Conveying system and process for dry sludge dry material

Abstract

The invention relates to the technical field of sludge treatment, and specifically relates to a conveying system and process for a dry sludge dry material. The conveying system for the dry sludge material is a sludge conveying system embedded with a scraper conveyor, and comprises a lower horizontal section of the conveyor, a lower bent section of the conveyor, an upper bent section of the conveyor, a vertical section of the conveyor, an upper horizontal section of the conveyor, a power device, a material inlet, and a discharging device, wherein a scraper is located in a shell body of the conveyor; a rolling device is arranged on the bottom surface of the scraper; and buffer devices are arranged on the bottom surface and the two sides of the scraper. According to the conveying system and process for the dry sludge material, the problem that the scraper is abraded during conveying for the dry sludge material can be solved, the service life of the scraper is prolonged, and the efficiencyof conveying the dry sludge material is guaranteed.

Description

Technical field[0001]The invention relates to the technical field of sludge treatment, in particular to a sludge dry material conveying system and process.Background technique[0002]Disclosure of the background information is only intended to increase the understanding of the overall background of the present invention, and is not necessarily regarded as an acknowledgement or in any form suggesting that the information constitutes the prior art known to those of ordinary skill in the art.[0003]With the rapid development of industry and the continuous increase of urban population, the discharge of urban sewage has also increased unprecedentedly. The annual sewage treatment volume in my country is 53.75 billion cubic meters, and the output of dry sludge has reached 12.097 million tons, which is equivalent to dehydration with a moisture content of 80%. 60.48 million tons of sludge. The sludge produced in the sewage treatment process has a high water content, is bulky, is perishable, has...

Problems solved by technology

The problems existing in these methods are: the screw conveyor has the advantages of small cross-sectional area and good sealing performance. However, there is an upward transport process in the process of transporting the semi-dry sludge to the incinerator for incineration after being transported on the ground. The use of screw conveyor usually requires multi-stage transportation, which covers a large area and complex equipment; belt conveyor is an open transportation method, and the peculiar smell emitted by the sludge will pollute the surrounding environment

[0005] At present, the technology of using buried scraper conveyor to transport sludge has appeared in the existing technology, but due to the characteristics of semi-dry sludge, the scraper of the buried scraper conveyor is very easy to wear, and the gap between the scraper and the conveyor tank The friction between them is large, and a lot of power is consumed in the friction
