Abstract

The utility model discloses a strip-shaped turnover coal furnace grate piece without leakage, which relates to the technical field of the grate and solves the defects that the boiler grate piece which is provided with labyrinth type ventilation holes has difficult processing and hard realization, the grate piece is larger and is heated unevenly to cause cracking easily, and the ventilation holes of the grate piece easily clamp cinder and gangue to influence the ventilation. The first aspect of the concrete solution technical scheme is that the utility model is divided into a furnace grate piece A and a furnace grate piece B which are matched for use and are both in a long strip body shape. One end of the upper plane of the long strip shape is provided with a downwards concave circular bead, a wall which is provided with a fixing hole is arranged below the position corresponding to the circular bead, and the other end of the upper plane of the long strip shape is provided with a blocking edge. Both sides of the upper plane of the long strip shape of the furnace grate piece A are provided with the blocking edges, and both sides of the upper plane of the long strip shape of the furnace grate piece B are provided with the downwards concave circular beads. The second aspect is that the furnace grate piece is in the long strip body shape, one end of the upper plane of the long strip shape is provided with the downwards concave circular bead, the wall which is provided with the fixing hole is arranged below the position corresponding to the circular bead, and the other end of the upper plane of the long strip shape is provided with the blocking edge. One side of the upper plane of the long strip shape is provided with the downwards concave circular bead, and the other side is provided with the blocking edge.

Description

The turning nothing of bar shaped is leaked the coal stove screening

Technical field

The utility model relates to the fire grate technical field, particularly relates to the turning nothing of a kind of bar shaped and leaks the screening of coal chain furnace.

Background technology

The patent No. is a kind of boiler grate of 01277021.3, the technology that has butt joint straight slot problem between existing Industrial Boiler traveling-grate stoker rotating plate and big fire grate segment that solves is provided, application number is a kind of boiler fire bar sheet with labyrinth type air vent of 200420092319.3, the technology that has direct ventilation hole problem on the existing big fire grate segment of Industrial Boiler traveling-grate stoker that solves is provided, though the duff when above-mentioned The Application of Technology can solve boiler operatiopn on the fire grate is easily from the bleed deficiency of air compartment of fire grate, but boiler fire bar sheet with labyrinth type air vent, exist processing to be difficult for realizing again, difficulty of processing is big, fire grate segment is heated more greatly, and inequality is easy to produce cracking, and the easy slag inclusion of fire grate segment air vent, dirt band influences deficiency in draught.

The utility model content

The technical problems to be solved in the utility model is that the boiler fire bar sheet that has the labyrinth type air vent in the existing Industrial Boiler traveling-grate stoker exists difficulty of processing big, is difficult for realizing; The fire grate segment uneven cracking that easily produces that is heated more greatly; The easy slag inclusion of fire grate segment air vent, dirt band influence deficiency in draught.

For solving the problems of the technologies described above, the coal stove screening is leaked for the turning nothing of a kind of bar shaped is provided in first aspect of technical solution adopted in the utility model, it is divided into fire grate segment A and the fire grate segment B that matches and use, described fire grate segment A and fire grate segment B are the rectangular bodily form, plane one end has recessed shoulder on the strip, one wall that has a fixing hole is arranged below the corresponding shoulder place, the plane other end has the retaining edge on the strip, there is the retaining edge both sides, plane on the described fire grate segment A strip, and there is recessed shoulder the both sides, plane on the described fire grate segment B strip.The coal stove screening is leaked for the turning nothing of a kind of bar shaped is provided in second aspect of the technical scheme of being taked, described fire grate segment is a rectangular bodily form, plane one end has recessed shoulder on the strip, one wall that has a fixing hole is arranged below the corresponding shoulder place, the plane other end has the retaining edge on the strip, plane one side has recessed shoulder on the strip, and opposite side has the retaining edge.

The utility model compared with the prior art, because fire grate segment is designed to the rectangular bodily form, volume is less, own no air vent on the fire grate segment, in the technical scheme of taking aspect first, ventilate main by both sides, plane retaining on the described fire grate segment A strip that cooperates alternately along with described fire grate segment B strip on the labyrinth ventilating duct that forms of the recessed shoulder matched in clearance in both sides, plane realize; Aspect second of the technical scheme of taking, the main shoulder with retaining by the downward concave station of planar side on the adjacent fire grate segment strip of ventilating realized along the labyrinth ventilating duct that matched in clearance forms.Its beneficial effect is to make fire grate in the advantage that keeps using the boiler fire bar sheet with labyrinth type air vent not have the leakage coal simultaneously, make the fire grate segment difficulty of processing little again, easily realize, be heated and comparatively evenly be difficult for producing cracking, there are not slag inclusion on the fire grate segment, dirt band problem, when the labyrinth ventilating duct slag inclusion that forms between fire grate segment, dirt band, the removal of can being scattered when fire grate segment runs to the upset of fire grate afterbody does not influence boiler draft.
