Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and specifically refers to a sewage treatment ultrafiltration device. Background Art

[0002] A sewage ultrafiltration device is a device that uses an ultrafiltration membrane for water treatment. Its core component is the ultrafiltration membrane. The ultrafiltration device usually consists of a pretreatment system, an ultrafiltration membrane module, a pressurization system, a control system, and a cleaning system. The commonly used ultrafiltration membrane is a hollow fiber membrane. The membrane layer is in the shape of hollow fibers and has a large membrane area. Sewage flows inside or outside the fibers, and can effectively remove suspended solids, bacteria, viruses, colloids, and certain dissolved organic substances in water. The separation principle of the ultrafiltration membrane is based on sieving action, that is, under a certain pressure, water and small molecule substances pass through the membrane pores, while macromolecule substances are retained on the membrane surface.

[0003] In order to increase the sewage treatment capacity per unit time, the existing ultrafiltration devices usually need to connect multiple hollow fiber membranes in parallel (parallel connection means connecting the water inlet ends of all hollow fiber membranes to the same water inlet pipe, so that the raw water is simultaneously distributed to each membrane module for filtration, and the water outlet ends of each membrane module are also connected to the same water outlet pipe to collect the produced water) and form a hollow fiber membrane group. When connecting in parallel, multiple hollow fiber membranes need to be distributed and installed in a rectangular array.

[0004] When installing multiple hollow fiber membranes in a rectangular array as described above, a large installation area is required, so it cannot be installed in places with limited space, reducing the application range of the device; and after treating sewage for a period of time, it is necessary to use backwashing to clean each hollow fiber membrane. The entire cleaning process takes some time to complete. In the entire cleaning process of the above parallel connection method, the device needs to be in a completely shutdown state, so that sewage cannot be continuously treated, affecting the use efficiency of the device.

[0036] The following further elaborates on the present invention with reference to the accompanying drawings.

[0037] Combined with the attached Figure 1 and the attached Figure 2 As shown, a sewage treatment ultrafiltration device includes a base 1 and a plurality of hollow fiber membranes 111 installed on the base 1. Each of the plurality of hollow fiber membranes 111 is respectively provided with a water inlet 112 and a filtration port 113, and further includes:

[0038] Install component 2. The installation component 2 includes an upper mounting disc 211 and a lower mounting disc 212 arranged on the top surface of the base 1. A plurality of upper arc grooves 213 and lower arc grooves 214 for placing the hollow fiber membranes 111 are respectively formed on the upper mounting disc 211 and the lower mounting disc 212 along their circumferential directions, and the upper arc grooves 213 and the lower arc grooves 214 are correspondingly arranged. A first positioning and fixing component 3 for synchronously positioning the lower ends of the plurality of hollow fiber membranes 111 is provided on the lower mounting disc 212, and a second fixing component 4 for synchronously positioning the upper ends of the plurality of hollow fiber membranes 111 is provided on the upper mounting disc 211. The upper and lower ends of the plurality of hollow fiber membranes are respectively placed into the corresponding upper arc grooves 213 and lower arc grooves 214, and then the first fixing component 3 and the second fixing component 4 are used to perform synchronous positioning operations on the upper and lower ends of the plurality of hollow fiber membranes respectively;

[0039] A grouping component 5 is arranged on the base 1 and divides the plurality of hollow fiber membranes 111 into two independent groups. The grouping component 5 includes a left through shell 511 and a right through shell 512 located at the upper and lower ends of the plurality of hollow fiber membranes 111. The left through shell 511 at the upper and lower ends communicates with the filter ports 113 and the water inlets 112 of the hollow fiber membranes 111 in one group, and the right through shell 512 at the upper and lower ends communicates with the filter ports 113 and the water inlets 112 of the hollow fiber membranes 111 in the other group;

[0040] In order to control the two independent groups of hollow fiber modules, a control component 6 is further provided. The control component 6 includes water inlet pipes 611 respectively arranged on one side of the left through shell 511 and the right through shell 512 at the lower end, and water outlet pipes 612 are arranged on the other side. A three-way pipe 613 is commonly provided on the two water inlet pipes 611, and the other end of the three-way pipe 613 is connected to an external sewage pipe. Adjusting components 7 are respectively arranged between the three-way pipe 613 and the ends of the two water inlet pipes 611. The adjusting components 7 control the opening and closing operations between the two water inlet pipes 611 and the external sewage pipe. Switch valves 614 are respectively arranged on the two water outlet pipes 612. Drain pipes 615 are respectively arranged on one side of the left through shell 511 and the right through shell 512 at the upper end, and backwashing pipes 616 are arranged on the other side. Switch valves 617 and switch valves 618 are respectively arranged on each of the drain pipes 615 and the backwashing pipes 616, and the other end of the switch valve 617 is connected to an external discharge pipe, and the other end of the switch valve 618 is connected to an external flushing pipe.

