Description

Technical Field

[0001] The present invention relates to the technical field of gypsum board production lines, and in particular to a coagulant batching adaptive control system and method. Background Art

[0002] During the high-speed production process of paper-faced gypsum board, the addition of accelerator ingredients can better promote the forming and bonding of the gypsum board.

[0003] The preparation rate of the coagulant is closely related to the demand for the coagulant by the gypsum board preparation system. If the preparation rate of the coagulant is slow and the preparation time is too long, the output of the coagulant is relatively low and cannot meet the demand for the coagulant by the gypsum board preparation system. If the preparation rate of the coagulant is fast and the preparation time is short, the output of the coagulant is greater than the demand for the coagulant by the gypsum board preparation system, and the redundant coagulant will be stored in the storage bin.

[0004] However, the storage conditions of gypsum board coagulants (usually sulfates or composite additives) need to be strictly controlled to ensure their chemical stability and effectiveness. When the produced coagulants are stored in a storage bin, in order to ensure the stability of the storage temperature and humidity, the coagulant preparation equipment needs to be frequently started and stopped to adapt to the demand for coagulants in the gypsum board preparation system and the maximum storage capacity of the storage bin. The production control system for coagulant ingredients in the existing technology does not take into account the control of coagulant output, which easily leads to the problem of frequent start-stopping of the coagulant preparation equipment and failure of the coagulant. Summary of the Invention

[0005] The purpose of the present invention is to provide an adaptive control system and method for coagulant ingredients to solve the technical problem that the existing technology does not take into account the control of coagulant production, which easily causes frequent start and stop of coagulant preparation equipment and coagulant failure.

[0006] In order to solve the above technical problems, the present invention specifically provides the following technical solutions:

[0007] A coagulant ingredient preparation system, comprising:

[0008] A raw material storage bin, a first conveying device, a coagulant preparation device, a second conveying device, and a finished product storage bin are sequentially arranged in a production sequence; the coagulant produced by the coagulant preparation device is transferred to the finished product storage bin via the second conveying device; and the coagulant in the finished product storage bin is transferred to the gypsum board preparation system via the unloading device below the finished product storage bin;

[0009] Wherein, the control units of the first conveying equipment, the coagulant preparation equipment, the second conveying equipment and the unloading equipment constitute a linkage control system;

[0010] The linkage control system calculates the output rate of the material feeding device and the material feeding amount per unit time of the material feeding device based on the unit addition amount of the coagulant required by the gypsum board preparation system;

[0011] The linkage control system controls the coagulant transport amount of the second conveying device per unit time to be the same as the coagulant transport amount of the coagulant preparation device per unit time based on the coagulant preparation amount per unit time, and determines the transport rate corresponding to the first conveying device;

[0012] The linkage control system establishes a matching relationship between the output rate of the unloading equipment, the transmission rate of the second conveying equipment, the preparation efficiency of the coagulant preparation equipment and the transmission rate of the first conveying equipment, so that when the output rate of the unloading equipment is adjusted, the transmission rate of the first conveying equipment can be automatically adjusted in linkage.

[0013] As a preferred solution of the present invention, the linkage control system includes: an early storage production management module, a mid-term balance production management module and a late discharge production management module;

[0014] The early stage storage production management module controls the coagulant preparation equipment to operate at the maximum preparation efficiency until the material level in the finished product storage bin reaches the maximum set value;

[0015] The mid-term balanced production management module regulates the production efficiency of the coagulant preparation equipment until the transmission volume of the second conveying equipment per unit time is equal to the discharge volume of the discharge equipment per minute, so that the material level in the finished product storage bin is constant at a maximum set value;

[0016] The post-discharging production management module calculates the time required to empty the finished product storage bin based on the volume of the finished product storage bin and the density of the stored coagulant, and determines the time point when the first conveying equipment stops transmitting in combination with the gypsum board preparation process.

