DETAILED DESCRIPTION

[0034] The drawings and the detailed description further describe the present application. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0035] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can be practiced without resorting to the other ways different from the description, therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0036] As shown in Figure 1 , the embodiment of the first aspect of the present application provides a sintering machine material distribution control method, the method comprises:

[0037] Step S110: acquiring first weight information when the target trolley passes under the bottom material distribution device of the upper horizontal track 121, second weight information when the target trolley passes under the material distributor 150 of the upper horizontal track 121, and material layer thickness information, mixed material moisture information, and speed information of the target trolley;

[0038] Step S120: determining the mixed material weight information according to the first weight information and the second weight information;

[0039] Step S130: adjusting the working state of the material distributor 150, and / or the moisture adjusting device, and / or the target trolley according to the relationship between the mixed material weight information, the material layer thickness information, the mixed material moisture information, the speed information of the target trolley and the corresponding preset value.

[0040] As shown in Figure 3 and Figure 4 , the sintering machine comprises a rack 110, a trolley 170, a transmission system, a raw material supply device, an ignition device 160, a wind box device 180, etc., wherein the raw material supply device comprises a bottom material distribution device and a material distributor 150 arranged at intervals. Wherein the rack 110 is provided with a closed circulating track, the circulating track comprises a horizontal track and a curve, the horizontal track comprises an upper horizontal track 121 and a lower horizontal track 122, the curve comprises a head curve 123 and a tail curve 124, the head curve 123 and the tail curve 124 connect the upper horizontal track 121 and the lower horizontal track 122. The trolley 170 can run around the circulating track, the number of trolleys 170 can be multiple, and multiple trolleys 170 form a trolley train on the circulating track, which are close to each other and independent of each other.

[0041] As shown in Figure 3 and Figure 4As shown, the transmission system of the sintering machine includes a driving device 130, a suspension system, a head star wheel 140, a tail star wheel 190, etc. The driving device can be a motor, a reducer, etc. The head star wheel 140 rotates at a low speed, and the tooth plate of the head star wheel 140 pushes the trolley 170 to run from the lower horizontal track 122 to the upper horizontal track 121 through the head bend 123. The trolley 170 that is leveled on the upper horizontal track 121 contacts the trolley train and pushes the trolley train to move in the direction of the tail of the sintering machine. After the trolley 170 that is just leveled is laid with bottom material by the bottom material laying device, the material distributor 150 distributes the material, and the ignition device 160 ignites, the trolley 170 is subjected to the sintering by the air bellow device 180. When the trolley 170 reaches the second air bellow device 180 at the tail of the sintering machine, the sintering is completed, and the sintered ore is unloaded under the control of the tooth plate of the tail star wheel 190 and the tail bend 124 after the trolley 170 enters the tail bend 124. Once the sintering work is completed, the trolley 170 continues to run along the circulating track to move to the lower horizontal track 122. The teeth of the tail star wheel 190 generally hang a plurality of trolleys 170, such as four trolleys 170, and part of the trolleys 170 have sintered ore, and the total weight will generate a relatively large torque on the center of the star wheel. The torque is converted into a thrust and pushes the trolley 170 that is leveled through the tail bend 124, and the trolley 170 catches up with the next group of trolley trains and pushes the trolley train to move in the direction of the head of the sintering machine along the lower horizontal track 122. After the trolley 170 moves to the head of the sintering machine, the trolley 170 is operated to the upper horizontal track 121 under the action of the tooth plate of the head star wheel 140, and the whole presents a circulating running mode. That is, when the trolley 170 runs to the lower horizontal track 122, the trolley 170 is empty and can be understood as an empty car state. When the trolley 170 runs to the bottom material laying device below the upper horizontal track 121, the bottom material laying device lays the bottom material on the trolley 170. When the trolley 170 runs to the material distributor 150 below the upper horizontal track 121, the material distributor 150 distributes the mixed material on the trolley 170. Then, the trolley 170 is ignited by the ignition device 160, subjected to the sintering by the air bellow device 180, and the like, and the sintered ore is unloaded at the tail bend 124. When the trolley 170 runs to the lower horizontal track 122 again, the trolley 170 is empty and recovers to the empty car state, and the cycle is repeated. Specifically, as shown in FIG. 1, on the upper horizontal track 121, the running direction of the trolley 170 is indicated by the arrow X. Figure 3 As shown in FIG. 1, on the upper horizontal track 121, the running direction of the trolley 170 is indicated by the arrow X.

