Description

Technical Field

[0001] The invention relates to the technical field of component detection, and in particular to a honeycomb ceramic filter body air permeability detection device. Background Art

[0002] Honeycomb ceramics are a kind of porous ceramic materials, which are widely used in the fields of catalyst carriers, filters, thermal insulation materials, oxide electrolytes, etc., especially in the field of motor vehicle exhaust treatment. In terms of automobile exhaust purification, porous ceramics (especially honeycomb ceramics) are used as carriers, and the surface is coated with a catalyst made of a composite of precious metals, rare earth elements, transition metals, etc. This catalyst can catalyze the decomposition of harmful components such as CO, HC, NOx in automobile exhaust and turn them into harmless gases such as CO2, H2O and N2, thereby meeting the national emission standards.

[0003] The porosity permeability of honeycomb ceramics refers to the percentage of the volume of the pore part in the porous material to the total volume of the material. This parameter is the most important characteristic of porous ceramic materials. Higher apparent porosity usually means better permeability, which is especially important for applications that require gas exchange. Therefore, it is necessary to test the porosity permeability of honeycomb ceramics. At present, the permeability detection technologies of porous ceramics mainly include drainage method, gas adsorption method, small angle scattering method and thermal porosimeter method.

[0004] Among them, the drainage method (based on the Archimedean principle) is a commonly used method for detecting the apparent porosity of porous ceramics. Generally, the dry mass of the pores of the honeycomb ceramic sample before immersion in water and the saturated mass of the pores after immersion in water are measured, and then the apparent porosity of the honeycomb ceramic is calculated according to the density of the immersion liquid. However, the total pores of the honeycomb ceramic are divided into effective pores and invalid pores. Effective pores refer to the proportion of pores that are interconnected and allow fluid to flow therein, while invalid pores refer to the proportion of pores that are not connected and blocked.

[0005] During the displacement method measurement, when the sample is suspended in the liquid and reaches the saturated mass, both the effective pores and the invalid pores will be filled with water. Since the displacement method calculates the porosity by measuring the volume of water displaced by the sample in the water, it cannot directly distinguish between effective pores and invalid pores, which will cause the effective porosity result obtained from the test to be too large, making it difficult to obtain high-precision porosity measurement results. Summary of the invention

[0006] The purpose of the present invention is to solve the problem in the prior art that effective and ineffective pores cannot be distinguished, resulting in a larger effective porosity result obtained by testing, and to propose a honeycomb ceramic filter air permeability testing device.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

The air outlet end of the blower is fixedly connected with a corrugated pipe, and the other end of the corrugated pipe is fixedly connected with a heat storage cylinder. The outer wall of the heat storage cylinder is fixedly connected with a support plate, and the outer walls on both sides of the support plate are in sliding fit with the inner wall of the detection box body. The bottom of the heat storage cylinder is fixedly connected with a heating plate. Driving motors are symmetrically and fixedly installed on the top inner wall of the detection box body, and one end output shaft of the driving motor is fixedly connected with a driving rod. A threaded rod is arranged in a fitting manner on the outer wall of the driving rod, and the outer wall of the threaded rod is in threaded connection with the inside of the support plate.

[0013] Furthermore, a rotating groove is provided in the inner wall of the threaded rod, and the threaded rod is rotationally connected with the outer wall of the driving rod through the rotating groove. A groove is provided in the inner wall of the rotating groove, and engaging grooves are equidistantly provided in the inner wall of the groove. Rubber tooth rows are equidistantly fixedly connected to the outer wall of the driving rod corresponding to the engaging grooves, and the outer wall of the rubber tooth row is meshed and connected to the inner wall of the engaging groove. First ventilation holes are symmetrically penetrated through the outer wall of the heat storage cylinder corresponding to the knocking liquid cleaning component.

[0014] Furthermore, the knocking liquid cleaning component includes a movable disc, and an annular groove is provided inside the movable disc. Second ventilation holes are symmetrically penetrated through the top of the movable disc, and connecting hoses are fixedly connected to the top of the movable disc corresponding to the second ventilation holes. The other ends of the connecting hoses are fixedly connected to the outer wall of the heat storage cylinder corresponding to the first ventilation holes. The inside of the heat storage cylinder is communicated with the annular groove through the connecting hoses, and a rotating ring is slidably connected to the bottom inner wall of the annular groove. Guide inclined plates are equidistantly fixedly connected to the top of the rotating ring.

