Description

Technical Field

[0001] This utility model relates to the field of sodium hyaluronate gel production technology, and more specifically, to a mixing device for sodium hyaluronate production. Background Technology

[0002] Sodium hyaluronate gel, also known as sodium hyaluronate, is a glycosaminoglycan. Sodium hyaluronate is a high-molecular-weight polysaccharide with excellent moisturizing and lubricating properties. It is widely used in pharmaceuticals, cosmetics, food, and many other fields. Its production process requires high precision in the mixing stage, as product quality is closely related to the uniformity of the raw material mixing.

[0003] Chinese Patent Announcement No. 202220488355.X discloses a mixing device for the production and processing of sodium hyaluronate gel. The device includes a silo body with evenly distributed support legs at its base. A feed inlet is located on the top wall of the silo body, and the feed inlet is equipped with a vibrating anti-sticking mechanism. A rotary motor is mounted on the top wall of the silo body, with its output end penetrating through the top wall. A rotating shaft is located below the output end of the rotary motor, and stirring blades are mounted on both sides of the rotating shaft. This invention belongs to the field of sodium hyaluronate gel production technology, specifically referring to a mixing device for the production and processing of sodium hyaluronate gel that can vibrate and scrape material at the feed inlet, effectively preventing material from adhering to the inner wall of the feed inlet, thus avoiding waste and difficulty in cleaning.

[0004] However, the above-mentioned patent, after improvement, uses a motor to drive the stirring paddle to rotate in the container to mix the materials. In the production process of sodium hyaluronate, the viscosity of the raw materials may be relatively high. When mixed with some high-concentration thickeners, the simple stirring mixing device is prone to stirring dead zones, that is, the materials near the container wall or the bottom of the stirring paddle are difficult to be fully stirred, resulting in uneven mixing. Therefore, in order to solve the above problems, a mixing device for the production of sodium hyaluronate is proposed. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a mixing device for the production of sodium hyaluronate. A servo motor drives the spiral blades on the outside of the stirring rod to initially stir the material inside the inner cylinder, allowing for the preliminary mixing of materials with good flowability. The spiral blades enable simultaneous axial and radial mixing, making it suitable for processing sodium hyaluronate raw materials with high viscosity. The material is then transported to the bottom of the inner cylinder via a flexible hose and a fixed pipe. The flow of gas or liquid propels the material near the container wall and bottom, avoiding dead zones in the mixing process. The upward-angled fixed pipe allows gas to flow upwards along the inner wall of the cylinder after entering the container, effectively pushing the material near the wall.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0015] (2) This solution uses two vibrating motors connected to the inner walls of the outer cylinder on both sides by fixing bolts.

[0022] The servo motor 18 drives the spiral blades 6 on the outside of the stirring rod 4 to initially stir the material inside the inner cylinder 2, allowing the material with good flowability to be initially mixed. The spiral blades 6 can mix the material in both the axial and radial directions simultaneously, which is suitable for processing sodium hyaluronate raw materials with high viscosity. The material is then transported to the bottom of the inner cylinder 2 through the hose 12 and the fixed pipe 13. The flow of gas or liquid pushes the material near the container wall and bottom, avoiding dead zones in the stirring. The fixed pipe 13 is tilted upwards, allowing the gas to flow upwards along the inner wall of the inner cylinder 2 after entering the container, effectively pushing the material near the wall.

[0023] Meanwhile, the inner cylinder 2 is equipped with an inclined wall, which can guide the material to flow better during the mixing process and prevent the material from accumulating in the corners.

[0024] One-way valves 14 are provided inside the inner cylinder 2 and outside the several fixed pipes 13. Mounting plates 8 are fixedly installed inside the corresponding two sides of the outer cylinder 1. Vibration motors 7 are provided on the side of the two mounting plates 8 that are close to each other. The output ends of the two vibration motors 7 are fixedly connected to the inner cylinder 2.

