Electronic Screw Scale Weighing Feeder for Cement Powder

1. Product introduction (also known as heavy screw feeder, electronic screw scale, weighing feeder, quantitative feeder)

The spiral weighing system is mainly composed of a steady flow feeding screw, a weighing bridge, a reduction motor, a weighing sensor, a speed sensor, a weighing control instrument and an electronic control system, etc. The weighing bridge is a lever type, and its lever fulcrum uses ears The shaft is not affected by corrosion and external factors on the measurement accuracy; the speed sensor is placed on the non-driving end of the spiral body.

2. Working principle:

The spiral weighing quantitative feeder is used for quantitative feeding of bulk materials. The feeding process is spiral continuous feeding. The material from the user's feeding bin or other feeding equipment is transported and the weight is detected by the weighing bridge. ; At the same time, the detection sensor spiral body installed at the end is used for speed detection; the detected weight signal and speed signal are sent to the weighing controller for calculus processing and the instantaneous flow rate of one ton per hour and the unit of ton are displayed. The cumulative amount.

3. Performance characteristics:

1. The feeding screw has a unique steady flow structure, the material powder sinks evenly on the entire feed inlet section, and it is not easy to form an arch and rinse.
2. Single spiral shaftless structure, stable material flow, no jamming. Real weight signal, higher measurement accuracy (optional)
3. The spiral blade is made of manganese steel/stainless steel material, which has strong wear resistance and corrosion resistance and long service life.
4. The spiral gap is small, which overcomes the problem of backwashing and avoids the adhesion of materials in the gap of the pipe wall.
5. Sealed structure to reduce dust flying.
6. The material inlet and outlet are soft connected, and the horizontal installation angle can be adjusted arbitrarily according to the site requirements.
7. Automatic measurement calibration coefficient, automatic measurement system zero.
8. Manually insert various parameters, and the operation can be switched manually/automatically.
9. With instrument self-diagnosis and computer networking functions.

4, the basic composition:

  Tension sensor is also called resistance strain sensor, which belongs to load cell series. It is a device that converts physical signal into measurable electrical signal output. It uses two tensile forces to transmit part of the force and contains force sensitive in its structure. The device and two tension transfer parts. The force-sensitive device contains a piezoelectric sheet, a piezoelectric sheet gasket, which contains a substrate part and an edge force-transmitting part. The tensile sensor is based on the principle that an elastic body (elastic element, sensitive beam) is elastically deformed under the action of external force. The resistance strain gauge (conversion element) attached to the other surface is also deformed. After the resistance strain gauge is deformed, its resistance value will change (increase or decrease), and then the resistance will be converted into electricity through the corresponding measurement circuit. Signals (voltage or current), thus completing the process of transforming external forces into electrical signals.
The counterweight is to maintain the balance of the spiral when conveying materials.
The weighing instrument is a microcomputer-based dynamic weighing instrument, which is specially used to connect the weighing with the speed sensor and the weighing sensor. It is processed by its powerful hardware and software to display continuous flow and weight information.
