It relates to something that is suspended and stirred in the furnace core a by one part and can be quickly processed without adhering to the inner wall of the furnace core tube.

充満することになり管内閉塞等の悪現象も生じていた。Conventionally, rotary kiln-type rotary retort furnaces have been used for oxidation and reduction of metal powders such as iron, copper, molybdenum, and tungsten, other heat treatments, drying or roasting of food powders, and heat treatment of fine powders such as fly ash. is used. The rotary retort furnace is constructed by installing an IAI heating device inside the furnace, or by heating the furnace core 'U! ! Various types of rice granules are made to flow through the rotating furnace core (d) by means of a heating means such as feeding a heat medium (7), and the heat treatment is performed by bringing these heating mediums into contact with the object to be treated. However, since the above-mentioned processing temperature requires relatively high crystallization temperature, metal powder in particular softens or melts and becomes more viscous, which not only causes the hot powder to have a low -F temperature but also causes it to become sintered. There was a risk that a layer would be deposited on the U wall. In addition, due to poor fluidity of sieved moisture and highly viscous food powder, particles form a friction zone during heat treatment and grow in a layer on the tube wall, and these growing particles gradually fill the inside of the U. Negative phenomena such as tube blockage also occurred.

った。As mentioned above, in order to completely prevent the heat treatment effect from being damaged due to the attachment of the material to the pipe type, the front and rear protrusions of the rotary furnace should be struck by 15 degrees fv, or by about 1 g. Although methods such as peeling off the dorsal end with a stick or the like have been proposed, simply hitting the outer circumferential surface of the dorsal end will not remove the
This is not a direct blow to the inner surface, and in particular, the blow effect does not reach the blind center. In other words, if one attempts to maintain one heating length, the device itself becomes larger, which is a disadvantage. In addition, peeling methods using sticks or the like only damage the inner wall of the furnace core tube or are unable to completely peel off the bone wall to the center, making it ineffective despite the labor-intensive work. there were.

As with a general rotary kiln, this device t' is equipped with a slope device (not shown) to ensure that the furnace body 1 is aligned with the outlet 11+11 in the same order as in a general rotary kiln. It is held in a loosely rigid manner on the rear side, allowing the material to be treated to flow easily. A guide vane 9 and a supply hopper 10 connected to the guide vane 9 are connected to the front side of the r-core u2 (left side in FIG. 1). A sprocket 11 is disposed on the end of the shaft 9a of the blade 9 in the system, and drive is transmitted by a sprocket 13 of a motor 12 via a chain 4. Then, a part of the tip of the guide blade 9 is located at the furnace core □
It is inserted into w2. In addition, a sprocket 16 is formed on one side of the 7/white and meshes with a sprocket 18 of a motor 17 installed below via a chino 19, thereby driving the furnace core 12 at a reduced speed. . On the other hand, a ring-shaped projection 20a is provided at the center of the rear aperture of the furnace core tube 2.
The supporting member 20 provided with Jt is connected to the furnace core row 2 by an appropriate connecting member.
The support member 20 is removably supported on the peripheral edge of the supporting member 20.
The outer periphery of the proboscis forms an outlet 21 of the proboscis to be treated.

22 will be enshrined. The part 22 is housed in an internal space extending on both sides of the furnace core 2, and pieces 24 are arranged radially from the mantissa at equal intervals from the rf 23 (3 views in this implementation VO).
It is planted and divided as appropriate in the longitudinal direction. Each of the divided single pieces 22 of these beater parts 22 is arranged in parallel on one end surface of the shaft u23 with bottle shafts 25, 25f, and pressure surface holes 26, 2fj are provided facing each other on the 11g end, so that the adjacent bottle shafts 25 , 25, each unit 22a is positioned 1u and assembled integrally.

ることは云うまでもない。A support shaft 21 is provided protruding from the rear end surface of the rearmost unit 22 a, and a disk-shaped thrust member 15 of 0 pieces is fitted into the core skin Qll 27, and the thrust portion tt 15
is in sliding contact with the ring-shaped protrusion 20aK of the support member 2(). Therefore, the beater member 22 is pushed backward by its own weight along the inclined surface of the furnace core tube 2, so that even if the furnace core tube 2 rotates, no displacement occurs in the longitudinal direction. Note that each tip of the wing piece 24 is provided with a dorsal angle 28 (corresponding to the second corner of the cutting tool) in the direction of rotation.
It is in line contact with the circular surface. In this example, the axis officer 23
Although the wing pieces 24 are planted in the blades, there is no substantial change even if the -4 ends of the wing pieces 24 are introduced to each other. Further, the number of blades 24 shown in this example is not limited to three, and it goes without saying that the number of blades 24 may be more than three.

いる。In addition, 29 is a side roller that prevents the furnace core tube from shifting in the horizontal direction due to heat tension and 111 mouth tilt.
A frame is fixed to the outer surface of the inlet side heat retaining part, and a rotatable roller is supported at the tip of the frame, and the circumferential surface of this roller is in contact with one side of the rotating flange 6. Depending on the situation, one to several units may be installed in total.

Ｖｔ　ｔ。Next, the operation of the beater member 22 will be explained. When the furnace core tube 2 rotates in the direction of the arrow shown in the figure, two of the three blades 2, 1 of the beater member 22 (1), two of which are eight blades 24, are exposed to the nozzles of the furnace core and sieve 2. The remaining 241 pieces of 5.A are in pressure contact with each other on the inside of the furnace core tube 2 and the IS space 10-
in a state. Then, as the furnace core tube 2 rotates, the two blades 24, 24 that are in contact with the inner surface of the furnace core tube σ) region also rotate

This increases the surface area of the powder and brings it into uniform contact with the heating medium, promoting heating of the young fruit. In particular, when the 1" Ml-shaped piece 24 falls against the ・U wall, it hits the furnace core W 2, so the impact action causes the entire furnace core d2 to be hit from the inner surface and scratched by the tip of the sliding door.
