Abstract
The utility model relates to a device for sealing a gap between an external heating carbonization furnace product channel and a furnace end tube sheet. The device is a seal cover made of a heat-resistant soft material; openings are formed in the two ends of the seal cover; a flange edge and a compression ring are mounted at one end of the seal cover, and an elastic shroud ring is mounted at the other end thereof. According to the utility model, one end of the device is connected with a flange of the tube sheet through the compression ring, and the other end of the device is arranged on the product channel by the elastic shroud ring in a sleeving manner; as the soft material is adopted, enlarged space is provided for deformation and shrinkage of the product channel, and the problem about damage to seal between the product channel and the tube sheet can be effectively solved. The device is simple in structure, practical and easy to implement.
Description
Technical field
The utility model relates to Activated Carbon Production equipment technology field, specifically, is the tightness system of a kind of external heat charring furnace product channel and burner tube sheet gap location.
Background technology
External heat charring furnace product channel and the sealing of burner tube sheet gap location at present adopts filling type sealing material, mostly be hard sealing material, because temperature variation in stove is larger, can cause that product channel is flexible, distortion, thereby sealing material is formed to considerable influence, cause poorly sealedly herein, occur gas leakage, the system that affects is normally moved.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model proposes the software tightness system of a kind of external heat charring furnace product channel and burner tube sheet gap location, solve under the condition of high temperature due to product channel distortion is flexible and stop, the destruction of driving that filling type sealing material is caused cause poorly sealed, the problem of system cisco unity malfunction.
For achieving the above object, the utility model by the following technical solutions: this device is to adopt the seal closure made of high temperature resistant software material, seal closure both ends open, flange is equipped with in one end, the other end is equipped with elasticity garter spring.
The utility model tightness system one end is connected with tube sheet flange, and the other end is contained on product channel with elastic cuffs ring set, and owing to adopting soft material, to product channel, distortion is shunk provides the space of strengthening, and can effectively solve seal break-off problem.The utility model is simple in structure, and practicality is easy to realize.
Accompanying drawing explanation
Accompanying drawing is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure: on tube sheet 1, be equipped with ring flange, high temperature resistant software seal closure 4 is connected with tube sheet 1 flange with one end of flange, and the other end is sleeved on product channel 2, fixing by elasticity garter spring 5.When stretching, be out of shape when product channel 2 producing in tubesheet holes, high temperature resistant software seal closure can be with the dilatation motion of product channel, the dilatation of product channel can not produce and destroy high temperature resistant software seal closure, thereby has reached hermetic effect, and assurance system is normally moved.In embodiment, for guaranteeing that flange is connected with the reliable of tube sheet 1, be also equipped with pressure ring 3, flange is fixed on tube sheet 1 by pressure ring 3.
Claims (2)
1. external heat charring furnace product channel and burner tube sheet clearance sealing device, it is characterized in that, this device is the seal closure (4) that adopts high temperature resistant software material to make, seal closure both ends open, flange is equipped with in one end, and the other end is equipped with elasticity garter spring (5).
2. external heat charring furnace product channel according to claim 1 and burner tube sheet clearance sealing device, is characterized in that, the flange of high temperature resistant software seal closure (4) is also equipped with pressure ring (3).
