Description

Technical Field

[0001] This invention relates to the field of emulsification equipment technology, specifically to an emulsification equipment for the production of chemical materials. Background Technology

[0002] Emulsification equipment is an industrial device used to mix two or more immiscible liquids or solids to form a homogeneous emulsion. Its working principle primarily relies on mechanical forces, such as centrifugal and shear forces generated by high-speed rotation, to induce intense shearing, impact, and cavitation effects within the equipment, thereby achieving emulsification.

[0003] Laundry detergent, a common daily chemical product, is composed of various chemical materials such as surfactants, thickeners, degreasers, enzymes, and fabric softeners. During the production of laundry detergent, emulsification equipment is required to stir and mix these various chemical materials.

[0004] After various chemical materials constituting laundry detergent are added to an emulsification device, due to differences in the proportion and viscosity of each chemical material, existing technologies typically incorporate stirring blades in the emulsification device to agitate the various chemical materials and cause them to flow back and forth within the device. For example, an emulsification device for chemical material production, with application number CN202410732631.6, pushes the high-concentration raw liquid near the bottom outer side inward during stirring. Simultaneously, it uses rotational power to cause the raw liquid to spiral upward and inward. Furthermore, an adjustment mechanism coordinates the moving stirring blades with the spiraling raw liquid, thereby improving the mixing effect of the raw liquid inside the internal power rod and enhancing the emulsification effect.

[0005] However, in actual production, it was found that when the reciprocating rack moves horizontally, the raw liquid in the emulsification equipment undergoes a spiral upward and inward reciprocating change. This causes the raw material to interfere with the subsequent rising raw material after it rises to the highest point, resulting in some raw material not being able to fall effectively to the lower point and thus not being able to quickly participate in the next circulation flow, resulting in low production efficiency of laundry detergent emulsification. In addition, when producing laundry detergent using nonionic surfactants (AES) in winter, the AES solidifies at low temperatures, requiring additional shearing and crushing before being put into production, making the production process cumbersome.

[0006] Therefore, an emulsification device for chemical material production is proposed. Summary of the Invention

[0007] The purpose of this invention is to provide an emulsification device for chemical material production. By controlling the unidirectional circulation of the added laundry detergent chemical raw materials and utilizing the difference in rotation speed between the inner and outer ring stirring components to shear and break up the solidified AES, this invention solves the problems of the upper layer of chemical materials not being able to fall quickly to participate in the next circulation flow, and the cumbersome production process of laundry detergent in winter, resulting in low emulsification production efficiency. This invention can fully guarantee the production quality of laundry detergent and significantly improve the production efficiency of laundry detergent by controlling the unidirectional circulation of chemical materials and simplifying the production process.

[0008] In laundry detergent, the composition is as follows: sodium dodecylbenzenesulfonate (LAS): 4%, sodium fatty alcohol polyoxyethylene ether sulfate (AES): 12%–14%, thickener: 2%, degreasing agent: 3%–5%, soap solution: 3%–5%, and industrial salt: 0.5%–2%. It is evident that AES has the highest proportion after water. Furthermore, normal laundry detergent emulsification equipment does not have dedicated heating devices for AES. Therefore, during winter laundry detergent production, when the temperature is below 7°C, AES solidifies and becomes difficult to disperse during stirring. It not only fails to effectively participate in the circulation of various chemical materials but also struggles to mix evenly with other chemical materials. This necessitates separate shearing or preheating of AES in winter, resulting in cumbersome production processes and low laundry detergent production efficiency.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] An emulsification device for chemical material production includes an emulsification tank, a sealing cover, a geared motor, and a feeding pipe. The sealing cover has a feeding hole at its center. The device also includes a base, an outer ring stirring assembly, a transmission gear set, a feeding ring, an inner ring stirring assembly, and a grinding assembly. The base is installed at the bottom of the emulsification tank. The outer ring stirring assembly is installed between the emulsification tank and the sealing cover, extending into the emulsification tank. The transmission gear set is installed on the surface of the sealing cover. The feeding ring is installed on the top of the sealing cover, with its inner circumference flush with the outer circumference of the feeding hole. The inner ring stirring assembly is installed between the sealing cover and the base, with its top extending into the feeding ring. A gap exists between the top of the inner ring stirring assembly and the feeding ring to allow a small amount of chemical material to be fed into the emulsification tank through the feeding ring. When this small amount of chemical material comes into contact with the inner ring stirring assembly through the feeding ring, the inner ring stirring assembly disperses and evenly distributes the small amount of chemical material onto the AES surface within the emulsification tank. The transmission gear set is driven by the geared motor. The assembly is connected between the inner and outer ring stirring components. A geared motor drives both the inner and outer ring stirring components to rotate at corresponding speeds via a transmission gear assembly. The grinding assembly includes a first grinding seat and a second grinding seat. The first grinding seat is installed at the bottom of the outer ring stirring component, and the second grinding seat is installed at the bottom of the inner ring stirring component. The first and second grinding seats rotate at different speeds with the outer and inner ring stirring components. Due to the speed difference between the first and second grinding seats, AES will be sheared and crushed by the second grinding seat when it passes through the first grinding seat. This process pulverizes and refines the AES without heating, allowing for uniform mixing of AES with other chemical materials. The geared motor drives the inner and outer ring stirring components to rotate at different speeds via the transmission gear assembly. The inner and outer ring stirring components drive the fluid in the emulsification tank to circulate from top to bottom and from the outside to the inside. The first and second grinding seats rotate relative to each other at different speeds with the outer and inner ring stirring components, respectively.