[0042] The underlayer laying device can include an underlayer laying hopper provided with a sector gate, the sector gate is opened and closed by a manual mechanism to control the amount of feeding to realize the control of the discharging speed, the underlayer laying hopper is a suspended chute type, and the sector gate is a lower underlayer thickness adjusting gate.

[0043] The distributor 150 can be a nine-roller distributor or other structure. When the distributor 150 is a nine-roller distributor, the nine-roller distributor is formed by nine parallel circular rollers arranged at intervals to form eight screening gaps that gradually increase from top to bottom, and the mixed material passes through each screening gap from top to bottom to realize the gradual reduction of the particle size of the mixed material from bottom to top on the trolley 170, that is, the particle size of the mixed material on the trolley 170 is reasonably segregated along the height direction of the material layer. The faster the speed of the distribution roller, the greater the segregation of the mixed material on the trolley 170, and vice versa. In order to prevent the mixed material from being compressed and compacted when falling, a material loosening rod device is provided, which is installed on the middle lower part of the material layer of the trolley 170 and is fixed on the rack 110 of the sintering machine by bolts.

[0044] The sintering machine further includes a mixed material layer, the distributor 150 is in communication with the mixed material bin, and the mixed material in the mixed material bin is supplied to the trolley 170 through the distributor 150. The mixed material bin contains a mixture of multiple materials. Specifically, the sintering machine further includes a moisture adjusting device, which can include a secondary mixer. The mixed material bin is in communication with the moisture adjusting device, and the moisture adjusting device makes the moisture of the mixed material suitable, further forms small balls, and makes the mixed material have good air permeability. Specifically, the mixed material is transported to the mixed material bin after being mixed to have suitable moisture by the moisture adjusting device, or the moisture adjusting device is used to supply water to the mixed material bin to make the moisture of the mixed material in the mixed material bin suitable.

[0045] The material layer thickness can be understood as the thickness of the material layer on the trolley 170 after being distributed by the distributor 150, which can be understood as the sum of the thicknesses of the underlayer and the mixed material, or the thickness of the mixed material. The moisture of the mixed material can be understood as the moisture content of the mixed material contained in the mixed material bin, and the speed of the trolley 170 represents the running speed of the trolley 170.

[0046] From Figure 5The line graph of the relationship between the mixture moisture content and the bulk specific gravity and the permeability of the mixture shows that the permeability of the material layer is related to the bulk specific gravity of the material and the moisture content of the mixture, wherein the bulk specific gravity of the material refers to the weight per unit volume of the material during the sintering process. The thickness of the material layer has a certain proportional relationship with the vertical combustion time, but the relationship between the two is not so simple. The thickness of the material layer is also an important factor affecting the permeability of the material layer. The thicker the material layer, the worse the corresponding permeability; the thinner the material layer, the better the corresponding permeability. Permeability is an important factor affecting the vertical combustion speed, so the thickness of the material layer and the vertical combustion time are not simply linearly related. Only the qualitative determination can be made. The thinner the material layer, the earlier the sintering endpoint under the premise of constant speed of the trolley 170; on the contrary, the thicker the material layer, the later the sintering endpoint under the premise of constant speed of the trolley 170. Therefore, the weight of the mixture, the thickness of the material layer, the moisture content of the mixture, and the speed of the trolley 170 will affect the sintering quality of the sintering machine.

