[0006] To achieve the above object, the present invention provides a method for preparing a green energy-saving integrated bricklaying and plugging material, comprising the following steps:

For the water-added mixed raw materials that meet the primary judgment conditions, a secondary judgment is made on whether the stirring stage is reached by using the data collected by the imaging device.
[0013] Furthermore, raw materials from different feed ports are concentrated and mixed, dust generated during the mixing process is irradiated with infrared rays, the dust content is determined based on the intensity of scattered light, and the dust extraction speed of the dust removal device is adjusted based on the dust content.
[0014] Furthermore, a fluctuation analysis is performed on the primary torque change curve, and whether to perform secondary stirring is determined based on the fluctuation analysis result of the primary torque change curve.
[0015] Furthermore, by performing a secondary uniformity evaluation value analysis on the secondary torque change curve, the secondary stirring stage is divided into a block forming stage, a stirring stage and a dilution stage according to the analysis result.
[0016] Furthermore, in the agglomeration stage, the first stirring rod stirs the mixed raw materials, and the first stirring rod adjusts the rotation speed of the first stirring rod according to the first torque collected by the first torque sensor.
[0017] Furthermore, the first torque change curve is generated through the first torque value, the first torque change curve within the first unit time is analyzed, a primary determination is made on whether to enter the stirring stage based on the analysis result, and a secondary determination is made on whether to start the stirring stage based on the determination result.
[0018] Furthermore, based on the secondary determination condition for starting the stirring stage, the number of agglomeration points of the mixed raw material collected by the imaging device is determined, and whether to start the stirring stage is determined according to the determination result of the number of agglomeration points.
[0019] Furthermore, based on the stirring stage, the first stirring rod is retracted, the second stirring rod is stirring, the second torque is collected by the second torque sensor, a second torque change curve is generated based on the second torque, a smoothness analysis is performed on the second torque change curve, and whether the dilution stage is reached is determined based on the smoothness analysis result.

[0021] A device suitable for a green energy-saving integrated bricklaying and plugging material preparation method, comprising:
[0022] Prepare the tank, which is set in the first section of the production equipment and is used to wash, dry, crush and screen the raw materials;
[0023] A stirring tank body, which is arranged at the tail end of the production equipment and has a head end connected to the tail end of the preparation tank body, and is used to mix and stir the raw materials;
[0024] A photoelectric detector, which is installed at the rear end of the preparation tank and is used to measure the content of dust generated by the mixing operation;
[0025] An infrared laser, which is installed at the head end of the preparation tank, is used to output infrared rays and cooperate with the photoelectric detector to measure the dust content;
[0026] A dust removal device, which is arranged on the top of the preparation tank body and is used to remove dust;
[0027] An imaging device, which is arranged on the top of the stirring tank and is used to image the agglomeration of the mixture in the agglomeration stage;
[0028] A stirring device, which is arranged inside the stirring tank body and is used to stir and mix the raw materials, including a first stirring rod arranged vertically and a second stirring rod arranged around the first stirring rod;
[0029] A fusion agent spraying device, which is arranged on the top of the stirring tank body and is used to add fusion agent during the secondary stirring process;
[0030] The torque sensor group is used for detecting the torque of the stirring device, and includes: a first torque sensor for detecting the first stirring rod and a second torque sensor for detecting the second stirring rod.
[0031] Compared with the prior art, the beneficial effect of the present invention lies in that the rotation speed of the dust collecting device is limited by setting the first extraction speed of the dust collecting device and the second extraction speed of the dust collecting device. When the rotation speed of the dust collecting device is less than the first extraction speed of the dust collecting device, the first extraction speed of the dust collecting device is selected as the rotation speed of the dust collecting device, which can avoid the situation where the rotation speed of the dust collecting device is too slow to form effective suction to remove dust due to too low dust content. When the rotation speed of the dust collecting device is greater than or equal to the first extraction speed of the dust collecting device and less than the second extraction speed, the second extraction speed of the dust collecting device is selected as the rotation speed of the dust collecting device, which can avoid the situation where the rotation speed is too fast due to excessive dust content, exceeding the maximum dust removal efficiency of the dust collecting device, resulting in some dust being unable to be effectively removed. The dust collecting device can also maintain a reasonable rotation speed and extend its service life.
