Single tube spiral weighing feeder

Single tube spiral weighing feeder:
Single tube spiral weighing feeder is an automatic industrial equipment for real-time control and dynamic
measurement of various powdery materials. Its volume is small, and the transportation and metering can
be carried out uniformly in a single pipe, which not only saves space and cost, but also saves time to a certain
extent.

•   Weighing accuracy ：≤ 1%
•   Weighing range: 5 ~ 120 m ³/ h
•   Inclination： ≤ 20
•   Supporting power supply  ：Three phase 380V
•   operation mode ： continuity
•   Speed regulation range：  10:1

Product introduction:

Single tube spiral weighing feeder is an automatic industrial equipment for real-time control and dynamic
measurement of various powdery materials. Compared with the double tube spiral scale, its size is smaller,
and the conveying and metering can be carried out uniformly in a single tube. Although the equipment is
small, the skill is not small. Because it is suitable for conveying a variety of materials: pulverized coal, flour,
grain, chemical fertilizer, etc., it is a great artifact in the eyes of many industries such as agriculture,
environmental protection and food

 

Product features:

Exquisite structural design   The biggest feature is that metering and feeding are carried out at the same
time, which can be completed by only one screw. Convenient transportation, no space and cost saving

Current stabilizing technology is the core  The industry-leading steady flow technology is adopted to
fully ensure the smooth transportation of materials, not easy to arch, prevent material blockage, and ensure
the stability of actual use accuracy.

User friendly and easy to operate The operation interface of this equipment is very intuitive. Users can
manually insert parameters, and the daily maintenance is also simple and easy to operate

Instrument zero point traceable The instrument equipped with the screw scale has the function of automatic
zero tracking. The relevant weighing data can be protected in time, and the RS-485 communication interface can
also be configured, which can be centrally controlled by the industrial computer

 

working principle:

The material is transported from the feed port to the metering cutter connected below through the screw conveyor,
and the fully weighed weight of the metering screw is sent to the controller with a voltage signal proportional to the
weighing load through three tension sensors installed on the metering cutter, Together with the preset cutter speed
data (in case of double tube metering, the metering cutter operates at a constant speed to advance the material, that
is, the speed signal is the design value of the metering cutter).

At this time, the instantaneous flow and cumulative weight value are obtained from the weight and speed signals
throughcalculation. The spiral quantitative feeding scale control system compares the actual flow signal with the
set flow signal, and outputs the control signal to the frequency converter through PID adjustment to dynamically
adjust the speed of the feeding cutter, so as to realize quantitative feeding.
