Description
Technical field
The utility model relates to vacuum generating equipment, especially a kind of matching used series connection steam jet vaccum of medical department sterilization tank that is used for.
Background technique
Vacuum for industrial use generation equipment mainly can divide two classes at present, and a class is the mechanical volume vacuum pump, and a class is the jet type vacuum pump.The mechanical volume vacuum pump is by mechanical motion to be changed in the pump chamber swept volume generation cycle, realizes bleeding function.Common mechanical volume vacuum pump has sliding valve style, rotary sheet type, water ring type.The revolving part or the reciprocating part of mechanical volume vacuum pump wear and tear easily, need often maintenance, and working life is short.The jet type vacuum pump mainly is to penetrate at a high speed by nozzle by working medium, makes the outlet area of nozzle form huge negative pressure, realizes the function that vacuumizes to container.The jet type vacuum pump does not have mechanical moving element, and is simple in structure, easy to operate, and long service life obtains extensive use in chemical industry, light industry and food industry.With steam be medium the jet type vacuum pump expanded application on medical sterilizing equipment decontaminating apparatus, and obtain good effect.The problem that exists is that the condensed water in the condenser is discharged difficulty, is the condenser draining, even has to erect condenser is high, has both increased equipment occupation space, has increased mounting cost, brings very big inconvenience to behaviour person simultaneously.
Summary of the invention
The purpose of this utility model is the problem of the condenser draining difficulty that exists at the jet type vacuum pump that at present is medium with steam, provide a kind of exhaust and draining to carry out simultaneously, by two vapor pumps and the series connection steam jet vaccum that condenser is connected in series.
Series connection steam jet vaccum described in the utility model comprises one-level vapor pump, second steam jet pump, condenser and noise reduction cooler.Noise reduction cooler and condenser end-to-end, sealing is connected.The condenser front end is provided with cooling water intake.Noise reduction cooler rear end is provided with coolant outlet.The exhaust port of one-level vapor pump is communicated with the rear portion of condenser.The exhaust port of second steam jet pump is communicated with the noise reduction cooler.The bleeding point of second steam jet pump is communicated with the front portion of condenser.
The one-level vapor pump is made of first order jet nozzle, one-level mixing chamber, one-level diffuser pipe and one-level elbow.First order jet nozzle is loaded in the one-level mixing chamber.One-level mixing chamber, one-level diffuser pipe and one-level elbow seal successively and are connected.
The second steam jet pump is made of secondary nozzle, secondary mixing chamber, secondary diffuser pipe and secondary elbow.Secondary nozzle is loaded in the secondary mixing chamber.Secondary mixing chamber, secondary diffuser pipe and secondary elbow seal successively and are connected.
First order jet nozzle, secondary nozzle, one-level diffuser pipe and secondary diffuser pipe are the Laval nozzle structure.
Condenser is a shell and tube condenser.
Series connection steam jet vaccum described in the utility model can constitute series connection steam jet vaccum unit by plural vapor pump and two above condenser series connection.
During work, the bleeding point of one-level vapor pump is taken out container with quilt and is connected, and is 3kg/cm with pressure respectively with the first order jet nozzle of one-level vapor pump and the secondary nozzle of second steam jet pump
2Steam line connect, be 3kg/cm with the cooling water intake and the pressure of condenser
2Cooling water pipeline connect and just can vacuumize work, condensed water can pass through the drain opening discharge from the noise reduction cooler of condensing air, noise reduction cooler.
The utility model has the advantages that simple in structure, easy to operate, long service life, simultaneously condenser discharge convenient.
