Description
本發明是有關於一種固液分離用的濾袋，且特別是有關於一種製造快速，濾袋良率高且不易破損的碟盤式濾袋的製造方法及其製造裝置。The present invention relates to a filter bag for solid-liquid separation, and more particularly to a method for manufacturing a disk filter bag which is fast to manufacture, has a high yield of a filter bag, and is not easily broken, and a manufacturing apparatus therefor.
以薄膜過濾裝置進行固液分離的技術，已被廣泛的運用在污水回收處理上，其中，將薄膜完全浸入污水處理槽內，並在槽底增加曝氣供氧的浸泡式作法，因為是採用負壓將濾液吸入產水側，所以可降低污水通過薄膜時的能源損耗，且因薄膜係安裝在槽體內，故亦較不佔空間。The technology of solid-liquid separation by membrane filtration device has been widely used in sewage treatment, in which the membrane is completely immersed in the sewage treatment tank, and the immersion method of aeration and oxygen supply is added at the bottom of the tank because it is adopted. The negative pressure draws the filtrate into the water producing side, so that the energy loss when the sewage passes through the film can be reduced, and since the film is installed in the tank, it does not occupy a space.
目前已知的浸泡式過濾裝置，較常見的有中空管、中空纖維薄膜(Hollow fiber membrane)、板框式薄膜(Flat sheet membrane)等型式，其特點為單位體積內具有較大的截污面積，因此產水側可獲得理想的濾液與過濾效果。另一方面，為了避免處理槽內因濃度極化現象(Concentration Polarization)與薄膜阻塞(Membrane Fouling)，造成濾液流速的衰減，雖然已在槽底增加曝氣擾動，但防污堵的效果仍不彰，較有效率的方式是對薄膜(管)進行逆洗程序，使積附在濾膜外表的濾餅產生脫離，上述的中空管與中空纖維薄膜由於孔徑相當細微，因此並無法施以逆洗程序，而板框式薄膜雖宣稱能以濾液由產水側沖出濾餅，但受限於板框形體的限制，濾液反向沖除至板框各個側邊的壓力勢必不相同，所以實際上並不能達到逆洗的效果。Currently known immersion filter devices are more commonly used in the form of hollow tubes, Hollow fiber membranes, and flat sheet membranes, which are characterized by large dirt interception per unit volume. The area, so the water side can achieve the desired filtrate and filtration effect. On the other hand, in order to avoid the concentration fluctuation of the filtrate due to Concentration Polarization and Membrane Fouling, although the aeration disturbance has been increased at the bottom of the tank, the anti-fouling effect is still not Zhang, a more efficient way is to carry out a backwashing process on the film (tube) to remove the filter cake attached to the outer surface of the filter. The above hollow tube and hollow fiber film are not fine enough to be applied. Backwashing process, while the plate and frame type film claims to be able to flush the filter cake out of the water producing side by the filtrate, but it is limited by the limitation of the plate frame shape, and the pressure of the filtrate reversely flushed to each side of the plate frame is different. Therefore, the effect of backwashing is not actually achieved.
有鑑於此，本案申請人已開發出一種碟盤式的濾膜，其是在兩個呈圓形的薄膜之間夾設有一網孔狀的支撐網，而支撐網在外緣是以超音波黏合方式與前述薄膜相積合，且薄膜與支撐網中央同心穿設有一產水孔，如此，即形成三層狀的囊袋濾膜結構，此濾膜的產水孔是套穿在一表面具有多數通孔的產水管上，在另外用一導水盤組於兩側夾壓固定，相關的專利案已可見諸於公告第I295589號、第I312767號、第1303579號等專利案。由於濾膜為圓盤型，且產水孔設置於盤面的中央，因此進行逆洗程序時，濾液對薄膜的反向推擠壓力皆為一致，因此可獲得良好的逆洗效果，且濾膜不須要在側邊或外緣以厚框進行組固，因此整體重量輕、厚度薄，在相同的空間下，其濾膜可疊組的數量更高，相對有效的截污面積更大。In view of this, the applicant of the present application has developed a disc-type filter membrane in which a mesh-shaped support net is sandwiched between two circular films, and the support net is ultrasonically bonded at the outer edge. The method is integrated with the film, and the film and the center of the support net are concentrically pierced with a water producing hole, so that a three-layered bag filter membrane structure is formed, and the water producing hole of the filter film is sleeved on a surface. Most of the through-hole water-producing pipes are additionally clamped and fixed on both sides by a water-conducting disc group. The related patent cases can be seen in the patent cases such as Announcement No. I295589, No. I312767, No. 1303579. Since the filter membrane is of a disc type and the product water hole is disposed at the center of the disc surface, when the backwashing process is performed, the reverse pressing force of the filtrate on the film is uniform, so that a good backwashing effect can be obtained, and the filter is obtained. The film does not need to be framed by a thick frame at the side or the outer edge, so the overall weight is light and the thickness is thin. In the same space, the number of filter layers that can be stacked is higher, and the relatively effective intercepting area is larger.
