And cut off, as a result of J 153942.doc 201143876, the end face of the module is formed. The end face of the module is formed with an opening communicating with the inside of the hollow fiber membrane. The film module is manufactured by using the head cover member, whereby the dimensional stability of the film module as a finished product becomes high. [Prior Art] [Patent Document 1] [Patent Document 1] Japanese Patent Laid-Open Publication No. 2007-503298 [Draft of the Invention] [Problems to be Solved by the Invention] In recent years, in the manufacture of brewed beverages such as beer or wine In order to filter the diatomaceous earth, in recent years, from the viewpoint of environmental protection, the membrane separation method which does not use diatomaceous earth has been used, so the membrane module market used to replace Shishizao soil has expanded. A filter cartridge type membrane module is used in this field, and the wide-tube membrane module is subjected to filtration under high pressure (carbon dioxide gas pressure) and inserted into a stainless steel casing. In the manufacturing steps of the brewed beverage described above, the number is passed. After the filtration step of C, a chemical cleaning step of about 8 〇 C is carried out, which is used to remove the fouling material deposited on the membrane surface due to over-twisting to restore the filtration performance. That is, during a series of filtration operations, the hollow fiber membrane module is repeatedly exposed to low temperature and high temperature environments. When peeling occurs between the inner surface of the previous head cover member in contact with the sealing material and the sealing material by performing the above-described low-temperature filtration step and the cleaning step of the temperature, the peeling tends to grow, and as a result, sometimes This will result in a decrease in the quality of the membrane module. The present invention has been made in view of the above problems, and an object of the present invention is to provide a method for manufacturing a head cover member, a film module and a film module, 153942.doc 201143876, which is particularly suitable for beer fermentation broth In the filtration of the brewed beverage, in the harsh operating environment in which the low-temperature filtration step and the high-temperature cleaning step are repeated, the peeling of the inner surface in contact with the sealing material and the filling to the inner <sealing material can be suppressed. Produced or grown to help improve the quality of the membrane module. [Technical means for solving the problem] The present invention is a bottomed cylindrical head member which is attached to an end portion of a hollow fiber membrane bundle and which is internally filled and solidified with a sealing material, thereby being fixed to the hollow fiber membrane bundle, The bottomed cylindrical head cover member is characterized by comprising: an inlet-side tubular portion 'which is disposed on an inlet side of the hollow fiber membrane bundle; and an end-side tubular portion having an inner diameter smaller than an inner diameter of the inlet-side tubular portion, And disposed on the end side of the inlet-side tubular portion; and a step is formed between the inner surface of the inlet-side tubular portion and the inner surface of the end-side tubular portion, and on the inlet-side tubular portion and the end portion side The inner surface of the tube portion from the Π丨T to the inner surface is formed with an annular groove around the axis of the head 盍 member. According to the present invention, even if the peeling occurs on the inlet side of the head 盍 member, the step is formed on the inner surface of the inlet side cylindrical portion, so that the step is formed by the inner surface of the (four) portion. The peeling is prevented from spreading from the side of the inlet side tube side toward the end side of the tube side of the tube, and therefore, the stripping of the stalks p ^ ^ to the merchant's sign 'growth again to suppression. Moreover, due to the denseness of the inside of the head-shaving member, /L, <, the shape of the king-shaped groove is solid