[0041] With the above structure, under the action of multiple hollow fiber membranes installed in the circumferential direction, the installation area requirement of the multiple hollow fiber membranes can be reduced, so as to meet the use of this device in places with limited space. Then, under the action of the grouping component 5, the control component 6, and the adjustment component 7, the two groups of hollow fiber membrane groups can be in an open state with the three-way pipe 613 at the same time. At this time, the two first switching valves 614 and the third switching valve 618 are in a closed state, and the two second switching valves 617 are in an open state. The external sewage can be conveyed into the two independent hollow fiber membrane groups for filtration treatment, and the filtered water then flows out from the second switching valve 617 into the external discharge pipe and is discharged;

[0042] Or one of the hollow fiber modules can be in an open state and the other hollow fiber group can be in a closed state. At this time, one of the two first switching valves 614 and the third switching valve 618 is in a closed state and the other is in an open state, and one of the two second switching valves 617 is in an open state and the other is in a closed state. In this way, during the process of treating sewage with one group of hollow fiber membranes, the other group of hollow fiber membranes can be backwashed, so that sewage can be continuously treated during the backwashing process, increasing the use efficiency of this device.

[0043] Combined with Fig. Figure 3 、Fig. Figure 4 、Fig. Figure 5 and Fig. Figure 6 As shown, the first fixing component 3 includes two lower positioning seats 311 that are butted around the lower mounting plate 212. A moving rod 315 that is slidably matched with the lower mounting plate 212 is fixedly arranged on the lower positioning seat 311. A cavity 316 is formed in the lower positioning seat 311 corresponding to the moving rod 315. A compression spring 317 is sleeved on the moving rod 315 in the cavity 316. Arc-shaped grooves 312 for positioning multiple hollow fiber membranes 111 are respectively formed at the opposite ends of the two lower positioning seats 311. A bearing seat 313 for supporting multiple hollow fiber membranes 111 is fixedly arranged on the bottom surface of the lower mounting plate 212. Connecting seats 314 are respectively arranged at both ends of the two lower positioning seats 311. The two connecting seats 314 at the same end are fixedly connected through the cooperation of bolts and nuts;

[0044] The second fixing component 4 includes a first hinge seat 411 arranged in the middle of the upper mounting plate 211. Two positioning steel rings 412 located at both ends of the multiple hollow fiber membranes 111 are hinged on the first hinge seat 411. Upper positioning seats 413 are respectively arranged at the other ends of the two positioning steel rings 412. An adjusting member for fixing the two upper positioning seats 413 is arranged on the upper mounting plate 211;

[0045] The adjusting part includes a connecting frame 414 symmetrically arranged with a hinge seat 411, and two upper positioning seats 413 are respectively provided with ratchet teeth 415, and the inclination direction of the ratchet teeth 415 is the same as the swinging direction of the upper positioning seat 413, and a sliding rod 416 is slidably penetrated at the corresponding position of each ratchet tooth 415 on the connecting frame 414, and the two sliding rods 416 are respectively provided with a pawl 417 adapted to the corresponding ratchet teeth 415, and a return spring 418 is sleeved on the sliding rod 416 between the pawl 417 and the inner wall of the connecting frame 414, and a limit seat 419 is respectively provided on the end face of the two sliding rods 416, and a telescopic rod 420 is respectively provided on the two limit seats 419, and the other ends of the two telescopic rods 420 are commonly connected to the pull plate 421, and a connecting rod 422 is provided on the inner end of the pull plate 421, and the connecting rod 422 is connected to the connecting frame 414 by a positioning bolt 423.

