Description

Technical Field

[0001] This utility model belongs to the field of kaolin mud treatment technology, and in particular relates to a homogenization processor for kaolin mud. Background Technology

[0002] Kaolin is one of the world's four major non-metallic minerals. It is a type of clay and clay rock mainly composed of kaolinite group clay minerals. It is widely distributed in my country, spanning both northern and southern regions, but its reserves are relatively concentrated, with the south having the largest reserves. Kaolinite group clay minerals are formed by the weathering of feldspar or other silicate minerals in igneous and metamorphic rocks in acidic media lacking alkali and alkaline earth metals. Kaolin has excellent properties and a wide range of applications. It possesses advantages such as high whiteness, fine particle size, strong covering power, fast adsorption speed, good acid and alkali resistance, and stable physicochemical properties. Processed kaolin products are widely used in various industries including papermaking, architectural coatings, plastics, high-grade ceramics, and petrochemicals. In the production and processing of kaolin, the homogenization of the slurry is a crucial step, directly affecting the quality and performance of the final product. Chinese utility model CN209869003 U discloses a kaolin slurry conditioning and mixing tank for glass fiber manufacturing. The mixing tank has a stirring shaft in the middle, and the upper end of the stirring shaft passes through a support seat and is connected to the output end of a reducer. Multiple first stirring rods are provided at the lower end of the stirring shaft, and multiple rollers are connected to the first stirring rods. Each roller rests on the bottom of the mixing tank. The bottom of the mixing tank is conical, and a slurry receiving trough is connected to the bottom of the mixing tank. The above device is only suitable for stirring and conditioning kaolin at low speed and cannot be adapted to the treatment of kaolin slurry with different process concentrations. Summary of the Invention

[0003] The technical problem solved by this utility model is that the existing kaolin slurry homogenization device has low efficiency, high energy consumption, and poor homogenization efficiency, and cannot adapt to the treatment of kaolin slurry with different process concentrations.

[0004] This utility model provides a homogenization processor for kaolin slurry, including a homogenization chamber, a shearing assembly, and a flow control assembly. The homogenization chamber has an inlet pipe and an outlet pipe on both sides, and a top cover on its upper end. The shearing assembly includes a drive motor, a stator, and a rotor. The drive motor is fixedly connected to the middle of the upper end of the top cover, and its output shaft passes through the top cover and connects to the drive end of the rotor. The lower end of the rotor has a gap from the bottom surface of the homogenization chamber. The stator is fixed to the bottom surface of the homogenization chamber. The flow control assembly includes a solenoid valve and a first pressure sensor located in the inlet pipe, a second pressure sensor located in the outlet pipe, and a controller. The controller's input terminal is electrically connected to the first and second pressure sensors, and its output terminal is electrically connected to the solenoid valve.

[0005] Furthermore, if the difference between the first pressure sensor and the second pressure sensor is less than a preset value P1, the controller controls the solenoid valve to open more; if the difference between the first pressure sensor and the second pressure sensor is greater than a preset value P2, the controller controls the solenoid valve to open less.

[0006] Furthermore, the rotor includes a rotating base, with a connecting shaft at the upper end of the rotating base, the connecting shaft being connected to the output shaft of the drive motor, and a plurality of upper shear columns at the lower end of the rotating base. The plurality of upper shear columns are arranged in two layers at intervals along the circumference of the rotating base, with the inner layer of upper shear columns being longer than the outer layer. The stator includes a fixed base, the fixed base being connected to the bottom surface of the homogenization treatment chamber, and a plurality of lower shear columns at intervals along the circumference of the upper end surface of the fixed base. The lower shear columns are arranged between the inner and outer layers of upper shear columns.

[0007] Furthermore, it also includes a flow meter installed in the inlet pipe, which is connected to the controller input.

[0008] Furthermore, the top cover is connected to the homogenization chamber by bolts.

[0009] Furthermore, the drive motor is an AC variable frequency motor.

[0010] Furthermore, the homogenization chamber is cylindrical, and the inner wall of the homogenization chamber is coated with a wear-resistant alloy.

[0011] Furthermore, the stator and rotor are made of 304 stainless steel.

[0012] This invention has the following beneficial effects: The shearing component installed in the homogenization chamber can adjust its rotation speed according to different process requirements and material characteristics to adapt to the treatment of kaolin slurry with different process concentrations. It uses mechanical action to quickly disperse and refine the particles in the kaolin slurry, achieving homogenization, dispersion, and emulsification, significantly improving the uniformity and stability of the slurry. When applied before the spraying section, it effectively improves the quality of sprayed products and reduces the frequency of nozzle clogging. At the same time, by installing pressure sensors in the inlet and outlet pipes of the homogenization chamber, the pressure changes inside the chamber can be monitored at all times. The opening of the solenoid valve can be adjusted by the controller to control the slurry flow rate and optimize the homogenization effect. Attached Figure Description
