Abstract
The utility model relates to the technical fields of power stations, petroleum, chemical industry, tap water equipment and the like. The strainer comprises an upper cover plate, a lower cover plate, a filter element and a central steel pipe, wherein the inner side of the upper cover plate is welded with the central steel pipe; the upper end of the central steel pipe is provided with a radial slot; the lower end of the central steel pipe penetrates and is arranged on the lower cover plate; the central steel pipe is fixedly connected with the lower cover plate; the lower end of the central steel pipe is provided with a thread; the filter element is arranged between the upper cover plate and the lower cover plate and comprises a wire wrap and 8-12 reinforcing ribs; the cross section of the wire wrap is trapezoidal; after the wire wrap is spirally wound on the reinforcing ribs at a consistent gap, the wire wrap is welded and fixed; and 8-12 reinforcing ribs are evenly distributed along the circumference direction on the inner side of the filter element. According to the design, the strainer disclosed by the utility model has the advantages of reasonable structure, high pressed strength and small possibility of cracking, so that the maintenance cost is lowered, and the service life of the strainer is prolonged. In addition, the strainer has a big circulation area and small possibility of blocking, no catalyst runs off, and the equipment processing efficiency is improved.
Description
Technical field
The utility model relates to technical fields such as power station, oil, chemical industry and water works, especially as the important tower internals of equipment such as the tower of large-scale petrochemical equipment, reactor.
Background technology
The key effect of water cap is: one, increase the circulation area of material on tower tray; Two, stop catalyst granules to be taken out of outside the container; Three, reduce the bed pressure drop of tower or reactor.
The water cap is installed on tower or the interior tray deck of reactor, a certain amount of catalyst of packing in tower or reactor.When feeding material in tower or the reactor, material is with after catalyst fully contacts, and reacted product flows out from the filter element gap, carries out mass exchange, owing to catalyst is fine granularity, will guarantee that in mass exchange catalyst is not taken out of outside the container.Little, the easy obstruction of existing water cap ubiquity circulation area, low, the wire easy fracture of compressive strength, defectives such as maintenance cost height.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide not easy fracture of big, the difficult obstruction of a kind of circulation area, compressive strength height, wire, the water cap that maintenance cost is low.
The purpose of utility model is achieved in that the water cap, comprise upper cover plate, lower cover, filter element and center steel pipe, welding center, the inboard steel pipe of upper cover plate, the upper end of center steel pipe is provided with radial slot, the lower end of center steel pipe is placed through on the lower cover, the center steel pipe is fixedlyed connected with lower cover, and the lower end of center steel pipe is provided with screw thread; Between described upper cover plate and the lower cover filter element is set, filter element is made up of wrapping wire and 8 to 12 reinforcements, the cross section of wrapping wire is trapezoidal, and wrapping wire spacer ring back welding on reinforcement of also formation unanimity of shape is in the shape of a spiral fixed, and 8 to 12 reinforcements are uniform along filter element inside circumference direction.
The utility model is by above design, and is rational in infrastructure, compressive strength is high, easy fracture not, thereby reduced maintenance cost, prolonged the service life of water cap, and water cap circulation area is big, difficult to be stopped up, and the catalyst-free loss, has improved the treatment effeciency of equipment.
