[0002] Honeycomb denitration catalysts are a type of highly efficient environmental protection material, mainly used to reduce nitrogen oxide emissions in industrial waste gases. This catalyst gets its name from its unique honeycomb structure. Its basic composition includes titanium dioxide as the main carrier, vanadium pentoxide as the main active ingredient, and other metal oxides such as tungsten trioxide as auxiliary ingredients. During the production process, these components are mixed and made into honeycomb-shaped elements with a honeycomb cross-section through a ceramic extrusion device, and then assembled into standard modules.

[0003] After the raw materials for honeycomb denitration catalyst production are kneaded, the materials need to be filtered to remove impurities in the materials to prevent clogging of the mold during molding and affecting the formation of the catalyst. However, the existing filtering equipment has a relatively single filtering process during use, which easily leads to incomplete filtering and material waste.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the utility model.

[0029] In the description of the present utility model, it should be understood that the terms "open hole", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the utility model.

[0030] Please refer to Figure 3 , Figure 5 As shown in the figure, the present utility model is a filtering device for manufacturing honeycomb denitration catalyst, including an operating table 1. A filtering device 2 is arranged inside the operating table 1. A sealing plate 3 is fixedly connected to the top of the filtering device 2. A stirring device 4 is arranged on the top of the sealing plate 3. The output end of the stirring device 4 extends into the filtering device 2. The inner walls of the filtering device 2 are respectively fixedly connected with a first filter plate 5 and a second filter plate 6.

A stirring and swirling assembly 10 is arranged on the top of the second filtering device 8.

[0031] When it is necessary to filter the material after mixing the honeycomb denitration catalyst, it is introduced into the interior of the filtering device 2 through the input channel at the top of the sealing plate 3. At the same time, the stirring device 4 is started to operate inside the filtering device 2, and stirring components are arranged at the top positions of the first filtering plate 5 and the second filtering plate 6 outside the stirring device 4. In this way, when the material falls onto the first filtering plate 5, the stirring device 4 is used to stir it to accelerate the fluidity of the material, and the impurities are blocked above by the sieve holes on the first filtering plate 5. When the filtered material falls onto the second filtering plate 6, the stirring device 4 continues to stir and filter it. The impurities blocked on the first filtering plate 5 and the second filtering plate 6 are continuously stirred and pushed into the output pipe 7 by the stirring device 4 and gradually flow into the interior of the second filtering device 8, and are rotated and stirred by the rotating and stirring component 10 to separate the filtered impurities again. The separated material enters the conveying device 9 through the bottoms of the filtering device 2 and the second filtering device 8 for output.

[0032] In the present utility model, the stirring device 4 is fixed on the top of the sealing plate 3, and its stirring end extends into the interior of the filtering device 2. After the material after mixing is completed and enters the interior of the filtering device 2, through the continuous stirring of the stirring device 4, the material can be multi-stage filtered in cooperation with the first filtering plate 5 and the second filtering plate 6. At the same time, the filtered impurities can enter the interior of the second filtering device 8 again. The rotating and stirring component 10 can rotate and stir the separated impurities inside it, so that a small amount of material contained in the impurities is filtered and separated again, so as to achieve the effect of full filtration and reduce the waste of materials during the filtering operation.

[0034] The bottom outlet of the flow collecting hopper at the bottom of the filtering tank 201 gradually narrows. When the material is separated by secondary filtration, it gradually flows into the interior of the flow collecting hopper, and the filtered material can be more concentratedly output to the conveying device 9 in cooperation with the closed pipe.

[0035] In one embodiment, for the above-mentioned stirring device 4, the stirring device 4 includes a stirring motor 401, an output shaft 402 is fixedly connected to the output end of the stirring motor 401, a swirl plate 403 is threadedly connected to the outer surface of the output shaft 402, the number of the swirl plates 403 is two groups, and the two groups of swirl plates 403 are respectively located at the tops of the first filtering plate 5 and the second filtering plate 6.

[0036] The stirring motor 401 is fixed to the top of the sealing plate 3. After starting the stirring motor 401, its driving output shaft 402 drives the swirling plate 403 to rotate, so that the two groups of swirling plates 403 rotate and stir above the first filter plate 5 and the second filter plate 6 respectively at the same time, providing a driving force for the filtration and separation of the material.

[0037] By arranging the swirling plates 403 at different height positions of the output shaft 402 respectively and swirling and stirring on the first filter plate 5 and the second filter plate 6, the fluidity of the material is increased, so that the material cooperates with the sieve holes of different fineness on the first filter plate 5 and the second filter plate 6 to block the impurities above, so as to achieve the effect of fully filtering and separating the material after mixing.

[0038] In one embodiment, for the above-mentioned swirling plate 403, the swirling plate 403 is cross-distributed on the outer surface of the output shaft 402, and a rotating scraping plate 404 is fixedly connected to the outer surface of the output shaft 402, and the rotating scraping plate 404 is trapezoidal in reverse.

[0039] By arranging the rotating scraping plate 404 at the bottom end of the output shaft 402 and fitting it to the inner wall of the flow collecting hopper, when the filtered material enters the inside of the flow collecting hopper, the continuous rotation of the rotating scraping plate 404 can accelerate the flow rate of the material inside the flow collecting hopper, and at the same time make the material on its inner wall break away and flow downward, so that the material can be discharged in time.

[0043] After the stirring motor 1011 is started, it drives the stirring shaft 1012 to drive the stirring plate 1013 to rotate. After the filtered material flows through the output pipe 7 into the second filter tank 801, it is stirred on the bottom filter plate 802 inside the second filter tank 801 in cooperation with the stirring plate 1013, so as to provide a filtering driving force for the small amount of mixed material in the impurities, enabling the small amount of material in the impurities to be separated quickly again to avoid waste of materials.

[0045] By arranging the conveying cylinder 901 inside the operation table 1, when the materials in the filter tank 201 and the second filter tank 801 are both filtered, they gradually flow into the conveying cylinder 901, and the conveying motor 902 drives the spiral shaft 903 to rotate to continuously output the materials.

[0046] In one embodiment, for the above-mentioned sealing plate 3, a fixing plate 11 is fixedly connected to the top of the sealing plate 3, and a bolt 12 is threadedly connected to the top of the fixing plate 11.
