Description

Technical Field

[0001] The present invention belongs to the technical field of filter material preparation, and specifically relates to a preparation method of a water-poisoning-resistant dust removal and denitrification integrated filter material. Background Art

[0002] The water-poisoning-resistant dust removal and denitrification integrated filter material is a high-performance air filtration material, aiming to simultaneously achieve the functions of dust removal and denitrification, and has the characteristics of water resistance and anti-poisoning. It is a technical product integrating the functions of dust removal and denitrification catalysis. The denitrification catalyst is loaded onto the dust removal filter material in the form of a finished product or a precursor, so as to carry out the coordinated treatment of dust removal and denitrification. This filter material can not only effectively filter particulate matter in the air, but also catalytically decompose nitrogen oxides, achieving the dual effects of dust removal and denitrification. At the same time, it also has the ability of water resistance and anti-poisoning, and can maintain stable filtration performance in a humid or harmful substance-containing environment.

[0003] In the existing process of preparing the water-poisoning-resistant dust removal and denitrification integrated filter material, in the face of the preparation of the catalytic filter membrane, it is necessary to mix and stir the prepared mixed slurry with a certain amount of binder. However, due to the certain viscosity of the mixed slurry, and the binder with better mixing effect with the slurry, such as polyvinyl butyral, generally presents as granular powder, and is covered on the top surface of the mixed slurry by pouring from above, and combined with the existing single stirring method to achieve the mixing of the two. This way of pouring the binder from top to bottom easily causes the deeper areas of the mixed slurry to not be fully mixed with the binder, resulting in a worse mixing degree. Therefore, it needs to be improved. Summary of the Invention

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] like Figures 1 to 11 As shown, the present invention provides a method for preparing a water poisoning-resistant dust removal and denitrification integrated filter material, and the preparation method is as follows:

[0045] S1. Initial preparation of catalytic membrane: Mix and dissolve the raw materials and ball-mill to obtain a mixed slurry, add a binder to the mixed slurry by using a stirring and mixing device, and then stir, dry, grind and granulate to obtain a support body, then mix the mixed coating liquid with the support body, dry, calcine, and cool to obtain a microfiltration membrane;

[0046] S2. Later preparation of catalytic filter membrane: immersing the mixed precursor solution in a silica fiber-based membrane, allowing it to stand, and obtaining a cobalt titanate composite silica catalytic separation membrane after air calcination, and adding the prepared carbon nanotube raw material to a solvent for flocculation treatment to obtain a filter membrane;

[0047] S3, hot pressing compounding and washing treatment: hot pressing compounding is used to make the pretreated filter material base cloth and the filter membrane obtained in S2 fit tightly together, and then assembled to obtain a water-poisoning-resistant dust removal and denitrification integrated filter material, and the prepared water-poisoning-resistant dust removal and denitrification integrated filter material is washed and dried.

[0048] A preparation device for a water poisoning-resistant dust removal and denitrification integrated filter material, wherein the stirring and mixing device in S1 includes a mixing bin 1, and further includes:

[0049] A rotating shaft 3, the rotating shaft 3 is rotatably connected to the interior of the mixing chamber 1;

[0050] The moving module 2 is arranged in the inner cavity of the rotating shaft 3, and the bottom thereof is abutted and connected with the movable module 4;

[0051] An extrusion module 5, which is fixed to both sides of the upper end of the rotating shaft 3;

[0052] The toggle assembly 6 is fixedly mounted on both sides of the rotating shaft 3 and is engaged with the moving module 2;

[0053] The rotating shaft 3 includes a shaft body 31, and the shaft body 31 is arranged at the central end of the inner cavity of the mixing bin 1; the moving module 2 includes a moving plate 22, which is movably connected to the inner cavity of the rotating shaft 3, and a number of protrusions 23 are equidistantly installed on both sides of the lower end of the moving plate 22; the extrusion module 5 includes a material storage pipe 51, and a push rod 55 is movably connected inside the material storage pipe 51, and a material discharge trough 53 is opened at the upper end of the inner cavity of the material storage pipe 51, and a material discharge pipe 54 is installed at the opening of the material discharge trough 53 at one end inside the rotating shaft 3.

