[0002] CFB boilers have been widely used due to their wide fuel adaptability, high combustion and desulfurization efficiency, good load regulation performance, easy comprehensive utilization of ash and slag, high efficiency and low pollution. However, there are a large number of high-speed flowing high-temperature solid particles inside the CFB boiler, which cause serious scouring and wear on the boiler components, and the harsh environment of high temperature, high pressure and high corrosion inside the furnace further aggravates the wear and corrosion of boiler components. Reducing the impact of wear and corrosion on CFB boilers is conducive to reducing the frequency of boiler shutdown and maintenance and improving production efficiency. Wear-resistant refractory materials, as the key lining materials of CFB boilers, can effectively resist the scouring and wear of high-temperature solid particles and protect the integrity and stability of the boiler structure. In the preparation process of wear-resistant refractory castables, the traditional wear-resistant refractory material mixing process relies too much on manual judgment and lacks quantitative evaluation indicators, resulting in large differences in the uniformity of different batches of mixed materials, making it difficult for the quality of the cast finished product to reach the design limit. The mixing quality of wear-resistant refractory castables is directly related to the operating stability and safety of CFB boilers.

[0003] In the current relevant technologies, the mixing process control of wear-resistant refractory castables has technical problems such as low intelligence level, excessive reliance on manual judgment and experience, unstable mixing effect, and difficult to control fluctuations in finished product quality.

[0014] Preferably, the adaptive adjustment unit of the intelligent adaptive control subsystem divides the mixing process into four stages, including the initial mixing stage, the transition stage, the stabilization stage and the completion stage.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with specific implementation modes, but the protection scope of the present invention is not limited to the described contents.

[0019] Example 1: A rotary vibration wear-resistant refractory castable intelligent adaptive mixing system (see Figure 1 and Figure 2 ),include: A mixing subsystem, used for mixing the raw materials of wear-resistant and refractory castables to obtain finished castables; a vibration subsystem, vertically and dynamically connected to the mixing subsystem, for applying vibration disturbance to the mixing subsystem; An intelligent adaptive control subsystem is connected to the mixing subsystem and the vibration subsystem to realize intelligent adaptive control of the quality of the rotation and vibration process; The mixing subsystem includes a stirring tank 5, in which a stirring paddle 6 is inverted, and a pressure sensor 7 and a temperature sensor 4 are arranged on the stirring paddle 6, which are connected to the intelligent adaptive control subsystem in communication. A nonlinear stirring motor 10 is fixedly arranged at the lower end of the bottom plate of the stirring tank 5, and the output end of the nonlinear stirring motor 10 vertically passes through the bottom plate of the stirring tank 5 and is fixedly connected to the connecting end of the stirring paddle 6; the specific installation position and quantity of the pressure sensor 7 and the temperature sensor 4 can be adjusted in real time according to the construction requirements. Figure 2 Only one possible arrangement is shown. By increasing the number of sensors and staggering the arrangement of sensors, characteristic parameters of the mixing process at different planes in the mixing tank 5 can be extracted, thereby improving the adjustment accuracy of the intelligent adaptive control subsystem. Due to the uneven distribution of materials, the viscosity of materials in different areas and the heat released by hydrothermal reactions are different. During the mixing process, the pressure sensor 7 and the temperature sensor 4 rotate with the stirring paddle 6 in the stirring tank 5 to collect the pressure and temperature change characteristics at different radial distances and feed them back to the intelligent adaptive control system; like Figure 5 As shown, a discharge port is fixedly arranged at the bottom of the mixing tank 5, the bottom end of the discharge port is level with the bottom plate of the mixing tank 5, and a baffle plate that slides up and down is arranged at the top of the discharge port, and the discharge port is closed and opened by the baffle plate; The vibration subsystem comprises a vibration layer 3, a flexible connection layer 2 and a base layer 1 which are sequentially connected from top to bottom. The stirring tank 5 of the mixing subsystem is arranged at the top of the vibration layer 3. A through hole is opened at the center of the vibration layer 3. A nonlinear stirring motor 10 is arranged in the central through hole. A nonlinear vibration motor 9 is arranged outside the vibration layer 3. The diameter of the through hole is larger than the diameter of the nonlinear stirring motor 10 so that the vibration does not directly act on the nonlinear stirring motor 10. The three-layer structure of the vibration subsystem ensures the operation stability of the rotary vibration mixing system. The intelligent adaptive control subsystem comprises: The disturbance generation unit controls the nonlinear vibration motor 9 and the nonlinear stirring motor 10 based on the nested chaos principle, and applies precise rotation and vibration composite disturbance to the mixing process; The signal processing unit generates the mixing process stage modulus, performs feature analysis on the received mixing subsystem process monitoring signal, extracts the mixing stage parameters, and identifies the mixing process; The adaptive adjustment unit adaptively adjusts the peak value according to the mixing process signal fed back by the signal processing unit, so as to specifically enhance the mixing quality of raw materials; Specifically, the wear-resistant refractory castable raw material is added to the stirring tank 5 of the mixing subsystem. As the mixing proceeds, the stirring paddle 6 drives the pressure sensor 7 and the temperature sensor 4 to rotate in a circle in the wear-resistant refractory castable raw material. Due to the lack of uniformity of the mixed material in the early and middle stages of the mixing process, there is a phenomenon of raw material agglomeration, which causes obvious fluctuations in the reading of the pressure sensor 7. In addition, due to the hydrothermal reaction in the mixing process, there are differences in the heat released by the mixed material in different regions, which causes obvious fluctuations in the temperature data detected by the temperature sensor 4. In the later stage of the mixing process, the homogenization degree of the mixed material increases, and the fluctuation area of ​​the data detected by the pressure sensor 7 and the temperature sensor 4 is stable. The intelligent adaptive control subsystem collects the pressure and temperature change characteristics at different radial distances in real time, calculates the fluctuation characteristics as the mixing stage parameters, and automatically adjusts the peak value of the disturbance signal to achieve the optimal mixing strategy at different mixing stages. After the mixing is completed, according to actual needs, the worker can manually open the unloading baffle to discharge the finished mixed material. In the intelligent adaptive control subsystem, when the mixing operation starts, the disturbance generation unit generates a control signal through a nested chaotic formula to drive the nonlinear vibration motor 9 and the nonlinear stirring motor 10; at the same time, since the control signal is constantly changing, the duty cycle difference corresponding to the new and old control signals is calculated in real time, thereby adjusting the motor operation state and realizing accurate composite disturbance of rotation and vibration of the mixing process.

