An inlet 10 having a horizontally long rectangular connection flange 9 for dropping powder and granules is provided on the uppermost surface of the center portion of the end plate 2, and four hanging fittings 11 are provided radially downward. Is provided. A large number of mounting holes 12 are formed in the flange 9, and a receiver filter 13 having a bag filter is provided.
And a particulate air transport pipe 14 for supplying the particulate to the receiver filter 13. The receiver filter 13 removes the air, separates the air and the granular material, and removes it by backwashing to maintain the filtration efficiency. The structure of the bag filter portion of the receiver filter 13 is well known, and for details, refer to Japanese Patent No. 2634042. A plurality of circular windows 15 are provided at two upper and lower positions on the right side surface of the body 3 for observing the accumulation state of the granular material charged into the silo 1. In the vicinity of the right side surface of the lower circular window 15 (below the trunk portion 3 in the figure), a silo inspection port 16 protruding to the outside from the side surface of the trunk portion 3 is provided.
The silo inspection port 16 has a door that can be opened and closed, and the silo 1
It is for cleaning and inspecting the inside of.

As shown in FIG. 4 to FIG.

Are fixed by an air guide 35, and a retainer 34, which is covered with an envelope-shaped filter cloth 33 in the hole of the cell plate 31, is disposed above the air guide 35. A pulse jet type air is supplied by a diaphragm valve 37 with an electromagnetic valve to perform a backwashing operation. At the time of dust collection, air inside the silo 1 is sucked by a fan 38, and an air pressure is detected by a manometer 39 (differential pressure gauge). The flow of the air 40 is controlled by a sequence controller, and inspection and cleaning are performed by an inspection door 41.

The lower module 7 has a cylindrical outer shell,
A chamber is provided therein. Lower module 7
A discharge port 17 (see FIG. 2) for discharging the granular material supplied by the table feeder 8 to the outside is opened in a peripheral portion of an outer region of the bottom plate 6 inside the server. Are connected to a pipeline 19 (see FIG. 2) via a rotary valve. The lower module 7 is provided with a silo inspection port (manhole) 7a having a door that can be opened and closed. When the lower module 7 is viewed from the back, there are inner flanges and four holes. The skirt base shape provides excellent stability.

When the silo 1 is viewed from above, the flange 20 at the lower end of the body 3 is mounted on an annular mounting surface 21 around the upper surface of the lower module 7 as shown in FIG. It is attached and fixed to a hole (not shown). The level sensor 23 (see FIG. 1) detects the height of powder accumulation, and is provided in the hopper 5.

The above-mentioned end plate 2 has an upper surface gently inclined along the outer peripheral direction, a rounded edge, and a substantially vertical side surface. FIGS. 7A and 7B show a modified form of the end plate 2. In (a), the side surface and the upper surface are substantially perpendicular to each other, the periphery is rounded, and (b) is a substantially arc shape.

Next, the operation of the silo 1 will be described. When a mixed phase flow of the granular material and the air is dropped into the upper module 4 through the inlet 10 of the silo 1 during the transport time from the granular material transport pipe 25, the granular material falls inside the upper module 4 and falls. Is stored. The receiver filter 13 performs air release and dust collection. After the transport time of the multiphase flow is over, next, only air is blown into the inside for about 10 to 20 seconds, and the residual particulates such as the particulate transport pipe 25 are sent out. At that time, the inside of the silo 1 has a positive pressure, and as shown in FIG. 8A, the air flows smoothly along the inner wall of the end plate 2 to rectify the equal pressure, so that the powder particles hardly adhere. On the other hand, in the comparative example shown in FIG.
Due to the corners on the ceiling surface, turbulence is generated, and at the same time, the pressure is biased depending on the location, so that the granules do not flow in a certain direction, and the granules easily adhere. Then, if necessary, the blades of the table feeder 8 rotate to send out the granular material to the discharge port 17, enter the pneumatic transport server 18 via the discharge port 17, and are pneumatically transported from the pipeline 19.

By adopting a cylindrical body 3 and an end plate (end plate 2) for the top plate, powder adhesion inside is minimized, and particularly, the powder remains on the upper inner wall of the silo 1. Eliminating the powder and granules can prevent contamination (contamination) due to propagation (rot) of various bacteria caused by the powder and granules, and the cleaning operation becomes extremely easy.
A device conforming to the concept of the CCP can be realized. Since the body 3 is round, the number of welding points can be reduced and the cost can be reduced. It has a flowing design from the top to the bottom without any reinforcement ribs, etc., which gives the aesthetics of the factory and makes cleaning the outside very easy. By employing the lower module 7, the need for a gantry is eliminated. A pneumatic transport server can be installed in the lower module 7 chamber. Since the air transport server 18 and the table feeder 8 are surrounded by the outer shell of the lower module 7, noise can be prevented, dirt is prevented from adhering, and cleaning is facilitated. Since the upper module 4 and the lower module 7 are made into modules in advance, the transportation and installation work is reduced. The unit construction method for connecting each unit can greatly reduce the number of installation steps on site. A low cost model in which each size is completely standardized can also be used.
