Description

High-shear emulsifying machine capable of preventing grinding gap from being blocked

Technical Field

Background

The high-shear dispersion emulsifying machine is an essential device in the manufacturing process of cosmetic cream products, and is especially suitable for producing high-grade skin care products or products. The working principle of the high-shear emulsifying machine is as follows: the materials move at high speed in the gap between the multilayer rotor and the stator to form strong hydraulic shearing and turbulence, disperse the materials, and simultaneously generate comprehensive acting forces such as centrifugal force extrusion, grinding, collision and the like, so that the materials are fully mixed, stirred and refined to meet ideal requirements. The shearing machine head adopts a claw type and bidirectional material sucking structure, so that the phenomena of dead angles and vortexes caused by the fact that upper materials are difficult to suck are avoided, and a rotor rotating at a high speed generates strong shearing force, so that the shearing rate is higher, and the shearing force is stronger.

Referring to fig. 1 and fig. 4, the lower liquid inlet 301 is much larger than the rotor clear liquid channel 302, so when the negative pressure generated by the rotation of the rotor 1 sucks the liquid into the rotor 1, the liquid flow enters the rotor cleaning box 3 from the lower liquid inlet 301, and when the liquid flow passes through the rotor clear liquid channel 302, the rotor clear liquid channel 302 is narrowed, the liquid flow rate is increased, and the liquid tangentially flows through the outer wall of the rotor 1, so that the adhered material on the rotor 1 can be washed away, and the outer wall of the rotor 1 can be cleaned. A stator pressing plate 303 is arranged above the rotor cleaning box 3, the stator pressing plate 303 is T-shaped, high in the middle and low in the edge, when the rotor cleaning box 3 moves upwards, the bottom end of the rotor 1 is pressed against the edge of the rotor cleaning liquid channel 302, the part of the main rotating shaft 8 extending to the bottom end of the impeller is just pressed against the middle part of the stator pressing plate 303, the blades of the impeller are not in contact with the surface of the stator pressing plate 303 but are positioned above the surface of the stator pressing plate 303, a certain gap is formed between the blades of the impeller and the top surface of the stator pressing plate 303, so that the impeller is prevented from rotating, and although one end of the main rotating shaft 8 extending to the lower part of the impeller is pressed against the surface of the stator pressing plate 303, the friction force between the two is small, so that the stator pressing plate 303 does not prevent the main rotating shaft 8 from rotating; in order to further reduce the contact friction force between the main rotating shaft 8 and the rotor 1 and the stator pressing plate 303, the middle and the periphery of the top surface of the stator pressing plate 303 are provided with rotary seats, the rotary seats can be bearings, so that the main rotating shaft 8 is in contact with the rotary seats in the middle, the rotor 1 is in contact with the rotary seats in the periphery, the purpose of independent operation of the stator pressing plate 303 and the main rotating shaft 8 is realized by using the smaller rotary friction force of the bearings, when the main rotating shaft 8 rotates, the stator pressing plate 303 keeps radial stability, and when the rotor cleaning box 3 continues to move upwards, the rotor 1 extrudes the stator pressing plate 303 to gradually move downwards, so that the spring 304 connected below the stator pressing plate 303 is compressed, and the outer wall of the rotor 1 is located at the rotor cleaning liquid channel 302, so that the liquid flow can flow along the outer wall of the rotor 1. In addition, a bellows 305 is connected to the outer periphery of the stator pressing plate 303, and the bellows 305 prevents the liquid entering the rotor clear liquid passage 302 from flowing into a cavity below the stator pressing plate 303, but allows the liquid to flow along the rotor clear liquid passage 302 and flow through the outer wall of the rotor 1.

