Abstract

The invention relates to a push head of an active lime pre-heater. The push head is in a cuboid box type structure, reinforcing ribs arranged in a staggered way are arranged in the push head of the pre-heater, technique holes are arranged in the lower bottom surface of the push head of the pre-heater, and a rear end of the push head of the pre-heater is provided with a hinged plate. The push head is stable in structure, is economic and practical and does not cause deformation and crack under a high-temperature using state.

Description

A kind of quickened lime preheater is cut somebody's hair

Technical field

The present invention relates to quickened lime, forge bulk or the granular material roasting technology field such as white, light dolomite, particularly relate to a kind of material-pulling device of quickened lime preheater.

Background technology

A kind of energy-efficient equipment that the bulk such as preheater is quickened lime, it is white to forge, light dolomite or granular material calcination rotary kiln system generally adopt, cutting somebody's hair is the material-pulling device of preheater.Used preheater is cut somebody's hair and mostly is the steel casting of half box structure at present, and structural stability is poor, and resistance to shear is poor, easily occurs the phenomenons such as distortion, cracking under the applied at elevated temperature state, has a strong impact on the work-ing life of cutting somebody's hair, and has affected production, has increased production cost.

Summary of the invention

In order to overcome the shortcoming of prior art, the invention provides a kind of quickened lime preheater and cut somebody's hair, its Stability Analysis of Structures, economical and practical, indeformable under the applied at elevated temperature state, do not ftracture.

The present invention solves the technical scheme that its technical problem takes: preheater is cut somebody's hair and is that there is the stiffening web of staggered arrangement the box structure of rectangular parallelepiped, the preheater inside of cutting somebody's hair, on the bottom surface that preheater is cut somebody's hair fabrication hole is arranged, and there is articulated slab the rear end that preheater is cut somebody's hair.

Stability Analysis of Structures of the present invention, economical and practical, indeformable under the applied at elevated temperature state, do not ftracture.Improve 2-3 work-ing life doubly, reduced maintenance downtime, saved production cost, improved labour productivity.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is front view of the present invention;

Fig. 2 is vertical view of the present invention;

Fig. 3 is left view of the present invention;

Fig. 4 is the A-A sectional view among Fig. 3 of the present invention;

Fig. 5 is that the present invention uses state reference map.

Embodiment

Shown in Fig. 1-4, the present invention is the box structure of rectangular parallelepiped, and very strong resistance to shear is arranged under the state of discontinuity equalization.There is the stiffening web 4 of staggered arrangement preheater 1 inside of cutting somebody's hair, has both increased the bulk strength of cutting somebody's hair, and has reduced again producing the possibility of organizing shrinkage porosite in the making processes.Preheater is cut somebody's hair has fabrication hole 2 on 1 the bottom surface, reduces cost of manufacture.There is articulated slab 3 cut somebody's hair 1 rear end of preheater.

As shown in Figure 5, preheater is lower in working order, is full of material in the body of chamber, and air-flow and material reversing motion are so that material fully preheating in preheater.Gas flow temperature is about about 1000 ℃, so built refractory materials in the preheater by laying bricks or stones.Preheater 1 push mechanism as material movement in the preheater of cutting somebody's hair, drive door type frame 5 by hydraulic ram 7, two tail rods 6 are housed on the door type frame 5, it is 1 hinged that tail rod 6 and preheater are cut somebody's hair, tail rod 6 is controlled cut somebody's hair 1 travel direction of preheater, and provides power for cut somebody's hair 1 motion of preheater.

Claims

1. a quickened lime preheater is cut somebody's hair, it is characterized in that: preheater is cut somebody's hair (1) for the box structure of rectangular parallelepiped, there is the stiffening web (4) of staggered arrangement preheater (1) inside of cutting somebody's hair, preheater is cut somebody's hair has fabrication hole (2) on the bottom surface of (1), and there is articulated slab (3) the cut somebody's hair rear end of (1) of preheater.