[0047] In the production process of the sintering machine, the trolley 170 moves along the circulating track at a certain speed. Specifically, the bodies of the plurality of trolleys 170 are tightly connected and have the same speed, and the material on the trolley 170 is continuous and inseparable. The target trolley can be understood as any one of the plurality of trolleys 170, and the target trolley can be the first, middle, or last one of the plurality of trolleys 170.

[0048] The first weight information is the weight information of the target trolley when it passes under the bottom material laying device of the upper horizontal track 121. Since the target trolley passes under the bottom material laying device of the upper horizontal track 121, the bottom material laying device performs a bottom material laying operation on the trolley 170, so the first weight information can be the sum of the empty trolley weight and the bottom material weight of the trolley 170.

[0049] The second weight information is the weight information of the target trolley when it passes under the material distributor 150 of the upper horizontal track 121. Since the target trolley moves to under the material distributor 150 of the upper horizontal track 121, the material distributor 150 performs a mixture laying operation on the trolley 170, and the trolley 170 moves along the upper horizontal track 121 from the bottom material laying device to under the material distributor 150, so the second weight information can be the sum of the empty trolley weight, the bottom material weight, and the mixture weight of the trolley 170.

[0050] Therefore, according to the first weight information and the second weight information of the same trolley 170, the mixture weight information on the trolley 170 can be determined. For example, the first weight information is M1, the second weight information is M2, and M2-M1=M21. Then M21 is the mixture weight information on the trolley 170.

[0051] The sintering machine distribution control method provided by the embodiments of the present application can obtain the first weight information when the target trolley passes below the bottom material laying device of the upper horizontal track 121, and the second weight information when the target trolley passes below the distributor 150 of the upper horizontal track 121, so as to determine the mixed material weight information on the target trolley. The material layer thickness information on the target trolley, the speed information of the target trolley, and the mixed material moisture information in the mixed material bin are obtained, and the working state of the distributor 150, and / or the moisture adjusting device, and / or the target trolley is adjusted according to the relationship between the mixed material weight information, the material layer thickness information, the mixed material moisture information, the speed information of the target trolley and the corresponding preset values, such as the relationship between the mixed material weight information and the mixed material preset value, the relationship between the material layer thickness information and the material layer thickness preset value, the relationship between the mixed material moisture information and the mixed material moisture preset value, and the relationship between the speed information of the target trolley and the target trolley speed preset value, such as adjusting the discharging speed of the distributor 150, and / or the water supply speed of the moisture adjusting device, and / or adjusting the running speed of the target trolley, so as to obtain better material layer distribution, material layer thickness, air permeability and other indicators, so as to improve the sintering quality and ensure good sintering quality.

[0052] Among them, the material layer thickness information can be obtained by an industrial camera and the like, the mixed material moisture information can be obtained by a moisture meter, and the speed information of the target trolley can be obtained by a speed sensor. It can be understood that the material layer thickness information, the mixed material moisture information and the speed information of the target trolley can also be obtained by other means.

[0053] Among them, according to the relationship between the mixed material weight information, the material layer thickness information, the mixed material moisture information, the speed information of the target trolley and the corresponding preset values, one, two or three of the discharging speed of the distributor 150, the water supply speed of the moisture adjusting device and the running speed of the target trolley can be adjusted at the same time.

[0054] In some possible implementation embodiments provided by the present application, the first weight sensor and the second weight sensor are arranged on the upper horizontal track 121, the first weight sensor is arranged below the bottom material laying device, and the second weight sensor is arranged below the distributor 150. Among them, the first weight sensor and / or the second weight sensor can be mounted on the upper horizontal track 121, and can adopt a steel rail straight patch type or a plug-in type (shear type). Specifically, when the first weight sensor and / or the second weight sensor adopts the plug-in type, the first weight sensor and / or the second weight sensor can be embedded in the steel rail web plate or rail waist part of the upper horizontal track 121 to directly sense the steel rail shear stress. It can be understood that the first weight sensor and the second weight sensor can be connected to the sintering machine distribution control device 600 through a signal transmission line.

