11. A pneumatic conveying system, characterized by comprising a material receiving device (02) and a plurality of bin pumps (01) according to any one of claims 1 to 10, wherein the inflating part (2) is communicated with each bin pump (01), discharge ports of the bin pumps (01) are communicated, and the discharge port of the most downstream bin pump (01) is communicated with the material receiving device (02).
12. A method for measuring the mass of materials in a bin pump is characterized by comprising the following steps:
introducing materials into the bin body (1);
after the feeding is finished, sealing the bin body (1) and inflating the bin body (1);
determining the volume of gas in the bin body (1) when the gas filling is stopped, wherein the mass of the material in the bin body (1) is calculated as follows:
M＝(V-V2)×ρ
wherein V is the total volume of the bin body (1), V2The volume of the gas which is fed into the bin body (1) when the gas filling is stopped, and rho is the density of the material.
13. The method for measuring the mass of the materials in the bin pump according to claim 12, wherein the method for determining the volume of the gas which is fed into the bin (1) when the gas filling is stopped comprises the following steps:
detecting and obtaining the air inflow of the gas when the gas is stopped to be inflated, the first temperature when the gas does not enter the cabin body (1) and the second temperature in the cabin body (1), wherein the volume of the gas which is admitted into the cabin body (1) is calculated as follows:
wherein: p1The pressure of the gas is not introduced into the bin body (1); v1Is the air inflow in the bin body (1); t is1The temperature of the gas is not introduced into the bin body (1); p2Is the gas pressure in the bin body (1); t is2Is the temperature in the bin body (1).
14. The method of claim 12, wherein the alarm signals that the material is in place and stops the material from being introduced.
