[0069] S40, judging whether the real-time total tank stock amount is not less than the total tank upper limit threshold Totmax, wherein the total tank upper limit threshold Totmax is less than the tank stock second calculation threshold, the tank stock second calculation threshold is calculated based on all the single-bin upper limit thresholds Hmax, and the tank stock second calculation threshold is greater than the tank stock first calculation threshold; optionally, the tank stock first calculation threshold is obtained by summing all the single-bin upper limit thresholds Hmax;

[0070] S51, if the real-time total tank stock amount is not less than the total tank upper limit threshold Totmax, entering step S60

[0071] S52, if the real-time total tank stock amount is less than the total tank upper limit threshold Totmax, entering step S20;

[0072] Repeating steps S20 to S52 until the real-time total tank stock amount is not less than the total tank upper limit threshold Totmax, and entering step S60;

[0073] S60, feeding the stock bin i that does not meet the preset supply length under the current condition until all the stock bins meet the preset supply length, ending the current feeding cycle, and ending the raw material field feeding program.

[0074] The application provides a kind of automatic feeding control method of ingredient bunker, first, whether to trigger raw material yard feeding program is determined based on single bunker real-time material quantity or real-time total tank storage material quantity, and automatic response triggered feeding mode is realized;After determining that the raw material yard feeding program is triggered, the current lowest material level bunker i is determined as the target feeding bunker X, the feeding process of the target feeding bunker X is started, and the feeding timing window TX corresponding to the target feeding bunker X is established, and feeding based on the feeding timing window TX ensures the lowest feeding amount;After the target feeding bunker X is fed, the timing of the feeding timing window TX is started, and when the window length of the feeding timing window TX is reached and the material quantity of the target feeding bunker X reaches the single-bunker upper limit threshold Hmax, the feeding of the target feeding bunker X is completed, and whether to stop the feeding of a single bunker based on the two dimensions of the feeding timing window TX and the single-bunker upper limit threshold Hmax is beneficial to realize the maximum feeding of a single bunker at a time, and reduce the feeding switching frequency;Whether the real-time total tank storage material quantity is not less than the total tank storage upper limit threshold Totmax is judged, if the real-time total tank storage material quantity is not less than the total tank storage upper limit threshold Totmax, the bunker i that does not meet the preset supply time under the current condition is fed until all bunkers meet the preset supply time, the current feeding period ends, and the raw material yard feeding program ends, if the real-time total tank storage material quantity is less than the total tank storage upper limit threshold Totmax, the above steps are repeated until the real-time total tank storage material quantity is not less than the total tank storage upper limit threshold Totmax, after triggering the raw material yard feeding program, the current feeding time of each bunker after the current program feeding is further considered, and after the current feeding time reaches the preset supply time, the raw material yard feeding program ends. The method of the application realizes the automatic feeding of the ingredient bunker of the ingredient room, and reduces the mixing bunker feeding switching frequency and the ingredient room mixing ore feeding frequency.

[0075] Please refer to Figure 4 Understandably, in the sintering production process, the raw materials in the ingredient bunker are mostly from the raw material yard, especially the most used mixed ore, and the application scheme takes the single mixed ore provided by the raw material yard conveying as an example for illustration. In the prior art, multiple bunkers are designed in the ingredient room for buffering and ingredient of mixed ore, and the feeding of the mixed ore bunker is usually realized by manual operation. When the operator finds that the mixed ore bunker tank storage is low, the operator contacts the raw material yard for feeding, and when the mixed ore bunker reaches a certain position, the operator contacts the raw material yard to stop feeding. The inaccurate manual operation mode increases the feeding frequency, affects the working efficiency of the transportation system, increases the labor intensity of the operator, and increases the risk of material interruption of sintering ingredient.

[0076] Please refer to Figure 4It can be understood that the average feeding capacity of the raw material yard is Win tons per hour, and the value of the average feeding capacity is set with reference to the actual capacity of the stacker-reclaimer of the raw material yard. The average batching amount of the sintering production batching room is Wout tons per hour, wherein Wout < Win. The bin storage of the 1#, 2#, …, i#, …, n# mixed ore bins is detected and obtained through the weighing level meter, which is WL1, WL2, …, WLi, …, WLn tons respectively.

[0077] It can be understood that for the 1#, 2#, …, i#, …, n# mixed ore bins, the present application designs the working threshold value when the normal automatic feeding is designed: the single-bin upper limit threshold value Hmax and the single-bin lower limit threshold value Lmin, wherein when the position of a certain mixed ore bin reaches the single-bin upper limit threshold value Hmax, the feeding of the ore bin is stopped; when the position of a certain mixed ore bin is lower than the single-bin lower limit threshold value Lmin, the feeding of the ore bin is started.

[0078] Further, please refer to Figure 2 In another embodiment of the present application, step S60 specifically includes:

[0079] S61, determining the current lowest material level bin i as the decision feeding ore bin Y;

[0080] S62, judging whether the current feeding time of the decision feeding ore bin Y is greater than the preset supply time;

[0081] S63, if the current feeding time of the decision feeding ore bin Y is greater than the preset supply time, the current feeding cycle ends, and the raw material yard feeding program ends;

[0082] S64, if the current feeding time of the decision feeding ore bin Y is not greater than the preset supply time, supplement feeding is performed on the decision feeding ore bin Y until the current feeding time of the decision feeding ore bin Y is greater than the preset supply time or until the decision feeding ore bin Y reaches the single-bin upper limit threshold value Hmax;

[0083] Steps S61 to S64 are repeated until the current feeding time of the current lowest material level bin is greater than the preset supply time, the current feeding cycle ends, and the raw material yard feeding program ends.

[0084] In the scheme of the present application, the transport time of the mixed ore from the raw material yard to the sintering batching room is considered, and the transport time and the amount of material in the transport distance need to be considered when making the automatic control of the mixed ore bin feeding. The scheme of the present application innovatively adopts the total slot storage upper threshold Totmax of the 1st, 2nd, …, nth mixed ore bins, which is less than the total slot storage lower threshold Totmin. When ∑(WL1+WL2+…+WLn)>Totmax, the raw material yard feeding is stopped (the feeding process is gradually stopped from the source of the feeding process); when ∑(WL1+WL2+…+WLn)<Totmin, the mixed ore feeding of the raw material yard is started. The Totmin value can be set according to n*Lmin*K1, and the Totmax value can be set according to n*Hmax*K2. In addition, in order to reduce the feeding switching frequency of the 1st, 2nd, …, nth mixed ore bins, the feeding minimum time interval (preset time interval, feeding timing window TX) of the mixed ore bins is set, and when the feeding of a certain mixed ore bin is started, the feeding working time is not less than the preset time interval. In order to reduce the feeding frequency of the mixed ore bins in the batching room and prolong the time interval between two feedings, whether the slot storage of the low-level ore bin is less than T2, T2=WLY / Wout, is detected when the feeding is about to end each time, and when it is less than T2, the feeding of the ore bin is continued, otherwise the feeding is ended.
