Mobile asphalt batching plant for bitumen decanter
» Brief Introduction
With the rapid development of highway construction,the increase of
demand of asphalt,asphalt in convenient to transport,easy to
store,etc widely used,especially in high grade highway using
imported high-performance asphalt most buckets of form,which
requires melting speed,take off a
bucket of clean,also can prevent the asphalt aging of asphalt
barrels off device.
DLT6 type asphalt bucket removal device developed and produced by
our company uses heat conducting oil as heat
carrier,heating,melting and bucket removal of asphalt through
heating coil.The device can ensure the heating quality of
asphalt,with high thermal efficiency,high speed of asphalt bucket
removal,improve labor intensity,reduce pollution and other
characteristics.
» Structure and working principle
DLT6000 asphalt bucket removal device is mainly composed of bucket
removal box,lifting methanism,hydraulic push device and electrical
control system.The box body is divided into two chambers,the upper
chamber is barrels of asphalt melting chamber,all around are
distributed with heating coil,heating tube and asphalt barrel
mainly by radiation heat exchange,to achieve the purpose of asphalt
bucket,two rails,for the asphalt barrel into the track. The lower
chamber is mainly to continue to heat the asphalt out of the
barrel,so that the temperature reaches the pump
temperature(120℃),and then the asphalt pump into the high
temperature tank,if the heating time can be extended to obtain a
higher temperature.The lifting mechanism adopts cantilever
structure.The asphalt bucket is lifted by electric hoist,and then
the asphalt bucket is placed on the guide rail by lateral
movement.Then the bucket is pushed into the upper chamber by
hydraulic propeller,and at the same time,an emppty bucket is pushed
out at the rear exit.There is no oil groove on the platform at the
entrance of the asphalt drum to prevenr dripping asphalt from
flowing out.
The import and export door of the device adopts spring automatic
closing mechansim,and the asphalt barrel can be automatically
closed by pushing out the back door to reduce heat loss.The asphalt
outlet is provided with a thermometer to observe the asphalt outlet
temperature.The electric control system can ontrol the opening and
closing of hydraulic pump and the directional change of
electromagnetic vavle to realize the advance and retreat of
hydraulic cylinder.

» Installation and operation
1.Make the foundation according to the equipment foundation drawing
before installation.In order to reduce thrust,the foundation can be
made into a slope of about 0.2%(along the movement direction of the
barrel).
2.The hydraulic propeller support and hanger are fixed with bolts
and the platform of bucket removal device.The cantilever and hanger
are connected with bolts through the flat plate.
3.When connecting the heating pipes of the bucket removing
device,pay attention to the direction of the inlet and outlet
pipelines of the heat conduction oil in the upper and lower
chambers to avoid wrong connection.
4.The operator must understand the equipment structure,working
principle,as well as the use and rotation of the vavle.
5.Check whether all kinds of valves and instruments are normal
before starting the machine.Whether the hydraulic tank is filled
with hydraulic oil.
6.When the bucket removing device starts to work,the heat
conduction oil valve should be opend one hour in advance to make
the device reach the normal working temperature.
7.Open the key switch of the control cabinet,start the hydralic oil
pump motor,and adjust the working pressure of the hydraulic system
to 0.4mpa.
8.Invert the asphalt bucket with the ground(opening down),lift the
asphalt bucket by the electric hoist,and place it on the entrance
rail.
9.Start the forward button of the hydraulic cylinder of the control
cabinet,push the barrel into the bucket removing device,and then
operate the back button of the hydraulic cylinder.
10.Pay attention to the storage and temperature of the bucket
removal device,and open the asphalt pump to extract asphalt when
meeting the requirements.
11.In order to avoid the asphalt barrel falling directly to the
ground,the user can make an inclined plane(which can be welded by
steel bar)and set up an oil collecting pool at the bottom to
collect the asphalt that does not drop clean.
» Maintenance
1.The surroundings of the bucket removing device must be kept
clean,and the site must be cleaned and asphalt barrels sorted out
after the machine is shut down.Check all kinds of valves and in
struments frenquently.
2.Often check whether the asphalt pump,gear oil
pump,electromagnetic valve,oil cylinder,electric hoist and other
parts work normally,find problems and deal with them in time.
3.Often check whether the asphalt outlet is smooth,work for a
period of time through the sewage hole to eliminate the dirt at the
bottom of the chamber.
4.Often check and clean the hydraulic system,found oil pollution
should be replaced in time.
