  In the solid separation device of the present invention, it is preferable that the sieve member is a rail in which tracks are arranged at intervals of the predetermined diameter or less.

  In the solid separation device of the present invention, it is also preferable that the sieve member is a net-like body having an opening having a predetermined diameter or less.

  In the solid separation device of the present invention, the recovery container includes a rotary blade mechanism having a plurality of blade bodies centering on the rotation axis, the end of which is in airtight contact with the inner wall of the recovery container.

--- Configuration of solid-state separator ---
Embodiments of the present invention will be described below in detail with reference to the drawings. In the present embodiment, for example, a situation where a solid test with a wireless IC tag is drained together with water (fluid) using a drain pipe in a building such as a commercial building or a condominium, as a flow path, and a water passage test is performed. Suppose. Therefore, it is necessary to separate and collect the solid material attached with the wireless IC tag from the water at an appropriate collection position. The solid separation device of the present invention will be used to collect the solid object attached with the wireless IC tag. Of course, the application target of the present invention is not limited to the above, and the present invention can be applied to various situations in which a solid material is separated from a fluid containing the solid material.

  FIG. 1 is a diagram showing a structural example 1 of the solid separation device in the present embodiment. The solid separation device 100 is configured to collect the test body 10 (attached to the wireless IC chip 20), which is a solid material flowing down from the upstream side 41 of the drainage pipe 40, at the downstream side 42 of the drainage pipe 40. A suction tube 101 directed toward the fluid 5 is provided at a predetermined position on the side 42. As described above, one end of the suction pipe 101 is the opening 111 directed to the fluid 5, and the other end 112 is connected to a predetermined suction machine 50 such as a vacuum cleaner.

  The suction machine 50 includes a negative pressure generating device such as a pump, and can apply a negative pressure to the inside of the suction pipe 101. By operating this suction machine 50 and generating a negative pressure in the pipe of the suction pipe 101, the fluid 5 is drawn into the pipe from the opening 111 of the suction pipe 101 toward the suction machine 50.

  Since the drawing of the fluid 5 from the suction pipe 101 is continued while the suction machine 50 is operating, the flow toward the suction machine 50 from the downstream side 42 of the drainage pipe 40 through the suction pipe 101 is performed. A path 30 is formed. The solid separation device 100 includes a branch pipe 103 that branches in the centrifugal direction 31 from the flow path 30 in the suction pipe 101 at a predetermined branch point 102 of the suction pipe 101. As a result, a conduit for guiding the flow path 32 branched from the flow path 30 is formed. The flow path 32 is a flow path from the suction pipe 101 to the branch pipe 103 and has an arc shape extending in a direction gradually separating from the flow path 30.

  Therefore, the solid separation device 100 includes a sieving member 104 on the centrifugal side 33 of the arc shape in the suction pipe 101 and the branch pipe 103 in accordance with the arc shape of the flow path 32. The sieving member 104 has a structure for sieving a solid object 10 having a predetermined diameter or more. In the example of FIG. 1, for example, a rail 115 in which tracks 114 are arranged at intervals of the predetermined diameter or less is assumed. it can.

  In this case, the fluid 5 (attached to the solid material 10) flowing from the suction pipe 101 due to the flow of the flow path 30 directly hits the rail 115 provided around the branch point 102. . The solid object 10 is trapped between the tracks 114 of the rail 115 and is moved by the flow of the flow path 30 to move on the rail 115 from the branch point 102 toward the branch pipe 103. The movement of the solid object 10 along the rail 115 becomes the flow path 32 as it is, and flows in a direction gradually separating from the flow path 30 according to the arc shape.

  The sieve member 104 may be a net-like body 129 having an opening 128 having a predetermined diameter or less as shown in FIG. In this case, the fluid 5 (attached to the solid material 10) flowing from the suction pipe 101 due to the flow of the flow path 30 is directly applied to the mesh body 129 provided around the branch point 102. Clash. The solid object 10 is trapped in the opening 128 of the mesh 129 and is moved by the flow of the flow path 30 to move on the mesh 129 from the branch location 102 toward the branch tube 103. The movement of the solid object 10 along the mesh 129 becomes the flow path 32 as it is, and the flow in a direction gradually separating from the flow path 30 according to the arc shape.

