A high-efficiency lime powder spraying machine

Abstract

The invention discloses an efficient lime powder sprayer, belongs to powder sprayers in the technical field of powder spraying and aims to provide an efficient lime powder sprayer. The efficient lime powder sprayer comprises a material barrel, a feeding adjusting hopper is arranged in an inner cavity of the material barrel, a feeding port of the feeding adjusting hopper penetrates out of the top of the material barrel, the bottom of the material barrel is connected with a driving motor, and a vibration stirring device is arranged in the material barrel and connected with the driving motor. One end of the bottom of the material barrel is connected with a discharging pipe, one end of the discharging pipe is communicated with a blowdown pipe, the middle of the blowdown pipe is communicated with the discharging pipe, and the other end of the blowdown pipe is connected with a fan. A secondary smashing device for protecting high-speed air flow from reverse flowing is further arranged between the material barrel and the blowdown pipe, the two ends of the secondary smashing device are communicated with the material barrel and the blowdown pipe through the discharging pipe, and the discharging pipe between the secondary smashing device and the material barrel is connected with an air inlet adjusting valve.

Description

technical field [0001] The invention belongs to the technical field of powder spraying and relates to a powder spraying machine. Background technique [0002] The powder spraying machine is a combination of hammer mill crushing and centrifugal blowing. It can grind raw coal less than 20mm into fine powder and spray it into the furnace for combustion. It has low coal consumption and high heat utilization rate. Its fuel is coal, which is the key heat source of various industrial kilns. The coal pulverizer is a combined machine of hammer mill crushing and centrifugal air supply. [0003] The coal that is used for various drying kiln fuels at present mostly puts coal directly into the kiln for combustion. Because the raw coal contains a large amount of coal particle fragments, these coal particle fragments cannot be fully burned and are converted into smoke and waste residue for discharge. It not only pollutes the environment, but also causes waste of energy, so coal pulverize...

AI Technical Summary

Problems solved by technology

Therefore, under the action of the centrifugal impeller, most of the high-speed airflow blows the coal powder out of the discharge port, but part of the high-speed airflow will reverse into the crushing chamber where the three sets of flyweights are located, and even overflow from the coal hopper, so It will affect the hammer grinding efficiency of the powder blower, and the overflow of coal powder into the coal hopper will seriously pollute the working environment of the staff, cause environmental pollution, and cause personal injury to the staff

In addition, since the final output of coal powder is processed by crushing, grinding, etc., the produced coal powder will have a large amount of charge, and when the coal powder is blown out, more coal powder will be charged under the action of the charge. Adsorbed to the discharge pipeline, and eventually accumulate more and more, so that the pipeline is finally blocked, reducing the efficiency of pulverized coal being blown out
