DETAILED DESCRIPTION

[0043] The embodiment of the present application solves the technical problem in the prior art that it is difficult to accurately control the moisture content of mixed mineral powder by providing a method for controlling the moisture content of a mineral powder mixture.

[0044] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0045] An embodiment of the present application provides a method for controlling the moisture content of a mineral powder mixture. The method determines the moisture content of the mineral materials in each loading bin in the mineral powder mixture production system according to the moisture content of the mineral materials on the loading conveyor belt monitored by a first moisture detection device and the loading time. The method determines the target unloading amount corresponding to each loading bin according to a preset batching standard, and mixes the target unloading amount of each loading bin into a mixture to be detected, which is then conveyed to the batching conveyor belt. The moisture content of the mineral materials on the batching conveyor belt is obtained from a second moisture detection device. When the moisture content of the mineral materials in the mixture to be detected does not meet the preset moisture range corresponding to the preset batching standard, the loading bin with the highest moisture content among the loading bins is determined as the target loading bin, and the target unloading amount of the target loading bin is adjusted. It can be seen that the embodiment of the present application uses the first moisture detection device and the second moisture detection device to monitor the mineral powder moisture of the feeding conveyor belt and the batching conveyor belt respectively, and determines the mineral moisture in each feeding bin and the mineral moisture of the mixture to be tested. When the mineral moisture of the mixture to be tested does not meet the preset moisture range corresponding to the preset batching standard, the target discharge amount of the target feeding bin is adjusted in time, thereby achieving effective management of the mineral powder mixing process, accurately controlling the moisture content of the mixed mineral powder, improving production efficiency and product quality, and also optimizing the production process, reducing resource waste and increased energy consumption caused by improper moisture. In order to better understand the above technical scheme, the above technical scheme will be described in detail below in conjunction with the drawings in the specification and specific implementation methods.

[0046] First of all, the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0047] In the field of mineral processing, especially in pellet production, moisture control is a key factor to ensure the pelletizing performance, product quality and stable operation of the production line. Since water has a significant impact on the properties of minerals, the moisture content in the mixed mineral powder must be maintained within an appropriate range to ensure the yield and quality of raw pellets and optimize energy consumption. However, in actual large-scale industrial operations, due to the interference of factors such as the mineral processing process, material transportation conditions and external weather, maintaining the stability of the moisture content of the mineral powder has become a major challenge.

[0048] Although the existing technology has achieved real-time monitoring of the moisture content of the mixture by installing infrared or ultrasonic moisture detection devices on the conveyor belt, the single monitoring mechanism still lacks a subsequent effective active adjustment mechanism to cope with changes in the process flow. Especially in the application scenarios of large-scale equipment, conventional adjustment methods (such as adjustment based on experience) have great uncertainty and volatility and cannot accurately control the moisture content in the mixed mineral powder.

[0049] In order to solve the above problems, an embodiment of the present application provides a method for controlling the moisture content of a mineral powder mixture, which is matched with a mineral powder mixture production system.

[0050] First, the present application embodiment first describes the mineral powder mixture production system. Figure 1 As shown, the mineral powder mixture production system includes: a feeding conveyor belt 101, a batching conveyor belt 103, a mixing conveyor belt 102, a mixing device 3, a feeding bin 201, a first moisture detection device 401 and a second moisture detection device 402.

[0051] The mineral powder is transported from the top of each loading bin 201 to the bin for stacking and storage through the loading conveyor belt 101. A quantitative feeder 202 is set at the bottom of each loading bin 201. The quantitative feeder 202 can release a certain amount of mineral powder from the corresponding loading bin 201 to the mixing conveyor belt 102, which is then transported to the mixing device 3 for mixing. The mixed mineral material is released to the batching conveyor belt 103, and then transported to the next production process by the batching conveyor belt 103.

[0052] It should be noted that in Figure 1Five loading bins 201 and a quantitative feeder 202 corresponding to each loading bin 201 are shown. The structures of each loading bin 201 and the quantitative feeder 202 are consistent. In order to make the figure markings clear, only the first loading bin 201 and the fifth loading bin 201 are marked. Those skilled in the art can refer to the marked loading bins 201 for adaptive understanding of the three unmarked loading bins 201 in the middle.

