Description

Control method, device and equipment of feeding equipment and storage medium
Technical Field
The present invention relates to the field of conveying control, and in particular, to a method, an apparatus, a device, and a storage medium for controlling a feeding device.
Background
The multi-hearth furnace is a multi-hearth incinerator with a mechanical transmission device, also called a multi-layer furnace or a multi-stage furnace, and is widely applied to a plurality of industrial fields. Typically, the first half of the multi-hearth furnace is the drying zone for the material and the second half is the combustion zone for the material. The drying zone needs to ensure that the material cannot burn while removing the moisture from the material, and the combustion zone needs to ensure that the maximum allowable temperature of the multi-hearth furnace cannot be exceeded while fully burning the material. Thus, the feed to the multi-hearth furnace needs to be continuous and stable.
However, in practical applications, there may be a difference in the characteristics of each batch of material burned by the multi-hearth furnace, for example, the materials with different water contents may generate adhesion with different degrees. Thus, for different batches of material, if a fixed rate feed is used, the weight of the material delivered per unit time will likely be different, resulting in insufficient or excessive combustion of the material after it enters the multi-hearth furnace. Accordingly, there is a need for a feed control system that continuously and smoothly controls the feed to a multiple hearth furnace.
The prior art generally adopts two modes. The first way is to manually control the feed rate, which relies on the experience of the operator and adds significant labor costs. The second way is to improve the internal structure of the multi-hearth furnace to adjust the material conveying speed inside the multi-hearth furnace, which has the defects: on the one hand, the need to modify the multi-hearth furnace already in use adds additional costs, and on the other hand, it still has the same problems as the first way by artificially adjusting the speed.

According to a fourth aspect of the present disclosure there is provided a computer readable storage medium having stored thereon a computer program, characterized in that the computer program, when executed by a processor, is adapted to carry out the method according to the first aspect of the present disclosure.
According to one or more technical schemes provided by the embodiment of the disclosure, on one hand, since the feeding equipment is arranged outside the multi-hearth furnace and comprises the feeding part, the storage part and the conveying part, the conveying part conveys materials to the multi-hearth furnace, and the conveying speed of the conveying part can be controlled, so that the feeding of the multi-hearth furnace can be kept continuous and stable, the internal structure of the multi-hearth furnace which is put into use is not required to be modified, and the cost and the expenditure are saved. On the other hand, since the feeding part of the feeding device is used for supplementing materials to the storage part, the working state of the feeding part of the feeding device can be determined firstly, and when the feeding part is in a suspended working state, the average weight change value of the materials in the storage part in a first preset time period is determined; updating a first parameter according to the average weight change value; finally, controlling the transmission speed of the conveying part according to the target parameter and the first parameter; the first parameter is used for representing the material conveying capacity of the conveying part, and the target parameter is used for representing the material processing capacity of the multi-hearth furnace. Therefore, when the feeding part is in a suspended working state, the current material conveying capacity of the conveying part can be accurately judged through the average weight change of the materials in the storage part in the first preset time period. Moreover, according to the target parameter and the first parameter representing the material processing capacity of the multi-hearth furnace, the transmission speed of the conveying part is controlled, so that the problem caused by the need of manually controlling the transmission speed of the material in the related technology is solved, and a large amount of labor cost is saved.

The following description of the embodiments of the present disclosure will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present disclosure. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
Fig. 1 is a flowchart of a control method of a feeding device according to an exemplary embodiment of the present disclosure, as shown in fig. 1, including the following steps:
step S102: determining the working state of the feeding part, wherein the working state of the feeding part comprises a pause working state, a normal working state and/or a fault state;
in this embodiment, the feeding apparatus includes a feeding portion for replenishing the storage portion with the material, a storage portion for transporting the material in the storage portion to the hearth furnace, and a transporting portion. When the multi-hearth furnace works, the conveying part is always in a normal working state in order to ensure stable supply of materials.
Embodiments of the present disclosure are not limited to a particular type of material, for example, the material may be a filter cake, a mineral powder, or a sludge, among others.
