Description

Technical Field

[0001] This utility model belongs to the field of unblocking devices, specifically, it relates to an unblocking device for coal bunker inlets. Background Technology

[0002] Most coal bunkers on the market currently adopt a funnel-shaped structure that is wider at the top and narrower at the bottom, relying on the gravity of the raw coal to flow out of the bunker during unloading.

[0003] Chinese Patent CN214085904U discloses a device for clearing blockages at the inlet of a coal bunker in a thermal power plant. When the inlet shell is blocked by coal slag, a motor is started. The output shaft of the motor drives a rectangular rod to rotate. The rectangular rod drives a threaded rod to rotate through a rectangular groove. When the threaded rod rotates on the threaded sleeve, it causes displacement, which in turn drives a rotating plate to rotate and move. The rotating plate drives a stirring rod to make a crankshaft motion. At the same time, the rotating plate pushes the stirring rod to gradually extend into the inlet shell through a sliding through hole. The stirring rod also drives a rotating disk to rotate through the sliding through hole. Thus, the stirring rod extends and makes a crankshaft motion in the inlet shell, thereby achieving the purpose of quickly clearing the blockage of coal slag.

[0004] However, in the aforementioned coal bunker inlet unblocking device for thermal power plants, the stirring rod rotates and propels along a fixed trajectory, resulting in a single movement path. It only cleans coal dust along a fixed annular path, making it difficult to cover the entire cross-section of the inlet shell and creating unblocking dead zones.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a coal bunker inlet unblocking device.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A coal bunker inlet unblocking device includes an inlet housing, a cleaning mechanism on one side of the inlet housing, the cleaning mechanism including a motor mounting frame laterally slidably fitted on one side of the inlet housing, a drive mechanism on one side of the inlet housing for driving the motor mounting frame to slide, a transmission disc rotatably fitted on one side of the motor mounting frame, a material feeding plate elastically slidably fitted on one side of the transmission disc, and a servo motor in the motor mounting frame for driving the transmission disc to rotate.

[0009] Optionally, a baffle is rotatably fitted on the side of the inlet housing. One side of the baffle has a through hole corresponding to the material feeding plate. One end of the material feeding plate is slidably fitted in the through hole. An installation hole is provided on the side of the inlet housing. A first bearing is provided in the installation hole, and the baffle is fixed in the first bearing.

[0010] Optionally, the motor mounting frame is a U-shaped frame structure, the servo motor is fixed on the inner wall of the motor mounting frame, and the output shaft of the servo motor extends out of one end of the motor mounting frame and is fixedly connected to the transmission disk.

[0011] Optionally, the end of the transmission disc is provided with an annular groove, and a second bearing is provided in the annular groove. A ring is provided on the side of the motor mounting frame, and the ring is fixed in the second bearing.

[0012] Optionally, multiple spring dampers are provided on one side of the feed plate, and the spring dampers are fixed on the transmission plate.

[0013] Optionally, the drive mechanism includes a U-shaped frame fixed to the side of the inlet housing and an electric push rod located on one side of the U-shaped frame. The output shaft of the electric push rod extends into the U-shaped frame and is fixedly connected to the motor mounting frame at one end.

[0014] Optional, an inlet shell, with a coal bunker connected to the upper side of the inlet shell.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0016] When the inlet housing is blocked, the drive mechanism is activated to drive the material-pulling plate to insert into the inlet housing. The servo motor is activated to drive the material-pulling plate to rotate intermittently, moving the coal powder inside the inlet housing to facilitate unblocking. When the material-pulling plate rotates to a vertical position and stops intermittently, the drive mechanism drives the transmission disc and the material-pulling plate to move back and forth laterally. The elastic sliding material-pulling plate impacts the inside of the inlet housing, shaking off the coal powder on the inner wall of the inlet housing, which improves the cleaning efficiency and effect of the coal powder inside the inlet housing.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Please see Figure 1-3 As shown, this embodiment provides a coal bunker inlet unblocking device, including an inlet housing 1. A cleaning mechanism 2 is provided on one side of the inlet housing 1. The cleaning mechanism 2 includes a motor mounting frame 201 that is laterally slidably fitted on one side of the inlet housing 1, a drive mechanism 202 located on one side of the inlet housing 1 for driving the motor mounting frame 201 to slide, a transmission disk 203 that is rotatably fitted on one side of the motor mounting frame 201, a material feeding plate 204 that is elastically slidably fitted on one side of the transmission disk 203, and a servo motor 205 located inside the motor mounting frame 201 for driving the transmission disk 203 to rotate.