[0053] During the mineral powder material transportation process, the first moisture detection device 401 detects the mineral material moisture of the material transported by the feeding conveyor belt 101, and the second moisture detection device 402 detects the mineral material moisture of the material transported by the batching conveyor belt 103. Exemplarily, the first moisture detection device 401 and the second moisture detection device 402 can detect the mineral material moisture of the material transported at their respective locations by infrared rays or sound waves.

[0054] Preferably, the ore powder mixed material production system further comprises: a weight reduction scale 502 and a dust ash storage bin 501. The weight reduction scale 502 can release a certain amount of dust ash from the dust ash storage bin 501 to the batching conveyor belt 103 to reduce the moisture content of the mixed ore.

[0055] The following describes a method for controlling the moisture content of a mineral powder mixture provided in an embodiment of the present application. Figure 2 As shown, the method includes steps S1 to S3.

[0056] Step S1, determining the corresponding mineral moisture in each loading bin 201 in the mineral powder mixture production system according to the mineral moisture of the loading conveyor belt 101 and the loading time monitored by the first moisture detection device 401;

[0057] Step S2, according to the preset batching standard, determine the target discharge amount corresponding to each loading bin 201, and mix the target discharge amount of each loading bin 201 into a mixed material to be tested, and convey it to the batching conveyor belt 103;

[0058] Step S3, obtaining the mineral moisture of the mixture to be tested on the batching conveyor belt 103 from the second moisture detection device 402. When the mineral moisture of the mixture to be tested does not meet the preset moisture range corresponding to the preset batching standard, the loading bin 201 with the highest mineral moisture among all the loading bins 201 is determined as the target loading bin, and the target unloading amount of the target loading bin is adjusted.

[0059] Regarding step S1, according to the mineral moisture of the feeding conveyor belt 101 and the feeding time monitored by the first moisture detection device 401, the corresponding mineral moisture in each feeding bin 201 in the mineral powder mixture production system is determined, including steps S11-S12.

[0060] Step S11, dividing each loading bin 201 into a plurality of loading sections along the height direction of each loading bin 201, and determining the moisture content of the mineral material corresponding to each loading section in each loading bin 201 according to the moisture content of the mineral material on the loading conveyor belt 101 monitored by the first moisture detection device 401 and the loading time corresponding to each loading section in each loading bin 201;

[0061] Step S12, determining the moisture content of the mineral materials in each loading bin 201 according to the moisture content of the mineral materials in each loading section in each loading bin 201.

[0062] The loading bin 201 is configured as a cube with uniform upper and lower volumes. In the process of conveying the mineral powder to the loading bin 201, the loading conveyor belt 101 uniformly conveys the mineral powder to the loading bin 201 for accumulation. Therefore, when the loading bin 201 is divided into a plurality of loading sections along the height direction, the mineral moisture content of each loading section in each loading bin 201 can be determined according to the loading time of each loading section and the mineral moisture content of the conveyed material monitored by the first moisture detection device 401 during this loading time, and then the mineral moisture content of each loading bin 201 can be determined.

[0063] For example, a loading bin 201 is divided into 10 loading sections from bottom to top, and the capacity of each loading section is equal. The first moisture detection device 401 monitors the moisture of the mineral material of the loading conveyor belt 101 once per second, and the moisture of the mineral material corresponding to the material conveyed per minute during the loading process can be obtained by the average value of the moisture of the mineral material detected by the first moisture detection device 401 within this minute, and the moisture of the mineral material corresponding to each loading section can be obtained by the average value of the moisture of the mineral material detected by the first moisture detection device 401 within this loading time.

[0064] That is, the above determination of the mineral moisture corresponding to each loading section in each loading bin 201 can be achieved by the following formula:

[0065]

[0066] Among them, W m is the mineral moisture corresponding to the material transported per minute, Ws is the mineral moisture detected by the first moisture detection device 401 per second, and W d is the moisture content of the ore corresponding to the feeding section, and t is the feeding time corresponding to the feeding section, usually in seconds.

[0067] Preferably, the moisture content of the mineral materials in each remaining loading section can be updated in real time according to the discharge amount of each loading bin 201 .

[0068] Regarding step S2, according to the preset batching standard, the target discharge amount corresponding to each loading bin 201 is determined, and the target discharge amount of each loading bin 201 is mixed into the mixed material to be tested, and conveyed to the batching conveyor belt 103. It includes steps S21 to S24.

