Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention proposes a control method of a mixing apparatus, including:
step 11, acquiring index parameters of the mixing equipment when materials are mixed;
step 12, determining the current material state in the mixing bin of the mixing equipment according to the index parameters;
step 13, generating a control signal according to the material state in the mixing bin of the mixing equipment;
and 14, controlling the running state of the mixing equipment according to the control signal.
In this embodiment, the index parameter is generated during the process of mixing the materials in the mixing device, and is used to represent the state of the materials in the mixing device or the current operation state of the mixing device; the index parameters may include: the weight of materials in the mixing bin of the mixing device, the torque of the stirring shaft of the mixing device and the temperature in the mixing bin of the mixing device; the weight of the material can be monitored in real time through a preset weight sensor, and the torque of the stirring shaft can be reflected through the corresponding operating pressure of the driver when the driver drives the stirring shaft to rotate; here, the operating pressure corresponds to a driving pressure of hydraulic oil when the driver is hydraulically driven; of course, the driver is not limited to hydraulic driving, but can also be electric driving, and when the driver is electric driving, the torque of the stirring shaft can be represented by the corresponding running current of the driving motor when the driving motor drives the stirring shaft to rotate; preferably, in the actual operation process, the temperature can be monitored in real time through a preset pressure sensor or a preset current sensor on the driver, and the temperature can be monitored in real time through a preset temperature sensor;
in the process of mixing materials, the mixing equipment monitors and collects index parameters in real time through a preset sensor, generates corresponding control signals according to the material state in the mixing bin of the mixing equipment, and further realizes accurate control on the operation of the mixing equipment according to the control signals, so that the working efficiency of the mixing equipment is improved, and the equipment power consumption is reduced.
In an optional implementation of the present invention, when the index parameter is a weight of the material in the mixing bin and indicates that the material in the mixing bin is in an increased or decreased state, the step 13 may include:
step 131a, obtaining a first graph of the weight of materials in the mixing bin and the running time of mixing equipment;
in step 132a, a gate position control signal is generated according to the first graph and the preset weight value within the preset discharging time.
In this embodiment, when the index parameter is the weight of the material in the mixing bin monitored in real time, the weight of the material is taken as a dependent variable, the running time of the mixing device is taken as an independent variable, and a first graph of the weight of the material and the running time of the mixing device is drawn;
it should be appreciated that when the material weight indicates a decrease in material in the mixing chamber, the first plot may then characterize the material weight as inversely related to the mixing device run time; when the material weight indicates that the material in the mixing bin is increasing, the first graph can then characterize that the material weight is positively correlated with the mixing device operating time; the first graph represents a tendency of the mixing apparatus to increase or decrease in weight;
further, in a preset discharging time of the mixing equipment, generating a gate position control signal when the gate of the mixing equipment performs discharging according to the first graph and the preset weight value, so as to precisely control the gate height of the mixing equipment during discharging, and further assist in enhancing the movement of the mixed materials to a discharging area and improving the working efficiency of the mixing equipment;
the preset discharging time can be set according to the viscosity or actual requirements of the mixed materials; the preset weight value is the discharging amount set according to the actual requirement during discharging.

and step 141a, controlling the distance when the gate is opened during the discharging operation of the mixing equipment according to the gate position control signal.
According to the embodiment, according to the gate position control signal, the gate opening distance, namely the gate opening height, of the mixing equipment during discharging operation after mixing is controlled within the preset discharging time, so that the gate height of the mixing equipment during discharging can be accurately controlled, the gate height of the mixing equipment is ensured to be a certain distance below the level height of the mixed materials, and further, when the gate position control signal is generated and the gate is triggered to be opened, a large amount of materials cannot enter a discharging area in an uncontrolled manner due to strong material flowability, and the influence on subsequent procedures caused by accumulation of large materials in the discharging area is avoided;
it should be noted that when the gate of the mixing device does not receive the gate position control signal, the gate is in a closed state, but not in a completely closed state, so that the height of the mixed gate is ensured to be a certain distance above the level of the mixed material, and the gate is not required to be completely closed in place, thus ensuring that the gate can quickly respond after the gate position control signal is generated, and further improving the working efficiency of the mixing device.
In an implementation example of the present invention, when the gate of the mixing device receives the gate position control signal, when the actual discharging time of the mixing device exceeds the preset discharging time, it is proved that the viscosity of the mixed material is higher and the fluidity is poor, at this time, the gate can be controlled to be further opened, the height distance between the material and the material is increased, the distance difference is automatically adjusted according to the first graph of the weight reduction of the mixing device, that is, the weight reduction trend of the mixing device is smaller than the set value, the distance difference between the gate and the material level is increased, the movement of the waste material to the discharging area is assisted to be enhanced, and the working efficiency of the mixing device during discharging is improved.

further, judging whether the front-end crushing equipment finishes the work of conveying materials into the mixing equipment according to the change trend graph; when the change trend chart shows that the crushing equipment is still in crushing work, the mixing equipment is required to continuously receive new materials for feeding, mixing and compatibility, and a control signal for increasing the rotation speed of the stirring shaft can be generated according to the current continuous feeding state of the mixing equipment so as to improve the working efficiency of the mixing equipment; when the change trend graph shows that the crushing operation of the crushing equipment is finished and the second graph is gradually flattened, the feeding and mixing compatibility of the mixing equipment is finished, and a reduced stirring shaft rotating speed control signal is generated according to the current finishing state of the feeding and mixing compatibility of the mixing equipment so as to reduce the energy consumption of the mixing equipment;
further, in the process of discharging the material by opening the gate of the mixing device, when the fact that the actual discharging time of the gate exceeds the preset discharging time is monitored, the fact that the mixed material in the mixing bin is sticky at the moment is indicated, and an accelerating stirring shaft rotating speed control signal can be generated at the moment so as to improve the rotating speed of the stirring shaft, assist in enhancing the movement of the mixed material to the discharging area and improve the working efficiency of the mixing device.
In an optional implementation of the present invention, when the index parameter is a temperature in the mixing bin and indicates that the temperature in the mixing bin is in an increasing or decreasing state, the step 13 may include:
step 131c, obtaining a third graph of the temperature in the mixing bin and the running time of the mixing equipment;
