[0002] During the storage and transportation of coal, the coal drop pipe is a key component in the coal bunker that transports coal to downstream equipment. In the prior art, the coal drop pipe is often blocked due to unreasonable design or long-term use.

[0027] Example 1

[0028] Reference Figure 1 , which is the first embodiment of the present invention, provides a coal bunker coal drop pipe anti-blocking pipeline, which includes a pipeline component 100 and an anti-blocking component 200, which can reduce the coal drop flow rate at the coal inlet by adjusting the anti-blocking component 200 to achieve the anti-blocking effect.

[0029] Specifically, the pipeline assembly 100 includes a coal hopper 101, an upper feed pipe 102 fixedly connected to the lower part of the coal hopper 101, and a discharge pipe 103 disposed at the lower part of the upper feed pipe;

[0032] Example 2

[0033] Reference Figures 1 to 4 , which is the second embodiment of the present invention, provides a coal bunker coal drop pipe anti-blocking pipeline, which includes a pipeline component 100 and an anti-blocking component 200, which can reduce the coal drop flow rate at the coal inlet by adjusting the anti-blocking component 200 to achieve the anti-blocking effect.

[0034] Specifically, the pipeline assembly 100 includes a coal hopper 101, an upper feed pipe 102 fixedly connected to the lower part of the coal hopper 101, and a discharge pipe 103 disposed at the lower part of the upper feed pipe;

[0035] The anti-blocking component 200 includes a shell 201, a flange ring 202 connected to the upper and lower ends of the shell 201 respectively, a driving motor 203 fixedly connected to the upper part of the shell 201, a rotating ring 204 arranged in the inner cavity of the shell 201, and an adjusting cylinder 205 fixedly connected to the inner cavity of the shell 201.

[0036] Furthermore, the rotating ring 204 includes a ring body 204a connected to the driving motor 203, and a plurality of driving columns 204b are arranged in a circular array inside the ring body 204a.

[0037] Furthermore, the ring body 204a is rotatably connected to the housing 201, and the driving column 204b is fixedly connected to the inner wall of the ring body 204a.

[0038] Furthermore, the regulating cylinder 205 includes a cylinder body 205a which is wide to narrow in the direction from the coal dropping hopper 101 to the discharge pipe 103, a plurality of groups of trigger plates 205b which are evenly distributed in a ring shape on the outside of the cylinder body 205a, a telescopic slide rod 205c which is rotatably connected to the trigger plate 205b, a connecting rod 205d which is fixedly connected to the bottom of the trigger plate 205b, and an arc plate 205e which is fixedly connected to the connecting rod 205d, which can reduce the coal dropping flow rate and perform a ring-shaped cutting on the coal dropping cycle.

[0039] Furthermore, the cylinder 205a is fixedly connected to the housing 201, and the telescopic slide rod 205c is rotatably connected to the outer wall of the cylinder 205a and is also evenly distributed in a ring shape on one side of the trigger plate 205b.

[0040] Furthermore, the arc plate 205e includes a plate body 205e-1, two groups of support rods 205e-2 fixedly connected to the plate body 205e-1, an arc rod 205e-3 fixedly connected to the upper part of the support rod 205e-2, and a rotating plate 205e-4 fixedly connected to one end of the arc rod 205e-3 close to the cylinder 205a.

[0041] Furthermore, the rotating plate 205e-4 is rotatably connected to the bottom of the cylinder 205a, and the rotating plate 205e-4 is fixedly connected to the arc rod 205e-3 and the connecting rod 205d respectively.

[0042] Furthermore, the four sides of the plate body 205e-1 are all arc surfaces, the arc surfaces on the left and right sides of the plate body 205e-1 have the same angle, the upper and lower parts of the plate body 205e-1 are both arc surfaces, and the plates 205e-1 touch each other and can be connected to form an annular plate.

[0043] Furthermore, a spring is provided inside the telescopic slide rod 205c, so that the telescopic slide rod 205c can be in a retracted state when no external force is applied.

[0044] Furthermore, the contacting side of the trigger plate 205b and the cylinder 205a is at a certain angle, and the plate body 205e-1 can be connected to form a circular ring plate after rotating along the same angle.

[0045] Preferably, the rotating ring 204 is driven to rotate by the driving motor 203, and the rotating ring 204 is connected to the housing 201 to generate a rotation with the discharge tube 103 as the axis. At this time, the rotating ring 204 will drive the driving column 204b to rotate at the same time. When a plurality of groups of driving columns 204b rotate, they will touch the trigger plate 205b at intervals. When the driving column 204b touches the trigger plate 205b, the trigger plate 205b will rotate along the rotation direction of the driving column 204b through the telescopic slide bar 205c with the rotating plate 205e-4 as the axis, and pull The movable telescopic slide rod 205c is stretched and rotates with the connection between the telescopic slide rod 205c and the cylinder 205a as the axis. At the same time, when the trigger plate 205b rotates, the connecting rod 205d and the rotating plate 205e-4 will be driven to rotate at the same time. When the rotating plate 205e-4 is rotated, the plate body 205e-1 is fixed by the support rod 205e-2 and the arc rod 205e-3 with the rotating plate 205e-4 as the axis to rotate at the same angle as the trigger plate 205b. At this time, several groups of plate bodies 205e-1 will rotate at the same time and roughly mesh to form a circular ring plate.

