The invention solves the problems of poor strength of bearing bricking-up structure of the upper tank, easy damage, largely shielding heating to the lower part of a reduction tank, uneven heating of materials in the tanks, small flowing section of smoke in the furnace, uneven temperature in the furnace, and the like.
Description
Technical field
The present invention relates to double jar of magnesium reducing furnace of smelting field of nonferrous metal, particularly relate to a kind of supporting construction for upper layer tanks of double row tank magnesium reducing furnace, flow and being heated evenly property of tank body, improve material reduction output capacity in the jar in order to improve inner flue gas of the stove; Increase the stability of upper strata jar supporting masonry, the service life of improving reduction furnace.
Background technology
Upper strata jar supporting structure is the important component part of double jar of magnesium reducing furnace, it mainly acts on is at reduction furnace internal support magnesium-reduced tank body, guarantee tank body thermally equivalent at high temperature, make jar interior material under the temperature of technique initialization, finish reduction reaction smoothly, excessive until magnesium steam to the condensing zone crystallization.Magnesium-reduced technological requirement upper strata jar supporting structure intensity is good, can resist and take on jar thrust that operation brings, and also will dwindle supporting structure as far as possible being heated of tank body covered under the indeformable condition of tank body guaranteeing.
Existing supporting construction for upper layer tanks of double row tank magnesium reducing furnace, all adopt common standard type refractory brick to build by laying bricks or stones, shortcoming with following several respects: 1, structural strength is poor, very easily layering in taking on jar operating process, comes off even topples over, and causes the tank body distortion until the ordinary production that influences reduction furnace; 2, supporting masonry section is big, has seriously covered the heating surface of tank body bottom, causes jar interior material inequality of being heated, and has reduced magnesium-reduced output capacity; 3, owing to double jar layout feature, spacing is little between lower floor's tank body and the upper strata jar supporting masonry, has reduced the cross section of flue gas circulation, causes the flue gas circulation not smooth, has worsened the working of a furnace, has reduced the heat capacity of stove; 4, because the supporting masonry has occupied bigger burner hearth area, can't stay equably and establish the lower furnace exhaust smoke hole, cause the interior temperature dead angle of stove many, furnace temperature is inhomogeneous, has seriously influenced a jar interior material reduction output capacity.
Summary of the invention
The present invention be exactly to provide in order to solve the problems of the technologies described above a kind of supporting construction for upper layer tanks of double row tank magnesium reducing furnace, purpose be solve upper strata jar supporting masonry structure intensity difference, fragile, to a reduction jar bottom be heated cover big, jar in the material problems such as inequality, the inner flue gas of the stove flow area is little, furnace temperature is inhomogeneous of being heated.
In order to solve the problems of the technologies described above, the present invention is achieved in that a kind of supporting construction for upper layer tanks of double row tank magnesium reducing furnace, is made of top holder jar brick and lower base checker brick; Be provided with reinforcement in the middle of the top holder jar brick, the side of top holder jar brick is for being provided with the spill guide face; The lower base checker brick are the double type that is connected by base, and the base of lower base checker brick is provided with smoke evacuation grid hole; Top holder jar brick and lower base checker brick are that brickwork joint is connected or special form brick connects, and brickwork joint connects or the special form brick connection is that mother-son mouth adds refractory wass and is connected.
A described top holder jar brick is a saddle type.
The cross section of described reinforcement is any one in ellipse, rectangle, circle or the polygon.
Described spill guide face is any one in lonely shape curved surface, lonely phase cross surface, obtuse angle phase cross surface or the right angle intersection face.
The shape in described smoke evacuation grid hole is any one in square, rectangle, circle or the polygon.
Described female mouth is located at the bottom of top holder jar brick.
Described rim of the mouth is located at the top of lower base checker brick.
Described mother-son mouth shape is any one in semicircle, circular arc, trapezoidal, rectangle or the triangle.
Supporting construction for upper layer tanks of double row tank magnesium reducing furnace of the present invention has the following advantages:
1, be special form brick entire combination structure owing to what adopt, the masonry structure of being formed has been cancelled most of construction joint, and between the special form brick all with the mutual bond of the form of mother-son mouth, so good integral strength, can at high temperature resist the lateral thrust that reduction furnace forms well in taking on jar operation, help prolonging the service life of whole stove.
2, designed top holder jar brick and lower base checker brick brick body cross section are little, but the fulcrum to tank body is many, has both dwindled the covering of tank body bottom heating surface, and can reduce the tank body temperature distortion again, it is more even to make that a jar interior material is heated, and helps improving the reduction output capacity of jar interior material.
3, owing to the sidepiece at supporting construction for upper layer tanks of double row tank magnesium reducing furnace has adopted the design of spill guide face, effectively enlarge burner hearth flue gas flow area, improved the working of a furnace, can improve the heat capacity of reduction furnace, and then improved the production capacity of reduction furnace.
4, because the lower base checker brick have the smoke evacuation function, it is more even that reduction furnace furnace bottom cigarette hole is provided with, and eliminates temperature dead angle in the stove effectively, and whole fire box temperature uniformity coefficient is obviously improved, and then material reduction output capacity in the jar of raising reduction furnace.
