Description

Technical Field

[0001] The present invention relates to the technical field of MBR, in particular to an MBR hollow fiber membrane component. Background Art

[0002] In the field of sewage treatment and water resource reuse, MBR, also known as membrane bioreactor, is a new water treatment technology that combines a membrane separation unit with a biological treatment unit. At present, hollow fiber MBR membrane components mostly exist in the form of curtain components, that is, the two ends of multiple bundles of hollow fiber membrane fibers are respectively cast into two water collection pipes with epoxy glue and polyurethane glue to form curtain membrane components, and then these membrane components are installed on the membrane frame.

[0003] In the prior art, the hollow fiber membrane assembly is generally a combination structure of a frame and multiple curtain membranes. When a problem occurs with the curtain fiber membrane, it is often necessary to first dismantle the connecting pipe between the curtain fiber membrane and the frame. Therefore, it is not convenient to quickly install, dismantle and remove the curtain fiber membrane for repair and replacement. In the process of removing the curtain fiber membrane, it is generally necessary to install a corresponding lifting mechanism on the upper part of the fiber membrane assembly to lift and lower the curtain fiber membrane in the vertical direction, which occupies a large amount of upper space. When carrying out the MBR membrane process in the groundwater plant, the overall clearance height is often relatively large, which easily leads to waste of the overall upper space of the fiber membrane assembly.

[0004] Therefore, in order to reduce the overall clearance height of the MBR membrane process of the groundwater plant, the present application specifically proposes an MBR hollow fiber membrane component to solve the above technical problems. Summary of the Invention

[0005] The main purpose of the present invention is to provide an MBR hollow fiber membrane assembly that can save the upper space of the hollow fiber membrane assembly and can quickly disassemble and assemble the hollow fiber membrane connecting pipe when the hollow fiber membrane is taken out from the frame.

[0009] Preferably, the connecting lifting mechanism includes a sliding bracket arranged on an arc-shaped electric guide rail through a movable slider, a connecting seat arranged on the sliding bracket, an electric push rod installed on the connecting seat, a connecting bracket located at the bottom end of the electric push rod, two sets of connecting racks arranged on the connecting bracket, and a hook-shaped claw located at the bottom end of the connecting rack for lifting and grabbing the curtain fiber membrane.

[0010] Preferably, a rotation groove is provided at the bottom end of the sliding bracket, and a rotating wheel for installing the connecting seat rotates in the rotation groove.

[0011] Preferably, both ends of the connecting bracket are provided with sliding grooves that pass through the upper and lower parts, and connecting sliders for installing the connecting racks are slid into the sliding grooves, and the tops of the connecting sliders are provided with connecting plates for connecting to the connecting seat through mutually hinged hinge shafts;

[0012] The connecting and lifting mechanism further includes a limiting telescopic rod with two ends respectively arranged on different connecting racks.

[0013] Preferably, the curtain-type fiber membrane includes a fiber membrane body, a soft outer frame for fixing the fiber membrane body, a lifting frame arranged on the soft outer frame for cooperating with hook-type claws to allow the connecting lifting mechanism to drive the soft outer frame and the fiber membrane body to move, and a pipe connector arranged on the fiber membrane body for driving the fiber membrane body to connect and separate the pipes on the outer frame assembly during the lifting and lowering movement of the connecting rack.

[0014] Preferably, the pipe connector is composed of a movable pipe, a limiting sleeve slidably sleeved on the outside of the movable pipe, and a connecting gear arranged on the outside of the limiting sleeve for meshing with the connecting rack;

[0015] An annular protrusion is provided on the outer side of one end of the limiting sleeve for limiting the rotation of the limiting sleeve on the fiber membrane body. A limiting groove is provided inside the limiting sleeve along the length direction. A limiting slider is provided in the middle of the movable tube for sliding in the limiting groove. External threads are provided at both ends of the movable tube for threaded connection to the fiber membrane body and the outer frame component pipe.

[0016] Preferably, the outer frame assembly includes an outer frame body for installing multiple curtain-type fiber membranes, multiple positioning base plates arranged at the bottom of the outer frame body for installing and positioning the curtain-type fiber membranes on the outer frame body, a limiting block arranged on the outer frame body for fixing the position of the soft outer frame and limiting the lifting and lowering movement of the soft outer frame on the outer frame body, a connecting pipeline for connecting to a pipeline connector and transporting water, and a pipeline mounting frame arranged on the outer frame body for installing and positioning the connecting pipeline, and the positioning base plate is provided with multiple positioning grooves for engaging the bottom of the fiber membrane body.

