Your variable scopes are wrong. Try this:

function conectarDB($svrName, $user, $pwd,$dbName){
    $this->conexion = mysqli_connect($svrName, $user, $pwd,$dbName); 
    return $this->conexion;
}

function consultaDB($consult){
    $result = $this->conexion->query($consult);
    return $result;     
}
