[0002] When coking coal is blended in the coke oven of the coking industry, it is necessary to first determine the proportion of different grades of coking coal. The disk feeder is one of the most important equipment in the automatic coal blending link. The disk feeder is a mechanical equipment used for the supply of powder and granular materials, and is usually used to evenly and continuously supply granular materials to a production line or other processing equipment. It uses a rotating disk to provide materials, and cooperates with a deflector or an adjusting device to evenly convey materials to downstream equipment. The specific process of disk feeding is as follows: the materials in the batching bin are taken out by the rotation of the disk, and the materials fall on the belt weighing scale after passing through the baffle in front of the disk discharging port. The belt rotates, and the material quantity above the belt is measured when passing through the weighing point of the weighing scale. Subsequently, the measurement result is fed back to the disk feeder, and the control system compares the real-time measurement data of the weighing scale with the given ratio value, and judges whether to adjust the disk rotation speed according to the comparison result, with the aim of ensuring that the feeding quantity approaches the given ratio value through this system control method.

[0021] Embodiment 1

[0022] As Figure 1-2 shown, a disk feeder with an adjustable blanking point includes a frame 1, a cylindrical frame 4, a power device 2, a disk 3, and a blanking volute 12.

[0023] The cylindrical frame 4 is fixedly arranged above the frame 1, the power device 2 is installed on the frame 1, the disk 3 is arranged in the cylindrical frame 4 and connected to the transmission component of the power device 2, and the power device 2 drives the disk 3 to rotate. The power device 2 is a reduction motor, and the transmission component is a gear shaft component. The motor shaft of the reduction motor is connected in cooperation with a small gear, the bottom of the disk 3 is connected in cooperation with a large gear, the small gear and the large gear are meshed, and the bottom of the disk 3 is also connected to a slewing bearing.

[0024] A blanking volute 12 is arranged above the disk 3. The upper and lower ends of the blanking volute 12 are open, and a discharge port is arranged on the side of the bottom of the blanking volute 12. A flow rate adjusting component 13 is arranged at the discharge port. The flow rate adjusting component 13 is a prior art, which includes a worm and worm gear structure. The worm is connected to a handwheel, and a sector baffle is arranged on the worm. The worm is driven to rotate by the handwheel, thereby driving the sector baffle to rotate to adjust the opening size of the discharge port. The top of the blanking volute 12 is connected to a feed bin, and the materials in the feed bin are fed into the upper part of the disk 3 through the discharge port of the blanking volute 12. One side of the cylindrical frame 4 is communicated with a blanking chute 6. A guide scraper 14 is arranged at the communicating part of the cylindrical frame 4 and the blanking chute 6, and the angle of the guide scraper 14 can also be adjusted to transfer the materials on the disk 3 to the blanking chute 6 and play a guiding role for the materials.

[0025] The blanking chute 6 is a square frame with open upper and lower ends. A blanking port is arranged at the bottom of the blanking chute 6, and a belt conveyor 5 is arranged below the blanking port of the blanking chute 6. A linear driving device 7 is installed on one side of the blanking chute 6. The linear driving device 7 is connected to one end of a connecting rod 10, and the other end of the connecting rod 10 is connected to one end of an adjusting baffle 9 through a hinge seat 11, and the other end of the adjusting baffle 9 is placed in the blanking chute 6. Specifically, an opening is arranged on the outer side of the blanking chute 6, and the other end of the adjusting baffle 9 passes through the opening and is inclined and placed inside the blanking chute 6.

