Abstract

Technical Field
[0001] This utility model relates to the field of fabric softener production technology, specifically a cationic surfactant blending device. Background Technology
[0002] Fabric softener is a daily chemical auxiliary agent used to improve the feel of textiles and reduce friction between fibers. Its core functional component is mostly a cationic surfactant (such as quaternary ammonium salts). These surfactants contain positively charged hydrophilic groups in their molecular structure, which can combine with negatively charged groups on the fiber surface to form a protective film, thereby making the fabric soft and antistatic. The softening effect of a single cationic surfactant is limited; it needs to be mixed with nonionic auxiliaries (such as emulsifiers) and deionized water in specific proportions to optimize performance. Therefore, cationic surfactants need to be blended before being used in fabric softeners.
[0003] Currently, the industry mostly uses traditional mixing devices for blending, achieving material mixing through single-shaft mixing blades. However, this method has the following shortcomings: Material residues are easily left on the inner wall of the tank, especially cationic surfactants which have high viscosity and are difficult to clean once they adhere to the surface, resulting in waste of raw materials and affecting the purity of the next blend.

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example 1: Please see Figure 1 and Figure 2 In this embodiment of the invention, a cationic surfactant blending device includes: Base 1, on which a lifting mechanism 7 and a support assembly are fixedly installed, the lifting mechanism 7 including a lifting seat 6; The top-open mixing tank 2 is set above the base 1 by a support assembly. The bottom of the mixing tank 2 is provided with a discharge port 8, and a gate valve is installed at the discharge port 8. A lid 3 is adapted to the mixing tank 2. The lid 3 is fixedly connected to the lifting seat 6. A feed inlet 24 is provided on the lid 3. A stirring mechanism is mounted on the tank cover 3 in a through-type rotating manner, and a wall scraping component is provided in the stirring mechanism; And a drive mechanism fixedly installed on the top surface of the tank lid 3, used to drive the stirring mechanism.
[0018] In this utility model, the base 1 fixes the mixing tank 2 through the support component, and the lifting mechanism 7 drives the tank cover 3 to rise and fall, so as to realize the tank body closing and opening; after the raw materials are added through the feed port 24, the drive mechanism drives the stirring mechanism to operate, and at the same time the scraping component cleans the tank wall synchronously. After the mixing is completed, the material is discharged through the discharge port 8 (with gate valve).
[0019] The design of the lifting tank lid 3 makes it easy to open and close, and facilitates cleaning and maintenance. The linkage between the wall scraping component and the stirring mechanism can reduce the adhesion of materials on the inner wall of the mixing tank 2, thereby reducing raw material waste.
[0020] Example 2: Please see Figure 3 Based on Example 1, the stirring mechanism includes a hollow shaft 18 that rotates through the center of the top surface of the tank cover 3, a plurality of evenly distributed stirring blades 21 are fixedly installed on the periphery of the hollow shaft 18, and a wall scraping assembly is fixedly installed on the periphery of the hollow shaft 18. A axially defined and circumferentially rotatable optical axis 19 is installed in the hollow shaft 18. The top end of the optical axis 19 extends above the hollow shaft 18, and the bottom end of the optical axis 19 extends below the hollow shaft 18. A screw conveyor blade 20 located below the hollow shaft 18 is fixedly installed on the periphery of the optical axis 19.
[0021] In this embodiment, the stirring mechanism adopts a dual-shaft design of "hollow shaft 18 + optical shaft 19". Motor 1 28 drives the hollow shaft 18 to rotate, which drives the stirring blade 21 to stir laterally; Motor 2 29 drives the optical shaft 19 to rotate independently, and its bottom auger blade 20 forms an axial flow field, which pushes the bottom material to surge upward.
[0022] The independent operation of the two shafts creates a composite flow field, which solves the problem of a single flow field in single-shaft mixing and improves the uniformity of mixing. In addition, the screw conveyor blade 20 can rotate in the opposite direction to assist in pumping materials during discharge, speeding up the discharge speed and reducing residue at the bottom of the tank.
[0023] Example 3: Please see Figure 3 Based on Embodiment 2, the wall scraping assembly includes three connecting rods 22 fixedly connected to the center of the periphery of the hollow shaft 18, and the three connecting rods 22 are distributed in a circumferential array about the hollow shaft 18; An inclined scraper 23 is fixedly installed at the end of the connecting rod 22 away from the hollow shaft 18. The side of the scraper 23 away from the connecting rod 22 slides in contact with the inner wall of the can lid 3.
