Abstract
A blasting device includes a raised portion or collar with the purpose of preventing ejection of the device from a holding fixture. An angled discharge nozzle 17 allows discharge from the device to aerodynamically flow over the collar.
Description
Title of invention: Safety Collar
Description:
Safety collar: Device for and method of safely retaining a blasting device in storage or production line vessels This present invention relates to a modification of a blasting device to provide an ultimate safety factor to prevent said device from ejecting from a socket and holding device which enable the blasting device to be applied to clearing of accretions and coatings in kilns, silos and other production or storage vessels.
In the production lines of cement plants, lime plants, nickel plants, power plants, chemical waste plants, steel plants, aluminium plants, oil refineries and the food processing industry, there are vessels such as preheaters, cyclones, feed pipes, inlet chambers, riser ducts, rotary kilns, coolers, silos, bunkers and hoppers that are subject to coatings or accretions that form on the inside walls.
This leads to problems with the operation and efficiency loss in production.
These include insulation problems as the build-up acts to prevent heat transfer to the transfer medium. The build-ups also disturb air injections into the vessels by blocking air inlet nozzles and disturbing the flow of material thus reducing the production.
According to one aspect of the present invention, there is provided a vessel having a wall defining a kiln chamber, a blasting device with a discharge nozzle, a holding device that connects and secures the blasting device leading through the wall of the chamber, whereby, in operation, a gas discharge is conducted from the blasting device that is introduced through the nozzle and into the accretions of material formed on the inner walls of the chamber.
According to another aspect of the present invention, when the blasting device is used to clear such accretions and blockages in the aforementioned production lines, there is an inherent danger that if the material build-up is hard, the device will eject even though a holding device is clamped onto the blasting device.
According to further aspect of the present invention, to overcome this serious and dangerous problem, the present invention proposes a collar' or shoulder' be forged into the main body of the blasting device at the discharge end of said device so that this raised section' will be unable to pass through the holding device which is secured into the socket and thus be unable to eject from the vessel.
The forging of such a raised collar would require tooling to be made in the form of a dye that would allow the upsetting of one of the ends of the device to the required state.
According to another aspect of the present invention, the invention also allows for a redesign of the discharge nozzle that angles away from the nozzle at an angle to aerodynamically allow the discharge to flow across the raised collar.
The Sockets are preferably connected to the vessel walls by either welding directly after holes are made in the vessel walls at points where accretion is known to accumulate or by bolting to vessel walls if made from concrete.
Plugs can be inserted into the Sockets when not in use. The Plug may be made of a heat resistant steel or other suitable material. The blasting device advantageously comprises a high strength reusable seem less ste& tube an activating head and discharge head, a chemical heater, a sealing washer and a shear disc. The activating head and discharge head are screwed into the tube to form a gas tight seal and a charge of liquid carbon dioxide is injected into the tube.
On activation of the device, the chemical heater causes a rapid increase in pressure of the carbon dioxide until the shear disc is ruptured and the mass of liquid / gas is discharged through the nozzle at the end of the device to break the accretion / coating.
In order that the invention may be more clearly understood, one embodiment thereof will now be described, by way of example, with reference to the accompanying drawings in which:-Figure 1 depicts a cross sectional view through part of a wall of a vessel in a non operational state.
Figure 2 depicts the same cross sectional view of the vessel wall but with the blasting device inserted through the Socket into the build-up, clamped into the holding device which is secured into the Socket.
Figure 3 depicts the same cross sectional view of the vessel wall but after the blasting device has been activated with said blasting device having attempted to eject.
Figure 4 depicts the general assembly of the blasting device Referring to Figure 1 and la, the vessel can comprise of either a hot furnace chamber 1 or a cold storage chamber 2 within which materials are processed or stored.
in the case of the hot furnace chamber the steel wall 3 of the vessel is lined by refractory 4 to retain the desired temperature.
It is on the inner walls that the build-ups of materials S occur.
The build-up is accessed by Sockets 6 which are welded onto the vessel wall after a hole is made through the steel wall and / or refractory lining.
Plugs 7 are inserted into the Socket when in non operational mode.
When build-up occurs, the Plug is removed and a small hole to accommodate the discharge end of the blasting device 8 is made in the build-up.
The blasting device is inserted through the holding device 9 which in turn is located into the Socket and turned through 90 degrees to secure.
The blasting device is then pushed into the build-up and then the clamping bolt of the holding device is fastened thus clamping down on the blasting device.
The blasting device is itself well known and sold under the registered trade mark CARDOX.
The blasting device known as a Cardox Tube comprises a special high strength alloy steel Tube 8 which is sealed at both ends by an Activating Head 11 and a Discharge Head 12 which are screwed into the ends of the Tube. At the Activating Head end of the Tube is inserted a chemical energiser/heater 13 and at the discharge end of the Tube is inserted a steel shear disc 14.
The Tube is then charged with a specific amount of liquid carbon dioxide iS.
in use, on activation, the liquid carbon dioxide 16 is energised and instantaneously increases in pressure until the steel disc 14 is ruptured and the carbon dioxide IS is discharged as a powerful heaving force into the build-up.
in some instances, if the build-up is hard or the clamping bolt 10 has not been secured properly, the blasting device will eject from the holder and Socket.
The raised coflar or shoulder 16 wifl prevent the Wasting device from ejecting from the Holder and Socket and the angled section 17 of the Discharge Head will allow the discharge to flow across and over the raised collar and not directly against the collar.
it will be appreciated that the above embodiment has been described by way of example only and many variations would be possible without departing from the scope of the invention.
