DE429116C - Cooking device for liquid fuels - Google Patents

Description

With the previously known cooking devices, in which petroleum, alcohol and Similar, easily evaporating liquids used as fuel are different This is associated with disadvantages that have often resulted in life threatening and even death when the device is handled by inexperienced persons. The one disadvantage of these older devices is the large amount of explosion danger. To prevent them from happening, the fuel tank has been used to prevent it from developing high levels of heat Burner spatially separated. But there is also a lack of these previously known cooking devices, which by pumping in activated by air and thereby a more or less high interior Pressure have to resist, a safety link that automatically pushes you through strong pumping dissipates generated overpressure and makes it harmless.

Another disadvantage, which occurs especially with petroleum stoves, is that that with the cessation of heating parts of the petroleum in the form of tar in the Cooled lines and precipitate in the burner and contaminate and clog them.

With that, there is now the further disadvantage

connected that when the burner is reignited, the petroleum vapors developed as a result of this clogging of the lines cannot get to the burner.

If the lines become dirty or clogged, then one tries as is well known, by pumping in air, the petroleum is still in a liquid state to push for the flame to vaporize it there. The large amounts of air that are mostly pumped in here, but increase the risk of explosion.

Another disadvantage of the older design, which also creates a risk of explosion can have, consists in the fact that the container that holds the highly flammable fuel, is not sufficiently secured against access or damage.

The present invention seeks to remedy the above-noted deficiencies, and in particular remedying the explosion and fire hazards.

One of the characteristics is that when overpressure occurs in the fuel tank, the pressure relief is automatically brought about by the arrangement of a valve. With the separate arrangement \ 'on burner; and fuel tank can be the safety! valve z. B. be arranged in the central axis of the latter. In this way, the apparatus ensures increased safety / and if it is handled by inexperienced persons, an explosion is ruled out.
This safety element is constructed in such a way that it not only serves to automatically relieve pressure, but also to regulate the flame size by hand, so that the flame can be reduced or completely extinguished by 6g. This valve ensures the highest level of security against careless handling of the device in the event of excessive pumping.

Another feature of the invention is that impurities are present and residues that occur, such as B. tar deposits, etc., both those which are deposited from the fuel container, as well as those from the Burners precipitate, are collected separately and independently of each other, so that clogging of the pipelines etc. cannot take place.

This is done according to the present invention in such a way that at the bottom of the fuel container a smaller container is attached, in which the contained in the fuel Impurities can settle. A similar one, serving the same purpose smaller container is at the lower end of the pipeline leading to the burner attached to in the same the developing and dripping from the go burner or to collect tar residues that run off. These smaller containers can be any Have shape.

In the drawing, the subject matter of the invention is, for example, assuming a single one Brenner's illustrated. However, two or more burners can also be fed from one and the same container. Fig. Ι shows the device in diagrammatic

Licher representation and Fig. 2 in vertical section; Fig. 3 shows a vertical section through the safety and control valve. α is the frame of the cooker, which z. B. can be made of cast iron or other building material that gives the stove the required stability. b is the container used to hold the fuel (petroleum, spirit, etc.). This is surrounded by a protective housing c, which can still be closed with a cover d, e is a safety valve which, as mentioned, is designed in such a way that it can also be used to regulate the flame size by hand in addition to its actual mood. If the internal pressure of the fuel tank exceeds the compressive force of the spring p, the valve pin q with the disk ν arranged in the housing w is lifted from its seat in the usual way and the excess internal pressure can escape through the openings c, s and t. When the pressure equilibrium is re-established, the valve pin q is pressed down onto its seat by the tension force of the spring p, and the valve is ready for new play. The manual control or the shutdown of the stove is done by slightly turning the handwheel u in the housing x, whereby the cone ν is more or less released from its seat, while the vapors generating the internal pressure can escape through the opening t, which weakens the Burner flame or a complete extinction of the same result. f is an air pump which, by pumping in air, generates the required pressure in the container b to drive the fuel to the burner, g is the filling opening for the fuel; h is the burner arranged at a certain distance from the fuel container b independently of the same, which burner is of any type; can be. At the bottom of the fuel container b, a smaller container i connects, which is shown in the drawing spherical ', but can also have any other shape. In this space i, any impurities, etc. contained in the fuel are collected. | vi is the burner tube which is used for burning- | ner ii leads. At the bottom of this pipe is an up! '55 catch pipe η connected, which is also shown spherical in the drawing, but can also have any other shape, j are fuel container b and burner h! connected to each other by the pipe 0, which opens on the one hand in the container i and on the other hand in the collecting space η; through this pipeline the 'transfer of the fuel from the vessel b to the burner /; instead of. The mode of operation of the cooker is the usual one. After a certain pressure has been generated in container b by pumping in air, the fuel flows through collecting space i, pipeline 0, collecting space n, through pipe m to burner h, where it is gasified. Sponsorship τ claims: 1. Cooking device for liquid fuels, such as. B. kerosene, alcohol, etc., with a separate burner and fuel container, characterized in that the latter is secured against internal overpressure by a control member (c) which can simultaneously serve for automatic pressure relief and to regulate the flame by hand. 2. Cooking device according to claim 1, characterized by the arrangement of two collecting containers (i, n) in the fuel line, of which one (i) is arranged below the fuel container (b) and the other (n) below the burner (h) that in the collecting space (i) located under the fuel tank (b) the impurities in the fuel are separated due to their own weight and a pre-cleaned liquid flow is passed through the pipe (0) connecting the two tanks (i and w) to the burner . 3. Cooking device according to claim 1 and 2, characterized by a regulating member serving as a pressure regulator and regulator for the flame size, consisting of a valve body (w) which can be screwed by hand and which is adjustable in the housing (χ) by means of a handle (w), furthermore by a spindle (q) under the action of a spring (p) , which closes the opening (S) of the seat (v) with its disk (y) , and finally through the opening O) in the valve body (w) and the opening (t) in the valve housing (χ) in such a way that when the pressure rises, the disk (v) moves upwards and allows the excess gas to escape through the openings (s and t) . 1 sheet of drawings.
