A kind of solar energy heat collection pipe exhaust equipment that does not have tailpipe
Technical field
The invention belongs to the solar energy utilization technique field, especially relate to a kind of solar energy heat collection pipe exhaust equipment that does not have tailpipe.
Technical background
To numerous the utilizing in the mode of solar energy, solar thermal utilization is that solar energy is directly changed into heat energy, and transformation efficiency is high, has obtained general applying.Vacuum glass tube solar heat-collecting technology is modal solar thermal utilization technology at present, and more representational is all-glass vacuum tube and hot pipe type vacuum heat collection pipe.These two kinds of thermal-collecting tubes generally need to weld tailpipe in advance in process at present, by tail pipe glass tube are carried out vacuumizing and exhausting.General tailpipe has two kinds, and a kind of is the glass tail pipe, and in advance sealing-in also is very easy to break even this glass tail pipe has added protective cap on glass tube, causes vacuum leak; Another is to carry out exhaust at the casting coping of hot pipe type vacuum heat collection pipe welding copper pipe, also exists because the bad vacuum leak that causes of welding quality.Simultaneously, the existence of tail pipe also can affect the attractive in appearance of product.At present, existing technology and equipment can't process the solar vacuum heat-collecting pipe that does not have tailpipe at all, and this is the upgrading that has limited product.
In order to address the above problem, we have invented a kind of solar energy heat collection pipe exhaust equipment that does not have tailpipe.
Summary of the invention
The object of the invention is to break away from tailpipe to the restriction of solar vacuum heat-collecting pipe, a kind of solar energy heat collection pipe exhaust equipment that does not have tailpipe is provided.
For realizing above purpose, the present invention takes following technical scheme:
A kind of solar energy heat collection pipe exhaust equipment that does not have tailpipe, it is used for solar energy heat collection pipe is carried out exhaust, comprise frame, frame is provided with air discharge duct, sealing ring is established at the air discharge duct top, the air discharge duct side is provided with high-temperature heating equipment or welder, the inside of described air discharge duct is provided with the propulsion plant that pushes for the inner tube with solar energy heat collection pipe and the thermal-collecting tube navigation system that is used for the location solar energy heat collection pipe, and respectively with air discharge duct in the vacuum-pumping system and the automatic control system that are connected, also be provided with air inlet in a side of air discharge duct; When inserting solar energy heat collection pipe, the thermal-collecting tube navigation system positions, and when being put into assigned address, sealing ring closely encases the glass outer tube of solar energy heat collection pipe, reaches sealing effectiveness.Automatic control system and cooling system setting are controlled the operation of whole unit with the PLC Programmable Logic Controller in position.
The exhaust flow path of described solar energy heat collection pipe exhaust equipment is: (a) the outer seal of tube exhaust of air discharge duct and solar energy heat collection pipe maintains the space between the inner tube of solar energy heat collection pipe and the outer tube of solar energy heat collection pipe, as the exhaust passage; (b) after exhaust finished, the propulsion plant in the air discharge duct advanced the inner tube of solar energy heat collection pipe, and it is contacted with the outer tube of solar energy heat collection pipe; (c) with the method for heating or welding make solar energy heat collection pipe inner and outer tubes welding; (d) take out solar energy heat collection pipe, exhaust finishes.
The mode of heating that described high-temperature heating equipment adopts can be any in flame heating, Resistant heating or the infrared heating mode.
The welding manner that described welder adopts can be a kind of in high-frequency welding, laser weld or the argon arc welding mode.
The interior cooling system that also is provided with for the condensation segment of cooling solar energy heat collection pipe at described air discharge duct.
The type of cooling that described cooling system is taked is any in air-cooled, water-cooled and the natural type of cooling.
This air discharge duct can be used for the exhaust of all-glass vacuum tube and hot pipe type vacuum heat collection pipe.When being used for the exhaust of all-glass vacuum thermal-collecting tube, the heater of air discharge duct outside is any in flame heating, Resistant heating or the infrared heating mode.The exhaust flow path of this moment is: air discharge duct and outer seal of tube exhaust, inner and outer tubes do not contact, as the exhaust passage, when glass tube is evacuated to certain vacuum, propulsion plant in the air discharge duct advances inner tube, it is contacted with outer glass pipe, then adopt any glass tube sealing by fusing that makes in flame heating, Resistant heating or the infrared heating mode to dock.
When being used for the exhaust of hot pipe type vacuum heat collection pipe, adopt the mode of welding that outer tube and inner tube are carried out sealing-in, this moment need to be on glass tube in advance weld metal can cut down, realize the glassy metal sealing-in, and then can cut down with heat pipe and weld, described welding manner can be a kind of in high-frequency welding, laser weld or the argon arc welding mode.
The present invention compared with prior art has following advantage:
(1) reduces the technique that connects tail pipe, improved production efficiency;
(2) do not have tail pipe, so that the security of product is improved, increase the service life;
(3) outward appearance of product improves, and is easy to apply.
When with this equipment solar vacuum heat-collecting pipe being carried out exhaust, do not need to weld in advance tailpipe, therefore can enhance productivity, reduce production costs, do not have simultaneously tail pipe can increase the aesthetic property of product.
