Description

A snakelike condenser tube structure for heating furnace discharge end

Technical Field

The utility model relates to a snakelike condenser tube structure for heating furnace discharge end.

Background

The end wall all adopts directly to build by laying bricks or stones under the former heating furnace dress discharge end, and inside does not have the steel construction to support, runs into accidents such as falling the steel before the stove and causes the end wall to collapse very easily, and it is longer to resume lower end wall maintenance operation required time at every turn, damages moreover and is unfavorable for production again, in order to strengthen heating furnace discharge end wall structural strength, reduces the many times repetition of the accident of collapsing, must improve lower end wall structure.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a snakelike condenser tube structure for heating furnace discharge end through the cooling of coiled pipe water-flowing, strengthens the cooling effect of headwall down, reduces inside and outside difference in temperature stress, stabilizes the headwall structure simultaneously.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model provides a snakelike condenser tube structure for heating furnace discharge end, includes straight tube section and interval formula set up in a plurality of U type pipeline sections between the straight tube section, the straight tube section with the periphery side of U type pipeline all is provided with a plurality of anchor nails, each the lower extreme of U type pipeline passes through cutting ferrule linking bridge. And connecting pieces used for being connected with the furnace wall are arranged at the positions, close to the inlet and the outlet, of the two ends of the straight pipe section.

Further, the anchoring nails are welded and fixed on the outer wall of the pipe body and are uniformly distributed.

Further, the cutting ferrule includes the semi-circular recess in middle part and the pterygoid lamina at both ends.

Further, the clamping sleeve is connected with the support through a bolt assembly.

Further, the wing plate is connected with the bracket through a bolt assembly.

Furthermore, two ends of the U-shaped pipe section are connected between the straight pipe sections through elbows.

Compared with the prior art, the utility model discloses a beneficial technological effect:

the utility model discloses a coiled pipe leads to water cooling, and the cooling effect of headwall not only can effectually be strengthened, inside and outside difference in temperature stress is reduced, can also the idol stabilize the headwall structure simultaneously, reduces the many times recurrence of the accident of collapsing.

Detailed Description

As shown in fig. 1 to 4, a snakelike cooling water pipe structure for a discharge end of a heating furnace comprises straight pipe sections 1 and a plurality of (4 in this embodiment) U-shaped pipe sections 2 arranged between the straight pipe sections 1 at intervals, wherein a plurality of anchoring nails 3 are arranged on the outer peripheral sides of the straight pipe sections 1 and the U-shaped pipe sections 2, and the lower ends of the U-shaped pipe sections 2 are connected with a bracket 5 through clamping sleeves 4. And connecting pieces 6 used for being connected with a furnace wall are arranged at the positions, close to the inlet and the outlet, of the two ends of the straight pipe section 1.

In this embodiment: the anchoring nails 3 are welded and fixed on the outer wall of the pipe body and are uniformly distributed. The cutting sleeve 4 comprises a semicircular groove in the middle and wing plates at two ends. The wing plate of the cutting sleeve 4 is connected with the bracket 5 through a bolt component.

The utility model discloses at cooling water pipe outer wall interval welding anchor nail, carry out the formwork with the headwall, the mode that adopts the pouring material pouring closes cooling water pipe and headwall interlock as an organic whole, and this kind of pouring mode is built by laying bricks or stones more firmly than direct firebrick, increases the inside and outside stress of coiled pipe cooling elimination well in inside simultaneously, improves the intensity of headwall down, has prolonged its life. The result is more suitable for the furnace condition of the charging and discharging end of the heating furnace in combination.

Comparison of implementation conditions:

the total damage of the lower end wall of the charging and discharging end of the heating furnace is treated 8 times in 2018, 6 times in the discharging end and 2 times in the charging end, the required construction cost is 43747 yuan/time, the material cost is 6500 yuan/ton × 5 ton which is 32500 yuan/time, 609980 yuan is consumed annually, after the lower end wall of the heating furnace is transformed, 2 times of overhaul is expected to be arranged annually to repair the local part of the lower end wall, and the maintenance cost can be saved by 544980 yuan.

The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should also be able to make various modifications and improvements to the technical solution of the present invention without departing from the spirit of the present invention, and all such modifications and improvements are intended to fall within the scope of the present invention as defined in the appended claims.
