Technical field
The utility model relates to the small size single stage rotary-vane vaccum pump that a kind of household vaccum packer is used, especially a kind of small size single stage rotary-vane vaccum pump with gas-liquid separation reflux device.
Background technique
According to the standard code of JB/T5971-1992 Machinery Ministry, present domestic rotary-vane vaccum pump series is divided by how much speed of exhausts, is divided into 10m
3/ h, 16m
3/ h, 20m
3/ h, 25m
3/ h, 40m
3/ h, 63m
3/ h, 100m
3/ h, 160m
3/ h, 250m
3/ h9 kind does not have the speed of exhaust at 10m
3Below/the h, be fit to the small size single stage rotary-vane vaccum pump that household vaccum packer uses; In addition, be radially assembling between the present above-mentioned vacuum pump series, its fuel tank and the pump housing and be connected, volume is big; What its relief opening was adorned all is simple gas-liquid separation filter of being made by filter cotton.Its gas-liquid separation is filtered not thorough, row. and gas port often has mist of oil and oil droplet ejection; And its working life is also short, needs often to change.Therefore these vacuum pumps exist fuel consumption big, waste energy; The fuel tank volume is big, is not suitable for the supporting use of household small-size vacuum package machine; And befouling environment, influence drawbacks such as the workman is healthy.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and provides a kind of speed of exhaust at 10m
3Below/the h, dwindle vacuum pump volume, energy-saving and cost-reducing small size single stage rotary-vane vaccum pump.
The technological scheme that the utility model technical solution problem is adopted is: a kind of small size single stage rotary-vane vaccum pump, comprise motor, the pump housing and fuel tank, in the described pump housing, be provided with rotor, turnover oilhole and suction valve, the rotating shaft of rotor is provided with blade, described fuel tank comprises exhaust port and goes out oil inlet hole, described motor, the pump housing and fuel tank set gradually vertically, and described turnover oilhole goes out oil inlet hole and is communicated with in the axial direction with described.
Described exhaust port is provided with a gas-liquid separation reflux device,
Described suction valve is an one-way control valve.
Described fuel tank comprises the fuel tank body, is provided with radiating fin on the surface of described fuel tank body.
Compared with prior art, the utlity model has following beneficial effect: the utility model has been filled up in China's vacuum pump product standard series the speed of exhaust at 10m
3The specification that/h is following; Have that compact structure, volume are little, the remarkable advantage of fuel-economizing, material-saving, energy-saving and cost-reducing and protection environment, and created condition for China's vacuum package machine realization product miniaturization, family oriented.

Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
As shown in Figure 1, the utility model small size single stage rotary-vane vaccum pump comprises motor 1, pump housing part 2, fuel tank part 3 and gas-liquid separation reflux device 34.
Pump housing part 2: comprise that the surface is shaped on radiating fin, a side-lower axially is shaped on the pump housing 21 of a turnover oilhole, is loaded on the suction valve 22 on the pump housing 21 and is loaded on the interior rotor of the pump housing.
Rotor: comprise rotor body 23, be distributed on the blade 24 in rotor body 23 peripheral groove and be loaded on the rotating shaft 25 at its center.Described rotating shaft 25, near eccentric whole rotor body 23 side suction valve in the pump housing that supports is driven by described motor 1, drives whole rotor body 23 rotations, and then drives blade 24 rotations; Described blade 24, its surface coverage has one deck oil film, in the rotary course, its end face all the time with pump housing suction valve near a side inwall keeping sealing state reliably, thereby a side forms vacuum area near making pump housing inner chamber suction valve, realizes container is vacuumized.
Fuel tank part 3: comprise that the surface is shaped on the fuel tank body 31 of radiating fin, be contained in fuel tank body 31 bottoms one end, be used to discharge the purge cock 32 of fuel tank body inner fluid; Be contained in fuel tank body 31 axial ends, be used to observe the oily window 33 of oil level in the fuel tank body 31; Be loaded on fuel tank body 31 tops, be used for the gas-liquid separation reflux device 34 that gas-liquid separation filter to be filtered, fluid reclaims, exhaust is used.The fuel tank body 31 axial the other ends are connected with the pump housing 21, and by the pump housing 21 the above turnover oilhole 27, fluid can enter the described pump housing 21 inner chambers in fuel tank body 31, and cladding seals on described blade 24.Described fuel tank body 31 axially is connected with the pump housing 21, compact structure, and volume is little, and this is that the utility model is different from one of notable feature of any other vacuum pump.
Gas-liquid separation reflux device 34, it is assembled from the inside to the outside successively in proper order by mandrel 34-2, the mistake filter ruffle 34-3, shielding can 34-4, filtration adsorption layer 34-5 and the case 34-6 that are installed on the base 34-1, between filter ruffle 34-3 and the shielding can 34-4 cover plate 34-7 is being housed excessively, as shown in Figure 3.It can carry out pump housing part formed gas-liquid in to container vacuumizing and exhausting process fully effectively to separate, and institute's separated liquid oil can be back in the fuel tank body again, make in the gas of discharge and do not have mist of oil, fluid and steam, fuel-economizing, free from environmental pollution, this is two of the utility model notable feature of being different from other any vacuum pump.
