Description
Technical field
The present invention relates to a kind of direct sealed steel drum in the casing steel barrel field, this steel drum adopts barrel top cover as sealing surface, directly contact with cooperage spigot, and under the rubber cradle effect, forming direct closed type embedded flange sealer steel drum, the present invention also provides a kind of encapsulating method and fixing means of direct sealed steel drum.
Background technology
216.5 rising (China is decided to be 208 liters) closed steel drum is most popular in the world at present casing steel barrel, they all use G2 (non-tight gas thread size code) obturator as liquid injection port (also being discharge side), with the G3/4 obturator as ventilation mouth, China steel drum standard GB/T 325-2000, Europe steel drum standard EN 210:1999, international steel drum standard ISO 15750-2:2002 has made concrete norm to structure, size and the performance of closed steel drum.
Steel drum is mainly as the transportation storage vessel, vibrations, impact and accidental fall are common phenomena, also be to cause the sealer for steel drum main cause of seepage, especially the fire and the environmental pollution that cause of the sealer for steel drum seepage in the carriage of dangerous goods process is breakneck.Since the invention of steel drum embedded flange sealer, developed country is all carrying out antiseep research to sealer for steel drum.Since first double-deck packing ring in 1963, increase cross section sealing antiseep obturator patent disclosure after, the antiseep patent of invention of Chu Xianing improves constantly the sealer for steel drum leakage performance successively.Laid-open U.S. Patents specification sheets on the 30th US7.168.585B2 January in 2007 " preventing that the steel drum distortion from causing the obturator of seepage " patent of invention has certain representativeness, this invention is done barrel top cover boss hole flanging coning, make barrel top cover boss hole flanging and flange bung flange conial ring shape gap that the rubber cradle of certain altitude is set from top to bottom, around the anistree boss of barrel top cover, suppress an annular recess simultaneously, and a ring-type V-arrangement of punching press impression on the anistree boss step of barrel top cover specially should be located the steel drum strength reduction.The antiseep mechanism of this patent is: fall when steel drum is subjected to accidental shock, liquid in bucket is squeezed, the moment rising of liquid in bucket pressure makes barrel top cover produce gross distortion, at this moment the ring-type V-arrangement impression of strength reduction on the anistree step of annular groove around the barrel top cover boss and barrel top cover boss, under hydraulic shock power and barrel top cover distortion action of pulling stress, produce distortion at first, absorb a large amount of impact energys simultaneously, make that the V-arrangement impression exempts from distortion or makes barrel top boss hole flanging distortion very little with interior boss hole flanging and flange bung flange lock dress place on the anistree step of barrel top boss, even bucket top boss hole flanging produces certain distortion, because the cone rubber seal cavity has certain sealing height, the bottom rubber cradle is because the boss hole flanging distortion of bucket top loses compressive force, make rubber cradle loss part sealing function, and top, cone seal space rubber cradle is still under pressuring action, keep the better seal function, can effectively prevent seepage to a certain degree.
