Description

  The present invention relates to a filter cleaning apparatus and a filter cleaning method for removing dirt adhered to a filter by spraying a cleaning liquid.

  2. Description of the Related Art Conventionally, a filter cleaning device that cleans a filter by spraying high-pressure water and high-pressure gas from above the filter while moving the filter on a conveyor is known. Injection of high-pressure water and high-pressure gas is performed from injection nozzles that are provided in a cylindrical duct extending in the width direction of the conveyor and are installed at equal intervals in the length direction of the duct (for example, Patent Documents). 1).

  However, it is used to increase the foreign matter collection rate of the filter, and the spray nozzle shown in Patent Document 1 is suitable for cleaning a filter in which the filter medium is folded in a pleat shape and arranged in a V shape. It wasn't. This is because, when the filter medium is folded into a pleat shape and further arranged in a V shape, there is a portion where the cleaning liquid does not hit the pleated valley of the filter medium when the cleaning liquid is sprayed from above. .

  In order to solve the above problems, the injection nozzle is a circular pipe-shaped rod (pipe) having a certain length and a diameter of several millimeters, and pores are provided in the tip of the pipe and the side surface of the tip of the pipe. It has been conventionally known to use a circular tube nozzle. By inserting such a circular tube-shaped nozzle into the valley of the filter disposed in the V shape, it is devised so that the cleaning liquid also hits the pleated valley of the filter medium (see, for example, Patent Document 2).

However, the prior art has the following problems.
In the filter cleaning device disclosed in Patent Document 2, the tip of a pipe inserted into the valley of the filter is thin. For this reason, there exists a possibility that a filter medium may be damaged because the front-end | tip of a pipe contacts a filter. As a result, the foreign matter collecting ability of the filter is reduced. Further, in the circular tube-shaped nozzle, the pore is provided only at the tip portion of the pipe. For this reason, the spray area of the cleaning liquid is small, and it takes time to clean the entire filter.

  Furthermore, when the cleaning liquid is circulated and used, foreign matter accumulates in the pores of the pipe and the cleaning liquid does not come out. Here, the diameter of the pipe is as small as several millimeters, and it is difficult to clean the accumulated matter inside the pipe. Therefore, when the cleaning liquid is not discharged, the pipe is disposable and the economy is deteriorated. On the other hand, it is possible to clean the pipe by detaching the tip of the pipe, but it requires precision machining, leading to an increase in cost.

  The present invention has been made to solve the above-described problems, and is capable of preventing the filter medium from being damaged, reducing the cleaning time, and easily cleaning the inside of the nozzle, and An object is to obtain a filter cleaning method.

The cleaning zone 5 is covered by a waterproof outer frame 6 for preventing the cleaning liquid and the cleaning water supplied from the cleaning liquid supply device 12 and the cleaning water supply device 13 and sprayed from the cleaning liquid injection unit 14 from being scattered around. It has been broken.

  The conveyance device 11 includes a plurality of conveyance rollers 111. The transport roller 111 is a cylinder having a rotation axis. Further, the transport rollers 111 are arranged in the horizontal direction with their longitudinal directions being adjacent to each other and spaced apart from each other. Each transport roller 111 is rotated in the same direction by a roller drive motor (not shown).

  The V-type filter 1 placed on the transport roller 111 is transferred from the entrance of the cleaning zone 5 to the exit of the cleaning zone 5 by the rotation of the transport roller 111. The transfer direction of the V-type filter 1 is the direction of the arrow D in FIG. The V-type filter 1 is placed on the conveyance roller 111 so that the bellows folding direction of the filter medium 2 of the V-type filter 1 and the transport direction of the V-type filter 1 coincide. Thereby, the direction of the valley fold line of the V-type filter 1 (the valley part of the V-type filter 1) coincides with the vertical direction (the vertical direction of the cleaning device 10 shown in FIG. 2).

  The cleaning liquid supply device 12 is provided on the inlet side of the cleaning zone 5. The cleaning liquid supply device 12 includes a cleaning liquid storage tank 121, a cleaning liquid pump 122, a cleaning liquid feeding pipe 123, a cleaning liquid supply pipe 124, and a cleaning liquid receiving container 125.

