Abstract

The present application discloses a method for detecting the uniformity of openings of high-performance ceramic fillers applied in the field of high-performance ceramics. The method adopts the setting of double filler plates, the filling of nano-sized colored powder and the operation of blowing powder, so that a certain amount of nano-sized powder can be carried through the ceramic filler under the action of wind with a certain flow rate. Since the end face of the ceramic filler away from the air inlet is oiled, the end face has a certain adhesion.

The operation is simple, and can effectively overcome the difficulty of detecting the uniformity of the openings in the prior art.

Description

Technical Field

[0001] The present application relates to the field of high-performance ceramics, and in particular to a method for detecting the uniformity of openings of high-performance ceramic fillers. Background Art

[0002] Ceramic packing has excellent acid and heat resistance, and is resistant to corrosion from various acids and alkalis except oxyfluoric acid. Ceramic packing can be used for linings of scrubbers, cooling towers, recycling towers, desulfurization towers, drying towers, absorption towers, and reactors in the chemical, metallurgical, acid, gas, oxygen, steel, pharmaceutical, and fine chemical industries.

[0003] Ceramic fillers are often used in exhaust gas scrubbing towers to filter small particulate impurities in exhaust gas. Therefore, their porosity and pore uniformity have a great influence on their exhaust gas filtering effect. The lower the porosity, the poorer its adsorption capacity. When the pore uniformity is low, the permeability of the ceramic filler is poor, which not only easily affects the circulation of exhaust gas, but also easily causes the ceramic filler to be damaged due to local uneven force. When ceramic fillers with low pore uniformity are put into use, it is easy to affect the exhaust gas treatment efficiency. Therefore, the pore uniformity test needs to be carried out after leaving the factory. However, due to the relatively fine gaps, the pore uniformity test is difficult. Summary of the Invention

[0004] The present application aims to reduce the difficulty of detecting the uniformity of the openings of ceramic fillers. Compared with the prior art, a method for detecting the uniformity of the openings of high-performance ceramic fillers is provided, which includes the following steps:

[0005] S1. First, prepare the ceramic filler before testing: assemble two ceramic fillers and fill the space between the two ceramic fillers with nano-sized colored powder to obtain a double-filler plate;

[0006] S2. Performing an oiling operation: first, apply clear oil to one end surface of the double-filling plate to make the surface adhesive, and then install the double-filling plate into the double-spherical shell of the fixed plate, so that two spaces are formed between the double-filling plate and the positioning double-spherical shell;

[0007] S3. Perform powder blowing operation: Fill air into the container from the side not coated with clear oil, so that the air drives the nano-sized colored powder through the double packing plate, and some of the nano-sized colored powder is adsorbed on the end surface of the double packing plate on the air outlet side. When obvious nano-sized colored powder is observed on the other side of the double spherical shell of the fixed plate, stop the inflation;

[0008] S4. Take the double-filler plate out of the fixed plate double spherical shell and observe the uniformity of the nano-scale colored powder adhered to the side of the double-filler plate coated with clear oil, and judge the uniformity of the openings based on the uniformity.

[0009] By setting up a double packing plate, coordinating the filling of nano-scale colored powder and the operation of blowing powder, a certain amount of nano-scale powder can be carried through the ceramic packing under the action of wind with a certain flow rate. Since the end face of the ceramic packing away from the air inlet is oiled, the end face has a certain adhesion. At this time, the powder overflowing from the ceramic packing with the wind is partially adsorbed by the clear oil when passing through the end, thereby causing the oiled end face of the ceramic packing to produce an accumulation of nano-scale colored powder, forming an imprint. According to the uniformity of the imprint, the uniformity of the ceramic packing openings can be effectively judged, thereby realizing the detection of the uniformity of the openings on the ceramic packing. The operation is simple, and can effectively overcome the difficulty of detecting the uniformity of the openings in the existing technology.

[0010] Optionally, before performing step S1, the ceramic filler is first pre-treated to dry it so that its interior is dry and it is not easy to produce large adhesion to the nano-scale colored powder, so that some colored powder with nano-scale particle size can pass through the ceramic filler under the action of wind and escape outward, thereby effectively ensuring that some powder can adhere to one side of the oil-coated end of the ceramic filler.

[0011] Optionally, in step S2, when the double filler plate is installed in the double spherical shell of the fixed plate, the two spaces enclosed by the double filler plate and the double spherical shell of the fixed plate are controlled to be independent of each other, so that the two spaces are connected only through the pores in the double filler plate, effectively ensuring that when blowing powder, the colored powder can only pass through the ceramic filler into the space away from the air inlet, so that the detection results are more accurate.

