The Intellectualized material feedway
Technical field
The utility model belongs to material strength transportation art, is specifically related to a kind of Intellectualized material feedway that is used for mass transport.
Background technology
It is a kind of technological process that replaces traditional mechanical transport material with the sealed type delivery duct that strength is carried, be widely used in industrial sectors such as pharmacy, food, plastics, cement, chemical industry, glass, generally be used in the operations such as storage, transportation, material feeding and metering of material.Carry for malleation commonly used, its utilization is installed in the blower fan or the air compressor of delivery system starting point, to be higher than atmospheric air feeds in the feeding device, after mixing of materials, it is gentle together in delivery pipe is delivered to the disconnector or bunker of terminal point to expect, air is discharged in the atmosphere after filtering, and material is stayed in separation or the bunker.It has, and technology arrangement is flexible, fed distance is long, takes up an area of advantages such as few, and in the mass transport field, especially the transportation art of powder has obtained to use comparatively widely.
Wind speed in the conveying pipeline must guarantee that material can carry reliably, also will consider the cost that moves simultaneously.Consumption of power almost is directly proportional with the cube of wind speed, and wind speed is too high, and consumption of power is excessive; Wind speed is low excessively, and is little to the comformability of mass transport quantitative changeization, and material takes place to stop up or fall job insecurity easily.So should make the operational throughput of wind speed and material reach best coupling guarantee to take low wind speed under the reliable and stable prerequisite of transportation work as far as possible.To avoid occurring following situation: the material to easy conveying has wind not have the short situation of powder, fed distance, causes the waste of source of the gas energy consumption; To the material of difficulty conveying, the situation that fed distance is long, the source of the gas deficiency results in blockage.
Novel content
The purpose of this utility model provides a kind of Intellectualized material feedway, helps realizing the optimum matching of wind speed and mass transport amount, avoids the waste of power consumption and the latch up phenomenon of pipeline.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of Intellectualized material feedway, comprise and carry source of the gas, feeding device, delivery duct and reception bucket, pressure transformer is installed on delivery duct, its pressure signal input PLC control setup, import at described conveying source of the gas is equipped with pressure regulating valve, feeding device drives and adopts variable-frequency motor, and described pressure regulating valve and variable-frequency motor control signal draw the control setup from PLC.
Further, the import of described conveying source of the gas is equipped with gas flow counter.
Especially, described conveying source of the gas is provided by roots blower.
Especially, described feeding device adopts rotary feeder.
Intellectualized material feedway described in the utility model, adopt the force value of pressure transformer dynamic measurement delivery duct, input PLC control setup, can be by the PLC control setup according to the rotating speed of the force value automatic compensation feeding device variable-frequency motor of setting and the pressure behind the pressure regulating valve, when line pressure exceeds setting range, adjust the frequency converter output speed, reduce the blanking amount; For heavy material, increase bleed pressure automatically, increase unit time tolerance; When line pressure is lower than setting range, adjust the frequency converter output speed, increase the blanking amount; For the material of light specific gravity, reduce bleed pressure automatically, reduce unit time tolerance.Can adjust delivery pressure and flow in real time, reduce greatly and carry power consumption, prevent to stop up, and can carry out the further metering and the monitoring of energy consumption by the gas flow counter of installing.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is an Intellectualized material transport conveyor constructions principle schematic described in the utility model.
Among the figure:
1, roots blower; 2, gas flow counter; 3, pressure regulating valve; 4, bag hose; 5, unpack bucket; 6, rotary feeder; 7, nozzle; 8, delivery duct; 9, pressure transformer; 10, PLC control setup; 11, receive bucket.
The specific embodiment
Fig. 1 has provided Intellectualized material transport conveyor constructions principle schematic described in the utility model, as shown in the figure, the source of the gas part of device for transporting objects is made up of roots blower 1 and annex thereof, link to each other with nozzle 7, the top of nozzle 7 is equipped with rotary feeder 6, with supporting the unpacking bucket 5 in addition and be used to the bag hose 4 that prevents that material from overflowing of rotary feeder 6, material can finally be delivered to by strength by delivery duct 8 and receive bucket 11 by unpacking after bucket 5 enters.
In order to realize the saving of power consumption, and the operational throughput that makes wind speed and material simultaneously reaches best coupling, guarantee to stop up in that delivery duct is unlikely, pressure transformer 9 is installed on delivery duct 8, its pressure signal input PLC control setup 10, in the import of carrying source of the gas pressure regulating valve 3 is installed, rotary feeder 6 drives and adopts variable-frequency motor, and pressure regulating valve 3 and variable-frequency motor control signal draw from PLC control setup 10.Can when delivery duct 8 internal pressures exceed setting range, adjust the frequency converter output speed by PLC control setup 10 according to the rotating speed of force value automatic compensation rotary feeder 6 variable-frequency motors of setting and the pressure of pressure regulating valve 3 back, reduce the blanking amount; For heavy material, increase bleed pressure automatically, increase unit time tolerance; When line pressure is lower than setting range, adjust the frequency converter output speed, increase the blanking amount; For the material of light specific gravity, reduce bleed pressure automatically, reduce unit time tolerance.Can adjust delivery pressure and flow in real time, reduce greatly and carry power consumption, prevent to stop up, and can carry out the further metering and the monitoring of energy consumption by the gas flow counter of installing 2.
Above-mentioned explanation is specifying at the feasible embodiment of the utility model; and this embodiment is not the claim of creating in order to restriction the utility model; allly do not break away from the equivalence that technical spirit that the utility model creates done and implement or change, for example adopt the embodiment of dissimilar control setups, different air feed feed-type all should be contained in the claimed claim of the application.