[0032] Furthermore, the stirring process is divided into two parts, namely primary stirring and secondary stirring. The fluctuation change of the primary torque change curve is analyzed for the primary stirring process. The primary torque change curve is segmented according to unit time, and the slope of each segmented primary torque change curve is compared with the preset first-class standard smooth slope to obtain the slope of any segmented primary torque change curve. When the slope of the first-class torque change segmented curve satisfies the first-class standard smooth slope that is greater than zero and less than or equal to the first-class standard, the primary stirring stops. When the first-class stirring stop condition is met, the change amplitude of the first torque sensor data tends to be gentle, indicating that the raw materials are mixed evenly, avoiding substandard product quality due to insufficient mixing of the raw materials. The primary stirring is to fully mix different raw materials.
[0033] Furthermore, the rotation speed of the first stirring rod is limited by the first torque collected by the first torque sensor. When the first torque is less than the first torque value of the first stage in the block forming stage, the compensation parameter of the first torque value on the rotation speed of the first stirring rod increases, and the rotation speed of the first stirring rod is increased to improve the stirring efficiency. When the first torque value is greater than or equal to the first torque value of the second stage in the block forming stage, it can avoid that when the first torque value is too large, if the rotation speed of the first stirring rod does not change, the first stirring rod will be easily damaged, which increases the maintenance time, resulting in an increase in stirring time and affecting the stirring efficiency.
[0034] Furthermore, by performing graded judgment on the block forming stage, the first torque change curve is generated through the first torque value, the first torque change curve is analyzed per unit time, and a judgment is made on whether to enter the block forming stage according to the analysis result. When the slope of the first torque change curve of the block forming stage segment is greater than the second standard smooth slope, the first stirring rod continues to stir the mixed raw materials in the block forming stage, which can indicate that the mixed raw materials and water are not sufficiently stirred in the block forming stage, thereby avoiding the quality degradation of the finished product due to insufficient stirring. When the slope of the first torque change curve of the block forming stage segment is greater than zero and less than or equal to the second standard smooth slope, the data collected by the imaging device is analyzed to determine whether to start the stirring stage, thereby avoiding the existence of agglomeration points in the block forming stage that affect the next operation process.
[0035] Furthermore, a second torque change curve is generated according to the second torque collected by the second torque sensor, and the second torque change curve is analyzed, the second torque change curve is segmented according to the second unit time, and the slope of the second torque change curve of each segment is generated. When the slope of the second torque change curve of each segment is greater than zero and less than or equal to the second standard smooth slope, the stirring stage is stopped and the dilution stage is started. This can avoid the next step of stirring due to the uniformity of the mixed raw materials not meeting the requirements, resulting in a decrease in product quality, and better stir the mixture.
[0036] Furthermore, in the dilution stage, in order to better mix the mixed raw materials and water, the torque applied to the first stirring rod and the second stirring rod respectively generates a primary torque change curve and a secondary torque change curve in the dilution stage, and the similarity of the two curves is analyzed. If the similarity of the two curves is greater than zero and less than or equal to the similarity interval of the first curve, it means that the uniformity of the mixing of the mixed raw materials and water in the dilution stage meets the standard, and the mixed raw materials and water in the dilution stage can be more fully stirred.

[0046] This embodiment provides a method for preparing a green and energy-saving integrated bricklaying and plugging material, comprising the following steps:
[0047] Step S100, washing, drying, crushing and screening the selected raw materials through a preparation tank, and mixing and stirring the screened mixed raw materials in a stirring tank through a stirring rod;
[0048] Step S200, performing dust removal treatment on the dust generated during the mixing process of the mixed raw materials;
[0049] Step S300, performing primary stirring on the mixed raw material after the dust removal treatment, wherein the primary stirring is dry stirring without adding water to the mixed raw material, generating a primary torque change curve based on the first torque sensor in the primary stirring, analyzing the stability of the primary torque change curve, and determining whether to start the secondary stirring based on the analysis result;
[0050] Step S400, generating a second-level uniformity evaluation value of the mixed raw material based on the secondary torque change curve and the amount of water added, and determining the agglomeration stage, the stirring stage, and the dilution stage according to a comparison result between the second-level uniformity evaluation value and a preset standard second-level uniformity evaluation value;
[0051] Step S500, determining the rotation speed of the first stirring rod based on the first torque collected by the first torque sensor in the agglomeration stage;
[0052] Step S600, generating a first torque change curve through the data collected by the first torque sensor in the block forming stage, and making a primary judgment on whether the stirring stage is reached by comparing the first torque change curve with a preset first torque change value. For the water-added mixed raw materials that meet the primary judgment conditions, a secondary judgment is made on whether the stirring stage is reached by using the data collected by the imaging device.
