Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and more specifically, to a membrane device that is easy to assemble. Background Technology

[0002] Membrane filtration is a physical separation method that uses special membrane materials to separate molecules of different sizes and properties. Its working principle is based on the pressure difference between the two sides of the membrane. Through the physical barrier effect of the membrane, the feed flow is divided into two separate flows: permeate and residue. Membrane filtration technology can be divided into microfiltration, ultrafiltration, nanofiltration and reverse osmosis, etc., according to the size of the membrane pores.

[0003] For example, Chinese Patent Publication: A ceramic membrane filtration device system, application number: CN202222352329.7, includes a first ceramic membrane filtration device, a circulation device, and a second ceramic membrane filtration device connected in sequence by pipes; the first ceramic membrane filtration device and the second ceramic membrane filtration device each independently include at least two ceramic membrane filtration units connected in parallel; each ceramic membrane filtration unit includes at least two inlets or at least two outlets; the interior of each ceramic membrane filtration unit is equipped with a nano-scale ceramic membrane filter element. This utility model optimizes and improves the structure of traditional ceramic membrane filtration devices, making them particularly suitable for filtering organic waste liquid containing silicon micropowder, improving solid-liquid separation efficiency, and reducing separation costs.

[0004] However, in the above-mentioned technical solutions, the membrane filtration devices on the market today are roughly divided into plate filtration devices with filter plates and column filtration devices with filter cartridges. In column filtration devices, each time filtration is required, the filter cartridges need to be replaced and installed according to the requirements and collection conditions to complete the assembly of the membrane filtration device. When installing a single filter cartridge, one worker can complete the installation. However, when multiple filter cartridges need to be installed, an additional worker is required to fix the position of the filter cartridges in the cartridge slots when the two filter cartridges are attached. This is not only inconvenient for assembly, but also increases labor costs. Utility Model Content

[0005] The main objective of this invention is to provide a membrane device that is easy to assemble. This effectively addresses the problem that current membrane filtration devices on the market are generally divided into plate filtration devices with filter plates and column filtration devices with filter cartridges. In column filtration devices, each time filtration is required, the filter cartridges need to be replaced and installed according to requirements and collection conditions to complete the assembly of the membrane filtration device. When installing a single filter cartridge, one worker can complete the installation. However, when installing multiple filter cartridges, an additional worker is required to fix the position of the filter cartridges in the cartridge slots when two filter cartridges are attached. This is not only inconvenient for assembly but also increases labor costs.

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

[0007] An easily assembled membrane device includes a base, a filter cartridge slot on the base, a filter cartridge in the filter cartridge slot, a core cover on both sides of the filter cartridge, a plurality of sliding grooves on the core cover, a limit component in the sliding groove, a groove on the side of the core cover away from the filter cartridge, a pull ring slidably disposed in the groove, a plurality of snap-fit ​​grooves on the pull ring, a through groove on the inner wall of the side of the groove near the filter cartridge, a connecting tube movably disposed in the through groove, and a fixed cap on one side of the filter cartridge slot.

[0008] Preferably, the limiting component has a limiting post slidably disposed within the groove, and the limiting post is provided with a first toothed groove.

[0009] Preferably, a first gear is engaged on one side of the first tooth groove, a rotating column is provided on the first gear, and a second gear is provided on the rotating column.

[0010] Preferably, the limiting component has a sliding post slidably disposed on the core cover, and the sliding post is provided with a second toothed groove.

[0011] Preferably, the second gear meshes with the second tooth groove.

[0012] Preferably, the sliding pin is fixedly connected to the pull ring.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) When multiple filter elements need to be bonded together, the present invention first places one filter element into the filter element slot, and then moves the pull ring through the buckle groove. The pull ring moves the sliding column, thereby limiting the filter element in the filter element slot through the limiting column. Then, the other filter element is bonded to the filter element in the filter element slot. At this time, since the filter element in the filter element slot is limited by the limiting column, the filter element in the filter element slot will not move into the filter element slot due to the bonding and squeezing, thus facilitating the bonding of the two filter elements. As the two filter elements are gradually bonded, the pull ring is gradually squeezed back to its original position, thereby allowing the limiting column to return to its original position. The limiting column no longer limits the filter element in the filter element slot. Then, both bonded filter elements can be placed into the filter element slot. Then, the filter element slot is sealed and fixed by the fixed cover. No other staff are required to assist in the assembly, which is convenient for assembly. One staff member can complete the bonding and installation of multiple filter elements, reducing labor costs. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1 and Figure 2 As shown, an easy-to-assemble membrane device includes a base 1, a filter element slot 2 on the base 1, a filter element 3 inside the filter element slot 2, a core cover 4 on both sides of the filter element 3, a plurality of sliding grooves 5 on the core cover 4, a limiting component 6 inside the sliding grooves 5, a groove 7 on the side of the core cover 4 away from the filter element 3, a pull ring 8 slidably disposed in the groove 7, a plurality of fastening grooves 9 on the pull ring 8, a through groove 10 on the inner wall of the side of the groove 7 near the filter element 3, a connecting tube 11 movably disposed in the through groove 10, and a fixed cover 12 on one side of the filter element slot 2.

