Description

Technical Field

[0001] This utility model relates to the field of materials processing technology, and in particular to a high-shear mixer. Background Technology

[0002] High-shear mixers, also known as high-shear emulsification pumps or mixing and dispersing pumps, are indispensable key equipment in modern industrial production. They are widely used in industries such as chemical, food, pharmaceutical and cosmetic industries. Their core function is to efficiently emulsify, homogenize, disperse and mix materials through the strong shearing action formed between the high-speed rotating rotor and the fixed stator. Chinese patent CN223381526U discloses a feeding device for a high-shear mixer, which is used to assist feeding and solve the problems of feeding blockage and slow material discharge in high-shear mixers. In actual use, the powder entering the reactor will also have insufficient uniformity, especially when the inner wall is wet, the powder will adhere and affect the overall mixing efficiency. In addition, the powder is also prone to agglomeration and difficulty in dispersion in liquids with poor flowability. Moreover, the high-shear process essentially inputs a large amount of mechanical energy into the material, a large part of which will be converted into heat energy, causing the material temperature to rise rapidly. This is fatal for heat-sensitive materials (such as some pharmaceuticals, biological products, and food), which may lead to the inactivation, denaturation or deterioration of active substances or product deterioration.

[0020] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0021] This embodiment mainly describes the title of the high-shear mixer; please refer to [link / reference]. Figures 1-7 Specifically, a high-shear mixer includes a transmission frame 1; A lifting plate is provided on the top of the transmission frame 1, and a connecting shaft 2 is provided at the bottom of the front end of the lifting plate. A sealing cover 3 is installed at the bottom of the connecting shaft 2. A drive shaft 4 is provided through the sealing cover 3 at the bottom of the connecting shaft 2. A blocking frame 5 for controlling the level of the mixed liquid is provided outside the drive shaft 4. The top of the baffle frame 5 is equipped with several telescopic rods, which pass through the sealing cover 3 and are located at the bottom of the connecting shaft 2. The position of the baffle frame 5 can be adjusted. Several movable end blocks are provided on the outside of the baffle frame 5, and a separator ring 51 is connected to the outer wall of the movable end blocks. Through the adjustable baffle frame and the cutting disc 42, the agglomerated powder can be efficiently dispersed, improving the mixing efficiency and uniformity. The design of the sealing scraper 53 and the separator ring 51 can effectively scrape off the residue on the inner wall and prevent liquid splashing, reducing material loss. The integrated temperature control system can automatically maintain the optimal mixing temperature, ensuring stable product quality. At the same time, the optimized feed inlet position and liquid level control reduce powder adhesion, optimize the entire process management, and achieve clean, efficient and precise mixing operation.

[0022] A further preferred embodiment of this utility model is: Figure 1 and Figure 2 As shown, the sealing cover 3 is provided with several conveying pipes, and the inlet position of the conveying pipes is set at the inner ring position of the partition ring 51, which can reduce the adhesion of the material to the inner wall, control the discharge position of the powder, and reduce the impact on the efficiency of subsequent mixing and processing.

[0023] A further preferred embodiment of this utility model is: Figure 3 As shown, a docking seat 43 is movably arranged at the bottom of the drive shaft 4. Several positioning rods are arranged between the top of the docking seat 43 and the blocking frame 5. The drive shaft 4 is rotatably arranged inside the blocking frame 5. A set of symmetrically arranged cutting blades 42 are arranged at the bottom of the drive shaft 4. As the drive shaft 4 starts to rotate, it can agitate the liquid inside and start to flow. With the help of the symmetrically arranged cutting blades 42, the situation where large pieces of powder agglomerate inside during the mixing process affects the mixing efficiency can be reduced.

[0024] A further preferred embodiment of this utility model is: Figure 3 and Figure 5 As shown, a rotating ring 41 is connected to the bottom of the extension shaft of the baffle frame 5. The rotating ring 41 is sleeved on the outside of the drive shaft 4. A support ring 52 is provided at the top of the partition ring 51. Several sealing scrapers 53 are clamped at the bottom of the support ring 52. The edges of the sealing scrapers 53 are elastic and fit against the inner wall of the mixing tank to reduce residue. During the mixing process, the height of the mixed liquid level is controlled by the rotation speed of the drive shaft 4. When the rotation speed of the drive shaft 4 changes, the partition ring 51 can be driven to move up and down under the action of the suspension shaft 54. The sealing scrapers 53 can clean the inner wall of the mixing tank to reduce residue. The partition ring 51 can also reduce the splashing of liquid onto the inner wall of the mixing tank and reduce the adhesion of some solid material to the inner wall.

[0025] A further preferred embodiment of this utility model is: Figure 3 and Figure 4The partition ring 51 shown has several fixing holes, and a suspension shaft 54 ​​is installed inside the fixing holes.

Under the action of the temperature sensing component, the internal mixing stability can be fed back. When the temperature changes, the processor can feed back to the temperature control component 511 to maintain the mixing temperature within the corresponding range and reduce the impact on the processing quality.

[0026] A further preferred embodiment of this utility model is: Figure 4 As shown, the bottom of the suspension shaft 54 ​​is made of metal and can be connected to several heat-conducting plates. An isolation ring is provided on the top outer wall of the suspension shaft 54, and several air pressure rings are provided outside the isolation ring.

During the stirring and mixing process, the liquid can impact the bottom of the separating ring 51 and drip along the guide plate between the discrete shafts 581. With the help of the discrete shafts 581, it can impact the condensed powdery material, which can make it spread quickly and reduce the situation where the mixing efficiency is low due to the poor fluidity of the mixed liquid in the subsequent mixing process.

[0028] A further preferred embodiment of this utility model is: Figure 7 As shown, a number of elastic rings are provided on the discrete shaft 581, and the elastic rings are evenly arrayed on the outer wall of the discrete shaft 581. During the mixing process, the powdery material accumulated on the liquid surface can be dispersed by the discrete shaft 581. The mixed liquid can remain on the elastic rings. The powdery material in the feeding process adheres to its surface during the flying process, and the material can be quickly mixed during the subsequent continuous impact of the mixed liquid.

[0029] A further preferred embodiment of this utility model is: Figure 1As shown, a connecting seat 11 is provided at the bottom of the transmission frame 1. A power distribution cabinet is connected to one side of the connecting seat 11, and several positioning plates are provided on the other side of the connecting seat 11 to limit the position of the mixing tank and to assist in positioning, thereby reducing the possibility of unstable docking of the sealing cover 3.
