Description

Technical Field

[0001] The utility model relates to the technical field of filtering and washing equipment, in particular to a filtering and washing device for preparing organic compounds. Background Art

[0002] Organic compounds are compounds composed of carbon and hydrogen and some other atoms (such as oxygen, nitrogen, sulfur, etc.). There are many types of organic compounds. They can be synthesized from simple molecules through organic synthesis methods, or they can be synthesized through biosynthesis or exist naturally. Their properties and structures determine their applications in chemistry, biology, etc.

[0003] In the preparation of organic compounds, washing and filtration are key process steps. Washing is used to remove impurities or unreacted substances produced by the reaction, while filtration is used to separate precipitates or solid products.

[0004] For washing, a suitable solvent is usually selected to wash the product to remove impurities therein. The washing can be repeated until the purity of the resulting solution meets the requirements. During the washing process, one or more different detergents can be used, or extraction can be performed to achieve a more thorough washing effect.

[0005] During the filtration process, the solid product is separated from the solvent through a filtration device. Through filtration, a clean solid product can be obtained to meet the requirements of further processing or analysis.

[0006] When preparing specific organic compounds, correct washing and filtration processes are important steps to ensure product purity and quality.

[0007] In view of the above problems, it is urgent to carry out innovative design based on the original filtering and washing device. Utility Model Content

[0008] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a filtering and washing device for preparing organic compounds with a solution that is significantly different from the existing technology, so as to solve the problems raised in the above background technology.

The main shaft is located in the top area of ​​the shell and is equipped with a full gear set, and the full gear set is connected to an auxiliary shaft. The lower end of each auxiliary shaft passes through the top of the shell and is connected to a stirring blade.

[0011] Preferably, the filtering and separation structure includes a partitioned filter plate, an opening plate, a control shaft, a notched disk, a clamping rod, and a reset spring. The partitioned filter plate is installed in the shell, and the opening plate is attached to the top of the partitioned filter plate. The bottom of the opening plate is rotatably connected to the control shaft, and the lower end of the control shaft passes through the partitioned filter plate and the bottom of the shell. The control shaft is located in the outer area of ​​the bottom of the shell and is connected to the notched disk, and a clamping rod is clamped on the side of the notched disk. The end of the clamping rod is rotatably connected to the bottom of the shell, and a reset spring is connected to the outer wall of the clamping rod and the bottom of the shell.

[0012] Preferably, one half of the partitioned filter plate is provided with a plurality of fan-shaped mesh areas of the same area, and the mesh diameter of each fan-shaped mesh area increases successively, and the fan-shaped mesh area on the other half of the partitioned filter plate is arranged symmetrically opposite thereto.

[0013] Preferably, a fan-shaped opening is provided on each of two symmetrical sides of the opening plate, and the size of the opening is the same as the size of the fan-shaped mesh area on the partition filter plate.

[0014] Preferably, a plurality of notches are provided on the side of the notch disk corresponding to the number of the fan-shaped mesh areas, the clamping rod is arranged in an "L"-shaped structure, and the end of the clamping rod is engaged with the notch on the notch disk.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows: the filtering and washing device for preparing organic compounds, through the design of the servo motor, scraper rod, stirring structure and spray plate, enables the device to spray a suitable solvent more evenly on the product through the spray plate, and the stirring of the stirring structure allows the product and the solvent to have a more sufficient contact reaction, thereby effectively removing impurities therein, and the design of the scraper rod prevents the product from adhering to the inner wall of the shell, which is not conducive to washing and stirring and mixing.

[0016] Through the design of the filtering and separation structure, the device can separate solid particles or crystals of different sizes through the meshes of different aperture sizes on the partitioned filter plate and the switching of the opening plate, thereby obtaining the desired product with higher purity. This filtering method can effectively remove fine impurities in the product and improve the purity and quality of the product. At the same time, after screening and filtering the solid precipitate in the solution, the desired pure product can be separated more thoroughly, meeting the requirements of subsequent processing and analysis. This filtering method is crucial to the preparation process of organic compounds and provides a key guarantee for the accuracy of subsequent processes and experimental results.
