[0035] Exemplarily, the water flow rate in the water adding pipe may be detected to obtain the second water adding amount.

[0036] The water addition amount of the water addition pipe is controlled according to the first water addition amount and the second water addition amount.

[0037] Exemplarily, the first water addition amount and the second water addition amount may be compared to determine the water addition amount of the water addition pipe.

[0038] It should be noted that this embodiment determines the first water addition amount of the water adding pipe based on the feeding belt, and then controls the water addition amount of the water adding pipe in combination with the second water addition amount of the water adding pipe, thereby ensuring the accuracy of the water addition amount of the mixing system, and further ensuring the moisture stability of the mixed material output by the mixing system. The moisture content of the sintered mixture with stable moisture directly ensures the output, quality of the sintered ore and the stability of the sintering production.

[0039] In addition, this embodiment can realize front-end control of the amount of water added, avoid the lag in adjusting the amount of water added, and ensure the timeliness of the control of the amount of water added.

[0040] The moisture control method of the sintering mixture in this embodiment controls the water addition amount of the water adding pipe through the first water addition amount and the second water addition amount, thereby ensuring the accuracy of the water addition amount of the mixing system, and further ensuring the moisture stability of the mixture output by the mixing system.

[0041] In some embodiments, a method for controlling the moisture content of a sintered mixture is provided in an embodiment of the present application, and a first water addition amount of a water addition pipe is determined according to a material flow rate, comprising:

[0042] Step S201, establishing a coefficient determination model for a hybrid system;

[0044] Step S203, calculating the product of the material flow rate and the water addition coefficient to obtain a first water addition amount.

[0045] In this embodiment, a coefficient determination model for the mixing system is established, and the water addition coefficient corresponding to the material flow rate is determined through the coefficient determination model, wherein the water addition coefficient is a calculation coefficient of the water addition amount corresponding to the material flow rate, and the coefficient determination model is used to determine a machine learning model of the water addition coefficient.

[0048] Exemplarily, the calculation formula for the first water addition amount is:

[0049] G 目标 =K×Q n ;

[0050] Among them, G 目标 is the first water addition amount, K is the water addition coefficient, Q n is the material flow rate.

[0051] In some embodiments, a method for controlling the moisture content of a sintering mixture is provided in an embodiment of the present application, and a coefficient determination model of a mixing system is established, including:

[0052] Step S301, obtaining moisture data from a moisture detector and obtaining process parameters of a mixing system;

[0053] Step S302: Perform machine autonomous learning based on moisture data and process parameters to obtain a coefficient determination model.

[0054] In this embodiment, the mixing system further comprises a moisture detector, which is used to detect the water content of the mixture output by the mixer.

[0055] For example, the moisture detector can detect the water content of the sintering mixture produced by the mixer.

[0056] The moisture data of the moisture detector is obtained, and the process parameters corresponding to the mixing system are obtained, wherein the moisture data is the water content data of the mixture output by the mixer, and the process parameters are the relevant data of the mixing system during the production process.

[0057] For example, the process parameters may include parameters such as sintering material ratio, mixed material feed amount, mixed material particle size before mixing, and mixed material particle size after mixing.

[0058] Based on moisture data and process parameters, machine autonomous learning is performed to obtain a coefficient determination model.

[0059] Exemplarily, the current production material ratio is obtained and compared with the machine-self-learned material ratio to obtain the water addition coefficient of the current material ratio mixture and correct the original water addition coefficient. The corrected water addition coefficient participates in the moisture control of the mixer mixture.

[0060] In some embodiments, a method for controlling the moisture content of a sintering mixture is provided in an embodiment of the present application, and the water addition amount of a water addition pipe is controlled according to a first water addition amount and a second water addition amount, comprising:

[0061] Step S401, setting the water addition amount of the water addition pipe to a first water addition amount;

[0062] Step S402, calculating the difference between the first water addition amount and the second water addition amount to obtain a water addition adjustment amount;

[0063] Step S403, obtaining a preset water addition amount threshold;

[0064] Step S404, controlling the water addition amount of the water addition pipe according to the water addition amount threshold and the water addition adjustment amount.

[0065] In this embodiment, the difference between the first water addition amount and the second water addition amount is calculated to obtain the water addition adjustment amount, wherein the water addition adjustment amount is the difference between the first water addition amount and the second water addition amount.