The embodiment of the present disclosure is not limited to the specific structure of the feeding portion of the feeding apparatus, as long as the storage portion can be replenished with the material in some way. In this embodiment, the operating conditions of the feed portion include a suspended operating condition, a normal operating condition, and/or a fault condition. It will be appreciated that if the feeding portion is in the suspended state, it is indicated that the feeding portion is not currently replenishing the storage portion, and if the feeding portion is in the normal state, it is indicated that the feeding portion is currently replenishing the storage portion. No matter the feeding part is in a suspended working state or a normal working state, the feeding part is not in fault, and the feeding part can be controlled. If the feed section is in a fault condition, this means that the feed section cannot be controlled effectively. In one possible embodiment, the feed portion may include a switch. Normally, after the switch of the feeding part is opened, the feeding part should be in a normal working state. However, if the feeding portion is not replenished with material to the storage portion after the switch of the feeding portion is opened, it can be considered that the feeding portion is in a failure state. The cause of such a fault may be a fault in the switch itself or in the pre-arrangement for feeding material to the feed section. Alternatively, the feeding portion should be in a suspended state after the switch of the feeding portion is turned off, but if the feeding portion is still replenishing the storage portion with material after the switch of the feeding portion is turned off, the feeding portion may be considered to be in a failure state. It will be appreciated that the feed section may be considered to be in a faulty condition when at least one of the two conditions described above occurs.
The embodiments of the present disclosure are not limited to the specific structure of the storage section of the feeding apparatus. In one possible embodiment, the reservoir is a cylinder, for example a metering tank. The storage part can also be square, cuboid or other shapes, so long as the materials supplemented by the feeding part can be stored.
Embodiments of the present disclosure do not limit the specific capacity of the storage section of the feed apparatus. In a possible embodiment, the capacity of the storage section of the feed device is 30t (tons).
The embodiments of the present disclosure are not limited to the specific structure of the conveying section of the feeding apparatus, as long as the device or the component thereof can be changed in its conveying speed in some way. In one possible embodiment, the feeding device may employ a variable frequency screw as the conveying section, and the conveying speed of the variable frequency screw is controlled by changing the operating frequency of the variable frequency screw. Alternatively, the conveying of the variable-frequency screw is set to 8t/h (ton/hr), i.e., the maximum conveying speed of the variable-frequency screw is 8t/h.
The embodiments of the present disclosure are not limited to the specific manner of determining the operation state of the feeding portion described above. In a possible embodiment, as shown in fig. 2, determining the working state of the feeding portion includes:
Step S202, the state of the switch of the feeding part is obtained.
In embodiments of the present disclosure, the feed portion may include a switch. It will be appreciated that the switch is used to control the start or end of the replenishment process. In an ideal case, when the switch of the feeding part is opened, the feeding part should be in a normal working state; when the switch of the feeding part is closed, the feeding part should be in a suspended working state.
Embodiments of the present disclosure do not limit the timing of opening the switch of the feed portion. In one embodiment, when the weight of the material in the storage portion is lower than a preset weight threshold, the switch of the feeding portion is turned on; after the switch is turned on, the state of the feeding portion is set to an on state. It will be appreciated that the preset weight threshold is used to represent a lower limit for the material in the storage section. Alternatively, the preset weight threshold may be set based on the amount of material being processed by the multi-hearth furnace during a certain time interval in a normal state. For example, if the amount of material handled by the multi-hearth furnace in 2 hours in a normal state is 10t (ton), the preset weight threshold may be set to 10t. The advantage of this arrangement is that even if the switch of the feeding portion fails, the remaining material in the storage portion can be ensured to maintain the normal operation of the multi-hearth furnace for a certain period of time.
The specific manner in which the weight of the material in the above-described feeding apparatus is determined is not limited in this embodiment. In a possible embodiment, the feeding device further comprises a weighing section for determining the weight of the material in the storage section.
Optionally, when the weight of the material in the storage portion is lower than a preset weight threshold, the switch of the feeding portion is turned on, and specifically includes: when the weighing part detects that the weight of the material in the current storage part is lower than a preset weight threshold value, a first control signal is sent to the feeding equipment, and after the feeding equipment receives the first control signal, a switch of the feeding part is turned on to start material replenishment.
