Description

Honeycomb denitration catalyst monomer upset pairing loading attachment Technical Field The invention relates to the technical field of flue gas denitration environment-friendly equipment, in particular to a honeycomb denitration catalyst monomer overturning pairing feeding device. Background The Selective Catalytic Reduction (SCR) technology is a main stream core technology for treating nitrogen oxides in fixed source flue gas of thermal power, steel, coking, cement and the like in China at present, and the honeycomb denitration catalyst is a core functional consumable of an SCR denitration system by virtue of the advantages of large specific surface area, high catalytic activity, strong flue gas adaptability, stable running resistance and the like. In engineering application and industrial production, honeycomb denitration catalyst monomers are required to be assembled into a reactor mounting frame according to preset interval arrangement, and sealing spacers are required to be arranged between adjacent catalyst monomers so as to prevent short circuit of flue gas and ensure denitration efficiency. A two-stage drying box for honeycomb SCR denitration catalyst disclosed in patent publication No. CN204535288U, wherein the drying trolley is provided with a plurality of layers of products, and product spacers are arranged between two adjacent products and between the products and the drying trolley. The assembly precision and the pasting stability of the sealing spacer directly determine the denitration performance and the long-term operation reliability of the SCR system. At present, the assembly and the feeding assembly of the cellular denitration catalyst monomer in the industry generally adopt a manual assembly process, namely, firstly, the catalyst monomer is horizontally placed, glue is brushed and stuck on the edges of the two sides of the top of the monomer block by manual operation, short strip-shaped sealing spacers are stuck, then, the monomer is integrally turned over by manual operation for 90 degrees, the spacers which are originally stuck on the top are rotated to the sides of the monomer, then, the monomer is manually moved into the mounting frame block by block, the spacers of the adjacent monomers are mutually attached, after the assembly of one layer of monomers is completed, the long strip-shaped spacers are paved on the top of the upper layer of the monomer group, and the multi-layer assembly is completed by repeating the procedures. The prior art has the following technical defects which cannot be overcome: first, the manual dependency is high, and assembly efficiency is extremely low, can't adapt to large-scale continuous production. The existing technology relies on manual work to complete the whole processes of glue brushing, pad pasting, overturning, assembly and frame entering, the assembly of single-group monomers is long in time consumption, the manual labor intensity is high, the productivity bottleneck is outstanding, and a continuous automatic production line cannot be formed with the front and rear procedures of catalyst calcination, cutting, hole cleaning and the like. Secondly, the assembly consistency of the spacer is poor, and the sealing reliability is insufficient. The short spacer is pasted block by block manually, the glue quantity control and the pasting position completely depend on the experience of operators, the problems of glue overflow, missing coating, spacer deflection, high-low dislocation and the like are very easy to occur, the single unit is not tightly attached to the rear sealing surface, the flue gas short circuit occurs in the operation of the SCR system, the denitration efficiency is directly reduced, and the increasingly strict environment-friendly emission requirement cannot be met. Thirdly, the spacer is easy to rub and fall off, and the yield is low. In the processes of moving and assembling after the single bodies are turned over, the spacer adhered to the side surface is extremely easy to contact and rub with the supporting surface and the adjacent single bodies, so that the spacer is curled, rubbed and falls off, sealing failure is finally caused, and the production cost is greatly increased. Disclosure of Invention Based on the above, it is necessary to provide a honeycomb denitration catalyst monomer overturning pairing feeding device aiming at the technical problems. In order to achieve the above purpose, the invention adopts the following technical scheme: the honeycomb denitration catalyst monomer overturning pairing feeding device comprises a material table, a gantry truss manipulator, a monomer arrangement mechanism and a lifting mechanism, wherein the gantry truss manipulator is arranged above the material table and can move along the X-axis, Y-axis and Z-axis directions; The monomer arrangement mechanism comprises: An equidistant traversing mechanism connected with the output end of the gantry truss manipulator and driven to move by the
