Description
Technical field
The present invention relates to haydite kiln technical field, relate to a kind of bitubular haydite kiln that is used for preheating and roasting haydite in particular.
Background technology
When utilizing haydite to make cement block, need use the haydite kiln haydite is heated, the haydite kiln furnitures have preheating kiln and two kilns of calcining kiln; Whole haydite kiln and level are certain gradient, from the preheating kiln to calcining kiln and the distance on ground diminish gradually, be provided with the thermal source that is used to heat haydite in the outlet of calcining kiln; The high-temperature flue gas that thermal source produces heats haydite, and temperature is than higher, in 1400 deg.c in the time of the haydite heating; Haydite after fully being heated by this temperature is suitable for making cement block, and the preheating kiln is in the front portion of calcining kiln, and the main flue dust tail gas (600-700 degree centigrade) of coming from calcining kiln that utilizes carries out preheating to haydite; So not only relatively energy-saving and environmental protection; And can prevent that haydite from bursting, and carries out preheating and will get up from the flue dust waste gas utilization that calcining kiln is come to haydite in roasting with the water evaporates in the haydite before roasting; Make haydite before getting into heating, have certain temperature; Also reduced the energy consumption of thermal source, still, existing haydite kiln has following weak point:
In preheating, be heated uniformly in order to make the haydite in the preheating kiln, the preheating kiln is rolling; But because preheating kiln diameter relatively thick (being generally about 2m), only some contacts with high-temperature flue gas to put into the haydite of preheating kiln, and most high-temperature flue gas to contact with haydite; Caused waste; Make that also the preheating of haydite is abundant inadequately, in heating, can produce and burst, can make that also the amount of the haydite that processes in the whole preheating kiln unit interval is few.And existing preheating kiln and calcining kiln, heat preservation effect is good inadequately, and heat scatters and disappears big; Process is measured the temperature of preheating kiln charging aperture 1m place outer wall at 260-280 ℃; The temperature of the flue gas that comes out from the preheating kiln is at 450-480 ℃, wastes more seriously, increased the energy consumption of thermal source.At 650-700 ℃, scattering and disappearing of heat is same bigger apart from the temperature that exports 1m place outer wall for calcining kiln.
Summary of the invention
The objective of the invention is weak point to prior art; A kind of bitubular haydite kiln is provided, when it can guarantee that a large amount of haydites heats in the preheating kiln, is heated evenly; High with the heat exchanger effectiveness of high-temperature flue gas, the heat that can also reduce whole haydite kiln scatters and disappears.
In order to solve the problems of the technologies described above; Technical scheme of the present invention is following: a kind of bitubular haydite kiln; Comprise preheating kiln, calcining kiln, said preheating kiln and calcining kiln are communicated with through transition sealing devices, and preheating holder catch wheel device, preheating gear wheel device and preheating transmission device are installed on the described preheating kiln; Roasting holder catch wheel device, roasting gear wheel device and roasting transmission device are installed on the described calcining kiln; In the end of described calcining kiln the kiln hood cover is installed, described preheating kiln comprises preceding kiln body, is provided with the tubular type raising material unit in the said preceding kiln body.
