Abstract
The invention discloses a lamp tube gas exhauster and particularly relates to a lamp tube gas exhauster which performs heating, vacuum pumping, inert gas flushing and inflating and lamp filament electrifying and decomposing on fluorescent lamp tubes. According to the lamp tube gas exhauster, ten-room vacuum pumps are used as lamp tube vacuum gas exhaust pumps. Ten output terminals of each ten-room vacuum pump correspond to ten sets of electromagnetic valve units and ten lamp tube sockets respectively. The ten-room vacuum pumps, the electromagnetic valve units and the lamp tube sockets are isolated mutually to form ten vacuum gas exhaust units which are not affected mutually. Influences on other lamp tubes due to gas leakage of a certain lamp tube are avoided. 2N ten-room vacuum pumps can be arranged in a linear mode to correspond to 2*10N electromagnetic valves and 2*10N lamp tube sockets to form 2*10N independent gas exhaust units. In order to reasonably utilize energy and improve the production rate of the lamp tubes, the 2N vacuum pumps and the corresponding lamp tube sockets are divided into two groups, one group is used for performing heating and gas exhaust, and the other group is separated and feeds tubes. The two groups are alternated to perform heating, vacuum pumping, inert gas flushing and inflating and lamp filament electrifying and decomposing work on the lamp tubes.
Description
Technical field
The present invention relates to a kind of lamp tube exhauster, be specifically related to the lamp tube exhauster to fluorescent tube is heated, vacuumizes, inert gas rinses inflation, the filament energising is decomposed.
Background technology
The air exhauster used at present be a vacuum pump logarithm only or tens fluorescent tubes vacuumize, the time of vacuum exhaust is longer, if there is a lamp tube air leaking will affect the exhaust quality of whole fluorescent tubes in exhaust process, cause fluorescent tube normally not start, when serious, can make all to be scrapped by the bank light pipe, so just increase the waste of electric power, increased the manufacturing cost of fluorescent tube.
Summary of the invention
The invention provides a kind of lamp tube exhauster, it is using ten Room vacuum pumps as fluorescent tube vacuum exhaust pump, respectively with ten groups of electromagnetic valve units of ten lead-out terminals of ten Room vacuum pumps, ten lamp tube socket correspondences; The vacuum exhaust unit that between ten Room vacuum pumps, electromagnetic valve unit and lamp tube socket, ten of separate formations are independent of each other, avoided due to the impact of certain lamp tube air leaking on other fluorescent tube.Can form and there is 2 * 10N independently exhaust unit by 2N platform ten Room vacuum pump corresponding 2 * 10N electromagnetically operated valve in one line, 2 * 10N lamp tube socket, productivity ratio for reasonable energy utilization raising fluorescent tube, 2N platform vacuum pump and corresponding lamp tube socket are divided into two groups, wherein during one group of thermal exhaust, an other component is from, upper pipe, two groups alternately to fluorescent tube heated, vacuumized, inert gas rinses inflation, filament energising apportioned effort.
The present invention realizes with following technical scheme: a lamp tube exhauster, comprise support, rack-mount electromagnetic valve unit, lamp tube socket, be distributed in two parallel tracks of socket front and back, be arranged on the baking oven that can move left and right on two tracks, being arranged on ground is baking oven 3, the control cubicle of ten Room vacuum pump 4 power supplies, be arranged in control cubicle is the PLC circuit of electromagnetic valve unit interruptedly supplying power, constant-current source for the filament interruptedly supplying power, cooling circulating water device for lamp tube socket water supply, the ten Room vacuum pumps for tube exhaust, for fluorescent tube provides the inert gas tank of purge gas, it is characterized in that: described ten Room vacuum pumps are ten independently vacuum pumps of high vacuum air chamber, and ten Room vacuum pumps are fixed on ground, the corresponding one group of electromagnetic valve unit of each lead-out terminal of ten Room vacuum pumps, a lamp tube socket, described lamp tube socket, electromagnetic valve unit divide and upper and lower two-layerly along the vertical word interval of support, arrange and be fixed on mid-stent, the electric comb that the promising fluorescent tube energising of each lamp tube socket edge distribution is decomposed, and electric comb is connected with constant-current source by wire, described support is rectangular frame structure, and the upper surface of support is equipped with the baking oven that can move left and right, described baking oven is the cuboid that cross section is the square type, and baking oven can be gas heating or electric heating, and baking oven is regulated the temperature inside the box by thermostat, described electromagnetic valve unit is by vacuum solenoid, form for fluorescent tube provides the duplex constant volume electromagnetically operated valve of purge gas, electromagnetic valve unit by PLC according to its working condition of tube exhaust technique initialization.
Good effect of the present invention
1. due to separate between each exhaust unit, be independent of each other, stopped to affect due to certain lamp tube air leaking other fluorescent tube quality.
2. utilize PLC that process route is set and can realize good exhaust air technique, make the exhaust quality of fluorescent tube high.
3. the pipeline of purge gas institute warp is short, and the inert gas utilance is high, has saved cost.
4. the evacuation time of fluorescent tube is short, is about 1/4 of existing lamp tube exhauster.
