Abstract

The utility model relates to an active lime preheater pushing head. The preheater pushing head is of a rectangular box-type structure, reinforcing ribs are arranged in the preheater pushing head in a staggered mode, the lower bottom surface of the preheater pushing head is provided with a process hole, and the rear end of the preheater pushing head is provided with a hinge plate. The active lime preheater pushing head disclosed by the utility model is stable in structure, economical and practical, and is not deformed and cracked in a high-temperature usage state.

Description

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

Technical field

The bulk such as the utility model relates to quickened lime, it is white to forge, light dolomite or granular material roasting technology field 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.Preheater used 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 utility model provides a kind of quickened lime preheater to cut somebody's hair, and its Stability Analysis of Structures is economical and practical, and is indeformable under the applied at elevated temperature state, do not ftracture.

The technical scheme in the invention for solving the technical problem is: 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.

The utility model Stability Analysis of Structures, 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

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is the utility model front view;

Fig. 2 is the utility model vertical view;

Fig. 3 is the utility model left view;

Fig. 4 is the A-A sectional view in the utility model Fig. 3;

Fig. 5 is that the utility model uses state reference map.

Embodiment

As shown in Fig. 1-4, the utility model 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 making processes.Preheater is cut somebody's hair has fabrication hole 2 on 1 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 in working order under, be full of material in the body of chamber, air-flow and material reversing motion make material fully preheating in preheater.Gas flow temperature is about 1000 ℃ of left and right, so built refractory materials in preheater by laying bricks or stones.Preheater 1 push mechanism as material movement in preheater of cutting somebody's hair, drive door type frame 5 by hydraulic ram 7, two tail rods 6 are housed on 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) preheater the cut somebody's hair rear end of (1).