[0011] As described above, the geared motor controls the outer and inner ring stirring components to rotate at different speeds via a transmission gear set. The inner and outer ring stirring components drive the chemical materials in the inner and outer rings to flow from bottom to top and from top to bottom, respectively. When the chemical materials flow to the high point in the emulsification tank and the bottom of the base, the flow direction is automatically changed, thereby enabling the chemical materials to circulate in one direction, thus ensuring the production quality and efficiency of the laundry detergent. In addition, the inner and outer ring stirring components rotating at different speeds drive the second and first grinding seats to rotate at different speeds, thereby shearing and crushing the AES that has solidified at low temperatures in winter. This simplifies the production process of laundry detergent in winter and significantly improves the production efficiency of laundry detergent in winter.

[0012] Preferably, the outer ring stirring assembly includes a rotating ring, an inner toothed groove, a limiting ring, a vertical rod, an outer scraper, and the limiting ring. The limiting ring is fixed between the emulsifying tank and the sealing cap. The rotating ring is rotatably disposed within the limiting ring. The inner toothed groove is constructed on the inner circumference of the rotating ring. The vertical rod is installed at the bottom of the rotating ring. The bottom ring is installed at the bottom of the vertical rod. The outer scrapers are installed at equal intervals on the vertical rod, with the front end of the outer scraper higher than the rear end in the clockwise direction.

[0013] As described above, when the outer ring stirring component rotates clockwise, it drives the chemical material that is attached to the inner wall of the emulsification tank to flow from top to bottom. When the chemical material flows to the bottom of the base, the flow direction of the chemical material is switched by the bottom surface of the base, so that the chemical material can smoothly participate in the circulation flow of the chemical material.

[0014] Preferably, the inner ring stirring assembly includes a rotating shaft, material distribution plates, a toothed ring, and an inner scraper. The toothed ring is rotatably mounted on the bottom of the sealing cover. The material distribution plates are arranged in a ring array about the center of the toothed ring and are installed on the inner circumference of the toothed ring. The rotating shaft is installed between the ends of the material distribution plates. The inner scraper is installed on the outer circumference of the rotating shaft, and the inner scraper and the outer scraper are staggered. In the clockwise direction, the front end of the inner scraper is lower than the rear end. The material distribution plates are inclined and in the clockwise direction, the front end of the material distribution plates is higher than the rear end.

[0015] As described above, when the inner ring stirring component rotates clockwise, it drives the chemical materials close to the central axis of the emulsification tank to flow from bottom to top, allowing the chemical materials to smoothly participate in the circulation of chemical materials.

[0016] Preferably, the transmission gear set includes a first transmission tooth, a drive tooth, and a second transmission tooth. The first transmission tooth, the drive tooth, and the second transmission tooth are all mounted on the sealing cover. The drive tooth meshes with the first transmission tooth and the second transmission tooth respectively. The first transmission tooth drives the rotating ring through an internal tooth groove. The drive tooth is sleeved on the output shaft of the reduction motor. A small gear is provided below the second transmission tooth, located below the sealing cover, and the small gear is coaxially arranged with the second transmission tooth. The small gear meshes with the gear ring.