The cleaning liquid storage tank 121 is a container having a substantially rectangular cross section that is disposed below the transport roller 111 and is open at the top. In this example, the cleaning liquid collected by the cleaning liquid receiving container 125 is circulated to the cleaning liquid storage tank 121 and reused.

  The cleaning liquid pump 122 is connected to the cleaning liquid storage tank 121. The cleaning liquid pump 122 includes a pump drive motor (not shown). The cleaning liquid pump 122 sucks up the cleaning liquid from the cleaning liquid storage tank 121 by the driving force of the pump drive motor. The sucked cleaning liquid is sent to a cleaning liquid feed pipe 123 connected to the cleaning liquid pump 122. The timing at which the cleaning liquid pump 122 starts sucking up the cleaning liquid is when the V-type filter 1 transferred by the transport roller 111 reaches the set cleaning position. The set cleaning position is determined by the position of the valley of the V-type filter 1.

  The cleaning liquid feed pipe 123 is a passage for the cleaning liquid sent from the cleaning liquid pump 122. The cleaning liquid feeding pipe 123 carries the cleaning liquid from below the transport roller 111 to above the transport roller 111. The cleaning liquid feeding pipe 123 is branched into a plurality (two in this example), one is directed to the surface of the cleaning surface of the V-type filter 1 and the other is directed to the back surface of the cleaning surface of the V-type filter 1. The cleaning liquid feeding pipe 123 sends the cleaning liquid to the cleaning liquid supply pipe 124 installed above the transport roller 111.

  The cleaning liquid supply pipe 124 is connected to each of the cleaning liquid supply pipes 123. Therefore, in this example, two cleaning liquid supply pipes 124 are provided. The cleaning liquid supply pipe 124 is a pipe that supplies the cleaning liquid to the cleaning liquid injection unit 14.

  FIG. 4 is an enlarged view showing the cleaning liquid ejecting section 14 of FIGS. 2 and 3. The cleaning liquid injection unit 14 includes an injection pipe 142 having a plurality of holes (injection holes) 141 for injecting the cleaning liquid, a cleaning liquid supply pipe 124 (not shown in FIG. 4), and an injection pipe 142. And a connection housing 143 to be connected. Further, the cleaning liquid ejecting section 14 is connected to each of the cleaning liquid supply pipes 124, and two cleaning liquid injection sections 14 are used in this example.

  The connection housing 143 has a box part 143a, a pipe connection port 143b, and a pipe connection port 143c. As the box part 143a, a box having a substantially rectangular cross section is used. The longitudinal direction of the box portion 143a is directed along the vertical direction of the cleaning device 10.

  The pipe connection port 143 b is provided on a surface (filter facing surface) where the box portion 143 a faces the V-type filter 1 placed on the transport roller 111 and is connected to the injection pipe 142. A plurality of pipe connection ports 143b are provided at a distance from each other along the longitudinal direction of the box portion 143a.

  The pipe connection port 143c is provided on the surface of the box part 143a facing the filter facing surface and is connected to the cleaning liquid supply pipe 124. In this example, one pipe connection port 143c is provided and four pipe connection ports 143b are provided. The cleaning liquid sent from the cleaning liquid supply pipe 124 flows into the box portion 143a through the pipe connection port 143c, and then flows into each pipe connection port 143b.

  The injection pipe 142 includes a first pipe 142a, a second pipe 142b provided away from the first pipe 142a, and a third pipe that connects ends of the first pipe 142a and the second pipe 142b. The pipe 142c. The first pipe 142a, the second pipe 142b, and the third pipe 142c are connected in a substantially U shape. In this example, the first pipe 142a, the second pipe 142b, and the third pipe 142c are manufactured integrally. The injection pipe 142 is a pipe having a diameter of several millimeters.