[0017] Preferably, the connecting pipeline includes a water pipe and a connecting main pipe connected to each other, the connecting main pipe is provided with a plurality of connecting branches for connecting to the pipe connectors for water flow, and a supporting rack is provided at the bottom of the connecting branch for supporting and placing the pipe connectors.

[0018] The present invention provides a MBR hollow fiber membrane module. Compared with the prior art, the present invention has the following advantages:

[0019] 1. The present invention provides a lifting platform and a connecting lifting mechanism for connecting the curtain fiber membrane, and utilizes mutually connected and coordinated load-bearing plates and an L-arc-shaped arc-shaped electric guide rail. When the curtain fiber membrane is taken out, the curtain fiber membrane can be lifted and lowered as a whole through the connecting lifting mechanism, and the connecting lifting mechanism is synchronously moved on the arc-shaped electric guide rail when the curtain fiber membrane is lifted, so that the curtain fiber membrane can be taken out in a curved shape during the rising process, which can greatly save the overall upper space of the MBR hollow fiber membrane assembly, reduce the overall clearance height of the MBR membrane process, and avoid space waste.

[0020] 2. Since the curtain-type fiber membrane is provided with a lifting frame for lifting the connecting fiber membrane body, the present invention sets a connecting lifting mechanism and utilizes the rapid telescopic control of the electric push rod to allow the connecting bracket and the connecting seat to move closer and farther apart when cooperating with the hinge shaft to allow the connecting plate to control the hook-shaped claws to move closer and farther apart through the connecting slider and the connecting rack, thereby facilitating the rapid and stable positioning of the fiber membrane body on the lifting frame for lifting operations.

[0021] 3. The present invention sets a plurality of limit blocks on the outer frame body, which can fix the position of the soft outer frame when the curtain fiber membrane is in operation and limit the soft outer frame from moving up and down on the outer frame body when the curtain fiber membrane is raised and lowered, so as to avoid affecting other fiber membrane bodies when the curtain fiber membrane is lifted and removed.

[0022] 4. The present invention connects to the connecting branch pipe used for water transportation by arranging a pipe connector located on the fiber membrane body. Since the connecting rack and the connecting gear of the connecting lifting mechanism are engaged with each other during the process of hoisting and connecting the curtain fiber membrane, when the connecting lifting mechanism moves down to prepare for connecting the curtain fiber membrane, it will engage and drive the connecting gear to rotate to separate the movable pipe from the connecting branch pipe thread, thereby quickly disassembling and removing the connecting pipe between the curtain fiber membrane and the frame before the curtain fiber membrane is hoisted and removed.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] In the embodiment, see Figures 1 to 9 .

[0041] like Figure 1 、 Figure 2 and Figure 5 As shown, the present invention provides an MBR hollow fiber membrane module, comprising an outer frame assembly 3 with a plurality of curtain-type fiber membranes 5 arranged therein, a hoisting platform 2 arranged above the outer frame assembly 3 for horizontal movement via a slide rail structure 1, and a connecting lifting mechanism 4 arranged on the hoisting platform 2 for quickly installing and connecting the curtain-type fiber membranes 5, wherein:

[0042] The hoisting platform 2 is composed of a mounting plate frame 23 arranged on the slide rail structure 1, a load-bearing plate 22 located at the bottom of the mounting plate frame 23, and an L-shaped arc-shaped electric guide rail 21 located at the top of the mounting plate frame 23 for driving the connection lifting mechanism 4 to move.

[0043] In the specific implementation, since the connecting lifting mechanism 4 is connected to the installed curtain fiber membrane 5, and the connecting lifting mechanism 4 is installed on the arc-shaped electric guide rail 21, the curtain fiber membrane 5 can be hoisted and lifted as a whole through the connecting lifting mechanism 4 when the curtain fiber membrane 5 is taken out, and the connecting lifting mechanism 4 is synchronously moved on the arc-shaped electric guide rail 21 when the curtain fiber membrane 5 is hoisted. By using the mutually connected and coordinated supporting plates 22 and the L-shaped arc-shaped electric guide rail 21, the curtain fiber membrane 5 can be taken out in a curved shape during the rising process, and the bottom curtain fiber membrane 5 is supported on the upper surface of the supporting plate 22, thereby greatly saving the overall upper space of the MBR hollow fiber membrane assembly, reducing the overall clearance height of the MBR membrane process, and avoiding the phenomenon of space waste.

