Description

Technical Field

[0001] The utility model relates to the technical field of flame photometers, in particular to a flame photometer. Background Art

[0002] A flame photometer is an analytical instrument based on the basic principle of emission spectroscopy. It uses flame as the excitation light source and applies a photoelectric detection system to measure the radiation intensity emitted when the excited element returns to the ground state from the excited state. The type of element and its content are determined based on its characteristic spectrum and light wave intensity.

[0003] A Chinese utility model with authorization announcement number CN218726661U discloses a flame photometer. When in use, the device filters toxic gases in the flue gas filtered by the filter through a filter and a purification net, thereby avoiding environmental pollution. However, the device has certain defects when used specifically. For example, when the filter absorbs toxic gases, the filtered particles will accumulate on the outer wall of the filter, gradually blocking the pores of the filter, reducing the filtration efficiency, and thus affecting the treatment effect of toxic gases and impurities in the flue gas. Therefore, it is necessary to redesign the flame photometer to address the above problems. Utility Model Content

[0022] The inner wall of the chimney 2 is fixedly connected to a limit rod 12, and a screw sleeve 13 is slidably connected to the outer wall of the limit rod 12. A device groove 3 is provided on the outer wall of the flame photometer body 1, and a fan blade 4 is rotatably connected in the device groove 3. A grid plate 5 is installed at the notch of the device groove 3. The inside of the device groove 3 and the outer wall of the chimney 2 are both rotatably connected to a transmission wheel 6, one group of which is coaxially fixedly connected to the fan blade 4, and the two groups of transmission wheels 6 are connected by a transmission belt. An incomplete gear 7 is rotatably connected to the outer wall of the chimney 2, and the incomplete gear 7 is coaxially fixedly connected to the transmission wheel 6.

The gear 8 is coaxially fixedly connected to the reciprocating screw 11. A smoke exhaust groove is provided at the upper end of the chimney 2, and is communicated with the inside of the chimney 2;

[0023] refer to Figure 2 and Figure 3 The fan blades 4 can improve the moisture-proof performance of the flame photometer body 1 as a whole, and when the fan blades 4 rotate, the reciprocating screw 11 can be synchronously driven to rotate, and the incomplete gears 7 and gears 8 form a group of speed reduction mechanisms, so as to avoid the fan blades 4 rotating too fast, which will cause the scraper 14 to slide too fast and cause aggravated wear.