  The injection pipe 142 is detachably inserted into the pipe connection port 143b. Since the shape of the injection pipe 142 is substantially U-shaped, two pipe connection ports 143 b are necessary to insert one injection pipe 142 into the connection housing 143. The injection pipe 142 has an end portion where the first pipe 142a and the second pipe 142b are not connected to the third pipe 142c inserted into the pipe connection port 143b. That is, both U-shaped ends of the injection pipe 142 are attached to the connection housing 143. At this time, the longitudinal direction of the third pipe 142c is directed in the direction along the vertical direction of the cleaning device 10, and the third pipe 142c is disposed to face the cleaning surface of the V-type filter 1. As the pipe connection port 143b, for example, a pipe that can be connected by simply pushing in a pipe such as a one-touch joint can be used.

  Each passage is provided with a plurality of injection holes 141 for injecting the cleaning liquid. The injection holes 141 are spaced from each other at intervals. In addition, the injection hole 141 is formed so that the cleaning liquid can be injected in the left-right direction toward the cleaning surface of the V-type filter 1 when both U-shaped ends of the injection pipe 142 are attached to the connection housing 143. Yes. In this example, an injection hole 141 of the same size (size) is formed in the injection pipe 142. Although not visible in FIG. 4, the injection holes 141 are formed on both surfaces of the injection pipe 142. The injection hole 141 is a substantially circular hole. The cleaning liquid that has flowed into the pipe connection ports 143b from the box portion 143a is sprayed from the spray holes 141 while passing through the passages.

  FIG. 5 is a schematic diagram showing the direction in which the cleaning liquid flows into the injection pipe 142. As shown in FIG. 5, the cleaning liquid flowing into the box portion 143 a flows into the first pipe 142 a and the second pipe 142 b of the injection pipe 142. The cleaning liquid that has flowed into the first pipe 142a and the second pipe 142b proceeds to the third pipe 142c, respectively. Accordingly, the cleaning liquid flows into the third pipe 142c from both sides (the first pipe 142a side and the second pipe 142b side). The cleaning liquid that has flowed into each pipe is ejected from an ejection hole 141 provided in each pipe.

  FIG. 6 is a schematic diagram illustrating a state in which the cleaning liquid is sprayed from the cleaning liquid spray unit 14 to the V-type filter 1. As shown in FIG. 6, the cleaning liquid ejecting unit 14 ejects the cleaning liquid in a state of being inserted into the valley of the V-type filter 1. As a result, the cleaning liquid sprayed from the cleaning liquid spraying unit 14 strikes the filter medium 2 forming the valley of the V-type filter 1 at an angle close to vertical.

  In order to adjust the cleaning position at which the cleaning liquid ejecting section 14 cleans the V-type filter 1, the cleaning liquid supply pipe 124 connected to the cleaning liquid ejecting section 14 via the connection housing 143 is ejected as shown in FIG. Is connected to the unit moving device 15.

  The injection unit moving device 15 includes a first moving mechanism 151 that moves the cleaning liquid injection unit 14 so as to change the relative distance of the cleaning liquid injection unit 14 with respect to the same cleaning portion of the V-type filter 1, and different cleaning locations of the V-type filter 1 On the other hand, it has the 2nd moving mechanism 152 which moves the washing | cleaning-liquid injection part 14. FIG.

  The first moving mechanism 151 is provided on a support bar 153 provided in the cleaning zone 5. The upper part of the support bar 153 is provided in the second moving mechanism 152 installed on the upper part of the waterproof outer frame 6, and the lower part of the support bar 153 is fixed to the cleaning liquid receiving container 125. Thereby, the support bar 153 is installed along the vertical direction of the cleaning device 10. A ball screw or the like is used for the support bar 153. As shown in FIG. 3, the support rods 153 are respectively provided on the front surface side of the cleaning surface of the V-type filter 1 and on the back surface side of the cleaning surface of the V-type filter 1. The first moving mechanism 151 moves the cleaning liquid supply pipe 124 closer to or away from the cleaning surface of the V-type filter 1. The direction approaching or moving away from the cleaning surface is a direction along the longitudinal direction of the transport roller 111. Accordingly, the cleaning liquid ejecting unit 14 can be inserted into the valley portion of the V-type filter 1.