[0026] Specifically, the linear drive device 7 can be a hydraulic cylinder, a pneumatic cylinder, etc., and preferably an electro-hydraulic push rod. The piston rod 8 of the electro-hydraulic push rod is hinged to one end of the connecting rod 10. The electro-hydraulic push rod is a prior art, which mainly consists of a motor, a pump, an oil cylinder, a control system, a heat dissipation system, etc. The motor serves as a power source to drive the pump to rotate. The pump sucks in hydraulic oil and pressurizes it and then transports it to the oil cylinder. There are two chambers in the oil cylinder, one is the oil chamber for pushing the piston, and the other is the oil chamber for retracting the piston. By controlling the inflow and outflow of the hydraulic oil in the oil cylinder, the reciprocating movement of the piston can be realized, so as to drive the load to perform corresponding actions. The linear drive device 7 drives the connecting rod 10 to move, and the connecting rod 10 drives the adjusting baffle 9 to rotate along the hinge seat 11. By adjusting the inclination of the adjusting baffle 9, the position of the center line of the feeding port, that is, the position of the discharging point, is adjusted to be consistent with the center line of the belt conveyor 5.

[0027] The cylinder block of the oil cylinder of the electro-hydraulic push rod is installed on the cylindrical frame 4 through the fixed ear seat 16. The cylinder block of the electro-hydraulic push rod is hinged to the fixed ear seat 16, and the fixed ear seat 16 is arranged on the outside of the feeding chute 6.

[0028] In addition, the length of the adjusting baffle 9 is adjustable to meet different working conditions. The adjusting baffle 9 is an arc-shaped plate, which reduces the erosion and wear of the material on it and improves the service life. The electro-hydraulic push rod is electrically connected to the PLC control system 15, and the lifting of the electro-hydraulic push rod is automatically controlled through the PLC control system 15, so as to automatically control the angle of the adjusting baffle 9.

[0029] Embodiment 2

[0030] This embodiment is based on Embodiment 1. The difference from Embodiment 1 is that, further, two electro-hydraulic push rods are provided. The two electro-hydraulic push rods are respectively arranged at both ends of the feeding chute 6 in the length direction. The piston rods 8 of the two electro-hydraulic push rods are respectively hinged to one end of the two connecting rods 10.

[0031] Two hinge seats 11 are provided. The two hinge seats 11 are respectively arranged at both ends of the feeding chute 6 in the length direction. The other ends of the two connecting rods 10 are fixedly connected to both ends of the rotating shaft 17 of the hinge seat 11. One side edge in the length direction of the adjusting baffle 9 is fixedly connected to the side edge of the rotating shaft 17.

[0032] Principle of use:

[0033] The pulverized coal material in the silo falls into the disk 3 from the opening below the blanking volute 12. As the disk 3 rotates, the pulverized coal flows out from the discharge port on the side of the blanking volute 12. The angle of the sector baffle of the flow regulating assembly 13 is adjusted according to the coal blending speed. As the disk 3 rotates, the pulverized coal enters the blanking chute 6 along the guiding scraper. The pulverized coal falls onto the belt of the belt conveyor 5 from the blanking port of the blanking chute 6 and is transported to the next process by the belt conveyor 5.

[0034] During normal operation, the regulating baffle 9 is arranged at the lower end of the blanking chute 6 and is biased to the right. When the midline of the blanking port is not aligned with the midline of the belt conveyor 5, the discharge point is not on the midline in the width direction of the belt conveyor 5. If feeding continues, due to the offset of the pulverized coal material, the belt of the belt conveyor 5 will deviate, affecting the accuracy of automatic coal blending and thus reducing the quality of the coke produced in the coke oven. At this time, the two electro-hydraulic push rods at both ends are simultaneously activated through the PLC control system 15, and the angle of the regulating baffle 9 is set by calculation. The piston rod 8 of the electro-hydraulic push rod moves downward by a certain distance, driving the connecting rod 10 to rotate along the hinge seat 11, thereby driving the rotating shaft 17 of the hinge seat 11 to rotate. The rotating shaft 17 drives the regulating baffle 9 to rotate, making the lower end of the regulating baffle 9 tilt upward to the left. The pulverized coal material first falls on the regulating baffle 9, changing the actual width of the blanking port, and then changing the actual midline of the blanking port, and then falling on the belt conveyor 5, so that the discharge point of the blanking port can be adjusted.
