SU34489A1 - Cardox-type cartridge for destruction of hard coal, anthracite and other natural minerals - Google Patents

Description

In the proposed cartridge, Cardox, for the destruction of coal, anthracite and other minerals, for the purpose of heating the coal carbon, electrodes are used for the formation of a volt arc. According to the invention, instead of electrodes, a conductor heated by electric current is applied to a high-resistance alloy entwined with an insulated rod.

In FIG. 1 shows a section of the cartridge in the form of a heater acting on the volt arc principle; FIG. 2 the same, with a heater in the form of an electric spiral.

The main idea of the “Cardox” type cartridge is that the steel bomb / (Figs. 1 and 2) is filled with liquid carbon dioxide, inside of which a heater is placed, from a substance that, when burned, emits a large amount (heat that converts liquid carbon dioxide to gas). extremely high pressure.

The resulting gas, cutting the washer 4 into the ring 3 of solid steel, exits through the hole in the tip 2 into the hole, destroying the coal surrounding the cartridge with its impulse.

If the gas from the cartridge is not removed

outward, and is used to power the hydraulic presses, the tip 2, at the suggestion of the author, is replaced by an exhaust cartridge 2 / (Fig. 2).

The subject matter of the present invention is the replacement of an explosive preheating mixture of Cardox ignited with electricity - by direct electrical heating, carried out either by means of a volt arc (Fig. 1), or by means of a spiral or high resistance alloy (Fig. 2).

In a cartridge of the type "Cardoc", the internal cavity of the hermetically sealed body 7 is filled with liquid Carbon Dioxide, water or the like, which is capable of turning into gas at high temperatures. - On the one hand, the casing / is corked as follows (when working - „Cardox in a hole”. The end nut 2 (FIG. 1) presses, by means of a steel ring 3, a washer from soft steel 4 through a fiber washer 5 to the steps of the body of the cartridge. The closing of the end nut 2 ensures the tightness of the connection. At the other end of the chuck, there is a nipple 7 fixed in the housing T by means of a nut 8. The nipple 7 is electrically insulated from the housing 7, bushings and washers 9, 10, 11.12. On the other, outward-facing end of the nipple 7, a nut 13, 14 is screwed in, in which a valve seat / 5 is installed, sealed with a talc seal 16.

According to the invention, the heating of the pa .tron is intended to produce a volt arc (Fig. 1).

A nipple 29 is screwed onto the nipple 7 through an insulating sleeve 28 supporting the tube 38 of an oxide-containing metal. The tube 38, with its other end, rests on the washer 43 of insulating material, providing one with holes through which, when the cartridge is discharged, gas flows freely.

Shayb b and 2 hold inside the tube 38 a carbon electrode 39, provided with a tip 45 of a metal that is not oxidised but has good conductivity. The 5P electrode is pressed onto the washer with a spring 41 by a tip // 5. Lastly, leaning on the washer 40 fastened to the tube 38, presses on the washer 42 of the electrode 39, Thus the electrode 39 is electrically connected to the body of the cartridge 7 through the washer.

The other electrode 37, installed along the axis of the tube 38, is insulated by a washer 35, fixed to the body of the tube 38 by a ring 44.

Through a tube 5 (9 of soft iron) with an electrode 57, the said electrode is pressed by a spring 55 (through an insulated washer 57) to an electrode 39 connected to the housing 7.

The dinner 36 is put on the i30 stud, reinforced in the sleeve 29. The stud 30 also serves as a stop limiting the movement back to the nipple 7 of the carbon electrode 37.

The current to the electrode 37 is supplied from the nipple 7 through the solenoid 52 n sleeve 34 (through which the electrode 57 slides freely).

The device works as follows (brazom. Spring- / 7 presses to the washer and electrically connects to the housing / electrode 39. Another electrode 3 is pressed by spring 36 to electrode 39 of the case. When current is switched on, the latter is mounted in the following way: from nipple. 7 to sleeve 29, from there on the solar 52, through the sleeve 5- /, on the electrode 57.

As soon as the current is turned on, the solenoid pulls in the core 55, which, compressing the spring 36, reaches the stop 30.;

Since the core 55 is bonded to the coal1 (1 electrode 57, the latter moves to the side of the nipple 7, open the electrodes and, therefore, ignite the volt arc. When, due to the heating, the gas pressure will increase to the extent that the washer / ejected, the auto current supply will stop and the arc will go out. The outgoing and expanding gases absorb a large amount of heat, cooling the electrodes, which, by the time of release, the cartridge will be relatively cold.

If the arc in the process of heating goes out, then it automatically automatically lights up immediately. As the electrodes burn, which will be observed only after the cartridge has been operated many times, the core 55 moves out of the electrode 57.

According to another variant of electrical heating (Fig. 2), a pin 22 is screwed on the nipple 7 of a Pauuron Cardox, c. in which the heating coil 24 is electrically connected. The coil is made of a non-oxidizing alloy with high resistance to electrical current. The closure of the turns of the helix 24 wrapping the rod 22 is prevented by the sleeve 23 I21 of the insulating material. The other end of the helix 24 is connected to the sleeve, which is electrically connected with the legs 25 to the washer 4, closing the cartridge. The end of the rod 22, facing the washer 4, is positioned along the axis of the cartridge with an insulating washer 26 provided with openings through which the tabs 25 and gases flow out, when the cartridge is discharged. The washer 26 is fastened to the rod 22 with a nut. At the time of discharge of the cartridge, i.e. when the washer 4 is cut, the current is automatically switched off.

The subject matter of the invention.
