[0029] To this end, the application provides a feeding control method, Figure 1 A step schematic diagram of the feeding control method provided by an embodiment of the application is shown in the figure. The method is applied to a sludge drying device. The sludge drying device transports materials to a hopper through a conveyor belt, and a crushing motor is arranged on one side in the hopper for crushing the materials. The sludge drying device further comprises a measuring sensor for detecting the water content of the materials and a weight sensor for detecting the weight of the materials. The sludge drying device can control the feeding of the materials by the feeding control method of the application, and the specific steps are as follows:

[0030] In step S110, first detection data corresponding to the measuring sensor and second detection data corresponding to the weight sensor are obtained.

[0031] In step S120, a target water content interval corresponding to the first detection data is determined based on preset interval endpoint values.

[0032] In step S130, a comparison result of the second detection data and a weight threshold value corresponding to the target water content interval is determined.

[0033] In step S140, an operating speed of the conveyor belt corresponding to the target water content interval and the comparison result is determined, and a first control signal is output to the conveyor belt.

[0034] In step S150, a working power of the crushing motor corresponding to the operating speed of the conveyor belt is determined, and a second control signal is output to the crushing motor.

[0035] It can be understood that the measuring sensor is a sensor for detecting the water content of the materials, and the first detection data provided by the measuring sensor is data corresponding to the water content of the materials. The weight sensor is used to detect the weight of the current feeding materials, and the second detection data provided by the weight sensor is data corresponding to the weight of the materials. It can be envisaged that the feeding control method of the application can be executed by a corresponding processor in the sludge drying device. Therefore, the processor can be connected to the measuring sensor and the weight sensor through multiple I / O pins on the processor to obtain the first detection data and the second detection data.

[0036] Corresponding to the moisture content of the material, a plurality of intervals are pre-set, and the device also records the interval endpoint values of each interval, so as to be compared with the specific value in the first detection data, and then determine the interval corresponding to the first detection data, that is, the target moisture content interval. In addition, for each interval set, it corresponds to a pre-set weight threshold value, which is used to compare the second detection data. It is conceivable that after determining the target moisture content interval to which the current first detection data belongs, the weight threshold value can also be determined accordingly, and then the current obtained second detection data is compared with the weight threshold value corresponding to the target moisture content interval, to determine whether the second detection data is greater than the weight threshold value.

[0037] After determining the comparison result, the device can determine the running speed of the conveying belt corresponding to the target moisture content interval and the comparison result of the second detection data, and then determine the working power of the crushing motor. It is conceivable that a corresponding control strategy is recorded in the device, and under the condition that the target moisture content interval and the comparison result of the second detection data are determined, the control strategy selected can be determined accordingly to control the conveying belt and the crushing motor.

[0038] For example, the device sets intervals A, B and C for the moisture content, and each interval is respectively provided with a corresponding weight threshold value. When it is determined that the target moisture content interval is interval A, the current detected second detection data is compared with the weight threshold value corresponding to interval A. If the second detection data is greater than the weight threshold value, the conveying belt is determined to run at a speed v a1 , and the crushing motor is determined to run at a power W a1 . It is conceivable that if the second detection data is less than or equal to the weight threshold value, the conveying belt is determined to run at a speed v a2 , and the crushing motor is determined to run at a power W a2 . Among them, the speed v a1 is greater than the speed v a2 , and the power W a1 is greater than the power W a2 .

[0039] It is conceivable that within the same moisture content interval, when the weight of the material is less than or equal to the weight threshold value corresponding to the interval, the conveying belt is controlled to run at a corresponding speed and the crushing motor is controlled to run at a corresponding power; and when the weight of the material is greater than the weight threshold value corresponding to the interval, the device controls the conveying belt to run at a higher speed and controls the crushing motor to run at a higher power. Therefore, the higher the speed of the conveying belt, the better the material carried thereon can fall into the crushing motor on one side of the hopper, which helps the crushing motor to better crush the material, so as to make the feeding of the sludge drying device uniform.