[0017] As a preferred solution of the present invention, the switching between the early-stage material storage production management module and the mid-term balance production management module is triggered by a timer, wherein the specific time point at which the timer triggers the switching from the early-stage material storage production management module to the mid-term balance production management module is:

[0018] B*t=A*t+30%*R;

[0019] t = (30% * R) / (BA);

[0020] Wherein, B is the maximum delivery amount of the coagulant by the second delivery device per unit time, which is considered to be the same as the coagulant preparation amount of the coagulant preparation device per unit time;

[0021] A is the material discharge amount per minute corresponding to each output rate of the material discharge equipment;

[0022] R is the maximum storage capacity of the finished product storage bin;

[0023] t is the trigger time point for switching from the early material storage production management module to the mid-term balance production management module to switch the preparation rate of the coagulant preparation equipment and the transmission rate of the second conveying equipment.

[0024] As a preferred embodiment of the present invention, B=ɑ*B'; wherein B' is the raw material conveying amount of the first conveying device per unit time, ɑ is the preparation efficiency of the coagulant preparation device per unit time, ɑ is the ratio of the preparation discharge amount of the coagulant preparation device per unit time to the preparation input amount of the coagulant preparation device per unit time, and ɑ<1;

[0025] t=(30%*R) / (ɑ*B'-A).

[0026] As a preferred solution of the present invention, the mid-term balanced production management module controls B*t=A*t, and ɑ*B'=A, wherein B'=A / ɑ;

[0027] The raw material conveying amount of the first conveying device per unit time is A / ɑ, and the mid-term balanced production management module regulates the transmission rate of the first conveying device based on the raw material conveying amount of the first conveying device per unit time.

[0028] As a preferred solution of the present invention, the post-production management module determines the time point t3 = t2 - t1 for shutting down the first conveying device, the coagulant preparation device, and the second conveying device based on the time t1 required to empty the finished product storage bin and the production stop time t2 of the entire gypsum board preparation process;

[0029] The unloading equipment stops moving at the production stop point t2 of the entire gypsum board preparation process.

[0030] In addition, the present invention also provides an adaptive control method for a coagulant ingredient adaptive control system, comprising the following steps:

[0031] Step 100: Based on the gypsum board preparation process, determine the amount of coagulant added per unit time, and adjust the unloading amount of the finished product storage bin per unit time to be the same as the amount of coagulant added per unit time;

[0032] Step 200: monitor the material level in the finished product storage bin in real time, and determine the maximum operating time for transporting the coagulant raw material to the finished product storage bin at a first transmission speed v1 based on the unloading speed of the unloading equipment below the finished product storage bin and the maximum storage capacity of the finished product storage bin, until the material level in the finished product storage bin reaches the maximum storage capacity;

[0033] Step 300: After the material level in the finished product storage bin reaches the maximum storage capacity, regulating the first conveying device to transfer the coagulant raw material to a second speed v2, wherein the second conveying speed v2 is the same as the unloading speed of the unloading device below the finished product storage bin;

[0034] Step 400: Calculate the time required to empty the finished product storage bin based on the volume of the finished product storage bin and the density of the stored coagulant, and determine the time point when the first conveying equipment, the coagulant preparation equipment, and the second conveying equipment stop transmission in combination with the gypsum board preparation process.

[0035] As a preferred embodiment of the present invention, in step 200, the second conveying device always maintains a rated conveying efficiency during the batching of the coagulant, and the conveying amount of the second conveying device per unit time is the same as the preparation amount of the coagulant preparation device per unit time;

[0036] Determine the correspondence between the rated conveying efficiency of the second conveying device and the first transmission speed v1 of the first conveying device based on the real-time material level of the finished product storage bin, the unloading speed of the unloading device below the finished product storage bin, and the rated conveying efficiency of the second conveying device connected to the feeding port above the finished product storage bin;

[0037] Combined with the correspondence between the rated conveying efficiency of the second conveying equipment and the maximum storage capacity of the finished product storage bin and the unloading speed of the unloading equipment below the finished product storage bin, and then combined with the correspondence between the rated conveying efficiency of the second conveying equipment and the first transmission speed v1 of the first conveying equipment, the functional relationship between the first transmission speed v1 of the first conveying equipment and the maximum storage capacity of the finished product storage bin and the unloading speed of the unloading equipment below the finished product storage bin is determined. Based on the functional relationship, the maximum operating time corresponding to the time when the coagulant raw material is transported to the finished product storage bin at the first transmission speed v1 and reaches the maximum storage capacity is determined.