In sum:, on barrel top cover boss and flange sealer connection structure, still belong to a kind of indirect-type sealing, elastic clip stressed joint structure although traditional embedded flange sealer has the support of multinomial antiseep patented technology abroad.As shown in Figure 1, at first flange bung flange 16 will be fixed on the position of the anistree boss 5 of barrel top cover, and keeps good sealing state, and then clamps by gas thread with flange bung flange 16 and cooperage spigot 29 indirectly, under the sealing function of rubber cradle 38, finally reach steel drum leak free purpose.For attachment flange bung flange 16, will be at the anistree boss 5 of the surperficial punching press of barrel top cover 1, form a cylindrical hole flanging of anistree boss, then the flange bung flange 16 that puts rubber cradle 42 is put into the hole flanging of anistree boss 5, the anistree flange 18 of flange bung flange 16 is embedded in the boss interior anistree 14 of the anistree boss 5 in bucket top, the anistree flange surface 19 of flange bung flange 16 is as axial location, straight tube 21 curls into turnup limit 43 to the outside under lock dress mould squeezing action, and the hole flanging of the anistree boss 5 in parcel bucket top compresses downwards, push up anistree boss bottom surface 13 under the location of anistree flange surface 19 up to bucket, make the height of barrel top boss 5 produce elastic deformation, when holding out against turnup limit 43, the extruding of lock dress just in time stops.The anistree boss 5 in bucket top is in the anistree flange surface 19 of flange bung flange 16 and the elastic clip locking structure state on turnup limit 43, flange bung flange 16 be fixed on simultaneously barrel top cover 1 above, rubber cradle 42 utilizes elastic deformation to clamp-on in the gap that arc 12 and anistree flange surface 19, flange bung flange outer wall 20 form in an anistree boss bottom surface, bucket top 13, the anistree boss when lock dress extruding clamps, form the hermetic barrier band one, prevent liquid in bucket from small contact surface gap 41 outside bucket seepage.Though it is very big that flange bung flange 16 and cooperage spigot 29 adopt gas threads to clamp the intensity that is rigidly connected, but because cooperage spigot 29 belongs to indirect sealing with barrel top cover 1, the screw thread of cooperage spigot 29 and flange bung flange 16 intensity that is rigidly connected is big again, the seepage that can not stop barrel top cover 1 distortion to cause.Because anistree boss 5 structural strengths in bucket top are limited, flange bung flange 16 pushes up the destruction that anistree boss 5 adopts elastic clip stressed joint structures can not resist barrel top cover 1 deformation force with bucket, there are practical problemss such as technical risk is big, poor reliability in the stability that keeps indirect closed type flange sealer.
As shown in Figure 2, when being subjected to accidental shock in transportation and handling procedure, the sealer for steel drum of the indirect closed type elastic clip of tradition stressed joint structure falls, liquid in bucket is squeezed, hydraulic shock pressure makes barrel top cover 1 produce bulging deformation, barrel top cover bottom surface 15, the interior arc 12 of anise 14 and anistree boss bottom surface 13 and anistree boss is started rapidly by the distortional stress of barrel top cover 1 in the boss, the contact surface that breaks away from flange bung flange 16, because the original height in anistree boss 5 distortion backs, bucket top is lowered, bucket anistree boss 5 in top and anistree flange surface 19, elastic top locking structure state between the turnup limit 43 becomes loose configuration state, rubber cradle 42 loses the pressuring action of arc 12 in anistree boss bottom surface 13 and the anistree boss immediately, compression and back elastic force disappears, can not stop up the contact surface gap 41 between anistree boss 5 in bucket top and the flange bung flange 16, liquid in bucket leaks into outside the bucket from the contact surface gap 41 that bucket pushes up anistree boss 5 and flange bung flange 16 under pressure.Cooperage spigot 29 and flange bung flange 16 are owing to adopt gas thread rigidity clamped joint, sealing property is not subjected to the deformation effect of barrel top cover 1, can not produce seepage, but the anistree flange 18 of flange bung flange 16 loses the positioning action of anise 14 in barrel top boss, want to open cooperage spigot 29 this moment and take out raw materials, flange bung flange 16 can be because of losing the radial location effect, and the dismounting torque of following cooperage spigot 29 produces and rotates, make cooperage spigot 29 dismounting difficulties, this situation is restricted steel drum when repairing and repeated usage.
Steel drum the invention initial stage mainly as the oil industry packing of product, the inner cleaning of steel drum is simple relatively when reclaiming repeated usage, and steel drum is used for chemical frbre industry in a large number now, coating, food, industries such as agricultural chemicals, the interior cleanliness level of bucket requires very high when reclaiming repeated usage, since traditional steel drum G3/4 ventilation mouth sectional area have only G2 inlet sectional area 1/5th less than, in adopting modern high-pressure injection technology washing bucket during residue, a large amount of cleaning liquids have little time to discharge outside the bucket in finite time, cleaning efficiency can't be improved, cleanliness level is also undesirable in the bucket, in checking bucket, need during cleanliness level the workman with the naked eye spy on barrel by the G2 inlet in the cleaning situation, because the G3/4 ventilation mouth is very little, assist illuminator insertion and transposition are spied on very inconvenient, and naked eyes are very easily tired, therefore checking efficiency is low, poor reliability.
