Preferred embodiments and embodiments of the present invention will be described with reference to the drawings. In addition, the same reference numerals are given to the common parts in each figure, and duplicate description is omitted. Further, it is needless to say that the present invention is not limited to the following embodiments and embodiments, and various modifications can be made without departing from the gist of the present invention.

1. 1. The device of the present invention FIG. 1 is a drawing for explaining the suction / collection device 1 of the present invention. As shown in FIG. 1A, the suction / collection device 1 of the present invention includes a hard container portion 2 and a bag body 3 having a mesh housed in the hard container portion 2. The bag body 3 is housed so that its opening faces upward. The hard container portion 2 of the present invention sucks and collects the object to be collected into the bag body 3 in the hard container portion 2 by being sucked by the suction means, and in some cases, separates through the mesh of the bag body 3. I do. The number of bags 3 housed in the hard container 2 may be only one, or two or more bags may be stacked. The number of bags 3 housed in the hard container portion 2 can be appropriately changed based on the type of the object to be collected, the size of the grains, and the like. The hard container portion 2 and the bag body 3 will be described in detail below.

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

The hard container portion 2 of the present invention includes a container main body portion 21 and a container lid portion 22 (see FIG. 1A). The container lid portion 22 may have a structure that can be completely removed from the container main body portion 21. Further, the container lid portion 22 may be connected to the container main body portion 21 by using a hinge or the like. As described above, the object to be collected is sucked and collected by sucking the inside of the hard container portion 2 by the suction means. Therefore, it is preferable that the container body 21 is closed by the container lid 22 and the structure is such that air does not easily leak from the contact surface between the container body 21 and the container lid 22. For example, it is preferable to fix the container body 21 and the container lid 22 with the fixing means 23. By using such a fixing means 23, it is possible to easily prevent air from leaking from the contact surface between the container main body portion 21 and the container lid portion 22. Further, by using the fixing means 23, the container main body 21 and the container lid 22 are firmly fixed, and the resistance to the depressurizing pressure applied to the inside of the hard container 2 by suction can be increased. Specific examples of such fixing means 23 include screw fastening with bolts 232 and nuts 231 as shown in FIG. 1 (b).

The container body 21 has an outlet 212 at its lower portion, which is connected to the suction means via a pipe. By operating a suction means connected via a pipe, for example, a pump, air inside the container body 21 and a substance that has passed through the mesh mesh of the bag 3 through the outlet 212, for example, fine particles or liquid. Is discharged. By providing the outlet 212 at the lower part of the container body 21, even if the object to be collected contains substances that can pass through the mesh of the bag 3, for example, fine particles or liquids, these substances can be efficiently collected in the container body. It can be sucked out from 21.
In the upper part of the container body 21 and / or the container lid 22, an inflow port 211 and / or 221 to which a pipe 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 sludge in a bag body 3 described later. The inflow port may be provided in the container lid portion 22 as shown in FIG. 1 (a), or may be provided in the upper portion of the container main body portion 21 as shown in FIG. 1 (c). , It may be provided on both the container lid portion 22 and the upper portion of the container main body portion 21 (not shown).
When the inflow port 221 is provided in the container lid portion 22, the position of the inflow port 221 in the container lid portion 22 is not particularly limited, and the collection object sucked from the inflow port 221 and collected in the bag body 3 is in the bag body 3. Any position can be filled. However, since the bag 3 can be easily and reliably filled with the object to be collected, it is preferable to provide the inflow port 221 substantially in the center of the container lid 22 as shown in FIG. 1 (a).

As shown in FIG. 1 (c), when the inflow port 211 is provided in the upper part of the container main body 21, the guide pipe 211a for transporting the object to be collected from the inflow port 211 to the bag 3 may be provided. Preferred (see FIG. 1 (d)). However, as will be described later, when the bag body 3 is filled with the object to be collected, for example, sludge, when the suction / collection work is performed using the apparatus of the present invention, the container lid 22 is opened and the sludge is opened. The bag body 3 containing the bag 3 is taken out from the container body 21 and a new bag 3 is put into the container body 21. Since this work needs to be performed frequently depending on the work environment and the type of the object to be collected, if the guide pipe 211a is provided in the container main body 21, there is a possibility that the replacement work of the bag 3 may be hindered. .. Therefore, it is more preferable that the inflow port is provided only in the container lid portion 22 in order to allow the bag body 3 to be taken in and out more smoothly.
The outlet 212, the inlet 221 and 211 can be subjected to any conventionally used processing such as thread cutting in order to connect the pipes.

