Description

Technical Field

[0001] This utility model relates to the technical field of resin mixing equipment, and in particular to a mixer that can achieve uniform mixing of various fillers and resins. Background Technology

[0002] Mixers for various fillers and resins often encounter problems during operation, such as uneven mixing, filler stratification, and filler agglomeration. Fillers tend to accumulate at the bottom and top of the equipment. Generally, fillers and resins are prone to stratification due to density differences, requiring continuous stirring. However, conventional stirring paddles only rotate and cannot effectively solve this stratification problem. Improved stirring structures, while equipped with upper and lower scraper blades, still tend to cause filler agglomeration. Further mixer designs have introduced screw lifting mechanisms, but these are only suitable for lifting high-density fillers and cannot handle low-density fillers, which tend to accumulate at the top, leading to uneven mixing. Some mixers use screw conveying mechanisms, which are only suitable for conveying low-density fillers and are ineffective for high-density fillers, which tend to accumulate at the bottom, causing blockages. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems by providing a mixer that can achieve uniform mixing of various fillers and resins.

[0004] The technical solution of this utility model is implemented as follows: This utility model provides a mixer capable of uniformly mixing various fillers and resins, the mixer comprising: Tank body; A stirring blade drive rod, the first end of which is rotatably connected to the top cover of the tank, and the second end of which extends into the tank; A guide tube, one end of which is fixedly connected to the top cover of the tank, and the other end extends into the tank body, with a gap between it and the inner bottom surface of the tank body; The stirring blade drive rod has a first helical blade on the outer side inside the guide tube, and a second helical blade on the part extending out of the guide tube. The first and second helical blades rotate in opposite directions, and the part of the guide tube near the top cover of the tank has an opening. The mixer also includes a reflux assembly for guiding the flow of materials in the tank, so that the material flow has a first mode and a second mode; In the first mode, the reflux assembly extracts material from the bottom of the tank and feeds it into the tank from the top; In the second mode, the reflux assembly transports the material at the bottom of the tank from the middle of the tank to the bottom side of the tank. The second end of the stirring blade drive rod extends into the guide tube and from the bottom of the guide tube into the reflux assembly.

[0005] The advantages or beneficial effects of the above technical solutions include at least the following: The agitator forms an 8-shaped circulating mixing pattern, ensuring uniform mixing. The screw of the agitator works in conjunction with the bottom pipeline to pressurize the material to the return pipeline and the feed pipeline, ultimately returning it to the tank. Simultaneously, the delivery pump directly sends the material back to the top of the tank. These two material lifting methods effectively accelerate the rapid circulation of the bottom material, preventing the accumulation of bottom filler. This structure achieves an organic combination of material lifting and pressing. Through the 8-shaped circulating mixing and two bottom lifting methods, it ensures that various fillers and resins can be uniformly mixed, achieving ideal mixing results regardless of whether the filler density is higher or lower than the resin density.

[0012] Reference Figure 1 A mixer capable of uniformly mixing various fillers and resins, the mixer comprising: Tank 10; The stirring blade drive rod 20 has a first end that is rotatably connected to the top cover 11 of the tank 10, and a second end that extends into the tank 10. A guide tube 12 is provided, with one end fixedly connected to the top cover 11 of the tank body 10, and the other end extending into the tank body 10, with a gap between it and the inner bottom surface of the tank body 10. Furthermore, a motor 40 is also installed on the top cover 11 of the tank body 10, with the base of the motor 40 mounted on the top cover 11. The output end 312 of the motor 40 passes through the top cover 11 and enters the guide tube 12, and is fixed to the first end of the stirring blade drive rod 20. The motor 40 is used to rotate the stirring blade drive rod 20. A material distribution platform 121 is also installed on the outside of the guide tube 12. The cross-section of the material distribution platform 121 is arc-shaped, with its arc surface facing the top cover 11 of the tank body 10. Material falling from the top cover 11 will touch the material distribution platform 121, dispersing the material and preventing it from accumulating.