Optionally, when the weight of the material in the storage portion is lower than a preset weight threshold, the switch of the feeding portion is turned on, and specifically includes: when the weighing part detects that the weight of the material in the current storage part is lower than a preset weight threshold value, a first control signal is sent to the distributed control system, and after the distributed control system receives the first control signal, the feeding equipment is controlled to open a switch of the feeding part to start material replenishment.
The embodiments of the present disclosure do not limit the timing of closing the switch of the feeding portion. In one embodiment, when the volume of the material in the storage portion is greater than a preset volume threshold, the switch of the feeding portion is turned off; after the switch is turned off, the state of the feeding portion is set to the off state. It will be appreciated that the preset volume threshold is used to represent the upper limit of material in the reservoir. Alternatively, the preset volume threshold may be set based on the volume of the storage portion. For example, if the volume of the storage portion is 40 cubic meters, the preset volume threshold may be set to 37 cubic meters. Of course, a second weight threshold may also be provided for indicating an upper limit of the material in the storage section. However, the densities and properties of different types of materials are different, resulting in a high probability of a large difference in volume of the same weight of material. If a uniform upper weight limit is set for different types of materials, it is difficult to ensure that the volume of the storage part is not exceeded and the storage space of the storage part is utilized to the maximum in the process of replenishing the material to the storage part by the feeding part. Thus, the way of setting the preset volume threshold based on the volume of the storage section is better than the way of controlling the switch opening of the feeding section based on a certain upper weight limit, the advantage is that: in the process of supplementing the material to the storage part by the feeding part, the storage space of the storage part can be ensured to be maximally utilized without exceeding the volume of the storage part.
The disclosed embodiments do not limit the specific value of the feed rate of the feed section (i.e., the rate of supplemental material) so long as the feed rate is greater than the maximum conveying rate of the conveying section. The advantages of this arrangement are: even if the feeding device is in a state of 'feeding material while conveying the material to the multi-hearth furnace', the material amount of the storage part in the feeding device is increased, so that the normal operation of the multi-hearth furnace is ensured. In one possible embodiment, the maximum conveying speed of the conveying section is 8t/h. Alternatively, the feeding speed of the feeding portion may be much greater than the maximum conveying speed of the conveying portion, for example, the feeding speed of the feeding device described above is set to 45t/h, so that the time for replenishing the material can be greatly shortened.
The specific manner of determining the volume of material in the above-described feeding device is not limited in this embodiment. In a possible embodiment, the storage part further comprises a level switch. Optionally, a level switch may be provided at the top of the storage section for determining whether the volume of material in the current storage section is above a preset volume threshold. Alternatively, the level switch may be a tuning fork switch, or another type of level switch such as a capacitive level switch.
Optionally, when the volume of the material in the storage portion is greater than a preset volume threshold, the switch of the feeding portion is turned off, and specifically includes: when the material level switch detects that the volume of the material in the current storage part is larger than a preset volume threshold value, a second control signal is sent to the feeding equipment, and the feeding equipment closes the feeding switch after receiving the second control signal, so that the material supplementing is stopped.
Optionally, when the volume of the material in the storage portion is greater than a preset volume threshold, the switch of the feeding portion is turned off, and specifically includes: when the material level switch detects that the volume of the material in the current storage part is larger than a preset volume threshold value, a second control signal is sent to the distributed control system, and after the distributed control system receives the second control signal, the feeding equipment is controlled to close the feeding switch, and the material supplementing is stopped.
The embodiment of the present disclosure is not limited to a specific manner of acquiring the state of the switch of the feeding portion described above. Alternatively, the status of the switch of the feeding section may be obtained by sending a request to the feeding device. Alternatively, the feeding device may be controlled by a distributed control system, and the state of the switch of the feeding portion may be acquired by sending a request to the distributed control system.
Step S204, if the switch of the feeding part is in a closed state, determining the working state of the feeding part as a suspension working state.
In another possible embodiment, as shown in fig. 3, determining the working state of the feeding portion includes:
step 302, acquiring the state of the switch of the feeding part.
The details of step 302 are the same as those of step 202 in the previous embodiment, and will not be repeated for the sake of brevity.
Step 304, if the switch to the feeding portion is in an on state, determining M weight change values of the material in the storage portion within a second preset period, where M is an integer greater than 1.
