Plate type static-indeterminant combination bearing beam oversize vibration screen

Abstract

The model type super statically combined bearing beam large scale vibrating screen comprises screening plate, beam connection formed screening box, elastic support under the screening box, laser vibrator, motor and drive device on the motor base, model like super statically combined bearing beam inside the screening box, connecting with the screening box through high intensity hinging screw, output and inlet end of the screening box having rectangular closed beam connected with the combined bearing beam, and forming an enclosed big rigid container. It has increased structural rigidity, alleviated vibrating weight, improved efficiency, simplified structure, and simple processing. Due to its structural reliability, improved composite mechanical reliable life, it can meet extensive application in many industries.

Description

technical field [0001] The invention relates to a super-large vibrating screen with plate-type ultra-statically indeterminate combined load-bearing beams, which is especially suitable for grading, dehydrating, desliming and de-intermediation of coal particle size, and also suitable for grading, dehydration, de-sliming and de-intermediation of other materials. Background technique [0002] The vibrating screen is the main equipment of the coal preparation plant. It has many quantities, specifications and accidents. Especially the large vibrating screen is the key equipment for the new large-scale coal preparation plant and the technical transformation of the old plant in my country. Its reliability is directly related to the economic benefits of coal preparation plants. So far, there has been no major breakthrough in the structure and technology of large-scale vibrating screens, and the reliability and life of super-large vibrating screens cannot meet the actual needs of coal ...

Problems solved by technology

Its reliability is directly related to the economic benefits of coal preparation plants. So far, there has been no major breakthrough in the structure and technology of large-scale vibrating screens, and the reliability and life of super-large vibrating screens cannot meet the actual needs of coal mines and coal preparation plants.

The load-bearing beam of the traditional vibrating screen is designed as a single support carrier. If the width of the cross-section of the screen body exceeds 3 meters, the structural size and weight of the load-bearing beam will increase greatly. The corresponding vibration quality of the screen body will also increase.

As a result, the processing and assembly process of the load-bearing beam is difficult to guarantee, so that the failure of the tube beam and the side plate cracking often occurs during the use of the vibrating screen, which not only affects the production efficiency, but also seriously affects the service life of the screening machine. It is also the key factor that has long restricted the cross-sectional width of the vibrating screen body to increase and the structural parameters to break through

If the sieve cannot be made bigger, it can only meet the production needs by increasing the number of equipment, thus increasing the construction cost and production management cost
