[0018] To facilitate understanding of this invention, a more complete description will be given below with reference to the embodiments, particularly the accompanying drawings. Preferred embodiments of the invention are shown in the embodiments. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.
[0019] Traditional material emulsification systems are not effective at emulsifying materials with high viscosity or high solids content. Due to the high viscosity or high solids content of the material, the bottom outlet of the mixing device, such as the agitator, becomes clogged during the feeding stage due to material sedimentation or excessive viscosity, preventing the emulsification operation from starting smoothly after feeding. To address this, this invention provides a novel material emulsification system comprising an external circulation loop and an emulsification loop, effectively solving the problem of clogging at the bottom outlet of the mixing device during the feeding stage.
[0020] This utility model provides a material emulsification system, see [link to relevant documentation] Figure 1 It includes a mixing device 1, an emulsification circuit 2 and an external circulation circuit 3, wherein the first end of the emulsification circuit 2 is connected to the bottom outlet of the mixing device 1 and the second end of the emulsification circuit 2 is connected to the top opening of the mixing device 1; the first end of the external circulation circuit 3 is connected to the bottom outlet of the mixing device 1 and the second end of the external circulation circuit 3 is connected to the middle opening of the mixing device 1.
[0021] The mixing device 1 is equipped with a dispersing device and a stirring device. The dispersing device includes a dispersing motor 111 located on the top outer side of the mixing device and a dispersing rod 112 located inside the mixing device; the dispersing motor is connected to the dispersing rod, and dispersing blades 1121 are arranged circumferentially on the dispersing rod. The stirring device includes a stirring motor 121 and a reducer 122 located on the top outer side of the mixing device, and a stirring rod 123 located inside the mixing device; the stirring motor is connected to the stirring rod via the reducer, and stirring blades 1231 are arranged circumferentially on the stirring rod; a U-shaped stirring blade 1232 is provided at the end of the stirring rod away from the stirring motor to facilitate mixing materials located near the inner wall of the mixing device; a variable angle scraper 1233 is provided on the portion of the U-shaped stirring blade relative to the bottom area of the mixing device. A perforation is provided on one side of the variable angle scraper 1233. The variable angle scraper 1233 is connected to the bottom area of the U-shaped stirring blade through this perforation, thereby ensuring that the variable angle scraper 1233 can rotate relative to the U-shaped stirring blade. The other side of the variable angle scraper 1233 can be attached to the bottom of the mixing tank, allowing it to scrape the material on the bottom inner wall of the mixing tank, thus preventing material from settling at the bottom of the mixing device. The dispersing blades 1121 and the stirring blades 1231 are arranged at intervals in the longitudinal direction of the mixing device. The simultaneous use of a dispersing device and a stirring device allows the material to form a vortex within the tank, thereby uniformly dispersing the solids into the liquid. The dispersing device motor 111 and the stirring device motor 121 can be AC variable frequency motors whose power is adapted to the material volume and viscosity. As an example, the dispersing device motor 111 has a power of 5.5kW and a speed of 0-2900r / min; speed is controlled by a frequency converter. As an example, the stirring device motor 121 has a power of 2.2kW and a speed of 0-80r / min; speed is controlled by a frequency converter. The reducer 122 can be a single-stage or multi-stage gear reducer with a power adapted to the power of the stirring motor. As an example, a SEW RF67 vertical reducer can be used.
[0022] The top of the mixing device is also provided with an opening 13 with a sealing strip for feeding materials. Optionally, a heat exchange device 14 can be provided outside the mixing device to heat or cool the materials inside. The heat exchange device is typically an indirect heat exchange device, and the heat exchange medium can be any medium commonly used in the art for heat exchange, such as water. The heat exchange device includes a medium inlet 141 located at the lower part of the outside of the mixing device and a medium outlet 142 located at the upper part of the outside of the mixing device. The mixing device can be any container known in the art for mixing materials, such as a tank, kettle, etc.
[0023] The bottom outlet of the mixing device is equipped with a discharge valve 15, which is connected to the first end of the emulsification circuit and the first end of the external circulation circuit via a three-way connector 16. The first end of the emulsification circuit and the first end of the external circulation circuit are respectively equipped with valves to connect or disconnect the corresponding circuits at any time.
