Description

Technical Field

[0001] This utility model relates to the field of multi-bag anti-corrosion filter technology, and in particular to a new type of filter bag pressing mechanism for a multi-bag machine. Background Technology

[0002] Multi-bag filters are key equipment used for liquid filtration and separation in industries such as chemical, pharmaceutical, and food processing. One of their core functions is to intercept solid particles through filter bags. In highly corrosive media environments, the corrosion resistance of each component of the equipment is crucial.

[0003] In existing technologies, multi-bag filters typically use metal clamping rings to secure the filter bags. While these metal clamping rings are simple in structure, they are prone to chemical corrosion in corrosive environments such as hydrochloric acid and strong alkalis. This not only leads to their own damage and failure but can also contaminate the filtrate and shorten the equipment's lifespan. Furthermore, traditional clamping structures often involve clamping each filter bag individually, which is cumbersome, inefficient, and makes it difficult to ensure uniform clamping force across all bags. This can easily result in short circuits or leaks caused by incomplete sealing of individual bags. Therefore, existing technologies have the following significant drawbacks: first, the metal clamping rings have poor corrosion resistance, limiting the application of the equipment in corrosive environments; second, the clamping of multiple filter bags is asynchronous and uneven, affecting overall sealing reliability and operational efficiency; and third, there is a lack of an integrated clamping mechanism that can simultaneously address corrosion resistance, synchronized clamping, and reliable sealing. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of filter bag pressing mechanism for multi-bag machines, which has the effects of uniform pressing, reliable sealing and efficient filtration.

[0005] The above-mentioned utility model objective is achieved through the following technical solution:

[0006] A novel filter bag pressing mechanism for a multi-bag machine includes a filter bag pressing ring, a filter bag perforated plate, a perforated fixing plate, and fasteners.

[0007] The filter bag porous plate has multiple first mounting holes; a support basket is placed in each first mounting hole, and the support basket is used to place the filter bag.

[0008] The port of each of the support baskets is engaged with the filter bag pressure ring;

[0009] The porous fixing plate is provided with a second mounting hole corresponding to the first mounting hole, and the porous fixing plate is placed above the multiple filter bag pressure rings;

[0010] The filter bag porous plate and the porous fixing plate are fixedly connected by multiple sets of fasteners.

[0011] The above technical solution establishes the core function of filter bag pressing in a multi-bag machine. Specifically, the first mounting hole of the filter bag perforated plate enables the support basket to be arranged in a regular manner. The filter bag pressing ring and the basket are engaged to initially fix the filter bag. Then, the perforated fixing plate and the filter bag perforated plate are locked with fasteners, ultimately achieving independent and synchronous pressing of multiple filter bags. This avoids filter bag displacement and affects the filtration effect. Furthermore, the corresponding hole design reduces assembly difficulty and ensures stable operation of the mechanism.

[0012] As a further technical solution of this utility model: the filter bag pressure ring is a three-section stepped structure, wherein the diameter of the middle section is larger than the diameter of the upper and lower sections.

[0013] Through the above technical solution, the three-section stepped structure of the filter bag pressure ring can be adapted to the matching requirements of different components; the large diameter of the middle section provides sufficient pressing surface, while the small diameters of the upper and lower sections are precisely matched with the porous fixing plate and the support basket, respectively, thus ensuring the reliability of filter bag pressing and component matching from a structural perspective.

[0014] As a further technical solution of this utility model: the inner ring of the port of the supporting basket is adapted to the lower section of the filter bag pressure ring, and the edge of the port of the supporting basket abuts against the middle section of the filter bag pressure ring for pressing the filter bag.

[0015] The above technical solution supports the inner ring of the support basket port and the lower section of the filter bag pressure ring to prevent lateral displacement of the pressure ring. The edge of the port abuts against the middle section of the pressure ring, so that the filter bag fits against the inner wall of the basket, effectively preventing the filtered liquid from leaking from the gaps and improving the filtration sealing performance.

[0016] As a further technical solution of this utility model: the upper section of the filter bag pressure ring passes through the second mounting hole.

[0017] Through the above technical solution, the upper section of the filter bag pressure ring passes through the second mounting hole of the multi-hole fixing plate, which plays a positioning and guiding role, preventing the filter bag pressure ring from shifting when under pressure, ensuring that the clamping force below is transmitted vertically and evenly to the filter bag, and improving the stability of the entire mechanism.

