Embodiment Construction

[0026] A driving control method for a belt conveyor provided by the present invention will be further described in detail and completely below in conjunction with an embodiment. The embodiments described below are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0027] A driving control method for a belt conveyor, which defines a standard state range: the belt conveyor starts within a standard start time t, and the power required for the normal operation of the conveyor is P0, then P 标2 标1 , t 0 1 , where t 0 , t 1 is a fixed value, respectively the lower limit and upper limit of t; P 标2 标1 , P 标1 ,P 标2 is a fixed value, respectively the upper limit and lower limit of P0;

[0028] The belt conveyor is connected to three motors, which jointly drive the conveyor, and the three motors are connected to the PLC. Further, each of the three motors is equipped with a power detection device, and the power detecti...

Abstract

The invention provides a driving control method of a belt conveyor. The belt conveyor is started in the standard starting time t, the power needed for normal running is P0, P0 is larger than P standard 2 and smaller than P standard 1, and three motors connected with the belt conveyor are connected with a PLC. The control method includes the steps that a, Pn1, Pn2 and Pn3 are input into the PLC; Pn1, Pn2 and Pn3 are the active power of the nth starting of the three motors; b, P which is equal to Pn1+Pn2+Pn2 is calculated; c, if P is larger than P standard 1, t' is larger than t0, and if P is smaller than P standard 2, t' is smaller than t1; and d, the three motors are started the (n+1)th time, and the three motors can be started within the time t'. By means of the driving control method ofthe belt conveyor, the PLC calls the real-time power of the last time of running of the conveyor, the real-time power serves as the input of a real-time power-starting time deduction relation in the conveyor, the optimized starting time is deduced, and energy losses in the starting process are reduced.

Description

technical field [0001] The invention relates to the technical field of frequency conversion driving of belt conveyors, in particular to a driving control method of belt conveyors. Background technique [0002] When the conveyor is running, the start time of the conveyor in a certain process state is usually set to a fixed value, that is, the start time of the conveyor in this process state is fixed, and the time from the stop of the conveyor belt to the set transmission rate is a fixed value. However, due to the different climatic environments in different seasons, the power loss will be different, resulting in different start-up times under different conditions. The start-up time under the standard state (non-bad state) can be taken as the standard start-up time range. In the worse working condition, the start-up time of the conveyor is greater than the value within the standard start-up time range, that is, the start-up acceleration of the conveyor in the worse working co...