雖然，上述的碟盤式濾膜結構具有可逆洗、截污能力高的諸多優點，但在實際的製造上，卻有其待改進與解決之處；即，以往的製法是先裁切成預定尺寸的支撐網與薄膜，然後將三者放入一模具內疊合，接著，再利用超音波熔接方式，對三者的邊緣施以超音波黏合密接，同時，利用切刀頭在中央裁切出該產水孔，但對於濾膜的外徑尺寸較大，要一次性地對於濾膜的邊緣施以超音波黏合勢必不可能，通常是以分段的迴轉式超音波技術來予以接合(一般是將外緣分成三個120度的扇形區塊來加工)，而基於邊緣水密性要求要高的前提下，濾膜在外緣將不可避免地有局部重覆黏合的超音波接緣，此重疊的接緣會因熔接時間過久，使得濾膜表面產生燙傷、變型，甚至有肉眼無法辨識的損害縫隙，使得產品的不良率提高，且對於防漏的水密性品管上，亦衍生出後續的困擾，再者，這種分段接合外緣的方式，在產速上過於緩慢，需要大量的人力來操作，並不符合經濟效益。Although the above-mentioned disc filter membrane structure has many advantages of reversible washing and high dirt intercepting ability, in actual manufacturing, there is a need to be improved and solved; that is, the conventional manufacturing method is first cut into a predetermined one. The size of the support mesh and the film, then put the three into a mold, and then use the ultrasonic welding method to apply ultrasonic bonding to the edges of the three, and at the same time, use the cutting head to cut in the center The water hole is produced, but for the outer diameter of the filter membrane, it is impossible to apply ultrasonic bonding to the edge of the filter film at one time, usually by segmented rotary ultrasonic technology ( Generally, the outer edge is divided into three 120-degree fan-shaped blocks for processing), and on the premise that the edge water-tightness requirement is high, the filter film will inevitably have a partially overlapping ultrasonic ultrasonic wave on the outer edge. Overlapped joints may cause burns, deformations, and even damage to the surface of the filter film due to excessive welding time, which may result in an increase in the defective rate of the product, and also on the watertight quality control tube for leak prevention. Rear The troubled addition, this segment engages the outer edge of the way, too slow on the production speed, requires a lot of manpower to operate, it is not cost-effective.
此外，因為是採用分段迴轉加工黏合，中央的產水孔在經過切刀頭沖壓後，會使得薄膜與支撐網產生暫時性的密壓銜接，影響產水時濾液的流通行進，必須要另外以人力掰開，亦不方便。In addition, because the segmented rotary processing is used for bonding, the central water production hole is pressed by the cutter head, which causes the film and the support net to temporarily bond tightly, which affects the circulation of the filtrate during the production of water, and must be additionally It is also inconvenient to open it with human resources.

