2The achievement that control obtains is for reducing acid rain intensity and frequency aspect DeGrain.China is just wideling popularize denitration technology at present, and SCR (SCR) technology is the major technique of coal-fired flue gas denitration, and catalyst is one of key technology in the SCR technology.The integral catalyzer type of engineering application at present mainly contains three kinds: board-like, cellular and corrugated plate dst, wherein, board-like catalyst is big with its aperture area, help flying dust passes through, and adopt metal sieve plate as carrier, mechanical strength is good, the coal-fired high grey SCR denitration occasion of particularly suitable and obtain using comparatively widely.Can be in present stage, board-like catalyst mainly is to adopt artificial preparation, will be equipped with good catalyst pulp by hand and be coated with the base material of scraping at certain specification (on steel plate or the steel wire), labor strength, inefficiency, the production cost height, and catalyst quality is difficult to be guaranteed.
The utility model content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provide a kind of rational in infrastructure, effectively increase work efficiency and the board-like Preparation of catalysts device of denitration of product quality.
The technical scheme that its technical problem that solves the utility model adopts is: comprise frame, motor, emptying roller, slurry bucket, scrape hopper, scraper, pressure roller, cutting knife and chopping block; Side in frame is equipped with the emptying roller of dispensing as the expanded metal lath of base material, be equipped with on the rear portion frame of emptying roller and scrape hopper, scrape the hopper top slurry bucket is housed, catalyst pulp is spread on the base material, slurry tank the upper back be provided with scraper, catalyst pulp is wipeed off equably; The receiving hopper of slurry tank lower end links to each other by elevator with slurry bucket, and the unnecessary catalyst pulp that scrapes is carried the overfall hopper; Be provided with in the slurry tank rear end by motor-driven, be the upper and lower pressure roller that distributes up and down, on the one hand the base material clamping is carried, on the other hand base material and slurry are rolled into one, the formation triple laminate.Be provided with chopping block on the frame of the rear portion of upper and lower pressure roller, the top of chopping block is provided with cutting knife, rolling good triple laminate is cut into the block blank of required size.
Effectively rolling for the transmission that guarantees base material and base material and slurry is provided with drive above last pressure roller, drive and on pressure roller continuous by driving belt; The both sides of lower compression roller and below also be provided with drive, drive and lower compression roller are linked to each other by driving belt.Like this, the drive of lower compression roller both sides and belt play the support effect to base material and slurry, prevent that the base material that has slurry is out of shape because of load-bearing.During use, scribble glycerine at belt and slurry contact-making surface, preventing that slurry from adhering to belt in the operation of rolling and peeling off with base material influences catalyst and makes quality.And being provided with of belt also shields to upper and lower pressure roller, avoids being stuck because of the weathering in air of catalyst viscous paste, drying cause in the upper and lower pressure roller operation process, influences the normal operation of preparation facilities.
Be transported to subsequent processing for ease of the block blank after the cutting, be provided with conveyer belt at the rear portion of chopping block.
The beneficial effects of the utility model are: rational in infrastructure, be easy to make, reduced labor strength and production cost effectively, and improve production efficiency, and guaranteed the product quality of board-like catalyst.
