and the pressure gauge 6 is arranged on the conveying pipeline 2 and is positioned between the first valve 4 and the second valve 5.
The utility model discloses a material delivery system, when needs are carried the material from storage silo 1 to sending jar 3, first valve 4 and second valve 5 are opened simultaneously, and the material can get into through pipeline 2 and send in jar 3. When the material needs to be conveyed outwards from the sending tank 3, the first valve 4 and the second valve 5 are closed simultaneously, and positive pressure gas is introduced into the first gas inlet pipeline 33, so that the material in the sending tank 3 is lifted, and the material is conveyed outwards through the tank outlet 32 of the sending tank 3. In this embodiment, the positive pressure gas is a compressed gas. Because the first valve 4 and the second valve 5 are sequentially arranged along the material conveying direction of the conveying pipeline 2, when the positive pressure gas introduced from the first gas inlet pipeline 33 enters the sending tank 3, the second valve 5 directly bears the gas pressure in the sending tank 3 to play a main sealing role; when the second valve 5 fails in sealing, positive pressure gas can pass through the second valve 5, and at the moment, the sealing action of the first valve 4 can still ensure that the positive pressure gas does not enter the storage bin 1 above, so that the first valve 4 and the second valve 5 realize a double-valve sealing protection structure, and the problem that the storage bin 1 is sprayed outwards from the bin inlet due to sealing failure can be avoided;
in addition, because be equipped with manometer 6 between first valve 4 and the second valve 5, so manometer 6 can detect the gas pressure of following second valve 5 exhaust, and the staff can judge the sealed condition of failing of second valve 5 through the gas pressure value that shows on manometer 6 to the staff in time changes second valve 5. In this embodiment, the worker presets the normal pressure value of the area of the conveying pipeline 2 between the first valve 4 and the second valve 5, and when the gas pressure value displayed on the pressure gauge 6 is greater than the normal pressure value, the worker determines that the sealing of the second valve 5 is invalid.
The first valve 4 and the second valve 5 are both butterfly valves. The butterfly valve has small volume and light structure, so the space occupied by the conveying pipeline 2 is small; because the material can adhere on first valve 4 and second valve 5, and first valve 4 and second valve 5 use frequently, this all can cause the damage of first valve 4 and second valve 5, and when adopting the butterfly valve, the valve plate of butterfly valve is changed conveniently, and the staff of being convenient for is to the maintenance of first valve 4 and second valve 5.
The storage bin 1, the conveying pipeline 2 and the sending tank 3 are sequentially arranged from top to bottom. This structure makes the material from storage silo 1 to sending jar 3 transport can be along vertical direction, by carrying from the top down, the material of being convenient for is carried fast and stably.
The conveying pipeline 2 is provided with a dosing device 7, and the dosing device 7 is arranged between the first valve 4 and a bin outlet 11 of the storage bin 1. The dosing device 7 can achieve dosing of the delivery tank 3, adjusting the feeding schedule.
The quantitative feeding device 7 is a star-shaped feeder which can convey materials in equal volume. In this embodiment, the star feeder includes a rotating shaft 71 and a plurality of plates 72, the rotating shaft 71 is rotatably installed inside the conveying pipe 2, the plurality of plates 72 are sequentially arranged along the circumferential direction of the outer circumferential surface of the rotating shaft 71, and the intervals between two adjacent plates 72 are the same. The rotating shaft 71 is connected with the output end of the motor. The feeding rate can be adjusted by controlling the rotation speed of the rotating shaft 71 through the motor.
The dosing device 7 is not limited to this star feeder, but only needs to have any other structure that can perform the dosing function.

The material sending system further comprises: the material pipeline 8, the material pipeline 8 is connected with the tank body outlet 32 of the sending tank 3; the level of the material outlet 81 of the material conduit 8 is higher than the level of the top end of the storage silo 1. This enables the material outlet 81 of the material pipe 8 to be connected to the elevated bunker. Because this system has realized the sealed protection architecture of dual valve, so can fill into great atmospheric pressure to sending jar 3, this just makes the material can carry the material export 81 of the higher material pipeline of level 8 to make the material can transport into high-order feed bin.
Since the end of the sending tank 3 provided with the tank inlet 31 is provided with the first air inlet pipe 33, the second valve 5 is provided at the discharge port 22 of the delivery pipe 2. The gas pressure in the sending tank 3 can act rapidly on the second valve 5, which can improve the sensitivity of the monitoring of the seal failure condition of the second valve 5.
