Description
Technical field
The utility model relates to a kind of vacuum high frequency that is applied in solar vacuum heat-collecting pipe hollow billet inwall plated film field and moves evaporator.
Background technology
At present, solar vacuum heat-collecting pipe hollow billet inwall plated film generally adopts chemically plating, and the product specular reflectance that this method is coated with does not reach requirement, and scrap rate is too high, therefore technology and the support equipment that needs development to make new advances.
As everyone knows, in the aluminized main equipment of continous vacuum, the high-frequency induction heating evaporation process achieves satisfactory results on steel band.The high-frequency induction evaporation source is will the graphite of evaporating materials or the frequency spiral coil central authorities that ceramic crucible is placed on water-cooled be housed, make evaporating materials under the induction of high frequency band internal magnetic field, produce powerful eddy losses and hysteresis loss to ferro-magnetic, cause evaporating materials to heat up, until steam raising.The volume of film material is more little, and the induced frequency is just high more.In addition, vacuumizing is a suitable proven technique, is widely used in the production of vacuum flask, all-glass vacuum thermal-collecting tube, vacuum plating etc.
For these reasons; my company finds out the vacuum high-frequency induction heating evaporation coating technology that a cover is applied in full-glass solar energy collecting vacuum tube hollow billet inwall plated film aspect; but realize mass mechanized production and guarantee coating quality and speed, must develop a kind of specific equipment that matches with technology.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned prior art; provide a kind of vacuum high frequency to move evaporator; can directly coat the reflectance coating of design radian easily according to valve tube mirror surface central angle size needs; and be applicable to mass mechanized production, raising that can be bigger plated film speed, guarantee coating quality.
The technical scheme taked of the utility model is to achieve these goals: a kind of vacuum high frequency moves evaporator, comprise evaporation boat, vacuum extractor and be arranged on high-frequency device in the mobile unwheeling, high-frequency device is provided with external radio-frequency coil and electro-magnet, the evaporation boat is located at hollow billet inside, the evaporation boat is provided with magnet, and hollow billet passes radio-frequency coil and inserts vacuum extractor.Move and to drive to drive that high-frequency device moves, electro-magnet and magnet adhesive campaign.Utilize the pre-essence of vacuum extractor to take out, guarantee that the hollow billet internal vacuum of glass satisfies the arts demand that is coated with reflectance coating; The high frequency magnetic field that high-frequency device produces by the induction heating radio-frequency coil makes the evaporation material in the evaporation boat produce powerful eddy losses and hysteresis loss heats up, and until steam raising, evaporating materials is met the hollow billet wall cooling and attached on the hollow billet inwall; High-frequency device is installed on the mobile unwheeling, realize the motion that the relative hollow billet of radio-frequency coil is sent out by mobile unwheeling campaign, the electro-magnet that is fixed on the high-frequency device attracts the magnet on the inner evaporation of the hollow billet boat to make it to form strong magneticaction, traction control in-tube evaporation boat moves, final evaporation heating source (radio-frequency coil) and the evaporation boat realized is synchronized with the movement, can directly coat the reflectance coating of design radian easily according to valve tube mirror surface central angle size needs, and obtain continuously uniformly reflectance coating, the speed of travel by controlling mobile unwheeling and high-frequency device and the frequency of high-frequency device are controlled the thickness of rete, realize the quality of stability of plated film.Thereby greatly reduce vacuum plating because of heating source is removable to the requirement of vacuum operating spatial, do not need to build big vacuum chamber, saved production cost, the pumpdown time is reduced greatly, improved production efficiency.
In order to realize mechanize scale operation, described mobile unwheeling is provided with many high-frequency devices, and corresponding vacuum extractor is provided with a plurality of bell and spigots.
The beneficial effects of the utility model are: plated film compared to existing technology, the utility model can directly coat the reflectance coating of design radian according to valve tube mirror surface central angle size, and be applicable to mass mechanized production, raising that can be bigger plated film speed, guarantee coating quality; Thereby greatly reduce vacuum plating to the requirement of vacuum operating spatial because heating source is removable, do not need to build big vacuum chamber, saved production cost, the pumpdown time is reduced greatly, improved production efficiency.
