Abstract
The utility model provides a heat accumulator of a rotary kiln, which is a hollow rectangular cylinder, length is about 1/5 of diameter of a kiln body; wherein bottom ends of two adjacent side faces of the heat accumulator are provided with lug holes; four side faces are provided with circular heat accumulation holes which are arranged neatly and have the same size, the opposite side faces have the same hole position, the adjacent side faces have interlaced hole position, diameter of the heat accumulation hole is 5-8 mm; a heat insulation plate is loaded between the heat accumulator and an lug hole; and high-strength wear-resistant castables are poured into the hollow heat accumulator. The heat accumulator of the rotary kiln has the following advantages: heating area of calcined ores is increased, heat in a high-temperature area is fully played, heat loss is reduced, pyrolysis speed is increased, ore calcining effects are increased, yield is increased, coal consumption is reduced, production cost is reduced; equipment investment is small but effectiveness is quick, overall economic, social and environmental benefits are good.
Description
Technical field
The utility model relates to a kind of rotary kiln heat storage, belongs to the energy-saving equipment technical field.
Background technology
At present, in the rotary kiln less than 1300 ℃ of calcining mineral, filling rate is low in the production process; Poor thermal efficiency, coal consumption are higher relatively, and afterbody discharging flue-gas temperature is up to 600～700 ℃; Though the device that kiln also has surplus heat outward and utilizes, heat effect performance in high-temperature region is not enough, and energy can not make full use of; Heat loss is higher, and the calcining effect is general.
Summary of the invention
The purpose of the utility model is to propose a kind of rotary kiln heat storage, specifically is exactly the high temperature section at rotary kiln, by a determining deviation many group heat storages is installed, and increases the calcined ore heating surface area, improves pyrolysis rate, improves output, cuts down the consumption of energy, and reduces production costs.
A kind of rotary kiln heat storage that the utility model proposes, heat storage is installed in through the ear seat on the inwall of rotary kiln, and heat storage is shaped as the rectangle cylinder of hollow, and length is about 1/5 of kiln body diameter; Wherein the bottom of two adjacent side of heat storage is provided with ear seat hole; Four sides all are provided with the identical circular accumulation of heat aperture of marshalling size, but the side position of opening of position, opposite is identical each other, and the side position of opening of adjacent position is interlaced each other, and the diameter of accumulation of heat aperture is 5 ~ 8 millimeters; Thermal insulation board is carried between heat storage and the ear seat, to prevent ear seat melted by heat; High-strength wear-resistant pouring material is poured in the heat storage of hollow.
The advantage of a kind of rotary kiln heat storage that the utility model proposes is: increased the calcined ore heating surface area, improved pyrolysis rate, improved the ore calcination effect, improved output, reduced energy consumption, reduced production cost.The little instant effect of equipment investment, mixed economy, society, environmental benefit are good.

The specific embodiment
A kind of rotary kiln heat storage that the utility model proposes, its structure is as shown in Figure 1, comprises heat storage side 1, accumulation of heat aperture 2 and 3, ear seat hole 4.Heat storage is shaped as the rectangle cylinder of hollow, and length is about 1/5 of kiln body diameter; Wherein the bottom of two adjacent side of heat storage is provided with ear seat hole; Four sides all are provided with the identical circular accumulation of heat aperture 2 or 3 of marshalling size, but the side position of opening of position, opposite is identical each other, and the side position of opening of adjacent position is interlaced each other, and accumulation of heat aperture 2 or 3 diameter are 5 ~ 8 millimeters; Thermal insulation board is carried between heat storage and the ear seat, to prevent ear seat melted by heat; High-strength wear-resistant pouring material is poured in the heat storage of hollow.
The course of work of a kind of rotary kiln heat storage that the utility model proposes:
In the ore calcination process, temporarily be in the heat storage at high temperature section top in the rotary kiln, absorb the heat in the flue gas, along with the rotation of rotary kiln; During the bottom of top heat storage rotation, contact with ore, and imbed in the ore; During this period, heat storage is progressively to the ore release heat, along with the rotation of rotary kiln; Heat storage leaves the bottom, leaves ore, repeats heat absorption again.Heat storage cycle alternation heat absorption like this heat release can drop to flue-gas temperature about 200 ℃ like this, so made full use of the heat in the flue gas of high-temperature region, shortens calcination time effectively, has improved production efficiency.
A kind of rotary kiln heat storage that the utility model proposes has increased the calcined ore heating surface area, has given full play to the heat of high-temperature region; Reduce thermal loss, improved pyrolysis rate, improved the ore calcination effect; Increase output, reduced energy consumption, reduced production cost.
