Abstract
The utility model relates to a sharp quenching device for a large electrotechnical porcelain tunnel kiln, which comprises a rapid-cooling zone and a moderate-speed cooling zone behind the rapid-cooling zone. The rapid-cooling zone comprises two rows of wind-screen outlets per side and two rows of strong-wind screen openings per side of both sides of the kiln wall, and wind is supplied to the wind-screen outlets and the strong-wind screen openings through strong-wind pipes by a distribution chamber. The strong-wind screen openings per side lie in the row one and row three while the wind-screen outlets per side lie in the row two and the row four; and the positions of the strong-wind screen openings and those of the adjacent wind-screen outlets are mutually staggered. The moderate-speed cooling zone comprises an upper row of 12 pre-heating uniform cooling wind openings and a lower row of 12 pre-heating uniform cooling wind openings per side of both sides of the kiln wall, and wind is supplied to the pre-heating uniform cooling wind openings and the pre-heating uniform cooling wind openings through a cooling wind pipe by a pre-heating mixing chamber. The sharp quenching device has the advantages that the product qualification rate is improved to 92% from 76%, and not only lowers energy consumption and improves enterprise benefit, but also improves the working atmosphere for staff and reduces green house gas emission.
Description
Technical field
The utility model relates to a kind of quenching apparatus of large-scale electroceramics tunnel cave.
Background technology
Along with the progress of society, Electric Ceramics Kiln has changed the shuttle kiln that burns gas, oil firing into from traditional coal-fired kiln, and what have more develops into energy-saving tunnel type kiln.But the cooling system of general large-scale electroceramics tunnel cave has but become big problem, because porcelain moulded pottery not yet put in a kiln to bake body is thick and heavy, if cooling down high-temperature base substrate rapidly, will be because of the inconsistent consequence that causes the fried porcelain of base substrate of cooling inside and outside the porcelain base; If cooling velocity is not enough, then the outward appearance of product and physical strength can't meet the demands again.
Summary of the invention
The purpose of this utility model is to design a kind of quenching apparatus of large-scale electroceramics tunnel cave, it can provide the powerful air curtain wind that can be the cutoff of high temperature base substrate, can provide the preheating that can relax the base substrate internal-external temperature difference even cooling air again, make kiln can burn desirable product quality, improve economic benefit of enterprises, improve production environment.
The quenching apparatus of the so-called a kind of large-scale electroceramics tunnel cave of the utility model, it comprises kiln body of wall 1, it is characterized in that: described quenching apparatus is made up of for two sections rapid cooling zone and the middling speed cooling zone that is positioned at after the rapid cooling zone, rapid cooling zone wherein comprises every side 2 row air curtain exhaust outlets 2 and the every side 2 big powers' strong wind curtain mouths 3 of being located at kiln body of wall 1 both sides and being blown through distributor chamber 6 by powerful airduct 7, every side 2 big powers' strong wind curtain mouths 3 occupy the position of 1 and 3 row, every side 2 row air curtain exhaust outlets 2 then occupy the position of 2 and 4 row, and each powerful air curtain mouth 3 staggers mutually with the position of adjacent air curtain exhaust outlet 2; Middling speed cooling zone wherein then comprises to be located at kiln body of wall 1 both sides and to arrange each 12 even cooling air port 4 of preheating by cooling duct 8 through every side upper and lower two of preheating mixing chamber 5 air-supplies.
In addition, cavity length in the kiln that described rapid cooling zone occupies, only 1/2nd of the interior cavity length of the kiln that occupies for described middling speed cooling zone.
The beneficial effects of the utility model are: for the large tunnel kiln of a long 100m, wide 1.78m, high 1.26m, if every day is with 10000m
36000 of gas production 7T type electroceramics, then product percent of pass can bring up to 92% from original 76%, and 960 of the qualified products of promptly increasing day by day are saved 6% 600m simultaneously again
3Natural gas has not only improved the benefit of enterprise, has also reduced the discharging of greenhouse gases in addition, has improved employee's working environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Among the figure: 1-kiln body of wall, 2-air curtain exhaust outlet, the powerful air curtain mouth of 3-, the even cooling air port of 4-preheating, 5-preheating mixing chamber, 6-distributor chamber, the powerful airduct of 7-, 8-cooling duct.
The specific embodiment
As figure, a kind of quenching apparatus of large-scale electroceramics tunnel cave, it comprises kiln body of wall 1, it is characterized in that: described quenching apparatus is made up of for two sections rapid cooling zone and the middling speed cooling zone that is positioned at after the rapid cooling zone, rapid cooling zone wherein comprises every side 2 row air curtain exhaust outlets 2 and the every side 2 big powers' strong wind curtain mouths 3 of being located at kiln body of wall 1 both sides and being blown through distributor chamber 6 by powerful airduct 7, every side 2 big powers' strong wind curtain mouths 3 occupy the position of 1 and 3 row, every side 2 row air curtain exhaust outlets 2 then occupy the position of 2 and 4 row, and each powerful air curtain mouth 3 staggers mutually with the position of adjacent air curtain exhaust outlet 2; Middling speed cooling zone wherein then comprises to be located at kiln body of wall 1 both sides and to arrange each 12 even cooling air port 4 of preheating by cooling duct 8 through every side upper and lower two of preheating mixing chamber 5 air-supplies.In addition, cavity length in the kiln that described rapid cooling zone occupies, only 1/2nd of the interior cavity length of the kiln that occupies for described middling speed cooling zone.
What also must illustrate is, the indication of large size arrow is the kiln car moving direction among Fig. 1, the indication of medium size arrow be the flow direction of powerful air curtain wind, small size arrow indication then be the flow direction of the even cooling air of preheating.
The beneficial effect of this quenching apparatus mainly contains the following aspects:
The thermal-flame atmosphere that 1, can prevent the kiln high temperature section is invaded the later stage cooling section, avoids waste of fuel And thermal loss, powerful wind-force seals thermal-flame atmosphere.
2, set 2 heavy powerful air curtain mouths, powerful wind-force can cool off fast the porcelain billet surface and make it crystallization, With physics and the appearance requirement that satisfies electrotechnical porcelain product.
3, use the even cooling air middling speed of preheating cooling electric porcelain products, can prevent that porcelain base substrate internal and external temperature from descending Inconsistent, improve 16 percentage points of electrotechnical porcelain product qualification rates.
4, can reduce the temperature of kiln discharge product, improve working environment, reduce greenhouse gas emission.
