Description

Technical Field

[0001] This utility model relates to the field of product processing technology, specifically to a sodium sulfate addition device for the production of sodium hexadecyl sulfonate. Background Technology

[0002] Sodium hexadecyl sulfate, an important anionic surfactant, is widely used in daily chemicals (such as detergents and cosmetics), textiles (such as dyeing auxiliaries), and pharmaceuticals (such as drug excipients). In its production, sodium sulfate, a key raw material for regulating product purity and performance, must first undergo pretreatment (dissolution and dispersion) with a neutralized aqueous solution of hexadecyl sulfate before proceeding to subsequent reaction steps. This pretreatment stage places extremely high demands on the complete dissolution of sodium sulfate—if undissolved sodium sulfate particles are present, it will lead to uneven concentrations in the subsequent reaction system, prolong the reaction cycle, and even affect the purity and performance of the final product (such as the foaming properties of daily chemical products and the dispersibility of textile auxiliaries).

[0003] Currently, the industry commonly uses reaction kettles or ordinary heated mixing tanks for sodium sulfate pretreatment. These devices only have basic heating and stirring functions and have obvious drawbacks:

[0004] Lack of agglomeration handling capability: Sodium sulfate is prone to forming hard lumps due to moisture absorption during storage. The stirring mechanism of traditional equipment can only drive the overall flow of the material and cannot break up the lumps. As a result, the inside of the lumps cannot come into contact with the heating medium, resulting in the phenomenon of "melting on the outside but not on the inside". Obvious particles can still be observed when sampling and testing, and the stirring time needs to be repeatedly extended, which reduces production efficiency.

[0005] High cost of manual assistance: In order to improve the problem of caking, some production scenarios require manual crushing of sodium sulfate caking before feeding. This not only increases the labor intensity of operators, but also easily introduces external dust and impurities during the manual crushing process, further affecting the purity of the material. In addition, manual operation is inefficient and difficult to adapt to the rhythm of continuous production lines. Therefore, it is necessary to develop a sodium sulfate addition device for the production of sodium hexadecyl sulfonate. Utility Model Content

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Please see Figures 1-5 The diagram shows a schematic representation of an embodiment of a sodium sulfate addition device for the production of sodium hexadecyl sulfonate according to this invention. Please refer to [link / reference]. Figures 1-5 This paper provides a detailed description of a sodium sulfate addition device for the production of sodium hexadecyl sulfonate.

[0032] A sodium sulfate addition device for the production of sodium hexadecyl sulfonate includes a heating and mixing chamber 100. Two hollow mounting shells 101 are symmetrically fixed at the bottom of the inner cavity of the heating and mixing chamber 100. Each mounting shell 101 has a vertical rotating rod 102 rotatably mounted inside via bearings. A transverse cam 103 is fixedly mounted in the middle of the rods of the two rotating rods 102. Each mounting shell 101 has a vertical guide plate 104 fixedly mounted inside. A transverse cam 103 is slidably mounted through the sidewall of each guide plate 104 via a linear bearing. Two slide rods 105 are fixedly provided with circular protrusions 106 at one end near the cam 103. The two circular protrusions 106 are provided with arc-shaped fan-shaped protrusions 107 that slide against the outer surface of the cam 103 on one side. A transverse spring 108 is fixedly provided between the guide plate 104 and the circular protrusions 106. A pressing plate 109 is fixedly provided at the other end of each slide rod 105. The two pressing plates 109 repeatedly press the substance to be dissolved after sliding laterally back and forth through the slide rods 105.

[0033] Several horizontally arranged support frames 200 are fixedly installed between the front and rear side walls of the inner cavity of the heating mixing box 100. Each support frame 200 has a vertical rod 201 rotatably mounted on its top via a bearing. Stirring blades 202 are arranged on the outer side of the rod 201 above the mounting shell 101. Two of the vertical rods 201 are located directly above two rotating rods 102 and drive the two rotating rods 102 to rotate synchronously via a reduction mechanism. All the vertical rods 201 are driven to rotate by a drive mechanism.

