Description

Installation structure of a fluid larva filter device

[0001] The present invention relates to an installation structure of a fluid larva filtering device, and more particularly, to a structure for installing a fluid larva filtering device in a waterway to effectively capture larvae contained in a fluid (water) moving in a waterway.

[0002]

[0003] If larvae (worms) are introduced into water treatment ponds or other water treatment plants during the water treatment process, many difficulties arise in water quality management.

[0004] In particular, in the summer, substances that cause taste or odor in tap water cause significant inconvenience to users in using water, which causes many difficulties in operation management and customer management.

[0005] To solve this problem, a fixed filter net is currently installed in the sedimentation tank outlet to block the inflow of larvae. However, due to the turbidity of the sedimentation water, the installed filter net becomes clogged in a short period of time, preventing it from functioning properly. In addition, the effectiveness of the fixed filter net operation itself is greatly reduced due to the disadvantage of having to replace the filter freely.

[0006] In addition, these filter devices, or filtration devices, are installed in waterways, and larvae and other organisms often enter through the gap between the waterway and the filtration device.

[0041] The purpose, specific advantages, and novel features of the present invention will become more apparent from the following detailed description and examples in conjunction with the accompanying drawings. In this specification, when assigning reference numbers to components in each drawing, it should be noted that, as much as possible, identical components are given the same numbers even if they are shown in different drawings. In addition, in describing the present invention, if a detailed description of a related known technology is judged to unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. In this specification, terms such as first, second, etc. are used to distinguish one component from another, and the components are not limited by the terms. In the accompanying drawings, some components are exaggerated, omitted, or schematically illustrated, and the size of each component does not entirely reflect the actual size.

[0042] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0043]

[0044] The fluid larva filtering device (100) of the present invention is for capturing larvae contained in a fluid (water) moving in a water channel (300), and as shown in FIGS. 1 to 6, comprises a housing (110), a supply roll (120), a recovery roll (130), a guide member (140), a filter (150), and a driving unit (160).

[0045] The housing (110) is hinged so that the upper case and the lower case can rotate, and the interior of the housing (110) is opened by the rotation of the upper case.

[0046] As shown in FIG. 4, the above supply roll (120) is rotatably mounted on the housing (110), and a filter (150) is wound around it.

[0047] As shown in FIG. 4, the above recovery roll (130) is rotatably mounted on the housing (110), and the filter (150) unwound from the supply roll (120) is wound after filtering larvae in the fluid.

[0048] At this time, it is preferable that the larvae are captured and trapped in the filter (150) by the structure, material, etc. of the filter (150).

[0049] The above recovery roll (130) is placed lower than the above supply roll (120).

[0050] The above guide member (140) is mounted lengthwise downward from the lower portion of the housing (110) as shown in FIG. 1.

[0051] The above guide member (140) has a plurality of holes formed therein.

[0052] The above guide member (140) ensures that the filter (150) remains in a downwardly unfolded state without shaking.

[0053] As shown in FIG. 4, the filter (150) is wound on the supply roll (120) and then, as it is unwound toward the guide member (140), it comes into contact with the fluid, filters the larvae contained in the fluid, and is then wound on the recovery roll (130).

[0054] A rotating roller (141) is mounted at the lower end of the above guide member (140).

[0055] The above filter (150) changes its movement direction from downward to upward when it comes into contact with the outer surface of the above rotating roller (141).

[0056] Based on the above guide member (140), the filter (150) rises in the direction in which the fluid flows and moves to the recovery roll (130).

[0057] If, in contrast to the present embodiment, the filter (150) moves downward in the direction in which the fluid flows in and upward in the direction in which the fluid flows out based on the guide member (140) to the recovery roll (130), when the filter (150) with the larvae captured moves upward from the downward direction, a problem occurs in which the larvae captured in the filter (150) are separated by the current of the fluid and may flow back into the fluid.

[0058] However, since the present invention causes the filter (150) to descend in the direction in which the fluid flows out and to rise in the direction in which the fluid flows in, it is possible to prevent larvae captured in the filter (150) from being separated from the filter (150) and flowing back into the water channel (300).

