DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0022] In order to solve the problem that when the existing niacinamide powder comes into contact with the solvent during the preparation process and is stirred before being completely dissolved, caking will occur, resulting in waste of raw materials; please refer to Figures 1-3 , the present utility model provides the following solutions:

[0023] A mixing device for a niacinamide stock solution of cosmetics, comprising a mixing tank body 2 and a support frame 1. Above the mixing tank body 2, there is a cover 4, and above the cover 4, there is a motor assembly 3. Among them, on both sides of the cover 4, there are trusses 101, and the trusses 101 are connected to the cover 4 by bolts. The support frame 1 is located on both sides of the mixing tank body 2, and inside the support frame 1, there is a hydraulic assembly 102. The trusses 101 are telescopically connected to the support frame 1 through the hydraulic assembly 102. On the outer surface of the cover 4, there is a detection window 402, and around the cover 4, there are multiple locking bolts 401. Among them, the cover 4 is combined with the mixing tank body 2 through the locking bolts 401. Below the motor assembly 3, there is a transmission shaft 301, and the transmission shaft 301 extends into the inner tank 204. On both sides of the transmission shaft 301, there are stirring rods 302;

[0024] In this embodiment, after the premixed suspension enters the main tank, the variable-frequency motor assembly 3 drives the symmetrically arranged wide-impeller stirring rods 302 to generate a gentle axial flow at a low speed, avoiding high-shear damage to the formed swelling structure, while maintaining temperature uniformity and promoting the slow dissociation of niacinamide molecules. The angle of the stirring rods 302 matches the dome-shaped structure at the bottom of the tank, eliminating dead zones in the flow and preventing undissolved particles from depositing. After dissolution is completed, it is discharged through the discharge bottom valve 202 to avoid residual liquid retention.

[0025] The mixing tank body 2 includes an inner tank 204 and an outer tank 205, and the inner tank 204 and the outer tank 205 are set as an integrally formed structure. Among them, below the inner tank 204, there is a centrifugal premixing chamber 203, and the centrifugal premixing chamber 203 is connected to the inner tank 204 through a pipeline. On the outer surface of the mixing tank body 2, there are two mixing valves 201, and the mixing valves 201 extend into the centrifugal premixing chamber 203. At the bottom of the centrifugal premixing chamber 203, there is a sewage discharge pipe 2031, and at the bottom of the inner tank 204, there is a discharge bottom valve 202, and the discharge bottom valve 202 extends to the outside of the outer tank 205;

[0026] In this embodiment, the niacinamide powder is injected into the high-speed rotating centrifugal premixing chamber 203 through the top feeding port, and a uniform powder thin layer is formed along the chamber wall under the action of centrifugal force. The solvent impacts the powder layer with a high-pressure jet through the tangentially designed mixing valve 201, instantly breaking the powder agglomerates and realizing the contact mode conversion from powder wrapping droplets to droplets wrapping powder, fundamentally preventing surface caking and hardening. The conical diversion structure at the bottom of the chamber prolongs the contact time between the powder and the liquid, ensuring sufficient wetting of the particles. There is no mechanical stirring part inside the chamber, relying on the synergistic action of hydrodynamic shear and centrifugal acceleration, continuously colliding and breaking the undissolved fine particles. After forming a stable suspension, it is transported to the main tank through a pipeline.

[0027] Working principle: The niacinamide powder is injected into the high-speed rotating centrifugal premixing chamber 203 through the top feeding port, and a uniform powder thin layer is formed along the chamber wall under the action of centrifugal force. The solvent impacts the powder layer with a high-pressure jet through the tangentially designed mixing valve 201, instantly breaking the powder agglomerates and realizing the contact mode conversion from powder wrapping droplets to droplets wrapping powder. After the premixed suspension enters the main tank, the variable-frequency motor assembly 3 drives the symmetrically arranged wide impeller stirring rods 302, generating a gentle axial flow at a low speed, avoiding high-shear damage to the formed swelling structure, maintaining temperature uniformity at the same time, and promoting the slow dissociation of niacinamide molecules. The angle of the stirring rod 302 matches the dome-shaped structure at the bottom of the tank, eliminating the dead zone of flow and preventing the deposition of undissolved particles. After dissolution is completed, it is discharged through the bottom discharge valve 202 to avoid residual liquid retention.
