[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0031] Traditional plate filter elements are prone to clogging, which seriously affects the filtration efficiency. At the same time, when impacted, they are prone to bending, which not only further reduces the filtration efficiency, but also increases the maintenance cost. In the face of these problems, the filter element needs to be replaced regularly or manually cleaned, which not only consumes manpower and material resources, but may also affect the continuity of production, bringing many inconveniences to the company's production.

[0032] Based on these drawbacks of the traditional plate filter elements, the embodiments of the present disclosure aim to provide a new filter assembly to effectively solve the problem that the traditional plate filter elements are easy to bend, which affects the filtering efficiency and production continuity.

[0033] Example 1

[0034] The present disclosure provides a filter assembly, such as Figure 1As shown, it includes: a filter element 1, the filter element 1 includes a plurality of interconnected plates, the plurality of plates enclose a cavity 101, a filter membrane layer is provided on a surface of the plate facing the cavity 101, and a first opening is provided on one side of the cavity 101, and dust-containing gas can pass through the plate via the filter membrane layer into the cavity 101 and be discharged from the first opening; a reinforcing plate 2, the reinforcing plate 2 is arranged in the cavity 101, and is fixedly connected to the plate arranged toward the first opening, and the reinforcing plate 2 is arranged perpendicular to the first opening.

[0035] The filter element 1 is composed of a plurality of interconnected plates, which are enclosed together to form a cavity 101. A filter membrane layer is provided on the surface of the plate facing the cavity 101. The filter membrane layer can use high-performance filter media such as nanofiber membranes and ceramic membranes, combined with special surface treatment processes to improve the filtering accuracy and corrosion resistance. In actual application scenarios, for example, when treating dusty gases, the dusty gas can pass through the plate and then enter the cavity 101 through the filtering effect of the filter membrane layer. A first opening is provided on one side of the cavity 101, and the filtered gas will eventually be discharged from this first opening, thereby achieving filtering treatment of the dusty gas.

[0036] The reinforcing plate 2 is arranged in the cavity 101 of the filter element 1, and is fixedly connected to the plate body arranged toward the first opening, and the reinforcing plate 2 is perpendicular to the first opening. The reinforcing plate 2 can support the filter element 1, and by making the reinforcing plate 2 perpendicular to the first opening, it is possible to prevent the reinforcing plate 2 from obstructing the filtered gas from entering the first opening.

[0037] During the filtering process, the traditional plate filter element 1 will be impacted by the airflow and easily bend. This will cause the filter holes on one side of the filter surface to shrink due to squeezing, while the filter holes on the other side of the filter surface will be stretched and enlarged. This will not only reduce the filtering efficiency, but also affect the filtering quality. If the pressure resistance of the filter element 1 is to be improved, the wall thickness of the filter plate is usually increased, but this will still lead to a decrease in filtering efficiency.

[0038] The filter assembly provided in the embodiment of the present disclosure enhances the structural stability of the filter element 1 by providing the reinforcing plate 2. When the filter element 1 is impacted, it can better resist external forces and reduce the occurrence of bending, so that the filter element 1 can reduce the wall thickness and ensure continuous and stable operation.

[0039] In some embodiments, the filter element 1 is a rectangular cube structure, and the first opening is located on a side of the rectangular cube structure having thickness; a pair of plates in the filter element 1 are arranged opposite to each other along the thickness direction, which are the first plates 102, and the reinforcing plate 2 is located in the middle of the pair of first plates 102 and is arranged parallel to the pair of first plates 102.

[0040] The filter element 1 is in the shape of a rectangular cube as a whole, having six faces, including four side faces, a top face and a bottom face. The first opening is located on a side face of the rectangular cube having "thickness". In this rectangular cube structure, there is a pair of plates arranged opposite to each other along the thickness direction, which are located on both sides of the rectangular cube, facing each other, and are named as first plates 102. The reinforcing plate 2 is located in the middle of the pair of oppositely arranged first plates 102 and is parallel to them. The side edges of the reinforcing plate 2 are fixedly connected to the plates on the side faces of the filter element 1 by welding or the like. In this way, the reinforcing plate 2 greatly enhances the overall structural strength of the filter element 1.

[0041] In the actual working process, when the dust-laden gas passes through the plate body and the filter membrane layer, a certain pressure will be generated on the plate body. The reinforcing plate 2 can evenly provide support force for the pair of opposite first plate bodies 102, effectively disperse and withstand these pressures, and prevent the opposite first plate bodies 102 from bending or deforming due to uneven force. Since the first plate body 102 has a large area, the reinforcing plate 2 is set parallel to the first plate body 102, which can ensure the normal filtering function of the first plate body 102 while preventing the first plate body 102 from bending. This allows the thickness of the first plate body 102 to be appropriately reduced, thereby improving the filtering efficiency while ensuring the filtering quality.

