必要であり、生産性のロスが発生していた。(Configuration of the prior art and its problems) As shown in Figure 7, the firing equipment of a pellet factory generally dries, dewaters, and preheats the raw material for firing in a grate 1, fires it in a kiln 2, and transfers the fired product to a cooler 3. The grate 1 has partition walls 7 in a drying chamber 4, a separation chamber 5, and a preheating chamber 6.
It is separated by. As shown in FIG. 8, this partition wall 7 is constructed by integrally fixing the upper end of a hollow partition wall 9 made of a stainless steel plate to the ceiling housing 8 of the grate 1, and stacking refractory bricks 10a on the high-temperature side surface. It is constructed by attaching a refractory castable 10b to the surface, and the structure is not designed to allow the partition wall 7 to be moved, but if it were to be moved, it would be 22
This will require a construction period according to the schedule. By the way, the room allocation for Grate 1 is designed according to basic specifications, but there may be cases where it is necessary to change the firing conditions depending on the raw material situation or production balance, and in that case, the room allocation for Grate 1 is It is necessary to change the partition, and partition wall 7 should be changed to
This is done by moving from the position of the virtual line to the position of the solid line in the figure. However, with the above configuration, a long-term shutdown of the operation is required to move the partition wall 7, resulting in a loss of productivity.

と連なつている。(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 to 6. The overall configuration of the firing equipment is the same as that explained in the conventional example, so the explanation will be omitted.
Identical components are given the same reference numerals.
The ceiling housing 8 has a mounting position for the partition wall 7 and a plurality of positions in front and rear of the mounting position.
A support member 11 for supporting the partition wall is disposed embedded within the fireproof castable 27. A cooling air passage 12 is formed on the high temperature side of the support member 11 to cool the fastening portion. Support member 1
1 includes an upper end flange portion 13a of a hollow partition wall 13;
are fastened and fixed with bolts and nuts. This partition wall 13 is divided into a plurality of parts in the width direction and can be joined with bolts and nuts, so that it can be easily installed by dividing the parts from a nearby manhole and carrying them into the grate 1. 13
A side plate 14 and a bottom plate 15 are attached to the flange portions 13b at both side ends and the flange portion 13c at the lower end, respectively. In addition, a pair of left and right zigzag cooling air passages 16a and 16b are formed over the entire surface of the hollow part of the partition wall 13, as shown in FIG.
Air pipes 18a, 1 are connected to the inlet 17 at one end of each
8b is connected, and elbow-shaped short outflow pipes 20a, 20b are connected to the outflow port 19 at the other end. Further, a cooling air passage 21 is formed on the high temperature side of the upper end of the partition wall 13 to cool the fastening portion. The cooling air passages 12 and 21 for cooling the fastening part
Blower branch pipes 22a and 22b branched from the blower pipes 18a and 18b are connected to. A support bar 23 for preventing shaking is provided on one side of the lower part of the partition wall 13 on the low temperature side, and as shown in FIGS. 5 and 6, a bracket 24 installed on the support bar 23 and the partition wall Fixing member 2 attached to the side of 13
5 are fastened and fixed with bolts and nuts, and one of the bolt holes is made into a long hole to absorb thermal expansion and contraction of the partition wall 13. Both sides of the partition wall 13, side plates 14 and bottom plate 15
A stud 26 is attached to the surface of the support member 11, and a fireproof castable 27 is attached by spraying.
It is connected with.

間は約８日程度で済むのである。 In the above configuration, when it becomes necessary to move the partition wall 7, the main burner is turned down and the grate 1 is cooled to the extent that a person can fit inside the grate 1, and then the refractory castable 27 is removed, and then the support member 11 and the partition wall are removed. Loosen the bolts and nuts fastening the partition walls 13, and remove the partition wall 13 one by one while dividing it. In this way, the support member 11 after the partition wall 13 is removed is buried by attaching and repairing the fireproof castable 27. On the other hand, after moving the removed partition wall 13 to a desired mounting position and exposing the support member 11 at that position by removing the fireproof castable 27, attach the divided pieces of the partition wall 13 to the support member 11 using bolts. They are attached one by one using nuts, and finally the side plates 14 and the bottom plate 15 are attached, thereby assembling the partition wall 13. Next, the blower pipes 18a and 18b are connected to the partition wall 13, the support bar 23 is relocated and combined with the partition wall 13 to prevent it from shaking, and a fireproof castable 27 is sprayed onto the surface of the partition wall 13 to attach it. . After that, the main burner is ignited and the temperature is raised to enable operation. The construction period during this period will be approximately 8 days.

Since it is removably connected and fixed with nuts, and a refractory cable connected to the refractory cable is attached to the surface of this partition wall, the length of the drying, water repellent, and preheating chambers of the firing equipment can be changed as the firing conditions change. If you want to change the firing conditions, you can easily adapt to the desired firing conditions by attaching the partition walls that partition each chamber to support members placed at desired positions. Since it is buried in the fireproof castable, there is no risk of deformation, etc., and when the partition wall is installed, it can be installed reliably.

上大なる効果を発揮する。 Furthermore, when moving the partition wall, the partition wall can be easily moved by removing it from the support member and fastening it to another support member that has been set in advance at the position to be moved, making it easier to move the partition wall than in the past. Since the period is extremely short, it has a great practical effect.