Therefore, the head cover member is fitted to the seal U and the contact faces of the Baotian^ are concave-convex with each other. And the cattle are solidly combined to be effective for inhibition. As a result of the growth of the seat, it is advantageous for the product such as the diaphragm module. Preferably, the end side tubular portion of the head cover member includes: a cylindrical main body 153942.doc 201143876 body, And integrally formed on the bottom of the main body portion. Further, it is preferable that the groove includes a shallow groove formed in the inlet-side tubular portion and a deep groove deeper in the shallower groove formed in the end-side tubular portion, in a case where the sealing material is filled into the inside of the head cover member, For example, an introduction port of a sealing material is formed on the end side of the head cover member, and the sealing material is filled through the introduction port. The deeper the groove formed on the inner surface of the head cover member, the stronger the bond between the sealing material and the head cover member, thereby suppressing the peeling. However, for the method of filling the sealing material from the end side of the head cover member Compared with the end side tubular portion, the sealing material is more difficult to enter into the inlet side tubular portion. Therefore, if the groove of the inlet side tubular portion is made too deep, the sealing material is fully ingested, so that it exists in the sealing material and the head cover member. In the case where the gap w is 3, the sealing material can easily enter the end-side tubular portion as compared with the inlet-side tubular portion. Therefore, even if the depth of the groove is actively deepened, the sealing material can be sufficiently entered. That is, according to the above configuration, when the sealing material is filled from the end side of the head cover member, the (four) material can be surely filled, and the combination of the head cover member and the sealing material can be easily realized even at a high pressure (for example, Carbon dioxide gas (four) force) and the extent of the temperature change in the over-the-step and cleaning steps is super-secret. c is very harsh (4) Under operating conditions, it is also effective for the growth of _ _ _. Winding cover: In the inner surface of the end side tubular portion of the present invention, an annular convex portion having an axis of 冓: is formed. Filling the inside of the head cover member (4) The convex portion of the inner surface of the gap u between the hollow fiber membrane bundle and the head cover member is concealed to the inside of the head shame member. The sealing material will be in the process of curing. 153942.doc 201143876 Shrinking 'But in this case, it will shrink in such a manner as to clamp the convex portion, so the second: = peeling during the sealing of the material. As a result, the quality of the material curing module is effective. Further, the membrane module of the present invention is characterized in that: the tubular head portion formed by the member, including the plug: == stop - the multi-dimensional membrane bundle fixes the hollow fiber membrane bundle to According to the present invention, the head surface seal portion and the module end opening the inside of the hollow fiber membrane are peeled off at the inlet side of the head cover portion, and are formed between the inner surfaces of the inner tube portion of the end portion of the inner surface The stepped portion propagates the step to prevent peeling from the inlet side cylindrical portion toward the end portion side. In addition, since the contact faces of the head cover portion and the sealing material are in good quality = firmly bonded together, Preferably, the membrane module 2' is preferably the membrane module further comprising a tubular protective member, the "protective member" encloses the hollow fiber membrane bundle in an annular shape, and is sealed together with the membrane bundle The portion is fixed to the head cover portion, and has a plurality of through holes and a linear protruding portion that protrudes in the axial direction from the end portion fixed to the side of the head cover portion, and is protected by the protective member. a bundle of hollow fiber membranes to protect the bundle of hollow fiber membranes; In addition, at the end of the protective member, a linear protruding portion is provided so as to protrude toward the axis of the ::: member, and the ridge is protected by the flat circumference without the protruding portion. When the end portion of the member is 153942.doc 201143876, peeling is generated right at the end portion, the peeling is likely to propagate in the circumferential direction, and the peeling is easy to grow. However, according to the above configuration, the protruding portion formed at the end portion of the protective member becomes an obstacle. Further, the peeling is prevented from propagating in the circumferential direction, and therefore, it is effective for suppressing the growth of peeling. Further, it is preferable that the protective member has a mesh shape and a plurality of meshes forming the through holes are formed in the protective member. The end portions are respectively protruded from a plurality of meshes which are connected in a ring shape, and the plurality of protruding protrusions corresponding to the plurality of meshes are disposed at substantially equal intervals and arranged in the circumferential direction to effectively prevent peeling.