[0055] The step of acquiring the first weight information when the target trolley passes below the bottom material laying device of the upper horizontal track 121 and the second weight information when the target trolley passes below the material distributor 150 of the upper horizontal track 121 comprises:

[0056] The first weighing area is an area above the first weight sensor on the upper horizontal track 121. When it is determined that the target trolley runs to the first weighing area, the measurement value of the first weight sensor is acquired as the first weight information.

[0057] The second weighing area is an area above the second weight sensor on the upper horizontal track 121. When it is determined that the target trolley runs to the second weighing area, the measurement value of the second weight sensor is acquired as the second weight information.

[0058] In the embodiment, the first weighing area can be an area above the first weight sensor on the upper horizontal track 121. Since the first weight sensor is arranged on the upper horizontal track 121 and below the bottom material laying device, when it is determined that the target trolley runs to the first weighing area, it indicates that the target trolley runs to above the first weight sensor and the bottom material laying device has performed the bottom material laying operation on the target trolley. At this time, the measurement value of the first weight sensor is the sum of the empty trolley weight and the bottom material weight of the target trolley. Therefore, the measurement value of the first weight sensor is acquired at this time, and the measurement value of the first weight sensor can be taken as the first weight information, i.e., the first weight information is the sum of the empty trolley weight and the bottom material weight of the target trolley.

[0059] The second weighing area can be an area above the second weight sensor on the upper horizontal track 121. Since the second weight sensor is arranged on the upper horizontal track 121 and below the material distributor 150, when it is determined that the target trolley runs to the second weighing area, it indicates that the target trolley runs to above the second weight sensor and the material distributor 150 has performed the material distribution operation on the target trolley. At this time, the measurement value of the second weight sensor is the sum of the empty trolley weight, the bottom material weight and the mixed material weight of the target trolley. Therefore, the measurement value of the second weight sensor is acquired at this time, and the measurement value of the second weight sensor can be taken as the second weight information, i.e., the second weight information is the sum of the empty trolley weight, the bottom material weight and the mixed material weight of the target trolley.

[0060] Further, in the sintering machine production process, the trolley 170 moves along the circulating track at a certain speed, so the measurement of the weight of the trolley 170 is a dynamic measurement, such as the dynamic measurement of the weight of a train in motion. However, the measurement of the weight of the trolley 170 is different from the measurement of the weight of a train carriage, because the weight of a train carriage is a certain value and the carriage can be separated for measurement, while the plurality of trolley 170 bodies of the sintering machine are closely connected, and the material on the trolley 170 is continuous and cannot be divided, and the closely connected trolley 170 loads bulk materials between the upper horizontal track 121 and the lower horizontal track 122 of the sintering machine and circulates, so the measurement of the weight of the material on the trolley 170 is a combination of the two measurement methods of the weight of the material on the train (iron train) and the belt conveyor.

[0061] Therefore, the sintering machine material distribution control method provided by the embodiment of the present application sets weight sensors at different positions of the target trolley on the upper horizontal track 121, such as setting a first weight sensor at a position on the upper horizontal track 121 below the bottom material laying device and setting a second weight sensor at a position on the upper horizontal track 121 below the material distributor 150. When the target trolley runs to the first weighing area and the second weighing area, i.e., the target trolley passes above the first weight sensor and passes above the second weight sensor, the corresponding measurement is obtained as the first weight information and the second weight information, respectively, and the difference between the measurement values of the two weight sensors is used to determine the weight of the mixed material, which is beneficial to improve the accuracy of the measurement of the mixed material weight information and has a simple structure and convenient operation.