[0018] As a further technical solution of this utility model: the fastener includes a corrosion-resistant bolt and a corrosion-resistant nut; the corrosion-resistant bolt passes through the filter bag porous plate and the porous fixing plate in sequence, and is then locked and fixed with the corrosion-resistant nut.

[0019] Through the above technical solution, the fastener composed of corrosion-resistant bolts and nuts can not only achieve a rigid connection between the filter bag porous plate and the fixed pressure plate and stably transmit the clamping force, but also adapt to the corrosive environment to extend the service life and prevent connection failure and filter bag clamping failure caused by corrosion.

[0020] As a further technical solution of this utility model: a sealing ring is provided on the side of the port of the supporting basket.

[0021] Through the above technical solution, a sealing ring is set on the side of the port of the support basket, which forms an auxiliary side seal with the filter bag pressure ring. Together with the end face compression seal, it forms a multi-layer sealing barrier, which greatly improves the sealing reliability and completely prevents the leakage of impurity media from the compression gap.

[0022] In summary, this utility model has at least one of the following beneficial technical effects:

[0023] 1. This utility model discloses a new type of filter bag pressing mechanism for a multi-bag machine. Through the first mounting hole of the filter bag perforated plate supporting the support basket, the filter bag pressing ring engaging with the support basket, and the fastener locking the multi-hole fixing plate and the filter bag perforated plate, multiple filter bags are pressed independently and synchronously, avoiding filter bag displacement that affects the filtration effect. At the same time, the corresponding hole positions reduce the assembly difficulty and ensure stable operation of the mechanism.

[0024] 2. This utility model discloses a new type of filter bag pressing mechanism for a multi-bag machine. Through the differentiated design of the three-section stepped structure of the filter bag pressing ring (the diameter of the middle section is larger than that of the upper and lower sections), it achieves precise adaptation with the multi-hole fixed pressing plate and the support basket. This provides sufficient contact surface for filter bag pressing and ensures the reliability of component matching. At the same time, the positioning guide through the second mounting hole in the upper section ensures that the pressing force is transmitted vertically and evenly.

[0025] 3. This utility model discloses a new type of filter bag pressing mechanism for a multi-bag machine. Through the design of a sealing ring on the side of the support basket port, combined with the pressing of the filter bag pressure ring and the end face of the support basket, multiple protections of side sealing and end face sealing are achieved, which completely prevents impurities from leaking from the pressing gap and improves the reliability of sealing. At the same time, the rigid connection of corrosion-resistant bolts and nuts achieves stable transmission of pressing force, adapting to corrosive environments and extending the service life of the mechanism.

[0037] Example 1:

[0038] Reference Figure 1 This utility model discloses a novel filter bag pressing mechanism for a multi-bag machine, comprising a filter bag pressing ring 4, a filter bag perforated plate 5, a perforated fixing plate 7, and fasteners. (Refer to...) Figure 3The filter bag porous plate 5 has multiple first mounting holes 51, and each first mounting hole 51 contains a support basket 6 for supporting the filter bag. (Refer to...) Figure 7 The support basket 6 is a cylindrical structure with an open top and mesh holes all around. The bottom is arc-shaped. Stable installation is achieved by adapting the shape of the first mounting hole 51. This multi-hole distribution design enables the support basket 6 to be arranged in a regular manner, providing a basis for multiple filter bags to work independently.

[0039] Each support basket 6 is connected to the filter bag pressure ring 4 via a snap-fit ​​connection to ensure the stability of their initial positioning. (Refer to...) Figure 5 and 6 The filter bag pressure ring 4 is designed with a three-section stepped structure. Its structural feature is that the diameter of the middle section is larger than that of the upper and lower sections. This differentiated structure allows the filter bag pressure ring 4 to accurately adapt to the assembly requirements of different components. The inner ring of the port of the support basket 6 is adapted to the lower section of the filter bag pressure ring 4, while the edge of the port of the support basket 6 abuts against the middle section of the filter bag pressure ring 4. Through this dual cooperation, the middle section of the filter bag pressure ring 4 can apply uniform pressure to the edge of the filter bag, so as to achieve a tight fit between the filter bag and the inner wall of the support basket 6.

