Problems solved by technology

Several tons of mineral powder blockage not only waste a lot of manpower and material resources to clean up, but also make the sky full of ash, pollute the surrounding environment, and delay production
The blockage needs to be cleared for more than 4 hours at a time before it can be unblocked, which will delay the delivery for 4 hours, and then make the finished product inventory full and cause the production to be stopped for 4 hours, causing great losses

Embodiment 1

[0023] This embodiment provides a wharf steel silo feeding flow monitoring system, its structure schematic diagram is as follows figure 1 As shown, including weighing instrument, PLC control cabinet and pneumatic switch valve.

[0024] The weighing instrument is connected with the PLC control cabinet to monitor the mineral powder weighing signal stored in the steel warehouse, and convert the weighing signal into a 4~20 mA current signal and send it to the PLC control cabinet.

[0025] The PLC control cabinet is connected with the pneumatic on-off valve to control the closing of the pneumatic on-off valve and stop feeding.

[0026] The PLC control cabinet includes a pulse detector, a weight comparator and a picture alarm. The pulse detector receives the 4-20 mA current signal transmitted by the weighing instrument to detect the instantaneous weight of the steel bin, and transmits the weight to the weight comparator; The weight comparator calculates the feeding amount of the st...

Abstract

The invention discloses a wharf steel silo loading flow monitoring system which comprises a weighing instrument, a programmable logic controller (PLC) control cabinet and a pneumatic switch valve. The weighting instrument is connected with the PLC control cabinet and used for monitoring the weight of mineral powder stored in a steel silo, converting weighing signals to current signals and transmitting the current signals to the PLC control cabinet. The PLC control cabinet is connected with the pneumatic switch valve and used for controlling the pneumatic switch valve to be closed to stop loading. Simultaneously, the invention further discloses a wharf steel silo loading flow monitoring method. By adopting the wharf steel silo loading flow monitoring system and method, the problem of easiness in material blocking during wharf steel silo loading is solved, a large quantity of manpower and material resources are saved, income of two millions of RMB is increased per year, and environment pollution caused by mineral powder flying during material cleaning is reduced.

Description

technical field [0001] The present invention relates to a flow monitoring system and method thereof, more specifically, to a wharf steel bin feeding flow monitoring system and a monitoring method thereof. Background technique [0002] The slag powder factory adopts the chute conveying method when loading the steel silo, and the chute is often blocked during loading, with an average of three times a month. Several tons of slag powder blockage not only waste a lot of manpower and material resources to clean up, but also make the sky full of ash, pollute the surrounding environment, and also delay production. The blockage needs to be cleared for more than 4 hours at a time before it can be unblocked, which delays the delivery for 4 hours, and then makes the finished product inventory full and the production is forced to stop for 4 hours, causing great losses. The most fundamental reason for the blockage is that the flow of mineral powder into the warehouse cannot be monitored....
