Self-cleaning vibration drum screen with adjustable inclination angle

Abstract

A self-cleaning vibration drum screen with an adjustable inclination angle is mainly characterized in that an outer scraper as well as upper and lower protecting covers which cover the drum and have small gaps with a free end of the outer scraper are arranged on the peripheral surface of a drum, wherein the lower protecting cover is arranged at the upper end of a protecting cover bracket, the lower end of the protecting cover bracket is fixed on an upper underframe of an underframe, the upper underframe is connected with a lower underframe through a hinge and two upright columns, two vertical hydraulic cylinders are arranged on the lower underframe, and upper ends of hydraulic rods of the two hydraulic cylinders are hinged with the upper underframe; a frame-shaped conveyor bracket is arranged between the upper underframe and the lower underframe; two friction rings at two ends of the drum screen are arranged on two pairs of riding wheels, two riding wheel shafts on one side of the drum are connected with the same reducer and adjustable-speed motor through a coupling and a drive shaft respectively, and an inner scraper mechanism is arranged on the drum. According to the self-cleaning vibration drum screen, vibration cleaning or vibration screening can be performed in a working process of the drum screen, and the drum screen is further matched with real-time cleaning of an inner scraper and the outer scraper, so that the cleaning state of the drum screen can be maintained all along, screen holes are effectively prevented from being blocked, and the screening efficiency is high.

Description

technical field [0001] The invention relates to solid material separation and sorting equipment, in particular to a screening equipment for on-line treatment of garbage. Background technique [0002] With the development of cities and the acceleration of urbanization in rural areas, the output of garbage has increased rapidly, and some cities have faced the dilemma of being surrounded by garbage. Garbage mixed together is garbage, but separated is resources, so the classified collection and treatment of urban garbage has become a trend. Sorting equipment is the key equipment for garbage sorting. At present, the main sorting equipment is drum screen and vibrating screen. Through the screening of drum screens and vibrating screens, garbage of different specifications can be graded and regularized to achieve the purpose of classified treatment. However, there are still defects in the existing equipment: the drum screen can only turn the garbage material, and the vibrating scr...

AI Technical Summary

Problems solved by technology

However, there are still defects in the existing equipment: the drum screen can only turn the garbage material, and the vibrating screen can only vibrate the material. Due to this structural limitation, the screen is easy to attach small-sized or water-containing garbage, and the screen holes are easy to block. The screening capacity is small, the screening rate is low, and the garbage cannot be processed efficiently; the combination of drum screen and vibrating screen for sorting not only increases the process and costs, but also increases the space requirements for online garbage processing
