  By the way, in such a cleaning body separation apparatus, since scale adheres to the filter separation member and the scale adheres to the filter separation member, the flow resistance of the fluid increases, and therefore the scale is removed from the filter separation member. Cleaning work needs to be done.

However, conventionally, it is difficult to clean the filter separation member because it is necessary to release the flange connection between the cylindrical main body and the main pipe and remove the cylindrical main body from the fluid flow path. Improvement was desired.
In addition, since the weight of the cylindrical body is heavy, the burden on the operator when removing and installing the cylindrical body from the fluid flow path becomes heavy, and depending on the weight of the cylindrical body, it is necessary to use a hoist Therefore, it is difficult to clean the filter separation member.

  This invention is made | formed in view of this situation, The objective is to provide the washing body separation apparatus which can facilitate the cleaning operation | work of a filter separation member.

The cleaning body separation device of the present invention includes a cylindrical main body provided on the downstream side of the installation location of the cleaning target portion in the fluid flow path through which the fluid flows, and the cylindrical main body assembled in the cylindrical main body. And a filter separation member for separating the cleaning body from the fluid flowing into
The cylindrical body has an opening for introducing the cleaning body filtered by the filtering member to the branch path, and the cleaning body that flows along with the fluid in the fluid flow path is separated into the branch path. Configured to:
Before SL tubular body, removably a insertion and removal opening of the filtration member is provided is positioned between the pair of connecting portions for connection to the fluid flow path,
Said filtration member, said at removably state through insertion and removal opening, the cylindrical body assembling et al is,
The filtering member includes a filtering part for filtering the cleaning body by allowing the fluid to pass through a part of the circumferential direction over the entire length in the longitudinal direction or substantially the entire length, and other than the filtering part in the circumferential direction. In the range of the full length in the longitudinal direction or a substantially cylindrical shape including a passage blocking portion that blocks the passage of the fluid in a state over the entire length,
The cylindrical main body is provided in the fluid flow path in a posture in which the pair of connection portions are arranged in a lateral direction above the insertion / removal opening, and the insertion / removal opening is connected to the introduction portion. As described above, the filtering member can be assembled in an inserted state in which the filtering part is in an obliquely downward posture and the filtering part is on the upper side as the connecting part on the fluid outlet side of the pair of connecting parts. In the state in which the filter separation member is configured, the fluid that has flowed in from the opening on the inlet side corresponding to the connection portion on the inlet side of the fluid of the pair of connection portions is the filter separation member. A flow path portion that guides to the opening at the end on the insertion side, and the fluid in the filtration member passing through the filtration portion toward the opening on the outlet side corresponding to the connection portion on the outlet side. And a flow path portion for guiding,
The right cylindrical filter separation member includes a pair of annular bodies that are concentrically located at intervals in the longitudinal direction, and a plurality of lengths that are arranged at intervals in the circumferential direction in a part of the circumferential direction. Connected by a scale-like body, the remaining portion in the circumferential direction is configured by connecting the cross-sectional shape by an arc-shaped plate-like body,
The filtration part is constituted by the part in which the plurality of elongated bodies in the straight cylindrical filtration member are arranged side by side, and the plate-like body in the straight cylindrical filtration member is provided. The passage blocking portion is constituted by the portion that is formed .

That is, in a state where the cylindrical body is connected to the fluid flow path by a pair of connecting portions, the filtering member is inserted and assembled into the cylindrical body through the insertion / removal opening, or the filtering member is inserted through the insertion / removal opening. It becomes possible to take out from the cylindrical main body.
That is, when the separation member is cleaned, it is possible to insert and remove only the separation member through the insertion / removal opening with the cylindrical main body connected to the fluid flow path.
Since the weight of the filter separation member is considerably lighter than that of the cylindrical main body, only the filter separation member is inserted / removed with the cylindrical main body connected to the fluid flow path when cleaning the filter separation member. By inserting and removing through the opening, it is possible to reduce the handling weight considerably compared to the case of attaching and detaching the cylindrical main body with the filter separating member assembled. Of course, the burden on the operator can be reduced.
Accordingly, it is possible to provide a cleaning body separation device that can facilitate the cleaning work of the filter separation member.

