Gas and powder mixed conveying equipment

Abstract

The invention provides gas and powder mixed conveying equipment which is characterized in that a gas inlet air pipe is connected with a conveying pipe, a necking nozzle is arranged at the joint of the gas inlet air pipe and the conveying pipe and faces the conveying pipe, and the caliber of the necking nozzle is gradually reduced; a fluidization box is connected to the position, close to the necking nozzle, of the material conveying pipe on the right side of the necking nozzle, and the fluidization box is obliquely arranged above the material conveying pipe and communicates with the material conveying pipe. A powder feeding hole is formed in the upper part of the fluidization box; a fluidization plate is arranged on the side wall of the fluidization box and is used for receiving powder in the fluidization box; a ventilation device is arranged on the side, away from the fluidization box, of the fluidization plate, an inflation box is arranged on one side of the ventilation device, and pressure gas in the inflation box enters the fluidization plate through the ventilation device. And the aeration tank is communicated with the air inlet pipe through a breather pipe.

Description

technical field [0001] The invention relates to a mixing and conveying device, in particular to a device for mixing and conveying gas and powder. Background technique [0002] At present, the core difficulty in the gas transportation process of powder is the mixing of gas and powder. If the mixing of gas and powder is not uniform, it will cause the separation of gas and material, which will not only waste energy during transportation, but also affect the on-site use process. And because the gas is in a positive pressure state when the general gas is transported, the equipment is required to solve the problem of anti-wind. For example, during the pulverized coal transportation process, the pulverized coal and air (gas) are mixed unevenly, and the pulverized coal will accumulate at the bottom of the pipeline. When enough deposits are made, the wind pressure of coal transportation will be increased, and then the pulverized coal will be blown away together and the wind pressure...