[0017] As mentioned above, since the cross-sectional areas of the outer and inner ring stirring components driving the vertical flow of chemical materials differ, in order to avoid local accumulation in the emulsification tank due to large volume differences when chemical materials flow in different directions, by selecting an appropriate number of teeth, the circulation flow effect of the chemical materials can be avoided, and the problem of local accumulation of chemical materials in the emulsification tank that prevents them from circulating and participating in the flow can be effectively avoided. At the same time, the outer and inner ring stirring components rotate at different speeds, thereby creating a speed difference between the first grinding seat and the second grinding seat. The speed difference can be used to fully shear and break up the solidified AES, thereby significantly improving the production quality of laundry detergent.

[0018] Preferably, the first grinding seat includes a fixing rod, a feeding seat, a feeding groove, and a first grinding block. The fixing rod is installed at the bottom of the bottom ring, the feeding seat is installed at the bottom of the fixing rod, and the feeding seat is rotatably connected to the base. The feeding seat is located directly below the rotating shaft. The feeding groove is constructed on the outer periphery of the feeding seat. The first grinding block is installed on the top of the inner periphery of the feeding seat. The second grinding seat includes a fixing post and a second grinding block. The fixing post is installed at the bottom of the rotating shaft and extends to the inner side of the feeding seat. The second grinding block is fixed on the outer periphery of the fixing post. The top of the second grinding block is flush with the bottom of the first grinding block. The end of the first grinding block is in contact with the outer periphery of the fixing post, and the end of the second grinding block is in contact with the inner periphery of the feeding seat.

[0019] As described above, when the first grinding block and the second grinding block rotate relative to each other at different speeds, the AES that enters the feeding block through the feeding trough and is discharged from the top of the feeding block can be fully squeezed and sheared by the first grinding block and the second grinding block. In this way, by shearing and breaking the AES, the AES can be fully mixed with other chemical materials, thereby greatly improving the production quality of the laundry detergent.

[0020] Preferably, the fixing rod is fitted to the inner circumference of the base, and the number of fixing rods is at least four.

[0021] As mentioned above, when the fixed rod rotates with the bottom ring, it can continuously scrape the inner wall of the base, which can not only improve the stability of the outer ring stirring component during operation, but also effectively prevent raw material residue from remaining on the inner wall of the base after discharge.

[0022] Preferably, a horn seat is installed on the top of the delivery ring, and the top of the horn seat is higher than the top of the rotating shaft.

[0023] As mentioned above, the horn-shaped base is wider at the top and narrower at the bottom, which makes it convenient to add small amounts of chemical materials such as degreasing agents and thickeners into the emulsification tank.

[0024] Preferably, the inner circumference of the limiting ring has a notch, and the notch is adapted to the first transmission tooth.

[0025] As described above, the first transmission tooth meshes with the inner tooth groove of the inner circumference of the rotating ring inside the limiting ring through the notch, thereby realizing the meshing of the first transmission tooth with the rotating ring.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. In the production of laundry detergent emulsification, this invention can drive the chemical materials in the middle of the emulsification tank to flow upwards, while the chemical materials close to the inner wall of the emulsification tank flow downwards, forming a unidirectional circulation. This results in a stable mixing and emulsification effect, and also provides a large mixing cross-section, thereby significantly improving the mixing efficiency. In addition, by utilizing the speed difference between the inner and outer ring stirring components, when the chemical materials flow to the bottom of the base, the nonionic surfactant (AES) solidified at low temperature can be quickly sheared and broken. When producing laundry detergent emulsification in winter, there is no need to separately shear the AES, thus simplifying the emulsification process and significantly improving the emulsification production efficiency of laundry detergent.

[0028] 2. Through the set of transmission gears, since the flow cross-sections of the inner and outer ring chemical materials are different, the outer and inner ring stirring components can be driven to rotate at different speeds. Combined with a suitable number of teeth design, the volume of the upstream and downstream chemical materials can be kept close, thereby realizing the stable circulation of various chemical materials in the emulsification tank. Furthermore, the first and second grinding seats can rotate at different speeds, and the rotational differential speed can be used to shear and crush the solidified AES. This not only makes the production process of laundry detergent more stable, but also effectively ensures the production quality of laundry detergent under low temperature conditions in winter.

