Abstract
A kind of Novel tunnel furnace preheating zone, comprises preheating zone body, also comprises the roof beam that is arranged on kiln top and the lateral column near kiln side wall place, lateral column and vertical direction angle non-vanishing.The invention has the beneficial effects as follows: this New Pre torrid zone changes the structure of preheating zone in prior art, thus greatly change the large situation of preheating zone upper and lower temperature difference, the use of roof beam and lateral column serves good choked flow and guide functions, top hot-air is flowed downward in order, thus dramatically reduce the temperature difference, have that structure is simple, easy-to-use, with low cost, the advantage of long service life.
Description
Technical field
The present invention relates to tunnel kiln technical field, especially relate to a kind of change by structure, the Novel tunnel furnace preheating zone of the preheating zone temperature difference can be effectively reduced.
Background technology
The horizontal flame formula kiln of tunnel cave to be a kind of air-flow be bottom horizontal flow sheet, for the product such as firing ceramics, refractory material.In conventional art, tunnel furnace preheating zone floats due to thermal current, cold airflow sinks, there is the very large temperature difference (this temperature difference is maximum reaches 300 DEG C-400 DEG C), the existence of this larger temperature difference easily causes goods to ftracture, and the product firing time is extended, it is uneven to burn till quality, reduces furnace output and quality, therefore, how reducing the preheating zone temperature difference is industry issues that need special attention.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 large reason of the tunnel cave temperature difference and reduce the measure of this temperature difference, the concrete measure used can be shut import and export that tunnel is connected with air, close exterior wall, on time gaza with metal material, closed smoke exhausting props up sluice gate etc. outside hole, the use of above-mentioned measure can be summed up as the sealing improving preheating zone.Be published in " ceramic engineering " the 32nd volume the 6th phase " brief talking the measure reducing preheating zone, tunnel upper and lower temperature difference " literary composition in, improvement from the adjustment, kiln structure of kiln structure size and the improvement of code blank structure three aspects, in the improvement of its kiln structure, propose and use lightweight refracrory to do the behaves such as lining brick, the sealing of reinforcement kiln car 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 sections of articles, be proposed concrete improvement project, but all do not propose corresponding improvement in the structure improvement of preheating zone.Application number is 2007201534459, application title is in the patent application of " modified node method of ceramic roller kiln preheating zone ", disclose a kind of modified node method of tunnel cave, use this structure that the upper and lower temperature difference of preheating zone can be made to reduce, technical scheme is within the scope of the first humidity province 80-350 DEG C in preheating zone, arrange one group every the kiln top of 2 meters and stir air curtain, spray in kiln by the waste heat wind and the reverse high speed of flue gas that come from salband, simultaneously in the kiln of this section, upper and lower interlaced arrangement 4 overlaps spray hot wind pipes; Within the scope of tunnel furnace preheating zone second humidity province 350-650 DEG C, the 3 cover high temperature speed governing nozzles every the Yao Qiang bottom interlaced arrangement of 2 meters, the corresponding spray hot wind pipe arranging respective amount in positive the other side's kiln top on same cross section.This kind of structure to make in kiln up and down, internal and external temperature is very even, reduces the temperature difference, and accelerates go-cart speed, thus improve product burn till Quality and yield.But this kind of modified node method does not still relate to the improvement to preheating zone structure.
Summary of the invention
The object of the invention is to overcome the shortcoming existed in prior art, the Novel tunnel furnace preheating zone that a kind of structure is simple, saving material, result of use are good is provided, this preheating zone by increasing back timber and lateral column on preheating zone, reach the object reducing the temperature difference, the technical scheme used is: a kind of Novel tunnel furnace preheating zone, comprise preheating zone body, it is characterized in that: described preheating zone also comprises the roof beam that is arranged on kiln top and the lateral column near kiln side wall place, described lateral column and vertical direction angle non-vanishing.
Technical scheme of the present invention also has: be two at the lateral column of same lateral position, symmetrical distribution.
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 changes the structure of preheating zone in prior art, thus greatly change the large situation of preheating zone upper and lower temperature difference, the use of roof beam and lateral column serves good choked flow and guide functions, top hot-air is flowed downward in order, thus dramatically reduce the temperature difference, have that structure is simple, easy-to-use, with low cost, the advantage of long service life.
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 kiln top, and 2 is roof beam, and 3 is kiln walls, and 4 is lateral columns.
Detailed description of the invention
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 preheating zone body, be arranged on the roof beam 2 on kiln top and the lateral column 4 near kiln side wall place, and lateral column 4 is non-vanishing with vertical direction angle.Be two at the lateral column 4 of same lateral position, symmetrical distribution.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, under the guide functions of the simultaneously lateral column 4 of thermal current on kiln wall 3, also flow downward, thus top thermal current is down moved generally.At the volley, the thermal current on top and the cold airflow of bottom stir, and reach the effect of homogenizing gas temperature, thus effectively reduce upper and lower temperature difference.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited only to above-mentioned citing, and the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement, also belong to protection scope of the present invention.
Claims (3)
1. a Novel tunnel furnace preheating zone, comprises preheating zone body, it is characterized in that: described preheating zone also comprises the roof beam that is arranged on kiln top and the lateral column near kiln side wall place, described lateral column and vertical direction angle non-vanishing.
