Problems solved by technology

The advantage of this method is that there is no need for real-time control of the rotation speed by humans. In the case of a relatively large material stockpile, the reclaiming flow rate can be kept above a certain value. The disadvantage is that it is difficult to establish a relationship between the revolving speed and the reclaiming flow rate requirements, and If the stockpile is relatively small and there are many corners, the retrieving flow rate will be small within a certain period of time, which will seriously affect the operation efficiency

Embodiment ( 1

[0029] see figure 1 A schematic flow chart of an embodiment of a method for controlling the material flow rate of a bucket-wheel stacker-reclaimer according to the present invention is shown.

[0030] 101: Obtain the bucket wheel current value or the bucket wheel pressure value of the bucket wheel stacker-reclaimer.

[0031] In practical applications, because bucket wheel stackers and reclaimers with different drive types exist on the market, the information obtained is different. On the equipment driven by the motor bucket wheel, the material flow rate of the bucket wheel is positively related to the current of the bucket wheel motor, and on the equipment driven by the hydraulic motor, the material flow rate of the bucket wheel is positively related to the pressure value of the bucket wheel. The operator can determine the feeding flow rate of the bucket wheel according to the obtained bucket wheel current value or bucket wheel pressure value.

[0032] 102: Calculate the cur...

Embodiment ( 2

[0044] Corresponding to the above method, the present invention also discloses a device corresponding to the above method. see figure 2 A schematic structural view of a bucket-wheel stacker-reclaimer reclaiming flow control device according to the present invention is shown.

[0045] The device mainly includes: an information collection unit 1, and the information collection unit 1 is used to obtain a bucket wheel current value or a bucket wheel pressure value of the bucket wheel stacker-reclaimer.

[0046] A computing unit 2 connected to the information collection unit 1, the computing unit 2 is used to calculate the The current reclaim flow rate of the stacker-reclaimer.

[0047] An adjustment unit 3 connected to the calculation unit 2, the adjustment unit 3 is used to compare the preset target reclaiming flow rate with the current reclaiming flow rate, and adjust the cantilever rotation of the bucket wheel stacker-reclaimer according to the comparison result speed to ad...

Abstract

The invention provides a method and a device for controlling the reclaiming flow of a bucket wheel type stacker reclaimer. As the reclaiming flow of a bucket wheel type motor is positively related to a bucket wheel current value or a bucket wheel voltage value of the reclaimer, a current reclaiming flow of the reclaimer is obtained through the bucket wheel current value or the bucket wheel voltage value of the reclaimer. Furthermore, a target reclaiming flow is compared with the current reclaiming flow, and the rotating speed of a cantilever of the stacker reclaimer is adjusted through PI operation. As the reclaiming flow of the reclaimer is related to the rotating speed of the cantilever, control of the reclaiming flow can be achieved by adjusting the rotating speed of the cantilever, the reclaiming flow is maintained constant, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a method and device for controlling the reclaiming flow of a bucket-wheel stacker-reclaimer. Background technique [0002] The bucket wheel stacker and reclaimer is a rail-type loading and unloading machine that uses the bucket wheel to continuously reclaim materials and uses the belt conveyor on the machine to continuously stack materials. It is mainly composed of a bucket wheel mechanism, a cantilever slewing mechanism, a cantilever belt conveyor, a tail car, a pitching mechanism and a cart traveling mechanism. [0003] During the reclaiming operation, the cantilever rotation speed directly affects the reclaiming flow rate (tons / hour or T / H). In manual reclaiming mode, the driver controls the rotation speed of the cantilever through the rotary operation handle to achieve stable reclaiming flow as much as possible. However, this method requires high skill of the operator and h...
