[0034] The material properties conveyed by the conveying system disclosed in the utility model are shown in Table 1 below.
[0035] Table 1 Material conveying characteristics
[0036]
[0037] When in use, the suction tank truck 2 transports the material in the tank truck to the silo 3 through the conveying pipeline 9 connected to the silo 3. When loading, the exhaust valve and feed valve of the silo pump 4 are opened, and the material enters the silo pump 4 from the outlet of the silo through the feed valve. At this time, the compressed air inlet valve and outlet valve output by the conveying gas source tank 1 are closed. Of course, you can also choose to open the corresponding valve to inlet air to the outlet of the silo to assist the material to enter the silo pump. When the material fills the silo pump 4, the feed valve and exhaust valve are closed; then the outlet valve and inlet valve are opened. The compressed air passes through the mixing box at the bottom of the silo pump 4 to press the material into the pipeline connected to the alkali dissolving tank 5. The compressed air is continuously supplied to the silo pump from the inlet valve until all the materials in the silo pump are discharged.
[0038] The compressed air enters the silo pump through the non-return valve, and enters the tangential airflow through the fluidizing pipe 11 to increase the fluidization concentration of the material and prevent the material from settling at the outlet. The automatic steam trap 7 is connected to the main air intake pipe of the silo pump, that is, the branch pipe 10, to prevent the soda ash from absorbing moisture and agglomerating to block the pipe. The weighing module on the silo pump leg is used as a level meter on the one hand, and for the rough measurement of the amount of material being transported on the other hand.
[0039] Each component in the conveying system disclosed by the utility model is controlled by a controller, that is, the weighing module, the valves on each component, etc. are connected to the controller, so that the entire conveying system can automatically adjust the various working states of the conveying system, measure the relevant process parameters, and according to the measurement results, the system performs closed-loop control on the silo pump. The controller is equipped with three material level modes: material level meter material level, timed material level, and manual material level. The material level meter material level mode is the main one, supplemented by the timed material level mode and the manual material level mode to ensure the stability of the system operation.