[0020] Embodiment 2: The rotary vibration type wear-resistant refractory castable intelligent adaptive mixing system of this embodiment is basically the same as the rotary vibration type wear-resistant refractory castable intelligent adaptive mixing system of embodiment 1, except that: like Figure 3 As shown, the upper surface of the vibration layer 3 of the vibration subsystem is fixedly provided with limiting devices 8 distributed in a circumferential array, the center of the limiting device 8 is located at the center point of the upper surface of the vibration layer 3, and the stirring tank 5 of the mixing subsystem is clamped on the vibration layer 3 of the vibration subsystem through the limiting device 8, so as to realize the rapid installation or separation of the vibration subsystem; the limiting devices 8 in a circumferential array on the surface of the vibration layer 3 ensure that the mixing subsystem is always placed in the center of the vibration layer 3 during the vibration process, and there is no risk of slipping; like Figure 4 As shown, the flexible connection layer 2 of the vibration subsystem is composed of a number of spring structures arranged in a circular array. The bottom end of the spring structure is fixedly set on the base layer, and the top end of the spring structure is vertically and dynamically connected to the vibration layer to facilitate the quick replacement of vibration layers with different needs. The reaction force of the vibration process is released by the shaking of the spring structure to maintain the stable operation of the intelligent adaptive mixing system. The number of spring structures is flexibly arranged according to the different needs of the mixing process, and the upper limit of the number of spring structures is only related to the bearing capacity of the arrangement space; the gravity of the mixing subsystem is used to apply a load to the vibration layer to maintain the stable connection between the vibration layer and the flexible connection layer in the working state; during the working process of the vibration layer 3, the spring structure arranged in a circular array in the flexible connection layer 2 shakes horizontally under the drag of the vibration layer 3, and the reaction force of the vibration is removed by the shaking of the spring structure, which can ensure that the base layer 1 is not affected by the vibration and that the vibration layer 3 does not overturn, thereby achieving stable operation of the mixing system.

[0021] Embodiment 3: The rotary vibration type wear-resistant refractory castable intelligent adaptive mixing system of this embodiment is basically the same as the rotary vibration type wear-resistant refractory castable intelligent adaptive mixing system of embodiment 2, except that: The disturbance generation unit of the intelligent adaptive control subsystem generates a nonlinear disturbance signal based on a nested chaotic attractor expression, and distributes it to the nonlinear stirring motor 10 and the nonlinear vibration motor 9 respectively. The nested nonlinear disturbance signal expression is: ; in, is the nonlinear disturbance signal, is the peak value of signal fluctuation, The value range of the chaos characteristic parameter is (0,1], is the state variable, i is the iteration time step; The signal processing unit of the intelligent adaptive control subsystem receives the fluctuation changes of the pressure and temperature signals of the mixing process transmitted by the mixing subsystem, draws the fluctuation curve, extracts the signal fluctuation characteristics, obtains the mixing stage parameters, and sends the mixing stage parameters to the intelligent adaptive control unit; the mixing stage parameter expression is: ; ; in, , are the pressure and temperature mixing stage parameters, is the iteration time step, and are the pressure and temperature state variables, and are the means of the pressure state variable and the temperature state variable, respectively.

[0022] The adaptive adjustment unit of the intelligent adaptive control subsystem divides the mixing process into four stages, including the initial mixing stage, the transition stage, the stabilization stage and the completion stage. After the mixing starts, due to the uneven mixing, the viscosity of the mixed materials in different areas and the heat released by the hydrothermal reaction of the mixed materials are different, the stage parameters and The fluctuations gradually become more intense, and this process is the mixing transition stage; as the mixing process proceeds, the uniformity of the mixture increases, and the stage parameters and The fluctuation of tends to be stable, and the mixture enters the stable stage; the stage parameters and After the preset time of relative stability, the adaptive control unit determines that the mixing has entered the completion stage. The stabilization time is selected according to the difference in the properties of the mixed raw materials and can be defined within the range of 5-60s. The signal peak value in the transition stage of the mixing is reduced to 80% of the signal peak value in the initial stage of the mixing, and the signal peak value in the stable stage of the mixing is reduced to 60% of the signal peak value in the initial stage of the mixing, so as to reduce the segregation effect of high-intensity vortex vibration disturbance on the mixture; By comparing and analyzing the mixing stage parameters fed back by the signal processing unit of the intelligent adaptive control subsystem with the process modulus of the mixing stage, the changes in the mixing stage are identified, and the adaptive control unit automatically completes the signal peak reduction; when the mixing completion stage parameter signal is identified, the mixing operation is terminated.
