Description

Technical Field

[0001] This utility model relates to the field of polyurethane adhesive production technology, and in particular to an emulsification device. Background Technology

[0002] In the production of products such as polyurethane adhesives that require emulsification processes, it is usually necessary to use emulsification equipment to fully mix the raw materials and emulsifiers to form a stable emulsion product. Polyurethane adhesives and other products are inherently highly adhesive. After the emulsification reaction is complete, a large amount of raw materials will adhere to the inner wall and bottom of the reactor, making them difficult to clean. Most existing equipment is not equipped with a dedicated self-cleaning mechanism, requiring manual disassembly and cleaning. This is not only cumbersome and labor-intensive, but also consumes a lot of production time and reduces production efficiency. Furthermore, manual cleaning is difficult to completely remove residual sticky raw materials, and long-term accumulation will affect the purity and quality of subsequent products, and may even lead to product performance degradation due to cross-contamination of raw materials.

[0003] Therefore, an emulsification device is needed to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide an emulsification device that can effectively solve the problems mentioned above.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An emulsification device includes a double-layer reactor and a base installed at the bottom of the double-layer reactor for support. A spiral tube is provided between the inner and outer layers of the double-layer reactor. The inlet and outlet of the spiral tube extend to the outside of the double-layer reactor. A lid is provided on the upper part of the double-layer reactor. An electric telescopic cylinder is provided on the middle side of the upper part of the lid. The piston rod of the electric telescopic cylinder passes through the upper part of the lid and is provided with a self-cleaning component for cleaning the inner wall of the inner layer of the double-layer reactor.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Example 1, as Figures 1-3 As shown, an emulsification device includes a double-layer reactor 1 and a base 2 installed at the bottom of the double-layer reactor 1 for support. A spiral tube 3 is provided between the inner and outer layers of the double-layer reactor 1. The inlet and outlet of the spiral tube 3 both extend to the outside of the double-layer reactor 1. A reactor cover 5 is provided on the upper part of the double-layer reactor 1. An electric telescopic cylinder 4 is provided on the middle side of the upper part of the reactor cover 5. The piston rod of the electric telescopic cylinder 4 passes through the upper part of the reactor cover 5 and is provided with a self-cleaning component 6 for cleaning the inner wall of the inner layer of the double-layer reactor 1. Furthermore, a water outlet is provided on the lower middle side of the double-layer reactor 1.

[0018] During the production of polyurethane adhesive raw materials, emulsifiers need to be added and mixed to form a stable emulsion adhesive. The polyurethane adhesive itself is sticky. After mixing, some polyurethane adhesive will adhere to the inner wall of the inner layer of the double-layer reactor 1. If it is not cleaned for a long time, it will affect the quality of the polyurethane adhesive after subsequent mixing.

[0019] The specific workflow of this device is as follows: First, ensure that all the polyurethane adhesive inside the double-layer reactor 1 has been poured out. Then, the staff connects the self-cleaning component 6 to the external water pipe. The steam pipe or hot water pipe can then be connected to the spiral pipe 3 with bolts or clamps, allowing steam or hot water to enter the spiral pipe 3 from the lower opening and flow out from the upper opening. The spiral pipe 3 is installed between the inner and outer layers of the double-layer reactor 1, so that the steam or hot water will transfer heat to the inner wall of the double-layer reactor 1 after passing through, heating the inner wall of the double-layer reactor 1, reducing the stickiness of the polyurethane adhesive remaining inside the inner layer of the double-layer reactor 1, and also recovering heat. Then, the staff started the electric telescopic cylinder 4 to move and opened the external water pipe, so that the self-cleaning component 6 sprayed water to rinse the inner wall of the double-layer reactor 1. Then, the electric telescopic cylinder 4 drove the self-cleaning component 6 to move downward to rinse other parts of the inner wall of the double-layer reactor 1. By first heating the inner wall of the double-layer reactor 1, the viscosity of the polyurethane adhesive was reduced, making rinsing easier and cleaning the residual polyurethane adhesive from the inner wall of the double-layer reactor 1.

[0020] In the above, the self-cleaning component 6 will rotate itself when rinsing the inner wall of the double-layer reactor 1, thereby improving the rinsing effect.

[0021] As described above, when the self-cleaning component 6 comes into contact with the bottom wall of the double-layer reactor 1, it will be driven to rotate under the action of the electric telescopic cylinder 4 to scrub the bottom of the double-layer reactor 1, clean the area of ​​the inner wall of the double-layer reactor 1, and then the rinse water will flow out through the outlet at the bottom of the double-layer reactor 1.