[0038] As a preferred solution of the present invention, in step 300, when the second transmission speed v2 of the first conveying equipment for the coagulant raw material is the same as the unloading speed of the unloading equipment below the finished product storage bin, the material level in the finished product storage bin maintains the maximum storage capacity.

[0039] As a preferred solution of the present invention, the system device of the coagulant ingredient is shut down earlier than the gypsum board preparation device, and the system device of the coagulant ingredient is started and stopped only once in the gypsum board preparation process.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] The present invention matches the preparation of the coagulant, the addition of the coagulant, and the transportation of the coagulant raw materials with the production speed of the gypsum board, so that the coagulant preparation equipment does not need to be frequently started and stopped during production, and also matches the amount of finished coagulant prepared by the coagulant preparation equipment with the demand for gypsum board preparation, thereby ensuring the continuity of the entire gypsum board production.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] like Figure 1 and Figure 2As shown, the present invention provides a coagulant ingredient preparation system, comprising: a raw material storage bin 1, a first conveying device 2, a coagulant preparation device 3, a second conveying device 4 and a finished product storage bin 8 arranged in sequence according to the production order, the coagulant produced by the coagulant preparation device 3 is transmitted to the finished product storage bin 8 via the second conveying device 4, and the coagulant in the finished product storage bin 8 is transferred to the gypsum board preparation system via the unloading device 5 below the finished product storage bin 8.

[0050] Among them, the first conveying equipment 2, the coagulant preparation equipment 3, the second conveying equipment 4 and the unloading equipment 5 are all connected to a control unit, and the control units of the first conveying equipment 2, the coagulant preparation equipment 3, the second conveying equipment 4 and the unloading equipment 5 constitute a linkage control system 6.

[0051] The linkage control system 6 calculates the output rate of the material discharge device 5 and the material discharge amount of the material discharge device 5 per unit time based on the unit addition amount of the coagulant required by the gypsum board preparation system.

[0052] The linkage control system 6 regulates the coagulant transmission amount of the second conveying device 4 per unit time to be the same as the preparation amount of the coagulant preparation device 3 per unit time based on the preparation amount of the coagulant preparation device 3 per unit time, and determines the transmission rate corresponding to the first conveying device 2.

[0053] The linkage control system 6 constructs a matching relationship between the output rate of the unloading equipment 5, the transmission rate of the second conveying equipment 4, the preparation efficiency of the coagulant preparation equipment 3 and the transmission rate of the first conveying equipment 2, so that when the output rate of the unloading equipment 5 is adjusted, the transmission rate of the first conveying equipment 2 can be automatically adjusted in linkage.

[0054] This embodiment can match the preparation of the coagulant, the addition of the coagulant, and the transportation of the coagulant raw materials with the production speed of the gypsum board, so that the coagulant preparation equipment will not be frequently started and stopped during production, and the amount of finished coagulant prepared by the coagulant preparation equipment is matched with the demand for gypsum board preparation, thereby ensuring the continuity of the entire gypsum board production.

[0055] Specifically, this embodiment first constructs the relationship between the coagulant preparation equipment 3 and the second conveying equipment 4 connected to its outlet, determines that the transmission rate of the second conveying equipment 4 is the same as the preparation rate of the coagulant preparation equipment 3, and further determines the preparation efficiency of the coagulant preparation equipment 3 per unit time based on the ratio between the finished product output and the raw material input of the coagulant preparation equipment 3 per unit time, and then determines the matching relationship between the transmission rate of the first conveying equipment 2 and the transmission rate of the second conveying equipment 4, and finally determines the matching relationship between the transmission rate of the first conveying equipment 2 and the output rate of the unloading equipment 5 based on the matching relationship between the transmission rate of the second conveying equipment 4 and the output rate of the unloading equipment 5.