[0053] Specifically, raw materials from different feed ports are concentrated and mixed, dust generated during the mixing process is irradiated with infrared rays, the dust content is determined based on the intensity of scattered light, and the dust extraction speed of the dust removal device is adjusted based on the dust content.
[0054] The infrared laser emits infrared rays, which pass through the dust formed in the mixed raw material area. The infrared rays refracted by the dust are received by the photoelectric detector to generate scattered light intensity P. The extraction speed of the dust removal device V = P × Q, where Q is a compensation parameter for the influence of the scattered light intensity on the extraction speed of the dust removal device;
[0055] Set the first extraction speed V1 of the dust removal device and the second extraction speed V2 of the dust removal device.
[0056] If V<V1, the first extraction speed V1 of the dust removal device is selected as the extraction speed of the dust removal device;
[0057] If V1≤V<V2, the extraction speed V of the dust removal device is selected as the extraction speed of the dust removal device;
[0058] If V≥V2, the second extraction speed V2 of the dust removal device is selected as the extraction speed of the dust removal device.
[0059] The rotation speed of the dust collector is limited by setting the first extraction speed and the second extraction speed of the dust collector. When the rotation speed of the dust collector is less than the first extraction speed of the dust collector, the first extraction speed of the dust collector is selected as the rotation speed of the dust collector. This can prevent the dust collector from rotating too slowly due to the low dust content and unable to form effective suction to remove dust. When the rotation speed of the dust collector is greater than or equal to the first extraction speed and less than the second extraction speed, the second extraction speed of the dust collector is selected as the rotation speed of the dust collector. This can prevent the dust content from being too high due to the rotation speed being too fast, exceeding the maximum dust removal efficiency of the dust collector, resulting in some dust being unable to be effectively removed. This can also allow the dust collector to maintain a reasonable rotation speed and extend its service life.
[0060] Specifically, a fluctuation analysis is performed on the primary torque change curve, and whether to perform secondary stirring is determined based on the fluctuation analysis result of the primary torque change curve.
[0061] When performing primary stirring, the first torque sensor detects that the torque value on the first stirring rod is Na, and generates a primary torque change curve F(Na) according to the torque value on the first stirring rod during primary stirring. The primary torque change curve F(Na) is segmented according to the first unit time Ta, the first segmented primary torque change curve F1(Na), the second segmented primary torque change curve F2(Na), ..., the nth segmented primary torque change curve Fn(Na),
[0062] Select any segmented primary torque change curve Fi(Na), i=1,2,3,...,n,
[0063] Based on any segmented primary torque change curve Fi(Na), obtain the slope Ki of any segmented primary torque change curve Fi(Na),
[0064] Set the first-class standard smoothing slope Ka1,
[0065] When Ki>Ka1, the first stirring rod continues to stir the mixed raw materials in the first stirring stage;
[0066] When 0<Ki≤Ka1, the first-stage stirring operation is stopped and the second-stage stirring is started.
[0067] The stirring process is divided into two parts, namely primary stirring and secondary stirring. The fluctuation change of the primary torque change curve is analyzed for the primary stirring process. The primary torque change curve is segmented according to unit time. The slope of each segmented primary torque change curve is compared with the preset first-class standard smooth slope to obtain the slope of any segmented primary torque change curve. When the slope of the first-class torque change segmented curve satisfies the first-class standard smooth slope greater than zero and less than or equal to the first-class standard, the primary stirring stops. When the first-class stirring stop condition is met, the change amplitude of the first torque sensor data tends to be flat, indicating that the raw materials are mixed evenly, avoiding substandard product quality due to insufficient mixing of the raw materials. The primary stirring is to fully mix different raw materials.
[0068] Specifically, by performing a secondary uniformity evaluation value analysis on the secondary torque change curve, the secondary stirring stage is divided into a block formation stage, a stirring stage and a dilution stage according to the analysis result.
[0069] The fusing agent described in this embodiment can be water, waterproof coating, fire retardant coating, etc., and this embodiment does not make any specific limitation.
