Abstract
The utility model relates to a pouring hybrid mechanical seal device of polyurethane equipment, which mainly solves the problem of too high friction temperature of an existing pouring hybrid mechanical seal device of the polyurethane equipment. The pouring hybrid mechanical seal device of the polyurethane equipment is characterized in that moving seal rings are arranged on the outer periphery of a stirring shaft; static seal rings which form conical moving seal fit with the moving seal rings are fixed in an inner cavity of a rack. Because the moving seal rings and the static seal rings of the pouring hybrid mechanical seal device of the polyurethane equipment are respectively made of flexible and hard materials, the friction temperature is lowered greatly; seal elements are easy to manufacture; the materials are easy to purchase; the realization effect of the seal device is improved effectively.
Description
Technical field
The utility model relates to sealing device, is specifically related to a kind of polyurethane plant and pours into a mould hybrid mechanically-sealing apparatus.
Background technology
Polyurethane plant is poured into a mould hybrid cast head and is used for being uniformly mixed material, by injecting batching and carry out mix and blend by shaft in head, thereby reach mixed uniformly effect, in order to prevent that batching leakage in head from affecting the service life of head part and the waste of material, adopts sealing, because the sealing place friction temperature of existing head is higher in head, need to move into cooling fluid cooling sealing device, in use, cumbersome, thus affect manufacturing schedule and the wasting of resources.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of polyurethane plant to pour into a mould hybrid mechanically-sealing apparatus, mainly solve existing polyurethane plant and poured into a mould the too high problem of hybrid mechanically-sealing apparatus place friction temperature, this polyurethane plant is poured into a mould hybrid mechanically-sealing apparatus good seal performance, and without cooling fluid, than being easier to realize sealing, thereby simplified original complicated sealing device, well reduced polyurethane plant and poured into a mould hybrid mechanically-sealing apparatus place friction temperature.
The technical scheme that the utility model adopts is: a kind of polyurethane plant is poured into a mould hybrid mechanically-sealing apparatus, comprise frame, power source, shaft, stirring-head overcoat and sprue gate, described power source provides shaft rotational power, described stirring-head overcoat is positioned at the end of frame, described stirring-head overcoat inside is provided with cavity volume, described shaft is positioned at frame stirring-head inner and its end and is positioned at described cavity volume, described sprue gate communicates with described cavity volume, it is characterized in that: the outside of described shaft is fixed with rotary packing ring, the inner side of described frame is fixed with described rotary packing ring and forms the stationary seal ring being sealed and matched, the sealing surface that contacts between described rotary packing ring and stationary seal ring is taper surface, described rotary packing ring adopts soft materials material, described stationary seal ring adopts rigid material material, described rotary packing ring is the one in tin bronze or aluminium bronze, described stationary seal ring is iron and steel material quality, frame inner side is fixed with sealing shroud, and described sealing shroud upper end is fixed with support, and institute's rotary packing ring is fixed on below described shaft boss, and slides axially along shaft.
The beneficial effects of the utility model are: the structure of pouring into a mould hybrid mechanically-sealing apparatus and adopt cone seal due to this polyurethane plant, sealing device adopts respectively soft materials and the sealing of rigid material, this hermetically-sealed construction not only has good airproof performance, and sealing device place produces heat while greatly reducing the operation of this equipment, without cooling, and then simplified whole sealing device, make equipment efficient operation smoothly.
Accompanying drawing explanation
Fig. 1 is explosion views of the present utility model.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the structure enlarged drawing at A place in the utility model Fig. 1.
Figure comprises 1, frame; 2, shaft; 3, stirring-head overcoat; 4, sprue gate; 5, sealing shroud; 6, stirring-head overcoat; 7, stirring-head; 8, elastic component; 9, rotary packing ring; 10, stationary seal ring.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
If Fig. 1 is in conjunction with Fig. 2, shown in Fig. 3, a kind of polyurethane plant is poured into a mould hybrid mechanically-sealing apparatus, comprise frame 1, power source, shaft 2, stirring-head overcoat 3 and sprue gate 4, described power source provides shaft 2 rotational powers, described stirring-head overcoat 6 is positioned at the end of frame 1, described stirring-head overcoat inside is provided with cavity volume, described shaft 2 is positioned at frame 1 stirring-head 7 inner and its end and is positioned at described cavity volume, described sprue gate 4 communicates with described cavity volume, the outside of described shaft 2 is fixed with rotary packing ring 9, the inner side of described frame 1 is fixed with described rotary packing ring 9 and forms the stationary seal ring 10 being sealed and matched, the sealing surface that contacts between described rotary packing ring 9 and stationary seal ring 10 is taper surface, described rotary packing ring 9 adopts soft materials material, described stationary seal ring 10 adopts rigid material material, described rotary packing ring 9 is the one in tin bronze or aluminium bronze, described stationary seal ring 10 is iron and steel material quality, frame 1 inner side is fixed with sealing shroud 5, and described sealing shroud 5 upper ends are fixed with support, and institute's rotary packing ring 9 is fixed on below described shaft 2 boss, and slides axially along shaft 2.According to such scheme, because the hybrid secret seal apparatus of polyurethane plant cast adopts the structure of cone seal, soft or hard is in conjunction with material device, and sealing is good, and sealing structure have friction, temperature low, without beneficial effects such as cooling fluids.
In the utility model, between described shaft 2 and rotary packing ring 9, being provided with elastic component rotary packing ring 9 is stirred axle 2 boss places and firmly blocks master, stationary seal ring 10 is frame 1 inner sides that are fixed on stirring-head overcoat 3 inner chamber upper ends, described stationary seal ring 10 is to be exerted pressure and fixed by sealing shroud 5 by support, effect by shaft 2 boss is pressed in rotary packing ring 9 tops on stationary seal ring 10 and realizes and being sealed and matched, the surperficial taper laminating of rotary packing ring 9 and stationary seal ring 10, shaft 2 provides power to realize the object of rotating by power source, power source is generator etc., shaft 2 rotates rotary packing ring 9 and realizes sound cone seal with stationary seal ring 10.
Described rotary packing ring 9 and stationary seal ring 10 are implemented cone seal device, rotary packing ring 9 adopts the soft material of aluminium bronze or tin bronze class to make, stationary seal ring 10 adopts hard material to make, rotary packing ring 9 and stationary seal ring 10 are made simple and convenient, soft or hard combination seal can reduce fricative heat, thereby without cooling fluid.
Every technical staff's notice: although the utility model describes according to the above-mentioned specific embodiment; but invention thought of the present utility model is not limited in this utility model; the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