[0059] The above driving unit (160) moves the filter (150).

[0060] The above driving unit (160) is composed of a motor (not shown), a first filter transport unit (161), and a second filter transport unit (165).

[0061] The first filter transport unit (161) and the second filter transport unit (165) may be operated by separate motors, but it is preferable to operate them by being connected by a belt by one motor as in this embodiment.

[0062] As shown in FIGS. 3 and 4, the first filter transport unit (161) is placed in the housing (110) between the supply roll (120) and the guide member (140) and forcibly moves the filter (150) wound on the supply roll (120) toward the guide member (140).

[0063] In addition to forcibly moving the filter (150) wound on the supply roll (120) toward the guide member (140), the first filter transport unit (161) may also forcibly move the filter (150) moving along the guide member (140) toward the recovery roll (130).

[0064] In this embodiment, the first filter transport unit (161) is configured to forcibly move the filter (150) from the supply roll (120) toward the guide member (140), and at the same time, to forcibly move the filter (150) from the guide member (140) toward the recovery roll (130).

[0065] Of course, in some cases, the first filter transport unit (161) may forcibly move the filter (150) only in the direction of the guide member (140) from the supply roll (120).

[0066] In this embodiment, the first filter transport unit (161) includes a first driving roller (161a), a first driven roller (161b), and a second driven roller (161c).

[0067] The above first drive roller (161a) is rotatably mounted on the housing (110) and rotates by external force, i.e., by driving of a motor.

[0068] The first driven roller (161b) is rotatably mounted on the housing (110) and is positioned adjacent to one side of the first driving roller (161a) with the filter (150) drawn from the supply roll (120) interposed therebetween.

[0069] The filter (150) extracted from the supply roll (120) passes between the first drive roller (161a) and the first driven roller (161b) and causes the first driven roller (161b) to rotate by frictional force.

[0070] The second driven roller (161c) is rotatably mounted on the housing (110) and is positioned adjacent to the other side of the first driven roller (161a) with the filter (150) moving along the guide member (140) interposed therebetween.

[0071] The filter (150) that moves along the above guide member (140) passes between the first driving roller (161a) and the second driven roller (161c) and rotates the second driven roller (161c) by frictional force.

[0072] The filter (150) is forced to move upward and downward based on the first filter transport unit (161) by the first filter transport unit (161) as described above.

[0073] At this time, a friction ring (not shown) that comes into contact with the filter (150) and forcibly moves the filter (150) is protrudingly mounted on the outer surface of the first driving roller (161a), the first driven roller (161b), and the second driven roller (161c).

[0074] The above friction ring is made of a rubber ring or the like to enable the filter (150) to move smoothly without slipping due to friction.

[0075] As described above, the first filter transport unit (161) comes into direct contact with the filter (150) and forcibly moves the filter (150).

[0076] The above first filter transport unit (161) may further include a connecting member (161e).

[0077] As shown in FIGS. 3 and 6, the above connecting member (161e) is rotatably connected to the rotational axis of the first driving roller (161a) at its center, is fitted to the rotational axis of the first driven roller (161b) at one end, and is fitted to the rotational axis of the second driven roller (161c) at the other end.

[0078] As shown in Fig. 6(b), when the connecting member (161e) is rotated by an external force, the first driven roller (161b) and the second driven roller (161c) are separated from the first driving roller (161a).

[0079] To this end, a moving groove is formed long in the vertical direction on the side of the housing (110) for the first driven roller (161b) and the second driven roller (161c) to move.

[0080] In this way, when the first driven roller (161b) and the second driven roller (161c) are spaced apart from the first driving roller (161a), the filter (150) can be easily inserted and replaced between the first driven roller (161b) and the first driving roller (161a) and between the second driven roller (161c) and the second driving roller (165a) during initial installation and replacement of the filter (150).

[0081] In addition, when the external force that rotated the connecting member (161e) is removed, it is preferable to install a separate elastic member so that the connecting member (161e), the first driven member, and the second driven member return to their original positions.

[0082] As shown in FIGS. 4 and 5, the second filter transport unit (165) moves the filter (150) that is wound by the recovery roll (130) to rotate the recovery roll (130).