[0025] Vibrating motors 7, which are connected to the inner walls of the outer cylinder 1 on both sides by fixing bolts, vibrate the inner cylinder 2 to break up any agglomerates that may form, so that the granular raw materials are evenly dispersed. At the same time, the gas outside the outer cylinder 1 is transported into the cavity 10 through the air inlet pipe 11 by the suction pump.

[0026] A servo motor 18 is fixedly installed inside the fixed base 3. A first gear 15, a second gear 16, and a third gear 17 are rotatably connected inside the fixed base 3. The second gear 16 meshes with the first gear 15 and the third gear 17. The output end of the servo motor 18 is fixedly connected to the first gear 15. A feed pipe 9 is provided at the bottom of the outer cylinder 1. The feed pipe 9 passes through the bottom of the outer cylinder 1 and is movably connected to it. The feed pipe 9 is inserted into the interior of the inner cylinder 2 and communicates with it. The feed pipe 9 is fixedly connected to the inner cylinder 2.

[0027] A stirring frame 19 is fixedly installed at the bottom of the third gear 17. The stirring frame 19 passes through the bottom of the fixed base 3 and is rotatably connected to it. The stirring frame 19 is slidably connected to the discharge port 5. A top plate is slidably connected to the top of the discharge port 5. Magnets are embedded on the sides of the discharge port 5 and the top that are close to each other.

[0028] The servo motor 18 drives the synchronous rotation of the stirring rod 4 and the stirring frame 19, causing the spiral blades 6 to rotate and stir the material inside the inner cylinder 2, as well as scrape the material on the inner wall of the discharge port 5, effectively preventing the material from adhering to the inner wall of the discharge port 5. At the same time, the servo motor 18 drives multiple structures to achieve centralized power supply, improving the energy utilization efficiency of a single motor.

[0029] Please see Figure 3 Two support rods 21 are fixedly installed at the bottom of the inner wall of the outer cylinder 1. Both support rods 21 are inserted into the inner cylinder 2 and slidably connected to it. Several shock-absorbing springs are fixedly installed on the outer side of the two support rods 21, and the ends of the shock-absorbing springs away from the support rods 21 are fixedly connected to the inner cylinder 2.

[0030] Several support legs are fixedly installed at the bottom of the outer cylinder 1. An air inlet pipe 11 is fixedly installed on one side of the outer cylinder 1. The air inlet pipe 11 is inserted into the cavity 10 and communicates with it. An air suction pump is provided on one side of the outer cylinder 1 and outside the air inlet pipe 11. A controller 20 is embedded on one side of the fixed base 3. The controller 20 is electrically connected to the vibration motor 7, the servo motor 18 and the air suction pump.

[0031] The device is controlled by the controller 20, and the inner cylinder 2 is supported by the support rod 21. The vibration of the inner cylinder 2 is reduced by the damping spring and the damping pads are fixedly installed on the side of the two mounting plates 8 near the outer cylinder 1. At the same time, the magnet and the top plate are used to cover the top of the discharge port 5.

[0032] Working principle: The servo motor 18 drives the spiral blades 6 on the outside of the stirring rod 4 to initially stir the material inside the inner cylinder 2, allowing the material with good flowability to be initially mixed. The spiral blades 6 can mix the material in both the axial and radial directions simultaneously, which is suitable for processing sodium hyaluronate raw materials with high viscosity. At the same time, the vibration motors 7 connected to the inner walls on both sides of the outer cylinder 1 by fixing bolts drive the inner cylinder 2 to vibrate, breaking up any agglomerates that may form and dispersing the granular raw materials evenly. Meanwhile, the suction pump delivers gas from outside the outer cylinder 1 into the cavity 10 through the air inlet pipe 11, and then through the hose 12 and fixed pipe 13 to the bottom of the inner cylinder 2. The flow of gas or liquid pushes the material near the container wall and bottom, avoiding dead zones in the stirring. The fixed pipe 13 is tilted upwards, allowing the gas to flow upwards along the inner wall of the inner cylinder 2 after entering the container, effectively pushing the material near the wall.
