Description

Technical Field

[0001] This application relates to the field of ceramic filtration equipment technology, and in particular to a composite ceramic filter. Background Technology

[0002] Both foam ceramics and honeycomb ceramics have filtration functions, but because foam ceramics have larger pores, their filtration accuracy is lower, while honeycomb ceramics have smaller pores, their filtration accuracy is higher. Therefore, combining foam ceramics and honeycomb ceramics into a composite ceramic filter can not only ensure high filtration accuracy, but also effectively improve filtration efficiency.

[0003] One method for fixing foam ceramics and honeycomb ceramics is by adhesive bonding. When it is necessary to fix foam ceramics and honeycomb ceramics together, a composite adhesive is applied to one end of the honeycomb ceramic, and then the foam ceramic is placed on the honeycomb ceramic. Once the composite adhesive has bonded and fixed the honeycomb ceramic and the foam ceramic together, the fixed connection between the foam ceramic and the honeycomb ceramic is complete.

[0004] When connecting foam ceramics and honeycomb ceramics using the above method, the long curing time of the composite adhesive results in a longer waiting time for fixing the foam ceramics and honeycomb ceramics, thus reducing the installation efficiency of the honeycomb ceramics and foam ceramics. Utility Model Content

[0005] To improve the efficiency of fixing foam ceramics and honeycomb ceramics, this application provides a composite ceramic filter.

[0006] This application provides a composite ceramic filter, which adopts the following technical solution: A composite ceramic filter, comprising: Foam ceramics, which can filter large particulate impurities; The honeycomb ceramic is located directly below the foam ceramic and can filter out small particulate impurities. The mounting component is fixedly disposed on the outer periphery of the foam ceramic, and the mounting component can fix the foam ceramic and the honeycomb ceramic in a fixed connection.

[0007] By adopting the above technical solution, when it is necessary to fix the foam ceramic and the honeycomb ceramic together, the honeycomb ceramic is placed on a horizontal table, and the foam ceramic is placed directly above the honeycomb ceramic, aligning the mounting component with the honeycomb ceramic. After the mounting component is aligned with the honeycomb ceramic, the foam ceramic is pressed towards the honeycomb ceramic. Under pressure, the foam ceramic moves towards the honeycomb ceramic, which in turn moves the mounting component until it is embedded in the honeycomb ceramic, thus completing the fixation of the foam ceramic and the honeycomb ceramic. This method of fixing the foam ceramic and the honeycomb ceramic together avoids the need to wait for the composite adhesive to cure, thereby effectively improving the efficiency of connecting the foam ceramic and the honeycomb ceramic.

[0008] Optionally, the honeycomb ceramic has a horizontally provided connecting groove at one end near the foam ceramic, and the mounting component includes: The mounting plate is fixedly disposed on the outer periphery of the foam ceramic, and the mounting plate is located at the end of the foam ceramic near the honeycomb ceramic. Two rotating plates are symmetrically arranged along the mounting plate, and each rotating plate is rotatably mounted on the mounting plate. A spring, one end of which is fixedly connected to the end of the rotating plate near the mounting plate, and the other end of which is fixedly connected to the end of the mounting plate near the rotating plate.

[0009] By adopting the above technical solution, when connecting foam ceramics and honeycomb ceramics, the honeycomb ceramics are placed on a horizontal table, and the foam ceramics are placed directly above the honeycomb ceramics, with the mounting plate aligned with the connecting groove. After alignment, the foam ceramics are pressed towards the honeycomb ceramics. Under pressure, the foam ceramics move the mounting plate and rotating plate towards the honeycomb ceramics. During this movement, the rotating plate experiences pressure from the inner wall of the connecting groove. This pressure causes the rotating plate to rotate towards the mounting plate and compress the spring until it is fully embedded in the connecting groove. The pressure on the rotating plate then disappears, the spring returns to its initial state, and the rotating plate rotates away from the mounting plate until it returns to its initial position. Once back in its initial position, the rotating plate contacts the inner wall of the connecting groove, thus achieving a fixed connection between the foam ceramics and the honeycomb ceramics. This method avoids the need to wait for the composite adhesive to cure during the connection process, effectively improving the efficiency of connecting foam ceramics and honeycomb ceramics.

[0010] Optionally, the foam ceramic and the honeycomb ceramic are fixedly connected by a mating component, the mating component comprising: A fixing plate is fixedly mounted on the workbench, and a horizontal mounting groove is provided on the fixing plate, the gap of which is consistent with the width of the honeycomb ceramic. A mating plate is fixedly disposed at one end of a fixed plate. A mating groove is vertically disposed on the mating plate, which communicates with the mounting groove and has the same width as the foam ceramic.