The shape of the hard container portion 2 is not particularly limited, and even if it is cylindrical as shown in FIGS. 1 (a) and 1 (c), it is a quadrangular columnar (see FIG. 1 (e)) or a pentagonal columnar (shown in the figure). It may be a polygonal cylinder such as a hexagonal cylinder (not shown). However, as described above, the hard container portion 2 is subjected to a decompression load due to being sucked through the outlet 212. Therefore, it is more preferable that the shape of the hard container portion 2 is cylindrical so that it can withstand the load.
Hereinafter, the container main body 21 is taken as an example of a hard container 2 having an outflow port 212 at the bottom of the container main body 21 and an inflow port 221 substantially at the center of the container lid 22 and having a cylindrical shape. And the container lid portion 22 will be described.

(1-1) Container body 21
FIG. 2A shows a typical structure of the container main body 21. As described above, the container main body 21 is provided with an outlet 212 at the lower portion 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 portion 213 with the container lid is provided at the upper end of the container body 21. A screw hole 214 may be formed in the contact portion 213 (see FIG. 2B). The container main body 21 has a cavity 215 for accommodating the bag body 3 described later (see FIG. 2 (c)). If necessary, a hook or the like for fixing the bag 3 may be provided on the inner side wall of the container body 21 (not shown). In addition, in order to proceed with the pipe connection work more smoothly, the outlet pipe 216 may be provided in advance at the outlet 212 (see FIG. 2D). The outlet pipe 216 can be subjected to any conventionally used processing such as thread cutting to connect the pipes.

The container body 21 may have at least one protrusion 217 on its inner wall, if necessary (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 inside of the bottom plate. The protrusion 217 has at least one hole 217a penetrating 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 body 21, the size and the number of the holes 217a, etc. are the size of the container body 21, the type of the bag 3 housed in the container body 21, and the number of the holes 217a. It can be changed as appropriate based on the size, type of object to be collected, etc.

As described above, the apparatus 1 of the present invention may be used to suck and collect a mixture of solid and liquid such as sludge. When sucking and collecting such a mixture of solid and liquid, separation is performed via the mesh of the bag body 3. However, for example, when the viscosity of sludge is high, the following problems occur. That is, sludge having a high viscosity may clog the mesh of the bag body 3 and reduce the filtration area of the bag body 3. In such a case, the bag body 3 sticks to the inner wall of the container main body 21 because the suction work via the outlet 212 is continued. When the bag body 3 sticks to the inner wall of the container main body 21, the sludge suction / collection efficiency and the filtration efficiency are significantly reduced. On the other hand, by providing the protrusion 217 as described above on the inner wall of the container main body 21, the protrusion 217 relates to the inner wall of the container main body 21 of the bag body 3 as shown in FIG. 3 (c). It prevents sticking and creates a gap 218 between the bag body 3 and the inner wall of the container body 21. The gap 218 communicates with the hole 217a of the protrusion 217. Therefore, since the filtration area is secured by the gap 218 formed around the protrusion 217, sludge and the like having high viscosity can be sucked and collected with higher efficiency as compared with the case where the protrusion 217 is not provided. Can be done.

The direction of the protrusion 217 provided on the inner wall of the container main body 21 is not particularly limited, and the hole 217a may be provided so as to penetrate in the vertical direction as shown in FIG. 3 (b). Further, as shown in FIG. 3D, the hole 217a may be provided so as to penetrate in the 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 may be provided on the inner wall of the container main body 21, or two or more may be provided as shown in FIG. 4 (a). As shown in FIG. 4B, the protrusion 217 may 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 vertically extending protrusions 217 may be provided on the side wall of the container main body 21. Further, as shown in FIG. 4D, one or more protrusions 217 connected from one end of the side wall of the container main body 21 to the opposite side through the bottom plate may be provided.

