Description

Technical Field

[0001] This utility model relates to the field of ultrafiltration device technology, and in particular to an ultrafiltration device with adjustable membrane module spacing. Background Technology

[0002] Ultrafiltration technology, as a highly efficient separation technology, has been widely used in water treatment, biopharmaceuticals, food processing and other fields. The core component of an ultrafiltration device is the membrane module, whose performance directly affects the ultrafiltration efficiency, processing capacity and service life.

[0003] Membrane modules are typically composed of multiple membrane elements arranged at a certain spacing. The proper setting of the membrane spacing is crucial for fluid distribution, pollutant retention, and membrane fouling control. During the production process, the properties of the feed liquid or process requirements may change. A fixed membrane spacing cannot enable the system to adapt to these changes quickly, which may lead to a decrease in filtration performance and affect production efficiency and product quality.

[0004] In some existing technologies, the membrane module spacing of most ultrafiltration devices is fixed during use. Ultrafiltration systems with fixed membrane spacing are difficult to adapt to different types and concentrations of feed liquids, and may require replacement of membrane modules or equipment modification, which reduces the versatility and economy of the system. Furthermore, when the membrane modules need cleaning or maintenance, the fixed membrane spacing may not be conducive to the flow of cleaning liquid and the discharge of dirt. Moreover, when adjusting the membrane spacing, it is not easy to intuitively observe the adjusted spacing value. Utility Model Content

[0005] The main objective of this invention is to provide an ultrafiltration device with flexibly adjustable membrane module spacing. This effectively solves the problem that in most existing technologies, the membrane module spacing of ultrafiltration devices is fixed during use. Ultrafiltration systems with fixed membrane spacing are difficult to adapt to different types and concentrations of feed liquids, and may require replacement of membrane modules or equipment modification, which reduces the versatility and economy of the system. Furthermore, when the membrane modules need cleaning or maintenance, the fixed membrane spacing may hinder the flow of cleaning solution and the discharge of dirt. Also, when adjusting the membrane spacing, it is not easy to intuitively observe the adjusted spacing value.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An ultrafiltration device with adjustable membrane module spacing includes a connecting pipe, on the outer surface of which ultrafiltration pipes are symmetrically fixedly connected front and rear. Ultrafiltration mechanisms are installed on the inner surfaces of the connecting pipe and the two ultrafiltration pipes. Adjustment mechanisms are symmetrically installed on opposite sides of the two ultrafiltration mechanisms located at the front and rear ends.

[0008] Preferably, all three ultrafiltration mechanisms include an ultrafiltration membrane, and a sealing ring is fixedly connected to the outer surface of the ultrafiltration membrane.

[0009] Preferably, the sealing ring has an internal mounting groove, through which it engages with the sealing ring.

[0010] Preferably, all three sealing rings are slidably connected to the inner side of the connecting pipe and the ultrafiltration pipe.

[0011] Preferably, mounting blocks are symmetrically fixedly connected to opposite sides of the two ultrafiltration membranes located at the front and rear ends, and adjusting rods are fixedly connected to opposite sides of the two mounting blocks located on the same side.

[0012] Preferably, the two adjusting rods located at the same end are symmetrically fixedly connected to sliders on opposite sides, and a number of sliders located on the same side of the same end are slidably connected to locking blocks on their outer surfaces, and the two adjusting rods located on the same side are fixedly connected to levers on opposite ends.

[0013] Preferably, the opposite sides of the two locking blocks located at the same end are fixedly connected with limiting rods, and the outer surfaces of the opposite sides of the two limiting rods located at the same end are slidably connected with sliding sleeves. The outer sides of the limiting rods and sliding sleeves located at the same end and on the same side are slidably connected with springs.

[0014] Preferably, the two ultrafiltration pipes are symmetrically equipped with scale markings on the left and right sides near the adjustment mechanism.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the implementation of this utility model, by setting an adjustment mechanism, it is found that the membrane module spacing of most ultrafiltration devices is fixed during use. Ultrafiltration systems with fixed membrane spacing are difficult to adapt to different types and concentrations of feed liquids. Therefore, by installing an adjustment mechanism on the opposite side of the front and rear ultrafiltration mechanisms, the adjustment rod is slidably connected to the locking block through a slider. This allows for adjustment of the spacing between the front and rear ultrafiltration mechanisms and the intermediate ultrafiltration mechanism. By adjusting the membrane module spacing, the flow rate and flow state of the feed liquid on the membrane surface can be better controlled, resulting in a more uniform flow distribution. Furthermore, the membrane spacing can be flexibly adjusted according to the different viscosities, particle sizes, and concentrations of different feed liquids. For example, for high-viscosity or high-turbidity feed liquids, the spacing can be appropriately increased to reduce flow resistance and prevent membrane clogging.

[0017] 2. In the implementation of this utility model, by setting a scale, it is not convenient to intuitively observe the adjusted spacing value when the membrane spacing is adjusted. Therefore, by setting a scale composed of multiple scale lines, when the ultrafiltration mechanism is adjusted by the adjustment mechanism, the movement of the ultrafiltration mechanism covers the corresponding scale, and the distance between the current end ultrafiltration mechanism and the middle ultrafiltration mechanism can be known by the number of scale lines that are exposed.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Example 1

[0028] like Figure 1As shown, an ultrafiltration device with adjustable membrane module spacing includes a connecting pipe 1, ultrafiltration pipes 2 are symmetrically fixedly connected to the outer surface of the connecting pipe 1, and ultrafiltration mechanisms 7 are installed on the inner surfaces of the connecting pipe 1 and the two ultrafiltration pipes 2. Adjustment mechanisms 5 are symmetrically installed on opposite sides of the two ultrafiltration mechanisms 7 located at the front and rear ends.

