Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically to a mixing device for the safe production of vitamin C products. Background Technology

[0002] Effervescent tablets are formulated with a main drug, diluent, binder, disintegrant, lubricant, and other excipients. They offer numerous advantages, including a novel dosage form, convenient administration, rapid onset of action, good taste, and high patient compliance, making them particularly suitable for children, the elderly, and patients who have difficulty swallowing solid dosage forms. They disintegrate rapidly, have high bioavailability, and improve clinical efficacy. The large amount of foam produced during disintegration increases direct contact between the drug and the affected area, enhancing its therapeutic effect. They are also easy to carry, transport, and store. Vitamin C is an antioxidant vitamin, and lutein esters also possess antioxidant properties and protect eyesight. Since the human body cannot synthesize lutein, it must be supplemented externally to achieve its eye-protecting effect.

[0003] To produce effervescent tablets combining lutein esters and vitamin C, the two ingredients need to be mixed. During the mixing process, the lutein esters and vitamin C will adhere to the inner wall of the mixing device, requiring manual cleaning to remove the residue and reduce waste.

[0004] A prior art patent with publication number CN218530699U discloses a mixing cylinder with a top cover. The top cover has a feed inlet, and a feed tube for easy material addition is located above the feed inlet. The mixing cylinder has a discharge outlet on the same side as the feed tube, and a sealing plate is rotatably mounted at the discharge outlet. A drive shaft runs through the top cover and is rotatably connected to the top cover. A cover is located at the bottom of the drive shaft, and symmetrical rotating shafts are arranged on the cover. Each rotating shaft has a stirring assembly. Symmetrical support arms are arranged on the cover, and a scraper is located at the free end of each support arm. A motor is located on the top surface of the top cover, and the motor output is connected to the upper end of the drive shaft. This invention, by using scrapers, can remove residual material from the inner wall of the mixing cylinder, reducing material waste and minimizing the labor intensity of manual cleaning of the mixing cylinder's inner wall.

[0005] Existing devices, including those mentioned above, have gradually revealed shortcomings in the technology with use, mainly in the following aspects:

[0006] First, during the mixing process of lutein ester and vitamin C, the powder is easily stirred up by the stirring structure and spreads into the surrounding environment, causing an impact on the surrounding environment and posing a safety hazard to operators in the work environment.

[0007] Secondly, during the feeding process, lutein esters and vitamin C tend to clump together inside the material, causing them to fall into the tank in a pile-like manner. This makes it impossible to evenly disperse the material and affects the mixing efficiency of the mixing structure.

[0008] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a mixing device for the safe production of vitamin C products. This device overcomes the problems of traditional technologies where, during the mixing process of lutein esters and vitamin C, the mixing structure easily causes powder to be stirred up and dispersed into the surrounding environment, leading to environmental impact and safety hazards for operators. Furthermore, during the feeding process, the materials tend to clump together, resulting in them falling into the tank in piles, hindering uniform dispersion and affecting the mixing efficiency of the mixing structure.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A mixing device for safe production of vitamin C products includes a mixing tank, an inlet pipe rotatably connected to the inner cavity of the mixing tank at the top, a feed cylinder rotatably inserted into the upper end of the inlet pipe, and a flap valve rotatably installed inside the feed cylinder.

[0012] The lower end of the inlet pipe is fixedly connected to a chassis, and a support ring is coaxially provided below the chassis. Several material distribution rods are fixedly connected between the outer wall of the chassis and the upper surface of the support ring, and a material drop channel is formed through the area between adjacent material distribution rods. The width of the material drop channel is gradually widened from the center outward.

[0013] As an optimized solution, the lower surface of the support ring is surrounded by a number of vertically arranged side stirring plates, and the outer wall of the side stirring plates is in frictional contact with the inner wall of the mixing tank.

[0014] As an optimized solution, a bottom stirring plate is horizontally fixed to the bottom of the side stirring plate, and the bottom surface of the bottom stirring plate is in frictional contact with the inner bottom surface of the mixing tank.

[0015] As an optimized solution, an air inlet pipe is vertically and rotatably installed inside the mixing tank. Several air distribution cylinders that communicate with the inner cavity are fixedly connected side by side from top to bottom on the peripheral wall of the air inlet pipe. Several air distribution holes that communicate with the inner cavity are evenly distributed on the cylinder wall of the air distribution cylinder.

[0016] As an optimized solution, the air intake pipe is surrounded and fixed with several central stirring plates in the area between two adjacent vertical air distribution cylinders.

[0017] As an optimized solution, a breather valve communicating with the inner cavity of the mixing tank is fixedly connected to the top of the mixing tank.

[0018] As an optimized solution, a material distribution cone is fixed to the upper surface of the chassis, and the inlet pipe is surrounded by several outlets that communicate with its inner cavity on the side wall near the chassis.

[0019] As an optimized solution, a top gear ring is fixedly connected to the outer wall of the inlet pipe above the mixing tank, and a top drive motor is fixedly connected to the outer top of the mixing tank. The output end of the top drive motor meshes with the top gear ring using a gear.

[0020] As an optimized solution, the lower end of the air inlet pipe extends to the bottom of the mixing tank and is rotatably fitted with an air inlet cylinder.

[0021] As an optimized solution, a bottom gear ring is fixedly connected to the outer wall of the air intake pipe below the mixing tank, and a bottom drive motor is fixedly connected to the bottom of the mixing tank. The output end of the bottom drive motor meshes with the bottom gear ring using a gear.

[0022] As an optimized solution, the bottom of the mixing pipe near its outer wall is fixed with a discharge valve that communicates with its inner cavity.

[0023] As an optimized solution, the upper end of the air intake pipe and the outer end of the air distribution cylinder are sealed.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] Lutein esters and vitamin C are introduced through the feed cylinder. The incoming materials are then evenly discharged through the outlet under the action of the distribution cone. A discharge channel is formed between adjacent distribution rods, with the width of the channel gradually expanding outwards from the center. This allows small particles to fall first, while clumps are guided outwards by the distribution rods and fall outside the discharge channel. The clumps fall to the outer area of ​​the mixing tank, where externally rotating stirring blades efficiently mix and pulverize the clumps, improving pulverization efficiency. Furthermore, the gradually expanding width of the discharge channel allows the top drive motor to rotate, ensuring even dispersion and improving the uniformity of material distribution.

[0026] By rotating the air distribution cylinder, gas can be evenly sprayed out along the air distribution holes and come into contact with the materials during the mixing process, thereby achieving sterilization of the materials.

[0027] By installing a flap valve in the feed cylinder, the flap valve can be closed during the material mixing process to prevent powder from overflowing and to prevent gas from entering and blowing back into the feed cylinder. The breather valve can balance the internal pressure and ensure the mixing efficiency of the material. Attached Figure Description

[0039] A material distribution cone 5 is fixed to the upper surface of the chassis 4, and several discharge ports 3 that connect to the inner cavity are arranged around the side wall of the inlet pipe 2 near the chassis 4.

[0040] A top gear ring 6 is fixedly connected to the outer wall of the inlet pipe 2 above the mixing tank 1. A top drive motor 7 is fixedly connected to the top of the mixing tank 1. The output end of the top drive motor 7 meshes with the top gear ring 6 using gears.
