Embodiment 1

[0020] see Figure 1-4 , the present embodiment provides a coal pulverizing device for boiler combustion, comprising a device shell 1, a feed port 2, a discharge port 3 and a crushing mechanism; the upper and lower ends of the device shell 1 are respectively provided with feed ports 2 and the discharge port 3, and its inside is provided with a crushing mechanism; the crushing mechanism includes an upper fixed plate 4, a lower fixed plate 5, a left crushing sliding block 6, a right crushing sliding block 7 and a crushing drive mechanism; the The inside of the device shell 1 is fixed with an upper fixed plate 4 and a lower fixed plate 5 sequentially from top to bottom, and there is a gap between the left and right ends of the lower fixed plate 5 and the inner wall of the device shell 1, and the width of the gap is the diameter of the block coal; The left and right ends between the upper fixing plate 4 and the lower fixing plate 5 are fitted and slidably provided with a left grin...

Embodiment 2

[0028] This embodiment is further improved on the basis of Embodiment 1. The improvement is: in order to prevent coal lumps and coal powder from falling into the upper sliding groove and the lower sliding groove respectively, causing the grinding surface 18 and the discharge plate 28 to be unable to Movement; the two ends of the milling surface 18 are fixed with an upper sliding groove baffle 23, and the upper sliding groove baffle 23 fits with the inner wall of the device housing 1, and seals the upper sliding groove above the milling surface 18; The lower side of the discharge plate 28 is fixed with a lower sliding groove baffle 29 , and the lower sliding groove baffle 29 fits the inner wall of the device housing 1 and seals the lower sliding groove above the discharge plate 28 .

Abstract

The invention discloses a coal briquette grinding device for boiler combustion. The device comprises a device shell, a feeding port, a discharging port and a crushing mechanism, wherein the feeding port and the discharging port are formed at an upper end and a lower end of the device shell correspondingly, the crushing mechanism is arranged in the device shell, and the crushing mechanism comprisesan upper fixing plate, a lower fixing plate, a left crushing sliding block, a right crushing sliding block and a crushing driving mechanism. The device has the advantages that through the crushing mechanism, coal briquettes can be further crushed, and thereby the combustion requirement is met; by arranging a powder grinding mechanism, the coal briquettes can be thoroughly crushed and ground intopowder, and thereby combustion of the coal briquettes is more violent.

Description

technical field [0001] The invention relates to the field of boilers, in particular to a coal block grinding device for boiler combustion. Background technique [0002] When using a boiler, fuel is required, most of which use coal as fuel. In order to facilitate the transportation of coal, generally when the factory buys coal, the coal is only primary crushed and turned into lumps, which is convenient for transportation. When coal is used in factory boilers, most of the coal is further crushed, large pieces of coal are crushed into small pieces of coal, and these pieces of coal are placed in the combustion chamber to make them burn automatically. However, due to the relatively small contact area between the lumpy coal and the air, it takes a lot of time to fully burn, and the combustion effect is poor, and it cannot be fully burned. In order to make it burn fully and improve the combustion effect, it is necessary to further pulverize the coal and grind it into powder to ma...
