Description
Technical field
The present invention relates to hazardous waste fume treatment servicing unit, more particularly to a kind of powder feeding system of accurate broken arch
And its powder machine.
Background technology
It is used to handle flue gas, it is necessary to add calcium hydroxide, activated carbon etc. during dangerous waste incineration device fume treatment
The pollutant such as middle sulfur dioxide and heavy metal.Powder such as calcium hydroxide, activated carbon etc. are added by feed bin, due to the leakage of feed bin bottom
Often there is being formed arch bridge and not discharged or discharge situation about having some setbacks in bucket type structure.
Publication No. is CN106185082A Chinese patent《Powder machinery broken arch automatic and accurate throwing device》, disclose
A kind of throwing device, including disk feeder, the feed bin above disk feeder, disk feeder top linkage have
In the one broken arch week inside feed bin, the powder in feed bin is stirred by the flexure strip on broken arch axle, and then destroy material
Arch bridge in storehouse.
But the feed bin is arranged in frame by Weighing module in this scenario, is had a try by Weighing module and detect powder
The situation that feeds intake, and then control the power output of feed motor, and then realize the purpose that accurately feeds intake.
But when broken arch axle rotates stirring in feed bin, flexure strip directly can cause to press to the powder in feed bin, enter
And the data on Weighing module are caused to change；Simultaneously because the powder distributed architecture in feed bin can change in real time, thus directly
Connecing causes the pressure value between broken arch axle and powder to change so that the upper data of Weighing module also can real-time change, finally
Influence the dosage of powder machine.
The content of the invention
It is an object of the invention to provide a kind of basis situation of feeding intake Automatic Arch and not to interfere with the accurate of dosage
The powder feeding system of broken arch.
The present invention above-mentioned technical purpose technical scheme is that：A kind of powder of accurate broken arch supplies
Material system, including frame, batch charger and the feed bin above the batch charger, it is provided with the feed bin positioned at described
Broken arch axle in feed bin and the output motor for driving the broken arch axle；
Also include being arranged in the Weighing module in the frame, and be used to collect the Weighing module described within each minute
The monitoring module of the monitoring data of the inventory of feed bin,
For receive the monitoring data in the monitoring module comparison module,
By the contrast signal of the comparison module, and then the output motor is controlled to drive the rotation of the broken arch axle and described
The control module of batch charger operation；
The comparison module includes offline a reference value, if monitoring data is less than offline a reference value, the comparison module output pair
Than signal, the output motor is controlled to rotate to complete the control module to start the control module, the batch charger
It is out of service.
By using above-mentioned technical proposal, monitored by monitoring module in the Weighing module in frame to powder blanking feelings
Condition, produce monitoring data；Then the correction data that each minute is monitored is submitted in comparison module by monitoring module, led to
Cross compared with the offline a reference value in comparison module, when monitoring data is less than the offline a reference value, control module control
Batch charger is out of service, while controls output motor driving broken arch axle to be rotated, and then eliminates the arch that feed bin lower end is formed
Bridge so that feed bin being capable of normal blanking.After broken arch is completed in feed bin, control module output motor out of service, startup feeds intake
Machine continues to feed intake, and compared to prior art, feed bin can be persistently fed under normal circumstances；It is and broken when being completed in broken arch axle
During arch, broken arch axle is out of service, avoids the inventory of the shown powder of the broken arch systematic influence Weighing module, Jin Ershi
The purpose now precisely to feed intake.
The further setting of the present invention is：Also include the time block for being used to set the mixing time of the broken arch axle；Institute
When stating the mixing time of broken arch axle and reaching default mixing time, the control module stops the output motor and rotated, and starts institute
