By the pipe 16 that is equipped with transmitting device 17, soft expansion jack 12 is connected on the pressure fluid memory device 15.
According to the present invention, pressure fluid can be an incompressible fluid, promptly as the liquid of water or oil, and perhaps compressible fluid air for example.
At it is incompressible fluid for example under water or the oil condition, and device 17 is used for the fluids in the memory device 15 are transferred to soft inflatable jack 12 through managing 16, and device 17 is made up of for example suitable pump.When pressure fluid was formed by pressurized air, described transmitting device 17 was corresponding with pressurized air lines, and pressurized air lines has all known suitable parts (valve, switch etc.).
Pressure fluid is preferably incompressible fluid for example oil or water.Preferably in soft inflatable jack 12, provide the cushion rubber that is filled with coercible gas (for example air) then.Such cushion rubber plays the effect of energy disperser, and it can make flow rate of fluid steadily also limit or even eliminate the delay time that viscous product 2 flow to the discharge orifice 90 of emptying vessel 60.
Use the advantage of soft inflatable jack 12 to be embodied in economy and ease especially.And inflatable jack 12 adds any extra obstacle for emptying vessel 60.Therefore be easy to the imagination and use dual system that it also can be operated in wait time, this will significantly improve capacity rating.
Another advantage that is provided by the variation embodiment of Fig. 2 is can be easily and the such equipment of assembly and disassembly apace.
Yet according to one of Fig. 2 equipment optional useful feature, the lid 13 or even emptying vessel 60 safety valve that is used to discharge overpressure air is equipped with.
With the method identical with Fig. 1 equipment, the equipment of Fig. 2 for example is to be arranged in the upstream that is used to pack viscous product 2 (for example being packaged in the device of (cartridges) in the tube).
The operation of the emptying equipment of Fig. 2 is very simple.Soft jack 12 makes its expansion by means of transmitting device 17, and it is relevant with emptying viscous product 2 needed pressure in flexible container 30.
Fig. 3 illustrates another embodiment according to emptying external member of the present invention.This external member comprises the flexible container 21 of emptying equipment 20 and whole pyriform.
Emptying equipment 20 is made up of the roller 22,23 of at least one or two, and roller 22,23 links together by the system of bar 24, thereby the distance between the axle of roller 22 and 23 can change.
Flexible container 21 comprises that mechanically robust wall elements 25 and glue bond are incorporated into the liner bag 26 of wall elements 25 inside faces.Flexible container 21 also is equipped with delivery channel 27 in its underpart, it links to each other with the mechanical collection device of being made up of pump 28.Relative, flexible container 21 has lifting or suspension handle 29 on top.
Solid line among Fig. 3 is represented the situation before the pressurization of emptying external member, and long and short dash line is represented the situation of emptying external member when the pressurization beginning.
As horizontal arrow representative among the figure, roller 22,23 is drawn close each other so that push the top of flexible container 21.The roller of drawing close each other by this way 22 and 23 then begins to descend as vertical arrows is represented.Flexible container 21 thereby be extruded gradually to the lower end from its upper end.Viscous product 2 withstanding pressures and the delivery channel 27 of flowing through that container 21 is contained, this pressure depends on the intensity of container.By using pump 28 that viscous product 2 is taken out.
Can find that pressurization has the effect that container 21 is remained in swelling state by reducing roller 22,23.
In fact, the handle 29 of flexible container 21 passes through between roller 22,23, and handle 29 is for example used forklift truck lifts.By being used to control bar 24 systems of interior wheelbase, roller 22,23 is tightened up at the either side on flexible container 21 tops.Roller 22,23 descends under himself action of gravity along flexible container 21, and viscous product 2 is promoted downwards up at the gravity of roller 22,23 be compressed between the antagonistic force of flexible container 21 and form balance.
When discharge orifice 27 was opened, viscous product 2 (for example silicone putty) flowed, and roller 22,23 descends, and pushes all the elements thing in the flexible container 21 gradually.
In this embodiment, for example with about 35 liters/minute operated in flow rate, its discharge orifice has the diameter of 33cm, and two steel rider diameters are 10cm, and weight is 40kg (in order to adhere on the flexible container 21 the steel rider rubber-coated well).The liner bag of flexible container 21 by gluing combination or sutured to exterior polypropylene fabric wall elements 25.
The mechanization of system is provided, both flexible container 21 can be pulled through slack-free roller 22,23 and/or also can roller 22,23 self mechanization rotation.Such mechanization only can increase the exit velocity of viscous product 2.
Use pump 28 can significantly increase the exit velocity (x10) of viscous product 2.
By the following example, replenish and describe first embodiment.