[0056] Based on the demand for accelerator by the gypsum board preparation system, the output rate of the unloading equipment 5 is determined, and based on the matching relationship between the output rate of the unloading equipment 5, the transmission rate of the second conveying equipment 4, the preparation efficiency of the accelerator preparation equipment 3 and the transmission rate of the first conveying equipment 2, the transmission rate of the second conveying equipment 4, the preparation efficiency of the accelerator preparation equipment 3 and the transmission rate of the first conveying equipment 2 are further determined.

[0057] That is to say, in this embodiment, a matching relationship is established between the preparation of the coagulant (including the addition of raw materials for the coagulant and the preparation of the coagulant) and the addition of the coagulant (specifically the unloading of the stored coagulant) and the gypsum board production and preparation system, so that based on the use requirements of the gypsum board production and preparation system, the preparation of the coagulant and the addition of the coagulant are calculated and determined. On the one hand, the problem of excessive production of coagulants leading to the failure of auxiliary materials is avoided. On the other hand, the entire process requires the transmission rate of the second conveying equipment 4, the preparation efficiency of the coagulant preparation equipment 3 and the transmission rate of the first conveying equipment 2 to be variable frequency operation, without frequent start and stop, thereby improving the service life of the entire coagulant preparation device.

[0058] That is, the linkage control system 6 includes: an early-stage material storage production management module 61 , a mid-stage balancing production management module 62 , and a late-stage material discharge production management module 63 .

[0059] The early stage material storage production management module 61 regulates the coagulant preparation equipment 3 to operate at the maximum preparation efficiency until the material level in the finished product storage bin 8 reaches the maximum set value.

[0060] The mid-term balanced production management module 62 regulates the preparation efficiency of the coagulant preparation equipment 3 until the transmission volume of the second conveying equipment 4 per unit time is the same as the discharge volume of the discharge equipment 5 per minute, so that the material level in the finished product storage bin 8 is constant at the maximum set value.

[0061] The post-discharging production management module 63 calculates the time required to empty the finished product storage bin 8 according to the volume of the finished product storage bin 8 and the density of the stored coagulant, and determines the time point when the first conveying device 2 stops transmitting in combination with the gypsum board preparation process.

[0062] In order to ensure the continuity of the entire gypsum board production, this implementation method constructs the following workflow:

[0063] When the coagulant is first prepared, it is a high-speed production stage. At this time, the working speeds of the first conveying equipment 2 and the coagulant preparation equipment 3 are high. At this time, the coagulant transmission amount of the second conveying equipment 4 per unit time is greater than the discharge amount of the unloading equipment 5 per unit time. Therefore, the excess coagulant will accumulate in the finished product storage bin 8. Based on the matching relationship between the discharge rate of the unloading equipment 5 and the transmission rate of the first conveying equipment 2, the time point corresponding to the maximum set value of the accumulation of excess coagulant in the finished product storage bin 8 is determined. When the timing reaches this time point, the working speeds of the first conveying equipment 2, the coagulant preparation equipment 3 and the second conveying equipment 4 are adjusted.

[0064] When the accumulation amount of excess coagulant in the finished product storage bin 8 is the maximum set value, it is the steady-speed production stage. At this time, the transmission rate of the second conveying equipment 4 is the same as the unloading rate of the unloading equipment 5, and then the preparation efficiency of the coagulant preparation equipment 3 is the same as the transmission rate of the second conveying equipment 4, and then based on the matching relationship between the output rate of the unloading equipment 5 and the transmission rate of the first conveying equipment 2, the working rate of the first conveying equipment 2 is determined.

[0065] After determining the preparation time of the gypsum board preparation process, it is necessary to further determine the time point when the first conveying equipment 2 stops conveying. In order to ensure that the coagulant stored in the finished product storage bin 8 can be fully utilized and avoid the stored coagulant from absorbing water and becoming ineffective, this embodiment further determines the volume of the finished product storage bin 8 and the density of the stored coagulant, calculates the time required to empty the finished product storage bin 8, and determines the time point when the first conveying equipment 2 stops conveying in combination with the gypsum board preparation process.