[0062] In some possible implemented embodiments provided by the present application, the identity is arranged on the axle of the target trolley, the first recognition positioning device is arranged at or near the position of the first weight sensor, and the second recognition positioning device is arranged at or near the position of the second weight sensor, and the method further includes:

[0063] Based on the recognition of the identity by the first recognition positioning device, it is determined that the target trolley runs to the first weighing area;

[0064] Based on the recognition of the identity by the second recognition positioning device, it is determined that the target trolley runs to the second weighing area.

[0065] In the embodiment, the axle of the target trolley is provided with an identity, the first identification positioning device is arranged at or near the position of the first weight sensor, the second identification positioning device is arranged at or near the position of the second weight sensor, when the first identification positioning device identifies the identity, it indicates that the axle of the target trolley runs to the first weighing area of the upper horizontal track 121, that is, the target trolley runs above the first weight sensor. When the second identification positioning device identifies the identity, it indicates that the axle of the target trolley runs to the second weighing area of the upper horizontal track 121, that is, the target trolley runs above the second weight sensor.

[0066] In the embodiment, the identity, the first identification positioning device and the second identification positioning device cooperate to identify whether the target trolley runs to the first weighing area and the second weighing area, which is beneficial to improve the accuracy of identifying and positioning the target trolley running to the first weighing area and the second weighing area, and has the advantages of simple structure and low cost.

[0067] The identity can be a two-dimensional code, an RFID (Radio Frequency Identification) card, etc. Specifically, the identity can be arranged at the position of the axle of the trolley 170 corresponding to the target trolley fence, and the identity can include target trolley number information, etc. For example, the identity includes the number "ABCD", wherein "A" represents the A number of the sintering machine, and "BCD" represents the number BCD of the trolley 170. For example, "5146" in the identity represents the trolley 170 with the number 146 of the No. 5 sintering machine. Specifically, when installing the identity, the identity is installed at the position opposite to the axle of the trolley 170 of the target trolley, which has a lower temperature and can better define and distinguish the position of the trolley 170 in the weight measurement. It can be understood that the identity can be arranged on each trolley 170 so that the axle of each trolley 170 has a corresponding identity.

[0068] The first identification positioning device and / or the second identification positioning device can be a two-dimensional code reading camera, an RFID card reader, etc. The first identification positioning device and / or the second identification positioning device are connected to the sintering machine material distribution control device 600 through a transmission line.

[0069] Specifically, the first identification positioning device is installed at or near the position of the first weight sensor, such as the side of the first sensor, to obtain the identity of the axle of the target trolley. It can be understood that when the first identification positioning device identifies the identity, it indicates that the axle of the target trolley runs to the first weighing area, that is, the target trolley runs above the first weight sensor.

[0070] Specifically, the second identification positioning device is installed at or near the position of the second weight sensor, such as being installed on the side of the second sensor to obtain the identity of the wheel axle of the target trolley. It can be understood that when the second identification positioning device identifies the identity, it indicates that the wheel axle of the target trolley runs to the position of the second weighing area, that is, the target trolley runs above the second weight sensor.

[0071] As shown in Figure 2 In some possible implementation embodiments provided in the present application, the sintering machine material distribution control method further comprises:

[0072] Step S210: obtaining third weight information when the target trolley moves to the lower horizontal track 122;

[0073] Step S220: determining the bottom material weight information according to the first weight information and the third weight information;

[0074] Step S230: adjusting the working state of the bottom material device according to the relationship between the bottom material weight information and the corresponding preset value.

[0075] In the embodiment, since the trolley 170 runs to the lower horizontal track 122, the trolley 170 has emptied the sintering material loaded on the trolley, which can be understood as an empty trolley state. By obtaining the third weight information when the target trolley moves to the lower horizontal track 122, that is, the third weight information is the empty trolley weight information of the target trolley, since the first weight information is the sum of the empty trolley weight and the bottom material weight of the target trolley, the bottom material weight information of the target trolley can be determined according to the first weight information and the third weight information, such as the third weight information M3, the first weight information M1, M1-M3=M13, and M13 is the bottom material weight information of the target trolley. Since the bottom material device performs the bottom material operation on the target trolley, the working state of the bottom material device can be adjusted according to the relationship between the bottom material weight information and the corresponding preset value, such as adjusting the discharging speed of the bottom material device according to the bottom material weight information and the bottom material weight preset value, adjusting the bottom material operation in the subsequent trolley 170, so that the bottom material weight information meets the requirement of the bottom material weight preset value, so as to obtain better bottom material index and improve the sintering quality.

