  Preferred embodiments and aspects of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the common part in each figure, and the overlapping description is abbreviate | omitted. The present invention is not limited to the following embodiments and modes, and it goes without saying that various modifications can be made without departing from the gist of the present invention.

1. Apparatus of the Present Invention FIG. 1 is a drawing for explaining a suction / collecting apparatus 1 of the present invention. As shown in FIG. 1A, the suction / collection device 1 of the present invention includes a rigid container portion 2 and a bag body 3 having a mesh accommodated in the rigid container portion 2. The bag body 3 is accommodated so that the opening thereof faces upward. The hard container part 2 of the present invention sucks and collects the collection object in the bag body 3 in the hard container part 2 by being sucked by the suction means, and in some cases, is separated through the mesh of the bag body 3. I do. In addition, the number of the bags 3 accommodated in the hard container portion 2 may be only one, or two or more bags may be stacked. The number of the bags 3 accommodated in the hard container portion 2 can be appropriately changed based on the type of collection object, the size of the grains, and the like. Below, the hard container part 2 and the bag body 3 are demonstrated in detail.

(1) Hard container part 2
The hard container part 2 of the present invention is a box-shaped container manufactured from a hard material. Since the rigid container part 2 is box-shaped, the rigid container part 2 can be easily moved on a truck bed or the like, and suction / collection work can be performed at the site where the collection object is generated. it can.
As described above, since the hard container portion 2 of the present invention is sucked by the suction means, a reduced pressure load is applied to the inside thereof. Therefore, it is preferable that the hard container part 2 is manufactured with the hard material which can resist such decompression load. Specific examples of such hard materials include metal materials such as iron, steel, and stainless steel, and synthetic resin materials. From the viewpoint of ease of processing and durability, it is more preferable that the hard container portion 2 is made of iron and / or steel.

  The rigid container part 2 of the present invention comprises a container main body part 21 and a container lid part 22 (see FIG. 1A). The container lid 22 may be configured to be completely removable from the container body 21. Moreover, the container lid part 22 may be connected to the container main body part 21 using a hinge or the like. As described above, the collection object is aspirated and collected by aspirating the inside of the hard container portion 2 by the aspirating means. Therefore, it is preferable that the container main body portion 21 is closed by the container lid portion 22 and air is not easily leaked from the contact surface between the container main body portion 21 and the container lid portion 22. For example, the container body 21 and the container lid 22 are preferably fixed by the fixing means 23. By using such fixing means 23, air can be prevented from easily leaking from the contact surface between the container main body 21 and the container lid part 22. Moreover, by using the fixing means 23, the container main body 21 and the container lid 22 are firmly fixed, and the resistance force against the reduced pressure applied to the inside of the hard container 2 by suction can be increased. As a specific example of such a fixing means 23, for example, screw fastening with a bolt 232 and a nut 231 as shown in FIG.

The container main body 21 has an outlet 212 connected to suction means via a pipe at the lower part thereof. By operating a suction means connected via a pipe, for example, a pump, a substance such as fine particles or liquid that has passed through the air inside the container main body 21 and the mesh of the bag body 3 via the outlet 212. Is discharged. By providing the outflow port 212 at the lower part of the container main body 21, even when the collection target contains a substance that can pass through the mesh of the bag body 3, for example, fine particles or liquid, these substances can be efficiently transferred to the container main body. 21 can be sucked out.
In the upper part of the container main body 21 and / or the container lid part 22, inflow ports 211 and / or 221 to which pipes can be connected are provided. These inflow ports 211 and 221 are inlets for sucking a collection object, for example, sludge by a suction force through the hard container portion 2 and collecting the sludge in a bag 3 to be described later. The inflow port may be provided in the container lid part 22 as shown in FIG. 1 (a), or may be provided in the upper part of the container main body part 21 as shown in FIG. 1 (c). The container lid 22 and the upper part of the container main body 21 may be provided (not shown).
When the inlet 221 is provided in the container lid part 22, the position of the inlet 221 in the container lid part 22 is not particularly limited, and the collection target that is sucked from the inlet 221 and collected in the bag body 3 is stored in the bag body 3. Any position that can be filled is acceptable. However, since the collection object can be filled into the bag body 3 easily and reliably, it is preferable to provide the inlet 221 at the approximate center of the container lid 22 as shown in FIG.