[0066] Among them, the high-speed production stage quickly produces the coagulant, which is accumulated in the finished product storage bin 8, and can flexibly respond to the gypsum board preparation system's demand for the coagulant. At this time, it is only necessary to adjust the unloading frequency of the unloading equipment per unit time, and there is no need to frequently adjust the rate of the entire coagulant preparation and transportation system.

[0067] The switching between the early stage material storage production management module 61 and the mid-term balance production management module 62 is triggered by the timer 7. The specific time point when the timer 7 triggers the switching from the early stage material storage production management module 61 to the mid-term balance production management module 62 is:

[0068] B*t=A*t+30%*R;

[0069] t = (30% * R) / (BA);

[0070] Wherein, B is the maximum delivery amount of the coagulant by the second delivery device 4 per unit time, which is considered to be the same as the coagulant preparation amount of the coagulant preparation device 3 per unit time;

[0071] A is the material discharge amount per minute corresponding to each output rate of the material discharge device 5;

[0072] R is the maximum storage capacity of the finished product storage bin 8.

[0073] t is the triggering time point for switching from the early-stage material storage production management module 61 to the mid-term balance production management module 62 to switch the preparation rate of the coagulant preparation device 3 and the transmission rate of the second conveying device 4.

[0074] Since the second conveying device 4 is used to input the coagulant into the storage bin 8, and the unloading device 5 is used to transfer the coagulant in the storage bin 8 to the gypsum board preparation system, this embodiment first constructs a corresponding relationship between the transmission rates of the second conveying device 4 and the unloading device 5.

[0075] At this time, it is the control program of the early storage production management module 61, which is the high-speed production stage. Therefore, B is the maximum delivery amount of the coagulant by the second conveying equipment 4 per unit time, which is considered to be the same as the coagulant preparation amount of the coagulant preparation equipment 3 per unit time. After the high-speed production stage, the coagulant will be quickly accumulated in the storage bin 8.

[0076] The relationship between the transmission efficiency of the first conveying device 2 and the transmission efficiency of the second conveying device 4 is further constructed:

[0077] B=ɑ*B';

[0078] t=(30%*R) / (ɑ*B'-A);

[0079] Wherein, B' is the raw material conveying amount of the first conveying device 2 per unit time, ɑ is the preparation efficiency of the coagulant preparation device 3 per unit time, ɑ is the ratio of the preparation discharge amount of the coagulant preparation device 3 per unit time to the preparation input amount of the coagulant preparation device 3 per unit time, and ɑ<1;

[0080] At this time, it is the control program of the early material storage production management module 61, which is the high-speed production stage. By first constructing the corresponding relationship between the transmission rate of the second conveying equipment 4 and the unloading equipment 5, and then constructing the corresponding relationship between the transmission rate of the first conveying equipment 2 and the second conveying equipment 4, the matching relationship between the transmission rate of the first conveying equipment 2 and the transmission rate of the unloading equipment 5 is further determined.

[0081] When the accumulation amount of excess coagulant in the finished product storage bin 8 is the maximum set value, it is the steady-speed production stage, and the mid-term balanced production management module 62 is used to adjust the transmission rate of the second conveying equipment 4 and the unloading equipment 5 to be the same. At this time, the finished product storage bin 8 always maintains the accumulation amount at the maximum set value according to the first-in-first-out principle.

[0082] The mid-term balance production management module 62 controls B*t=A*t, and ɑ*B'=A, where B'=A / ɑ;

[0083] The raw material conveying amount of the first conveying device 2 per unit time is A / ɑ, and the mid-term balanced production management module 62 regulates the transmission rate of the first conveying device 2 based on the raw material conveying amount of the first conveying device 2 per unit time.

[0084] Since excess coagulant accumulates in the finished product storage bin 8, in order to ensure that the accumulated excess coagulant can be used for the gypsum board preparation work, the later discharge production management module 63 determines the time point t3 = t2-t1 for shutting down the transmission of the first conveying equipment 2, the coagulant preparation equipment 3 and the second conveying equipment 4 based on the time t1 required to empty the finished product storage bin 8 and the production stop time t2 of the entire gypsum board preparation process.

