Embodiment Construction

[0021] see figure 2 , the positive pressure conveying method of light powder and pellets according to the present invention, the material stored in the source bin 1 is conveyed to the sending tank 3 through the feed pipeline 2, and the sending tank 3 passes through the conveying pipeline L0, the control valve and the pulling method The pipe 4 transports the material to the destination silo 5 by the conveying gas; during this period, a pressurized gas pipeline L1 and a gas pipeline L2 and corresponding control valves are drawn from the conveying pipeline in front of the Lafa pipe 4. The other end of the compressed air line L1 is connected to the sending tank 3, and the sending tank 3 is pressurized; a suction nozzle 6 is set in the gas delivery line L2, and a suction line L21 is connected to the air suction nozzle 6 from the suction nozzle 6. The sending tank 3 is described, and the sending tank 3 is sprayed and sucked to realize accelerated feeding; under the combined action ...

Abstract

According to a positive-pressure conveying method for light powder and particle materials, the materials stored in a source stock bin are conveyed to a sending tank through a feeding pipe, and the sending tank conveys the materials to a target stock bin through a conveying pipeline and an laval pipe by conveying gas; during the period, a pressurizing gas pipeline and a gas conveying pipeline are led out from the conveying pipeline in front of the laval pipe, and the other end of the pressurizing gas pipeline is connected to the sending tank to pressurize the sending tank; an air suction nozzleis arranged in the gas conveying pipeline, an air suction pipeline is connected to the sending tank from the air suction nozzle, jet air suction is conducted on the sending tank to achieve accelerated feeding, and meanwhile air is exhausted to the target stock bin through an air exhaust pipeline; and under the combined action of pressurizing the sending tank and sucking the air into the sending tank to achieve accelerated feeding, positive-pressure conveying of the light powder and particle materials is achieved.

Description

technical field [0001] The invention relates to material conveying technology, in particular to a positive pressure conveying method for light powder and granular materials. Background technique [0002] Light materials (such as white carbon black (fumed silica), due to the low bulk density of the material, it is difficult for the material to fall into the conveying system under the condition of positive pressure conveying, resulting in insufficient conveying capacity. [0003] Most of the conveying system of fumed silica can only be conveyed by Venturi jet suction or negative pressure suction, such as figure 1 As shown: the storage bin 10 passes through the feed hopper 20, and the injection feeder 30 uses the pressure of the factory wind to generate a certain degree of vacuum at the nozzle through the injection feeder 30, so that the upstream light materials are sucked into the conveying pipeline and passed through After mixing in a certain mixing section, the material is ...