[0040] From the above scheme, the present scheme compares the detected data and values of the sludge drying equipment to determine the target moisture content interval to which the material belongs and the comparison result with the corresponding weight threshold, and further determines the state of the material, so as to further call the corresponding control strategy to make the conveying belt run at a corresponding running rate and the crushing motor run at a corresponding working power, thereby configuring different feeding modes for materials in different states to make the feeding of the sludge drying equipment more uniform, achieving control of the feeding, and without the need to add new processes, the equipment operation and maintenance difficulty is low, and the production cost can be effectively saved.

[0041] In some embodiments, for the result compared with the weight threshold, the device sets a corresponding parameter for identification. The target moisture content interval is the first moisture content interval or the second moisture content interval, and the device is provided with a first weight threshold corresponding to the first moisture content interval; the device is provided with a second weight threshold corresponding to the second moisture content interval. Accordingly, as shown in Figure 2 , Figure 2 The step of comparing the second detection data provided by an embodiment of the present application is shown in the following specific steps:

[0042] Step S210, if the target moisture content interval is the first moisture content interval, compare the second detection data with the first weight threshold to determine whether the second detection data is greater than the first weight threshold.

[0043] Step S220, the comparison result carries a first parameter corresponding to greater than the first weight threshold or a second parameter representing less than or equal to the first weight threshold.

[0044] It can be understood that after interval judgment of the first detection data, it is determined that the first detection data is located in the first moisture content interval, that is, in the case that the target moisture content interval is the first moisture content interval, the device compares the second detection data with the first weight threshold, and further carries the first parameter in the comparison result when the second detection data is greater than the first weight threshold; and carries the second parameter in the comparison result when the second detection data is less than or equal to the first weight threshold.

[0045] Similarly, after interval judgment of the first detection data, it is determined that the first detection data is located in the second moisture content interval, that is, in the case that the target moisture content interval is the second moisture content interval, the device compares the second detection data with the second weight threshold, and further carries the third parameter in the comparison result when the second detection data is greater than the second weight threshold; and carries the fourth parameter in the comparison result when the second detection data is less than or equal to the second weight threshold. Therefore, by setting a corresponding parameter to identify the comparison result, it is helpful for the device to better control the conveying belt and the crushing motor.

[0046] After determining the comparison result, the device determines the control of the running speed of the conveying belt according to the target moisture content interval and the comparison result. In an embodiment, when the target moisture content interval is the first moisture content interval, and the comparison result carries the first parameter, it is determined that the corresponding running speed of the conveying belt is the first speed, and the first speed is the current running speed.

[0047] When the target moisture content interval is also the first moisture content interval, and the comparison result carries the second parameter, it is determined that the corresponding running speed of the conveying belt is the second speed, and the second speed is the difference between the current running speed and the first change speed, that is, the second speed is less than the first speed.

[0048] In addition, when the target moisture content interval is the second moisture content interval, and the comparison result carries the third parameter, it is determined that the corresponding running speed of the conveying belt is the third speed, and the third speed is the sum of the current running speed and the second change speed, that is, the third speed is greater than the first speed.

[0049] When the target moisture content interval is also the second moisture content interval, and the comparison result carries the fourth parameter, it is determined that the corresponding running speed of the conveying belt is the fourth speed, and the fourth speed is the sum of the current running speed and the first change speed, that is, the fourth speed is greater than the first speed.

[0050] It is conceivable that after the device determines the running speed of the conveying belt, the device will send a first control signal to the conveying belt, so that the conveying belt receiving the first control signal can run at the corresponding running speed.

[0051] It should be noted that in some embodiments, the values of the moisture content in the first moisture content interval are all greater than the values of the moisture content in the second moisture content interval, and the first weight threshold is greater than the second weight threshold. It can be understood that under the same weight, the moisture content of the material is smaller, such as meeting the second moisture content interval, that is, the material is relatively dry compared with the material in the first moisture content interval, and thus it is more necessary to crush the material through the crushing motor, and accordingly, the running speed of the conveying belt is greater, and the material is more easily dropped into the crushing motor on one side of the hopper, and thus the material is crushed, so that the material can enter the sludge drying device more evenly.

