Problems solved by technology

[0002] The belt conveyor is the main transportation equipment for coal mine production. During the coal mine transportation process, due to the excessive belt speed of the belt conveyor, the impact on the lump coal in each transfer link is too large, resulting in a relatively high crushing rate of the lump coal during the transfer process. High, which virtually increases the production cost of coal mines and adversely affects the lump coal shipment business

Abstract

The invention discloses a belt conveyor flow variable-frequency drive speed-adjustable system. The system comprises a belt conveyor, a brake wheel and a coupler, wherein the brake wheel and the coupler are arranged on the belt conveyor; an elastic element is arranged between the brake wheel and the coupler; the brake wheel is fixedly connected with the coupler through a flange; the belt conveyor is provided with a variable-frequency driver, a PLC, a belt speed sensor and an array type belt weigher, the belt speed sensor and the array type belt weigher are both in communication connection withthe input end of the PLC; and the output end of the PLC is in communication connection with the input end of the variable-frequency driver. With the belt conveyor flow variable-frequency drive speed-adjustable system of the invention adopted, the crushing rate of lump coal in a transferring process can be decreased, and the production cost of the lump coal can be saved. The system is easy to operate and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of coal transfer equipment, in particular to a belt conveyor process variable frequency drive adjustable speed system. Background technique [0002] The belt conveyor is the main transportation equipment for coal mine production. During the coal mine transportation process, due to the excessive belt speed of the belt conveyor, the impact on the lump coal in each transfer link is too large, resulting in a relatively high crushing rate of the lump coal during the transfer process. High, virtually increased the production cost of coal mines, and adversely affected the lump coal shipment business. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a belt conveyor process variable frequency drive adjustable speed system, which can reduce the breakage rate of lump coal in the transfer process and save lump coal production. Low cost, simple operation and ...
