Description
Technical field
The utility model relates to vacuum pumping device technical field, is specifically related to a kind of unpowered vacuum pumping device.
Background technique
Existing vacuum pumping device is generally adopt vacuum pump to vacuumize, but adopts the mode of vacuum pump evacuation, and one is because the operation of vacuum pump can produce noise, easily causes noise pollution, and two is that vacuum pump needs motivational drive, consumes the energy.
Summary of the invention
For the problems referred to above, it is simple, reasonable in design that the purpose of this utility model is to provide a kind of structure, and work noise free, without the need to consuming the unpowered vacuum pumping device of energy source and power.
Realize the technical solution of the utility model as follows:
Unpowered vacuum pumping device, for vacuumizing seal container, comprise the gas holder be communicated with seal container by the first pipeline and the sluicing pond be in below gas holder, the bottom of gas holder is communicated with the liquid line extended in sluicing pond below liquid level, in sluicing pond bottom liquid level and gas holder between distance be greater than 9.8mm, described first pipeline communication has liquid inlet pipe, liquid inlet pipe is provided with the second control valve controlling liquid medium circulation in liquid inlet pipe, the first pipeline between liquid inlet pipe and seal container is provided with the first control valve controlling medium circulation in seal container, described liquid line is provided with the 3rd control valve controlling medium circulation in liquid line.
Have employed technique scheme, in use, gas holder is communicated with needing the seal container vacuumized by the first pipeline, close the first control valve, 3rd control valve, and open the second control valve, environmental liquids medium is made to enter gas holder by liquid inlet pipe and after being full of whole device, close the second control valve, open the first control valve again, 3rd control valve, because the distance between bottom liquid level in sluicing pond and gas holder is greater than 9.8mm, in system, total pressure is greater than 9.8m water column, under extraneous atmospheric action, in system, water-column can decline, and the partial air in seal container can by the first pipeline transfer gas holder, until mineralization pressure state of equilibrium, then the first control valve is turned off immediately, 3rd control valve, reopen the second control valve and fill liquid in gas holder, then the second control valve is turned off, repeat to open the first control valve, 3rd control valve, and so forth, until close to being in vacuum state in seal container, this device cardinal principle relies on control valve the seal container needing to vacuumize and this apparatus system to be combined, by the difference of Help of System internal pressure and external atmosphere pressure, form natural power, utilize liquid to discharge the gas in seal container, utilize the mobility of gas, gas in dilution seal container, ceaselessly repeats dilution until be infinitely close to vacuum state in container.The utility model structure is simple, reasonable in design, with low cost, work noise free, without the need to consuming energy source and power, reduction equipment internal air pressure can be reached, to reduce in seal container want the object of separation of material boiling point.
Further, for the ease of the discharge of gas in seal container and gas holder, the top of described first pipeline communication seal container and gas holder.
Further, the first pipeline between described liquid inlet pipe and gas holder is communicated with outlet pipe, this outlet pipe is provided with the 4th control valve and outlet valve.By operating the 4th control valve, ducted gas can be discharged by outlet valve, avoids gas to produce interference in vacuum.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the theory diagram of control system in the utility model;
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As Fig. 1, unpowered vacuum pumping device, for vacuumizing seal container 1, comprise the gas holder 3 be communicated with seal container by the first pipeline 2 and the sluicing pond 4 be in below gas holder, the bottom of gas holder is communicated with the liquid line 5 extended in sluicing pond below liquid level, liquid line is in being arranged vertically, in sluicing pond bottom liquid level and gas holder between distance be greater than 9.8mm, first pipeline communication has liquid inlet pipe 6, liquid inlet pipe is provided with the second control valve 7 controlling liquid medium circulation in liquid inlet pipe, the first pipeline between liquid inlet pipe and seal container is provided with the first control valve 8 controlling medium circulation in seal container, liquid line is provided with the 3rd control valve 9 controlling medium circulation in liquid line.In concrete enforcement, the top of the first pipeline communication seal container and gas holder.The first pipeline between liquid inlet pipe and gas holder is communicated with outlet pipe 10, and this outlet pipe is provided with the 4th control valve 11 and outlet valve 12.Gas holder is communicated with outlet valve 13 in order to discharge the gas in gas holder; Bypass line 14 is communicated with in side, sluicing pond, the upper end of this bypass tube is communicated with the upper end portion in sluicing pond, it is in the liquid level highest order of liquid medium in sluicing pond, a liquid-discharging tube 15 is communicated with in the lower end in sluicing pond, liquid-discharging tube 15 is provided with a liquid discharging valve 16, the lower end of bypass tube is communicated with the exhaust end of liquid discharging valve, remains that the liquid medium in sluicing pond is in certain height like this, and unnecessary liquid medium discharges sluicing pond from liquid-discharging tube.In a particular application, and non-required produces separately gas holder and sluicing pond, it can adopt has tank body in the liquid medium heating system of tank body as the gas holder in the utility model, as cryogenic liquide medium enters in tank body through liquid inlet pipe 6, and be able to rising by the heating arrangement temperature of tank body and be discharged in sluicing pond, in order to heat supply, so greatly reduce the cost of production of this vacuum pumping device, only need to adopt several pipelines and several control valve to realize.
See Fig. 2, in concrete enforcement, first control valve, second control valve, 3rd control valve, 4th control valve is solenoid valve, vacuum pumping device also comprises for automatically controlling vacuum pumping device control system that this is unpowered, this control system comprises the vacuum sensor for detecting degree of vacuum in seal container, and control the first control valve, second control valve, 3rd control valve, the controller of the 4th control valve alternation, the vacuum degree detected in seal container is passed to programmable controller by vacuum transducer, controller compares according to the value of setting and the vacuum degree of seal container, controller then controls the first control valve according to the result compared, second control valve, 3rd control valve, the work of the 4th control valve, namely when the degree of vacuum detected when degree of vacuum reaches controller setting value, controller just can control four control valve Close Alls, and send prompting by being connected alarm unit with controller, just vacuum state is in seal container, realize full-automatic vacuum-pumping process like this.
