CN201647469U - Anti-blocking structure of coal hopper of power generator unit in power plant - Google Patents

Abstract

The utility model discloses an anti-blocking structure of a coal hopper of a power generator unit in a power plant, comprising a coal storing bin, conical openings and a coal blasting pipe; and the conical openings for connecting the coal storing bin and the coal blasting pipe are asymmetrically distributed along the circumferential direction. The structure avoids blocking in the coal hopper due to the unsmooth coal blasting of coal dust and guarantees the normal operation of the power generator unit in the power plant.

Description

Power generator group coal hopper anti-blocking structure

Technical field

The utility model relates to a kind of power generator group coal hopper anti-blocking structure.

Background technology

The coal breakage bucket provides the main storage supply arrangement of generator set burner hearth fuel, and the smooth and easy operation of fuel is the assurance of the normal operation of generator set in the coal breakage bucket.

As shown in Figure 1, the common similar funnel shaped of coal breakage bucket structure, its coal store 1 to coal spout 3 by bell 2 transition, and bell 2 at circumferencial direction for being symmetrically distributed, be the standard taper.When bunker coal through coal store 1 during by bell 2, bunker coal stressed distribution on bell 2 all directions is uniformly, when coal dust humidity is big, in bell 2 and coal spout 3, cause the bridging phenomenon easily, cause coal breakage not smooth, coal dust stops up, and has influenced the normal operation of generator set.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of power generator group coal hopper anti-blocking structure, and this structure has been avoided not smooth, the phenomenon of blocking of coal dust coal breakage in the coal breakage bucket, has guaranteed the normal operation of power generator group.

For solving the problems of the technologies described above, the utility model power generator group coal hopper anti-blocking structure comprises coal store, bell and coal spout, big mouthful of osculum that connects described coal store, described bell of described bell connects described coal spout, and described bell is skew distribution along the circumferential direction.

Because the utility model power generator group coal hopper anti-blocking structure has adopted technique scheme, the bell that promptly connects coal store and coal spout is a skew distribution at circumferencial direction; This structure has been avoided not smooth, the phenomenon of blocking of coal dust coal breakage in the coal breakage bucket, has guaranteed the normal operation of power generator group.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and embodiments:

Fig. 1 is the structural representation of former power generator group coal breakage bucket,

Fig. 2 is the scheme drawing of the utility model power generator group coal hopper anti-blocking structure.

The specific embodiment

As shown in Figure 2, the utility model power generator group coal hopper anti-blocking structure comprises coal store 1, bell 2 and coal spout 3, big mouthful of osculum that connects described coal store 1, described bell 2 of described bell 2 connects described coal spout 3, and described bell 2 is skew distribution along the circumferential direction.

This structure is designed to skew distribution along the circumferential direction with the bell of coal breakage bucket, and promptly the taper slope of bell is inconsistent, constitutes special-shaped bell; At coal dust when the coal store of coal breakage bucket drops down onto bell, because the asymmetrical design of bell, coal dust is stressed skewness in bell, coal dust forms straggly stressed, avoided the bridging phenomenon of coal dust in bell, coal dust can be fallen in the coal spout swimmingly, guaranteed the smooth coal breakage of coal dust in the coal breakage bucket, thereby guaranteed the normal operation of power generator group.

Claims (1)

1. power generator group coal hopper anti-blocking structure, comprise coal store, bell and coal spout, big mouthful of osculum that connects described coal store, described bell of described bell connects described coal spout, and it is characterized in that: described bell is skew distribution along the circumferential direction.
