Scattered material return device for conveyor

Abstract

The invention discloses a material spilling return device for a conveyor, which is installed under an inclined conveyor belt and includes a lower return wheel rotatably installed under the lower end of the conveyor belt, and an upper return wheel is rotatably installed under the upper end of the conveyor belt wheel, a loopback conveyor belt is connected between the upper loopback wheel and the lower loopback wheel, and a belt tensioning device is provided between the upper loopback wheel and the lower loopback wheel; the loopback conveyor belt is located on the upper The return wheel is provided with a material cleaning device; the present invention is arranged under the conveyor belt, and the residue spilled on the conveyor belt is re-transported back, and when it is returned to the feeding hopper, it is cleaned once with a brush, so that the elutriating conveyor conveys It is more thorough and effectively prevents the material from spilling; the return conveyor belt is more stable through the tensioning of multiple conveyor belts.

Description

technical field [0001] The invention relates to the technical field of material transportation, in particular to a material return device. Background technique [0002] According to the patent with the application number "201110075603.4" and the invention name "Municipal Domestic Garbage Resource Classification and Utilization Method", the municipal domestic garbage can be processed by magnetic separation, garbage cutting, elutriation and flotation, garbage cleaning, and garbage extrusion. Dehydration steps, anaerobic treatment steps, and sludge sedimentation and concentration steps are used to realize resourceful treatment; the elutriation and flotation steps use garbage elutriation sorting machines, and the raw materials of garbage elutriation sorting machines are provided by elutriation conveyors ( like Image 6 shown) to the feed hopper of the garbage elutriation and sorting machine, there is a gap between the discharge end of the currently used elutriation conveyor and ...

Dehydration steps, anaerobic treatment steps, and sludge sedimentation and concentration steps are used to realize resourceful treatment; the elutriation and flotation steps use garbage elutriation sorting machines, and the raw materials of garbage elutriation sorting machines are provided by elutriation conveyors ( like Image 6 shown) to the feed hopper of the garbage elutriation and sorting machine, there is a gap between the discharge end of the currently used elutriation conveyor and the feed hopper of the garbage elutriation and sorting machine, so in the actual work process The raw materials on the elutriation conveyor often have residues when they pass through the discharge end, such as sediment and film stuck by a small amount of water, and these residues will be spilled when the conveyor belt of the elutriation conveyor goes back and forth. , which makes the transportation of garbage raw materials incomplete, and it is easy to accumulate garbage under the washing conveyor. Of course, the cleaning of accumulated garbage will consume manpower and material resources
