Description
Technical field
The present invention relates to a kind of seal arrangement, particularly a kind of seal arrangement of dynamic mixer.
Background technique
In mechanical industry, in order to obtain good operational effect, must between rotor and stator or fixed block, keep certain clearance, to avoid the generation of faults such as friction, wearing and tearing and collision therebetween, simultaneously, because the existence in gap, nature can cause the leakage phenomenon of inter-stage and axle head, this will reduce the working efficiency of machinery, and this does not allow to produce.Sealing is exactly to have under the prerequisite of appropriate gap between reservation rotor and stator or fixed block, the effective measures of avoiding inter-stage and axle head to leak, and can realize that the mechanical structure of this function just is called seal arrangement, or be sealing unit.According to the difference of sealing configuration, it is several that sealing can be divided into shaft sealing, packing seal, mechanical seal, oil seal, float ring seal, magnet fluid sealing etc.In the mixed cell of resin vacuum encapsulation equipment, also need such seal arrangement, especially in the dynamic mixer of embedding equipment.But in real work, because the dynamic mixer complex structure is had relatively high expectations, independent a kind of sealing unit can not reach the seal request of equipment fully, so need the synergy of multiple sealing, could well finish sealing function.The sealing unit of the online dynamic mixer of band filler resin only adopts a kind of in the tradition axle envelopes such as O RunddichtringO, oil sealing and packing seal in the existing resin vacuum encapsulation system between running shaft and axle sleeve, and poor sealing performance easily leaks.Also cause feed liquid to be bonded on the running shaft easily, cause running shaft to stop operating, the complete machine cisco unity malfunction.
Summary of the invention
The present invention provides a kind of seal arrangement of dynamic mixer for solving the technical problem that exists in the known technology, and this installs good seal performance, can be applicable to the super mixer of band filler resin in the resin vacuum encapsulation equipment, improves its working stability.
The technological scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of seal arrangement of dynamic mixer, comprise the running shaft that is arranged on described dynamic mixer and the O RunddichtringO between its axle sleeve, the sealing device also comprise the stirring parts that is arranged on described dynamic mixer and the packing seal ring between the described axle sleeve and fill with the oiliness sealing fluid by running shaft, the Seal cage that stirring parts and axle sleeve form, in described Seal cage, be provided with the mechanical seal of running shaft, described mechanical seal comprises and is sleeved on described running shaft outside, end face seals the standstill seal ring and the motion seal ring of contact mutually, described standstill seal ring and described axle sleeve are affixed, described motion seal ring is fixed on the supporting frame, support frame as described above is sleeved on the outside of described running shaft, is clamped with the spring that is sleeved on described running shaft outside between support frame as described above and the described stirring parts.
Described packing seal ring is to be made by the teflon that contains bronze.
Described standstill seal ring and motion seal ring are made by silicon carbide.
Described O RunddichtringO is made by oil resistant rubber.
Described standstill seal ring is affixed by retainer and described axle sleeve.
Advantage and good effect that the present invention has are: adopt three grades of sealing configurations being made up of shaft sealing, end face seal and mechanical seal, inject the oiliness sealing fluid in the Seal cage between end face seal and mechanical seal simultaneously, improved sealability, effectively prevented the mixed solution leakage, improved working life of running shaft, axle sleeve, reduce its wearing and tearing and materials consumption in high speed operation, improved the overall performance of dynamic mixer.

Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1; the seal arrangement of a kind of dynamic mixer of the present invention; comprise three grades of sealings that end face seal that mechanical seal that the shaft sealing, standstill seal ring 5 and the motion seal ring 6 that are formed by O RunddichtringO 2 form and packing seal ring 4 form is formed; be characterized in: axle sleeve 3 protections are in the outside of running shaft 1; between running shaft 1 and axle sleeve 3, be provided with Sealing; the sealing part is common O RunddichtringO 2, and its material is an oil resistant rubber.Downward along running shaft 1, the jointing place of running shaft 1, axle sleeve 3 and stirring parts 9 is provided with mechanical seal, and this mechanical seal comprises standstill seal ring 5 and the motion seal ring 6 that is sleeved on the running shaft 1; In order to reduce processing and manufacture cost, standstill seal ring 5 is fixed on the retainer 11, and retainer 11 is sleeved on the fixed outside of running shaft 1 on axle sleeve 3; Motion seal ring 6 is fixed on the supporting frame 10, supporting frame 10 is sleeved on the outside of running shaft 1, at supporting frame 10 and be fixed between the stirring parts 9 on the running shaft 1 and be clamped with spring 6, spring 6 be supported on motion seal ring 6 below, Spielpassung between supporting frame 10 and the running shaft 1 makes the sealing surface of standstill seal ring 5 and motion seal ring 6 fit tightly.The material of standstill seal ring 5 and motion seal ring 6 is all silicon carbide (SiC), its hardness between corundum and diamond, the mechanical strength height, wear-resisting property is good, is suitable as very much abrasive material and uses.Supporting frame 10, retainer 11 are made processing, low cost of manufacture by Ordinary Steel.Above-mentioned mechanical seal can thoroughly prevent the feed liquid leakage.Third level sealing belongs to end face seal, be in the junction point of axle sleeve 3 outer ends and stirring parts 9, its Sealing is a packing seal ring 4, and its material is the strong teflon (F4) that contains bronze of abrasive resistance, the wear-resistant degree that contains bronze teflon (F4) is strong, has good corrosion resistance.Simultaneously, inject the oiliness sealing fluid in the Seal cage 7 that between second level sealing (mechanical seal) and third level sealing (end face seal), forms by running shaft 1, stirring parts 9 and axle sleeve 3.
When under the driving of running shaft 1 in motor screw during high speed rotating, the motion seal ring 6 of O RunddichtringO 2, mechanical seal and stirring parts 9 are all along with running shaft 1 high speed rotating, and the standstill seal ring 5 of mechanical seal is connected with axle sleeve 3, is fixed.
The shaft sealing of O RunddichtringO 2 is promptly used in first order sealing, can reduce the friction of running shaft 1 and axle sleeve 3, prevents that simultaneously foreign material such as air from entering the cavity of mixer; The mechanical seal that second level sealing promptly uses standstill seal ring 5 and motion seal ring 6 to form can thoroughly prevent the feed liquid leakage; The end face seal of packing seal ring 4 is promptly used in third level sealing, can prevent effectively that the resin feed liquid from entering Seal cage 7, prevents the feed liquid leakage.Both played the immersion of prevention resin material and the lubrication between increase standstill seal ring 5 and the motion seal ring 6 at the oiliness sealing fluid that the Seal cage between second level sealing (mechanical seal) and the third level sealing (end face seal) 7 injects, thereby can when safeguarding, can accurately judge the degree of wear of sealing unit again at every turn by the pollution situation of observing sealing fluid.
Although in conjunction with the accompanying drawings the preferred embodiments of the present invention are described above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away under the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within protection scope of the present invention.
