Technical field
Production of toluene diisocyanate field is the utility model is related to, more particularly to a kind of evaporation drying machine stuffing-box.
Background technology
Continuous vacuum drying technique is one of main technique of current industrialization recovery toluene di-isocyanate(TDI), and this technology is
Tar toluene di-isocyanate(TDI) mixed liquor is entered into evaporation drying machine by flash valve, under high temperature condition of high vacuum degree, passes through drying
Toluene di-isocyanate(TDI) is isolated in machine inner main axis and the stirring evaporation of cleaning axle opposite direction rotating, and tar residue is dried to be flowable
Discharged after particle.Stirring by the use of master/cleaning axle and fuselage barrel using three-level filler as sealing, filler packing is loaded on and filled out
To expect in letter, when drying machine is run, master/cleaning axle is axially and longitudinal all by larger torsional forces during tar is ground in scraping,
In grinding, rocking for some strength occurs in master/cleaning axle, periodically rocks so that bolt used in stuffing-box fixation is easily made
Into fracture, filler packing sealing effectiveness is influenceed, causes equipment damage, has a strong impact on the operation of evaporation drying machine.For above-mentioned feelings
Condition, a kind of evaporation drying machine stuffing-box can be designed to solve the above problems.
Utility model content
The purpose of this utility model is that to solve the above problems and provides a kind of evaporation drying machine stuffing-box.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of evaporation drying machine stuffing-box, including body and the cylinder for being fixedly mounted on the body side, the cylinder
Body is internally provided with rotating shaft, and the rotating shaft side is provided with packing, and the packing upper end is provided with stuffing-box, the stuffing-box with
The cylinder junction is additionally provided with solder joint, and the stuffing-box side is additionally provided with bolt.
In order to further improve the practicality of evaporation drying machine stuffing-box, the rotating shaft includes main shaft, cleaning axle.
In order to further improve the practicality of evaporation drying machine stuffing-box, the packing is enclosed on the rotating shaft side and institute
State the junction of cylinder.
In order to further improve the practicality of evaporation drying machine stuffing-box, the stuffing-box is enclosed on the packing lateral surface
On, the junction of the stuffing-box outer surface and the cylinder be welded as a whole the number of welds at least one, uniformly point
Cloth is in the junction of the stuffing-box and the cylinder.
In order to further improve the practicality of evaporation drying machine stuffing-box, the bolt uses high-strength bolt, the spiral shell
Bolt lower end extend into the inner barrel through the stuffing-box, and the stuffing-box is fixed by the bolt and the cylinder to be connected
Connect.
Beneficial effect is：The utility model compared with prior art, by by the cylinder of evaporation drying machine and institute
State stuffing-box to be welded and fixed, the bolt on the stuffing-box can be made not to be broken, make so as to extend the packing
With the life-span, the sealing of evaporation drying machine is fully ensured that, the stuffing-box, which is completely fixed, advantageously reduces evaporation drying owner/clear
The longitudinal direction of clean axle is rocked, and ensures the normal operation of twin shaft.
