Technical Field
The utility model belongs to the technical field of graphite radiator, concretely relates to seal structure of graphite heat exchanger.
Background
The graphite heat exchanger is a heat exchanger made of graphite for a heat transfer assembly. The graphite heat exchanger has good corrosion resistance, a heat transfer surface is not easy to scale, the heat transfer performance is good, the graphite heat exchanger is mainly used for corrosive media such as hydrochloric acid, sulfuric acid, acetic acid and the like, an original inner pipe and an original outer pipe are sealed through sealant, when the product is used, the inner pipe or the outer pipe made of graphite materials can expand with heat and contract with cold due to temperature change, the inner pipe or the outer pipe is broken or cracked, and therefore the sealing structure of the graphite heat exchanger is provided.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a seal structure of graphite heat exchanger to it is sealed through sealed glue between former inner tube and the outer tube to provide in solving above-mentioned background art, can expend with heat and contract with cold because of temperature variation during the product use, breaks or spalls the inner tube or the outer tube of graphite material.
In order to achieve the above object, the utility model provides a following technical scheme: the sealing structure of the graphite heat exchanger comprises an outer tube, wherein a mounting groove is formed in the surface of the bottom end of the outer tube, an inner tube is arranged on the inner side of the mounting groove, a groove is formed in the outer side of the inner tube, and a sealing ring is arranged on the inner side of the groove.
Preferably, the inner pipe is connected with the mounting groove in a sliding mode, and the section of the mounting groove is circular.
Preferably, the number of the grooves formed in the outer side of one end of the inner pipe is two, and the number of the sealing rings is two.
Preferably, the section of the bottom end of the mounting groove is of a horn-shaped structure, and a gap is reserved between the inner pipe and the inner side of the mounting groove.
Preferably, the section of the sealing ring is circular, and the outer side of the sealing ring is attached to the outer side surface of the inner pipe.
Compared with the prior art, the beneficial effects of the utility model are that:
through sealed glue between former inner tube and the outer tube sealed, can expend with heat and contract with cold because of temperature variation during the product use, pull the inner tube or the outer tube of graphite material bad or spalling, it is sealed through the sealing washer now, can gapped avoid expend with heat and contract with cold's effect between the interior outer tube, can slide each other moreover, mutual displacement is very little be unlikely to damage the sealing washer, easy dismounting, this equipment is small, original bottom is the toper, present bottom only open a horn mouth can.