  The second moving mechanism 152 is provided in the upper part of the waterproof outer frame 6 and rotates each support rod 153. The second moving mechanism 152 moves the first moving mechanism 151 along the support bar 153 by rotating the support bar 153. Accordingly, the cleaning liquid ejecting unit 14 is moved in the vertical direction of the cleaning device 10 along the support bar 153 with respect to the cleaning surface of the V-type filter 1.

  FIG. 7 is an operation diagram illustrating a cleaning path of the cleaning liquid ejecting unit 14 in the valley portion of the V-type filter 1. As shown in FIG. 7, the cleaning liquid ejecting unit 14 is moved from the upper side to the lower side while drawing a rectangular wave shape from the trough portion of the V-type filter 1 at the upper part of the V-type filter 1 by the ejecting unit moving device 15. . Since the cleaning liquid injection unit 14 is moved from the top to the bottom with respect to the V-type filter 1 by the injection unit moving device 15, the foreign matter 4 separated by the cleaning liquid flows from the top to the bottom together with the used cleaning liquid.

  In this way, as shown in FIG. 2, the used cleaning liquid sprayed from the cleaning liquid ejecting unit 14 to the V-type filter 1 is disposed below the transport roller 111 at the cleaning position on which the V-type filter 1 is placed. Falls into the cleaning liquid receiving container 125.

  The cleaning liquid receiving container 125 is a container that receives the used cleaning liquid that falls. A foreign matter filtering filter (not shown) is provided in the cleaning liquid receiving container 125. The foreign matter filtering filter removes the desired foreign matter 4 from the used cleaning liquid. The used cleaning liquid from which certain foreign substances 4 have been removed by the foreign substance filtering filter falls into the cleaning liquid storage tank 121 disposed below the cleaning liquid receiving container 125. The desired foreign matter 4 varies depending on the coarseness of the foreign matter filter used.

  Next, the cleaning water injection performed following the cleaning liquid injection will be described with reference to FIG. FIG. 8 is a cross-sectional view showing the structure of the side surface of the filter cleaning device of FIG. 2 on the cleaning water supply device 13 side.

  The cleaning water supply device 13 is provided on the outlet side of the cleaning zone 5. The cleaning water supply device 13 includes a cleaning water drain tank 131, a cleaning water pump 132, a cleaning water feed pipe 133, a cleaning water supply pipe 134, a cleaning water receiving container 135, and a drain pipe 136.

  The cleaning water pump 132 is connected to the water pipe and supplies cleaning water. Like the cleaning liquid pump 122, the cleaning water pump 132 includes a pump drive motor (not shown). The washing water pump 132 sucks up the washing water by the driving force of the pump drive motor. The sucked cleaning water is sent to the cleaning water feed pipe 133 connected to the cleaning water pump 132. The timing at which the cleaning water pump 132 starts sucking the cleaning water is the same as the cleaning liquid pump 122 when the V-type filter 1 transferred by the transport roller 111 reaches the set cleaning position. Further, the set cleaning position is also determined by the position of the valley of the V-type filter 1, similarly to the cleaning liquid pump 122.

  The cleaning water feed pipe 133 is a passage for the cleaning water sent from the cleaning water pump 132. The cleaning water feed pipe 133 carries cleaning water from below the transport roller 111 to above the transport roller 111. As with the cleaning liquid feeding pipe 123, the washing water feeding pipe 133 branches into a plurality (two in this example), one facing the surface of the washing surface of the V-type filter 1, and the other washing the V-type filter 1. Head to the back of the face. The cleaning water supply pipe 133 sends the cleaning liquid to the cleaning water supply pipe 134 installed above the transport roller 111.

  The cleaning water supply pipe 134 is connected to each of the cleaning water feed pipes 133. Accordingly, in this example, two cleaning water supply pipes 134 are provided. In addition, the cleaning water supply pipe 134 is a pipe that supplies the cleaning liquid to the cleaning liquid injection unit 14, similarly to the cleaning liquid supply pipe 124.