[0069] Step S21, determining the pre-unloading amount of each loading bin 201 according to the preset batching standard;

[0070] Step S22, determining the moisture content of the premixed mineral material after the mineral materials are mixed according to the corresponding mineral material moisture content and the pre-feeding amount in each loading bin 201;

[0071] Step S23, when the moisture content of the premixed mineral material does not meet the preset moisture range, adjusting the pre-discharge amount of each loading bin 201;

[0072] Step S24 , when the moisture content of the premixed mineral material meets the preset moisture content range, the pre-discharging amount corresponding to each loading bin 201 is determined as the target discharging amount corresponding to each loading bin 201 .

[0073] Regarding step S21, the preset batching standard is set according to the production requirements of the mineral powder mixture, so as to determine the discharge amount of various mineral powders in each loading bin 201, that is, the pre-discharge amount.

[0074] Regarding step S22, the moisture content of the premixed mineral material after the mineral materials are mixed is determined according to the corresponding mineral material moisture content in each loading bin 201 and the pre-feeding amount. This can be achieved by the following formula:

[0075]

[0076] Where X is the number of feeding bins, X is a positive integer, W yu is the moisture content of premixed minerals, W n is the moisture content of the mineral material in the upper silo 201, N n It is the pre-loading amount of the loading bin 201.

[0077] For example, Figure 1 As shown, when five loading bins 201 are provided, the moisture content of the premixed mineral material is Wherein, W1-W5 are the moisture content of the mineral materials in the five loading bins 201 , and N1-N5 are the pre-unloading amounts of the five loading bins 201 .

[0078] It can be understood that the process of determining the moisture content of the premixed mineral material is an estimation process, that is, the moisture content of the premixed mineral material is an estimation value, not an actual value, and the moisture content of the mineral powder of the mixture to be tested after the mineral powder is mixed is detected by the second moisture detection device. Steps S21 to S24 are to reduce the possibility that the moisture content of the mineral powder of the mixture to be tested does not meet the preset moisture range.

[0079] Regarding step S23, when the moisture content of the premixed mineral material does not meet the preset moisture range, the pre-discharge amount of each loading bin 201 is adjusted.

[0080] It is understandable that the preset batching standards determined by different production requirements of mineral powder mixtures also have different requirements for the moisture content of the mixture, that is, there is a certain correspondence between the preset batching standards and the preset moisture range. For example, a certain pelletizing production process sets the preset moisture range of the mixture to 8.5% ± 0.5%.

[0081] Regarding step S24 , when the moisture content of the premixed mineral material meets the preset moisture content range, the pre-discharging amount corresponding to each loading bin 201 is determined as the target discharging amount corresponding to each loading bin 201 .

[0082] It should be noted that when the moisture content of the mineral material of the mixture to be tested does not meet the preset moisture range corresponding to the preset batching standard, in the process of adjusting the target discharge amount of the target loading bin, it is possible to return to execute steps S21-S24 to estimate the moisture content of the mineral material of the adjusted mixed mineral material.

[0083] Regarding step S3, the mineral material moisture of the mixture to be tested on the batching conveyor belt 103 is obtained from the second moisture detection device 402. When the mineral material moisture of the mixture to be tested does not meet the preset moisture range corresponding to the preset batching standard, the upper bin 201 with the highest mineral material moisture among the upper bins 201 is determined as the target upper bin, and the target unloading amount of the target upper bin is adjusted. In this way, the mineral material moisture content from the target upper bin in the mixture to be tested can be effectively adjusted, so that the moisture of the mixture to be tested is closer to the preset moisture range.

[0084] In the case where each loading bin 201 is divided into a plurality of loading sections along the height direction of each loading bin 201, the method further comprises:

[0085] When the moisture content of the mineral materials in the mixture to be tested does not meet the preset moisture range corresponding to the preset batching standard, the loading section at the bottom layer in each loading bin 201 is determined as the loading section to be compared, and the loading bin corresponding to the loading section to be compared with the highest mineral powder moisture content is determined as the target loading bin.

[0086] Since the loading bin 201 is configured as a top-in, bottom-out structure, the mineral material is released from the bottom of the loading bin 201 onto the mixing conveyor belt 102. By comparing the mineral powder moisture content of the loading sections at the bottom layer in each loading bin 201, and determining the loading bin 201 corresponding to the loading section with the highest mineral powder moisture content as the target loading bin, the process of adjusting the target discharge amount in step S3 to change the mineral powder moisture content of the mixed material to be tested can be made more effective.

