Abstract
A novel preheating belt for a tunnel kiln comprises a preheating belt body, a top beam arranged at the top of the kiln and a lateral column arranged close to the lateral wall of the kiln, wherein an included angle formed by the lateral column and the vertical direction is not zero. The novel preheating belt for the tunnel kiln has the advantages that the structure of the preheating belt in the prior art is changed, and accordingly, large temperature difference between the upper portion of the preheating belt and the lower portion of the preheating belt is greatly changed; the top beam and the lateral column can block and guide flow, so that hot air at the upper portion flows downwards orderly, and the temperature difference is greatly reduced; the novel preheating belt for the tunnel kiln is simple in structure, convenient to use, low in cost and long in service life.
Description
Technical field
The present invention relates to the tunnel kiln technical field, especially relate to a kind of change by structure, can effectively reduce the Novel tunnel furnace preheating zone of the preheating zone temperature difference.
Background technology
Tunnel cave is the horizontal flame formula kiln that a kind of air-flow is bottom horizontal flow sheet, for products such as firing ceramics, refractory materials.In conventional art, tunnel furnace preheating zone is because thermal current floats, cold airflow sinks, there is the very large temperature difference (this temperature difference maximum can reach 300 ℃-400 ℃), the existence of this larger temperature difference easily causes the goods cracking, and the product firing time is extended, and burn till quality inhomogeneous, reduced furnace output and quality, therefore, how reducing the preheating zone temperature difference is the problem that the industry is paid close attention to.Be published in " Jingdezhen Ceramic " 1985 the 4th interim " brief talking the tunnel furnace preheating zone temperature difference " (author: thank to Chang'an) literary composition, itemize the reason that the tunnel cave temperature difference is large and reduced the measure of this temperature difference, the concrete measure used can be shut import and export that tunnel and atmosphere be connected, with metal material seal exterior wall, gaza, closed smoke exhausting prop up sluice gate etc. outside hole on time, the use of above-mentioned measure can be summed up as the sealing of improving preheating zone.Be published in " brief talking the measure that reduces preheating zone, tunnel upper and lower temperature difference " literary composition of " ceramic engineering " the 32nd the 6th phase of volume, from the adjustment of kiln structure size, on kiln structure improvement and the code blank structure three aspects of improvement, in the improvement of its kiln structure, having proposed the use lightweight refracrory does lining brick, strengthens the behaves such as kiln car sealing and the structural improvement of kiln vehicle surface, the problem of preheating zone upper and lower temperature difference all paid close attention in above-mentioned two pieces of articles, concrete improvement project has all been proposed, but on the architecture advances of preheating zone, all there is no to propose corresponding the improvement.Application number is 2007201534459, applies for that title is in the patent application of " the improvement structure of ceramic roller kiln preheating zone ", a kind of improvement structure of tunnel cave is disclosed, use this structure that the upper and lower temperature difference of preheating zone is reduced, technical scheme is in the first humidity province 80-350 ℃ scope of preheating zone, every the kiln top of 2 meters, arranged that is stirred an air curtain, waste heat wind and the reverse high speed of flue gas that will come from salband spray in kiln, simultaneously in the kiln of this section upper and lower interlaced arrangement 4 cover spray hot wind pipes; In tunnel furnace preheating zone the second humidity province 350-650 ℃ scope, every the Yao Qiang bottom interlaced arrangement of 2 meters 3 cover high temperature speed governing nozzles, the corresponding spray hot wind pipe of having arranged respective amount over against square kiln top on same cross section.That this kind structure can make is upper and lower in kiln, internal and external temperature is very even, has reduced the temperature difference, and has accelerated go-cart speed, thereby improved the Quality and yield that burns till of product.But this kind improves structure does not still relate to the improvement to the preheating zone structure.
Summary of the invention
The object of the invention is to overcome the shortcoming existed in prior art, provide a kind of simple in structure, save material, the good Novel tunnel furnace preheating zone of result of use, this preheating zone is by increasing back timber and lateral column on preheating zone, reach the purpose that reduces the temperature difference, the technical scheme of using is: a kind of Novel tunnel furnace preheating zone, comprise the preheating zone body, it is characterized in that: described preheating zone also comprises the roof beam that is arranged on kiln top and near the lateral column at kiln side wall place, described lateral column and vertical direction angle are non-vanishing.
Technical scheme of the present invention also has: the lateral column in same lateral position is two, and left-right symmetry distributes.
Technical scheme of the present invention also has: between the lateral column of different lateral position, longitudinal separation is 1 meter.
The invention has the beneficial effects as follows: this New Pre torrid zone has changed the structure of preheating zone in the prior art, thereby greatly changed the large situation of preheating zone upper and lower temperature difference, good choked flow and guide functions have been played in the use of roof beam and lateral column, make the top hot-air flow downward in order, thereby greatly reduced the temperature difference, had advantage simple in structure, easy-to-use, with low cost, long service life.
The accompanying drawing explanation
Accompanying drawing 1 is transversary schematic diagram of the present invention, and accompanying drawing 2 is vertical structure schematic diagrames of the present invention, and wherein 1 is the kiln top, the 2nd, and roof beam, the 3rd, kiln wall, the 4th, lateral column.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.The invention discloses a kind of Novel tunnel furnace preheating zone, comprise the preheating zone body, be arranged on the roof beam 2 on kiln top and the lateral column 4 at close kiln side wall place, lateral column 4 is non-vanishing with the vertical direction angle.Lateral column 4 in same lateral position is two, and left-right symmetry distributes.Between the lateral column 4 of different lateral position, longitudinal separation is 1 meter.
During use, the thermal current of preheating zone flows from right to left, and thermal current is subject to the choked flow of roof beam 2 and the effect of water conservancy diversion, flow downward, thermal current, under the guide functions of the lateral column 4 on kiln wall 3, also flows downward, thereby makes the top thermal current down move generally simultaneously.At the volley, the thermal current on top and the cold airflow of bottom stir, and have reached the effect of homogenizing gas temperature, thereby have effectively reduced upper and lower temperature difference.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention also is not limited only to above-mentioned giving an example, and those skilled in the art make in essential scope of the present invention variation, remodeling, interpolation or replacement, also belong to protection scope of the present invention.
Claims (3)
1. a Novel tunnel furnace preheating zone, comprise the preheating zone body, it is characterized in that: described preheating zone also comprises the roof beam that is arranged on kiln top and near the lateral column at kiln side wall place, described lateral column and vertical direction angle are non-vanishing.
2. according to Novel tunnel furnace claimed in claim 1 preheating zone, it is characterized in that: the lateral column in same lateral position is two, and left-right symmetry distributes.
