Description
本発明は、洗浄後の、濾材に水分を含むフィルタを脱水する脱水装置及び脱水方法の改良に関する。 The present invention relates to an improvement in a dewatering apparatus and a dewatering method for dewatering a filter containing water in a filter medium after washing.
一般的に、建物の空気調和機などの空気取入口には、周縁に枠が形成された網状フィルタが設けられ、このフィルタが、空気調和機に吸入された空気に含まれる塵埃などを捕集して空気を濾過することが知られている。フィルタは、塵埃などの異物がフィルタ面に付着するため、一定期間ごとにフィルタを空気取入口から外して洗浄し、その後に脱水及び乾燥させて再使用される例がある。 Generally, an air inlet of a building air conditioner or the like is provided with a mesh filter having a frame formed at the periphery, and this filter collects dust contained in the air sucked into the air conditioner. It is known to filter air. Since foreign matters such as dust adhere to the filter surface, the filter may be reused by removing the filter from the air intake at regular intervals and then dehydrating and drying.
洗浄後の網状フィルタの脱水は、例えば、遠心分離による脱水より行なわれる。また、これらのフィルタの脱水作業は手作業もしくは半自動で行われる。 The dewatering of the mesh filter after washing is performed by, for example, dehydration by centrifugation. Further, the dewatering operation of these filters is performed manually or semi-automatically.
下記特許文献１には、空調用フィルタの乾燥時間及び清掃の作業時間を短縮する空調用フィルタの乾燥装置が開示されている。この文献においては、乾燥装置が、第一チャンバの内部を加熱し、空調用フィルタに含まれる水分の蒸発を促進する加熱手段と、第二チャンバの内部を冷却し、第二チャンバ内に含まれる水蒸気の凝縮を促進する冷却手段とを有する。そして、加熱手段と冷却手段とが冷媒を介して接続されており、第二チャンバから第一チャンバに熱が移動することが開示されている。 Patent Document 1 listed below discloses an air conditioning filter drying device that shortens the drying time of the air conditioning filter and the cleaning work time. In this document, the drying apparatus heats the inside of the first chamber and accelerates the evaporation of moisture contained in the air conditioning filter, and cools the inside of the second chamber and is contained in the second chamber. Cooling means for promoting condensation of water vapor. And it is disclosed that the heating means and the cooling means are connected via a refrigerant, and heat is transferred from the second chamber to the first chamber.
また、中性能或いは高性能な空調用フィルタとして、濾材を用いた空調用フィルタが採用される例がある。この濾材を用いた空調用フィルタは、プレフィルタとして網状フィルタを装着して塵埃などを捕集した後、空気中の微細な粉塵や油成分などまでも捕集する。この濾材は化学繊維を主体とした多孔質の不織布などからなり、その網目状構造により空気中の微細な粉塵や油成分などを捕集する。この不織布などを用いたフィルタ濾材は、捕集面積を広げるためにプリーツ状に折り曲げられた構造となっている。なお、本明細書では、空調用フィルタが捕集する空気中の微細な粉塵や油成分などを「異物」と総称する。 Further, there is an example in which an air conditioning filter using a filter medium is employed as a medium performance or high performance air conditioning filter. The air-conditioning filter using the filter medium collects dust and the like after attaching a mesh filter as a pre-filter, and also collects fine dust and oil components in the air. This filter medium is made of a porous nonwoven fabric mainly composed of chemical fibers, and collects fine dust and oil components in the air by its network structure. The filter medium using this nonwoven fabric or the like has a structure that is folded into a pleat shape in order to widen the collection area. In the present specification, fine dust and oil components in the air collected by the air conditioning filter are collectively referred to as “foreign substances”.
従来、この空調用フィルタはこの濾材の洗浄の難しさから使い捨てされていたが、環境問題への関心の高まりにより洗浄再生させて再使用する試みが研究され、空調用フィルタを回収して洗浄し、その後脱水・乾燥させる自動化された脱水・乾燥方法が提案されている。 Conventionally, this air conditioning filter has been thrown away due to the difficulty of cleaning this filter medium. However, due to increasing concern about environmental problems, attempts have been made to recycle and reuse the filter, and the air conditioning filter is recovered and cleaned. Then, an automated dehydration / drying method for dehydration / drying has been proposed.
下記特許文献２には、空調用エアフィルタの自動化された脱水及び乾燥装置が開示されている。ここでは、搬送手段によるフィルタの搬送経路に沿って、圧縮空気噴射手段と集塵機を設けたエアー洗浄ゾーン、高圧水噴射手段を設けた水洗浄ゾーン及び温風発生手段を設けた乾燥ゾーンを順次配置し、乾燥ゾーンでは、フィルタは乾燥室内に入り、そこでヒーターとファンとから成る温風発生手段の温風により脱水及び乾燥された後、乾燥室から出して再使用に供されることが開示されている。 Patent Document 2 below discloses an automated dehydration and drying device for an air filter for air conditioning. Here, an air cleaning zone provided with compressed air injection means and a dust collector, a water cleaning zone provided with high-pressure water injection means, and a drying zone provided with hot air generation means are sequentially arranged along the filter transfer path by the transfer means. In the drying zone, the filter enters the drying chamber, where it is dehydrated and dried by the hot air generated by the hot air generating means composed of a heater and a fan, and is then discharged from the drying chamber for reuse. ing.
