Abstract
The utility model provides a roller kiln which comprises a kiln body and a roller group which is composed of a plurality of rollers, wherein the shaft line of each roller is vertical to the length direction of the kiln body, the kiln body is provided with a preheating zone, a calcining zone and a cooling zone, inner passages of the kiln are all arranged in the preheating zone, the calcining zone and the cooling zone, the inner passage of the kiln of the preheating zone and the roller group are arranged in an oblique way that the inlet end of the inner passage of the kiln of the preheating zone is high and the outlet end of the inner passage of the kiln is low, and the ratio of the height difference of the inlet end of the oblique inner passage of the kiln and the outlet end to the horizontal length of the preheating zone is from 1/5 to 1/200. The utility model uses the oblique way to arrange the roller group and the inner passage of the kiln, causes the kiln to have a definite natural chimney pumping force, can properly reduce space in the kiln and obtains the function of energy saving. The utility model has the advantages of simple construction and high safety.
Description
Technical field
The utility model relates to a kind of furnace construction, relates in particular to a kind of kiln structure with roller-way.
Background technology
Roller kilns have the history of decades, are used for burning till of ceramic.Roller kilns roughly are divided into preheating zone, clinkering zone and salband, many rollers rod position roll rod group wherein, every roller rod level and perpendicular to the length direction of kiln, the kiln body is stretched out at the two ends of roller rod.Referring to Fig. 1 and Fig. 2, it shows roller kilns body 1 of the prior art, and wherein green compact 8 place on the roller rod 3, and roller rod 3 rotates it by transmission device, and ceramic 8 moves to the other end (kiln tail) by an end (kiln hood) of kiln body 1.The clinkering zone at the middle part of kiln body about in the of 10 both sides by burner 7 heat supply in kiln body 1, smoking blower fan 5 is taken out the hot gas of kiln middle part clinkering zone 10 to kiln hood through kiln space and is discharged, hot gas and green compact 8 produce heat exchange, kiln body 1 has insulation effect, make green compact 8 reach the purpose of burning till to ceramic 2, ceramic 2 shifts out kiln body 1 through behind the salband 11.
Usually the interior outage degree on roller rod 3 tops has 30-60cm, flows in the long kiln of rice up to a hundred to guarantee hot gas.But this height as be provided with that low then gas-flow resistance is big, being provided with too highly then needs the more energy to keep temperature than large space, to reach the purpose of burning till, certainly will waste energy like this.
Summary of the invention
The purpose of this utility model provides a kind of roller kilns, and this kiln body can reduce the draft of blower fan and reduce the kiln space height, saves the energy.
The roller kilns that the utility model provides, has the club group that kiln body and a plurality of roller rod is formed, the axis of roller rod and kiln body length direction are perpendicular, the kiln body has preheating zone, clinkering zone and salband, be equipped with the kiln internal channel in preheating zone, clinkering zone and the salband, wherein kiln internal channel in the preheating zone and roller rod group is obliquely installed with preheating zone kiln internal channel arrival end height, mode that the kiln internal channel port of export is low, and the ratio of the horizontal length of the arrival end of the kiln internal channel of inclination and the difference in height of the port of export and preheating zone is 1/5～1/200.
The utility model is by being provided with roller rod group and kiln internal channel in the mode that tilts, make kiln have certain natural stack draught, under the situation that air motion speed in kiln equates, the required external force (mechanical draft) of blower fan reduces, can also suitably reduce the space in the kiln, reach energy-conservation effect.And the utility model construction is simple, safe and reliable, has good economic benefit and social benefit.

The specific embodiment
Below, with reference to accompanying drawing, describe a preferred embodiment of the present utility model in detail.
As shown in Figure 3, it shows a kind of tilting roller kilns, uses identical Reference numeral with the parts of same section shown in Figure 1.These tilting roller kilns have preheating zone 9, clinkering zone 10 and salband 11.Be equipped with the kiln internal channel in preheating zone 9, clinkering zone 10 and the salband 11, green compact 8 place on the roller rod 3, and roller rod 3 is driven and rotated by transmission device, and green compact 8 are by an end (kiln hood of kiln body 1, be the preheating zone arrival end) move to the other end (kiln tail, the i.e. port of export of salband) of kiln body 1.In the clinkering zone 10 at kiln body 1 middle part, both sides are by burner 7 heat supply in kiln body 1 up and down, and smoking blower fan 5 is taken out kiln 1 middle heat flue gas to kiln hood through kiln space and discharged, hot flue gas and green compact 8 produce heat exchange, green compact 8 Low fire ceramic goods 2 after supercooling, shift out kiln body 1.
In these tilting roller kilns, roller before the clinkering zone 10 rod 3 formed roller rod groups are obliquely installed, be roller rod group to be obliquely installed in preheating zone kiln internal channel arrival end height, mode that the kiln internal channel port of export is low, roller rod group is 1/50 at the ratio of the horizontal length that the difference in height and the roller rod at arrival end place and port of export place are organized.Simultaneously, the kiln internal channel in the preheating zone is obliquely installed with arrival end height, mode that the port of export is low, and the ratio of the horizontal length of the arrival end of the kiln internal channel of inclination and the difference in height of the port of export and preheating zone is 1/50.Therefore it is higher to form kiln hood in preheating zone 9, and kiln body middle part is low, and the kiln body passage of inclination is similar to imperial kiln.Each roller rod 3 levels and perpendicular to the length direction of kiln body 1 and protrude in kiln body 1 and place.
In the present embodiment, the angle of inclination of the kiln internal channel in the preheating zone is identical with the angle of inclination of roller rod group, but also can be slightly variant.Simultaneously, the ratio of described difference in height and horizontal length also can be 1/25,1/100 etc., all can realize the purpose of this utility model in 1/5～1/200 scope.
Kiln body passage in the preheating zone is made as tilting, can reduces the draft of smoking blower fan 5.If rod 3 of the roller before the clinkering zone 10 and kiln internal channel are pressed the kiln hood height, the low mode in kiln middle part tilts to place.Be similar to imperial kiln, make it have certain natural stack draught, under the situation that the air motion speed in kiln equates, the required external force (mechanical draft) of blower fan reduces, and can also suitably reduce the space in the kiln, reaches energy-conservation effect.
