Having more or higher-energy electron beam participation energy exchange, such electron recovery device is also accomplished by consuming substantial amounts of energy, as
Really these energy can not be derived in time, it will causes electron recovery device to burn out.Therefore, it is possible to design the electricity of high cooling efficiency
Sub-withdrawer is particularly important.
Existing electron recovery device often structure is very complicated, manufactures welding sequence the most, it is easy to occur true
Empty leakage, cost is the highest.
Summary of the invention
For the deficiencies in the prior art, the purpose of the invention is to provide the purpose of this utility model and is to provide one
The electron recovery device that structure simplifies, its feature is simple for structure, through the most available qualified products of a step welding sequence, manufactures
Cost is substantially reduced, and it has high efficiency heat-sinking capability, many that weight ratio existing electron recovery device is light and handy.
For achieving the above object, the invention is realized by techniques below means:
The electron recovery device that a kind of structure simplifies, it is characterised in that: include ring flange, the insulation porcelain being connected with ring flange
Ring, is set in the electron recovery cylinder in ring flange and insulation porcelain ring centre bore, between sealed insulation porcelain ring and electron recovery cylinder between
The sealing drum of gap, is placed on the ceramic cylinder outside sealing drum and electron recovery cylinder, is provided with lead-in wire, described method bottom electron recovery cylinder
Between blue dish and insulation porcelain ring, between described sealing drum and insulation porcelain ring and electron recovery cylinder, between electron recovery cylinder and lead-in wire
Employing soldering connects.
Further:
Described electron recovery cylinder opening part is small-bore and becomes the shape and structure of falling horn mouth.
Described ring flange and sealing drum material use kovar alloy, and surface carries out electronickelling process, and thickness of coating is 0.009
~0.012mm。

The invention provides the benefit that: this utility model is simple for structure, weight is light and handy, cheap for manufacturing cost；Electronics
Recovery cylinder uses oxygenless copper material, and its beryllium oxide ceramics cylinder the most excellent with heat conductivility contacts, and shortens heat dissipation path,
Can effectively improve the heat-sinking capability of electron recovery device；Insulation porcelain ring uses 99-Al2O3 pottery, and its insulating capacity is very strong, electronics
Withdrawer uses relative to reducing voltage for O type device slow wave system voltage, improves electron recovery efficiency.
This utility model except can be used for O type vacuum device as electron recovery electrode in addition to, it is possible to be applicable to other needs
The device of electron beam recovery popularization and application.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with Figure of description, the invention is further described.
The electron recovery device that a kind of structure simplifies, is made up of six parts, and 1, ring flange；2, insulation porcelain ring；3,
Sealing drum；4, electron recovery cylinder；5, ceramic cylinder；6, lead-in wire.Described ring flange 1 and sealing drum 3 material use kovar alloy, surface
Carrying out electronickelling process, zinc coat thickness control is at 0.009 ~ 0.012mm；Described insulation porcelain ring 2 uses 99-Al2O3 pottery, pottery
Sealing surface uses sintering metal powder method molybdenum-manganese metal technique to metallize；Described lead-in wire 6 material uses diameter Ф 0.8
Nickel wire or the good copper wire of electric conductivity, length can the most freely be chosen；Described electron recovery cylinder 4 material uses anaerobic
Copper, in order to prevent recovery electronics generation reflection from coming back to O type device slow wave system, electron recovery cylinder 4 entry design becomes aperture
Footpath also becomes the shape and structure of falling horn mouth；Described ceramic cylinder 5 uses the beryllium oxide ceramics that heat conductivility is excellent.
Concrete assembly method is as it is shown in figure 1, be positioned over bottom by described ring flange 1；Then the above-mentioned institute of placement it is sequentially overlapped
State the insulation porcelain ring 2 metallized；Place sealing drum 3 described above；Place electron recovery cylinder 4 described above；On finally placing
State described lead-in wire 6.When specifically assembling, described ring flange 1, edge porcelain ring 2, sealing drum 3, electron recovery cylinder 4, lead-in wire 6 assembling
Time, connect and at gap, place PdAgCu20 solder.
