Description

[Detailed Description of the Invention] Conventionally, in the work of spraying refractories for repairing the inside of a furnace or spraying refractories for forming a fireproof wall, a refractory spraying device has been used to perform the spraying operation on the spraying device itself. The necessary operating functions were fixed, and the spray equipment was operated while observing from the fixed cockpit, making it impossible to observe the inside of the reactor sufficiently.
As a result, accurate spraying work could not be carried out, heat protection measures against furnace heat were particularly poor, and furthermore, there was a lack of compatibility with operational work.

The present invention aims to eliminate these drawbacks and provide a method for operating a refractory spraying device that allows easy observation and operation, accurate spraying work, and highly maneuverable spraying work. .

In this invention, as a refractory spraying device A for spraying refractories, a turntable 2 is mounted on a traveling vehicle 1 as shown in FIG. A rotating cylinder 4 is installed, a shooting pipe 5 that expands and contracts is installed inside the cylinder, and a turntable 2 is installed.
A tank 6 containing water and powdered refractory material is placed on top,
The cockpit 7 is fixed on the same tank, and the running vehicle 1 is placed on the tank 6.
, the operation functions of the turntable 2 and the shooting pipe 5 are assembled, a heat-insulating glass 8 is attached to the front, and the shooting pipe 5 is tilted up and down.

A structure in which the functions of turning, extending and contracting, and the function of rotating the turntable 2 to rotate the shooting pipe 5 left and right are converted into an electrical control method, and the connector 9 of the electric circuit for the operation control is attached to the side wall of the traveling vehicle 1. It is said that

Also, as the operation panel B, the cord 1 is connected via the connector 9 mentioned above.
The operation control circuit is extended to a portable operation wall B that can be carried around by the 0, and the operation control circuit is housed in the operation panel B.

FIG. 2 is an example of the operation panel B, in which the operation lever 11 is a switching operation lever that allows the shooting pipe 5 to extend and contract and rotate left and right, the operation lever 12 is a switching operation lever that tilts the shooting pipe 5 up and down, and rotates it left and right. Air, water, off switching knob, 14 is manual, shooting pipe 5 swing 4
5°.

A 60° switching knob, 15 a water volume control knob, 16 a neck band, and 17 a connector.

Operation levers 11 and 12 of operation panel B having such a structure
By appropriately operating the switching knobs 13 and 14 and the control knob 15, the shooting pipe 5 can be tilted vertically, rotated left and right (rotated), and expanded and contracted as well as the turntable 2.
The shooting pipe 5 can be rotated left and right by the rotation of the , and the operator can move away from the vehicle 1 to a place where he can best observe the spraying condition, so the spraying work can be done accurately and quickly. This can help people feel more free from the heat.

Next, the structure of the refractory spraying apparatus A shown in FIG.
A hopper 21 with an inverted hat shape is attached to collect falling refractories, slag, etc., an observation window 22 is opened in the hopper, a fan 23 is attached to the observation window, and a turntable 19 is attached. A control panel 24 is provided on the top, and the portable control panel B connects an electric circuit for controlling the operation of the vertical spray pipe 20 with a cord 25 via a connector (not shown) provided on the control panel 24. It has been extended and accommodated.

In this refractory spraying device A, the operator gets on the operating table 24,
The spraying work is performed by operating the operation wall B while observing the vertical spray pipe 20, the furnace wall, and the state of furnace wall repair through the observation window 22.

As described above, according to the present invention, the spraying operation can be carried out using the refractory spraying device A and the separate portable operation panel B, in a position and posture where it is easy to observe the spraying state without looking at it. Therefore, accurate spraying operations and repairs can be performed, and heat insulation measures (such as the use of heat shield plates) can be taken appropriately, making work easier and more maneuverable.
