Abstract
The invention relates to a vacuumizing device for a vacuum oven. The vacuumizing device comprises a vacuum pump, a condenser and a receiving bottle, wherein an air inlet is formed in the body of the receiving bottle; a bottle mouth of the receiving bottle is arranged upwards; an air inlet of the condenser is connected with the bottle mouth of the receiving bottle, and an air outlet of the condenser is connected with an air suction hole of the vacuum pump by a pipeline; the air outlet of the condenser is higher than the air inlet of the condenser. After the scheme is adopted, the vacuum pump is effectively protected, the service life of the vacuum pump is prolonged, the vacuum degree is guaranteed during formulation proportion every time, and the accuracy of small sample production is improved.
Description
Technical field
The technical program belongs to technical field of chemical, specifically a kind of vacuum extractor for vacuum drying oven.
Background technology
In prior art, research and development organosilicon sealant formulation ratio need carry out sample making, in manufacturing process, need raw material and semi-finished product sizing material to carry out the de-low-boiling-point substance processing of high temperature, vacuum drying oven is common de-low-boiling-point substance experimental facilities in laboratory, during use, need to be connected with vacuum oil pump, vacuum drying oven is vacuumized, when the de-low-boiling-point substance of high temperature is processed, in baking oven, can produce a large amount of heats and low-boiling-point substance to vacuum oil pump generation high temperature corrosion, affect the service life of vacuum oil pump, and reduction vacuum, sample is made to result certain influence.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the technical program proposes a kind of vacuum extractor for vacuum drying oven, comprises vavuum pump, condenser and receiving bottle; On described reception bottle, drive gas port into, the bottleneck of receiving bottle upward; The air inlet of described condenser is connected on the bottleneck of receiving bottle, and the gas outlet of condenser connects the bleeding point of vavuum pump by pipeline; The gas outlet of described condenser is higher than the air inlet of condenser.
Also comprise incubator, cold neck is housed in incubator, outside the cold neck of incubator; The cold neck external space in described incubator is filled cooling thing.
Described receiving bottle is glass receiving bottle, and specification is 2000ml; Described condenser is glass condenser, and specification is diameter 24cm, high 600cm; Described cold neck is the cold neck of glass, and specification is 250ml.
Described cooling thing is ice cube.
Described vavuum pump is vacuum oil pump.
The principle of this device is, vacuum drying oven bleeding point is connected with condenser, and condenser is connected with of the cold neck of glass again, and other end is connected with vacuum oil pump again.While vacuumizing de-low-boiling-point substance, in vacuum drying oven, a large amount of hot gas of generation and low-boiling-point substance first pass through the cooling most of heat of condenser and low-boiling-point substance.Do not have cooling part heat and low-boiling-point substance to continue through the cold neck in incubator cooling, in incubator, being placed with ice cube has better cooling effect to heat and low-boiling-point substance.When the gas in vacuum drying oven arrives vacuum oil pump; gas has been cooled and low-boiling-point substance is also condensate in condenser and cold neck, has effectively protected vacuum oil pump, has extended service life; and the vacuum while having guaranteed at every turn to do formulation ratio, improves the accuracy that sample is made.
Accompanying drawing explanation
Fig. 1 is the structural principle schematic diagram of this cooling device;
In figure: vacuum drying oven 1, receiving bottle 2, condenser 3, incubator 4, cold neck 5, vavuum pump 6.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the technical program is further illustrated as follows:
As Fig. 1, a kind of vacuum extractor for vacuum drying oven, comprises vavuum pump, condenser and receiving bottle; On described reception bottle, drive gas port into, the bottleneck of receiving bottle upward; The air inlet of described condenser is connected on the bottleneck of receiving bottle, and the gas outlet of condenser connects the bleeding point of vavuum pump by pipeline; The gas outlet of described condenser is higher than the air inlet of condenser.Also comprise incubator, cold neck is housed in incubator, outside the cold neck of incubator; The cold neck external space in described incubator is filled cooling thing.
In this example, described receiving bottle is glass receiving bottle, and specification is 2000ml; Described condenser is glass condenser, and specification is diameter 24cm, high 600cm; Described cold neck is the cold neck of glass, and specification is 250ml.Described cooling thing is ice cube.Described vavuum pump is vacuum oil pump.