[0083] The second filter transport unit (165) forcibly moves the filter (150) while directly contacting the filter (150).

[0084] This second filter transport unit (165) comprises a second drive roller (165a), a moving roller (165b), a link (165d), and a power transmission member (165f).

[0085] The above second drive roller (165a) is rotatably mounted on the housing (110) and rotates by external force, i.e., by driving of a motor.

[0086] The above moving roller (165b) is placed inside the housing (110) and has a plurality of saw blades formed on the outer surface.

[0087] The above link (165d) is rotatably coupled at one end to the second drive roller (165a), and the other end is rotatably coupled to the moving roller (165b).

[0088] The moving roller (165b) is supported on the second driving roller (165a) by the link (165d).

[0089] The above power transmission member (165f) transmits the rotational force of the second drive roller (165a) to the moving roller (165b) to rotate the moving roller (165b).

[0090] When the moving roller (165b) rotates, the saw blade formed on the outer surface of the moving roller (165b) comes into contact with the filter (150) and forcibly moves the filter (150), and the recovery roll (130) rotates due to the forced movement of the filter (150).

[0091] And, as shown in Fig. 5(b), as the diameter of the recovery roll (130) increases, the moving roller (165b) moves away from the recovery roll (130) so that the other end of the link (165d) rotates backwards around one end of the link (165d).

[0092] Through this, the saw blade formed on the outer surface of the moving roller (165b) can be made to always be in close contact with the filter (150) wound around the recovery roll (130) to forcibly move the filter (150).

[0093] At this time, it is preferable that the moving roller (165b) be positioned lower than the top of the recovery roll (130) to force the filter (150) to move downward.

[0094] And, the end of the filter (150) is connected to the recovery roll (130).

[0095] When the moving roller (165b) rotates by the structure described above, the saw blade formed on the outer surface of the moving roller (165b) rotates to forcibly move the filter (150) arranged on the outer surface of the recovery roll (130), and the forcible movement of the filter (150) causes the recovery roll (130) to rotate forcibly, thereby winding the filter (150).

[0096] In addition, a mounting projection (165e) is formed protruding at one end of the link (165d) to which the second driving unit (160) is coupled.

[0097] In addition, the second filter transport unit (165) may further include a spring (165g) having one end coupled to the mounting projection (165e) and the other end coupled to the housing (110).

[0098] By the elastic force of the spring (165g), the other end of the link (165d) and the moving roller (165b) are rotated and brought into close contact with the direction of the recovery roll (130), so that even if the diameter of the recovery roll (130) changes due to the filter (150) being wound around the recovery roll (130), the saw blade of the moving roller (165b) can always be brought into strong contact with the filter (150).

[0099] As described above, the present invention captures larvae contained in a fluid while the filter (150) continuously moves, and moves the filter (150) in which the larvae are captured out of the fluid and recovers it while drying it, thereby preventing decomposition and decay of the larvae, and thus allows inspection of the larvae to be conducted.

[0100] In addition, since the filter (150) is continuously supplied and recovered, it is possible to prevent the filter (150) from being easily clogged by larvae and having to be replaced frequently, and when all of the filters (150) supplied from the supply roll (120) are used, the worker can replace them in advance through a separate notification signal, etc.

[0101] In addition, the installation structure of the fluid larva filtering device of the present invention includes a holder (200) and a filtering device (100), as shown in FIGS. 7 to 11.

[0102] As shown in Fig. 7, a connecting groove (310) is formed along the inner wall of the water channel (300) through which the fluid moves.

[0103] The above-mentioned connecting groove (310) may be formed only on both sides of the water channel (300), or may be additionally formed on the lower surface of the water channel (300).

[0104] The above holder (200) is inserted into the coupling groove (310) formed along the inner wall of the water channel (300).

[0105] The above filtering device (100) is the filtering device (100) of the present invention described above, and comprises a guide member (140) that protrudes downwardly and is inserted into the inside of the holder (200), and a filter (150) that is arranged to wrap around the guide member (140) in the vertical direction and comes into contact with the fluid moving through the water channel (300) to capture larvae contained in the fluid.

