Fully automatic bucket-cleaning plant

InactiveCN101658850AHigh speedHollow article cleaningWork statusEngineering
The invention relates to a fully automatic bucket-cleaning plant mainly comprising a bucket-clamping device, a cleaning device, a power rotation part, a conveying part and the like, wherein the bucket-clamping device is provided with a pair of bucket-clamping pincers, and the bucket-clamping pincers firmly clamp a bucket under the suction of an electromagnetic valve. A rack in the electromagneticvalve drags a gear to enable the bucket-clamping pincers to rise to form an angle of 90 degrees with the electromagnetic valve. The mouth of the bucket is aligned to a cleaner, and a cylinder intake lever enables the cleaner to enter the bucket and to be opened in the bucket to carry out cleaning operation. The lever is wrenched to grip a gear ring and moves forward; a rotary table rotates once every 3 seconds, and the rotary table can rotate by 1 / 6 of the gear ring each time. Under the action of two worm wheels, the rotating speed per minute of the rotary table and the gear ring is reduced to200 rounds; when the rotary table rotates once, the bucket is rotated to the position of a conveyor, the lever rolls off the cylinder after the cleaning is completed to convey the bucket above a conveyer belt; the gear rotates outwards to put down the bucket-clamping pincers, a spring pushes a screw out to enable the screw to rotate 180 degrees, and the mouth of the bucket is downwards aligned tothe bucket pit of the conveyer belt, under the action of the spring, the bucket-clamping device puts down the bucket, and at the time, a switch bounces, enabling the electromagnetic valve to be powered on, and then the screw rotates 180 degrees so as to enable the bucket-clamping device to be restored to the original working state.

Method for optimizing PEMFC output performance based on frequency secant angle method

InactiveCN107391817AImprove output performanceOvercoming the large hysteresisElectrical testingDesign optimisation/simulationHysteresisInternal resistance
The invention discloses a method for optimizing fuel cell performance based on frequency and a secant angle. The method comprises the steps that in the working condition of the optimal temperature and humidity at which the total internal resistance Rstack of a PEMFC is minimal, the internal resistance of each galvanic pile segment at the moment is measured, and the ideal high-frequency corner frequency f<optimal> and ideal secant angle alpha<optimal> of different electric current densities are acquired correspondingly; with the f<optimal> and the alpha<optimal> as optimization indexes, focusing on the galvanic piles in any working condition, it is only necessary to emit two frequency signals of the highest frequency (20 KHz) and the ideal corner frequency f<optimal> to monitor the current alpha angle, and through uninterrupted adjustment of relevant control variables, the current alpha angle is changed and tends toward the optimal angle alpha<optimal>, so that the galvanic piles are adjusted to the optimal working state. According to the method, improvement is conducted on traditional EIS methods, and the total internal resistance Rstack is quickly calculated by means of a simultaneous equation solution method; not only is optimization of the galvanic pile output performance of the PEMFC achieved from the internal resistance angle, but also the defects that by means of the traditional EIS methods, the hysteresis is large and real-time detection cannot be conducted are overcome, and operation is simpler and the optimization performance is better compared with traditional methods.
