Description

Technical Field

[0001] This utility model relates to the field of colloid mill technology, and specifically to a colloid mill. Background Technology

[0002] Colloid mills are ultrafine grinding equipment widely used in the food, chemical, pharmaceutical, and daily chemical industries. They are mainly used for the refining, dispersion, emulsification, homogenization, and mixing of liquid or semi-liquid materials. Traditional colloid mills typically employ a stator-rotor structure, generating strong shearing forces, friction, and liquid flow impacts through high-speed rotation to achieve the purpose of refining and homogenizing materials. However, most existing colloid mills have the following shortcomings: First, the stator-rotor gap adjustment method is relatively coarse, lacking sufficient adjustment precision, making it difficult to flexibly set the optimal gap according to material characteristics, thus affecting the grinding fineness and consistency. Second, the equipment easily generates high heat during continuous high-speed operation. If cooling measures are inadequate, the material's properties may change due to temperature rise, such as emulsification, stratification, viscosity changes, or deactivation, reducing product quality. Third, in the structural design of traditional colloid mills, the connection methods of some transmission components or grinding components are complex and unstable, easily leading to misalignment or loosening after long-term operation, affecting grinding efficiency and equipment lifespan.

[0003] In view of the above, the colloid mill proposed in this application is used to solve the above problems. By optimizing the grinding components, cooling system and transmission structure, high-precision control of the stator-rotor gap is achieved. At the same time, it is equipped with an efficient cooling channel to effectively solve the process impact caused by high temperature rise. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0028] This application proposes a colloid mill, the specific details of which are as follows:

[0029] For reference Figure 1This application is mainly completed by the cooperation of the base 1, the machine body 2, the grinding component 3 and the transmission component 4. Through the movement between the above structures, the problem of controllable output size is achieved, and the machine body is cooled by the circulation of coolant to prevent the material from generating high temperature during the grinding process at high speed, which would affect the stability of the material.

[0030] For reference Figure 1 The base 1 is used to fix and support the various units of the machine body 2, the grinding assembly 3, and the transmission assembly 4.

[0031] For reference Figure 1-2 The machine body 2 includes a housing unit 21, an adjusting ring 22, a drive shaft 23, a feed flange 24, and a mechanical seal seat 25; the adjusting ring 22 is threadedly connected to the housing unit 21 and connected to the drive shaft 23; the feed flange 24 is located on the housing unit 21; and the mechanical seal seat 25 is installed on the upper end face of the base 1.

[0032] Furthermore, the housing unit 21 includes a locking housing 211, a spacer housing 212, and a discharge port housing 213. The discharge port housing 213 is installed on the upper end face of the mechanical seal seat 25, the spacer housing 212 is installed on the upper end face of the discharge port housing 213, and the locking housing 211 is installed on the upper end face of the spacer housing 212. Specifically, the adjusting ring 22 is connected to the locking housing 211 by a threaded connection. When the adjusting ring 22 rotates, it moves axially and drives the stator 32 to rise and fall axially through the connecting structure, so as to realize the gap adjustment between the stator 32 and the fixed rotor 31.

[0033] The rotation of the adjusting ring 22 is achieved through the drive shaft 23, which includes a dial indicator 231 and a handwheel 232. The dial indicator 231 is mounted on the top of the feed flange 24 and is used to measure the gap between the rotor 31 and the stator 32. The handwheel 232 is mounted on one side of the feed flange 24. By rotating the handwheel 232, the adjusting ring 22 can be rotated. The adjusting ring 22 can rise or fall, changing the gap between the rotor 31 and the stator 32 during the rise and fall. The gap can be flexibly adjusted and can be adjusted to the most suitable gap for grinding according to process requirements.

[0034] For reference Figure 1-2 The housing unit 21 has grooves inside, specifically the locking housing 211, the partition housing 212, and the discharge housing 213. The discharge housing 213 has a water inlet 5 on one side and a water outlet 6 on the top of the feed flange 24. This forms the inlet and outlet channels of the equipment cooling system. The coolant enters from the water inlet 5 and, when it flows through the grooves, it carries away the heat generated by the grinding material to prevent the material from generating high temperatures during the grinding process at high speeds, which would affect the stability of the material. Finally, it flows out from the water outlet 6.

[0035] For reference Figure 1 The grinding assembly 3 includes a rotor 31, a stator 32, and a connector 33 for connecting the two. Both the rotor 31 and the stator 32 are tapered and have multiple tooth grooves on their surfaces. The tooth grooves are arranged from top to bottom along the axial direction in a manner from coarse to fine, and different tooth grooves have different shapes and orientations. Through the opposite arrangement of tooth grooves, strong turbulence can be generated during the rotation of the rotor 31, thereby significantly improving the grinding efficiency and homogenization effect of the material.

