Abstract
The utility model discloses a vacuuming device for a glass insulation liner. The vacuuming device comprises a bracket, wherein a rectangular frame is mounted at the upper end of the bracket; supporting rings are arranged at intervals between opposite support plates of the rectangular frame; natural gas pipes corresponding to the supporting rings in a one-to-one manner are arranged below the bracket; a fire nozzle is arranged at the upper end of each natural gas pipe; a front baffle and a rear baffle are arranged on the front side bracket and the rear side bracket of the rectangular frame respectively; a supporting plate is mounted on the front end surface of the front baffle; a vacuuming pipe connected with an exterior vacuum pump is arranged on the supporting plate; vacuuming branch pipes correspond to positions of the back-up rings in a one-to-one manner are arranged on the vacuuming pipe. The vacuuming device is ingenious in design, ensures that the insulation liner is kept vertical and stable in the vacuuming process, improves processing quality, and improves the vacuum degree of the glass liner, so that the insulation effect is improved essentially; when the liner opening part of the insulation opening is heated, the length of the flame is appropriate, the uniformity of the temperature is good, and white extraction cannot occurs at a silver layer at the bottom of the bottle, so that the scrap rate is reduced.
Description
technical field:
The utility model relates to glass vacuum flask processing, relates in particular to a kind of glass vacuum flask vacuum pumping device.
background technique:
Glass vacuum flask is double-deck mechanism, and silver nitrate solution is injected into glass liner interlayer by tail pipe, and silver layer is plated in interlayer both sides (being inner bag skin and outer courage internal layer), after having plated silver, moisture content is discharged from tail pipe, glass liner interlayer contains moisture, moisture must be dried, and after glass liner vacuumizes, could be incubated.
Glass vacuum flask is mainly that insulation degree will be got well, and key is must vacuum in interlayer, and more vacuum refill insulation degree is better, and vacuumizing is exactly that Yao pumps air in interlayer.When vacuumizing, bottle inner bag oral area will add flare and heats, and flare can not be oversize, and temperature can not be too high, otherwise, easily silver layer at the bottom of bottle is taken out to white generation waste product.
There is defect in the design of the vacuum pumping device of glass refills all the time, causes the fixing poor stability in position when vacuumizing, and the quality of impact processing, makes vacuumizing effect bad, causes glass liner of thermos insulation degree not high;
In addition, tradition adopts the low coal gas of calorific value to heat, and in bottle, a heating-up temperature does not reach demand, and at the bottom of easily causing bottle, silver layer is taken out whitely, cannot use.
model utility content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of glass vacuum flask vacuum pumping device, structural design is novel, can easily and fast glass vacuum flask be fixed, good stability, in heating process, in bottle, temperature is high, and at the bottom of being difficult for causing bottle, silver layer is taken out whitely, and the heat insulation effect of glass liner of thermos is improved.
The technical solution of the utility model is as follows:
Glass vacuum flask vacuum pumping device, comprise support, it is characterized in that: the upper end of described support is provided with rectangle frame, between the relative support plate of rectangle frame, be fixed with filler ring spaced apart, described support below is provided with and filler ring natural gas tube one to one, natural gas tube vertically stretches out along filler ring center, the external air feed tank of natural gas tube, natural gas tube upper end is provided with flame tap, the end of flame tap is provided with asbestos guard, the hinged front screen that is provided with on the support of described rectangle frame front side, the support of rectangle frame rear side is provided with vertical backboard, on front screen front-end face, supporting plate is installed, supporting plate is provided with the vacuum-pumping tube of external vacuum pump, vacuum-pumping tube is provided with filler ring position and vacuumizes one to one arm.
Described glass vacuum flask vacuum pumping device, is characterized in that: the slewing area of described backboard turns to vertical position by horizontal position, and the spacing parting bead of glass liner of thermos that is positioned at each filler ring both sides is also installed on backboard.
Described glass vacuum flask vacuum pumping device, it is characterized in that: described vacuumize arm by be connected in turn upper rubber pipe on vacuum-pumping tube, glass bend pipe, in rubber pipe, glass straight tube, lower rubber pipe, glass conical tube, the cone end of glass conical tube is down.
Described glass vacuum flask vacuum pumping device, is characterized in that: described vacuum pump is positioned at the back side of front screen, is also provided with diffusion pump on the connecting tube between vacuum pump and vacuum-pumping tube.
The utility model has the advantages that:
1, the utility model structural design is novel, by the structures such as the spacing parting bead of glass liner of thermos on filler ring, front screen, backboard and backboard, can guarantee the vertical stability of glass liner of thermos in the process vacuumizing, and improves quality of processing;
2, the utility model increases a diffusion pump between vacuum pump and vacuum-pumping tube, under the rough vacuum condition causing at preevacuation pump, silicone oil in heat pump, make the explosive evaporation of being heated, generate steam, gap with flank speed by the spouts at different levels of this pump sprays, the gas molecule of glass liner interlayer inside is diffused into and in steam, is brought to the position that preevacuation pump can act on, by preevacuation pump, extracted out rapidly, make system reach the requirement of high vacuum, the glass liner of production is than high 6 ~ 10 ℃ without diffusion pump insulation degree;
3, the utility model increases asbestos guard at the front end of flame tap (flame projector), can be so that when the bottle inner bag oral area to glass liner of thermos be heated, flare moderate length, temperature homogeneity is good, bottle the end silver layer there will not be take out white, thereby reduced reject rate.
4, the design that vacuumizes arm of the present utility model can conveniently regulate flexibly in course of working, thereby carries out the vacuum pumping of glass liner of thermos, improves work efficiency.
