Description
Technical field:
The utility model belongs to the application of industrial chemicals manufacture field follower device.This plays a role in the middle of installing therein the element rotation, can be mainly used in plastic material such as plastics in the middle of viscous state processing.
Background technology:
Mixing (mixing) device of rheids such as plastic melt is varied, and plastics professional journals and books have introduction more always.Melting efficiency is high in these devices, " handing over row sound gear ring mixing refining head " (being called for short the JC mixing refining head) that has " plastics " 1985 the 3rd phases (Beijing plastic institute is edited and publish, domestic distribution) 2-5 page or leaf published article (calling civilian first in the following text) to introduce.It is I from former West Germany " Kunststoffe " Vol.63, No.10 (1973), the kneading device development of 686-691 published article (calling Wen Yi in the following text) report.The effect of literary composition second kneading device is splendid according to newspaper.Germany H Bo Tante, published in 1986, through Liu Jinping translate, g has showed the kneading device identical with its architectural feature once more among Fig. 3 .2 in " extruding engineering design and the calculating " book (Sinopec publishing house in March, 1991 Beijing the 1st edition) in Chen Wenying school.But its mixing elements dynamic and static number of teeth on circumference is identical, unavoidably causes melt pressure vibration in the extruder in the extrusion in theory; Existing between the dynamic and static tooth layer does not have the space-time gap of shearing.And inconvenience is made and cleaned to this device; The sound tooth might take place in the running to be bumped mutually and stings.I study alone at civilian second kneading device, the innovative design success JC mixing refining head, eliminated the former and caused in the machine shortcomings such as melt pressure vibration, derived a mathematical conjecture again as the pervasive condition of design, write civilian first subsequently in person and deliver.
English periodical " plastics engineering " Vol.42, No.10, OCT1986 has contrasted the experimental result of 3 kinds of novel mixing elementses in the P39-41 published article (calling literary composition third in the following text), therefrom see C element (its root diameter is 6 inches) melting efficiency the highest (seeing 41 pages of Wen Bingdi).From literary composition third Figure2., the C element is similar to the gear ring of JC mixing refining head, and the literary composition third dated C element is to draw from United States Patent (USP) 1984 No. 4447156.Yet from the U.S.Paten May8 that duplicates, 1,984 4447156 full contents see that this patent is irrelevant substantially with the C element of Wen Bingzhong: the total form is different, as, between each tumbler of this patent is thread connection, does not have key connecting, and on the C element diagram rotor keyway is arranged; The dynamic and static element number of teeth of this patent is identical, and the C element illustrates the quiet number of teeth 8, the moving number of teeth 9.As seen the C element is not to draw from this United States Patent (USP).
The kneading device that does not still have JC mixing refining head pattern in the aforementioned works of Germany H Bo Tante.So far do not see domestic and international public publication as yet and appear the essentiality content that has developed disclosed JC mixing refining head technology.
After the literary composition first was delivered, I had carried out improving several times to the JC mixing refining head again.Wen Jiazhong has introduced the pervasive condition and the part-structure designing technique of design JC mixing refining head.The existing claimed content of this patent application is not disclose.Domestic before this a few family units employed JC mixing refining head material object all is by me, provides in the mode of transferring the possession of single product, and its transfer contract has all been stipulated the technical know-how clause.
The utility model content:
The utility model provides a kind of " handing over row sound gear ring rheid kneading device ", its objective is following four problems that solution only adopts this immediate prior art of the described JC mixing refining head of civilian first cann't be solved:
1. how to allow between the inside and outside circle cylinder of mixing section inner chamber this fluid passage, space beyond the sound tooth can guarantee rheid can be mixing when flow is enough big fully, even, it is little to reach the little and whole device volume of flow resistance again.
When the dynamic mixing device of the existing other types that disclose was attached on single screw extrusion machine machine barrel and the screw rod, mixing section inner chamber external cylindrical surface diameter all equaled the extruder barrel internal diameter.If convention like this, because concrete Machine Designs such as moving gear ring location and necessary assurance axle root torsional strength are to the restriction of accessory size, so for small-bore extruder, the mixing section intracavity space may be very narrow, all length of this point and minor diameter gear ring has also limited the number of teeth, these may make that rheid axial flow velocity in the limited axial length of mixing section of big flow is too high, the area that sheared by the sound between cog is very little and the time is very short, the number of times deficiency that materials flow is cut apart and sheared by transverse pulse, thereby cause mixing insufficient and adverse consequences that flow resistance is excessive, also greatly reduce the superiority that adopts the JC mixing refining head.
2. when the inside and outside circle cylinder diameter of mixing section inner chamber differs big, this inner chamber press close to inside and outside circle cylinder place, fluid because of the peripheral velocity that stands to shear and the area difference distance that stands to shear of whenever circling bigger, can cause whole mixing lack of uniformity; Moving tooth makes original width fan-like pattern tooth tooth root drag narrower than tooth top have decline to increase the danger of damaging again because of tooth depth increases.
3. along with quiet gear ring external diameter increases, not necessarily need the quiet gear ring axial width (cylindrical portions may) that and then increases that the ratio of its external diameter is diminished thereupon, load and unload quiet gear ring, especially the mixing section that is full of rheid from inner chamber takes out quiet gear ring one by one, firmly have improper just being stuck in to drag the easier appearance of motionless situation on the outer casing inner wall slightly, i.e. loading and unloading are difficulty further.
