Abstract
The utility model provides a magnesia powder light burning shaft kiln. A hearth of the magnesia powder light burning shaft kiln is in an urn shape, the diameter of the middle cylindrical section is large, the upper section and the lower section gradually contract to form a truncated regular cone and a truncated reverse cone respectively, vertical sections are arranged on an upper opening of the hearth and a lower opening of the hearth respectively, and lining bricks include a layer of inner lining clay bricks and a layer of outer lining red bricks. According to the magnesia powder light burning shaft kiln, ores which are filled into the magnesia powder light burning shaft kiln can turn in the downward moving process, angles and positions of the ores are changed so that the ores can be uniformly burnt through, and therefore flame and smoke can be conveniently held together, the temperature in the kiln can be raised, the sintering speed can be increased, fuel consumption can be lowered, the sintering effect can be improved, magnesium oxide blocks can not occur, the percentage of MgO in light-burnt powder can be larger than or equal to 85%, the quality percent of pass can be improved, the yield of the kiln can be greatly increased, and the yield of the magnesia powder light burning shaft kiln is increased to 100-110t per day from 60t per day. Meanwhile, the construction cost of the shaft kiln can be effective reduced and economical benefits are improved.
Description
Technical field
The utility model belongs to industrial kiln field, relates in particular to a kind of shaft furnace for light-burning magnesium powder.
Background technology
At present, the domestic shaft furnace for light-burning magnesium powder is mainly to be built by laying bricks or stones and formed by lining brick, and bottom arranges burner, the middle burner hearth that forms splendid attire and calcined ore.Lining brick generally adopts three-decker, and outer kiln wall is that common brick, intermediate layer are clay brick, and liner working lining is magnesia brick.And the shape of burner hearth is elongated cylinder.This version exists great defect: the one, because burner hearth is cylinder, after loading of kiln, ore is calcining and parallel moving down in discharging process, residing position is constant all the time, extruding cannot be overturn mutually, therefore be difficult for grilling thoroughly, in product, have the raw piece of magnesia, light burnt powder MgO >=75%, causes product magnesia quality defective.The 2nd, this shaft furnace does not hold together fire, burns till efficiency low, adopts semi-automatic one direction discharging in addition, causes the output of every kiln every day to only have 60t.The 3rd, adopt three layers of lining brick, especially interior magnesia brick lining price is more expensive, and brick is short easily to come off, and has increased and has built cost by laying bricks or stones.
Summary of the invention
It is good that the utility model aims to provide a kind of sintering effect, and production efficiency is high, can improve and burn till quality and stove output, reduces the light-burning magnesium powder shaft furnace of building and burn till cost by laying bricks or stones.
For this reason, the solution that the utility model is taked is:
A shaft furnace, comprises burner and by lining brick, is built by laying bricks or stones the burner hearth forming, and it is characterized in that, described burner hearth is " urn " shape, middle circle shell of column diameter is large, upper and lower two sections gradually in the truncate normal cone body of harvest and truncate inverted cone, burner hearth upper and lower opening is partly provided with vertical section.
Described lining brick is by liner clay brick and outer lining common brick is two-layer forms.
The beneficial effects of the utility model are:
Because the utility model has changed burner hearth into " urn " shape broad in the middle, two is little by cylinder, can make on the one hand the ore packing in descending process, occur upset, change ore angle and position, be conducive to ore uniform well-burnt; " urn " shape burner hearth is conducive to hold together flame and flue gas on the other hand, improve kiln temperature, accelerate the speed of burning till, when relatively reducing fuel consumption, improve sintering effect, avoid occurring the raw piece of magnesia, make light burnt powder MgO >=85%, improve up-to-standard rate, and can greatly improve shaft furnace output, make light-burning magnesium powder shaft furnace output by within 60t/ days, being increased to 100-110t/ days.Meanwhile, owing to changing three-decker lining brick into double-layer structure, lengthen the length of clay brick, extend kiln service life, and cancelled the higher magnesia brick of price, thereby can effectively reduce shaft furnace, build cost by laying bricks or stones.
Accompanying drawing explanation
Fig. 1 is light-burning magnesium powder shaft furnace section of structure.
In figure: burner hearth 1, clay brick 2, common brick 3, burner 4.
The specific embodiment
As seen from Figure 1, light-burning magnesium powder shaft furnace monnolithic case is a cylindrical shape, is to adopt lining brick to build by laying bricks or stones to form, and in the bottom of kiln body, is provided with burner 4.The utility model one is to have changed reason common brick 3, clay brick 2, three layers of lining brick structure of magnesia brick into clay brick 2, common brick 3 double-layer structures, has cancelled magnesia brick working lining, and has strengthened the length of clay brick 2, adopts the clay brick 2 that length is 400mm.The 2nd, by the shape of burner hearth 1 by original cylindrical having changed into " urn " shape.Whole burner hearth 1 is divided into 5 sections, upper and lower opening is partly respectively equipped with a bit of vertical section, mid portion is cylindrical section, vertical connecting section and cylindrical section have respectively one section of tilting section, middle circle shell of column diameter is large, and upper and lower two sections of tilting sections are received in gradually, and one section of truncate normal cone body is formed at top, one section of truncate inverted cone is formed at bottom, thus " urn " shape cylindrical shell that in the middle of whole burner hearth 1 is formed, bulge is large, two open ends is little.
Claims (3)
1. a light-burning magnesium powder shaft furnace, comprises burner and by lining brick, is built by laying bricks or stones the burner hearth forming, and it is characterized in that, described burner hearth is " urn " shape, middle circle shell of column diameter is large, upper and lower two sections gradually in the truncate normal cone body of harvest and truncate inverted cone, burner hearth upper and lower opening is partly provided with vertical section.
2. light-burning magnesium powder shaft furnace according to claim 1, is characterized in that, described lining brick is by liner clay brick and outer lining common brick is two-layer forms.
