26 is a pressure switch, which detects the pressure in the filter 11,
When the pressure reaches a predetermined value, the drive motor 8 of the blower 9
After stopping the operation of, the motor 24 with a reduction gear is started and rotated in reverse.

Therefore, by adjusting the set pressure of the pressure switch 26, it is possible to control the amount of waste accumulated in the filter 11.

The upper end plate 3 may be an upper lid having a size that closes only the filter 11 and may be fixed to the apparatus frame 1 via another member.

According to the first embodiment described above, first, the motor 24 with a reduction gear is rotated in the forward direction to rotate the movable ring 17 in the closing direction and thereby the sleeve.
When 15 is fully closed, this motor 24 is stopped. Subsequently, when the drive motor 8 is started and the operation of the blower 9 is started, the waste that has passed through the waste transfer pipe and is sucked into the blower 9 from the suction port 10 flows into the filter 11 from the waste inlet 2. ,
It is collected and separated by the filter 11 and deposited on the closed sleeve 15 of the throttle mechanism 14. On the other hand, the air from which the dust has been separated and cleaned is discharged into the atmosphere.

Then, when the amount of waste accumulated in the filter 11 reaches a predetermined amount and the pressure in the filter 11 reaches a predetermined value,
After the operation of the blower 9 is stopped by the pressure switch 26, the motor 24 with a reduction gear is subsequently started in the reverse direction, the movable ring 17 is rotated in the opening direction to open the sleeve 15, and the solid line in FIG. As shown in the figure, the dust accumulated in the filter 11 is dropped all at once due to the pressure in the filter 11, and is thrown into the transport vehicle arranged immediately below the waste discharge port 5. As described above, according to the first embodiment of the present invention, the aperture diameter of the diaphragm mechanism 14 can be made the same as that of the filter 11, and the dust having a small specific gravity can be easily discharged from the aperture of the large diameter. it can.

Then, after a certain amount of time has passed after the waste material has fallen, the motor with a reduction gear 24 is started in the forward direction, the movable ring 17 rotates in the closing direction, and the sleeve 15 is in a fully closed state.
24 stops, and then the drive motor 8 starts and the blower 9
Operation is restarted.

In this way, in response to intermittent operation of the blower 9,
The diaphragm opening / closing mechanism 14 automatically opens and closes, and the waste is smoothly collected intermittently.

When the throttle opening / closing mechanism 14 is opened, the blower 9 is stopped, and the internal pressure causes dust to drop abruptly, which causes a suction action and causes air around the filter 11 to flow into the filter 11. The backflow action separates the wastes adhering to the inner surface of the filter 11 to automatically generate a backwashing effect, and intermittently prevent the filter 11 from being clogged.

5 and 6 show a first embodiment of the present invention, a first embodiment
The difference from the embodiment is that the blower base 7 is the device frame 1
The upper side 27 of the filter 11 is a cylindrical body provided with a top plate 27A and is provided on the side of the upper side of the upper side 27 (cylindrical surface). That is the point. The upper end of the filter 11 is detachably attached to the lower end of the cylindrical body of the upper lid 27, and the upper lid 27 is attached to the upper end plate 3.
Is stuck to. The waste material intake pipe 28 is connected to an air feeding pipe 29 connected to the outlet of the blower 9.

According to the second embodiment, when the throttle mechanism 14 is fully closed and the drive motor 8 is started to start the operation of the blower 9, the debris having a low specific gravity passes through the transfer pipe to the blower 9 from the suction port 10. After being sucked in, the air passes through the pneumatic tube 29 and the waste material intake tube 28, and flows into the upper lid 27 of the fabric filter 11 from the tangential direction, and the filter 11
While turning along the inner wall surface, it descends and the aperture opening / closing mechanism 14
Deposit on the closed sleeve 15 of. On the other hand, the air from which the debris has been separated and cleaned is discharged into the atmosphere. In this way, when the amount of waste accumulated in the filter reaches a predetermined amount, the diaphragm opening / closing mechanism 14 is fully opened and the waste is discharged.

Since the blower 9, the throttle opening / closing mechanism 14, etc. are operated in the same manner as in the first embodiment, detailed description thereof will be omitted.

In this way, since the waste material flowing into the filter 11 is swirling, the cyclone effect makes it possible to expect good separation efficiency and smooth waste material recovery.

In both of the above embodiments, even if some air leakage occurs in the throttle opening / closing mechanism 14, it does not hinder the collection of waste, but if necessary, the sleeve 15 is a double sleeve. Can be adopted.

The shape of the filter 11 in the present invention is not limited to a cylindrical shape, but may be wide at the bottom, for example, a truncated cone shape, or a cylindrical shape having a diameter-expanded portion at the lower end, and the specific gravity accumulated in the filter 11 is light. It is preferred that the debris can be dumped together at one time.

Further, the movable ring drive means 19 of the aperture opening / closing mechanism 14 can be chain or belt transmission instead of gear transmission.
You may make it switchable to manual operation as needed.

Further, the filter 11 can be equipped with a protective cylinder made of a coarse wire net or a perforated plate on the outside.

(Effects of the Invention) As described above, the present invention is a recovery device in which the dust particles having a light specific gravity are separated by the cloth filter 11 and taken out. The filter 11 has a cylindrical shape with a lid. A diaphragm opening / closing mechanism 14 having a waste material intake port 2 at the upper or upper portion of the filter 11 and a cylindrical flexible sheet material sleeve 15 at the lower end opening of the filter 11.
Since it is characterized by being connected, it is not necessary to perform a secondary filter treatment of the exhaust gas that has passed through the filter 11, and it is not necessary to provide an exhaust filter as in the past, which is extremely economical. It is possible to make the waste passage area of the diaphragm opening / closing mechanism 14 equal to the lower opening of the filter 11, and therefore it is possible to easily and efficiently discharge waste such as fluffy and highly specific waste cotton. Since the whole structure is extremely simple, it can be obtained at low cost,
Further, by intermittently opening and closing the throttle opening / closing mechanism 14, waste is pushed out all at once by the internal pressure, and further, the backwashing effect of the filter 11 can prevent clogging and facilitate maintenance.
