Problems solved by technology

The advantage of this method is that no one needs to control the cantilever rotation speed in real time. In the case of a large material pile, the reclaiming flow rate can be kept above a certain value. The disadvantage is that it is difficult to establish a relationship between the cantilever revolving speed and the instantaneous reclaiming flow rate. , and if the stockpile is relatively small and there are many corners, the instantaneous retrieving flow rate will be small within a certain period of time, which seriously affects the operating efficiency

Embodiment Construction

[0012] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0013] The invention provides a method for controlling the reclaiming flow rate of a reclaimer, such as figure 1 As shown, the method includes the following steps:

[0014] Step S1. Obtain the actual instantaneous material flow rate according to the bucket wheel current or bucket wheel pressure;

[0015] Step S2. Comparing the acquired actual instantaneous material flow rate with the target instantaneous material flow rate; and

[0016] Step S3, setting the cantilever rotation speed of the reclaimer according to the comparison result.

[0017] Commonly used bucket wheel reclaimers can generally include motor direct start type bucket wheel reclaimers and hydra...

Abstract

The invention belongs to the engineering control field and discloses a reclaimer reclaiming flow control method and device. The method includes the following steps that: actual instantaneous reclaiming flow is obtained according to bucket-wheel current or bucket-wheel pressure; the obtained actual instantaneous reclaiming flow is compared with target instantaneous reclaiming flow; and the cantilever rotation speed of a reclaimer is obtained according to a comparison result. With the reclaimer reclaiming flow control method and device of the invention adopted, the workload of a driver can be reduced, and reclaiming flow can be kept stable, and work efficiency can be improved.

Description

technical field [0001] The invention relates to the field of engineering control, in particular to a method and device for controlling the reclaiming flow rate of a reclaimer. Background technique [0002] When the bucket wheel reclaimer is reclaiming, the cantilever rotation speed directly affects the instantaneous reclaiming flow rate (the unit is usually tons / hour or T / H). In the manual reclaiming mode, the driver controls the cantilever rotation speed by turning the operating handle, and increases or decreases the cantilever rotation speed by observing the real-time video system of the material on the cantilever belt, bucket wheel current or bucket wheel pressure, belt scale data, etc. In order to achieve the stability of the reclaiming flow as much as possible. Its advantages are stable retrieving flow rate and flexible reversing of retrieving boundaries, but its disadvantages are high requirements for operator skills and heavy labor load. [0003] In the traditional ...