[0015] Furthermore, through grooves are equidistantly formed in the inner wall of the movable disc in a penetrating manner, and a knocking rod is slidably connected to the inner wall of the through groove in a fitting manner. A fixing block is fixedly connected to one end of the knocking rod away from the honeycomb ceramic body, and the outer walls on the upper and lower sides of the fixing block are slidably fitted to the inner wall of the annular groove. A return spring is disposed in a fitting manner on the outer wall of the knocking rod.

[0016] Furthermore, one end of the return spring is fixedly connected to the outer wall of the fixing block facing the honeycomb ceramic body, and the other end of the return spring is fixedly connected to the inner wall of the annular groove.

[0019] Compared with the prior art, the above solution has the following beneficial effects:

[0020] 1. During the detection, the honeycomb ceramic body can be heated and warmed up by the heating disc, so that the solidified resin in the through pores at both ends of the honeycomb ceramic body melts and flows out from the other end, while the non-through closed pores retain the melted resin solution in the honeycomb ceramic body. By measuring the volume of the flowing-out solution and the volume of the solution remaining in the honeycomb ceramic, the volume ratio of the open pores to the closed pores can be calculated, and then the effective pores and ineffective pores can be accurately distinguished, thereby providing more accurate porosity information.

[0021] 2. During the detection, through the cooperation of the connecting hose and the guiding inclined plate, multiple knocking rods surrounding the outer side of the honeycomb ceramic body can be driven to knock on its outer wall, so as to accelerate the discharging efficiency of the solution in the through pores at both ends, and avoid partial solution staying in the concave positions in the pores, resulting in being unable to be heated and flowed out or being difficult to be heated and flowed out, ensuring the total amount of the discharged solution, and further ensuring the subsequent measurement results and improving the result accuracy.

[0022] 3. When conducting the detection, through the cooperation of the connecting rod and the annular inclined groove, the movable disk can be continuously driven to move up and down outside the honeycomb ceramic body, so as to more evenly knock on the outside of the honeycomb ceramic body, and the hot air can be evenly blown on the outside of the honeycomb ceramic body through multiple through grooves, ensuring the full flow and melting of the solution in the pores, more effectively discharging the solution in the phase-through pores, reducing the residue amount, and thus improving the accuracy of the measurement results.

Specific embodiments

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

In addition, the terms "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not require or imply any actual relationship, order or relative importance between these entities or operations.

[0033] Embodiment 1:

[0034] Refer to Figure 1-7 , a honeycomb ceramic filter body air permeability detection device, including a detection box body 1 and a honeycomb ceramic main body 2. A positioning groove 3 is provided on the bottom inner wall of the detection box body 1 corresponding to the honeycomb ceramic main body 2, and a collection groove 4 is provided on the inner wall of the positioning groove 3.

[0035] Further, a heat-melting liquid drainage component 5 is arranged on the inner wall of the detection box body 1. The heat-melting liquid drainage component 5 includes a fan 501, and the bottom of the fan 501 is fixedly installed on the top of the detection box body 1. The air outlet end of the fan 501 is fixedly connected with a corrugated pipe 502, and the other end of the corrugated pipe 502 is fixedly connected with a heat storage cylinder 503. The outer wall of the heat storage cylinder 503 is fixedly connected with a support plate 504, and the outer walls on both sides of the support plate 504 are in sliding fit with the inner wall of the detection box body 1. The bottom of the heat storage cylinder 503 is fixedly connected with a heating plate 505. The driving motors 506 are symmetrically and fixedly installed on the inner wall of the top of the detection box body 1, and one end output shaft of the driving motor 506 is fixedly connected with a driving rod 507. The outer wall of the driving rod 507 is fitted with a threaded rod 508, and the outer wall of the threaded rod 508 is in threaded connection with the inside of the support plate 504.

[0036] In the embodiment, before placing it into the detection box body 1, first, the honeycomb ceramic body 2 itself is accurately weighed, and its initial weight is recorded. Then, one end of the honeycomb ceramic body 2 is immersed in a suitable solution, such as a low-viscosity resin solution, to ensure that the resin solution can completely enter the pores of the honeycomb ceramic body 2 from one end, and the other end is flush with the liquid level of the solution. Wait for the solution to solidify in the pores to fix the pore structure. Then, when it is not completely hardened, the honeycomb ceramic body 2 is taken out of the solution. This usually requires waiting for a period of time at room temperature to allow the resin to partially cure so that it can maintain its shape and not flow easily. Subsequently, the excess cured resin in the pores is removed, and then weighed to obtain the total weight after the resin remains in the pores.