Further , the cylindrical main body is provided in the fluid flow path in such a posture that the pair of connection portions are arranged in the lateral direction above the insertion / removal opening, and the insertion / removal opening is used as the introduction portion to form a right cylindrical shape. The filter separation member is inserted into the cylindrical main body through the insertion / removal opening, and the filter separation part is in an obliquely downward posture and is positioned downward toward the connection part on the fluid outlet side of the pair of connection parts. Assemble into the cylindrical main body with the insertion side facing up.
Then, in such a state that the filtering member is assembled in the cylindrical main body, the fluid that has flowed into the cylindrical main body from the opening on the inlet side is guided to the opening on the insertion-side end of the filtering member. A flow path portion and a flow path portion that guides the fluid in the filter separation member through the filtration portion toward the opening on the outlet side are provided.

  Then, the fluid that flows together with the cleaning body from the fluid flow path into the cylindrical main body through the opening on the inlet side flows through the flow path portion from the opening on the inlet side to the opening on the insertion side end of the filtering member. Then, it flows into the filter separation member from the opening at the end on the insertion side, and a part of the inflowed fluid flows through the filter separation member and is introduced together with the cleaning body filtered by the filter separation member. It flows into the branch path through the part, and the remaining part flows through the flow path part that passes through the filtering part of the filtering member and reaches the opening on the outlet side, and flows into the fluid flow path.

Then, by assembling the filter separation member into the cylindrical main body in an obliquely downward posture with the filter separation part on the upper side and the passage blocking part on the lower side, the cleaning body can be pressed against the filtration part. It is possible to circulate along the inner peripheral surface of the passage blocking part and suppress the catching of the cleaning body on the filter separation member, and to filter well. It becomes.
By the way, if the filtering member is provided with a filtering part over its entire circumference, the cleaning body will move inside the filtering part as the fluid passes through the lower filtering part and flows out of the filtering member. Since it is pressed against the peripheral portion, the cleaning body is easily caught on the filter separation member.
Accordingly, the cleaning body can be further suppressed from being caught by the filter separation member, and the cleaning body can be further separated by filtration.

Further , the separation part of the separation member is constituted by a plurality of long bodies arranged at intervals in the circumferential direction of the separation member, so that the separation part can be divided into a plurality of slits in the longitudinal direction. Along the flow direction of the filter and arranged in the circumferential direction in a state covering the full length or substantially the full length of the filter separation member.
As a result, there is no edge that intersects the flow direction of the fluid on the inner peripheral side of the filtering portion, or even if it exists, it is possible to reduce as much as possible. Can be further suppressed from being caught by the filtered portion.
By the way, if the filter separation part is configured to be present in the direction of fluid flow intermittently, there will be many edges that intersect the fluid flow direction on the inner peripheral side of the filter separation part, The cleaning body is easily caught on the edge.

  Further, in constructing a right cylindrical filter separation member having a filtering part in a part in the circumferential direction and a passage blocking part in a range other than the filtering part in the circumferential direction, as described above, A pair of annular bodies positioned concentrically at intervals are connected by a plurality of elongated bodies arranged at intervals in the circumferential direction in a part of the circumferential direction, and in the remaining portion in the circumferential direction Compared to the case where the plate-shaped material in which slits are formed by pressing or the like is formed into a cylindrical shape by connecting and configuring it with a plate-like body having an arc-shaped cross-section, the filtered portion It is possible to increase the strength and improve the durability.