  Further, when the fluid 5 containing the solid object 10 is sucked from the suction pipe 101 to the branch pipe 103, the solid object 10 loses momentum of movement due to the resistance of the fluid 5, and the fluid 5 and the solid object 10 Considering that the pipe diameter of the branch pipe 103 and the suction pipe 101 at the branch point 102, which is a region where the rail 115 of the track 114 starts to be curved, is not too large relative to the diameter of the solid object 10 so that the separation is not performed. Is preferred. For example, the difference between the inner diameter of the branch pipe 103 and the diameter of the solid object 10 at the branch point 102 may be within a few mm (eg, about 3 mm).

  On the other hand, the fluid 5 from which the solid object 10 is separated as it hits the rail 115 is drawn from the suction pipe 101 toward the suction machine 50. At this time, if the suction device 50 is a vacuum cleaner having a drainage function, the fluid 5 may be sucked as it is and discharged through the cleaner. Further, when the suction device 50 does not have a drainage function, an appropriate gas-liquid separation device 151 may be disposed between the suction tube 101 and the suction device 50 to cope with it.

  The solid separation device 100 is connected to the rear end 105 of the branch pipe 103 in an airtight manner, and stores a solid material 10 that is guided from the suction pipe 101 through the sieve member 104 to the branch pipe 103. 106 is provided. The recovery container 106 needs to continuously recover the solid material 10 guided through the branch pipe 103 along the rail 115.

  Thus, a mechanism for discharging the solid object 10 that is preferably provided in the recovery container 106 will be described. In the present embodiment, for example, the collection container 106 includes a rotary blade mechanism 116. The rotary blade mechanism 116 is a mechanism including a plurality of blade bodies 119 whose end portions 117 are in airtight contact with the inner wall 118 of the collection container, with the rotary shaft 120 as a center.

  The rotary blade mechanism 116 rotates the blade body 119 by driving the rotary shaft 120 with a driving means such as a motor. The solid material 10 accommodated in the recovery container 106 via the branch pipe 103 is introduced by dropping into the transfer area 121 between the blade bodies 119 and is gradually moved to the discharge port 122 by the rotation of the blade bodies 119. To do. At this time, since the end portion 117 of the blade body 119 is in airtight contact with the inner wall 118 of the collection container, the airtightness between the inside of the collection container and the discharge port 122 is maintained. When the transport area 121 reaches the discharge port 122, the solid material 10 introduced into the transport area 121 is discharged from the discharge port 122.

  In addition, as a mechanism for discharging the solid object 10 provided in the recovery container 106, another mechanism as shown in FIG. 3 can be assumed. FIG. 3 is a diagram showing a structural example 2 of the recovery container in the solid separation device of the present embodiment. Here, for example, the collection container 106 includes a wind vent chamber mechanism 123. The wind venting mechanism 123 is a mechanism in which the airtight doors 124 are arranged in multiple in the collection container. The solid object 10 accommodated in the recovery container 106 through the branch pipe 103 is introduced by dropping into the front door 125 of the airtight door 124 which is disposed at a position closest to the branch pipe 103. At this time, at least the hermetic door 124 is closed.

  The wind removal chamber 123 closes the hermetic door 126 adjacent to the hermetic door 124 and then opens the hermetic door 124, so that the solid object 10 is moved from the door front 125 of the hermetic door 124 to the airtight door 126. Move to door 127. Further, after a predetermined time has elapsed, the airtight door 124 is closed. Thus, confidentiality between the hermetic door 124 and the branch pipe 103 is maintained. By repeating such processing from the hermetic door 124 at the closest position of the branch pipe 103 to the hermetic door 126 at the closest position of the discharge port 122, the movement and discharge of the solid object 10 to the discharge port 122 can be executed.

