DE432218C - Method and device to prevent the formation of voids in the generator filling by compression - Google Patents

Description

Method and apparatus, the formation of voids in the generator filling to prevent by squeezing. About the formation of voids in the generator filling To prevent this, one already has various means of compressing the filling applied.

In one device, for this purpose, the filling is from below compressed. This compression takes place periodically, shortly before each loading, at different intervals depending on the type and procurement of the substance to be gasified takes place. This is the formation of cavities in the time between loads is not excluded.

In another device, a periodic compression is used avoided by continuously acting in the manner of a drop hammer presses on the generator filling. Here, however, the compressive force is depending different sizes according to the height of the filling, so that with a large filling almost only that Weight of the plunger for pressure generation comes into consideration.

According to the invention, an uninterrupted and even compression is achieved the generator filling achieved in that on the fuel surface permanently a pressure of constant strength is exerted from above.

On the drawing is a generator with a device for exercising a permanent and even pressure on the filling according to the invention in vertical sections shown.

The generator a corresponds to the rest of the usual generators. From the filling shaft b, the fuel c reaches the combustion chamber d, and that gas, which develops in this known manner, flows out of the discharge nozzle e after the point of consumption.

In contrast to known devices of the same type, however, the generator shown is made suitable for exerting a flexible pressure on the fuel and thus for preventing the formation of cavities in the fuel, in that a loaded piston f is provided in the filling shaft b. In the exemplary embodiment, the resilient loading is effected by weights g which load on the piston rod i guided through the manhole cover lt. Instead of the weights, springs can of course also be used to depress the piston, or the piston can be under the action of compressed air either directly or by means of a second piston. If necessary, compressed gas can also act directly on the contents of the hopper as a pressure medium.

When loading, the piston f and the manhole cover h are expediently brought from the position shown in solid lines to the position shown in dash-dotted lines by means of crank k and pulling element l , and after loading, the cover h is placed on the hopper b , and the piston f pushes when released the crank k down the fuel until it comes into the position shown in solid lines. It is easily understandable that cavities are automatically eliminated by filling them as they arise.

The load on the piston varies depending on the type of fuel chosen large.