  The cleaning liquid injection unit 14 is connected to each of the cleaning water supply pipes 134. Further, the cleaning liquid ejecting unit 14 uses the same thing in the cleaning liquid supply device 12 and the cleaning water supply device 13. Therefore, in this example, a total of four cleaning liquid ejecting units 14 are used. In addition, the ejection unit moving device 15 uses the same material for the cleaning liquid supply device 12 and the cleaning water supply device 13. The used cleaning water sprayed from the cleaning liquid ejecting unit 14 to the V-type filter 1 falls into the cleaning water receiving container 135 disposed below the transport roller 111 at the cleaning position on which the V-type filter 1 is placed.

  The cleaning water receiving container 135 is a container that receives the used cleaning water that falls. The cleaning water receiving container 135 drops the received used cleaning water into the cleaning water drain tank 131. The washing water drain tank 131 is a container having a substantially rectangular cross section that is disposed below the transport roller 111 and has an open top. The cleaning water drain tank 131 discharges the used cleaning water from the drain pipe 136. In this example, unlike the cleaning liquid supply device 12, the cleaning water is not reused.

Next, the cleaning operation (cleaning method) will be described.
The V-type filter 1 placed on the transport roller 111 is transferred to the cleaning zone 5. The position of the V-type filter 1 in the cleaning zone 5 is grasped by optical means or mechanical means (both not shown). As a result, the transport roller 111 moves the V-type filter 1 at a point where the position of the first trough in the transfer direction of the V-type filter 1 coincides with the position of the support bar 153 on the surface side of the cleaning surface of the V-type filter 1. Stop the transfer.

  When the transfer of the V-type filter 1 by the transport roller 111 is stopped, the cleaning liquid ejecting unit 14 is inserted into the upper portion of the valley of the V-type filter 1 by the ejecting unit moving device 15. By these moving operations, the cleaning liquid ejecting unit 14 and the V-type filter 1 to be cleaned are relatively positioned. Thereafter, the cleaning liquid supplied from the cleaning liquid supply device 12 is ejected from the cleaning liquid ejecting unit 14 onto the V-type filter 1. While the cleaning liquid ejecting unit 14 ejects the cleaning liquid, the ejecting unit moving device 15 moves the upper part of the valley of the V-type filter 1 from the lower part to finish the cleaning of the first trough in the transfer direction of the V-type filter 1. To do.

  When the cleaning of the first trough in the transfer direction of the V-type filter 1 is completed, the cleaning liquid ejecting unit 14 is moved in a direction away from the trough of the V-type filter 1 by the ejection unit moving device 15. When the ejection unit moving device 15 is moved in a direction away from the valley of the V-type filter 1, the transport roller 111 next moves the position of the first valley in the transfer direction on the back of the V-type filter 1 and the V-type filter. The transfer of the V-type filter 1 is stopped at a point where the position of the support bar 153 on the back side of the cleaning surface 1 coincides.

  When the transfer of the V-type filter 1 by the transport roller 111 is stopped, the cleaning liquid ejecting unit 14 is inserted into the upper portion of the valley of the V-type filter 1 by the ejecting unit moving device 15. By these moving operations, the cleaning liquid ejecting unit 14 and the V-type filter 1 to be cleaned are relatively positioned. Thereafter, the cleaning liquid supplied from the cleaning liquid supply device 12 is ejected from the cleaning liquid ejecting unit 14 onto the V-type filter 1. While the cleaning liquid spraying unit 14 sprays the cleaning liquid, the spraying unit moving device 15 moves the top of the valley of the V-type filter 1 from the bottom to the bottom of the V-type filter 1 to clean the first trough in the transfer direction on the back surface. finish.

  When the cleaning of the first trough in the transfer direction on the back surface of the V-type filter 1 is completed, the cleaning liquid ejecting unit 14 is moved in a direction away from the trough of the V-type filter 1 by the ejecting unit moving device 15. This operation is repeated to clean all the valleys on the front and back surfaces of the V-type filter 1.

