Prior art 2 also has the same problem as described above.
Further, according to the prior art 3, since a facility such as a silo equipped with a hopper is required, the facility becomes large and the facility cost is increased.

  The present invention has been made in view of the above circumstances, and one object of the present invention is to solve the above-mentioned problems of the prior arts 1 and 2, and to remove dust, dust and other desired substances. It is an object of the present invention to provide a suction collecting device that can easily and efficiently collect good.

  Another object of the present invention is to solve the above-mentioned problems of the prior art 3, and to easily and smoothly remove grains, flours and other desired substances without providing facilities such as silos and hoppers. It is an object of the present invention to provide a suction collection device that can collect well.

In order to achieve the above object, one of the present inventions (first invention) is a suction collection device for sucking and collecting a desired substance,
An airtight housing having an opening and an opening / closing means capable of opening and closing the opening and closing the airtightness;
A suction pressure reducing means for sucking and reducing the inside of the housing;

  10 and 11 show a suction collection device of still another embodiment (Embodiment 4) of the present invention. The fourth embodiment is characterized by a configuration including a cyclone separator (machine) 8.

  In the present invention, as described above, the cyclonic separator (machine) uses a centrifugal force to separate and recover air and dust (dust etc.), that is, utilizing the principle of the cyclone. It is a gas / solid (solid matter) separation device that collects solid matter by centrifuging gas (air) and solid matter by utilizing a dust collector (cyclone dust collector) and other cyclone principles. Various types of known cyclone separators 8 can be employed. It is also possible to use various existing cyclone dust collectors and other various types of cyclone separators.

  The cyclonic separator (machine) 8 according to the fourth embodiment includes a cyclone cylinder portion 80, a suction port portion 81, an air discharge port portion 82 (a decompression suction port portion), and a solid matter discharge port portion 83. .

  The suction port portion 81 is provided at the upper end portion of the cylindrical body portion 80 so as to be along the circumferential tangent line of the inner diameter cross section of the cylindrical body portion 80. The air discharge port portion 82 is provided at a substantially central portion of the upper end portion of the cylindrical body portion 80. Further, the solid discharge port 83 is formed at the lower end of the cylindrical body 80.

The cyclonic separator of the fourth embodiment has the above configuration. And by making the inside of the cyclone cylinder 80 into a negative pressure, for example, in the case of a dust collector, the air and dust sucked from the suction port form a spiral airflow in the cylinder and has a high specific gravity. Dust or the like is centrifuged and falls along the inner wall of the cylindrical body portion, is discharged from the discharge port portion 83, and air is discharged from the air discharge port portion 82.
Also, in the case of cereals, flours and other various substances, it is configured to be centrifuged with air in the cylindrical part as described above, and the substances such as cereals are dropped and discharged from the solid matter outlet. ing.

Thereby, by driving the suction pressure reducing means 2, the pressure in the cyclone cylinder 80 is sucked and reduced (negative pressure).

When the inside of the cylindrical body 80 becomes negative pressure, a suction force is generated in the suction port 81, and air, dust, trash, grains, flour and other various substances sucked from the suction port 81 are described above. As described above, centrifugal separation is performed in the cylindrical body portion 80, and dust, dust, grains and other various substances are sequentially dropped and discharged from the discharge port portion 83.
Further, in the above process, the suction force by the suction pressure reducing means 2 causes the cylindrical body portion 80 to become a pressure resistance (resistance means), resulting in a pressure loss.

Moreover, the container body is fixed to the lid and suspended, and the setting is completed. By driving the suction pressure reducing means 2 in this state, for example, in the case of a dust collector, as described above, the air and dust sucked from the suction port portion are separated in the cylindrical body portion, and the dust falls, The product is discharged from the discharge port 83 and sequentially filled into the bag-like body and collected.

  As described above, dust and the like are separated from air in the cyclone cylinder and collected in the bag-like body. In order to dispose of dust collected in the bag-like body, the suction pressure reducing means is stopped. Then, the lock of the fixture is released and the container body 10 is lowered. Then, the fixing by the fixing means 40 is released, and the bag-like body filled with dust or the like is lowered into the container body and accommodated.

  After the above operation is completed, the post-processing operation is performed such as moving the container body to a desired place, taking out the bag-shaped body filled with dust and the like from the container body, and disposing it. Thereby, the dust etc. which fall from a solid substance discharge port part are filled and collected in a bag-shaped body, and post-processing work etc. can be performed smoothly.

  On the other hand, when collecting cereals, flours and other desired substances, the housing is set by operating in the same manner as described above. Further, a hose or other material suction tube member (not shown) is connected to the suction port.

  The suction pressure reducing means 2 is driven in the above state. Then, the desired substance (object) is transported through the tube member and sucked into the cylindrical body portion 80 through the tube member by causing the distal end side of the tube member to face the desired object portion. Then, the target object is separated (centrifugated) from the air and dropped in the cylindrical body portion, and is discharged from the discharge port portion 83 and sequentially filled into the bag-like body and collected.

  After a predetermined amount of the target substance is collected in the bag-like body as described above, the suction decompression means 2 is stopped. Then, similarly to the above, the lock of the fixing metal is released and the fixing by the fixing means is released, and the bag-like body filled with the target object is lowered into the container body and accommodated.

  After completion of the above operation, the post-processing operation such as moving the container body to a desired location, taking out the bag-like body filled with the object from the container body, and storing it in the desired location is performed. By repeating the above operation, a desired substance can be sucked and separated, and the separated product (separated product) can be collected.

  Although not disclosed in the drawings, when performing the above-described operation, the bag-shaped body is filled by performing the above-described operation with a meter (such as a weight sensor) attached to an appropriate portion of the housing. While measuring the volume (amount) of a substance, it can be filled into a bag and collected.

  According to the suction collection device of the fourth embodiment, in addition to the effects (1) to (7) described for the suction collection device of the first embodiment, from the solid matter discharge port of the cyclone separator (machine). The discharged dust and the like can be collected smoothly and satisfactorily in the bag-like body.
