Model utility content
The purpose of this utility model is to provide the good vacuum pumping device of a kind of vacuumizing effect.
For achieving the above object, the utility model adopts following technological scheme:
The utility model cryogenic insulated cylinder vacuum pumping device, comprise pumped vacuum systems and gas cylinder internal heating system, pumped vacuum systems comprises vacuum pump unit, first gas collecting tube and cryogenic insulated cylinder, vacuum pump unit is connected by flexible pipe with the first gas collecting tube, first gas collecting tube is connected with cryogenic insulated cylinder pipeline, gas cylinder internal heating system comprises high pressure positive blower, Electric furnace, second gas collecting tube and air intake arm, the air outlet of high pressure positive blower is connected with the suction port of Electric furnace, the air outlet of Electric furnace is connected with the second gas collecting tube by flexible pipe, the suction port of air intake arm is connected with the second gas collecting tube, the air outlet of air intake arm stretches in cryogenic insulated cylinder.
The utility model cryogenic insulated cylinder vacuum pumping device difference from prior art is: air first to be sent in Electric furnace by high pressure positive blower and heated by the utility model, the gas of heating enters in cryogenic insulated cylinder by the second gas collecting tube, utilize high-temperature gas to be heated by gas cylinder internal, recycling vacuum pump unit carries out vacuumizing process.Because under high temperature, (100 DEG C ~ 130 DEG C) air density diminishes, molecular thermalmotion aggravates, and moisture and organic molecule are more easily desorbed at this temperature, and therefore, vacuum pumping rate and effect improve all greatly.
The utility model cryogenic insulated cylinder vacuum pumping device, also comprise temperature transducer, temperature transducer is arranged on Electric furnace.
Temperature transducer can be monitored in real time from Electric furnace gas temperature out, guarantees that temperature range is between 100 DEG C ~ 130 DEG C.
The utility model cryogenic insulated cylinder vacuum pumping device, also comprise vacuum valve, vacuum valve is arranged on cryogenic insulated cylinder.
By controlling vacuum valve opening-closing size, the speed vacuumized accurately can be controlled.
The utility model cryogenic insulated cylinder vacuum pumping device, also comprises filter, and filter is arranged on the suction port of high pressure positive blower.
Filter is convenient to remove the impurity in air, avoids introducing impurity and causing gas cylinder contaminated.
The utility model cryogenic insulated cylinder vacuum pumping device, the cryogenic insulated cylinder quantity that the first gas collecting tube is connected by flexible pipe is identical with the cryogenic insulated cylinder quantity that the second gas collecting tube is connected by air intake arm, is 2-8.
Multiple cryogenic insulated cylinder is vacuumized simultaneously, greatly improve and vacuumize efficiency.
The utility model cryogenic insulated cylinder vacuum pumping device, also comprises heating and thermal insulation stove, and heating and thermal insulation stove inside and outside wall interlayer is provided with 80 ~ 100mm asbestos thermal insulation layer, inwall is provided with electric heating tube, electric heating tube is also installed in bottom, and heating and thermal insulation stove can avoid the loss of heat, and energy-saving effect is remarkable.
Because cryogenic insulated cylinder internal compartment is multilayer insulant and aluminium foil, even if gas cylinder internal is by after gas-heated, the temperature difference in the space between gas cylinder interlayer and gas cylinder outer wall still exists, at this moment, the cryogenic insulated cylinder of sealing can be put in heating and thermal insulation stove and heat, so that the temperature in space reaches unanimity in gas cylinder internal, gas cylinder interlayer and gas cylinder outer wall, control at 100 DEG C ~ 130 DEG C, vacuumizing effect can be better.
In sum, the beneficial effects of the utility model are, vacuum pumping rate is fast, effective.
Below in conjunction with accompanying drawing, a kind of cryogenic insulated cylinder vacuum pumping device of the present utility model is described further.
Accompanying drawing explanation
