Abstract
The utility model discloses a rotary kiln body which is appropriate for baking crude ore or extractive powdered ore, etc. The structure of the utility model is that the inside of the kiln body 1 which is provided with a flame-proof and heat-insulating layer 2 is provided with one or more than one stop ring 4. The kiln body of the utility model can double enlarge the fill factor of material inside the kiln, makes the fill factor to achieve to 0.1-0.25, and prolongs the dwell time of staying in the kiln of material. So, the utility model accomplishes the purposes of double enlarging baking production under the conditions of the same volume of the kiln body and the same baking condition, saving energy and decreasing specific investment cost of firing furnace.
Description
Technical field
The utility model relates to a kind of rotary kiln body that is used for roasting tcrude ore and fine ore.
Background technology
In metallurgical production, most of ores all will be through pretreating process such as high-temperature roastings.For obtaining high-quality roasted product, the roasting time of material in kiln is a key factor in roasting process.The rotary kiln of prior art is because of structural relation, and the limited time that the material of need roasting stops therein causes the activity coefficient of material in kiln all very low thus, and between 0.014-0.08, its production efficiency is low, energy consumption is big usually.
The utility model content
The technical problems to be solved in the utility model is that the defective at prior art exists proposes a kind of rotary kiln body that is provided with collet, can increase material filling coefficient in the kiln, prolong residence time of material, thereby increase output, energy savings, reduce production costs.
Technical solution of the present utility model is, the described rotary kiln body that is provided with collet has the kiln body that is provided with refractory insulating layer, and its design feature is, is provided with together or above collet together at described kiln body inwall.
Below make and further specifying.
Referring to Fig. 1, the utility model has the kiln body 1 that is provided with refractory insulating layer 2, and its design feature is, is provided with together or (for example one to 20 road, or more) collet 4 together at described kiln body 1 inwall.
Described collet 4 is fixedly installed on the inwall of described kiln body 1; And the height of collet 4 (being the height of its circle body) in kiln body 1 internal projection can be this position, collet 4 place kiln body internal diameter 0.01-0.35 doubly; Distance (being the spacing of collet) between described adjacent two collets 4 can be the kiln body internal diameter 0.3-10 of this place times.
Described collet 4 can adopt refractory concrete to burn casting or build by laying bricks or stones with prefabricated refractory brick and form, and also can adopt the heat resistant and wear resistant metal material to make, and goes back available metal material combined fire resistant concrete and makes, and adopt other appropriate materials to make.
Design of the present utility model and operation principle are, described rotary kiln body 1 rotates when operation vertically, and the discharging opening of kiln body has certain height poor (for example the kiln body of long 14600mm head and the tail difference in height is generally 600mm) than charging aperture, material flows downwards in kiln body rotary course in the kiln, set collet 4 plays the effect that prolongs material material filling coefficient in kiln residence time and increase kiln, output raising, energy consumption are reduced, saved production cost.
As known from the above, the utility model is a kind of rotary kiln body that is provided with collet, be suitable for the various powder of roasting (grain) shape tcrude ore or fine ore, be specially adapted to the roasting preliminary treatment processing of gold ore, the interior material filling coefficient of kiln is increased exponentially, reach 0.1-0.25, and prolong material, thereby be implemented in the purpose that increases exponentially roasting output and energy savings, reduction roasting apparatus specific investment cost cost under identical kiln body bulk and the roasting working condition at kiln residence time.
Description of drawings
Fig. 1 is the vertical sectional structure chart of a kind of embodiment of the present utility model.
In the drawings:
1-kiln body, 2-refractory insulating layer,
3-material, 4-collet.
The specific embodiment
The utility model kiln body according to Fig. 1 and said structure, shell is made of steel plate, the liner refractory insulating layer, after practical structures and shape are scaled as shown in Figure 1, entire length 14600mm, kiln body head and the tail difference in height is 600mm during actual installation, and nine road collets are set in kiln, and its average headway is that 1500mm, height are determined to get final product in ratio shown in Figure 1.
Claims (3)
1, a kind of rotary kiln body that is provided with collet has the kiln body 1 that is provided with refractory insulating layer 2, it is characterized in that, is provided with together or the collet 4 together at described kiln body 1 inwall.
2, the rotary kiln body that is provided with collet according to claim 1 is characterized in that, the height of described collet 4 be this position, collet 4 place kiln body internal diameter 0.01-0.35 doubly.
3, the rotary kiln body that is provided with collet according to claim 1 is characterized in that, the spacing of described collet 4 is 0.3-10 times of this place's kiln body internal diameter.
