Description
Technical field
The present invention relates to the gravity settling separation concentrator drive transmission that a kind of defecator is used.
Background technology
Concentrator is to be applied to multiple industry to realize that the liquid-solid phase mixture of homogeneous phase carries out the capital equipment that gravity is asked sedimentation separation; Be that a kind of volume is big, power is little, a kind of production equipment of the slow-speed of revolution, high pulling torque; Mostly for running without interruption for a long time; Equipment safety operation is required height, and drive unit is the main composition part of concentrator.Original Thickener Drive drives for using a reductor to drive a big worm-gear speed reducer mostly; Drive path: motor → reductor → linked transmission → worm-gear speed reducer → worm gear drives output shaft output torque; Because of worm-gear speed reducer itself with regard to shortcomings such as efficient low, caloric value height; The total transmission efficiency of whole drive unit is about 50～60%, and the idle work of waste is more when high-power, and operation cost is higher.Along with the concentrator specification that drives and the difference of sedimentation medium, have the more output of high pulling torque; And the power source that concentrator uses is asynchronous motor; Difference in the production process of middle transmission; Self-locking during the worm decelerating machine transmission in addition, input and output can't be reversible; If when using a plurality of reductors to drive a worm decelerating machine, can can't normally move, even have the danger that damages worm decelerating machine because of stationary problem.When needs are exported than high pulling torque; The corresponding increase of final stage worm-gear speed reducer specifications and models; Consequently whole drive unit is bulky, weight is excessive, and the consequence of directly bringing is that the bridge support designing requirement of supporting driving device is high, consumptive material is many, cost is high; In the working service, repair difficulty after worm gear weares and teares in the future, replacement cost is higher.The Chinese patent 200620124910.1 that our company was authorized in 2007 discloses a kind of Thickener Drive; Constitute gear unit by power source, reductor, transmission device, output shaft etc.; Pinion that is provided with on the output shaft of described Thickener Drive by the gear unit more than two and the engagement of the gear wheel of pivoting support; Described pivoting support gear wheel and connecting plate Joint are connected with total output shaft on the described connecting plate.This Thickener Drive compact conformation, volume is little, and is in light weight, and moment of torsion is big, transmits reliably, and efficient is big, and is easy to maintenance.
Concentrator is when maximizing, and moment of torsion needs very big, and traditional concentrator adopts smooth bar or pipe, can need very major diameter and wall thickness, and difficulty is very big in the actual fabrication process, and own wt is very heavy.When the needs concentrator realizes that dense underflow etc. requires, often adopt the very high concentrator pond body of straight section height, this kind concentrator is a deep wimble thickener, common peripheral transmission concentrator because its design feature can not use on the very high concentrator pond body of straight section height.
Summary of the invention
The present invention overcomes that peripheral transmission concentrator can not use the defective on the very high concentrator pond body of straight section height in the prior art; A kind of internal gear transmission Thickener Drive is provided; Its compact conformation; Working stability, reliable, applied widely is convenient to realize the maximization of center transmission concentrator.
The technical scheme that the present invention takes is:
Internal gear transmission Thickener Drive; Constitute gear unit by power source, reductor, transmission device, output shaft etc.; The output shaft of described gear unit connects with spline or shaft coupling with reductor, engagement in the pinion that is provided with on the output shaft of described gear unit and the gear wheel of pivoting support.
Described gear unit is through secondary or the reductor deceleration transmission more than the secondary, and described reductor is cycloid or planet-gear speed reducer.
Described gear unit is 2-4
Also be provided with the electronic torque sensor between the reductor more than described secondary or the secondary.
Internal gear transmission Thickener Drive of the present invention is driven by 1～4 electrical power source; Each power source drives first class reducer with synchronous rotational speed, through torque sensor power is delivered to the 2-level reducer of each large speed ratio, after 2-level reducer slows down; Give output shaft and pinion with transmission of power again; Output shaft adopts with reductor and divides body structure to connect with spline or shaft coupling, and pinion drives to mesh in the gear wheel on the pivoting support and rotates described pivoting support gear wheel and connecting plate Joint; Again through with gear wheel be suspended on the connecting plate that the steel square center cage main shaft under the drive unit links together; The cage main shaft is rotated with gear wheel, drive the concentrator rake arm that is fixed on the cage main shaft and rotate, to reach high pulling torque purpose at a slow speed.Between first class reducer and 2-level reducer, torque sensor is housed.Design superior torque sensing system; Can measure the resistance that this concentrator is born in real time in continuing rotation process; Through accurate instrument torque value is transformed into and transmits signal and be connected, thereby reach the purpose of automatic control, accurately control rake machine change in torque situation with the DCS system.Meet deadly condition and can in time take corresponding measure, reduce and shut down number of times.2-level reducer can be planet-gear speed reducer or cycloid speed reducer.
The present invention is applied on the center transmission concentrator that substitutes peripheral transmission concentrator; Upwards stretch out a circular central column at the concentrator pool center; Be used for the support drive device, the circular central column need bear the weight of drive unit and the reaction torsion of drive unit output torque.
Beneficial effect of the present invention: output shaft and reductor adopt and divide body structure to connect with spline or shaft coupling, and engagement has characteristics simple and compact for structure in the gear wheel of pinion and pivoting support, realized drive unit in static outside rotation.Working stability, reliable, applied widely.Because this kind drive unit has its unique drive form; Be suspended on steel square center cage main shaft under the drive unit can do very firmly and length very long; When making the big rigidity requirement of main shaft output torque very big; Strengthening the square center cage main shaft length of side is that profile strengthens, and institute is so that the maximization of realization center transmission concentrator.When the needs concentrator realizes that dense underflow etc. requires, add rectangle center tank cage main shaft, can be applied on the large-scale deep wimble thickener.
