DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 6 A gas-liquid separation device for an atomic fluorescence spectrometer includes a main body 1, the main body 1 includes a fluid inlet 11, the fluid inlet 11 is located in the lower middle position of the side of the main body 1, and the liquid outlet 12 is located at the bottom of the main body 1. The main body 1 also includes a cleaning tank 13. A water inlet pipe 14 is provided at the upper end of the main body 1, and the inner wall of the water inlet pipe 14 is fixedly connected to the inner wall of the cleaning tank 13. A slot 15 is provided on the upper part of the main body 1, and a spiral groove 16 is provided on the inner wall of the main body 1. The air outlet at the upper end of the main body 1 is fixedly connected to a cleaning mechanism 2.

[0024] The cleaning mechanism 2 includes a mixing plug 20, and the mixing plug 20 includes a handle 201. The lower end of the handle 201 is fixedly connected to a circular plate 202. The lower surface of the circular plate 202 is fixedly connected to a piston tube 204. The upper side of the piston tube 204 is fixedly connected to an insert block 203. The side of the mixing plug 20 is movably plugged with a sealed bearing 21. The upper end of the sealed bearing 21 is provided with a slot adapted to the insert block 203. The side of the mixing plug 20 is movably plugged with a sealed bearing 21. The outer ring of the sealed bearing 21 is fixedly connected to the inner wall of the air outlet at the upper end of the body 1. The inner ring of the sealed bearing 21 A telescopic tube 22 is also fixed, and a guide plate 23 is spirally fixedly connected to the side of the telescopic tube 22, a cleaning brush 24 is fixedly connected to the bottom of the guide plate 23, and a cleaning cotton ball 25 is fixedly sleeved on the bottom of the telescopic tube 22; a clamping ring 221 is provided at the upper end of the connection of the telescopic tube 22, and a flange 222 is provided at the lower end of the connection of the telescopic tube 22, one side of the clamping ring 221 is slidably connected to the side of the telescopic tube 22, and one side of the flange 222 is slidably connected to the inner wall of the telescopic tube 22, an insertion strip 223 is provided on the side of the telescopic tube 22, and a long groove 224 is opened on the inner wall of the telescopic tube 22.

[0025] In this embodiment, the shell of the main body 1 is fixed with a pin that is compatible with the slot 15; specifically, the pin and the slot set on the shell of the main body 1 divided into two parts cooperate with each other, the two shells are fixedly plugged in, and waterproof sealant is applied between the two shells to reduce leakage of the main body 1 divided into two parts.

[0026] In this embodiment, through holes are spirally opened on the side and bottom of the telescopic tube 22 between the guide plates 23, and the side of the guide plate 23 is slidably connected to the inner wall of the spiral groove 16; specifically, the effect of the fluid in the main body 1 passing through the mixing plug 20 is increased, and at the same time, the liquid in the gas is liquefied when it touches the rod of the telescopic tube 22 and falls to the bottom of the main body 1 through the through holes at the bottom of the telescopic tube 22, and the spiral groove 16 provides a moving path for the guide plate 23 to move up and down inside the main body 1.

[0027] In this embodiment, the opening direction of the cleaning groove 13 is connected to the inner wall of the upper air outlet of the main body 1 at an inclined angle; specifically, the inclined cleaning groove 13 allows the cleaning liquid to flow down as close to the inner wall of the main body 1 as possible when entering, thereby improving the cleaning effect.

[0028] In this embodiment, the fluid inlet 11 is located on the side of the main body 1 below the telescopic tube 22 in a stationary state; specifically, when the fluid enters the main body 1 through the fluid inlet 11, the telescopic tube 22, the guide plate 23 and the mixing plug 20 located above the same horizontal plane as the fluid inlet respectively separate the fluid into gas and liquid, thereby further improving the cleaning effect.

[0029] In this embodiment, the cleaning brush 24 is in contact with the inner wall of the lower end of the main body 1; specifically, the cleaning brush 24 is in contact with the inner wall of the main body 1 and rotates to clean, and the inner wall of the main body 1 can be fully cleaned with the help of the cleaning liquid.

[0030] By setting a sealed bearing 21 connected to the inner wall of the air outlet at the upper end of the body 1, a cleaning brush 24 fixedly connected to the side of the spiral guide plate 23 fits the inner wall of the body 1, and the piston tube 204 is rotated by the handle 201, and the inner ring of the sealed bearing 21 is driven to rotate under the action of the plug block 203 and the slot at the upper end of the sealed bearing 21, thereby driving the telescopic tube 22, which is fixedly connected to the inner ring of the sealed bearing 21 and slidably connected to the inner wall of the spiral groove 16, to drive the inner ring of the sealed bearing 21 to rotate and drive the telescopic tube 22, and the telescopic tube 22 fixedly connected to the inner ring of the sealed bearing 21 is rotated. Under the control of the electrical signal, the bottom of the inner wall of the main body 1 is contacted, and at the same time, the cleaning brush 24 in contact with the inner wall of the main body 1 and the cleaning cotton ball 25 fixedly sleeved on the bottom of the telescopic tube 22 rotate together to clean the bottom of the inner wall of the main body 1. At the same time, the clean water source provided by the water inlet pipe 14 is sprayed obliquely toward the inner wall of the air outlet at the upper end of the main body 1 through the cleaning groove 13 to further clean the body. The guide plate 23 spirally fixedly connected to the side of the telescopic tube 22 provides a more effective contact area for gas-liquid separation of the fluid, and provides a more effective gas-liquid separation effect for the mixing plug 20.

[0031] How it works:

[0032] During use, the fluid enters the body 1. Due to the characteristics of the fluid itself, the fluid inside the body 1 rises. When it contacts the telescopic tube 22, the guide plate 23 and the mixing plug 20, the liquid molecules in the fluid are liquefied into droplets, which flow to the bottom of the body 1 through the surface of the telescopic tube 22, the surface of the guide plate 23 and the inner wall of the body 1. When the filtration is completed, it is only necessary to rotate the piston tube 224 through the handle 201 under the action of the slot at the upper end of the plug block 203 and the sealing bearing 21. The sealing bearing 21 drives the telescopic tube 22 to rotate. The telescopic tube 22 is assisted by the spiral groove 16 to fit close to the bottom of the body 1, and the external water pipe of the water inlet pipe is connected to the cleaning liquid. The cleaning liquid flows down along the inner wall of the body 1 through the inclined cleaning groove 13. During the descent of the telescopic tube 22, the cleaning brush 24 cleans the inner wall of the body.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
