Embodiment
As shown in Figure 1, miniature power pumped vacuum systems of the present utility model (or being vacuum pumping device or miniature power vacuum pumping device) comprises housing 1, housing 1 comprises interconnective roof, diapire and sidewall, on roof, have power water inlet 2, on diapire, have power water out 4, on sidewall, have pumped gas entrance 3.The water spray projector system 5 of housing 1 inside is connected with power water inlet 2, and the below that is positioned at water spray projector system 5 in housing 1 is provided with mixing chamber 6, and pumped gas entrance 3 is also positioned at the below of water spray projector system 5 in the vertical direction.Power water out 4 is communicated with mixing chamber 6, and pumped gas entrance 3 is communicated with mixing chamber 6, and water spray projector system 5 is provided with multiple water orifices, and the plurality of water orifice is communicated with mixing chamber 6.Multiple water orifices refer to more than two, and quantity is best at 20-1000.
Water spray projector system 5 for the power water that receives power water inlet 2 and flow into and by this power water from (direction of the mixing chamber 6) ejection downwards of its water orifice.
Below the working procedure of native system is described:
Taking the fetus forming process in tire manufacturing process process as example, in fetus forming process, to use assembly drum, in steam injection assembly drum, make it expand to form fetus, then the steam in assembly drum with the mode vacuumizing discharge cause assembly drum shrink, then remove fetus, then carry out the production of next product.In this process, need to have pumped vacuum systems to complete and vacuumize operation, and this device can replace existing pumped vacuum systems.This device is directly power consumption not, only needs the power water of 0.05-0.1Mpa, and the existing water source that the power water of this condition can form from tyre production technology process obtains.Power water is flowed into this device by pipeline from power water inlet 2, water spray projector system 5 goes out to form jet by the power water receiving from its multiple water orifice Jet with downward flow directions, the pressure of power water is become to kinetic energy, needing the gas of the process system of axle vacuum to be forced to bring into jet by jet from pumped gas entrance 3 mixes mixing chamber 6 is interior, the air-water mixture forming is discharged from power water out 4, so repeatedly works and has just reached the object of axle vacuum.The pressure of power water is 0.05-0.1Mpa, can reach-0.01-0.09Mpa of degree of vacuum.
If there is no qualified existing water source, the devices such as the water pump that need to be so only 2-3KW with power consumption produce this power water.Power consumption is little, highly beneficial to energy-conserving and environment-protective.
More stable in order to make to vacuumize, degree of vacuum is lower, reach better vacuumizing effect, as shown in the dotted arrow in Fig. 1, multiple jets of multiple water orifice ejections of water spray projector system 5 intersect at a bit upper, and this point of intersection is positioned on pumped gas entrance 3 place horizontal planes.
Further, in order to reach better vacuumizing effect, multiple water orifices of water spray projector system 5 are positioned in same level, and are uniformly distributed around same central point is circular.
Further in order to reach better vacuumizing effect, the speed of the jet of multiple water orifice ejections of water spray projector system 5 is 7-20 rice per second again.
Water spray projector system 5 can be orifice plate, can as long as can spray the device of jet.Water spray projector system 5 can be also that spiral mazy type is accelerated centrifugal device.
For the shape and structure of mixing chamber 6, can further be optimized to taper, the point of intersection of multiple jets of multiple water orifice ejections of water spray projector system 5 is positioned on the center line of this taper mixing chamber 6, as shown in fig. 1, the sectional area of the mixing chamber 6 of taper shrinks gradually to power water out 4 directions.That is to say, if mixing chamber 6 is cone shapes, the diameter of the mixing chamber 6 of cone shape dwindles gradually to power water out 4 directions.
As shown in Figure 2, replace mixing chamber 6 to make vacuumizing effect better with Lavalle tubular type mixing chamber 7, Lavalle tubular type mixing chamber 7 adopts the structure of convergent-divergent channel, and its cross-section area first shrinks further expansion.For the quantity of pumped gas entrance 3, also can be set to two relative gas accesses, or arrange three, four or more.
The above only, to preferred embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.Every in the claim limited range of model utility, any amendment of making, be equal to replacement, improvement etc., all should be within protection domain of the present utility model.
