Detailed Description
As shown in the accompanying drawings, the utility model discloses a one side is open-ended flashboard cell body 1, backplate 2, a set of cross slab 3 and a set of longitudinal baffle 4, flashboard cell body 1 ' S opening side is equipped with round welding groove, 2 welding of backplate is at flashboard cell body 1 ' S opening side, and with flashboard cell body 1 between form the cooling cavity, a set of cross slab 3 from top to bottom arranges in the cooling cavity, and separate into S-shaped cooling channel to the cooling cavity, a set of longitudinal baffle 4 is the form distribution that staggers from top to bottom in S-shaped cooling channel, flashboard cell body 1 ' S one end is equipped with inlet tube 5 and drain pipe 6 respectively, inlet tube 5 communicates with each other with the S-shaped cooling channel of lower one end, drain pipe 6 communicates with each other with the S-shaped cooling channel of higher one end, flashboard cell body 1, a set of cross.
The top of the flashboard groove body 1 is provided with a pair of lifting lugs 7, and the lifting lugs 7 and the flashboard groove body 1 are integrally cast and formed.
Two groups of mutually staggered refining racks 8 are arranged at the bottom of the flashboard groove body 1, and the refining racks 8 and the flashboard groove body 1 are integrally cast and formed.
Inserting grooves 9 corresponding to the group of transverse partition plates 3 and the group of longitudinal partition plates 4 are respectively formed in the inner side of the back plate 2, welding seams 10 are formed at the connecting positions of the inserting grooves of the transverse partition plates 3 and the longitudinal partition plates 4, and one sides of the transverse partition plates 3 and the longitudinal partition plates 4 are located in the corresponding inserting grooves 9 and are welded and fixed with the back plate 2.
The working mode and principle are as follows: flashboard cell body 1, a set of cross slab 3, a set of longitudinal baffle 4, the inlet tube 5, drain pipe 6, lug 7 and refining rack 8 are casting forming as an organic whole, link up the cracked condition of department can not appear under high temperature environment, flashboard cell body 1 'S opening side firing furnace' S face of meeting fire dorsad, S-shaped cooling channel is separated into to a set of cross slab 3 to the cooling cavity, cooling water gets into from the inlet tube 5 of bottom one end, discharge from the drain pipe 6 of top one end again behind S-shaped cooling channel, a set of longitudinal baffle 4 carries out echelonment to S-shaped cooling channel and blocks, make the cooling water can pass through whole cooling cavity in proper order, carry out cooling to flashboard cell body 1.