[0046] The installation principle of multiple hollow fiber membranes 111 is as follows: first, the positioning steel rings 412 at the two ends of the upper part are swung back to back, and then the hollow fiber membranes 111 are inserted into the position between each lower arc groove 214 and the arc groove body 312 in turn, and the hollow fiber membrane 111 is effectively supported by the supporting seat 313. At the same time, under the reaction force of the compression spring 317, the lower positioning seat 311 is driven to move in the direction of the lower mounting plate 212 to pre-position the hollow fiber membrane 111. Finally, the two connecting seats 314 on the same side are tightened by the cooperation of bolts and nuts, and the lower positioning seats 311 at both ends are fixedly connected to the lower mounting plate 212 to synchronously position the lower ends of the multiple hollow fiber membranes 111.

[0047] Then the positioning steel rings 412 at both ends of the upper part are swung relative to each other into the connecting frame 414, driving the ratchet 415 and pawl 417 on each of them to cooperate. After cooperation, the positioning steel rings 412 at both ends are effectively positioned, thereby synchronously positioning the upper ends of multiple hollow fiber membranes 111. Through the setting of the telescopic rod 420, the positioning steel rings 412 at both ends can be in an asynchronous swinging state without affecting each other. The setting of the pull plate 421 can drive the two sliding rods 416 to move synchronously, so that the two pawls 417 and ratchet 415 are separated at the same time, thereby improving the convenience of releasing the positioning of the positioning steel ring 412.

[0048] Combined with attachment Figure 7 , Attachment Figure 8 and attached Figure 10As shown in the figure, the adjustment component 7 includes a housing 711 with an inverted T-shaped structure respectively arranged between two water inlet pipes 611 and a tee pipe 613. Both ends of the housing 711 are provided with pipe bodies 712 connected to the ends of the water inlet pipes 611 and the tee pipe 613. There is an adjustment distance 713 between the opposite ends of the two pipe bodies 712, and an adjustment component 8 for closing or opening the ends of the two pipe bodies 712 is arranged within this adjustment distance 713. An interlock component 9 is arranged between the opening and closing and the closing and opening actions of the two adjustment components 8, and a control component 10 for keeping the two adjustment components 8 fully open is further arranged on the base 1.

[0049] The working principle of the adjustment component 7 is as follows: when filtering sewage, first, the control component 10 is used to keep the two adjustment components 8 fully open, so that the two water inlet pipes 611 communicate with the tee pipe 613, and the sewage enters the two groups of hollow fiber membrane modules for filtration treatment. When cleaning the hollow fiber membranes, the interlock component 9 is used to keep one adjustment component 8 open and the other adjustment component 8 closed. In this way, during the process of one group of hollow fiber membrane modules treating sewage, the other group of hollow fiber membrane modules can be flushed, so as to continuously filter the sewage.

[0050] Combined with Fig. Figure 8 、Fig. Figure 9 and Fig. Figure 10 As shown, the adjustment component 8 includes two sealing plates 811 slidably arranged within the adjustment distance 713 to seal the ends of the two pipe bodies 712. Wedge-shaped seats 812 are respectively arranged on the opposite ends of the two sealing plates 811. A mating seat 813 is arranged between the two wedge-shaped seats 812 and cooperates with them. A guide rod 814 connected to the mating seat 813 is slidably arranged up and down within the housing 711. In order to ensure the sealing performance between the sealing plate 811 and the pipe body 712, plug heads 825 that can extend into the corresponding pipe bodies 712 are fixedly arranged on the opposite end faces of the two sealing plates 811. The opposite end parts of the two plug heads 825 are provided with inclined surfaces, and mating surfaces adapted to the inclined surfaces are arranged on the inner wall of the end parts of the two pipe bodies 712.

[0051] The bottom surfaces of two wedge-shaped seats 812 are slidably connected to the same base 815. A lifting rod 816 passing through the base 815 is provided on the bottom surface of the mating seat 813. An abutting disc 817 is provided on the bottom surface of the lifting rod 816. Corresponding to each other between the abutting disc 817 and the base 815, there are a first magnet 818 and a second magnet 819 that cooperate with each other. When the first magnet 818 and the second magnet 819 approach each other, they attract each other. In order to ensure the stability of the cooperation between the abutting disc 817 and the base 815, a tapered positioning rod 823 is further provided on the abutting disc 817. A tapered hole 824 for inserting the tapered positioning rod 823 is provided on the base 815. A contact seat 820 is provided on the bottom surface of the base 815. An abutting block 821 that abuts against the contact seat 820 is provided on the bottom wall of the adjusting spacing 713. Springs 822 are provided at the opposite ends of the two sealing plates 811 at the front and rear ends of the wedge-shaped seat 812. The interlocking assembly 9 adjusts the up-and-down and down-and-up movements between the two guide rods 814 in a linkage manner.