[0029] 3. Through the design of the sealing cap, rotating shaft, material distribution plate, and toothed ring, a gap exists between the rotating shaft and the sealing cap. When adding a small amount of degreasing agent, pigment, or other chemical materials into the emulsification tank, the material can be added using the feeding ring. As the raw material passes through the material distribution plate, the tilted plate disperses and distributes the chemical materials within the emulsification tank, ensuring even distribution on the surface of the added AES. This facilitates rapid and uniform mixing of the degreasing agent, pigment, and other chemical materials with the AES, effectively improving the production efficiency of laundry detergent and ensuring its quality.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1 to 8 This invention provides an emulsification device for chemical material production, the technical solution of which is as follows:

[0041] Reference Figure 1 , Figure 2 and 3An emulsification device for chemical material production includes an emulsification tank 1, a sealing cover 3, a geared motor 6, and a feeding pipe 9. The sealing cover 3 is located on the inner circumference of the top of the emulsification tank 1. The geared motor 6 is mounted on the top of the sealing cover 3 via a bracket. The feeding pipe 9 is mounted on the top of the sealing cover 3. A feeding hole is provided at the center of the sealing cover 3. The device also includes a base 2, an outer ring stirring assembly 4, a transmission gear set 5, a feeding ring 7, an inner ring stirring assembly 8, and a grinding assembly 10. The base 2 is installed at the bottom of the emulsification tank 1, and a discharge port is provided at the bottom of the base 2. The outer ring stirring assembly 4 is installed between the emulsification tank 1 and the sealing cover 3. The sealing cover 3 is fixedly connected to the emulsification tank 1 through the outer ring stirring assembly 4, and the outer ring stirring assembly 4 extends into the emulsification tank 1. The transmission gear set 5 is installed on the surface of the sealing cover 3. The feeding ring 7 is installed on top of the sealing cover 3. The inner ring stirring assembly 8 is installed between the sealing cover 3 and the base 2, and the top of the inner ring stirring assembly 8 extends into the feeding ring 7. The transmission gear set 5 is connected to the reduction motor 6, and the transmission gear set 5 is connected between the inner ring stirring assembly 8 and the outer ring stirring assembly 4. The grinding assembly 10 includes a first grinding seat 101 and a second grinding seat 102. The first grinding seat 101 is installed at the bottom of the outer ring stirring assembly 4, and the second grinding seat 102 is installed at the bottom of the inner ring stirring assembly 8. The reduction motor 6 drives the inner ring stirring assembly 8 and the outer ring stirring assembly 4 to rotate at different speeds through the transmission gear set 5. The inner ring stirring assembly 8 and the outer ring stirring assembly 4 drive the fluid in the emulsification tank 1 to circulate from top to bottom and from the outside to the inside. (Refer to...) Figure 8 The first grinding seat 101 and the second grinding seat 102 rotate relative to each other at different speeds with the outer ring stirring assembly 4 and the inner ring stirring assembly 8, respectively, to fully shear and break up the AES solidified in winter.

[0042] Reference Figure 4 In one embodiment of the present invention, specifically, the outer ring stirring assembly 4 includes a rotating ring 41, an inner toothed groove 411, a limiting ring 412, a vertical rod 42, an outer scraper 43, and a limiting ring 412. The limiting ring 412 is fixed between the emulsifying tank 1 and the sealing cap 3, with the outer periphery of the limiting ring 412 fixed to the emulsifying tank 1. The sealing cap 3 is fixed to the inner periphery of the limiting ring 412. The rotating ring 41 is rotatably disposed within the limiting ring 412, and the rotating ring 41 is connected to the limiting ring 412 by ball bearings for limiting rolling. The inner toothed groove 411 is constructed on the inner periphery of the rotating ring 41. The rotating ring 41 meshes with the first transmission tooth 51 through the internal tooth groove 411. The vertical rod 42 is installed at the bottom of the rotating ring 41. The number of vertical rods 42 is set to at least three, and the vertical rods 42 are evenly distributed. The bottom ring 44 is installed at the bottom of the vertical rod 42. The outer circumference of the bottom ring 44 is in contact with the inner circumference of the emulsion tank 1, which can improve the stability of the rotating ring 41 when it rotates. The outer scraper 43 is evenly installed on the vertical rod 42. The front end of the outer scraper 43 is higher than the rear end in the clockwise direction. When the outer scraper 43 rotates clockwise, it can drive the chemical material in contact with it to flow from top to bottom.