[0076] In some possible implementation embodiments provided in the present application, the third weight sensor is arranged on the lower horizontal track 122. The third weight sensor can be installed on the lower horizontal track 122 and can adopt a steel rail straight patch type or a plug-in type (shear type). Specifically, when the third weight sensor adopts the plug-in type, the third weight sensor can be embedded in the steel rail web plate or rail waist part of the lower horizontal track 122 to directly sense the steel rail shear stress. It can be understood that the third weight sensor and the second weight sensor can be connected to the sintering machine material distribution control device 600 through a signal transmission line.

[0077] The step of obtaining the third weight information of the target trolley moving to the lower horizontal track 122 comprises:

[0078] The third weight sensor is determined to run to the third weighing area, and the measurement value of the third weight sensor is obtained as the third weight information.

[0079] In this embodiment, the third weighing area can be the area above the third weight sensor on the lower horizontal track 122. Since the third weight sensor is arranged on the lower horizontal track 122, when it is determined that the target trolley runs to the third weighing area, it means that the target trolley runs above the third weight sensor, and the target trolley has emptied the sintering material loaded on the trolley. At this time, the measurement value of the third weight sensor is the empty trolley weight of the target trolley. Therefore, at this time, the measurement value of the third weight sensor is obtained as the third weight information, that is, the third weight information is the empty trolley weight of the target trolley.

[0080] In this embodiment, when the target trolley runs to the third weighing area and the first weighing area, that is, the target trolley runs above the third weight sensor and above the first weight sensor, the corresponding measurement values are obtained as the third weight information and the first weight information, respectively. The difference between the measurement values of the two weight sensors is used to determine the weight of the bottom material, which is beneficial to improve the accuracy of the measurement of the weight of the bottom material, and the structure is simple and the operation is convenient.

[0081] In some possible implemented embodiments provided in the present application, an identity is arranged on the axle of the target trolley, and a third identification and positioning device is arranged at or near the position of the third weight sensor. The method further comprises:

[0082] Based on the third identification and positioning device identifying the identity, it is determined that the target trolley runs to the third weighing area.

[0083] In this embodiment, since the identity is arranged on the axle of the target trolley, and the third identification and positioning device is arranged at or near the position of the third weight sensor, during the running of the target trolley along the circulating track, when the third identification and positioning device identifies the identity, it means that the axle of the target trolley runs to the third weighing area of the lower horizontal track 122, that is, it is determined that the target trolley runs above the third weight sensor. Through the cooperation of the identity and the third identification and positioning device, whether the target trolley runs to the third weighing area is identified, which is beneficial to improve the accuracy of the identification and positioning of the target trolley running to the third weighing area, and the structure is simple and the cost is low.

[0084] The third identification and positioning device can be a two-dimensional code reading camera, an RFID card reader, etc. The third identification and positioning device is connected to the sintering machine material distribution control device 600 through a transmission line.

[0085] Specifically, the third identification positioning device is installed at or near the position of the third weight sensor, such as the side of the first sensor, to obtain the identity of the wheel shaft of the target trolley. It can be understood that when the third identification positioning device identifies the identity, it means that the wheel shaft of the target trolley runs to the position of the third weighing area, that is, the target trolley runs above the third weight sensor.

[0086] In some possible implementation embodiments provided in the present application, the step of adjusting the working state of the bedding material device according to the relationship between the bedding material weight information and the corresponding preset value comprises:

[0087] Based on the bedding material weight information being greater than the bedding material weight preset value, the discharging speed of the bedding material device is reduced;

[0088] Based on the bedding material weight information being less than the bedding material weight preset value, the discharging speed of the bedding material device is increased;

[0089] Based on the bedding material weight information meeting the bedding material weight preset value, the current discharging speed of the bedding material device is maintained.

