Description

The The invention relates to a Holzofenbeschickverfahren and a Holzofenbeschickvorrichtung.

at the heating with wood there are several possibilities. A possibility is to use pellets or wood chips stored as bulk material can be. Consequently, it is relatively easy to use a wood stove via an automatic filling device to supply with the pellets or wood chips.

at the use of firewood or firewood proves this, however, not possible because the promotion of logs causes problems. This is canted or jammed and thus can not be funded automatically. For this reason it is known that log stoves, which meter logs or half-meter logs burn, each manually must be charged. This process must, depending on from the burn, several times a day respectively. An automatic operation of such a wood stove is thus not or only very limited possible.

The DE 102 08 318 A1 describes a loading machine for automatically loading a service elevator for stoves and fireplaces. In this case, a drum magazine on several subjects, which can be emptied by lateral pivoting. The kiln drops in an unordered manner from the individual subjects. For the handling of logs, such a device is unsuitable.

From the DE 35 37 841 A1 a feed system for solid fuels is known, which comprises a fuel storage wheel with segment compartments, which are each closed with radial, pivotable partitions and is divided into radially outer and inner storage compartments by means of hinged shelves. Again, the kiln falls in an unordered manner from the individual segment compartments.

Of the Invention is based on the object, a device or a To provide method of the type mentioned, which in a simple Construction and easier, cheaper Applicability of the fully automatic operation of a wood stove with firewood over one long period allow.

According to the invention Task by the feature combinations of the device claim or the method claim solved. The respective subclaims show further advantageous embodiments.

According to the invention is thus provided with respect to the device that a plurality of storage body provided are in which each batch of logs are recorded. These batches correspond to the filling of a wood stove. The individual storage body are housed in a storage magazine, which preferably can be designed as a carousel magazine. According to the invention is still a loading device provided to the content of each one storage body and from the storage body position to the loading area of the furnace (hopper) to convict.

It is according to the invention thus possible Automatically individual batches of firewood from the storage magazine into the wood-burning oven. At a Sufficient number of storage tanks can thus make the wood stove over one be operated continuously over a very long period of time.

Regarding the inventive method It is intended that the firewood initially in an orderly assignment in the at least one storage body is stored, and in a likewise ordered assignment of the storage body in the Feeding device is transferred. Below is the firewood (also in ordered allocation) stored by the loading device in a filling of the furnace. The firewood is according to the invention during the entire process forced out.

The inventive method can run automatically without a supervisor or operator must be present. Therefore, the invention is suitable for automatic loading from wood stoves with firewood.

According to the invention several possibilities, insert the firewood into the storage body. This can be done purely manually or by suitable conveyors, For example, conveyor belts or the like. Since the billets are mechanically produced in the woodcut, arise precise lengths as well as essentially predetermined thicknesses of the individual logs, whereby this, for example, with grippers or the like, can be handled.

According to the invention, the Feeding of the furnace either in a given time interval or burn-dependent done. Here, for example, over a temperature control and / or level indicator of the furnace found if all in the hopper the wood is burnt and recommends a new filling is.

With regard to the device, it is special favorable if the storage body is formed like a box. In this case, it preferably comprises a lifting floor, so that the logs located in it can be lifted upwards and transferred into a pocket-like loading device. As a result, the forced operation of the log is not abandoned, but this remains in the predetermined assignment. Jamming or tilting is thus completely excluded.

The Preferably pocket-type loading device is preferably provided with a bottom, which can be opened or closed as desired can. The floor may, for example, individual fingers or support elements include, which are pivotable or displaceable. The lifting floor of the storage body can also rusty or similar be formed, so that an interaction of the bottom of the charging device with the lifting floor of the storage body is impossible.

According to the invention pocket-like loading device so movable or movable that they in a hopper a furnace is einbringbar. Thus, the positively driven firewood inserted directly from the charging device in the hopper of the furnace become. Below you can the movable support elements or the bottom of the loading device can be opened, leaving the firewood in an ordered assignment in the hopper of the furnace can be.