--- About water flow test ---
As described above, the application state of the present invention will be described in the case where the solid object 10 is attached to the wireless IC tag 20 and a water passage test using the solid object 10 is assumed. In this case, the wireless IC tag 20 attached to the solid object 10 stores attribute information of the drainage pipe 40 through which drainage as the fluid 5 flows. At this time, the sieving member 104 in the solid separation device 100 of the present invention sifts the solid object 10 having a predetermined diameter or more attached to the wireless IC tag 20, and the recovery container 106 removes the wireless IC tag 20. The accompanying solid object 10 is stored. The attribute information stored in the wireless IC tag 20 includes, for example, an input point and an ID of the carrying person of the charging person (an ID for identifying each part on the upstream side 41 of the drainage pipe and the processing terminal in charge), charging time information, goal ID (the downstream side 42 of the drainage pipe 40, that is, the ID for each target point that the solid object 10 as the test body should reach), and the like are included.

  Note that the test body that is the solid object 10 may take the form of a sphere, a polyhedron, or the like. However, the branch pipe 103 is directed toward the collection container 106 along the sieve member 104 according to the flow of the fluid 5. It is not limited to these as long as it is movable. Moreover, the test body which is the solid object 10 may be provided with an opening that allows inflow of water in order to flow down integrally with the fluid 5 flowing in the flow path during the water flow test. Alternatively, the solid material 10 itself may be water-absorbing or clay-like.

  As a specific test body, a plastic golf ball, a soft tennis ball, a rubber ball, or the like can be used. For example, in the case of a plastic golf ball, for example, a 13.56 MHz band label-like wireless IC tag is rolled and inserted into the inside. Since such a test body is separated from the fluid 5 by the solid separation device 100 of the present invention, it is freed from the conventional problem that the wireless IC tag 20 is surrounded by water and cannot read the tag. Therefore, efficient and reliable tag reading is possible.

  When the test body is a rubber ball or a soft tennis ball, a hole is made in the ball so that a fluid such as water can enter inside, and for example, a non-conductor of about 1 mm on both sides of the 13.56 MHz band antenna. A wireless IC tag provided with a layer may be inserted. As a result, communication with the reader / writer is possible even if the wireless IC tag 20 is encased in moisture.

  The test body is read by a reader / writer device or the like on the downstream side 42 of the drain pipe 40. The storage point of the wireless IC tag 20 included in the test body obtained in this way and the ID of the carrying terminal of the charging person (ID for identifying each place on the upstream side 41 of the drainage pipe and the processing terminal in charge), The input time information and the goal ID (downstream side 42 of the drainage pipe 40, that is, the ID for each target point to which the solid object 10 should reach) are the downstream side 42 of the drainage pipe 40 that the test specimen has actually reached. It is used for processing such as determining the legitimacy of the route by collating with an ID (corresponding to the goal ID) and calculating the drainage time based on the input time and the collection time. In this way, the water flow test is executed.

  According to the present invention, for example, a solid substance contained in a fluid can be separated and recovered while continuously operating a suction device such as a vacuum cleaner, and the separation of the fluid and the solid can be realized quickly and efficiently. Further, by providing the recovery container of the solid separation device with a rotating blade mechanism and a wind vent chamber mechanism, the discharge port of the solid object and the inside of the recovery container can be airtightly partitioned when the solid object is discharged from the recovery container. . Accordingly, it is possible to discharge the solid matter out of the solid separator while continuously operating the vacuum cleaner and continuing the suction of the fluid. Therefore, it is possible to quickly and efficiently recover the target solid matter regardless of the capacity of the recovery container.

  In particular, if the present invention is applied in a situation where a test body (solid material) attached with a wireless IC tag is used for a drainage test, water and the test body can be separated quickly and continuously, and the surrounding environment is water. The problem that the reading accuracy of the wireless IC tag is lowered can be solved. In addition, the wireless IC tag can be automatically read at the collection point of the test body without requiring a manual operation, and the efficiency of the inspection work in the drainage water flow test can be realized.

  Accordingly, the solid material and the liquid can be separated from each other while the suction of the fluid containing the solid material is continuously performed.

  As mentioned above, although embodiment of this invention was described concretely based on the embodiment, it is not limited to this and can be variously changed in the range which does not deviate from the summary.