  When the cleaning with the cleaning liquid supplied from the cleaning liquid supply device 12 is completed, the V-type filter 1 is transferred by the transport roller 111 and moves to cleaning with the cleaning water supplied from the cleaning water supply device 13. The cleaning operation is the same as the cleaning with the cleaning liquid supplied from the cleaning liquid supply device 12. When the cleaning with the cleaning water supplied from the cleaning water supply device 13 is finished, the V-type filter 1 is transferred to the outside of the cleaning zone 5 by the transport roller 111, and the cleaning of the V-type filter 1 is completed.

<Injection pipe cleaning method>
In this invention, the device which can wash | clean the inside of the injection pipe 142 easily is made | formed, and it demonstrates below. FIG. 9 is an overall view of the injection pipe 142 showing that the foreign matter 4 is accumulated inside the injection pipe 142. FIG. 9 shows the injection pipe 142 that has been cleaned and removed from the pipe connection port 143b. The foreign matter 4 is accumulated in the injection pipe 142.

  On the other hand, FIG. 10 is an operation diagram showing a method for removing the foreign matter 4 accumulated in the injection pipe 142. As shown in FIG. 10, high-pressure gas, high-pressure water, or the like is flowed from either the first pipe 142a side or the second pipe 142b side of the removed injection pipe 142. Thereby, high-pressure gas, high-pressure water, or the like escapes from either the first pipe 142a side or the second pipe 142b side to the other. At this time, the foreign matter 4 is also carried out of the injection pipe 142 at the same time.

  In the filter cleaning apparatus 10 according to the first embodiment, the shape of the injection pipe 142 is substantially U-shaped, and when the injection pipe 142 is inserted into the connection housing 143, the third pipe 142c is a V-type. Since it faces the filter 1, the tip of the injection pipe 142 is not directed to the filter medium 2 of the V-type filter 1. Thereby, it can prevent that the front-end | tip of the pipe 142 for injection pierces the filter medium 2 of the V-type filter 1. Furthermore, cutting of the fibers of the filter medium 2 by the injection pipe 142 can also be prevented. Moreover, since the filter medium 2 is not damaged, it is possible to prevent a decrease in the foreign matter collecting ability of the V-type filter 1.

  Moreover, since the injection hole 141 is provided in all of the 1st pipe 142a, the 2nd pipe 142b, and the 3rd pipe 142c, the washing | cleaning-liquid injection range can be expanded rather than the conventional rod-shaped pipe. As a result, the cleaning time can be shortened.

  Furthermore, since the shape of the injection pipe 142 is substantially U-shaped and does not require precision machining, an increase in cost can be suppressed. The injection pipe 142 can be attached to and detached from the pipe connection port 143b, and the removed injection pipe 142 can be easily cleaned. As a result, the injection pipe 142 is not disposable and can prevent economic deterioration.

  As described above, according to the first embodiment, the filter cleaning device has the U-shaped injection pipe that can be attached to and detached from the cleaning liquid injection unit. By providing such a structure, the U-shaped injection pipe does not damage the filter medium. In addition, the inside of the injection pipe can be cleaned. Furthermore, since the fine holes are provided on all the surfaces of the U-shaped pipe, it is possible to widen the cleaning area for one time. As a result, the cleaning time can be shortened without damaging the filter medium, and further, an effect of preventing an increase in cost and deterioration in economic efficiency can be obtained.

Embodiment 2. FIG.
In the first embodiment, the injection holes 141 of the same size are formed on both surfaces of the injection pipe 142. On the other hand, in the second embodiment, a case will be described in which injection holes 141 having different sizes are formed on both surfaces of the injection pipe 142.

  FIG. 11 is an enlarged view showing the cleaning liquid ejecting section 14 in the second embodiment. As shown in FIG. 11, the injection pipe 142 has an injection hole 141 that becomes larger from the connection housing 143 side of the first pipe 142a and the second pipe 142b toward the center of the third pipe 142c. ing. Although not visible in FIG. 11, the injection holes 141 are formed on both surfaces of the injection pipe 142 so as to increase from the connection housing 143 side of the first pipe 142a and the second pipe 142b toward the center of the third pipe 142c. It has been. Other configurations are the same as those of the first embodiment.