[0066] Exemplarily, the calculation formula for the water addition adjustment amount is:

[0067] △G=G 目标 -G n ;

[0068] Among them, △G is the amount of water added, G 目标 is the first amount of water added, G n This is the second amount of water added.

[0069] A preset water addition amount threshold is obtained, and the water addition amount of the water addition pipe is controlled according to the water addition amount threshold and the water addition adjustment amount, wherein the water addition amount threshold is a preset threshold.

[0070] Exemplarily, the water addition amount of the water addition pipe is controlled by comparing the water addition amount threshold and the water addition adjustment amount.

[0071] In some embodiments, a method for controlling the moisture content of a sintering mixture is provided in an embodiment of the present application, and the water addition amount of a water addition pipe is controlled according to a water addition amount threshold and a water addition adjustment amount, including:

[0072] Step S501, under the condition that the water addition adjustment amount is less than or equal to the water addition amount threshold, the water addition amount of the water addition pipe is kept unchanged at the first water addition amount.

[0073] In this embodiment, under the condition that the water addition adjustment amount is less than or equal to the water addition amount threshold, it indicates that the first water addition amount does not need to be updated, and the water addition amount of the water addition pipe is kept unchanged at the first water addition amount.

[0074] Exemplarily, under the condition that the water addition adjustment amount is less than or equal to the water addition amount threshold, the first water addition amount is kept unchanged.

[0075] For example, △G is the water addition adjustment amount, A is the water addition threshold, when the secondary mixer water addition adjustment amount |△G|≤A, the secondary mixer target water addition amount G is maintained after △T time. 目标 unchanged, that is: G 目标 The water flow rate of the secondary mixer remains unchanged.

[0076] In some embodiments, a method for controlling the moisture content of a sintering mixture is provided in an embodiment of the present application, and the water addition amount of a water addition pipe is controlled according to a water addition amount threshold and a water addition adjustment amount, including:

[0077] Step S601, under the condition that the water addition adjustment amount is greater than the water addition amount threshold, data updating processing is performed on the first water addition amount to obtain an updated first water addition amount;

[0078] Step S602, setting the water addition amount of the water addition pipe to the updated first water addition amount.

[0079] In this embodiment, under the condition that the water addition adjustment amount is greater than the water addition amount threshold, data updating processing is performed on the first water addition amount to obtain an updated first water addition amount.

[0080] The water addition amount of the water addition pipe is set to the updated first water addition amount.

[0081] For example, △G is the water addition adjustment amount, A is the water addition threshold, when the mixer water addition adjustment amount |△G|>A, then after △T time, the mixer target water addition amount G 目标 Adjust, that is: Gn+1=G 目标 =K×Q n .

[0082] Exemplarily, the units of the first water addition amount and the second water addition amount are tons / hour.

[0083] In some embodiments, a method for controlling the moisture content of a sintering mixture is provided in an embodiment of the present application, and the method controls the amount of water added by a water adding pipe, comprising:

[0084] Step S701, controlling the amount of water added to the water adding pipe by adjusting the motor frequency of the water pump.

[0085] In this embodiment, the mixing system further comprises a water pump, which is arranged on the water supply pipe. By adjusting the motor frequency of the water pump, the amount of water added to the water supply pipe can be controlled.

[0086] For example, the ironmaking department of a steel company adopts a three-stage mixing process (one vertical mixing + two drum mixing + three drum mixing). Sintering metal materials, flux, fuel, blast furnace return ore, etc. are batched in the primary batching room according to the set ratio through a disc feeder and an electronic scale, and then transported to a primary vertical mixer by a belt to add water and mix, and then enter the secondary batching room mixing bin. The secondary batching room is equipped with a blast furnace return ore bin, a self-produced return ore bin and two mixing bins. The mixed material, blast furnace return ore, and self-produced return ore are batched in the secondary batching room according to the set ratio through a disc feeder and an electronic scale, and then transported to the secondary mixer by a belt to add water, mix, and granulate. The mixed material after the second mixing is transported to the tertiary mixer by a belt to add water and granulate. After the mixed and granulated mixture, sintered ore is produced after the processes of distribution, ignition, sintering, crushing, cooling, and granulation.

