Abstract

The utility model belongs to the technical field of metallurgical equipment, and particularly relates to a novel sintering machine grate bar, which comprises a grate bar body, limit blocks, limit studs and hooks disposed on the lower portion of the grate bar. The novel sintering machine grate bar is characterized in that the width of the grate bar body ranges from 70mm to 280mm, four to sixteen ventilation holes are arranged on the upper surface of the grate bar body, and the width of each hook is 0.5-2 times of the width of the grate bar body. Compared with the prior art, since the total width of the grate bar is twice or multiple times the width of an existing single grate bar structure, geometric progression of used grate bar number of single trolleys is reduced, and mounting workload is reduced. Further, the ventilation holes are arranged on the surface of the grate bar, ventilation of trolley surface is increased greatly, and accordingly sintering efficiency is increased, energy consumption is reduced and yield and finished product rate are both increased.

Description

Novel sintered machine grate bar

Technical field

The utility model belongs to the agglomerating plant technical field, particularly a kind of novel sintered machine grate bar.

Background technology

Sintering machine is the capital equipment of SINTERING PRODUCTION.Sintering machine grate bar is mounted on the pallet, and in order to the supporting material, and the critical component of material sintering is finished in the perforate ventilation.The basic structure of the grate strip that present domestic sintering pallet adopted comprises grate bar body substantially, limited block, and banking pin, the hook of grate bar bottom, at work, many grate bars are laid on the chassis continuously, form the sintering working face; Its limited block plays the adjacent grate stripe pitch of restriction as the vent passages effect; During backhaul, grate bar bottom hangs on the chassis girder, prevents that the grate bar from dropping.Though the grate bar of this structure can satisfy the demand of SINTERING PRODUCTION technology, also exist not enough: grate bar quantity is many on the separate unit chassis, and installation workload is big; Ventilative rate is not high, influences sintering efficient; Problems such as Unit Weight rigidity is not high.

Summary of the invention

It is few that the purpose of this utility model provides a kind of separate unit chassis grate bar quantity, ventilative rate height, and the novel sintered machine grate bar of Unit Weight good rigidity.

The objective of the invention is to realize by following technical proposals:

According to sintering machine grate bar of the present utility model, comprise grate bar body, limited block, limited post nail, be arranged on the hook of grate bar bottom, the width that it is characterized in that described grate bar body is 70-280mm, have air-permeating hole at described grate bar body upper surface, described hook width is 0.5-2 a times of grate bar body width.

The air-permeating hole that described grate bar body upper surface is opened is 4～16.

The beneficial effects of the utility model are:

Compared with prior art, because grate bar overall width is 70-280mm, be 2 times or many times of existing single grate bar structure, make the separate unit chassis use the geometric progression of grate bar quantity to descend, installation workload reduces, and the air-permeating hole that has of grate bar surface, improved the ventilative rate in chassis surface greatly, thereby improved sintering efficient, cut down the consumption of energy, increased output and yield rate; Because the width of grate bar bottom hook is 0.5-2 a times of grate bar body width, and its width is equivalent to grate bar middle part width, reduced grate bar hook weight proportion effectively in addition, made the grate bar of equal rigidity, comparable existing structure grate bar weight reduces greatly.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, sintering machine grate bar of the present utility model, comprise grate bar body 1, limited block 2, limited post nail 4, be arranged on the hook 3 of grate bar bottom, the width that it is characterized in that described grate bar body 1 is 70-280mm, have air-permeating hole 5 at described grate bar body 1 upper surface, described hook width is 0.5-2 a times of grate bar body width.

As flexible realization of the present utility model, the air-permeating hole that described grate bar body upper surface is opened can be split into 4～16 according to the width of grate bar body 1.Improve ventilative rate effectively, thereby improved sintering efficient, cut down the consumption of energy, increased output and yield rate.

Claims

1. novel sintered machine grate bar, comprise grate bar body, limited block, limited post nail, be arranged on the hook of grate bar bottom, the width that it is characterized in that described castor bar body is 70-280mm, have air-permeating hole at described grate bar body upper surface, described hook width is 0.5-2 a times of grate bar body width.

2. novel sintered machine grate bar according to claim 1 is characterized in that the air-permeating hole that described grate bar body upper surface is opened is 4～16.