  The amount of the cleaning liquid ejected from the ejection hole 141 is determined by the amount and pressure of the cleaning liquid supplied to the cleaning liquid ejection unit 14 and the size of the ejection hole 141. Therefore, by changing the size of the injection hole 141, the flow rate distribution of the cleaning liquid to be injected can be freely set.

  For example, as shown in the first embodiment, the size of the injection hole 141 provided in the injection pipe 142 is the same size. At this time, when the amount of the cleaning liquid supplied to the cleaning liquid injection unit 14 is large and the pressure is high, the amount of liquid injected from the injection hole 141 is the first pipe 142a, the second pipe 142b, and the third pipe. 142c is almost equal in all locations. However, when the amount of the cleaning liquid supplied to the cleaning liquid spraying unit 14 is small and the pressure is low, the amount of liquid sprayed from the spray hole 141 is the value on the connection housing 143 side of the first pipe 142a and the second pipe 142b. More and less as you go to the third pipe 142c.

  Further, since the V-type filter 1 has the filter medium 2 folded in a pleat shape folded in a bellows shape, as shown in FIG. 6, the folded portion of the valley portion of the V-type filter 1 is very narrow. . In order to inject the cleaning liquid onto the filter medium 2 in such a valley, it is necessary to make the distance between the injection pipe 142 and the filter medium 2 close to about 5 mm. When thin fibers having a fiber diameter of several μm to 10 μm are used for the filter medium 2 of the V-type filter 1, the fibers may be cut if the injection from the injection holes 141 is strong.

  In the filter cleaning apparatus 10 according to the second embodiment, as shown in FIG. 11, the first pipe 142a and the second pipe 142b increase from the connection housing 143 side toward the center of the third pipe 142c. It is conceivable to use an injection pipe 142 having an injection hole 141 formed therein. As a result, even when the amount of cleaning liquid is small and the pressure is low, the amount of liquid to be ejected can be made almost equal at all locations of the first pipe 142a, the second pipe 142b, and the third pipe 142c. .

  Further, it is possible to prevent the injection speed from becoming too high as it goes from the connection housing 143 side of the first pipe 142a and the second pipe 142b toward the center of the third pipe 142c. Thereby, it can prevent that the filter medium 2 of the V-type filter 1 is damaged, and the fall of the foreign material collection capability of the V-type filter 1 can be prevented.

  As described above, according to the second embodiment, the filter cleaning device has an injection hole that becomes larger from the connection housing side of the first pipe and the second pipe toward the center of the third pipe. Yes. By providing such a configuration, the amount of liquid ejected from the fine holes and the ejection speed can be adjusted in accordance with the V-type filter to be cleaned. As a result, it is possible to prevent the filter medium of the V-type filter from being damaged, and it is possible to obtain an effect that it is possible to prevent a decrease in the foreign matter collecting ability of the V-type filter.

  Since the second moving mechanism 152 is a mechanism for moving the support bar 153 in the vertical direction of the cleaning apparatus 10, the cleaning liquid ejecting unit 14 is moved in the vertical direction by the second moving mechanism 152. At this time, the V-type filter 1 is disposed such that one of the cleaning surfaces is in contact with the transport roller 111. That is, it is placed on the transport roller 111 so that the direction of the valley of the V-type filter 1 and the horizontal direction of the cleaning device 10 coincide. Further, the V-type filter 1 is placed on the conveying roller 111 so that the injection pipe 142 of the cleaning liquid injection unit 14 can be inserted into the valley of the V-type filter 1.

  As a result, the injection pipe 142 can be inserted into the valley of the V-type filter 1. Therefore, it is possible to inject the cleaning liquid and the cleaning water from the injection pipe 142 to the valley portion of the V-type filter 1, and the inside of the V-type filter 1 can be cleaned. In the seventh embodiment, since the second moving mechanism 152 plays the role of the first moving mechanism 151, the first moving mechanism 151 is not provided. Other configurations are the same as those of the first embodiment.

