Abstract
The invention discloses a permeability detector of mixed minerals and a permeability improvement method of mixed minerals. The device provided by the invention comprises an air blower and a central processing unit. The air blower is communicated with the lower part of a silo for holding mixed minerals through an air tube, and a bypass of the air tube is provided with a differential pressure transmitter and a flow transmitter. Signal output ends of the differential pressure transmitter and the flow transmitter are respectively connected to the central processing unit. According to permeability, humidity in the silo is changed by adding water into the silo, and permeability of mixed minerals in the silo is further improved. According to the invention, permeability of mixed minerals can be effectively improved, and quality and output of sintered ore formed after sintering of mixed minerals are raised.
Description
Technical field
The present invention relates to mineral production field, specifically a kind of mixing ore deposit device for checking air permeability and mix the ore deposit method that has improved breathability.
Background technology
The gas penetration potential of mixing ore deposit, quality and the output of the sintering deposit directly forming after impact igniting, the gas penetration potential of mixing ore deposit is better, and its burning rate in chassis is faster, and the sintering deposit of producing has higher rotary drum coefficient.Impact mixes mixing ore particle degree because have, mix ore deposit ratio, mixing mineral water and divide several aspects of ore deposit gas penetration potential, the granularity of mixing ore deposit is constant substantially in a batch of material, the ratio of mixing ore deposit is what determine according to the requirement of technique and production, therefore, changing moisture in mixing ore deposit is the unique method that improves the gas penetration potential of mixing ore deposit.
Summary of the invention
The object of this invention is to provide a kind of mixing ore deposit device for checking air permeability and mix the ore deposit method that has improved breathability, to improve mixing ore deposit gas penetration potential.
In order to achieve the above object, the technical solution adopted in the present invention is:
Mix ore deposit device for checking air permeability, it is characterized in that: include fan blower, center processor, described fan blower is communicated with the feed bin bottom that is contained with mixing ore deposit by air hose, on air hose, bypass is communicated with pressure measuring tube, flow tube, on described pressure measuring tube, differential pressure transmitter is installed, on described flow tube, flow transmitter is installed, described differential pressure transmitter, flow transmitter signal output part access respectively center processor.
The mixing ore deposit method that has improved breathability, is characterized in that: first measure under constant pressure, air is by mixing the flow of ore deposit air inlet air hose in feed bin, then according to formula
the gas penetration potential that obtains mixing ore deposit in conjunction with pressure and flow COMPREHENSIVE CALCULATING, in formula: J is gas penetration potential index, F is gas flow m in air hose
3/ h, A is the ventilative area of air intake opening, and P is fan blower pressure kPa, and L is the ventilative segment length mm of air intake opening, and n is index; Then according to mixing ore deposit gas penetration potential, by adding the humidity of mixing ore deposit in water change feed bin to optimum humidity value, thereby make to mix ore deposit gas penetration potential in feed bin, reach optimum value in feed bin.
The present invention is by air pressure and data on flows in measurement mixing ore deposit, through calculating the gas penetration potential of mixing ore deposit, according to mixing humidity that ore deposit gas penetration potential selects suitable amount of water to change to mix ore deposit in feed bin to optimum humidity value, make the gas penetration potential of mixing ore deposit reach best.The present invention can effectively improve the gas penetration potential of mixing ore deposit, has improved quality and output that point mixes the sintering deposit forming after the sintering of ore deposit.
Accompanying drawing explanation
