Petroleum coke powder frequency conversion pump

Abstract

The present invention is a petroleum coke powder frequency conversion conveying pump, which includes a pump box connected to the bottom of the coke powder storage bin, a mixing chamber, and a frequency conversion motor, a shaft coupling, a bearing box and a spiral reamer connected in sequence, wherein the helical reamer wears After passing through the pump box, it is inserted into the spiral casing on one side of the pump box. At the outlet of the spiral casing, there is a powder cover that can swing around the rotating shaft above the casing. The mixing chamber includes an upper sealed A funnel and a horizontal air channel arranged at the lower part of the funnel, the powder cover is arranged in the upper part of the funnel, and an air inlet and a fluidized gas powder outlet are respectively arranged on the air channel. It has the advantages of stable work, reliable air lock performance, strong sealing, simple operation, convenient adjustment, few wearing parts and good practicability. It can be widely used for mixing other powdery materials besides petroleum coke powder. ,delivery.

Description

【Technical field】 [0001] The invention relates to a combustion system, in particular to a petroleum coke powder frequency conversion delivery pump in the combustion system using petroleum coke powder as fuel in the field of glass production. 【Background technique】 [0002] The glass industry is a high-energy-consuming industry, and the fuel cost accounts for about 30-50% of the glass cost, and the glass melting furnace is the equipment that consumes the most energy in the glass production line. At present, the fuel used in the glass field is basically heavy fuel oil such as petroleum. We know that the energy of our earth is limited. With the development of the economy, the demand for energy will increase. On the other hand, people are concerned about environmental protection. Awareness is rising day by day, and the general practice of mankind is to hope for breakthroughs in renewable energy and to improve energy utilization. As the most important fuel for human beings, petr...

AI Technical Summary

Problems solved by technology

my country has entered the era of heavy chemical industry. With the continuous increase of energy demand, imported crude oil and my country's self-produced crude oil are about 350 million tons. According to the calculation that 3-5% of petroleum coke can be produced during crude oil refining, my country will output more than 10 million tons per year. tons of petroleum coke, so far, petroleum coke powder has not been included in the national energy sequence, and the national energy consumption statistics have not been included in the energy consumption indicators