  In the cleaning device 10 having such a configuration, since the cleaning liquid and the cleaning water are sprayed from above the V-type filter 1 placed on the transport roller 111, the surface of the V-type filter 1 on the side in contact with the transport roller 111 is removed. It cannot be washed directly. However, if the V-type filter 1 is turned over and cleaned again, the V-type filter 1 can be cleaned from both sides, and the cleaning power can be further increased.

  Therefore, a transport device 11 as shown in FIG. 18 is used. FIG. 18 is a top view showing the transfer device 11 using the filter cleaning device 10 of FIG.

  The filter charging tank 112 is a part where the V-type filter 1 is placed in the cleaning zone 5. For this reason, the filter charging tank 112 is not covered with the waterproof outer frame 6. The V-type filter 1 put from the filter charging tank 112 is sent to the cleaning tank 113 along the direction of arrow E in FIG. The filter charging tank 112 and the cleaning tank 113 are connected in a straight line.

  The cleaning tank 113 is a part for cleaning the V-type filter 1 with a cleaning liquid. The V-type filter 1 cleaned with the cleaning liquid in the cleaning tank 113 is sent to the rinsing tank 114. Rinse tank 114 is arranged at a position bent 90 degrees with respect to cleaning tank 113. Therefore, a direction changing tank 117 for bending the traveling direction of the V-type filter 1 by 90 degrees is provided between the cleaning tank 113 and the rinsing tank 114. Thereby, the moving direction of the V-type filter 1 sent to the rinsing tank 114 is in the direction of arrow F in FIG.

  The rinsing tank 114 is a portion through which the cleaning liquid adhering to the V-type filter 1 flows with cleaning water. The V-type filter 1 in which the cleaning liquid is flowed by the cleaning water in the rinsing tank 114 is sent to the dehydration tank 115. The dehydrating tank 115 is disposed at a position bent 90 degrees with respect to the rinsing tank 114. At this time, the dehydrating tank 115 is disposed at a position bent so as to face the cleaning tank 113.

The V-type filter 1 from which water has been removed in the dehydration tank 115 is sent to the filter carry-out tank 116 along the arrow G direction. The dewatering tank 115 and the filter carry-out tank 116 are connected in a straight line.

  The filter carry-out tank 116 is a part for taking out the cleaned V-type filter 1 from the cleaning zone 5. For this reason, the filter carry-out tank 116 is not covered with the waterproof outer frame 6. Accordingly, the transport device 11 has a substantially U-shaped cross section (substantially U-shaped cross section).

  As described above, according to the seventh embodiment, the conveying device has a shape in which the washing tank, the rinsing tank, and the dehydrating tank are bent into a substantially U-shaped cross section by the direction changing tank. Further, when the V-type filter is put in the filter cleaning apparatus, the V-type filter is disposed so that one of the cleaning surfaces is in contact with the transport roller. By providing such a configuration, the distance between the filter introduction tank and the filter carry-out tank is reduced. Thereby, in order to wash | clean the surface which is not wash | cleaned of the V-type filter collect | recovered by the filter carrying-out tank, the operation | movement which can reverse a V-type filter in a filter washing | cleaning apparatus again can be performed easily. As a result, both surfaces of the V-type filter can be easily cleaned.

  Moreover, since the distance between the filter loading tank and the filter unloading tank is short, one worker can perform the filter loading work and the filter collecting work. Thereby, the work involved in cleaning the V-type filter can be performed by a small number of people.

  In addition, either one of the cleaning surfaces is disposed in contact with the conveyance roller. This suppresses the displacement of the position of the V-type filter on the conveying roller as compared with the case where the valley of the V-type filter is aligned with the vertical direction of the cleaning device and then transferred on the conveying roller. Can do. As a result, even if the conveyance direction of the V-type filter is changed by 90 degrees in the middle of the conveyance device, the conveyance path of the V-type filter is reproduced, and the valley portion of the V-type filter whose traveling direction is changed by 90 degrees The injection pipe can be surely inserted.

  In the filter carry-out tank 116 according to the seventh embodiment, the V-type filter 1 is inclined so that the V-type filter 1 is inclined so that the V-type filter 1 is inclined upside down. You may provide the mechanism to do.
