Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically to a water treatment ultrafiltration membrane filtration device. Background Technology

[0002] Water plants, sewage treatment plants, chemical plants, and other facilities require water quality process analysis instruments. However, water contains a large number of suspended particles, and directly using water to analyze these instruments can easily cause clogging and damage. Ultrafiltration membranes are semi-permeable polymer membranes used in ultrafiltration processes to separate high-molecular-weight colloids or suspended particles of a certain size from a solution. Their retention mechanism mainly includes the sieving effect and electrostatic effect of the membrane. The filter medium is the ultrafiltration membrane. Driven by the pressure difference on both sides, only low-molecular-weight solutes and water can pass through the ultrafiltration membrane, thereby achieving the purpose of purification, separation, and concentration. Therefore, the ultrafiltration process of ultrafiltration membranes is essentially a mechanical sieving process.

[0003] Traditional filtration devices are complex to install and replace, and when ultrafiltration membranes need to be replaced, the filtration device must be shut down to stop filtration, which affects working efficiency. Therefore, a water treatment ultrafiltration membrane filtration device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a water treatment ultrafiltration membrane filtration device that solves the problems of complex installation and replacement processes of traditional filtration devices in the prior art, and the need to shut down the filtration device to stop filtration when the ultrafiltration membrane needs to be replaced, which affects working efficiency.

[0005] This utility model provides the following technical solution: a water treatment ultrafiltration membrane filtration device, including a main pipe, an adapter fixedly connected to the side end of the main pipe, valves fixedly connected to the left and right sides of the adapter, a connecting pipe fixedly installed on the side end of each valve, an installation box fixedly connected to the side end of each connecting pipe, an outlet pipe fixedly connected to the right side end of each installation box, a rotating assembly inside each installation box, a clamping assembly at the outer end of each rotating assembly, and an ultrafiltration membrane between the inner sides of each clamping assembly.

[0006] As a preferred embodiment of the above technical solution, a bracket is fixedly connected to the bottom of the mounting box, an arc-shaped groove is provided at the top of the bracket, and a T-shaped sliding groove is provided at the bottom of the mounting box.

[0007] As a preferred embodiment of the above technical solution, the rotating assembly includes a bidirectional threaded rod, which is rotatably disposed between the left and right sides of the mounting box from the outside to the inside. The middle part of the bidirectional threaded rod is rotatably disposed within the bracket, and a knob is fixedly connected to the side end of the bidirectional threaded rod.

[0008] As a preferred embodiment of the above technical solution, the clamping assembly includes two sets of movable plates, each set of movable plates having an insertion port on its side, and each set of movable plates having a telescopic water pipe fixedly connected to its side, with each telescopic water pipe being fixedly connected to the left and right ends inside the mounting box.

[0009] As a preferred embodiment of the above technical solution, the telescopic water pipe on the left end is connected to the connecting pipe, the telescopic water pipe on the right end is connected to the outlet pipe, and a positioning hole is provided on the side end of each of the moving plates.

[0010] As a preferred embodiment of the above technical solution, each of the movable plates is fixedly connected to a T-shaped slider at its bottom end, and each slider is slidably connected within a groove.

