Description

Technical Field

[0001] The invention relates to the technical field of material loading and unloading, and in particular to an automatic slag loading control system and method. Background Art

[0002] The ash and slag produced by thermal power plants have certain utilization value. For example, they can be used to produce cement and hollow bricks. The loading process has a low degree of automation and needs to rely on the control room operator to control the loading software. The operator also needs to command the ground personnel through the walkie-talkie, and the ground personnel then command the truck driver to move the vehicle to complete the loading.

[0003] In the existing slag loading process of power plants, the ash and slag produced by coal combustion enter the slag bin from the top of the slag bin, and then the materials are discharged into the slag-loading transport vehicle at a specific speed through the unloading device at the bottom of the slag bin. The device that realizes this function is a dry ash bulk loader. The operation of the dry ash bulk loader requires an induced draft fan to absorb dust-containing gas from the inside of the telescopic cylinder to keep the inside of the dry ash bulk loader in a negative pressure state, absorb the dust-containing gas, and prevent ash from emitting. Conventional dust collectors use bag filtration, which has a slow filtration speed, uses a large number of bags, and is large in size. The bulk loader has a low degree of automation and is mainly operated manually. In addition, the bucket of the dump truck is open. In order to solve the waste of transportation space caused by a single landing point, the position of the transport vehicle needs to be adjusted.

[0017] In summary, the present invention has the following beneficial technical effects: The present invention has the following beneficial technical effects: 1. The present invention proposes an automatic slag loading control system and method, which improves the automation of slag loading. The traditional slag loading process of power plants relies on the control room operator to control the loading software, and multiple people are required to cooperate to direct the movement of vehicles.

[0025] The slag loading automatic control system also includes: The second detection device 104 is arranged at the lower side of the support platform 101 and connected to the control device, and is used to detect the position information of the bottom plate of the transport vehicle 2 and send the position information of the bottom plate of the transport vehicle 2 to the control device; The control device is also used to calculate the bucket depth information based on the bucket bottom plate position information and the bucket edge position information, and send control instructions to the mobile device to control the discharge port of the bulk loader 4 to move downward to the bucket bottom plate and upward to the bucket depth distance.

[0026] The first detection device 103 and the second detection device 104 are infrared rangefinders.

[0027] Reference Figure 2 , the moving device includes a walking mechanism 3 and a driving mechanism 5 arranged on the upper side of the support platform 101; The control device is used to send a control instruction to the traveling mechanism 3 when the position information of the bottom plate of the bucket sent by the second detection device 104 is not received; The walking mechanism 3 includes a guide rail 301 arranged on the upper side of the support platform 101, a mobile vehicle 303 arranged on the guide rail 301, the dry slag bin 1 is arranged on the mobile vehicle 303, and a support frame 302 is provided between the dry slag bin 1 and the mobile vehicle 303. The walking mechanism 3 is used to drive the mobile vehicle 303 to walk along the guide rail 301 according to the received control command; The control device is used to calculate the depth information of the bucket when receiving the bucket bottom plate position information sent by the second detection device 104, and send a control instruction to the driving mechanism 5; The driving mechanism 5 is used to drive the discharge port of the bulk loader 4 to move downward according to the bucket bottom plate position information based on the received control instructions, and to drive the discharge port of the bulk loader 4 to move upward according to the bucket depth information by the depth distance calculated by the control device.

[0028] The guide rail 301 of the traveling mechanism 3 ensures that the dry slag bin 1 and the bulk loader 4 can move horizontally on the support platform 101. The mobile vehicle 303 is driven by a variable frequency motor to travel on the guide rail 301. It can bear the weight of the dry slag bin 1 and related equipment and achieve smooth and efficient displacement. When faced with transport vehicles 2 of different sizes and parking positions, the traveling mechanism 3 can quickly move the bulk loader 4 to the top of the appropriate unloading position, effectively expanding the coverage of the slag loading operation and improving the adaptability of the slag loading system to different working conditions. Moreover, due to the use of a variable frequency motor drive, position adjustment can be achieved according to the instructions of the control device, and a smooth transition can be achieved when starting and stopping, reducing the mechanical impact of the equipment, extending the service life of the equipment, and also facilitating the precise positioning of the bulk loader 4.

[0029] The mobile vehicle 303 is driven by a variable frequency motor, and the control device includes a PLC controller 703. The variable frequency motor is electrically connected to the control output end of the PLC controller 703. A proximity switch 304 is provided on the mobile vehicle 303. A plurality of induction plates 305 are evenly provided on the support platform 101 along the direction of the guide rail 301. The control device controls the induction plates 305 in the corresponding areas projected on the active area to be energized, thereby limiting the mobile vehicle 303.