As shown in FIG. 1 (c), when the inlet 211 is provided at the upper part of the container main body 21, a guide pipe 211 a for transporting the collection object from the inlet 211 to the bag body 3 may be provided. Preferred (see FIG. 1 (d)). However, as will be described later, when the bag 3 is filled with an object to be collected, for example, sludge, when the suction / collection operation is performed using the apparatus of the present invention, the container lid 22 is opened and the sludge is collected. Is taken out of the container body 21 and a new bag 3 is placed in the container body 21. Depending on the work environment, the type of collection object, etc., this work needs to be performed frequently. Therefore, if the container main body 21 is provided with the guide pipe 211a, the replacement work of the bag body 3 may be disturbed. . Therefore, it is more preferable that the inflow port is provided only in the container lid portion 22 in order to smoothly insert and remove the bag body 3.
The outlet 212 and the inlets 221 and 211 can be subjected to any conventional processing such as threading in order to connect the pipes.

In addition, there is no restriction | limiting in particular in the shape of the hard container part 2, Even if it is a cylindrical shape as shown to Fig.1 (a) and (c), quadrangular columnar shape (refer FIG.1 (e)), pentagonal columnar shape (not shown). Or a polygonal columnar shape such as a hexagonal columnar shape (not shown). However, as described above, the hard container portion 2 is subjected to a reduced pressure load by being sucked through the outflow port 212. Therefore, it is more preferable that the shape of the rigid container portion 2 is a cylindrical shape so that it can withstand the load.
Hereinafter, the container main body 21 is provided with an outflow port 212 at the lower part of the container main body 21, the inflow port 221 is provided at substantially the center of the container lid 22, and the shape of the rigid container 2 is cylindrical. And the container lid part 22 is demonstrated.

(1-1) Container body 21
A typical structure of the container main body 21 is shown in FIG. As described above, the container body 21 is provided with the outflow port 212 at the lower part thereof. The outlet 212 can be connected to a pipe, and is connected to the suction means via the pipe.
When the container body 21 and the container lid 22 are fastened by the fixing means 23, for example, the bolt 232 and the nut 231, for example, a contact part 213 with the container lid is provided at the upper end of the container body 21, You may make the screw hole 214 in the said contact part 213 (refer FIG.2 (b)). The container main body 21 has a cavity 215 for accommodating a bag 3 to be described later (see FIG. 2C). A hook or the like for fixing the bag body 3 may be provided on the inner side wall of the container main body 21 as needed (not shown). Note that an outlet pipe 216 may be provided in advance at the outlet 212 in order to facilitate the pipe connection work (see FIG. 2D). The outlet pipe 216 can be subjected to any conventionally used processing such as threading in order to connect the pipes.

  The container main body 21 may have at least one protrusion 217 on its inner wall as needed (see FIG. 3A). In the present invention, the “inner wall” includes not only the inner side wall of the container main body 21 but also the inner side of the bottom plate. The protrusion 217 has at least one hole 217a that penetrates the protrusion 217 (see, for example, FIG. 3B). The size and number of the protrusions 217, the position on the inner wall of the container main body 21 and the size and number of the holes 217a are the size of the container main body 21, the type of the bag 3 accommodated in the container main body 21, and It can be changed as appropriate based on the size, the type of collection object, and the like.

