Description

Background Art

[0002] A kneading pot is a commonly used kneading equipment, which mainly includes a pot body, a stirring blade and a stirring motor that drives the stirring blade. When preparing carbon paste, the stirring blade mixes the carbon particle dry material and the binder (usually asphalt) evenly at a certain temperature.

[0003] Kneading temperature and kneading time are important parameters that affect the kneading quality. If the kneading temperature is not enough, the asphalt viscosity is large, which may easily cause uneven kneading, poor plasticity of the paste, dry material inclusions, low green body bulk density, uneven internal structure of carbon products after roasting, and poor mechanical properties. If the kneading temperature is too high, the asphalt will decompose and volatilize due to heat, and a condensation reaction will occur, resulting in poor plasticity of the paste and even waste. If the kneading time is too short, the paste is not mixed evenly and dry material inclusions may occur easily. If the kneading time is too long, the effect of enhancing the mixing uniformity is small, but the large particles will be destroyed, resulting in low green body bulk density, low strength, and increased energy consumption of the kneading pot.

[0004] At present, the kneading quality is mainly ensured by controlling the kneading temperature and kneading time. On the one hand, it is determined whether the kneading temperature and kneading time meet the production regulations. On the other hand, the quality of the green body is detected and the kneading temperature and kneading time are dynamically adjusted. However, the above method has the following defects:

[0005] (1) It takes a certain amount of time to detect the quality of the green billet, which makes the dynamic adjustment of the kneading temperature and kneading time hysteresis, which easily increases the amount of unqualified green billets, reduces production efficiency and increases energy consumption;

[0006] (2) In the actual production process, due to factors such as equipment and measurement, there is an error between the amount of material added to the kneading pot and the required amount. If the error is large, the kneading temperature and kneading time are not adjusted in time, which will easily affect the kneading quality. Summary of the invention

[0007] The embodiments of the present application provide a kneading quality determination method, device, medium, and kneading pot, which are used to solve the technical problem that it is difficult to ensure the kneading quality by controlling the kneading temperature and kneading time.

[0046] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0047] Figure 1 A flow chart of a method for determining kneading quality in an embodiment of the present application is shown. Figure 1, a kneading quality determination method is provided, which is applied to a kneading pot, wherein the kneading pot comprises a stirring blade for kneading carbon paste and a stirring motor for driving the stirring blade, the kneading pot further comprises a reducer and a pot body, the stirring motor is connected to the stirring blade via the reducer, and the stirring blade is arranged in the pot body, the method comprises at least S1 to S3, which are described in detail as follows:

[0048] In step S1, a power extreme difference threshold is obtained, wherein the power extreme difference threshold represents a threshold of a power extreme difference.

[0049] In some embodiments, obtaining the power range threshold includes: determining the power range threshold based on a preset target relationship and the binder content of the carbon paste, wherein the target relationship is a positive relationship between the binder content and the range threshold, that is, the higher the binder content, the higher the range threshold.

[0050] In step S2, the current power range difference of the stirring motor within the cycle time is determined. The cycle time can be the time for the stirring blade to stir for one cycle, or the time for the stirring blade to stir for N cycles, where N is a positive integer greater than or equal to 2, or a preset time. The current power range difference is the power range difference within the time range between the current moment and the previous moment, and the previous moment after the cycle time is the current moment.

[0051] In step S3, if the current power range difference is less than or equal to the power range difference threshold, it is determined that the kneading quality of the carbon paste meets the first preset requirement. The first preset requirement may be that the kneading uniformity is greater than a preset degree, or that the kneading uniformity meets the kneading completion requirement.

[0052] In this way, the raw materials of the carbon paste are added into the pot body, the pot body is heated, and the stirring motor drives the stirring blade to rotate after being slowed down by the reducer. The stirring blade drives the raw materials of the carbon paste to flip and knead, that is, the raw materials of the carbon paste are mixed and kneaded. The working power of the stirring motor is related to the force applied to the stirring blade when it rotates. The greater the force applied to the stirring blade, the greater the working power of the stirring motor, that is, the working power of the stirring motor is positively correlated with the force applied to the stirring blade. In the initial stage of kneading, the raw materials of the carbon paste are in an uneven state, and the force difference of the stirring blade at different positions is large, resulting in a large difference in the working efficiency of the stirring motor, that is, a large power range. As the kneading proceeds, the raw materials of the carbon paste change from an uneven state to a uniform state, and the force difference of the stirring blade at different positions decreases, resulting in a decrease in the working efficiency difference of the stirring motor and a decrease in the power range. When the raw materials of the carbon paste become uniform, the working efficiency difference of the stirring motor is small or even close to 0, and the power range is less than or equal to the power range threshold. In other words, when the raw materials of the carbon paste tend to be mixed evenly, the first preset requirement is met, that is, the kneading effect is achieved or the kneading quality meets the standard, and the power range gradually decreases and tends to be stable, that is, it remains below the power range threshold.

