Especially, the foam will separate the raw materials and block the mixing of the raw materials, thereby affecting the quality of the product. INVENTION CONTENTS

[0004] To solve the technical problems in the background art, the utility model discloses a kind of water -based paint reaction kettle of splash-proof and anti-foam.

[0006] The peripheral wall of stirring cylinder is provided with a plurality of uniformly distributed flow guide holes arranged along the axial direction of stirring shaft;

[0007] The upper end of flow guide hole is provided with flow guide plate with flow guide effect;

[0008] When the stirring shaft rotates, the flow guide plate guides the liquid into the upper end inlet of the flow guide hole and flows out from the lower end outlet of the flow guide hole.

[0009] When the stirring shaft rotates, the flow guide plate pushes the liquid on the upper side in the reaction kettle to flow, and the liquid flows to the flow guide hole under the flow guide effect of the flow guide plate, and flows downward along the flow guide hole, enters the bottom position of the reaction kettle, so that the liquid at the stirring cylinder always flows downward, and does not impact the inner wall of the reaction kettle, thereby eliminating the phenomenon of liquid splashing, and foam is not generated, the production efficiency and quality of product are improved.

[0010] The liquid directly flows downward from the flow guide hole, the path is short, the flow rate is slow, and the mixing efficiency is low. Based on this, further improvement is that the channel in the flow guide hole is spiral. By such arrangement, the path of the liquid flowing in the flow guide hole is lengthened, and directional flow of the liquid is also achieved, and the flow rate is improved.

[0011] The spiral flow hole is directly processed into a spiral shape, which is difficult, and therefore two simplified structures are designed, the first structure is that a spiral shaft is inserted into the flow hole, and a spiral channel is formed between the outer wall of the spiral shaft and the inner wall of the flow hole.

[0012] The second structure is that a partition plate is inserted into the flow hole, and the partition plate is twisted into a spiral shape. The partition plate and the flow hole are fixed in the following three structures: 1, a welded pipe is inserted into the inner wall of the flow hole, the outer wall of the partition plate abuts against the inner wall of the welded pipe, the melting point of the welded pipe is lower than that of the stirring barrel and the partition plate, and the flow hole and the partition plate are fixed by brazing. This structure wastes more materials. 2, a plurality of straight welding rods are clamped on the inner wall of the flow hole, the outer wall of the partition plate abuts against the straight welding rods, the melting point of the straight welding rods is lower than that of the stirring barrel and the partition plate, and the flow hole and the partition plate are fixed by brazing. This structure has small contact area between the partition plate and the flow hole, low connection strength, and low utilization rate of the straight welding rods. 3, the outer wall of the partition plate is provided with a continuous spiral groove, and a spiral welding rod is embedded in the groove. This structure has the highest utilization rate of the spiral welding rod, the largest connection area between the partition plate and the flow hole, and the most stable structure.

[0013] The specific structure of the flow guide plate is that the flow guide plate is arc-shaped, and the opening direction of the flow guide plate is consistent with the rotating direction of the stirring shaft.

[0014] The beneficial effects of the present application are as follows: when the stirring shaft rotates, the flow guide plate pushes the liquid on the upper side of the reaction kettle to flow, the liquid flows to the flow hole under the guide of the flow guide plate, and then flows downward along the flow hole and enters the bottom position of the reaction kettle, so that the liquid at the stirring barrel always flows downward and does not impact the inner wall of the reaction kettle, thereby eliminating the phenomenon of liquid splashing and foam, and improving the production efficiency and quality of the product.

These drawings are not to scale and, in general, only provide an illustration of the principles of the application. They should not be taken to represent the only ways in which the present application could be implemented.

[0027] Example 1

[0028] As shown in Figure 1 and Figure 2 , the present application discloses a splash-proof and foam-proof water-based paint reaction kettle, which comprises a stirring shaft 1, and a cylindrical stirring cylinder 2 arranged at the lower end of the stirring shaft 1.

[0029] The peripheral wall of the stirring cylinder 2 is provided with a plurality of flow guide holes 3 which are uniformly distributed and arranged along the axial direction of the stirring shaft 1. The upper end of the flow guide hole 3, which is away from the center of the stirring cylinder 2, is provided with a notch, one end of which extends outwardly to form a flow guide plate 4. The flow guide plate 4 is arc-shaped and extends outwardly to protrude from the stirring cylinder 2 and is located close to the inner wall of the reaction kettle. The opening direction of the flow guide plate 4 is consistent with the rotation direction of the stirring shaft 1. When the stirring shaft 1 rotates, the flow guide plate 4 guides the liquid into the upper end inlet of the flow guide hole 3 and flows out from the lower end outlet of the flow guide hole 3.

[0030] The inner wall of the flow guide hole 3 is helical, which is used to prolong the flow path of the liquid and make the liquid flow in a certain direction, thereby improving the flow rate.

[0031] ​​Since the helical flow guide hole 3 is directly machined into a spiral shape, it is difficult, so a helical shaft 5 is inserted into the helical flow guide hole 3, and a helical channel is formed between the outer sidewall of the helical shaft 5 and the inner wall of the helical flow guide hole 3. The fixed mounting structure of the helical shaft 5 is that the helical shaft 5 includes a main shaft 51, and a helical fin 5 is connected to the outer side of the main shaft 51; the two ends of the main shaft 51 are connected and fixed to the hole wall of the helical flow guide hole 3 through connecting rods 53.

[0032] Compared with the prior art, the beneficial effects of the embodiment are that when the stirring shaft 1 rotates, the flow guide plate 4 pushes the liquid on the upper side in the reaction kettle to flow, and under the flow guiding effect of the flow guide plate 4, the liquid flows to the helical flow guide hole 3 and then flows downward along the helical flow guide hole 3 to the bottom position of the reaction kettle, so that the liquid at the stirring cylinder 2 always flows downward and does not impact the inner wall of the reaction kettle, thereby eliminating the phenomenon of liquid splashing and also eliminating the generation of foam, thereby improving the production efficiency and quality of the product.

[0033] Embodiment two:

[0034] Compared with embodiment one, the difference is that, as shown in Figure 6 and Figure 7 , a partition plate 6 is inserted into the helical flow guide hole 3; the partition plate 6 is twisted to form a helical shape and forms a helical channel with the hole wall of the helical flow guide hole 3. The specific mounting structure of the partition plate 6 is that a welded pipe 7 is inserted into the helical flow guide hole 3, and the outer sidewall of the partition plate 6 abuts against the inner wall of the welded pipe 7; the melting point of the welded pipe 7 is lower than that of the stirring cylinder 2 and the partition plate 6; and the helical flow guide hole 3 and the partition plate 6 are fixed by brazing.

[0035] Embodiment three:

[0036] Compared with embodiment two, the difference is that, as shown in Figure 8 and Figure 9 , a plurality of straight welding rods 8 are clamped to the inner wall of the helical flow guide hole 3; the outer wall of the partition plate 6 abuts against the straight welding rods 8; the melting point of the straight welding rods 8 is lower than that of the stirring cylinder 2 and the partition plate 6; and the helical flow guide hole 3 and the partition plate 6 are fixed by brazing.

[0037] Embodiment four:

[0038] Compared with embodiment two, the difference is that, as shown in Figures 3-5 , a continuous helical embedding groove 9 is arranged on the outer wall of the partition plate 6, and a helical welding rod is embedded in the embedding groove 9; the helical welding rod abuts against the inner wall of the helical flow guide hole 3. With this structure, the utilization rate of the helical welding rod is high, the connection area of the partition plate 6 and the helical flow guide hole 3 is large, and the structure is more stable.
