The shuttle-type high-temperature sintering kiln is characterized in that a kiln lining is a thin wall light type, a kiln wall is an anchor structure, and a sealing uses a contact wedge structure. The utility model also uses a high-speed temperature-adjustable burner provided with a telescopic type spray gun, and the sintering temperature reaches to 1500-1800DEG. C. The utility model is widely used for the high-temperature sintering of a plurality of products of the industries of ceramic, electric porcelain, grinding wheel, refractory material, etc. The shuttle-type high-temperature sintering kiln has small kiln lining stored heat, favorable thermal insulation effect, few tolerant material consumption, high heating temperature, short heating cycle, good sealing effect and high thermal efficiency.
Description
The utility model relates to a kind of shuttle-type high temperature burning kiln, be characterized in that kiln lining is that thin-walled is light-duty, kiln wall and hermetically-sealed construction are reasonable, employing has the high speed temperature adjustment burning of extension type spray gun chews, and the high temperature that is widely used in industry various products such as pottery, electroceramics, emery wheel, refractory material burns till (1500-1800 ℃).
At present domestic kiln temperature commonly used all adopts heavy refractory material kiln lining greater than 1500 ℃ shuttle kiln, and more than 480mm, not only the refractory consumption rate amount is big at least for wall thickness, and amount of stored heat is also big, and heating cycle is long, and the thermal efficiency is low, the cost height.Kiln is taked bent envelope form sealing, and sealing effectiveness is bad, has limited effective absorption of heat in the kiln like this, has increased hear rate, and the thermal efficiency is low.
In view of the problems referred to above that exist, the purpose of this utility model is that a kind of kiln lining amount of stored heat of design is little, good heat-insulation effect, anti-material consumption is few, firing temperature is high, heating cycle is short, good sealing effect, light thin wall high temperature shuttle kiln that the thermal efficiency is high.
For realizing this purpose, this light thin wall high temperature shuttle kiln of the utility model design, by outer steel shell (1), side wall (2), wicket (3), headwall (4), kiln top (5), kiln car (6), burn and chew brick (7), burn and chew (8) and form, burning is chewed brick (7) interlaced arrangement on both walls (2), burns to chew brick (7) and also promptly burn the quantity of chewing (8) and kiln car (6) and decide by the specification of the different and kiln of burnt product is big or small; It is characterized in that:
1). kiln lining is a thin wall type, and total wall thickness is 300-460mm, kiln lining adopt thermal shock resistance greater than 15 times (1000 ℃, air cooling), (detected temperatures * 8hr), bulk density are 1.0-1.6g/cm less than 1% heavily to burn shrinkage factor
3The light thermal-shield refractory goods;
2). side wall (2) and kiln car (6), kiln car (6) and kiln car (6), kiln car (6) and wicket (3), wicket (3) and side wall (2), wicket (3) He Yaoding (5) are the sealing of contact wedge structure;
3). the kiln wall is an anchor structure, be made up of anchored brick (9), anchoring piece (10), retainer ring (11), kiln liner (12), kiln time lining (13) and fireclay insulating refractory (14), kiln liner (12) and kiln time lining (13) is connected and fixed by anchored brick (9), anchoring piece (10) and retainer ring (11) and outer steel shell (1);
4). burning is chewed (8) and is adopted the high speed temperature adjustment burning that has the extension type spray gun to chew.
Owing to take above-mentioned measure, make that the utility model light thin wall high temperature shuttle kiln heat accumulation of kiln amount is little, good heat-insulation effect, anti-material consumption is few, heating-up temperature is high, heating cycle is short, good sealing effect, thermal efficiency height, adjustment are flexible.
Introduce the detailed structure content of the utility model light thin wall high temperature shuttle kiln below in conjunction with drawings and Examples.
Fig. 1 analyses and observe overall structure figure for light thin wall high temperature shuttle kiln.
Fig. 2 is the A-A cutaway view of light thin wall high temperature shuttle kiln shown in Figure 1.
Fig. 3 is the partial enlarged drawing at light thin wall high temperature shuttle kiln B position shown in Figure 1.
Fig. 4 is the partial enlarged drawing at light thin wall high temperature shuttle kiln C position shown in Figure 1.
Embodiment as shown in Figure 1, a 8m
3Light thin wall high temperature shuttle kiln, its length is 3.719 * 1.634 * 1.41m, burns till goods such as magnesia slide plate, firing temperature is 1700 ℃.The kiln lining material adopt inferior (1000 ℃, air cooling) surplus the heat-resisting shake stability 20, heavily burn shrinkage factor less than 0.5% (1600 ℃ * 8hr), bulk density is 1.4g/cm
3The light high-alumina insulating refractory product.The total wall thickness of kiln lining is 350mm, can significantly reduce the kiln lining amount of stored heat like this, also can save the consumption of anti-material simultaneously, shortens heating cycle, has therefore reduced hear rate, has improved the thermal efficiency.This kiln is established 6 burnings altogether and is chewed brick (7), and its interlaced arrangement is on both walls (2), and this helps even heating.Each burning is chewed and all is provided with a high speed temperature adjustment that has an extension type spray gun in the brick (7) and burns and chew (8), and this burning is chewed and helped the low temperature igniting, and high temperature heating and adjustment are flexible, and fuel can adopt gas or liquid fuel.
As shown in Figure 3, the kiln wall is an anchor structure, be made up of anchored brick (9), anchoring piece (10), retainer ring (11), kiln liner (12), kiln time lining (13) and fireclay insulating refractory (14), kiln liner (12) and kiln time lining (13) is connected and fixed by anchored brick (9), anchoring piece (10) and retainer ring (11) and outer steel shell (1).Retainer ring (11) is welded on the outer steel shell (1), anchored brick (9) is built in the kiln liner (12) of kiln wall, anchoring piece (10) is built in masonry by pine, in the annular distance of an insertion retainer ring (11), the other end is inserted in the hole of anchored brick (9), the kiln wall is in temperature-rise period like this, can about, move left and right, and can in kiln, not tilt.
