Description

Technical Field

[0001] The invention belongs to the technical field of filter material preparation, and in particular is a method for preparing a water poisoning-resistant, dust-removal and denitrification integrated filter material. Background Art

[0002] The water-resistant poisoning dust removal and denitrification integrated filter material is a high-performance air filter material that is designed to achieve the functions of dust removal and denitrification at the same time, and has the characteristics of water resistance and anti-poisoning. It is a technical product that integrates dust removal and denitrification catalytic functions. The denitrification catalyst is loaded on the dust removal filter material in the form of a finished product or a precursor, so as to carry out the coordinated management of dust removal and denitrification. This filter material can not only effectively filter particulate matter in the air, but also catalytically decompose nitrogen oxides to achieve the dual effects of dust removal and denitrification. At the same time, it is also resistant to water and poisoning, and can maintain stable filtering performance in a humid environment or an environment containing harmful substances.

[0003] In the existing process of preparing water-resistant poisoning dust removal and denitrification integrated filter materials, when preparing catalytic filter membranes, it is necessary to mix and stir the prepared mixed slurry with a certain amount of binder. However, since the mixed slurry has a certain viscosity, and the binder that mixes well with the slurry, such as polyvinyl butyral, is generally in the form of loose powder, which is poured from above and covered on the top surface of the mixed slurry, and combined with the existing single stirring method, the two are mixed. This method of pouring the binder from top to bottom easily causes the deeper areas of the mixed slurry to be unable to be fully mixed with the binder, which in turn causes the mixing degree to deteriorate, so it needs to be improved.

[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] With the above solution, the servo motor 33 is running, driving the shaft 31 to rotate in the inner cavity of the shell 11 , and synchronously causes the stirring blades 32 to rotate in the same direction in the inner cavity of the shell 11 .

[0059] like Figure 7 and Figure 8 As shown, the output shaft of the servo motor 33 is in an I-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] The above scheme is adopted: when the cover plate 13 is gradually moved upward to the shell 11 by using the electric telescopic cylinder 7, the output shaft of the servo motor 33 will be out of contact with the notch of the shaft body 31. When the shaft body 31 needs to be rotated, the electric telescopic cylinder 7 drives the servo motor 33 downward, and the output shaft of the servo motor 33 will be tightly stuck in the notch of the shaft body 31. As a result, when the servo motor 33 is running, the "I"-shaped design of its output end can smoothly drive the shaft body 31 to rotate.

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

[0062] The upper end of the moving plate 22 is in the shape of a truncated cone with a "wide upper part and narrow lower part", and is in contact with the push rod 55. When the moving plate 22 moves downward.

[0063] With the above solution, due to the fixing effect of the material storage tube 51 and the shaft body 31 , the truncated cone-shaped upper end of the material storage tube 51 will gradually come into contact with the push rod 55 , so that the push rod 55 is forced to gradually move toward the inside of the material storage tube 51 .

[0064] like Figure 4 , Figure 5 and Figure 8 As shown, the movable module 4 includes a first baffle 41, two ends of which are respectively located on the inner and outer sides of the shaft body 31, the first baffle 41 located in the inner cavity of the shaft body 31 is rotatably connected to the inner cavity of the shaft body 31, and one end of the first baffle 41 located outside the inner cavity of the shaft body 31 is hinged with a second baffle 44, and one end of the second baffle 44 away from the first baffle 41 is hinged to the top surface of the bottom plate 12.

[0065] like Figure 4 and Figure 8 As shown, the first baffle 41 is located in the inner cavity of the shaft body 31 and an arc spring 42 is installed at one end. The top of the arc spring 42 is fixedly connected to the inner cavity of the shaft body 31. The upper and lower sides of the middle part of the first baffle 41 and the connection area of ​​the shaft body 31 are connected with folding rubber baffles 43. The end of the first baffle 41 away from the second baffle 44 abuts against the protrusion 23.