[0012] Optionally, the clear oil includes but is not limited to edible oil and plant essential oil, and the color of the clear oil is light-colored. The color of the nano-scale colored powder is in contrast to the color of the clear oil, so that after the colored powder adheres to the surface of the ceramic filler, an obvious color mark can be produced on the surface of the ceramic filler, and at the same time, the clear oil is not easy to affect the colored mark formed by the colored powder.

[0013] Optionally, in step S4, the oiled end of the double-filler plate after being taken out is printed on white gauze or white paper, thereby imprinting the color mark of the oiled end of the double-filler plate, and judging the uniformity of the opening based on the uniformity of the mark. Judging the uniformity of the opening by the imprinted color mark can reduce the influence of the pores of the ceramic filler itself on the observation of the color mark, so that the observed results can be more accurate in judging the uniformity of the opening.

[0014] At the same time, when making rubbings, pay attention to completing it in one go, and control the double-filling plate to prevent obvious movement after contact with white gauze or white paper, so that the rubbing mark is clearer and the mark is not easily blurred due to friction, effectively ensuring the accuracy of the test results.

[0015] Optionally, the double filler plate includes an outer transparent sleeve, a limiting middle ring fixedly connected to the middle of the outer transparent sleeve, and a ceramic filler placed on the left and right sides of the outer transparent sleeve. The fixed plate double spherical shell includes two transparent hemispherical shells, and the two transparent hemispherical shells are respectively matched with the two ends of the outer transparent sleeve. The nano-scale colored powder is filled in the space surrounded by the two ceramic fillers and the limiting middle ring, and the filling degree of the nano-scale colored powder is 15%-30%, so that the space between the two ceramic fillers is relatively spacious, and it is not easy to block the ceramic filler away from the wind inlet direction, so that it is convenient for it to diffuse in the space and overflow under the action of wind.

[0016] Optionally, a limiting side ring is provided in the transparent hemispherical shell, and the inner diameters of the limiting side ring and the limiting middle ring are both smaller than the diameter of the ceramic filler, effectively limiting the stability of the two ceramic fillers and making them less likely to shift under the action of wind.

[0017] Optionally, a self-coloring rod is fixedly bonded between the two ceramic fillers, and the self-coloring rod includes an outer glass tube and an inner rotating rod movably inserted in the outer glass tube, a plurality of fan blades fixedly connected to the oiled end of the inner rotating rod away from the double filler plate, and a friction head fixedly connected to the end of the inner rotating rod close to the double filler plate, the friction head is wrapped with a satin sheath. During the powder blowing operation, part of the wind force acts on the fan blades, driving the inner rotating rod and the friction head to rotate, causing the satin sheath to generate friction with the inner wall, thereby causing the end surface of the inner rotating rod located at the oiled end away from the wind inlet direction to have static electricity, which can absorb part of the colored powder escaping from the ceramic filler, thereby causing the surface of the outer glass tube to gradually change color, which can promptly remind the working staff to stop the powder blowing operation in time, so that the amount of overflowed colored powder is not too much, and the color mark on the surface of the ceramic filler is not easily affected by the escaped colored powder.

[0018] Optionally, the satin covering is in a fluffy state and contacts the inner wall of the outer glass tube, so that the outer glass tube and the satin covering can rub against each other relatively smoothly, effectively ensuring the generation of static electricity on the surface of the outer glass tube.

[0019] Compared with the existing technology, the advantages of this application are:

[0020] (1) Through the setting of double filler plates, combined with the filling of nano-scale colored powder and the operation of blowing powder, a certain amount of nano-scale powder can be carried through the ceramic filler under the action of wind with a certain flow rate. Since the end face of the ceramic filler away from the air inlet is oiled, the end face has a certain adhesion. At this time, when the powder overflows from the ceramic filler with the wind force passes through the end, part of the powder is adsorbed by the clear oil, and then the end face of the ceramic filler coated with oil produces nano-scale colored powder accumulation, forming an imprint. According to the uniformity of the imprint, the uniformity of the ceramic filler opening can be effectively judged, thereby realizing the detection of the uniformity of the opening on the ceramic filler. The operation is simple and can effectively overcome the difficulty of the conventional technology in detecting the uniformity of the opening.

[0021] (2) Before performing step S1, the ceramic filler is first pre-treated to dry it so that its interior is dry and not easily adhered to the nano-sized colored powder. As a result, part of the colored powder with a nano-sized particle size can pass through the ceramic filler under the action of wind and escape outward, thereby effectively ensuring that part of the powder can adhere to one side of the oil-coated end of the ceramic filler.

[0022] (3) In step S2, when the double filler plate is installed in the double spherical shell of the fixed plate, the two spaces enclosed by the double filler plate and the double spherical shell of the fixed plate are controlled to be independent of each other, so that the two spaces are connected only through the pores in the double filler plate, effectively ensuring that when blowing powder, the colored powder can only pass through the ceramic filler into the space away from the air inlet, so that the detection result is more accurate.