Referring to the attached

drawings

1, 6 and 7, a rotor scraper 5 is arranged on the outer periphery of the top of a rotor 1, referring to fig. 5, a stator scraper 6 is arranged on the inner periphery of the bottom of a stator 2, when the rotor 1 and the stator 2 move in a staggered manner, the rotor scraper 5 and the stator scraper 6 scrape materials adhered to the surfaces of the stator 2 and the rotor 1 respectively, referring to fig. 1, in the normal emulsification process of the rotor 1 and the stator 2, the rotor scraper 5 and the stator scraper 6 respectively have certain gaps with the stator 2 and the rotor 1, so that the rotor scraper 5 and the stator scraper 6 are not contacted with the stator 2 and the rotor 1, only when the rotor 1 and the stator 2 move up and down in a staggered manner, the rotor scraper 5 and the stator scraper 6 are contacted with the stator 2 and the rotor 1 respectively, and accordingly the rotor scraper 5 and the stator scraper 6 are prevented from being seriously abraded with the stator 2 and the rotor 1 for a long time in the normal emulsification process.

Referring to fig. 2, a schematic diagram of a state when the rotor 1 and the stator 2 are dislocated with each other in the embodiment is shown, and the principle is as follows: fig. 1 is a schematic diagram showing the positions of a rotor 1, a stator 2, a rotor cleaning box 3 and a stator cleaning box 4 during normal emulsification, when the contact surface between the rotor 1 and the stator 2 needs to be cleaned, a stator telescopic rod 7 is contracted from the state shown in fig. 1, so that the stator 2 drives the rotor cleaning box 3 to move upwards, at this time, the rotor 1 keeps rotating, when the stator 2 ascends, the upper end of the stator 2 is annular and gradually extends into an annular rotor groove 402, liquid entering from an upper liquid inlet 401 enters the rotor groove 402, a stator clear liquid channel 403, the liquid in the rotor groove 402 turns to flow in the stator clear liquid channel 403 due to the blockage of the stator 2 and then tangentially flows through the inner side wall of the stator 2, and therefore, materials on the inner side wall of the stator 2 are washed away; meanwhile, the rotor cleaning box 3 moves upwards along with the stator 2, so that the rotor 1 which is not in the axial position gradually approaches the stator pressing plate 303 and is pressed on the stator pressing plate 303, the spring 304 contracts, and the liquid flow flowing from the lower liquid inlet 301 to the rotor clear liquid channel 302 also flows through the outer side wall of the rotor 1, so that the material on the outer side wall of the rotor 1 is washed away. It should be noted that the material adheres to the milled surfaces of the rotor 1 and the stator 2 under a large force due to the milling extrusion, instead of adhering to the outer walls of the rotor 1 and the stator 2 due to the large viscosity of the material, which is solved by the present embodiment, otherwise the washing effect is not obvious.

Example two: different from the first embodiment, be connected with rotor case telescopic link 9 between rotor cleaning case 3 and the stator 2, stator cleaning installs stator case telescopic link 10 between case 4 and the mounting panel, and stator cleaning case 4 is disconnected with rotor 1, and the middle part that stator cleaning case 4 can use the bearing to be connected with main pivot 8, perhaps sets up the through-hole for main pivot 8 passes from the through-hole, guarantees that rotor 1 and stator cleaning case 4 can not link. In the normal emulsification process, the positions of the rotor 1, the stator 2, the rotor cleaning box 3 and the stator cleaning box 4 are shown in the attached drawing 8, when cleaning is needed, the rotor box telescopic rod 9 is firstly contracted, the stator box telescopic rod 10 is extended, so that the rotor 1, the stator 2, the rotor cleaning box 3 and the stator cleaning box 4 are in the position shown in the attached drawing 1, and then the stator telescopic rod 7 is contracted, the rest process is the same as that of the first embodiment, therefore, when emulsification is carried out, the distance between the rotor cleaning box 3 and the stator cleaning box 4 and the rotor 1 and the length of the stator 2 are larger, the flowing of liquid into the rotor 1 cannot be influenced, and the emulsification process is the same as that in the prior art. In addition, in order to improve the washing effect on the surfaces of the rotor 1 and the stator 2, considering that more materials are emulsified in liquid flow for a certain time and the washing effect is poor, under the permission of the material emulsifying process, a part of solvent can be stored, for example, water is stored in a box body, connecting pipelines are connected to a lower liquid inlet 301 and an upper liquid inlet 401 and are connected into a stored water tank, a water pump is arranged on the pipelines, and when cleaning is carried out, water solution is used for cleaning.
