Abstract
The utility model relates to a cooling device, especially a cooling and connecting structure for end caps of high-temperature sintering resistance furnace tubes. The end cap is composed of a base, a middle casing, and a cover board, a ring-shape water channel is arranged in the middle casing, a cooling water inlet pipe and a cooling water outlet pipe are symmetrically arranged on the outside ring-shape wall of the water channel, bolt holes are symmetrically arranged in the middle casing, through holes opposite to the bolt holes are provided on the base and the cover board, and the through holes and the bolt holes are respectively connected together by the fastening screws in the middle casing for fixing tightly the base and the cover board to the middle casing. The utility model is provided with good sealing effect, which can efficiently reduce or prevent the oxidation and decarbonizing of sintering body.
Description
Technical field
The utility model belongs to cooling device, particularly relates to a kind of high temperature sintering resistance furnace boiler tube end cap cooling and syndeton.
Background technology
For preventing in the boiler tube sintered body oxidation at high temperature even the charcoal phenomenon occurring taking off; protective atmosphere high temperature sintering resistance furnace under the duty must charge into inert gas in its boiler tube, therefore require the end cap of boiler tube should have excellent sealing performance under hot conditions.
End cap in the known technology is made up of base, intermediate sleeve and capping three parts, and wherein intermediate sleeve is connected with whorl of base, and capping and intermediate sleeve are fastening by screw.Base is subjected in the intermediate sleeve bead crimp to be fixed in the boiler tube end by bead sealing ring in it, makes this sealing simultaneously.The composition surface of base and intermediate sleeve, intermediate sleeve and capping is provided with sealing ring respectively.In addition, be provided with the ring pipe of recirculated cooling water in the hugging of intermediate sleeve, the intermediate sleeve outside is provided with the water inlet pipe and water outlet pipe that is communicated with ring pipe.Facts have proved that the sealing effectiveness of above-mentioned end cap is unreliable, its reason is that the intermediate sleeve that is threaded and base rely on and manually is difficult for screwing, and causes bead sealing ring and end-face seal ring distortion in the base not enough and cause the leakage of protective atmosphere.Also contact the slit and influence cooling-down effect, cause the end cap hot-spot, make the coefficient of expansion of each building block of end cap difference occur, cause joint gap to increase and cause the protective atmosphere leakage owing to the ring pipe of recirculated cooling water and the hugging of intermediate sleeve exist.
Summary of the invention
The utility model is in order to solve the insecure technical problem of sealing effectiveness that known high temperature sintering resistance furnace boiler tube end cover structure exists, and cooling of the reliable high temperature sintering resistance furnace of a kind of sealing effectiveness boiler tube end cap and syndeton are provided.
The utility model is taked following technical scheme for the above-mentioned technical problem that solves known high temperature sintering resistance furnace boiler tube end cover structure existence: this end cap is made of base, intermediate sleeve and cover plate, be provided with water annulus in the intermediate sleeve, its cylindrical ring wall is arranged with the cooling water water inlet pipe and water outlet pipe that communicates with it; Base is provided with the corresponding through hole of screw that is symmetrically distributed with intermediate sleeve, each through hole be provided with correspondence be engaged in the intermediate sleeve screw, make the trip bolt of base fluid-tight engagement in intermediate sleeve.
The utility model can also be taked following technical measures:
The interior bead on described intermediate sleeve and base composition surface is provided with the groove of compacting sealing ring.
The beneficial effects of the utility model and advantage are; The water annulus that the intermediate sleeve of this end cap is set, its cooling-down effect makes end cap at high temperature can keep stable sealing property significantly better than the cooling water circulation ring pipe in the known technology.The joint sat of intermediate sleeve and the end is that the trip bolt by instrument is connected, more manually screw reliable for effect, make when screwing to be arranged on the fully distortion under the extruding of intermediate sleeve groove of the sealing ring between the bead and boiler tube in base, the intermediate sleeve composition surface, thereby base is fixed in boiler tube firmly and makes this positiver sealing.The utlity model has good sealing effect, can reduce or avoid the sintered body oxidation effectively and take off the generation of charcoal phenomenon.

The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing thereof.
Embodiment as shown in Figure 1, 2, 3, this end cap is made of the base 1, intermediate sleeve 2 and the cover plate 3 that engage successively, wherein base 1 is set in boiler tube 9 end surfaces, be provided with sealing ring 8 between the interior bead on base 1 and intermediate sleeve 2 composition surfaces and the boiler tube 9, intermediate sleeve 2 is provided with the groove of compacting sealing circle with respect to the interior bead of base 1.Intermediate sleeve 2 its interior annulus wall and boiler tube 9 outer tube wall sliding fits of present embodiment, to guarantee the squeezing effect of its groove to sealing ring 8, the comparison of sealing ring cross-section shape can be found out its tangible distortion among Fig. 2 and Fig. 3.In addition, intermediate sleeve 2 and base 1, intermediate sleeve 2 and the faying face of cover plate 3 are respectively equipped with the relative hugging 6 of insert Fig. 1 sealing ring 8.
Among Fig. 1, intermediate sleeve 2 is symmetrically distributed with 6 screw 2-1, base 1 is respectively equipped with and corresponding base plate through holes 1-1 of screw and cover plate through hole 3-1 with cover plate 3, each through hole be respectively equipped be engaged in the intermediate sleeve screw and make base 1 and cover plate 3 respectively fluid-tight engagement in the base trip bolt 1-2 and the cover plate trip bolt 3-2 of intermediate sleeve.
Find out among Fig. 2,3, be provided with water annulus 7 in the intermediate sleeve 2, its cylindrical ring wall is arranged with cooling water inlet pipe 4 and the outlet pipe 5 that communicates with it.Intermediate sleeve 5 under the user mode makes the cooling water water inlet pipe and water outlet pipe be provided with for vertical, and water inlet pipe 4 is positioned at the bottom side, is beneficial to the circulation of cooling water.
