Method and equipment for preparing mine repairing material from river sludge

Abstract

The invention discloses a method and equipment for preparing a mine repairing material from river sludge, and belongs to the technical field of sludge treatment. The equipment comprises a dehydrator, a mixing machine, a degradable film and a fixing plate. The dehydrator comprises a dehydration box body. The mixing machine comprises a material mixing barrel. A feeding hole is formed in the upper part of one side wall of the dehydration box body, and a first discharging hole in the lower part of the other side wall of the dehydration box body is communicated with the material mixing barrel through a material outlet channel. A discharging channel is arranged in the dehydration box body; a vertical material pressing channel is connected behind the discharging channel; a liftable pressing plate is arranged above the material pressing channel; a liftable filtering plate is arranged below the pressing plate; and a group of material pressing baffles are movably arranged above the filtering plate. A material adding hole is formed in the top of the material mixing barrel, and a second discharging hole is formed in one side wall of the material mixing barrel. A stirring roller is arranged in the material mixing barrel, a conical material mixing bottom plate is arranged below the stirring roller, and a material scraping part is arranged on the material mixing bottom plate in a sliding mode. The degradable film is laid on the surface of a mine slope. A pointed-end inserting rod is arranged at the bottom of the fixing plate.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a method and equipment for preparing mine restoration materials from river sludge. Background technique [0002] For a long time, lakes and rivers have been used as drainage and irrigation areas for industrial, agricultural and domestic sewage, resulting in the accumulation of pollution in rivers and lakes and serious eutrophication. However, the self-purification ability of rivers and lakes is poor, and the fluidity of lake water is small, which makes it difficult to treat the sediment of polluted rivers and lakes. In view of these problems, the commonly used treatment methods for river and lake sediment mainly include in-situ remediation and ex-situ remediation, among which the in-situ remediation technology is more widely used in the comprehensive treatment of biological agent remediation, in-situ covering of mud and ecological restoration; ex-situ remediation technol...

Problems solved by technology

At the same time, aiming at the dehydration process found in key links such as dehydration and mixing, the sludge contains hard impurities such as stones or metal impurities that cause damage to the equipment, and secondary pollution is prone to occur after dehydration, improving sludge and organic materials Secondary agglomeration is prone to occur after mixing, and each device is too scattered to cause a large space occupation. The present invention proposes targeted solutions to improve the efficiency and quality of processing.
