Description

The gaseous discharge lamp pilulae hydrargyri

The utility model relates to a kind of device that is used for producing in the gaseous discharge lamp mercury vapour.

As everyone knows, gaseous discharge lamp is lighted fluorescent tube itself must possess three conditions, and the one, the tube inner impurity gas partial pressure is enough low, and the 2nd, the mercury vapour of q.s is arranged, the 3rd, quantitative inert gas is arranged.Present all kinds of gaseous discharge lamp, when producing as fluorescent lamp, electricity-saving lamp, annular lamp, neon light etc., the mercury vapour in its fluorescent tube all adopts " dripping mercury " technology to add, and is about to liquid mercury and splashes in the fluorescent tube, at high temperature vacuumizes then and encapsulates.This technology is more backward, environmental pollution is very big, because of most liquid mercury flows in the room atmosphere in high-temperature exhaust air (vacuum) process, very harmful to human body, the occupation patient of manufacturer increases year by year, and consume a large amount of liquid mercury consumptions and environmental protection facility expense, product quality also is difficult to control.

In addition, once there was a kind of snap ring-type pilulae hydrargyri to appear on the market, but it is had relatively high expectations to the location reducing of fluorescent tube blast pipe, otherwise fixing pilulae hydrargyri, this is difficult to promote in the many producers of China, and uses on the multistation air exhauster that it can only vacuumize in the bottom, heat in top, can't on common mercury formula multistation air exhauster, use (the most common multistation air exhauster of China is the top exhaust, heat in the below), so existing snap ring-type pilulae hydrargyri operating procedure complexity requires height, is difficult to penetration and promotion.

The purpose of this utility model is exactly in order to address the above problem, provide a kind of can contaminated solution, reduce mercury consumption and expenses of environmental protection and be convenient to the gaseous discharge lamp pilulae hydrargyri of extensive penetration and promotion.

Technical solution of the present utility model:

A kind of gaseous discharge lamp pilulae hydrargyri, it is characterized in that it is made up of the thin-walled cavity body of centre and the sheet sealing-in body at two ends, they are an integral body, be marked with liquid mercury in thin-walled cavity body in the middle of it, the maximum overall dimension of middle thin-walled cavity body and two ends sheet sealing-in body thereof should be less than the internal diameter of the fluorescent tube blast pipe of gaseous discharge lamp greater than the bore of reducing in this blast pipe.

The utility model is when the process gas discharge lamp, can eliminate mercury vapour pollutes, saved expenses of environmental protection, and can accurately guarantee the mercury amount, help improving the fluorescent tube quality, reduce cost, improve qualification rate, the utility model adopts the pure nickel pipe manufacturer, special sealing-in, be fit to the secondary process for sealing, it is fixed and freely makes things convenient for, and reducing does not have specific (special) requirements to blast pipe, its liquid mercury purity is 99.9999, its can mercury amount can supply different demands, is generally 3 milligrams-12 milligrams, is fit to general discharge lamp manufacturing enterprise large-scale production demand.The utility model operating procedure is simple, is convenient on common multistation air exhauster, use, but the large tracts of land penetration and promotion.

The utility model is described in further detail below with reference to accompanying drawing.

Fig. 1 is the schematic diagram of a kind of structure of the present utility model;

Fig. 2 is the end view of Fig. 1;

Fig. 3 is the schematic diagram of another kind of structure of the present utility model;

Fig. 4 is the end view of Fig. 3;

Fig. 5 is the utility model actual schematic diagram of laying in process of production.

As Fig. 1-4, the utility model is made up of the thin-walled cavity body 1 of centre and the sheet sealing-in body 2 at two ends, they are an integral body, be marked with liquid mercury in thin-walled cavity body in the middle of it, the maximum overall dimension of middle thin-walled cavity body 1 and two ends sheet sealing-in body 2 thereof should be less than the internal diameter of the fluorescent tube blast pipe of gaseous discharge lamp greater than the bore of reducing in this blast pipe.

In the utility model, middle thin-walled cavity body 1 and two ends sheet sealing-in body 2 thereof can adopt metal materials such as iron, nickel or alloy material to make.The sheet sealing-in body 2 at two ends can be straight sheet (seeing Fig. 1,2), also bending (seeing Fig. 3,4), and sheet sealing-in body 2 temperature tolerances of its bending are better, can reach 450 ℃.

During the utility model work, pilulae hydrargyri of the present utility model is placed in the blast pipe 5 of band reducing 4 of processed fluorescent tube 3, see Fig. 5 (among Fig. 5 be example with U type power saving fluorescent lamps), because the overall dimension of pilulae hydrargyri is greater than reducing 4 bores, then it just is stuck in reducing 4 tops of blast pipe 5, can not drop in the fluorescent tube 3, then this blast pipe 5 be sealed in advance.Can be placed into like this on the common multistation air exhauster and enter deairing step,, all can be suitable for no matter be upward exhaust or exhaust multistation air exhauster down.After the exhaust, enter the high-frequency heating operation, temperature is up to about 800 ℃, becoming mercury vapour after the liquid explosion in the middle of making in the thin-walled cavity body 1 enters in the processed fluorescent tube 3, finish and fill the mercury operation, carry out the secondary sealing-in at last, and remaining housing after blast pipe 5 and the interior pilulae hydrargyri explosion thereof is together removed, just make desired fluorescent tube.

Claims (2)

1, a kind of gaseous discharge lamp pilulae hydrargyri, it is characterized in that it is made up of the thin-walled cavity body of centre and the sheet sealing-in body at two ends, they are an integral body, be marked with liquid mercury in thin-walled cavity body in the middle of it, the maximum overall dimension of middle thin-walled cavity body and two ends sheet sealing-in body thereof should be less than the internal diameter of the fluorescent tube blast pipe of gaseous discharge lamp greater than the bore of reducing in this blast pipe.

2, gaseous discharge lamp pilulae hydrargyri according to claim 1, it is characterized in that described in the middle of the sheet sealing-in body at thin-walled cavity body two ends can be straight sheet, also bending.
