Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a sending tank with controllable negative pressure feeding. Background Technique

[0002] The high-pressure sending tank conveying system, also known as the silo pump conveying system, is a type of positive and negative pressure pneumatic conveying system. It usually conveys in a dense phase. The dense phase pump uses a high-quality dome valve or double butterfly valve for discharging. After the dense phase pump is completely filled, the dome valve sphere passes through the material to close and seal. Compressed air enters the dense phase pump through a control valve, and the material enters the conveying pipeline at a low speed according to specific system requirements. During the feeding process, the material is added into the sending tank through a double butterfly valve or an expansion butterfly valve, and the displaced air is released through an exhaust valve, making the feeding easier. At the same time, it also solves the reverse pressure that hinders the material flow. This conveying method only requires a small amount of compressed air, achieves a high material-air ratio, ensures low energy consumption and very little system wear.

[0003] The negative pressure of the existing sending tank is formed by a negative pressure generator, and then the negative pressure is circulated through a butterfly valve. The design of the butterfly valve is a traditional setting. The butterfly valve is opened or closed by a motor one, with a single function and great limitations. Moreover, the size of the negative pressure gas generated by the negative pressure generator is also uncontrollable. Content of the Utility Model