  As described above, a solid and liquid mixture such as sludge may be sucked and collected using the apparatus 1 of the present invention. When such a mixture of solid and liquid is sucked and collected, separation is performed via the mesh of the bag 3. However, for example, when the sludge has a high viscosity, the following problems occur. That is, the sludge having a high viscosity may clog the mesh of the bag 3 and reduce the filtration area of the bag 3 in some cases. In such a case, the bag 3 is stuck to the inner wall of the container main body 21 by continuing the suction operation through the outflow port 212. By the bag body 3 sticking to the inner wall of the container body 21, the sludge suction / collection efficiency and the filtration efficiency are significantly reduced. In contrast, by providing the inner wall of the container main body 21 with the projection 217 as described above, as shown in FIG. 3 (c), the projection 217 against the inner wall of the container main body 21 of the bag 3. Sticking is prevented, and a gap 218 is created between the bag 3 and the inner wall of the container main body 21. The gap 218 communicates with the projection 217 through the hole 217a. Accordingly, since the filtration area is secured by the gap 218 formed around the protrusion 217, it is possible to suck and collect sludge with high viscosity with higher efficiency compared to the case where the protrusion 217 is not provided. Can do.

  The direction of the protrusion 217 provided on the inner wall of the container main body 21 is not particularly limited, and as shown in FIG. 3B, the hole 217a may be provided so as to penetrate in the vertical direction. Moreover, as shown in FIG.3 (d), you may provide so that the hole 217a may penetrate in a horizontal direction. As shown in FIGS. (E) and (f), the protrusion 217 may be provided in an oblique direction with respect to the inner wall of the container main body 21. As shown in FIG. 3, only one protrusion 217 can be provided on the inner wall of the container main body 21, or two or more protrusions 217 can be provided as shown in FIG. As shown in FIG. 4B, the protrusion 217 can be provided so as to draw a spiral on the inner wall of the container main body 21. As shown in FIG. 4C, one or more protrusions 217 extending in the vertical direction can be provided on the side wall of the container main body 21. Moreover, as shown in FIG.4 (d), the 1 or more protrusion part 217 connected from the end of the side wall of the container main-body part 21 to the other side through the bottom plate can also be provided.

  Furthermore, the protrusion 217 may form a ring along the inner wall shape of the container body 21 as shown in FIG. The shape of the ring is a shape along the shape of the hard container part 2. For example, when the protruding portion 217 forms a ring and the shape of the rigid container portion 2 is cylindrical, the shape of the protruding portion 217 is a circular ring (see FIG. 5A). In addition, when the protruding portion 217 forms a ring and the shape of the rigid container portion 2 is a polygonal column shape, for example, a rectangular column shape, the shape of the protruding portion 217 is a rectangular ring (not shown). The durability of the rigid container portion 2 is improved by the protrusion 217 having a ring shape. That is, when the decompression load is applied to the hard container part 2 through the outflow port 212, the inner wall of the container main body part 21 receives a pressure that contracts in the inner direction. Since the protrusion 217 has a ring shape, resistance to the pressure contracting in the inner direction is increased, so that the durability of the hard container portion 2 is further improved. When the protrusion 217 has a ring shape, the protrusion 217 is arranged in a substantially horizontal direction (for example, the protrusion 217 is substantially perpendicular to the inner wall of the container main body 21 and substantially parallel to the bottom surface of the container main body 21. The durability of the container body 21 can be further improved.

  Further, as shown in FIG. 5B, a plurality of ring-shaped protrusions 217 may be provided. By increasing the number of ring-shaped protrusions 217 in this way, more gaps 218 are created to prevent a reduction in filtration efficiency (see FIG. 5C), and the durability of the hard container portion 2 is further improved. It is possible to make it. Further, in the case where a plurality of ring-shaped protrusions 217 are provided, the durability of the rigid container portion 2 can be further improved. Therefore, the protrusions are arranged in a substantially horizontal direction (for example, the protrusions 217 with respect to the inner wall of the container main body 21). It is more preferable that the projections 217 be substantially parallel to each other at substantially right angles and substantially parallel to the bottom surface of the container body 21. When the protrusion 217 has a ring shape, the number of rings, the thickness and width of the ring, the size of the hole 217a opened in the protrusion 217, the number of the holes 217a, etc. The type can be appropriately changed based on the type of the object, the type and size of the bag 3 accommodated in the container main body 21, the durability required for the container main body 21, and the like.

