The following explains the method for controlling the slag tapping of the vertical shaft in the embodiment of the invention in detail.
The embodiment of the invention provides a pneumatic conveying system which is used for realizing slag discharge treatment under the working condition of a vertical shaft. Fig. 2 is a schematic diagram of a pneumatic conveying system under shaft conditions in an embodiment of the present invention, as shown in fig. 2, taking a full-section shaft condition as an example, the system includes: the device comprises a heading machine cutterhead (1), a first slag quantity detection sensor (2), an airflow slag collecting device (3), a pressure sensor (4), an air inlet (5), a slag suction port (6), a distance sensor (7), a transmission pipeline (8), a slag storage tank (9), a second slag quantity detection sensor (10), a fan (11), a frequency sensor (12), a bucket (13), a speed sensor (14), a lifting rope (15), a pressure sensor (16) and a third slag quantity detection sensor (17).
As shown in fig. 2, the heading machine cutterhead (1) is used for digging out dregs in a vertical shaft, the airflow dreg collecting device (3) is arranged in the vertical shaft and used for storing dregs which are newly dug by the heading machine, the first side of the airflow dreg collecting device (3) is arranged at the bottom of the heading machine cutterhead, the first dreg quantity detection sensor (2) is arranged at one side of the airflow dreg collecting device (3) which is close to the heading machine cutterhead (1), the dreg suction port (6) is arranged on one side of the conveying pipeline (8) which is close to the airflow dreg collecting device (3), the conveying pipeline (8) can move up and down, the direction of the conveying pipeline (8) which extends outwards of the vertical shaft is connected with the dreg storage tank (9), the conveying pipeline (8) is further provided with a fan (11) through the direction of the dreg storage tank (9) which extends outwards of the vertical shaft, and the conveying pipeline (8) is used for conveying dregs dug by the heading machine cutterhead to a position which is far away from the heading machine cutterhead.
When the pneumatic conveying system operates, high-pressure gas enters the airflow slag collecting device (3) through the air inlet (5) to generate high-speed high-pressure airflow, and the airflow concentrates slag soil and slag stones at the bottom of the heading machine cutterhead (1) to the pneumatic conveying slag absorbing port (6). The fan (11) generates negative pressure high-speed airflow, slag at the slag suction port (6) is sucked to the slag storage tank (9) through the transmission pipeline (8), then the slag is transferred to the bucket (13) through the slag storage tank (9), the bucket (13) is transferred to the well under the traction of the lifting rope (15), and the whole process is completed for slag discharge of slag and slag under the working condition of a vertical shaft.
In the process, a first slag quantity detection sensor (2) is used for collecting actual excavation quantity, a pressure sensor (4) is used for collecting gas pressure of an airflow slag collecting device (3), a distance sensor (7) is used for collecting a slag suction opening height range, the slag suction opening height range reflects the distance from a slag suction opening to a cutter head of a heading machine, a second slag quantity detection sensor (10) is used for collecting actual slag quantity, a speed sensor (14) is used for collecting slag stone lifting and transferring speed, and a frequency sensor (12) is used for collecting operation frequency of a fan (11).
Based on the pneumatic conveying system, the vertical shaft slag discharging control method is realized.
In specific implementation, the first slag amount detection sensor (2) detects the actual excavation amount according to a first preset frequency, for example, 1 signal is collected every minute, 2 signals are collected every minute, 5 signals are collected every minute, and the like, the unit of each signal can be m 3/h, the signal is the actual excavation amount, and the volume amount of the slag actually excavated by the heading machine in the first unit time can be reflected. Because the construction environment under the vertical shaft, especially near the cutterhead (1) of the heading machine is relatively bad, single-time collected signals can be wrong, and calculation is needed by referring to a plurality of collected actual excavation amounts.
Then, determining a theoretical slag output by utilizing a plurality of actual excavation quantities; the theoretical slag amount reflects a range value of the volumetric amount of slag theoretically transported out of the shaft in the first unit time.
Based on the actual excavation amount, the theoretical slag discharge amount of the externally transmitted slag soil can be approximately estimated, for example, an average value of a plurality of actual excavation amounts is taken as the theoretical slag discharge amount.
Fig. 3 is a schematic diagram of a specific embodiment of a method for controlling slag tapping in a shaft according to an embodiment of the present invention, where determining a theoretical slag tapping amount by using a plurality of actual excavation amounts may include:
Step 301, determining a theoretical excavation amount according to the tunneling speed of the tunneling machine; the theoretical excavation quantity reflects the volume quantity of slag excavated by the development machine in the first unit time in theory;
Step 302, determining a value interval of the volume of the excavated dregs in a first unit time according to a plurality of actual excavated volumes and theoretical excavated volumes;
step 303, taking a value interval of the volume quantity of the excavated slag soil in the first unit time as a theoretical slag quantity.