Specifically, S' includes: ") a step of arranging and arranging a specific number of hollow fiber membranes in a manner substantially parallel to the length direction; b) in a manner to achieve a specific length The step of cutting the hollow fiber membrane 7a neatly, and the step of clogging the hollow portion of the hollow fiber membrane 7a, and appropriately performing the opening of the pores of the end portion of the hollow fiber membrane 7& In the method of adjusting the degree of opening, for example, a method of forming a state in which a glycerin aqueous solution is impregnated into a pore and then drying is performed, and glycerin is contained in the pores. The above a) to d The unit steps can be performed in the order described, or can be appropriately changed. Then, the assembly steps of the module precursor elements are performed (step Μ). Specifically, the bundle of hollow fiber membrane bundles 7 is Into the protective member 1 1. Following the 153942.doc 201143876 and 'dividing the hollow fiber membrane bundle 7 equally, inserting the cross plate 13 into the exposed portion of the self-protecting member 11' installs the head cover member 9 in this state. The assembly of the module precursor elements is performed at both ends of the hollow fiber membrane bundle 7. Then, the step of filling the liquid sealing material S into the inside of the head cover member 9 is performed (step S3). The filling method includes a centrifugal casting method in which the sealing material s is filled by centrifugal force, a static casting method in which the sealing material s is filled by gravity, and the like. The centrifugal casting method and the standing pouring method are mainly described. The centrifugal casting method is used for the centrifugal casting machine of the clamp of the centrifugal box. The structural system in which the module precursor elements are assembled is mounted horizontally on the centrifugal 'box, with the vertical axis as the rotation axis. Rotating on a horizontal plane, centrifugal force acts on the head cover member 9 by the rotation of the centrifugal box, and the sealing material 8 is filled into the inside of the head cover member 9 by the centrifugal force. For the filling method of the centrifugal force, for example, according to the length of the hollow fiber membrane bundle 7, two methods can be considered. One method is to simultaneously cast the two ends from the four casting methods, and the other method is on each side. In the case of two centrifugation methods, for example, '# every two sides are separated from u; when casting, one end of the object to be placed is placed in the centrifugal direction, and the other end is placed in the inner side of the centrifugation and direction. The liquid material is transferred to the side of the centrifugal direction member 9 by the centrifugal force, and the sealing material S is filled into the inside via the bottom portion 2 of the head cover member 9. The introduction port is additionally placed on the inside. The system is equipped with a hollow fiber J53942.doc • 19- 201143876 with a head cover member 9 configured to be erected in the vertical direction. One end of the hollow fiber membrane bundle 7 which becomes the next object is on the lower side, and the other end is on the upper side. The liquid sealing material S is filled into the inside of the lower head cover member 9 via the introduction port 9a of the bottom portion 9b. Here, the sealing material S is introduced by a head difference, a pump, or the like, and is filled into the inside of the head cover member 9 without a gap. Thereafter, after the fluidity of the sealing material S disappears, the upper and lower reverse sealing material $ is filled in the same manner as described above to the inside of the lower head cover member 9. The filling of the sealing material s in the above step S3 is performed while the sealing material s is in a liquid state. Further, with respect to the filled sealing material S, the reaction proceeds with time, and the fluidity of the sealing material S gradually disappears to become a solid state. Then, the step of solidifying the sealing material s filled in the inside of the head cover member 9 to form the sealing portion 15 is performed (step S4). After the sealing material S is solidified to form the sealing portion 15, the curing is performed at a specific temperature T1 (for example, 5 〇. 〇 heating for a specific time (step S5). Then, the temperature is higher than the high temperature T2 of the butyl enthalpy (for example, 9 〇 β 〇 heating specific The curing is further carried out in time (step S6). The module precursor 5 is completed by the above operation. Then, the following steps are performed, that is, one portion of the end portion of the hollow fiber membrane and the bottom portion 9b of the head cover member 9 And a part of the sealing portion 15 is cut "to form a module end face 6 that opens the inside of the plurality of hollow fiber membranes 7a (step S7), thereby completing the cartridge module i. Then the 'head cover member 9 and the cartridge module The effect of the r is explained. When the module precursor 5 is manufactured, the sealing material S is filled with the gap between the inside of the head cover member 9 (see Figs. 5 and 6), and the seal 153942.doc - 20· 201143876 Material S solidified 'The inner surface of the hollow fiber membrane bundle 7, the cross plate", the protective member", the head cover member 9 is then joined (bonded). For the head cover member 9, the inlet side tubular portion 21 Inner diameter is larger than Duanwu The inner diameter rl of the tubular portion 23 is provided with a step St between the inner surfaces of the inlet-side tubular portion 21 and the end-side tubular portion 23. During the curing of the sealing material S, the sealing material 8 may slightly occur. By the heat shrinkage, it is assumed that even if the human π side tubular portion 21 is peeled off at the contact surface with the sealing material S, the peeling from the inlet side tubular portion toward the end side tubular portion 23 is spread. Also, the step sm is stopped, so that the growth of the peeling is suppressed. Further, the inner surface of the head cover member 9 is formed with deep grooves 23a or shallow grooves 21a, 23b, and the sealing material 8 enters the deep groove 23 & or the shallow groove 21 & Therefore, the contact surfaces of the head cover member 9 and the sealing material s are embedded in a concavo-convex shape, and the cows are solidly bonded (bonded), thereby being