Further, as shown in FIG. 5A, the protrusion 217 may form a ring along the shape of the inner wall of the container body 21. The shape of the ring follows the shape of the hard container portion 2. For example, when the protrusion 217 forms a ring and the shape of the hard container 2 is cylindrical, the shape of the protrusion 217 is a circular ring (see FIG. 5A). Further, when the protrusion 217 forms a ring and the shape of the hard container portion 2 is a polygonal columnar shape, for example, a quadrangular columnar shape, the shape of the protrusion portion 217 is a quadrangular ring (not shown). Since the protrusion 217 has a ring shape, the durability of the hard container 2 is improved. That is, when a decompression load is applied to the hard container portion 2 via the outlet 212, the inner wall of the container main body portion 21 receives a pressure that contracts in the inward direction. Since the protrusion 217 has a ring shape, the resistance to the pressure contracting in the internal direction is increased, so that the durability of the hard container portion 2 is further improved. When the protrusion 217 is in the shape of a ring, the protrusion 217 is substantially horizontal (for example, the protrusion 217 is substantially perpendicular to the inner wall of the container body 21 and substantially parallel to the bottom surface of the container body 21). By doing so, the durability of the container main 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 decrease in filtration efficiency (see FIG. 5 (c)), and the durability of the hard container portion 2 is further improved. It is possible to make it. Further, when a plurality of ring-shaped protrusions 217 are provided, the durability of the hard container portion 2 can be further improved, so that each protrusion is provided in a substantially horizontal direction (for example, each protrusion 217 is relative to the inner wall of the container main body 21). It is more preferable that the protrusions 217 are substantially parallel to each other at a substantially right angle and substantially parallel to the bottom surface of the container body 21). When the protrusion 217 is in the shape of a ring, the number of rings, the thickness and width of the ring, the size of the hole 217a formed in the protrusion 217, the number of holes 217a, etc. are the size of the container body 21 and the collection. It can be appropriately changed based on the type of the object, the type and size of the bag 3 housed in the container body 21, the durability required for the container body 21, and the like.

The protrusion 217 can be manufactured from, for example, a metal material such as iron, steel, or stainless steel, a synthetic resin material, or the like.
There is no particular limitation on the method for providing the protrusion 217 inside the container main body 21, and the protrusion 217 is fixed by any conventional fixing method such as welding, adhesion using an adhesive, and screwing. Is also possible. However, as described above, it is preferable that the hard container portion 2 is sealed as much as possible. Further, it is preferable that the protrusion 217 is more firmly fixed so that the gap 218 can be reliably created and a higher resistance to the depressurizing pressure can be provided. Therefore, for example, when the hard container portion 2 is made of iron and / or steel, it is more preferable to fix the protrusion 217 made of a metal material to the inner wall of the container main body portion 21 by welding.

It is more preferable that the container body 21 has a barrier 219 against the bag 3 inside the container body 21 in front of the outlet 212 (see FIGS. 6 (a) and 6 (b)). As described above, the hard container portion 2 is sucked and depressurized via the outlet 212. If the suction force is strong, the bag body 3 may be pulled to block the outlet 212, which may reduce the suction / collection efficiency of the object to be collected. In such a case, the presence of the barrier 219 for the bag 3 in front of the outlet 212 inside the container body 21 can prevent the bag 3 from blocking the outlet 212. Such a barrier 219 may be a simple plate, but may have a hole 219a of the barrier as shown in FIG. 6 (c). By having the hole 219a of such a barrier, even when the bag 3 sticks to the barrier 219, it can be sucked through the hole 219a and the filtration by the bag 3 can be continued, so that the area of the hole 219a is filtered. Can be secured as. The barrier hole 219a may be only one as shown in FIG. 6 (c), or may be a plurality of holes as shown in FIG. 6 (d). By adjusting the position of the barrier 219, the barrier 219 may function not only as a barrier to the bag 3 but also as a protrusion 217.

The barrier 219 can be manufactured from, for example, a metal material such as iron, steel, or stainless steel, a synthetic resin material, or the like.
There is no particular limitation on the method of fixing the barrier 219 to the container main body 21, and it is possible to fix the barrier 219 by any conventional fixing method such as welding, adhesion using an adhesive, and screwing. .. However, as described above, it is preferable that the hard container portion 2 is sealed as much as possible, and it is preferable that the barrier 219 is firmly fixed so as to reliably resist the pressure from the bag body 3. Therefore, for example, when the hard container portion 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 main body portion 21 by welding. Further, as shown in FIG. 6 (e), the barrier 219 is more firmly fixed to the inside of the container main body 21 by supporting the upper portion of the barrier 219 with the protrusion 217 provided on the side wall of the container main body 21. You can also.

