Description
Technical field
The present invention relates to a kind of row's urea plants, and in particular to is blow molded row's urea plant of urea box, belongs to Oiltank structure
Component technology field.
Background technique
With the exhaust emission standard of various countries implementation and deeply, more and more urea box assemblies are widely applied to the country
The SCR(selective catalytic reduction system operating of outer large size depot) on, product is suitable for truck, the fields such as tractor etc., bus.
Important composition component one of of the urea plant as urea box is arranged, urea box bottom is generally positioned at, for must
Urea liquid is vented when wanting.Blow molding process reaches its maturity at present, and more and more manufacturers' selections pass through blow molding work
Skill realizes urea box molding.Blow molding process maximum advantage compared with Shooting Technique is that blow molding process can realize urea box one
Secondary molding avoids the upper-lower casing Welding Problems of the molding existing urea box of Shooting Technique.But blow molding process and injection molding
Technique is compared there is also certain disadvantage, since wall thickness will be consistent everywhere for the urea box of blow molding process limitation blow molding,
And it is difficult as Shooting Technique to put urea plug in the screw-type that urea box bottom straight forming goes out to be similar to drinking bottle mouth
Structure.Therefore it is directed to blow molding process urea box, designing a kind of row's urea plant is then more particularly important.
Summary of the invention
The present invention exactly for the technical problems in the prior art, provides a kind of urination white, quiet clothes for being blow molded urea box
It sets, the technical solution whole design is ingenious, compact-sized simple, which had not only been able to satisfy the anti-urea function of urea box, but also can be straight
It connects and utilizes on the molding urea box of blow molding process, it is practical.
To achieve the goals above, technical scheme is as follows, a kind of row's urea plant being blow molded urea box, special
Sign is that row's urea plant includes by welding pedestal, fixed plug, two sealing rings and fixing screws, and the fixed plug is logical
Fixing screws setting is crossed on welding pedestal, described two sealing rings be respectively assembled at fixed plug sealed groove after again with welding
Base plate through holes D interference fit realizes sealing function.
As an improvement of the present invention, the welding pedestal packet is made of welding base body and embedded nut,
It is formed using encapsulated technique is molded.Welding base body material is HDPE(high density polyethylene (HDPE)), it is necessary to and urea box body material
Matter could unanimously be directly welded at urea box bottom by hot plate welding welding procedure.Embedded nut material is stainless steel or warp
Metallic substrates processing is crossed to meet corrosion resistant carbon steel.Internal screw thread size can be M5, M6 or M8 etc..Bottom structure is set
It is calculated as hexagon flange surface structure, plays the role of positioning rotation stop in embedded injection molding.
As an improvement of the present invention, setting there are two triangle hole slot and is gone in ring recessed on the welding base body
Slot and small recesses, the triangle hole slot in order to guarantee weld base body uniform wall thickness, be conducive to Shooting Technique form.
It is outer to be conducive to Shooting Technique molding in addition to that can guarantee uniform wall thickness for annular groove.The purpose of this slot is designed simultaneously also with grabbing
It connects device and grabs and connect.Before it will weld pedestal 1 and the welding of urea box bottom using hot plate welding process, grasper claw distinguishes snap ring row
In two grooves of groove and small recesses or so, firm promptly function is realized.Thickness must be greater than 3mm at H, prevent
Wall thickness is excessively thin herein as caused by manufacturing tolerance, and urea is caused to leak out from there.
As an improvement of the present invention, the highstrenghtpistons such as described fixed plug selection POM either HDPE pass through injection molding
Technique is fabricated.Therefore wall thickness problem is paid attention in the fixed plug of design, according to Shooting Technique wall thickness control in 2.5mm-
Between 4mm.It prevents from leading to Forming Quality problem since wall thickness height difference is excessive.It is fixed to design two inner groovies beyond the Great Wall for filling
With sealing ring to play sealing effect, through-hole is for installing fixing screws, and handle arrangement is arranged in the fixation beyond the Great Wall, for putting
Operation is simple in urea process.
As an improvement of the present invention, the sealing ring material is EPDM or HNBR, finally according to surrounding medium and
At original selection.The size selection of sealing ring will be according to the diameter D1 of through-hole diameter D and fixed plug inner groovy on welding pedestal 1
And slot high h is codetermined.Of course for save the cost, can also be gone according to the size of the existing ○-shaped seal ring of existing market
Define D, D1 and h value.
A kind of welding method of row's urea plant of blow molding urea box, which is characterized in that the assemble welding technique is as follows:
Step 1: the through-hole that a diameter is D2, this through-hole D2=D+6mm. are formed in urea box bottom by punch device
And guarantee that this through-hole, 6mm are welding procedure tolerance；
Step 2: pedestal 1 will be welded by hot plate welding process and be welded on urea box bottom, welding surplus is 3mm, and is protected
Card welding base plate through holes and the through-hole of urea box bottom are coaxial, and position degree controls within welding deviation；
Step 3: two sealing rings are respectively assembled at fixed plug sealed groove；
Step 4: fixed plug being screwed into the through-hole of welding pedestal, and guarantees assembly in place, guarantees fixed plug and weldering
It connects pedestal firmly to fit together, sealing ring and welding base plate through holes interference fit realize sealing function at this time.
Step 5: screw is screwed into the embedded nut on welding pedestal, and is revolved using tool according to regulation torque
Conjunction is tightened, and entire row's urea plant installation process has been finally completed, when that need to realize urination element function, it is only necessary to utilize tool
Screw is screwed out, and fixes plug with finger manipulation, is screwed out, urea can pass through through-hole outflow in welding pedestal.
Compared with the existing technology, the invention has the advantages that, urea box row's urea plant which proposes is
The very useful device designed for the molding urea box of blow molding process, ingenious in design, operation is simple, and further
It ensure that the quality of product, reduce enterprise's production cost.
