Unblocking device for cylindrical flat-bottom-shaped reinforced concretebunker

Abstract

The invention discloses an unblocking device for a cylindrical flat-bottom-shaped reinforced concretebunker and belongs to an auxiliary device for mineral separation. The unblocking device is characterized by comprising an air compressor, manual ball valves I, II and III, air storage tanks I and II, manual ball valves, left and right distribution boxes, an electric control cabinet, a pneumaticflow-assisting device and a pneumatic control device, wherein an auxiliary bunker is mounted at the flat bottom of the bunker; discharging hoppers are mounted on the bottom surface of the flat bottom of the bunker; the pneumatic control device mainly comprises a master control pipeline, an FRL combination (namely, the combination of an air filter, a pressure reducing valve and an atomized lubricator), a two-position two-waysolenoid valve, a pressure gauge II, acircular control pipeline, main control pipelines I and II, a branch control pipeline and pneumaticactuators I; the pneumaticflow-assisting device mainly comprises a master flow-assistingpipeline, a non-return valve, a pneumatic ball valve, a pneumaticactuator II, a pressure gauge I, a circular flow-assisting pipeline, main flow-assisting pipelines I and II, branch flow-assisting pipelines I and II, arc-shaped flow-assisting pipelines, semi-circular flow-assisting pipelines, pneumaticbutterfly valves and flow-assisting nozzles I and II; thus, the efficiency and the quality of mineral separation production are improved.

Description

technical field [0001] The invention belongs to a process device for beneficiation, in particular to a blockage removal device for a reinforced concrete silo. Background technique [0002] At present, the ore dressing plants of various mines are equipped with storage bins for mineral materials (ore) (hereinafter referred to as bins), which are used to adjust the production process, allocate ore selection paths, adjust the amount of ore input, and balance the mineral processing process. The types of silos can be divided into rectangular conical funnel silos, V-groove conjoined silos, and cylindrical flat-bottomed silos. When the mineral material enters the silo, the friction between the mineral material and the silo wall increases due to the difference in physical factors such as the moisture content, lumpiness and surface properties of the mineral material, and the mineral material cannot overcome the friction by its own gravity. The resistance prevents the mineral material...

Problems solved by technology

Although this scheme can play a certain role in clearing the clogged shed material of the rectangular cone-shaped funnel-shaped reinforced concrete silo, there are the following problems: this scheme is not suitable for the clearing of the cylindrical flat-bottomed reinforced concrete silo, mainly because : There are no four edges and corners inside the cylindrical flat-bottomed reinforced concrete silo, and it is impossible to install a pneumatic vibrating hammer. In addition, it is installed with a flow-aiding air duct inside the silo. During installation, the warehouse must be cleared before installation, thus affecting production. At the same time, the flow-aiding air duct is installed inside the silo, which wears out after a long time, and at the same time hinders the mineral materials in the silo from sliding down; in addition, Chinese patents ZL2009 2 0187426.7 and ZL2009 2 0187425.2 are all aimed at rectangular cone funnel-shaped reinforced concrete For silos, it is also not applicable to the cleaning of cylindrical flat-bottomed reinforced concrete silos
