Description

Rotary oscillation type nitrogen-blown sample pretreatment instrument Technical Field The utility model relates to the technical field of nitrogen blowing treatment, in particular to a rotary oscillation type nitrogen blowing sample pretreatment instrument. Background In many fields such as scientific research, chemical industry, medicine, etc., nitrogen-blown sample pretreatment is a common and key experimental operation link, and the aim is to realize concentration and drying of samples by nitrogen blowing, so that proper sample conditions are provided for subsequent experimental analysis. However, the conventional nitrogen-blown sample pretreatment apparatus has various drawbacks. On the one hand, in the nitrogen blowing process, the sample can only be passively purged by nitrogen, and the instrument lacks a synchronous mixing function. This makes the volatilization rate of each part of solvent in the sample inconsistent, and seriously affects the accuracy and repeatability of the experimental result. In order to achieve a uniform experimental effect, the staff has to spend additional time after nitrogen blowing, and perform secondary mixing operation on the sample by means such as manual shaking, using other mixing equipment, and the like. This undoubtedly increases the working steps, prolongs the overall pretreatment time, greatly reduces the working efficiency, and the errors introduced by manual operation further affect the reliability of the experiment. The inventor considers that the defects often exist that due to the lack of the synchronous mixing function, workers need to take additional time to carry out mixing operation on samples by adopting other means after nitrogen blowing, so that the problems of increasing the working steps and time cost and reducing the working efficiency are caused, and therefore, the rotary oscillation type nitrogen blowing sample pretreatment instrument is provided for solving the problems. Disclosure of utility model The utility model aims to solve the defects of increasing the working steps and time cost and reducing the working efficiency in the prior art, and provides a rotary oscillation type nitrogen-blown sample pretreatment instrument. In order to achieve the aim, the rotary oscillation type nitrogen blowing sample pretreatment instrument comprises a nitrogen blowing instrument, wherein the surface of the nitrogen blowing instrument is rotationally connected with a circular frame, the arc surface of the nitrogen blowing instrument is provided with an adjusting frame, the surface of the adjusting frame is provided with an adjuster, the arc surface of the adjuster is rotationally connected with a spraying frame, a plurality of spray heads are fixedly connected in the spraying frame, the arc surface of the spraying frame is provided with a rotating device, the rotating device comprises two L-shaped frames, the two L-shaped frames are fixedly connected with the arc surface of the spraying frame, the surface of the L-shaped frames is provided with grooves, the arc surface of the circular frame is fixedly connected with two fixing blocks, the fixing blocks are in sliding connection with the surface of the L-shaped frame, one side of each fixing block is fixedly connected with a fixing rod, the arc surface of each fixing rod is in sliding connection with an operation plate, one side of each operation plate is fixedly connected with an inserting rod, and the surface of the circular frame is provided with a plurality of test tube holes. The rotary device achieves the effect of simultaneously rotating the spray head and the circular frame, so that the effect of synchronously realizing sample mixing in the nitrogen blowing process and shortening the pretreatment time is achieved, the problem that the worker needs to use other means to uniformly mix the samples after nitrogen blowing due to lack of synchronous mixing function, the working steps and the time cost are increased, the working efficiency is reduced, and the practicability of the device is improved. Preferably, one end of the fixed rod, which is far away from the fixed block, is fixedly connected with a limiting plate, and the size of the inserted rod is matched with the size of the L-shaped frame slot. The limiting plate has the effect of limiting the maximum sliding distance of the operation plate on the arc surface of the fixed rod, and the situation that the operation plate is separated from the arc surface of the fixed rod due to overlarge pulling force when a worker pulls the operation plate is avoided. Preferably, the arc surface of the fixed rod is sleeved with a first spring, and two ends of the first spring are fixedly connected with the operation plate and the fixed block respectively. The first spring improves the stability of the inserted link when limiting the L-shaped frame. Preferably, the surface of the circular frame test tube hole is fixedly connected with a rubber ring, and the inner surfac