[0030] The proximity switch 304 is a magnetic element, and the induction plate 305 has a built-in Hall sensor.

[0031] The discharge port at the bottom of the dry slag bin 1 is provided with an electric gate valve, and the electric gate valve is electrically connected to the PLC controller 703.

[0032] Reference Figure 1 , taking the travel direction of the transport vehicle 2 as the X-axis and the vertical direction as the Y-axis, a spatial rectangular coordinate system is constructed, wherein the coordinate of A is (x1, y1), the coordinate of B is (x2, y2), the coordinate of C is (x3, y3), and the coordinate of D is (x4, y4). The coordinates of point A, point B, and point C are detected by the first detection device 103. When the coordinate y1 is greater than y4 and y2 is close to y1, the first detection device 103 detects successfully and obtains the edge position information of the bucket. The coordinate of point D is detected by the second detection device 104. The depth of the bucket is y1-y4, and the position of the bottom plate of the bucket is y4. The first detection device 103 and the second detection device 104 are infrared detectors.

[0033] The PLC controller 703 calculates the target position coordinates to which the bulk loader 4 needs to move based on the position information of the edge of the bucket of the transport vehicle 2 detected by the first detection device 103. Then, the PLC controller 703 sends a control signal to the variable frequency motor to control the speed and direction of the variable frequency motor. For example, if it is calculated that the bulk loader 4 needs to move 2 meters to the right to reach the unloading area, the PLC controller 703 will output a corresponding pulse signal to the variable frequency motor driver to make the variable frequency motor rotate forward and drive the mobile vehicle 303 to move to the right along the guide rail 301 at a suitable speed. At the same time, the proximity switch 304 on the mobile vehicle 303 cooperates with the induction plate 305 on the support platform 101 to realize the limit function. When the proximity switch 304 approaches the energized induction plate 305, the proximity switch 304 will send a signal to the PLC controller 703, and the PLC controller 703 will stop the operation of the variable frequency motor according to this signal to ensure that the mobile vehicle 303 reaches the limit position for unloading.

[0034] Reference Figure 3 and Figure 4The driving mechanism 5 is arranged on the support frame 302, and the driving mechanism 5 includes an outer steel wire rope 501, a stepper motor 502, a steel wire disc 503 connected to the driving shaft of the stepper motor 502, and a fixed pulley 504 is also arranged on the support frame 302. The bulk loader 4 includes a base 401, a fixed inner cylinder 402 bolted to the lower side of the base 401, a plurality of conical movable inner cylinders 403 connected in series by an inner steel wire rope 505, and a telescopic outer cylinder 404 sleeved on the outer side of the movable inner cylinder 403. The uppermost end of the telescopic outer cylinder 404 is fixed to the lower side of the base 401, and a discharging head 405 is formed at the lowermost end of the telescopic outer cylinder 404. The discharging head 405 is fixedly connected to the movable inner cylinder 403 at the lowermost end. One end of the outer steel wire rope 501 is wound around the steel wire drum 503, and the other end passes around the fixed pulley 504 and passes through the support frame 302 to be fixed to the lower end of the telescopic outer cylinder 404. A limiting ring 406 is provided on the side wall of the telescopic outer cylinder 404, and the outer steel wire rope 501 is passed through the limiting ring 406.

[0035] Reference Figure 6 A sandwich space 601 is formed between the telescopic outer cylinder 404 and the movable inner cylinder 403. The bulk loader 4 also includes an ash removal mechanism 6, which is arranged on the upper side of the base 401. The ash removal mechanism 6 includes a disposal chamber 602, which is communicated with the sandwich space 601. A discharge pipe 603 connected to the fixed inner cylinder 402 is provided in the middle of the disposal chamber 602. An induced draft pipe 604 that passes through the inside and outside of the disposal chamber 602 is provided on the disposal chamber 602. The induced draft pipe 604 is connected to an induced draft fan 605 at one end outside the disposal chamber 602, and is connected to a filter 606 at the other end inside the disposal chamber 602. The filter 606 is spirally coiled on the discharge pipe 603.

