Description

Technical Field

[0001] This utility model relates to the technical field of pulverized coal feeding devices, specifically a top-mounted self-rotating hoist for pulverized coal feeding. Background Technology

[0002] In the field of pulverized coal feeding, the design of elevators must balance material conveying efficiency and the reliability of tipping and unloading. Existing technologies for lifting and tipping devices for powdery or viscous materials (such as pulverized coal) suffer from the following technical bottlenecks, which urgently require breakthroughs through structural optimization.

[0003] Traditional elevators rely on gravity for unloading, but coal powder is highly adhesive and easily remains in the hopper, requiring manual intervention or mechanical vibration assistance. For example, although vibrating feeding devices clean materials through push plates, the cylinder structure is complex and energy-intensive, and it is prone to wear after long-term use. While the design of vibration unloading with hammers or vibrating motors reduces residue, the continuous operation of the mechanical linkage structure results in high energy consumption and maintenance costs. Therefore, we provide a top-mounted self-turning elevator for coal powder feeding to solve the above-mentioned problems. Utility Model Content

[0008] A top-mounted self-turning elevator for pulverized coal feeding as described above: the belt lifting device includes an inclined conveyor frame set on one side of the frame, two drive rollers rotatably set at both ends of the conveyor frame, a conveyor belt driven by the drive rollers, and multiple storage hoppers set at equal intervals on the conveyor belt;

[0009] The conveyor frame is equipped with a first motor, and one of the transmission rollers is located at the output end of the first motor and is driven to rotate by the first motor.

[0010] As described above, a top-mounted self-rotating elevator for pulverized coal feeding: one end of the rotating frame is hinged to the frame via a hinge.

[0011] As described above, a top-mounted self-rotating hoist for pulverized coal feeding is provided with a limiting groove on the fixed frame, a lead screw rotatably mounted on the inner wall of the limiting groove, an adjusting block movably engaging inside the limiting groove and threadedly engaging with the lead screw, a second motor being provided on the fixed frame, and the output end of the second motor being connected to the lead screw via a coupling to drive the lead screw to rotate.

[0012] As described above, a top-mounted self-reversing hoist for pulverized coal feeding: the limit switch is connected to the vibrating motor via a wire to control the start and stop of the vibrating motor; when the adjusting block slides to one side of the limit switch, the bottom protrusion collides with the rod-shaped contact of the limit switch, and the limit switch controls the vibrating motor to start; when the adjusting block slides away from the limit switch, the bottom protrusion disengages from the limit switch, and the limit switch controls the vibrating motor to shut down.

[0013] As described above, a top-mounted self-turning elevator for pulverized coal feeding has an inclined guide plate at one end of the unloading hopper.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] A rotating tilting frame is mounted on the frame, and a discharge hopper is connected to the top of the tilting frame via a spring, allowing the discharge hopper to tilt. A belt lifting device is used to continuously feed material into the discharge hopper. After feeding, the material is automatically fed into the processing device by tilting the discharge hopper. A vibrating motor is fixed on the discharge hopper, and an adjusting block is slidably mounted on the fixed frame. When the adjusting block moves horizontally, it can drive the hinge rod to deflect and lift the bottom of the discharge hopper to drive the discharge hopper to tilt automatically. At the same time, when the adjusting block moves to the limit switch side, it can cooperate with the limit switch to control the start and stop of the vibrating motor. That is, when the discharge hopper is flat and feeding material, the vibrating motor is off. After the discharge hopper tilts, the vibrating motor is on to vibrate the discharge hopper, achieving the purpose of vibrating discharge.