[0024] The scraper assembly is connected to the scraper 23 by three circumferentially arrayed connecting rods 22. When the hollow shaft 18 rotates, the scraper 23 slides in contact with the inner wall of the mixing tank 2. The inclined design generates a downward pressing force on the material when rotating counterclockwise.
[0025] The scraper 23 thoroughly cleans the tank wall, avoiding adhesion problems caused by the high viscosity of cationic surfactants and ensuring blending purity. Furthermore, the pressure conveying action of the inclined scraper 23 and the upward pumping action of the screw conveyor 20 form convection, enhancing material circulation and improving blending efficiency.
[0026] Example 4: Please see Figure 3 and Figure 4 Based on Embodiment 2, the drive mechanism includes a first motor 28, a first driven pulley 25, a second motor 29, and a second driven pulley 32; Driven pulley 1 25 is fixedly installed at the top position of the outer periphery of hollow shaft 18, and driven pulley 2 32 is fixedly installed at the top position of the outer periphery of optical shaft 19; Motor 28 is fixedly installed on the top surface of the can lid 3. The output shaft of motor 28 is fixedly installed with drive pulley 27. Belt 26 is installed between drive pulley 27 and driven pulley 25. Motor 29 is fixedly installed on the top surface of the can cover 3. The output shaft of motor 29 is fixedly installed with drive pulley 30. Belt 31 is installed between drive pulley 30 and driven pulley 32.
[0027] The drive mechanism independently controls the two shafts via dual motors: Motor 1 (28) drives the hollow shaft 18 via drive pulley 27, belt 26, and driven pulley 25; Motor 2 (29) drives the optical shaft 19 via drive pulley 30, belt 31, and driven pulley 32, enabling independent adjustment of the speed and direction of the two shafts. This independent dual-motor control allows for flexible adjustment of the speed ratio between the stirring blades 21 and the auger blades 20 (e.g., reverse rotation or differential rotation) to adapt to the blending requirements of different materials.
[0028] Example 5: Please see Figure 1Based on embodiment 1, the support assembly includes a support ring 4 fixedly installed on the periphery of the mixing tank 2, and a plurality of axially arrayed support legs 5 are fixedly connected between the support ring 4 and the base 1.
[0029] The array distribution of the support legs 5 reserves space at the bottom of the tank, which facilitates the installation and operation of the discharge port 8.
[0030] Example 6: Please see Figure 1 and Figure 2 Based on embodiment 1, the lifting mechanism 7 includes a vertical plate 9 fixedly installed on the top surface of the base 1. Two vertically spaced protrusions 10 are fixedly installed on the upper part of the side of the vertical plate 9 near the mixing tank 2. A lead screw 14 is rotatably installed between the two protrusions 10, and two guide rods 13 are fixedly installed between the two protrusions 10. The lifting seat 6 is threadedly connected to the lead screw 14, and the lifting seat 6 is slidably connected to the two guide rods 13. The end of the lifting seat 6 away from the discharge port 8 is fixedly connected to the tank cover 3 through the connecting block 12. The bottom surface of the lower boss 10 is fixedly mounted with motor 3 11. The bottom end of the lead screw 14 rotates through the boss 10 and is fixedly connected to the output shaft end of motor 3 11.
[0031] In the lifting mechanism 7 provided in this embodiment, the motor 11 drives the lead screw 14 to rotate, and the lifting seat 6 slides up and down along the guide rod 13. The connecting block 12 drives the can lid 3 to rise and fall, realizing the automatic sealing and opening of the can. The lead screw 14 and the guide rod 13 cooperate to ensure the stability and accuracy of the lifting of the can lid 3, and avoid material leakage due to poor sealing.
[0032] Example 7: Please see Figure 3 Based on Example 1, the mixing tank 2 is provided with a cavity 17. The outer periphery of the mixing tank 2 is provided with an outlet pipe 15 and an inlet pipe 16 that communicate with the cavity 17 at the top and bottom positions, respectively. The outlet pipe 15 and the inlet pipe 16 are connected to an external liquid circulation temperature control device.
[0033] The cavity 17 of the blending tank 2 is connected to an external liquid circulation temperature control device through the liquid inlet pipe 16 and the liquid outlet pipe 15. The circulating medium (such as heat transfer oil) flows in the cavity 17 to achieve temperature regulation of the material in the tank, which can accurately control the blending temperature to ensure product stability.
[0034] Liquid circulation temperature control devices are an existing technology that has been widely used in many industrial and scientific research fields. They typically consist of a refrigeration system, a heating system, a control system, and a circulation system.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
