Pneumatic solid particle feeding system

Abstract

The invention relates to a pneumatic solid particle feeding system which comprises a main blowing pipe, a feeding pipe and a hopper. The feeding pipe is used for conveying solid particles from the hopper, and the main blowing pipe is used for providing conveying air for conveying the solid particles for the feeding pipe. The pneumatic solid particle feeding system is characterized in that an end notch of an air outlet of the main blowing pipe is flush with the side, close to the end of the feeding pipe, of a discharging opening of the hopper, and at least part of the end notch of the air outlet of the main blowing pipe inclines, so that the conveying air blown by the main blowing pipe has a vector in at least one other direction besides the horizontal direction. By means of the pneumatic solid particle feeding system, the shapes of solid materials can be kept good, and the pipeline blocking phenomenon is avoided. The pneumatic solid particle feeding system is directly connected with an inlet pipe of a device reactor through the feeding pipe in a sealed mode, and therefore the continuous material conveying process can be achieved, energy consumption is lowered, and environment pollution is avoided.

Description

technical field [0001] The invention relates to a material conveying device, in particular to a solid particle pneumatic feeding system. Background technique [0002] At present, in the high-temperature refining and purification devices of various solid particles (especially mineral particles), due to the high-temperature environment in the equipment and the characteristics of solid substances, people mostly use screw / ribbon conveyors, high-level feed Due to the harsh conditions of the high-temperature equipment following the feeder, the inlet pipe and facilities of the feeder are often burned at high temperatures, and the crushing, dust, blockage, and melting of mineral particles during transportation, and People are more concerned about the accompanying problems such as high energy consumption and environmental pollution. [0003] Patent No. CN204247156U discloses a high-level material tank, and specifically discloses a cylinder body, the cylinder body is provided with an...

Problems solved by technology

Then take the vertical line of the port of the air outlet as the dividing line, and the part of the material at the rear of the dividing line (that is, the side opposite to the air flow direction is called the rear side) will fall on the bottom of the feeding pipe, and there is no material here. The air flow causes the material to form a pile here, so it cannot be guaranteed that all the material will form a fluidized material

However, the blowing pipe arranged on the center line of the feeding pipe makes the gas flow in the horizontal direction due to its vertical cut, so it is difficult to blow up the solid particles deposited on the lower part of the feeding pipe.

Therefore, the gas flow will automatically flow through the part of the top of the feeding pipe that is not blocked by solid particles, and the solid particle material cannot be fluidized and transported to the equipment reactor, that is, the phenomenon of "blowing half-pipe short circuit" occurs

As a result, the final gas fluidized conveying device cannot be used normally due to the blockage of the material

Not only wasted a lot of materials, but also required manual dredging and increased more human and material resources
