Adjustable inclination self-cleaning vibrating trommel screen

Abstract

A self-cleaning vibrating drum screen with adjustable inclination, which mainly includes an outer scraper on the outer peripheral surface of the drum and upper and lower guards that contain the drum and have a small gap with the free end of the outer scraper. At the upper end of the shield support, the lower end of the shield support is fixed on the upper chassis of the chassis, and the upper chassis is connected with the lower chassis through hinges and two columns. The lower chassis is provided with two vertical hydraulic cylinders. The upper end of the hydraulic rod of the hydraulic cylinder is hinged with the upper chassis. A frame-shaped conveyor support is provided between the upper and lower undercarriages. The two friction rings at both ends of the trommel screen are set on two pairs of supporting wheels, and the two supporting wheel shafts on one side of the drum are respectively connected to the same reducer and speed-regulating motor through a coupling and a transmission shaft. scraper mechanism. The trommel screen of the present invention can perform vibration cleaning or vibration screening during the working process, and cooperate with the real-time cleaning of the inner and outer scrapers to keep the trommel screen in a clean state all the time, effectively prevent the sieve holes from being clogged, and have high screening efficiency.

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
