Description
Technical field
The utility model relates to oxygen content detection technique field, specifically a kind of oxygen content on-line detecting system.
Background technique
Currently, generally require technical process whole process to detect oxygen content index with the equipment under inert atmosphere, by
A large amount of steam, colloid can be generated during heat treatment in portioned product, and being directly entered oxygen conten analyser will lead to instrument
Damage；In addition, due to the oxygen in filter can not Rapid replacement it is thorough, cause in burner hearth oxygen content index to have with measured value larger
Difference, so that the air consumption of equipment be made to increase.
Utility model content
The purpose of the utility model is to provide a kind of oxygen content on-line detecting systems can quickly be set using reverse blow
The oxygen to swap out in signal piping and filter, and filter is reversely cleared up, it is able to extend the service life of filter core, is reduced with reaching
The purpose of air consumption and production cost.
The technical solution of the utility model is as follows:
A kind of oxygen content on-line detecting system includes that the burner hearth connect, coarse filtration filter, fine filtering are sequentially connected by pipeline
Filter and oxygen conten analyser, it is characterised in that: be equipped between the burner hearth and coarse filtration filter in the pipeline
First valve, pipeline bypasses between the coarse filtration filter and the first valve purging gas exhaust piping, the purging exhaust
Second valve is installed in pipeline；Third is installed between the fine filtering filter and oxygen conten analyser in the pipeline
Valve, pipeline bypasses between the fine filtering filter and third valve purging air inlet pipeline, the purging air inlet pipeline
In the 4th valve is installed.
The oxygen content on-line detecting system, it is characterised in that: the filtering accuracy of the coarse filtration filter is 5 μm, carefully
The filtering accuracy for filtering filter is 1 μm.
The oxygen content on-line detecting system, it is characterised in that: first, second, third and fourth valve is all made of electromagnetism
Valve.
The oxygen content on-line detecting system, it is characterised in that: the pipeline is in the coarse filtration filter and first
Tee tube is used between valve, the input end of the tee tube is connected with the outlet end of first valve, and the one of tee tube
A outlet end is connected with the input end of the coarse filtration filter, another outlet end of tee tube and the purging exhaust pipe
Road is connected.
The utility model has the beneficial effects that
The utility model structure is simple, using reverse blow, can Rapid replacement go out the oxygen in signal piping and filter,

Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
Referring to Fig. 1, a kind of oxygen content on-line detecting system includes that the burner hearth 1 connect, coarse filtration are sequentially connected by pipeline 5
Filter 2, fine filtering filter 3 and oxygen conten analyser 4 are equipped with first between burner hearth 1 and coarse filtration filter 2 in pipeline 5
Valve 6, pipeline 5 bypasses between coarse filtration filter 2 and the first valve 6 purging gas exhaust piping 7, purges and pacifies in gas exhaust piping 7
Equipped with the second valve 8；Third valve 9 is installed between fine filtering filter 3 and oxygen conten analyser 4, pipeline 5 exists in pipeline 5
Bypass has purging air inlet pipeline 10 between fine filtering filter 3 and third valve 9, purges in air inlet pipeline 10 and is equipped with the 4th valve
11。
In the utility model, the filtering accuracy of coarse filtration filter is 5 μm, and the filtering accuracy of fine filtering filter is 1 μm.
First, second, third and fourth valve 6,8,9,11 is all made of solenoid valve.
Pipeline 5 uses tee tube 12, the input end of tee tube 12 and first between coarse filtration filter 2 and the first valve 6
The outlet end of valve 6 is connected, and the one outlet end of tee tube 12 is connected with the input end of coarse filtration filter 2, tee tube 12
Another outlet end with purging gas exhaust piping 7 be connected.
The utility model is further described below in conjunction with attached drawing:
Oxygen content on-line detecting system is built and formed according to above structure, is first turned on second, four valves 8,11, is closed
First and third valve 6,9, high pure nitrogen/argon gas that 0.1-0.2Mpa is passed through into pipeline 5 by purging air inlet pipeline 10, purging 2
Minute or so, this makes it possible to Rapid replacements to go out the oxygen in pipeline 5 and coarse filtration filter 2 and fine filtering filter 3, and can be anti-
To cleaning coarse filtration filter 2 and fine filtering filter 3；Then the first and third valve 6,9 is opened, second, four valves 8,11 are closed, this
Sample oxygen conten analyser 4 can carry out on-line checking to oxygen content.
Above embodiment is only that the preferred embodiment of the utility model is described, not to the utility model
Protection scope be defined, under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art to this
The modification and improvement that the technical solution of utility model is made should all be fallen into the protection scope of the utility model.