[0090] In the embodiment, the discharging speed of the bedding material device affects the discharging amount of the bedding material, and further affects the weight of the bedding material. When the bedding material weight information is greater than the bedding material weight preset value, it means that the discharging amount of the bedding material is greater than the corresponding preset value. At this time, the discharging speed of the bedding material device can be reduced to reduce the discharging amount of the bedding material, so that the bedding material weight information of the trolley 170 behind the target trolley can meet the requirement of the bedding material weight preset value. When the bedding material weight information is less than the bedding material weight preset value, it means that the discharging amount of the bedding material is less than the corresponding preset value. At this time, the discharging speed of the bedding material device can be increased to increase the discharging amount of the bedding material, so that the bedding material weight information of the trolley 170 behind the target trolley can meet the requirement of the bedding material weight preset value. When the bedding material weight information meets the bedding material weight preset value, it means that the current discharging amount of the bedding material is reasonable, and the current discharging speed of the bedding material device can be maintained, so that the bedding material weight information of the trolley 170 behind the target trolley can continue to meet the requirement of the bedding material weight preset value.

[0091] Specifically, the bedding material device comprises a gate, and the discharging speed of the bedding material device can be reduced, increased or maintained by adjusting the opening degree of the gate.

[0092] In some possible implementation embodiments provided in the present application, the step of adjusting the working state of the material distributor 150, and / or the moisture adjusting device, and / or the target trolley according to the relationship between the mixed material weight information, the material layer thickness information, the mixed material moisture information, and the speed information of the target trolley and the corresponding preset value comprises:

[0093] The relationship between the mixture weight information, the layer thickness information, the mixture moisture information, the trolley 170 speed information and the corresponding preset values is taken as the input of the fuzzy control module, and the working state of the distributor 150, and / or the moisture adjusting device, and / or the target trolley is adjusted according to the output of the fuzzy control module.

[0094] In the embodiment, the relationship between the mixture weight information, the layer thickness information, the mixture moisture information, the trolley 170 speed information and the corresponding preset values is taken as the input of the fuzzy control module, and the working state of the distributor 150, and / or the moisture adjusting device, and / or the target trolley is adjusted according to the output of the fuzzy control module, so as to increase the control range, obtain better layer distribution, layer thickness, air permeability and other indexes, and improve the sintering quality and ensure good sintering quality.

[0095] Further, the adjustment of the working state of the distributor 150 includes reducing, increasing or maintaining the discharging speed of the distributor 150.

[0096] Further, the adjustment of the working state of the moisture adjusting device includes reducing, increasing or maintaining the water supply speed of the moisture adjusting device. For example, the moisture adjusting device includes an adjusting valve, and the opening degree of the adjusting valve is adjusted to reduce, increase or maintain the water supply speed of the moisture adjusting device.

[0097] Further, the adjustment of the working state of the target trolley includes reducing, increasing or maintaining the running speed of the target trolley. For example, the frequency converter of the target trolley is adjusted to reduce, increase or maintain the running speed of the target trolley.

[0098] The preset values corresponding to the mixture weight information, the layer thickness information, the mixture moisture information and the speed information of the target trolley can be set by the system.

[0099] In some possible implementation embodiments provided in the application, when the mixture weight information, the layer thickness information, the mixture moisture information and the speed information of the target trolley meet the corresponding preset value requirements, that is, the mixture weight information, the layer thickness information, the mixture moisture information and the speed information of the target trolley are all within the normal range set by the system, the discharging speed of the distributor 150, the water supply speed of the moisture adjusting device and the speed of the target trolley can remain unchanged.

