Description

Technical Field

[0001] This application relates to the field of filtration devices, and in particular to a quick-installation gusseted bag. Background Technology

[0002] With economic development, industries such as laser processing, magnesium and aluminum processing, plastics, organic synthesis, powder metallurgy, and food processing are also constantly progressing. The development of these industries has led to a dramatic increase in the types and amounts of dust used. Furthermore, the trend towards automation and continuous operation in production processes has significantly increased the potential danger of dust explosions. Dust explosions not only cause severe damage to production equipment but also threaten the lives of operators; therefore, preventing dust explosions is of paramount importance. Against this backdrop, the requirements for dust control and safety protection in related production processes are increasingly stringent. To prevent dust explosion accidents, factories or workshops that generate combustible dust typically use dust removal equipment to filter dust from the air, reducing the concentration of combustible dust in the air to well below the lower explosive limit.

[0003] Currently, dust collection equipment on the market typically employs the following filtration methods: One method involves directly fitting filter bags, requiring different filter bag materials to be combined in a specific order and then secured to the installation position on the dust collection equipment body with cable ties or ropes. Another method involves forming the filter bags into a cylindrical shape, with a cap at one end. This cap is detachably installed to the dust collection equipment body via a snap-fit ​​mechanism. Both of these filter bag filtration methods can, to a certain extent, achieve the filtration of airborne dust by dust collection equipment.

[0004] However, the existing filter bag structure still has significant drawbacks in practical applications. On the one hand, tying the filter bag with straps or ropes is cumbersome, time-consuming, and inefficient. On the other hand, while assembling the filter bag into a cylindrical shape and using the snap-fit ​​structure of the filter bag end caps for disassembly and installation improves the convenience and efficiency of filter bag installation, the dust removal effect and versatility of existing filter bags still need further improvement. This is because when the ventilation volume of the dust removal equipment is large, the filter bag is prone to deformation, resulting in insufficient direct contact area between the air and the filter bag, leading to a reduction in the filtration area and causing turbulent airflow distribution, thus affecting the filtration effect. Therefore, some manufacturers usually add a support structure inside the cylindrical shape to avoid filter bag deformation. However, since different dust removal equipment has different requirements for the length specifications of the filter bag, the support structure of the filter bag needs to be customized to match the use of different specifications of dust removal equipment. This not only increases the cost but also still affects the direct contact area between the air and the filter bag. Utility Model Content

[0005] To improve the ease of installation and versatility of filter bags, effectively prevent filter bag deformation, and further improve the filtration efficiency and effect, this application provides a quick-installation gusseted filter bag.