[0024] The external circulation loop 3 includes a first pump 31. The first end of the first pump is the first end of the external circulation loop, connected to the bottom outlet of the mixing device; the second end of the first pump is the second end of the external circulation loop, connected to the central opening of the mixing device. A valve is provided at the central opening of the mixing device, typically a top-bottom valve that allows unidirectional material flow. Preferably, the first end of the first pump is the discharge end of the first pump, and the second end of the first pump is the feed end of the first pump.
[0025] The emulsification circuit 2 includes an emulsification pump 21. A first end of the emulsification pump 21 is the first end of the emulsification circuit 2 and is connected to the bottom outlet of the mixing device. A second end of the emulsification pump 21 is the second end of the emulsification circuit and is connected to the top opening of the mixing device. Alternatively, the emulsification circuit may further include a second pump 22, in which case the first end of the emulsification pump 21 is connected to the second end of the second pump 22, and the first end of the second pump 22 is connected to the bottom outlet of the mixing device. The second pump 22 provides a pressure head for the flow of material in the emulsification circuit to facilitate material flow. Preferably, the first end of the emulsification pump 21 is the feed end of the emulsification pump 21, the second end of the emulsification pump 21 is the discharge end of the emulsification pump 21, and the first end of the second pump 22 is the feed end of the second pump 22, and the second end of the second pump 22 is the discharge end of the second pump 22.
[0026] Both the first pump 31 and the second pump 22 can be rotary pumps, especially sanitary rotary pumps. The emulsifying pump 21 is typically a sanitary emulsifying pump. This allows it to be used for processing food-grade materials.
[0027] A valve is installed between the bottom outlet of the mixing device 1 and the tee connector 16. This valve is generally a top-bottom valve that only allows unidirectional material flow. Unless otherwise specified, the valves used in the emulsification circuit and the external circulation circuit are butterfly valves.
[0028] The material emulsification system also includes a control device 4, such as a control cabinet, which controls the system's mixing device, emulsification circuit, and external circulation circuit to operate the material feeding, emulsification, and discharging.
[0029] During the feeding stage, control device 4 controls the closure of emulsification circuit 2 and the opening of external circulation circuit 3. Specifically, the stirring device and dispersing device are turned on, the valve at the first end of the external circulation circuit is opened, the first pump 31 is started, the valve at the middle opening of mixing device 1 is opened, and the valve at the first end of emulsification circuit 2 is closed simultaneously. Material is fed into mixing device 1, and the first pump 31 simultaneously draws the material from the middle opening of mixing device 1 and pumps it into the bottom outlet of mixing device, forming a backflow. This ensures that the material at the bottom outlet of mixing device is in a flowing state and improves the mixing degree of the material at the bottom of mixing device. Simultaneously, the variable angle scraper 1233 of the U-shaped stirring blades 1232 of the stirring device, relative to the bottom area of the mixing device, can scrape the material on the bottom inner wall of the mixing tank, thereby preventing material from settling at the bottom of the mixing device. Multiple measures prevent material from settling at the bottom of the mixing device and from remaining at the bottom outlet, thus effectively preventing blockage of the discharge port.
[0030] After feeding is completed, the control device 4 controls the opening of the emulsification circuit 2 and the closing of the external circulation circuit 3 to perform emulsification. Specifically, the valve at the first end of the external circulation circuit, the first pump 31, and the valve at the middle opening of the mixing device are closed; the valve at the first end of the emulsification circuit 2, the emulsification pump 21, and the second pump 22 are opened, drawing the material from the bottom outlet. After emulsification by the emulsification pump 21, the material returns to the mixing device from the top to further emulsify it. This ensures that the material at the bottom outlet is in a flowing state during feeding and emulsification, preventing blockage at the bottom outlet and affecting the discharge.
[0031] According to the technical solution of the present invention, the material emulsification system, by setting an external circulation loop 3 and a variable angle scraper 1233 located on the U-shaped stirring blade 1232 relative to the bottom area of the mixing device, avoids material deposition at the bottom of the mixing device and lingering at the bottom outlet, thereby effectively avoiding blockage of the discharge port.

Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