[0087] In this embodiment, the first mixing, second mixing and third mixing all use a belt scale installed on the mixer feeding belt, a moisture detector installed on the mixer feeding belt, and a flow meter installed on the mixer water adding pipe. The moisture control of the mixture of each mixer is controlled as a relatively independent unit, and the addition of water to the mixture is mainly carried out in the secondary mixer. Therefore, this embodiment selects the moisture control of the secondary mixer for illustration.

[0088] The secondary batching room has two mixing bins, one blast furnace return ore bin and one self-produced return ore bin. The mixed material, blast furnace return ore and self-produced return ore are batched for the second time according to the set ratio through a disc feeder and an electronic scale.

[0089] The mixed material after secondary batching is conveyed to the mixer feeding belt via a belt, and a belt scale is installed on the mixer feeding belt. The mixed material feeding belt conveys the mixed material to the mixer cylinder, and the mixed material after mixing and granulation in the secondary mixer falls onto the mixer feeding belt, and a moisture detector is installed on the mixer feeding belt. A water supply pipe is set inside the secondary mixer cylinder, and multiple water supply nozzles are installed on the water supply pipe. The other end of the water pipe is connected to the water tank through a frequency conversion water pump.

[0090] During the production process, the control system adjusts the amount of water added to the secondary mixer by adjusting the frequency of the motor connected to the water pump. The water level in the water tank is ensured to be within a reasonable range through an automatic control system.

[0091] The belt scale on the mixer feeding belt can detect the real-time flow of the mixed material transported to the secondary mixer; the moisture detector on the secondary mixer feeding belt can detect the real-time moisture content of the mixed material after water is added and secondary mixing in the secondary mixer; the flow meter installed on the water adding pipe main can detect the real-time flow of water added to the secondary mixer.

[0092] The central controller collects data such as the flow rate (Q) of the belt scale on the secondary mixer feeding belt, the moisture content (M) of the moisture detector on the secondary mixer blanking belt, and the water addition amount (G) of the secondary mixer in real time, and performs data storage and calculation.

[0093] Parameters can be set in the central controller, including: secondary mixture water adding system K, secondary mixer water addition deviation A, time lag △T (i.e., the lag time of the secondary mixture from the belt scale to the secondary mixer inlet water adding point), etc.

[0094] like Figure 2 As shown in the figure, the control system collects the flow rate Q of the belt scale on the secondary mixer feeding belt at time Tn. n And the amount of water added to the secondary mixer G n , PLC (Programmable Logic Controller) central control system follows the program setting rules: G 目标 =K×Q n Calculate the real-time flow rate Q of the belt scale n Corresponding target water addition amount of secondary mixer (G 目标 ) and the secondary mixer water adjustment amount △G=G 目标 -G n .

[0095] When the water adjustment amount of the secondary mixer |△G|≤A, the target water addition amount G of the secondary mixer is kept unchanged after △T time, that is, keep G 目标 The water flow rate of the secondary mixer is unchanged; when the water adjustment amount of the mixer |△G|>A, the target water amount of the mixer G after △T time 目标 Make adjustments, namely: G n+1 =G 目标 =K×Q n .

[0096] When the water addition adjustment amount of the secondary mixer |△G|>A, the fuzzy controller is used to adjust the water addition amount. The fuzzy control principle is to use the Mamdani control rule to determine the fuzzy control rule, with the deviation e and the deviation change ec as the input, and u as the output system control value. The domain of the secondary mixture water addition deviation, the fuzzy language variable word set and the membership function are determined, and the control logic is formed through the PLC control language to realize the dynamic adjustment of the water addition amount.

[0097] When production is stable and the deviation between the actual water addition amount of the secondary mixture and the target water addition amount is within the allowable range, the current water meter moisture data, sintering material ratio, mixture feed amount, mixture particle size and other process parameters are collected, and the machine autonomous learning is used to generate the water addition coefficient of the mixture in the mixer that is suitable for different material ratios. The central control system intelligently obtains the current production material ratio and compares it with the machine autonomous learning material ratio to obtain the current material ratio mixture water addition coefficient (K) and corrects the original water addition coefficient. The corrected water addition coefficient K participates in the moisture control of the secondary mixer mixture.

[0109] Exemplarily, the first water addition amount may be a theoretical target water addition amount of the water addition pipe.
