[0009] like Figure 1 As shown, a viscous material conveying system includes a raw material tank 1, which is provided with a feed port 2 and a discharge port 3. The feed port 2 is connected to the raw material barrel 4, and the raw material tank 1 is connected to the terminal device 6 through a diaphragm pump 5. Due to the controllability of the diaphragm pump conveying, automatic metering is achieved, which effectively improves the feeding accuracy and ensures the accuracy of material conveying and feeding, thereby effectively improving the quality of the finished material.
[0010] The raw material tank 1 is connected to a weighing module or a floor scale 7 to realize automatic measurement, perform accurate measurement, and improve the accuracy of material filling.
[0011] A low-speed stirring device 8 is provided in the raw material tank 1 to prevent material sedimentation.
[0012] The raw material tank 1 is connected to the terminal device 6 through the diaphragm pump 5 and the feeding pipe 9. The raw material tank 1 is provided with a reflux port 10, which is connected to the feeding pipe 9 through the reflux pipe 11 and connected to the terminal device 6. The reflux pipe 11 is provided with a back pressure valve 12. By adding a back pressure valve in front of the terminal device (such as a homogenizer), it is ensured that the entire pipeline is always full of materials, the pipeline is fully sealed for transportation, and the material is prevented from contacting with the air and oxidizing, thereby improving the material storage time.
[0013] The raw material tank 1 is also provided with a nitrogen port 13 and a vacuum port 14 to ensure the feeding of the raw material tank.
[0014] A suction pump 15 and a discharge valve 16 are sequentially arranged between the diaphragm pump 5 and the discharge port 2. The discharge valve at the bottom of the raw material tank is opened, and the material is transported to the terminal equipment through the suction pump and the diaphragm pump, ensuring smooth raw material transportation.
[0015] The feed port 2 is connected to the raw material barrel 4 via a raw material delivery pipe 17 , and a compressed air delivery device 18 is provided on the raw material delivery pipe 17 to ensure stable delivery of the raw materials.
[0016] A coarse filter 19 is provided on the raw material conveying pipe 17, and a fine filter 20 is provided on the feeding pipe 9, which ensures the quality of the raw materials and thus the quality of the subsequent finished products.
[0017] In this embodiment, the terminal equipment is a homogenizer, a feeder for producing lithium battery products, etc.
[0018] The entire system workflow in this embodiment is as follows:
[0019] Step 1: The material is transported into the raw material tank 1 through a suction pump 15 and a diaphragm pump 5. The raw material tank is equipped with a low-pressure stirring device to prevent material sedimentation.
[0020] Step 2: When the terminal device 6 needs to add materials, the discharge valve 16 at the bottom of the raw material tank 1 is opened, and the material is transported to the terminal device 6 through the diaphragm pump 5. The raw material tank 1 is equipped with a weighing module or a floor scale 7 to achieve accurate measurement of the raw materials.
[0021] The present invention and its embodiments are described schematically above. This description is not restrictive.
