Description

Technical Field

[0002] Low-temperature SCR denitration catalyst is a catalyst used to reduce nitrogen oxide (NOx) emissions generated during combustion. SCR is the abbreviation of Selective Catalytic Reduction. Low-temperature SCR denitration catalyst can effectively convert NOx into harmless nitrogen and water vapor at a lower temperature (usually between 150°C and 400°C). This catalyst is usually a complex compound, and common components include oxides of elements such as vanadium, tungsten, and titanium, or salts of metals such as sodium and copper.

[0003] A low-temperature SCR denitration catalyst cutting device is usually used to cut and process waste catalysts in order to replace new catalysts. The existing cutting device usually includes a conveyor roller and a cutting knife. During cutting, the catalyst is conveyed to the cutting area by the conveyor roller, and the cutting knife cuts the catalyst. Since the catalyst is supported by the conveyor roller during cutting, it is easy to move, resulting in low cutting accuracy and even possible damage to the structure of the catalyst, affecting the use effect. Therefore, a low-temperature SCR denitration catalyst cutting device is designed to change the above technical defects. Utility Model Content

[0026] Here, the U-shaped connecting plate 6 can be lifted vertically by the operation of the first hydraulic cylinder 7. The lifting of the U-shaped connecting plate 6 enables the rectangular lifting box 3 to be lifted vertically inside the bottom support plate 1, thereby enabling the rectangular lifting box 3 to lift the denitration catalyst away from the surface of the longitudinal conveying roller 2, thereby preventing the denitration catalyst from being displaced on the surface of the longitudinal conveying roller 2.

[0028] Both ends of the second hydraulic cylinder 9 are fixed with transverse polished rods 13, which penetrate the interior of the circular sliding tube 12 and are slidably connected to the circular sliding tube 12, so that the circular sliding tube 12 can slide on the outside of the transverse polished rods 13, and then the circular sliding tube 12 can slide on the outside of the transverse polished rods 13, so that the moving trajectory of the circular sliding tube 12 can be guided by the transverse polished rods 13;
