In the opening operation of the inner lid, the arm is rotated via the drive mechanism to move the inner lid inward of the conical body. Further, in the closing operation of the inner lid, the arm is rotated in the opposite direction via the drive mechanism to bring the inner lid into close contact with the opening of the conical trunk. Therefore, even if the internal pressure of the can increases, the pressure resistant structure is achieved by the inner lid and the minimum diameter portion of the conical body.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the can body 20 is installed and fixed to a floor E or the like by a support body 24 by connecting conical body portions 22 and 23 to the upper and lower sides of an upright cylindrical straight body portion 21. The smaller diameter sides of the upper and lower conical body portions 22 and 23 are defined as openings, and ducts 24 and 25 are connected to these openings, respectively. Duct 25
Hangs below the floor. The fixing flange portion 25 is provided on one of the openings, for example, on the small diameter side of the conical body portion 23, and the pipes 26 and 27 are connected orthogonally to the respective small diameter sides. The fixed flange portion 25 has a diameter such that the inner lid 28 can be taken out for maintenance and replacement of the inner lid 28.

In the openings 49 of the conical body portions 22 and 23,
For example, as shown in FIG. 2, a flat disk-shaped inner lid 28 is inscribed on the inner circumferential surface side, and the outer circumferential surface of this inner lid 28 is inclined so as to match the inner circumferential surface of the opening of the conical body portion 23. A seal packing groove 30 is provided on the inclined surface 29. Therefore, the inner lid 28 can be opened only toward the inside of the can body 20, and when the pressurized fluid is introduced into the can body 20, the inner lid 28 moves outward due to the internal pressure of the can. The structure is pressed and self-sealing with internal pressure, and does not require a special locking mechanism.

In order to open and close the inner lid 28,
A seat plate 31 is fixed to the outer peripheral surface of the conical body portion 23, a bracket 32 is fixed to the seat plate 31, and one end of an arm 34 is rotatably supported by the bracket 32 via a pin 33. The arm 34 is made of a flat plate material, and the other end of the arm 34 penetrates through a slit 35 formed in the duct 25 and extends inward, and the bracket 3 is provided at a substantially central portion outside the inner lid 28.
6 is rotatably supported by a pin 37.

Further, a piston rod 39 is connected to one end of the arm 34 through a pin 38, and a cylinder 40 for hydraulic pressure or the like in which the piston rod 39 is inserted so as to be able to move forward and backward is attached to a bracket 41 fixed to a seat plate 31. The drive mechanism of the lid body 28 rotatably and pivotally connected by the pin 42 is housed within the vertical range K of the outer peripheral surface of the cylindrical body portion 21 and arranged compactly. Therefore, when the piston rod 39 is extended by the operation of the cylinder 40, the arm 34 rotates and slides on the slit 35 to move the inner lid 28 inward of the conical body portion 23 to open the opening 49 ( If the piston rod 39 contracts, on the contrary, the opening 49 is closed (see FIG. 2).

Thus, since the arm 34 can be displaced through the slit 35 when the inner lid 28 is opened and closed,
The opening area of the slit 35 can be minimized to be substantially the same as the cross-sectional area of the arm 34, and it is easy to shut off the object to be treated and the outside air or the gas (when there is no pressure) in the can 1 from the outside air. is there. Therefore, it becomes possible to prevent heat dissipation from the object to be processed, contamination by the outside air, and conversely, release of the gas in the can body 1 into the installation chamber.

Next, the arm 34 is moved to the pin 3 via the drive mechanism.
When the inner lid 28 is moved into the conical body portion 23 by opening the opening 49 by rotating the inner lid 28 in the clockwise direction about 3, the object to be treated is a duct depending on the inclination angle of the inner lid 28. In order to prevent the bridge phenomenon from occurring when moving to 25, the inclined portion 43 which is substantially parallel to the outer surface of the lid 28 is formed at the other end of the arm 34 on the inner lid 28 side. At the same time, a protrusion 45 is provided at the end of the inclined portion 43, and a plunger 45 is provided on the side opposite to the protrusion 44 and the pin 37. The plunger 45 is biased by an elastic body 46 such as a spring so as to come into contact with the outer surface of the lid body 28. In addition, without the plunger 45, the lid 2
Only the elastic body 46 such as a spring capable of abutting the outer side surface of 8 may be provided on the arm 34 so as to be compressible by the lid body 28.

Further, a stopper 47 made of a rod is installed in the conical body portion 23 at a position where the inner lid 28 is substantially parallel to the axis C (see FIG. 3). This stopper 47 is not arranged at right angles to the axis C, but is inclined so that the object to be processed does not stagnate and the conical body portion 23 is formed along the rod.
It is better to be able to move to the inner peripheral surface side.

Therefore, when the inner lid 28 is opened, as shown in FIG. 3, when the arm 34 moves inward of the conical body portion 23, a portion of the inner surface of the inner lid 28 on the stopper 47 side.
The movement is stopped by hitting the inner lid 28, the inner lid 28 rotates clockwise around the pin 37, and the outer surface side of the inner lid 28 faces the arm 3.
4, the inner lid 28 is kept substantially parallel to the axis C, and the plunger 45 is moved to the elastic body 4
Compress 6.

Therefore, the lid body 28 is kept perpendicular to the opening 49, so that it is possible to prevent the object to be processed from receiving the resistance of the inner lid 28 and causing the bridge phenomenon as much as possible. On the other hand, when the inner lid 28 is closed, when the arm 34 moves to the outside of the conical body portion 23, the elastic body 46 pushes the outer surface of the inner lid 28 to maintain the inner lid 28 in a substantially horizontal state and open it. Face the part 49.

Therefore, an object to be treated is placed in the duct 20 in the can body 20.
4, the inner lid 28 arranged at the opening of the conical body portion 22 is opened, and the inner lid 28 arranged at the opening portion 49 of the conical body portion 23 is closed. After the processed material is put into the can 20, the inner lid 28 on the side of the conical body 22 is closed. Then, pressurized fluid or gas is supplied into the can body 20 through the pipe 26, and drains and the like are extracted from the pipe 27.

In order to facilitate drainage of liquid such as drain, the inner surface of the inner lid 28 is inclined toward the pipe 27 or a groove is formed, and a screen 48 is provided on the upper surface of the inner lid 28. Is good.

Thus, it is not necessary to tilt the can body 20 in order to pay out the object to be processed, and therefore the can body 20 can be fixedly installed as shown in FIG.
In addition, the pipes 26 and 27 to the can body 20 may naturally be fixed.

[0021]

As described above, according to the present invention, the object to be processed can be taken in and out only by opening and closing the inner lid, and the operations and operations associated with the processing of the object to be processed are much easier than the conventional method. . Further, it is structurally simple and can be connected to the front and rear production lines without disconnection. Therefore, it becomes easy to deal with the complete automation of the line. Further, the installation space may be the space of the can itself, which is particularly advantageous when a large number of installations are carried out in the factory.
