Description

Technical Field

[0001] This application relates to the field of belt scale deviation detection technology, and in particular, to a deviation detection method, apparatus, medium and equipment for a belt scale system. Background Technology

[0002] Electronic belt scales are key equipment in the sintering batching process. Their stability and accuracy play a crucial role in stabilizing the chemical composition of sintered ore and even directly affect the stability of blast furnace conditions. However, since electronic belt scales are dynamic weighing devices, their accuracy is affected by various factors in actual operation, such as the installation environment, belt tension variations, and sensor zero-point drift.

[0003] To detect the weighing error of electronic belt scales, we typically use periodic manual or chain-roller calibration methods. However, this calibration method requires stopping the feeding operation of the hopper and performing no-load calibration. This limitation prevents us from detecting abnormalities in the electronic belt scales online. Summary of the Invention

[0028] The technical solutions of the embodiments of this application are briefly described below:

[0029] According to some embodiments, such as Figure 1 , Figure 4 As shown, this application provides a deviation detection method for a belt scale system. The belt scale system includes a first belt scale 1, a second belt scale 2, a third belt scale 3, a fourth belt scale 4, and a mixing material belt scale 5. The first belt scale 1, the second belt scale 2, the third belt scale 3, and the fourth belt scale 4 are all disposed above the mixing material belt scale 5. The first belt scale 1, the second belt scale 2, the third belt scale 3, and the fourth belt scale 4 are used to feed material onto the mixing material belt scale 5. The detection method includes:

[0030] Step 101: Control the first belt scale 1, the second belt scale 2, the third belt scale 3 and the fourth belt scale 4 to feed the mixture onto the belt scale 5. After feeding reaches the set time t, the first actual feeding amount is obtained.

[0031] Step 102: Adjust the ratio of the first belt scale 1 and the second belt scale 2, or adjust the ratio of the third belt scale 3 and the fourth belt scale 4;

[0032] Step 103: Control the first belt scale 1, the second belt scale 2, the third belt scale 3 and the fourth belt scale 4 to feed the mixture onto the belt scale 5. After feeding reaches the set time t, the second actual feeding amount is obtained.

[0033] Step 104: Calculate the changed proportion based on the first actual feed amount and the second actual feed amount;

[0034] Step 105: One of the belt scales whose proportions are to be adjusted compensates for the change in proportions. The first belt scale 1, the second belt scale 2, the third belt scale 3 and the fourth belt scale 4 control the material to be fed into the mixed material belt scale 5. After the feeding reaches the set time t, the third actual feeding amount is obtained.

[0035] Step 106: Calculate the first feeding deviation of the belt scale to be compensated and adjusted based on the second actual feeding amount, the third actual feeding amount, and the changed proportion.

[0036] Based on the above embodiments, such as Figure 4 As shown, the upper end of the first belt scale 1 is equipped with a No. 1 mixing bin, the upper end of the second belt scale 2 is equipped with a No. 2 mixing bin, the upper end of the third belt scale 3 is equipped with a No. 3 self-produced return ore bin, and the upper end of the fourth belt scale 4 is equipped with a No. 4 blast furnace return ore bin.

[0037] First, control the first belt scale 1, the second belt scale 2, the third belt scale 3 and the fourth belt scale 4 to feed material onto the mixing belt scale 5. After feeding reaches the set time t, the material is weighed by the mixing belt scale 5 to obtain the first actual feeding amount.

[0038] Furthermore, the ratio of the first belt scale 1 and the second belt scale 2, or the ratio of the third belt scale 3 and the fourth belt scale 4, is adjusted. Specifically, the first belt scale 1 and the second belt scale 2 are interchanged, and the third belt scale 3 and the fourth belt scale 4 are interchanged. In some embodiments, the ratio of the first belt scale 1 is set to 37%, the ratio of the second belt scale 2 to 36%, the ratio of the third belt scale 3 to 15%, and the ratio of the fourth belt scale 4 to 12%. During the interchange, if the ratio of the first belt scale 1 is decreased by 15%, then the ratio of the second belt scale 2 is increased by 15%; if the ratio of the third belt scale 3 is decreased by 8%, then the ratio of the fourth belt scale 4 is increased by 8%. Secondly, the sum of the ratios of the first belt scale 1, the second belt scale 2, the third belt scale 3, and the fourth belt scale 4 is 100%. If the sum of the ratios of the first belt scale 1 and the second belt scale 2 is adjusted from 73% to 70%, then the sum of the ratios of the third belt scale 3 and the fourth belt scale 4 is adjusted from 27% to 30%.