[0016] This invention combines an external vibrating motor and a tilting structure design in the unloading hopper to automatically trigger vibration during unloading. This reduces reliance on external actuators and ensures that the vibrating motor only starts when the unloading hopper tilts to unload. Compared to the continuous operation of traditional vibrating mechanical linkage structures, this effectively reduces energy consumption. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figures 1 to 7As an embodiment of this utility model, a top-mounted self-rotating elevator for pulverized coal feeding includes a frame 1. A discharge hopper 2 with openings at the top and sides is provided above the frame 1. A belt lifting device for feeding material into the discharge hopper 2 is provided on one side of the frame 1. A rotating frame 9 is rotatably mounted on the frame 1. The discharge hopper 2 and the rotating frame 9 are connected by a spring 11. A vibration motor 12 is provided on the discharge hopper 2. A lifting mechanism for driving the rotating frame 9 to rotate is provided on the frame 1. The lifting mechanism includes a fixed frame 13 mounted on the frame 1. An adjusting block 16 is slidably mounted on the fixed frame 13. A connecting rod 18 is provided on the rotating frame 9. A hinge rod 19 is provided between the connecting rod 18 and the adjusting block 16. The two ends of the hinge rod 19 are hinged to the adjusting block 16 and the connecting rod 18, respectively. A limit switch 20 is provided at the bottom of the connecting rod 18. A protrusion 21 is provided at the bottom of the adjusting block 16.

[0027] In this embodiment, a tilting frame 9 is rotatably mounted on the frame 1. A discharge hopper 2 is connected above the tilting frame 9 via a spring 11. A lifting mechanism is provided on the frame 1 to drive the tilting frame 9 to tilt, thus driving the discharge hopper 2 above the tilting frame 9 to tilt. A belt lifting device is provided to continuously feed material into the discharge hopper 2. After feeding, the material is automatically fed into the processing device by tilting the discharge hopper 2. A vibration motor 12 is fixed on the discharge hopper 2, and an adjusting block 16 is slidably mounted on the fixing frame 13. When the adjusting block 16 moves horizontally, it can drive the hinge rod 19 to deflect and lift the bottom of the discharge hopper 2 to drive the discharge hopper 2 to tilt automatically. At the same time, when the adjusting block 16 moves to the side of the limit switch 20, it can cooperate with the limit switch 20 to control the start and stop of the vibration motor 12. That is, when the discharge hopper 2 is flat and feeding material, the vibration motor 12 is off. After the discharge hopper 2 is tilted, the vibration motor 12 is turned on to vibrate the discharge hopper 2, realizing automatic triggering of vibration during unloading and achieving the purpose of vibration unloading of the discharge hopper 2.

[0028] As a further embodiment of this utility model, a funnel 3 with a bottom opening is provided above the unloading hopper 2, and the bottom opening of the funnel 3 extends to the top opening of the unloading hopper 2.

[0029] In this embodiment, a funnel 3 is provided above the unloading hopper 2. The funnel 3 is located below the material inlet of the belt lifting device, which facilitates the material conveyed by the belt lifting device to be guided into the unloading hopper 2 through the funnel 3.

[0030] As a further embodiment of this utility model, the belt lifting device includes a conveyor frame 4 arranged obliquely on one side of the frame 1, two drive rollers 6 rotatably arranged at both ends of the conveyor frame 4, a conveyor belt 7 cooperating with the drive rollers 6, and multiple storage hoppers 8 arranged at equal intervals on the conveyor belt 7.

[0031] A first motor 5 is installed on the conveyor frame 4, and a transmission roller 6 is located at the output end of the first motor 5 and is driven to rotate by the first motor 5.

[0032] In this embodiment, the first motor 5 is electrically connected to an external power source via a wire. When the first motor 5 is started, it drives the transmission drum 6 to rotate. The transmission drum 6, in conjunction with the conveyor belt 7, drives the conveyor belt 7 to rotate. Since the conveyor belt 7 is equipped with multiple storage hoppers 8, the rotation of the conveyor belt 7 can continuously lift the storage hoppers 8 upward, thereby lifting the coal powder inside the storage hoppers 8 at the bottom of the conveyor belt 7 to the top of the conveyor belt 7. When the coal powder inside the storage hoppers 8 reaches the top of the conveyor belt 7, it is poured into the unloading hopper 2.

[0033] As a further embodiment of this utility model, one end of the flipping frame 9 is hinged to the frame 1 via a hinge 10.

[0034] In this embodiment, one end of the flipping frame 9 is hinged to the frame 1 via a hinge 10, so the flipping frame 9 can be flipped around the hinge point with the frame 1.

[0035] As a further embodiment of this utility model, a limiting groove 14 is provided on the fixed frame 13, and a lead screw 15 is rotatably provided on the inner wall of the limiting groove 14. An adjusting block 16 is movably engaged inside the limiting groove 14 and threadedly engaged with the lead screw 15. A second motor 17 is provided on the fixed frame 13, and the output end of the second motor 17 is connected to the lead screw 15 through a coupling to drive the lead screw 15 to rotate.

