Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery drying, in particular to an online supplementary combustion drying system for the lithium battery industry. Background Art

[0002] Battery-grade lithium carbonate refers to high-purity lithium carbonate products that meet battery production requirements. Lithium carbonate is an inorganic compound. The production of battery-grade lithium carbonate, using lepidolite or spodumene as primary raw materials, often presents production challenges due to the variability and uncontrollability of their moisture content.

[0003] During the production of existing battery-grade lithium carbonate, fluctuations in moisture content not only directly affect the efficiency of lithium extraction, but may also lead to increased energy consumption and unstable product quality during the production process. At the same time, the uncontrollability of moisture also has a certain impact on the operation of production equipment. High moisture content may lead to increased corrosion of equipment, increasing equipment maintenance and replacement costs. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the fluctuation of moisture content not only directly affects the lithium extraction efficiency, but also may lead to increased energy consumption and unstable product quality in the production process. At the same time, the uncontrollability of moisture also has a certain impact on the operation of production equipment. High moisture content may cause aggravated corrosion of equipment, increasing the maintenance and replacement costs of equipment. An online supplementary combustion drying system for the lithium battery industry is proposed.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an online supplementary combustion drying system for the lithium battery industry, comprising a combustion chamber, a mixing chamber installed at one end of the combustion chamber, a smoke outlet connected to the side of the mixing chamber, a smoke inlet connected to the side of the mixing chamber, and temperature detection points and flow detection points are provided on the sides of the smoke outlet and the smoke inlet.

[0006] Preferably, a cold air valve is connected to the side of the combustion chamber, and an electronic ignition gun is installed at one end of the combustion chamber.

[0007] Preferably, a fuel inlet is connected to the side of the electronic ignition gun, and an inspection door is installed on the side of the combustion chamber.

[0008] Preferably, a support frame is installed at the bottom of the combustion chamber.

[0009] Compared with the prior art, the advantages and positive effects of the present invention are:

[0010] In the present invention, temperature detection points and flow detection points are set at both the flue gas outlet and the flue gas inlet. When the waste heat temperature inside the combustion chamber does not meet the temperature required for drying the raw materials, supplementary combustion and temperature increase are performed after real-time monitoring. When the flue gas temperature is too high, an appropriate amount of cold air can be added through the cold air valve to achieve the effect of cooling and mixing air. Through the temperature detection points and the flow detection points, important parameters such as temperature, humidity, fuel consumption, etc. can be collected in real time for analysis by operators and automation systems. At the same time, it is beneficial to automatically adjust parameters such as fuel supply, fan speed and drying temperature according to the collected data, which is beneficial to ensure the stability of product quality and avoid product defects caused by uneven drying.

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: Figure 1-Figure 3As shown, the utility model provides a technical solution: an online supplementary combustion drying system for the lithium battery industry, comprising a combustion chamber 5, an air mixing chamber 6 is installed at one end of the combustion chamber 5, a smoke outlet 10 is connected to the side of the air mixing chamber 6, a smoke inlet 11 is connected to the side of the smoke outlet 10 and the smoke inlet 11, a temperature detection point 1 and a flow detection point 2 are provided on the sides of the smoke outlet 10 and the smoke inlet 11, a cold air valve 4 is connected to the side of the combustion chamber 5, an electronic ignition gun 3 is installed at one end of the combustion chamber 5, a fuel inlet 7 is connected to the side of the electronic ignition gun 3, an inspection door 9 is installed on the side of the combustion chamber 5, and a support frame 8 is installed at the bottom of the combustion chamber 5.

[0018] In this embodiment, the combustion chamber 5 uses the waste heat of high-temperature flue gas to dry the raw materials. Temperature detection points 1 and flow detection points 2 are set at the flue gas outlet 10 and the flue gas inlet 11. When the waste heat temperature inside the combustion chamber 5 does not meet the temperature required for drying the raw materials, supplementary combustion and temperature increase are performed after real-time monitoring. When the flue gas temperature is too high, an appropriate amount of cold air can be added through the cold air valve 4 to achieve the effect of cooling and mixing air. The fuel inlet 7 facilitates the addition of fuel, the support frame 8 is conducive to providing stable support for the combustion chamber 5, and the inspection door 9 facilitates internal inspection and maintenance. Real-time monitoring and precise control are the basis of the online supplementary combustion drying system. Through various sensors installed in the system Sensors can collect important parameters such as temperature, humidity, and fuel consumption in real time. These data are transmitted to the central control system through the network for analysis by operators and automation systems. At the same time, real-time monitoring can help detect abnormal situations in time and avoid production losses due to equipment failure or operational errors. Precision control is the core of the online supplementary combustion drying system. According to the real-time monitoring data, the system can automatically adjust the fuel supply, fan speed, drying temperature and other parameters. Precision control can not only improve the drying efficiency, but also effectively reduce energy consumption and reduce environmental pollution. In addition, precise control can also ensure the stability of product quality and avoid product defects caused by uneven drying.

[0019] The working principle of this embodiment is as follows: when in use, the combustion chamber 5 first uses the waste heat of high-temperature flue gas to dry the raw materials. A temperature detection point 1 and a flow detection point 2 are set at the flue gas outlet 10 and the flue gas inlet 11. When the waste heat temperature inside the combustion chamber 5 does not meet the temperature required for drying the raw materials, supplementary combustion and temperature increase are performed after real-time monitoring. When the flue gas temperature is too high, an appropriate amount of cold air can be added through the cold air valve 4 to achieve the effect of cooling and mixing air.
