The utility model discloses separating the hot-blast barricade that adopts on comb bed upper portion, hot-blast barricade can swing and can height-adjusting again, and it is hot-blast to more effectual utilization, improves the thermal efficiency of the cold machine of comb, can stabilize the secondary and tertiary air temperature of rotary kiln, save the coal consumption to and have higher practical value in the aspect of improving waste heat power generation, improving exhaust gas temperature etc..

The grate beam structure of the grate cooler is mainly formed by welding two webs and a plurality of transverse vertical rib plates in the middle. Because the vertical rib plate has less welding lines, the welding lines of the rib plate are cracked and desoldered due to fatigue under the long-term reciprocating motion action of the grate bed, so that the rigidity of a web plate of the grate beam is seriously insufficient, the grate beam is frequently cracked, the material of a kiln system is greatly reduced, the intermittent shutdown time of the grate cooler is won for rush-repair treatment, and the kiln is stopped for treatment when the rigidity is serious. And the material reduction treatment time is very tight, the high-temperature operation is performed, the welding quality is difficult to ensure, the welding can be well treated by frequently stopping the machine for many times, the production is seriously influenced, and the labor intensity of workers is increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a cold quick-witted comb beam of improved generation comb possesses and has increased the comb beam rigidity, and the welded junction is difficult to the fracture desoldering and improves production efficiency's advantage, has solved the serious not enough and maintenance of comb beam web rigidity and has delayed the problem that time reduces production efficiency.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an improved generation cold quick-witted comb beam of comb, includes upright gusset, web, flat gusset, comb beam and round hole, comb beam upper surface symmetric welding has two webs, upright gusset is the array welding between two webs, upright gusset is located comb beam's horizontal direction, the below of upright gusset is equipped with flat gusset, flat gusset is located comb beam's longitudinal direction, flat gusset welding is in comb beam's bottom, the round hole has been seted up on the flat gusset, round hole evenly distributed is between two upright gussets, the symmetry is installed to comb beam's both ends bottom, the both sides upper end position evenly distributed of web has buckle and draw-in groove.

Preferably, the vertical rib plate is perpendicular to the two web plates.

Preferably, the vertical rib plates are perpendicular to the flat rib plates.

Preferably, the grate beams must be symmetrically welded during welding, and a small hammer is used for knocking the welding line to relieve stress during welding.

Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model discloses add and weld the tie plate bottom whole comb roof beam, greatly increased comb roof beam rigidity, the comb roof beam in-service use effect after reforming transform moreover and consolidate is very good, does not basically have the fracture condition to appear, also has no elasticity swing phenomenon again, has increased the life of comb roof beam, has reduced the number of times of maintenance, has improved production efficiency.