[0006] This application provides a quick-installation gusseted filter bag, including a cover plate, a bottom plate, and filter sheets. The filter sheets are continuously folded into a wavy structure, with their edges parallel to the fold lines forming a cylindrical structure. The cover plate and the bottom plate are positioned opposite each other, respectively sealing the openings at both ends of the cylindrical structure. A ventilation hole with a sealed connection to an external dust collector is provided in the middle of the cover plate. A first containment groove is provided on the side of the cover plate near the filter sheets, and a second containment groove is provided on the side of the bottom plate near the filter sheets. Both ends of the filter sheets extend into the first and second containment grooves, respectively, and abut against the bottom of the two grooves. By adopting the above technical solution, the filter sheets are continuously folded into a wavy structure. Compared with existing filter bag structures, this application, through folding into a continuous wavy structure, enables the filter sheets to achieve better stability and resistance to deformation, and has a larger contact area with air, thereby improving filtration efficiency and filtration effect. Meanwhile, the filter elements, parallel to the fold lines, enclose each other to form a cylindrical structure. Both ends extend into the first retaining groove of the cover plate and the second retaining groove of the bottom plate, respectively, and abut against the bottom of the grooves. The wavy structure's resistance to deformation further enhances the restrictive effect of the first and second retaining grooves on the movement of the entire cylindrical structure, making the filter elements less prone to displacement and deformation during use. This simple structural design solves the problem of existing filter elements being easily deformed. Moreover, when adapting to different specifications of dust removal equipment, simply changing the length of the filter elements allows for flexible shortening or increasing of the distance between the cover plate and the bottom plate, thereby improving the applicability of this quick-installation bellows bag to different specifications of dust removal equipment. Preferably, the cover plate, near the filter elements, has a first and a second retaining edge protruding sequentially from the inside out. The first retaining edge, the cover plate, and the second retaining edge together form the first retaining groove. By adopting the above technical solution, the first and second retaining edges protruding sequentially from the inside out on the cover plate near the filter elements allow the first retaining edge, the cover plate, and the second retaining edge to together form the first retaining groove. The first retaining groove allows one end of the filter element to extend into and abut against the bottom of the groove. This structural design provides stable support and positioning for the filter element, preventing it from shaking or shifting during use. This ensures the overall structural stability of the quick-installation gusseted bag, improving its filtration efficiency and service life. Preferably, the bottom plate has a first and a second retaining edge protruding sequentially from the inside to the outside on the side near the filter element. The first retaining edge, the bottom plate, and the second retaining edge together form the second retaining groove. By adopting the above technical solution, the bottom plate has a first and a second retaining edge protruding sequentially from the inside to the outside on the side near the filter element. These two edges, together with the bottom plate, form the second retaining groove, allowing one end of the filter element to extend into and abut against the bottom of the groove. This structural design ensures that when the filter element is installed on the bottom plate, the first and second retaining edges limit and fix the filter element, preventing displacement or shaking during use.Because the filter element is stably fixed within the second enclosure groove, the connection between the filter element and the base plate is ensured, thereby ensuring the overall stability of the filtration device and improving the filtration effect and service life of the equipment. Preferably, the wave-like structure has periodically arranged wave units, wherein the vertical undulation height of each wave unit from its lowest trough to its highest crest remains consistent. By adopting the above technical solution, since the wave-like structure has periodically arranged wave units with consistent vertical undulation height, the structure of each part of the filter element is uniform, ensuring that the contact opportunities and contact areas between air and each part of the filter element are relatively balanced when filtering air, avoiding uneven airflow distribution caused by local structural differences, thereby improving the overall filtration effect of the filter element. Preferably, the side of the cover plate away from the filter element is provided with a first sealing groove for installing a sealing ring, and the first sealing groove surrounds the outer periphery of the ventilation hole. By adopting the above technical solution, a first sealing groove for installing the sealing ring is provided on the side of the cover plate away from the filter element, and the first sealing groove surrounds the outer periphery of the ventilation hole. When the sealing ring is installed in the first sealing groove and connected to the external dust collector, the sealing ring can fill the gap between the cover plate and the external dust collector. Since the first sealing groove surrounds the outer periphery of the ventilation hole, when installed on the external dust collection equipment, it can effectively prevent air leakage from the periphery of the ventilation hole, thereby improving the sealing performance between the quick-installation gusseted bag and the external dust collector. Preferably, the side walls of both the cover plate and the bottom plate are provided with handles extending outwards. By adopting the above technical solution, since the side walls of both the cover plate and the bottom plate are provided with handles extending outwards, when it is necessary to install or disassemble the quick-installation gusseted bag, the operator can directly grasp the handle to apply force, avoiding damage that may be caused by direct contact with the filter element and other components, making it easier for the operator to grip and apply force, thus making it easier and more convenient to complete the installation and disassembly of the quick-installation gusseted bag. Preferably, the handle is T-shaped. By adopting the above technical solution, the handle is designed in a "T" shape, which provides a wider gripping surface compared to other shapes. When operators need to install or remove the quick-installation gusseted bag, the wider gripping surface provides a larger contact area, allowing operators to hold the handle more stably and preventing slippage when force is applied. Preferably, it also includes a chip embedded in the surface of the cover away from the filter sheet.By adopting the above technical solution, the filter sheet is continuously folded into a wavy structure to form a cylindrical shape. The cover plate and the bottom plate seal the openings at both ends of the cylindrical structure. The cover plate has ventilation holes for sealing connection with the external dust collector. The two ends of the filter sheet extend into the first and second enclosure grooves respectively and abut against the bottom of the grooves, thus achieving the filtration of airborne dust. On this basis, a chip is embedded on the surface of the cover plate away from the filter sheet. The chip stores basic information such as model, production date, and filter material. When the installation-type intelligent gusseted bag of this application is installed in the external dust collection equipment, the dust collection equipment can read the information of the chip and monitor the usage of the quick-installation-type intelligent gusseted bag. Preferably, the outer peripheral edges of the cover plate and the bottom plate are both provided with limiting parts that extend horizontally outward to connect with the external dust collection equipment. By adopting the above technical solution, limiting parts for connection with external dust removal equipment are provided on the outer periphery of the cover plate and the bottom plate. When the quick-installation gusseted bag is installed on the external dust removal equipment, the limiting parts contact the external dust removal equipment, which can position the gusseted bag and prevent it from shifting or shaking during installation, ensuring the accuracy of the installation position. This allows the gusseted bag to better cooperate with the external dust removal equipment, improving installation efficiency and stability. Preferably, a second sealing groove for installing a sealing ring is provided on the side of the cover plate away from the filter element, and the second sealing groove surrounds the outer periphery of the first sealing groove. By adopting the above technical solution, a second sealing groove is provided on the side of the cover plate away from the filter element and surrounds the outer periphery of the first sealing groove. During installation, a sealing ring can be installed in these two sealing grooves. Since the second sealing groove surrounds the first sealing groove, a double sealing structure is formed.