[0023] (4) The clear oil includes but is not limited to edible oil and plant essential oil, and the color of the clear oil is light-colored, and the color of the nano-scale colored powder is in contrast to the color of the clear oil, so that after the colored powder adheres to the surface of the ceramic filler, a clear color mark can be produced on the surface of the ceramic filler, and at the same time, the clear oil is not likely to affect the colored mark formed by the colored powder.

[0024] (5) In step S4, the oiled end of the double-filler plate is printed on white gauze or white paper to create a color imprint of the oiled end of the double-filler plate. The uniformity of the opening is determined based on the uniformity of the imprint. By determining the uniformity of the opening based on the color imprint, the influence of the pores of the ceramic filler itself on the observation of the color imprint can be reduced, making the observed results more accurate in determining the uniformity of the opening.

[0025] (6) Nano-scale colored powder is filled in the space surrounded by two ceramic fillers and the limiting middle ring, and the filling degree of the nano-scale colored powder is 15%-30%, so that the space between the two ceramic fillers is relatively spacious and it is not easy to block the ceramic fillers away from the wind inlet direction, so that it is easy to diffuse in the space and overflow under the action of wind.

[0026] (7) A limiting edge ring is set in the transparent hemispherical shell. The inner diameters of the limiting edge ring and the limiting middle ring are both smaller than the diameter of the ceramic filler, which effectively limits the stability of the two ceramic fillers and makes them less likely to shift under the action of wind.

[0027] (8) During the powder blowing operation, part of the wind force acts on the fan blades, driving the inner rotating rod and the friction head to rotate, causing the satin coating to rub against the inner wall, and then the end surface of the inner rotating rod at the oiled end away from the wind inlet direction is charged with static electricity, which can absorb part of the colored powder escaping from the ceramic filler, and then the surface of the outer glass tube gradually changes color. This can promptly remind the working staff to stop the powder blowing operation in time, so that the amount of colored powder overflowing is not too much, and the color mark on the surface of the ceramic filler is not easily affected by the escaped colored powder.

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] Example 1:

[0041] This application discloses a method for detecting the uniformity of openings of high-performance ceramic fillers. Figure 1 , including the following steps:

[0042] S1, such as Figure 2-3 ,First, the ceramic filler is prepared before testing: two ceramic fillers are assembled and nano-scale colored powder is filled between the two ceramic fillers to obtain a double-filler plate;

[0043] S2, such as Figure 5 In the figure, b represents the oil adhering to the surface of the ceramic filler 11. The oiling operation is performed: first, one side end surface of the double filler plate is coated with clear oil to make the surface adhesive, and then the double filler plate is installed into the double spherical shell of the fixed plate to form two spaces between the double filler plate and the positioning double spherical shell;

[0044] S3, such as Figure 4 In the figure, a represents colored powder, and the powder blowing operation is performed: air is filled into the container from the side that is not coated with clear oil, so that the air drives the nano-sized colored powder to pass through the double packing plate, and some of the nano-sized colored powder is adsorbed on the end surface of the double packing plate on the air outlet side. When obvious nano-sized colored powder is observed on the other side of the double spherical shell of the fixed plate, the inflation is stopped;

[0045] S4, such as Figure 6 In the figure, c represents the part where no obvious mark is formed. The double-filler plate is taken out from the double-spherical shell of the fixed plate, and the uniformity of the nano-scale colored powder adhered to the side of the double-filler plate coated with clear oil is observed. The uniformity of the opening is judged based on the uniformity.

[0046] The part without obvious marks indicates that the pores there are not open holes, or the permeability there is poor. The part with obvious marks indicates that the corresponding position of this part is an open hole. Therefore, the uniformity of the opening can be judged according to the distribution of the marks.

[0047] Before performing step S1, the ceramic filler is first pre-treated to dry it so that its interior is dry and it is not easy to produce large adhesion to the nano-scale colored powder. As a result, part of the colored powder with a nano-scale particle size can pass through the ceramic filler 11 under the action of wind and escape outward, thereby effectively ensuring that part of the powder can adhere to one side of the oil-coated end of the ceramic filler 11.

[0048] In step S2, when the double filler plate is installed in the double spherical shell of the fixed plate, the two spaces enclosed by the double filler plate and the double spherical shell of the fixed plate are controlled to be independent of each other, that is, the connection between the ceramic filler 11 and the outer transparent sleeve 12 is sealed so that the two spaces are connected only through the pores in the double filler plate, effectively ensuring that when blowing powder, the colored powder can only pass through the ceramic filler 11 into the space away from the air inlet, so that the detection results are more accurate.

