Abstract
The utility model provides a vacuum device. The vacuum device comprises a vacuum pipeline, wherein a thermal insulating layer is attached to surround the vacuum pipeline, a suction device is connected to the center of the thermal insulating layer by virtue of an air pipe, the air pipe is fixed on the vacuum pipeline by using a bolt, the thermal insulating layer comprises a lime layer which is covered with a nylon layer, the nylon layer is covered with a fixed layer, the fixed layer is formed by winding a hemp rope closely, the lime layer is thicker than the fixed layer, and the fixed layer is thicker than the nylon layer. The vacuum device has the advantages that the temperature rise rate of the pipeline is increased, the thermal insulation effect of the pipeline is improved, the production cost of an enterprise is reduced, and meanwhile, the ductility of plastics is improved.
Description
Technical field
The utility model relates to plastics-production device, is specifically related to a kind of vacuum system.
Background technique
Plastics are take synthetic resin or copal as basic material, add various plastic additives, reinforcing material and filler, under uniform temperature and pressure, the solid material of the type of making or crosslinking curing moulding is moulded in processing, the extensibility of plastics be enterprise to plastics itself higher requirement, the ability of distortion when the ductility of plastics represents that plastics are rolled or stretch in one or more directions; It depends on that itself produces ability and the strain hardening effect of plastic deformation, and the temperature that suitably raises, can make the ductility of plastics further improve, and draws high than can be larger.
Application number is that 201110198646.1 Chinese patent discloses the patent of invention that name is called " a kind of Vacuumizing device for plastic pelleting ", it comprises the vacuum pump being connected with the barrel of screw extruder by vacuum lead, the waste liquid settling tank being connected with vacuum pump, and one end and the exhaust gas recycling tube road that waste liquid settling tank is connected, the other end is connected with vacuum lead, on this exhaust gas recycling tube road, be provided with pressure regulator valve; Its apparatus structure is comparatively complicated, has promoted the cost of production of enterprise, is unfavorable for minuscule-type-enterprise's long term growth.
Model utility content
The purpose of this utility model is to provide a kind of vacuum system, reduces the cost of production of enterprise, promotes the ductility of plastics simultaneously.
In order to realize above object, the utility model provides a kind of vacuum system, comprises vacuum pipe, and improvements of the present utility model are, the periphery of described vacuum pipe is pasted with a thermal-protective coating, and the central authorities of described thermal-protective coating are connected with a suction means by tracheae.
Further, described tracheae is secured by bolts on described vacuum pipe.
Further, described thermal-protective coating comprises a lkd layer, and described lkd layer is coated with a nylon layer outward.
Further, the outer fixed bed that is arranged with of described nylon layer, described fixed bed is that the compact arranged rope made of hemp is around forming.
Further, the thickness of described lkd layer is greater than the thickness of described fixed bed, and the thickness of described fixed bed is greater than the thickness of described nylon layer.
A kind of vacuum system that the utility model provides, by thermal-protective coating being set at vacuum pipe outward, can greatly reduce the time that vacuum pipe rises to specified temp, play good heat insulation effect, thereby reduce the cost of production of enterprise, by a suction means, air in thermal-protective coating is found time simultaneously, strengthened heat insulation effect, thereby promoted the ductility of plastics.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of a kind of vacuum system that Fig. 1 provides for the utility model.
Embodiment
A kind of vacuum system that the utility model provides, has reduced the cost of production of enterprise, has promoted the ductility of plastics simultaneously.
Below in conjunction with the accompanying drawing in the utility model, the technological scheme in the utility model is clearly and completely described, obviously, described is only the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belongs to the scope that the utility model is protected.
The structural representation of a kind of vacuum system providing for the utility model referring to Fig. 1.A kind of vacuum system that the utility model provides, comprise vacuum pipe 1, the periphery of described vacuum pipe 1 is pasted with a thermal-protective coating, the central authorities of described thermal-protective coating are connected with a suction means 5 by tracheae 6, described tracheae 6 is fixed on described vacuum pipe 1 by bolt 7, by described suction means, air in described thermal-protective coating is found time, make described thermal-protective coating form vacuum, thereby guarantee the insulating power of described thermal-protective coating, described thermal-protective coating comprises a lkd layer 2, the outer nylon layer 3 that is coated with of described lkd layer 2, the outer fixed bed 4 that is arranged with of described nylon layer 3, described fixed bed 4 is for the compact arranged rope made of hemp is around forming, the temperature that has guaranteed vacuum pipe can significantly not reduce, thereby affect the ductility of plastics-production, the thickness of described lkd layer 2 is greater than the thickness of described fixed bed 4, and the thickness of described fixed bed 4 is greater than the thickness of described nylon layer 3.
Known by above description, a kind of vacuum system that the utility model provides, by thermal-protective coating being set at vacuum pipe outward, can greatly reduce the time that vacuum pipe rises to specified temp, play good heat insulation effect, thereby reduce the cost of production of enterprise, by a suction means, air in thermal-protective coating is found time simultaneously, strengthen heat insulation effect, thereby promoted the ductility of plastics.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