[0007] In summary, this application includes at least one of the following beneficial technical effects: 1. The filter is continuously folded into a wave-like structure, which greatly increases its surface area. When it is enclosed to form a cylindrical structure, the direct contact area between the air and the filter increases significantly when the air passes through, thereby increasing the filtration area and ultimately improving the filtration effect. 2. The wavy filter disc has two ends parallel to the fold line that are joined together to form a cylindrical shape. The openings at both ends of the cylindrical shape extend into the first and second enclosure grooves respectively and abut against the bottom of the grooves. Installation can be completed simply by placing the end of the filter disc into the corresponding enclosure groove, avoiding cumbersome binding operations and thus improving installation efficiency. It can maintain its shape even when the ventilation volume is large, without the need to add a custom support structure inside. This reduces costs and can be adapted to dust removal equipment of different specifications, thus having good versatility. Attached Figure Description

[0010] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0011] This application provides a quick-installation spiral-shaped accordion bag, referring to... Figure 1 and Figure 2 The system includes a cover plate 1, a base plate 2, and filter sheets 3 disposed between the cover plate 1 and the base plate 2. The cover plate 1 has a ventilation hole 11 in the middle for sealing connection with an external dust collector. The cover plate 1 and the base plate 2 are positioned opposite each other in a plate-to-plate configuration. The filter sheets 3 are continuously folded into a wavy structure, and the filter sheets 3 are formed into a cylindrical structure along edges parallel to the fold lines. The cylindrical structure of the filter sheets 3 increases the contact area between air and the filter sheets 3, improving filtration efficiency. The opposing surfaces of the cover plate 1 and the base plate 2 seal the openings at both ends of the cylindrical structure. This structural design allows the gusseted bag to be easily installed on dust collection equipment. When the external dust collector is working, air can enter the gusseted bag through the ventilation hole 11, be filtered by the filter sheets 3, and then be discharged, effectively achieving air filtration. Alternatively, air can enter the gusseted bag from the outside for filtration and then flow out through the ventilation hole 11. It is worth noting that the wavy structure itself has a certain degree of stability, reducing deformation under high ventilation volumes.

[0012] Specifically, the filter element 3 in this embodiment is made of a fiber material with good filtration performance, such as polyester fiber or polypropylene fiber. Polyester fiber has the characteristics of high strength, good elasticity, and corrosion resistance, while polypropylene fiber has the advantages of light weight, good chemical stability, and suitable filtration precision. These materials can effectively intercept dust particles in the air and ensure the filtration effect.

[0013] Specifically, the filter element 3 is folded into a wave-like structure, with each fold line parallel to the others, and the vertical undulation height of each wave unit from its lowest trough to its highest crest remains consistent. This design ensures that air is evenly distributed across all parts of the filter element 3 as it passes through, preventing localized over- or under-filtration and guaranteeing stable filtration performance. Furthermore, this periodically arranged wave unit arrangement makes quality control and assurance during manufacturing; wave units with the same undulation height can be precisely manufactured using molds and other tools. The wave-like structure of the filter element 3 forms a cylindrical structure with a larger surface area. The wave-like design increases the pleats of the filter element 3, thereby increasing its outer surface area and providing a larger filtration area, thus improving filtration efficiency.

[0014] Reference Figure 1 and Figure 3 Specifically, in this embodiment, the cover plate 1 near the filter element 3 has a first perimeter 12 and a second perimeter 13 protruding from the inside to the outside. The first perimeter 12, the cover plate 1 and the second perimeter 13 enclose each other to form a first retaining groove 14. The bottom plate 2 near the filter element 3 has a first retaining edge 21 and a second retaining edge 22 protruding from the inside to the outside. The first retaining edge 21, the bottom plate 2 and the second retaining edge 22 enclose each other to form a second retaining groove 23. The two ends of the cylindrical filter element 3 extend into the first retaining groove 14 of the cover plate 1 and the second retaining groove 23 of the bottom plate 2, respectively. The two end faces of the cylindrical structure abut against the bottom of the first retaining groove 14 and the second retaining groove 23, respectively. The side walls of the two ends of the cylindrical structure abut against the inner walls of each perimeter and retaining edge to restrict the movement of the cylindrical filter element 3.

