Description
Technical Field
The utility model relates to a high temperature tube subassembly.
Background
A hot air inlet branch pipe, an air outlet branch pipe and a plurality of rectangular pipes for supporting a high-temperature ring pipe are uniformly distributed on an upper heating bin section and a lower heating bin section of the deposition furnace. Specifically, the ring pipe is positioned on the periphery of the inner container and the heat-preservation cooling furnace shell. The inner end of the branch pipe is communicated with the cooling furnace shell in a welding mode, and the outer end of the branch pipe is communicated with the ring pipe in a welding mode. The inner end of the rectangular pipe is welded with the support on the outer surface of the cooling furnace shell, and the outer end of the rectangular pipe is welded with the ring pipe.
The temperature of the loop pipe is very high because the loop pipe is contacted with high-temperature hot air. Because the inside heat preservation cotton that has of cold stove shell, and cold stove shell can contact with external atmosphere for the temperature of cold stove shell is close to the normal atmospheric temperature, and the temperature is lower. Therefore, the outer ends of the branch pipes and the ring pipes generate thermal expansion displacement together, and the inner ends of the branch pipes and the cooling furnace shell do not generate thermal expansion displacement. Therefore, the two ends of the branch pipe have thermal expansion difference, so that the joints of the branch pipe and the ring pipe and the joints of the branch pipe and the cold furnace shell can generate high local stress, and the branch pipe and the ring pipe and the branch pipe and the cold furnace shell are welded and cracked. In a similar way, the two ends of the rectangular pipe have thermal expansion difference, so that the welding between the rectangular pipe and the ring pipe and between the rectangular pipe and the upright post is invalid.
In order to ensure the connection reliability of the branch pipe and the ring pipe and the connection reliability of the branch pipe and the cold furnace shell, the prior method adopts the following measures: the ring pipe is divided into a plurality of sections, and the sections are connected by telescopic sleeves. However, the circumferential expansion displacement at the joint of the branch pipe and the ring pipe still causes the high local stress generated at the joint of the branch pipe due to deformation coordination, and the high local stress is transmitted to the joint of the branch pipe and the cold furnace shell through the branch pipe, so that the welding seam is cracked. Similarly, the welds between the rectangular tubes and the collars and between the rectangular tubes and the posts are still prone to failure.
In summary, the connections between the components of the prior art high temperature tube assemblies are susceptible to failure.

As shown in fig. 1, the present embodiment discloses a high temperature pipe assembly including an inner vessel 1, a cooling furnace shell 2, a support 3 provided on an outer surface of the cooling furnace shell 2, a support 4, a sleeve 5, and a collar 7. In the present embodiment, the high temperature tube assembly is applied to a deposition furnace. In other alternative embodiments, the high temperature tube assembly may also be applied to other devices.
The inner container 1 is arranged in the inner cavity of the cooling furnace shell 2. The diameter of the ring pipe 7 is larger than that of the cooling furnace shell 2, and the ring pipe 7 is sleeved on the periphery of the cooling furnace shell 2. Since the loop pipe 7 is in contact with the hot blast of high temperature, the temperature of the loop pipe 7 is high. The inside of cold stove outer covering 2 has the heat preservation cotton, and cold stove outer covering 2 can contact with external atmosphere for the temperature of cold stove outer covering 2 is close to the normal atmospheric temperature, and the temperature is lower. That is, the temperature of the furnace cooling shell 2 of the present embodiment is lower than the temperature of the bustle pipe 7, and there is a large temperature difference between the furnace cooling shell 2 and the bustle pipe 7. This makes the parts between the cold furnace shell 2 and the bustle pipe 7 susceptible to connection failure due to such temperature differences.
The high-temperature pipe assembly of this embodiment also includes branch pipe 8, and the inner of branch pipe 8 is connected with cold furnace shell 2, and the outer end of branch pipe 8 is connected with ring pipe 7. The outer ends of the branch pipes 8 and the bustle pipes 7 are liable to be displaced together by thermal expansion, resulting in local stresses between the inner ends of the branch pipes 8 and the furnace shell 2 and between the outer ends of the branch pipes 8 and the bustle pipes 7.
If the overall deformability of the branch pipes 8 is weak, the connection between the inner ends of the branch pipes 8 and the furnace shell 2 is prone to failure due to local stress, and the connection between the outer ends of the branch pipes 8 and the bustle pipe 7 is prone to failure due to local stress. In order to improve the reliability of the connection of the inner ends of the branch pipes 8 to the furnace shell 2 and the outer ends of the branch pipes 8 to the bustle pipe 7, the branch pipes 8 of this embodiment comprise a branch pipe section and a bellows pipe section 6 which are connected and both extend radially.
In the embodiment, the corrugated pipe sections 6 are arranged on the branch pipes 8, so that the deformation capacity of the branch pipes 8 can be improved, the local stress between the inner ends of the branch pipes 8 and the cooling furnace shell 2 and between the outer ends of the branch pipes 8 and the ring pipes 7 can be reduced, and the connection reliability between the inner ends of the branch pipes 8 and the cooling furnace shell 2 and between the outer ends of the branch pipes 8 and the ring pipes 7 can be improved.