Summary of the invention

Fig. 6: be direct sealed steel drum embedded flange sealer, the part sectional view of type conical bench cooperage spigot 29, because the sealing surface boss limit 7 of taper combination concave station bung flange 26 is conical, its back cut diameter is greater than lower port diameter, the seal cavity volume of whole taper combination concave station bung flange 26 increases, standard specification rubber cradle 38 increases the back at seal cavity and compresses not tight, in order to make 26 sealings of taper combination concave station bung flange more reliable, the present invention changes the neck 36 of traditional cooperage spigot 29 into the type conical bench shape by right cylindrical, the diameter of step neck 34 is 57.0～58.0 millimeters, than 56.0 millimeters big 1.0～2.0 millimeters of the diameters of traditional straight cylinder neck 36, the step neck 34 that diameter is big adopts transition to be connected by the little straight cylinder neck 36 of conical neck 35 and diameter.
Fig. 7: be direct sealed steel drum embedded flange sealer part sectional view under normal condition, because barrel top cover 1 pushes up taper combination concave station bung flange that anistree boss 5 and boss limit 7 form 26 by bucket flange bung flange 16 is isolated in steel drum inside, when type conical bench cooperage spigot 29 is installed rubber cradle 38 screw-in bucket inside flange bung flanges 16, the extendible portion boss limit 7 of barrel top cover 1 directly contacts with rubber cradle 38 as sealing contact surface, when the wedge angle 31 that is tightened onto cooperage spigot lid limit 30 when type conical bench cooperage spigot 29 and taper are made up concave station arc face 27 and are contacted, cooperage spigot 29 is subjected to positioning action to be stopped to descend, the extendible portion boss limit 7 of barrel top cover 1 forms screw thread rigidity clamped joint structures with type conical bench cooperage spigot 29 under the effect that screws of the negative thread 24 of the outside thread 37 of type conical bench cooperage spigot 29 and flange bung flange 16, the compression and back elastic force that rubber cradle 38 utilizes the compressing of type conical bench cooperage spigot 29 to produce covers bottom surface, limit 32 at cooperage spigot, lid limit arc 33, step neck 34, straight tube chamfering 23, form rubber elastomer hermetic barrier band together in the taper circular groove space 39 that forms between the extendible portion boss limit 7 of barrel top cover 1 and the taper combination concave station arc face 27, be enough to stop liquid in bucket seepage outside bucket.
Fig. 8: be that direct sealed steel drum embedded flange sealer suffers part sectional view under the deformation state, because directly the barrel top cover 1 of closed type flange sealer and flange bung flange 16 form to rivet in lock dress back and are rigidly connected, the extendible portion boss limit 7 and the type conical bench cooperage spigot 29 of barrel top cover 1 forms the screw thread clamping again and is rigidly connected when screwing, make direct closed type flange sealer possess good shock resistance, fall deformability.
When steel drum is subjected to accidental fall in transportation or loading and unloading, liquid in bucket is squeezed and forms the fluid pressure impact, the flat thin wall construction rigidity of barrel top cover 1 is the poorest, produce distortion at first, the outwards serious projection of barrel top cover, the tensile stress that barrel top cover 1 distortion produces makes the boss interior anistree 14 of the anistree boss 5 in bucket top, arc 12 starts rapidly in anistree boss bottom surface 13 and the anistree boss, the anistree flange 18 and the anistree flange surface 19 that break away from flange bung flange 16, make the anistree flange 18 of flange bung flange 16 lose positioning action, anistree flange surface 19 loses pressuring action simultaneously, there is not rubber ring seal because directly closed type flange sealer bucket pushes up between the contact surface of anistree boss 5 and flange bung flange 16, so even anistree flange surface 19 loses thrust, liquid in bucket also can't leak into outside the bucket by the contact surface gap 41 that bucket pushes up between anistree boss 5 and the flange bung flange 16.After boss outer anistree 2 that the tensile stress of barrel top cover 1 starts the anistree boss 5 in bucket top and anistree boss surface 3, run into the cylindrical boss outer wall 6 that vertical bucket pushes up anistree boss 5, because the cylindrical geometries non-deformability of outer wall of boss 6 is fine, and the very big flange bung flange 16 of liner intensity, add that barrel top cover boss limit 7 overall construction intensity under the screw thread rigidity clamping action of type conical bench cooperage spigot 29 is very big, the distortion tensile stress of barrel top cover 1 runs into outer wall of boss 6, can only change stress direction along cylindrical outer wall, disappear towards diffusion on every side.