The protruding portion 217 can be manufactured using, for example, a metal material such as iron, steel, or stainless steel, or a synthetic resin material.
There are no particular restrictions on the method used when the protrusion 217 is provided inside the container main body 21. For example, the protrusion 217 may be fixed by any fixing method conventionally used, such as welding, bonding using an adhesive, and screwing. Is also possible. However, as described above, the hard container portion 2 is preferably sealed as much as possible. Furthermore, it is preferable that the protrusions 217 are more firmly fixed so that the gaps 218 can be surely created and higher resistance to reduced pressure is provided. Therefore, for example, when the hard container part 2 is made of iron and / or steel, it is more preferable to fix the protrusion part 217 made of a metal material to the inner wall of the container main body part 21 by welding.

  It is more preferable that the container main body 21 has a barrier 219 against the bag body 3 in front of the outlet 212 in the inside thereof as required (see FIGS. 6A and 6B). As described above, the rigid container portion 2 is sucked and depressurized via the outflow port 212. If the suction force is strong, the bag 3 may be pulled to close the outflow port 212, and the suction / collection efficiency of the collection target may be reduced. In such a case, the presence of the barrier 219 against the bag body 3 before the outflow port 212 inside the container main body 21 can prevent the bag body 3 from blocking the outflow port 212. Such a barrier 219 may be a simple plate, but may have a barrier hole 219a as shown in FIG. By having such a hole 219a of the barrier, even when the bag body 3 sticks to the barrier 219, the suction through the hole 219a and the filtration by the bag body 3 can be continued. Can be secured. There may be only one barrier hole 219a as shown in FIG. 6C, or a plurality of holes as shown in FIG. 6D. In addition, by adjusting the position of the barrier 219, the barrier 219 may function not only as a barrier for the bag body 3, but also as a protrusion 217.

The barrier 219 can be made of, for example, a metal material such as iron, steel, or stainless steel, or a synthetic resin material.
The method for fixing the barrier 219 to the container body 21 is not particularly limited, and can be fixed by any conventional fixing method such as welding, bonding using an adhesive, and screwing. . However, as described above, the rigid container portion 2 is preferably sealed as much as possible, and it is preferable that the barrier 219 is firmly fixed so that the pressure from the bag body 3 can be surely resisted. Therefore, for example, when the hard container part 2 is made of iron and / or steel, it is more preferable to fix the barrier 219 made of a metal material to the inner wall of the container body part 21 by welding. Further, as shown in FIG. 6 (e), the upper portion of the barrier 219 is supported by a protrusion 217 provided on the side wall of the container main body 21, thereby fixing the barrier 219 more firmly inside the container main body 21. You can also.

(1-2) Container lid 22
FIG. 7 is a view showing an embodiment of the container lid portion 22. As described above, in the present embodiment, the inflow port 221 capable of connecting a pipe is provided in the approximate center of the container lid portion 22. The collection target can be sucked and collected using a pipe connected to the inlet 221 by the suction force via the outlet 212.
A viewing window 222 may be provided on the container lid 22. The observation window 222 is, for example, a glass or resin transparent window provided in a part of the container lid portion 22. By providing such a viewing window 222, the amount of the collection target filled in the bag 3 can be visually confirmed without removing the container lid 22 from the container body 21. When visually confirming that the bag 3 is filled with the collection object, the suction / collection operation is temporarily suspended, the container lid part 22 is removed from the container body part 21, and the collection object is filled. The bag body 3 and the new bag body 3 can be interchanged.

  An air wiper 223 may be provided in the vicinity of the observation window 222. The air wiper 223 includes a pipe 223a extending from the surface of the container lid portion 22 to the back surface of the observation window 222, an opening / closing valve 223b and a cock 223c provided in the pipe (see FIGS. 7A to 7C). . The air wiper 223 is used as follows. For example, when the inner surface of the inspection window 222 is contaminated by a collection object such as sludge splashes, the cock 223c is twisted to open the open / close valve 223b. When the on-off valve 223b is opened, air enters the inside of the hard container part 2 through the pipe 223a with a momentum corresponding to the reduced pressure applied to the hard container part 2. At this time, the air that has entered the hard container portion 2 passes through the inner surface of the observation window 222 vigorously, thereby removing sludge droplets adhering to the inner surface of the observation window 222. With such an air wiper 223, even if the inside of the inspection window 222 is contaminated with the collection object, the inspection window 222 can be cleaned without removing the container lid 22 from the container body 21, and the suction / collection operation is interrupted. Can continue without.

