Abstract

The utility model relates to an internal guiding type vertical lime kiln with a kiln core for guiding wind direction and material stream. A column-shaped kiln core with a conical upper cap is arranged between a calcination belt and a cooling belt of the vertical lime kiln, and the upper part of the kiln core is a burning chamber and the lower part is a ventilation chamber. The ventilation chamber is communicated with an air intake through a bustle pipe, and the lower part of the burning chamber is communicated with a combustion nozzle and the upper part is provided with a fire spraying path. The utility model has the advantages of even ventilation and little resistance in the kiln, low effective height, small motive power, strong fuel applicability, simple operation and good labour condition, and is suitable for the building industry, the metallurgy industry and the chemical engineering industry.

Description

A kind of internal guiding type lime vertical kiln

The utility model relate to a kind of have guides wind to the internal guiding type lime vertical kiln of guiding materials flow kiln core.

General nature airy common lime shaft furnace, in order to adapt to natural ventilation, the draft features of limited can only be used the boulder lime stone, cause coal consumption to increase, and output is not high.The common mechanical shaft furnace because of virtual height is big, needs to use high pressure blower, and power consumption is big, and bigger mechanical vertical kiln is bigger because of diameter again, has the inhomogenous shortcoming of kiln ventilation.The energy-saving lime shaft kiln of promoting in medium and small lime industry in recent years, adopt rational vase-shaped kiln type, increased the bottom mechanical ventilation, and changed flat grate into the umbrella shape grate, obtained energy-saving effect, but the weak point of this kiln is: because of the blast inlet useful area is little, the power ventilation effect is not remarkable, needs the draft of top chimney, and can only use solid fuel, only be adapted to produce daily 50 tons to 69 tons little kiln, also need artificial logical ash, labor condition is poor.

The purpose of this utility model be to overcome the deficiencies in the prior art and provide that a kind of kiln ventilation is even, resistance is little, virtual height is low, power is little, fuel tolerance is strong, simple to operate, labor condition good, product category is complete internal guiding type lime vertical kiln.

The purpose of this utility model is achieved in that by common single thorax lime shaft kiln and constitutes, between the calcining zone of lime shaft kiln and cooling zone, a cylindrical kiln core that has the circular cone loam cake is set, the kiln core is made up of two portions up and down, top is the combustion chamber, the bottom is the ventilating chamber, the ventilating chamber communicates with blast inlet by bustle pipe, and the bottom, combustion chamber is chewed with burning and communicated, top is provided with the flame road; The kiln core can be arranged on the supporting leg, and the outside kiln wall in ventilating chamber is provided with thermometer hole, and the flame road is inner to communicate with the kiln core, and the outer end places kiln wall refractory brick, and communicates with peep hole.

It is even to the utlity model has kiln ventilation, resistance is little, virtual height is low, power is little, fuel tolerance is strong, simple to operate, labor condition is good, the advantage that product category is complete, equipment is simple, cost is low, can use solid, gas or liquid fuel, also can use cheap broken coal, the common shaft furnace that can replace natural ventilation, be widely used in building trade, good energy-conserving effect, can also replace gas blower with induced draft fan, be used for the chemical industry that needs reclaim carbon dioxide, can the lower induced draft fan of applying pressure, to cut down the consumption of energy, use coal dust simultaneously, when gas or liquid fuel, can produce highly active metallurgy lime, satisfy steel-making or chemical industry needs high quality lime; Can also produce 3 to 9 centimeters little lump lime, use, improve the utilization ratio of lime without broken direct-furnish steel melting furnace, furnace of calcium carbide.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1, the utility model is made of common single thorax lime shaft kiln, between the calcining zone of lime shaft kiln and cooling zone, a cylindrical kiln core 1 that has the circular cone loam cake is set, the kiln core is made up of two portions up and down, top is the combustion chamber, and the bottom is the ventilating chamber, and the ventilating chamber communicates with blast inlet 2 by bustle pipe 9, the bottom, combustion chamber is chewed 3 with burning and is communicated, and top is provided with flame road 4.Kiln core 1 can be arranged on the supporting leg 5.The outside kiln wall in ventilating chamber is provided with thermometer hole 6.

When using solid fuel, coal mixes the back and is packed into by the top kilneye with Wingdale, when when coal dust, gas or the liquid fuel, need join a spot of wind and chew by burning and send into the kiln core, sprays in the Wingdale through the flame road.

The flame road is established 6 to 12 according to the big I of kiln, is the radial calcining zone that is evenly arranged in, and flame road Section Design is towering shape or semicircle, and Open Side Down.4 the inners, flame road communicate with the kiln core, and the outer end places kiln wall refractory brick, and communicates with peep hole 7.Can observe the fuel combustion situation by peep hole.

Through cooled lime, unload in bulk cement truck by groove 8.
