Energy-saving air-seal pneumatic conveying pump

Abstract

An energy-saving air-seal pneumatic conveying pump comprises a jet pneumatic conveying pump. The jet pneumatic conveying pump comprises an accommodating chamber. An air source connecting pipe communicated with the accommodating chamber is arranged at one end of the accommodating chamber. A Venturi communicated with the accommodating chamber is arranged at the other end of the accommodating chamber. A nozzle is arranged on one side of the accommodating chamber. An air-seal jet device communicated with the accommodating chamber is arranged on the other side of the accommodating chamber. The air-seal jet device is positioned above the accommodating chamber. The energy-saving air-seal pneumatic conveying pump integrates the technology principles of negative-pressure jetting, positive-pressure air locking and Venturi jetting, the continuous conveying of powdery materials and granular materials is realized, the materials are sufficiently mixed with gas sufficiently under the action of the air-seal jet device before entering the accommodating chamber, and the materials are fluidified to enable the jet pneumatic conveying pump to operate in a more efficient and energy-saving manner; the materials enter the accommodating chamber under a certain of pressure through the air-seal jet device, so as to prevent pressure hysteresis effectively; and the air-seal jet device can replace a mechanical air locking device, so that the using cost can be effectively reduced.

Description

technical field [0001] The invention relates to an energy-saving air-sealed pneumatic conveying pump. Background technique [0002] Pipeline pneumatic conveying is a common conveying method in the field of industrial material conveying. In the continuous pneumatic conveying system, the pneumatic conveying pump is a common conveying device. [0003] Most of the existing pneumatic conveying pumps are jet-type pneumatic conveying pumps. In order to ensure continuous conveying, it is necessary to install an air lock (feeder) at the upper end of the storage room. When the pressure range enters another pressure range, air channeling occurs to maintain the smooth circulation of powdery or granular materials. [0004] Jet-type pneumatic conveying pumps have high requirements on the material and machining accuracy of the airlock, the airlock wears quickly, the cost of use is high, the airlock pressure is limited, affects the conveying distance, and requires a certain amount of elect...
