Description
Technical field
A kind of graphite heater tube sheet is the utility model is related to, belongs to experimental branch line equipment technical field.
Background technology
In production process of viscose fiber, the temperature of acid bath, influences for wire strip forming in spinning process and dyeing quality
Greatly, the viscose rayon of uniform quality is produced, the temperature of acid bath must keep stable.Since acid bath flows through spinning in the circulating cycle
During silk machine, temperature reduces about 2-4 DEG C, and in the pipeline from heater to spinning-drawing machine, heat also has loss, and temperature about declines 0.5-
1℃.Therefore, acid bath must be heated by heater, according to the internal circulating load of acid bath, distance and the insulation of acid station and spinning workshop
The difference of box seasonal conditions, in the heater, temperature generally improves 3-7 DEG C for acid bath.At present, the heater used in industry has stone
Ink stick heater, graphite tube heater and plate heat exchanger etc., using more for graphite tube heater.Traditional graphite-pipe is
Tube still heater, due to its heat exchange area it is larger, efficient, corrosion-resistant the advantages that, be still used widely, but heater to behaviour
Work, maintenance requirement are higher, and failure rate is higher.
Graphite-pipe Tube Heat Exchanger is mainly formed by housing, tube bank and with both ends tube sheet, restrains both ends heat resistant rubber
Sealing ring is fixed on the tube sheet of both ends lining stone ink, forms flexible integrated structure, wherein, the tube sheet in graphite tube heater is easily
Damage, can influence the stability of whole production technology；Tube sheet is mostly carbon steel line with rubber tube sheet, rubber liner quality once it cannot be guaranteed that or by
Cause line with rubber to damage in other reasons, then the problems such as internal corrosion of carbon steel will soon be fallen, cause perforation by acid bath, and wear
The graphite-pipe for crossing tube sheet and the gum cover for fixing graphite-pipe are fragile.
State knows that office disclosed a kind of Publication No. CN202066408U in 07 day on the 12nd 2011, and patent name is " graphite
The utility model patent of pipe and the sealing structure of tube sheet ", the patent with solve reliability present in existing sealing structure it is poor,
The problem of pressure-resistant relatively low.Seal is sealing ring and gasket seal.The end of graphite-pipe is equipped with the sealing bolt with centre bore,
It is connected through a screw thread between the two.The bottom of graphite tube end internal thread hole is equipped with concave station, and the sealing ring is arranged on the concave station
Between plane and the end of sealing bolt.Pore on tube sheet and counterbore, the head of sealing bolt are equipped between the outer surface of tube sheet
Portion is located in counterbore.The outer surface of tube sheet is equipped with pressing plate, and pressing plate is connected by bolt and nut with tube sheet；Pressing plate is equipped with and opens
Hole.The gasket seal is arranged in counterbore, between the head of sealing bolt and pressing plate.The utility model is mainly used for tubular type
In graphite heat exchanger.
But the device also consolidates there are graphite-pipe and the problems such as poor sealing, do not solve tube sheet yet and easily damage problem.
Utility model content
The utility model aims to solve the problem that prior art problem, and proposes a kind of graphite heater tube sheet.By to rapid wear
The improvement of bad tube sheet, reduces the failure rate of heater, meanwhile, increase tube sheet improves production work to the graphite seal of tube and stability
The stability of skill.
In order to realize above-mentioned technical purpose, following technical solution is proposed：
A kind of graphite heater tube sheet, is arranged on graphite tube heater both ends, including tube sheet body, and tube sheet body is equipped with
Multiple pores, pore pass through chamfered；Sealing device is equipped with the pore, sealing device is fixedly connected with pore inner wall,
The sealing device includes gum cover and the gasket for being arranged on gum cover end, and gum cover is fixedly connected on pore inner wall.
Preferably, the gum cover is tapped trapezoidal gum cover, so both ensure that sealing effect, also ensure that gum cover
What graphite-pipe was fixed is more firm, reduces gum cover and is broken or comes off and causes graphite-pipe the failure such as to come off.
Preferably, the tube sheet body is glass steel material, and glass steel material has strong corrosion resistant, in use
The service life of tube sheet can be extended, ensure the stable operation of production.
Preferably, the gasket seal is lip packing pad.
Using the technical program, that brings has the beneficial effect that：
In the utility model, pore passes through chamfered, removes flash removed, easy to the peace of sealing device and graphite-pipe
Dress；The setting of sealing device, increase tube sheet improve the stability of production technology to the graphite seal of tube and stability；Band internal thread
Trapezoidal gum cover, so both ensure that sealing effect, also ensure that gum cover fixes graphite-pipe is more firm, reduces gum cover and breaks
Split or come off and cause graphite-pipe the failure such as to come off；Tube sheet is glass steel material, and glass steel material has strong corrosion resistant, using
During can extend the service life of tube sheet, ensure the stable operation of production；Gasket seal is lip packing pad, increase sealing
Effect, improves the stability of graphite-pipe；The present apparatus by varying tube sheet material, hole structure and graphite-pipe fixation and sealing
Mode, reduces the various failures of the former common appearance such as gum cover is easily rupturable, graphite-pipe is easy to fall off, ensures the stability of production, reduce
The labor intensity of worker, and then production cost is reduced, improve work efficiency.