[0034] Furthermore, the gap in the slide rod 105 extends through the coil of the spring 108, and the spring 108 pushes the circular convex plate 106 so that the outer surface of the fan-shaped protrusion 107 is always in contact with the outer surface of the cam 103. The gap in the slide rod 105 extends through the coil of the spring 108, which can limit the extension and retraction direction of the spring 108 and reduce the deformation and displacement of the spring 108. The spring 108 pushes the circular convex plate 106 so that the outer surface of the fan-shaped protrusion 107 is always in contact with the outer surface of the cam 103, which can ensure that the slide rod 105 is stably driven to move laterally when the cam 103 rotates, thereby improving the continuity of the reciprocating extrusion action of the extrusion plate 109, reducing the problem of extrusion interruption caused by loose parts, and helping to maintain the stability of material extrusion processing.

[0035] Furthermore, the inner cavity of the mounting shell 101 is rectangular frame-shaped, and rectangular openings for the extrusion plate 109 to enter and exit are provided at the facing ends of the two mounting shells 101. The extrusion plate 109 is rectangular in shape, and a rubber sealing layer is provided around its outer side wall. The outer side of the rubber sealing layer is fitted to the inner side of the mounting shell 101. Extrusion teeth 110 are evenly arranged on the facing side of the two extrusion plates 109. The extrusion teeth 110 on both sides have triangular cross-sections and interlock with each other. The rectangular frame structure of the inner cavity of the mounting shell 101 facilitates the internal... The rectangular opening at one end of the component provides a channel for the extrusion plate 109 to enter and exit, ensuring the normal operation of the reciprocating extrusion action of the extrusion plate 109. The rubber sealing layer on the outer wall of the extrusion plate 109 can reduce the amount of material entering the mounting shell 101, protecting components such as the rotating rod 102 and cam 103 inside the mounting shell 101, and reducing the possibility of component failure due to material jamming. The triangular interlocking extrusion teeth 110 on the face-to-face side of the extrusion plate 109 can increase the contact area with the material, improve the extrusion and crushing effect on the material, and help to more fully process the material to be dissolved.

[0036] Furthermore, the top surface of each mounting shell 101 is a slope 111. The slope 111 is smoothly inclined and gradually decreases from both sides of the inner cavity of the heating mixing box 100 toward the center of the inner cavity. The slope 111 can guide the material put into the heating mixing box 100 to converge toward the center of the inner cavity, reducing the situation of material stagnation at the top of the mounting shell 101. This facilitates the subsequent extrusion plate 109 to extrude the material, improves the utilization rate of the material, and reduces the problem of insufficient local processing caused by material accumulation.

[0037] Furthermore, a funnel-shaped feeding hopper 112, wider at the top and narrower at the bottom, is fixedly installed on the top of the heating mixing chamber 100. The inner cavity of the feeding hopper 112 is connected to the inner cavity of the heating mixing chamber 100. A sealing cover 113 is hinged to the top of the feeding hopper 112. The shape of the feeding hopper 112, wider at the top and narrower at the bottom, facilitates the operator in feeding materials and reduces the possibility of materials spilling outside the heating mixing chamber 100 during the feeding process. The inner cavity of the feeding hopper 112 is connected to the inner cavity of the heating mixing chamber 100, which can ensure that materials enter the chamber smoothly. The sealing cover 113 hinged to the top of the feeding hopper 112 can be closed when no materials are being fed, which can reduce the entry of external impurities into the inner cavity of the heating mixing chamber 100 and ensure the purity of the materials to a certain extent. If the heating mixing chamber 100 is in a heating state, it can also reduce the loss of heat inside the chamber.

[0038] Furthermore, symmetrical "L"-shaped mounting bases 114 are fixedly installed on both sides of the bottom of the heating mixing tank 100. Each mounting base 114 has evenly spaced mounting holes 115. Through the mounting holes 115, the heating mixing tank 100 can be fixed to a designated workbench or ground using bolts or other connecting parts, improving the overall installation stability of the equipment and reducing shaking during operation. A discharge pipe 116 is fixedly installed at the center of the bottom of the heating mixing tank 100, communicating with the inner cavity of the heating mixing tank 100. The discharge pipe 116 is located directly below the middle of the two extrusion plates 109. A discharge valve 117 is installed on the discharge pipe 116. The discharge pipe 116 can discharge the processed solution, and the discharge valve 117 can control the timing and speed of discharge, which is convenient for coordinating with the rhythm of subsequent production processes and improving operational flexibility.

