Abstract
The invention belongs to the manufacturing technology field of conveying pipelines, and particularly relates to an ore pulp conveying pipeline which is high temperature and high pressure resistant and safe and stable in performance. Concretely, according to the ore pulp conveying pipeline, two buffering tanks are installed at the two places of corner bent pipes respectively in the original ore pulp conveying pipeline according to the defect that the corner bent pipes at the two places in a traditional ore pulp conveying pipeline are prone to being abraded and must be replaced at every 45 days, and the two buffering tanks are used for replacing the corner bent pipes, impact of ore pulp in the process of flowing through the buffering tanks is reduced, and buffering gaskets and buffering pillars additionally arranged in the buffering tanks can bear abrasion for a longer time, and the ore pulp conveying pipeline which only needs to be replaced three times in a year and is composed of the buffering tanks is obtained. Safe performance is good in the operation process of the ore pulp conveying pipeline, and besides the ore pulp conveying pipeline is continuous and stable in the operation process.
Description
Technical field
The invention belongs to a kind of preparing technical field of conveyance conduit, be specifically related to a kind of high temperature high voltage resistant, the ore pulp delivery duct that wear-resistant and performance safety is stable.
Technical background
In alumina producing flow process, the flash vessel of digestion workshop is interconnective, and be the ore pulp that delivery temperature is greater than 200 ℃ between interconnective ore pulp delivery duct, and when operation, the pressure that will bear in pipeline can reach 68 kilograms of above/m
2, minimum also have a 2 kilograms/m
2.At present, in existing alumina production line, in above-mentioned digestion workshop, between each flash vessel, interconnective ore pulp delivery duct has two place's corner bend pipes, in conveyance conduit, ore pulp in flow process because flowing velocity is too fast, add under the effect of high temperature and high pressure, the degree that two corner bend pipes of conveyance conduit are worn is also significantly accelerated.Because the pressure that will bear when operation in conveyance conduit is excessive, once conveyance conduit is blasted, consequence is hardly imaginable.So the ore pulp delivery duct ubiquity of digestion workshop great potential safety hazard.In order to guarantee safe production; current alumina producing enterprise must stop production and change the ore pulp delivery duct between flash vessel about 40 days; and approximately 2,000,000 yuans of expenses that each ore pulp delivery duct of changing of group needs; among 1 year, change 8～9 times, altogether need to spend approximately 2,000 ten thousand yuans, add one group of ore pulp delivery duct of every replacing; need approximately 24 hours consuming time; need to shut down every year 8～9 days, the loss producing is also huge, has increased virtually cost of production.
Summary of the invention
Object of the present invention be exactly overcome the deficiency of the said equipment and provide brand-new a kind of in alumina production line between each flash vessel of digestion workshop both wear-resistant, high temperature high voltage resistant, can realize the ore pulp delivery duct of the permanent and safety and stability of operation.Specifically comprise: according to two place's corner bend pipes in traditional ore pulp delivery duct, because easily wearing and tearing, probably about 40 days, must change, the present invention has replaced corner bend pipe and two knock out drums has been installed in two place's corner pipe bent position of original ore pulp delivery duct respectively, ore pulp has reduced scouring abrasion power while passing through knock out drum in flowing, and the cushion pad of setting up in knock out drum and bumper post can bear more permanent wearing and tearing, realized the ore pulp delivery duct that only need more exchange treaties and be formed by knock out drum for 3 times in 1 year, not only Safety performance is good when operation for ore pulp delivery duct, and continual and steady.
The present invention is achieved through the following technical solutions:
1, an ore pulp delivery duct, in technological scheme, its structure is comprised of pipeline (1) and two knock out drums (2).
2, a kind of ore pulp delivery duct, the structure of pipeline in technological scheme (1) be in tank preceding pipeline, tank after pipeline and tank pipeline form, the two, front and back in every pipe joint road is all provided with flange (3), the length that pipeline (1) couples together is to come layout to set up according to produced on-site is required, and the bore specification of pipeline (1) conforms to the import and export of knock out drum (2).
3, an ore pulp delivery duct, the can body shape of knock out drum in technological scheme (2) is a circular arc column type; The structure of can body is: in tank deck center, open an ore pulp import (4), ore pulp import (4) is provided with a flange (3), 1/3～2/3 place making progress from bottom at can body limit wall opens an ore pulp outlet (5), and ore pulp outlet (5) arranges the flange (3) of equally; At the bottom of tank, set up cushion pad (6), the layout of cushion pad (6) in tank is that its thickness extends to 15～20cm along can body from pot bottom always; In the middle of cushion pad (6), set up the bumper post (7) of up big and down small, a shape picture handstand isosceles trapezoid; Cushion pad (6), bumper post (7) and knock out drum (2) are as a whole by being welded to connect into.
4, an ore pulp delivery duct, the connecting means of pipeline in technological scheme (1) and knock out drum (2) is: the upper flange arranging of ore pulp import (4) of a head flange of tank preceding pipeline and vertical buffering tank (2) connects; The flange that the ore pulp outlet (5) that in tank, a head flange of pipeline and vertical buffering tank (2) can body limit wall are opened arranges connects, and in tank, the other end flange of pipeline is to connect with the upper flange arranging of ore pulp import (4) of Horizontal buffer tank (2); After tank, pipeline is to connect with the upper flange arranging of ore pulp outlet (5) of Horizontal buffer tank (2).
Tool of the present invention has the following advantages:
1, the two place's corner bend pipes in ore pulp delivery duct that come proposed by the invention are installed respectively two knock out drums and are replaced the method and measure of corner bend pipe unique, practical, and easily implement.
2, by application the present invention; while allowing ore pulp flow operation in pipeline, the wearing and tearing of equipment are dropped to minimum degree; one is only needs and shut down changes ore pulp delivery duct approximately 3 times thus, and change when of the present invention than the ore pulp delivery duct that in the past had a corner bend pipe more easily, the time is shorter.
3, by application the present invention, the ore pulp delivery duct being formed by knock out drum, make to produce safer, more stable, more convenient, accurate, quick while carrying out that Safety performance detects.
4, suppose the aluminium oxide of 500,000 tons of one group of flash vessel annual outputs, produce approximately 1400 tons of aluminium oxide finished products every day, by application the present invention, within 1 year, only need to change 3 ore pulp delivery ducts, only lose: 3 days * 1400 tons=4200 tons; And 1 year needs of traditional ore pulp delivery duct are changed 8～9 times, loss reaches: 8～9 days * 1400 tons=11200～12600 tons.
5, by application the present invention, not only significantly saved equipment investment expense, also can make the running of alumina production line high speed and safety and stability.
6, the present invention also can apply widely on the ore pulp delivery duct of every field.
