Problems solved by technology

Vacuum conveying systems usually contain the following problems in particular: high energy consumption, high air flow in the pipeline, noise in the outlet pipe, problems with dust and fine particles
Also, large systems require multiple separate make-up air valves, adding to system complexity and cost
Also, cleaning of the transfer line is important, so cleaning of the transfer system (often comprising multiple separate branch pipes) is cumbersome

Embodiment Construction

[0012] The drawings represent simplified material conveying systems, in particular waste conveying systems, using the method and device according to the invention.

[0013] exist figure 1 , reference numerals 61A, 61B, 61C denote supply stations for material to be conveyed, in particular waste material, from which station material to be conveyed, in particular waste material such as household waste, is to be supplied to the conveying system. The system may comprise a plurality of supply stations 61 from which the material to be conveyed is supplied to the conveying line 100 . Generally, the transfer pipeline includes a main transfer pipe 100, into which a plurality of branch transfer pipes can be connected, and a plurality of supply stations 61 can be connected to the main transfer pipe 100 through supply pipes. The supplied material is conveyed along the conveying line 100 to one or more separator devices 20 where the conveyed material can be separated from the conveying air...

Abstract

A method for sortingly conveying materials in a pneumatic material conveying system, such as a waste conveying system, in which method, material being conveyed is fed from at least one feed point and conveyed in a conveying pipe (100) by means of a pressure difference to a reception point in which the material is separated from conveying air in a separator device (20). In the method, different material sorts are fed from one or more feed points (61 A, 61 B, 61 C) at a time and conveyed to a reception site for at least a part of the conveying travel in the same conveying pipe and, in the method, at least a part of the conveying pipe (100) is cleaned between the conveying processes of different materials or at least when required.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 . [0002] The invention also relates to a device according to claim 14 . [0003] The present invention relates generally to pneumatic conveying systems, such as vacuum conveying systems, and in particular to collecting and conveying waste, such as conveying household waste. Background technique [0004] Systems are known in which waste is conveyed in pipes by suction. In these systems, waste is transported long distances in pipelines by suction. The device is particularly useful for conveying waste in different establishments. Usually, a vacuum device is used to obtain the pressure difference, in which vacuum device a negative pressure is provided in the transfer pipe by means of a vacuum generator, such as a vacuum pump or an ejector device. There is usually at least one valve element in the transfer pipe, the opening and closing of which valve element regulates the make-up a...
