Description

Technical Field

[0001] This invention relates to the field of coal blending technology, and in particular to a coal blending device and method. Background Technology

[0002] Coal blending is an important preparation process for coal materials before coking or carbonization. In order to produce coke, power coal, and boiler coal that meet quality requirements, different types of raw coal are combined in appropriate proportions. Automatic coal blending devices are one type of coal blending equipment. They can automatically control the amount of each type of coal added according to a given value to ensure the accuracy and constantness of the blending ratio and the amount added.

[0003] During the coal blending process, different types of coal need to be placed in different blending bins of an automatic coal blending device. The coal falls by gravity. However, existing blending bins do not have unblocking components. Therefore, during the coal's fall, blockages may occur, affecting the normal use of the blending bin. Current methods involve manually pushing the coal with tools to achieve continuous falling, which is time-consuming and laborious. Meanwhile, some automatic coal blending devices are equipped with vibrating motors, but it cannot be guaranteed that the vibrating motors will vibrate the coal to fall 100%.

[0004] Therefore, it is necessary to provide a coal blending device and method to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a coal blending device and method.

[0006] This invention provides a coal blending device comprising an automatic coal blending device frame, coal blending bins, electromagnetic vibrating feeders, and a conveyor belt. Coal blending bins for holding coal are equidistantly installed on the top of the automatic coal blending device frame. Electromagnetic vibrating feeders for feeding coal are fixedly installed at the bottom of the coal blending bins. A conveyor belt for conveying coal is installed at the bottom of the automatic coal blending device frame corresponding to the position of the coal blending bins. The device also includes a pusher plate and a reciprocating pushing device. The pusher plate and the reciprocating pushing device are symmetrically mounted on the inner wall of the coal blending bins via pivot pins. A reciprocating pushing device for intermittent rotation of the pusher plate is fixedly installed in the middle of the coal blending bins. In use, different types of coal are placed in different coal blending bins. The electromagnetic vibrating feeders at different positions quantitatively discharge the coal, which is then mixed by the conveyor belt. Simultaneously, the operation of the reciprocating pushing device drives the reciprocating rotation of the pusher plate, thus pushing the coal inside the coal blending bins and preventing coal accumulation and non-discharge.

[0007] Preferably, the end of the pusher plate furthest from the coal blending bin is fitted against the inner wall of the coal blending bin. This prevents a large amount of coal from adhering to the position of the pusher plate in the coal blending bin.

[0008] Preferably, the reciprocating pushing device includes a control motor, a rotating plate, a connecting rod, a chute, a slider, a slide rod, and positioning holes. The control motor is bolted to both sides of the coal mixing bin. The rotating plate is fixedly mounted to the output end of the control motor. A connecting rod is eccentrically mounted on the side of the rotating plate away from the control motor via a pin. A chute is formed on one side of the pushing plate, and a slider is slidably mounted in the middle of the chute. A slide rod is rotatably mounted on one side of the slider via a pin. Positioning holes are formed on both sides of the coal mixing bin corresponding to the positions of the slide rods. The positioning holes are slidably connected to the slide rods. The end of the slide rod away from the slider is rotatably connected to the end of the connecting rod away from the rotating plate via a pin. In use, the control motor controls the rotation of the rotating plate. Through the connection of the connecting rod and the slide rod, the rotation of the pushing plate is achieved, thus pushing the coal inside the coal mixing bin and preventing coal from accumulating and failing to be discharged.

[0009] Preferably, the control motor is a geared motor, providing sufficient power for the rotation of the rotating plate.

[0010] Preferably, the two ends of the slider are inclined to prevent coal from accumulating at the top of the two ends of the slider and slipping off.

[0011] Preferably, the positioning hole and the slide rod slide in a tight fit. This ensures the stability of the slide rod sliding inside the positioning hole and prevents coal leakage in the middle of the positioning hole.

[0012] Preferably, the inner walls of both sides of the coal blending bin are symmetrically provided with mounting slots. A rotating rod is rotatably mounted on the coal blending bin at the position corresponding to the mounting slot. A baffle is fixedly mounted in the middle of the rotating rod, which is used to block the area below the baffle in the coal blending bin. Torsion springs are symmetrically sleeved at both ends of the rotating rod. One end of the torsion spring is fixedly connected to the inner wall of the corresponding mounting slot in the coal blending bin, and the other end of the torsion spring is fixedly connected to one end of the baffle. During the reciprocating rotation of the push plate, the top of the push plate will press against the baffle, causing the baffle to rotate. This can block the rotating push plate below the baffle, preventing a large amount of coal from appearing below the baffle and affecting the push plate's reset.

