Device for assembling the sprinkler block of a cooling tower from polyvinyl chloride corrugated sheets

摘要

The utility model relates to the field of recycled water supply, namely to the structural elements of cooling towers and other apparatus for heat and mass transfer between liquid and gaseous media. A device for assembling a block of irrigators of cooling towers from polyvinyl chloride corrugated sheets contains heaters in the form of rods with an end contact surface for welding corrugated sheets made with alternating protrusions and depressions and mounted on each other so that the depressions above the corrugated sheet are located on the protrusions downstream corrugated sheet, the device is made in the form of a vertical frame with a horizontally movable table m for sequential installation of welded corrugated sheets on it and a welding panel located above it, fixed on the rod mounted on the frame of the pneumatic system for reciprocating movement in the vertical direction of the welding panel relative to the corrugated sheets installed on the movable table, while the heaters in the form of rods are made with teflon coating and mounted on the welding panel above the place of coincidence of the protrusions and depressions of the corrugated sheets, the number of heaters in the idea of the rods coincides with the number of depressions of the corrugated sheet below them, coinciding with the protrusions of the lower corrugated sheet, the welding panel is equipped with guide rods mounted on the side of its opposite edges, passed through the guide bushings fixed on the vertical frame, and the heaters in the form of rods are made with the possibility of heating the central the area of contact of the protrusions of the lower corrugated sheet and depressions above the corrugated sheet to a temperature 120 ° С to ensure the diffusion-rheological process of the interaction of the welded surfaces of the protrusions and depressions of adjacent corrugated sheets, the movable table and the welding panel being installed with the possibility, during the assembly of the sprinkler block, to lay new corrugated sheets on top of the corrugated sheets welded together to achieve the desired sprinkler block size . The result is an increase in the reliability of the sprinkler block by increasing the rigidity of the sprinkler block design.
