Abstract
The utility model relates to the field of rotary kilns, in particular to an anchor nail welding mode which is used to prevent refractory casting material of a front kilneye of the rotary kiln from flaking off, which comprises a kiln cylinder body, wherein a brick retaining ring is arranged on the inner wall of the kiln cylinder body, a refractory steel guard board with an angle of approximate 90 degrees is arranged on the end portion of the inner wall of the kiln cylinder body, arch nails are respectively welded on the end surface of the kiln cylinder body and the end surface and the side face of the refractory steel guard board, and an anchor nail is further arranged on the position with an angle of approximate 90 degrees of the refractory steel guard board. The utility model has the beneficial effects that the welding mode can reduce the integral flaking and scouring of the casting material of the front kilneye, increases the service life of the refractory casting material, and has simple structure and easy manufacturing and construction only by further welding the anchor nails on key positions.
Description
Technical field
The utility model relates to the rotary kiln field, especially a kind of anchor studs welding manner that prevents that the preceding kilneye fire resistant pouring material of rotary kiln from peeling off.
Background technology
Kilneye comprises by heat resisting steel backplate, anchor studs, castable refractory, kiln cylinder body before the rotary kiln, is one of worst equipment of working environment in the rotary kiln, is subjected to washing away and corroding of high-temperature material for a long time.At present, preceding kilneye anchor studs mainly is to be welded on heat resisting steel backplate end face and side and the part kiln cylinder body, and welding manner adopts to intersect and welds, and spacing is between 150～200mm.But, anchor studs is welded on the end face and side of heat-resisting steel sheet and plate, can not connect well and water material feeding and heat resisting steel backplate, the castable refractory of preceding kilneye weares and teares easily, even integral body is peeled off, when the castable refractory well damage, preceding kilneye will deform, and causes very big difficulty for production and maintenance.
The utility model content
The technical problems to be solved in the utility model is: for the deficiency of wearing and tearing with large tracts of land of peeling off of kilneye fire resistant pouring material integral body before overcoming, the utility model provides a kind of preceding kilneye of rotary kiln, changed the preceding kilneye anchor studs welding manner of this rotary kiln, thereby the integral body that has reduced castable refractory is peeled off, but also has improved the wearability of castable refractory greatly.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of preceding kilneye of rotary kiln, has kiln cylinder body, the kiln cylinder body inwall is provided with check ring for blocking bricks, the close end of kiln cylinder body inwall is provided with the heat resisting steel backplate of nearly an angle of 90 degrees, the end face and the side of the end face of kiln cylinder body and heat resisting steel backplate are welded with anchor studs, and the nearly an angle of 90 degrees of described heat resisting steel backplate place is welded with an anchor studs.
For the refractory brick that prevents to tilt to watering the pressure influence of material feeding, on check ring for blocking bricks, also add weldering one anchor studs.
Describedly be welded on anchor studs on the check ring for blocking bricks perpendicular to the center line of kiln cylinder body, and evenly be spaced on the ring surface of check ring for blocking bricks, spacing is 170mm.
The described anchor studs that is welded on kiln cylinder body and the heat resisting steel backplate is staggered on preceding kilneye is axial, and spacing is 150～200mm.
The beneficial effects of the utility model are: the integral body that the preceding kilneye of minimizing waters material feeding is peeled off and washed away, and has improved the service life of castable refractory, and has just added the weldering anchor studs at key position, and is simple in structure, is easy to production and construction.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of kilneye before the general rotary kiln.
Fig. 2 is the structural representation of the preceding kilneye of rotary kiln in the utility model.
Among the figure: 1. kiln cylinder body, 2. heat resisting steel backplate, 3. check ring for blocking bricks, 4. anchor studs.
The specific embodiment
Kilneye anchor studs 4 welding positions as shown in Figure 1 before the general rotary kiln, anchor studs 4 mainly is welded on the end face and the side of the end face and the heat resisting steel backplate 2 of kiln cylinder body 1, but on heat resisting steel backplate 2 nearly an angle of 90 degrees places and check ring for blocking bricks 3, generally do not weld anchor studs 4, and this part washes away the most serious zone exactly, waters material feeding integral body and peels off from this.
In the utility model, the structure of preceding kilneye and anchor studs 4 welding positions are as shown in Figure 2, a kind of preceding kilneye of rotary kiln, has kiln cylinder body 1, kiln cylinder body 1 inwall is provided with check ring for blocking bricks 3, the end of kiln cylinder body 1 inwall is provided with the heat resisting steel backplate 2 of nearly an angle of 90 degrees, the end face of the end face of kiln cylinder body 1 and heat resisting steel backplate 2 and side are welded with anchor studs 4, described heat resisting steel backplate 2 nearly an angle of 90 degrees places are welded with an anchor studs 4, be welded on anchor studs 4 axially being staggered on kiln cylinder body 1 and the heat resisting steel backplate 2 at preceding kilneye, spacing is 150～200mm, and the anchor studs 4 that is welded on the check ring for blocking bricks 3 evenly is spaced on the ring surface of check ring for blocking bricks 3, and spacing is 170mm.
Claims (4)
