Abstract
A rotary kiln capable of preventing blown sand from damaging kiln head equipment comprises a kiln head cover, a wheel belt, a barrel, an air cooling sleeve, a graphite block sealing device, a labyrinth seal, a kiln cover and kiln opening back iron. The rotary kiln further comprises a horn-shaped striker plate arranged on the outer surface of the barrel and placed between the wheel belt and the air cooling sleeve, a graphite block sealing paste board arranged on the outer surface of the air cooling sleeve and placed on the contact area of the air cooling sleeve and the graphite block sealing device, a kiln opening sealing plate arranged on the outer surface of the air cooling sleeve and placed on the edge of the kiln opening back iron, and gap filler arranged in a gap formed by the outer surface of the air cooling sleeve and the inner surface of the kiln opening back iron. According to the technical scheme, the technical problems that the abrasion of the position where the outer surface of the air cooling sleeve is placed on the contact area of a sealed graphite block and the air cooling sleeve is serious, the abrasion between the wheel belt and supporting wheels is quite serious, and damage can happen easily due to the fact that kiln head blown sand materials overflow in the working process of the rotary kiln are solved, the service life of the air cooling sleeve, the wheel belt and the supporting wheels is improved, the maintaining cycle is prolonged, the maintaining cost is lowered, and maintaining is convenient and fast.
Description
Technical field
The invention belongs to rotary kiln device technical field, be specifically related to a kind of rotary kiln that prevents blown sand infringement kiln hood equipment.
Background technology
Rotary kiln kiln hood when work can produce more blown sand material, one grade of wheel band and kiln hood are sealed to air-cooled cover etc. and caused infringement to a great extent, blown sand material makes air-cooled cover be positioned at the serious wear of sealed graphite piece and air-cooled cover contact position, fall the blown sand material between one grade of wheel band and support roller, also make wheel band and support roller surface abrasion quite serious.Therefore, when existing rotary kiln exists work, kiln hood blown sand material overflows seriously, makes air-cooled cover outer surface be positioned at serious wear and wheel band and the quite serious technical problem of support roller surface abrasion of sealed graphite piece and air-cooled cover contact position.
Summary of the invention
While the object of the invention is to solve existing rotary kiln work, kiln hood blown sand material overflows seriously, cause air-cooled cover outer surface to be positioned at serious wear and the flimsy technical problem of wheel band and support roller surface of sealed graphite piece and air-cooled cover contact position, a kind of rotary kiln that prevents blown sand infringement kiln hood is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of rotary kiln that prevents blown sand infringement kiln hood equipment, comprise kiln head cover, wheel band, cylindrical shell, air-cooled cover, graphite block sealing device, labyrinth seal, kiln head cover and kilneye cap iron, wherein, it also comprises tubaeform striker plate, graphite block sealing subsidy plate, kilneye sealing plate and gap-filler shall, described tubaeform striker plate is located on barrel outer surface, between wheel band and air-cooled cover and near a side of taking turns band; Described graphite block sealing subsidy plate is located on cold wind shroud outer surface and is positioned at the region that cold wind shroud contacts with graphite block sealing device; Described kilneye sealing plate is located on cold wind shroud outer surface and is positioned at the edge of kilneye cap iron; Described gap-filler shall is located in the gap of cold wind shroud outer surface and kilneye cap iron inner surface formation.
Described graphite block sealing subsidy plate and kilneye sealing plate are the corrosion resistant plate that 8～10mm is thick.
Described gap-filler shall is alumina silicate fiber felt.
Because the present invention has adopted technique scheme, it is quite serious and be easy to the technical problem of damage that while having solved rotary kiln work, kiln hood blown sand material overflows the wearing and tearing between the serious wear of sealed graphite piece and air-cooled cover contact position and wheel band and support roller of the air-cooled cover outer surface that causes, compare with background technology, the present invention has a large amount of kiln hood blown sand material that reduced and overflows, reduced and fallen into blown sand material between wheel band and support roller, the wearing and tearing of cold wind shroud outer surface and wheel band and support roller have been slowed down, improved cold wind shroud, the service life of wheel band and support roller, increase maintenance period, reduce maintenance cost, the advantage such as quick easy to maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1---wheel band, 2---cylindrical shell, 3---tubaeform striker plate, 4---air-cooled cover, 5---graphite block sealing subsidy plate, 6---graphite block sealing device, 7---labyrinth seal, 8---kiln head cover, 9---kilneye sealing plate, 10---gap-filler shall, 11---kilneye cap iron.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, the rotary kiln that prevents blown sand infringement kiln hood equipment in the present embodiment, comprise that kiln head cover, wheel are with 1, cylindrical shell 2, air-cooled cover 4, graphite block sealing device 6, labyrinth seal 7, kiln head cover 8 and kilneye cap iron 11, wherein, it also comprises tubaeform striker plate 3, graphite block sealing subsidy plate 5, kilneye sealing plate 9 and the gap-filler shall 10 of using alumina silicate fiber felt to make, described tubaeform striker plate 3 is located on cylindrical shell 2 outer surfaces, wheel with 1 and air-cooled cover 4 between and near wheel with a side of 1; Described graphite block sealing subsidy plate 5 is located on cold wind shroud 4 outer surfaces and by cold wind shroud 4 and covers completely with the region that graphite block sealing device 6 contacts; Described kilneye sealing plate 9 is located on cold wind shroud 4 outer surfaces and is positioned at the edge of kilneye cap iron 11; Described gap-filler shall 10 is located in the gap of cold wind shroud 4 outer surfaces and kilneye cap iron 11 inner surfaces formations.Graphite block sealing subsidy plate 5 forms one by two parts at least and encloses.
This rotary kiln that prevents blown sand infringement kiln hood equipment is when work, and kilneye sealing plate 9 and gap-filler shall 10 have effectively reduced overflowing of kiln hood blown sand material; Graphite block sealing subsidy plate 5 forms a circle by two parts at least, make graphite block sealing device 6 cold wind shroud 4 that directly do not wear and tear, and this graphite block sealing subsidy plate 5 is easy to replacing; Tubaeform striker plate 3 can effectively stop blown sand material, has reduced greatly the blown sand material falling between wheel band and support roller, has alleviated between wheel band and support roller and has worn and torn, and has improved service life.
The present invention is not limited to the embodiment in above-described embodiment, so long as the rotary kiln that prevents blown sand infringement kiln hood equipment of bag striker plate, graphite block sealing subsidy plate, kilneye sealing plate and gap-filler shall all falls into protection scope of the present invention.
