Abstract

The invention discloses an electric control system of a grouting station and an electric control method of the grouting station. The electric control system comprises a motor, a motor integrated protector, an alternating-current contactor, an alternating-current contactor, a leakage protector, a breaker, a first travel switch, a second travel switch, a first time relay, a second time relay, an automatic reciprocating start and reset button, an automatic reciprocating stop button, a forward rotation inching operation button, a backward rotation inching operation button and an intermediate relay; the intermediate relay comprises a coil, a normally open contact and a normally open contact; the first travel switch comprises a normally closed contact and a normally open contact; the second travel switch comprises a normally closed contact and a normally open contact; the alternating-current contactor comprises a normally closed contact, a normally open contact and a coil; the first time relay comprises a coil and a normally open contact; and the second time relay comprises a coil and a normally open contact. The electric control system disclosed by the invention has the advantages of realizing automatic reversion and continuous reciprocating and circulating work of a grouting machine and preventing off-track of the grouting machine.

Description

technical field [0001] The invention relates to the field of electricity, and more specifically relates to an electrical control system of a grouting station and an electrical control method of the grouting station. Background technique [0002] Grouting is the main measure in mine fire prevention technology. The preparation of grout is that the grouting process is to mix loess and water in a certain proportion, then fully stir it into a certain concentration of grout by a mixer, and inject it into the working face and goaf through the pipeline. With the acceleration of mine production succession, the amount of grouting is increasing, and the quality of the grout is required to be higher. Therefore, the pulping workshop on the ground is required to have efficient electrical equipment and electrical systems, and the mixer in the grouting station cannot reciprocate and needs manual control. The pulping efficiency is low, and the quality of pulping is not high. The mixer has n...
