Abstract
The invention discloses a main kiln pipe of a rotary kiln. A kiln pipe is lengthened, the temperatures of a first heating group and the last heating group can be increased in consideration of thermal conduction of stainless steel under the condition that the heating groups are not added; by virtue of the heat conduction principle, the front end of the first heating group and the rear end of the last heating group are increasingly and slowly heated, so that temperature increment and temperature reduction speeds can be reduced, simultaneously time at maximum temperature is guaranteed, a broken phenomenon of a rolling material is prevented, and uniform pre-sintering is facilitated; and besides, striking devices are added in a plurality of positions, so that the phenomenon that powder sticks to the wall is greatly changed, the pre-sintering effect is guaranteed, and the difficulty of wall cleaning is reduced.
Description
Technical field
The present invention relates to the rotary kiln technical field, relate in particular to a kind of revolution kiln owner kiln pipe.
Background technology
Rotary kiln refers to rotary calcining kiln (being commonly called as rotary kiln), belongs to the building equipment class.Rotary kiln comprises kiln hood, main kiln pipe and three parts of kiln tail, and wherein, kiln hood is the rotary kiln output section, and diameter is realized sealing greater than the rotary kiln diameter by stainless steel flap and kiln body; Main kiln pipe is the main body of rotary kiln, cylindrical shape, and there are 3～5 rolling rings the centre; The kiln tail is mainly born charging and sealing function at the lid of the similar rotary kiln of feed end shape.
The main kiln pipe (material is stainless steel) of the rotary kiln that prior art is used as shown in Figure 1, kiln pipe 11 outsides are coated with heat-insulation layer 12, its length only has 8.5 meters, and only remains imitation frosted glass and advance the kiln section and designed 1 place's pounder (the first beating device 13).Because the kiln pipe is shorter, cause temperature curve to adjust difficulty, programming rate is too fast, and temperature retention time is short, drops to 700 ℃ excessive velocities, and when causing pre-burning, it is broken easily to roll sheet stock, and the uniformity of Preburning material is difficult to control etc.; Because pounder only has 1 place, causes tube wall powder wall sticking phenomenon serious, not easy to clean, and then the harmful effect larger to the pre-burning mass formation is demanded urgently improving.
Summary of the invention
Problem for prior art exists the object of the invention is to propose a kind of revolution kiln owner kiln pipe, with the uniformity of assurance Preburning material and the effect of pre-burning, and has reduced the difficulty of clear wall.
A kind of revolution kiln owner kiln pipe comprises:
The kiln pipe, length is more than or equal to 11 meters;
Heat-insulation layer is sheathed in the middle of the described kiln pipe outside;
Two groups of beating devices, first group is positioned at described kiln pipe feed end; Second group is positioned at described kiln pipe discharge end.
Preferably, described first group of beating device and described second group of beating device comprise respectively a beating device at least.
Preferably, described first group of beating device comprises the first beating device and the second beating device.
Preferably, described first group of beating device comprises the 3rd beating device.
Among the present invention, owing to lengthened the length of kiln pipe, in the situation that does not increase the heating group, consider stainless thermal conductivity, can improve with last temperature of organizing the heating group first, utilize heat-conduction principle, with the front end (the A position among the figure) of first group of heating group and the gradually slowly heating of rear end (the B position among the figure) of last group, so just can reduce and heat up and cooling rate, guarantee simultaneously temperature retention time, avoid rolling the Fragmentation Phenomena of sheet stock and be beneficial to even pre-burning; In addition, owing to increased the many places pounder, so that the powder wall sticking phenomenon is taken on a new look greatly, guarantee the effect of pre-burning, reduced the difficulty of clear wall.
Description of drawings
Fig. 1 is a kind of revolution kiln owner kiln duct ligation composition in the prior art;
Fig. 2 is a kind of revolution kiln owner kiln duct ligation composition in the embodiment of the invention.
Reference numeral:
11, the kiln pipe; 12, heat-insulation layer; 13, the first beating devices; 21, the kiln pipe; 22, heat-insulation layer; 23, the first beating devices; 24, the second beating devices; 25, the three beating devices.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment:
The embodiment of the invention provides a kind of revolution kiln owner kiln pipe, and as shown in Figure 2, comprising: kiln pipe 21, material are stainless steel, and length is more than or equal to 11 meters; Heat-insulation layer 22 is sheathed in the middle of described kiln pipe 21 outsides; The first beating device 23 and the second beating device 24 are arranged in the front end (the A position of Fig. 2) of first group of heating group; The 3rd beating device 25 is arranged in the rear end (the B position of Fig. 2) of last group, is implemented in and treats that imitation frosted glass advances the kiln section and designs 2 place's beating devices, and kiln discharge section 1 place's beating device amounts to 3 place's pounders.Certainly, treating that the beating device quantity that imitation frosted glass advances the design of kiln section and kiln discharge section can adjust,, for example, treating that imitation frosted glass advances the kiln section and designs 1 place's beating device, kiln discharge section 2 place's beating devices; Or treating that imitation frosted glass advances the kiln section and designs 2 place's beating devices, kiln discharge section 2 place's beating devices etc.
Among the present invention, owing to lengthened the length of kiln pipe, in the situation that does not increase the heating group, consider stainless thermal conductivity, can improve with last temperature of organizing the heating group first, utilize heat-conduction principle, with the front end (the A position among the figure) of first group of heating group and the gradually slowly heating of rear end (the B position among the figure) of last group, so just can reduce and heat up and cooling rate, guarantee simultaneously temperature retention time, avoid rolling the Fragmentation Phenomena of sheet stock and be beneficial to even pre-burning; In addition, owing to increased by 2 place's pounders, so that the powder wall sticking phenomenon is taken on a new look greatly, guarantee the effect of pre-burning, reduced the difficulty of clear wall.
The embodiment of the invention provides the above; only be the better specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