A pressure gauge 224 may be provided on the container lid portion 22. Even when a pressure reducing load exceeding the durability of the hard container portion 2 is applied by the pressure gauge 224, the fact can be easily confirmed. Further, by providing the relief valve 225 in the container lid portion 22, when a decompression load exceeding the durability of the rigid container portion 2 is applied, the load can be quickly eliminated by opening the relief valve 225.
Further, when the container main body 21 and the container lid 22 are fastened by the fixing means 23, for example, the bolt 232 and the nut 231, for example, it is preferable to make a screw hole 226 in the container lid 22.
Note that an inlet pipe 227 may be provided in advance at the inlet 221 in order to facilitate the pipe connection work (see FIG. 7D). The inlet pipe 227 can be subjected to any conventionally used processing such as threading to connect the pipes.

  As described above, it is preferable that the container body 21 and the container lid 22 can be sealed as much as possible. Therefore, it is preferable that a packing 24 made of an elastic material is provided on the surface where the container main body 21 and the container lid 22 come into contact (see FIG. 8). Examples of the elastic material include natural rubber and synthetic rubber. The packing 24 can be provided only on the container body 21 side, can be provided only on the container lid 22 side, or can be provided on both the container body 21 side and the container lid 22 side.

(2) Bag 3
The bag body 3 of the present invention is a bag body having a mesh, and is used by being housed inside the hard container portion 2. The bag body 3 has an opening for receiving the collection object sucked through the inflow port 221. The size of the opening can be changed as appropriate based on the size of the hard container 2, the type of collection object, and the like. In the present invention, “mesh” means a hole of a sheet such as cloth through which liquid such as air and water and fine particles can pass. Accordingly, the “mesh” in the present invention includes not only meshes formed when yarns, cloths, resin sheets and the like cut into pieces are knitted but also interstices between fibers entangled in the nonwoven fabric. The mesh size of the mesh can be changed as appropriate based on the type of collection object, the size of the grains contained in the collection object, and the like.
The mesh does not need to be present in the entire bag body 3, and the mesh may be applied only to a part of the bag body 3. However, as described above, the collection target is sucked and collected from the inlet 221 through the outlet 212 and is stored in the bag 3. In addition, when sucking and collecting sludge, for example, a mixture of solid and liquid, the solid and liquid (in some cases, a mixture of fine particles passing through the mesh and liquid) are passed through the bag 3. Are separated. Therefore, the mesh applied to the bag body 3 is preferably applied over the widest possible range, preferably over the entire bag body 3. Since the mesh is applied to the entire bag body 3, a larger amount of collection object is obtained while continuing separation of solid and liquid (in some cases, a mixture of fine particles and liquid that have passed through the mesh). Can be accommodated.
The material of the bag 3 may be any material provided that it can withstand the weight of the collected collection object. Examples of these materials include not only natural materials such as cotton and hemp but also synthetic resin materials such as polypropylene and polyethylene.

  Moreover, it is preferable that the bag 3 is flexible. Since the bag body 3 is flexible, the bag body 3 can be stored compactly before the bag body 3 is used. Further, since the bag body 3 is flexible, it can be handled more easily when the bag body 3 filled with the collection object is transported. Furthermore, by using the flexible bag 3 and the container main body 21 provided with the protrusions 217 in combination, the gap 218 can be created more easily, so that the efficiency of the suction / collection work can be further increased.

  A preferable example of the bag body 3 is a flexible container bag, for example. The flexible container bag is a bag body mainly made of a mesh base made of a synthetic resin material. Moreover, it is generally easy to obtain and there are many that are provided with a handle for hanging with a crane or the like. Furthermore, the flexible container bag has appropriate flexibility suitable for use as the bag body 3 of the present invention. Therefore, the flexible container bag is suitable for use as the bag body 3 of the present invention.

