A mixing and stirring device for waterless printing of polyester fabric

Abstract

This utility model relates to the field of polyester fabric technology and discloses a mixing and stirring device for waterless dyeing of polyester fabrics. The device includes a mixing tank and a coupling. A sealing cap is provided at the top of the mixing tank, and a motor is fixedly connected to the top of the sealing cap. The output shaft of the motor passes through the interior of the mixing tank and is fixedly connected to a connecting block via the coupling. In this utility model, when the shaft rotates, the upper layer of spiral blades with a narrower shaft diameter and denser pitch rapidly agitates the material, forming a strong vortex. As the shaft diameter decreases and the spiral blade pitch increases, the lower layer of spiral blades pushes the material downwards and diffuses it. Simultaneously, the material impacts the corrugated inner wall under centrifugal force. The uneven corrugated inner wall forces the material to change its direction of movement, interacting with the flow field generated by the spiral blades. This achieves three-dimensional cyclic mixing of the material in both horizontal and vertical directions, effectively improving the mixing uniformity.

Description

Technical Field

[0001] This utility model relates to the field of polyester fabric technology, specifically to a mixing and stirring device for waterless dyeing of polyester fabrics. Background Technology

[0002] Polyester fiber, commonly known as "polyester", is a synthetic fiber made by chemical polycondensation of organic dicarboxylic acids and diols. It belongs to a type of polymer compound. Polyester fabrics are usually produced using waterless dyeing technology, which can eliminate the use of water and harmful chemicals in the traditional dyeing process, and can also save water resources and reduce environmental pollution.

[0003] When polyester fabrics are dyed without water, they usually need to be stirred by a stirring structure to improve mixing efficiency. However, the equal diameter shaft and equal spacing blades of the traditional stirring structure are prone to stirring dead zones, resulting in uneven mixing of materials. Therefore, a mixing and stirring device for the waterless dyeing of polyester fabrics is needed. Utility Model Content

[0004] The purpose of this invention is to provide a mixing and stirring device for waterless dyeing of polyester fabrics, which solves the problems mentioned in the background art.

[0005] This application provides a mixing and stirring device for waterless dyeing of polyester fabrics, including a mixing tank and a coupling. The top of the mixing tank is covered with a sealing cover, and a motor is fixedly connected to the top of the sealing cover. The output shaft of the motor passes through the interior of the mixing tank and is fixedly connected to a connecting block through the coupling. A shaft is fixedly connected to the bottom of the connecting block. The diameter of the shaft decreases from top to bottom. Multiple helical blades are fixedly connected to the outer wall of the shaft along its extension direction. The spacing between the multiple helical blades gradually increases from top to bottom. The inner wall of the mixing tank is a corrugated inner wall.

[0006] In use, polyester fabrics are first fed into the mixing tank in batches through the feed inlet. Due to the batch feeding, a large amount of polyester fabric is placed at the top inside the mixing tank. Then, the motor is started by an external power switch. The motor's output shaft drives the shaft to rotate. When the shaft rotates, the upper spiral blades with a narrower shaft diameter and a denser pitch rapidly agitate the material, forming a strong vortex. As the shaft diameter decreases and the spiral blade pitch increases, the lower spiral blades push the material downwards and diffuse it. At the same time, the material impacts the corrugated inner wall under centrifugal force. The uneven corrugated inner wall forces the material to change its direction of movement, interacting with the flow field generated by the spiral blades to achieve three-dimensional circulation mixing of the material in both horizontal and vertical directions, which can effectively improve the mixing uniformity.

[0007] Optionally, the size of the plurality of helical blades gradually increases from top to bottom.

[0008] By adopting the above technical solution, the smaller upper spiral blades can finely stir and crush the material when the shaft diameter is large and the linear speed is high, while the larger lower spiral blades can better push and turn a large amount of material when the shaft diameter is small and the linear speed is slow, so that the material is fully mixed and stirred in the entire mixing tank.

[0009] Optionally, the bottom of the mixing tank is fixedly connected to four support legs and a discharge port, the discharge port being located in the middle of the four support legs, and a valve is installed on the discharge port.

[0010] By adopting the above technical solution, the mixing tank can be stably supported by the support legs, and the discharge port facilitates the discharge of materials.

[0011] Optionally, the top of the sealing cover is provided with a feed inlet, which is located on one side of the motor.

[0012] By adopting the above technical solution, it is beneficial to put the materials into the mixing tank for printing and dyeing.

[0013] Optionally, the outer wall of the connecting block is provided with an external thread that matches the coupling.

[0014] By adopting the above technical solution, it is beneficial to improve the firmness and stability of the connection between the connecting block and the coupling, thereby improving the firmness of the shaft installation.

[0015] Optionally, the connecting block and the shaft are an integral structure.

[0016] By adopting the above technical solution, it is beneficial to form the connecting block and the shaft in one piece, thereby improving the firmness of the connection between the connecting block and the shaft.

[0017] Optionally, the corrugated inner wall has alternating crests and troughs.

