Description

Technical Field

[0001] This utility model belongs to the field of toothpaste production technology, specifically relating to a vacuum homogenizing emulsifier. Background Technology

[0002] In the industrial production of toothpaste, the vacuum homogenizer is a key piece of equipment. Its working principle is to use the high shear force homogenization effect combined with the vacuum environment to promote the efficient mixing, emulsification and dispersion of multiphase materials (such as abrasives, humectants, surfactants, etc.), thereby producing a toothpaste product with a fine texture, stable performance and meeting quality standards.

[0003] However, most existing vacuum homogenizing emulsifiers lack automated cleaning functions, making it easy for material residues to accumulate and form scale on the inner wall of the tank during production. When switching between batches of different formulations, this residual scale can lead to cross-contamination between the different formulations, resulting in deviations in the product composition ratios and even quality problems such as excessive microbial levels.

[0004] While some existing technologies attempt to add automated cleaning functions to vacuum homogenizing emulsifiers, this design brings new technical problems: on the one hand, the automated cleaning components cause unevenness on the internal surface of the emulsifier, thus creating dead zones for stirring and reducing the emulsification effect; on the other hand, existing automated cleaning designs have cleaning blind spots, making it difficult to achieve comprehensive and thorough cleaning, resulting in poor overall cleaning effect. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum homogenizing emulsifier that solves the technical problems of existing technologies, which, although equipped with automated cleaning functions, result in uneven internal surfaces, thus affecting the emulsification effect, and also have cleaning blind spots and poor cleaning results.

[0006] This utility model discloses a vacuum homogenizing emulsifier, comprising:

[0007] The tank body has multiple fan-shaped movable holes evenly distributed around its central axis on its top surface.

[0008] A circular plate is coaxially and rotatably disposed on the top surface of the tank body, and completely covers the movable hole;

[0009] A rotary drive mechanism is installed between the tank body and the annular plate, and is used to drive the annular plate to rotate around the central axis of the tank body;

[0010] A stirring mechanism is located at the top center of the tank and inside the annular plate, for mixing and stirring the materials inside the tank.

[0011] Top plate, arranged above the annular plate;

[0012] A lifting drive mechanism is installed between the annular plate and the top plate to drive the top plate to perform vertical lifting movements.

[0013] Multiple infusion tubes are vertically installed on the bottom surface of the top plate and are arranged one-to-one with the movable holes. The infusion tubes pass through the annular plate and the corresponding movable holes in sequence and extend into the inside of the tank, and form an axial sliding fit with the annular plate.

[0014] The diversion box is installed on the top plate and is connected to each of the infusion tubes through pipelines;

[0015] Multiple spray blocks, with a hollow internal structure, are fitted to the movable holes and installed one by one at the bottom of the infusion tube and connected to it. Multiple spray nozzles are also provided on both sides.

[0016] The spray block of this application is perfectly matched with the fan-shaped movable hole. Under normal conditions, it is embedded in the hole, making the internal surface of the emulsifier smooth and flat, thereby avoiding material residue or dead corners in the mixing and improving the uniformity of emulsification. During cleaning, the spray block detaches from the movable hole and extends into the tank. Then, the spray block rotates forward and backward along the movable hole and forms a fan-shaped spray through the spray nozzles on both sides. This can fully cover the inside of the tank, forming a maximum cleaning coverage area, eliminating cleaning blind spots, and achieving a highly efficient and comprehensive cleaning effect.

[0017] Based on the above technical solution, the solution of this application can be further improved as follows:

[0018] Preferably, the tank body has a feed inlet at the top side, a vacuum interface on the outside of the feed inlet, a discharge outlet at the center of the bottom of the tank body, and multiple support legs around the bottom of the tank body. This solution optimizes the feeding, vacuuming, discharging, and support structures, significantly improving the reliability, flexibility, and production efficiency of the equipment.

[0019] Preferably, the rotary drive mechanism includes:

[0020] A servo motor is installed on the side wall of the tank.

[0021] The drive gear is connected to the output shaft of the servo motor for transmission.