(1-2) Container lid 22
FIG. 7 is a drawing showing one form of the container lid portion 22. As described above, in the present embodiment, an inflow port 221 to which a pipe can be connected is provided substantially in the center of the container lid portion 22. By the suction force through the outflow port 212, the object to be collected can be sucked and collected by using the pipe connected to the inflow port 221.
A peephole 222 may be provided on the container lid portion 22. The peep window 222 is, for example, a transparent window made of glass or resin provided in a part of the container lid portion 22. By providing such a peephole 222, the amount of the object to be collected filled in the bag 3 can be visually confirmed without removing the container lid 22 from the container main body 21. When it was visually confirmed that the bag 3 was filled with the object to be collected, the suction / collection work was temporarily suspended, the container lid 22 was removed from the container body 21, and the object to be collected was filled. The bag body 3 and the new bag body 3 can be replaced.

An air wiper 223 may be provided in the vicinity of the peep window 222. The air wiper 223 includes a pipe 223a extending from the front surface of the container lid 22 to the back surface of the peephole 222, an on-off valve 223b and a cock 223c provided on the pipe (see FIGS. 7 (a) to 7 (c)). .. The usage of this air wiper 223 is as follows. For example, when the inner surface of the peephole 222 becomes dirty with a collection object, for example, a splash of sludge, 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 portion 2 with a force corresponding to the depressurizing pressure applied to the hard container portion 2 through the pipe 223a. At this time, the air that has entered the hard container portion 2 vigorously passes through the inner surface of the peephole 222, thereby removing the droplets of sludge adhering to the inner surface of the peephole 222. With such an air wiper 223, even if the inside of the peephole 222 becomes dirty with a collection object, the peephole 222 can be cleaned without removing the container lid 22 from the container main body 21, and the suction / collection work is interrupted. You can continue without any problems.

A pressure gauge 224 may be provided on the container lid portion 22. Even when a decompression 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 on the container lid portion 22, when a decompression load exceeding the durability of the hard container portion 2 is applied, the load can be rapidly removed by opening the relief valve 225.
Further, when the container body portion 21 and the container lid portion 22 are fastened by the fixing means 23, for example, the bolt 232 and the nut 231, it is preferable to make a screw hole 226 in the container lid portion 22, for example.
In addition, in order to proceed with the pipe connection work more smoothly, the inflow port pipe 227 may be provided in advance at the inflow port 221 (see FIG. 7 (d)). The inflow pipe 227 can be subjected to any conventionally used processing such as thread cutting 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 the packing 24 made of an elastic material is provided on the contact surface between the container body 21 and the container lid 22 (see FIG. 8). Examples of the elastic material include natural rubber, synthetic rubber and the like. The packing 24 may be provided only on the container main body 21 side, only on the container lid 22 side, or on both the container main body 21 side and the container lid 22 side.

The bag body 3 has an opening for receiving a collection object sucked through the inflow port 221. The size of the opening can be appropriately changed based on the size of the hard container portion 2, the type of the object to be collected, and the like. In the present invention, the "mesh" means a hole through which a liquid such as air or water and fine particles can pass through a sheet such as cloth. Therefore, the "mesh" in the present invention includes not only the mesh formed when threads, cloth, shredded resin sheets and the like are knitted, but also the gaps between the fibers entwined in the non-woven fabric. The mesh size can be appropriately changed based on the type of the object to be collected, the size of the grains contained in the object to be collected, and the like.
The mesh does not have 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 object to be collected is sucked and collected from the inlet 221 via the outlet 212 and is housed in the bag 3. Further, when sucking and collecting a mixture of a solid and a liquid, for example, sludge, the solid and the liquid (in some cases, a mixture of fine particles and the liquid that have passed through the mesh) are used through the bag 3. Is separated. Therefore, it is preferable that the mesh applied to the bag body 3 is applied to a wide range as much as possible, preferably the entire bag body 3. By applying a mesh over the entire bag body 3, a larger amount of objects to be collected while continuing to separate the solid and the liquid (in some cases, a mixture of fine particles and the liquid that have slipped 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 contained collection object. Examples of these materials include not only natural materials such as cotton and linen, but also synthetic resin materials such as polypropylene and polyethylene.

Further, the bag body 3 is preferably flexible. Since the bag body 3 is flexible, it can be stored compactly before using the bag body 3. Further, since the bag body 3 is flexible, it can be handled more easily when the bag body 3 after being filled with the collection target is transported or the like. Further, by using the flexible bag body 3 and the container main body 21 provided with the protrusion 217 in combination, the gap 218 can be created more easily, so that the efficiency of the suction / collection work can be further improved.