[0039] Furthermore, after adjusting the proportions, the first belt scale 1, the second belt scale 2, the third belt scale 3, and the fourth belt scale 4 are controlled to feed material onto the mixing belt scale 5. After the feeding reaches the set time t, the material is weighed by the mixing belt scale 5 to obtain the second actual feeding amount.

[0040] Furthermore, the variation ratio is calculated based on the first and second actual feed amounts.

[0041] Furthermore, when adjusting the ratio of the first belt scale 1 and the second belt scale 2, the adjusted ratio is compensated for by adjusting the original ratio of the first belt scale 1, or by adjusting the original ratio of the second belt scale 2. The adjusted ratio on the first belt scale 1 is opposite to that on the second belt scale 2. Similarly, when adjusting the ratio of the third belt scale 3 and the fourth belt scale 4, the adjusted ratio is compensated for by adjusting the original ratio of the third belt scale 3, or by adjusting the original ratio of the fourth belt scale 4. The adjusted ratio on the third belt scale 3 is opposite to that on the fourth belt scale 4. Then, the first belt scale 1, the second belt scale 2, the third belt scale 3, and the fourth belt scale 4 are controlled to feed material into the mixing belt scale 5. After feeding reaches a set time t, the material is weighed by the mixing belt scale 5 to obtain the third actual feeding amount.

[0042] Furthermore, the first feeding deviation of the belt scale being compensated and adjusted is calculated based on the second actual feeding amount, the third actual feeding amount, and the changed proportion.

[0043] In some embodiments, the feeding deviations of other belt scales are calculated using a first feeding deviation calculation method. This enables online feeding deviation detection for the first belt scale 1, the second belt scale 2, the third belt scale 3, and the fourth belt scale 4.

[0044] To enable those skilled in the art to better understand this application, the following will be combined with Figure 1 The details of this application are described in detail.

[0045] According to some embodiments, in step 102, adjusting the ratio of the first belt scale 1 and the second belt scale 2, or adjusting the ratio of the third belt scale 3 and the fourth belt scale 4, the method includes:

[0046] The first original ratio of the first belt scale 1 is increased by a set ratio to obtain the first ratio, and the second original ratio of the second belt scale 2 is decreased by a set ratio to obtain the second ratio. The sum of the first original ratio and the second original ratio is equal to the sum of the first ratio and the second ratio.

[0047] Based on the above embodiments, the first belt scale 1 and the second belt scale 2 are interleaved, as are the third belt scale 3 and the fourth belt scale 4. In some embodiments, the proportion of the first belt scale 1 is set to 37%, the proportion of the second belt scale 2 to 36%, the proportion of the third belt scale 3 to 15%, and the proportion of the fourth belt scale 4 to 12%. During interleaving, if the proportion of the first belt scale 1 is decreased by 15%, then the proportion of the second belt scale 2 is increased by 15%; if the proportion of the third belt scale 3 is decreased by 8%, then the proportion of the fourth belt scale 4 is increased by 8%. Furthermore, the sum of the proportions of the first belt scale 1, the second belt scale 2, the third belt scale 3, and the fourth belt scale 4 is 100%. If the sum of the proportions of the first belt scale 1 and the second belt scale 2 is adjusted from 73% to 70%, then the sum of the proportions of the third belt scale 3 and the fourth belt scale 4 is adjusted from 27% to 30%.

[0048] Furthermore, this application will describe in detail an embodiment of adjusting the ratio of the first belt scale 1 and the second belt scale 2. A set ratio is added to the first original ratio of the first belt scale 1 to obtain the first ratio, and a set ratio is reduced to the second original ratio of the second belt scale 2 to obtain the second ratio.

[0049] According to some embodiments, in step 104, when calculating the changed proportion based on the first actual feed amount and the second actual feed amount, the method includes:

[0050] Subtract the first actual material feeding amount from the second actual material feeding amount to obtain the variable material feeding amount;

[0051] The changed proportions are calculated based on the changed feed rate.

[0052] Based on the above embodiments, the variable feed rate is calculated using the following formula:

[0053] ΔQ = Q2 - Q1;

[0054] Where ΔQ is the variable feed rate, Q2 is the second actual feed rate, and Q1 is the first actual feed rate.

[0055] The change ratio is calculated using the following formula:

[0056]

[0057] Where Δa is the variable ratio, L is the secondary batching material layer, v is the speed of the mixed material belt, and t is the set time.