[0022] A ring gear is located on the outer circumference of the circular ring plate and meshes with the drive gear. This solution achieves stable rotation of the circular ring plate through precise control and efficient transmission, which can drive the spray block to complete the comprehensive cleaning of the inner wall of the tank. It has the advantages of high precision, high load and corrosion resistance, and significantly improves the level of automation and reliability.

[0023] Preferably, it includes:

[0024] An annular guide rail is coaxially mounted on the top surface of the tank and sleeved on the outside of the stirring mechanism, with its outer circumference rotatably connected to the annular plate. This design achieves stable rotation of the annular plate, has a compact structure, strong load capacity, and low maintenance cost, significantly improving the operational reliability of the emulsifier.

[0025] Preferably, it includes:

[0026] Multiple guide sleeves are provided on the annular plate and are slidably sleeved with the infusion tubes one by one. This solution can constrain the radial swing of the infusion tubes, prevent the spray block from shaking during cleaning, and improve stable operation.

[0027] Preferably, the stirring mechanism includes:

[0028] A rotating support rod is rotatably installed at the center of the inner top surface of the tank.

[0029] A rotary motor is installed on the top surface of the tank and is connected to the rotary support rod for transmission.

[0030] Multiple stirring frames are evenly installed on the outer periphery of the rotating support rod. By adopting this solution, the stability of the emulsification process and product quality are significantly improved through rigid support, precise driving and multi-layer efficient mixing.

[0031] Preferably, the lifting drive mechanism includes:

[0032] Multiple drive cylinders are installed between the annular plate and the top plate, and are evenly distributed circumferentially with the central axis of the tank as the reference. By adopting this solution, the height of the top plate can be flexibly adjusted through high-precision synchronous drive and control of multiple cylinders. It has the characteristics of compact structure, strong synchronization and high load capacity, ensuring the automation level and cleaning effect of the emulsifier.

[0033] Through the above technical solution, this utility model achieves the following beneficial effects:

[0034] 1. The spray block of this application is perfectly compatible with the fan-shaped movable hole. Under normal conditions, it is embedded in the hole, making the internal surface of the emulsifier smooth and flat, thereby avoiding material residue or dead corners in the mixing and improving the uniformity of emulsification. During cleaning, the spray block detaches from the movable hole and extends into the tank. Then, the spray block rotates forward and backward along the movable hole and forms a fan-shaped spray through the spray nozzles on both sides. This can fully cover the inside of the tank, forming a maximum cleaning coverage area, eliminating cleaning blind spots, and achieving a highly efficient and comprehensive cleaning effect.

[0035] 2. This application achieves stable rotation of the ring plate through precise control of the servo motor and efficient transmission of the drive gear and the ring gear, thereby driving the spray block to complete the comprehensive cleaning of the inner wall of the tank. It has the advantages of high precision, high load and corrosion resistance, and significantly improves the level of automation and reliability. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0051] Example:

[0052] like Figures 1-6 As shown in the embodiment of this application, a vacuum homogenizing emulsifier is disclosed for efficient mixing, emulsification, dispersion and defoaming of various raw materials to form a fine paste. It also has an automated cleaning function, which can efficiently and comprehensively clean the internal surface of the emulsifier without affecting the operation of the equipment to remove residual substances or dirt. Its specific structure includes: a tank 1, a circular plate 2, a rotary drive mechanism 3, a stirring mechanism 4, a top plate 5, a lifting drive mechanism 6, multiple infusion pipes 7, a diversion box 8 and multiple spray blocks 9.

[0053] Tank 1 adopts a cylindrical design and serves as the core container for emulsification and mixing reactions. Its bottom is hemispherical to facilitate material discharge, while the top surface has multiple annular movable holes 101 evenly distributed around the central axis. Figure 7As shown, the movable hole 101 is preferably 3-6, which ensures both thorough cleaning and structural stability. A sealing ring can be provided at the top edge to cooperate with the annular plate 2 and achieve dynamic sealing.

[0054] The annular plate 2 is coaxially and rotatably disposed on the top surface of the tank 1, and completely covers the movable hole 101. It serves as a support base for other components, seals the tank 1, ensures the stability of the vacuum environment, and forms a dynamic seal with the top surface of the tank 1.