In addition, the slit is formed by arranging a plurality of elongated bodies side by side at intervals, so that the elongated body has a strong cross-sectional shape such as a square or a circular rod. Since it can be used, the strength of the filtered portion can be sufficiently increased.
On the other hand, when the slit is formed by pressing a plate-shaped material, it is difficult to increase the thickness of the plate-shaped material, so that it is difficult to increase the strength of the filtered portion.
Accordingly, it has become possible to more satisfactorily filter the cleaning body while improving durability.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, the cleaning device 100 including the cleaning body sorting device 30 will be described.
As shown in FIG. 1, the cleaning device 100 is a heat as a cleaning target portion provided in a fluid flow path 1 through which a fluid F such as cooling water flows, such as an absorber or condenser of an absorption chiller / heater. Sponge-like cleaning balls SB made of rubber, resin or the like as a cleaning body are circulated in the heat transfer tube 22 of the exchanger 20 together with the fluid F to be generated in the heat transfer tube 22 of the heat exchanger 20. Configured to remove the scale.

Such a cleaning apparatus 100 is a cleaning ball that flows along with the fluid F to the downstream branch path 3 that branches from the downstream side 1B to the downstream side 1B of the heat exchanger 20 provided in the fluid flow path 1 through which the fluid F flows. The cleaning body sorting device 30 for sorting SB is provided.

The separating part filtering member 32 is provided in the cylindrical body 31. An inlet 31h as an introducing portion for introducing the washed ball SB separated by filtration to the downstream branch passage 3 as a branch passage is opened, and the cleaning ball SB flowing along with the fluid F in the fluid passage 1 is passed through the downstream branch passage. It is comprised so that it may classify into 3.

  Furthermore, the cleaning apparatus 100 includes a circulation path 4 that connects the downstream branch path 3 and the upstream branch path 2 that branches from the upstream side 1A of the heat exchanger 20 in the fluid flow path 1, and the upstream branch path. 2 includes a pump 9 capable of transporting the fluid F in a direction from the downstream branching path 3 toward the upstream branching path 2.

  Further, the cleaning apparatus 100 includes an upstream collection and delivery path 6 that branches from the connection portion between the circulation path 4 and the upstream branch path 2, and a downstream collection that branches from the connection section between the circulation path 4 and the downstream branch path 3. A delivery path 7, and further arranged between the upstream collection delivery path 6 and the downstream collection delivery path 7 in a form of partitioning the upstream collection delivery path 6 and the downstream collection delivery path 7. A cleaning body storage section 40 including a storage section filtering member 43 for filtering the cleaning balls SB from F is provided.

The cleaning body container 40 is formed in such a manner that the upper side and the lower side are partitioned in a sealed container 41 in which the downstream side collection and delivery path 7 is connected to the upper side part and the upstream side collection and delivery path 6 is connected to the lower bottom part. An accommodating portion filtering member 43 is provided. In addition, the accommodating portion filtering member 43 is constituted by a porous plate material or a net provided with many holes having a diameter smaller than the diameter of the cleaning ball SB.
That is, when the fluid F circulates in the sealed container 41 from the downstream collection / delivery path 7 side toward the upstream collection / delivery path 6 side, the cleaning body accommodating portion 40 circulates along with the fluid F. In the case where SB is separated and collected by the container filtering member 43 and conversely, the fluid F flows through the sealed container 41 from the upstream collection delivery path 6 side toward the downstream collection delivery path 7 side, The cleaning ball SB on the container filtering member 43 is configured to be sent to the downstream collection and delivery path 7 side together with the flow of the fluid F.

  Further, the cleaning apparatus 100 is configured to connect the downstream branch path 3 and the upstream branch path 2 to the circulation state connected via the circulation path 4 and the collection and delivery connected via the cleaning body container 40. As a switching means capable of switching to a state, a three-way switching valve 10 connected to the circulation path 4, the downstream branch path 3, and the downstream collection delivery path 7 is provided.