[0106] The above holder (200) is composed of a frame portion (210) and a contact member (220).

[0107] As shown in Fig. 8, the above frame portion (210) is formed in an approximately hollow rectangular shape, is inserted into the coupling groove (310), and is open in the forward and backward direction in which the fluid moves.

[0108] The guide member (140) is inserted and mounted inside the frame portion (210), and the housing (110) of the filter device (100) is placed on the upper portion of the frame portion (210).

[0109] The above frame portion (210) includes a frame front portion (211), a frame rear portion (212), a frame side portion (213), and a mounting groove portion (214).

[0110] The above frame front part (211) is placed at the front in the direction in which the fluid flows.

[0111] The above frame rear part (212) is placed at the rear of the frame front part (211).

[0112] The above frame side portion (213) connects the frame front portion (211) and the frame rear portion (212) to each other.

[0113] The above mounting groove (214) is formed by being opened inward by the frame front portion (211), the frame rear portion (212), and the frame side portion (213).

[0114] By this configuration, the frame portion (210) has a cross-section that is approximately in the shape of '┌┐'.

[0115] The above guide member (140) is inserted from the upper part to the lower part of the mounting groove (214).

[0116] As shown in FIGS. 9 and 10, the above-mentioned adhesion member (220) is mounted in the mounting groove (214) of the frame portion (210) and has the function of pressing the frame portion (210) into the joining groove (310) formed in the water channel (300).

[0117] As shown in FIG. 9, the adhesive member (220) mounted on the mounting groove (214) pushes the frame portion (210) forward as shown in FIG. 10 while the frame portion (210) is inserted into the joining groove (310) of the water channel (300) to bring the front surface of the frame front portion (211) into close contact with the front wall surface of the joining groove (310).

[0118] By the above-mentioned adhesion member (220), the front surface of the frame front part (211) is adhered to the front wall surface of the coupling groove (310), so that when the frame part (210) is placed in the coupling groove (310), the passage of larvae in the fluid through the gap between the frame part (210) and the coupling groove (310) can be blocked.

[0119] At this time, it is preferable that the first adhesive pad (215) be combined with the front surface of the frame front part (211).

[0120] When the front surface of the frame front part (211) is brought into close contact with the front wall surface of the coupling groove (310) by the above-mentioned adhesion member (220), the first adhesion pad (215) can more effectively block the gap between the frame part (210) and the coupling groove (310) to more effectively block the passage of larvae in the fluid.

[0121] As shown in FIGS. 8 to 10, the contact member (220) that pushes the frame member (210) forward and contacts the front surface of the frame member (210) with the coupling groove (310) comprises a lifting block (221), a block moving member (222), and a pressure block (223).

[0122] The above-mentioned lifting block (221) is arranged to move up and down inside the above-mentioned mounting groove (214).

[0123] The above block moving member (222) moves the above lifting block (221) up and down.

[0124] The above pressure block (223) protrudes toward the rear of the frame part (210) by the movement of the above lifting block (221).

[0125] For this purpose, a cut groove (216) is formed on the rear surface of the frame (212).

[0126] Accordingly, as illustrated in FIG. 10, the pressure block (223) moves to protrude toward the rear of the frame rear portion (212) by penetrating the cut groove (216) through the movement of the lifting block (221) by the block moving member (222).

[0127] The above pressure block (223) protrudes toward the rear of the frame rear portion (212) and comes into contact with the rear wall surface of the coupling groove (310), and as the pressure block (223) protrudes further due to the movement of the lifting block (221), the frame portion (210) moves forward, and the front surface of the frame front portion comes into close contact with the front wall surface of the coupling groove (310).

[0128] The above-mentioned adhesion member (220) further includes a fixed block (224) that is fixedly connected to the mounting groove (214) in the opposite direction of the lifting block (221) with the pressure block (223) interposed therebetween.

[0129] The above pressure block (223) has first inclined surfaces formed on the upper and lower sides, respectively.

[0130] The above-mentioned lifting block (221) and fixed block (224) are each formed with a second inclined surface that is in contact with the first inclined surface.

