Abstract
The combined cover for chlorination furnace consists of at least two parts with stepped contact surface in between, and has stuffing box filled with elastic refractory material to form sealing cushion between the two parts, fastening screws and fastening ribbed plate with filled slurry filler. The steel cover casing is provided with circumferential ribs, radial ribs and radial refractory layer ribs. The present invention is used for large chlorination furnace with large and heavy cover, and has high sealing performance, high rigidity, less deformation, long service life and other features.
Description
Technical field
The present invention relates to the preparation of titanium tetrachloride, relate in particular to the chlorination furnace bell.
Background technology
Technical development along with titanium industry, chlorination process is produced the key equipment of titanium tetrachloride---and chlorination furnace is tending towards maximizing, the chlorination furnace diameter has developed into Φ 1600mm～Φ 5000mm now, existing brickwork technology and equipment manufacturing technology is the incompatibility development need, the general taper that adopts of chlorination furnace bell prior art, in build refractory materials, one-piece construction.This technology causes in bell transportation, lifting and installation process, the bell easy deformation, the easy crack of flame retardant coating or come off, work-ing life is short, generally will scrap less than 2 months, because scantlings of the structure and weight are bigger, transportation and lifting difficulty are made upset difficulty in steel part and casting flame retardant coating and the use, therefore production efficiency is low, maintenance labour intensity height, the cost of equipment maintenance height, and also frequent maintenance is unfavorable for environmental protection.
For solving this class problem of industrial appearance, Chinese patent application CN94225851 " assembly type electric arc furnace bell ", the refractory lining of this bell is to give the packaging assembly that clamp dog is combined into one by three blocks of refractory concretes at least.Chinese patent application CN95204354 " pit kiln bell " and Chinese patent application CN90207844 " pit kiln bell " propose movable pit kiln bell, are constituted by several tegillums, and little cap body is rack (shape) structure.These patented technologies all have its industry specific aim, can not be used for chlorination furnace.
Summary of the invention
The object of the present invention is to provide a kind of chlorination furnace built-up type bell, yielding to solve large-scale chlorination furnace bell, flame retardant coating easily comes off, and starts shipment, problems such as dismounting, upset difficulty, thereby improves service life of equipment and enhance productivity, and helps environment protection.
Technical scheme of the present invention is under the situation that takes into full account bell rigidity, reasonably bell being designed to be at least two partly forms, every part contact surface each other is the step type contact surface, form stuffing box between the two step type contact surfaces, fill out among the stuffing box with elastic fire resisting material and form gasket, contact surface top also adopts bolted to connect, and fills the pulpous state filler between fastening gusset, and these measures can solve the sealing problem with the bonding surface behind the bell subdivision.
Bell box hat upper surface is provided with circumferential stiffening web and radially radial stiffening web to improve the rigidity of bell each several part, and bell is not yielding.Bell box hat lower surface is provided with the flame retardant coating stiffening web of network radial arrangement, makes that flame retardant coating is not easy to crack, difficult drop-off.
The invention solves because after the chlorination furnace maximization; the scantlings of the structure of bell and weight increase the problems that cause; the present invention has good seal performance; the rigidity height; be out of shape for a short time, refractory masses does not come off, and transportation and lifting are convenient; easy to assemble, characteristics such as long service life, production efficiency height, environment protection are good.