  That is, as shown in FIG. 4, the three-way switching valve 10 makes the port 10a connected to the circulation path 4 and the port 10b connected to the downstream branch path 3 communicate with each other, and the downstream collection and delivery path. By closing the port 10c to which the terminal 7 is connected, the downstream branch path 3 and the upstream branch path 2 are connected to each other via the circulation path 4, while FIG. 2, FIG. 3 and FIG. As shown in FIG. 4, the port 10b and the port 10c are brought into a communication state and the port 10a is brought into a closed state, whereby the downstream branch passage 3 and the upstream branch passage 2 are connected to the cleaning body containing portion 40. It is possible to establish a collection / delivery state connected through the network.

Further, the cleaning device 100 includes an operation control device 50 that controls the operation of the pump 9 and the three-way switching valve 10.
Hereinafter, the control operation of the operation control device 50 will be described.

  As shown in FIG. 4, the operation control device 50 operates the pump 9 and sets the three-way switching valve 10 in the circulating state (the ports 10a and 10b are in communication with each other and the port 10c is in the closed state). In this state, the cleaning ball SB is circulated between the heat transfer tube 22 of the heat exchanger 20 and the circulation path 4 together with the fluid F to clean the heat transfer tube 22 of the heat exchanger 20. It is configured to perform a circulating operation.

  Accordingly, the cleaning ball SB during the cleaning body circulation operation passes through the circulation path 4 without passing through the cleaning body storage unit 40, and thus the cleaning body storage unit 40 of the cleaning ball SB. Wear due to a collision with the inner wall of the closed container 41 or the container separation member 43 is prevented.

  Further, after executing the cleaning body circulation operation, the operation control device 50 causes the three-way switching valve 10 to communicate with the collection and delivery state (port 10b and port 10c in a state where the pump 9 is operated as shown in FIG. In this state, the cleaning body recovery operation is performed to set the port 10a in a closed state.

That is, when the cleaning body recovery operation is executed by the operation control device 50, the fluid F flowing into the downstream branch passage 3 together with the cleaning ball SB is directed from the downstream recovery delivery path 7 side toward the upstream recovery delivery path 6 side. The inside of the sealed container 41 is distributed.
Therefore, by executing the cleaning body recovery operation, the cleaning ball SB can be recovered on the storage portion filtering member 43 of the cleaning body storage portion 40.

  The time for performing the cleaning body recovery operation by the operation control device 50 is set as a time during which the cleaning ball SB can be completely recovered on the container filtering member 43, and such time can be obtained by experiment, calculation, or the like. it can.

  Further, the operation control device 50, as shown in FIG. 2 and FIG. 3, performs the three-way switching valve 10 in the recovery / delivery state (port 10b and port 10c) without operating the pump 9, as shown in FIGS. Is in a communicating state and the port 10a is in a closed state).

  That is, when the cleaning body delivery operation is executed by the operation control device 50, the fluid pressure in the upstream branch 2 is higher than the fluid pressure in the downstream branch 3, so that the fluid on the upstream side 1A of the heat exchanger 20 is higher. F flows into the cleaning body container 40 via the upstream branch path 2 and the upstream collection / delivery path 6, and the fluid F flows from the cleaning body container 40 into the downstream collection / delivery path 7. It will distribute | circulate to the downstream branch 3 via this.

  Therefore, by executing the cleaning body delivery operation, the cleaning ball SB on the storage portion filtering member 43 of the cleaning body storage portion 40 is placed on the flow of the fluid F as shown in FIG. It can be sent to the collection delivery path 7 and the downstream branch path 3 and can stay in the downstream branch path 3 as shown in FIG.

  The time for performing the cleaning body delivery operation by the operation control device 50 is set as the time during which the cleaning ball SB can be completely delivered into the downstream branching path 3, and such time can be obtained by experiments, calculations, and the like. .

  The operation control device 50 is configured to sequentially execute the cleaning body delivery operation, the cleaning body circulation operation, and the cleaning body recovery operation over a predetermined time for each predetermined period. Has been.