[0015] The first perimeter 12 and the second perimeter 13 are integrally formed with the cover plate 1, and the first baffle 21 and the second baffle 22 are integrally formed with the base plate 2. This integral forming method ensures the stability and sealing of the structure, preventing air leakage due to gaps during use. The height and width of each perimeter and baffle can be designed according to the thickness of the filter element 3 and actual needs. If the filter element 3 is thicker, the height of the perimeter and baffle can be appropriately increased, and the width can be adjusted accordingly to ensure that the filter element 3 can be tightly inserted into the first baffle groove 14 and the second baffle groove 23 and fully contact the groove wall, ensuring the stability of the filter element 3 installation.

[0016] Specifically, in this embodiment, the cover plate 1, on the side away from the filter element 3, is provided with a first sealing groove 15 and a second sealing groove 16 from the inside out for installing a sealing ring. The first sealing groove 15 surrounds the outer periphery of the ventilation hole 11, and the second sealing groove 16 surrounds the outer periphery of the first sealing groove 15. During installation, the rubber sealing ring is placed in the first sealing groove 15 and the second sealing groove 16. When the cover plate 1 is connected to the external dust collector, the double sealing ring can play a sealing role, preventing air from leaking from the connection between the ventilation hole 11 and the external dust collector.

[0017] Furthermore, in this embodiment, both the cover plate 1 and the bottom plate 2 have horizontally extending limiting parts 4 that connect to external dust removal equipment. The limiting part 4 is a horizontally extending annular protrusion structure perpendicular to the fold line of the filter sheet 3. When the gusseted bag is installed on the dust removal equipment, the limiting part 4 can cooperate with the installation part of the dust removal equipment to play a role in positioning and fixing, ensuring that the gusseted bag is installed accurately and stably, and preventing the gusseted bag from shifting or shaking during use.

[0018] It is worth mentioning that, in this embodiment, both the base plate 2 and the cover plate 1 have outwardly extending handles 5 on their sidewalls. The handles 5 facilitate operation when installing and removing the gusseted bag. The handles 5 are T-shaped, which makes the grip more comfortable and stable, and easier to apply force. The horizontal bar of the T-shaped handle 5 provides a larger gripping area, while the vertical bar facilitates the application of force. The handles 5 can also be designed in other shapes, such as circular or elliptical.

[0019] Specifically, in this embodiment, a chip 6 is embedded in the surface of the cover plate 1 away from the filter element 3. The chip 6 can store relevant information about the gusseted bag, such as usage time, filtration efficiency, and replacement cycle. By recording the usage time, the operator can promptly understand the duration of the gusseted bag's use and determine whether replacement is necessary; recording the filtration efficiency helps the operator understand whether the filtration performance of the gusseted bag has declined; setting the replacement cycle reminds the operator to replace the gusseted bag on time, ensuring the normal operation of the dust removal equipment. The chip 6 can transmit data with external devices via wireless communication technology, enabling intelligent management.

[0020] The implementation principle of this embodiment is as follows: The quick-installation gusseted bag increases the filtration area through the wavy structure of the filter element 3, allowing for more thorough contact between the air and the filter element 3, thereby improving filtration efficiency. Simultaneously, the stability of the wavy structure reduces deformation issues under high ventilation volumes, ensuring stable filtration performance. The design of the retaining grooves in the cover plate 1 and bottom plate 2, along with the setting of the limiting part 4, allows the gusseted bag to be stably installed on the dust removal equipment. The retaining grooves provide fixation and support for the filter element 3, while the limiting part 4 ensures the accuracy and stability of the installation position and facilitates disassembly and replacement. The design of the first sealing groove 15 and the second sealing groove 16 ensures a sealed connection with the external dust collector, preventing air leakage and ensuring the normal operation of the dust removal equipment. The handle part 5 facilitates operation, improves the ease of installation and disassembly, and reduces the labor intensity of operators. The embedded chip 6 enables intelligent management of the gusseted bag. Therefore, compared with existing filter bags, this gusseted bag structure significantly improves filtration efficiency, installation convenience, versatility, and management and maintenance, reducing production costs and improving production efficiency and safety.

[0021] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
