JPH0311291A - Gun spray device for vertical refractory material - Google Patents

Abstract

PURPOSE: To obtain an easy-to-handle refractory gunning apparatus having a horizontal nozzle wherein the water supply conduits and material supply conduits are integrated into a mixer-swivel head which controls the swiveling and rotation of the conduit. CONSTITUTION: A vertical gunning apparatus 15 is lowered through an opening 42 down into a vessel 50 using a base 43 and held in place by means of a cantilever beam 41. When refractory material is fed through a supply conduit 21 to the top of a housing 40, the material is fed through the conduct 21 to a nipple 30 and enters into a bearing head 2. Water fed from a conduit 22 is ejected through a water ring 12 into a nipple 33 in the head 2 where it is mixed with the refractory material. The mixture enters into a pipe nipple 3 lined with an abrasion resistant liner 8. Since the liner 8 is fitted to the water ring 12, the nipple 3 is turned by a bearing 26 and the mixture is gunned vertically to the wall lace of the vessel through a lined nozzle 6. According to the structure, an easy maintenance durable gun can be obtained.

EXAMPLE 1 FIG. 1 shows the apparatus of U.S. Pat. No. 3,799,445.

In the case of rebuilding due to attrition in the conduit system, the via nozzle 6, counterbalance 5, and spreader pad 38 must be removed when the device leaves the refractory-lined vessel. When a material supply conduit device 20 is removed, the device is moved into the open area for rebuilding.

During reconstruction, external structures must be completely removed and accommodated. Initially, the device is deactivated via the control box 18. The chain 23 is rotated to approach the chain connecting link 1 (not shown), which is then removed to the free chain 23. Two sets of screws (not shown) on the bearing 26 are loosened and the four bolts 31 holding the water/refractory material mixture rad 32 in place are loosened. The hose nipple 33 extending from the water supply conduit 22 controlled by the water control unit 17 must also be removed. The internal conduit can be removed through the top of the conduit housing 40.

Each piece of internal conduit must be accommodated. Pipe nipples 30.34 are screwed into both ends of the water material mixing head 32. The other end of the pipe nipple 34 is mounted on a swivel bearing to a head 35, and a via'nipple 37 is attached to the head 35.
Attach it to the bottom of 5. This reconstituted conduit is then lowered through the conduit housing 4Q, after which the chain 23 is placed around the sprocket 36 and the connecting links are secured. Motor 16 is properly mounted to apply proper tension to chain 23. Next, the bearing 26
and the hose nipple 33, mixer head 32, material supply conduit device 20, spreader head 38, pipe nozzle 39 and counterbalance 5 are inserted again into their respective positions.

In the present invention, for example, as shown in FIG. 2, a vertical gun blowing device 15 is inserted into a container 50 lined with refractory material from the top of the container or from an opening 42 formed by the operator using a platform 43 near the top of the container. The device 15 is lowered into the instrument 50 and held in place by a cantilever beam 11 attached to the door frame 42 on the outside of the instrument. Refractory material is supplied via material supply conduit 21 to the top of gun blow conduit housing, 40. Water is supplied to a conduit 22 (not shown).

The refractory material is supplied via a material supply conduit 21 to a material supply conduit nipple 30 having a material supply conduit system 20 and a handle, as shown in FIG. This nipple 30 is lined with an abrasion resistant liner 13. This refractory H then enters the mixer swivel bearing head 2. Water enters via the water supply conduit nipple 33 in the head 2 and is ejected via the water ring 12. As shown in FIG. 4, rubber seal 14 and O-ring 19 seal water ring 12 to prevent possible water leakage. The water is mixed with the refractory material in the head 2.

A bearing arrangement 11 is shown in FIG. This bearing device 11
is the inner gauging 4 surrounding the water ring 12.
and a bearing II surrounding the inner casing 4.
It has A and. This bearing IIA is secured in position by a lock nut 10, which is then surrounded by an outer casing 2A. The inner casing 4 is fixed and the two outer casings cooperate with each other, and the rotation of the outer casing 2A is caused by the bearing 11A.
controlled by. The rotation and pivoting of conduit 100 is thus substantially controlled by bearing arrangement 1N without the need for a separate pivot joint. Reversible motor 16
A sprocket 9, driven by and remotely controlled from outside the refractory lined vessel, surrounds the outer casing 2A and also controls the rotation and pivoting of the conduit 100.

As the wet mixture continues to move through the conduit, it enters further into the pipe nipple 3 which is lined with a rot resistant liner 8. This liner 8 fits snugly over the water ring 12 and keeps it stationary. The pipe nipple 3 joining the bottom of the mixer pivot head 2 to the spreader head 38 rotates when driven by the bearing 26. The refractory mixer is then lined with an abrasion-resistant liner 7 and set, for example! It is applied via a nozzle 6 fixed by 124, which applies the wet refractory material perpendicular to the surface of the vessel wall. Further, as shown in FIGS. 2 and 3, a light 51 is provided on the outside of the housing 40.

The vibration drive mechanism of the vertical remote control refractory device is patented in US Patent No. 3.
, 799,445. Generally shown in Figures 2-4 of U.S. Pat. No. 3,799,445, the device is actuated by an electrically conductive motor rotating a crank disc connected to the drive portion of the clutch. There is. In this way, the rotation of the crank disk causes the driving part of the clutch to vibrate.

During the necessary rebuilding, the only parts to be collected are the material supply conduit system 2...the nozzle 13, the water ring 12, the pipe nipple liner 8, and if necessary the liner 7 in the nozzle. . This is because these are the parts that come into contact with the abrasive refractory material. These are accessible without disassembling the entire device. In fact, most reconstructions can be completed from the top of the conduit housing 40 in a minimal amount of time.

Easy repair of the device is also shown in FIG.

- the liner 1 in the material supply conduit unit nipple 30 is removed by removing the material supply conduit unit nipple 30 using the handle 1 (without the need for special tools);
3 is collected, and the two oter rings 12 and liner 8 in the lower pipe nipple 3 can be accessed. The liner 7 within the nozzle 6 can also be easily retracted by loosening the set screw 24 that holds the liner 7 in place.

Next, the liner 7 is removed and stored, and the set screw 24 is tightened.

Water ring 1 in pipe nipple 3 (No. 4 [a)
There is provided an alternating liner insert 25 (FIG. 5) in which the liner 2 and the liner 8 are combined as one unit. In this structure, the O-ring liner insert 25 is integrally formed with an O-ring at a predetermined position to seal out water.

The ortalin grainincer 1 slides into position from the top of the mixer swivel bearing head 2.

A rubber gasket 14 is then placed on top of the watering liner insert 25 to seal out water.

The liner 13 in the material supply conduit nipple 30 is retracted and the material supply conduit nipple 30 is pulled back tightly using the handle 1.

[Uman] 1 This gun blowing device is easy to use. Reconstruction of this equipment consisted of the removal of a one-piece, material supply conduit unit nipple. This gun blower is easy to use with minimal maintenance time.

The anti-explosion liner 7.8.13 also extends the life of the conduit, thus reducing rebuild time.
