Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically to a mixer device for mixing kaolin and water-based carbon black slurry. Background Technology

[0002] Kaolin is a natural clay mineral with kaolinite as its main component. It is named after Gaoling Village in Jingdezhen, Jiangxi Province, China, where it was first discovered. It is characterized by high whiteness, strong plasticity, and good chemical stability, and is widely used in ceramics, papermaking, coatings, rubber, medicine and other fields.

[0003] Waterborne carbon black paste is a uniform paste formed by stabilizing carbon black in an aqueous system through physical or chemical methods. Due to its environmentally friendly and low VOC (volatile organic compound) characteristics, it is widely used in industries such as coatings, inks, plastics, and batteries.

[0004] The composite material formed by mixing kaolin and aqueous carbon black slurry combines the characteristics of both. In terms of conductivity and shielding performance, carbon black can provide an excellent conductive network and reduce volume resistivity, while the sheet-like structure of kaolin can form a physical barrier and enhance the electromagnetic shielding effect. It is usually used as an antistatic coating or an auxiliary material for lithium battery electrodes.

[0005] In terms of mechanical properties, kaolin's nano-scale filler enhances the rigidity of the matrix, while carbon black provides elastomer reinforcement; the combination of the two can balance hardness and toughness. Regarding improved thermal stability, kaolin's high-temperature resistance can delay the thermal decomposition of the substrate, while carbon black's high thermal conductivity aids heat dissipation, making it frequently used in the production of flame-retardant cable coatings and high-temperature sealing materials.

[0006] The mixing process of kaolin and water-based carbon black slurry requires the use of a mixing device. Traditional mixing devices directly mix kaolin, water, and water-based carbon black slurry together in a homogenizer without taking into account the differences in dispersion and viscosity, and without pre-wetting the kaolin. Furthermore, the mixing of water-based carbon black slurry requires a suitable temperature, and without a heating and cooling structure, it is impossible to adjust the mixing temperature in a timely manner. Utility Model Content

[0007] To address the technical problems of traditional mixing devices that fail to consider the differences in dispersion and viscosity, do not pre-wet kaolin, and lack heating and cooling structures to adjust the mixing temperature in a timely manner when mixing water-based carbon black slurry, this invention provides a mixer device for mixing kaolin and water-based carbon black slurry.

[0008] A mixer device for mixing kaolin and aqueous carbon black slurry includes a high-speed mixing chamber, a low-speed mixing chamber connected to the top wall of the high-speed mixing chamber, a cold water chamber inside the side wall of the high-speed mixing chamber, several fixed grinding blocks and several electric heating rods evenly arranged on the inner side wall of the high-speed mixing chamber, rotating grinding rollers arranged in an alternating manner inside the high-speed mixing chamber, a temperature sensor on the high-speed mixing chamber, a spiral stirring rod rotating inside the low-speed mixing chamber, and a feed pipe and a discharge pipe connected to both the low-speed mixing chamber and the high-speed mixing chamber.

[0009] More preferably, the low-speed mixing chamber is fixedly installed on the top wall of the high-speed mixing chamber, and the feed pipe and discharge pipe are fixedly installed through the top and bottom walls of the low-speed mixing chamber and the high-speed mixing chamber, respectively. The top of the feed pipe is movably provided with a cover, and the discharge pipe is provided with a solenoid valve.

[0010] More preferably, water inlet pipes are fixedly installed at the top of the cold water chamber and the top of the low-speed mixing box, respectively. The water inlet end of the water inlet pipe is equipped with a water pipe connector, which can be quickly connected to an external water source. A drain pipe with a cover is fixedly installed at the bottom of the cold water chamber.

[0011] More preferably, both the side wall of the low-speed mixing chamber and the bottom wall of the high-speed mixing chamber are equipped with geared motors via mounting brackets, and both the rotating grinding roller and the spiral stirring roller include a rotating shaft fixedly mounted on the output shaft of the geared motor, wherein the outer wall of the rotating shaft in the spiral stirring roller is fixedly provided with spiral blades.

[0012] More preferably, the outer wall of the rotating shaft in the rotating grinding roller is fixedly provided with two layers of rotating grinding blades, and the two layers of rotating grinding blades are staggered.

[0013] More preferably, several fixed grinding blocks and several electric heating rods are fixedly arranged on the inner side wall of the high-speed mixing chamber, and the several fixed grinding blocks are slidably and friably connected to the outer side wall of the rotating grinding blades. The cross-sectional width of the several electric heating rods is smaller than the cross-sectional width of the several fixed grinding blocks to avoid contact with the rotating grinding blades.

[0014] More preferably, the probe end of the temperature sensor is installed inside the high-speed mixing chamber, the output end of the temperature sensor is installed outside the high-speed mixing chamber, the bottom wall of the high-speed mixing chamber is provided with an arc-shaped structure, the discharge pipe is located at the bottom of the arc-shaped structure, and a receiving box is movably placed below it.

[0015] Compared with the prior art, the beneficial effects of this utility model are: kaolin and water can be pre-mixed in a low-speed mixing box and stirred at low speed (200-500 rpm) to form a slurry base material. After mixing, it enters a high-speed mixing box, and water-based carbon black slurry is added at the same time. The high-speed mixing is increased to more than 2000 rpm to avoid excessive local concentration. At the same time as mixing, it can be heated by an electric heating rod to make it more uniform. The internal temperature is monitored by a temperature sensor. If the temperature is too high, cold water is added to the cold water chamber to cool it down. Attached Figure Description

[0025] A mixer device for mixing kaolin and water-based carbon black slurry includes a high-speed mixing chamber 1, a low-speed mixing chamber 2 connected to the top wall of the high-speed mixing chamber 1, and a feed pipe 9 and a discharge pipe 10 connected to both the low-speed mixing chamber 2 and the high-speed mixing chamber 1. The low-speed mixing chamber 2 is fixedly installed on the top wall of the high-speed mixing chamber 1. The feed pipe 9 and the discharge pipe 10 are fixedly installed through the top and bottom walls of the low-speed mixing chamber 2 and the high-speed mixing chamber 1, respectively. A cover is movably installed at the top of the feed pipe 9, and a solenoid valve 11 is installed inside the discharge pipe 10.

