Definitions

  • the subject of the present invention is the rotary feed device for solid fuels, particularly suitable for stoves, boilers, fireplaces or cookers, which is defined in claim 1.
  • the originality of the device lies in the fact that it has a fixed cylinder with a horizontal axis, and a rotary charger with radial sectors which is housed inside the cylinder and which, containing solid fuels such as wood, coal , briquettes or the like, turns around the axis of the aforementioned cylinder.
  • the movement of the rotary loader can be automatic or manual.
  • the mechanism can be controlled either by an electrical or electronic control unit which, in turn, receives a signal from sensors which read the temperature of the fumes or water from the boiler, or more simply by means of a programmer timer.
  • combustion chambers of all the aforementioned devices that is to say stoves, boilers, fireplaces or stoves, are equipped with a door for loading fuel, generally wood, but also coal or other type of fuel which necessarily requires continuous, constant manual recharging to maintain the temperature in the combustion chamber.
  • the object of the device according to the invention is to avoid having to continuously load fuel, with obvious advantages both in terms of saving time and fatigue, autonomy, efficiency, cleanliness, pollution, as well as the operation and duration of the generator.
  • the device according to the invention makes it possible to carry out a continuous and constant metering of the fuel before the combustion succeeds in completely consuming the embers, that is to say, it makes it possible to obtain a constantly optimal combustion curve, thereby excluding the phases constituted by the more polluting "tails".
  • the present invention therefore increases the efficiency in the sense that it perfectly maintains the combustion parameters, by constantly supplying the right quantity of charge to the combustion chamber.
  • the device according to the invention which produces an apparatus capable of ensuring a fuel supply for up to 24 hours, completely automatic and free of manual assistance is therefore extremely advantageous and useful.
  • the supply device according to the invention can be produced in two different forms, both of which have the same operating principle:
  • the automatic loading of fuel into the combustion chamber takes place by a controlled rotation "step by step” of the radial sector loader 2, which rotates in the fixed cylinder 3.
  • This sector loader 2 contains and drives the fuel reserve in a rotational movement and, at each step of the rotational movement, it discharges by gravity the contents of a single compartment in the combustion chamber 4, in the sense that the hatch 5 which closes the compartment tilts down by gravity, because it can rotate around an axis 6.
  • the "step-by-step" cycle which is established is as follows: after the first ignition and the subsequent heating of the combustion chamber, a sensor is provided to detect the lowering of the temperature following the exhaustion of combustion.
  • This signal sets in motion an electric motor 7 equipped with a geared motor, to impart a partial rotation to the mobile charger, rotation which is stopped by an end-of-travel device suitably mounted, until the sector has discharged the combustible.
  • the electric motor 7, mounted on the rear part of the device, is controlled by a control panel, not shown, which receives and processes the pulses coming from the temperature probes.
  • two coaxial fixed steel cylinders 8 and 9 are provided, with a horizontal axis, while inside these cylinders, a rotor having compartments 10 rotates.
  • the fixed cylinders 8 and 9 have, in the upper part, a missing surface part or opening to make room for the combustion chamber 11.
  • the compartment rotor 10 consists of a circular crown concentric with the fixed cylinders 8 and 9, with partitions 10 welded perpendicularly and arranged radially with respect to the axis of rotation.
  • the movement of the mechanism is generated by an electric motor 14, equipped with a device capable of reducing the number of revolutions, so as to produce a rotational speed suitable for the intended application.
  • This motor is advantageously mounted on the rear part of the boiler or of the stove 15 and is controlled by a control panel, not shown, which receives and processes the pulses coming from the temperature probes.
