Description

Technical Field

[0001] This utility model relates to the field of resin processing technology, specifically to a demulsification device for resin production that improves water washing efficiency. Background Technology

[0002] Resin refers to an organic polymer that typically softens or melts when heated. When softened, it tends to flow under external force. At room temperature, it is mostly solid, semi-solid, or pseudo-solid, and sometimes it can also be liquid. During the resin production process, emulsions are often formed. Emulsions have high stability, and without demulsification treatment, water and resin are difficult to separate effectively.

[0003] Traditional resin production demulsification methods often employ static stratification or simple mechanical stirring. However, static stratification is time-consuming and affects production efficiency, while simple mechanical stirring results in a limited flow state of the emulsion, making it difficult to achieve complete breakage of the emulsion and separation of oil and water. This leads to incomplete removal of impurities during subsequent water washing, affecting the purity and performance of the resin. Utility Model Content

[0010] Preferably, the material conveying structure includes a motor, which is fixedly installed on the upper surface of the inner reaction cylinder.

The housing and the outer reaction cylinder are connected by a discharge pipe. A valve is installed inside the discharge pipe. A square through hole is provided on the front surface of the housing.

[0019] 1. This device is equipped with an outer reaction cylinder and an inner reaction cylinder to form a double-layer reaction structure. Both the outer and inner reaction cylinders are hollow double-layer structures with interconnected interlayers.

[0021] 3. This device has a box below the outer reaction cylinder, and a filter box with a filter screen is slidably installed inside the box. The emulsion after the reaction is filtered through the filter screen to intercept flocculent matter or impurities that have not been completely demulsified, thereby reducing the content of liquid impurities entering the water washing stage and improving the subsequent water washing efficiency of the resin.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a demulsifying device for resin production that improves water washing efficiency, including an outer reaction cylinder 1, a feed pipe 2, an inner reaction cylinder 3, a steam inlet pipe 4, a steam outlet pipe 5, a through pipe 6, a motor 7, a drive rod 8, a conveying plate 9, a stirring rod 10, a box 11, a discharge pipe 12, a filter box 13, and a liquid outlet pipe 14.

[0031] The outer reaction cylinder 1 is a hollow double-layer structure. A feed pipe 2 is installed through the upper surface of the outer reaction cylinder 1. A valve is installed inside the feed pipe 2. An inner reaction cylinder 3 is installed through the upper surface of the outer reaction cylinder 1. The inner reaction cylinder 3 is a hollow double-layer structure. The hollow interlayers of the outer reaction cylinder 1 and the inner reaction cylinder 3 are interconnected. A circular through hole is provided on the lower surface of the inner reaction cylinder 3. A steam inlet pipe 4 is installed through the side surface of the outer reaction cylinder 1. A steam outlet pipe 5 is installed through the other side surface of the outer reaction cylinder 1. Both the steam inlet pipe 4 and the steam outlet pipe 5 are inserted into the hollow interlayer of the outer reaction cylinder 1. The outer reaction cylinder 1 and the inner reaction cylinder 3 together constitute a double-layer reaction structure. The double-layer reaction structure increases the reaction efficiency by separating the reaction area inside the outer reaction cylinder 1 through the inner reaction cylinder 3.

[0032] like Figure 1 , Figure 2 and Figure 6 As shown, when using this device, the valve of the feed pipe 2 is opened, and the mixture of resin emulsion and demulsifier is injected into the inner reaction cylinder 3 through the feed pipe 2. Steam is introduced into the jacket of the outer reaction cylinder 1 through the steam inlet pipe 4. The steam enters the jacket of the inner reaction cylinder 3 along the through jacket and is finally discharged from the steam outlet pipe 5. The steam is used to heat the inner reaction cylinder 3 and the outer reaction cylinder 1, increasing the reaction efficiency of the materials. The double-layer jacket structure of the outer reaction cylinder 1 and the inner reaction cylinder 3 forms a uniform heating space, improving the stability of the reaction temperature.

