Description
Technical field
The utility model relates to technical field of vacuum, is specially a kind of vacuum pumping device.
Background technique
Vacuum refers to the given space of the gas lower than atmospheric pressure, and namely in every cubic centimetre of space, gas molecula number is approximately less than the given space of 2,005.Vacuum is relative to barometric pressure, and non-space does not have material.With the minimum pressure that modern air-exhaust method obtains, still have hundreds of molecules in the space of every cubic centimetre and exist.Gas rarefied content is a kind of objective measurement to vacuum, and the most direct physical measurements is the gas molecula number in per unit volume.Density of gas molecules is less, and gas pressure is lower, and vacuum is higher.Vacuum technique sets up the physical environment lower than atmospheric pressure, and carry out the required technology such as technique making, physical measurement and scientific experimentation in the environment.Rubbish in train upper toilet is difficult to discharge, and is adopt current scour at present, both wasted precious water resources, and washed away again unclean.Existing a kind of vacuum pumping device, adopts vacuum technique, can solve the problem.
Model utility content
The purpose of this utility model is to provide a kind of vacuum pumping device, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme: a kind of vacuum pumping device, comprises device body, suction tude and mixed flow tube; The left side of described device body offers suction port, right side opening is provided with exhaust port and upper-end surface offers material feeding mouth; Described suction tude is arranged on device body inside, and left end communicates with suction port; The left end of described mixed flow tube is connected with suction tude right-hand member, and left side communicates with exhaust port.
Further, described suction tude is positioned at below material feeding mouth.
Further, the right mouth of pipe of described suction tude is taper mouth structure.
Compared with prior art, the beneficial effects of the utility model are: this vacuum pumping device unitary design, are convenient to install and maintenance; Take pressurized air as power, clean hygiene, saves again a large amount of precious freshwater resources; Advanced technology, novel in design; Structure is simple, with low cost, of many uses, is easy to promote.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Reference character: 1. device body; 2. suction tude; 3. mixed flow tube; 11. suction ports; 12. exhaust ports; 13. material feeding mouths.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of technological scheme: a kind of vacuum pumping device, comprises device body 1, suction tude 2 and mixed flow tube 3; The left side of described device body offers suction port 11, right side opening is provided with exhaust port 12 and upper-end surface offers material feeding mouth 13; It is inner that described suction tude 2 is arranged on device body 1, and left end communicates with suction port 11; The left end of described mixed flow tube 3 is connected with suction tude 2 right-hand member, and left side communicates with exhaust port 12.
Further, described suction tude 2 is positioned at below material feeding mouth 13.
Further, the right mouth of pipe of described suction tude 2 is taper mouth structure.
Of the present utility model when designing: during use, material, in material feeding mouth 13 inletting device body 1, falls into the surrounding of suction tude 2 with in mixed flow tube 3; Pressurized air, by suction port 11 inletting device body 1, flows into mixed flow tube 3 by suction tude 2, discharges from exhaust port 12; When pressurized air is by mixed flow tube 3, produce negative pressure in suction tude 2 surrounding and mixed flow tube 3 inside, and material feeding mouth belongs to open design, therefore, it is possible to produce high speed and high pressure air-flow in suction tude 2 surrounding; This high speed and high pressure air-flow drives material to enter in mixed flow tube 3, provides power, discharge from exhaust port 12 by pressurized air.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
Claims (3)
