[0019] Example 1
[0020] Please see Figures 1-3 This utility model provides a raw material homogenization conveying device, including a load-bearing platform 1. A first horizontal mixer 2 is installed on the upper part of the load-bearing platform 1, and a second horizontal mixer 3 is installed on the lower part of the load-bearing platform 1. The discharge end of the first horizontal mixer 2 is connected to the feed end of the second horizontal mixer 3 through a discharge pipe 4. There is a speed difference between the rotational speed of the first horizontal mixer 2 and the second horizontal mixer 3. Due to the speed difference between the first and second horizontal mixers, high-speed mixing and low-speed mixing can be combined, making the physical mixing of materials more uniform and stable, and improving the agglomeration and bridging phenomenon caused by excessive material temperature. It should be understood that, when setting the specific speed of the first horizontal mixer 2 and the second horizontal mixer 3, depending on the different materials being mixed, the speed of the first horizontal mixer 2 can be set to be greater than the speed of the second horizontal mixer 3, or it can be set to be less than the speed of the second horizontal mixer 3.
[0021] Please see Figure 1 and Figure 2The first horizontal mixer 2 includes a first cylinder 21, a first auger 22 rotatably disposed inside the first cylinder 21, and a first variable frequency motor 23 driving the first auger 22 to rotate. The first variable frequency motor 23 is installed on the side of the first cylinder 21, and the feed end of the discharge pipe 4 is disposed at the lower part of the first cylinder 21. The second horizontal mixer 3 includes a second cylinder 31, a second auger 32 rotatably disposed inside the second cylinder 31, and a second variable frequency motor 33 driving the second auger 32 to rotate. The second variable frequency motor 33 is installed on the side of the second cylinder 31, and the discharge end of the discharge pipe 4 is connected to the upper part of the second cylinder 31. In practical use, the operation of the first variable frequency motor 23 drives the first auger 22 to rotate, thereby mixing the material. The mixed material enters the interior of the second cylinder 31 through the discharge pipe 4. The operation of the second variable frequency motor 33 drives the first auger 32 to rotate, mixing the material again. By adjusting the speed of the first variable frequency motor 23 and the second variable frequency motor 33, the speed difference can be adjusted, which can realize the combination of high-speed mixing and low-speed mixing, making the physical mixing of the material more uniform and stable, improving the agglomeration and bridging phenomenon caused by excessive material temperature, achieving a good mixing effect. Moreover, through the relatively closed first cylinder 21 and second cylinder 31, the continuous and stable output of the material can be achieved.
[0022] Please see Figure 1 and Figure 3 The discharge end of the second cylinder 31 is connected to an inclined third cylinder 34. A third auger 35 is rotatably mounted inside the third cylinder 34. A third variable frequency motor 36, which drives the third auger 35, is installed on the upper part of the third cylinder 34. A discharge port 37 is provided at the discharge end of the third cylinder 34. A load-bearing bracket 11 supporting the third cylinder 34 is installed on the side of the load-bearing platform 1 to provide good support for the third cylinder 34. In actual use, the third variable frequency motor 36 drives the third auger 35 to rotate, thereby rotating the discharged material. By adjusting the speed of the third auger 35, the mixing and conveying speed can be linked, providing a stable and continuous material supply. This solves the problem of uneven material delivery to the production equipment, reduces the labor intensity of production personnel, and facilitates employee operation.
[0023] Please see Figure 1 A control box 24 is installed on the side of the first cylinder 21. The control box 24 contains a frequency converter for adjusting the speed of the variable frequency motor, so as to adjust the speed of the variable frequency motor.
[0024] Working principle: During operation, the first variable frequency motor 23 drives the first auger 22 to rotate, thereby mixing the materials. The mixed materials enter the interior of the second cylinder 31 through the discharge pipe 4. The second variable frequency motor 33 drives the first auger 32 to rotate, mixing the materials again. By adjusting the speed of the first variable frequency motor 23 and the second variable frequency motor 33, the speed difference can be adjusted, enabling a combination of high-speed and low-speed mixing. This results in more uniform and stable physical mixing of the materials, improving the bridging phenomenon caused by excessive material temperature and achieving a good mixing effect. The third variable frequency motor 36 drives the third auger 35 to rotate, thereby rotating the discharged materials. By adjusting the speed of the third auger 35, the mixing and conveying speed can be linked, providing a stable and continuous material supply. This solves the problem of uneven material delivery to the production equipment, reduces the labor intensity of production personnel, and facilitates employee operation.
[0025] It should be noted that the model and specifications of the variable frequency motor need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.
[0026] The power supply and operating principle of variable frequency motors are clear to those skilled in the art, and will not be described in detail here.