[0042] The filter element 1 is designed as a rectangular cube structure. This common and regular shape is easy to install and layout in various fluid processing systems. Moreover, the rectangular cube structure is matched with a specific plate body and reinforcement plate 2 layout, which can optimize the flow path of the fluid in the filter element 1, reduce turbulence, and reduce energy loss while improving filtration efficiency.

[0043] In some embodiments, the plate body connected to the reinforcing plate 2 is a second plate body 103 , and the thickness of the second plate body 103 is greater than the thickness of the first plate body 102 .

[0044] In the filter assembly, the plate body directly connected to the reinforcing plate 2 is the second plate body 103, and its thickness will be increased. In view of the relatively small area of ​​the second plate body 103, even if its thickness is increased, it will not have a significant impact on the filtration efficiency. The second plate body 103 connected to the reinforcing plate 2 is subjected to more complex and powerful pressure and impact during operation. On the one hand, it has to withstand the pressure exerted by the dust-laden gas when it passes through, and on the other hand, it has to rely on the reinforcing plate 2 to transmit and disperse the forces from other different directions. By increasing the thickness of the second plate body 103, its strength and compressive resistance can be significantly enhanced. In this way, during long-term use, the second plate body 103 can effectively avoid problems such as rupture or deformation due to excessive force, thereby ensuring that the entire filter assembly can always operate normally.

[0045] In some embodiments, Figure 2 As shown, the filter assembly also includes: a fluid pipeline 3, which is arranged in a vertical direction, the bottom end of the fluid pipeline 3 is closed, and the top end is used to connect to the air collecting chamber 20, and the fluid pipeline 3 is provided with a plurality of second openings 301 on the side wall along its length direction; there are multiple filter elements 1, the first opening of the filter element 1 is connected to the second opening 301, and the cavity 101 is connected to the fluid pipeline 3.

[0046] The filter assembly includes a fluid pipe 3 arranged in a vertical direction, the bottom end of the pipe is in a closed state, and the top end is interconnected with the gas collecting chamber 20, so that the fluid can flow from bottom to top and finally enter the gas collecting chamber 20. A plurality of second openings 301 are arranged on the side wall of the fluid pipe 3 along its length direction. These second openings 301 are evenly or unevenly distributed on the side wall of the pipe, providing an interface for the connection between the filter element 1 and the fluid pipe 3. The filter assembly includes a plurality of filter elements 1, and the first opening of each filter element 1 corresponds to and docks with the second opening 301 on the side wall of the fluid pipe 3 one by one, and the cavity 101 inside the filter element 1 is connected to the fluid pipe 3 through the docking opening. When a fluid such as dust-containing gas enters the filter element 1, after being filtered by the filter membrane layer, the clean gas enters the cavity 101, and then enters the fluid pipe 3 through the opening connected with the fluid pipe 3, and finally flows to the gas collecting chamber 20.

[0047] The connection method of multiple filter elements 1 and fluid pipe 3 greatly increases the filtering area, can filter a large amount of dust-containing gas at the same time, and improves the filtering efficiency. The filtered gas is collected in the gas collecting chamber 20 in an orderly manner through the fluid pipe 3, which is convenient for subsequent unified processing and utilization, and realizes efficient gas collection. The vertically arranged fluid pipe 3 and the connection method of multiple filter elements 1 along the side wall of the pipe can reasonably arrange the filtering system in a limited space, saving space.

[0048] In some embodiments, the filter assembly further includes: a connector 4 connected to the side wall of the fluid conduit 3 near the second opening 301 ; and one end of the filter element 1 having the first opening is detachably connected to the connector 4 .

[0049] In the filter assembly, there is a connector 4. The connector 4 is close to the second opening 301 on the side wall of the fluid pipeline 3 and is connected to the side wall of the fluid pipeline 3. For example, the connector 4 can be firmly fixed to the side wall of the fluid pipeline 3 by welding, bolt connection or clamp connection, ensuring that the connection between it and the pipeline is tight and stable, and will not loosen or leak during the flow of fluid.

