Abstract
The utility model discloses a vacuum air extracting device comprising a vacuum box and a vacuumizer connected with the vacuum box through a pipeline. The vacuum box is hinged with a box gate and elastic sealing glue is stuck on the periphery of the box gate; meanwhile, the bottom of the vacuum box is provided with a guide rail and a container filled with a semi-finished product can smoothly enter into and exit from the vacuum box through the guide rail; and the vacuum box is further provided with an air release valve. According to the vacuum air extracting device, air bubbles of the semi-finished product can be rapidly pumped out through low-voltage vacuum and the efficiency is improved; and meanwhile, the vacuum air extracting device is provided with an anti-colliding layer, so that the service life is long.
Description
Technical field
The utility model belongs to chemical machinery field, relates in particular to the equipment that utilizes low-voltage vacuum to bleed.
Background technology
Along with the extensive use of continuous development of social life and new material, the fiberglass industry size also obtains fast development.In order to give glass fiber reinforced plastics product surface aesthetic, ageing-resistant, anti-contamination, corrosion-resistant, need coat the one layer of polymeric face coat to it, from but glass fiber reinforced plastics product obtains more property.When producing this polymer, through inevitably having bubble in the thick semi-finished product after stirring, can be if do not get rid of this bubble to having a negative impact in the subsequent handling.The method for exhausting that adopts at present all is with the semi-finished product hold over night, bubble is discharged naturally, thereby efficient is lower, can not drain fully bubbling fully.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides a kind of vacuum suction device that utilizes low-voltage vacuum to bleed.
Technical scheme: for solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of vacuum suction device; Comprise vacuum tank, with the evacuator that said vacuum tank pipeline is connected, said vacuum tank is hinged with chamber door, posts elastic sealant around this chamber door; Simultaneously said vacuum tank bottom is equipped with guide rail, and this guide rail makes and half-finished container is housed can passes in and out vacuum tank smoothly; Said vacuum tank also is provided with air bleeding valve.
Half-finished container will be housed advance vacuum tank along guide rail; Fasten chamber door; Start evacuator, when treating that the vacuum tank internal gas pressure is reduced to 0.05 ~ 0.1MPa and keep bleeding in 1 ~ 4 hour, close down evacuator then; And open air bleeding valve and make the vacuum tank inner and outer air pressure consistent, open chamber door at last and pull out half-finished container is housed.
As preferably; The inwall of said vacuum tank and chamber door all is covered with corrosion-resistant coating, and said corrosion-resistant coating material is polypropylene or polytetrafluoroethylene (PTFE), because the polymer semi-finished product have certain corrosivity to metal; Be coated with and play a protective role after corrosion-resistant coating is housed, prolong the service life of equipment
As preferably, the outer wall of said vacuum tank also is provided with reinforcement, thereby improves the intensity of equipment.
Beneficial effect: compared with prior art, the utlity model has following advantage: fast the semi-finished product bubble is extracted out through low-voltage vacuum, improved efficient; Corrosion-resistant coating is arranged simultaneously, long service life.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
Shown in accompanying drawing 1, a kind of vacuum suction device comprises vacuum tank 1 and the evacuator 2 that is connected with said vacuum tank 1 pipeline, on this vacuum tank 1, is hinged with chamber door 3, around this chamber door 3, posts elastic sealant 4.Said in addition vacuum tank 1 inwall scribbles the erosion shield of polypropylene material; Be equipped with guide rail 5 in the bottom of vacuum tank 1 thereby the turnover of semi-finished product container conveniently is housed; Certainly on vacuum tank 1, also be hinged with chamber door 3; Thereby around this chamber door 3, post elastic sealant 4 improve tightnesses guarantee air tight, so thereby open chamber door 3 easily in the air pressure unanimity that also is provided with on the said vacuum tank 1 inside and outside air bleeding valve 6 usefulness the casees.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