[0066] The above scheme is adopted: when the moving plate 22 drives the protrusion 23 downward, the end of the protrusion 23 will contact the first baffle plate 41 to make the first baffle plate 41 flip and rotate. At this time, the first baffle plate 41 will make the second baffle plate 44 close to the end of the first baffle plate 41 tilt upward, that is, the second baffle plate 44 is tilted from a horizontal state. At this time, the upper and lower folding rubber baffles 43 in the connection area between the middle end of the first baffle plate 41 and the shaft body 31 will change synchronously, that is, the folding rubber baffle plate 43 located at the top is compressed, and the folding rubber baffle plate 43 located at the bottom is stretched. The design of the folding rubber baffle plate 43 prevents the slurry inside the shaft body 31 from penetrating into the interior of the shaft body 31 through the connection area between the first baffle plate 41 and the shaft body 31 during the operation of the device, thereby playing a protective role.

[0067] like Figure 6 , Figure 8 and Fig. 9 As shown, the upper and lower sides of the material storage tube 51 away from the push rod 55 are provided with discharge holes 52, and the push rod 55 is elastically connected to the material storage tube 51 through a first spring 56;

[0068] A block is installed at one end of the push rod 55 located outside the material storage tube 51 to prevent the push rod 55 from continuously entering the material storage tube 51 .

[0069] like Figure 8 and Fig.10 As shown, the toggle assembly 6 includes a tooth plate 63, which is fixed to the upper and lower ends of the side wall of the shift plate 22, and one side of the tooth plate 63 is meshedly connected with a gear shaft 62, and one end of the gear shaft 62 away from the shift plate 22 passes through the shaft body 31 and extends to the outer end of the shaft body 31 and is fixed to a J-shaped rod 61, and one end of the gear shaft 62 located inside the shaft body 31 is rotatably connected to the shaft body 31;

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

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

[0072] First, the cover plate 13 is raised by the electric telescopic cylinder 7 to increase the gap between the cover plate 13 and the housing 11, and the operator is instructed to pour the mixed slurry into the housing 11. The electric telescopic cylinder 7 is then started again to pass through the cover plate 13 to move the servo motor 33 downward, and the output shaft of the servo motor 33 is stuck in the notch on the top surface of the shaft body 31. A certain amount of adhesive is divided into two parts and poured into the two discharge pipes 54 respectively, and enters the discharge trough 53 through the discharge pipes 54. Then, the adhesive is filled in the area of ​​the inner cavity of the storage pipe 51 near the discharge hole 52 through the opening of the discharge trough 53.

[0073] Afterwards, the pneumatic cylinder 21 is started so that the pneumatic cylinder 21 drives the moving plate 22 downward. During the downward movement of the moving plate 22, the outer wall of the upper end of the frustum-shaped plate first contacts the push rod 55, so that the push rod 55 gradually moves inside the storage tube 51 and pushes the adhesive inside the storage tube 51 to be discharged from the discharge hole 52 to the inside of the shaft body 31. When the adhesive is discharged from the inside of the discharge hole 52 to the outside, the shaft body 31 is continuously rotated by the servo motor 33, so that the adhesive can contact with the mixed slurry and be dispersed, and the stirring effect is improved by the stirring blades 32.

[0074] During the downward movement of the moving plate 22, the protrusion 23 will gradually contact the first baffle 41, so that the end of the first baffle 41 located inside the shaft body 31 moves downward. At this time, the end of the first baffle 41 away from the protrusion 23 will drive the second baffle 44 to tilt, and through the intermittent distribution of the protrusion 23 and the cooperation of the arc spring 42, the first baffle 41 drives the second baffle 44 to move up and down intermittently. When the bottom surface of the second baffle 44 fits 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] At the same time, when the shift plate 22 is moving downward, it will drive the gear shaft 62 to rotate through the tooth plate 63, and the end of the gear shaft 62 away from the tooth plate 63 will drive the J-shaped rod 61 to move on the outside of the shaft body 31. At this time, the adjacent ends of the two J-shaped rods 61 will cross each other and move 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 dispersed and mixed evenly to the greatest extent.

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