SU5840A1 - The shutter between the boot and furnace spaces in the factory furnaces - Google Patents

Description

The present invention relates to a closure for a loading opening in factory furnaces, for example, those which are loaded not from above, but from the side, through vertically located furnace doors. When using such furnaces, the workers who serve them often suffer from the dusty gases that are harmful to health and that are released through the doors and that are harmful to health and that are contained in the smoke. This is particularly the case if, for operational reasons, for example, for the further use of gases, a significant excess pressure must be maintained in the furnace. In the latter case, it is not possible, despite the careful sealing of the doors on all four sides, to prevent the gas escaping under high pressure from escaping through the cracks, which are difficult to remove in the places of contact between the doors and the furnace wall.

The present invention aims to neutralize the gas escaping through the slots and divert it in such a way that it cannot penetrate into the surrounding furnace of the workroom.

To do this, a metal sheet, firmly bonded to it, and a gap formed between this front and the door and the door, is attached to the suction unit before the furnace tube is installed at a close distance from it. Gases escaping when there is an excess pressure in the furnace through the aforementioned leaks in their own combustion door experience a significant decrease in pressure and. due to the reduced pressure created in the gap by the suction device, it is sucked through this gap and outwardly. To enhance the desired effect, several knotted gaps formed by the metadata sheets can be arranged one after the other, so that gases that accidentally come out of the first gap experience further pressure reduction in the next gaps and finally remove the exhaust gas from the device.

There is a significant difference in the purpose and mode of action of the fixture described here compared to lime in zinc and other factory furnaces. Namely, while the devices of the furnace just mentioned, all gases are sucked out of the furnace, mixed with incoming air through the working opening, and unused air is exhausted through the pipe to the outside, when using the proposed device, gases, most likely due to their excessive pressure, continue to remain free of air and can be, if necessary, used for combustion or for the extraction of mechanical energy; on the contrary, only very insignificant quantities of gas escaping through the slots of the furnace door are diverted and neutralized.

The accompanying drawing shows two forms of carrying out the invention in vertical sections.

FIG. Figure 1 shows a double flue valve to a water jacket. The inner door is equipped with a metal sheet mounted on the outside and is shown in the closed position, while the folding door is open for loading fuel. FIG. Figure 2 shows the same form of the implementation of an open door with a side door and a closed outer door at the time of 15 loading into the night. FIG. 3 depicts the same eternal shutter with two metal sheets placed around it.

Inner space is closed from the boot space, b, possibly closing the door c on all four sides. Such a thorough closure is desirable, in the nerves, to enhance the suction effect, and secondly, to reduce the loss of gas to a minimum amount. In front of this door

a d-screen consisting of a metal sheet, a tightly connected with this door and a bottom opening, which is open at the top and bottom, is reinforced. In its upper part, this period passes into exhaust duct e, in which the entire door moves and from which gases are sucked off through pipe f. A sheet placed from the outside of the foregoing considerations is also possible to be very thin from the bottom and adjacent to the walls of the nechi. while the top remains a free opening for suctioning gases.

The shape of the foil but fig. 3 and the idea is similar to the form of the manifestation of FIG. 1, with the only difference being that, instead of one, there are two gaps instead of one furnace. The gases, if they left the space, directly connected to the door, are trapped in the second space, which also leads to the exhaust shaft. The possibility to build on further gaps does not encounter any difficulties.

The proposed invention can be applied to all kinds of factory works, in which the landowner can avoid coming out of the gate and operating gases, such as mine and mining, and other types of ignorance.

Subject on t e n t a.

A shutter between the loading and furnace spaces in the factory furnaces, characterized by the use of c attached to the door c, from the side of the charging funnel b, one or several sheets d at some distance from the door and one from the other, which sheets d, stretch slightly to the walls of the loading funnel b from the sides and, when the door is closed, from below, they form a cavity behind the door, communicating above with the exhaust channel e - f, in order to force the gases to stretch through the densities in the places where the doors with the walls are in contact with each other. Reduce} to one, so not a nonad in the room surrounding her oven.