[0011] As a preferred embodiment of the above technical solution, the ultrafiltration membrane is fixedly connected to two side ends with insertion tubes, and each insertion tube is fixedly connected to a limiting plate at its outer end. Each limiting plate has the same insertion port through its side end.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention facilitates the installation of ultrafiltration membranes through the design of a rotating component and a clamping component. The insertion tube at the side of the ultrafiltration membrane is easily connected to the water source (i.e., the port). The installation process is simple, quick, and easy to operate. With two sets of valves, when the ultrafiltration membrane needs to be disassembled, closing either valve allows the other connecting pipe and the ultrafiltration membrane to continue treating the water source. At this point, opening the installation box at the closed valve end allows the rotating component to loosen the clamping component, facilitating membrane disassembly. Therefore, when the ultrafiltration membrane needs replacement, there is no need to shut down the filtration device, avoiding any impact on work efficiency. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a water treatment ultrafiltration membrane filtration device, including a main pipe 1, an adapter 101 fixedly connected to one side of the main pipe 1, valves 103 fixedly connected to both sides of the adapter 101, a connecting pipe 102 fixedly installed to the side of each valve 103, an installation box 2 fixedly connected to the side of each connecting pipe 102, a bracket 202 fixedly connected to the bottom of the installation box 2, an arc groove 203 opened at the top of the bracket 202, a T-shaped sliding groove 201 opened at the bottom of the installation box 2, an outlet pipe 104 fixedly connected to the right side of each installation box 2, a rotating assembly 3 provided inside each installation box 2, a clamping assembly 4 provided at the outer end of each rotating assembly 3, an ultrafiltration membrane 5 provided between the inner sides of each clamping assembly 4, and insertion tubes 501 fixedly connected to both sides of the ultrafiltration membrane 5. Each insertion tube 501 has a fixed connection to a limiting plate 502 at its outer end. Each limiting plate 502 has a through-hole 404 on its side end. The installation of the ultrafiltration membrane 5 is facilitated by the rotation component 3 and the clamping component 4. The insertion tube 501 on the side end of the ultrafiltration membrane 5 can be easily inserted into the position that is connected to the water source (i.e., the clamping component 4). The installation process is simple, quick and easy to operate. With the setting of two sets of valves 103, when it is necessary to disassemble the ultrafiltration membrane 5, the other connecting tube 102 and the ultrafiltration membrane 5 can still achieve water treatment of the water source after closing any one of the valves 103. At this time, by opening the installation box 2 at the end where the valve 103 is closed, the clamping component 4 can be driven to release the ultrafiltration membrane 5 by operating the rotation component 3, thereby facilitating the disassembly of the ultrafiltration membrane 5. Therefore, when the ultrafiltration membrane 5 needs to be replaced, it is not necessary to shut down the filtration device to stop filtration, thus avoiding affecting the working efficiency.

[0021] As one implementation method in this embodiment, such as Figure 2 , Figure 3 and Figure 4As shown, the rotating assembly 3 includes a bidirectional threaded rod 301, which is rotatably disposed between the left and right sides of the mounting box 2 from the outside to the inside. The middle part of the bidirectional threaded rod 301 is rotatably disposed within the bracket 202. A knob 302 is fixedly connected to the side end of the bidirectional threaded rod 301. The clamping assembly 4 includes two sets of moving plates 401, each set of moving plates 401 having an insertion port 404 on its side end. A telescopic water pipe 403 is fixedly connected to the side end of each set of moving plates 401. Each telescopic water pipe 403 is fixedly connected to... The left and right ends are connected inside the mounting box 2. The telescopic water pipe 403 on the left end is connected to the connecting pipe 102, and the telescopic water pipe 403 on the right end is connected to the outlet pipe 104. Each moving plate 401 has a positioning hole 405 on its side end. Each moving plate 401 has a T-shaped slider 402 fixedly connected to its bottom end. Each slider 402 is slidably connected in the slide groove 201. The slider 402 can limit the moving plate 401, so that the moving plate 401 can move horizontally along the outer end of the bidirectional threaded rod 301.

