Description

Technical Field

[0001] The utility model relates to the field of coal feeders, in particular to a coal feeder bunker collapse protection mechanism. Background Art

[0002] Coal feeder bunker bursts due to excessive coal discharge or coal and water backlog. Coal feeder bunker bursts cause subsequent sections to operate at overload, which in turn affects the normal operation of subsequent sections, resulting in coal backlogs that affect normal production operations, and in serious cases, safety accidents. In the prior art, technical innovations for bunker bursts are mainly aimed at preventing bunker bursts, but they still cannot prevent the occurrence of bunker bursts.

[0003] To solve the above problems, a safety protection device for preventing bunker collapse is disclosed in Chinese patent 202020407015.0. After the bunker collapses, the device uses a hydraulic device to vertically press down the piston rod part, thereby cutting off the coal flow. However, the disadvantages of the device are obvious. After the bunker collapses, the coal flow continues to be discharged. The downward movement of the piston part is actually to overcome the impact pressure of the coal flow from the vertical direction. On the one hand, it will cause the piston part to move down unsmoothly. On the other hand, after being impacted by the coal flow, the piston part is severely deformed and cannot be used again. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a coal feeder bunker collapse protection mechanism which has a simpler structure, can block the coal flow in the coal feeder, and can be reused.

[0005] The equipment is assembled on the coal discharge chamber of the coal feeder, and includes a coal flow baffle and a first baffle restraining unit;

[0006] The coal flow baffle is rotatably arranged on the upper part of the coal outlet chamber of the coal feeder;

[0007] A first baffle restraint unit is arranged on the rear part of the coal discharge chamber, and the first baffle restraint unit includes a push rod mechanism, and a bent rod is fixedly connected to the piston of the push rod mechanism, and the bent rod passes through the side panel of the coal discharge chamber from the outside to the inside; and a baffle storage gap is left between the bent rod and the bottom surface of the upper panel of the coal discharge chamber.

[0008] Furthermore, the height of the coal flow baffle is greater than the height of the coal discharge chamber.

[0009] The effect achieved by this is that, in the standby state, the baffle is arranged to fit under the upper panel of the coal discharge chamber, and the curved rod is used as a limit to prevent the baffle from rotating downward to block the coal discharge;

[0010] When coal collapse occurs, the push rod mechanism pushes the bent rod outward, and the bent rod separates from the coal flow baffle. The coal flow baffle naturally rotates and falls downward due to its own weight and the impact of the coal flow until its bottom approaches or fits the lower panel of the coal discharge chamber, thereby preventing the coal from continuing to flow out.

[0011] The beneficial effects of the utility model are as follows: compared with similar products in the prior art, the utility model has a simpler structure, and the arrangement form based on this is more reasonable and durable. Through a simple structure, after the coal feeder is collapsed, the baffle is separated from the first baffle constraint unit, and naturally and stably rotates downward under the action of its own weight and the impact of the coal flow, thereby achieving the coal blocking effect. In addition, the connecting mechanisms in the implementation process are restrained and protected by the assembly pipe to prevent deformation, and the baffle can be replaced separately after serious deformation, which is conducive to extending the service life of the mechanism and reducing the layout cost.

[0017] Reference Figure 1 , Figure 2 The coal feeder bunker collapse protection mechanism described in the utility model comprises a coal flow baffle 4 and a first baffle restraining unit;

[0018] The coal flow baffle 4 is rotatably arranged on the upper part of the coal outlet chamber 7 of the coal feeder;

[0019] A first baffle restraint unit is arranged on the rear part of the coal discharge chamber 7, and the first baffle restraint unit includes a push rod mechanism 1, and a bent rod 3 is fixedly connected to the piston of the push rod mechanism 1, and the bent rod 3 is arranged to pass through the side panel of the coal discharge chamber 7 from the outside to the inside; and a baffle storage gap is left between the bent rod 3 and the bottom surface of the upper panel of the coal discharge chamber 7.

[0020] Furthermore, the height of the coal flow baffle 4 is greater than the height of the coal discharge chamber 7 .

[0021] The effect achieved by this is that, in the standby state, the baffle is arranged to fit under the upper panel of the coal discharge chamber 7, and the curved rod 3 is used as a limit to prevent the baffle from rotating downward to block the coal discharge;

[0022] After coal collapse occurs, the push rod mechanism 1 moves to push the curved rod 3 outward, and the curved rod 3 separates from the coal flow baffle 4. The coal flow baffle 4 naturally rotates and falls downward due to its own weight and the impact of the coal flow until its bottom approaches or fits the lower panel of the coal outlet chamber 7, thereby preventing the coal from continuing to flow out.

[0023] Furthermore, a second baffle constraint unit is provided on the side panel of the coal discharge bin chamber 7, and the second baffle constraint unit includes an assembly tube A6 passed through the side panel of the coal discharge bin chamber 7, a baffle rod 5 is passed through the assembly tube A6, and pin holes are correspondingly provided on the baffle rod 5 and between the assembly tube A6, and pins are correspondingly passed between the baffle rod 5 and the assembly tube A6.

[0024] The effect achieved by this is that after the coal flow baffle 4 rotates and falls, the bottom of the second baffle constraint unit contacts the bottom surface of the coal discharge chamber 7 in the implementation state, which plays a further supporting role for the baffle.

[0025] Furthermore, two groups of the second baffle restraining units are provided, and the second baffle restraining units are provided on two side panels of the coal discharge bin chamber 7 and are provided at opposite positions.

[0026] Furthermore, the first baffle restraining units are provided with two groups, which are arranged on the upper panel of the coal discharge bin chamber 7 and are arranged at opposite positions.

[0027] Furthermore, the push rod mechanism 1 is a hydraulic cylinder or a pneumatic cylinder.

[0028] Furthermore, an assembly pipe B2 is also provided on the side panel of the coal discharge bin chamber 7, and the bent rod 3 is inserted into the assembly pipe B2, and the outer surface of the bent rod 3 is fitted with the inner surface of the assembly pipe B2.

[0029] The effect achieved in this way is to prevent the bending rod 3 and the push rod mechanism 1 from being deformed, thereby ensuring the service life of the equipment.

[0030] Furthermore, two opposing baffle assembly pipes are provided on the upper part of the coal discharge chamber 7;

[0031] The upper side of the coal flow baffle 4 is respectively provided with assembly rods, and the assembly rods are rotatably arranged in the assembly pipe, that is, the rotation connection of the coal flow baffle 4 is realized, and the effect of facilitating the replacement of the coal flow baffle 4 alone is achieved.

[0032] Preferably, the push rod mechanism 1 is connected to a warehouse collapse warning unit by signal, and the warehouse collapse warning unit includes a probe and a processor. That is, after the probe detects a warehouse collapse, it reports it to the processor, and the processor controls the push rod mechanism 1 to move.