[0055] The rotary drive mechanism 3 is installed between the tank body 1 and the annular plate 2, and is used to drive the annular plate 2 to rotate around the central axis of the tank body 1.

[0056] The stirring mechanism 4 is located at the top center of the tank 1 and inside the annular plate 2, and is used to mix and stir the materials in the tank 1.

[0057] The top plate 5 is arranged above the annular plate 2 and serves as a fixed base for the infusion tube 7, thereby improving the stability of the overall structure.

[0058] The lifting drive mechanism 6 is installed between the annular plate 2 and the top plate 5, and is used to drive the top plate 5 to perform vertical lifting and lowering movements.

[0059] Multiple infusion tubes 7 are vertically installed on the bottom surface of the top plate 5 and are set one-to-one with the movable holes 101. The infusion tubes 7 pass through the annular plate 2 and the corresponding movable holes 101 in sequence and extend into the tank body 1, forming an axial sliding fit with the annular plate 2.

[0060] The diversion box 8 is installed on the top plate 5 and is connected to each infusion tube 7 through pipelines. It has one inlet for connecting to an external liquid supply system and multiple outlets for connecting to the infusion tubes 7 through pipelines.

[0061] The interior of the multiple spray blocks 9 is hollow, and their shape and size are adapted to the movable holes 101. They are installed one by one at the bottom of the infusion tube 7 and connected to it. Multiple spray ports 901 are also provided on both sides. Sealing plates are installed on the outer periphery and fit with the movable holes 101.

[0062] The spray block 9 of this invention is perfectly matched with the fan-shaped movable hole 101. Under normal conditions, it is embedded in the hole, making the internal surface of the emulsifier smooth and flat, thereby avoiding material residue or dead corners in the mixing and improving the uniformity of emulsification. During cleaning, the spray block 9 detaches from the movable hole 101 and extends into the tank 1. Then, the spray block 9 rotates forward and backward along the movable hole 101 and forms a fan-shaped spray through the spray nozzles 901 on both sides. This can fully cover the inside of the tank 1, forming a maximum cleaning coverage area, eliminating cleaning blind spots, and achieving a highly efficient and comprehensive cleaning effect.

[0063] In some embodiments, such as Figure 1 and Figure 2 As shown, a feed inlet 10 is provided on the top side of the tank body 1 to support continuous or batch addition of raw materials, solvents and additives; a vacuum interface 11 is provided on the outside of the feed inlet 10 to connect to an external vacuum pumping device to create a vacuum environment inside the tank body 1; a discharge port 12 is provided at the center of the bottom of the tank body 1 to support continuous or batch discharge and to serve as the discharge port for the cleaning liquid; multiple support legs 13 are provided around the bottom of the tank body 1 to form a stable support and ensure stable operation of the equipment.

[0064] The above settings optimize the feeding, vacuuming, discharging, and support structures, significantly improving the equipment's reliability, flexibility, and production efficiency.

[0065] In some embodiments, such as Figure 1 As shown, the rotary drive mechanism 3 includes:

[0066] The servo motor 31 is installed on the side wall of the tank 1, preferably rigidly connected to the tank 1 through a motor bracket, and connected to the main control system of the equipment, supporting forward and reverse rotation, speed adjustment and emergency stop functions;

[0067] The drive gear 32 is connected to the output shaft of the servo motor 31 via a transmission connection.

[0068] The annular gear ring 33 is located on the outer periphery of the annular plate 2 and meshes with the drive gear 32.

[0069] The aforementioned rotary drive mechanism 3, through the precise control of the servo motor 31 and the efficient transmission of the drive gear 32 and the ring gear 33, achieves stable rotation of the ring plate 2, thereby driving the spray block 9 to complete the comprehensive cleaning of the inner wall of the tank 1. It has the advantages of high precision, high load and corrosion resistance, significantly improving the level of automation and reliability.