In the present embodiment, the feeding speed of the feeding portion is set to be greater than the conveying speed of the conveying portion. Since the feeding portion is used to replenish the storage portion with material, and the conveying portion is used to convey the material in the storage portion to the multi-hearth furnace, the weight of the material in the storage portion should be increased when the feeding portion is in a normal operation state.
In this embodiment, the specific method for determining the M weight change values of the material in the storage portion during the second preset period is not limited. In a specific embodiment, the determining M weight change values of the material in the storage portion within the second preset period of time may include:
Acquiring the weight of the material in the storage part at the continuous M+1 moments in the second preset time period;
determining M weight change values according to the weight of the materials in the storage part at the continuous M+1 moments; the weight change value of the mth moment is equal to the weight of the material in the mth moment storage part minus the weight of the material in the mth+1th moment storage part, M is a positive integer, and m=1, … and M;
step 306, judging whether the M weight change values meet preset conditions;
and 308, determining the working state of the feeding part as a normal working state when the M weight change values meet preset conditions.
The present embodiment is not limited to a specific method of determining whether the M weight change values satisfy the preset condition. Optionally, when the M weight change values satisfy a preset condition, determining the working state of the feeding portion as a normal working state may include: when the proportion of the negative numbers in the M weight change values is greater than or equal to a preset proportion threshold value, determining the working state of the feeding part as a normal working state; or when the number of the negative numbers in the M weight change values is greater than or equal to a preset number threshold, determining the working state of the feeding part as a normal working state.
Alternatively, the preset number threshold may be set to M. The above-mentioned preset number threshold may also be set to other positive integers close to M in order to prevent the influence of data fluctuations. For example, if M is 6, the preset number threshold may be set to any one of integers 3-5. Alternatively, the above-mentioned preset proportion threshold may be set to 100%. The above-mentioned preset number threshold may also be set to other percentages close to 100% in order to prevent the influence of data fluctuations. For example, the preset ratio threshold may be set to any one of 50% -90%.
It can be understood that, assuming that the mth weight change value is a negative number, it is explained that the weight of the material in the storage portion at the mth time is smaller than the weight of the material in the storage portion at the mth+1th time, that is, the weight of the material in the storage portion is increasing, so that the feeding portion can be accurately reflected to be in a normal working state, that is, the feeding portion is supplementing the material to the storage portion, by "the proportion of the negative number in the M weight change values is greater than or equal to the preset proportion threshold value" or "the number of the negative number in the M weight change values is greater than or equal to the preset number threshold value".
In a specific embodiment, after performing step 306, the method may further include: and when the M weight change values do not meet the preset conditions, determining the working state of the feeding part as a fault state.
Optionally, when the M weight change values do not meet a preset condition, determining the working state of the feeding portion as the fault state may include: when the proportion of the negative numbers in the M weight change values is smaller than a preset proportion threshold value, determining the working state of the feeding part as a fault state; or when the number of the negative numbers in the M weight change values is smaller than a preset number threshold value, determining the working state of the feeding part as a fault state.
The advantages of this embodiment are: considering that the feeding part of the feeding device may be in a fault state, whether the current feeding part is in a normal working state cannot be accurately judged only according to the fact that the switch of the feeding part is in an open state. Therefore, in this embodiment, when the switch of the feeding portion is detected to be in an on state, whether the M weight change values of the materials in the storage portion meet the preset conditions within the second preset period of time is further determined, so that whether the feeding portion is in a normal working state or in a failure state can be more accurately determined, and the transmission speed of the conveying portion is controlled in different manners.
Step S104: and when the feeding part is in a suspended working state, determining an average weight change value of the materials in the storage part within a first preset time period.
In this embodiment, if the feeder is in a suspended state, it is indicated that the feeder is not currently replenishing the storage section.
The embodiment of the disclosure is not limited to the specific manner of determining the average weight change value of the material in the storage portion in the first preset period. In a possible embodiment, the determining the average weight change value of the material in the storage portion during the first preset period specifically includes:
based on a preset sampling time interval, acquiring the weight of the material in the storage part at N continuous moments in the first preset time period, wherein N is an integer greater than 2;
determining N-1 weight change values according to the weight of the materials in the storage part at the continuous N moments; wherein the nth weight change value is equal to the weight of the material in the storage part at the nth moment minus the weight of the material at the (n+1) th moment, N is a positive integer, n=1, …, N-1;
and determining the average weight change value according to the N-1 weight change values.