[0026] The low-speed mixing chamber 2 is used to premix kaolin and water at a low speed of 200-500 rpm to form a slurry base. After premixing, it enters the high-speed mixing chamber 1, where water-based carbon black slurry is added for high-speed mixing. The speed is increased to over 2000 rpm to avoid excessively high local concentrations.

[0027] After opening the cover, kaolin can be added into the low-speed mixing box 2 through the feed pipe 9, and water-based carbon black slurry can be added into the high-speed mixing box 1. The bottom end of the discharge pipe 10 on the bottom wall of the low-speed mixing box 2 is set at the top of the high-speed mixing box 1. When the solenoid valve 11 is opened, the premixed kaolin slurry can be fed into the high-speed mixing box 1 through the discharge pipe 10.

[0028] A spiral stirring roller 7 is rotatably installed inside the low-speed mixing box 2. Both the side wall of the low-speed mixing box 2 and the bottom wall of the high-speed mixing box 1 are equipped with a geared motor 15 via a mounting bracket. Both the rotating grinding roller 6 and the spiral stirring roller 7 include a rotating shaft 16 fixedly installed on the output shaft of the geared motor 15. The outer wall of the rotating shaft 16 in the spiral stirring roller 7 is fixedly equipped with spiral blades 17.

[0029] Water inlet pipes 12 are fixedly installed at the top of the cold water chamber 3 and the top of the low-speed mixing box 2 respectively. The water inlet end of the water inlet pipe 12 is equipped with a water pipe connector 13, which can be quickly connected to an external water source. While adding kaolin into the low-speed mixing box 2 through the feed pipe 9, the water pipe connector 13 is used to connect with the external water supply pipe. Then, the water pump on the external water supply pipe is started to deliver the external water source to the water inlet pipe 12 and into the low-speed mixing box 2, so that it is mixed with the kaolin.

[0030] Then start the geared motor 15 to drive the rotating shaft 16 to rotate at low speed. Adjust the speed to the range of 200-500 rpm, which in turn drives the spiral blades 17 to mix the kaolin and water at low speed. After the mixing is completed, open the solenoid valve 11 so that the kaolin slurry is discharged into the high-speed mixing box 1 through the discharge pipe 10.

[0031] The high-speed mixing chamber 1 is rotatably equipped with an alternating rotating grinding roller 6. The outer wall of the rotating shaft 16 in the rotating grinding roller 6 is fixedly equipped with two layers of rotating grinding blades 18, which are arranged alternately. Several fixed grinding blocks 4 and several electric heating rods 5 are fixedly installed on the inner wall of the high-speed mixing chamber 1, and the several fixed grinding blocks 4 are slidably and rubbed against the outer wall of the rotating grinding blades 18.

[0032] The water-based carbon black slurry is fed into the high-speed mixing box 1 through the feed pipe 9. Then, the reduction motor 15 is started, which drives the rotating shaft 16 to rotate at high speed, causing the upper and lower rotating grinding blades 18 to rotate at high speed. This mixes and stirs the kaolin slurry and water-based carbon black slurry at high speed. The upper and lower layers of rotating grinding blades can perform multi-layer stirring of the mixture, so that both the upper and lower layers can be uniformly stirred. The staggered stirring can avoid the dead corners of the stirring. Several fixed grinding blocks 4 slide and rub against the outer wall of the rotating grinding blades 18, making the water-based carbon black slurry and kaolin slurry more finely ground.

[0033] The inner wall of the high-speed mixing chamber 1 is evenly provided with several fixed grinding blocks 4 and several electric heating rods 5. The cross-sectional width of the electric heating rods 5 is smaller than that of the fixed grinding blocks 4 to avoid contact with the rotating grinding blades 18. During grinding and stirring, the electric heating rods 5 can be connected to an external power source to heat the internal liquid, and the temperature can be adjusted to different suitable temperatures depending on the process of the product being produced.

[0034] A temperature sensor 8 is installed on the high-speed mixing chamber 1. The sensing end of the temperature sensor 8 is installed inside the high-speed mixing chamber 1, and the output end of the temperature sensor 8 is installed outside the high-speed mixing chamber 1. The temperature sensor 8 can sense the temperature inside the high-speed mixing chamber 1 and display it on the panel of the output end. The operator can decide whether to continue heating or if the temperature is too high and needs to be cooled down based on the temperature indication.

[0035] A cold water chamber 3 is provided inside the side wall of the high-speed mixing chamber 1, and a covered drain pipe 14 is fixedly installed through the bottom of the cold water chamber 3. If the temperature is too high, the water pipe connector 13 is connected to an external water supply pipe, and then the water pump on the external water supply pipe is started to deliver external water to the inlet pipe 12 and then to the cold water chamber 3 to cool down the high-speed mixing chamber 1. The used warm water can be discharged to the outside through the drain pipe 14.

[0036] The bottom wall of the high-speed mixing box 1 is provided with an arc-shaped structure, the discharge pipe 10 is located at the bottom of the arc-shaped structure, and the receiving box 19 is movably placed below it. The mixed material after mixing can be discharged from the discharge pipe 10 into the receiving box 10 for centralized storage, which is convenient for subsequent use.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
