In order to make mass transport in the feed hopper 21 to diverse location, the Pneumatic conveying pipeline 3 of this preferred embodiment is provided with distributing box 6, in the Pneumatic conveying pipeline branch of being drawn by distributing box 6 pressure pipe 46 equipressure detected transmission devices can be set also.
The exit of a branch of Pneumatic conveying pipeline 3 is provided with the not shown signal wire (SW) between the two of the conveyor trip switch valve 5(that is connected in controller 3), the exit of this branch can also be provided with temperature measuring equipment, with the indication blocked state.
This preferred embodiment can mainly carry out three kinds of workflows: transportation work flow process, automatically tackling blockage workflow, pipe choking indication flow process.
The transportation work flow process is: carry switch valve 14 to open, and feeder 22 operations, the pressurized air that derives from high-pressure air source 11 enters mixer 23 after becoming the low-pressure delivery air after reducing valve 16 decompressions; The convey materials that derives from feed hopper 21 enters mixer 23 through feeder 22; Low-pressure delivery air and convey materials are mixed in mixer 23 that gas-solid two phase materials are laggard goes into Pneumatic conveying pipeline 3, after distributing box 6 to being transported to destination locations.
For a certain reason, convey materials is deposited on certain connecting bend place becomes the obstruction material, cause being arranged in that delivery pressure detector after the reducing valve 16 is higher than a certain setting value or abnormal data appears in some pressure pipe 46, the transportation work flow process stops, the automatically tackling blockage workflow starts, be specially: feeder 22 is out of service, carry switch valve 14 to close, unimpeded switch valve 13 is opened, the unimpeded pressurized air that derives from high-pressure air source 11 enters Pneumatic conveying pipeline 3 via unimpeded high pressure gas source capsule 12, because the unimpeded pressurized air reduces pressure without reducing valve, its pressure is higher than the pressure of low-pressure delivery air, utilizes the unimpeded pressurized air that the obstruction material in pipe choking zone is delivered to destination locations.Delivery pressure detector force value is lower than a certain setting value, and the automatically tackling blockage workflow stops, and unimpeded switch valve 13 is closed, and carries switch valve 14 to open, feeder 22 operations.
Stopping up the indication flow process is: after unimpeded switch valve 13 is opened, the force value of delivery pressure detector is higher than the instruction time of setting value or the abnormal data of some pressure pipe 46 collections surpasses certain hour greater than setting value, stop up the indication flow startup, the difference of the force value of adjacent two pressure detectors 46 is the pipe choking zone greater than the pipeline section of a certain setting value, unimpeded switch valve 13 is closed, conveyor trip switch valve 5 cuts out, and this preferred embodiment enters the settlement of accident state, waits for the operating personal processing.
In sum, operation sequential by real-time collection pressure data and change related valve, when the air-transport system that the utility model provides takes place to stop up when Pneumatic conveying pipeline, can clearly indicate the concrete zone of pipe choking, for searching with the solution of fault of pipe choking position saved the plenty of time, and can carry out the unimpeded operation at initial stage automatically.This shows, the utlity model has the advantage of accurately knowing blocking position and automatically tackling blockage, can be beneficial to the operation of enterprise's high-efficiency and economic for enterprise operation saving a large amount of time cost and material cost.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all is a casehistory, is not only.All in the utility model scope or the change that is being equal in the scope of the present utility model all be included in the utility model.
