Description
Technical field
The utility model belongs to the sintering pallet technical field of metallurgy industry, relates in particular to a kind of sintering machine stillage truck joined grid.
Background technology
The sintering machine bogie grates of prior art is a monomer, generally includes a grid section body, connects the grid section hook of two c-shaped shapes at the downside of grid section body, and above-mentioned monomer grid section is finished by disposable hot investment casting.The both ends of the surface of grid section body are and grid section body upper side vertical rectangular plane.The monomer grid section of many said structures is arranged continuously and is installed on the car body of sintering pallet, leaves suitable ventilative slit between the grid section, thereby constitutes the sintering machine siege.Work under bad working environments conditions such as high-temperature oxydation, flue gas corrosion, cold and hot temperature difference alternation, temperature distributing disproportionation, local burning, the grid section consumption of said structure is by norm: 0.05～0.09kg/t (grid section consumption/sintering deposit output).
Since the nearly more than ten years, SINTERING PRODUCTION technological progress development rapidly, generally adopt ripe big air quantity, the intensified-sintered production of high negative pressure new technology, technological measures such as for example deep-bed sintering, raising material temperature, reinforcement are granulated, employing quick lime, heat storage capacity is increased substantially, and SINTERING PRODUCTION is significantly improved.But, along with improving constantly of heat storage capacity, cause the further deterioration of high temperature to the grid section work condition environment, subtract under the situation of chi, local burning, the further aggravation of flexural deformation in the grid section scaling loss simultaneously, the grid section consumption is multiplied, and approximately is about 2～3 times of consumption quota 0.05～0.09kg/t.Particularly thermal change causes the bending of arching upward of grid section middle part, and thermal stress is concentrated and caused the grid section fracture, and the grid section of fracture comes off, and causes chassis to leak material, leak out, and then needs to carry out frequent shutdown and changes, and has a strong impact on SINTERING PRODUCTION efficient.Yet, cause the big main cause of grid section consumption as follows: the one, the ventilative rate of siege is little, and resistance is big, the easily inclined to one side wind of siege; The 2nd, structurally there is the defective of intensity difference in grid section, and is incompatible with the heat storage capacity of the sintering new technology of big air quantity high negative pressure; The 3rd, increasing grid section intensity thickening cross dimensions is two aspects of contradiction with the total slit of limited siege amount (ventilative rate), but the two can not be inclined to one side one, so the present solution that does not search out as yet.In order to strengthen the grid section flexural strength, the most common improving one's methods is to thicken, increase the grid section cross dimension.Though said method is improved the intensity of grid section, rigidity, anti-fracture energy is enhanced, and this grid section is laid particular stress on and improved grid section intensity, ignores ventilative rate.Thickening grid section cross dimensions has taken limited total ventilative slit amount, and for example, the ventilative rate of four main beam structure sintering pallets drops to 10.38% by the 11.16% ventilative rate that drops to 9.13%, three main beam structure sintering pallet by 14.07%.The decline of ventilative rate influences SINTERING PRODUCTION efficient.In order to increase ventilative rate, can change the girder of trolley body structure into three by four, the frittedhearth grid section changes two rows into by three rows.The ventilative space of this body construction increases to some extent, and ventilative rate makes moderate progress, and the intensity of grid section is taken into account to some extent.But, since the minimizing of trolley body girder, the grid section length that must extend, the also essential corresponding thickening in grid section cross section, but this can make the ventilative rate of grid section be restricted again.So the raising of ventilative rate of grid section and intensity is very limited.
The utility model content
Technical problem to be solved in the utility model provides a kind of intensity height, the ventilative big sintering machine stillage truck joined grid of rate.
The utility model comprises the grid section body, connects the grid section hook on the downside of grid section body, and described grid section body comprises at least two independent grid section bodies, and above-mentioned at least two independent grid section bodies are arranged side by side, and independent grid section body forms vertical ventilative gap each other at interval; Be provided with between the independent grid section body the interconnective a plurality of conjuncted muscle of independent grid section body, form box-structure.
As improvement of the present utility model, a plurality of grooves that are parallel to each other are set on the working face of each independent grid section body, each groove tilts with respect to the working face axis of independent grid section body.
Improve again as of the present utility model, be herringbone along the section of the inside grooves of groove length direction.
As further improvement of the utility model, groove is curved on its length direction, and groove is up-narrow and down-wide.
As improvement of the present utility model, the two ends of each independent grid section body are respectively intilted inclined-planes, and the two ends between independent grid section body and the independent grid section body form ventilation slot respectively.
As improvement of the present utility model, boss is set respectively on the two sides of grid section body.
Compare with the monomer grid section of prior art, the box-structure that conjuncted grid section is combined as a whole side by side and formed by many monomer grid sections, its sectional area increases, and can reduce the section thickness of each the grid section body in conjuncted thus, thereby significantly increase the total slit of frittedhearth amount (ventilative rate).This has not only enlarged ventilative rate; simultaneously the intensity of conjuncted grid section, rigidity, counter-bending, ability significantly improve; prolonged the service life of grid section; avoided effectively causing Lou material, air leakage phenomena because of the grid section breaking releasing; reduce frequent shutdown and change grid section, reduce consuming, having improved SINTERING PRODUCTION efficient.A plurality of grooves are set on the working face of conjuncted grid section, form the transversal ventilation mouth, opened up another ventilative passage, having broken the direction of letting in air in the prior art only is the situation of single vertical direction, reduce flowing resistance, overcome the defective of the inclined to one side wind of siege, further increased substantially the ventilative rate of pallet siege.Thus, solved contradiction between the total slit of grid section intensity and the limited frittedhearth amount (ventilative rate) effectively.To become herringbone along the Section Design of the inside grooves of groove length direction, be for discharge smoothly when ventilating, and prevents that sintering feed from stopping up the groove ventilating opening.Furthermore, groove is designed to arc on its length direction be in order to improve the groove bulk strength, and it then is in order to make discharge more smooth and easy that groove design becomes up-narrow and down-wide form.The two ends of each independent grid section body are designed to intilted inclined-plane, and the two ends between independent grid section body and the independent grid section body form ventilation slot respectively, have changed the complete nonventilated defective in grid section two ends in the prior art, have significantly reduced flowing resistance.On two lateral surfaces of conjuncted grid section boss being set respectively, is to form vertical ventilative gap when being arranged on the siege for conjuncted grid section between conjuncted grid section.The disposable hot investment casting of this conjuncted grate strip adoption is finished.