[0040] Reference Figure 3 and Figure 4 The multi-hole fixing plate 7 has a second mounting hole 71 that corresponds one-to-one with the first mounting hole 51. After the upper section of the filter bag pressure ring 4 passes through the second mounting hole 71, the multi-hole fixing plate 7 is placed above the multiple filter bag pressure rings 4. The second mounting hole 71 forms an axial limit and guide for the filter bag pressure ring 4 to prevent it from shifting when under pressure.

[0041] Reference Figure 1 The filter bag clamping mechanism is equipped with multiple sets of fastening components, each set including a corrosion-resistant bolt 8 and a matching corrosion-resistant nut 9. (Refer to...) Figure 3 and Figure 4 The filter bag perforated plate 5 and the perforated fixing plate 7 are both provided with through holes for the corrosion-resistant bolts 8 to pass through. After the corrosion-resistant bolts 8 pass through the through holes on the perforated fixing plate 7 and the filter bag perforated plate 5 in sequence, they are locked and fixed with the corrosion-resistant nuts 9 to achieve a rigid connection between the two and ensure stable transmission of the clamping force.

[0042] To further improve sealing performance, a sealing ring is provided on the side of the port of the support basket 6. This sealing ring, together with the filter bag pressure ring 4 and the filter bag perforated plate 5, forms a multi-layer sealing structure to completely block the liquid leakage channel.

[0043] The installation process of the filter bag pressing mechanism of this utility model is as follows: Refer to Figure 1 and Figure 2First, the perforated filter bag plate 5 is installed in the middle of the lower cylinder 1 and the upper cylinder 2 to establish the basic load-bearing structure of the filter bag pressing mechanism. Then, a support basket 6 is placed in each mounting hole of the perforated filter bag plate 5, and a sealing ring is installed on its annular side to achieve side sealing and prevent liquid leakage. The bottom arc of the support basket 6 fits against the inner wall of the first mounting hole 51, completing the initial positioning. Then, the filter bag is placed inside the support basket 6, so that the edge of the filter bag port flat covers the annular opening of the support basket 6. Finally, the side of the filter bag pressing ring 4 is tightly fitted with the inner diameter of the annular opening of the support basket 6 and then gradually... Each filter bag in each support basket 6 is pressed tightly, ensuring that the number of filter bag pressing rings 4 corresponds one-to-one with the number of support baskets 6. After all filter bags and filter bag pressing rings 4 are installed, the perforated fixing plate 7 is pressed on top of the multiple filter bag pressing rings 4, and the upper part of the filter bag pressing ring 4 is inserted into the corresponding mounting hole of the perforated fixing plate 7. Finally, the corrosion-resistant bolts 8 are screwed into the threaded holes of the perforated plate 5 of the filter bag and passed through the perforated fixing plate 7, and then the corrosion-resistant nuts 9 are tightened. Then, the upper cover 3 is placed on the top of the upper cylinder 2. At this point, the installation of the filter bag pressing device and the equipment closing operation are all completed.

[0044] The implementation principle of this utility model is as follows: the porous fixed pressure plate 7 serves as the overall clamping element, and the locking force provided by the fasteners enables synchronous pressing of all filter bag pressure rings 4, ensuring uniform distribution of clamping force; in the three-section stepped structure of the filter bag pressure ring 4, the middle section serves as the clamping part, providing sufficient clamping area, the lower section serves as the engaging part, cooperating with the inner ring of the support basket 6 port for positioning, and the upper section serves as the positioning part, passing through the second mounting hole 71 of the porous fixed pressure plate 7 to prevent pressure deviation; the edge of the support basket 6 port abuts against the middle section of the filter bag pressure ring 4 to form an end face seal, while the sealing ring set on the side of the port forms a side seal with the filter bag pressure ring 4, constituting a multi-layer sealing barrier; all core components are made of non-metallic anti-corrosion materials suitable for the working conditions, combined with corrosion-resistant bolts 8 and corrosion-resistant nuts 9, ensuring long-term stable operation of the mechanism in corrosive media. Through the above structural design and cooperation, the efficient, reliable, and corrosion-resistant synchronous clamping function of multiple filter bags is achieved.

[0045] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