[0029] In this embodiment, the ultrafiltration membrane 701 is snapped into the mounting groove 704 inside the sealing ring 703 by a snap-fit ​​connection. The sealing ring 703 has a certain degree of flexibility. Then, the assembled ultrafiltration mechanism 7 is installed from the inside of the front and rear ultrafiltration pipes 2 respectively. The mounting block 501 is fixed on the side of the ultrafiltration membrane 701 away from the middle ultrafiltration mechanism 7. Then, the sliding sleeve 508 is installed on the inner wall of the ultrafiltration pipe 2 accordingly.

[0030] When adjusting the distance between the ultrafiltration mechanisms 7 at both ends and the middle ultrafiltration mechanism 7, hold the lever 506 and push it inward or pull it outward to shorten or lengthen the distance between the ultrafiltration mechanism 7 at both ends and the middle ultrafiltration mechanism 7.

[0031] During adjustment, the adjusting rod 502 slides inside the limiting bracket 505. When the adjusting rod 502 is moved, the locking block 504 is pressed by the slider 503 and moves towards the side closer to the inner wall of the ultrafiltration pipe 2. The spring 509 is compressed under the movement of the locking block 504. When the adjusting rod 502 stops moving, the locking block 504 loses the pressure of the slider 503. Under the action of the spring 509's own elasticity, the spring 509 rebounds, causing the locking block 504 to rebound to its original position, thus engaging and connecting between the two sliders 503 to achieve the limiting effect of the sliders 503, thereby limiting and fixing the position of the adjusted ultrafiltration mechanism 7. The overall operation is simple and convenient.

[0032] When the end ultrafiltration mechanism 7 moves away from the middle ultrafiltration mechanism 7, the scale mark 6 is covered as the ultrafiltration mechanism 7 moves. The distance between the current ultrafiltration mechanism 7 and the middle ultrafiltration mechanism 7 can be known by the number of exposed scale marks 6.

[0033] The connection of threaded ring 3 and threaded sleeve 4 facilitates the assembly and disassembly of the entire ultrafiltration unit.

[0034] For details, please refer to Figure 2 and Figure 3 In this embodiment, each of the three ultrafiltration mechanisms 7 includes an ultrafiltration membrane 701. The outer surface of the ultrafiltration membrane 701 is fixedly connected to a 702. The outer surface of the 702 is engaged with a sealing ring 703. The sealing ring 703 has an installation groove 704 inside. The 702 is engaged with the sealing ring 703 through the installation groove 704. All three sealing rings 703 are slidably connected to the inner side of the connecting pipe 1 and the ultrafiltration pipe 2.

[0035] Further reference Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, mounting blocks 501 are symmetrically fixedly connected to opposite sides of the two ultrafiltration membranes 701 located at the front and rear ends. Adjusting rods 502 are fixedly connected to opposite sides of the two mounting blocks 501 located on the same side. Slider blocks 503 are symmetrically fixedly connected to opposite sides of the two adjusting rods 502 located at the same end. A locking block 504 is slidably connected to the outer surfaces of several sliders 503 located at the same end and on the same side. A lever 506 is fixedly connected to opposite ends of the two adjusting rods 502 located on the same side.

[0036] Further reference Figure 1 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the opposite sides of the two locking blocks 504 located at the same end are fixedly connected to limiting rods 507, and the outer surfaces of the opposite sides of the two limiting rods 507 located at the same end are slidably connected to sliding sleeves 508. The outer sides of the limiting rods 507 and sliding sleeves 508 located at the same end and on the same side are slidably connected to springs 509.

[0037] By installing an adjustment mechanism 5 on the opposite side of the front and rear ultrafiltration units 7, the adjustment rod 502 is slidably connected to the locking block 504 via the slider 503. This allows for adjustment of the distance between the front and rear ultrafiltration units 7 and the intermediate ultrafiltration unit 7. By adjusting the membrane module spacing, the flow rate and flow state of the feed liquid on the membrane surface can be better controlled, resulting in a more uniform flow distribution. Furthermore, the membrane spacing can be flexibly adjusted according to the different viscosities, particle sizes, and concentrations of different feed liquids. For example, for high-viscosity or high-turbidity feed liquids, the spacing can be appropriately increased to reduce flow resistance and prevent membrane clogging.

[0038] Example 2

[0039] This embodiment adds a scale 6 to the first embodiment to intuitively display the adjustment values ​​of the ultrafiltration mechanism 7 located at the front and rear ends. By setting the scale 6, the adjustment distance value of the ultrafiltration mechanism 7 can be seen intuitively.

[0040] Specifically, referring to 1, in this embodiment, the two ultrafiltration pipes 2 are symmetrically provided with scales 6 on the left and right sides near the adjustment mechanism 5.

[0041] By setting the scale 6, which consists of multiple scale lines, when the ultrafiltration mechanism 7 is adjusted by the adjustment mechanism 5, the movement of the ultrafiltration mechanism 7 covers the corresponding scale 6. The distance between the current end ultrafiltration mechanism 7 and the middle ultrafiltration mechanism 7 can be known by the number of scale 6 that are exposed.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