[0021] like Figure 3 As shown, in another embodiment of the present invention, the limiting component 6 is slidably provided with a limiting post 601 in the sliding groove 5, and the limiting post 601 is provided with a first toothed groove 602.

[0022] A first gear 603 is meshed on one side of the first tooth groove 602, a rotating column 604 is provided on the first gear 603, and a second gear 605 is provided on the rotating column 604;

[0023] The limiting component 6 has a sliding post 606 slidably mounted on the core cover 4. The sliding post 606 has a second toothed groove 607. When two filter elements 3 need to be joined together, the sliding post 606 is first moved by the pull ring 8. The sliding post 606 drives the second gear 605 to rotate through the second toothed groove 607. The second gear 605 drives the rotating post 604 to rotate. The rotating post 604 drives the first gear 603 to rotate. The first gear 603 moves the limiting post 601 out of the sliding groove 5 through the first toothed groove 602. Thus, the limiting post 601 limits the filter element 3 in the filter element slot 2, ensuring that the filter element 3 is in the filter element slot. 2. One end of the filter element 3 cannot enter the filter element slot 2 temporarily. Then, another filter element 3 can be attached to the filter element 3 located in the filter element slot 2. At this time, since the filter element 3 in the filter element slot 2 is limited by the limiting post 601, the filter element 3 located in the filter element slot 2 will not move into the filter element slot 2 due to the pressure of the attachment, thus facilitating the attachment of the two filter elements 3. As the two filter elements 3 are gradually attached, the pull ring 8 is gradually pressed back to its original position, so that the limiting post 601 returns to its original position. The limiting post 601 no longer limits the filter element 3 in the filter element slot 2. Then, both attached filter elements 3 can be placed into the filter element slot 2.

[0024] The working principle of this easy-to-assemble membrane device:

[0025] In use, if it is not necessary to attach two filter elements 3 together, first remove the connecting tube 11 from the through groove 10, then place the filter element 3 with the connecting tube 11 removed into the filter element slot 2, and then seal and fix the filter element slot 2 with the fixing cap 12 to complete the installation. When it is necessary to attach multiple filter elements 3 together, first place one filter element 3 into the filter element slot 2, then move the pull ring 8 through the buckle groove 9, the pull ring 8 moves the sliding column 606, the sliding column 606 drives the second gear 605 to rotate through the second tooth groove 607, the second gear 605 drives the first gear 603 to rotate through the rotating column 604, the first gear 603 moves the limiting column 601 out of the sliding groove 5 through the first tooth groove 602, thereby limiting the filter element 3 in the filter element slot 2 through the limiting column 601, so that the end of the filter element 3 outside the filter element slot 2 cannot enter the filter element slot temporarily. 2. Then, pick up another filter element 3 and attach it to the filter element 3 located in the filter element slot 2. At this time, because the filter element 3 in the filter element slot 2 is limited by the limiting post 601, the filter element 3 in the filter element slot 2 will not move into the filter element slot 2 due to the pressing during attachment, thus facilitating the attachment of the two filter elements 3. As the two filter elements 3 are gradually attached, the pull ring 8 is gradually pressed back to its original position, so that the limiting post 601 returns to its original position. The limiting post 601 no longer limits the filter element 3 in the filter element slot 2. Then, both attached filter elements 3 can be placed into the filter element slot 2. Then, repeat the above steps to attach multiple filter elements 3. Then, the filter element slot 2 is sealed and fixed by the fixing cover 12. No other staff are required to assist in the assembly, which is convenient for assembly. One staff member can complete the attachment and installation of multiple filter elements 3, reducing labor costs.

[0026] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
