By virtue of the novel structure, the utility model overcomes the defects existing in the prior art, and particularly has the advantages of high flour dust trapping efficiency, low energy consumption, low failure rate and the like.
Description
Technical field
The utility model relates to the dedusting field of the hot drawing annealing unit (being called for short CT unit or AT unit, also is oriented silicon steel final finished unit) of producing oriented silicon steel, is specifically related to a kind of magnesia dedusting system of oriented silicon steel hot drawing annealing set.
Background technology
CT (hot drawing annealing) unit is last procedure of orientation silicon steel production technology.The dust-removal system of its entrance is a difficult problem of puzzlement designing unit and production unit always, mainly shows as:
1. collection efficiency is low, and dust is piled up easily and can't be taken away.
2. take out the dirt pits position and be difficult to determine, because the motion of equipment is interfered, the dynamic change of coil of strip diameter is taken out dirt and is difficult to determine the optimum position.
3. system design is huge, the energy consumption height, and level of automation is low, the failure rate height, production efficiency is low on the contrary.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of magnesia dedusting system of oriented silicon steel hot drawing annealing set is provided, and this dust-removal system can overcome the defective that prior art exists.
The technical scheme that its technical problem of solving the utility model adopts is: comprise operated pneumatic valve, fly-ash separator, blower fan, take out the dirt pits capturing device, take out dust hood, air curtain curtain and defeated grey equipment.Wherein: take out the dirt pits capturing device and the air curtain curtain is contained in Abrollhaspel and inlet is cut the place, and be connected to fly-ash separator, blower fan by operated pneumatic valve and air line; Defeated grey equipment is positioned at the fly-ash separator bottom, is responsible for that fly-ash separator is cleared up the magnesium oxide dust that gets off and walks clearly.
The utlity model has following main advantage:
1. take out the method for arranging that dirt pits " is tried by hook to seek ": top is taken out dirt pits and is captured owing to be with steel disturbance, the elegant aerial dust of multiple reason such as equipment vibrations.The bottom is taken out dirt pits and is captured the dust that reasons such as magnesium oxide caking or coil of strip expansion are fallen downwards.This design biggest advantage is exactly with strong points, and take stopgap measures, takes out dirt pits near the dust production resource point.Avoid designing in the past in a large space and establish half-sealed cover, induced exhaust is arranged on the enclosed hood, and dust is produced the very little shortcoming of draft.
2. taking out dust hood " is association of activity and inertia ": the product dirt pits to equipment is divided into moving point and dead point, and the corresponding dust hood of taking out also divides dynamic cover and static cover into.Dynamically cover is driven by cylinder or frame, so that the best approaching dirt pits that produces.Because the variability that unit equipment allows, the static cover of employing simply is well to follow the tracks of the dirt source point of mobility, and for this complex working condition, adopting dynamically, cover is a kind of good terms of settlement.But dynamically the design of cover and remarkable need be taken all factors into consideration all respects situation, and the dynamic cover of native system is that a kind of two dimension is dynamically covered, and it can realize the swing function in company with the variation of coil of strip coil diameter, can also realize following the tracks of longitudinally according to coil of strip sideslip situation simultaneously.
3. at dirt source point situation " pressure-vaccum combination ": escape for avoiding dust, observing and operate for equipment simultaneously provides the good visual field, and system adopts air curtain technology, by high speed blowing and efficient exhausting combination, provides the dedusting gas curtain.The air curtain curtain is a kind of extraordinary mode, when equipment can't carry out mechanical close, blocks airflow space.
4. system's automatic dynamic is switched: design has operated pneumatic valve on system pipeline, and according to equipment in working order whether, (or time-delay) opening-closing valve to reduce system scale, cuts down the consumption of energy automatically.
5. design the short defeated grey equipment that hangs of outboard bearing, failure rate is low.Intrinsic defeated grey equipment is the major axis design, and split bearing is positioned at cinder conveyer, and failure rate is very high like this.Should will fail grey design bearing in the cinder conveyer outside by defeated grey equipment, main shaft is not yielding, and bearing is arranged in the air of cleaning, and failure rate greatly reduces.
In a word, therefore the utility model can overcome the defective that prior art exists owing to have novel structure, especially has advantages such as the dust of capture efficient height, energy consumption and failure rate are low.
