A conveyor is driven by multiple driving devices. Each driving device is mainly composed of an intelligent control device (1), an electromotor (2), a hydraulic coupler (3), a speed reducer (4), an overrun clutch (5) and a transmission drum (6), wherein all the parts are in interlink with one another in sequence and can be in transmission operation in sequence when the conveyor is started. According to the belt conveyor reduction motor energy saving system based on intelligent control, the currents of the electromotors are detected to calculate the real-time load of the conveyor, the number of the driving electromotors is increased or decreased according to the load, and therefore the purposes of saving energy and reducing consumption are achieved.
Description
Technical field
The utility model belongs to the harbour machinery technical field, and a kind of belt conveyer based on Based Intelligent Control that especially is applicable to harbour many motor driven belts of bulk storage yard formula conveyer energy-saving run subtracts electrical machine energy-saving system and control method thereof.
Background technology
The bulk cargo terminals stockyards such as harbour coal, ore are moved under the underloading of being everlasting with belt conveyer, and the needed transmission power of load-transfer device is lower, serious " low load with strong power " phenomenon occurs, causes its motor consumption higher, and the system power factor is lower.At present the actv. energy-saving run technology for belt conveyer is not all implemented at the most harbours of China, and the only a few harbour is adopted and subtracted power supply that the electrical machine energy-saving running technology also just directly cuts off electrical motor and reach and subtract motor operation purpose.And after electric motor circuit breaking, electrical motor, fluid coupling, retarder, coupler etc. can be with the passive idle running of load-transfer device, and this idle running mode has been aggravated the wearing and tearing of various drive disk assemblies on the one hand, has increased on the other hand extra running resistance.
Therefore, to subtract the electrical machine energy-saving system be very necessary to a kind of brand-new many motor driven belts formula conveyer of design.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned deficiency, a kind of Real-time Load size that calculates conveyer by the size that detects motor current is provided, control the increase and decrease of driving motor quantity according to payload, thereby the formula of the many motor driven belts based on the intelligent controller conveyer that reaches energy-saving and cost-reducing purpose subtracts the electrical machine energy-saving system.
To achieve these goals, the utility model is achieved through the following technical solutions:
a kind of belt conveyer based on Based Intelligent Control subtracts the electrical machine energy-saving system, conveyer is driven by many covers actuating device, every cover actuating device is mainly by intelligence controlling device (1), electrical motor (2), fluid coupling (3), retarder (4), overriding clutch (5) and driving drum (6) form, wherein: the digital electronic ammeter in intelligence controlling device (1) is connected with the current transformer of electrical motor (2), electrical motor (2), fluid coupling (3), retarder (4), overriding clutch (5) is connected 6 with driving drum) connection of order axle, overriding clutch (5) is connected on the driving drum (6) of belt conveyer, after conveyer started, electrical motor (2) place in operation, arrived transmission of power on driving drum (6) the points driving for belt conveyor running by fluid coupling (3), retarder (4), overriding clutch (5), when intelligence controlling device (1) sends while subtracting the electric machine control instruction, wherein the electrical motor (2) of a cover actuating device is out of service, and overriding clutch (5) separates simultaneously, and fluid coupling (3), retarder (4) shut down immediately.
, owing to having adopted technique scheme, the utlity model has following advantage and effect:
1, the overriding clutch of the utility model employing, make the action that reduces electrical motor at control setup, after certain electrical motor is cut off, the fluid coupling, the retarder that coordinate with this electrical motor is also shut down, thereby protected the parts such as electrical motor, retarder to avoid effect of attrition;
2, the utility model is when intelligence controlling device control electrical motor is in driving condition, and overriding clutch plays coupler effect, transferring power; When intelligence control system control electric motor circuit breaking subtracted the motor operation, package unit stopped passive transport automatically;
3, the utility model control setup is comparatively advanced, can realize that overall process, all the period of time to belt conveyer controlled automatically; Simultaneously can reduce the wearing and tearing of drive disk assembly and the resistance loss of system, improve the service life of electrical motor, fluid coupling and retarder;
4, the utility model calculates the Real-time Load size of conveyer by the size that detects motor current, controls the increase and decrease of driving motor quantity according to payload, thereby reaches energy-saving and cost-reducing purpose.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is intelligence controlling device schematic diagram of the present utility model;
Fig. 3 is workflow diagram of the present utility model.
The specific embodiment
by Fig. 1, Fig. 2 illustrates, a kind of formula of many motor driven belts based on Based Intelligent Control conveyer subtracts the electrical machine energy-saving system, conveyer is driven by many covers actuating device, every cover actuating device is by intelligence controlling device 1, electrical motor 2, fluid coupling 3, retarder 4, overriding clutch 5 and driving drum 6 form, wherein: the digital electronic ammeter of intelligence controlling device 1 Inner Front End is connected with the current transformer of electrical motor 2, electrical motor 2, fluid coupling 3, retarder 4, overriding clutch 5 is connected the order axle and is connected with driving drum, overriding clutch 5 is connected on the driving drum 6 of belt conveyer, after conveyer starts, electrical motor 2 place in operations, by fluid coupling 3, retarder 4, overriding clutch 5 with transmission of power to driving drum 6, make while subtracting motor action when intelligence controlling device 1, electrical motor 2 is out of service, and overriding clutch 5 separates simultaneously, and fluid coupling 3, retarder 4 shut down immediately.
When conveyer starts,, because the short time rating of needs is larger, need the whole place in operations of electrical motor 2; At this moment, intelligence controlling device 1 is ignored current data,, through t1 left and right second time delays (the t1 size is different and different according to conveyer, usually chooses between second to 400 seconds), after machine smooth running to be conveyed, then according to current value, controls; After current value that amperemeter/ammtr will record is uploaded to the acquisition module of intelligence controlling device 1, compared with setting current value A1 by 1 pair of measured value of intelligence controlling device, if measured value is less than setting value A1, illustrate that the electrical motor degree of utilization is lower, sent and subtracted motor instruction by intelligence controlling device 1 this moment, electrical motor 2 is out of service, and overriding clutch 5 separates, and the fluid coupling 3, the retarder 4 that are connected with this motor shut down simultaneously; If measured value is greater than setting value A1, the electrical motor 2 state operation of remaining stationary; In subtracting motor operation course, amperemeter/ammtr detects the current value of electrical motor 2 at any time, and when due to the load increase, causing current value to increase to greater than setting value A2, the motor that is cut will put into operation again.
Repeatedly increase and decrease the endless loop of motor for fear of the belt conveyer trip, current setting value A2 needs greater than A1.