[0022] In Example 2, further, in order to achieve the purpose of rinsing the inner wall of the double-layer reactor 1 by self-rotation when the self-cleaning component 6 cleans it, please refer to... Figure 4 The self-cleaning component 6 includes a connecting shell 61 installed on the piston rod of the electric telescopic cylinder 4. The bottom of the connecting shell 61 is provided with a connecting pipe 63. The water inlet of the connecting pipe 63 is provided with an external hose 62 that passes through the connecting shell 61 and the lid 5. The lower part of the connecting pipe 63 is provided with a water distribution shell 64. The outer surface of the water distribution shell 64 is provided with several water spray pipes 65. The lower part of the water distribution shell 64 is provided with a brushing mechanism 66. Furthermore, several of the water spray pipes 65 are distributed at an angle.

[0023] The workflow of self-cleaning component 6 is as follows: The external water pipe is connected to the external hose 62 through a connector. Then, the external water pipe is opened, and the water source is transported to the water distribution shell 64 through the external hose 62 and the connecting pipe 63. The water is sprayed out from several spray pipes 65 to rinse the inner wall of the inner layer of the double-layer reactor 1. Then, the staff started the electric telescopic cylinder 4 to move it, which caused the electric telescopic cylinder 4 to move the self-cleaning component 6 downward. The water spray pipe 65, with its oblique design, sprayed water onto the inner wall of the double-layer reactor 1, which generated a reaction force. Through the design of the connecting pipe 63, which is rotatably installed in the connecting shell 61, the water spray pipe 65 drove the water distribution shell 64 and the connecting pipe 63 to rotate, so that the inner wall of the double-layer reactor 1 was rotated and rinsed, improving the cleaning effect.

[0024] In the above process, when the scrubbing mechanism 66 comes into contact with the bottom wall of the double-layer reactor 1, it will rotate to scrub the bottom wall of the double-layer reactor 1 and thoroughly clean the inside of the double-layer reactor 1.

[0025] As described above, when the connecting shell 61 moves downward, it will pull the external hose 62 to extend and retract, so that the external hose 62 can stably deliver water to the water distribution shell 64. Its external water pipe is high-pressure water, and the spray pipe 65 is a high-pressure nozzle.

[0026] The power supply method of the electric telescopic cylinder 4 mentioned above is well known to those skilled in the art and will not be described in detail here. The electric telescopic cylinder 4 is controlled by the external control panel of the double-layer reactor 1, and the control method is also well known to those skilled in the art and will not be described in detail here.

[0027] Furthermore, in order to achieve the purpose of scrubbing the bottom wall of the double-layer reactor 1 when the scrubbing mechanism 66 comes into contact with it, refer to... Figure 5 and Figure 6 The scrubbing mechanism 66 includes a circular shell 661 installed at the lower part of the water distribution shell 64. A cylindrical rod 663 is movably connected to the lower part of the inner cavity of the circular shell 661. A compression spring 662 located in the inner cavity of the circular shell 661 is provided on the upper part of the cylindrical rod 663. A spiral groove 668 is opened on the outer surface of the cylindrical rod 663. A rotating shell 666 is provided on the upper part of the outer surface of the cylindrical rod 663. Brushes 664 are provided on both the left and right sides of the upper part of the outer surface of the rotating shell 666. A vertex 667 is provided on the right side of the upper part of the inner surface of the rotating shell 666. A stop plate 665 is provided at the lower part of the cylindrical rod 663. Furthermore, the vertex 667 slides within the inner cavity of the spiral groove 668, and the longest diameter of the abutment plate 665 is greater than the diameter of the outlet of the double-layer reactor 1. Furthermore, the upper part of the rotating shell 666 is L-shaped, allowing the rotating shell 666 to rotate under the circular shell 661.

[0028] The working process of the scrubbing mechanism 66 is as follows: When the abutment 665 contacts the bottom wall of the double-layer reactor 1, it will push the cylindrical rod 663 to slide inside the circular shell 661. The abutment 665 has friction after contacting the double-layer reactor 1, so that the abutment 665 will not rotate. When the cylindrical rod 663 moves up and down inside the circular shell 661, it compresses the spring 662 to generate pressure. At the same time, the apex 667 moves inside the spiral groove 668. When the cylindrical rod 663 moves, it drives the rotating shell 666 to rotate through the apex 667 and the spiral groove 668. Then, the rotating shell 666 drives the brushes 664 on both sides to rotate, so that the brushes 664 brush the bottom wall of the double-layer reactor 1 and clean the bottom wall of the double-layer reactor 1. This completes the all-round cleaning of the inner wall of the double-layer reactor 1.

[0029] In the above, the design of the compression spring 662 can ensure the stability of the cylindrical rod 663 when it slides, and provide a buffer for the vertex 667.

[0030] It should be noted that the specific installation method, circuit connection method and control method of the electric telescopic cylinder 4 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