[0058] According to some embodiments, a set ratio is added to the first original ratio of the first belt scale 1 to obtain a first ratio, and the set ratio is reduced to the second original ratio of the second belt scale 2 to obtain a second ratio. Then, in step 105, one of the belt scales whose ratio is being adjusted compensates for the change in ratio, controlling the first belt scale 1, the second belt scale 2, the third belt scale 3, and the fourth belt scale 4 to feed material onto the mixed material belt scale 5. After feeding reaches a set time t, a third actual feeding amount is obtained. The method includes:

[0059] Subtract the changed ratio from the first ratio of the first belt scale 1 to obtain the third ratio of the first belt scale 1;

[0060] After the first belt scale 1 is adjusted from the first ratio to the third ratio, the first belt scale 1, the second belt scale 2, the third belt scale 3 and the fourth belt scale 4 control the material to be fed into the mixed material belt scale 5. After the feeding reaches the set time t, the third actual feeding amount is obtained.

[0061] The variable ratio Δa can be positive or negative, depending on the relationship between the first and second actual feed amounts.

[0062] According to some embodiments, in step 106, when calculating the first feeding deviation of the compensated and adjusted belt scale based on the second actual feeding amount, the third actual feeding amount, and the changed proportion, the method includes:

[0063] The first actual change in material discharge amount of the first belt scale 1 is calculated based on the second actual discharge amount and the third actual discharge amount.

[0064] The first standard variable material feeding amount of the first belt scale 1 is calculated based on the changed ratio;

[0065] The first feeding deviation of the first belt scale 1 is calculated based on the first standard change in feeding amount and the first actual change in feeding amount.

[0066] Based on the above embodiments, the first actual change in material feed amount is calculated using the following formula:

[0067] q1 实 =Q3-Q2;

[0068] Where q1 实 Q1 represents the first actual change in feed rate, Q2 represents the third actual feed rate, and Q3 represents the second actual feed rate.

[0069] The first standard change in material feed amount is calculated using the following formula:

[0070] q1 标 = -Δa×L×v×t;

[0071] Where q1标 The first standard variable feed rate is L, the secondary batching material layer is v, the speed of the mixing belt is t, and the set time is t.

[0072] The first blanking deviation is calculated using the following formula:

[0073]

[0074] Where p1 is the first feeding deviation.

[0075] According to some embodiments, after calculating the first feeding deviation of the belt scale to be compensated and adjusted based on the second actual feeding amount, the third actual feeding amount, and the changed proportion in step 106, the method further includes:

[0076] The unit overflow ratio after the first belt scale 1 and the second belt scale 2 are inter-adjusted according to the changed material feed rate;

[0077] Subtract the unit overflow ratio from the first feeding deviation to obtain the second feeding deviation of the second belt scale 2.

[0078] Based on the above embodiments, the unit overflow ratio is calculated using the following formula:

[0079]

[0080] The second blanking deviation is calculated using the following formula:

[0081]

[0082]

[0083]

[0084]

[0085] p2 = p1 - Δa12.

[0086] According to some embodiments, the feeding deviation of the third belt scale 3 and the fourth belt scale 4 is calculated using the feeding deviation calculation method of the first belt scale 1 and the second belt scale 2.

[0087] The following describes an embodiment of the apparatus of this application, which can be used to perform the detection method in the above embodiments of this application.

[0088] Figure 2A simplified diagram of a deviation detection device 200 according to one embodiment of this application is shown. The belt scale system includes a first belt scale 1, a second belt scale 2, a third belt scale 3, a fourth belt scale 4, and a mixing belt scale 5. The first belt scale 1, the second belt scale 2, the third belt scale 3, and the fourth belt scale 4 are all disposed above the mixing belt scale 5. The first belt scale 1, the second belt scale 2, the third belt scale 3, and the fourth belt scale 4 are used to feed material onto the mixing belt scale 5. The deviation detection device 200 includes:

[0089] The first actual feed quantity module 201 is used to control the first belt scale 1, the second belt scale 2, the third belt scale 3 and the fourth belt scale 4 to feed the mixture to the belt scale 5. The first actual feed quantity is obtained after the feeding reaches the set time t.

[0090] The adjustment module 202 is used to adjust the ratio of the first belt scale 1 and the second belt scale 2, or to adjust the ratio of the third belt scale 3 and the fourth belt scale 4.