[0039] Furthermore, the reduction mechanism includes a first transverse reduction gear 203 fixed to the lower ends of two vertical rods 201. The first reduction gear 203 is located in the inner cavity of the mounting housing 101, and the rods of the two vertical rods 201 rotatably pass through the top of the mounting housing 101 via sealed bearings. A transverse support 204 is fixedly provided on the inner wall of the mounting housing 101. A vertical rotating shaft 205 is rotatably provided through the upper and lower walls of the support 204 via bearings. A second transverse reduction gear 206 meshing with the first reduction gear 203 is fixedly provided in the middle of the shaft of the rotating shaft 205. A third transverse reduction gear 207 is fixedly provided in the lower end of the rotating shaft 205. A fourth transverse reduction gear 208 meshing with the third reduction gear 207 is fixedly provided in the top end of the rotating rod 102. The second reduction gear 206... The diameter of the fourth reduction gear 208 is larger than the diameter of the first reduction gear 203 and the third reduction gear 207. In the reduction mechanism, the first reduction gear 203 at the lower end of the vertical rod 201, the rotating shaft 205 supported by the bracket 204 and the second reduction gear 206 and the third reduction gear 207 on it, and the fourth reduction gear 208 at the top of the rotating rod 102 form a multi-stage meshing transmission. The diameter of the second reduction gear 206 is larger than the diameter of the first reduction gear 203 and the third reduction gear 207, and the diameter of the fourth reduction gear 208 is larger than the diameter of the third reduction gear 207. This design can reduce the rotation speed of the vertical rod 201 and transmit it to the rotating rod 102, so that the rotation speed of the rotating rod 102 driving the cam 103 is more suitable for the reciprocating extrusion requirements of the extrusion plate 109, and avoid the extrusion being too fast and insufficient due to excessive rotation speed.

[0040] Furthermore, a hollow storage shell 209 is fixedly installed on the top of the heating mixing chamber 100. The driving mechanism includes driven bevel gears 210 fixed to the top of each vertical rod 201. All the driven bevel gears 210 are located in the inner cavity of the storage shell 209 and are arranged horizontally. The rod body of each vertical rod 201 rotates through the top wall of the heating mixing chamber 100 via a sealed bearing. A horizontal driving rod 211 is rotatably installed on the inner cavity side wall of the storage shell 209 via a bearing. A transmission bevel gear 212 corresponding to and meshing with all the driven bevel gears 210 is fixedly installed on the rod body of the driving rod 211. A horizontal servo motor 213 is fixedly installed on the top of the heating mixing chamber 100. The output shaft of the servo motor 213 is connected to the driving rod 211 via a coupling. The end of the 1 is fixedly connected, and the housing 209 provides installation and protection space for the components of the drive mechanism, reducing the interference of external dust and impurities on the components. In the drive mechanism, the driven bevel gear 210 at the top of the vertical rod 201, the transverse drive rod 211 and its transmission bevel gear 212, and the servo motor 213 cooperate. The servo motor 213 can provide stable driving force, which drives all the driven bevel gears 210 to rotate synchronously through the drive rod 211 and the transmission bevel gear 212, thereby causing all the vertical rods 201 to drive the stirring blades 202 to rotate, which helps to ensure the uniformity of material mixing at different positions in the heating mixing box 100. The vertical rod 201 passes through the top wall of the heating mixing box 100 through a sealed bearing, which can reduce the corrosion of the drive mechanism components by the materials or water vapor in the box and extend the service life of the components.

[0041] It should be noted that the heating mixing chamber 100 is also equipped with heating devices, such as several vertical electric heating tubes symmetrically fixed on the inner cavity side wall of the heating mixing chamber 100. The top of the electric heating tubes passes through the top wall of the heating mixing chamber 100 through a sealed terminal and extends to the outside for connecting to an external power supply. A temperature sensor is also fixedly installed on the inner cavity side wall of the heating mixing chamber 100. Its signal output terminal also passes through the top wall of the heating mixing chamber 100 through a sealed cable and is electrically connected to an external temperature controller.

[0042] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
