Description

Sparge ring streaming flaming pushed bat kiln

Technical field

The utility model relates to pushed bat kiln, especially relates to a kind of to pushed bat kiln clinkering zone heat transfer efficiency and the higher sparge ring streaming flaming pushed bat kiln of section temperature uniformity requirement.

Background technology

Pushed bat kiln is a kind of a kind of tunnel cave that adopts fire-resistant push pedal delivery goods to go into the kiln roasting.This kiln mostly is muffle, the advantage that have that the cross section is little, sealing at the bottom of the kiln, no cold air are bled, kiln temperature is even, is easy to burn till fast.But owing to adopt muffle mode baked article, be mainly the solid radiant heat transfer in the kiln, heat-transfer effect is poor than flaming, and the thermal efficiency is low, and burnup is bigger.And when cross dimensions in the kiln (especially kiln inner width) is big, occur the big section temperature difference easily, influence goods and burn till quality.

Summary of the invention

The purpose of this utility model provides a kind of sparge ring streaming flaming pushed bat kiln that can make pushed bat kiln clinkering zone section temperature evenly can improve heat transfer efficiency, reduction burnup again.

The purpose of this utility model is achieved in that the utility model is by the kiln body, the top burner, the bottom burner, push pedal, base plate and backplanes support are formed, the kiln body is by the kiln wall, form at the bottom of Yao Ding and the kiln, the kiln inner wall with the corundum porzite flame-proof brick as liner, feature is that top burner and bottom burner are installed in the both sides of kiln wall, top burner and bottom burner are crisscross arranged up and down, the relevant position on top burner and burner opposite, bottom be respectively equipped with run through the kiln wall on flame-observing hole and following flame-observing hole, build on the backplanes support that forms is installed at the bottom of the kiln by corundum fireproof is brick, material is that the base plate of corundum matter is built by laying bricks or stones on adjacent two backplanes support, for reducing the frictional resistance between push pedal when operation and the base plate, simultaneously in order to guarantee that push pedal is as far as possible along the center line operation of base plate and do not depart from base plate, on base plate, be processed with the push pedal groove, and in the push pedal groove, be provided with two along the raised line that is parallel to each other on the floor length direction, the height of raised line is lower than the height of two ends projection above the base plate, push pedal is carried on these two parallel raised lines, carries goods and slides on two parallel raised lines.

In order to prevent directly to wash away goods from the thermal-flame of top burner ejection, the height of top burner on the kiln wall is higher than the height of goods, but is lower than the kiln inner height of kiln wall, and the bottom burner is installed at the bottom of the kiln.

In order to prevent directly to wash away backplanes support and reduce flue gas recirculation flow resistance in the kiln from the thermal-flame of bottom burner ejection, the center line of the lateral clearance between the center line of bottom burner and adjacent two backplanes support (horizontal quirk promptly) point-blank.

The two ends of backplanes support are 0.1-0.2 rice from the spacing of kiln inner wall, and two adjacent backplanes support are the length of a base plate along the center distance of kiln length direction, and the width of base plate is identical with the width on backplanes support top.

Burner of the present utility model is with the direct heating product of thermal-flame of ejection, and owing to interlaced arrangement about top burner and the bottom burner, lateral clearance (promptly going up horizontal quirk) between flue gas pushes up by goods and kiln around driving from the thermal-flame of top burner ejection, and driving on every side from the thermal-flame that the bottom burner sprays, flue gas has formed strong section air-flow circulation by the lateral clearance between adjacent two backplanes support (promptly going up horizontal quirk), this has not only strengthened the heat convection of flue gas and goods, improved heat transfer efficiency, also make the more uniform temperature of section in the clinkering zone kiln, goods are heated evenly, and help goods to burn till the raising and the minimizing firing time of quality.The utlity model has the heat transfer efficiency height, can effectively guarantee the advantage that section temperature is even in the clinkering zone kiln, the raising goods burn till quality and output.

The specific embodiment

Below in conjunction with implement and the contrast accompanying drawing the utility model is described in further detail.

The utility model is by kiln body 11, top burner 10, bottom burner 5, push pedal 1, base plate 13 and backplanes support 14 are formed, kiln body 11 is by

kiln wall

3,6 form at the bottom of kiln top 9 and the kiln, kiln wall 3 inwalls with corundum porzite flame-proof brick 4 as liner, top burner 10 and bottom burner 5 are installed in the both sides of kiln wall 3, top burner 10 and bottom burner 5 are crisscross arranged up and down, the relevant position on top burner 10 and bottom burner 5 opposites be respectively equipped with run through kiln wall 3 on flame-observing hole 2 and following flame-observing hole 15, be installed at the bottom of the kiln on 6 by the brick backplanes support 14 that forms of building of corundum fireproof, material is that the base plate 13 of corundum matter is built by laying bricks or stones on adjacent two backplanes support 14, when reducing push pedal 1 operation and the frictional resistance between the base plate 13, simultaneously in order to guarantee that push pedal 1 is as far as possible along the center line operation of base plate 13 and do not depart from base plate 13, on base plate 13, be processed with push pedal groove 16, and in push pedal groove 16, be provided with two along the raised line 12 that is parallel to each other on base plate 13 length directions, the height of raised line 12 is lower than the height of two ends projection 17 above the base plate 13, push pedal 1 is carried on these two parallel raised lines 12, carries goods 7 and slides on two parallel raised lines 12.

In order to prevent directly to wash away goods 7 from the thermal-flame of top burner 10 ejection, the height of top burner 10 on kiln wall 3 is higher than the height of goods 7, but is lower than the kiln inner height of kiln wall 3, and bottom burner 5 is installed at the bottom of the kiln 6.

In order to prevent directly to wash away backplanes support 14 and reduce flue gas recirculation flow resistance in the kiln from the thermal-flame of bottom burner 5 ejections, the center line of the lateral clearance between the center line of bottom burner 5 and adjacent two backplanes support 14 (horizontal quirk 18 promptly) point-blank.

The two ends of backplanes support 14 are 0.1-0.2 rice from the spacing a of kiln wall 3 inwalls, and two adjacent backplanes support 14 are the length of a base plate 13 along the center distance b of kiln length direction, and the width c of base plate 13 is identical with the width d on backplanes support 14 tops.

Top of the present utility model burner 10 and bottom burner 5 are with the direct heating product 7 of thermal-flame of ejection, and because top burner 10 and bottom burner interlaced arrangement about in the of 5, flue gas pushes up lateral clearance (promptly going up horizontal quirk 8) between 9 by goods 7 and kiln around driving from the thermal-flame of top burner 10 ejection, and driving on every side from the thermal-flame that bottom burner 5 sprays, flue gas has formed strong section air-flow circulation by the lateral clearance between adjacent two backplanes support 14 (promptly going up horizontal quirk 8), not only strengthened the heat convection of flue gas and goods 7, improved heat transfer efficiency, also make the more uniform temperature of section in the clinkering zone kiln, goods 7 are heated evenly, and help goods 7 to burn till the raising and the minimizing firing time of quality.
