Description

Technical Field

[0001] The present invention relates to the technical field of metallurgical refractory material treatment, and particularly relates to a fully automatic mixing operation system for resin-bonded carbon-containing refractory material mud. Background Art

[0002] Resin binders play a very important role in shaped refractories, and have a great influence on the kneading, forming properties of carbon-containing refractory material mud, as well as the microstructure and service performance of products. At present, the research on batching systems mainly focuses on feeding methods, mixing methods, types of binders, etc., with the aim of avoiding the generation of agglomerated material masses due to mud agglomeration or the problem of reduced labor productivity caused by too long kneading time of the mud, as well as the problem that the kneading of the resin viscosity fluctuation of carbon-containing refractory materials is not easy to control.

[0003] When the temperature in the muller is relatively low, the set temperature is often not reached when the mulling process is completed. If mulling continues, poor plasticity of the dry material may occur, or agglomerated false particles may easily occur after the current subsequently rises. At this time, when the mixing time meets the conditions, the current and time should be monitored. When the current does not exceed the normal value, the mulling time can reach a certain time to stop or discharge the material. Within the set mulling time, if the current exceeds the preset value, the machine can also be stopped or the material can be discharged in advance, which can effectively ensure the quality of the mud. For different environmental conditions, general technicians must formulate different kneading process plans in advance, and make corresponding judgments and controls on different batches of mud kneaded by the mixer by setting multiple process numbers, which not only increases the labor intensity, but also is not conducive to the overall control of mud quality and the expansion of production. Summary of the Invention

[0004] The purpose of the present invention is to provide a fully automatic mixing operation system for resin-bonded carbon-containing refractory material mud, and solve the following technical problems:

[0005] The present invention comprehensively considers various scheme models through initial temperature and humidity, mulling time, process temperature, and process current, and automatically selects the corresponding feeding program for mixing and feeding according to the current environmental temperature and humidity in different seasons, avoiding multiple manual interventions, and improving the quality control of mud and the level of automatic control.

[0044]

[0045]

[0046] Among them, there are two setting methods. One is to set from scratch, that is, first set the name of the program, and then set the parameters of each step of the program execution; the other is to modify on the basis of an existing program. Select an existing program and modify some parameters on the basis of the existing program according to the experimental requirements. In addition to the process program, parameters such as the set discharging target temperature, current upper limit, and automatic operation frequency are additionally set.

After modification, click the save button to enter the save interface; if you want to save as a custom setting, click the custom button, and then it can be saved. The save page will automatically close.

[0048] The manual module is equipped with a manual control interface. Enter the manual control interface through the manual button. If the device is running, an interface of "Please stop the device first!" will pop up. It is not possible to switch to the manual interface during the operation of the device. The instrument must be stopped first. Only when the device stops can it be manually operated; when on the manual page, the safety protection function set for the device does not work.

[0049] The module for online automatic optimization of parameters, through the accumulation of data, establishes a set of standard data models. According to the real-time environmental temperature and humidity, current and temperature inside the mixer, through real-time calculation of the PID algorithm, the output frequency of the mixer and the parameters of the mixing time are then optimized to achieve intelligent online optimization of the mixing process.

[0050] Operation Example 1:

[0051] In winter, spring or autumn, when the temperature T0 outside the mixer is lower than 15°C and the environmental humidity RH0 < 40%, Process 1 is used. After all steps are completed, if the temperature T1 inside the mixer is still less than the discharging set temperature T2, continue to run at the preset frequency Hz2 until T1 ≥ T2, and then execute the discharging program.

[0052] Operation Example 2:

[0053] In spring and autumn, when the temperature outside the mixer satisfies 15°C ≤ T0 ≤ 35°C and the environmental humidity RH0 < 40%, Process 2 is used. After all steps are completed, if the temperature T1 inside the mixer ≥ T2 (the discharging set temperature), the discharging program is normally executed.

[0054] Operation Example 3:

[0055] In summer when it is hot and humid, when the external temperature T0 of the mixer is > 35°C and the ambient humidity RH0 ≥ 40%, Process 3 is used. It is considered in two cases. The first is when the mixing process ends and the temperature T1 in the mixer ≥ the discharge set temperature T2, the discharge process is normally executed. The second case is when the temperature T1 in the mixer has already been greater than the discharge set temperature T2 before the mixing process is completed. At this time, the real-time operating current A1 of the mixer is judged. If A1 < A2, the mixer continues to run according to the program until the program is completed and discharged. If A1 ≥ A2, the discharge process is immediately executed.

Considering various scheme models comprehensively according to the starting temperature and humidity, mixing time, process temperature, and process current, and automatically selecting the corresponding feeding program for mixing and feeding according to the current ambient temperature and humidity in different seasons, avoiding multiple manual interventions, and improving the control quality of the mud and the level of automatic control.

[0057] The above has described in detail an embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