[0013] Preferably, this solution also includes a coal blending method, comprising the aforementioned coal blending device, including the following steps: S1. When the device is in use, different types of coal are placed in different coal mixing bins. The coal is quantitatively discharged by electromagnetic vibrating feeders at different positions and mixed by conveying through a conveyor belt. S2. When discharging coal, the rotating plate is controlled by the motor. The connecting rod drives the slide rod to slide back and forth inside the positioning hole. At the same time, the movement of the slide rod drives the push plate to rotate back and forth. Meanwhile, the slider slides inside the chute, thereby realizing the rotation of the push plate and pushing the coal inside the coal blending bin, preventing the coal from accumulating inside the coal blending bin and failing to be discharged. S3. During the reciprocating rotation of the push plate, the top of the push plate will press against the baffle, thereby causing the baffle to rotate. This will block the rotating push plate below the baffle and prevent a large amount of coal from appearing below the baffle and affecting the reset of the push plate. During the reset of the push plate during reciprocating rotation, the torsion spring will drive the baffle to rotate to one side of the push plate, thus achieving the reset of the baffle.

[0014] Compared with related technologies, the coal blending device and method provided by the present invention have the following beneficial effects: In use, this invention controls the rotation of a rotating plate by a motor during coal discharge. The connecting rod then drives a sliding rod to reciprocate within a positioning hole. Simultaneously, the movement of the sliding rod drives the reciprocating rotation of a push plate. Meanwhile, a slider slides within a groove, thus rotating the push plate and pushing the coal within the coal blending bin. This prevents coal from accumulating and failing to discharge within the bin. Compared to existing technologies, this invention completely solves the problem of coal accumulation and failure to discharge within the coal blending bin, and eliminates the need for manual pushing of the coal, saving manpower.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figures 1 to 6 A coal blending device includes an automatic coal blending device frame 1, a coal blending bin 2, an electromagnetic vibrating feeder 3, and a conveyor belt 4. The coal blending bin 2 for holding coal is installed at equal intervals on the top of the automatic coal blending device frame 1. The electromagnetic vibrating feeder 3 for feeding coal is fixedly installed at the bottom of the coal blending bin 2. The method of discharging coal from the coal blending bin 2 by the electromagnetic vibrating feeder 3 is the same as the working principle of discharging coal from the existing coal blending bin 2. The conveyor belt 4 for conveying coal is installed at the bottom of the automatic coal blending device frame 1 corresponding to the position of the coal blending bin 2. The method of mixing coal by the conveyor belt 4 is the same as the working principle of mixing coal by the existing coal blending. It also includes a pusher plate 5 and a reciprocating pusher device 6. The pusher plate 5 and the reciprocating pusher device 6 are symmetrically rotated on the inner wall of the coal blending bin 2 through a pivot pin. The reciprocating pusher device 6 for intermittent rotation of the pusher plate 5 is fixedly installed in the middle of the coal blending bin 2. When the device is in use, different types of coal are placed in different coal blending bins 2. The coal is quantitatively discharged by electromagnetic vibrating feeders 3 at different positions and mixed by conveying by conveyor belt 4. At the same time, the operation of reciprocating pushing device 6 drives the push plate 5 to reciprocate, thereby pushing the coal inside the coal blending bin 2 and preventing the coal from accumulating and not being discharged.

[0019] Please refer to the following: Figures 1 to 6 The end of the pusher plate 5 furthest from the coal blending bin 2 is fitted against the inner wall of the coal blending bin 2. This prevents a large amount of coal from sticking to the position of the pusher plate 5 in the coal blending bin 2.

