Device capable of remotely controlling flow direction of materials

Abstract

The invention relates to a device capable of remotely controlling a flow direction of materials, which comprises a receiving tank (9) and a conveying pipe (8) arranged on the top of the receiving tank (9); the device is characterized in that a vertically communicated cone barrel (7) is arranged in the center of the receiving tank (9); the conveying pipe (8) is extended in the cone barrel (7); a control module for controlling the rotation of the cone barrel (7) is arranged outside the receiving tank (9), and includes an electric drive (1) and a bevel gear set connected with the electric drive (1) by a first transmission shaft (2); and the bevel gear set is connected with the cone barrel (7) by a second transmission shaft (6) which is extended in the receiving tank (9), and drives the second transmission shaft (6) to take the cone barrel (7) to rotate by surrounding an axis of the second transmission shaft (6). The device disclosed by the invention can realize remote control of the flow direction of the materials; the control module is not contacted with the materials so as to guarantee the flexibility and the service life thereof; and the device is particularly suitable for a radioactive working condition, so that the operator can be prevented from suffering from the radiation hazards.

Description

technical field [0001] The invention belongs to the technical field of material flow direction control, and in particular relates to a device capable of remotely controlling the material flow direction. Background technique [0002] When a nuclear power plant uses a settling centrifuge to process radioactive material liquid, due to the extremely high radioactive level of the processed material liquid, the settling centrifuge is arranged in the equipment room, and the operator controls the centrifuge through remote control. In actual operation, when the decanter centrifuge is feeding, there will be a very small amount of feed liquid remaining in the feeding pipe, which will drip during other operations, and will be discharged with the flushing water of the waste residue, resulting in the loss of precious materials. In order to prevent the loss of the material liquid, a switching device should be installed at the outlet of the material liquid during the feeding process, and th...

Problems solved by technology

However, conventional switching devices such as valves cannot be used here due to high matching precision, sensitivity to the slag content of the feed liquid, and the inability of operators to enter the equipment room for maintenance due to the high radioactivity level in the equipment room.