上述したような遠心分離によるフィルタの脱水については、装置が大型化し、多様な形状のフィルタへ対応が難しいという問題がある。また、フィルタを連続的に処理することができず、一回の脱水作業で可能なフィルタの枚数も限られるため生産性に劣るという問題がある。さらに、過剰な遠心力によりフィルタが破損する可能性がある。 Regarding the dehydration of the filter by centrifugation as described above, there is a problem that the apparatus becomes large and it is difficult to cope with filters of various shapes. In addition, the filter cannot be processed continuously, and the number of filters that can be processed in one dehydration operation is limited, resulting in poor productivity. Furthermore, the filter may be damaged by excessive centrifugal force.
さらに、上述したように中性能或いは高性能な空調用フィルタに用いられる濾材は、化学繊維を主体とした多孔質の不織布などからなり、繊維の網目状構造と濾材をプリーツ状に折り曲げた構造により空気中の微細な粉塵や油成分などを大量に捕集する。そのため、洗浄後のフィルタにおいても、密に織り込まれた濾材内部に大量の水が残留するとともに、その水を濾材内部から連続的に脱水することは難しいという問題がある。 Further, as described above, the filter medium used in the medium-performance or high-performance air conditioning filter is composed of a porous nonwoven fabric mainly composed of chemical fibers, and has a fiber network structure and a structure in which the filter medium is bent into a pleat shape. Collects large amounts of fine dust and oil components in the air. Therefore, even in the filter after washing, there is a problem that a large amount of water remains in the densely woven filter medium and it is difficult to continuously dehydrate the water from the filter medium.
本発明の目的は、濾材がプリーツ状に折り曲げられた中性能或いは高性能な空調フィルタにおいても、洗浄後のフィルタの濾材内部に含まれる水分を短時間に効率よく取り除くことができるフィルタの脱水装置及び脱水方法を提供することにある。 An object of the present invention is to provide a filter dewatering device capable of efficiently removing moisture contained in the filter medium after cleaning in a short time, even in a medium-performance or high-performance air-conditioning filter in which the filter medium is bent into a pleat shape. And providing a dehydration method.

It is characterized by.
また、上部及び下部の吸水ローラには、軸方向に間隔をあけて切り込みが形成されていることを特徴とする。 Further, the upper and lower water absorption rollers are characterized in that cuts are formed at intervals in the axial direction.

Can be removed.
以下に、図面を用いて本発明に係るフィルタの脱水装置の実施形態について、図を用いて詳細に説明する。図１は、本実施形態におけるフィルタの脱水装置の概略構成を側面から示す図であり、図２は、図１のＡ−Ａ線による断面図である。 Hereinafter, an embodiment of a filter dehydrating apparatus according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram illustrating a schematic configuration of a filter dehydrating apparatus according to the present embodiment from the side, and FIG. 2 is a cross-sectional view taken along line AA of FIG.
フィルタの脱水装置１は、洗浄後のフィルタ２を脱水する装置である。フィルタ２は、化学繊維を主体とした多孔質の不織布などからなる濾材を用いた空調用フィルタであり、中性能或いは高性能な空調用フィルタである。このフィルタ２は、例えば、建物の空気調和機などの空気取入口に取り付けられ、吸入された空気に含まれる塵埃などの異物を捕集して空気を濾過する。従って、このフィルタ２は、塵埃などの異物がフィルタ２に付着して空気を濾過する能力が低下するため、所定の期間ごとにフィルタ２を空気取入口から外してフィルタの洗浄装置（図示せず）により洗浄され、その後に脱水装置１により脱水される。 The filter dewatering device 1 is a device that dehydrates the washed filter 2. The filter 2 is an air conditioning filter using a filter medium made of a porous nonwoven fabric mainly composed of chemical fibers, and is a medium performance or high performance air conditioning filter. The filter 2 is attached to, for example, an air intake of a building air conditioner or the like, and collects foreign matters such as dust contained in the sucked air and filters the air. Accordingly, since the filter 2 has a reduced ability to filter air due to foreign matters such as dust adhering to the filter 2, the filter 2 is removed from the air intake port every predetermined period (not shown). ) And then dehydrated by the dehydrator 1.
この濾材を用いたフィルタ２の厚みｄは、約１０ｍｍ〜約５００ｍｍの範囲であり、その網目状構造により空気中の微細な粉塵や油成分などまでも捕集する。フィルタ２は、その縦横の大きさにより単一個、或いは複数個が洗浄用の枠材に収められて搬送機構であるコンベア３に搭載されて洗浄装置（図示せず）により洗浄され、その後に脱水装置１により脱水されて再度空調用フィルタとして使用される。 The thickness d of the filter 2 using this filter medium is in the range of about 10 mm to about 500 mm, and even fine dust and oil components in the air are collected by the network structure. Depending on the vertical and horizontal sizes of the filter 2, a single or a plurality of filters 2 are housed in a cleaning frame member, mounted on a conveyor 3 as a transport mechanism, cleaned by a cleaning device (not shown), and then dehydrated. It is dehydrated by the device 1 and used again as a filter for air conditioning.
