Description
Technical field
The utility model relates to grind away tank technical field, especially a kind of simple and reliable vacuum grind away tank.
Background technology
Shale gas research is a hot fields of current petroleum gas research.In the shale gas research process, an important content is after shale is pulverized, and measures the gas flow of its release, and the isotope value of mensurated gas composition; And the pulverizing of shale is to complete in vacuum tank, requiring sample to pulverize front container will be evacuated, and in crushing process, container can not leak gas, and pulverizes the rear pump-line of end and can not stop up.And do not meet in the market the vacuum grind away tank of above requirement, for this reason, need a kind of vacuum grind away tank that prevents that dust from stopping up of development badly.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provide a kind of simple in structure, reliable, can prevent that dust from stopping up the vacuum grind away tank of pump-line.
To achieve these goals, the technical solution adopted in the utility model is: a kind of simple and reliable vacuum grind away tank, it is characterized in that: comprise tank body, the cover and the extraction valve that are tightly connected with tank body, extraction valve comprises valve body, pressure cap and motion bar, valve body is provided with inlet channel and outlet passageway, offer the opening that is communicated with inlet channel on valve body, pressure cap is threaded connection and is provided with the through hole corresponding with opening with valve body, the bottom of motion bar can and can be moved through through hole and opening in inlet channel, also be provided with an O-ring seal between valve body openings place and pressure cap, inlet channel inflow point at valve body is provided with filter cotton, the outlet passageway exit is equipped with a valve, valve is connected with a T-valve by flexible pipe, two outlets of T-valve are connected with vacuum pump with gas chromatograph respectively.
Described cover comprises lid, and the edge of lid is stepped, is extended with the flange adapted with described tank body opening inwall on the lid bottom surface downwards.
Be set with O-ring seal on described flange.
Described motion bar upper end is fixed with pin, between pin and pressure cap, is provided with back-moving spring.
The beneficial effects of the utility model: simple in structure, reliable, easy to use, by adopting the structure of above-mentioned extraction valve, in the inlet channel import, filter cotton is set, in process of lapping, can blocks powder stops up breather line, and after sample has ground, by motion bar, can under the condition of not destroying vacuum, make the filter cotton polluted by powder come off, make gas circuit along logical, thoroughly solve the blockage problem of admission line.
Cover is clamped on tank body by flange, and O-ring seal guarantees to be tightly connected between tank body and cover.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of simple and reliable vacuum grind away tank of the utility model, the cover 2 and the extraction valve 3 that comprise tank body 1, be tightly connected with tank body.
Extraction valve 3 comprises valve body 31, pressure cap 32 and motion bar 33, valve body 31 is provided with inlet channel 34 and outlet passageway 35, offer the opening that is communicated with inlet channel on valve body 31, pressure cap 32 is threaded connection and is provided with the through hole corresponding with opening with valve body, the bottom of motion bar 33 can be through through hole and opening and can be in the interior movement of inlet channel 34, also be provided with an O-ring seal 36 between valve body 31 opening parts and pressure cap 32, inlet channel inflow point at valve body is provided with filter cotton 37, outlet passageway 35 exits are equipped with valve 38, valve 38 is connected with T-valve 5 by flexible pipe 4, two outlets of T-valve 5 are connected with vacuum pump 7 with gas chromatograph 6 respectively.Be fixed with pin 39 in motion bar 33 upper ends, between pin 39 and pressure cap 32, be provided with back-moving spring 8.
In the present embodiment, above-mentioned cover 2 comprises lid 21, and the edge of lid 21 is stepped, is extended with the flange 22 adapted with tank body opening inwall on the lid bottom surface downwards; Be set with O-ring seal 23 on flange 22.So, the O-ring seal 23 of chucking can guarantee that tank body 1 and cover 2 are tightly connected, and there is gap in cover 2 because being provided with stair-stepping lid 21 between its edge and tank body, in the time of need to opening cover, can pry open from gap, the convenient cover 2 that takes out.
Workflow of the present utility model is: 1, cover 2 is taken off from tank body 1; Filter cotton 37 is filled in inlet channel 34; Steel ball 9 and sample 10 are put into to tank body 1; Then cover 2 is pressed into to tank body 1, both are tightly connected by chucking.
2, open the valve 38 on 35 mouthfuls of outlet passageways, and rotate T-valve 5, valve 38 is communicated with vacuum pump 7, open vacuum pump 7, to vacuumizing in the grind away tank.
3, valve-off 38, rotate T-valve 5 it is connected with gas chromatograph 6; Take off flexible pipe 4 simultaneously.
4, tank body 1 is placed on the planetary mills model machine, make the rotation of grind away tank, thereby steel ball and sample generation frictional impact grinds sample, discharge gas; Grind away takes off the grind away tank after finishing from the planetary mills model machine, flexible pipe 4 is connected valve 38 and T-valve 5.
5, rotate T-valve 5, vacuum pump 7 is communicated with valve 38.Rotate T-valve 5 after 1 minute, valve 38 and gas chromatograph 6 are communicated with, and motion bar 33 is moved down, the filter cotton 37 that sticks dust is ejected, make inlet channel 34 keep unimpeded.
