Description

Technical Field

[0001] The invention relates to the field of power plant equipment, and in particular to a slag scoop machine steering switching device. Background Art

[0002] The slag scraper is an important equipment in coal-fired power plants. It can continuously transport the coal slag after combustion in the boiler to the slag bin. However, during the operation of the device, it is inevitable that large volumes of slag or other foreign matter will fall into the collection tank of the slag scraper. In particular, some device structures will be damaged or fall after continuous operation in a high-temperature environment for a long time. These large foreign matter will seriously affect the overall operating efficiency of the slag scraper. If such foreign matter is stuck in the scraper chain assembly, it will seriously affect the operation of the device and bring great difficulties to subsequent maintenance. The relevant solutions currently on the market often cooperate with the steering structure to control the operation of the scraper chain assembly, so as to adjust the position of the foreign matter and ensure the normal operation of the device and facilitate maintenance. However, this method still requires relatively fine control, which often wastes a lot of manpower and energy, and is still relatively inconvenient in the actual operation process.

The sorting fork 6 is used to intercept larger foreign objects in the coal slag. The control box 12 is located on one side of the slag remover 1 and below the inclined rising section trough. The interior of the control box 12 includes a control valve 16 and a hydraulic motor 19. The control valve 16 is located on the inner side of the control box 12. The control valve 16 has a hydraulic circuit interface 15 below it. The hydraulic motor 19 is located above the control valve 16. The hydraulic motor 19 has a transmission sprocket structure 13 on one side close to the slag remover 1, which is transmission-connected to the scraper chain assembly of the slag remover 1.

A vibration sensor is installed on one side of the slag scoop machine 1, and one end of the vibration sensor has a line connected to the control box 12. The vibration sensor is used to detect the operating status of the slag scoop machine 1. When a strong impact produces vibration, the sensor will release an electrical signal to stop the hydraulic motor 19.

[0019] The maximum width of the sorting fork frame 6 is less than the width between the guard plates on both sides of the slag scoop 1, and the length of the sorting fork frame 6 is less than the height from the rotating motor 7 to the scraper chain assembly. A camera 8 is provided at the upper end of the side bracket 4, and the camera 8 is arranged toward one side of the sorting fork frame 6. The camera 8 is used to obtain the image of the debris in the slag scoop 1. There are two side brackets 4 on one side, and a collecting bucket 5 is provided between the side brackets 4. The inner side of the side bracket 4 near the collecting bucket 5 is provided with a slide rail, and the collecting bucket 5 is slidably connected to the side bracket 4 through the slide rail. The lower end of the collecting bucket 5 is provided with a square steel pad, and the square steel pad is used for fixed connection and transportation by a forklift. The slide rail on one side of the screw motor 9 extends from the side bracket 4 to the top of the collecting bucket 5, and the collecting bucket 5 is used to collect the foreign matter separated by the sorting fork frame 6. The sorting fork frame 6 can be adjusted according to the use requirements or the model of the slag scoop 1. The sorting fork frame 6 is composed of a plurality of steel plates with arcs. The sorting fork frame 6 can be rotated along the axis direction of the rotating motor 7 to take out the foreign matter for temporary storage.

[0020] The side of the sorting fork frame 6 close to the discharge port 11 is provided with a material-forming guard plate 21, which is located on the inner side of the guard plate of the inclined ascending section trough body, and the shape of the material-forming guard plate 21 is a right-angle plate, and the side of the material-forming guard plate 21 close to the guard plate is provided with a mounting plate 10 and a bolt for detachable connection, and the side of the material-forming guard plate 21 close to the sorting fork frame 6 is provided with a side guide plate, and the side guide plate is a square plate, and the inner side of the support foot of the material-forming guard plate 21 is provided with a triangular guard plate for shaping the slag material for convenient transportation. The bolts on the inner side of the mounting plate 10 can adjust the installation length according to the use requirements, thereby adjusting the installation position of the material-forming guard plate 21.

[0021] The control box 12 has a heat dissipation port 14 on one side, and a heat dissipation fan 17 is provided on one side of the heat dissipation port 14. The heat dissipation fan 17 is located inside the control box 12 and above the control valve 16. The heat dissipation fan 17 is used to discharge the heat inside the control box 12 to the outside. The control box 12 has a control panel on one side, and the control panel is located on the side of the heat dissipation port 14 away from the slag scooper 1. A control module 18 is provided on one side of the control panel. The control module 18 is located inside the control box 12. One side of the control module 18 has a line connected to the control valve 16, the hydraulic motor 19 and the plunger pump 20. The control valve 16 also includes an oil return filter, one end of which is connected to the hydraulic oil tank. The control valve 16 is used to control the operation of the plunger pump 20 and the hydraulic motor 19.

[0022] When in use, after the slag enters the slag scoop machine 1, it will be transported to the bottom of the sorting fork frame 6 by the scraper chain assembly. At this time, the sorting fork frame 6 is controlled by the rotating motor 7 to tilt the tip of the fork frame toward the slag. After intercepting foreign matter, the camera 8 will capture relevant image information, and then send an electrical signal to the control module 18. After obtaining the corresponding operating instructions, the rotating motor 7 will rotate to a horizontal angle, and then the screw motor 9 will drive the entire sorting fork frame 6 to move through the screw and the slide rail. When it moves to the top of the collecting bucket 5, the rotating motor 7 will rotate the sorting fork frame 6 again and make the foreign matter fall into the collecting bucket 5; the slag after the initial screening will be transported to the inclined rising section trough by the scraper chain assembly. At this time, the whole material guard plate 21 will sort the shape of the stacked slag, so as to facilitate the slag to cooperate with the scraper chain assembly to be transported obliquely and discharged outward through the discharge port 11.

[0023] During the entire process, the operator can input corresponding control instructions to the control module 18 through the control panel. When the moving direction of the scraper chain assembly needs to be switched, the control module 18 will input a reversing instruction to the control valve 16 to change the delivery direction of the hydraulic oil tank plunger pump 20 and the hydraulic motor 19, thereby realizing the reverse operation of the scraper chain assembly.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