[0091] The second actual feed quantity module 203 is used to control the first belt scale 1, the second belt scale 2, the third belt scale 3 and the fourth belt scale 4 to feed the mixture to the belt scale 5. The second actual feed quantity is obtained after the feeding reaches the set time t.

[0092] The variable proportion module 204 is used to calculate the variable proportion based on the first actual feed amount and the second actual feed amount;

[0093] The third actual feed quantity module 205 is used to compensate for the change in the ratio of the adjusted ratio by one of the belt scales. It controls the first belt scale 1, the second belt scale 2, the third belt scale 3 and the fourth belt scale 4 to feed the mixture onto the belt scale 5. The third actual feed quantity is obtained after the feeding reaches the set time t.

[0094] The first feeding deviation module 206 is used to calculate the first feeding deviation of the belt scale being compensated and adjusted based on the second actual feeding amount, the third actual feeding amount, and the change ratio.

[0095] Based on the above embodiments, such as Figure 4 As shown, the upper end of the first belt scale 1 is equipped with a No. 1 mixing bin, the upper end of the second belt scale 2 is equipped with a No. 2 mixing bin, the upper end of the third belt scale 3 is equipped with a No. 3 self-produced return ore bin, and the upper end of the fourth belt scale 4 is equipped with a No. 4 blast furnace return ore bin.

[0096] First, control the first belt scale 1, the second belt scale 2, the third belt scale 3 and the fourth belt scale 4 to feed material onto the mixing belt scale 5. After feeding reaches the set time t, the material is weighed by the mixing belt scale 5 to obtain the first actual feeding amount.

[0097] Furthermore, the ratio of the first belt scale 1 and the second belt scale 2, or the ratio of the third belt scale 3 and the fourth belt scale 4, is adjusted. Specifically, the first belt scale 1 and the second belt scale 2 are interchanged, and the third belt scale 3 and the fourth belt scale 4 are interchanged. In some embodiments, the ratio of the first belt scale 1 is set to 37%, the ratio of the second belt scale 2 to 36%, the ratio of the third belt scale 3 to 15%, and the ratio of the fourth belt scale 4 to 12%. During the interchange, if the ratio of the first belt scale 1 is decreased by 15%, then the ratio of the second belt scale 2 is increased by 15%; if the ratio of the third belt scale 3 is decreased by 8%, then the ratio of the fourth belt scale 4 is increased by 8%. Secondly, the sum of the ratios of the first belt scale 1, the second belt scale 2, the third belt scale 3, and the fourth belt scale 4 is 100%. If the sum of the ratios of the first belt scale 1 and the second belt scale 2 is adjusted from 73% to 70%, then the sum of the ratios of the third belt scale 3 and the fourth belt scale 4 is adjusted from 27% to 30%.

[0098] Furthermore, after adjusting the proportions, the first belt scale 1, the second belt scale 2, the third belt scale 3, and the fourth belt scale 4 are controlled to feed material onto the mixing belt scale 5. After the feeding reaches the set time t, the material is weighed by the mixing belt scale 5 to obtain the second actual feeding amount.

[0099] Furthermore, the variable proportions are calculated based on the first and second actual feed amounts.

[0100] Furthermore, when adjusting the ratio of the first belt scale 1 and the second belt scale 2, the adjusted ratio is compensated for by adjusting the original ratio of the first belt scale 1, or by adjusting the original ratio of the second belt scale 2. The adjusted ratio on the first belt scale 1 is opposite to that on the second belt scale 2. Similarly, when adjusting the ratio of the third belt scale 3 and the fourth belt scale 4, the adjusted ratio is compensated for by adjusting the original ratio of the third belt scale 3, or by adjusting the original ratio of the fourth belt scale 4. The adjusted ratio on the third belt scale 3 is opposite to that on the fourth belt scale 4. Then, the first belt scale 1, the second belt scale 2, the third belt scale 3, and the fourth belt scale 4 are controlled to feed material into the mixing belt scale 5. After feeding reaches a set time t, the material is weighed by the mixing belt scale 5 to obtain the third actual feeding amount.

[0101] Furthermore, the first feeding deviation of the belt scale being compensated and adjusted is calculated based on the second actual feeding amount, the third actual feeding amount, and the changed proportion.

[0102] In some embodiments, the feeding deviations of other belt scales are calculated using a first feeding deviation calculation method. This enables online feeding deviation detection for the first belt scale 1, the second belt scale 2, the third belt scale 3, and the fourth belt scale 4.