[0013] The stirring blade drive rod 20 has a first helical blade 21 on the outer side inside the guide tube 12, and a second helical blade 22 on the part extending out of the guide tube 12. The first helical blade 21 and the second helical blade 22 rotate in opposite directions. The part of the guide tube near the top cover 11 of the tank 10 has an opening 122. The output end 312 of the motor 40 causes the stirring blade drive rod 20 to rotate, causing the first helical blade 21 and the second helical blade 22 to rotate. The material enters from the gap. Some of the material is rolled into the guide tube 12 by the first helical blade 21 and transported upward, while some of the material is transported downward by the second helical blade 22. The mixer also includes a stirring blade 23, which is fixed to a preset part of the stirring blade drive rod 20. The preset part is the part of the stirring blade drive rod 20 located between the first spiral blade 21 and the second spiral blade 22.

[0014] Furthermore, the mixer also includes a reflux assembly 30, which includes: The first end of the return pipe 31 is connected to the bottom of the tank 10. The second end of the stirring blade drive rod 20 extends into the return pipe 31. The second spiral blade 22 also extends into the return pipe 31 along with the stirring blade drive rod 20. As the motor 40 rotates the drive rod, the second spiral blade 22 rotates, conveying the material to the return pipe 31. The return pipeline 32 has its first end connected to the return pipeline 31 and its second end connected to the bottom of the tank 10. The return pipeline 32 is also equipped with a valve 321, which is used to connect or block the return pipeline 32. The conveying pump 33 is installed on the side of the tank 10. The conveying pump 33 includes a feed end 311 located at a low position and an output end 312 located at a high position. The output end 312 is connected to the top cover 11 of the tank 10 and extends into the tank 10. The second end of the return pipe 31 is connected to the feed end 311. The reflux assembly 30 is used to guide the flow of material within the tank 10, so that the material flow has a first mode, a second mode, and a third mode: In the first mode, valve 321 is closed, transfer pump 33 is turned on, and material is drawn from the bottom of tank 10 and fed into tank 10 from the top; as Figure 2 As shown by the blue arrow, the material enters the return pipe 31 through the gap between the guide pipe 12 and the bottom surface of the tank 10, and is then pumped upward to the top of the tank 10 by the conveying pump 33, which accelerates the rapid circulation of the bottom material back to the top and prevents the bottom packing from accumulating. In the second mode, valve 321 is opened, and conveying pump 33 is closed, allowing material at the bottom of tank 10 to be conveyed from the middle of tank 10 to the bottom side of tank 10; as Figure 2As shown by the red arrow, part of the material is pumped by the first spiral blade 21 into the guide pipe 12 and transported upward until it falls out from the opening 122. Another part of the material is pumped by the second spiral blade 22 into the return pipe 31 and then pumped back into the tank 10 through the return pipe 32, forming a figure-eight-shaped circulation to ensure that the resin and various fillers can be fully circulated and mixed evenly at the bottom and top. In the third mode, both valve 321 and transfer pump 33 are open, a portion of the material at the bottom of tank 10 is drawn out and fed into tank 10 from the top, and a portion of the material at the bottom of tank 10 is transported from the middle of tank 10 to the bottom side of tank 10; for example Figure 3 As shown by the red and blue arrows, some material is pumped by the first spiral blade 21 into the guide pipe 12 and transported upwards until it falls out from the opening 122. Another part of the material is pumped by the second spiral blade 22 into the return pipe 31, and then pumped back into the tank 10 through the return pipe 32, forming a figure-eight-shaped circulation to ensure that the resin and various fillers can be fully circulated and mixed evenly at the bottom and top. At the same time, some material enters the return pipe 31 through the gap between the guide pipe 12 and the bottom surface of the tank 10, and is then pumped upwards to the top of the tank 10 by the delivery pump 33, which accelerates the rapid circulation of the bottom material back to the top and prevents the bottom filler from accumulating.