本実施形態に係るフィルタの脱水装置１は、濾材の水分を吸収する吸収部材４，５と、フィルタ２に対して吸収部材４，５を押し付ける動作と離隔する動作とを繰り返すように移動させる移動機構６とを有する。 The filter dehydrating apparatus 1 according to the present embodiment moves so as to repeat the absorbing members 4 and 5 that absorb the moisture of the filter medium and the operation of pressing the absorbing members 4 and 5 against the filter 2 and the separating operation. And a mechanism 6.
移動機構６は、押し付け動作の際に、濾材が変形するまで吸水部材４を移動させ、これにより濾材内の水分を凝集させて、吸水部材４，５と濾材間に水の通路を形成させる。一方、移動機構１０は、離隔する動作の際に、濾材の変形を戻しフィルタ２から離れるように吸水部材５を移動させ、これにより濾材の変形が戻る際に吸水部材４，５と濾材が接触している部分に水分量の少ない領域が形成されるため、前記水の通路を通って毛細管現象により吸水部材４，５へ濾材の水分を吸収させる。 During the pressing operation, the moving mechanism 6 moves the water absorbing member 4 until the filter medium is deformed, thereby aggregating moisture in the filter medium and forming a water passage between the water absorbing members 4 and 5 and the filter medium. On the other hand, the moving mechanism 10 returns the deformation of the filter medium and moves the water absorption member 5 away from the filter 2 during the separation operation, and the water absorption members 4 and 5 come into contact with the filter medium when the deformation of the filter medium returns. Since a region with a small amount of moisture is formed in the portion where the water is passed, the moisture of the filter medium is absorbed by the water-absorbing members 4 and 5 by capillary action through the water passage.
このような移動機構の動作、すなわちフィルタ２に対して吸収部材４，５が接離する動作により、濾材内の水分が短時間に効率よく吸収部材４，５に移動することができ、フィルタ２を脱水することができる。このような吸収部材４，５の接離動作を繰り返すことにより、濾材からより多くの水分を取り除くことができる。 By such an operation of the moving mechanism, that is, an operation in which the absorbing members 4 and 5 are brought into and out of contact with the filter 2, the moisture in the filter medium can be efficiently moved to the absorbing members 4 and 5 in a short time. Can be dehydrated. By repeating the contact / separation operation of the absorbing members 4 and 5, more water can be removed from the filter medium.
次に、脱水装置１の具体的な構成について説明する。脱水装置１は、フィルタ２を一方向Ｂへ搬送する搬送機構であるコンベア３と、フィルタ２の濾材に含まれる水分を吸収する吸収部材４，５と、フィルタ２に対して吸収部材を押し付ける動作と離隔する動作とを繰り返すように移動させる移動機構６と、コンベア３と吸収部材４，５と移動機構６とを収容するケーシング７とを有する。 Next, a specific configuration of the dehydrator 1 will be described. The dehydrating apparatus 1 is a conveyor 3 that is a transport mechanism for transporting the filter 2 in one direction B, absorbing members 4 and 5 that absorb moisture contained in the filter medium of the filter 2, and an operation of pressing the absorbing member against the filter 2. And a moving mechanism 6 that moves so as to repeat the separation, and a casing 7 that houses the conveyor 3, the absorbing members 4, 5, and the moving mechanism 6.
吸水部材４，５は、吸水材８がロール状に巻き付けられた吸水ローラであり、フィルタ２を挟んで上下に配置される。以降、フィルタ２の上側に設けられている吸水部材を、上部の吸水ローラ４と記載し、フィルタ２の下側に設けられている吸水部材を、下部の吸水ローラ５と記載する。 The water-absorbing members 4 and 5 are water-absorbing rollers in which the water-absorbing material 8 is wound in a roll shape, and are arranged vertically with the filter 2 interposed therebetween. Hereinafter, the water absorbing member provided on the upper side of the filter 2 is referred to as an upper water absorbing roller 4, and the water absorbing member provided on the lower side of the filter 2 is referred to as a lower water absorbing roller 5.
上部及び下部の吸水ローラ４，５は、一方向（矢印Ｂの方向）に間隔をあけてそれぞれ複数配置される。上部及び下部の吸水ローラ４，５は、フィルタ２を上下方向に挟み込んでフィルタ２の濾材内部に含まれた水分を吸水する。吸水材８は、例えば、ポリビニルアルコール（ＰＶＡ）などの吸水性樹脂、或いは親水性樹脂からなるが、これに限らず、吸水性或いは親水性を有する素材であれば良い。また、吸水部材は吸水ローラの形態に限らず、例えば、平板状、ベルト状の吸水材が設けられた形態などであっても良い。また、吸水部材に使用される吸水ローラは、上部の吸水ローラ４の片方のみを設置した形式とすることもできる。また、上部の吸水ローラ４は、複数配置される場合について説明したが、この数に限定されず１つであっても良い。 A plurality of upper and lower water-absorbing rollers 4 and 5 are arranged at intervals in one direction (the direction of arrow B). The upper and lower water absorption rollers 4 and 5 sandwich the filter 2 in the vertical direction and absorb water contained in the filter medium of the filter 2. The water absorbing material 8 is made of, for example, a water absorbing resin such as polyvinyl alcohol (PVA) or a hydrophilic resin, but is not limited thereto, and may be a material having water absorbing property or hydrophilic property. Further, the water absorbing member is not limited to the form of the water absorbing roller, and may be, for example, a form in which a flat or belt-like water absorbing material is provided. Moreover, the water absorption roller used for a water absorption member can also be made into the type which installed only one side of the upper water absorption roller 4. FIG. Moreover, although the upper water absorption roller 4 demonstrated the case where two or more were arrange | positioned, it is not limited to this number, One may be sufficient.
