Description

An automatic liquid discharge structure for an atomic fluorescence spectrometer Technical Field

[0001] This utility model relates to the field of liquid drainage technology for atomic fluorescence spectrometers, specifically to an automatic liquid drainage structure for atomic fluorescence spectrometers. Background Technology

[0002] An atomic fluorescence spectrometer is an instrument used to detect and analyze atomic fluorescence. It determines the content of the analyte by measuring the fluorescence emission intensity produced by the atomic vapor of the analyte under the excitation of radiation energy. When using an atomic fluorescence spectrometer, a lot of waste liquid is generated. The automatic liquid drainage structure of the atomic fluorescence spectrometer is a system used to deal with the waste liquid generated by the instrument during the analysis process.

[0003] The existing patent with authorization announcement number "CN218601160U" discloses an automatic liquid discharge device for an atomic fluorescence spectrometer, including a device body. A reaction chamber is set at the left end of the device body, and a liquid discharge chamber is set at the right end. A water pump is set at the lower end of the reaction chamber, a water pump pipe is set at the upper end of the water pump, and a water outlet pipe is set at the right end of the water pump. A filter plate is snapped into the inside of the liquid discharge chamber. The automatic liquid discharge device for atomic fluorescence spectrometer has a detachable filter plate set at the upper end of the inside of the liquid discharge chamber. It can not only filter the waste liquid discharged from the reaction chamber, but also remove the filter plate to clean the filter screen and impurities inside. The device body also has a purification box set at the lower end of the inside of the liquid discharge chamber. The purification agent in the purification box is filled with a mesh bag for easy removal and replacement. The purification agent can purify the waste liquid, thereby ensuring that the discharged waste liquid is free of impurities and toxicity, will not pollute the environment, and is easy to use.

[0004] However, this device has the following shortcomings:

[0005] 1. When the photometer discharges liquid, the discharged liquid needs to be filtered. Because there are many impurities in the discharged liquid, the filter screen will often be clogged. However, the above-mentioned device is difficult to automatically remind the staff when the filter screen is clogged, which makes it difficult for the staff to detect the filter screen clogging in time, thus affecting the use of the photometer.

[0006] 2. When the filter screen is clogged, the above-mentioned device cannot automatically backwash the filter screen, which means that the filter screen still needs to be removed and cleaned. This not only reduces the convenience of cleaning, but also affects the service life of the filter screen. Summary of the Invention

[0030] The backwash assembly 5 includes a motor 51, a rotating rod 52, a U-shaped connecting rod 53, a hinged rod 54, a push rod 55, a blockage block 56, a water pump B57, and a backwash pipe 58. The motor 51 is located at the top of the drain chamber 31. The output end of the motor 51 is equipped with a rotating rod 52. Two sets of U-shaped connecting rods 53 are installed on the rotating rod 52. The outer side of the U-shaped connecting rods 53 is fitted with a hinged rod 54. The top and bottom of one side of the partition 32 are fitted with push rods 55 that are hinged to the two sets of hinged rods 54. The top of the filter screen 24 and the bottom of the purification box 25 are both equipped with guide blocks. The two sets of push rods The push rod 55 is fitted inside the guide block and can slide along the inside of the guide block when the push rod 55 moves, which improves the stability of the movement. The outer side and one side of both sets of push rods 55 are equipped with a blocking block 56. The blocking block 56 is shaped like a frustum and has a good sealing effect to prevent water leakage. A water pump B57 is installed at the bottom of the filter chamber 1. The output end of the backwash pipe 58 is connected to the backwash pipe 58 connected to the filter chamber 1. The input end of the water pump B57 is connected to the backwash water source, which can perform backwashing when the filter screen 24 is clogged, improving the convenience of cleaning.

[0031] Working principle: When the atomic fluorescence spectrophotometer is draining, the water pump A21 can be started to extract the waste liquid in the spectrophotometer. The waste liquid can be transported to the filter chamber 1 through the guide pipe 22 and the delivery pipe 23. The impurities in the waste liquid can be filtered through the filter screen 24. The filtered waste liquid can be purified through the purification box 25. The purified waste liquid can then enter the drain chamber 31 through a set of guide holes 34 at the bottom, and then be discharged outward through the drain pipe 33.

[0032] When the filter screen 24 is clogged with impurities, the waste liquid drainage efficiency is slow, and the water pressure at the top of the filter screen 24 gradually increases. At this time, the water pressure can be used to push the piston 44 to overcome the elastic force of the spring 45 and move upward. When the guide rod 43 pushes the electric contact A46 to contact the electric contact B47, the indicator light 48 can be automatically activated. The indicator light 48 makes it easy for the staff to keep abreast of the device blockage and to clean the filter screen in a timely manner.

[0033] When the filter screen becomes clogged, the operator can activate motor 51 and water pump B57 for backwashing. Sleeve 41 drives rotating rod 52 to rotate 180 degrees. After rotation, the top set of push rods 55 moves to the left, while the bottom set moves to the right. The top set of push rods 55 blocks the delivery pipe 23 with the top blockage block 56, simultaneously opening the top set of guide holes 34. The bottom set of push rods 55 then drives the blockage block 56 to open the backwash pipe 58, blocking the bottom set of guide holes 34. Water pump B57 then extracts the backwash liquid, which flows through backwash pipe 58 into filter chamber 1 to backwash the purification box 25 and filter screen 24. The backwash water carries impurities through guide holes 34 into drainage chamber 31, and then is discharged through drainage pipe 33, improving the ease of cleaning filter screen 24.

[0034] After backwashing the filter screen 24, the motor 51 controls the rotating rod 52 to rotate 180 degrees, and the interface drives the two sets of push rods 55 to reset, so that the liquid drainage process can be carried out normally.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