[0043] Reference Figure 3and Figure 5 In one embodiment of the present invention, specifically, the inner ring stirring assembly 8 includes a rotating shaft 81, material distribution plates 82, a toothed ring 83, and an inner scraper 84. The toothed ring 83 is rotatably mounted on the bottom of the sealing cover 3. The material distribution plates 82 are arranged in a ring array around the center of the toothed ring 83 and are mounted on the inner circumference of the toothed ring 83. The rotating shaft 81 is installed between the ends of the material distribution plates 82. The outer circumferential diameter of the rotating shaft 81 is smaller than the inner circumferential diameter of the feeding hole, so that a small proportion of chemical material can be added to the emulsification tank 1 through the gap between the rotating shaft 81 and the feeding hole. The inner scraper 84... 4 is installed on the outer periphery of the rotating shaft 81, and the inner scraper 84 and the outer scraper 43 are staggered to avoid collision between the inner scraper 84 and the outer scraper 43 when rotating. In the clockwise direction, the front end of the inner scraper 84 is lower than the rear end. When the inner scraper 84 rotates clockwise, it can drive the chemical material in contact with it to flow from bottom to top. The bulk material plate 82 is inclined, and in the clockwise direction, the front end of the bulk material plate 82 is higher than the rear end. When the bulk material plate 82 rotates clockwise, the chemical material with a small proportion will move into the emulsification tank 1 after contacting the bulk material plate 82.

[0044] Reference Figure 2 and Figure 5 As one embodiment of the present invention, specifically, the transmission gear set 5 includes a first transmission gear 51, a driving gear 52, and a second transmission gear 53. The first transmission gear 51, the driving gear 52, and the second transmission gear 53 are all mounted on the sealing cover 3. The driving gear 52 meshes with the first transmission gear 51 and the second transmission gear 53 respectively. The first transmission gear 51 is driven by the rotating ring 41 through the inner tooth groove 411. The driving gear 52 is sleeved on the output shaft of the reduction motor 6. The output shaft of the reduction motor 6 drives the driving gear 52 to rotate, thereby driving the first transmission gear 51 and the second transmission gear 53 to rotate at corresponding speeds. This enables the reduction motor 6 to provide power input to the outer ring stirring assembly 4 and the inner ring stirring assembly 8. A small gear 531 is provided below the second transmission gear 53 and located below the sealing cover 3. The small gear 531 is coaxially arranged with the second transmission gear 53. The small gear 531 meshes with the gear ring 83. The inner circumference of the limiting ring 412 has a notch, and the notch is adapted to the first transmission gear 51.

[0045] Reference Figure 4 , Figure 5 and Figure 6In one embodiment of the present invention, the first grinding seat 101 specifically includes a fixing rod 1011, a feeding seat 1012, a feeding groove 1013, and a first grinding block 1014. The fixing rod 1011 is installed at the bottom of the bottom ring 44, and the feeding seat 1012 is installed at the bottom of the fixing rod 1011. The feeding seat 1012 rotates together with the bottom ring 44 via the fixing rod 1011, and the feeding seat 1012 is rotatably connected to the base 2. The connection between the feeding seat 1012 and the base 2 provides support for the rotation of the rotating ring 41. The feeding seat 1012 is located directly below the rotating shaft 81. The feeding groove 1013 is constructed on the outer periphery of the feeding seat 1012. When the feeding seat 1012 rotates clockwise, the AES initially added in the emulsion tank 1 will enter the feeding seat 1012 through the feeding groove 1013. The AES then flows out from the top of the feed seat 1012. The first grinding block 1014 is installed on the top of the inner circumference of the feed seat 1012. The second grinding seat 102 includes a fixing post 1021 and a second grinding block 1022. The fixing post 1021 is installed at the bottom of the rotating shaft 81 and extends to the inner side of the feed seat 1012. The second grinding block 1022 is fixed on the outer circumference of the fixing post 1021. The top of the second grinding block 1022 is flush with the bottom of the first grinding block 1014. The end of the first grinding block 1014 is in contact with the outer circumference of the fixing post 1021. The end of the second grinding block 1022 is in contact with the inner circumference of the feed seat 1012. When the AES flows out from the top of the feed seat 1012, when the first grinding block 1014 and the second grinding block 1022 overlap, the outflowing AES will be sheared and crushed.

