Description
Technical field:
A kind of soft start rotary screen of the utility model belongs to screening plant field more particularly to soft start rotary screen.
Background technique:
In ore extraction, when screening of ore essential a part, existing rotary screen is mostly single layer, and in roller
There is axis, since the larger deformation for easily causing roller inner shaft of the quality of ore even damages, and one kind can only be screened in screening process
The ore of partial size causes screening efficiency lower, delays the duration；The existing complicated quality of Double-layer revolving drum screen connection structure is big, causes to drive
Dynamic structure is complicated and consumes energy, and main shaft is easy to wear in roller.
Meanwhile producing rotary screen is mostly being continuously increased, to rotary screen within diameter of phi 1.6m, with coal production scale
Sieving capacity requirement it is also higher and higher, diameter also has Φ 1.6m to increase to Φ 2.5m, power also has original 11KW to increase to
30KW, the demand that equipment even running is had been unable to meet with reduced-voltage starting is directly initiated.
Summary of the invention:
That the purpose of this utility model is to provide a kind of screening efficiencies is high, structure is simple, the reasonable soft start of drive system
Rotary screen.
The object of the present invention is achieved like this, and a kind of soft start rotary screen specifically includes that rack, rack-mounted
Rotary screen, motor, deceleration device, and it is mounted on the support wheel of the rack other side, the motor, deceleration device and rotary screen rotate
Linkage ring flange on main shaft is connected, and the rotary screen includes interior mesh screen and outer mesh screen, and the interior mesh screen directly passes through connector
It is connected with linkage ring flange, the outer mesh screen is connected by connector and connection column with linkage ring flange；It is set inside the motor
It is equipped with soft activator, Starting mode is soft start.
The connector is steel pipe；
The steel pipe of the interior mesh screen and outer mesh screen is on the same circumference of linkage ring flange；
The interior mesh screen is longer than outer mesh screen, and interior mesh screen is equipped with feed inlet, is equipped with outer cover on the outside of outer mesh screen, outer cover is equipped with
Corresponding discharge port；
The support wheel is placed in the two sides of rotary screen.
Due to implementing the above technology, rotary screen inclination installation directly drives the rotation of sieve using the rotation of linkage ring flange
Turn, without other structures in sieve, connection structure is steel pipe, while substantially reducing the weight of rotary screen, reduces friction, is saved
Can be environmentally friendly, time saving and energy saving, screening efficiency is high.Meanwhile smooth starting is realized using soft starting mode, production rotary screen is mostly diameter
Within Φ 1.6m, with being continuously increased of coal production scale, the requirement to the sieving capacity of rotary screen is also higher and higher, diameter
Also there is Φ 1.6m to increase to Φ 2.5m, power also and there is original 11KW to increase to 30KW, directly initiate and cannot expire with reduced-voltage starting
The demand of sufficient equipment even running, high instantaneous torque damage gear and shaft coupling will not be generated by reducing starting current, and increasing makes
Use the service life.
Detailed description of the invention:
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Fig. 1 is a kind of structural schematic diagram of soft start rotary screen.
Legend: 1, rack, 2, deceleration device, 3, interior mesh screen, 4, outer mesh screen, 5, connector, 6, connection column, 7, main shaft, 8,
Driving belt, 9, motor, 10, discharge port, 11, feed inlet, 12, support wheel, 13, linkage ring flange.
Specific embodiment:
The utility model is not limited by following embodiments, can determine specific reality according to technical solution and actual conditions
Apply mode.
As shown in Figure 1, a kind of soft start rotary screen specifically includes that rack 1, be mounted on rotary screen in rack 1, motor 9,
Deceleration device 2, and it is mounted on the support wheel 12 of 1 other side of rack, it is characterised in that: the motor 9, deceleration device 2 and roller
The linkage ring flange 13 sieved in live spindle 7 is connected, and the rotary screen includes interior mesh screen 3 and outer mesh screen 4, and the interior mesh screen 3 is straight
It connected connector 5 to be connected with linkage ring flange 13, the outer mesh screen 4 passes through connector 5 and connection column 6 and linkage ring flange 13
It is connected；
The motor 9 is internally provided with soft activator (not shown in FIG.), and Starting mode is soft start.
The connector 5 is steel pipe；
The connector 5 of the interior mesh screen 3 and outer mesh screen 4 is on the same circumference of linkage ring flange 13；
The interior mesh screen 3 is longer than outer mesh screen 4, and interior mesh screen 3 is equipped with feed inlet 11, is equipped with outer cover, outer cover on the outside of outer mesh screen 4
It is equipped with corresponding discharge port 10；
The support wheel 12 is placed in the two sides of rotary screen.
Due to implementing the above technology, rotary screen inclination installation, motor 9 drives linkage ring flange 13 by driving belt 8
Rotation, and then the rotation of sieve is directly driven, without other structures in sieve, connector 5 is steel pipe, makes the weight of rotary screen significantly
While reduction, reduce friction, energy conservation and environmental protection is time saving and energy saving, and screening efficiency is high.It is smoothly opened using soft starting mode realization
Dynamic, instead of reduced-voltage starting, high instantaneous torque damage gear and shaft coupling will not be generated by reducing starting current.