[0036] The connector 33 is connected to the rotor 31. Structurally, it is used to support and stably install the rotor, ensuring that a stable and adjustable coaxial grinding gap is formed between it and the stator. It also has the functions of locking and limiting, preventing loosening, and ensuring stability during high-speed operation. Furthermore, the connecting component 33 includes a pressure plate 331, a bushing 332, and a gland 333. The pressure plate 331 is installed on the upper end face of the mechanical seal seat 25 to ensure the mechanical strength and structural rigidity of the rotor 31 during high-speed operation. The rotor 31 is installed on the upper end face of the pressure plate 331, and the bushing 332 is installed on the upper end face of the rotor 31 to provide axial extension support and maintain the coaxial stability of the rotor 31 system. The gland 333 is installed on the upper end face of the bushing 332 to assist in the sealing and pressing of the bushing 332. The stator 32 is installed on the locking housing 211 through a smooth rod. When the adjusting ring 22 rotates to adjust the up and down position of the stator 32, the position of the rotor 31 fixed by the connecting component 33 remains unchanged, thereby realizing the controllable adjustment of the rotor-stator gap, which helps to achieve control of different grinding fineness.

[0037] For reference Figure 1 The transmission assembly 4 is supported by bearings and limited by end caps to ensure the stable rotation of the transmission shaft. It also uses pulleys to achieve external power input, thereby providing a continuous and reliable power source for the grinding assembly 3 above. Specifically, the transmission assembly 4 consists of an upper bearing end cap 41, a deep groove ball bearing 42, a transmission shaft 43, a lower bearing end cap 44, and a pulley 45. The deep groove ball bearing 42 is located in the bearing position of the base 1 to fix the transmission shaft 43. The transmission shaft 43 is installed inside the base 1 and is vertically installed inside the base 1. The upper bearing end cap 41 and the lower bearing end cap 44 are respectively located on the opposite side of the deep groove ball bearing 42. The pulley 45 is installed at the lower end of the transmission shaft 43.

[0038] Furthermore, the deep groove ball bearing 42 is installed in the bearing position of the base 1 to stabilize and support the rotational movement of the drive shaft 43, ensuring its smooth operation and precision. The upper bearing end cover 41 and the lower bearing end cover 44 are respectively installed on both sides of the deep groove ball bearing 42 to limit and protect the bearing, prevent axial movement, and ensure that the drive shaft is correctly positioned in the bearing. The drive shaft 43 is vertically installed inside the base 1 as the main shaft for power transmission, used to effectively transmit the driving force of the motor or external drive source to the upper grinding assembly or other working parts through the pulley 45. The pulley 45 is installed at the lower end of the drive shaft 43 and can cooperate with the belt or other transmission device to realize the input of external power, drive the drive shaft to rotate, and thus drive the entire grinding system to operate.

[0039] In this invention, the working steps of the device are as follows:

[0040] First, the material to be processed is injected into the equipment through the feed flange 24. At this time, it is necessary to confirm that the inlet 5 and the outlet 6 are connected to the external coolant circulation system. The coolant enters from the inlet 5, flows through the groove structure in the outlet box 213, the partition box 212 and the locking box 211, and finally flows out from the outlet 6 to complete the cooling circuit, so as to ensure the temperature stability of the material during the grinding process.

[0041] After the equipment is started, the external motor drives the transmission shaft 43 installed inside the base 1 to rotate through the belt and pulley 45. The transmission shaft 43 is precisely positioned by the support structure set in the deep groove ball bearing 42, and is limited by the upper bearing end cover 41 and the lower bearing end cover 44 to ensure stability and axial locking during high-speed rotation, thereby transmitting the rotational power to the rotor 31 installed on the pressure plate 331.

[0042] During rotation, the rotor 31 cooperates with the stator 32, which is mounted on the locking housing 211 via a smooth rod, to form a grinding unit. The surfaces of both are provided with tooth groove structures arranged from coarse to fine along the axial direction, with different shapes and directions. When the material passes through the gap between the rotor and the stator, strong turbulence is generated, achieving step-by-step shearing and refinement, which significantly improves grinding efficiency and homogenization effect.

[0043] To meet different material or process requirements, users can adjust the adjustment ring 22 by using the handwheel 232 installed on one side of the feed flange 24 as needed. After rotating the handwheel 232, the adjustment ring 22 will be rotated through the connected drive shaft 23. Since the adjustment ring 22 and the locking housing 211 are connected by a threaded connection structure, the adjustment ring 22 will move axially after rotating, and further drive the stator 32 to rise and fall axially through the connection structure, thereby achieving precise adjustment of the gap between the stator and the fixed rotor 31.

[0044] During the grinding process, the equipment cooling system works continuously. The coolant flows through the annular groove in the housing unit 21, which can effectively absorb and remove the heat generated by material shearing and friction, and prevent the material from changing its properties due to temperature rise. After the material reaches the target particle size and uniformity, it is discharged from the lower discharge port, thus completing the entire grinding operation process.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
