Description
Technical field
The present invention relates to electricity fields, are more particularly to a kind of grouting station electric control system and station electrical control side of being in the milk
Method.
Background technique
Grouting is the major measure in mine preventing and extinguishing fire technology, and the preparation of slurries is that grouting process is by loess and water by one
Certain density slurries are sufficiently stirred by blender after certainty ratio mixing, inject working face, goaf etc. by the road.With mine
Quickening is taken in well production, and grouting quantity increases, higher to the quality requirement of slurries, therefore it is required that the slip house on ground will have efficiently
Electrical equipment and electrical system, and be in the milk station blender cannot back and forth stir and need to artificially manually control, pulping efficiency is low, system
That starches is of low quality.Blender is without the protection that slides down, and electric switch is without earth leakage protective etc., once blender slides down, machine is still being transported
The change of team causes the damage of machine, route, seriously affects grouting, therefore is badly in need of redesign grouting station electric control system and to stir
It is full-automatic that machine can back and forth stir realization.
The electric control system of blender can only control the rotating forward of blender, reversion, stop three kinds of states at present.For stirring
The positive and negative rotation for mixing machine needs manual control, when blender, which is run to, closes on stirring pool one end, it is necessary to " be stopped by manual control pressing
Only " button, for machine to be mixed by pressing " reversion " button by manual control again after motion state to stationary state, starting blender is anti-
To movement, until the stirring pool other end, in cycles, blender positive and negative rotation how many times just need manually to press how many times button, people
Work heavy workload, and blender cannot complete stirring work in the case where no manually participation, and working efficiency is low.Daily
In pulping process, the case where grouter slides down frequent occurrence, treatment process is dangerous and difficult, time-consuming and laborious, delay system
Starch the time.It is very big on the normal operation influence of down-hole fireproof grouting system, biggish security risk is caused to mine downhole production.
