Problems solved by technology

[0003] In recent years, my country's development speed has been greatly accelerated, and the power consumption is also very large. Conventional wind power and hydropower generation cannot fully support the electricity consumption in the eastern region of my country. Therefore, thermal power generation is also a part of my country's power demand. However, thermal power generation mostly uses coal as fuel. At th

Embodiment 1

[0029] like figure 1 As shown, the embodiment of the present invention provides an improved fuel processing device for thermal power plants, comprising: a box body 1, the top is provided with a feed port 11, and the side wall of the lower part is provided with a discharge port 12; A grinding and crushing structure 4 and a grinding device 3 are arranged sequentially from top to bottom.

[0030] The rubbing and crushing structure 4 includes: a support body 49, the support body 49 is fixed in the casing 1 below the feed port 12, and the top of the support body 49 is provided with a slot 491 that runs through the support body 49; The guide structure is oppositely provided with two support plates 46, and a plurality of crushing heads 47 are uniformly arranged on the opposite surfaces of the two support plates 46; the drive structure 1 is arranged on the outside of the casing 1, and it is used to drive the two support plates 46 The guiding structure reciprocates horizontally in the...

Embodiment 2

[0035] On the basis of Embodiment 1, in order to make the crushing effect of the coal block better, the two support plates 46 are arranged obliquely, and the distance between the lower ends of the two support plates 46 is smaller than the distance between the upper ends of the two support plates 46 .

Embodiment 3

[0037] On the basis of Embodiment 1, a V-shaped groove is opened on the top of the support body 49, the slot 491 is opened on the inner bottom of the groove, and a plurality of protrusions are evenly distributed on the slope of the groove. From I492.

[0038] Wherein, in order to prevent the large lumps of coal from affecting the crushing effect of the rubbing and crushing structure 4, a crushing structure is provided in the groove, and the crushing structure includes two rollers 5 erected in the groove, and the circumferential direction of the rollers 5 is evenly distributed. A plurality of crushing heads 51 are provided, and the rotating shaft of one of the rollers 5 passes through the casing 1 and is connected with the output shaft of the motor 1 through a coupling, and the rotating shafts of the two rollers 5 are connected by a belt transmission.

[0039] Implemented 4

[0040] On the basis of Embodiment 1, a material guide plate 3 is also included, which is arranged obli...

Abstract

The invention relates to an improved fuel processing device for a thermal power plant. The device a box body and a driving structure I, the top of the box body is provided with a feed inlet, and the side wall of the lower part of the box body is provided with a discharge outlet; a rubbing and grinding crushing structure and a grinding device are sequentially arranged in the box body from top to bottom, the rubbing and grinding crushing structure comprises a supporting body, the supporting body is fixed in the position, below the feed inlet, of the box body, and a groove seam penetrating through the supporting body is formed at the top of the supporting body; and two supporting plates are oppositely arranged in the groove seam through a guide structure, and a plurality of crushing heads are evenly distributed on the opposite faces of the two supporting plates. The driving structure I is arranged outside the box body and used for driving the two supporting plates to horizontally reciprocate in the groove seam through the guide structure, and the movement directions of the two supporting plates are always opposite. The device improves the processing efficiency of coal briquettes by arranging the rubbing and grinding crushing structure, improves the processing effect, prolongs the service life of the grinding structure, and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of fuel processing, in particular to an improved fuel processing device for thermal power plants. Background technique [0002] Thermal power refers to the conversion of heat energy generated by the combustion of solid and liquid fuels such as coal, oil, and natural gas into kinetic energy to produce electricity. [0003] In recent years, my country's development speed has been greatly accelerated, and the power consumption is also very large. Conventional wind power and hydropower generation cannot fully support the electricity consumption in the eastern region of my country. Therefore, thermal power generation is also a part of my country's power demand. However, thermal power generation mostly uses coal as fuel. At the same time, the coal needs to be processed. Because the pulverized coal furnace for power generation needs to grind the coal into irregular fine coal particles, the existing coal mills first ...