[0050] The end of the filter element 1 with the first opening is detachably connected to the connector 4. This means that the filter element 1 can be easily assembled and disassembled with the connector 4. Common detachable connection methods include, but are not limited to, threaded connection, snap connection, or plug-in connection. Taking the snap connection as an example, a snap structure matching the connector 4 is provided at the end of the filter element 1 with the first opening. When installing, it is only necessary to align the snap of the filter element 1 with the slot on the connector 4 and gently press to complete the connection; when disassembling, the filter element 1 can be removed from the connector 4 by opening the snap through a simple operation.

[0051] The filter element 1 and the connector 4 are detachably connected, which greatly improves the convenience of maintenance. When the filter element 1 is blocked, damaged, or reaches the end of its service life, there is no need to disassemble the entire filter element 1 on a large scale. The filter element 1 can be easily removed from the connector 4 for replacement or repair. This not only saves maintenance time and labor costs, but also reduces system downtime caused by maintenance and improves production efficiency.

[0052] In some embodiments, Figure 3 As shown, the connector 4 includes a pair of blocks 401, which are bolted to the side wall of the fluid conduit 3, and the pair of blocks 401 are relatively arranged on both sides of the second opening 301 to form a slot; the filter element 1 has a thickness at one end of the first opening that matches the width of the slot.

[0053] The connector 4 is composed of a pair of blocks 401, which are connected to the side wall of the fluid pipeline 3 by bolts. During the installation process, holes are first punched at the corresponding positions of the side wall of the fluid pipeline 3, and then the bolt holes on the blocks 401 are aligned with the holes on the side wall of the pipeline, and the bolts are tightened so that the blocks 401 are firmly fixed on the side wall of the pipeline. This pair of blocks 401 are relatively arranged on both sides of the second opening 301 on the side wall of the fluid pipeline 3. When they are installed in place, a slot is formed between the two blocks 401. The thickness of the first opening end of the filter element 1 is adapted to the width of the slot. In other words, the end of the filter element 1 with the first opening can be just embedded in the slot. In actual operation, the end of the filter element 1 is aligned with the slot, and then pushed in, so that the positioning of the filter element 1 and the connector 4 can be achieved.

[0054] This connection mode of matching the filter element 1 with the card slot makes the installation and removal of the filter element 1 very convenient. When installing, the filter element 1 only needs to be inserted into the card slot; when removing, it only needs to be pulled out of the card slot, without complicated tools and operation steps. This greatly improves the efficiency of maintaining and replacing the filter element 1 and reduces system downtime.

[0055] In some embodiments, the fluid conduit 3 is a cubic structure, and a plurality of second openings 301 are arranged in an array on each side of the fluid conduit 3 ; and an air duct is provided between two adjacent filter elements 1 on the fluid conduit 3 .

[0056] The fluid pipeline 3 adopts a cubic structure, and this shape makes the pipeline more regular in spatial layout, which is convenient for installation and coordination with other filter components. A plurality of second openings 301 are arranged in an array on each side of the fluid pipeline 3. For example, in a rectangular parallelepiped-shaped fluid pipeline 3, the four sides are neatly arranged with second openings 301, and these openings are distributed according to a certain spacing and row and column pattern to form an orderly array. Such a design can make full use of the side space of the pipeline, increase the connection points with the filter element 1, and thus increase the filtration area. More filter elements 1 can filter the fluid at the same time, thereby improving the filtration efficiency and processing capacity of the entire filtration system, and can meet the needs of large-scale fluid processing. Moreover, the compact arrangement of multiple filter elements 1 can reduce the flow dead zone of the fluid, thereby reducing the possibility of dust bridging.

[0057] Multiple filter elements 1 are respectively connected to the second openings 301 on the side of the fluid pipeline 3. Since the second openings 301 are arranged in an array, the filter elements 1 are also neatly arranged on the side of the pipeline. There are air ducts between two adjacent filter elements 1 on the fluid pipeline 3. These air ducts provide flow channels for the gas, increase the contact area between the fluid and the surface of the filter element 1, and provide channels for subsequent cleaning pulses, so that dust accumulated on the surface of the filter element 1 can be washed away.

[0058] In some embodiments, the length direction of the second opening 301 is arranged along the vertical direction, and the size of the first opening is matched with the second opening 301 .

[0059] The fluid conduit 3 is a cube structure and is arranged in the vertical direction. On each side thereof, a plurality of second openings 301 are distributed in the form of an array. The length direction of these second openings 301 is also vertical, that is, the long side of each opening is vertical and the short side is horizontal.