In a specific embodiment, the first preset time period may be 60 minutes, the preset sampling interval may be 1 minute, and N may be 61. When the feeding part is in a suspended working state, acquiring the weight of the material in the storage part every 1 minute to obtain the weight of the material in the storage part at 61 continuous moments; determining 60 weight change values according to the weight of the materials in the 61 moment storage parts; the average value was calculated from the 60 weight change values, and the calculated average value was used as the average weight change value.
Step S106: updating the first parameter according to the average weight change value; wherein the first parameter is used for representing the material conveying capacity of the conveying part.
In an alternative embodiment, the first parameter is updated only in two cases. The first case is when the feeding device is first started up, the above-mentioned first parameter is updated to a preset value, which may also be considered as an initialization of the first parameter, or a first update of the first parameter. The preset value may be set to a value calculated based on a configuration parameter of the conveying section of the feeding apparatus, or may be a predicted value empirically derived by an engineer. And in the second case, the feeding part is in a suspended working state, and the first parameter is updated according to the average weight change value of the materials in the storage part in a first preset time period. If the feeding part is in a suspended working state, the fact that the feeding part does not supplement materials to the storage part at present is indicated, and the materials in the storage part are only conveyed to the multi-hearth furnace through the conveying part. In other words, if the feeding portion is in a suspended working state, the material in the storage portion is only discharged and not fed, and at this time, the material conveying capability of the conveying portion can be accurately determined through the weight change of the material in the storage portion.
Alternatively, the historical value of the first parameter may be cached, either locally at the feeding device or uploaded to a server or an upper control system. If, in order to save storage space, only the last updated first parameter may be cached.
The embodiments of the present disclosure are not limited to the specific meaning of the first parameter, as long as the material conveying capacity of the conveying section can be characterized. In a specific embodiment, the first parameter may be the material transport speed of the transport section, which may be in t/h (tons/hour). In this embodiment, updating the first parameter according to the average weight change value may include:
calculating an average weight change value per unit time according to the average weight change value;
calculating the weight change speed according to the average weight change value in unit time;
and updating the first parameter according to the weight change speed.
Step S108: controlling a transport speed of the transport unit based on the target parameter and the first parameter; wherein the target parameter is used for representing the material handling capacity of the multi-hearth furnace.
The embodiment of the present disclosure is not limited to the specific manner of controlling the transport speed of the transport section according to the target parameter and the first parameter. In one possible embodiment, as shown in fig. 4, the controlling the conveying speed of the conveying section according to the target parameter and the first parameter specifically includes:
Step S402, inputting the target parameter and the first parameter to a proportional-integral-derivative PID control module to obtain an output result;
step S404, determining the operating frequency of the conveying part according to the output result;
step S406, controlling the conveying speed of the conveying part according to the operating frequency of the conveying part.
In the related art, the first half section of the multi-hearth furnace is a drying area of materials, and the second half section is a combustion area of the materials. The drying zone needs to ensure that the material cannot burn while removing moisture from the material, and the combustion zone needs to ensure that the maximum allowable temperature of the multiple hearth furnace cannot be exceeded while fully burning the material. The inventors have thus found that it is important whether feed control is smooth and continuous during incineration of material in a multiple hearth furnace. The unstable feeding process is easy to break the heat balance in the multi-hearth furnace, so that the system is fluctuated, and on the contrary, the stable and continuous feeding process is ensured, so that the fluctuation of the system is more favorably controlled.
In this embodiment, when the feeding portion is in the suspended operation state, after updating the first parameter according to the average weight change value of the material in the storage portion in the first preset period, a PID (proportional integral derivative) control module is used to control the conveying speed of the conveying portion. Optionally, the target parameter and the first parameter are respectively used as a set value and a process measured value (namely, input parameters of a PID control module) to obtain an output result, and the working frequency of a conveying part of the feeding equipment is determined according to the output result; and controlling the conveying speed of the conveying part according to the operating frequency of the conveying part.
Alternatively, the output result of the PID may be the operation frequency of the conveying portion, or may be a parameter related to the operation frequency of the conveying portion. Therefore, the operation frequency of the conveying section can be determined based on the relationship between the parameter and the operation frequency of the conveying section, and the conveying speed of the conveying section can be controlled.
