Description

Technical Field

[0001] The invention relates to the technical field of flame photometers, and in particular to a dust removal, heating and moisture removal device for flame photometers. Background Art

[0002] The flame photometer uses flame as an excitation light source to excite the atoms of the measured element, and uses a photoelectric detection system to measure the characteristic radiation intensity emitted by the excited element. The Model 410 produced by Sherwood is a single-channel, low-temperature flame photometer, which is used to measure the content of Na, K and Ca elements in the sample. The device has a safety device that will automatically shut down the gas pipeline when the flame is not ignited or the flame goes out during the measurement. There is also an air pressure valve. If the air pressure value is lower than a certain standard, the flame will not ignite or the flame will be extinguished. The pressure of the air source is 1kg / cm 2 (14psig), and must be clean and dry, with a flow rate of 6 liters per minute.

[0003] The existing technology mainly uses two types of air compressors, namely large air compressors and small air compressors. No matter what type of air compressor is used as the external air source, the 410 flame photometer will produce corresponding oil and condensed water according to the type of air compressor, and will also produce other impurities (such as rust particles, dust, etc.).

[0037] like Figure 1 and Figure 2A-2D As shown, an embodiment of the present invention provides a dust removal, heating and dehumidification device for a flame photometer, which includes: a dust removal and dehumidification box body 1, an observation cover 8 and a sealing cover 4, the dust removal and dehumidification box body 1 is connected to a heat conductor, the heat conductor includes a horizontal portion and a vertical portion, the side wall of the dust removal and dehumidification box body 1 is connected to the combustion furnace wall of the flame photometer through the vertical portion, the bottom of the dust removal and dehumidification box body 1 is connected to the horizontal portion, the dust removal and dehumidification box body 1 includes a dehumidification box 10 and a dust removal box 11 arranged in sequence, the side wall of the dehumidification box 10 is connected to the vertical portion, the front of the dust removal box 11 is provided with a first opening, the sealing cover 4 is arranged at the first opening and matches the first opening, the front and upper surface of the dehumidification box 10 are provided with a second opening, the observation cover 8 is arranged at the second opening, matches the second opening, and is detachably connected to the dehumidification box 10.

[0038] The side wall of the dehumidification box 10 is provided with a dehumidification box air inlet 14 , so that the dehumidification box 10 is connected to the heat conduction air outlet of the heat conductor through the dehumidification box air inlet 14 .

[0039] Furthermore, a dust removal box air outlet 15 is provided on the back side of the dust removal box 11 , so that the dust removal box 11 is connected to the air inlet joint of the flame photometer through the dust removal box air outlet 15 .

[0040] Furthermore, the dehumidification box 10 and the observation cover 8 are arranged to form a receiving chamber for receiving the dehumidifier 12, and a dehumidifier is arranged inside the dehumidifier 12. Figure 2B As shown, the dehumidifier 12 includes a turbine 13, a dehumidifier isolation net, a stirring shaft 5 and a connecting end cover 3, wherein the number of the dehumidifier isolation nets is two, which are respectively arranged on both sides of the stirring shaft 5, the turbine 13 is connected to the air inlet 14 of the dehumidifier box, and the connecting end cover 3 is connected to the dust removal box 11. After the compressed air enters the dehumidifier box through the heat conductor, the wind speed of the compressed air is used to drive the turbine 13 to rotate, and then the stirring shaft 5 is driven to rotate through the turbine 13 to turn over the dehumidifier in the dehumidifier 12, thereby improving the moisture absorption uniformity of the dehumidifier; at the same time, the bottom of the dehumidifier box 10 can conduct the heat of the combustion furnace wall of the flame photometer through the heat conductor, so that the heat conducted to the bottom of the dehumidifier box 10 can be used to heat and evaporate the moisture absorbed by the dehumidifier to increase the service life of the dehumidifier. As an example but not a limitation, the dehumidifier is silicon dioxide. The function of the stirring shaft 5 is, on the one hand, to stir the dehumidifier to better absorb moisture, and on the other hand, to stir the dehumidifier so that the dehumidifier contacts the bottom of the dehumidifier box 10 for heating and dehumidification, thereby increasing the service life of the dehumidifier.

Since the vertical part of the heat conductor is connected to the combustion furnace wall of the flame photometer, and the heat conductor is respectively connected to the dehumidification box 10 and the dust removal box 11, the heat conductor will take away the heat of the furnace wall by using the principle of heat conduction, and preheat the air in the dehumidification box 10 and the dust removal box 11 respectively, so as to increase the intake temperature of the flame photometer, on the one hand, improve the ignition rate, on the other hand, reduce condensed water, and at the same time reduce gas energy consumption. At the same time, since the observation cover plate 8 is detachably connected to the dehumidification box 10, it is convenient to observe the color change of the dehumidification agent, whether it is agglomerated, etc., so as to know the dehumidification effect of the dehumidification box 10.
