Layered and extractable type high-prevision frequency adjustment vibrating screening machine

Abstract

The invention provides a layered and extractable type high-prevision frequency adjustment vibrating screening machine, and relates to the field of machinery. The layered and extractable type high-prevision frequency adjustment vibrating screening machine comprises a fixing base and a screening tool. A base plate is installed on the top of the fixing base, and the fixing base and the base plate areconnected through four supporting rods which are perpendicular to each other. A frame wall is fixedly connected with the top of the base plate, four fixing rods are further arranged on the top of thebase plate, and long U-shaped grooves are installed in the inner sides of the fixing rods. Screening basins are arranged on the tops of collecting basins, and mesh screen covers are installed on thetops of the screening basins. According to the layered and extractable type high-prevision frequency adjustment vibrating screening machine, a closed space is formed, the situation that the positionsof the mesh screen covers and the screening basins, the positions of the screening basins with different sizes, the positions of the screening basins and the collecting basins and the positions of thecollecting basins and the base plate are relatively stable is guaranteed, and therefore the whole screening tool is not prone to be dislocated, and materials cannot be spill from the screening tool;meanwhile, installation, disassembly and cleaning are easier; and the weight is automatically displayed by an electronic displayer, high-precision frequency adjustment is achieved, and the vibration efficiency of the different materials is improved.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a layered extractable high-precision frequency-modulated vibrating screen machine. Background technique [0002] The vibrating sieve machine is mainly used to replace the manual sieving and vibratingly sieves the particle size structure of granular and powdery materials. It is widely used in the scientific research and production of building materials, food, chemical industry, medicine, geology and other departments. The movement track of the material is divided into several grades through sieves with different sieve sizes. The types of vibrating sieves commonly used in the laboratory include slapping standard vibrating machines, top hitting standard vibrating sieves and standard inspection sieves. Wait. [0003] Notification number is the Chinese patent of CN209156381U, discloses a kind of vibrating screen machine, comprises vibrating base, sieve tool, pressing frame and positioning me...

AI Technical Summary

Problems solved by technology

When the above-mentioned vibrating screen machine takes out the sieve plate after vibrating the screen, it is necessary to loosen the pressure frame first, and then take out the screen basins with different sieve hole sizes layer by layer from top to bottom, which is extremely inconvenient to operate during installation and disassembly; After the completion, the quality of the materials screened by each layer of sieve basins cannot be directly known. It is necessary to use an electronic scale to weigh the quality of the materials in different sieve basins in turn. The vibration sieve is noisy and dusty
