Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these mode of executions should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As depicted in figs. 1 and 2, a kind of vacuum pumping device, comprises base 1, and base is provided with vacuum pump 2, deposits the vacuum tank 3 of water, the bottom of vacuum tank 3 is provided with screw pump 4.Vacuum tank is upper tank body slight greatly, and the bottom of vacuum tank offers opening 31, and this opening is connected by flange seal with the material feeding mouth 41 of screw pump.The top of vacuum tank is provided with upper cover 32, and upper cover offers suction port 321, air outlet 322 and gas returning port 323 as shown in Figure 3, and suction port is connected with the Builking cavity of bulking machine by air intake valve 5, admission line 51.Air outlet is connected with vacuum pump 2 by outlet pipe 21, and the relief opening of vacuum pump is provided with exhaust duct 22, and the branch road 221 of exhaust duct is connected with the gas returning port 323 of upper cover by return air valve 222.
As shown in Figure 1, the screw pump 4 bottom vacuum tank, screw pump discharge port 42 is connected with flowmeter 43 and unidirectional stop valve 44 by pipeline, and unidirectional stop valve is by the equipment connection of pipeline and other workshop section.During normal work, in screw pump, the flow direction of material should be flow to flowmeter from screw pump, flow to unidirectional stop valve and flow to other equipment again; when the material in pipeline flows in the other direction; unidirectional stop valve stops flowing, thus the part that protection flow is taken into account in screw pump and vacuum tank is not damaged.
As shown in Figure 1, vacuum tank inside is provided with the float valve 6 detecting pot liquid height, and float valve is connected with water supply line.
As shown in Figure 2, the upper cover 32 of vacuum tank, be provided with air inlet elbow 324 at suction port 321 place of upper cover bottom side, in air outlet 322, place is provided with elbow 325 of giving vent to anger.In the water that the heat sucked from Builking cavity can better be discharged in vacuum tank by air inlet elbow and elbow of giving vent to anger.
During utility model works, water supply line works, under the effect of float valve, water level in vacuum tank keeps stable, it is air above it, vacuum pump works, the air of vacuum tank ullage is drawn out of, make to form negative pressure in vacuum tank, the branch road of vacuum pump discharges pipeline is communicated with vacuum tank by a return air valve and pipeline, by the size regulating the aperture of return air valve can control negative pressure in vacuum tank, because Builking cavity internal pressure is higher, some vapor in Builking cavity, moisture and small part material can be entered in vacuum tank by the admission line be connected on Builking cavity and merge with the aqueous phase in vacuum tank, form the mixtures of materials all having uniform temperature, steam in Builking cavity can be dissolved in the water in vacuum tank and be heated by water, through screw pump by the material in vacuum tank and delivery in the upstream equipment of bulking machine, achieve the recycling of material and energy.The utility model coordinates vacuum tank that the steam in bulking machine inner chamber and moisture are drawn into vacuum tank by using vacuum pump, it is made to mix with the water in vacuum tank, again mixed mixture is delivered to the upstream equipment of bulking machine through screw pump, thus reduce moisture and the expansivity of material in bulking machine, make material compactability stronger, be conducive to the production of heavy property material; Ensure that the quality of heavy property material, improve manufacturing efficiency, the utility model is particularly suitable in the production of heavy property material.
A lot of producer uses a bulking machine producing heavy property feed in turn, buoyancy feed.During production buoyancy feed, vacuum pumping device does not need work, at this moment the upstream equipment (as quality-adjusting device) of bulking machine is directly added in equipment by tap water by another pipeline, when operator's misoperation, tap water can flow backward in the vacuum tank of vacuum pumping device, causes the damage of part.Above the flowmeter of the discharge end of screw pump, increase unidirectional stop valve, effectively can avoid the generation of this problem, protect equipment.
