Description

Technical Field

[0001] The utility model relates to the technical field of material mixing and drying, in particular to a conical mixer capable of quickly drying materials. Background Technique

[0002] In recent years, the lithium battery industry in China has developed rapidly and has achieved a global leading advantage. As of the end of 2023, the total output of lithium batteries in the country exceeded 940 GW. Along with the continuous enrichment of the application scenarios of lithium batteries, various types of lithium battery production technologies have emerged in an endless stream. In China, resources such as lithium, nickel, and cobalt are relatively scarce, and the sources of these materials mainly rely on imports. Therefore, it has become crucial to develop a battery technology that does not rely on imported resources. Among many alternative battery technology solutions, sodium-ion batteries have stood out. However, in the production process of the negative electrode material of sodium-ion batteries, the drying process of the washed materials often affects the production capacity of the entire production line due to the long drying time. Therefore, shortening the drying time of the washed materials is a key link in breaking through the production technology of the negative electrode material of sodium-ion batteries.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0017] As Figure 1 shown, the conical mixer capable of quickly drying materials in this embodiment includes a conical mixer 1, a dust collector 2, a condenser 3, a liquid collection tank 4 and a water ring vacuum pump 5. A first jacket 6 is arranged on the outer wall of the conical mixer 1, and an exhaust port 7 is arranged above the right side of the conical mixer 1. The dust collector 2 is installed on the exhaust port 7, and a second jacket 8 is arranged on the outer wall of the dust collector 2. A heat-conducting oil is circulated and pumped into the first jacket 6 and the second jacket 8. The first jacket 6 can heat the materials stirred in the conical mixer 1 and quickly evaporate the water rich in the materials; the second jacket 8 can heat the air discharged from the exhaust port 7 and is conducive to the dust collector 2 capturing the dust in the evaporated air. The exhaust end of the dust collector 2 is communicated with the inlet of the condenser 3, the bottom drainage end of the condenser 3 is installed on the liquid collection tank 4, the air discharge port of the condenser 3 is connected with the water ring vacuum pump 5, and cooling water is circulated and pumped into the condenser 3 and the water ring vacuum pump 5.

[0018] Furthermore, a material temperature transmitter 9 and a jacket temperature transmitter 10 are installed on the conical mixer 1. The material temperature transmitter 9 and the jacket temperature transmitter 10 are respectively used to detect and control the material temperature and the heating oil temperature.

[0019] Furthermore, a drain port 11 is provided at the bottom of the liquid collection tank 4.

[0020] Working principle: Materials are added from the feed port of the conical mixer 1. Heating oil is introduced into the first jacket 6 on the outer wall of the conical mixer 1 to quickly discharge the volatilized moisture, accelerating the drying process. Heat-conducting oil is introduced into the second jacket 8 at the outer wall position of the dust collector 2. The dust discharged from the exhaust port 7 of the conical mixer 1 is captured by the filter bag of the dust collector 2 and then falls back into the conical mixer 1. The temperature of the heat-conducting oil is controlled by the jacket temperature transmitter 10.

[0021] For the materials being dried in the conical mixer 1, the material temperature can be monitored in real time through the material temperature transmitter 9, and the materials meeting the drying requirements are discharged from the discharge port at the bottom of the conical mixer 1.

[0022] The clean gas after being treated by the dust collector 2 enters the condenser 3. The air cooled by the condenser 3 and the condensed water enter the liquid collection tank 4. The air enters the water ring vacuum pump 5 from the liquid collection tank 4, and the water can be regularly discharged from the drain port 11 at the bottom of the liquid collection tank 4.

[0023] The air discharged from the water ring vacuum pump 5 after being cooled is connected to the tail gas treatment system supporting the negative electrode production line and can be discharged into the atmosphere only after being treated qualified.