[0037] Then, the honeycomb ceramic body 2 can be placed in the positioning groove 3 in the detection box body 1, placed vertically, and the end of the honeycomb ceramic body 2 immersed in the solution faces upward. Then, the outer wall of the heat storage cylinder 503 is fixedly connected with a support plate 504, and the outer walls on both sides of the support plate 504 are in sliding fit with the inner wall of the detection box body 1. At the same time, one end output shaft of the driving motor 506 is fixedly connected with a driving rod 507. The outer wall of the driving rod 507 is fitted with a threaded rod 508, and the outer wall of the threaded rod 508 is in threaded connection with the inside of the support plate 504. The inner wall of the threaded rod 508 is provided with a rotating groove 509, and the threaded rod 508 is rotationally connected with the outer wall of the driving rod 507 through the rotating groove 509. The inner wall of the rotating groove 509 is provided with a groove 510, and the inner wall of the groove 510 is equidistantly provided with meshing grooves 511. The outer wall of the driving rod 507 is equidistantly fixedly connected with rubber tooth rows 512 corresponding to the meshing grooves 511, and the outer wall of the rubber tooth rows 512 is meshed with the inner wall of the meshing grooves 511. Thus, the driving rod 507 can be driven to rotate by the driving motor 506. Since the rubber tooth rows 512 are meshed with the meshing grooves 511 of the threaded rod 508, the threaded rod 508 can be synchronously driven to rotate, and then the support plate 504 can be driven to descend by using the thread.

[0038] Then, a heating plate 505 is fixedly connected to the bottom of the heat storage cylinder 503. Thus, when the support plate 504 drives the heat storage cylinder 503 to descend, first, the heating plate 505 located at the bottom of the heat storage cylinder 503 will contact and press-fix with the top of the honeycomb ceramic body 2. Then, a bellows 502 is fixedly connected to the air outlet end of the blower 501, and the other end of the bellows 502 is fixedly connected to the heat storage cylinder 503. Thus, the blower 501 can send hot air into the heat storage cylinder 503 through the bellows 502 to heat the heating plate 505. Furthermore, the heating plate 505 that fits with the honeycomb ceramic body 2 can be used to heat and raise its temperature. At this time, as the temperature of the honeycomb ceramic body 2 itself rises, the cured resin in its pores will melt accordingly. At this time, the solidified resin in the through pores at both ends of the honeycomb ceramic body 2 will melt and flow out from the bottom of the honeycomb ceramic body 2 under the influence of gravity and flow into the collection tank 4.

[0039] Then, since the resin solution in the closed pores cannot flow out from the other end, it will continue to remain in the honeycomb ceramic body 2. After the heating is completed, the resin solution remaining in the honeycomb ceramic body 2 is taken out. At this time, the total volume of the open pores of the honeycomb ceramic body 2 and the volume of the closed pores at one end of the honeycomb ceramic body 2 can be obtained. At this time, by repeating the above steps and immersing the other end of the honeycomb ceramic body 2 in the resin solution, the volume of the closed pores at both ends of the honeycomb ceramic body 2 can be obtained. Thus, the volume ratio of the open pores to the closed pores can be calculated, and furthermore, the effective pores and ineffective pores can be accurately distinguished, providing more accurate porosity information.

[0040] Furthermore, a knocking and liquid-clearing component 6 is arranged inside the detection box 1. The knocking and liquid-clearing component 6 includes a movable disk 601. A ring groove 602 is formed inside the movable disk 601. Second ventilation holes 603 are symmetrically formed through the top of the movable disk 601. A connecting hose 604 is fixedly connected to the top of the movable disk 601 corresponding to the second ventilation holes 603. The other end of the connecting hose 604 is fixedly connected to the outer wall of the heat storage cylinder 503 corresponding to the first ventilation hole 513. The inside of the heat storage cylinder 503 is communicated with the ring groove 602 through the connecting hose 604. A rotating ring 605 is slidably connected to the bottom inner wall of the ring groove 602. Guide inclined plates 606 are fixedly connected to the top of the rotating ring 605 at equal intervals.

[0041] In the embodiment, since each of the interconnected pores is not a smooth and straight-through pore, there may be concave and convex points in the entire pore channel, which may cause the pores to be unable or difficult to be melted and discharged. Therefore, on this basis, an annular groove 602 is formed inside the movable disk 601, and second ventilation holes 603 are symmetrically formed through the top of the movable disk 601. A connecting hose 604 is fixedly connected to the top of the movable disk 601 corresponding to the second ventilation holes 603. At the same time, the other end of the connecting hose 604 is fixedly connected to the outer wall of the heat storage cylinder 503 corresponding to the first ventilation hole 513. The inside of the heat storage cylinder 503 is connected to the annular groove 602 through the connecting hose 604. Thus, when the blower 501 heats the heating disk 505, the hot air therein can be transported into the annular groove 602.