The inventor has also invented a new flexible container bag that can be suitably used as the bag body 3 of the present invention. Below, the flexible container bag of this invention is demonstrated by comparing the conventional flexible container bag and the flexible container bag of this invention.
A conventional flexible container bag is shown in FIG. The conventional flexible container bag is a combination of a bag body main body 31 and a bag lid 32, and a handle 33 is provided as necessary. Usually, the length P of the upper peripheral edge of the bag body 31 and the length Q of the upper peripheral edge of the bag lid 32 are the same.

  On the other hand, in the flexible container bag of the present invention shown in FIG. 9B, the length P of the upper peripheral edge of the bag body 31 and the length Q of the upper peripheral edge of the bag lid 32 are shown. However, there is a relationship of P <Q. 9 (b-1) is a front view of the flexible container bag of the present invention, (b-2) is the right side view, (b-3) is the plan view, and (b-4). Represents the bottom view. The left side view is the same as the right side view, and the rear view is the same as the front view, and is therefore omitted.

A handle 33 may be provided on the bag body 31 as necessary.
Moreover, the bag body 3 of this invention may have the taking-out port 34 in the lower part as needed (refer FIG. 10). By having such a take-out port 34, the collection object can be discharged from the lower part of the bag 3 in a lifted state. 10A is a perspective view of the flexible container bag of the present invention having the take-out port 34, FIG. 10B is a front view thereof, FIG. 10C is a right side view thereof, and FIG. (E) represents the bottom view. The left side view is the same as the right side view, and the rear view is the same as the front view, and is therefore omitted.

  In the flexible container bag of the present invention, the length P of the upper peripheral edge of the bag body 31 and the length Q of the upper peripheral edge of the bag lid 32 are in a relationship of P <Q. The effect is demonstrated. That is, since the bag body lid portion 32 is spread outward, the end of the bag body lid portion 32 can be sandwiched between the container body portion 21 and the container lid portion 22 (see FIG. 11A). . Thus, the bag body 3 is firmly fixed in the rigid container portion 2 by sandwiching the end of the bag body lid portion 32 between the container main body portion 21 and the container lid portion 22. Further, since the bag lid portion 32 also has a mesh, even if the bag body main portion 31 is filled with the collection object, the mesh of the bag lid portion 32 (the dotted line portion 32 in FIG. 11A). ) Ensures a filtration area. Further, by using the flexible container bag of the present invention together with the container main body 21 having the projections 217, a large number of gaps 218 can be created (see FIG. 11B), and a larger filtration area is secured. it can. The difference between the length P of the upper peripheral edge of the bag body 31 and the length Q of the upper peripheral edge of the bag lid 32 is, for example, the length P of the upper peripheral edge of the bag body 31. , The length Q of the peripheral edge at the upper end of the bag lid portion 32 is, for example, 1.2 to 2.0, preferably 1.2 to 1.8, and more preferably 1.2 to 1. By setting it to 5, a flexible container bag that is easier to handle can be obtained while obtaining the above effects.

2. Suction / collection system of the present invention The suction / collection system of the present invention is a system including the suction / collection apparatus 1 and a suction means.
FIG. 12 shows an example of the suction / collection system of the present invention. In the suction / collection system of FIG. 12, a collection pipe 4 used when an operator collects a collection target is connected to the inlet 221 of the suction / collection apparatus 1 of the present invention. A suction pipe 5 for connecting the suction pump 7 serving as a suction means and the suction / collection device 1 is connected to the outlet 212 of the suction / collection device 1. A dust collector 6 is provided between the suction / collection device 1 and the suction pump 7 as necessary. The suction / collection system described in FIG. 12 is suitable when, for example, a solid that does not contain a liquid, such as gravel or powder, is suctioned / collected. The specific operation is as follows. By operating the suction pump 7, the suction pump 7 sucks the inside of the suction / collection device 1 through the suction pipe 5. The collection object is sucked from the inlet 41 of the collection pipe 4 by the suction force via the suction / collection device 1. The collection object sucked in by the collection pipe 4 reaches the bag body 3 disposed therein via the inlet 221 of the suction / collection device 1. Only the air is sucked out from the outflow port 212 by the mesh ground of the bag body 3, and only the collection object remains inside the bag body 3. Note that the fine powder that passes through the mesh of the bag 3 is collected by the dust collector 6.