操作時，將兩層薄膜基材13分別夾設在該導水網基材14的頂、底面，以構成三層狀的一積層材料，並利用各該傳動輪11之傳動，將前述三者組成的積層材料帶送經過該熱壓單元20的熱壓輥輪24下方。接著，啟動氣壓缸21、傳動組22與加熱組23，該氣壓缸21可驅使熱壓輥輪24下移而接觸積層材料，並與該加熱組23形成共同夾壓積層材料，然後，積層材料在傳動組22及熱壓輥輪24的牽引下，加熱組23會對於積層材料施以高頻振盪，同時，該熱壓輥輪24開始同步旋轉，再利用熱壓輥輪24上的凹紋241對兩薄膜基材13與導水網基材14進行超音波之熱壓處理，以成型出一碟盤狀且中空的濾袋100半成品。上述進行超音波熔接時，該熱壓滾輪24的凹紋241外緣係具有細微的切緣(圖未示)，因此可在熱壓輥輪24輥壓積層材料時，對熔接緣110的最外周圈形成切斷效果，使濾袋100半成品可自積層材料上分離。請參照第4圖與第5圖，最後，再利用該沖孔單元30對該濾袋100半成品中央部位施予沖孔處理，使濾袋中央形成有一產水孔120(如第4圖所示)，即可完成。In operation, the two film substrates 13 are respectively placed on the top and bottom surfaces of the water-conducting mesh substrate 14 to form a three-layered laminated material, and the transmission of each of the transmission wheels 11 is used to form the three components. The laminated material is conveyed under the hot pressing roller 24 of the hot pressing unit 20. Next, the pneumatic cylinder 21, the transmission group 22 and the heating group 23 are activated. The pneumatic cylinder 21 can drive the hot pressing roller 24 to move down to contact the laminated material, and form a common laminated material with the heating group 23, and then laminate the material. Under the traction of the transmission group 22 and the hot-pressing roller 24, the heating group 23 applies high-frequency oscillation to the laminated material, and at the same time, the hot-pressing roller 24 starts synchronous rotation, and then uses the concave pattern on the hot-pressing roller 24. 241 pairs the two film substrates 13 and the water-conducting net substrate 14 by ultrasonic hot pressing treatment to form a disk-shaped and hollow filter bag 100 semi-finished product. When the ultrasonic welding is performed as described above, the outer edge of the concave line 241 of the hot pressing roller 24 has a fine cutting edge (not shown), so that the most suitable welding edge 110 can be applied when the hot pressing roller 24 rolls the laminated material. The outer circumference forms a cutting effect, so that the semi-finished product of the filter bag 100 can be separated from the laminated material. Referring to FIG. 4 and FIG. 5, finally, the punching unit 30 is used to apply a punching treatment to the central portion of the semi-finished product of the filter bag 100, so that a water producing hole 120 is formed in the center of the filter bag (as shown in FIG. 4). ), you can complete.
參照第6圖，本發明碟盤式濾袋的製造方法的第二實施例，包含以下步驟：Referring to Figure 6, a second embodiment of the method of manufacturing a disk filter bag of the present invention comprises the following steps:
步驟(A)：製備具有透氣性的兩薄膜基材、一導水網基材及兩保護膜，前述保護膜是以非熱可塑性的薄膜材料製成，例如紙材、離形紙(release paper)、木纖紙...等。Step (A): preparing a gas-permeable two-film substrate, a water-conducting mesh substrate and two protective films, the protective film being made of a non-thermoplastic film material, such as paper, release paper , wood fiber paper, etc.
步驟(B)：將前述薄膜基材分別貼設在該導水網基材的頂、底面，並將前述保護膜分別安置於兩薄膜基材的外側，以構成五層狀的一積層材料。Step (B): The film substrate is respectively attached to the top and bottom surfaces of the water-conducting mesh substrate, and the protective film is respectively disposed on the outer sides of the two film substrates to form a five-layer laminated material.
步驟(C)：將該積層材料以一可保持穩定張力的機具進行連續輸送，並在其輸送路徑上對該積層材料以一熱壓單元進行熱壓積合，該熱壓單元是在該積層材料的移動路徑上，以點接觸方式對其施以熱輥壓，藉以在該積層材料上形成一個使前述材料相互密合且呈圓形的熔接緣110，以及兩道鋸狀的抗拉定位條130(如第3圖所示)，且促使該積層材料上形成有一碟盤狀且中空的濾袋半成品。另外，前述進行熱壓的同時，是同步將濾袋半成品予以切斷。Step (C): continuously conveying the laminated material in a machine capable of maintaining a stable tension, and thermally laminating the laminated material in a conveying path by a hot pressing unit, wherein the hot pressing unit is in the laminated layer The moving path of the material is subjected to hot rolling in a point contact manner, thereby forming a welded edge 110 on the laminated material which makes the materials adhere to each other and has a circular shape, and two saw-like tensile positions. Strip 130 (as shown in Figure 3), and causes the laminated material to have a disk-shaped and hollow filter bag semi-finished product. In addition, the above-described hot pressing is performed to simultaneously cut the filter bag blank.
