Abstract
The utility model discloses a water cold air hole sleeve of a cupola furnace, belonging to the field of cupola furnaces; the technical problem to be solved is to provide a furnace which has simple structure and convenient use, can improve the wind pressure of an inlet, improve the coke combustion of a furnace core and prolong the furnace period; the technical scheme for solving the technical problem is as follows: the cupola water cold air port sleeve comprises an outer sleeve, an inner sleeve and a flange, wherein the outer sleeve is sleeved outside the inner sleeve, the rear end of the outer sleeve and the rear end of the inner sleeve are fixed in a nested mode through the flange, a cavity is formed between the outer sleeve and the inner sleeve, a water inlet and a water outlet are formed in the outer sleeve, cooling water is filled in the cavity, a conical air inlet is formed in the opening of the flange, one side, with a larger conical section, of the conical air inlet is connected with the flange, and the other side, with a smaller conical section; the utility model can be widely applied to the cupola furnace field.
Description
Technical Field
The utility model discloses a water-cooled tuyere sleeve of a cupola furnace, which belongs to the technical field of cupola furnaces.
Background
A cupola furnace is an important device for melting cast iron in casting production, a cast iron block is melted into molten iron and then poured into a sand mold, a sand box is opened after cooling to obtain a casting, the cupola furnace is a vertical cylindrical furnace, air must be blown into the bottom of the cupola furnace in order to increase the combustion efficiency of coke of the cupola furnace, but the technical problem that how to enter air and ensure that an air inlet device is not melted under the condition of high temperature is difficult to solve is generally adopted for cooling by adopting a water cooling mode at an air port, and because the traditional air port is a U-shaped water pipe, the water circulation is not smooth, water in a pipeline is often evaporated by high heat to form steam, and the water circulation cannot be realized.
The wind gap cover among the prior art, it is all copper casting or welding usually, the structure is mostly the flange, the endotheca, the overcoat, the water conservancy diversion water jacket, because casting size deviation is big, cause inside cooling water structure inaccuracy, the fit clearance is easily scurried water or is produced the rivers dead angle greatly between each part, influence the distribution of cooling water in wind gap cover inside, the cooling effect does not reach the requirement, local overheat burnout phenomenon often appears in wind gap cover, lead to wind gap cover life-span significantly reduced, and the inside cooling water structure function singleness of this kind of traditional blast furnace wind gap cover, blast furnace fuel injection mode is single, can't satisfy blast furnace injection fuel's diversified development.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes the defects of the prior art, provides a furnace which has simple structure and convenient use, can improve the wind pressure of the inlet, improve the coke burning of the furnace core and prolong the furnace period.
In order to solve the technical problem, the utility model discloses a technical scheme be: the cupola furnace water cold air port sleeve comprises an outer sleeve, an inner sleeve and a flange, wherein the outer sleeve is sleeved outside the inner sleeve, the rear end of the outer sleeve and the rear end of the inner sleeve are fixed in a nested mode through the flange, a cavity is formed between the outer sleeve and the inner sleeve, a water inlet and a water outlet are formed in the outer sleeve, cooling water is filled in the cavity, a conical air inlet is formed in the opening of the flange, one side, with a larger conical section, of the conical air inlet is connected with the flange, and one side, with a smaller conical section.
The conical air inlet is a telescopic air inlet.
The minimum diameter of the conical section of the conical air inlet is 90 mm.
The outer sleeve, the inner sleeve, the flange and the conical air inlet are made of high-temperature-resistant stainless steel.
The high-temperature resistant stainless steel is 310S stainless steel.
Compared with the prior art, the utility model following beneficial effect has: use high temperature resistant stainless steel, can prevent that the cooling water in the water-cooling jacket from being evaporated for vapor, simultaneously through the toper air intake, can ensure to reach higher wind pressure under the same fan frequency, can the combustion efficiency of effectual improvement wick coke, reduce the oven effect, extension stove period.
Drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1 is an outer sleeve, 2 is an inner sleeve, 3 is a flange, 4 is a cavity, 5 is a conical air inlet, 6 is a water inlet and 7 is a water outlet.
Detailed Description
As shown in fig. 1, the utility model discloses towards cupola water cold wind mouthful cover, including overcoat 1, endotheca 2 and flange 3, 1 cover of overcoat establish at endotheca 2 outsidely, 1 rear end of overcoat and 2 rear ends of endotheca fixed through flange 3 nestification, vacuole formation 4 between overcoat 1 and the endotheca 2, be provided with water inlet 6 and delivery port 7 on the overcoat 1, the inside filling of cavity 4 has the cooling water, flange 3 opening part is provided with toper air intake 5, the less one side of toper cross-section of toper air intake 5 links to each other with flange 3, flange 3 is kept away from to the great one side of toper cross-section, toper air intake 5 is telescopic air intake, the toper cross-section minimum diameter of toper air intake 5 is 90mm, overcoat 1, endotheca 2, flange 3, toper air intake 5 material are high temperature resistant stainless steel, high temperature resistant stainless steel is 310.
The utility model discloses when using, the wind gap is inserted in toper air inlet department, can adjust the size of toper air intake according to the wind gap of equidimension not, water cooling medium is installed in the cavity between overcoat and endotheca additional, can adapt to near high temperature work in wind gap, uses the toper air intake to reach higher wind pressure simultaneously, can improve 28.6% with the wind pressure, and combustion-supporting wind obviously blows into the stove center more easily, improves the burning of stove core coke, and the oven effect reduces, prolongs the furnace period.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