[0044] It should be noted that the above-mentioned slide rail structure 1 and arc-shaped electric guide rail 21 are both existing technologies. Therefore, the slide rail structure 1 and the arc-shaped electric guide rail 21 can be directly used using existing technologies, so they will not be described in detail here. The arc-shaped electric guide rail 21 should be set as an L-shaped arc-shaped guide rail structure with a horizontal upper part and a vertical lower part when in use.

[0045] At this time Figure 7 As shown, the connecting lifting mechanism 4 includes a sliding bracket 41 set on the arc-shaped electric guide rail 21 through a movable slider 413, a connecting seat 42 set on the sliding bracket 41, an electric push rod 43 installed on the connecting seat 42, a connecting bracket 45 located at the bottom end of the electric push rod 43, two sets of connecting racks 46 set on the connecting bracket 45, and a hook-shaped claw 47 located at the bottom end of the connecting rack 46 for lifting and grabbing the curtain fiber membrane 5.

[0046] In a specific implementation, the electric push rod 43 is used to control the connection bracket 45 to move downward, so that the hook-shaped claw 47 can be inserted into the lifting part of the curtain fiber membrane 5 for engagement. It should be noted that the hook-shaped claw 47 can be set as an elastic metal claw.

[0047] like Figure 8 As shown, in a specific embodiment, a rotating groove 412 is opened at the bottom end of the sliding bracket 41, and a rotating wheel 411 for installing the connecting seat 42 rotates in the rotating groove 412. When the arc electric guide rail 21 controls the movement after the hook-type claw 47 connects to the curtain fiber membrane 5, it can avoid the connection lifting mechanism 4 from interfering with the arc electric guide rail 21 during the movement process, and ensure that the connection lifting mechanism 4 drives the normal movement of the curtain fiber membrane 5.

[0048] In addition, Figure 8 As shown, in a specific embodiment, both ends of the connecting bracket 45 are provided with sliding grooves 451 that pass through the upper and lower parts, and connecting sliders 452 for installing the connecting rack 46 slide in the sliding grooves 451. The connecting sliders 452 slide with limited support in the sliding grooves 451, and a connecting plate 453 is provided on the top of the connecting slider 452 for connecting the curtain fiber membrane 5 to the connecting seat 42 through the hinged hinge shafts 44 and the hinged hinge shafts 44 for use.

[0049] It should be noted that the electric push rod 43 can directly adopt the electric push rod 43 in the prior art; the connecting rack 46 mentioned above is used here as a connecting piece of the hook-shaped claw 47.

[0050] In a specific implementation, by setting up a connecting lifting mechanism 4 and utilizing the rapid telescopic control of the electric push rod 43, the connecting bracket 45 and the connecting seat 42 can be moved closer or further away by cooperating with the hinge shaft 44 to allow the connecting plate 453 to control the hook-shaped claws 47 to move closer or further away from each other through the connecting slider 452 and the connecting rack 46. Therefore, the connecting lifting mechanism 4 can stably connect to the lifting part of the fiber membrane body 51 by controlling the lifting and lowering movement of the hook-shaped claws 47.

[0051] It should be noted here that the above-mentioned hook-shaped claw 47 can be used with the hook-shaped claw disclosed in the prior art, or a corresponding claw movable mechanism can be installed on the basis of the hook-shaped claw to allow the bottom of the hook-shaped claw to move, thereby facilitating the hook-shaped claw 47 to be quickly connected to the lifting part of the fiber membrane body 51.

[0052] At this time, the connecting lifting mechanism 4 also includes a limiting telescopic rod 48 with two ends respectively arranged on different connecting racks 46, which is used to limit and ensure that the different connecting racks 46 always maintain linear horizontal movement during the process of moving away and approaching, and ensure the overall connection quality of the connecting lifting mechanism 4 after the hook-type claw 47 connects to the curtain fiber membrane 5.

[0053] like Figure 5 As shown, in a specific embodiment, the curtain-type fiber membrane 5 includes a fiber membrane body 51, a soft outer frame 52 for fixing the fiber membrane body 51, a hanging frame 53 arranged on the soft outer frame 52 for cooperating with the hook-shaped claws 47 to allow the connecting lifting mechanism 4 to drive the soft outer frame 52 and the fiber membrane body 51 to move, and a pipe connector 54 arranged on the fiber membrane body 51 for driving the fiber membrane body 51 to connect and separate with the pipe on the outer frame assembly 3 during the lifting and lowering movement of the connecting rack 46.

[0054] It should be noted that the fiber membrane body 51 can be directly used as the hollow fiber membrane product in the existing technology; the soft outer frame 52 is set to a flexible soft material to ensure the overall smooth bending of the curtain fiber membrane 5 during the lifting process.

