Description
Technical field
The present invention relates to a kind of automated system, particularly relate to the automatic control system of conveying bagasse in a kind of sugar refinery except marrow pan feeding.
Background technology
Bagasse is the principal by product of cane sugar manufacture industry, and be the stringiness residue of sugarcane through the broken cane stalk with extracting after sugarcane juice, belonging to the one in agricultural solid residue, is also a kind of renewable resource.Process in the middle of operation the sugarcane of torrid areas and subtropical zone, probably can produce every year about more than the bagasse of 1,000,000 tons.In the composition of bagasse, cellulose is 32%-48%, hemicellulose 19%-24%, lignin 23%-32%, ash content about 4%.Bagasse, except being used as fuel power generation function, can also being used for papermaking, wood-based plate processed, activated charcoal, dietary fiber, thermoplastics, biodiesel and producing ethanol, xylitol, rich protein-contg biological feedstuff, enzyme, amino acid etc.
The bagasse that bagasse mainly uses fiber longer when being used for the product such as papermaking, wood-based plate processed, production activated charcoal, dietary fiber, thermoplastics, sugarcane marrow needs to remove, in marrow process, adopt vibrations screw machine to carry out at present, bottom screw machine, screen cloth is installed, sugarcane marrow is separated from screen cloth by vibrations by bagasse in motion process, and sugarcane marrow can as the raw material of feed or edible fungi, and sugar refinery major part is used for burning boiler and produces steam and boil sugar and generating.
Bagasse is a kind of biomaterial of fiber quality, and compared with unclassified stores (as grain, mineral etc.), it has the features such as little, the easy blocking of density, dust be large.Because the shear resistant of bagasse material is very high, adhesive tape, operationally once meet with obstruction, is easy to formation bagasse group, stops that bagasse below continues to run, and under stress can be more and more tighter, even suppresses all to be difficult to labor cleaning after stopping equipment and to open.Bagasse induction system is the important component part of cane sugar factory boiler power system, once go wrong, boiler output will be caused to decline rapidly, if do not recovered at short notice, complete plant shutdown finally can be caused even to have an accident.
Sugar refinery many at present all also exists such problem at bagasse except in marrow:
1, the pan feeding sluice gate of bagasse uses manual control, and switch sluice gate is required great effort, slightly misoperation or not in time, namely causes depithing machine and jumps system, blocking, burns motor and even fill in slag and stop squeezing accident;
2, the unload material control of bagasse is mainly by manpower manual operation, discharging personnel due to needs successively disclose material cause work difficulty and intensity excessive, affect depithing machine and removes the efficiency of marrow;
3, owing to being manual operation, blanking is often excessive or too small, and cause feed unstable, make depithing machine operation energy consumption high, treatment capacity is little, and failure rate is high, and maintenance cost is large, is unfavorable for safety in production and saves energy and reduce the cost.
Summary of the invention
For solving the problem, the object of the invention is the volume increase based on sugar refinery and remove the large demand of marrow treatment capacity to bagasse, provide during a kind of format high throughput and do not block, bagasse conveying is steady, blanking is even, the boiling type depithing machine pan feeding automatic control system reducing human resources and raise the efficiency.
Technical scheme provided by the invention is:
Boiling type depithing machine pan feeding automatic control system, it is characterized in that, at the motor of boiling type depithing machine, current sensor is installed, the bagasse blanking port place of the bagasse carrier before bagasse enters boiling type depithing machine is provided with blanking baffle plate, baffle plate is driven by electric drive hydraulic thruster, above the helical-blade of bagasse blanking port and boiling type depithing machine, surveillance is installed, at operation room, PLC is installed, connect display touch-screen, the current value signals of boiling type depithing machine motor is passed to PLC by current sensor, by the process of PLC built-in command, output signal controls the running of electric drive hydraulic thruster motor, driving electric drive hydraulic thruster works, the open degree of blanking baffle plate is regulated simultaneously, thus reach the amount controlling bagasse blanking port bagasse, ensure that boiling type depithing machine maintains and normally work is turned over to the throwing of breaing up of bagasse, described display touch-screen and surveillance are connected installing surveillance above the helical-blade of bagasse blanking port and boiling type depithing machine, understand the conveying of bagasse and the duty of boiling type depithing machine to operating personnel.
PLC is also connected with the operated motor of bagasse carrier, automatically controls the rotating speed of the operated motor of bagasse carrier when boiling type depithing machine is operated at full capacity or broken down.
Bagasse carrier is also provided with controllable register, controls the operational throughput of bagasse at bagasse carrier.And can prevent bagasse from forming a bagasse group, make bagasse can the conveying of uniform and stable.
The communication technology adopts serial communication bus.Take PLC as core, host computer is the control system monitoring body in real time.By host computer, the read-write of plc data is monitored, realize the collection of field data, the robotization of transmission and scheduling and informationization.
PLC has manual control and automatically controls two kinds of modes.Operating personnel can change control model according to the actual conditions at scene.
Display touch-screen can monitor PLC operation conditions, and sends steering order to PLC.Display touch-screen shows service data in real time and shows as running current, equipment state, failure logging etc. to be kept in controller and to transfer to main frame, achieves the Based Intelligent Control to system and monitoring, considerably increases the dirigibility of Systematical control.Display touch-screen receives touch information from touch point detection device, and converts it to contact coordinate, then gives CPU, and it can receive order that CPU sends simultaneously and be performed.
Actual gain of the present invention is:
1, native system installs easy-to-connect, operates steadily;
2, native system is provided with bagasse controllable register on bagasse carrier, reduces the probability of bagasse blocking;