In a specific embodiment, the conveying part may be a variable frequency screw, the working frequency of the variable frequency screw is f, and the pole pair number of the motor of the variable frequency screw is p. The output result of the PID control module can be the rotating speed N of the variable-frequency screw rod, the output result of the PID control module is converted into the working frequency of the variable-frequency screw rod according to the formula N=60 f/p, and the variable-frequency screw rod is regulated according to the converted working frequency, so that the transmission speed of the variable-frequency screw rod is controlled.
Since PID regulation is a linear combination of proportion, integral and differential regulation rules, the PID regulator absorbs the advantages of quick response of proportion regulation, capability of eliminating static difference and predictability of differential regulation. Compared with PD regulation, PID regulation improves the steady-state precision of the system and realizes indifferent control. Compared with PI regulation, PID regulation has one zero point, and this makes it possible to improve dynamic performance and PID control has both static performance and dynamic performance. Therefore, the deviation between the feeding state parameter and the target parameter of the current feeding equipment is reduced through the PID control module, so that stable and continuous feeding in the incineration process of the multi-hearth furnace can be ensured, the heat balance in the multi-hearth furnace is ensured, and the fluctuation of a system is controlled more easily.
In a specific embodiment, the design throughput of the multi-hearth furnace, which may be the maximum material handling speed of the multi-hearth furnace in an ideal state, may be set as the target parameter. For example, the above target parameter may be set to 3t/h (ton/hr).
In a specific embodiment, if the feeding portion is in a suspended working state, the materials processed by the multi-hearth furnace in the first preset time period can be further metered. In an alternative embodiment, after the determining the average weight change value of the material in the storage portion during the first preset period, the method may further include:
determining the total weight change amount of the materials in the storage part in the first preset time period according to the average weight change value of the materials in the storage part in the first preset time period;
and determining the weight of the materials processed by the multi-hearth furnace in the first preset time period according to the total weight change amount of the materials in the storage part in the first preset time period.
In another alternative embodiment, after determining the average weight change value according to the N-1 weight change values, the method may further include:
Determining the total weight change amount of the materials in the storage part in the first preset time period according to the N-1 weight change values;
and determining the weight of the materials processed by the multi-hearth furnace in the first preset time period according to the total weight change amount of the materials in the storage part in the first preset time period.
It will be appreciated that if the feeding portion is in a suspended state, indicating that the feeding portion is not supplying material to the storage portion, the material in the storage portion is only transported to the multi-hearth furnace by the transporting portion, and the amount of reduction of the material in the storage portion should be equal to the amount of material processed by the multi-hearth furnace during the same period of time. Therefore, the total weight change amount of the materials in the storage part in the first preset time period can be counted, the total weight of the materials processed by the multi-hearth furnace in the first preset time period can be accurately obtained, and the use party of the multi-hearth furnace can conveniently know the use working condition of the multi-hearth furnace in time.
In a specific embodiment, the feeding device may also be controlled when it is determined that the feeding portion is in a normal operating state. As shown in fig. 5, the method further includes:
step S502: when the feeding part is in a normal working state, acquiring a first parameter updated last time;
Step S504: and controlling the conveying speed of the conveying part according to the target parameter and the first parameter updated last time.
The specific manner of obtaining the first parameter updated last time is not limited in the embodiments of the present disclosure. It will be appreciated that the last updated first parameter value described above may be considered the last updated first parameter. In an alternative embodiment, the first parameter is updated only in two cases. The first case is when the feeding device is first started up, the above-mentioned first parameter is updated to a preset value, which may also be considered as an initialization of the first parameter, or a first update of the first parameter. The preset value may be calculated based on configuration parameters of the conveying section of the feeding apparatus, or may be set as a predicted value empirically derived by an engineer. And in the second case, the feeding part is in a suspended working state, and the first parameter is updated according to the average weight change value of the materials in the storage part in a first preset time period.