[0054] like Figure 1 As shown, the mixing bin 1 comprises a shell 11, a cover plate 13 is provided at the top end of the shell 11, and a bottom plate 12 is bolted to the bottom end of the shell 11;

[0055] The outer wall of the housing 11 is provided with a plurality of groups of legs, wherein the top surfaces of two groups of symmetrical legs are mounted with electric telescopic cylinders 7 , and the tops of the electric telescopic cylinders 7 are fixedly connected to the bottom surface of the cover plate 13 .

[0056] The above scheme is adopted: when the electric telescopic cylinder 7 is running, the top end of the electric telescopic cylinder 7 pushes the cover plate 13 upward, so that the cover plate 13 gradually releases the fitting state with the shell 11. At this time, the contact area between the cover plate 13 and the shell 11 will present a larger spacing area, and the operator can pour the mixed slurry into the inner cavity of the shell 11. After pouring, the electric telescopic cylinder 7 is started again to drive the cover plate 13 downward, and the connection between the cover plate 13 and the shell 11 is realized again to cover the top of the shell 11; at the same time, the bottom plate 12 is connected with the shell 11 by bolts. When the preparation is completed, the bottom plate 12 is released from the bottom surface of the shell 11 by twisting the bolts between the bottom plate 12 and the shell 11, so that the operator can take out the material.

[0057] like Figure 3 As shown, a servo motor 33 is connected to the top of the shaft body 31 , and the output shaft of the servo motor 33 extends to the inside of the shaft body 31 . The servo motor 33 is fixed to the cover plate 13 , and two groups of stirring blades 32 are installed at equal angles in a ring on the upper side of the outer wall of the shaft body 31 .

[0058] Adopting the above solution: When the servo motor 33 operates and drives the shaft body 31 to rotate in the inner cavity of the housing 11, simultaneously, it will cause the stirring blade 32 to rotate in the same direction in the inner cavity of the housing 11.

[0059] As Figure 7 and Figure 8 shown, the output shaft of the servo motor 33 is in a "one" shape, and a notch adapted to the output shaft of the servo motor 33 is provided in the connection area between the top of the shaft body 31 and the output shaft of the servo motor 33.

[0060] Adopting the above solution: When the electric telescopic cylinder 7 gradually moves the cover plate 13 upward relative to the housing 11, the output shaft of the servo motor 33 will disengage from the notch of the shaft body 31. When it is necessary to make the shaft body 31 rotate, when the electric telescopic cylinder 7 drives the servo motor 33 to move downward, the output shaft of the servo motor 33 will tightly engage in the notch of the shaft body 31. Then, when the servo motor 33 operates, due to the "one" shape design of its output end, it will smoothly drive the shaft body 31 to rotate.

[0061] As Figure 3 and Figure 4 shown, a pneumatic cylinder 21 is fixedly connected to the top of the moving plate 22, the pneumatic cylinder 21 is fixedly installed on the top surface of the shaft body 31, and the side wall of the convex block 23 abuts against the movable module 4;

[0062] The upper end of the moving plate 22 is in the shape of a frustum of a cone with a "wider upper part and narrower lower part" and is in contact connection with the push rod 55. When the moving plate 22 moves downward.

[0063] Adopting the above solution: Due to the fixing effect between the storage pipe 51 and the shaft body 31, the frustum-shaped upper end of the storage pipe 51 will gradually abut against the push rod 55, causing the push rod 55 to be forced to move gradually into the interior of the storage pipe 51.

[0064] As Figure 4 、 Figure 5 and Figure 8 shown, the movable module 4 includes a first baffle 41. Both ends of the first baffle 41 are respectively located inside and outside the shaft body 31. The first baffle 41 located inside the inner cavity of the shaft body 31 is rotatably connected to the inner cavity of the shaft body 31. One end of the first baffle 41 located outside the inner cavity of the shaft body 31 is hinged to a second baffle 44, and the end of the second baffle 44 far from the first baffle 41 is hinged to the top surface of the bottom plate 12.