[0011] By adopting the above technical solution, when connecting foam ceramics and honeycomb ceramics, the honeycomb ceramic is placed in the mounting groove, with one end embedded in the mating groove. After the honeycomb ceramic is embedded in the mating groove, the foam ceramic moves along the mating groove towards the honeycomb ceramic. This movement of the foam ceramic causes the mounting plate and rotating plate to move towards the honeycomb ceramic. During this movement, the rotating plate experiences pressure from the inner wall of the connecting groove. Under this pressure, the rotating plate rotates towards the mounting plate and compresses the spring until it is fully embedded in the connecting groove. At this point, the pressure on the rotating plate disappears, and the spring releases its elastic potential energy, causing it to return to its initial position. Once back in its initial position, the rotating plate contacts the inner wall of the connecting groove, thus achieving a fixed connection between the foam ceramic and the honeycomb ceramic. This method of connecting foam ceramics and honeycomb ceramics avoids the need to repeatedly adjust the positions of the honeycomb ceramics and foam ceramics to ensure that the rotating plate and the connecting groove are on the same horizontal line in the vertical direction, effectively improving the convenience of connecting foam ceramics and honeycomb ceramics.

[0012] Optionally, multiple springs are provided at intervals along the rotating plate.

[0013] By adopting the above technical solution, the arrangement of multiple springs can ensure that when the rotating plate moves towards the connecting groove and rotates due to pressure from the inner wall of the connecting groove, the multiple springs can disperse the pressure on the rotating plate and prevent the rotating plate from deviating when rotating towards the mounting plate, thereby effectively improving the stability of the rotating plate when entering the connecting groove.

[0014] Optionally, the pore size of the foam ceramic is larger than that of the honeycomb ceramic.

[0015] By adopting the above technical solution, the pore size of the foam ceramic is larger than that of the honeycomb ceramic. This allows the foam ceramic to preliminarily filter large particles of impurities during the filtration process, preventing large particles from clogging the pores of the honeycomb ceramic. This effectively improves the stability of the filtration process when using the foam ceramic and honeycomb ceramic after they have been connected.

[0016] Optionally, the surfaces of the foam ceramic and the honeycomb ceramic are coated with an anti-stick coating.

[0017] By adopting the above technical solution, the anti-stick coating can ensure that impurities will not adhere to the surface of the foam ceramic and honeycomb ceramic during the filtration process after the connection is completed. This avoids the situation where impurities clog the pores during the filtration process of the foam ceramic and honeycomb ceramic, and further improves the stability of the foam ceramic and honeycomb ceramic during the filtration process.

[0018] Optionally, a guide slope is fixedly provided at the end of the rotating plate away from the mounting plate.

[0019] By adopting the above technical solution, the setting of the guide slope can ensure that the rotating plate will not get stuck with the inner wall of the connecting groove during the process of moving towards the bottom of the connecting groove. This avoids the situation where the rotating plate cannot fully enter the connecting groove, which would prevent the foam ceramic and the honeycomb ceramic from being connected. This further improves the stability of the rotating plate when moving towards the bottom of the connecting groove.

[0020] Optionally, the foam ceramic and the honeycomb ceramic have a rectangular structure.

[0021] By adopting the above technical solution, the rectangular structure of the honeycomb ceramic and the foam ceramic ensures that the foam ceramic and the honeycomb ceramic will not rotate relative to each other after the connection is completed, thereby further improving the stability of the foam ceramic and the honeycomb ceramic after the connection is completed.

[0022] In summary, this utility model embodiment provides a composite ceramic filter, which includes at least one of the following beneficial technical effects: 1. When it is necessary to fix the foam ceramic and the honeycomb ceramic together, place the honeycomb ceramic on a horizontal table, and place the foam ceramic directly above the honeycomb ceramic, aligning the mounting piece with the honeycomb ceramic. After the mounting piece is aligned with the honeycomb ceramic, press the foam ceramic towards the honeycomb ceramic. Under pressure, the foam ceramic moves towards the honeycomb ceramic, which in turn moves the mounting piece until it is embedded in the honeycomb ceramic, thus completing the fixation of the foam ceramic and the honeycomb ceramic. This method of fixing the foam ceramic and the honeycomb ceramic together avoids the need to wait for the composite adhesive to cure, thereby effectively improving the efficiency of the connection process.

