Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of the term used in specification of the present utility model herein just in order to describe concrete mode of execution, is not intended to be restriction the utility model.Term as used herein " and/or " comprise arbitrary and all combinations of one or more relevant Listed Items.
Refer to Fig. 1, the vacuum pumping device 100 of present embodiment comprise liquid-collecting box 110 for being communicated with exhaust outlet, conduit 120, for storing the water tank 130 of liquid, outlet pipe 140, solenoid valve 150 and vacuum pump 10.One end of conduit 120 is communicated with liquid-collecting box 110, and the other end immerses in the liquid of water tank 130.One end of outlet pipe 140 is used for being communicated with vacuum pump 10, and the other end and water tank 130 are tightly connected.Solenoid valve 150 is located on outlet pipe 140, solenoid valve 150 and outlet pipe 140 conducting.
Waste gas is discharged through liquid-collecting box 110 from exhaust outlet (not shown), enters conduit 120 by liquid-collecting box 110.Waste gas enters in the liquid of water tank 130, and through liquid cooling, filter and discharge from water tank 130, waste gas enters outlet pipe 140, and final waste gas is discharged by vacuum pump.In the process using above-mentioned vacuum pumping device, if the fault of meeting accident, solenoid valve 150 cuts out, forbid that exhaust gas recirculation is in water tank 130, liquid in water tank 130 is pressed into liquid-collecting box 110 li, and prevents liquid from entering in manufacturing mechanism from liquid-collecting box 110, damage equipment.In thermoplastics processing field, the liquid in water tank 130 enters in manufacturing mechanism, can also affect the quality of product of thermoplastic.
In other embodiments, vacuum pump 10 is Nash hytor.Solenoid valve 150 can also prevent liquid backflow in Nash hytor in outlet pipe 140, and enters in water tank 130.
The diapire of liquid-collecting box 110 offers suction port 111, and suction port 111 is for being communicated with exhaust outlet.Waste gas enters liquid-collecting box 110 from suction port 111.The diapire of liquid-collecting box 110 is provided with the projection 113 of annular.Protruding 113 around the periphery of suction port 111 and the inside towards liquid-collecting box 110 arrange.Gap 115 is there is between protruding 113 and the sidewall of liquid-collecting box 110.The cooling such as the steam in waste gas forms little water droplet, and hydrops is formed on the bottom collecting in liquid-collecting box 110.Gap 115 is for accommodating hydrops.Due to the stop of protruding 113, hydrops can not enter into equipment from suction port 111, ensures the safe handling of equipment.
The outer side wall of protruding 113 is provided with inclined-plane 117, and inclined-plane 117 is acute angle with the angle of diapire.Namely when steam is when the roof of liquid-collecting box 110 or sidewall are cooled to little water droplet, water droplet enters in gap 115 along sidewall landing.And the little droplets form of roof falls into inclined-plane 117 from roof, and enters in gap 115 along inclined-plane 117 landing.
Specifically in the present embodiment, liquid-collecting box 110 is cylindrical.Inclined-plane 117 is conical surface.
The sidewall of liquid-collecting box 110 offers air outlet 119 near one end of diapire.Waste gas is discharged from air outlet 119.
Conduit 120 comprises straight tube 121 and the liquid-discharging tube 122 of mutual conduction.One end of straight tube 121 is immersed in liquid.Liquid-discharging tube 122 and straight tube 121 are obliquely installed.One end of liquid-discharging tube 122 is communicated with liquid-collecting box 110.Liquid-discharging tube 122 is communicated with air outlet 119 near one end of liquid-collecting box 110.Because liquid-discharging tube 122 is obliquely installed, then hydrops can flow in liquid-discharging tube 122 from air outlet 119, and hydrops enters straight tube 121 through liquid-discharging tube 122, then is entered in water tank 130 by straight tube 121, reaches the object of discharging hydrops.
Be appreciated that in other embodiments, conduit 120 is integral type bend pipe.
One end away from water tank 130 of straight tube 121 is provided with pipe close 123.Pipe close 123 and straight tube 121 are tightly connected.Pipe close 123 can be opened, straight tube 121 is cleaned.Facilitate the cleaning work after straight tube 121 incrustation.
The vacuum pumping device of present embodiment also comprises pressure gauge 160.Pressure gauge 160 is located on conduit 120.The air pressure in conduit 120 is regulated according to pressure gauge 160.
The above embodiment only have expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
