Abstract
The utility model provides a coal inlet used on a pulverized coal burner, relates to the coal inlet used on the burner of a rotary kiln, and mainly solves the problems that under the conveying of a coal-conveying air, existing burner pulverized coal is high in resistance when the pulverized coal enters a coal air passage, a coal air inner pipe is easy to be broken through, and air penetration is caused, and use of the burner is affected. The coal inlet comprises a coal air outer pipe, a coal air inner pipe, and a connection pipe connected on the coal air outer pipe. The coal inlet is characterized in that the connection pipe is a circular pipe and is fixed on the coal air outer pipe at a dip angle of 10-14 degrees, and wear-resistant ceramic blocks are adhered to inner walls of the coal air outer pipe and the connection pipe and an outer wall of the coal air inner pipe. The coal inlet is convenient to weld and small in coal-conveying air resistance, the coal air inner pipe can not be broken through, blind coal and even inferior coal can further be burned, and accordingly service life of the burner is improved, user cost is lowered, and the coal inlet is obvious in energy-saving and cost-reducing effects.
Description
Technical field
The utility model relates to the coal feed point on a kind of coal burner, relates to specifically the coal feed point being applied in rotary kiln burner, can be used for the technical fields such as building materials, metallurgy, chemical industry.
Background technology
Multi-channel coal powder combustor is widely used on various rotary kilns, is directly connected to Yield and quality and the energy consumption of kiln.Coal feed point is the coal wind duct entrance of multi-channel coal powder combustor, directly affect the conveying of coal dust, it is a vitals of burner, it is welded by an adapter with certain inclination angle and coal wind outer tube, coal wind inner tube is interted in coal wind outer tube, present burner coal feed point both domestic and external is taken over and is adopted square tube, and be connected with external hose again in order to transition with a hemispherical dome of bolt connection, the angle of itself and coal wind outer tube is 15 °, when coal dust enters coal wind duct under the conveying of the wind of delivering coal, resistance punctures coal wind inner tube greatly and easily, cause and alter wind, affecting burner uses.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, and a kind of coal wind resistance proposing is little, the rotary kiln burner coal feed point of long service life.
Technical solution of the present utility model is: for the coal feed point on burner, comprise coal wind outer tube, coal wind inner tube, be connected to the adapter on coal wind outer tube, it is characterized in that: take over as pipe, adapter is fixed on coal wind outer tube with the inclination angle of 10～14 degree, on coal wind outer tube and nozzle inner wall, and be all pasted with ceramic wear-resisting piece on coal wind outer wall of inner tube.
Adapter described in technical solution of the present utility model is fixed on coal wind outer tube by two blocks of gussets and a shrouding, the hypotenuse of two blocks of gussets is fixed on coal wind outer tube, a right-angle side is fixed in adapter, between two blocks of gussets by shrouding by the outer seal of tube of fishplate bar and coal wind, on two blocks of gussets and shrouding inwall, be pasted with ceramic wear-resisting piece.
the utility model has the advantages that:
The utility model coal feed point convenient welding, the wind resistance of delivering coal is little, and coal wind inner tube there will not be punch-through, can also burn even colm of anthracite, the service life of not only improving burner, and reduce user cost, energy conservation and consumption reduction effects is remarkable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the coal that enters on coal wind outer tube 1 is taken over 3 and is adopted pipes, takes over 3 inclinations and is weldingly fixed on coal wind outer tube 1, take over 3 with coal wind outer tube 1 between angle be 10～14 to spend; Taking over 3 is welded on coal wind outer tube 1 by two blocks of gussets 2 and a shrouding 5, the hypotenuse of two blocks of gussets 2 being axially weldingly fixed on coal wind outer tube 1 along coal wind outer tube 1 that be parallel to each other, a right-angle side of two blocks of gussets 2 is along the below that is axially weldingly fixed on adapter 3 of taking over 3, between another right-angle side of two blocks of gussets 2, being welded with a shrouding 5 will seal between adapter 3 and coal wind outer tube 1, by circle 3, two blocks of gussets 2 of adapter and a shrouding 5, forms the coal feed point on burner; The other end of adapter 3 and flange 6 welding, for with being connected of external hose, end at coal wind outer tube 1 has been welded to connect flange 7, coal wind outer tube 1 interior arranged concentric has coal wind inner tube 8, on the inwall of coal wind outer tube 1 and the outer wall of coal wind inner tube 8, be all stained with ceramic wear-resisting piece 4, take over 3 and two blocks of gussets 2, and on the inwall of shrouding 5, be all pasted with ceramic wear-resisting piece 4.