[0060] Each filter element 1 is surrounded by a plurality of interconnected plates, a cavity 101 is formed inside, and a first opening is provided on one side of the cavity 101. The first opening is adapted to the second opening 301 in size, specifically, the shapes and sizes of the two can be closely docked. For example, if the second opening 301 is a rectangle, then the first opening is also a rectangle of corresponding size, so that when docking, the two can perfectly match in length, width and shape to achieve seamless connection. Based on this adaptation relationship, the filter element 1 connected thereto is also arranged in the vertical direction, and the overall structure is a rectangular parallelepiped. Among them, the first plate 102 with the largest surface area is also placed vertically.

[0061] By arranging the second opening 301 in the vertical direction, when the dust deposited on the surface of the first plate 102 reaches a certain thickness, the gravity on the powder cake itself will be greater than the drag force of the dust-laden airflow on the powder cake and the adhesion force between the powder cake and the first plate 102. At this time, under the action of the loose wind in the dust-laden airflow, the powder cake on the surface of the first plate 102 will fall off as a whole in the form of flakes. This feature can reduce the number of additional cleaning times for the filter assembly, thereby improving the filtering efficiency.

[0062] In some embodiments, the filter assembly further includes: a buffer portion 5 , which is disposed on a side surface of the filter element 1 having the first opening; and a pair of blocks 401 disposed at the bottom of the second opening 301 .

[0063] In the filter assembly, the buffer portion 5 is disposed on the side surface of the filter element 1 with the first opening. The buffer portion 5 can be made of a flexible material, such as rubber, silicone, and other materials with good elasticity and chemical resistance. When the filter element 1 is docked with the second opening 301 on the fluid pipeline 3, the buffer portion 5 will be squeezed, thereby forming a seal between the filter element 1 and the fluid pipeline 3, effectively preventing the dust-containing fluid from entering the fluid pipeline 3.

[0064] There is a pair of blocks 401 on the connector 4, which are arranged at the bottom of the second opening 301. The pair of blocks 401 are connected to the side wall of the fluid conduit 3 by bolts, and are relatively distributed at the bottom of the second opening 301, forming a slot together. When installing the filter element 1, it is only necessary to align the end of the filter element 1 with the first opening with the slot, and then insert it from top to bottom to complete the installation operation. After the installation is completed, the blocks 401 will support and fix the filter element 1 from the bottom.

[0065] In this installation method, the filter element 1 will squeeze the buffer part 5 under the action of the block 401, and the friction force generated between the buffer part 5 and the fluid pipeline 3 can provide a stable supporting force for the filter element 1, ensuring that the filter element 1 will not slide down due to gravity or the impact force of the fluid.

[0066] Since the block 401 is located at the bottom of the second opening 301, the buffer part 5 at the top of the filter element 1 is not limited by the block 401, and its compression amount is smaller than that of the buffer part 5 at the bottom. However, the buffer part 5 at the top will still be in close contact with the surface of the fluid pipeline 3. Under the action of loose wind in the dust-laden airflow, due to the small compression amount of the top buffer part 5, the filter element 1 will slightly shake left and right on the fluid pipeline 3. This shaking can make the powder cake deposited on the surface of the first plate body 102 easier to fall off, and the buffer part 5 can also ensure the sealing effect between the filter element 1 and the fluid pipeline 3. And since the reinforcing plate 2 is provided in the filter element 1, since the reinforcing plate 2 enhances the structural stability of the filter element 1, even if the filter element 1 shakes slightly left and right under the impact of the airflow, the occurrence of bending can be reduced, so that the filter element 1 can reduce the wall thickness and ensure continuous and stable operation.

[0067] Example 2

[0068] The present invention provides a filtering device, such as Figure 4 and Figure 5 As shown, it includes the filter component 10 provided in Example 1.

[0069] A plurality of filter assemblies 10 are arranged inside the filter device, and these filter assemblies 10 are arranged in the filter device in a vertical direction. The filter device is cylindrical in shape as a whole, and a gas collecting chamber 20 is arranged on the top thereof, and an air outlet 30 is opened on the top of the gas collecting chamber 20, and the air outlet 30 is used to recover the treated gas. An air inlet 40 is arranged on the side of the filter device, and the dust-containing gas enters the device through it. And at the bottom of the filter device, a dust outlet 50 is arranged, and the dust falling off the filter element will be discharged through this dust outlet 50.

[0070] The filter device is also equipped with an intelligent control unit, which is connected to the filter assembly 10. The main function of the intelligent control unit is to detect the filter resistance of the filter assembly 10 in real time. When the filter resistance is detected to increase and reach a preset threshold, the intelligent control unit will automatically start the backwashing system. The backwashing system will use high-pressure fluid or airflow to reversely flush the surface of the filter element, thereby removing impurities accumulated on the surface of the filter element and restoring the filter performance of the filter element.
