Abstract

The present invention discloses a method solving wide kiln cross-section temperature difference, the wide kiln includes the ejection gun burning mouth channel passing through kiln bulk and the ceramic roller installed in kiln bulk calcined zone and used for laying products; the steps of the method solving wide kiln cross-section temperature difference as follows: a. said kiln bulk calcined zone is equipped with the fuse channel additionally which is penetrated with the ejection gun burning mouth channel; b. two sides temperature of the wide kiln is reduces; c. combustion air amount is reduced; the circumference of said fuse channel about is 1/4 of inner diameter of kiln bulk calcined zone; the circumference of said fuse channel about is 1/3of inner diameter of kiln bulk calcined zone. The invention increases the length of the calcined channel, can guide flame into the middle zone of kiln bulk calcined zone, so reduces the cross-section temperature difference of kiln bulk; it decreases the calcined time of products, the size differences in left, central and right direction of calcined products are controlled in 2-3 mm, the color-difference is reduced, the products passing percent is significantly increased, product quality is stable, the product cost is reduced and it has vast market economic benefits.

Description

A kind of method that solves section temperature difference of broad kiln

Technical field

The present invention relates to a kind of solution and fire the method that there is defective in kiln that building and ornament materials use, particularly a kind of method that solves section temperature difference of broad kiln.

Background technology

The creed that " Science and technology constitutes a primary productive force " this people from world today given altogether is the power source that countless countries promote national economy.At 1 year of Chinese Eleventh Five-Year Plan plan, " autonomous innovation " was the central point that each enterprise enhances the competitiveness, gives play to a subjective initiative.In the prior art, ceramic tile is with its density height, contraction distortion is little, wearability is good, decorative effect preferably, and become the object of customer selecting, has vast market, but because in the sintering procedure of ceramic tile, all there is section temperature difference in process of production in wide roller kiln, improving output especially, a product left side can appear when shortening firing period, in, right size differs bigger than normal, it is many that aberration appears in product, the serious product percent of pass that causes descends, ceramic enterprise caused than large economy lose, the front end of the spray gun burner channel of the expanded letter kiln clinkering zone high-temperature region of prior art ends in the inwall of kiln body, when jet flames, need bigger combustion air amount, penetrate apart from being subjected to certain limitation, the flame projected area is little, and disperse, penetrate only in about 1/3 place of porcelain roller bar that is used to be placed on goods, fire district's non-uniform temperature thereby make, kiln body two sides temperature is higher, produces section temperature difference, makes the product each several part be subjected to temperature inhomogeneous, cause yield rate low, the product aberration is big, product percent of pass is low, and firing period is long, and product cost is higher.

Summary of the invention

The objective of the invention is to overcome the defective of prior art, a kind of method that improves the solution section temperature difference of broad kiln of yield rate is provided.This method can make that the product aberration reduces, product percent of pass improves, and firing period shortens, cost reduces.

The objective of the invention is to be achieved through the following technical solutions:

A kind of method that solves section temperature difference of broad kiln, this expanded letter kiln comprises the spray gun burner channel that runs through the kiln body, is located at kiln body firing zone, is placed on the porcelain roller bar of goods; This solves the method for section temperature difference of broad kiln, and step is as follows:

A. described kiln body firing zone is set up the fiery passage of leading with the perforation of spray gun burner channel, and the spray gun burner channel is extended to the kiln intracoelomic cavity, increases the length of firing passage, thereby flame is introduced kiln body firing zone middle part; , the temperature increase time of kiln body firing zone is shortened greatly;

B, reduce combustion air amount.

The present invention can reach following beneficial effect after adopting technique scheme:

1, rational in infrastructure, simple.The present invention extends to the kiln intracoelomic cavity with the spray gun burner channel, has increased the length of firing passage, flame can be introduced kiln body firing zone middle part, reduces the kiln two sides temperature simultaneously, and can correspondingly reduce combustion air amount, thereby reduce the kiln body section temperature difference.Energy-saving and environmental protection.The present invention can shorten the product firing period, thereby increase work efficiency after flame is introduced kiln body firing zone middle part, reaches the purpose of energy-saving and environmental protection.

2, constant product quality, performance are good.After the present invention was come into operation, product was fired satisfactory for result, and product burns till the difference in size left, center, right and is controlled at 2～3 millimeters, and aberration obtains reducing, and product percent of pass rises significantly, and product quality is more stable.

3, long service life.The present invention has done the improvement of science on the basis of existing technology, reduced that product fires in case of necessity between, make the kiln body obtain suitable rest and reorganization, avoided mechanical fatigue, prolonged the service life of kiln body; Simultaneously, the raising of product quality has also prolonged service life of product.

5, reduced cost.After the present invention has overcome the defective of prior art, the quality of product is improved, has but reduced the firing time, reduced percent defective,, strengthened the competitive advantage of product, have the vast market economic benefit so reduced cost significantly.

The specific embodiment

Below in conjunction with drawings and the specific embodiments the present invention is described in further detail:

As shown in Figure 1

Fig. 1 is a kiln body firing zone schematic cross-section in the prior art.In Fig. 1, place on the porcelain roller bar 3 at goods 2, spray gun burner channel 4 is passed the kiln body to kiln body 1 inwall, and when when goods 2 enter the precalculated position, flame 5 arrives firing zone 6 internal diameters 1/4 place only by spray gun burner channel 4, this structure needs bigger combustion air amount, and making kiln body 1 two sides temperature higher, there is section temperature difference in kiln body 1, so must improve the bulk temperature of kiln body 1 firing zone 6 long time, just can reach at the required firing temperature of goods 2, it is long that it fires the cycle; Power consumption is big; Product the left, center, right size occurs and differs bigger than normal; Aberration appears in product easily; Cause unstable product quality.

As shown in Figure 2

Fig. 2 is kiln body firing zone schematic cross-section among the present invention.In Fig. 2, add one at the front end of spray gun burner channel 4 and lead fiery passage 7 by what exotic material was made, can be with described 1/4 place that fiery passage 7 extends to kiln body 1 firing zone 6 internal diameters or 1/3 place (volume of apparent goods and decide) of leading, thereby make lance ejection, the flame 5 that enters kiln body 1 through spray gun burner channel 4 extends to the position of porcelain roller bar 3 near the middle part along leading fiery passage 7, like this, when placing porcelain roller bar 3 to fire at goods 2, flame 5 sprays in the area of porcelain roller bar 3 and increases greatly through leading fiery passage 7 by spray gun burner channel 4, and it is more concentrated, simultaneously can reduce the kiln two sides temperature, thereby shortened the temperature increase time of kiln body 1 firing zone 6 greatly, and can correspondingly reduce combustion air amount, saved firing time and energy consumption.