It It is understood that other technical solutions are possible to that in the storage magazine in the individual storage bodies stockpiled plywood to be transferred to the loading device and by means of this in the hopper of the furnace. In any case, the invention provides that the firewood is forcibly guided is moved and not disordered, for example falls, is poured or slips. Thus, the invention ensures that the entire logs sorted in a batch and trouble-free supplied to the wood stove becomes.

in the Below, the invention is based on an embodiment in connection described with the drawing. Showing:

1 a schematic plan view of an inventive storage magazine,

2 a schematic side view of the filling of a storage body, and

3 - 21 the various process steps for removing the billet from the storage body and for depositing the billets in a hopper of a furnace.

The 1 shows in plan view schematically a furnace 5 with a hopper 8th , The furnace can be, for example, an oven from the company HDG Bavaria GmbH, which is carried out via a lower burn-off and with an upper filling door 9 is provided, which by means of an actuator 10 can be opened or closed automatically.

Out 1 it is apparent that the storage magazine 3 a variety of storage bodies 1 includes, which with the log wood 3 can be filled. By the rotation of the storage magazine 3 this is a respective charging device 4 assign it to a storage body 1 is located in the area of the charging device. The loading device 4 will be explained in detail below.

The 3 to 21 show the individual workflows of the method according to the invention. In 3 a state is shown in which the storage body 1 with the firewood 2 is filled. The storage body 1 includes an internal lifting floor 6 , which by means of an actuator 12 (Piston-cylinder unit, similar to the actuator 10 ) can be raised. In 3 is the loading device 4 above the storage body 1 arranged their ground 8th , which includes lateral, pivotable support elements is open. The loading device 4 includes a bag 11 , in which a plunger 13 is arranged, which by means of an actuating device 14 (Piston-cylinder unit) can be lowered to the firewood 2 in the hopper 8th of the oven 5 depress (see 13 ). An enclosure or cover 17 tightly enclosing the bag 11 and prevents the escape of smoke or gases when filling the stove and a possible burn-back.

The pocket 11 is by means of an actuator 15 (Piston-cylinder unit) can be raised or lowered and along a rail 16 traversable.

In 4 a state is shown in which the actuating device 12 the lifting floor 6 pushed up to the firewood 2 in the pocket 11 to press. The 5 shows a state in which the ground 7 closed is. The actuator 12 can thus the lifting floor 6 go back, as in 8th is shown.

The filled charging device 4 subsequently moves along a rail 16 from the position of the storage body 1 to the position of the hopper 8th of the oven 5 , The filling door 9 of the oven 5 is still closed at this time, it will, as in 11 shown, subsequently opened. The slider 9 or the filling door 9 open to the combustion chamber only when the filling bag 11 including the this surrounding enclosure or cover 17 which the bag 11 surrounds, firmly on the hopper 8th seated. Thus, it is ensured in case of failure that no flame back outside the furnace is possible and the charging device according to the invention is thus safe from fire. By means of the actuator 15 thus becomes the bag 11 when the ground is closed 7 in the hopper 8th lowered. The following will, as in 13 shown the ground 7 open. Now presses the plunger 13 by means of the actuator 14 the firewood 2 in the hopper 8th , After this process is done, the actuator pulls 14 the plunger 13 back, the actuator 15 moves the bag 11 up ( 14 ). Now is the hopper 8th of the oven 5 with the batch of firewood 2 filled. The floor 7 the pocket 11 the charging device 4 is closed, leaving the actuator 10 the filling door 9 of the oven 5 can close again.

The loading device according to the invention leave the oven position only when, for one thing, the firewood was discharged into the oven and on the other hand, the slide 9 (Filling door) the oven has closed again safely. The charging device is thus designed so that fire and flue gases can not escape. If, for example, a power failure occurs during the filling process, it is ensured that no burn-back can occur.

Subsequently, the process repeats in which, as in 18 shown the loading device 4 again over the storage body 1 is moved. For the next batch filling, as in 21 shown the storage magazine 3 one turn further, so that the whole process can be repeated.

Thus, a batch, fully automatic loading of the furnace 5 possible, so that it can be operated automatically over a long period of time. Depending on the size of the storage magazine 3 For example, this period may take many days, so it is sufficient, for example, once a week, the storage magazine 3 to fill with firewood.

The individual actuators preferably hydraulically actuated. This allows very slow movements result, which are less prone to failure and for any persons who are in the area of the storage magazine, harmless are.