When impact is fallen when acting directly on the direct sealed steel drum embedded flange sealer of barrel top cover surface, because the extendible portion boss limit 7 of barrel top cover is by the screw thread rigidity clamping action of type conical bench cooperage spigot 29, firmly be fixed in the taper combination concave station bung flange 26, local strength is very big, directly the closed type flange sealer can not produce distortion, it can pass to barrel top cover to impulsive force, it making barrel top cover 1, anistree boss outer anistree 2, and 3 generations of anistree boss surface are out of shape but this distortion is identical with above-mentioned condition, can not influence the sealing property of direct closed type flange sealer.When there is difference of pressure in circular groove space 39, part liquid can be under the effect of bucket internal pressure, tolerance clearance 40 along the outside thread 37 of the negative thread 24 of flange bung flange 16 and type conical bench cooperage spigot 29 arrives circular groove spaces 39, because circular groove space 39 is fixed spaces, the hermetic barrier band that rubber cradle 38 forms under the compression of type conical bench cooperage spigot 29 is enough to stop fluid seepage generally speaking, when the moment rising of liquid in bucket pressure, caulking gum packing ring 38 can move towards force direction under the fluid pressure effect, contact pressure on the sealing surface is risen rapidly, and greater than liquid in bucket pressure, liquid in bucket can't leak into outside the bucket by direct closed type flange sealer seal ring.
Fig. 9: be the overview of direct sealed steel drum under normal condition, 2 direct closed type embedded flange sealers of G2 are arranged on its barrel top cover 1, they promptly are that inlet is again a ventilation mouth, can exchange functions of use arbitrarily, when direct sealed steel drum at splendid attire coating, paint, agricultural chemicals etc. easily precipitate in the liquid product use, has unique function, it inserts a mixer in a G2 inlet 47, accretion is stirred at the bottom of making barrel, make, lower floor's liquid produces convection current, reach the uniform requirement of concentration rapidly, directly liquid is extracted out and used and in another G2 inlet 47, insert aspirating pump or flush coater, will liquid product extract out and not re-use after stirring.After using, direct sealed steel drum is collected into repairing, during renovation bucket factory, because barrel top cover 1 has 2 G2 inlets 47, when steel drum turns over turnback, the bucket top down, when entering the high-pressure injection cleaning product line, because 2 G2 inlet 47 diameters are identical, the high-pressure injection head can successively enter 47 pairs of steel drum inside of G2 inlet and carry out the cleaning of highly pressurised liquid impact peel, when a high-pressure injection head enters 47 work of G2 inlet, another G2 inlet 47 is as discharge side, a large amount of cleaning liquids are in time discharged, make barrel top cover bottom surface 15, ladle body inwall 44, residue on the bucket bottom inside face 46 is in time cleaned, otherwise cleaning liquid accumulates in the bucket, make barrel top cover 15 surfaces can't hydro-peening clean, because G2 inlet 47 deflection ladle body inwalls 44, if only at G2 inlet 47 hydro-peenings, can produce inner walls of steel drums cleans inhomogeneous, this moment, injector head withdrawed from after having cleaned a side inner walls of steel drums, the another injector head enters opposite G2 inlet 47, inner walls of steel drums is carried out spraywashing once more, and the G2 inlet 47 that withdraws from injector head is discharged a large amount of cleaning liquids again as discharge side, the steel drum of this 2 G2 inlets 47 is high efficiency when cleaning, and cleanliness level is good.Raffinate checks that when the steel drum cleaning inside was spent, because G2 inlet 47 diameters are big, light entered with naked eyes visual very convenient in the workman extracts bucket out, is difficult for producing kopiopia, makes steel drum cleaning inside degree checking efficiency height, good reliability.