搬送機構であるコンベア３は、左右のローラ９ａ，９ｂと、これらのローラ９ａ，９ｂに巻き掛けられたベルト１０とを有するベルトコンベアからなる。ベルト１０上には下部の吸水ローラ５がベルト１０に接するように設けられている。コンベア３の駆動部（図示せず）の駆動により、ローラ９ａ，９ｂとベルト１０を介して、下部の吸水ローラ５が回転する。この下部の吸水ローラ５の回転によって、下部の吸水ローラ５に載せられたフィルタ２が図１中の矢印Ｂの方向に搬送される。 The conveyor 3 serving as a transport mechanism includes a belt conveyor having left and right rollers 9a and 9b and a belt 10 wound around the rollers 9a and 9b. A lower water absorption roller 5 is provided on the belt 10 so as to be in contact with the belt 10. By driving a drive unit (not shown) of the conveyor 3, the lower water absorption roller 5 is rotated via the rollers 9 a and 9 b and the belt 10. Due to the rotation of the lower water absorption roller 5, the filter 2 placed on the lower water absorption roller 5 is conveyed in the direction of arrow B in FIG.
移動機構６は、図１，２に示すように、架台１１に取り付けられた上部の吸水ローラ４を、支持棒１２を介して上下方向Ｃに駆動させる駆動装置１３を有する。この移動機構６は、駆動装置１３による下降動作により、上部の吸水ローラ４をフィルタ２に押し付け、駆動装置１３による上昇動作により、上部の吸水ローラ４をフィルタ２から離隔する。 As shown in FIGS. 1 and 2, the moving mechanism 6 includes a driving device 13 that drives the upper water absorption roller 4 attached to the gantry 11 in the vertical direction C via the support rod 12. The moving mechanism 6 presses the upper water absorbing roller 4 against the filter 2 by the lowering operation by the driving device 13, and separates the upper water absorbing roller 4 from the filter 2 by the raising operation by the driving device 13.
図３に、上部及び下部の吸水ローラ４，５とフィルタ２の詳細な構成を示す。フィルタ２は、濾材１４と、濾材１４を取り囲む枠１６とを有する。濾材１４は、化学繊維を主体とした多孔質の不織布１８をプリーツ状に折り曲げて構成されている。濾材１４は、吸水材８よりも硬く形成される。言い換えれば、吸水材８の材質は濾材１４よりも柔らかい。洗浄後のフィルタ２には、不織布１８の隙間に大量の水分が含まれている。上述したフィルタ２の厚みｄは、枠１６の厚みであり、図３に示す符号ｄ１は、濾材１４の厚みである。濾材１４の厚みｄ１は、枠１６の厚みｄより小さい。本実施形態においては、移動機構６により、上部及び下部の吸水ローラ４，５が、濾材１４が変形するまで濾材１４を押し付ける。この動作の際に、上部及び下部ローラ４，５が枠１６により妨げられないように、各吸水ローラ４，５には、軸方向に間隔をあけて切り込み２０が形成される。このため、この切り込み２０の間の吸水材８ごとに周方向に変形可能になっている。このような切り込み２０により、濾材１４と枠１６とで異なる厚みを有するフィルタ２の形状に対応するように吸収材８を変形させることができ、確実に、上部及び下部の吸水ローラ４，５によって、濾材１４が変形するまで濾材１４を押し付けることができる。また、このような切り込み２０が形成されることにより、サイズが異なるフィルタ２に対しても、上部及び下部の吸水ローラ４，５によって、濾材１４が変形するまで濾材１４を押し付けることができる。 FIG. 3 shows a detailed configuration of the upper and lower water absorbing rollers 4 and 5 and the filter 2. The filter 2 includes a filter medium 14 and a frame 16 surrounding the filter medium 14. The filter medium 14 is configured by bending a porous nonwoven fabric 18 mainly composed of chemical fibers into a pleat shape. The filter medium 14 is formed to be harder than the water absorbing material 8. In other words, the water absorbing material 8 is softer than the filter medium 14. The filter 2 after cleaning contains a large amount of moisture in the gaps between the nonwoven fabrics 18. The thickness d of the filter 2 described above is the thickness of the frame 16, and the symbol d <b> 1 shown in FIG. 3 is the thickness of the filter medium 14. The thickness d1 of the filter medium 14 is smaller than the thickness d of the frame 16. In the present embodiment, the moving mechanism 6 causes the upper and lower water absorption rollers 4 and 5 to press the filter medium 14 until the filter medium 14 is deformed. In order to prevent the upper and lower rollers 4, 5 from being obstructed by the frame 16 during this operation, the water absorbing rollers 4, 5 are formed with notches 20 at intervals in the axial direction. For this reason, each water absorbent 8 between the cuts 20 can be deformed in the circumferential direction. With such a cut 20, the absorbent 8 can be deformed so as to correspond to the shape of the filter 2 having different thicknesses between the filter medium 14 and the frame 16, and reliably by the upper and lower water absorption rollers 4, 5. The filter medium 14 can be pressed until the filter medium 14 is deformed. Further, by forming such a cut 20, the filter medium 14 can be pressed against the filters 2 having different sizes until the filter medium 14 is deformed by the upper and lower water absorption rollers 4 and 5.