[0036] The driving mechanism 5 is mainly responsible for the vertical movement of the discharge port of the bulk loader 4. The stepper motor 502 is used as the driving source. Through the transmission of the wire disc 503 and the outer wire rope 501, it can accurately control the lifting and lowering of the telescopic outer cylinder 404. During the slag loading process, it can accurately position the discharge port to a position close to the bottom plate of the bucket according to the depth information of the bucket to avoid the generation of slag dust when the slag falls. For example, when the depth of the bucket is 1.5 meters, the driving mechanism 5 can accurately lower the discharge port to a height of about 10 cm from the bottom plate of the bucket to start unloading, and during the slag loading process, the discharge head 405 will gradually move up until it reaches the height of the bucket and stops unloading. The upward movement speed is the set speed, which meets the matching of the upward movement and the unloading amount, and ensures that the slag is evenly loaded and does not overflow the bucket. The control device controls the electric gate valve according to the different stages of the slag loading operation and the system operation status. The gate valve is opened at a preset angle to control the unloading flow. The design of the driving mechanism 5 makes the bulk loader 4 move stably and reliably in the vertical direction, can meet the slag loading requirements of buckets of different depths, and improves the quality and efficiency of slag loading.

[0037] When the control device receives the bucket bottom plate position information sent by the second detection device 104, it first calculates the bucket depth information. Then, the PLC controller 703 generates a pulse signal based on these data and sends it to the stepper motor 502 driver to control the number of steps and direction of rotation of the stepper motor 502. For example, if the bucket depth is 1.5 meters, the discharge port needs to be lowered to 10 centimeters from the bucket bottom plate. The PLC controller 703 will calculate the required number of pulses based on the pre-set parameters such as the step angle of the stepper motor 502, and control the stepper motor 502 to reverse, so that the wire drum 503 releases the outer wire rope 501, and the outer wire rope 501 bypasses the fixed pulley 504 to pull the lower end of the telescopic outer cylinder 404, so that the discharge port is lowered. During the slag loading process, when the discharge port needs to be raised, the PLC controller 703 calculates the number of pulses corresponding to the required lifting height based on the bucket depth and the slag loading progress information, controls the stepper motor 502 to rotate forward, retracts the outer wire rope 501, and raises the discharge port to a corresponding height, thereby achieving precise control of the vertical position of the discharge port of the bulk loader 4.

[0038] Reference Figure 3 and Figure 5 The filter 606 is also provided with a back-blowing mechanism 7, which includes a back-blowing pipe 701, a solenoid valve 702 and a controller 703 for controlling the solenoid valve 702. One end of the back-blowing pipe 701 extends into the filter 606, and the other end of the back-blowing pipe 701 is connected to compressed gas through the solenoid valve 702.

[0039] The treatment chamber 602 is connected with the interlayer space 601 between the telescopic outer cylinder 404 and the movable inner cylinder 403. Under the action of the induced draft fan 605, the interlayer space 601 forms a negative pressure, and the dusty air generated when loading slag is sucked into the treatment chamber 602. The filter 606 spirally arranged on the discharge pipe 603 can increase the contact area between the dust and the filter medium and improve the filtering efficiency. The control device controls the induced draft fan 605 to start. The negative pressure generated by the operation of the induced draft fan 605 causes the dusty air to enter the treatment chamber 602 from the interlayer space 601. When the unloading of a vehicle is completed, the controller 703 controls the solenoid valve 702 of the back-blowing mechanism 7 to open, and the compressed gas enters the filter 606 through the back-blowing pipe 701, and the dust on the filter 606 is blown off with a larger airflow, so that the filter 606 restores the filtering performance.

Get the position information of the edge of the bucket and the bottom of the bucket of the transport vehicle 2; S2. Calculate the active unloading area of ​​the bulk loader 4 according to the position information of the edge of the bucket, and energize the induction plate 305 corresponding to the projection of the active area according to the active unloading area, and control the walking mechanism 3 to move the bulk loader 4 to the position of the induction plate 305 according to the guide rail 301; S3.

Discharging and opening the induced draft fan 605, through the ash removal mechanism 6 for unloading ash removal, the bulk loader 4 material outlet moves upward car 303 bucket depth distance after closing the electric gate valve, and stop the ash removal mechanism 6 for ash removal; S5. The traveling mechanism 3 drives the bulk loader 4 to continue to move along the guide rail 301 to the position of the next induction plate 305 to carry out the next round of unloading until the last round of unloading is completed.

[0041] S6. A control instruction is sent to the controller 703 of the back-blowing mechanism 7 through the control device. The back-blowing mechanism 7 receives the control instruction and opens the solenoid valve 702 to allow compressed air to enter the filter 606, so that the ash on the outer surface of the filter 606 and the interlayer space 601 falls into the truck bucket.
