[0019] Due to the angle of the drawing, some parts may not be drawn, but their positions and connections can be understood from the text descriptions.
[0020] like Figure 1 As shown, this utility model is a high-efficiency mixer dispersion system. In the first embodiment, the high-efficiency mixer dispersion system includes a feeding device 11. The output end of the feeding device 11 is connected to the feeding port of the mixer 12. The discharge port of the mixer 12 is connected to the inlet of the slurry cooler 22 through the rotor pump 23. The discharge port of the slurry cooler 22 is connected to the disperser 21. The disperser 21 is connected to the inlet of the mixer 12.
[0021] In this embodiment, as Figure 2 As shown, the feeding device 11 includes a feeding shell with a feed inlet at the top and a discharge outlet 113 at the bottom. A rotating shaft 111 is vertically mounted inside the feeding shell, and several stirring arms 112 are mounted on the rotating shaft 111 from top to bottom. During operation, the raw material is transported from the storage tank to the feeding device 11. The rotating shaft 111 of the feeding device 11 rotates, driving the stirring arms 112 to rotate. The ends of the stirring arms 112 have scrapers that can scrape off the raw material adhering to the inner wall, preventing raw material bridging and facilitating raw material discharge. The raw material can also be premixed. The premixed powder falls into the planetary mixer 12 through a rotary feeder.
[0022] In this embodiment, as Figure 3 As shown, the mixer 12 is a planetary mixer 12. A stirring paddle 121 and a dispersing disc 124 are respectively mounted on the stirring shaft of the planetary mixer 12. A mixing container 122 is placed below the stirring shaft of the planetary mixer 12, and a mixing outlet 123 is provided at the bottom of the mixing container 122. During operation, the stirring paddle 121 and the dispersing disc 124 in the planetary mixer 12 revolve around the central shaft, and in addition to revolving around the central shaft, the stirring paddle 121 and the dispersing disc 124 rotate on their own axes at different speeds, mixing the powder and liquid materials in the mixing container 122.
[0023] In this embodiment, the slurry cooler 22 includes a cooling pipe, and the outer periphery of the cooling pipe is a cooling medium.
[0024] In Example 1, the raw materials are transported from the storage tank to the feeding device 11 for pre-stirring, and then enter the mixer 12 for mixing. The slurry is then pumped by the rotor pump 23 and cooled by the slurry cooler 22 before entering the disperser 21. After dispersion, it enters the mixer 12 again for mixing, and the above steps are repeated to accelerate the dispersion efficiency of the slurry.
[0025] like Figure 4 As shown in Embodiment 2, to increase the working efficiency of the dispersion system, a secondary mixing mechanism is connected between the mixer 12 and the rotor pump 23 via a primary tee 25. The first and second ends of the primary tee 25 are connected to the discharge port of the mixer 12 and the rotor pump 23, respectively. The third end of the primary tee 25 is connected to the secondary mixing mechanism.
[0026] The secondary mixing mechanism includes a slurry circulation tank 34 and a secondary tee 26. The output end of the slurry circulation tank 34 is connected to the input end of the second rotor pump 33. The output end of the second rotor pump 33 is connected to the first end of the secondary tee 26. The second end of the secondary tee 26 is connected to one end of the second slurry cooler 32. The other end of the second slurry cooler 32 is connected to the input end of the second disperser 31. The output end of the second disperser 31 is connected to the input end of the slurry circulation tank 34. The third end of the secondary tee 26 is connected to the third end of the primary tee 25.
[0027] In Example 2, the raw materials are transported from the storage tank to the feeding device 11 for pre-mixing, then enter the mixer 12 for mixing. The slurry is then pumped by the rotor pump 23, cooled by the slurry cooler 22, and enters the disperser 21. After dispersion, it re-enters the mixer 12 for mixing, and the above steps are repeated to accelerate the primary dispersion efficiency of the slurry. The second rotor pump 33 is started, and the slurry is pumped through the second rotor pump 33 to the circulation tank 34 until all the slurry in the planetary mixer 12 is pumped into the circulation tank 34. At this time, the feeding device 11 adds the next batch of raw materials for primary mixing.
[0028] After confirming that the slurry has completed primary mixing and has entered the circulation tank 34, the rotor pump 33 is reversed. The slurry enters the slurry cooler 22 through the second rotor pump 33. After cooling, it enters the second disperser 31 for secondary mixing. After completion, it is fed into the circulation tank 34, and the above process is repeated.
[0029] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