[0055] Among them, such as Figure 6 and Figure 9 As shown, the pipe connector 54 is composed of a movable pipe 541 , a limiting sleeve 542 slidably sleeved on the outside of the movable pipe 541 , and a connecting gear 546 arranged on the outside of the limiting sleeve 542 for meshing with the connecting rack 46 .

[0056] Specifically, an annular protrusion 543 is provided on the outer side of one end of the limiting sleeve 542 for limiting the rotation of the limiting sleeve 542 on the fiber membrane body 51, a limiting groove 544 is provided inside the limiting sleeve 542 along the length direction, and a limiting slider 545 is provided in the middle of the movable tube 541 for sliding in the limiting groove 544, and both ends of the movable tube 541 are respectively provided with external threads for threaded connection to the fiber membrane body 51 and the pipeline of the outer frame assembly 3.

[0057] During the water delivery process, the movable tube 541 can rotate synchronously with the rotation of the limiting sleeve 542 through the combined structure of the limiting slider 545 and the limiting groove 544. Since the movable tube 541 is threadedly connected to the fiber membrane body 51, it can be telescoped and moved to the outside of the limiting sleeve 542 during the rotation of the movable tube 541. Therefore, during the rotation of the limiting sleeve 542, the movable tube 541 can rotate and move on the inner thread of the limiting sleeve 542 to telescope.

[0058] It should be noted that the fiber membrane body 51 will transport water through the internal water transfer channels of the upper and lower fixed parts during the water delivery process. At this time, other pipes can be installed between the upper and lower fixed parts of the fiber membrane body 51 to transfer the bottom water flow delivery operation to the other side of the upper fixed part of the fiber membrane body 51 for water delivery operation. At this time, the connection of the water inlet and outlet pipes of the fiber membrane body 51 during water delivery can be achieved through the pipe connectors 54 on both sides of the upper fixed part.

[0059] In the specific implementation, since the connecting rack 46 and the connecting gear 546 of the connecting lifting mechanism 4 are engaged with each other during the process of hoisting and connecting the curtain fiber membrane 5, when the connecting lifting mechanism 4 moves down to prepare for connecting the curtain fiber membrane 5, it will engage and drive the connecting gear 546 to rotate to allow the movable tube 541 to be threadedly separated from the connecting branch pipe 352, thereby quickly disassembling and removing the connecting pipe between the curtain fiber membrane 5 and the outer frame assembly 3 before the curtain fiber membrane 5 is hoisted and removed. When the electric push rod 43 controls the connecting rack 46 to drive the hook-type claw 47 to approach each other for hoisting and connecting the hoisting frame 53, the connecting rack 46 is separated from the connecting gear 546. At this time, the connecting rack 46 can be smoothly moved up to allow the hook-type claw 47 to be connected and supported on the hoisting frame 53 to complete the hoisting operation of the curtain fiber membrane 5.

[0060] like Figure 3 As shown, in a specific embodiment, the outer frame assembly 3 includes an outer frame body 31 for installing multiple curtain fiber membranes 5, multiple positioning base plates 32 arranged at the bottom of the outer frame body 31 for installing and positioning the curtain fiber membranes 5 on the outer frame body 31, a limiting block 33 arranged on the outer frame body 31 for fixing the position of the soft outer frame 52, a connecting pipe 35 for connecting to the pipe connector 54 and transporting water, and a pipe mounting frame 34 arranged on the outer frame body 31 for installing and positioning the connecting pipe 35.

[0061] Among them, the limiting block 33 can fix the position of the soft outer frame 52 when the curtain fiber membrane 5 is in operation and limit the soft outer frame 52 to move up and down on the outer frame body 31 when the curtain fiber membrane 5 is raised and lowered, so as to avoid affecting other fiber membrane bodies 51 when the curtain fiber membrane 5 is lifted and removed. A plurality of positioning grooves 321 for engaging the bottom of the fiber membrane body 51 are also provided on the positioning base plate 32.

[0062] At this time Figure 4 As shown, the connecting pipeline 35 includes a water pipe 354 and a connecting main pipe 351 that are connected to each other. The connecting main pipe 351 is provided with a plurality of connecting branches 352 for connecting to the pipeline connector 54 for water flow.

[0063] During the water supply connection, the entire pipe of the connecting pipeline 35 can be used for the water inlet and outlet operations of the curtain fiber membrane 5, and during the installation process of the curtain fiber membrane 5, a supporting rack 353 is set at the bottom of the connecting branch pipe 352, which can support the placement of the pipe connector 54.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0065] In addition, it should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0066] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features.

In addition, in the embodiments of the present invention, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
