Maintenance techniques of asphalt mixing station

Bubble atomization
Bubble atomization is the injection of compressed air into the nozzle upstream flow of liquid, in the bubble generator to form a liquid bubble flow, it flows through the mixing tube to reach the conical convergence section (see photo), at this time the number of bubbles increased, the average diameter of the bubble will increase due to bubble expansion; At the same time, due to the acceleration of bubbles and In the liquid two-phase flow of turbulent pulsation, some bubbles will break into smaller bubbles, bubbles ejected from the nozzle, will generally explode into droplets.

In the asphalt mixing station, there is a more important system, called fuel oil supply system.
The main components of the system are: fuel tanks, fuel pumps and pipelines.
The main function of the system is to suck out the oil in the fuel tank by means of a fuel pump, which is used to supply the burner through a pressure relief valve, a stress gauge and a flowmeter.
Fuel tanks, on the other hand, are used to store fuel to facilitate the supply of burners.

In the pavement construction project, the work quality of the asphalt mixing station plays a very important role, so it can be understood that the working performance of the asphalt mixing station and its specific working conditions will directly affect the quality of the asphalt mixture, which will affect the progress and quality of the whole project.
Therefore, in the whole process of work, we need to grasp the main points of each work.

Not only that, the development of asphalt mixing station industry can also better promote the development of related industries, will be very conducive to the future level of the entire industrial chain to promote the implementation and promotion.
We hope that in the future, it will further promote the development of the entire industry, for the relevant industries to play a positive role in driving.

The smaller the diameter of the oil droplet atomization, the shorter the burnout time, the higher the combustion thermal efficiency.
The test results show that the kerosene beads with a diameter of 1mm need to burn out in the air for about 1s; the diameter is 0.
The 1mm kerosene beads require about 0.
01s; diameter 0.
The 05mm kerosene beads require about 2.
5μs.
The test shows that if the diameter of the oil bead is reduced to 1/20, the burnout time can be shortened to 1/400.
When larger droplets of oil burn, a cracking reaction occurs at high temperatures and hypoxia, producing micro-carbon particles that do not allow the heat of the fuel to be fully released and emit black smoke when burned.
The purpose of the atomization of liquid fuel is to form a very small diameter particle through atomization, that is, to form a very uniform size of the liquid mist, in order to increase the contact area between liquid fuel and air, to obtain a better combustion effect.

Mobile Asphalt Plant Mixing station rolling system will affect the work efficiency, is to ensure that the hopper can operate correctly to the proper position when necessary at the construction site.
The large nut adjustment of the rear seat of the motor can adjust the size of the power moment, remove the connecting screw between the locking nut and the fan brake, back the locking nut to the appropriate position, move the rotor to the ultimate position in the direction of the shaft, and then move the fan brake back, so that the brake ring and the rear cover inside the conical surface bonding After contact with the end surface of the fan brake, then spin into a circle, and finally tighten the connecting screws.
If the hopper appears abnormal braking, the locking nut back to the appropriate position, and then the end of the hexagon bolt clockwise tightening, such as the start of the lifting motor when the stuffy car, then the locking nut back to the appropriate position, and then the end of the hexagon bolt loosened, lengthen the inner brake distance, in the locking nut tightening.

Asphalt mixers are used in highway construction, and if this type of equipment is differentiated according to power, there can also be differences between civil and engineering.
Apart from the difference in productivity between the two, what are the differences?

Among them, the control of the mixture oil oilstone is a work point that can not be ignored.
And in the asphalt mixing station work, we usually choose an asphalt mixture of the best oil and stone ratio to produce.
The so-called optimum oil-stone ratio is mainly determined by the grading of the ore and the content of the powder.
In fact, the oil-stone ratio can be regarded as the fundamental guarantee of pavement strength and its performance.
Regardless of whether the amount of asphalt is too large or too small, it will have a certain negative impact on road construction.

The above is for everyone to prepare the asphalt mixing station mixture of oil and stone ratio control and fuel oil supply system of these two aspects of the content, I hope that in the future work, we can pay attention to this problem, as far as possible to ensure the quality of asphalt mixing station work.