[0042] At this time, a rotating ring 605 is slidably connected to the inner wall of the bottom of the annular groove 602, and guiding inclined plates 606 are fixedly connected to the top of the rotating ring 605 at equal intervals. Thus, when the hot air is blown into the annular groove 602, the shape of the guiding inclined plates 606 can be utilized to drive the rotating ring 605 to rotate by relying on the wind force. At this time, through grooves 607 are formed through the inner wall of the movable disk 601 at equal intervals, and a knocking rod 608 is slidably connected to the inner wall of the through groove 607. One end of the knocking rod 608 away from the honeycomb ceramic body 2 is fixedly connected to a fixing block 609. At the same time, the outer walls on the upper and lower sides of the fixing block 609 are in sliding contact with the inner wall of the annular groove 602. A return spring 610 is disposed in contact with the outer wall of the knocking rod 608. At the same time, contact blocks 611 are fixedly connected to the inner wall of the rotating ring 605 at equal intervals corresponding to the fixing block 609. The outer shape of the contact blocks 611 is an isosceles triangle. Thus, when the rotating ring 605 rotates, a plurality of contact blocks 611 can be synchronously driven to move in a circular motion. Furthermore, the fixing block 609 can be guided and pushed by the inclined plane, so that the fixing block 609 drives the knocking rod 608 to move and collide in the direction of the honeycomb ceramic body 2, thereby accelerating the discharge efficiency of the solution in the pores with through holes at both ends and avoiding part of the solution staying in the concave positions in the pores.

[0043] Furthermore, since the heating disk 505 is pressed and fitted on the top of the honeycomb ceramic body 2, it is possible to prevent the solution in the closed pores from splashing into the interconnected pores during the knocking and vibration process of the honeycomb ceramic body 2, ensuring the accuracy of the results.

[0044] Furthermore, a moving auxiliary component 7 is arranged on the inner wall of the detection box body 1. The moving auxiliary component 7 includes a connecting rod 701. The closer ends of the two connecting rods 701 are fixedly connected to the outer wall of the movable disc 601. A sliding rod 702 is fitted and slidably connected inside the connecting rod 701. The bottom of the sliding rod 702 is fixedly connected to the bottom inner wall of the detection box body 1. A connecting column 703 is fixedly connected to the bottom of the driving rod 507. The bottom of the connecting column 703 is rotatably connected to the bottom inner wall of the detection box body 1. An annular inclined groove 704 is formed in the outer wall of the connecting column 703 corresponding to the connecting rod 701. The farther ends of the two connecting rods 701 are fitted and slidably connected to the inner wall of the annular inclined groove 704.

[0045] In the embodiment, first, since the rubber tooth row 512 is engaged with the meshing groove 511 of the threaded rod 508, the threaded rod 508 can be synchronously driven to rotate. When the heating plate 505 at the bottom of the heat storage cylinder 503 contacts and presses against the top of the honeycomb ceramic body 2 to be fixed, at this time, the rubber tooth row 512 will be engaged with the meshing groove 511 of the threaded rod 508 to drive the pressure to gradually increase. Thus, when the heating plate 505 contacts and presses against the top of the honeycomb ceramic body 2 to a certain extent, the rubber tooth row 512 will deform, and through the reserved groove 510, the rubber tooth row 512 will skip teeth, that is, while keeping the heating plate 505 in contact with and pressing against the top of the honeycomb ceramic body 2, the driving motor 506 can still drive the driving rod 507 to continue rotating.

[0046] At this time, since the closer ends of the two connecting rods 701 are fixedly connected to the outer wall of the movable disc 601, a sliding rod 702 is fitted and slidably connected inside the connecting rod 701, a connecting column 703 is fixedly connected to the bottom of the driving rod 507, an annular inclined groove 704 is formed in the outer wall of the connecting column 703 corresponding to the connecting rod 701, and the farther ends of the two connecting rods 701 are fitted and slidably connected to the inner wall of the annular inclined groove 704, the two connecting columns 703 can be driven to rotate by the driving rod 507. Furthermore, with the cooperation of the connecting rod 701 and the annular inclined groove 704, the movable disc 601 can move up and down outside the honeycomb ceramic body 2, so that the outer side of the honeycomb ceramic body 2 can be knocked more evenly, and the outer surface of the honeycomb ceramic body 2 can be prevented from being damaged due to continuous knocking at the same position.

