Abstract

A kind of structure of pass sheet chamber room exhaust pipe front end filtering fragment, including:Sunk screw, outer cover and gear core.Gear core is fastened with outer cover by sunk screw.It is formed with multiple vent grooves on the gear core;The edge of the outer cover is formed with boss.The diameter of above-mentioned outer cover is bigger than the diameter for keeping off core, and the edge of the edge lug boss and gear core of outer cover forms certain gap.In use, after the gas of cavity is introduced into outer cover and keeps off the gap of core, enter back into the groove of gear core, subsequently into bleed-off passage.And fragment is stopped by outer cover with gear outer core so that fragment cannot enter exhaust pipe, and then protect control valve and vacuum pump without damage.It is good filtration effect of the present invention, safe, the shock of potsherd can be born under sudden abnormal condition and is hardly damaged.Its simple in structure, convenient disassembly, it is reusable after simply clean.Semiconductive thin film equipment technical field can be widely used in.

Description

A kind of structure of pass sheet chamber room exhaust pipe front end filtering fragment
Technical field
The present invention relates to the structures that fragment is filtered in a kind of pass sheet chamber room exhaust pipe front end, this structure, which is mainly used in, partly to be led Body thin film deposits in preparation process, belongs to the applied technical field of semiconductor film film device.
Background technology
At the pass sheet chamber body bottom pumping mouth of semiconductor coated film equipment transmission module need that a kind of filtration is installed, to prevent Fragment is generated when ceramic manipulator collides under fortuitous event, and fragment can enter along pumping direction in control valve and in the pump housing It is caused to wear and is damaged.Designer uses filter screen sometimes, although filter screen can filter relatively large clast, Subtle powdered granule object is but easy to pour control valve from mesh infiltration, and then damages valve body.In addition, filter screen is broken by ceramics Piece is easily broken off when hitting, and is also easy in use by clogged with fragments, and actual filtration effect is poor.Therefore, it is badly in need of out The structure for filtering fragment of sending out exhaust pipe front end a kind of, while ensureing filter effect, can also increase the safety of equipment with Reliability.
Invention content
The present invention devises a kind of knot of pass sheet chamber room exhaust pipe front end filtering fragment for the purpose of solving the above problems Structure ensure that the safety and reliability of equipment while ensureing filter effect.
To achieve the above object, the present invention uses following technical proposals, a kind of pass sheet chamber room exhaust pipe front end filtering broken The structure of piece, including:Sunk screw, outer cover and gear core.Gear core is fastened with outer cover by sunk screw.It is formed on the gear core more A vent grooves;The edge of the outer cover is formed with boss.The diameter of above-mentioned outer cover is bigger than the diameter for keeping off core, the edge of outer cover The edge of boss and gear core forms certain gap.
In use, outer cover and gear core fastening composition filter are mounted on the top of cavity aspirating hole by sunk screw. After the gas of installation is complete rear chamber is introduced into outer cover and keeps off the gap of core, enter back into the groove of gear core, subsequently into pumping Channel.And fragment by outer cover with gear outer core stopped so that fragment cannot enter exhaust pipe, and then protect control valve and Vacuum pump is without damage.
After use, filter is taken out from cavity stomata, removes the sundries around cavity stomata, dismounting outer cover, gear core are simultaneously It is cleaned, it is reusable.
Beneficial effects of the present invention and feature are:
1, actual filtration effect is preferable, can prevent piece of debris from hitting, and block fragment prevents it from entering gas in filtering blocking Body pipeline also has certain filter effect to fine particulates;
2, safety is higher, firm in structure reliable, can be born under sudden abnormal condition the shock of potsherd without It is fragile, it is effectively protected the control valve and the pump housing of exhaust pipe rear end;
3, simple in structure, convenient disassembly is reusable after simply clean.

Fig. 3 is filter fundamental diagram of the present invention.
Specific implementation mode
Embodiment
With reference to attached drawing 1-3, a kind of structure of pass sheet chamber room exhaust pipe front end filtering fragment, including:It is sunk screw 1, outer Cover 2 and gear core 3.Gear core 3 is fastened with outer cover 2 by sunk screw 1.
It is formed with multiple vent grooves 4 on the gear core 3;
The vent grooves 4 can be made into round, rectangular or fan-shaped.
The quantity at least two of the vent grooves 4.
The edge of the outer cover 2 is formed with boss 5;
The diameter of the outer cover 2 is bigger than the diameter for keeping off core 3, and the edge lug boss 5 and the edge of gear core 3 of outer cover 2 are formed Certain gap.
In use, outer cover 2 and the gear fastening composition filter of core 3 are mounted on the upper of cavity aspirating hole by sunk screw 1 Side.The gas of installation is complete rear chamber is introduced into outer cover 2 and keeps off the gap of core 3, enters back into the groove 4 of gear core 3 and enters pumping Channel.And fragment is stopped by outer cover 2 with gear 3 outer wall of core so that fragment cannot enter exhaust pipe, and then protect control valve And vacuum pump is without damage.
After use, filter is taken out from cavity stomata, removes the sundries around cavity stomata, dismantles outer cover 2 and gear core 3 And cleaned, it is reusable.
Operation principle:Since the material of this structure is metal, therefore the shock of bulk ceramic fragment can be born without damaging.In Etc. the ceramic clasts of sizes will be blocked in filter area A (as shown in Fig. 3);Under suitable gas flow rate, subtle pottery Porcelain powder will be deposited on by gravity at filtration core root area B (as shown in Fig. 3);Gas itself then can be along attached drawing 3 Flow path achievees the purpose that gas filtration by filter.
