Belt type screening and conveying device for vibrating screen

Abstract

The invention relates to a belt type screening and conveying device for a vibrating screen. The belt type screening and conveying device is fixedly arranged on a screen box of the vibrating screen, and is characterized by comprising driving rollers, driven rollers, a plurality of upper carrier roller components, a plurality of lower carrier roller components and a plurality of screening belts; roller shafts at the two ends of the driven rollers are fixed to a side plate at the discharging end of the screen box of the vibrating screen, roller shafts at the two ends of the driving roller are fixed to a side plate at the feeding end of the screen box of the vibrating screen, the driving rollers and the driven rollers are sleeved with the plurality of screening belts, and each ascending screening belt is erected on a spacer bush of the corresponding upper carrier roller component; and the descending screening belts are respectively and alternately erected on upper-mounted lower carrier rollers and lower-mounted lower carrier rollers, so that a gap between every two screening belts erected on the lower carrier roller components is larger than a gap between every two screening belts erected on the upper carrier roller components. The vibrating screen has the advantages that holes are not blocked, the screening efficiency is high, the throughput can be independently controlled, the vibration quality of the vibrating screen is reduced, and the overall service life of the vibrating screen is prolonged.

Description

Technical field[0001]The present invention belongs to the field of vibration screening techniques, and more particularly to a belt screen conveying device for a vibrating screen.Background technique[0002]The vibrating screen is a screening apparatus for sieving coal, coke, ore, and other materials such as electricity, metallurgy, chemical, building materials, coal mine and other industries. The vibrating screen for material particle size grading is mainly circular sport screen and linear screen, vibration The screening surface of the sieve is composed of a screening plate desired by the screening material, but there are still many problems to be solved during the optimization process.[0003]First, plugging probability[0004]The probability of the plug is the most important performance indicator of the vibrating screen. If the probability of the plug is high, it means that the screen is quickly blocked by the critical hole size particle size, resulting in the screening surface, so the ...

[0013] 3. Sieve surface inclination

[0021] When the existing vibrating screen sieves materials, the movement of the materials on the screen surface is due to sliding friction, and the sieve plate wears quickly and needs to be replaced frequently. The use and maintenance costs of the vibrating screen sieve plate are the main costs of the vibrating screen operation