[0036] In this embodiment, the second motor 17 is electrically connected to an external power source via a wire. When the second motor 17 is started, it drives the lead screw 15 to rotate. When the lead screw 15 rotates, the adjusting block 16 is threadedly engaged with the lead screw 15, which drives the adjusting block 16 to move horizontally. When the adjusting block 16 moves, it drives the hinge rod 19 to deflect and lift the tilting frame 9, thereby causing the unloading hopper 2 to tilt.

[0037] As a further embodiment of this utility model, the limit switch 20 is electrically connected to the vibration motor 12 via a wire to control the start and stop of the vibration motor 12. When the adjusting block 16 slides to one side of the limit switch 20, the bottom protrusion 21 collides with the rod-shaped contact of the limit switch 20, and the limit switch 20 controls the vibration motor 12 to start. When the adjusting block 16 slides away from the limit switch 20, the bottom protrusion 21 disengages from the limit switch 20, and the limit switch 20 controls the vibration motor 12 to shut down.

[0038] In this embodiment, the limit switch 20 is electrically connected to an external power source via a wire. When the adjusting block 16 slides to one side of the limit switch 20, the bottom protrusion 21 collides with the rod-shaped contact of the limit switch 20, and the limit switch 20 controls the vibration motor 12 to start. When the adjusting block 16 slides away from the limit switch 20, the bottom protrusion 21 disengages from the limit switch 20, and the limit switch 20 controls the vibration motor 12 to turn off. Therefore, when the unloading hopper 2 is placed horizontally for feeding, the vibration motor 12 is off, and the unloading hopper 2 does not vibrate. After the unloading hopper 2 is flipped, the vibration motor 12 turns on to vibrate the unloading hopper 2, thereby achieving the purpose of vibrating the unloading hopper 2 for unloading.

[0039] As a further embodiment of this utility model, one end of the unloading hopper 2 is provided with an obliquely installed guide plate 22.

[0040] In this embodiment, a guide plate 22 installed at an angle is provided at one end of the unloading hopper 2 to guide and transport the material tilted from the unloading hopper 2 into the processing device when the unloading hopper 2 is overturned for unloading.

[0041] In operation, the first motor 5 is started first. The first motor 5 drives the transmission drum 6 to rotate, which in turn drives the conveyor belt 7 to rotate. The rotation of the conveyor belt 7 can continuously lift the storage hopper 8 upward, adding coal powder into the storage hopper 8 at the bottom of the conveyor belt 7. Therefore, the coal powder at the bottom of the conveyor belt 7 can be lifted to the top of the conveyor belt 7. When it reaches the top of the conveyor belt 7, the coal powder in the storage hopper 8 is poured into the discharge hopper 2. A tilting frame 9 is rotatably installed on the frame 1. The discharge hopper 2 is connected to the top of the tilting frame 9 by a spring 11. The spring 11 can elastically extend and retract, allowing the discharge hopper 2 to move up and down when vibrating. The frame 1 is equipped with a lifting mechanism for driving the tilting frame 9 to tilt, thus driving the discharge hopper 2 above the tilting frame 9 to tilt. The hopper 2 is continuously fed into the unloading hopper by a belt lifting device. After feeding, the unloading hopper 2 is automatically fed into the processing device by flipping. A vibration motor 12 is fixed on the unloading hopper 2, and an adjusting block 16 is slidably set on the fixing frame 13. When the adjusting block 16 moves horizontally, it can drive the hinge rod 19 to deflect and lift the bottom of the unloading hopper 2 to drive the unloading hopper 2 to automatically flip. At the same time, when the adjusting block 16 moves to the side of the limit switch 20, it can cooperate with the limit switch 20 to control the start and stop of the vibration motor 12. That is, when the unloading hopper 2 is flat for feeding, the vibration motor 12 is off. After the unloading hopper 2 is flipped, the vibration motor 12 is turned on to vibrate the unloading hopper 2, so as to realize the automatic triggering of vibration during unloading and achieve the purpose of vibration unloading of the unloading hopper 2.

[0042] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