[0018] By adopting the above technical solution, the turbulence effect can be increased. The material will continuously change its flow direction and speed along the corrugated inner wall, so that the material in different areas can be fully mixed and exchanged. It also increases the collision and friction between the material and the inner wall of the mixing tank, thereby prolonging the residence time of the material in the mixing tank, which helps the materials to carry out more complete chemical reactions and improve the process effect.

[0019] Optionally, the edges of the helical blades are designed with rounded corners.

[0020] By adopting the above technical solution, it is possible to avoid damage to materials caused by excessively sharp edges of the spiral blades.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] In this application's technical solution, when the shaft rotates, the upper layer of spiral blades with a narrower shaft diameter and a denser pitch rapidly agitates the material, forming a strong vortex. As the shaft diameter decreases and the spiral blade pitch increases, the lower layer of spiral blades pushes the material downward and diffuses it. At the same time, the material impacts the corrugated inner wall under centrifugal force. The uneven corrugated inner wall forces the material to change its direction of motion and interacts with the flow field generated by the spiral blades, realizing three-dimensional circulation mixing of the material in both horizontal and vertical directions, which can effectively improve the mixing uniformity.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a mixing and stirring device for waterless dyeing of polyester fabrics, including a mixing tank 4 and a coupling 6. The top of the mixing tank 4 is covered with a sealing cover 1. A motor 2 is fixedly connected to the top of the sealing cover 1. The output shaft of the motor 2 passes through the interior of the mixing tank 4 and is fixedly connected to a connecting block 7 through the coupling 6. A shaft 9 is fixedly connected to the bottom of the connecting block 7. The diameter of the shaft 9 decreases from top to bottom. Multiple spiral blades 8 are fixedly connected to the outer wall of the shaft 9 along the extension direction. The spacing between the multiple spiral blades 8 gradually increases from top to bottom. The inner wall of the mixing tank 4 is a corrugated inner wall 10.

[0030] In the technical solution of this utility model, such as Figure 1As shown, the size of the multiple spiral blades 8 gradually increases from top to bottom; the smaller upper spiral blades 8 can finely stir and crush the material when the shaft diameter is larger and the linear speed is faster, while the larger lower spiral blades 8 can better push and turn a large amount of material when the shaft diameter is smaller and the linear speed is slower, so that the material is fully mixed and stirred in the entire mixing tank 4.

[0031] In the technical solution of this utility model, such as Figure 1 and Figure 2 As shown, the bottom of the mixing tank 4 is fixedly connected to four support legs 5 and a discharge port 11. The discharge port 11 is located in the middle of the four support legs 5 and a valve is installed on the discharge port 11. The support legs 5 can provide stable support for the mixing tank 4, and the discharge port 11 facilitates the discharge of materials.

[0032] In the technical solution of this utility model, such as Figure 2 As shown, the top of the sealing cover 1 is provided with a feed inlet 3, which is located on one side of the motor 2; this facilitates the feeding of materials into the mixing tank 4 for dyeing.

[0033] In the technical solution of this utility model, such as Figure 4 As shown, the outer wall of the connecting block 7 is provided with an external thread 12 that matches the coupling 6; this helps to improve the firmness and stability of the connection between the connecting block 7 and the coupling 6, thereby improving the firmness of the shaft 9 installation.

[0034] In the technical solution of this utility model, such as Figure 4 As shown, the connecting block 7 and the shaft 9 are an integral structure; this facilitates the integral molding of the connecting block 7 and the shaft 9 and improves the firmness of the connection between the connecting block 7 and the shaft 9.

[0035] In the technical solution of this utility model, such as Figure 3 As shown, the corrugated inner wall 10 has alternating crests and troughs, which can increase the turbulence effect. The material will continuously change its flow direction and speed along the corrugated inner wall 10, so that the material in different areas can be fully mixed and exchanged. It also increases the collision and friction between the material and the inner wall of the mixing tank 4, thereby prolonging the residence time of the material in the mixing tank 4, which helps the materials to carry out more complete chemical reactions and improve the process effect.

[0036] In the technical solution of this utility model, such as Figure 1 As shown, the edges of the spiral blades 8 are rounded, which can prevent the edges of the spiral blades 8 from being too sharp and causing damage to the materials.

[0037] In use, polyester fabrics are first fed into the mixing tank 4 in batches through the feed inlet 3. Due to the batch feeding of polyester fabrics, a large amount of polyester fabrics are placed at the top inside the mixing tank 4. Then, the motor 2 is started by the external power switch. The output shaft of the motor 2 can drive the shaft 9 to rotate. When the shaft 9 rotates, the upper spiral blades 8 with a narrower shaft diameter and a denser pitch quickly stir the material, forming a strong vortex. As the diameter of the shaft 9 decreases and the pitch of the spiral blades 8 increases, the lower spiral blades 8 push the material downward and diffuse. At the same time, the material impacts the corrugated inner wall 10 under the action of centrifugal force. The uneven corrugated inner wall 10 forces the material to change its direction of movement and interacts with the flow field generated by the spiral blades 8, realizing three-dimensional circulation mixing of the material in the horizontal and vertical directions, which can effectively improve the mixing uniformity.