And if the feeding part is in a normal working state, indicating that the current feeding part supplements materials to the storage part. At the same time, the materials in the storage part are also conveyed into the multi-hearth furnace by the conveying part. It will be appreciated that the storage section is in a state of feeding and discharging simultaneously, in which case it is difficult to accurately determine the current material conveying capacity of the conveying section based only on the weight change of the material in the storage section. Under the premise, when the feeding part is in a normal working state, the value of the first parameter needs to refer to the last evaluation result of the material conveying capacity of the conveying part, namely, the last updated first parameter is obtained.
The embodiment of the disclosure is not limited to the specific manner of controlling the conveying speed of the conveying section according to the target parameter and the first parameter updated last time. In an optional embodiment, the controlling the conveying speed of the conveying section according to the target parameter and the first parameter updated last time specifically includes:
inputting the target parameter and the last updated first parameter to a proportional-integral-derivative PID control module to obtain an output result;
determining the operating frequency of the conveying part according to the output result;
and controlling the conveying speed of the conveying part according to the operating frequency of the conveying part.
Optionally, inputting the target parameter and the last updated first parameter to the PID control module to obtain an output result may include: and respectively taking the target parameter and the first parameter as a set value and a process measured value (namely the input parameter of the PID control module), and inputting the set value and the process measured value into the PID control module to obtain an output result.
Alternatively, the output result of the PID may be the operating frequency of the conveying portion, or may be a parameter related to the operating frequency of the conveying portion, and the operating frequency of the conveying portion may be determined according to the relationship between the parameter and the operating frequency of the conveying portion, so as to control the transmission speed of the conveying portion.
In a specific embodiment, the feeding device may also be controlled when it is determined that the feeding portion is in a faulty state. The method further comprises the following steps: when the feeding part is in a fault state, the transmission speed of the conveying part is adjusted to be a preset speed, and a warning signal is sent.
It will be appreciated that if the feed section is in a fault condition, this means that the feed section cannot be effectively controlled, and that the current material conveying capacity of the conveying section cannot be accurately determined. However, in order to ensure the normal operation of the multi-hearth furnace, the conveying part still needs to be kept in an operating state, and the conveying of the material to the multi-hearth furnace is continued, i.e., the conveying speed of the conveying part is adjusted to a preset speed. Meanwhile, an alarm signal is sent to prompt a worker to check and maintain.
The setting mode of the preset speed is not limited, and the preset speed is only required to be ensured to be smaller than the lowest transmission speed of the conveying part when the feeding part is in a normal working state. In an alternative embodiment, the preset speed = preset weight threshold/upper run time limit. The preset weight threshold is used for representing the lower limit of the materials in the storage part, and when the weight of the materials in the storage part is lower than the preset weight threshold, the switch of the feeding part is opened. The upper run time limit may be set by the multi-hearth furnace user to characterize the maximum time that multi-hearth furnace operation is expected when the feed section is in a fault condition. For example, the preset weight threshold may be set to 10t (ton), the upper run time limit to 2h (hour), the preset speed=the preset weight threshold/the upper run time limit=5 t/h (ton/hour).
According to the embodiment of the disclosure, on one hand, since the feeding equipment is arranged outside the multi-hearth furnace, the feeding equipment comprises the feeding part, the storage part and the conveying part, the conveying part conveys materials to the multi-hearth furnace, and the feeding of the multi-hearth furnace can be kept continuous and stable by controlling the conveying speed of the conveying part, so that the internal structure of the multi-hearth furnace which is put into use is not required to be modified, and the cost and the expenditure are saved. On the other hand, since the feeding part of the feeding device is used for supplementing materials to the storage part, the working state of the feeding part of the feeding device can be determined first, and when the feeding part is in a suspended working state, the average weight change value of the materials in the storage part in a first preset time period is determined; updating the first parameter according to the average weight change value; finally, controlling the transmission speed of the conveying part according to the target parameter and the first parameter; the first parameter is used for representing the material conveying capacity of the conveying part, and the target parameter is used for representing the material processing capacity of the multi-hearth furnace. Therefore, when the feeding part is in a suspended working state, the current material conveying capacity of the conveying part can be accurately judged through the average weight change of the materials in the storage part in the first preset time period. Moreover, according to the target parameter and the first parameter representing the material processing capacity of the multi-hearth furnace, the transmission speed of the conveying part is controlled, so that the problem caused by the need of manually controlling the transmission speed of the material in the related technology is solved, and a large amount of labor cost is saved.