[0049] The clear oil includes but is not limited to edible oil and plant essential oil, and the color of the clear oil is light-colored. The color of the nano-scale colored powder is in contrast to the color of the clear oil. After the colored powder adheres to the surface of the ceramic filler 11, an obvious color mark can be produced on the surface of the ceramic filler 11, and at the same time, the clear oil is not easy to affect the colored mark formed by the colored powder.

[0050] In step S4, the oiled end of the double-filler plate after being taken out is printed on white gauze or white paper, so as to print the color imprint of the oiled end of the double-filler plate. The uniformity of the opening is judged according to the uniformity of the imprint. Judging the uniformity of the opening by the imprinted color imprint can reduce the influence of the pores of the ceramic filler 11 itself on the observation of the color imprint, so that the observed results can be more accurate in judging the uniformity of the opening.

[0051] At the same time, when making rubbings, pay attention to completing it in one go, and control the double-filling plate to prevent obvious movement after contact with white gauze or white paper, so that the rubbing mark is clearer and the mark is not easily blurred due to friction, effectively ensuring the accuracy of the test results.

[0052] See also Figure 3 The double filler plate includes an outer transparent sleeve 12, a limiting middle ring 13 fixedly connected to the middle of the outer transparent sleeve 12, and a ceramic filler 11 placed on the left and right sides of the outer transparent sleeve 12. The fixed plate double spherical shell includes two transparent hemispherical shells 2, and the two transparent hemispherical shells 2 are respectively matched with the two ends of the outer transparent sleeve 12. Nano-scale colored powder is filled in the space surrounded by the two ceramic fillers 11 and the limiting middle ring 13, and the filling degree of the nano-scale colored powder is 15%-30%, so that the space between the two ceramic fillers 11 is relatively spacious, and it is not easy to block the ceramic filler 11 away from the wind inlet direction, so that it is convenient to diffuse in the space and overflow under the action of wind.

[0053] Optionally, a limiting side ring is provided in the transparent hemispherical shell 2, and the inner diameters of the limiting side ring and the limiting middle ring 13 are both smaller than the diameter of the ceramic filler 11, effectively limiting the stability of the two ceramic fillers 11, making them less likely to shift under the action of wind.

[0054] Example 2:

[0055] See also Figure 7-8 The two ceramic fillers 11 are fixedly bonded with a self-coloring rod 3, which includes an outer glass tube 31 and an inner rotating rod 32 movably inserted in the outer glass tube 31, a plurality of fan blades 4 fixedly connected to the end of the inner rotating rod 32 away from the oiling end of the double filler plate, and a friction head 33 fixedly connected to the end of the inner rotating rod 32 close to the double filler plate. The friction head 33 is wrapped with a satin cladding 5. Figure 9 The dotted arrow in the figure indicates rotation. During the powder blowing operation, part of the wind force acts on the fan blade 4, driving the inner rotating rod 32 and the friction head 33 to rotate, causing the satin cladding 5 to rub against the inner wall of 51, and then the end surface of the inner rotating rod 32 located at the oiled end away from the wind inlet direction has static electricity, which can absorb part of the colored powder escaping from the ceramic filler 11, and then the surface of the outer glass tube 31 gradually changes color, which can promptly remind the working staff to stop the powder blowing operation in time, so that the amount of colored powder overflowing is not too much, and the color mark on the surface of the ceramic filler 11 is not easily affected by the escaped colored powder.

[0056] The satin covering 5 is in a fluffy state and contacts the inner wall of the outer glass tube 31 , so that the outer glass tube 31 and the satin covering 5 can rub against each other relatively smoothly, effectively ensuring the generation of static electricity on the surface of the outer glass tube 31 .

[0057] By setting up a double filler plate, coordinating the filling of nano-scale colored powder and the operation of blowing powder, a certain amount of nano-scale powder can be carried through the ceramic filler 11 under the action of wind with a certain flow rate. Since the end face of the ceramic filler 11 away from the air inlet is oiled, the end face has a certain adhesion. At this time, the powder overflowing from the ceramic filler 11 with the wind is partially adsorbed by the clear oil when passing through the end, thereby causing the oiled end face of the ceramic filler 11 to produce an accumulation of nano-scale colored powder, forming an imprint. According to the uniformity of the imprint, the uniformity of the openings of the ceramic filler 11 can be roughly judged, thereby realizing the detection of the uniformity of the openings on the ceramic filler 11. The operation is simple, and can effectively overcome the difficulty of detecting the uniformity of the openings in the prior art.

[0058] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed in the present application based on the technical solution and its improved ideas, which should be covered by the scope of protection of the present application.
