Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: the utility model provides a direct reading spectrum appearance shutter, including a light section of thick bamboo 1, be equipped with cylinder 2 on the light section of thick bamboo 1, be equipped with scarce groove 3 in the cylinder 2, be equipped with cylinder connecting rod 4 in the scarce groove 3, still be equipped with the drive circuit 5 that is used for controlling the action of cylinder 2 in the cylinder 2, be equipped with PLC controller 11 on the drive circuit 5, can input the accurate control that read-write data realized cylinder 2, light section of thick bamboo 1 is for controlling communicating structure, be equipped with breach 6 on the upper wall of light section of thick bamboo 1, the lower extreme of cylinder connecting rod 4 passes breach 6 and extends to in the light section of thick bamboo 1, and slide with breach 6 and link to each other.
An air pipe 7 for generating pressure difference by the cylinder 2 is arranged on the right side surface of the cylinder 2.
All be equipped with screw 8 on the both ends about cylinder 2, be equipped with bolt 9 on the screw 8, cylinder 2 passes through screw 8 and bolt 9 and links to each other with light section of thick bamboo 1 is fixed, fixes the position of cylinder 2.
And a sealing ring 10 is arranged on the contact surface of the connection part of the cylinder 2 and the light tube 1, so that the influence of air leakage on analysis data in the excitation process is prevented.
The center of the cylinder connecting rod 4 is overlapped with the center of the light tube 1, and the center of the light tube 1 can be shielded.
The working principle is as follows: the cylinder 2 is fixed on the processing surface of the light tube 1 by screws, the center of the cylinder connecting rod 4 is superposed with the center of the light tube 1, the connecting rod moves downwards when the cylinder connecting rod 4 needs to prevent the non-acting light from entering the rear section optical system under the control of the driving circuit 5, the light of the center part of the light tube 1 is blocked, and no light can enter the light chamber when the cylinder connecting rod 4 falls down because a slit is arranged in the corresponding optical system through the center of the light tube 1. When light generated by excitation needs to enter the light chamber, the cylinder connecting rod 4 is retracted, and the light normally enters the light chamber for data acquisition.
After adopting the shutter, the light that need not gather among the excitation process can not get into the light room, and the spectrum appearance excites the in-process, and general precombustion time accounts for about 50% or more of whole analysis time, through the implementation of this application, can effective control light pollution to the influence of analysis data stability. With the shutter case of practical implementation, the reproducibility index of the spectrometer can be improved by 50%, and meanwhile, the maintenance frequency of the spectrometer is reduced, the consumption of standard samples is reduced, and the workload of users is reduced. Factors influencing the analysis stability of the instrument are reduced through controlling the analysis process, so that the stability of the analysis data of the instrument is improved. Some entrance spectrometers have a shutter-like structure, such as ARL, Spectro.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
