Specific implementation mode
The present invention provides a kind of exhaust apparatus of microwave dissolver, to make the purpose of the present invention, technical solution and effect more
Add clear, clear, the present invention is described in more detail for the embodiment that develops simultaneously referring to the drawings.It should be appreciated that described herein
Specific examples are only used to explain the present invention, is not intended to limit the present invention.
It please referring to Fig.1 with 2, the present invention provides a kind of exhaust apparatus of microwave dissolver, including：Shell 1 is arranged in shell
Blast pipe 2, exhaust duct 3 in 1, are completely covered on blast pipe 2 at the cooling tube 4 being connected between blast pipe 2 and exhaust duct 3
The first exhaust fan 5 of air inlet and be completely covered on exhaust duct 3 exhaust outlet second exhaust fan 6, be covered in first exhaust fan 5
The filter pad 7 of front end；The positive diagonal angle of the shell 1 offers the first mounting hole 11 and the second mounting hole 12 respectively, into
One end of air hose 2 is fixed on the first mounting hole 11, and the other end is fixedly connected with cooling tube 4, and one end of exhaust duct 3 is fixed on
On two mounting holes 12, the other end is fixedly connected with cooling tube 4, and first exhaust fan 5 and second exhaust fan 6 open and close simultaneously.
The exhaust apparatus is used for mounted on the back of microwave dissolver, and the gas of microwave dissolver inner cavity is by filtering
Net, certain harmful components in gas are adsorbed, and are then entered in blast pipe 2 through first exhaust fan 5, are entered by blast pipe 2
It is cooled after cooling tube 4, is then vented back in the inner cavity of microwave dissolver through exhaust duct 3, so recycled, until micro-wave digestion
The temperature of instrument inner cavity is down to safe range.First exhaust fan 5 and second exhaust fan 6 are driven by motor, are realized while being opened and closing
It closes, ensures that gas circuit is unimpeded.The exhaust apparatus of microwave dissolver using the above structure can make the temperature of microwave dissolver inner cavity
Rapid decrease reduces the required time that cools down, and improves the efficiency of work, and gas is wherein entrained in cyclic process
Harmful components adsorbed by filter screen, avoid being expelled directly out atmospheric environment and causing damages to environment, also avoid experimenter
Suck and endanger the health of experimenter.
Further, the cooling tube 4 includes outer tube 42 and inner tube 41, and inner tube 41 is completely encapsulated in inside outer tube 42, interior
The both ends of pipe 41 are closely connect with blast pipe 2 and exhaust duct 3 respectively, and the caliber of the junction blast pipe 2 and exhaust duct 3 with
Inner tube 41 is consistent.When air exhausting device work, gas is from the inner tube 41 that blast pipe 2 enters cooling tube 4, and cooling water is from outer tube
It is flowed in 42, cools down the direction of flow with the direction of gas flowing on the contrary, enhancing the effect of heat exchange to a certain extent, accelerate
The cooling rate of gas.
Further, the both ends of the outer tube 42 are closely connect with the outer wall of blast pipe 2 and exhaust duct 3 respectively.
Further, water inlet 421 and water outlet 422, the water inlet are respectively equipped on the side wall at 42 both ends of the outer tube
Mouth 421 and water outlet 422 are each passed through the side wall of the shell 1 of the exhaust apparatus.The outer wall and outer tube of the inner tube 41 of cooling tube 4
The 422 closed space other than water inlet 421 and water outlet is formed between 42 inner wall, has been fully ensured that leakproofness, has been prevented from cooling down
Water enters the inner cavity of microwave dissolver by pipeline, influences the normal work of instrument.
Preferably, said inner tube 41 is in the shape of a spiral；When spiral helicine inner tube 41 increases stop of the gas in cooling tube 4
Between, so that it is fully carried out heat exchange with cooling water, improves the utilization rate of cooling water.
Preferably, the caliber of the air inlet of the blast pipe 2 is bigger than the caliber of air outlet, the air outlet of the exhaust duct 3
Caliber it is bigger than the caliber of air inlet.After entering blast pipe 2, the air inlet bigger from caliber flows gas to cooling tube 4,
Caliber narrows, and the flow velocity of gas is accelerated, and entering the inner tube 41 of cooling tube 4 for it provides power, makes gas not because spiral helicine cold
But 4 inner tube 41 of pipe and flow over slow, cause the speed that gas is discharged more many than the speed of inflow and cause the difference of air pressure, to
Cause inner tube 42 to be damaged, after the gas of outflow inner tube 42 enters exhaust duct 3, direction that the caliber of exhaust duct 3 is flowed with gas by
Gradual change is big, and the flow velocity of gas is slack-off with the increase of caliber, and the air pressure in entire air duct is kept to be in a normal fluctuation model
It encloses, also makes the flow velocity for the gas for entering microwave dissolver inner cavity from air outlet slack-off, it is excessive to micro-wave digestion to reduce airflow fluctuation
The influence of instrument inner cavity environment.
Referring to Fig. 3, further, the filter pad 7 includes strainer 71 and adsorption layer 72, the adsorption layer 72 is wrapped in
In strainer 71.
Preferably, the sorbing material of the adsorption layer 72 includes activated carbon and quick lime.The digestion solution of general micro-wave digestion
For acid solutions such as nitric acid, sulfuric acid, the acid solution can be absorbed after activated carbon and quick lime, to make gas be purified, and
And the cost of activated carbon and quick lime is low, so that timing is replaced filter pad and is unlikely to that cost is excessively high, the day of compound Routine Test Lab
It is often used.
It, can according to the technique and scheme of the present invention and its hair it is understood that for those of ordinary skills
Bright design is subject to equivalent substitution or change, and all these changes or replacement should all belong to the guarantor of appended claims of the invention
Protect range.
