Analysis on competition pattern of asphalt mixer industry

Security for any device is the focus, asphalt mixer Of course there is no exception, today to share with you is also this knowledge, that is, asphalt mixer safety operation norms, may wish to pay attention to it.

.


In addition, after the completion of the work to clean up the asphalt mixer, and can not have water residue in the cylinder, so as to avoid rust of the barrel and blades.
Finally, you should brakes the power outage and lock the switch box to ensure safety.

The silo of the finished silo is composed of three storage silos, and each storage silo is equipped with an acoustic and optical alarm. At the same time, according to the size of the loading trolley, each storage warehouse also has a feed port.
Its doors are operated by electric pneumatic, so the loss of heat can be prevented after the feed has ended and closed.

n

　　Dust (large particles and small particles) that fall through the bottom of the box are measured by each screw conveyor according to the actual production of the mixture than the flow of zinc powder metering storage silo or recovery powder storage warehouse.

n

　　The dust collector of all dust bags to check, to achieve the "two do not let go" of the inspection principle.
Do not miss any broken dust bags, two do not let go of any clogged dust bags.
The repair of dust bag should adopt the principle of "rehabilitation" and mend the principle of saving energy and saving cost.
Carefully check the sealing connection device, the damaged or invalid gasket or rubber ring should be repaired or replaced in a timely manner.

Asphalt Concrete Mixing Station (hereinafter referred to as: Asphalt station) is an important equipment for the construction of high-grade highway pavement, which brings together various technologies such as mechanical, electrical and concrete foundation production.
At present, in the construction of infrastructure projects, people's awareness of environmental protection, promote energy conservation and emission reduction, rehabilitation awareness enhancement, so the performance of asphalt station dust removal equipment, the advantages and disadvantages are not only directly related to the quality of the finished asphalt mixture, but also the equipment manufacturer's technical level and equipment personnel operation, Maintenance awareness has put forward higher requirements.

t

　　The device runs about 1000 hours or so when the dust collector's pipe comes out of not only high-speed hot air flow, but also with a large number of gray grains, and operators found that the bag blockage is very serious, a large number of cloth bags have broken holes, pulse spray blowpipe There are some sand eyes, dust bag replacement frequently.
After technical exchanges and communication with the manufacturers of Japanese experts, it is concluded that the dust collector factory due to the defects of the production process caused by the deformation of the Dust collector box, the dust collector porous plate deformation and spray blowpipe jet air flow is not vertical caused by the deflection angle and spray blowpipe on the root cause of the broken cloth bag.
Without the damage, the hot air flow with gray grains will be carried directly through the dust bag-flue-the chimney-chimneys-atmosphere.
If not carried out a thorough rectification, not only will the enterprise put into the equipment maintenance costs and production costs greatly strengthened, reduce production efficiency and quality and serious pollution of the ecological environment, resulting in a vicious circle.

r

　　Because the dust collector porous plate has been seriously deformed, can not be thoroughly corrected, replace the porous plate (in order to replace the multi-piece connection type), the Dust collector box tensile correction, the bearing of the supporting beam for a thorough correction.

In order to avoid the asphalt mixer in the working process of moving, the equipment should be placed in a flat position, at the same time with square wood pad front and rear axle, so that the tire put high overhead.
At the same time, the Asphalt Batch Mix Plant mixer should be two-stage leakage protection, when the inspection, trial operation and other links are qualified before starting.

.


In the use of the process, we must ensure that the rotation direction of the mixer is consistent with the direction indicated by the arrow, if there is no discrepancy, should also be adjusted by correcting the motor wiring.
After the boot, often pay attention to the mixer parts of the operation is normal, the same is true when the shutdown, can not occur abnormally.

t

　　Taking tap-4000lb asphalt station in Tanaka as an example, the dust removal equipment adopts belt dust removal method as a whole, which is divided into two parts of gravity box dust removal and belt type dust removal.
Among them, the control machinery is equipped with: Exhaust fan (90kw*2), servo motor control air volume regulator valve, belt type dust collector pulse generator and control solenoid valve.
Auxiliary execution mechanical mechanism is equipped with: chimney, pipe, airway and so on.
Dust removal cross-sectional area of about 910m2, unit time dust removal capacity can reach about 13000m2/h.
Dust removal equipment operation can be roughly divided into three parts: separation and dust-cycle operation-dust removal (wet treatment)