[0047] Further, a knocking rod 608 is slidably connected to the inner wall of the through groove 607 in a fitting manner. However, the inner wall of the through groove 607 and the outer wall of the knocking rod 608 are not completely sealed, so that the hot air introduced into the movable disk 601 can be ejected from the through groove 607. Thus, during the lifting and lowering process of the movable disk 601, the hot air is evenly blown outside the honeycomb ceramic body 2 through a plurality of through grooves 607, ensuring the full flow and melting of the solution in the pores, more effectively discharging the solution in the through pores, reducing the residue amount, and thus improving the accuracy of the measurement result.

[0048] The working principle of the present invention is as follows: First, after weighing the weight of the honeycomb ceramic body 2 before immersion in the liquid and the total weight after the resin remains in the pores, the honeycomb ceramic body 2 is placed in the positioning groove 3 in the detection box body 1, placed vertically, and the end of the honeycomb ceramic body 2 immersed in the solution faces upward. Then, the driving rod 507 is driven to rotate by the driving motor 506. Since the rubber tooth row 512 meshes with the engaging groove 511 of the threaded rod 508, the threaded rod 508 can be synchronously driven to rotate, and then the support plate 504 can be driven to descend by using the thread.

[0049] At this time, the heating plate 505 at the bottom of the heat storage cylinder 503 will contact and press-fix the top of the honeycomb ceramic body 2. Then, the hot air is sent into the heat storage cylinder 503 through the corrugated pipe 502 by the blower 501 to heat the heating plate 505. Furthermore, the honeycomb ceramic body 2 can be heated and raised in temperature by using the heating plate 505 in contact with the honeycomb ceramic body 2. At this time, as the temperature of the honeycomb ceramic body 2 itself rises, the cured resin in its pores will melt accordingly. At this time, the solidified resin in the through pores at both ends of the honeycomb ceramic body 2 will melt and flow out from the bottom of the honeycomb ceramic body 2 under the influence of gravity and flow into the collection tank 4.

[0050] Next, since the resin solution in the closed pores cannot flow out from the other end, it will continue to remain in the honeycomb ceramic body 2. After the heating is completed, the resin solution remaining in the honeycomb ceramic body 2 is taken out. At this time, the total volume of the open pores of the honeycomb ceramic body 2 and the volume of the closed pores at one end of the honeycomb ceramic body 2 can be obtained. At this time, by repeating the above steps to immerse the other end of the honeycomb ceramic body 2 in the resin solution, the volume of the closed pores at both ends of the honeycomb ceramic body 2 can be obtained, so that the volume ratio of the open pores to the closed pores can be calculated, and thus the effective pores and ineffective pores can be accurately distinguished.

[0051] Next, when the heating disk 505 is heated by the fan 501, the hot air therein can be conveyed into the annular groove 602. When the hot air is conveyed into the annular groove 602, the shape of the guiding inclined plate 606 can be utilized to drive the rotating ring 605 to rotate by relying on the wind force. Thus, when the rotating ring 605 rotates, a plurality of contact blocks 611 can be synchronously driven to move in a circular motion. Furthermore, the inclined surface can be utilized to guide and push the fixed block 609, so that the fixed block 609 drives the knocking rod 608 to move and collide in the direction of the honeycomb ceramic body 2, thereby accelerating the discharging efficiency of the solution in the through holes at both ends and avoiding partial solution staying in the concave positions in the pores.

[0052] Next, the driving rod 507 drives the two connecting columns 703 to rotate. Furthermore, under the cooperation of the connecting rod 701 and the annular inclined groove 704, the movable disk 601 moves up and down on the outer side of the honeycomb ceramic body 2, so that the outer side of the honeycomb ceramic body 2 can be knocked more evenly, and continuous knocking at the same position is avoided, which may damage the outer surface of the honeycomb ceramic body 2. At the same time, the inner wall of the through groove 607 and the outer wall of the knocking rod 608 are not completely sealed, so that the hot air introduced into the movable disk 601 can be ejected from the through groove 607. Thus, during the up and down movement of the movable disk 601, the hot air is evenly blown on the outer side of the honeycomb ceramic body 2 through a plurality of through grooves 607, ensuring the full flow and melting of the solution in the pores and more effectively discharging the solution in the through pores and reducing the residue amount.

[0053] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be subject to the scope defined by the claims.
