Double-group static-indeterminant mesh-beam exciting-vibration Plate type combination bearing beam oversize vibration screen

Abstract

A dual set super statically net beam laser vibrating model combined bearing beam big scale vibrating screen comprises screening box, elastic support under the screening box, super statically net beam device, motor and wheel tier type flexible articulator, model type horizontal rigid super statically combined bearing beam, several Y shape super statically combined reinforcing beam spaced on the side plate of the screening box, with the super statically net beam being dual super statically net beam laser vibrator that connects several net beams to the super statically connected plate and side plate forming into a beam combined container, the laser vibrator of the super statically net beam having 8 horizontally parallel arranged laser vibrating components and connected in series through universal joint, connecting with dual set super statically net beam forming an integral net beam big rigidity vibrator. It is simple in structure, fine in composite mechanical feature, good in structural process, reliable in vibrating stability with extensive application.

Description

technical field [0001] The invention relates to a super-large vibrating screen with double sets of ultra-statically determinate mesh beams to excite vibration plate-type combined load-bearing beams, especially suitable for grading, dehydration, desliming and deintermediation of coal particle size, and also suitable for grading, dehydration, desliming and desliming of other materials. Get rid of mediation. Background technique [0002] The vibrating screen is the main equipment of the coal preparation plant, which has many quantities, specifications and accidents, especially the large vibrating screen is the key equipment for the technical transformation of the old large coal preparation plant in my country. Its screening, dehydration, deintermediation process effect and reliability are directly related to the economic benefits of coal preparation plants. Due to technical reasons, domestic large-scale vibrating screens cannot meet the actual needs of coal mines and coal prepa...

Problems solved by technology

In this way, due to the limitation of material and mechanical processing technology level, the failure of pipe beam fracture and 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. The key factor that has restricted the cross-sectional width of the vibrating screen body from a long time ago is difficult to increase and the structural parameters are difficult to break through

The patent number is: ZL 02112809.x, which discloses the name "a large-scale vibrating screen with ultra-static fixed beam excitation", which solves the problem of the structural steel of the screen body with a width of more than 3 meters in the cross-section of the screen body and the large-scale vibrating screen The matching problem of the required exciting force, but when the width of the screen surface exceeds 3.6 meters, the overall structural stiffness of the screen body, the load-bearing beam structure and reliability problems are very prominent, which directly affects the reliability life of the vibrating screen and the working process effect , restricting the development of extra-large vibrating screens

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
