Abstract
The utility model relates to an axial sealing device for mixers. Both ends of each main shaft 1 of the mixer are respectively provided with a lining ring 2. The lining rings 2 are provided with two elastic sealing elements 4 and 15. The periphery of the sealing member is matched with a fixing seat 5. The fixing seat is fixed on the periphery of the sealing member by an end cover 12. A hollow cavity 6 is arranged between the lining rings, the fixing seats and two sealing members. The fixing seat is provided with an air inlet pipe 7. The upper end of the air inlet pipe 7 is communicated with a hollow press pump 16, and the lower end of the air inlet pipe 7 is communicated with a hollow cavity. The high-pressure air entering from the air inlet pipe causes the sealing members to deform, and then the clearance of the contact part of the lining rings and the end cover is blocked. The utility model effectively prevents axial material leakage, and improves the sealing performance of the utility model.
Description
The utility model is a kind of seal arrangement that is used for various dissimilar mixing machines, belongs to the mixing machine field of mechanical technique, can be used for the mixing machine of industries such as feed, grain and oil, chemical industry, building materials.
At present, the employed sealing configurations of processing industry mixing machine such as grain and oil feed all are seal ring, the form of sealing seat, parts such as its centre wall contact with the sealing seat rigidity, be subjected to the influence of processor's production technique height, sealability can not reach requirement fully, causes sealing part to the material that leaks outside, so the axial seal performance of mixing machine is an insoluble problem always.
The purpose of this utility model provides a kind of mixer axial seal arrangement, and it can prevent that mixer axial from leaking material, can improve the reliability of mixer axial sealing greatly.
The technical solution of the utility model is: a lining ring 2 is equipped with at the two end part at every main shaft of mixing machine 1 (mixing machine has single shaft, two kinds of models of twin shaft), lining ring closely is fixed together with Cock screw 3 and axle and rotates with axle, to the axle center elastomer seal I 4 and elastomer seal II 15 are housed successively from axle head on the lining ring, the two elastomer seals segment distance of being separated by is installed, and Sealing is made by elastic caoutchouc.The peripheral cooperation of Sealing is equipped with fixed base 5, forms the cavity 6 of a hollow between fixed base, lining ring and two Sealings.End cap 12 is fastened on the mixing machine wallboard 8 by bolt 10 and packing ring 9, fixed base 5 is fixed together with end cap 12 through bolt 14 and packing ring 13, and be fixed on the outside of elastomer seal 4,15 by end cap, suction tude 7 is housed on the fixed base 5, suction tude one end links with cavity 6 and communicates, and the other end and pneumatics pump 16 link.O RunddichtringO 11 is equipped with in end cap 12 and wallboard 8 connection places, when mixing machine is worked, the pneumatics pump is pressed into gas in the cavity by suction tude and is delivered on two elastomer seals, because elastomer seal rubber has deformability, produce distortion under the pressure of high-pressure air, the rubber after the distortion is close on the lining ring, and the slit, everywhere of lining ring and end cap contacting point is all sealed up, so just prevent effectively that the material in the trough from extruding (promptly axially leak and expect), improved sealability widely.
Because adopt said structure, this mixer axial seal arrangement has prevented axial leakage material effectively, improved the reliability of mixer axial sealing widely.
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model
Each position sequence number mark is as follows in the accompanying drawing: 1, main shaft; 2, lining ring; 3, Cock screw; 4, elastomer seal I; 5, fixed base; 6, cavity; 7, suction tude; 8, wallboard; 9, packing ring; 10, bolt; 11, O RunddichtringO; 12, end cap; 13, packing ring; 14, bolt; 15, elastic seal ring II; 16, pneumatics pump.
, to the axle center elastomer seal I 4 and elastomer seal II 15, the two elastomer seals segment distance of being separated by is housed successively from axle head on the lining ring and installs with Cock screw 3 affixed lining rings 2 at the two end part of mixing machine main shaft 1, Sealing is made by elastic caoutchouc.4,15 peripheral cooperations of Sealing are equipped with fixed base 5, form the cavity 6 of a hollow between fixed base 5, lining ring 2 and two Sealings 4,15.End cap 12 is fastened on the mixing machine wallboard 8 by bolt 10 and packing ring 9.Fixed base 5 links with end cap 12 through bolt 14 and packing ring 13, and is fixed on the outside of elastomer seal I II 4,15 by end cap.Suction tude 7 is housed on the fixed base 5, and suction tude one end links with cavity 6 and communicates, and the other end and pneumatics pump 16 link, and O RunddichtringO 11 is equipped with in end cap 12 and wallboard 8 connection places.