[0023] 2. When connecting foam ceramics and honeycomb ceramics, place the honeycomb ceramics on a horizontal table, and place the foam ceramics directly above them, aligning the mounting plate with the connecting groove. After alignment, press the foam ceramics towards the honeycomb ceramics. The pressure on the foam ceramics causes the mounting plate and rotating plate to move closer to the honeycomb ceramics. During this movement, the rotating plate experiences pressure from the inner wall of the connecting groove. This pressure causes the rotating plate to rotate towards the mounting plate and compress the spring until it is fully embedded in the connecting groove. The pressure then dissipates, the spring returns to its initial state, and the rotating plate rotates away from the mounting plate until it returns to its initial position. Once back in its initial position, the rotating plate contacts the inner wall of the connecting groove, thus achieving a secure connection between the foam ceramics and the honeycomb ceramics. This method of connecting foam ceramics and honeycomb ceramics avoids the need to wait for the composite adhesive to cure, effectively improving the efficiency of the connection process.

[0024] 3. When connecting foam ceramics and honeycomb ceramics, place the honeycomb ceramic in the mounting groove, ensuring one end of the honeycomb ceramic is embedded in the mating groove. After the honeycomb ceramic is embedded, the foam ceramic moves along the mating groove towards the honeycomb ceramic. This movement of the foam ceramic causes the mounting plate and rotating plate to move towards the honeycomb ceramic. During this movement, the rotating plate experiences pressure from the inner wall of the connecting groove. This pressure causes the rotating plate to rotate towards the mounting plate and compress the spring until it is fully embedded in the connecting groove. At this point, the pressure on the rotating plate disappears, and the spring releases its elastic potential energy, causing it to return to its initial position. Once back in its initial position, the rotating plate contacts the inner wall of the connecting groove, thus achieving a fixed connection between the foam ceramic and the honeycomb ceramic. This method of connecting foam ceramics and honeycomb ceramics avoids the need for repeated adjustments to the positions of the honeycomb ceramics and foam ceramics to ensure the rotating plate and connecting groove are vertically aligned, effectively improving the convenience of connecting foam ceramics and honeycomb ceramics.

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] Combination Figure 1 This application discloses a composite ceramic filter, including a foam ceramic 1, a honeycomb ceramic 11, and an installation component 2. The foam ceramic 1 can filter large particulate impurities. The honeycomb ceramic 11 is located directly below the foam ceramic 1 and can filter small particulate impurities. The installation component 2 is fixedly disposed on the outer periphery of the foam ceramic 1 and can fix the foam ceramic 1 and the honeycomb ceramic 11 together.

[0029] In this embodiment, the foam ceramic 1 and the honeycomb ceramic 11 have the same specifications. The honeycomb ceramic 11 is located directly below the foam ceramic 1. The mounting part 2 has the same specifications as the foam ceramic 1. The mounting part 2 is fixedly connected to the foam ceramic 1 by integral molding.

[0030] In practical use, when it is necessary to fix the foam ceramic 1 and the honeycomb ceramic 11, place the honeycomb ceramic 11 on a horizontal table, place the foam ceramic 1 directly above the honeycomb ceramic 11, and apply vertical pressure to the foam ceramic 1 after placing it directly above the honeycomb ceramic 11. After being subjected to pressure, the foam ceramic 1 will drive the mounting part 2 to move closer to the honeycomb ceramic 11 until the mounting part 2 is embedded in the honeycomb ceramic 11, thus completing the fixed connection between the foam ceramic 1 and the honeycomb ceramic 11.

[0031] Combination Figure 2 Figure 3 and Figure 4In a specific embodiment, a connecting groove 21 is horizontally provided at one end of the honeycomb ceramic 11 near the foam ceramic 1. The mounting component 2 includes a mounting plate 22, a rotating plate 23, and a spring 24. The mounting plate 22 is fixedly disposed on the outer periphery of the foam ceramic 1 and is located at one end of the foam ceramic 1 near the honeycomb ceramic 11. Two rotating plates 23 are symmetrically arranged along the mounting plate 22, and each rotating plate 23 is rotatably disposed on the mounting plate 22. One end of the spring 24 is fixedly connected to the end of the rotating plate 23 near the mounting plate 22, and the other end of the spring 24 is fixedly connected to the end of the mounting plate 22 near the rotating plate 23. Foam ceramic 1 and honeycomb ceramic 11 are fixedly connected by a mating component 3, which includes a fixing plate 31 and a mating plate 33. The fixing plate 31 is fixedly mounted on the worktable, and a horizontal mounting groove 32 is provided on the fixing plate 31. The gap of the mounting groove 32 is the same as the width of the honeycomb ceramic 11. The mating plate 33 is fixedly mounted on one end of the fixing plate 31, and a vertical mating groove 34 is provided on the mating plate 33. The mating groove 34 communicates with the mounting groove 32, and the width of the mating groove 34 is the same as that of the foam ceramic 1. Multiple springs 24 are spaced apart along the rotating plate 23. A guide slope 4 is fixedly provided at the end of the rotating plate 23 away from the mounting plate 22.

