Centrifugal blending machine

[0023] Example 1: Figure 1 to Figure 6 , a centrifugal mixer, comprising a frame 1, a motor 2, a stirrer 3 and a pot body 4, the motor 2 is installed on one side of the frame 1, and the agitator is arranged coaxially in the frame 1 3 and the pot body 4, the stirrer 3 is installed on the main shaft 10, and includes a pulley 11, a bearing 12, and a blade installation disk 13 in sequence from bottom to top; the bearing 12 is installed in the coaxial line. The upper end of the bearing seat 14 is provided with a basin-shaped oil seal seat box 15 . Specifically, the rotation of the agitator 3 is that the rotation of the motor 2 drives the blade mounting plate 13 on the main shaft 10 to rotate through the rotation of the pulley 11 . The bearing 12 is installed in the bearing seat 14, and the oil seal seat box 15 provided at the upper end is used to install the oil seal to prevent dust from entering the bearing 12 and ensure the normal operation of the equipment. In addition, the outside of the oil seal seat box 15 at the upper end of the bearing seat 14 is the pot body 4, and together they remain stationary. A pot cover 5 is arranged above the pot body 4, the stirrer 3 is driven by the motor 2 through a v-belt, a discharge port 501 is opened on the periphery of the pot body 4, and the middle of the pot cover 5 is rounded There is a powder material nozzle 6 outside the round hole, and a circle of liquid agent flow channel 7 is arranged on the inner side of the lower joint surface of the powder material nozzle 6. The liquid agent flow channel 7 is correspondingly uniformly distributed with a circle of liquid inlet pores 501 on the pot cover 5 . The liquid agent is pressurized to 0.2MPa, which can ensure the incident flow rate and ensure that the material humidity is qualified. Under this pressure, when passing through the liquid inlet pores 501, a good atomized liquid curtain will be formed to ensure the wetting effect.

[0024] During operation, the dry powder material continuously enters the centrifugal mixer through the powder material nozzle 6, and the liquid agent is connected by the liquid agent pipe joint 8, and is sprayed through the liquid agent flow channel 7-liquid inlet fine hole 501 and is driven by the motor 2. The centrifugal force is thrown onto the dry powder material at the periphery of the pot body 4, and after achieving uniform mixing, it falls into the pot body 5 under the action of gravity, and is discharged from the discharge port 401 by the high-speed rotating agitator to complete the wet mixing of the dry powder material. process.

[0025] Example 2: see image 3 and Figure 4 In a centrifugal mixer shown in the figure, finger-shaped scrapers 19 are evenly arranged on the outside of the blade installation disc 13 of the mixer 3, and finger-shaped scrapers 19 are evenly arranged on the inner surface of the blade installation disc 13. The lower scraper 20 and the fan-shaped scraper 9 in the pot body are arranged alternately along the lower scraper 20 and the scraper 9 in the pot body. The finger-shaped pot body installed on the blade installation disc 13 is along the upper scraper 19, and the pot body is along the lower scraper 20 and the fan-shaped scraper 9, in the form of three layers of grinding tools, scraping off the materials adhered to the pot body 4, and After further stirring, it is discharged from the discharge port 401 on the pot body 4 to complete the mixing and stirring. For each layer of grinding knives, take a circle of evenly distributed upper scrapers 19 on the inside of the pot as an example. The upper material is equally divided and hit on the circumference, and the material is agglomerated and broken. Moreover, the three-layer grinding tools have different phases, which can realize the purpose of mixing and stirring the materials on the circumference for many times, so that the materials can be fully and evenly stirred.

[0026] Example 3: see Figure 8 and Figure 9 , a centrifugal mixer, its structure is the same as the previous two examples, on the pot cover 5, a high-pressure air blowing nozzle 21 is installed at the position corresponding to the discharge port 401 of the pot body 4. The high-pressure air of 0.6 MPa is passed through the high-pressure air blowing nozzle 21, which can prevent the material from sticking on the periphery of the discharge port.

[0027] Therefore, the invention has the characteristics of reasonable and simple structure, high degree of automation, high production efficiency, stable product quality, etc., and is suitable for the streamlined production of plastic partition wall slat products, which is beneficial to the expansion of the industry.