[0027] When the inlet housing 1 is blocked, the drive mechanism 202 is activated to drive the material-pulling plate 204 to insert into the inlet housing 1. The servo motor 205 is activated to drive the material-pulling plate 204 to rotate intermittently, which moves the coal powder in the inlet housing 1 to facilitate unblocking the inlet housing 1. When the material-pulling plate 204 rotates to a vertical position and stops intermittently, the drive mechanism 202 drives the transmission disc 203 and the material-pulling plate 204 to move back and forth laterally. The elastic sliding material-pulling plate 204 impacts the inside of the inlet housing 1, shaking off the coal powder on the inner wall of the inlet housing 1, which helps to improve the cleaning efficiency and cleaning effect of the coal powder in the inlet housing 1.

[0028] Please see Figure 1-2 As shown, in this embodiment, a baffle 101 is rotatably fitted on the side of the inlet housing 1. A through hole 102 corresponding to the material feeding plate 204 is provided on one side of the baffle 101. One end of the material feeding plate 204 is slidably fitted in the through hole 102. An installation hole 103 is provided on the side of the inlet housing 1. A first bearing is provided in the installation hole 103. The baffle 101 is fixed in the first bearing, which facilitates the improvement of the rotation stability of the baffle 101 through the first bearing. The baffle 101 cooperates with the material feeding plate 204 to rotate and move the coal powder.

[0029] Please see Figure 2-3As shown, the motor mounting frame 201 in this embodiment has a U-shaped frame structure. The servo motor 205 is fixed on the inner wall of the motor mounting frame 201. The output shaft of the servo motor 205 extends out of the motor mounting frame 201 and is fixedly connected to the transmission disk 203. This helps to reduce the probability of the servo motor 205 being damaged by axial compression.

[0030] Please see Figure 1-3 As shown, the transmission disk 203 of this embodiment is provided with an annular groove 206 at its end, and a second bearing is provided in the annular groove 206. A ring 207 is provided on the side of the motor mounting frame 201. The ring 207 is fixed in the second bearing, which facilitates the passage of the second bearing and improves the stability of the transmission disk 203 rotating on the motor mounting frame 201.

[0031] Please see Figure 1-2 As shown, in this embodiment, a plurality of spring dampers 208 are provided on one side of the feeding plate 204. The spring dampers 208 are fixed on the transmission disk 203, so that the feeding plate 204 can slide elastically through the spring dampers 208. When the feeding plate 204 hits the inlet housing 1, the impact intensity is buffered by the spring dampers 208, causing the inlet housing 1 to vibrate and shake off the coal powder on the inner wall of the inlet housing 1.

[0032] Please see Figure 2-3 As shown, the drive mechanism 202 of this embodiment includes a U-shaped frame 2021 fixed to the side of the inlet housing 1 and an electric push rod 2022 disposed on one side of the U-shaped frame 2021. The output shaft of the electric push rod 2022 extends into the U-shaped frame 2021 and is fixedly connected to the motor mounting frame 201. The inlet housing 1 has a rectangular housing structure, which facilitates the sliding of the motor mounting frame 201 by the electric push rod 2022. The upper side of the inlet housing 1 is connected to a coal bunker 104, which facilitates the guidance of coal powder into the inlet housing 1 through the coal bunker 104.