[0087] Furthermore, since moisture may accumulate downward due to gravity, causing more moist mineral materials to accumulate at the bottom of the upper silo 201, a corresponding moisture detection device may be provided at the bottom of each upper silo 201 to monitor the moisture content of the mineral powder at the bottom of each upper silo 201, thereby making the adjustment process more accurate.

[0088] Regarding step S3, after adjusting the target unloading amount of the target loading bin, the method further includes:

[0089] Determine whether the moisture content of the mineral material of the mixture to be tested meets the preset moisture range corresponding to the preset batching standard. If not, re-determine the target loading bin.

[0090] It is understandable that after each adjustment of the target feed amount, the moisture content of the mineral powder in the bottom feeding section in the feeding bin 201 will change. Therefore, if the mineral material moisture content of the mixed material to be tested still does not meet the preset moisture content range, the target feeding bin needs to be re-determined. That is, the step of returning to the step of determining the bottom feeding section in each feeding bin 201 as the feeding section to be compared, and determining the feeding bin 201 corresponding to the feeding section to be compared with the highest mineral powder moisture content as the target feeding bin when the mineral material moisture content of the mixed material to be tested does not meet the preset moisture content range corresponding to the preset batching standard.

[0091] Regarding step S3, the mineral moisture of the mixture to be tested on the batching conveyor belt 103 is obtained from the second moisture detection device 402. When the mineral moisture of the mixture to be tested does not meet the preset moisture range corresponding to the preset batching standard, the loading bin 201 with the highest mineral moisture among all the loading bins 201 is determined as the target loading bin, and the target unloading amount of the target loading bin is adjusted.

[0092] In step S3, the target unloading amount of the target loading bin is adjusted, including:

[0093] According to the preset adjustment amount, the target discharge amount of the target loading bin is adjusted until the moisture content of the mineral powder in the mixture to be tested meets the preset moisture range.

[0094] In the case where the unloading time of each loading bin 201 is consistent, the preset adjustment amount can be reflected by the unloading rate of the target loading bin. For example, the preset adjustment amount is 50 tons / hour.

[0095] Furthermore, in the process of adjusting the target unloading amount of the target loading bin according to the preset adjustment amount until the moisture content of the mineral powder in the mixture to be tested meets the preset moisture range, the method also includes step S31-step S32.

[0096] Step S31, adjusting the target unloading amount of the target loading bin according to the preset adjustment amount, and accumulating the number of adjustments;

[0097] Step S32, when the adjustment times exceed the preset times and the mineral moisture of the mixture to be tested exceeds the preset moisture range, stop adjusting the target discharge amount of the target loading bin and add dust removal ash to the mixture to be tested until the mineral moisture of the mixture to be tested meets the preset moisture range.

[0098] Regarding step S31, the target unloading amount of the target loading bin is adjusted according to the preset adjustment amount, and the number of adjustments is accumulated.

[0099] It is understandable that the preset adjustment amount may change with the number of adjustments. For example, the preset adjustment amount corresponding to the first adjustment is 50 tons / hour, and the preset adjustment amount corresponding to the second adjustment is 40 tons / hour.

[0100] Regarding step S32, when the number of adjustments exceeds the preset number of times and the mineral moisture content of the mixture to be tested exceeds the preset moisture content range, stop adjusting the target discharge amount of the target loading bin and add dust removal ash to the mixture to be tested until the mineral moisture content of the mixture to be tested meets the preset moisture content range.

[0101] Exemplarily, when the moisture content of the mineral material in the mixture to be tested still exceeds the preset moisture range after the adjustment times exceed two times, the adjustment of the target discharge amount is stopped, and a certain amount of dust ash is released from the dust ash storage bin 501 to the mixture to be tested on the batching conveyor belt 103 through the reduction scale 502 until the moisture content of the mineral material in the mixture to be tested meets the preset moisture range.

[0102] In summary, the embodiment of the present application provides a method for controlling the moisture content of a mineral powder mixture. According to the moisture content of the mineral material on the loading conveyor belt 101 monitored by the first moisture detection device 401 and the loading time, the moisture content of the mineral material in each loading bin 201 in the mineral powder mixture production system is determined; according to the preset batching standard, the target discharge amount corresponding to each loading bin 201 is determined, and the target discharge amount of each loading bin 201 is mixed into a mixture to be detected, and conveyed to the batching conveyor belt 103; the moisture content of the mineral material of the mixture to be detected on the batching conveyor belt 103 is obtained from the second moisture detection device 402.