次に、移動機構６の動作による吸水ローラ４，５の機能について、図４から９を用いて具体的に説明する。図４は、上部及び下部の吸水ローラ４，５がフィルタ２を押し付ける前の状態を示す図であり、図５は、上部及び下部の吸水ローラ４，５がフィルタ２を押し付ける途中の状態を示す図であり、図６は、上部及び下部の吸水ローラ４，５がフィルタ２を押し付けたときの状態を示す図であり、図７は、上部及び下部の吸水ローラ４，５がフィルタ２から離隔する途中の状態を示す図であり、図８は、吸水材の内部の様子を示す拡大図であり、図９は、上部及び下部の吸水ローラ４，５がフィルタ２から離隔したときの状態を示る。 Next, the function of the water absorbing rollers 4 and 5 by the operation of the moving mechanism 6 will be specifically described with reference to FIGS. FIG. 4 is a view showing a state before the upper and lower water absorption rollers 4 and 5 press the filter 2, and FIG. 5 shows a state where the upper and lower water absorption rollers 4 and 5 are pressing the filter 2. FIG. 6 is a view showing a state when the upper and lower water absorption rollers 4 and 5 press the filter 2, and FIG. 7 is a diagram showing that the upper and lower water absorption rollers 4 and 5 are separated from the filter 2. FIG. 8 is an enlarged view showing the inside of the water-absorbing material, and FIG. 9 shows the state when the upper and lower water-absorbing rollers 4 and 5 are separated from the filter 2. Show.
まず、移動機構６は、上部の吸水ローラ４とフィルタ２との間隔を調整する。すなわち、コンベア３により搬送されるフィルタ２の上下方向の厚みｄは、約１０ｍｍ〜約５００ｍｍの範囲であり、駆動装置１３は、このフィルタ２の上下方向の厚みｄに対して最適な高さ方向の位置を設定する。すなわち、駆動装置１３は、昇降することでフィルタ２を上部の吸水ローラ４と下部の吸水ローラ５とにより挟み込ませる位置に調整する。すなわち、図４に示されるように、移動機構６により、フィルタ２を構成するプリーツ状に折り畳まれた濾材１４が上部及び下部の吸水ローラ４，５の間に挟まるように、上部の吸水ローラ４の位置が調整される。この駆動装置１３には、ボールねじ（図示せず）が設けられ、サーボモータ（図示せず）によりＣ方向（図１，２）に昇降するが、他の方式、例えばロック・シリンダなどにより昇降させても良い。 First, the moving mechanism 6 adjusts the distance between the upper water absorption roller 4 and the filter 2. That is, the vertical thickness d of the filter 2 transported by the conveyor 3 is in the range of about 10 mm to about 500 mm, and the drive device 13 has an optimum height direction with respect to the vertical thickness d of the filter 2. Set the position of. That is, the drive device 13 moves up and down to adjust the filter 2 to a position where the filter 2 is sandwiched between the upper water absorption roller 4 and the lower water absorption roller 5. That is, as shown in FIG. 4, the upper water absorbing roller 4 so that the filter medium 14 folded in a pleat form constituting the filter 2 is sandwiched between the upper and lower water absorbing rollers 4, 5 by the moving mechanism 6. The position of is adjusted. This drive device 13 is provided with a ball screw (not shown), and is lifted and lowered in the C direction (FIGS. 1 and 2) by a servo motor (not shown). You may let them.
そして、図５に示されるように、移動機構６により、上部の吸水ローラ４がプリーツ状に折り畳まれた濾材１４に押し付けられる。このとき、プリーツ状に折り畳まれた濾材１４よりも上部の吸水ローラ４及び下部の吸水ローラ５の方が柔らかいため、先に上部の吸水ローラ４と下部の吸水ローラ５が圧縮変形する。 Then, as shown in FIG. 5, the upper water absorption roller 4 is pressed against the filter medium 14 folded in a pleat shape by the moving mechanism 6. At this time, since the upper water absorption roller 4 and the lower water absorption roller 5 are softer than the filter medium 14 folded in a pleat shape, the upper water absorption roller 4 and the lower water absorption roller 5 are first compressed and deformed.