In the implementation, the real-time tunneling speed of the tunneling machine can be obtained through a control picture of the tunneling machine, and a theoretical excavation amount is calculated through the average tunneling speed and the cutterhead area of the tunneling machine. And combining the theoretical excavation amount with the acquired actual excavation amount to determine the real theoretical slag output. For example, weights are designed for theoretical excavation amount and collected actual excavation amount, signals are collected for multiple times, multiple average values are obtained according to the weights, and the range of theoretical slag discharge amount is determined.
In one embodiment, determining a value interval of the volume amount of the excavated slag soil in the first unit time according to the plurality of actual excavation amounts and the theoretical excavation amount may include:
And determining a value interval of the volume quantity of the excavated slag soil in the first unit time according to the theoretical excavation quantity and the maximum value and the minimum value in the actual excavation quantities.
For example, the theoretical excavation amount is 50m 3/h, the actual excavation amount comprises 30m 3/h、34m3/h、40m3/h、80m3/h、60m3/h and the like, and 30m 3/h-80m3/h is taken as the actual theoretical slag discharge amount.
It should be noted that, because the first slag amount detection sensor collects data in real time, the heading machine also works in real time, so that the data obtained by the first slag amount detection sensor and the second slag amount detection sensor also change in real time, and the theoretical slag amount is actually a changing range value.
Then, in step 103, obtaining an actual slag output through a second slag quantity detection sensor; the actual slag discharge amount reflects the volume amount of slag soil actually conveyed to the outside of the vertical shaft in the first unit time; the second slag quantity detection sensor is arranged at a position far away from the heading machine cutterhead in the transmission pipeline and is used for detecting the actual slag quantity according to a second preset frequency, and the transmission pipeline is used for conveying the slag dug by the heading machine cutterhead to a position far away from the heading machine cutterhead.
The actual slag quantity can be obtained through the second slag quantity detection sensor (10) and the third slag quantity detection sensor (17), both belong to the position far away from the cutter head of the heading machine in the transmission pipeline, and when the method is implemented, the actual slag quantity collected by the two slag quantity detection sensors can be compared and combined to determine the accurate actual slag quantity.
The slag quantity detection sensor near the heading machine cutterhead (1) and the slag quantity detection sensor far away from the heading machine cutterhead (1) can be sensors adopting different principles, because the working environment is different along with the difference of depth inside a vertical shaft, for example, the slag quantity detection sensor adopting the visual principle can be used on the ground, and the slag quantity detection sensor adopting the visual principle can be used when the slag quantity detection sensor is larger in vibration and insufficient in light near the heading machine cutterhead (1).
And then comparing the actual slag output with the theoretical slag output. Based on the result of the comparison, different measures are taken.
If the actual slag discharge amount is within the range of the theoretical slag discharge amount, normal slag discharge can be considered, and if the actual slag discharge amount is not within the range of the theoretical slag discharge amount, abnormal slag discharge is considered, and some key parameters in the vertical shaft need to be adjusted, wherein the key parameters comprise parameters influencing the slag discharge amount.
It should be noted that the real-time actual slag discharge amount of the ground is theoretically not larger than the theoretical slag discharge amount range, because the theoretical slag discharge amount is determined according to the theoretical excavation amount, the maximum value and the minimum value among the plurality of actual excavation amounts, and the slag discharge amount is not larger than the actual excavation amount. Therefore, the actual slag amount is either within the theoretical slag amount range or smaller than the minimum value of the theoretical slag amount range, and if the actual slag amount is larger than the maximum value of the theoretical slag amount range, a significant error is considered to occur, and shutdown inspection is recommended.
In one embodiment, the key parameters include, but are not limited to, one or any combination of the following:
The height of the slag suction port, the pressure of the slag suction port, the volume of the slag soil transferred in the second unit time at the inlet of the slag storage tank, the transfer speed of the slag storage tank and the air flow intensity of the slag collecting port.
The key parameters may also include operational parameters of the fan, etc.