[0052] The working principle of the adjustment assembly 8 is that when the adjustment assembly 7 is closed, the guide rod 814 is controlled to move downward, driving the mating seat 813, the abutting disc 817, the base 815, the contact seat 820, the wedge-shaped seat 812, and the sealing plate 811 to move downward synchronously. When the contact seat 820 contacts the abutting block 821, the downward movement of the base 815 and the sealing plate 811 will be blocked at this time, so that the sealing plate 811 completely coincides with the end of the pipe body 712. Then, when the guide rod 814 continues to move downward, the first magnet 818 and the second magnet 819, as well as the tapered positioning rod 823 and the tapered hole 824, will be separated. Then, the mating seat 813 moves downward to cooperate with the wedge-shaped seat 812, and then drives the two sealing plates 811 at both ends to move away from each other, so that the plug 825 extends into the pipe body 712 to effectively seal the pipe bodies 712 at both ends.

[0053] Combined with the attached Figure 7 As shown in the figure, the interlocking assembly 9 includes tooth plates 911 provided at the top ends of the two guide rods 814 with their teeth facing each other. On the base 1, a support frame 912 with an inverted U-shaped structure is provided corresponding to the tooth plates 911. A lifting seat 913 is slidably provided in the support frame 912. A connecting frame 914 is provided on the lifting seat 913 between the two tooth plates 911. A rotating shaft 915 is passed through the connecting frame 914, and a gear 916 that meshes with the two tooth plates 911 together is provided on this rotating shaft 915. And movable rods 917 that are slidably matched with the lifting seat 913 are fixedly provided on the top surfaces of the two tooth plates 911. A positioning assembly 11 for fixing the rotating shaft 915 is provided on the support frame 912. The control assembly 10 is a component provided on the support frame 912 to control the up-and-down sliding of the lifting seat 913. An electric cylinder 1011 is provided on the support frame 912 corresponding to the lifting seat 913, and the movable end of the electric cylinder 1011 is connected to the support frame 912.

[0054] The interlocking component 9 regulates the working principle of the regulating component 10, controls the rotation of the control gear 916, drives the toothed plates 911 at both ends to move up and down for adjustment. When driving one guide rod 814 to move upward, the other guide rod 814 moves downward. Thus, when one adjustment component 8 starts to adjust, the other adjustment component 8 closes for adjustment, improving the operation convenience of the device;

[0055] During the up and down movement of the toothed plates 911 at both ends, when the heights of the two guide rods 814 are the same, the two adjustment components 8 are both in a semi-open state. Then, control the contraction of the electric cylinder 1011 to drive the lifting seat 913 to move upward, and at the same time drive the two guide rods 814 at both ends to move upward, making the two adjustment components 8 in a fully open state.

[0056] Combined with the attached Figure 11 and the attached Figure 12 As shown, the positioning component 11 includes a disk body 1111 arranged on the rotating shaft 915. A frame body 1112 sleeving the disk body 1111 is provided on the support frame 912. On the top wall of the frame body 1112, a second hinge seat 1113 is provided in the middle of the disk body 1111. Two swing seats 1114 with an inverted L-shaped structure and located on both sides of the disk body 1111 are hinged on the second hinge seat 1113. Braking seats 1115 that cooperate with each other and position the disk body 1111 are respectively provided at the opposite ends of the two swing seats 1114. Through the relative or opposite swing of the two braking seats 1115, effective braking or release of braking operations on the disk body 1111 is carried out. Swing rods 1116 are respectively hinged on the bottom surfaces of the two swing seats 1114. The other ends of the two swing rods 1116 are jointly hinged on the adjusting seat 1117. An adjusting screw 1118 that rotates in cooperation with the adjusting seat 1117 is provided on the bottom surface of the frame body 1112 in a threaded manner.