移動機構６による押し付けがさらに進むと、図６に示されるように上部の吸水ローラ４と下部の吸水ローラ５における圧縮変形した箇所の変形が抑制され、濾材１４が押しつぶされて変形する。このため、濾材１４の厚さがｄ１からｄ２へと小さくなる。ここで、厚さｄ２は、厚さｄ１の８０％−９５％の大きさである。このような濾材１４の変形により、不織布１８間に含まれる各水分２０の距離が縮まり、そして凝集力により互いの水分が結合して、図６に示されるように各所で一体化される。また、上部及び下部の吸水ローラ４，５と、これらに接触する濾材１４の表面においては、濾材１４から各吸水ローラ４，５と連なる水の通路が形成される。 When the pressing by the moving mechanism 6 further proceeds, as shown in FIG. 6, the deformation of the compressed and deformed portions of the upper water absorbing roller 4 and the lower water absorbing roller 5 is suppressed, and the filter medium 14 is crushed and deformed. For this reason, the thickness of the filter medium 14 decreases from d1 to d2. Here, the thickness d2 is 80% to 95% of the thickness d1. Due to the deformation of the filter medium 14, the distance between the moistures 20 contained between the nonwoven fabrics 18 is reduced, and the moistures of each other are combined by the cohesive force, and are integrated at various places as shown in FIG. 6. Further, on the upper and lower water absorbing rollers 4 and 5 and the surface of the filter medium 14 in contact with the upper and lower water absorbing rollers 4 and 5, a water passage is formed from the filter medium 14 to the water absorbing rollers 4 and 5.
続いて、移動機構６により、図７に示されるように、上部の吸水ローラ４がフィルタ２から離隔される。このとき、上部の吸水ローラ４と下部の吸水ローラ５の方が、濾材１４よりも柔らかいため、先に形状が復元する。 Subsequently, as shown in FIG. 7, the upper water absorption roller 4 is separated from the filter 2 by the moving mechanism 6. At this time, since the upper water absorption roller 4 and the lower water absorption roller 5 are softer than the filter medium 14, the shape is restored first.
この上部の吸水ローラ４と下部の吸水ローラ５の形状が復元した箇所は、それまで圧縮変形していたことで水分が含まれていないため吸水力が高くなっている。すなわち、吸水材８の圧縮変形を生じた箇所は、図８の中央に示されるように吸水材８の樹脂膜５０で形成された水分２０を溜める多孔質領域５１が押しつぶされている。この多孔質領域５１の中には、水分２０とともに空気５２が入っているが（図８の左側）、圧縮変形で押しつぶされることで、水分２０と空気５２が排出される。圧縮変形を生じさせる力が除かれると多孔質領域５１が元の形状の戻ろうとするが、その際に変形していた多孔質領域５１は真空状態になるため、水分２０や空気５２を吸い込む力が生じる（図８の右側）。このため、図７に示されるように濾材１４の中に形成された水の通路を通じて、濾材１４の内部の水分２０が上部の吸水ローラ４と下部の吸水ローラ５の形状が復元した箇所に移動する。 The portion where the shapes of the upper water absorption roller 4 and the lower water absorption roller 5 are restored has high water absorption because it has been compressed and deformed so far and does not contain moisture. That is, the porous region 51 that accumulates the moisture 20 formed by the resin film 50 of the water absorbing material 8 is crushed at the location where the compressive deformation of the water absorbing material 8 occurs, as shown in the center of FIG. The porous region 51 contains air 52 together with the moisture 20 (left side in FIG. 8), but the moisture 20 and the air 52 are discharged by being crushed by compressive deformation. When the force that causes the compressive deformation is removed, the porous region 51 tries to return to its original shape, but the porous region 51 that has been deformed at that time is in a vacuum state, so the force that sucks in moisture 20 and air 52 (Right side of FIG. 8) occurs. For this reason, as shown in FIG. 7, through the water passage formed in the filter medium 14, the moisture 20 inside the filter medium 14 moves to a location where the shapes of the upper water absorption roller 4 and the lower water absorption roller 5 are restored. To do.
このような機構で濾材１４の内部から水分２０が吸水されるため、移動機構６によって上部の吸水ローラ４をフィルタ２から離隔させる速度は、吸水材８の圧縮変形した部分に吸水材８の圧縮変形していない箇所から水分２０が移動する速度よりも速くする必要がある。つまり、移動機構６を離隔させる速度が遅いと、圧縮変形した部分の吸水材８に圧縮変形していない吸水材８の箇所から水分が移動するため、濾材１４の水分を吸い取る力が弱くなる。このため、移動機構６による上部の吸水ローラ４をフィルタ２から離隔させる速度させる速度は、吸水材８の内部の水分が移動する速度よりも速くなるような構造とすることが必要である。 Since the moisture 20 is absorbed from the inside of the filter medium 14 by such a mechanism, the speed at which the upper water absorption roller 4 is separated from the filter 2 by the moving mechanism 6 is determined by the compression of the water absorption material 8 in the compressed and deformed portion of the water absorption material 8. It is necessary to make it faster than the speed at which the moisture 20 moves from an undeformed location. That is, when the speed at which the moving mechanism 6 is separated is slow, the moisture moves from the portion of the water absorbing material 8 that is not compressively deformed to the water absorbing material 8 that is compressed and deformed, so that the force of absorbing the moisture of the filter medium 14 is weakened. For this reason, the speed at which the upper water-absorbing roller 4 is separated from the filter 2 by the moving mechanism 6 needs to be faster than the speed at which the moisture inside the water-absorbing material 8 moves.
