DETAILED DESCRIPTION

Embodiment 1

As shown in Fig. 1 to Fig. 3, a sodium thiosulfate suction filtration device proposed by the utility model comprises a working frame 1, a suction filter bottle 2, a filter bottle 3 and a filter membrane 7; the suction filter bottle 2 is arranged on the working frame 1; the filter bottle 3 is arranged on the suction filter bottle 2 and is detachably connected by threads; the filter membrane 7 is arranged on the suction filter bottle 2; and a filter assembly for filtering sodium thiosulfate is arranged on the working frame 1. The filter assembly comprises a stirring mechanism 4 rotatably arranged on the filter bottle 3, a vacuum assembly 5 arranged on the working frame 1, and a conveying mechanism 6 arranged on the working frame 1. An infusion tube 8 is arranged on the suction filter bottle 2. A control valve 9 is arranged on the infusion tube 8.

In this embodiment, when filtering the sodium thiosulfate stock solution, the other end of the input tube 602 is first connected to the sodium thiosulfate stock solution, and then the stirring mechanism 4, the vacuum component 5 and the conveying mechanism 6 are started; the conveying mechanism 6 conveys the stock solution to the filter bottle 3, replaces the docking of the suction filter bottle 2 and the filter bottle 3, reduces the number of clamping times of the suction filter bottle 2 and the filter bottle 3, thereby improving the filtering efficiency of the stock solution, and then the stock solution is separated into solution and solid particles under the blocking of the filter membrane 7, wherein the solution passes through the filter membrane 7 and enters the suction filter bottle 2, while the solid particles remain above the filter membrane 7. During the filtering process of the stock solution, the stirring mechanism stirs the stock solution, on the one hand, speeding up the filtering speed of the stock solution, and on the other hand, preventing the solid particles from staying on the filter membrane 7 and affecting the filtering efficiency; during the filtering process, the vacuum component 5 can adjust the pressure in the suction filter bottle 2, thereby speeding up the filtering speed of the stock solution and improving the efficiency. After the stock solution is filtered, the control valve 9 can be opened to allow the filtered solution to flow out from the infusion tube 8. When there are too many solids in the filter bottle 3 and the filter membrane 7 needs to be replaced, firstly one end of the output tube 603 is pulled out from the filter bottle 3, and then the filter bottle 3 is rotated to separate the filter bottle 3 from the suction filter bottle 2, after which the staff can clean the solid particles and replace the filter membrane 7.

The stirring blade 403 stirs the stock solution, which on the one hand accelerates the filtration rate of the stock solution, and on the other hand stirs the stock solution so that solid particles cannot accumulate on the filter membrane 7, thereby preventing the solid particles from affecting the filtration process.