[0085] The unloading device 5 stops moving at the production stop time t2 of the entire gypsum board preparation process.

[0086] That is to say, in this embodiment, based on the production stop time point t2 of the gypsum board preparation system, the accelerator preparation system is shut down in advance, and when the time t1 required to empty the finished product storage bin 8 is calculated, the transmission rate of the unloading equipment 5 remains unchanged.

[0087] In addition, the present invention also discloses an adaptive control method of the above-mentioned coagulant ingredient adaptive control system, comprising the following steps:

[0088] Step 100: Based on the gypsum board preparation process, determine the amount of coagulant added per unit time, and adjust the unloading amount of the finished product storage bin per unit time to be the same as the amount of coagulant added per unit time;

[0089] Step 200: Monitor the material level in the finished product storage bin in real time, and determine the maximum operating time for transporting the coagulant raw material to the finished product storage bin at a first transmission speed v1 based on the unloading speed of the unloading equipment below the finished product storage bin and the maximum storage capacity of the finished product storage bin, until the material level in the finished product storage bin reaches the maximum storage capacity;

[0090] Step 300: After the material level in the finished product storage bin reaches the maximum storage capacity, the second conveying speed v2 of the first conveying device for the coagulant raw material is adjusted, and the second conveying speed v2 is the same as the unloading speed of the unloading device below the finished product storage bin;

[0091] Step 400: Calculate the time required to empty the finished product storage bin based on the volume of the finished product storage bin and the density of the stored coagulant, and determine the time point at which the first conveying device, the coagulant preparation device, and the second conveying device stop transmission in combination with the gypsum board preparation process.

[0092] Similarly, in order to establish a matching relationship between the preparation of the coagulant (including the addition of coagulant raw materials and the preparation of the coagulant), the addition of the coagulant (specifically the unloading of the stored coagulant) and the gypsum board production and preparation system, so that the coagulant preparation equipment will not be frequently started and stopped during production, and the amount of finished coagulant prepared by the coagulant preparation equipment is matched with the demand for gypsum board preparation, thereby ensuring the continuity of the entire gypsum board production, this embodiment couples the first conveying equipment, the coagulant preparation equipment and the second conveying equipment to avoid the coagulant preparation efficiency failing to meet the needs of the gypsum board preparation system, and also to avoid the problem of storage failure caused by excessive preparation of coagulant.

[0093] In step 200, the second conveying device always maintains a rated conveying efficiency during the batching of the coagulant, and the conveying amount of the second conveying device per unit time is the same as the preparation amount of the coagulant preparation device per unit time;

[0094] Determine the correspondence between the rated conveying efficiency of the second conveying device and the first conveying speed v1 of the first conveying device based on the real-time material level of the finished product storage bin, the unloading speed of the unloading device below the finished product storage bin, and the rated conveying efficiency of the second conveying device connected to the inlet above the finished product storage bin;

[0095] Combined with the correspondence between the rated conveying efficiency of the second conveying equipment and the maximum storage capacity of the finished product storage bin and the unloading speed of the unloading equipment below the finished product storage bin, and then combined with the correspondence between the rated conveying efficiency of the second conveying equipment and the first transmission speed v1 of the first conveying equipment, the functional relationship between the first transmission speed v1 of the first conveying equipment and the maximum storage capacity of the finished product storage bin and the unloading speed of the unloading equipment below the finished product storage bin is determined. Based on the functional relationship, the maximum operating time corresponding to transporting the coagulant raw material to the finished product storage bin at the first transmission speed v1 to reach the maximum storage capacity is determined.

[0096] In step 300, when the second transmission speed v2 of the first conveying device for the coagulant raw material is the same as the unloading speed of the unloading device below the finished product storage bin, the material level in the finished product storage bin maintains the maximum storage capacity.

[0097] The system device for coagulant batching is shut down earlier than the gypsum board preparation device, and the system device for coagulant batching is started and stopped only once in the gypsum board preparation process.