[0052] In some embodiments, the second change speed is twice the first change speed, that is, in the second moisture content interval, the heavier the weight of the material, the higher the running speed of the conveying belt controlled by the device, and thus the material is better crushed.

[0053] In some embodiments, after determining the running speed of the conveyor belt, the device can determine the control strategy of the crushing motor accordingly. For example, in the case that the running speed is the first speed or the third speed, the device can determine that the working power of the crushing motor is the sum of the rated power and the first power value; in the case that the running speed is the second speed or the fourth speed, the device can determine that the working power of the crushing motor is the rated power. It is conceivable that the device will send a second control signal to the crushing motor, so that the crushing motor receiving the second control signal can operate at the corresponding power.

[0054] In some embodiments, the target moisture content interval can also be a third moisture content interval, wherein the values in the third moisture content interval are all greater than the values in the other intervals, i.e., in the third moisture content interval, the moisture content values thereon are all greater than the moisture content values in the other intervals. The device can be provided with three intervals corresponding to the moisture content, i.e., the first moisture content interval, the second moisture content interval and the third moisture content interval, and the values in the third moisture content interval are all greater than the values in the other intervals. Therefore, when the moisture content of the material is in the third moisture content interval, the device can determine that the moisture content of the material is too high, and then the device can output a third control signal for controlling the conveyor belt to run in reverse to the conveyor belt, so that the material with too high moisture content enters the sludge drying device and the device cannot complete the granulation.

[0055] For example, the device is provided with interval endpoint values 70 and 80, and correspondingly, the interval in which the moisture content of the material is greater than or equal to 70 and less than or equal to 80 is taken as the first moisture content interval, the interval in which the moisture content of the material is less than 70 is taken as the second moisture content interval, and the interval in which the moisture content of the material is greater than 80 is taken as the third moisture content interval.

[0056] When the current moisture content of the material is in the third moisture content interval, the device outputs a control signal for controlling the conveyor belt to run in reverse to the conveyor belt so that the conveyor belt can transport the material in reverse.

[0057] The device is provided with a first weight threshold value x corresponding to the first moisture content interval, and a second weight threshold value y corresponding to the second moisture content interval. When the current moisture content of the material is in the first moisture content interval, the device compares the second detection data with the first weight threshold value x, and if the second detection data is greater than the first weight threshold value x, the device determines the control strategy of the conveyor belt and the crushing motor accordingly. Specifically, the device can determine that the running speed of the conveyor belt corresponding thereto is the first speed V1=V a , and the working power of the crushing motor is W1=W+W0. If the second detection data is less than or equal to the first weight threshold value x, the device can determine that the running speed of the conveyor belt corresponding thereto is the second speed V2=V a -V a1 , and the working power of the crushing motor is W2=W.

[0058] When the current material moisture content is in the second moisture content interval, the device compares the second detection data with the second weight threshold value y. If the second detection data is greater than the second weight threshold value y, the device can determine that the corresponding running speed of the conveyor belt is the third speed V3=V a + 2*V a1 , and the working power of the crushing motor is W3=W+W0. If the second detection data is less than or equal to the second weight threshold value y, the device can determine that the corresponding running speed of the conveyor belt is the fourth speed V4=V a + V a1 , and the working power of the crushing motor is W4=W.

[0059] wherein V a is the current running speed of the conveyor belt, V a1 is the first change speed, W is the rated power of the crushing motor, and W0 is the first power value.

[0060] It is conceivable that after the device determines the control strategy for the conveyor belt and the crushing motor, the device sends corresponding control signals to the conveyor belt and the crushing motor respectively, so that the conveyor belt runs at the corresponding speed and the crushing motor runs at the corresponding power.