[0070] In some embodiments, such as Figure 1 As shown, it includes:

[0071] The annular guide rail 14 is coaxially mounted on the top surface of the tank 1 and sleeved on the outside of the stirring mechanism 4. Its outer circumference is rotatably connected to the annular plate 2 to provide rotational support for the annular plate 2.

[0072] Specifically, the annular plate 2 is embedded with a deep groove ball bearing or a crossed roller bearing, thereby forming rolling contact with the outer periphery of the annular guide rail 14, which reduces the coefficient of friction and improves the smoothness of rotation.

[0073] By setting the annular guide rail 14, the stable rotation of the annular plate 2 is achieved. Its structure is compact, its load capacity is strong, and its maintenance cost is low, which significantly improves the operational reliability of the emulsifier.

[0074] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, it includes:

[0075] Multiple guide sleeves 15 are provided on the annular plate 2 and are slidably sleeved with the infusion tube 7 in a corresponding manner, which plays a guiding and limiting role and restricts the radial swing of the infusion tube 7.

[0076] By setting the guide sleeve 15, the radial oscillation of the infusion tube 7 can be constrained, preventing the spray block 9 from shaking during cleaning and improving stable operation.

[0077] In some embodiments, such as Figure 1 and Figure 6 As shown, the stirring mechanism 4 includes:

[0078] Rotary support rod 41 is rotatably installed at the center of the inner top surface of tank body 1;

[0079] A rotary motor 42 is installed on the top surface of the tank 1 and is connected to the rotary support rod 41 for transmission.

[0080] Multiple stirring frames 43 are evenly installed on the outer periphery of the rotating support rod 41.

[0081] The above-described design of the stirring mechanism 4, through the rigid support of the rotating support rod 41, the precise drive of the rotating motor 42, and the multi-layer efficient mixing of the stirring frame 43, significantly improves the stability of the emulsification process and the product quality.

[0082] In some embodiments, such as Figure 2 and Figure 6 As shown, the lifting drive mechanism 6 includes:

[0083] Multiple drive cylinders 61 are installed between the annular plate 2 and the top plate 5, and are evenly distributed around the central axis of the tank body 1. They are preferably electric telescopic rods or hydraulic cylinders, without specific limitations.

[0084] The above-mentioned design of the lifting drive mechanism 6, through high-precision synchronous drive and control of multiple cylinders, realizes flexible adjustment of the height of the top plate 5. It has the characteristics of compact structure, strong synchronization and high load capacity, ensuring the automation level and cleaning effect of the emulsifier.

[0085] The working principle of the above technical solution is as follows:

[0086] In normal mode: the spray block 9 is embedded in the movable hole 101, making the inner surface of the tank 1 smooth and flat, which can avoid material residue or dead corners of stirring and improve the uniformity of emulsification.

[0087] Cleaning mode:

[0088] First, the lifting drive mechanism 6 causes the top plate 5 to drive the infusion pipe 7 and the spray block 9 to descend vertically, so the spray block 9 gradually separates from the movable hole 101 and enters the tank 1.

[0089] Then, the rotary drive mechanism 3 drives the annular plate 2 to rotate in both directions, so that the infusion pipe 7 moves back and forth between the two ends of the movable hole 101. Thus, the infusion pipe 7 will drive the spray block 9 to rotate inside the tank 1, and the rotation trajectories of multiple spray blocks 9 can overlap to form a complete circle, thereby ensuring the comprehensiveness of spray cleaning.

[0090] At the same time, the external liquid supply system inputs the cleaning liquid into the distribution box 8, the distribution box 8 distributes the cleaning liquid evenly to each liquid delivery pipe 7, and then inputs it into the spray block 9 through the liquid delivery pipe 7. Finally, the spray block 9 forms a fan-shaped spray through the spray nozzles 901 on both sides of the spray block 9, thereby covering the inner wall of the tank 1 and the surface of the stirring mechanism 4 with high pressure spray.

[0091] Therefore, as the spray block 9 gradually descends and rotates in both directions, the internal surface of the emulsifier will be efficiently and comprehensively sprayed and cleaned, maximizing the cleaning coverage area and avoiding cleaning blind spots.

[0092] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details.
