Abstract
The utility model discloses a plug-type sealed expansion joint of a coal feeder, and solves the problems of coal adhesion and coal blockage phenomena easily caused in the present expansion joint. The plug-type sealed expansion joint is characterized in that an outer ring made of stainless steel plate and provided with two upper claws and two lower claws adopts an arc-shaped and a flat-shaped corrugated board, and the lower claws are connected with stainless steel pipes symmetrically. The plug-type sealed expansion joint can release the thermal expansion or contraction of a coal bunker due to climate changes, and can avoid the phenomenon that the coal is hidden in the expansion joint.
Description
Technical field:
The utility model relates to a kind of expansion joint, relates to a kind of expansion of metal joint that is used for feeder or rather.
Background technology:
The hot and cold distortion of expansion joint available buffer metallic material is a kind of good deflection compensation device, all is widely used in chemical plant and pipeline.The existing expansion joint that is used for equipment such as feeder can draw back a segment distance at the place of combining between the higher and lower levels when shrinking, form a circumference type groove, hides coal, chute blockage easily.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art a kind of plug-in type sealed expansion joint that is used for feeder is provided, with compensation because that climate change causes is flexible, compact conformation, dependable performance seals tight.
Technical solutions of the utility model are characterised in that rolling the outer ring that has two dewclaws, two lower claws with stainless steel sheet is circular arc, pancake corrugated plating, and described lower claw symmetry connects stainless steel tube.
Described stainless steel sheet thickness is 1mm.
Internal diameter between described two dewclaws is 633mm.
Internal diameter between described two lower claws is 650mm.
Distance between the described stainless steel tube external diameter 8mm, two stainless steel tubes is 634mm.
The expansion joint that adopts technique scheme can guarantee former coal bunker because climate change causes under the situation of the 30-50mm that expands with heat and contract with cold can not have problems, and can avoid expansion joint to hide the coal phenomenon.
Description of drawings:
Fig. 1 is a front view of the present utility model.
Fig. 2 is a birds-eye view of the present utility model.
Fig. 3 is an application scheme drawing of the present utility model.
Among the figure, 1. dewclaw, 2. corrugated plating, 3. lower claw, 4. stainless steel tube, 5. coal breakage pipeline section, 6. feeder, the internal diameter between φ 1. dewclaws, the internal diameter between φ 2. lower claws.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, rolling the outer ring that has two dewclaws 1, two lower claws 3 with stainless steel sheet is circular arc, pancake corrugated plating 2, and described lower claw 3 symmetries connect stainless steel tubes 4.Described stainless steel sheet thickness is 1mm, and material is 1 chromium 18 nickel, 9 titaniums or 304.
As shown in Figure 2, the internal diameter φ 1 between two dewclaws 1 is 633mm, and the internal diameter φ 2 between two lower claws 3 is 650mm.Distance between the described stainless steel tube 4 external diameter 8mm, two stainless steel tubes 4 is 634mm.
As shown in Figure 3, two stainless steel tubes 4 of the present utility model are welded on the feeder 6, coal breakage pipeline section 5 welding or the shroud rings of two dewclaws 1 with run coal bin.If welding, the junction is an arc-shaped transition, and the junction can not produce stress concentration like this, can increase coefficient of expansion, alleviates weld seam and shrinks the deformation cracking that causes because of expanding.
Described coal breakage pipeline section 5 external diameters are the 629mm of unification of the motherland, and the slit between the stainless steel tube 4 can directly be inserted in the feeder 6 about 2mm.
Claims (2)