4. go into the equipment discharging opening external diameter of mixing section inner chamber greater than feed and require mixing section forward under the situation of discharging opening reduced diameter at mixing section inner chamber external cylindrical surface diameter, how to avoid existing in the whole kneading device runner harmful viscous flow dead angle.
The utility model has added following technical scheme on this immediate prior art basis of aforementioned JC mixing refining head:
1, the mixing section at dynamic and static gear ring (among Fig. 16,7) place, its inner chamber outside diameter is gone into the equipment discharging diameter of this kneading device greater than feed; 2, moving tooth profile of tooth makes tooth tooth root width greater than addendum width through geometric transformation; 3, the sensing of moving tooth and quiet tooth all is the oblique sensing that departs from axle (among Fig. 1 9) axis; 4, the mixing section two ends are connected to and expand stream ring (among Fig. 1 8) and contracted flow ring (among Fig. 1 2); 5, the axle front end has the circular cone heading tape round platform hex bolts head of pushing down moving gear ring (among Fig. 1 1); 6, be pasted with the split type ring set between whole quiet gear rings and the overcoat (among Fig. 1 3).
Adopt the 1st scheme can enlarge markedly the mixing section intracavity space, solve above-mentioned problem 1., but drawn above-mentioned deficiency 2., also given prominence to deficiency 3..After adopting the 2nd, 3 schemes again, reach and still keep invariable in the intercommunication area on the axle axis direction is relatively rotating between the sound gear ring, simultaneously can overcome above-mentioned deficiency 2., increase whole mixing uniformity, comprise relying on rheid that sound tooth interlayer sheared to make the latter be able to move, thereby promote that rheid radially mixes along its accompanying flank inclined-plane to the adhesion of adjacent quiet between cog and adjacent moving between cog rheid; Moving tooth has also increased dependability.Adopt the 4th, 5 schemes then can solve above-mentioned viscous flow dead angle problem 4..Adopted the utility model of above 5 schemes can be used in various bores and required to improve the single screw extrusion machine of productive rate, obtain whole mixing fully, effect of uniform, include to be beneficial to and carry out chemical reaction, as graft reaction of polymer or the like.Adopt the 6th scheme again, then can overcome above-mentioned deficiency 3.: the split type ring set of being made up of two semi-ring covers (among Fig. 1 4) or polylith makes the overcoat (action in opposite directions) or therefrom take out of whole gear rings and split type ring set can being packed into together, thereby makes the operation of loading and unloading gear ring in the production become much easier.
The benefit that adopts the 1st scheme is for example: φ 45 extruder front ends, and annular space thickness only 3 when mixing section inner chamber internal diameter (millimeter) 39, external diameter 45, and narrow being difficult to of space adopts.When external diameter increased to 65, girth increased to 1.44 times, the ratio S of big or small inner chamber annular cross section area
1/ S
0Reach 5.37 times; If big chamber number of teeth Jing Quan gets 16, moving-coil gets 15, Jing Quan remains 0.4S
1(referring to Fig. 3); Tentatively loculus number of teeth Jing Quan gets 10, moving-coil gets 9, and Jing Quan remains 0.63S
0, 0.4S
1/ 0.63S
0Still reach 3.4 times; Identical in big or small inner chamber sound gear ring number, be under 8 and 7, the rheid that passes in and out big or small inner chamber stand to cut apart the ratio of total number of share of stock be the ratio of the corresponding average number of teeth, promptly 15.5/9.5=1.63 doubly, total number of share of stock difference is 6 * 2
15, the pulse of any two adjacent teeth interlayer that whenever circles is simultaneously sheared (effect that the rheid of tooth interlayer is had the compression stretching of seemingly kneading dough repeatedly) number of times and is increased to 15 * 16=240, the difference of visible effects from 9 * 10.After having adopted the 3rd scheme again, about φ 2 slices sampling check of extruding with the flexible PVC powder formulation finds no breaks part easily, this with adopt the 3rd scheme before polyethylene add in the mixing extrudate of air and except that uniform fine and closely woven bubble, also exist isolated about φ 2 air pockets of only a few to compare, reflect that whole mixing uniformity is improved.
Industrial departments such as the chemical industry that adopts the 1st scheme and the 2nd, 3,4,6 scheme that the utility model is enlarged to be applied to except plastic processing, food, medicine, can adopt the mixing section inner chamber of big external diameter, it is good just can to make multiple rheid material formula not only pass through big flow but also melting effect in suitable axial length (highly).
Concrete usefulness of the present utility model can partly relatively obtain notion with rotary vane type static mixer (calling " revolving quiet " in the following text) group that accounts for same space roughly from it.Promptly, change 15.5 arranged side by side " revolving quiet " if can will go up example into along Zhou Pingjun 15.5 teeth, because the latter is cut apart materials flow and must be reversed the materials flow direction simultaneously in its each axial element length, and this can not finish in several millimeters the distance that is equivalent to the tooth layer thickness, so tentatively hypothesis can be provided with 8 element lengths of " revolving quiet " in the axial length of 15 layers of gear ring, so only from cutting apart total number of share of stock that whole materials flows get, the utility model just is 2 of " revolving quiet " group
15/ 2
8=128 times.And, roughly be limited to the cutting apart and mixes of " revolving quiet " group enter the mouth the materials flow enter respectively everywhere from it in, and the utility model makes whole materials flow whenever by all being disturbed behind one deck tooth.