[0046] Preferably, the plate body 205e-1 will intermittently form an annular plate when the rotating ring 204 rotates. The annular plate will block the coal from falling from the edge of the coal dropping pipe wall to a certain extent, thereby making the coal fall closer to the center of the discharge pipe 103 and reducing a certain amount of coal falling flow rate, thereby preventing the discharge pipe 103 from being blocked due to excessive load.

[0047] Preferably, the rotation speed of the driving motor 203 is adjusted to drive the rotating ring 204 to rotate faster. At this time, the plate body 205e-1 will also quickly and continuously squeeze the trigger plate 205 through the driving column 204b when the rotating ring 204 rotates. At this time, the trigger plate 205 will rotate at a faster rate and drive the arc plate 205e in the same way, so that the annularly distributed plate body 205e-1 forms an annular cut through the sharp cutting surface on the lower side to the position where the circular ring plate should be formed. The reciprocating cycle greatly reduces the volume of the coal block, and under the same circulation rate, the larger the coal block, the greater the probability of being cut, thereby greatly reducing the average size of the coal block, thereby achieving the effect of preventing blockage.

[0048] It should be noted that the driving motor 203 can drive the rotating ring 204 to rotate through the existing technology, and can drive the rotating ring 204 to rotate by setting gears or pulleys, etc. The driving column 204b and the arc plate 205e can be set in the same group and are evenly distributed in a ring shape. When the plate body 205e-1 rotates to touch each other, the circular ring plate formed is a larger circular ring plate close to the coal hopper 101 and gradually decreases along the direction of the discharge pipe 103. The side wall section of the plate body 205e-1 can be set to an angle of about 45° to 75° relative to the ground.

[0049] First, the anti-blocking assembly 200 is installed at the bottom of the upper feed pipe 102 and the top of the discharge pipe 103 through the flange ring 202 .

[0050] Then, when the pipeline pressure is high and cannot bear the coal flow rate of the coal hopper 101 and often causes blockage, the driving motor 203 can be turned on to drive the rotating ring 204 to rotate. The rotating ring 204 rotates with the discharge pipe 103 as the axis through the rotation connection with the shell 201. At this time, the rotating ring 204 will drive the driving column 204b to rotate at the same time. When several groups of driving columns 204b rotate, they will touch the trigger plate 205b at intervals. When the driving column 204b touches the trigger plate 205b, the trigger plate 205b will rotate with the rotating plate 205e through the telescopic slide rod 205c. -4 is the axis that rotates along the rotation direction of the driving column 204b, and pulls the telescopic slide rod 205c to stretch and rotate with the connection between the telescopic slide rod 205c and the cylinder 205a as the axis. At the same time, when the trigger plate 205b rotates, the connecting rod 205d and the rotating plate 205e-4 will be driven to rotate at the same time. When the rotating plate 205e-4 is rotated, the plate body 205e-1 is fixed by the support rod 205e-2 and the arc rod 205e-3 and rotates with the rotating plate 205e-4 as the axis to the same angle as the trigger plate 205b. At this time, several groups of plate bodies 205e-1 will rotate at the same time and roughly mesh to form a circular ring plate.

[0051] The first usage of the arc plate 205e is that the plate body 205e-1 will intermittently form a circular plate when the rotating ring 204 rotates. The circular plate will block the coal from falling from the edge of the coal drop pipe wall to a certain extent, thereby making the coal fall closer to the center of the discharge pipe 103 and reducing a certain amount of coal falling flow rate to prevent the discharge pipe 103 from being blocked due to excessive load.

[0052] The second way to use the arc plate 205e is to adjust the rotation rate of the driving motor 203 to drive the rotating ring 204 to rotate faster. At this time, the plate body 205e-1 will also quickly and continuously squeeze the trigger plate 205 through the driving column 204b when the rotating ring 204 rotates. At this time, the trigger plate 205 will rotate at a faster rate and drive the arc plate 205e in the same way, so that the annularly distributed plate body 205e-1 forms a circular cut through the sharp cutting surface on the lower side to the position where the circular ring plate should be formed. The reciprocating cycle greatly reduces the volume of the coal block, and under the same circulation rate, the larger the coal block, the greater the probability of being cut, thereby greatly reducing the average size of the coal block, thereby achieving the effect of preventing blockage.

[0053] In summary, the present invention provides an anti-blocking component. When the coal pipe cannot bear the falling coal flow rate and causes frequent blockages, the anti-blocking component can be started, so that the anti-blocking component can reciprocate to reduce the coal falling rate under the drive of the driving motor, or the anti-blocking component can be continuously opened when the coal pipe has a long-term blockage problem. The arc plate is cyclically closed to form a ring body, and the sharp cut surface forms a ring-shaped cut on the falling coal when the arc plate rotates, so as to reduce the coal falling flow rate of the lower coal pipe or reduce the proportion of large-volume coal pipes to reduce the occurrence of blockage in the coal pipe.
