Description
Technical field
The utility model belongs to metal working technical area, is specifically related to the box firebreak device of a kind of thin plate rolling.
Background technology
In thin plate rolling processing, especially during rolling duralumin, hard alumin ium alloy, may raw edges be there is, be easy under tension broken belt occurs.In order to reduce the generation of broken belt, avoid destroying the stable of the operation of rolling, ROLLING OIL is recycled in rolling mill practice, reduce the friction between roll and metal forming, take away the deformation heat of metal, saponified in the impurity powder on clean metal surface and frame, thus realize stable rolling, improve the surface quality of sheet metal.
But because ROLLING OIL is flammable liquid, volatile, lightning is low, add that metal forming produces a large amount of heat in generation plastic deformation process, a large amount of mist of oils will inevitably be produced around rolling equipment, once run into burning things which may cause a fire disaster (electrostatic, spark, temperature are excessively high) to get final product breaking out of fire; Metal forming very easily loses electronics and brings electrostatic charge in friction process engineering in addition, there is disaster hidden-trouble.In rolling mill practice flow process, ROLLING OIL reflux cycle use again, if catch fire, the intensity of a fire can spread downwards to major accident along oil returning tube.
Utility model content
In order to reduce the hidden danger that in thin plate rolling process, fire occurs, the utility model provides the box firebreak device of a kind of thin plate rolling, stops fire spreading in time.
To achieve these goals, solution of the present utility model is:
The box firebreak device of a kind of thin plate rolling, be provided with cuboid casing, casing upper plate has been threaded case lid, case lid there is the observation window of transparent sealing, in casing, middle and upper part is fixed with vertical rectangular clapboard, the box height that the following distance to casing lower plate of described dividing plate is less than 1/2nd, its excess-three limit of dividing plate and cabinet wall seamless link, casing upper right side is connected with oil inlet pipe, the mouth of pipe of oil inlet pipe is fixed with screen pack, casing left upper end is connected with flowline, the mouth of pipe of flowline is fixed with screen pack, casing lower end is connected with blow-off pipe, blow-off pipe is provided with valve.
Preferably, described case lid is two, is installed on respectively on the casing upper plate of dividing plate both sides.
Box firebreak device described in the utility model, by the observation panel of case lid, can see backflow rolling oil condition in case in time.Casing is divided into left and right two Room by casing internal partition, can weaken the flowing amplitude of sump oil in fuel tank, and as far as possible by metallic oil tank to ground discharge; If the intensity of a fire arrives in the right side casing of fire prevention gate by pipeline, fire by remaining air burning totally, naturally extinguishes, thus reaches fire prevention object in right ventricle.The screen pack of casing oil-in can cushion oily Flow Velocity, filters broken paper tinsel bits.By sewage draining exit or case lid, can go out and regularly discharge sump oil and impurity, change screen pack.The utility model is convenient to arrange and operation, effectively reduces disaster hidden-trouble, stops fire spreading.
Accompanying drawing explanation
Fig. 1 is the structural representation of box firebreak device described in embodiment 1;
Fig. 2 is the structural representation of box firebreak device described in embodiment 2.
Detailed description of the invention
embodiment 1
As shown in Figure 1, the box firebreak device of a kind of thin plate rolling, comprise cuboid casing 1, in casing 1, middle and upper part is fixed with vertical rectangular clapboard 4, the following distance to casing 1 lower plate of dividing plate 4 is less than the casing 1 of 1/2nd highly, its excess-three limit of dividing plate 4 and the seamless link of casing 1 inwall, and casing 1 is divided into left and right two Room by dividing plate 4, the flowing amplitude of sump oil in casing 1 can be weakened, and as far as possible by metal cabinet 1 pair of ground discharge.The left and right two Room upper plates of casing 1 have respectively been threaded a case lid 2, case lid 2 have the observation window 3 of transparent sealing, can see backflow rolling oil condition in case in time.In order to reduce the air content in casing 1 as far as possible, the oil inlet pipe 5 on the right side of casing 1 is arranged in upper end, and the mouth of pipe of oil inlet pipe 5 is fixed with screen pack 6, and screen pack 6 not only can cushion oily Flow Velocity, and can filter broken paper tinsel bits.Casing 1 left upper end is connected with flowline 7, and the setting of flowline 7 can be parallel with oil inlet pipe 5, also can be vertical, and the height of flowline 7 also can a little less than oil inlet pipe 5, and the mouth of pipe of flowline 7 is fixed with screen pack 6.Casing 1 lower end is connected with blow-off pipe 8, blow-off pipe 8 is provided with sewage draining valve 9, sewage draining valve 9 is in closed condition usually, can regularly open sewage draining valve 9, discharge sump oil by blow-off pipe 8, larger impurity and replacing screen pack 6 can be cleared up by case lid 2 simultaneously.
On thin plate rolling production line, ROLLING OIL enters in casing 1 through oil inlet pipe 5, by screen pack 6 except the middle large granular impurity that deoils, then flows into the circulatory system through flowline 7.Once as there is the reason breaking out of fires such as broken belt suddenly in the operation of rolling, the intensity of a fire arrives casing 1 right ventricle by oil inlet pipe 5, and by air burning remaining in right ventricle totally, owing to being all liquid bottom casing 1, flare extinguishes naturally, thus reaches fire prevention object.
embodiment 2
Further to be on the safe side, as shown in Figure 2, on the basis of thin plate rolling with box firebreak device described in embodiment 1, oil inlet pipe 5 is installed oil inlet valve 10, flowline 7 is installed fuel-displaced valve 11.Now, the height of flowline 7 is arranged on casing 1 left side central portion and top.
In thin plate rolling production process, first case lid 2 and oil inlet valve 10 is opened, fuel-displaced valve 11 and sewage draining valve 9 are closed condition, and ROLLING OIL enters in casing 1 through oil inlet pipe 5, when ROLLING OIL capacity arrives case lid 2, screw case lid 2, open fuel-displaced valve 11, the flow velocity adjusting oil pipe 7 is less than the flow velocity of oil-in 5, as far as possible air in emptying casing 1, then adjust fuel tap door 11, make the flow velocity of flowline 7 identical with the flow velocity of oil-in 5.Once as there is the reason breaking out of fires such as broken belt suddenly in the operation of rolling, the intensity of a fire arrives casing 1 right ventricle by oil inlet pipe 5, and owing to being substantially all liquid in casing 1, air content is few, and flare extinguishes naturally, thus reaches fire prevention object.