[0022] During implementation, when the ultrafiltration membrane 5 needs to be installed, it is first placed in the arc-shaped groove 203 at the top of the support 202 to provide initial support, aligning the two insertion tubes 501 on the side of the ultrafiltration membrane 5 with the insertion ports 404 of the moving plate 401. Then, by rotating the knob 302, the bidirectional threaded rod 301 can be rotated. Since the slider 402 is slidably connected in the groove 201, the slider 402 can limit the moving plate 401. Therefore, after the bidirectional threaded rod 301 rotates, it can drive the two sets of moving plates 401 to move closer to each other, thus facilitating the movement of the insertion ports 404 on the side of the two sets of moving plates 401 toward the side of each insertion tube 501. When each moving plate 401 moves to the insertion port 404, the limiting plate 502 is in contact with the side of the moving plate 401. At this time, the ultrafiltration membrane can be adjusted by slightly rotating it. After step 5, the positioning hole 405 on the side of the limiting plate 502 is aligned with the positioning hole 405 on the side of the moving plate 401. Then, the two sets of positioning holes 405 are threaded together by bolts, which facilitates the fixing and installation between the moving plate 401 and the limiting plate 502. When it is necessary to disassemble the ultrafiltration membrane 5, after closing any one of the valves 103, the other connecting pipe 102 and the ultrafiltration membrane 5 can still achieve water treatment of the water source. At this time, by opening the installation box 2 at the end where the valve 103 is closed, and by unscrewing the bolt between the moving plate 401 and the limiting plate 502, the double-threaded rod 301 is rotated by turning the knob 302. The double-threaded rod 301 can drive the two sets of moving plates 401 to move away from each other. At this time, the insertion tube 501 on the side of the ultrafiltration membrane 5 will be disengaged from the insertion port 404 on the side of the moving plate 401, which facilitates the disassembly of the ultrafiltration membrane 5.

[0023] Working principle: After opening the two valves 103, water enters each connecting pipe 102 from the main pipe 1. Then, the water in the connecting pipe 102 enters the ultrafiltration membrane 5 through the telescopic water pipe 403 for water treatment and filtration. The treated water is then transported out from the outlet pipe 104. When installing the ultrafiltration membrane 5, it is first placed in the arc-shaped groove 203 at the top of the support 202 to provide initial support, so that the two insertion tubes 501 on the side of the ultrafiltration membrane 5 are aligned with the insertion ports 404 of the moving plate 401. Then, by turning the knob 302, the bidirectional threaded rod 301 can be rotated. Since the slider 402 is slidably connected in the groove 201, the slider 402 can limit the movement of the moving plate 401. Therefore, after the bidirectional threaded rod 301 rotates, it can drive the two sets of moving plates 401 to move closer to each other, thereby facilitating the insertion ports 404 on the side of the two sets of moving plates 401. 4. Move towards the side end of each insertion tube 501. When each moving plate 401 moves to the insertion tube 501 and inserts into the insertion port 404, the limiting plate 502 is attached to the side end of the moving plate 401. At this time, after slightly rotating and adjusting the ultrafiltration membrane 5, the positioning hole 405 on the side end of the limiting plate 502 is aligned with the positioning hole 405 on the side end of the moving plate 401. Then, the two sets of positioning holes 405 are threaded together by bolts, which facilitates the fixing and installation between the moving plate 401 and the limiting plate 502. The moving plate 401 and the limiting plate 502 can be sealed by setting existing sealing parts (such as sealing rings) to prevent water leakage. Therefore, it is convenient to install the ultrafiltration membrane 5, so that the insertion tube 501 on the side end of the ultrafiltration membrane 5 can be easily inserted into the position (i.e., insertion port 404) that is connected to the water source. The installation process is simple, quick and easy to operate.

[0024] When it is necessary to disassemble the ultrafiltration membrane 5, after closing any one of the valves 103, the other connecting pipe 102 and the ultrafiltration membrane 5 can still treat the water source. At this time, by opening the installation box 2 at the end where the valve 103 is closed, and by unscrewing the bolts between the moving plate 401 and the limiting plate 502, the double-threaded rod 301 can be rotated by turning the knob 302. The double-threaded rod 301 can drive the two sets of moving plates 401 to move away from each other. At this time, the insertion tube 501 on the side of the ultrafiltration membrane 5 will be disengaged from the insertion port 404 on the side of the moving plate 401, which makes it easy to disassemble the ultrafiltration membrane 5. Therefore, when the ultrafiltration membrane 5 needs to be replaced, there is no need to shut down the filtration device to stop filtration, thus avoiding affecting the working efficiency.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