步驟(D)：將濾袋半成品兩側面的保護膜撕除，由於濾袋半成品兩側面的保護膜為非熱可塑性材料，因此，經熱壓積合後，不會與薄膜基材產生熔接，使操作者可以輕易地外將濾袋半成品外側面上的保護膜予以撕除。Step (D): tearing off the protective film on both sides of the semi-finished product of the filter bag, since the protective film on both sides of the semi-finished product of the filter bag is a non-thermoplastic material, after being hot-pressed, the film substrate is not welded. The operator can easily tear off the protective film on the outer side of the semi-finished product of the filter bag.
步驟(E)：將經過輥壓後的濾袋半成品經過一沖孔處理，使濾袋半成品的中心被裁出一產水孔，以構成一碟盤式濾袋成品。Step (E): the punched semi-finished product of the filter bag is subjected to a punching process, so that the center of the semi-finished product of the filter bag is cut out to produce a water hole to form a finished product of the disc filter bag.
如上所述，相較於以往碟盤濾袋製法的使用問題，本發明之碟盤式濾袋的製造方法及其製造裝置，具有以下功效及優點，如下列整理：As described above, the method for manufacturing the disc filter bag of the present invention and the manufacturing apparatus thereof have the following effects and advantages as compared with the use of the conventional disc filter bag manufacturing method, such as the following finishing:
一、利用點接觸方式使得熱壓輥輪24熔接一圈就可成型出碟盤狀的濾袋，製造快速，且機械一貫化作業，作業快速、可降低製造成本。1. By using the point contact method, the hot pressing roller 24 can be welded to form a disk-shaped filter bag, which is fast in manufacturing and mechanically consistent, quick in operation and can reduce manufacturing cost.
二、相對於以往濾袋採用的面接觸的分段超音波熔接，本發明的積層材料在單位時間內，係實施採用點接觸熔接作業，其功率耗損低，可節省成源。Second, compared with the segmental ultrasonic welding of the surface contact used in the conventional filter bag, the laminated material of the present invention adopts the point contact welding operation in a unit time, and the power consumption is low, and the source can be saved.
三、連續式的點接觸熔接方式，無重複熔接部位，因此濾袋不易破損，也無熔接空隙產生之問題，故品質佳且良率高，可大幅降低廢料之產生。Third, the continuous point contact welding method, no repeated welding parts, so the filter bag is not easy to break, there is no problem of welding gap, so the quality is good and the yield is high, which can greatly reduce the generation of waste.
四、利用沖孔單元直接貫穿濾袋，使得薄膜基材與導水網基材之間不致相黏接，所以也無需另以人力掰開。4. The punching unit is directly penetrated through the filter bag, so that the film substrate and the water-conducting net substrate are not bonded to each other, so there is no need to manually open the filter.
值得一提的是，第二實施例所製造出的碟盤式濾袋，藉以熱壓輥輪24之側壓紋242之同步壓合處理，以保持積層材料表面適當張力，將使該積層材料保持更穩定地被機具連續輸送，不但可強化碟盤濾袋的製造品質，也可加速製造作業。另外，第7圖中五層狀的積層材料，其保護膜15的設置，於加工當中，以維持薄膜基材13表面的平整性，可避免薄膜基材13因表面皺折而經超音波壓合處理後無法完整地密接，或是受到油污的沾污，如此，可維持濾袋100的品質。It is worth mentioning that the disc filter bag manufactured by the second embodiment is subjected to the synchronous pressing treatment of the side embossing 242 of the hot pressing roller 24 to maintain the proper tension of the surface of the laminated material, which will make the laminated material Continuously transported by the implement more stably, not only can enhance the manufacturing quality of the disc filter bag, but also accelerate the manufacturing operation. Further, in the five-layered laminated material in Fig. 7, the protective film 15 is disposed during processing to maintain the flatness of the surface of the film substrate 13, and the film substrate 13 can be prevented from being ultrasonically pressed due to surface wrinkles. After the treatment, it cannot be completely adhered or contaminated by oil, so that the quality of the filter bag 100 can be maintained.
惟以上所述者，僅為本發明之數個實施例而已，當不能以此限定本發明實施之範圍，即大凡依本發明申請專利範圍及發明說明內容所作之簡單的等效變化與修飾，皆應仍屬本發明專利涵蓋之範圍內。However, the above is only a few embodiments of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All should remain within the scope of the invention patent.