In the present embodiment, the branch pipe 8 includes a branch pipe section, the bellows section 6, and a branch pipe section in this order in a direction from the inner end of the branch pipe 8 to the outer end of the branch pipe 8. The two sides of the corrugated pipe section 6 are branch pipe sections, the inner end of the branch pipe 8 is conveniently connected with the cooling furnace shell 2, and the outer end of the branch pipe 8 is conveniently connected with the ring pipe 7. In this embodiment, the length of the inner branch pipe section is longer, the length of the outer branch pipe section is shorter, and the length of the bellows section 6 is longer than the outer branch pipe section and shorter than the inner branch pipe section. In other alternative embodiments, the lengths of the inner leg sections, the bellows sections 6 and the outer leg sections may be set as desired.
In other alternative embodiments, the branch pipe 8 may comprise only one branch pipe section and only one corrugated pipe section 6. In other alternative embodiments, the branch pipe 8 may further comprise at least one branch pipe section and at least one corrugated pipe section 6, and the branch pipe section and the corrugated pipe section 6 may be arranged alternately in the radial direction.
The branch pipe segment of the embodiment can be of the same structure as the existing branch pipe, for example, the branch pipe segment is of a cylindrical straight pipe structure and is weak in deformability.
In this embodiment, the inner ends of the branch pipes 8 are welded to the furnace shell 2, and the outer ends of the branch pipes 8 are welded to the collar 7. At this time, the branch pipe 8 of the present embodiment includes the bellows section 6, and the connection reliability of the inner end of the branch pipe 8 and the cold furnace shell 2 can be significantly improved, and the weld breakage can be prevented. Similarly, the reliability of the connection between the outer end of the branch pipe 8 and the collar pipe 7 can be remarkably improved, and the welding fracture can be prevented.
In this embodiment, the high temperature tube assembly further comprises a support body 4, a sleeve 5 and a pillar 3 arranged on the outer surface of the cooling furnace shell 2, the pillar 3 extending perpendicular to the support body 4 and the sleeve 5. The pillars 3 are used to improve the strength and rigidity of the cooling furnace shell 2. The inner of support body 4 and the outer end welded connection of pillar 3, the outer end of support body 4 and the inner of sleeve pipe 5 cup joint the cooperation, and have the clearance with the outer wall of ring pipe 7 between, and what this clearance set up is less to make support body 4 play the effect of supporting ring pipe 7, can give support body 4 certain deformation space simultaneously. The outer end of the sleeve 5 is connected with a ring pipe 7 in a welding way. The support body 4 and the sleeve 5 extend in the radial direction. The column 3, the support body 4 and the sleeve 5 form a set of cooperating mechanisms. The axes of the supporting bodies 4 and the axes of the sleeves 5 of the same set are distributed on the same straight line. In this embodiment, there is a gap between the inner wall of the sleeve 5 and the outer wall of the support body 4. In the present embodiment, the lumen of the cannula 5 forms a space for accommodating the support body 4, and forms a space for deforming the support body 4. The heated diameter of the support body 4 is still smaller than the inner diameter of the sleeve 5.
The outer end of the supporting body 4 of the embodiment can move in the inner cavity of the sleeve 5, and a gap is formed between the outer end of the supporting body and the outer wall of the ring pipe 7, so that the local stress between the inner end of the supporting body 4 and the support column 3 is eliminated, the connection reliability between the inner end of the supporting body 4 and the support column 3 is improved, and the welding fracture is prevented. In addition, the local stress between the outer end of the sleeve 5 and the ring pipe 7 is eliminated, the connection reliability between the outer end of the sleeve 5 and the ring pipe 7 is improved, and the welding fracture is prevented.
Because a gap is formed between the inner wall of the sleeve 5 and the outer wall of the support body 4, the heat transfer between the sleeve 5 and the support body 4 is reduced, the temperature difference between the sleeve 5 and the ring pipe 7 is reduced, and the temperature difference between the support body 4 and the support column 3 is also reduced, so that the local stress of two connecting parts is further reduced, and the connecting reliability is further improved.
In this embodiment, the gap between the inner wall of the sleeve 5 and the outer wall of the support body 4 can be set to be smaller, and the specific size of the gap can be set according to actual needs.
In the present embodiment, the support body 4 is a rectangular tube. In other alternative embodiments, the support body 4 may have other shapes, for example, the support body 4 may be a rectangular tube, a circular tube, a channel, an i-beam, an H-beam, a T-beam, or a combination of at least two of the above different structures. For example, the support body 4 may be a combination of channel steel and i-steel.
In the present embodiment, the number of the branch pipes 8 is at least two, and at least two branch pipes 8 are spaced apart in the circumferential direction. For example, the number of branch pipes 8 is four, five, six, seven or eight, etc. The at least two branch pipes 8 may be uniformly distributed or non-uniformly distributed.
In the present embodiment, the number of the struts 3, the support body 4, and the sleeves 5 is at least two, and at least two struts 3, support bodies 4, and sleeves 5 are spaced apart in the circumferential direction. For example, the number of struts 3, supports 4 and sleeves 5 is four, five, six, seven or eight, etc. The at least two struts 3, the support body 4 and the sleeve 5 may be distributed uniformly or non-uniformly. The pillars 3, the supporting bodies 4, and the sleeves 5 may be arranged alternately with the branch pipes 8 in the circumferential direction, for example, the branch pipes 8, the supporting bodies 4, the branch pipes 8, and the supporting bodies 4 may be arranged in this order in the circumferential direction.
In other alternative embodiments, the number of struts 3 may be greater than the number of support bodies 4 and sleeves 5.
It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments.