そして、上部の吸水ローラ４がフィルタ２から完全に離れると、図９に示されるように、濾材１４の厚さはｄ１に戻り、濾材１４内の少なくなった水分はまた不織布１８間に水滴として分離される。このような、フィルタ２に対して上部及び下部の吸水ローラ４，５を押し付ける動作と離隔する動作とを繰り返すことにより、濾材１４に含まれる水分２０が上部及び下部ローラ４，５へ吸水され、フィルタ２が脱水される。 Then, when the upper water absorption roller 4 is completely separated from the filter 2, the thickness of the filter medium 14 returns to d 1 as shown in FIG. 9, and the reduced water in the filter medium 14 is also dropped between the nonwoven fabrics 18 as water droplets. To be separated. By repeating the operation of pressing the upper and lower water absorption rollers 4 and 5 against the filter 2 and the operation of separating them, the moisture 20 contained in the filter medium 14 is absorbed by the upper and lower rollers 4 and 5. The filter 2 is dehydrated.
上記脱水作業により吸水ローラ４，５の吸水材８に含まれた水分２０を除去する動作について図１０，１１を用いて説明する。図１０は、上部及び下部の吸水ローラ４，５を互いに押し付けたときの状態を示す図であり、図１１は、上部及び下部の吸水ローラ４，５の絞り機構を示す説明図である。 The operation of removing the moisture 20 contained in the water absorbing material 8 of the water absorbing rollers 4 and 5 by the dehydration operation will be described with reference to FIGS. FIG. 10 is a diagram showing a state when the upper and lower water absorbing rollers 4 and 5 are pressed against each other, and FIG. 11 is an explanatory diagram showing a squeezing mechanism of the upper and lower water absorbing rollers 4 and 5.
上部及び下部の吸水ローラ４，５の間にあったフィルタ２が脱水され、コンベア３により脱水装置１から搬出されると、移動機構６は、図１０に示されるように、上部の吸水ローラ４を下部の吸水ローラ５に押し付けるように移動させる。そして、互いに押し付けられた吸水ローラ４，５では、吸水材８が圧縮変形して、そこに含まれる水分が絞り出され脱水が行われる。この作業が終了すると、次のフィルタ２の脱水作業に備え、移動機構６は、上部の吸水ローラ４を上昇させる。 When the filter 2 between the upper and lower water absorption rollers 4 and 5 is dehydrated and carried out of the dehydrator 1 by the conveyor 3, the moving mechanism 6 moves the upper water absorption roller 4 to the lower side as shown in FIG. The water absorbing roller 5 is moved so as to be pressed. And in the water absorption rollers 4 and 5 pressed against each other, the water absorption material 8 is compressed and deformed, and the water contained therein is squeezed out and dewatered. When this operation is completed, the moving mechanism 6 raises the upper water absorption roller 4 in preparation for the next dehydration operation of the filter 2.
図１１に、別の態様における吸水ローラ４，５の脱水作業の状態を示す。図１１では、上部の吸水ローラ４ａ，４ｂ及び下部の吸水ローラ５ａ，５ｂは、連続する２つの吸水ローラを取り出して記載する。上部の吸水ローラ４ａ，４ｂは上部絞りローラ２２を備える。そして、上部絞りローラ２２は、回転する上部の吸水ローラ４ａ，４ｂの吸水材８に押し当てられて吸水材８を圧縮変形させて、そこに含まれる水分が絞り出され脱水が行われる。同様に下部の吸水ローラ５ａ，５ｂは下部絞りローラ２４を備える。そして、下部絞りローラ２４は、回転する下部の吸水ローラ５ａ，５ｂの吸水材８に押し当てられて吸水材８を圧縮変形させて、そこに含まれる水分が絞り出され脱水が行われる。上部の吸水ローラ４ａ，４ｂと上部絞りローラ２２とが接触する部分には、水分が落下するのを防ぐための受け板２６が設けられている。上部の吸水ローラ４ａ，４ｂから絞り出された水分は、受け板２６によって下部の吸水ローラ５ａ，５ｂの端部に流され、下部の吸水ローラ５ａ，５ｂに落下してしまうことが防止される。 In FIG. 11, the state of the dehydration operation | work of the water absorption rollers 4 and 5 in another aspect is shown. In FIG. 11, the upper water absorption rollers 4a and 4b and the lower water absorption rollers 5a and 5b are described by taking out two continuous water absorption rollers. The upper water absorption rollers 4 a and 4 b include an upper squeezing roller 22. The upper squeezing roller 22 is pressed against the water absorbing material 8 of the rotating upper water absorbing rollers 4a and 4b to compress and deform the water absorbing material 8, and the water contained therein is squeezed out for dehydration. Similarly, the lower water absorption rollers 5 a and 5 b include a lower squeezing roller 24. The lower squeezing roller 24 is pressed against the water absorbing material 8 of the rotating lower water absorbing rollers 5a and 5b to compress and deform the water absorbing material 8, and the water contained therein is squeezed out for dehydration. A receiving plate 26 is provided at a portion where the upper water absorbing rollers 4a and 4b and the upper squeezing roller 22 are in contact with each other to prevent moisture from falling. The water squeezed out from the upper water absorption rollers 4a and 4b is caused to flow to the ends of the lower water absorption rollers 5a and 5b by the receiving plate 26, and is prevented from falling onto the lower water absorption rollers 5a and 5b. .