[0070] Set the first and second level uniformity evaluation values G1 and G2
[0071] Generate a secondary torque change curve F(Nb) and water addition amount according to the data of the second torque sensor, and analyze the secondary uniformity evaluation value G, G=L×a1+D×a2, wherein L is the secondary torque value at time ti, a1 is the compensation parameter of the secondary torque value on the secondary uniformity evaluation value, D is the water spraying amount of the fusion spraying device at time ti, and a2 is the compensation parameter of the water spraying amount on the secondary uniformity evaluation value;
[0072] When G<G1, the secondary stirring stage is a block-forming stage, and the block-forming stage is a stage in which blocks are formed after the mixed raw materials are stirred with water;
[0073] When G1≤G<G2, the secondary stirring stage is the stirring stage, and the stirring stage is the stage in which the lumps are basically stirred away after the mixed raw materials and water are stirred;
[0074] When G≥G2, the secondary stirring stage is a dilution stage, and the dilution stage is a stage in which the mixed raw materials and water are stirred to completely form a mixed liquid that meets the requirements.
[0075] Specifically, in the agglomeration stage, the first stirring rod stirs the mixed raw material, and the first stirring rod adjusts the rotation speed of the first stirring rod according to the first torque collected by the first torque sensor.
[0076] In the agglomeration stage, the first stirring rod speed Va1, Va1 = Na1 × Qa, wherein Na1 is the first torque value, Qa is the compensation parameter for the influence of the first torque value on the first stirring rod speed,
[0077] The first torque value Na1 is negatively correlated with the compensation parameter Qa of the first torque value on the first stirring rod rotation speed.
[0078] Set the first torque value Na11 in the first stage of block formation, and the first torque value Na12 in the second stage of block formation.
[0079] When Na1<Na11, Qa=1.5;
[0080] When Na11≤Na1<Na12, Qa=1;
[0081] When Na1≥Na12, Qa=0.5.
[0082] The rotation speed of the first stirring rod is limited by the first torque collected by the first torque sensor. When the first torque is less than the first torque value of the first stage in the block forming stage, the compensation parameter of the first torque value on the rotation speed of the first stirring rod increases, and the rotation speed of the first stirring rod is increased to improve the stirring efficiency. When the first torque value is greater than or equal to the first torque value of the second stage in the block forming stage, it can be avoided that when the first torque value is too large, if the rotation speed of the first stirring rod does not change, the first stirring rod will be easily damaged, the maintenance time will be increased, the stirring time will be increased, and the stirring efficiency will be affected.
[0083] Specifically, the first torque change curve is generated through the first torque value, the first torque change curve within the first unit time is analyzed, a primary determination is made on whether to enter the stirring stage based on the analysis result, and a secondary determination is made on whether to start the stirring stage based on the determination result.
[0084] During the block forming stage, the first torque sensor detects that the torque value on the first stirring rod is Na1, and generates a first torque change curve F(Na1) according to the torque value on the first stirring rod during the block forming stage. The first torque change curve F(Na1) is segmented according to the first unit time Ta, and the first torque change curve F1(Na1) is segmented into the first segment in the block forming stage, the first torque change curve F2(Na1) is segmented into the second segment in the block forming stage, ..., the first torque change curve Fn(Na1) is segmented into the nth segment in the block forming stage.
[0085] Select any first torque change curve Fm(Na1) of the block stage, m=1,2,3,...,n,
[0086] Based on any block-forming stage segmented first torque change curve Fm(Na1), obtain the slope Km of any block-forming stage segmented first torque change curve Fm(Na1),
[0087] Set the second standard smoothing slope Ka2,
[0088] When Km>Ka2, the first stirring rod continues to stir the mixed raw materials in the agglomeration stage;
[0089] When 0<Km≤Ka2, the data collected by the imaging device is analyzed to determine whether to start the stirring stage.
[0090] Specifically, based on the secondary determination condition for starting the stirring stage, the number of agglomeration points of the mixed raw material collected by the imaging device is determined, and whether to start the stirring stage is determined according to the determination result of the number of agglomeration points.
[0091] The imaging device is provided with a standard imaging point Z1.
[0092] Analyze the number of agglomeration points Z collected by the imaging device,
[0093] If Z>Z1, the first stirring rod continues to stir the mixed raw materials in the agglomeration stage;
[0094] If 0≤Z≤Z1, the stirring phase is started.
