Embodiment Construction

[0014] see figure 2 , image 3 , a combined process start-up method for a tape conveying system, which is to track the materials on the tape machine process, and track the head of the material during the normal material conveying process. The start sequence of the tape machine is consistent with the flow direction of the material, that is, reverse The first start, the start time of the tape machine is started according to the following formula,

[0015] T n =∑M(n-1)-K

[0016] In the formula: M is the full time of the tape machine, which refers to the time required for the material to go from the tail to the head of the tape machine, and K is the early start constant.

[0017] When the feeding equipment stops the feeding operation, the tail of the material is tracked during the material discharge process.

[0018] see figure 1 , Figure 4 , when the tape machine process is restarted after the material is stopped, the start sequence of the tape machine is opposite to the...

Abstract

The invention discloses a combined type flow path starting method of belt transmission system, which comprises the following steps: tracing the head of material on the belt flow path; making the starting sequence consistent with the flow direction of material to start by inversed-sequence; according to Tn=SigmaM(n-1)-K to start the belt machine (M is full-path time of belt machine; K is the advanced starting constant); Tracing the rear of material in the discharging course when the feeding equipment stops running. The invention switches the starting pattern at inversed-sequent and sequent pattern mutually, which improves the equipment utility and saves power.

Description

(1) Technical field [0001] The invention relates to a combined flow starting method of a belt conveying system. This method can be applied to industries that use belt conveyor systems to transport bulk materials, such as: metallurgy, mining, coal, ports, power plants and other enterprises. (2) Background technology [0002] Belt conveyors are often combined with multiple, or even dozens of, as a process, and the operation of conveying materials is carried out under the control of PLC. The current way to start such a process is that the start sequence is opposite to the material flow direction, that is, "sequential start", see figure 1 , the equipment whose material arrives last starts first, and the equipment whose material arrives first starts last. The basic requirement of this starting method is: the upstream equipment can only be started when the downstream equipment has been started and running, which is called interlocking condition. . The advantage of this method i...