[0033] A through-pipe 6 is installed through the surface of the inner reaction cylinder 3. A one-way valve is installed inside the through-pipe 6. The direction of the one-way valve of the through-pipe 6 is from the inner reaction cylinder 3 to the outer reaction cylinder 1. Six through-pipes 6 are arranged equidistantly in a ring on the surface of the inner reaction cylinder 3. A material conveying structure is installed inside the inner reaction cylinder 3. The material conveying structure realizes the vertical conveying of materials inside the inner reaction cylinder 3 through the conveying plate 9 to increase the reaction efficiency of the materials. The material conveying structure includes a motor 7, which is fixedly installed on the upper surface of the inner reaction cylinder 3. The output end of the motor 7 is fixedly connected to a drive rod 8. The drive rod 8 is located inside the inner reaction cylinder 3 and is inserted into the inner reaction cylinder 1 through the circular through hole at the lower end of the inner reaction cylinder 3. A conveying plate 9 is fixedly installed on the outer surface of the drive rod 8 located in the inner reaction cylinder 3. The conveying plate 9 has a spiral structure. A stirring rod 10 is fixedly installed on the outer surface of the drive rod 8 located in the outer reaction cylinder 1. The stirring rod 10 has the same shape as the inner wall of the outer reaction cylinder 1. Four stirring rods 10 are arranged equidistantly in a ring on the outer surface of the drive rod 8.

[0034] like Figure 3 , Figure 4 and Figure 6 As shown, during the material reaction process, the motor 7 is started, and the motor 7 drives the drive rod 8 to rotate. The rotating drive rod 8 drives the conveying plate 9 and the stirring rod 10 on the surface to rotate synchronously. The rotating spiral conveying plate 9 pushes the bottom material upward spirally inside the inner reaction cylinder 3. The material finally enters the outer reaction cylinder 1 through the through pipe 6 on the surface of the inner reaction cylinder 3. Meanwhile, the material in the outer reaction cylinder 1 continues to enter the inner reaction cylinder 3 through the circular through hole at the bottom of the inner reaction cylinder 3. The stirring rod 10 in the outer reaction cylinder 1 rotates with the drive rod 8 to stir and mix the material in the outer reaction cylinder 1, so that the demulsifier and the emulsion are fully mixed and reacted. The one-way valve of the through pipe 6 ensures that the material flows in one direction. The conveying plate 9 and the stirring rod 10 fully mix the material inside and outside the inner reaction cylinder 3, respectively, increasing the reaction efficiency of the demulsifier and the emulsion.

[0035] A filtration and separation structure is provided below the outer reaction cylinder 1. The filtration and separation structure increases the efficiency of subsequent water washing by further filtering the reaction liquid. The filtration and separation structure includes a box body 11, which is located below the outer reaction cylinder 1. The box body 11 and the outer reaction cylinder 1 are connected by a discharge pipe 12. A valve is provided inside the discharge pipe 12. A square through hole is provided on the front surface of the box body 11. A filter box 13 slides through the square through hole on the surface of the box body 11. The surface of the filter box 13 is connected to the surface of the box body 11 by bolts. A filter screen is provided at the bottom of the filter box 13 and aligned with the lower end of the discharge pipe 12. A liquid outlet pipe 14 is provided through the front surface of the box body 11.

[0036] like Figure 1 and Figure 5As shown, after the demulsification reaction is completed, the valve of the discharge pipe 12 is opened, and the reaction liquid falls into the filter box 13 inside the box 11 through the discharge pipe 12. The liquid is filtered through the filter screen at the bottom of the filter box 13, and the resin particles in the reaction liquid are intercepted by the filter box 13. The filtrate is discharged from the discharge pipe 14. By filtering the reaction liquid, the efficiency of subsequent water washing is improved. After filtration is completed, the bolts on the surface of the filter box 13 are removed, and the filter box 13 is slid out from the surface of the box 11 for cleaning and replacement to ensure filtration efficiency.

[0037] Working principle: When using this resin production demulsifier to improve washing efficiency, the material is fed into the outer reaction cylinder 1 through the feed pipe 2. Steam is introduced through the steam inlet pipe 4 and discharged through the steam outlet pipe 5, so that the steam heats the device in the sandwich between the inner reaction cylinder 3 and the outer reaction cylinder 1. The motor 7 is started, and the motor 7 drives the drive rod 8 to rotate. The rotating drive rod 8 simultaneously drives the conveyor plate 9 and the stirring rod 10 to rotate. The rotating conveyor plate 9 conveys the material in the inner reaction cylinder 3 upward and flows into the outer reaction cylinder 1 through the through pipe 6. The rotating stirring rod 10 stirs and mixes the material in the outer reaction cylinder 1, so that the demulsifier and the emulsion react fully to carry out the demulsification process. After the reaction, the material goes through the discharge pipe 12 to the filter box 13. After filtration by the filter screen, the liquid is discharged from the liquid outlet pipe 14, completing the demulsification and filtration, improving the subsequent washing efficiency and increasing the overall practicality.