When the actual slag output is not in the range of the theoretical slag output, acquiring the current values of a plurality of key parameters and the weight of each key parameter, wherein the key parameters comprise parameters influencing the slag output, the weights of the key parameters reflect the adjustment sequence of the key parameters, the values of the key parameters are continuously adjusted according to the current values of the key parameters and the weights of each key parameter, the actual slag output and the theoretical slag output are updated, and when the updated actual slag output is in the range of the updated theoretical slag output, the adjustment of the key parameters is stopped.
In specific implementation, when the actual slag output is not in the range value of the theoretical slag output, the conditions that slag is slowly conveyed and slag is accumulated somewhere are considered, and adjustment is carried out according to the weights of a plurality of key parameters, wherein the weights of the key parameters can be obtained according to expert experience, can be determined according to the actual working conditions in a vertical shaft, can also be determined by referring to parameter adjustment records influencing the slag output in the history, and reflect the importance degree of the key parameters, the adjustment sequence priority of the key parameters and the like.
When the parameters are adjusted, the actual slag output and the theoretical slag output can be updated at the same time, and when the updated actual slag output is within the updated theoretical slag output, the normal slag output is considered, and the adjustment of a plurality of key parameters is stopped.
In one embodiment, the weights of the key parameters are determined in advance as follows:
Determining the weight of the key parameters according to the sequence of the positions where the key parameters act on the slag soil transmission path; the muck transfer path includes a muck transfer path from the excavation to the ground.
For example, the parameters of the slag soil transmission path far away from the cutterhead of the heading machine can be adjusted preferentially, and the parameters are adjusted gradually towards the deep inside of the vertical shaft. The weight of the ground near the outside of the vertical shaft is larger, then the weight of the related key parameters is gradually reduced along the muck transmission path, and the weight of the cutterhead near the heading machine is minimum.
In one embodiment, continuously adjusting the values of the plurality of key parameters according to the current values of the plurality of key parameters and the weight of each key parameter, updating the actual slag output and the theoretical slag output, and stopping adjusting the plurality of key parameters when the updated actual slag output is within the updated theoretical slag output range, wherein the method may include:
determining a theoretical target value of the key parameter according to the theoretical slag quantity; the theoretical target value reflects an actual value of a key parameter when the actual slag discharge amount is within a range of the theoretical slag discharge amount;
Determining a key parameter adjustment scheme according to the current values of the key parameters, the weight of each key parameter and the theoretical target value of the key parameter; the key parameter adjustment scheme comprises adjustment sequences of different key parameters, different key parameters needing to be adjusted simultaneously and adjustment step sizes of the different key parameters;
according to a key parameter adjustment scheme, adjusting the values of a plurality of key parameters, and simultaneously updating the actual slag output and the theoretical slag output;
And stopping adjusting the plurality of key parameters when the updated actual slag output is within the updated theoretical slag output range.
When the method is implemented, theoretical target values of key parameters are determined according to the theoretical slag output, the theoretical target values can be a range value and reflect a reference value when the slag is normally transmitted, and the theoretical target values of the key parameters are changed in real time and are used as references for weight determination and key parameter adjustment.
In one embodiment, after the actual slag output is obtained by the second slag amount detecting sensor, the method may further include:
Continuously updating the theoretical slag output when the actual slag output is within the range value of the theoretical slag output, and continuously obtaining the actual slag output;
And comparing the actual slag output with the theoretical slag output.
In one embodiment, continuously updating the theoretical slag output and continuously acquiring the actual slag output may further include:
calculating the transfer speed of the slag storage tank according to the actual slag discharge amount and the current soil discharge efficiency of the slag storage tank; the slag storage tank is arranged at a position of the transmission pipeline, which is far away from the cutterhead of the heading machine, and is used for receiving the slag soil transmitted by the transmission pipeline and discharging the slag soil; the soil outlet efficiency reflects the efficiency of slag soil transmission of the slag storage tank;
According to the calculated transfer speed of the slag storage tank, the transfer speed of the slag storage tank is adjusted;
comparing the actual slag output with the theoretical slag output, comprising:
after the transfer speed of the slag storage tank is regulated, the actual slag output and the theoretical slag output are compared.
In the embodiment of the invention, when the actual slag discharge amount is within the range value of the theoretical slag discharge amount, observation adjustment is also needed to be implemented, so that the situation that the actual slag discharge amount is not within the range value of the theoretical slag discharge amount is prevented.
