[0055] Embodiment 1

[0056] Figs. 1-3This application provides an anti-entanglement and iron removal system for a hazardous waste incineration slag discharge machine. The system, applied to the slag discharge machine, mainly comprises four modules: an entanglement detection module, an entanglement removal module, a drive control module, and a safety protection module. The entanglement detection module detects the entanglement on the rotating shaft 1 of the slag discharge machine. The safety protection module receives and analyzes the information detected by the entanglement detection module. When the analysis indicates that entanglement 2 on the rotating shaft 1 exceeds a threshold, it sends a signal to control the drive control module. The drive control module, connected to the slag discharge machine, coordinates the rotation speed of the rotating shaft 1. Then, the entanglement removal module cleans the entanglement 2 from the rotating shaft 1. Through the coordinated operation of these four modules, this application achieves real-time online cleaning operations, completely solving the problem of equipment jamming caused by flexible metal entanglement, reducing unplanned downtime, ensuring continuous operation of the incineration line, and completely avoiding the risk of personnel entering a high-temperature, toxic environment.

[0057] In this embodiment, the winding detection module includes a vision sensor 3, which is a high-temperature resistant vision sensor 3. It can maintain the lens temperature ≤60°C through a compressed air cooling system. The vision sensor 3 in this application can identify the wire winding state on the surface of the slag machine shaft 1 in real time, and transmit the identified information to the safety protection module for subsequent operations.

[0058] In this embodiment, the winding and cutting module includes two sets of hydraulic drive components, which are symmetrically arranged on both sides of the rotating shaft 1. In order to better explain the hydraulic drive components, the hydraulic drive components on one side will be described in the following description, and the other hydraulic drive components can be symmetrically arranged.

[0059] A cutter head 7 is provided on the hydraulic drive assembly, which can drive the cutter head 7 to cut and clean the entangled material 2 on the rotating shaft 1.

[0060] To achieve better driving effect, in this application, the hydraulic drive assembly includes a cutting board 6, an X-axis and a Y-axis, wherein the X-axis is fixedly connected to the slag discharge machine (of course, in actual operation, the X-axis can also be fixedly set near the slag discharge machine, as long as the X-axis and the slag discharge machine are fixed to each other), the angle between the X-axis and the Y-axis is 90 degrees, one end of the Y-axis is set on the X-axis, and the other end is connected to the cutter head 7 through the flange 9.

[0061] Meanwhile, in order to ensure that the cutter disc 7 will not damage the rotating shaft 1 when cleaning the winding object 2, the cutting board 6 is fixedly connected with the Y-axis, and the cutting board 6 is parallel to the rotating shaft 1, and the distance between the cutting board 6 and the rotating shaft 1 is greater than or equal to 2 mm. In this way, when the cutter disc 7 is cleaning, because there is a gap between the winding object 2 and the rotating shaft 1, the cutting board 6 enters the gap, and the cutter disc 7 shears the winding object 2 on the cutting board 6, avoiding direct contact between the cutter disc 7 and the rotating shaft 1, and increasing the safety performance in use.

[0062] As can be seen from the above, the cutter disc 7 includes a first state away from the rotating shaft 1 and a second state for shearing and cleaning the winding object 2 on the rotating shaft 1 on the cutting board 6.

[0063] In order to ensure that the cutter disc 7 can smoothly switch between the first state and the second state, an X-axis hydraulic cylinder 5 is arranged on the X-axis, and a Y-axis hydraulic cylinder 4 is arranged on the Y-axis, wherein the X-axis hydraulic cylinder 5 drives the Y-axis to drive the cutter disc 7 to move axially along the rotating shaft 1, and the Y-axis hydraulic cylinder 4 drives the cutter disc 7 to move along the direction of the rotating shaft 1, that is, the X-axis hydraulic cylinder 5 moves the cutter disc 7 to the position where the rotating shaft 1 needs to be sheared and cleaned, and the Y-axis hydraulic cylinder 4 moves the cutter disc 7 to the direction of the rotating shaft 1 to realize the action of shearing and cleaning. Through the cooperation of the X-axis hydraulic cylinder 5 and the Y-axis hydraulic cylinder 4, the cutter disc 7 is switched from the first state to the second state.

