the center of the circle. When the defoaming ball 32 rotates, it swings along with the steel wire rope 31. One end of the steel wire rope 31 away from the defoaming ball 32 is sleeved on the stirring shaft 23. When the stirring shaft 23 rotates, the defoaming ball 32 displaces during rotation, and one end of the steel wire rope 31 sleeved on the stirring shaft 23 rotates on the stirring shaft 23. The rotation angle of the steel wire rope 31 is affected by the rotation speed of the drive shaft 22 and the viscosity of the resin solution. The flexible design of the steel wire rope 31 enables the defoaming ball 32 to swing along with the steel wire rope 31 during the stirring process, and the rotation angle of a single steel wire rope 31 may also change during rotation. Therefore, the action range of the defoaming ball 32 can be expanded, and the resin solution can be more fully mixed and defoamed in cooperation with the staggered stirring shafts 23.

[0025] As Figure 3 and Figure 4 shown, the defoaming ball 32 includes a counterweight ball 321 fixedly connected to one end of the steel wire rope 31 away from the stirring shaft 23, and a bubble-absorbing cotton net 322 is arranged outside the counterweight ball 321; a defoaming needle 323 is fixedly connected to the surface of the counterweight ball 321, and the defoaming needle 323 penetrates through the bubble-absorbing cotton net 322; the defoaming needle 323 is arranged in an S shape.

[0026] In this embodiment, during stirring, the defoaming ball 32 swings along with the steel wire rope 31. The defoaming ball 32 includes a solid counterweight ball 321 fixedly connected to the steel wire rope 31. The solid counterweight ball 321 is coated with a bubble-absorbing cotton net 322. Through its porous structure, the bubble-absorbing cotton net 322 can effectively adsorb the bubbles in the resin, reduce the bubble residue, help the resin flow more smoothly, reduce the flow resistance caused by bubble accumulation. At the same time, a plurality of S-shaped defoaming needles 323 are evenly arranged on the spherical surface of the counterweight ball 321. The defoaming needles 323 penetrate through the bubble-absorbing cotton net 322 and contact the resin solution. When the defoaming ball 32 swings during stirring, the defoaming needles 323 can pierce the bubbles in the resin solution, making it easier to discharge. On the one hand, the S-shaped defoaming needles 323 can stir the resin solution more evenly, disperse the bubbles more uniformly, and avoid local bubble accumulation. On the other hand, its streamlined design can reduce the resistance during movement in the resin, thereby reducing the interference with the resin flow and reducing the possibility of bubble generation, while increasing the chance of contact between the bubbles and the defoaming needles 323, thereby improving the efficiency of bubble capture and elimination.

[0027] Working principle: When in use, start the stirring assembly 2, so that the driving shaft 22 drives the stirring shaft 23 to rotate in the housing 1. When the stirring shaft 23 rotates with the driving shaft 22 as the center, the defoaming ball 32 moves in the resin solution along with the steel wire rope 31. When the defoaming ball 32 rotates with the stirring shaft 23, it can also stir the resin solution. Multiple stirring shafts 23 cooperate with the defoaming ball 32 to stir the resin solution during stirring, enhancing the stirring effect, making the mixing of the resin solution and the curing agent more uniform. When the defoaming ball 32 moves in the resin solution, the defoaming needle 323 pierces or cuts the bubbles in the resin solution, making it easier to discharge from the resin solution. The flexible design of the steel wire rope 31 enables the defoaming ball 32 to flexibly adapt when dealing with resin solutions of different viscosities. The S-shaped defoaming needle 323 can reduce the resistance during movement in the resin. The design of the defoaming needle 323 at multiple angles enables the resin solution to be stirred from multiple directions during the stirring process, enhancing the stirring effect. Stirring and defoaming are carried out simultaneously, reducing the energy consumption of the separate defoaming step and improving the processing efficiency.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
