Description

Technical Field

[0001] The utility model relates to the technical field of suction filtration, in particular to a suction filtration bottle with an ultrasonic box device and an automatic membrane changing mechanism. Background Art

[0002] At present, during the filtration process, the conventional filtration device will be blocked by the precipitation of the precipitate in the early stage of the experiment due to the large amount of precipitation of some powders with smaller ions, while the solution has not been filtered yet. In addition, the sample will be stratified due to the long filtration time, resulting in low filtration efficiency, uneven mixing, and precipitation loss. The accuracy of the experiment is affected while wasting experimental time. In addition, due to the limitation of constantly changing the filter membrane in the filtration bottle during the experiment, the experimental accuracy is affected and the experimental efficiency is also reduced. The filtration bottles of the prior art do not have ultrasonic devices, which makes it impossible to carry out these powders with smaller particles in the traditional filtration bottles. At the same time, the traditional filtration bottles are not convenient for changing the filter membrane. Therefore, technical improvements are urgently needed. Therefore, those skilled in the art provide a laboratory filtration bottle with an ultrasonic device and automatic membrane replacement to solve the problems raised in the above background technology.

[0003] A Chinese patent discloses a novel suction filtration device (authorization announcement number CN220736494U, the patented technology includes a suction filter box, a filter layer plate that can be pulled out from the front side is arranged in the suction filter box, the cross-sectional shape of the filter layer plate is a stair step shape that decreases layer by layer from left to right, a liquid inlet is arranged at the top left side of the suction filter box, a liquid outlet is arranged at one side of the bottom of the suction filter box, a scraper is arranged in the suction filter box through a movable driving member, and the bottom of the scraper is in contact with the filter layer plate: by setting the filter layer plate to the shape of a stair step, firstly, the surface area of ​​the filter layer plate can be greatly increased, and the filtration efficiency can be improved; secondly, when the mother liquid raw material is removed from the filter, the mother liquid raw material is removed from the filter. As the layers flow from left to right, the powders deposited on the filter plates will be continuously washed to the right side of the filter box, reducing the blockage of powders on the left filter plates and ensuring smooth downward flow of the mother liquor. Third, the vertical section of the stair step shape is not easy to accumulate powders, thereby maintaining the smoothness of the mother liquor in this section and improving the overall filtration efficiency. The patent describes the use of step-by-step filtration to increase the filtration rate, but it cannot guarantee the uniformity of the sample, and manual operation is required in the replacement of the filter membrane, which is not simple enough and prone to manual errors.

[0004] A Chinese patent discloses a porous suction filtration device with an automatic stirring device (authorization announcement number CN220758295U), which includes a sample cup and a suction filtration mechanism, a magnetic stirring mechanism is arranged at the bottom of the sample cup, a magnet is arranged at the bottom of the sample cup, and a main shaft fixed to the magnet is rotatably installed through a connecting part, and the main shaft is connected with at least one rotating star along the height direction, and the rotating star includes a sleeve sleeved outside the main shaft, and the sleeve is fixed to the inner wall of the sample cup through a supporting rod perpendicular to the main shaft, and a fixed bevel gear with the center penetrated by the main shaft is fixed at the upper end of the sleeve, and also includes a fixed sleeve fixedly sleeved on the main shaft and located above the fixed bevel gear, and the peripheral surface of the fixed sleeve is provided with at least one connecting rod perpendicular to the main shaft, and the end of the connecting rod is rotatably connected with a rotating bevel gear meshing with the fixed bevel gear, and the center of the rotating bevel gear is connected to the stirring body through a fixed rod. The utility model can make the suction filtration solution uniform through magnetic automatic stirring, and the magnet cooperates with multiple rotating stars to stir, so that the stirring is more sufficient. The patent describes the use of porous stirring to increase the filtration rate, but too many filtration holes will cause a large amount of sample loss, and the replacement of the filter membrane is not automated and is not simple enough.