図１２は、駆動装置１３により上部の吸水ローラ４の押し付け圧力を変化させた場合に、フィルタ２の濾材１４から吸い出される水分量を測定した結果である。上部の吸水ローラ４の押し付け圧力を高めるとフィルタ２から吸い出される水分量が増加することがわかる。フィルタ２は、脱水装置１により連続的に脱水されると、脱水率は５０パーセント以上となる。ここに、脱水率は、式（１−Ｗ1／Ｗ0）で表され、Ｗ1は脱水後にフィルタに残存している水分量であり、Ｗ0はフィルタの飽和水分量である。 FIG. 12 shows the result of measuring the amount of moisture sucked out from the filter medium 14 of the filter 2 when the pressing pressure of the upper water absorbing roller 4 is changed by the driving device 13. It can be seen that the amount of water sucked out from the filter 2 increases when the pressing pressure of the upper water absorption roller 4 is increased. When the filter 2 is continuously dehydrated by the dehydrating apparatus 1, the dehydration rate becomes 50% or more. Here, the dehydration rate is expressed by the formula (1-W 1 / W 0 ), W 1 is the amount of water remaining in the filter after dehydration, and W 0 is the saturated water amount of the filter.
次に、脱水装置１の動作について、図１３を用いて説明する。図１３は、本実施形態におけるフィルタの脱水方法を示すフローチャートである。 Next, the operation of the dehydrating apparatus 1 will be described with reference to FIG. FIG. 13 is a flowchart showing a filter dewatering method according to this embodiment.
まず、コンベア３が、フィルタ２を脱水装置１に搬送する（Ｓ１）。次に、移動機構６が、上部の吸水ローラ４をフィルタ２に押し付ける（Ｓ２）。このとき、移動機構６は、上部の吸水ローラ４を、フィルタ２の濾材１４が変形するまで移動させ、これにより濾材１４内の水分２０を凝集させて、上部の吸水ローラ４と濾材１４間に水の通路を形成させる。 First, the conveyor 3 conveys the filter 2 to the dehydrator 1 (S1). Next, the moving mechanism 6 presses the upper water absorption roller 4 against the filter 2 (S2). At this time, the moving mechanism 6 moves the upper water absorption roller 4 until the filter medium 14 of the filter 2 is deformed, thereby agglomerating the moisture 20 in the filter medium 14, and between the upper water absorption roller 4 and the filter medium 14. Form a water passage.
そして、移動機構６が、上部の吸水ローラ４をフィルタ２から離隔する（Ｓ３）。このとき、移動機構６は、濾材１４の変形を戻しフィルタ２から離れるように上部の吸水ローラ４を移動させ、これにより濾材１４の変形が戻る際に上部及び下部の吸水ローラ４，５が接触している部分に水分量の少ない領域が形成されるため、形成された水の通路を通って毛細管現象により上部及び下部の吸水ローラ４，５へ濾材１４の水分を吸収する。 Then, the moving mechanism 6 separates the upper water absorption roller 4 from the filter 2 (S3). At this time, the moving mechanism 6 returns the deformation of the filter medium 14 and moves the upper water absorption roller 4 so as to move away from the filter 2, so that when the deformation of the filter medium 14 returns, the upper and lower water absorption rollers 4 and 5 come into contact with each other. Since a region with a small amount of water is formed in the portion where the water is passed, the water in the filter medium 14 is absorbed by the upper and lower water absorption rollers 4 and 5 through the formed water passage by capillary action.
そして、コンベア３が、フィルタ２を脱水装置１から外部へと搬送する（Ｓ４）。そして、移動機構６が、上部の吸水ローラ４を下部の吸水ローラ５に押し当てるように移動させ、上部及び下部の吸水ローラ４，５に含まれる水分を絞り出して脱水作業を行い（Ｓ５）、作業が終了する。なお、次に脱水するフィルタ２がある場合には、また、スタートに戻る。 Then, the conveyor 3 conveys the filter 2 from the dehydrator 1 to the outside (S4). Then, the moving mechanism 6 moves the upper water absorbing roller 4 so as to press against the lower water absorbing roller 5, squeezes out the water contained in the upper and lower water absorbing rollers 4 and 5, and performs a dehydrating operation (S5). The work is finished. When there is a filter 2 to be dehydrated next time, the process returns to the start.
本実施形態の脱水装置１においては、上部及び下部の吸水ローラ４，５と濾材１４で発生する毛細管現象を利用して、フィルタ２の脱水を行う。これにより、洗浄後のフィルタ２の濾材１４内部に含まれる水分を短時間に効率よく取り除くことができる。また、一方向Ｂに複数並んだ下部の吸水ローラ５を回転させて、フィルタ２を搬送させることで、連続的にフィルタ２の脱水作業を行うことができる。また、吸水ローラ４，５に切り込みが形成されているので、多様な形状のフィルタ２にも対応することができる。 In the dehydrating apparatus 1 according to the present embodiment, the filter 2 is dehydrated by utilizing the capillary phenomenon generated in the upper and lower water absorbing rollers 4 and 5 and the filter medium 14. Thereby, the water | moisture content contained in the filter medium 14 of the filter 2 after washing | cleaning can be removed efficiently in a short time. In addition, the lower water absorption rollers 5 arranged in the same direction B are rotated to convey the filter 2, whereby the filter 2 can be continuously dehydrated. Further, since the water absorption rollers 4 and 5 are formed with cuts, it is possible to deal with various shapes of the filter 2.