[0095] By performing graded judgment on the agglomeration stage, the first torque change curve is generated through the first torque value, and the first torque change curve per unit time is analyzed. A judgment is made on whether to enter the agglomeration stage according to the analysis result. When the slope of the first torque change curve of the agglomeration stage segment is greater than the second-class standard smooth slope, the first stirring rod continues to stir the mixed raw materials in the agglomeration stage, which can indicate that the mixed raw materials and water are not sufficiently stirred in the agglomeration stage, thereby avoiding the quality reduction of the finished product due to insufficient stirring. When the slope of the first torque change curve of the agglomeration stage segment is greater than zero and less than or equal to the second-class standard smooth slope, the data collected by the imaging device is analyzed to determine whether to start the stirring stage, thereby avoiding the existence of agglomeration points in the agglomeration stage affecting the next operation process.
[0096] Specifically, based on the stirring stage, the first stirring rod is retracted, the second stirring rod is stirring, the second torque is collected by the second torque sensor, a second torque change curve is generated based on the second torque, a smoothness analysis is performed on the second torque change curve, and whether the dilution stage is reached is determined based on the smoothness analysis result.
[0097] The second torque collected by the second torque sensor is Nb, and a second torque change curve F(Nb) is generated according to the second torque Nb. The second torque change curve F(Nb) is segmented according to the second unit time Tb, the first segment second torque change curve F1(Nb), the second segment second torque change curve F2(Nb), ..., the n'th segment second torque change curve Fn(Nb), wherein Tb=0.6Ta,
[0098] Select any segmented second torque change curve Fi(Nb), i=1,2,3,...,n`,
[0099] Based on any segmented second torque change curve Fi(Nb), obtain the slope Kib of any segmented second torque change curve Fi(Nb),
[0100] Set the second standard smoothing slope Kb1,
[0101] When Kib>Kb1, the second stirring rod continues to stir the mixed raw materials in the stirring stage;
[0102] When 0<Kib≤Kb1, the stirring stage is stopped and the dilution stage is started.
[0103] During the stirring stage, a second torque change curve is generated according to the second torque collected by the second torque sensor, and the second torque change curve is analyzed. The second torque change curve is segmented according to the second unit time, and the slope of the second torque change curve of each segment is generated. When the slope of the second torque change curve of each segment is greater than zero and less than or equal to the second standard smooth slope, the stirring stage is stopped and the dilution stage is started. This can avoid the next stirring step due to the uniformity of the mixed raw materials not meeting the requirements, resulting in a decrease in product quality, and better stir the mixture.
[0104] Specifically, the mixed raw material enters the dilution stage, the first stirring rod and the second stirring rod are stirred simultaneously, the first torque change curve and the second torque change curve are analyzed for similarity, and whether to stop the dilution stage is determined based on the analysis result.
[0105] The similarity C of the primary torque change curve F2(Na)` and the secondary torque change curve F2(Nb)` in the dilution stage is analyzed, C = F2(Na)` / F2(Nb)`
[0106] Set the first curve similarity C1,
[0107] If C>C1, the stirring device continues to stir during the dilution stage;
[0108] If 0<C≤C1, the stirring device stops stirring in the dilution stage.
[0109] In the dilution stage, in order to better mix the mixed raw materials and water, the torques applied to the first stirring rod and the second stirring rod are respectively used to generate a primary torque change curve and a secondary torque change curve in the dilution stage, and the similarity of the two curves is analyzed. If the similarity of the two curves is greater than zero and less than or equal to the similarity interval of the first curve, it means that the uniformity of the mixing of the mixed raw materials and water in the dilution stage has reached the standard, and the mixed raw materials and water in the dilution stage can be more fully stirred.

The infrared laser irradiates the dust generated during the mixing of each raw material, the photoelectric detector measures the dust content, and the dust removal device adjusts the extraction speed according to the dust content measurement data to absorb the dust. The first stirring rod performs primary stirring on each mixed raw material. After the stirring is completed, the fusion agent spraying device sprays water to enter the secondary stirring. The secondary stirring is divided into agglomeration stage, stirring stage and dilution stage according to the uniformity value of the mixed raw material. The first stirring rod stirs in the agglomeration stage, and the imaging device monitors the number of agglomerates. After meeting the standards, the first stirring rod is retracted, and the second stirring rod works in the stirring stage. When the stirring stage meets the standards, it enters the dilution stage, and the first stirring rod and the second stirring rod stir the mixed raw materials in the dilution stage until the stop conditions are met.