[0053] In some embodiments, before obtaining the power extreme difference threshold, it also includes: obtaining the current temperature of the carbon paste; if the current temperature is within the preset temperature range, the kneading quality of the carbon paste meets the second preset requirement, and executing the step of obtaining the power extreme difference threshold; if the current temperature is not within the preset temperature range, adjusting the temperature of the carbon paste so that the temperature of the carbon paste is within the preset temperature range. The second preset requirement may be that the temperature of the carbon paste meets the standard. Before determining whether the current power extreme difference is less than or equal to the power extreme difference threshold, determine whether the current temperature is within the preset temperature range, and on the basis that the current temperature meets the standard, determine whether the current power extreme difference is less than or equal to the power extreme difference threshold.

[0054] In this way, the current temperature is within the preset temperature range, and the current power range is less than or equal to the power range threshold, indicating that the kneading quality of the carbon paste meets the first preset requirement. On the one hand, the kneading quality is determined by two factors, namely the temperature of the carbon paste and the power range of the stirring motor, thereby ensuring the accuracy of the kneading quality determination. On the other hand, the power range of the stirring motor replaces the kneading time, which is not affected by factors such as equipment and measurement, thereby improving the accuracy of the kneading quality determination, which is conducive to stabilizing the kneading quality, reducing the amount of unqualified green billets, saving energy consumption, and improving production efficiency.

[0055] In some embodiments, the kneading pot further includes a temperature detection module, and the temperature detection module is used to detect the temperature of the carbon paste. The obtaining of the current temperature of the carbon paste includes: detecting the temperature of the carbon paste by the temperature detection module to obtain the current temperature.

[0056] In some embodiments, the kneading pot also includes a heat medium heating device, and the heat medium heating device is used to heat the carbon paste. Before adjusting the temperature of the carbon paste so that the temperature of the carbon paste is within the preset temperature range, it also includes: detecting whether there are faults in the temperature detection module and the heat medium heating device; if so, repairing the temperature detection module and the heat medium heating device; if not, performing the step of adjusting the temperature of the carbon paste so that the temperature of the carbon paste is within the preset temperature range.

[0057] In some embodiments, regulating the temperature of the carbon paste so that the temperature of the carbon paste is within the preset temperature range includes: if the temperature of the carbon paste is greater than the upper limit of the preset temperature range, reducing the heat transferred by the heat medium through the heat medium heating device; if the temperature of the carbon paste is less than the lower limit of the preset temperature range, increasing the heat transferred by the heat medium through the heat medium heating device.

[0058] In some embodiments, the method further includes: if the current temperature is within the preset temperature range, returning to execute the step of obtaining the current temperature of the carbon paste, that is, continuously obtaining the current temperature.

[0059] In some embodiments, the kneading pot also includes a display screen, which includes a screen and a controller. The controller is electrically connected to the temperature detection module and the electrical detection module. The controller receives temperature data detected by the temperature detection module and current data and voltage data detected by the electrical detection module. The screen displays temperature data, current data, voltage data, power data, and power extreme difference data.

[0060] In some embodiments, the kneading pot further includes a control box, in which a power module is provided, and the power module is connected to the electrical detection module, the temperature detection module and the display screen to supply power to the electrical detection module, the temperature detection module and the display screen.

[0061] In some embodiments, the kneading pot further includes an audible and visual alarm light.

[0062] In some embodiments, the method further includes: if the current temperature is not within the preset temperature range, controlling the kneading pot to perform a first operation indicating that the kneading temperature does not meet the standard.

[0063] In some embodiments, controlling the kneading pot to perform the first operation indicating that the kneading temperature does not meet the standard includes: controlling the sound and light alarm light to flash, that is, the first operation is the sound and light alarm light flashing.

[0064] In some implementations, the further method includes: if the current power extreme difference is less than or equal to the power extreme difference threshold, controlling the kneading pot to perform a second operation indicating completion of kneading.

[0065] In some implementations, controlling the kneading pot to perform the second operation indicating completion of kneading includes: controlling the sound and light alarm light to be constantly on, that is, the second operation is that the sound and light alarm light is constantly on.

[0066] In some embodiments, it also includes: if the current power extreme difference is greater than the power extreme difference threshold, returning to execute the step of determining the current power extreme difference of the stirring motor within the cycle time.

[0067] In some embodiments, determining the current power range of the stirring motor within the cycle time includes: obtaining the maximum power and the minimum power of the stirring motor within the cycle time; and determining the current power range according to the difference between the maximum power and the minimum power.

[0068] In some embodiments, the kneading pot also includes an electrical detection module, which is used to detect the current and voltage of the stirring motor. The method of obtaining the maximum power and the minimum power of the stirring motor within a cycle time includes: within the cycle time, detecting the current and the voltage of the stirring motor in real time by the electrical detection module to obtain the real-time current and the real-time voltage; obtaining the real-time power according to the product of the real-time current and the real-time voltage; and taking the maximum value of the real-time power as the maximum power and the minimum value of the real-time power as the minimum power.

[0069] In some embodiments, steps S1 to S3 can be replaced by the following steps: obtaining a power change rate threshold; determining the current power extreme difference of the stirring motor within the cycle time; determining the current power change rate according to the quotient of the current power extreme difference and the cycle time; if the current power change rate is less than or equal to the power change rate threshold, the kneading quality of the carbon paste meets the first preset requirement. It can be understood that the determination of whether the power extreme difference is less than or equal to the power extreme difference threshold is replaced by the determination of whether the power change rate is less than or equal to the power change rate threshold.