effective for suppressing the growth of peeling, and the effect of peeling off (not The effect of causing a leak is large, for example, heat or pressure or radiation treatment when the gas is destroyed. As a result, the quality of the cartridge module 1 can be improved. Further, the entrance of the head cover member 9 A shallow groove 2ia is formed at the side tubular portion 21 at the end In addition to the shallow groove 21a formed in the side tube portion 23, a deep groove 23a is formed, for example, the deeper the groove formed on the inner surface of the head cover member 9, the deeper the sealing material S enters and solidifies. Therefore, the more the depth of the groove is iced, the stronger the above-mentioned sealing material s is bonded to the head cover member 9, thereby being advantageous in suppressing peeling. However, for the method of filling the sealing material S from the outside of the bottom of the head cover member 9 The sealing material S is more difficult to enter the inlet-side tubular portion 2 than the end-side tubular portion 23, and therefore, if the groove of the inlet-side tubular portion 21 is 153942.doc • 21 · 201143876 is too deep, the sealing material 8 It is impossible to completely enter the inlet side cylindrical portion 21, so that there is a possibility that a gap is generated between the sealing material s and the head cover member 9. On the other hand, the sealing material s easily enters the end side tubular portion 23 as compared with the inlet side tubular portion 2i. Therefore, even if the depth of the groove is actively deepened, the sealing material s can be sufficiently introduced. That is, according to the cover member 9, when the sealing material 8 is filled from the bottom portion 9b side, the sealing material S' can be surely filled and the firm bonding between the head cover member 9 and the sealing material S can be easily achieved. Peeling or inhibiting the growth of peeling is effective. Further, in the end portion side tubular portion 23 of the present embodiment, the shallow groove 23b is formed in the outer side of the deep groove 23a. However, only the deep groove 23a may be formed without forming the shallow groove 23b. Further, on the inner surface of the end portion side tubular portion 23 of the head cover member 9, an annular second convex portion 23c and a second convex portion 23d which surround the axis L of the head cover member 9 are formed. After the sealing material S is filled into the inside of the head cover member 9, the i-th convex portion 23c and the second convex portion 23d are covered. As described above, the sealing material s undergoes heat shrinkage during the curing process, but in this case, the sealing material s covering the convex portion Μcd shrinks by sandwiching the convex portions 23c and 23 (1). It is possible to prevent the peeling of the sealing material s during the curing process, and it is effective in suppressing the growth of the peeling and improving the quality of the cartridge module 1. The filter module 1 of the present embodiment uses the above-described head cover member 9 Since the head cover portion 1a is formed, the generation and spread of the peeling when the sealing portion 15 is formed by curing the sealing material s are suppressed, and high quality can be expected. Further, the module 1 includes an annular shape. The hollow fiber membrane bundle 7 surrounds the cylindrical protective member u of 153942.doc -22- 201143876, and therefore, the hollow fiber membrane bundle 7 is uniformly maintained by the protective member ,, and the hollow fiber membrane bundle 7 is protected. In addition, the protective member 11 is formed with a linear (stripe) protruding portion i lc that is fixed to the both end portions of the head cover portion 1 & No protrusion 1 lc When the end portion of the protective member is formed on the flat circumference, if peeling occurs at the end portion, the peeling tends to propagate in the circumferential direction, and the peeling tends to grow. However, according to the protective member of the present embodiment, the protruding portion 11c becomes an obstacle and prevents peeling from propagating in the circumferential direction, so it is effective for suppressing the growth of peeling. Further, peeling can be caused by the presence or absence of appearance before and after curing in the step of manufacturing the cartridge module 1. Further, the effect of the protruding portion 丨丨c is confirmed. Further, even when the membrane filtration is performed using the cartridge module 1, for example, peeling occurs between the head cover portion 1a and the sealing portion 15 due to physical cleaning or chemical cleaning. However, in the present embodiment, since the head cover portion 1a and the sealing portion 15 are firmly joined (bonded), the occurrence of peeling can be effectively prevented, and even if peeling occurs, it is effective. The growth of the peeling is suppressed. Further, according to the manufacturing method of the cartridge module (membrane module) 1, in the process of forming the sealing portion 15, even in the head cover The peeling of the inlet side of the member 9 also prevents the peeling from the side of the inlet side tubular portion 2 by the step st formed between the inner surface of the inlet side cylindrical portion 21 and the inner surface of the end side tubular portion 23 The end side tubular portion 23 is propagated. And 'the sealing material S filled into the inner portion of the head cover member 9 enters into the annular shallow groove 21a, 23b or the deep groove 23a, and is solidified, therefore, 153942.doc -23-201143876 The contact faces of the head cover member 9 and the sealing material 8 are fitted in a concavo-convex shape and firmly adhered (bonded), thereby being effective for suppressing generation or growth of peeling. As a result, a high-quality filter cartridge module can be manufactured. 1 ° The filter cartridge module (membrane module) obtained by the above-described production method, in particular, in the manufacture of the above-mentioned brewed beverage, even in the case of repeatedly performing high pressure (carbon dioxide gas pressure) and several ° C (low temperature) filtration steps and In the harsh operating environment of the 7crc (high temperature) cleaning step, no peeling occurs between the inner surface in contact with the sealing material s and the sealing material S filled in the inner portion, so that the raw liquid leaks toward the transition side, and the ground can be stably get on Filter.