[0064] In order to ensure that the movement of the cutter disc 7 will not affect the movement of the rotating shaft 1, in this embodiment, the winding cutting module further comprises a limit stop and a displacement sensor 11, wherein the limit stop is arranged on the cutting board 6, and the displacement sensor 11 is arranged on the Y-axis hydraulic cylinder 4 (of course, in actual operation, the displacement sensor 11 and the limit stop can also be arranged on the nearby wall), and is in communication with the safety protection module, wherein the limit stop is a precision limit stop, and the limit stop cooperates with the displacement sensor 11 to realize real-time regulation and control of the movement of the cutter disc 7 driven by the Y-axis hydraulic cylinder 4, preventing overcutting from damaging the rotating shaft 1. Specifically, the maximum output pressure of the Y-axis hydraulic cylinder 4 is 12 MPa, and the resolution of the displacement sensor 11 is 0.1 mm, ensuring that the single feeding amount of the Y-axis hydraulic cylinder 4 is accurate to 0.05 mm.

[0065] Of course, in actual operation, a displacement sensor can also be installed on the X-axis hydraulic rod 5 to detect the displacement of the cutter disc and the X-axis.

[0066] In order to better clean the winding object 2, electromagnets 8 are uniformly arranged around the cutter disc 7 to form an electromagnet array. When the cutter disc 7 cuts the winding object 2, the electromagnets 8 are energized to adsorb and clean the winding object 2 (the adsorption force after energization is greater than or equal to 180 N). When the cleaning is completed, the Y-axis hydraulic cylinder 4 drives the cutter disc 7 to return to the initial position, and the electromagnets 8 are de-energized to release the adsorbed winding object 2 to the collection box.

[0067] In the embodiment, the sum of the axial movement distances of the two X-axes driving the cutter head 7 along the rotation shaft 1 is equal to the length of the rotation shaft 1, and the positioning accuracy is ±0.3 mm.

[0068] In order to further strengthen the protection of the rotation shaft 1, in the embodiment, the safety protection module includes a force sensor 10, a PLC controller, and an audible and light alarm:

[0069] The force sensor 10 can be arranged on the cutter head 7 or the cutting board 6, and is used for detecting the radial pressure of the Y-axis of the cutter head 7. The PLC controller receives signals of the visual sensor 3, the position limiter, and the displacement sensor 11, and controls the operation of the X-axis hydraulic cylinder 5 and the Y-axis hydraulic cylinder 4 based on the received signals. When the operation of the cutter head 7 exceeds the limit in the received signals, the operation of the cutter head 7 is limited, and an alarm is sent through the audible and light alarm.

[0070] In the embodiment, the driving control module is interlocked with a slagging machine control system on the slagging machine, and the rotation speed of the rotation shaft 1 can be reduced.

[0071] In the embodiment, the diameter of the iron wire cut by the cutter head 7 is less than or equal to 3 mm, so that the running path of the cutter head 7 is less than or equal to 3 mm after the cutter head 7 contacts the iron wire, and the maximum radial cutting amount of the cutter head 7 is less than or equal to 3 mm.

[0072] In the embodiment, the winding cutting module further includes a servo proportional valve, which receives a displacement instruction generated by the PLC controller, accurately controls the X-axis movement distance, and controls the Y-axis feeding speed to be 0.1-5 mm / s.

[0073] In the embodiment, the operation safety limit is that the minimum distance between the cutting board 6 and the surface of the rotation shaft 1 is greater than or equal to 2 mm.

[0074] The shear depth limit is that the maximum radial cutting amount is less than or equal to 3 mm.

[0075] The emergency retreat limit is that when the position limiter detects that the cutter head 7 runs to the end of the stroke or exceeds the cutting range, the cutter head 7 retreats from the cutting board 6 by more than 20 mm within 0.5 s.

