Full-mechanical drive feeding device of reactor with high solid concentration

Abstract

The invention discloses a full-mechanical drive feeding device of a reactor with high solid concentration. The feeding device comprises a horizontal spiral conveyor, a longitudinal spiral conveyor, a longitudinal spiral feeder and a drum spiral conveyor, wherein the horizontal spiral conveyor is used for conveying materials horizontally; the longitudinal spiral conveyor is used for lifting the materials upwards; the longitudinal spiral feeder is used for feeding the materials into an anaerobic reactor; and the drum spiral conveyor is connected at the upper ends of the longitudinal spiral conveyor and the longitudinal spiral feeder. The feeding device avoids the following problems caused by sampling anaerobic fermentation materials with high solid concentration by utilizing hydraulic pressure and gravity: the liquid is more and the solid is less; the sampling quantity is not easy to control; pipelines are blocked; and valves are not easy to open, close or seal after being rusted.

Description

technical field [0001] The present invention relates to a feeding device, more specifically, the present invention relates to a fully mechanically driven feeder that is mainly used in anaerobic fermentation engineering and used in conjunction with high solid concentration (TS≥8%) anaerobic reactors. material device. Background technique [0002] Organic waste contains a large amount of organic matter, such as carbohydrates, proteins, fats, and cellulose. It is a biomass resource with a wide range of sources, large quantities, and high quality. To build large and medium-sized biogas projects——use anaerobic digestion technology to treat organic waste Material is an important means to promote the sustainable development of urban and rural economic construction and realize the dual benefits of energy and environmental protection. At present, more than 10% of organic solid waste in Europe is treated by anaerobic fermentation technology. [0003] The anaerobic reactor, including...

Problems solved by technology

However, when this method is applied in an anaerobic fermentation system with high solid concentration of TS≥8% or higher, it will have the following disadvantages: ①The collected liquid is too much and the solid is small, which cannot reflect the real composition of the sampling layer; ②Valves (commonly used are Butterfly valve and gate valve) are very easy to rust, which makes the operation more difficult, and even sampling is impossible, and the corroded valve is easy to cause poor sealing; ③The fluidity of high solid concentration materials in the pipeline is poor, and it is easy to form temporary retention and may block the pipeline ; ④ Difficult to control the sampling volume