At the end of the hollow fiber membrane, at this time, the cross plate is disposed such that the hollow fiber membrane is evenly distributed to each of the four regions 10 (Examples 1 to 8), and the hollow fiber bundle is bundled. After the two end portions are inserted into the head cover member, they are placed on the gantry, and the head cover members at both ends are fixed to the frame. Thereafter, the gantry is mounted on the centrifugal box, and the two-liquid mixing is performed by centrifugal casting.

In the same manner as in the ninth embodiment, when the leak inspection was performed every 100 cycles, there was no leakage until the end of 1000 cycles. Then, the hollow fiber membrane module was taken out from the outer casing, and when the head cover portion was observed, a slight gap (the peeled portion) was observed at the interface of the entrance portion of the inlet-side tubular portion of the head cover member. The peeling portion ends at the step portion. It is presumed that the peeling is generated starting from the portion of the bubble which is retained in the corner groove of the inlet-side tubular portion, and proceeds from the inlet end of the inlet-side tubular portion to the step portion. Further, it is changed to a step of introducing cooling water to 5 of its pure water within 2 hours and a step of introducing pure water heated to 4 ° C for 2 hours, except for 'with Example 9' When the thermal cycle test is performed in the same manner, there is no leakage at all. Further, when the head cover portion was observed, there was no change compared with that before the hot and cold cycle test, and no peeling was observed. (Comparative Example 3) A film module was produced in the same manner as in Comparative Example 2. At the stage after the manufacture of the film module, no peeling was found at all. However, air bubbles remain in the corner grooves provided in the inlet side cylindrical portion. The hot and cold cycle test was carried out in the same manner as in Example 9 except that the above film module was used.

Then, the hollow fiber membrane module is taken out from the outer casing, and the head cover portion is subjected to -32-153942.doc

S 201143876 When observed, the gap (the peeled portion) was continuously observed from the joint interface of the inlet side tubular portion of the head cover member to the cut end surface of the end side tubular portion. It is presumed that the peeling is generated from the portion of the bubble which is retained in the angular groove provided in the inlet-side tubular portion, and proceeds from the inlet end of the inlet-side tubular portion to the cut end face. Also, 'change to a step of cooling to 5 of its pure water within 2 hours and repeating the step of heating to 4 (r pure water in 2 hours), in addition to the example 9 In the same hot and cold cycle test, there is no leakage until after one cycle. 'But after 6 cycles, a leak occurs. As mentioned above, for pure water that will be cooled to 5〇c within 2 hours. The step is to repeat the process of heating to 8 〇 ° C of pure water within 2 hours. After repeating 2 循环 cycles, the leak-free membrane module will not leak even if it repeats 1 cycle. On the other hand, as shown in Comparative Example 3, no peeling was observed even after the production. When the above-mentioned cold heat cycle was less than 2 cycles, a leak occurred. Therefore, in the above-mentioned hot and cold cycle test, at 2〇〇 The membrane module which has no leakage after the cycle can be used without any problem in practical use. (Example 12) Hereinafter, the results obtained by performing the thermal cycle test under high pressure are shown. In addition to hollow fiber membranes, and examples The membrane module was fabricated in the sample. After the manufacture, it was observed that each membrane module was completely free of peeling.