[0076] In order to further strengthen the understanding of the present application, the embodiment also provides an anti-winding iron removal method of the anti-winding iron removal system for the hazardous waste incineration slagging machine, which is suitable for the anti-winding iron removal system and includes the following steps:

[0078] 2、When the PLC controller detects that the winding condition exceeds the threshold value, a Y-axis radial feed instruction is generated, the PLC controller controls the drive control module to interlock with the control system of the slag extractor, reduces the rotating speed of the rotating shaft 1, and the PLC module controls the electromagnet 8 to be energized 0.5 seconds in advance to generate a magnetic force and activate the adsorption function;

[0079] 3、The PLC controller drives the X-axis hydraulic cylinder 5 to move, and drives the cutter head 7 to move along the rotating shaft 1 in the axial direction until the cutter head 7 and the cutting board 6 are transported to the position where the winding object 2 exists;

[0080] 4、The PLC controller drives the Y-axis hydraulic cylinder 4 to move, and drives the cutter head 7 to move towards the rotating shaft 1 at a speed of 0.5 mm / s, and the one-way cutting depth is less than or equal to 4 mm (1.5 times the diameter of the winding object 2), and the cutting board 6 cuts the winding object 2 on the rotating shaft 1 (ensuring that the distance between the cutting board 6 and the rotating shaft 1 is greater than or equal to 2 mm), and the electromagnet 8 adsorbs and cleans the cut winding object 2, and the PLC controller controls the Y-axis feed amount according to the position feedback of the limit switch and the displacement sensor 11 until the cutting operation is completed;

[0081] 5、After the cutting operation is completed, the PLC controller controls the Y-axis hydraulic cylinder 4 to reset to the initial position, the electromagnet 8 is de-energized, and the adsorbed winding object 2 falls into the collection box;

[0082] 6、The PLC controller drives the X-axis hydraulic cylinder 5 to continue to move the cutter head 7 along the rotating shaft 1 in the axial direction, and the movement distance is equal to the effective cutting width of the cutter head 7 minus 20 mm, and the above steps 2-5 are repeated until the winding object 2 on the rotating shaft 1 is cleaned, the PLC control X-axis driver is reset, the collection box is cleaned, the drive control module is disengaged, and the rotating shaft 1 resumes operation.

[0083] 7、When the PLC controller detects that the movement of the cutter head 7 exceeds the limit according to the data transmitted by the displacement sensor 11 and the force sensor 10 during operation, an alarm is issued:

[0084] Primary trigger: when the displacement sensor 11 detects that the displacement of the cutter head 7 exceeds the operation safety limit, the alarm starts to flash a warning in the field;

[0085] Secondary trigger: when the force sensor 10 detects that the Y-axis radial pressure of the cutter head 7 exceeds the threshold value for 2 seconds, an equipment abnormality code is sent;

[0086] Emergency trigger: when the limit switch is activated, the alarm switches to a high-frequency buzzing mode, and a burnout line load reduction operation instruction is triggered.

[0087] Wherein: the operation safety limit is that the minimum distance between the cutting board 6 and the surface of the rotating shaft 1 is greater than or equal to 2 mm;

[0088] The threshold value of the Y-axis radial pressure is 12 MPa.

[0091] 2. The present application drives the utility knife disc 7 from the first state to the second state by using the X-axis hydraulic cylinder 5 and the Y-axis hydraulic cylinder 4, which can not affect the normal operation of the rotating shaft 1 when the winding object 2 does not need to be cleaned, and can comprehensively clean the rotating shaft 1, thereby avoiding the phenomenon that the rotating shaft 1 is stuck by the winding object 2 due to incomplete cleaning.

[0092] 3. The present application cooperates the PLC controller with the visual sensor 3, the pressure sensor 10 and the force sensor 10 to precisely control the movement of the utility knife disc 7, so that the winding object 2 can be accurately cut during the movement of the utility knife disc 7, and the utility knife disc 7 can not damage the rotating shaft 1, thereby affecting the normal operation of the rotating shaft 1.

[0093] 4. The present application classifies the displacement of the utility knife disc 7 and the Y-axis radial pressure, starts different alarm levels, notifies the operator as soon as possible after the movement of the utility knife disc 7 exceeds the limit, and rectifies according to different alarm levels, thereby reducing the rectification time to a certain extent, improving the rectification efficiency, and ensuring the smooth progress of the cleaning work of the winding object 2.