When the actual slag quantity is within the range of the theoretical slag quantity, only the relevant parameters of the slag storage tank are adjusted, the volume quantity of the slag soil transmitted in the second unit time at the inlet of the slag storage tank, which is acquired by the second slag quantity detection sensor (10) (simply referred to as the slag storage port real-time slag quantity Q), the value acquired by the second slag quantity detection sensor (10) is within the range of the theoretical target value of the parameter, at this time, the weight of the parameter of the transfer speed of the slag storage tank can be set to 90%, the weights of the remaining 10% are halved by other key parameters, namely the transfer speed of the slag storage tank is mainly adjusted, and the other key parameters are adjusted in an auxiliary mode. During implementation, the theoretical transfer speed of the slag storage tank can be determined according to the theoretical target value of the real-time slag quantity Q of the slag storage port, and the actual transfer speed is adjusted according to the theoretical transfer speed.
And when the actual slag output is not in the range value of the theoretical slag output, sequentially comparing the theoretical target value and the current value of each key parameter, and determining the weight and the adjustment priority of the key parameters.
For example, when the real-time slag quantity Q of the slag storage port is smaller than the theoretical target value range, the slag entering quantity of the slag storage tank is considered to be insufficient, the forward slag supply (along the slag soil transmission path, from the outer surface of the vertical shaft to the direction of the heading machine cutterhead) is smaller than the set range, and the front slag supply parameter needs to be further judged. Firstly, judging the height H of the slag suction port, and when the height H is not in the theoretical target value range, giving 90% weight to the slag suction port, and dividing the rest 10% weight by other key parameters. For example, the height H of the slag suction port is judged to be not satisfied, the height H of the slag suction port is mainly adjusted, and the transfer speed of the slag storage tank, the pressure of the slag suction port and the air flow intensity of the slag collecting port are regulated in an auxiliary manner.
Table 1 shows key parameter analysis, and the normal range in table 1 is shown in the theoretical target value range, and only the slag tap height range and the slag tap pressure range are shown in table 1.
TABLE 1 schematic of key parameter analysis
In table 1, the determination of the slag suction port pressure range and the slag suction port height range can determine the slag suction port amount, and in either case, the slag suction port amount falls on one of the three of "small front end slag supply amount", "large front end slag supply amount", and "normal slag discharge".
Fig. 4 is a logic diagram of a method for controlling slag tapping in a shaft according to an embodiment of the present invention, as shown in fig. 4. In combination with the table 1,
When the front-end slag supply amount is judged to be large, slag is accumulated at the slag suction port, and the slag collection intensity of the slag collection port at the front end is too high, so that the slag collection is too fast, and the slag discharge of the slag suction port is slow. At this time, the slag tap gas flow intensity weight was given 100%, the other 0%. The method comprises the steps of judging that the gas flow pressure of a slag collecting port is overlarge, recalculating the gas flow pressure of the slag collecting port (even if the gas flow pressure of the slag collecting port is in an original calculation range, recalculating according to the latest judgment of the height H of the slag absorbing port and the pressure of the slag absorbing port, adjusting the judgment results of the height H of the slag absorbing port and the pressure of the slag absorbing port, and adjusting the gas flow intensity of the slag collecting port higher than the priority of the original calculation range of the gas flow pressure of the slag collecting port), and simultaneously assisting in adjusting the transfer speed of a slag storage tank and the height of the slag absorbing port. When the front-end slag supply amount is judged to be small, the front-end slag collection is considered to be slower, namely the slag collecting port airflow pressure is judged to be too small, the slag collecting port airflow pressure is recalculated (even if the slag collecting port airflow pressure is in the original calculation range, the recalculation is performed according to the latest judgment of the slag suction port height H and the slag suction port pressure, the slag suction port height H and the slag suction port pressure judgment result are adjusted and are higher than the original calculation range priority of the slag collecting port airflow pressure), the slag suction port pressure is adjusted, and meanwhile, the transfer speed of the slag storage tank and the slag suction port height are adjusted in an auxiliary mode. Wherein, the weight value with high priority is large.
When all adjustable key parameters are adjusted, if the actual slag discharge amount is still not in the range value of the theoretical slag discharge amount, the capacity of the fan (11) can be determined to be insufficient, and the operation parameters of the fan, such as the fan frequency, are adjusted.
In summary, the embodiment of the invention realizes the full-automatic control and adjustment of the pneumatic conveying system according to the set tunneling speed under the working condition of the vertical shaft by the self-adaptive coupling automatic control of each key parameter, realizes the effects of 'how much to excavate in front and how much to slag to discharge in back' and 'how much to need to regulate how much to forcefully', ensures that the real-time slag discharge quantity is more stable, effectively avoids the condition of too much negligence in slag discharge, further improves the energy conservation and high efficiency of the system, saves the construction cost and improves the construction efficiency.