[0100] When the mixture weight information deviates from the preset value of the mixture weight, the layer thickness information, the mixture moisture information, and the speed information of the target trolley meet the corresponding preset value requirements, the speed of the water supply device of the moisture adjusting device and the speed of the target trolley can be kept unchanged, and the discharging speed of the distributor 150 is adjusted until the mixture weight information meets the requirement of the preset value of the mixture weight. Specifically, when the mixture weight information is greater than the preset value of the mixture weight, the discharging speed of the distributor 150 can be reduced, and when the mixture weight information is less than the preset value of the mixture weight, the discharging speed of the distributor 150 can be increased.

[0101] When the mixture weight information deviates from the preset value of the mixture weight, the mixture moisture information deviates from the preset value of the mixture moisture, and the layer thickness information and the speed information of the target trolley meet the corresponding preset value requirements, the discharging speed of the distributor 150 and the speed of the target trolley can be kept unchanged, and the speed of the water supply device of the moisture adjusting device is adjusted until the mixture weight information meets the requirement of the preset value of the mixture weight and the mixture moisture information meets the requirement of the preset value of the mixture moisture. Specifically, when the mixture weight information is greater than the preset value of the mixture weight and the mixture moisture information is greater than the preset value of the mixture moisture, the speed of the water supply device of the moisture adjusting device can be reduced; when the mixture weight information is less than the preset value of the mixture weight and the mixture moisture information is less than the preset value of the mixture moisture, the speed of the water supply device of the moisture adjusting device can be increased.

[0102] When the mixture weight information deviates from the preset value of the mixture weight, the layer thickness information deviates from the preset value of the layer thickness, and the mixture moisture information meets the corresponding preset value requirements, the discharging speed of the distributor 150 and the speed of the water supply device of the moisture adjusting device can be kept unchanged, and the speed of the target trolley is adjusted until the mixture weight information meets the requirement of the preset value of the mixture weight and the layer thickness information meets the requirement of the preset value of the layer thickness. Specifically, when the mixture weight information is greater than the preset value of the mixture weight and the layer thickness information is greater than the preset value of the layer thickness, the speed of the target trolley can be increased; when the mixture weight information is less than the preset value of the mixture weight and the layer thickness information is less than the preset value of the layer thickness, the speed of the target trolley can be reduced.

[0103] It can be understood that the sintering machine layer measurement control can be realized by using fuzzy control reasoning or big data learning to form a knowledge base. For example, the relationship between the mixed material weight information, the layer thickness information, the mixed material moisture information, the target trolley information, and the corresponding preset values is taken as the input of the fuzzy control module, and the discharge speed of the distributor 150, and / or the water supply speed of the moisture adjusting device, and / or the running speed of the target trolley are adjusted according to the output of the fuzzy control module. The above-mentioned sintering machine distribution control method is only a part of the enumeration, and other embodiments are not enumerated one by one. It can be understood that, in general, it is preferred to consider adjusting the discharge speed of the distributor 150 and the water supply speed of the moisture adjusting device, and the running speed of the target trolley is not easily adjusted.

[0104] It can be understood that the sintering machine distribution control method provided by the embodiment of the present application can adjust the discharge speed of the distributor 150, and / or the water supply speed of the moisture adjusting device, and / or the running speed of the target trolley, and / or the discharge speed of the bottom material laying device according to the relationship between the mixed material weight information, the layer thickness information, the mixed material moisture information, the target trolley speed information, and the corresponding preset values.

In this way, according to the relationship between the mixed material weight, the bottom material weight, the layer thickness, the mixed material moisture, the target trolley speed, and the corresponding preset values, the actions of the distributor 150, the moisture adjusting device, the frequency converter of the target trolley, and the bottom material laying device are controlled to adjust the discharge speed of the distributor 150, and / or the water supply speed of the moisture adjusting device, and / or the running speed of the target trolley, and / or the discharge speed of the bottom material laying device, so as to obtain better layer distribution, layer thickness, layer permeability, and other indicators, and improve the sintering quality.
