Abstract

The utility model relates to an enhanced-draining filtrating device of steel slag thermo-smoldering equipment. The enhanced-draining filtrating device comprises a grid plate A, wherein a grid plate B is arranged at a position, which is 300mm away from the grid plate A, in the inner side direction of the rear end of the grid plate A, the grid plate A and the grid plate B are welded through four round steel bars in all, namely an upper round steel bar, a lower round steel bar, a left round steel bar and a right round steel bar, so as to form a three-dimensional columnar filtrating device, a square snap buckle which is used for preventing the grid plate B from sliding downwards is welded to the back of the grid plate B, and a gap, through which the entire filtrating device can be conveniently taken out through a hook and cleaned, is formed in the top of the grid plate A. The enhanced-draining filtrating device has the characteristics that the probability of the occurrence of potential safety hazards, such as explosion and the like, during production is lowered, the labor intensity for laborers is lowered, and the production efficiency is increased.

Description

A kind of enhancement type discharge filtering device of steel slag hot disintegrating equipment

Technical field

The utility model relates to filtration unit field, relates in particular to a kind of double-deck grate plate design that adopts, middle with round steel welding, makes it the enhancement type discharge filtering device of the steel slag hot disintegrating equipment that becomes a tubular.

Background technology

Along with the aggravation of resource consumption, people more and more pay attention to various solid waste resource recovery utilizations.Slag is in steelmaking process, to produce maximum solid waste, slag recycling become and affected Iron and Steel Production and environment, one of important factor of social harmonious development.Steel slag hot disintegrating treatment process has been taken into account the stable and environmental requirement of slag performance, more and more general in the application of each big steel enterprise in recent years.

Referring to Fig. 1 and Fig. 2, the main equipment of steel slag hot disintegrating technique is cold stoking, and the drainage pipeline 12 of cold stoking is a most important ring of water cycle in whole technique.

Before cold stoking slag input; after grate plate 11 places; conventionally to cover a large slag steel 12 mouthfuls of drainage pipelines and be used for stopping that bulk slag enters drainage pipeline 12; protection grate plate 11 can directly not contact high-temperature steel slag; reducing grate plate 11 is out of shape, blocks; in whole vexed slag process, guarantee that so not vaporized water can discharge through drainage pipeline, can not cause cold stoking ponding, to such an extent as to it is dangerous can not blast etc.

The subject matter that current this water-freeing arrangement exists is in actual use:

Although 1 whole grate plate 11 does not directly contact high temperature furnace slag, but because the whole vexed slag activity duration is grown (approximately 12 hours), grate plate 11 still has distortion in various degree, when after grate plate 11 distortion, can directly be poured in drainage pipeline 12, not have the effect of filtration.

2, after grate plate 11 is poured on buckle 13 backward, cold stoking is fetched water flow when larger, and grate plate 11 can be rushed in drainage pipeline 12, causes grate plate 11 to lack, or even drainage pipeline 12 blocks, and has certain production safety hidden danger.And the other end of drainage pipeline 12 seals (only leaving water outlet) with steel plate, the artificial comparatively trouble of taking out.

3, due to the defect of this device, force workman to complete at every turn and come out of the stove after operation, all must clear up whole drainage pipeline, check.Whole process labour intensity is large, and operating environment poor (temperature is high, atmosphere draught-free), easily causes security incident.

Utility model content

In order to overcome the above-mentioned shortcoming of prior art, it is a kind of with double-deck grate plate design that the utility model provides, weld with round steel centre, solve the steel slag hot disintegrating stove problem that drainage pipeline blocks in process of production, reduce the probability of potential safety hazards such as blasting in production process, reduce people's labour intensity, enhanced productivity, there is the enhancement type discharge filtering device of the steel slag hot disintegrating equipment of higher using value.

The utility model solves the technical scheme that its technical problem adopts: a kind of enhancement type discharge filtering device of steel slag hot disintegrating equipment, comprise a grate plate A, be provided with a grate plate B in grate plate A rear inside direction apart from grate plate A300mm place, between grate plate A and grate plate B, pass through up and down the filtration unit of a three-dimensional tubular of totally four round steel welding formation, after grate plate B, weld one for stoping the square buckle of its down sliding, offer a breach that facilitates whole filtration unit hook to take out and clear up at described grate plate A top.

Described grate plate A and grate plate B diameter are 310mm.

On described grate plate A and grate plate B, be provided with the filter pore that several diameters are 10mm.

Be provided with water shoot road junction at the front end of described grate plate A.

Described breach high for 25mm width be 20mm.

The beneficial effects of the utility model are: adopt double-deck grate plate design, weld with round steel centre, make it to become " tubular " filtration unit, overcome the problem that grate plate is toppled over, improved the effect of filtering, also greatly reduced workman's labour intensity, enter stokehold only need check water port at every turn, there is the probability that has reduced potential safety hazards such as blasting in production process, reduced people's labour intensity, the feature of enhancing productivity.