[0046] Reference Figure 4 As one embodiment of the present invention, specifically, the fixing rod 1011 is set to fit the inner circumference of the base 2, and the number of fixing rods 1011 is at least four. When the fixing rod 1011 rotates with the bottom ring 44, it can continuously scrape the inner wall of the base 2, thereby avoiding the presence of chemical material residue on the inner wall of the base 2, which is conducive to the full discharge of the prepared laundry detergent during subsequent discharge.

[0047] Reference Figure 1 As one embodiment of the present invention, specifically, a horn seat 71 is installed on the top of the feeding ring 7, and the top of the horn seat 71 is higher than the top of the rotating shaft 81. The horn seat 71 facilitates the feeding of a small proportion of chemical materials into the emulsification tank 1, while the larger proportions of water and AES are fed into the emulsification tank 1 through the feeding pipe 9.

[0048] Working principle: A relatively large amount of water and AES are pre-added to the emulsification tank 1 through the feeding pipe 9. Then, the power to the reduction motor 6 is turned on. The output shaft of the reduction motor 6 simultaneously drives the outer ring stirring assembly 4 and the inner ring stirring assembly 8 to rotate at different speeds via the transmission gear set 5. The first grinding seat 101 rotates at the same speed as the outer ring stirring assembly 4, and the second grinding seat 102 rotates at the same speed as the inner ring stirring assembly 8. The outer ring stirring assembly 4 causes the chemical material close to the inner wall of the emulsification tank 1 to flow from top to bottom, while the inner ring stirring assembly 8 causes the chemical material close to the shaft of the emulsification tank 1 to flow from top to bottom. The chemical material at the line flows from bottom to top and passes through the first grinding seat 101 during the flow, thereby forming a unidirectional circulation flow of the chemical material in the emulsification tank 1, ensuring the emulsification and mixing efficiency of the laundry detergent. At the same time, the chemical material passing through the first grinding seat 101 is sheared and crushed by the rotational speed difference between the first grinding seat 101 and the second grinding seat 102. The subsequent smaller proportion of chemical material is put into the emulsification tank 1 through the horn seat 71 and the feeding ring 7. When the chemical material comes into contact with the rotating inner ring stirring component 8, it is dispersed and distributed on the surface of AES and quickly participates in the circulation flow.

[0049] Specifically, the output shaft of the geared motor 6 drives the drive gear 52 to rotate, which in turn drives the first transmission gear 51 and the second transmission gear 53 to rotate. The second transmission gear 53 drives the coaxial pinion 531 to rotate. The first transmission gear 51 drives the rotating ring 41 to rotate within the limiting ring 412 through meshing with the inner tooth groove 411, and simultaneously drives the vertical rod 42, the outer scraper 43, and the bottom ring 44 to rotate. The outer scraper 43 rotates clockwise around the rotating shaft 81, close to the inner wall of the emulsifying tank 1, thereby driving the emulsion to adhere to the inner wall. The chemical material inside the emulsifying tank 1 flows from top to bottom. The pinion 531 drives the gear 52 ring to rotate through meshing with the gear ring 83, which in turn drives the material distribution plate 82, the inner scraper 84 and the rotating shaft 81 to rotate. The inner scraper 84 rotates clockwise around the rotating shaft 81, thereby driving the chemical material close to the axis of the emulsifying tank 1 to flow from bottom to top. When the chemical material flows to the bottom of the base 2 and changes its flow direction, it passes through the first grinding seat 101 and flows out from the top of the first grinding seat 101.

[0050] The second grinding block 1022 rotates at the same speed as the rotating shaft 81 via the fixed column 1021. The feed seat 1012 rotates at the same speed as the bottom ring 44 via the fixed rod 1011. The first grinding block 1014 rotates at the same speed as the feed seat 1012. When the chemical material is fed into the feed seat 1012 through the feed trough 1013 and flows out from the top of the feed seat 1012, the first grinding block 1014 and the second grinding block 1022 with different rotation speeds come into contact and shear and crush the outflowing chemical material to prevent AES from remaining in a solidified state, thereby fully emulsifying and mixing AES with water.

[0051] When a small amount of degreasing agent or other chemical materials are subsequently added to the emulsification tank 1 through the horn seat 71, the clockwise rotating loose material sheet 82 will contact the chemical materials and cause them to move towards the inside of the emulsification tank 1. After being dispersed, the materials will be distributed on the surface of the emulsified AES emulsion and then quickly participate in the circulation flow. Finally, the emulsified laundry detergent will be discharged from below the base 2 through the discharge port.
