The sealing flange here serves for the connection and sealing of the pipes. And one ends of the nitrogen conveying pipes, which are far away from the multi-pipe sealing disc, are connected to the main vent pipe. A plurality of nitrogen gas conveying pipes are connected to a main vent pipe, and the main vent pipe is connected with a nitrogen gas tank, so that multi-pipeline conveying of nitrogen gas is avoided. The nitrogen conveying pipe is connected with the main vent pipe in a sealing flange mode. The sealing flange connection at the position is convenient to disassemble when the pipeline is maintained or replaced. And valves are respectively arranged on the nitrogen conveying pipes. The valve can be used for adjusting the gas flow in the pipeline, the main vent pipe is perpendicular to the nitrogen conveying pipe, one end of the main vent pipe is connected with the nitrogen tank, and the other end of the main vent pipe is provided with a breather valve. The breather valve is used for maintaining the air pressure balance in the main breather pipe and avoiding the overpressure of the air flow conveying pipeline so as to damage the pipeline. And the inner walls of the discharging pipe and the feeding pipe are coated with acid-resistant and anti-corrosion layers. In the production process of lithium hexafluorophosphate, the raw materials comprise hydrofluoric acid, so that an acid-resistant and anti-corrosion layer needs to be arranged, the service life of the device is prolonged, the content of metal impurities in the product is reduced, and the quality of the product is improved.
In order to facilitate maintenance or replacement of the valve on the nitrogen conveying pipe and ensure a sealed environment in the device replacement process, preferably, the nitrogen conveying pipe is formed by connecting two sections of circular pipes, and the connecting mode is sealing flange connection. Further preferably, the valve is arranged on a section of the nitrogen conveying pipe connected with the main vent pipe. When the valve need be maintained or changed, can directly dismantle one section nitrogen gas conveyer pipe that is connected with main breather pipe to quick replacement is favorable to maintaining the interior environment of crystallization drying device.
The utility model discloses in still including other subassemblies that can make this heterogeneous circulation seal rotary conveyor normal use, all belong to the conventional selection in this field. In addition, the device or the assembly which is not limited in the utility model adopts the conventional means in the field, for example, the sealing connection between the multi-pipe sealing disc flange plate and the flange plate can be arranged according to the prior art.
The utility model discloses a heterogeneous circulation seals rotary conveyor's beneficial effect does:
1. the feeding pipe, the discharging pipe, the joints of the six nitrogen conveying pipes and the valves are integrated on one rotary joint, so that the operation and the maintenance of operators are facilitated, and the labor force is saved;
2. the device does not need to be disassembled in multiple sections in the maintenance process, so that the probability of contact between the device and the air is reduced, and the environment in the device is maintained.
The utility model discloses a set up the sealed rotary conveyor of heterogeneous circulation rationally, with different media and gas propelling movement pipeline and valve centralized control among the rotary drying crystallization device, the labour has been practiced thrift in convenient operation, has also made things convenient for the maintenance of equipment simultaneously, in the maintenance process, is favorable to reducing the probability of medium and air contact, and the internal environment of maintenance device does not make the medium scrap because of the oxidation to economic risk has been reduced.
