Description
Technical Field
The utility model belongs to the technical field of the grate, concretely relates to special reciprocating grate for kiln.
Background
A boiler or an industrial furnace is a unit for stacking and efficiently burning solid fuel. The whole fire grate mainly comprises a frame and a fire grate segment. The grate segments are usually made of cast iron, the necessary ventilation gaps are maintained between the segments after assembly, and separate ventilation chambers capable of adjusting air volume are arranged below the grate so that air can enter the fuel layer through the gaps for combustion. The burnt ash is discharged by manual or mechanical method. The grate can be of fixed type, movable type, reciprocating type, vibrating type, underfeed type and the like.
The existing grate adopts a traditional structure, so that the heat resistance is poor, and the problem that excess materials of an industrial kiln cannot be fully combusted and cooled due to the changeability of a grate beam is solved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a special reciprocating grate for kiln to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a special reciprocating grate for kiln, includes outer protecting casing, a plurality of grate segments are installed to outer protecting casing's inboard, the grate segment is driven by hydraulic drive device, hydraulic drive device comprises hydraulic stem and drive mechanism and runner, the grate segment specifically is the leak protection grate segment of fire brick material, the cross-section of leak protection grate segment is predetermined shape, and fixed reciprocating grate beam or the reciprocating grate beam of activity are installed to the bottom of leak protection grate segment.
Further, the predetermined shape is a dogleg shape.
Furthermore, the fixed reciprocating grate beam and the movable reciprocating grate beam are designed to be tubular with hollow middle parts.
Further, the pipe walls of the fixed reciprocating grate beam and the movable reciprocating grate beam are larger than 3 cm.
Furthermore, the fixed reciprocating grate beam and the movable reciprocating grate beam are made of stainless steel.
Compared with the prior art, the beneficial effects of the utility model reside in that:
1. the leak-proof fire grate segment made of refractory brick materials can improve the heat-resisting effect, and the broken line design can increase the contact area with air, so that the heat dissipation effect is improved.
2. The fixed reciprocating grate beam and the movable reciprocating grate beam are made of stainless steel materials, the severe environment of the industrial kiln can be effectively coped with, and the hollow thick pipe wall structure is adopted, so that the air cooling efficiency is improved while the deformation of the reciprocating grate beam can be avoided, and great economic and social benefits are achieved.