  FIG. 13 shows another example of the suction / collection system of the present invention. In the suction / collection system of FIG. 13, a collection pipe 4 used when an operator collects a collection target is connected to the inlet 221 of the suction / collection apparatus 1 of the present invention. A suction pipe 5 for connecting the vacuum car 8 as a suction means and the suction / collection device 1 is connected to the outlet 212 of the suction / collection device 1. The suction / collection system shown in FIG. 13 sucks / collects not only a liquid-free solid, such as gravel or powder, but also a mixture of liquid and solid, such as sludge. In some cases.

  The specific operation is as follows. By operating the vacuum car 8, the vacuum car 8 sucks the inside of the suction / collection device 1 through the suction pipe 5. The collection target is sucked from the inlet 41 of the collection pipe 4 by the suction force via the suction / collection device 1. The collection object sucked in by the collection pipe 4 reaches the bag body 3 disposed therein via the inlet 221 of the suction / collection device 1. The air and / or liquid contained in the collection object (in some cases, a mixture of fine particles passing through the mesh and liquid) is filtered by the mesh of the bag 3 and sucked out from the outlet 212. It is. The sucked air and / or liquid (in some cases, a mixture of fine particles and liquid that have passed through the mesh eye) is collected in the vacuum car 8 via the suction pipe 5. Accordingly, only the solid collection object remains in the bag 3.

  By using the system of the present invention, it is possible to suck and collect the collection object directly at the site where the collection object exists. Furthermore, even if the object to be collected is a mixture of a liquid and a solid, the system of the present invention allows the liquid (in some cases, a mixture of fine particles passing through the mesh and liquid) to be solid. Separation is possible, and the volume of collection objects can be easily reduced. Moreover, since the system of the present invention can perform suction, collection, and separation using a closed system, it does not pollute the site or workers.

3. Aspiration / collection method of the present invention The aspiration / collection method of the present invention is performed using the apparatus or system of the present invention.
The collection object to be sucked and collected by the method of the present invention is not particularly limited as long as it is a substance that can be sucked using a pipe. Examples of such substances include not only solids such as dust accumulated in ducts, but also mixtures of solids and liquids such as sludge, cakes, rivers and sea sediments. In addition, the method of the present invention is not limited to wastes and the like, and can be used, for example, when collecting and filling powders manufactured in factories that manufacture powders, that is, powders as products. .

  FIG. 14 is a flowchart for explaining the steps of the suction / collection method of the present invention. First, the bag body 3 is placed in the container main body 21 of the hard container 2, and the container main body 21 is closed by the container lid 22. The suction means connected to the hard container part 2 is operated to fill the bag 3 with the collection object. When the bag 3 is filled with the collection object, the container lid 22 is removed from the container body 21 and the bag 3 filled with the collection object is taken out from the container body 21. Next, a new bag 3 is placed in the container body 21. Even if the collection object is a mixture of a liquid and a solid, the bag 3 filled with the collection object has a liquid (in some cases, a mixture of fine particles and liquid that have passed through mesh eyes). It is filtered and removed by the bag 3. Therefore, the bag 3 filled with the collection object can be easily carried out by a truck or the like without polluting the site. When the collection object is waste, the carried bag 3 is carried to a processing factory or the like and processed at the factory. When the collection target is a product manufactured at a factory or the like, the carried bag 3 is shipped to a customer or the like. In the method of the present invention, by collecting the cycle shown in FIG. 14, the collection target can be collected continuously with very high efficiency.

  According to the present invention, not only a collection object consisting of only a solid such as a powder, but also a mixture of a liquid and a solid such as sludge is moved to the site where the object is generated, and the site is not easily contaminated. Can now be collected. In addition, according to the present invention, not only waste generated in a factory such as sludge and cake, but also products such as produced powder can be easily collected with high efficiency without adversely affecting workers.