[0032] In this embodiment, the connecting groove 21 is a U-shaped groove, and the mounting plate 22 is a T-shaped structure. The mounting plate 22 can be fixedly connected to the foam ceramic 1 by integral molding or by adhesive bonding; no specific limitation is made in this embodiment. The spring 24 is fixedly connected to the mounting plate 22 and the rotating plate 23 by integral molding. The rotating plate 23 is a rectangular structure and is rotatably connected to the mounting plate 22 by a hinge. The fixing plate 31 is a rectangular plate, the mounting groove 32 is a rectangular groove, and the mating plate 33 is a rectangular plate. The mating plate 33 can be fixedly connected to the fixing plate 31 by integral molding or by welding; no specific limitation is made in this embodiment. The mating groove 34 is a rectangular groove. The guide slope 4 is an inclined surface.

[0033] In practical use, when it is necessary to fix the honeycomb ceramic 11 and the foam ceramic 1 together, the honeycomb ceramic 11 is placed in the mounting groove 32. After the honeycomb ceramic 11 is placed in the mounting groove 32, the foam ceramic 1 moves along the mating groove 34 toward the direction closer to the honeycomb ceramic 11. During the movement of foam ceramic 1 towards honeycomb ceramic 11, the guide slope 4 of rotating plate 23 contacts the inner wall of connecting groove 21. As foam ceramic 1 continues to move, rotating plate 23 is subjected to pressure from the inner wall of connecting groove 21. After being subjected to pressure, rotating plate 23 rotates towards mounting plate 22 and compresses multiple springs 24 until mounting plate 22 moves to the bottom of connecting groove 21. At this time, rotating plate 23 no longer contacts the inner wall of connecting groove 21, the pressure on rotating plate 23 disappears, and springs 24 release elastic potential energy. After releasing elastic potential energy, springs 24 push rotating plate 23 to rotate away from mounting plate 22 until rotating plate 23 returns to its initial position. After returning to its initial position, rotating plate 23 fits tightly against the inner wall of connecting groove 21. At this time, rotating plate 23 is completely embedded in connecting groove 21. After rotating plate 23 is embedded in connecting groove 21, a stable connection between foam ceramic 1 and honeycomb ceramic 11 can be achieved.

[0034] Combination Figure 1 In a specific embodiment, the pore size of the foam ceramic 1 is larger than that of the honeycomb ceramic 11. Both the foam ceramic 1 and the honeycomb ceramic 11 are coated with an anti-stick coating. Both the foam ceramic 1 and the honeycomb ceramic 11 have a rectangular structure.

[0035] In the embodiments of this application, the material of the anti-stick coating can be silicon nitride or polytetrafluoroethylene, and no specific limitation is made in the embodiments of this application.

[0036] In practical use, the rectangular arrangement of the foam ceramic 1 and the honeycomb ceramic 11 ensures that they will not rotate relative to each other after being connected. The larger pore size of the foam ceramic 1 compared to the honeycomb ceramic 11 allows the foam ceramic 1 to intercept large particles of impurities during filtration, preventing these particles from clogging the pores of the honeycomb ceramic 11. Furthermore, the anti-stick coating prevents impurities from adhering to the surfaces of the foam ceramic 1 and honeycomb ceramic 11, further preventing clogging of their pores.

[0037] The principle of this embodiment is as follows: When it is necessary to fix the foam ceramic 1 and the honeycomb ceramic 11, the honeycomb ceramic 11 is placed on a horizontal table, and the foam ceramic 1 is placed directly above the honeycomb ceramic 11. After the foam ceramic 1 is placed directly above the honeycomb ceramic 11, vertical pressure is applied to the foam ceramic 1. After the foam ceramic 1 is subjected to pressure, it drives the mounting part 2 to move closer to the honeycomb ceramic 11 until the mounting part 2 is embedded in the honeycomb ceramic 11, thus completing the fixed connection between the foam ceramic 1 and the honeycomb ceramic 11.

[0038] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