[0020] Please refer to the following: Figures 1 to 6The reciprocating feeding device 6 includes a control motor 61, a rotating plate 62, a connecting rod 63, a chute 64, a slider 65, a slide rod 66, and a positioning hole 67. The control motor 61 is fixedly installed on both sides of the coal mixing bin 2 by bolts. The rotating plate 62 is fixedly installed at the output end of the control motor 61. The connecting rod 63 is eccentrically mounted on the side of the rotating plate 62 away from the control motor 61 by a shaft pin. A chute 64 is opened on one side of the push plate 5. A slider 65 is slidably installed in the middle of the chute 64. A slide rod 66 is rotatably mounted on one side of the slider 65 by a shaft pin. Positioning holes 67 are opened on both sides of the coal mixing bin 2 corresponding to the position of the slide rod 66. The positioning holes 67 are slidably connected to the slide rod 66. The end of the slide rod 66 away from the slider 65 is rotatably connected to the end of the connecting rod 63 away from the rotating plate 62 by a shaft pin. When the device is in use, the rotating plate 62 is controlled by the motor 61. The connecting rod 63 drives the slide rod 66 to slide back and forth inside the positioning hole 67. At the same time, the movement of the slide rod 66 drives the push plate 5 to rotate back and forth. Meanwhile, the slider 65 slides inside the slide groove 64, thereby realizing the rotation of the push plate 5 and pushing the coal material inside the coal blending bin 2, preventing the coal material from accumulating inside the coal blending bin 2 and failing to be discharged.

[0021] Please refer to the following: Figures 1 to 6 The control motor 61 is a geared motor, which provides sufficient power for the rotation of the rotating plate 62.

[0022] Please refer to the following: Figures 1 to 6 The two ends of the slider 65 are inclined to prevent coal from accumulating on the top of the two ends of the slider 65 and slipping off.

[0023] Please refer to the following: Figures 1 to 6 The positioning hole 67 and the slide rod 66 slide in close contact. This ensures the stability of the slide rod 66 sliding inside the positioning hole 67 and prevents coal from leaking out in the middle of the positioning hole 67.

[0024] Please refer to the following: Figures 1 to 6The inner walls of the coal blending silo 2 are symmetrically provided with mounting slots 7. A rotating rod 8 is rotatably mounted on the coal blending silo 2 corresponding to the mounting slot 7. A baffle 9 is fixedly mounted in the middle of the rotating rod 8. The baffle 9 is used to shield the area on the lower surface of the baffle 9 in the coal blending silo 2. Torsion springs 10 are symmetrically sleeved at both ends of the rotating rod 8. One end of the torsion spring 10 is fixedly connected to the inner wall of the mounting slot 7 in the coal blending silo 2, and the other end is fixedly connected to one end of the baffle 9. When the push plate 5 reciprocates, the top of the push plate 5 will press against the baffle 9, causing the baffle 9 to rotate. This shields the rotating push plate 5 below the baffle 9, preventing a large amount of coal from appearing below the baffle 9 and affecting the reset of the push plate 5. During the reset process of the push plate 5, the torsion spring 10 will drive the baffle 9 to rotate, moving the baffle 9 to one side of the push plate 5, thus achieving the reset of the baffle 9.

[0025] Please refer to the following: Figures 1 to 6 This solution also includes a coal blending method, comprising the aforementioned coal blending device, and including the following steps: S1. When the device is in use, different types of coal are placed in different coal mixing bins 2. The coal is quantitatively discharged by electromagnetic vibrating feeders 3 at different positions and mixed by conveying through conveyor belt 4. S2. When discharging coal, the rotating plate 62 is controlled by the motor 61. The connecting rod 63 drives the slide rod 66 to slide back and forth inside the positioning hole 67. At the same time, the movement of the slide rod 66 drives the push plate 5 to rotate back and forth. Meanwhile, the slider 65 slides inside the slide groove 64, thereby realizing the rotation of the push plate 5 and pushing the coal inside the coal blending bin 2, preventing the coal from accumulating inside the coal blending bin 2 and failing to be discharged. S3. When the push plate 5 reciprocates, the top of the push plate 5 will press against the baffle 9, thereby causing the baffle 9 to rotate. This will block the push plate 5 rotating below the baffle 9, preventing a large amount of coal from appearing below the baffle 9 and affecting the reset of the push plate 5. When the push plate 5 resets during its reciprocating rotation, the torsion spring 10 will drive the baffle 9 to rotate to one side of the push plate 5, thus achieving the reset of the baffle 9.