[0065] As Figure 4 and Figure 8 shown, an arc-shaped spring 42 is installed at one end of the first baffle 41 located inside the inner cavity of the shaft body 31. The top of the arc-shaped spring 42 is fixedly connected to the inner cavity of the shaft body 31. Folding rubber baffles 43 are connected to both the upper and lower sides of the connection area between the middle of the first baffle 41 and the shaft body 31. The end of the first baffle 41 far from the second baffle 44 abuts against the convex block 23. ​

[0066] Adopting the above solution: when the moving plate 22 drives the convex block 23 to move downward, the end of the convex block 23 will abut against the first baffle 41, causing the first baffle 41 to flip and rotate. At this time, the first baffle 41 will cause the end of the second baffle 44 close to the first baffle 41 to tilt upward, that is, the second baffle 44 changes from a horizontal state to an inclined state. At this time, the upper and lower folding rubber baffles 43 in the connection area between the middle end of the first baffle 41 and the shaft body 31 will change synchronously. That is, the folding rubber baffle 43 located above is compressed, and the folding rubber baffle 43 located below is stretched. The design of the folding rubber baffle 43 prevents the slurry inside the shaft body 31 from penetrating into the inside of the shaft body 31 through the connection area between the first baffle 41 and the shaft body 31 during the operation of the device, playing a protective role.

[0067] As Figure 6 、 Figure 8 and Figure 9 As shown in

[0068] Both the upper and lower sides of the end of the storage pipe 51 far from the push rod 55 are provided with discharge holes 52, and the push rod 55 is elastically connected to the storage pipe 51 through a first spring 56;

[0069] A block for preventing the push rod 55 from continuously entering the inside of the storage pipe 51 is installed at one end of the push rod 55 located outside the storage pipe 51. Figure 8 and Figure 10 As shown in

[0070] The adjacent ends of the two J-shaped rods 61 are distributed in a crossed shape, and the contact ends of the two J-shaped rods 61 are on the same horizontal plane as the discharge holes 52.

[0071] The working principle and usage process of the present invention:

[0072] First, the electric telescopic cylinder 7 is used to push up the cover plate 13 to increase the interval between the cover plate 13 and the housing 11, allowing the operator to pour the mixed slurry into the inside of the housing 11. Then, the electric telescopic cylinder 7 is started again to make it lower the servo motor 33 through the cover plate 13, and the output shaft of the servo motor 33 is stuck in the slot on the top surface of the shaft body 31. A certain amount of binder is poured into the two feeding pipes 54 in two parts respectively, and enters the feeding groove 53 through the feeding pipes 54, and then the binder fills the area near the discharge holes 52 in the inner cavity of the storage pipe 51 through the opening of the feeding groove 53;

[0073] After that, the air cylinder 21 is activated to drive the moving plate 22 to move downward. During the downward movement of the moving plate 22, the outer wall of the upper end in the shape of a frustum of a cone will first contact the push rod 55, causing the push rod 55 to gradually move inside the storage pipe 51, and pushing the adhesive inside the storage pipe 51 to be discharged into the inside of the shaft body 31 through the discharge hole 52. When the adhesive is discharged from the inside of the discharge hole 52, due to the continuous rotation of the shaft body 31 by the servo motor 33, the adhesive can come into contact with the mixed slurry and disperse, and the stirring effect is improved by the stirring blades 32;

[0074] During the downward movement of the moving plate 22, the convex block 23 will gradually contact the first baffle 41, causing the end of the first baffle 41 located inside the shaft body 31 to move downward. At this time, the end of the first baffle 41 away from the convex block 23 will drive the second baffle 44 to tilt, and due to the intermittent distribution of the convex blocks 23 and the cooperation of the arc-shaped spring 42, the first baffle 41 drives the second baffle 44 to perform intermittent up and down movements. When the bottom surface of the second baffle 44 fits with the top surface of the bottom plate 12, the second baffle 44 will scrape the top surface of the bottom plate 12 to prevent the slurry at the deepest layer from sticking;

[0075] Meanwhile, during the downward movement of the moving plate 22, it will drive the gear shaft 62 to rotate through the toothed plate 63. The end of the gear shaft 62 away from the toothed plate 63 will drive the J-shaped rod 61 to move outside the shaft body 31. At this time, the adjacent ends of the two J-shaped rods 61 will cross and move with each other to deflect the path of the adhesive discharged from the discharge hole 52, ensuring that the adhesive can be stirred by the two J-shaped rods 61 after being discharged, so that the adhesive can be evenly dispersed and mixed to the greatest extent.

[0076] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0077] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
