Embodiment Construction

[0030] Such as figure 1 with figure 2 As shown, a pebble coal isobaric discharge device of the present invention includes a connecting piece 1, a shut-off valve 2, a material guide pipe 3, a sealing box 4, a sealing piece 5 and a moving bucket 6, and the device passes through the connecting piece 1 and the coal grinding The machine stone coal outlet is fixedly connected to ensure that the discharge of the stone coal is in a sealed state. The connecting piece 1, the shut-off valve 2, the guide pipe 3, the sealing box 4 and the sealing piece 5 are fixedly connected in sequence, and the sealing piece 5 and the moving bucket 6 The connection is sealed by a sealing device. The sealing member 5 adopts a double-hook cross-section sealing structure, and the material is high-temperature silicon ester rubber. There is a sealing device between the flange on the moving bucket 6. The device is a double-row straight cylinder 8, which is pressed and sealed, and its effective push The tigh...

Abstract

The invention relates to a device for collecting and cleaning pebble coal discharged by a coal mill; the device comprises a connecting piece (1), a shutdown valve (2), a feeding pipe (3), a sealing box (4), a sealing piece (5) and a moving hopper (6); the connecting piece (1) is fixedly connected with the output of the pebble coal discharged by the coal mill in a sealing way, the connecting piece(1), the shutdown valve (2), the feeding pipe (3), the sealing box (4) and the sealing piece (5) are fixedly connected sequentially, the sealing piece (5) and the moving hopper (6) are connected in asealing way by a sealing device. The device alleviates working intensity of workers, reduces environmental pollution caused by power plants, saves water and electricity consumption of auxiliary equipment and keep the coal mill to be normally operated.

Description

technical field [0001] The invention is an accessory equipment of a coal mill in a power plant, in particular a device for collecting and cleaning pebble coal discharged from the coal mill. Background technique [0002] Pebble coal is a kind of impurity mixed in coal, which must be removed before the coal enters the boiler for combustion, so the pebble coal is separated when the coal mill is running. [0003] At present, coal-fired power plants generally divide the treatment of the pebble coal separated by the coal mill into three types: hydraulic, mechanical and manual transportation. [0004] 1. Manual delivery [0005] Manual transportation mainly includes three parts: gravel coal collection hopper, open movable gravel coal hopper, and dump truck. The part of the gravel coal collection bucket is basically the same under the three methods of hydraulic, mechanical and manual transportation. It is composed of an inlet door, a collection bucket, and an outlet door. The inle...
