Abstract
A condensing device of a vacuum drying tank belongs to the condensing device technical field. The condensing device of the vacuum drying tank comprises a water tank, a condenser, a water storage tank, a filter, a roots pump, a baffle valve and an exhaust duct. The exhaust duct is divided into an upper exhaust duct, a lower exhaust duct and a thin exhaust duct. A vacuum port above the roots pump is connected with the condenser through the upper exhaust duct. A vacuum port below the roots pump is connected with a vacuum port of a rotary vane pump through the lower exhaust duct. The rotary vane pump is connected with the filter. The thin exhaust duct is connected between the upper exhaust duct and the lower exhaust duct. Pneumatic valves are installed on both the lower exhaust duct and the thin exhaust duct. The exhaust duct between the condenser and the vacuum pump is arranged into ducts of different thickness, an operator can conduct switching between the upper exhaust duct and the thin exhaust duct according to requirements to change speed of air exhaust and then to change residence time of air in the condenser. Not only good condensing effect is achieved, but also the vacuum drying tank can achieve a qualified vacuum degree.
Description
Technical field
The utility model relates to a kind of condensing unit, particularly relates to a kind of condensing unit for vacuum drying tank.
Background technology
At present, the basic ideas of existing condensing unit for vacuum drying tank are in the industry: gas enters into condenser after drying chamber is extracted out, condensation through condenser, hydrogenesis in the gas becomes aqueous water to discharge, a discharge duct is installed on the condenser, and condensed gas enters in the vavuum pump through this pipeline.Because the condensation process of drying chamber is condensation while vacuumizing, if so go for good condensation effect, the sufficient condensation time of gas should be given, and existing condensing unit reaches the use standard for the vacuum that can make drying chamber, the discharge duct diameter of installing on the condenser is all very big, and this is short and can't obtain good condensation effect with regard to the time of having caused the gas extracted out from drying chamber to stop condenser.Enter vavuum pump if contain the gas of moisture, go down for a long time and will vavuum pump be caused damage.
Summary of the invention
It is reasonable that the purpose of this utility model just provides a kind of features simple structure, can make gas obtain the condensing unit that good condensation effect can make the vacuum of drying chamber novel evacuated drying chamber up to standard again.
The technical scheme of the utility model technical solution problem is to achieve these goals: the condensing unit of vacuum drying tank, comprise water tank, condenser, water tank, filter, lobe pump, flapper valve, discharge duct, the flapper valve bottom is connected with the drying chamber vacuum port by pipeline, sidepiece is connected the rear portion of condenser by pipeline, water tank links to each other with water jacket in the condenser, water tank is installed in the below of condenser, it is characterized in that: described discharge duct is divided into discharge duct, following discharge duct and thin discharge duct, lobe pump top vacuum port links to each other with condenser by last discharge duct, the below vacuum port passes through down, and discharge duct links to each other with the vacuum port of sliding vane rotary pump, sliding vane rotary pump links to each other with filter, thin discharge duct is connected between discharge duct and the following discharge duct, on discharge duct and the thin discharge duct operated pneumatic valve is being installed all down.
The described diameter of discharge duct of going up is greater than the diameter of thin discharge duct.
Operated pneumatic valve on the described discharge duct down is higher than the tie point of thin discharge duct and following discharge duct.
The beneficial effects of the utility model: the utility model adopts said structure, discharge duct between condenser and the vavuum pump is arranged to the pipeline of different thicknesses, operating personnel can be switched between last discharge duct and thin discharge duct as required, select suitable discharge duct to bleed, the speed of bleeding with change, and then change the time of staying of gas in condenser, can obtain good condensation effect and can make drying chamber reach qualified vacuum again.The utility model is rational in infrastructure, through experiment and work on the spot confirmation effect is remarkable repeatedly, satisfies the demand in market greatly, has social benefit and market prospects widely.
Description of drawings
Fig. 1 is the structural representation of facing of the present utility model.
Fig. 2 is plan structure schematic diagram of the present utility model.
Fig. 3 is side-looking structural representation of the present utility model.
Major part among the figure: 1, go up discharge duct, 2, lobe pump, 3, the operated pneumatic valve I, 4, thin discharge duct, 5, discharge duct down, 6, water tank, 7, condenser, 8, sliding vane rotary pump, 9, flapper valve, 10, the operated pneumatic valve II, 11, water tank, 12, filter.
The specific embodiment
As Figure 1-3, the condensing unit of vacuum drying tank, comprise water tank 11, condenser 7, water tank 6, filter 12, lobe pump 2, flapper valve 9 and discharge duct, flapper valve 9 bottoms are connected with the drying chamber vacuum port by pipeline, sidepiece is connected the rear portion of condenser 7 by pipeline, water jacket in water tank 11 and the condenser 7 links to each other, water tank 6 is installed in the below of condenser 7, described discharge duct is divided into discharge duct 1, following discharge duct 5 and thin discharge duct 4, lobe pump 2 top vacuum ports link to each other with condenser 7 by last discharge duct 1, lobe pump 2 below vacuum ports pass through down, and discharge duct 5 links to each other with the vacuum port of sliding vane rotary pump 8, sliding vane rotary pump 8 links to each other with filter 12, thin discharge duct 4 is connected between discharge duct 1 and the following discharge duct 5, the diameter of last discharge duct 1 is greater than the diameter of thin discharge duct 4, at following discharge duct 5 operated pneumatic valve I 3 are installed, at thin discharge duct 4 operated pneumatic valve II 10 is installed, the operated pneumatic valve I 3 on the following discharge duct 5 is higher than the tie point of thin discharge duct 4 and following discharge duct 5.
Operation principle of the present utility model: the starting stage that drying chamber is being vacuumized, open flapper valve 9 and operated pneumatic valve II 10, close operated pneumatic valve I 3, make discharge duct 1 inoperative, gas enters and carries out condensation in the condenser 7 after extracting out from drying chamber, and the aqueous water that condensation is got off flows in the water tank 6, condensed gas is sent in the sliding vane rotary pump 8 by discharge duct 5 under thin discharge duct 4 warps, finally by being discharged by filter 12.Because moisture is bigger in the gas of this stage extraction, should allow gas in condenser 7, stop the long time, the moisture in the gas is condensed away fully, therefore need allow thin discharge duct 4 keep unimpeded.After after a while, the moisture of gas reduces in jar, even the time that stops in condenser 7 is short, moisture wherein also is enough to obtain condensation, reaches qualified vacuum in order to make drying chamber, closes operated pneumatic valve II 10 this moment, open operated pneumatic valve I 3, allow discharge duct 1 play a role, strengthen the vacuum pumping speed, this moment, gas was discharged through lobe pump 2, following discharge duct 5, sliding vane rotary pump 8, filter 12 successively from last discharge duct 1.In whole process, the condensed water in the water tank 11 is circulate between the water jacket of condenser 7 and water tank 11 under the effect of water pump always, for condenser provides cooling source.