[0131] And, the lifting block (221) is placed below the pressure block (223), and the fixed block (224) is placed above the pressure block (223).

[0132] The above block moving member (222) is made of a long rod-shaped bolt and is positioned to penetrate the fixed block (224) and the pressure block (223) in the vertical direction.

[0133] The above block moving member (222) is screw-connected to the lifting block (221) placed below the pressure block (223).

[0134] When the block moving member (222) rotates, the lifting block (221) screw-coupled to the block moving member (222) rises, and the first and second inclined surfaces come into contact, thereby causing the pressure block (223) to move to protrude toward the rear of the frame rear portion (212).

[0135] The above pressure block (223) has a long hole (223a) formed in the direction of movement of the pressure block (223), and the block moving member (222) is arranged to penetrate the long hole (223a).

[0136] Accordingly, when the pressure block (223) moves forward and backward, the pressure block (223) can move smoothly without any obstruction from the block moving member (222).

[0137] Meanwhile, a second adhesive pad (217) is placed between the inner surface of the front frame (211) and the guide member (140).

[0138] In this embodiment, the second adhesive pad (217) is coupled to the inner surface of the front frame portion (211).

[0139] And, as shown in Fig. 11, a hanging hole (142) open downward is formed on the lower side of the guide member (140).

[0140] Additionally, a hook (218) that is hooked onto the hook hole (142) is formed protruding on the inner surface of the frame side (213).

[0141] At this time, a third slope (143) is formed in the above-mentioned hanging hole (142).

[0142] In a state as shown in Fig. 11(a), when the guide member (140) is lowered and inserted into the interior of the mounting groove (214), as shown in Fig. 11(b), the third inclined surface (143) comes into contact with the catch (218), and the guide member (140) moves forward with the second adhesion pad (217) in between, so as to be in close contact with the inner surface of the front face of the frame (211).

[0143] As described above, the guide member (140) is in close contact with the inner surface of the front frame portion (211) with the second adhesive pad (217) interposed therebetween, thereby preventing larvae from passing through the gap between the guide member (140) and the front frame portion (211).

[0144] In addition, a support protrusion (219) is formed protrudingly on the inner surface of the front part of the frame (211) as shown in FIGS. 8 and 11.

[0145] At this time, the support protrusion (219) is formed to be inclined in the vertical direction.

[0146] And, as shown in FIG. 7 and FIG. 11, the guide member (140) has a support groove (144) formed into which the support protrusion (219) is selectively inserted.

[0147] As shown in Fig. 11, when the guide member (140) is inserted into the mounting groove (214), the front part of the frame (211) is initially lowered while being moved backward by the support protrusion (219).

[0148] Thereafter, when the above-mentioned hook (218) is fitted into the hook groove, the above-mentioned support protrusion (219) is inserted into the above-mentioned support groove (144), thereby allowing the above-mentioned guide member (140) to move forward, while preventing the above-mentioned guide member (140) from moving left and right.

[0149] By initially inserting the guide member (140) away from the frame front part (211) when it is inserted into the mounting groove (214), the second friction pad mounted on the inner surface of the frame front part (211) and the guide member (140) can be prevented from coming into contact, thereby preventing the guide member (140) from descending smoothly.

[0150] And after the guide member (140) has been lowered, the guide member (140) is made to be in close contact with the inner surface of the front part of the frame (211), thereby more effectively blocking the inflow of larvae.

[0151] As described above, the present invention can effectively block larvae from entering through the gap between the joining groove (310) of the water channel (300), the holder (200), and the guide member (140) of the filter device (100).

[0152]

[0153] The installation structure of the fluid larva filtering device of the present invention is not limited to the above-described embodiment, and can be implemented by various modifications within the scope permitted by the technical concept of the present invention.

[0154] Although the present invention has been described in detail through examples, this is intended to specifically explain the present invention, and the installation structure of the fluid larva filtering device according to the present invention is not limited thereto, and it will be apparent that modifications or improvements can be made by a person having ordinary knowledge in the relevant field within the technical spirit of the present invention.

[0155] All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be made clear by the appended claims.
