Abstract

The utility model relates to a cross water intake apparatus with trapezoid stainless steel winding wires, comprising a five-way pipe unit 2 and flanges 1 welded and fixed on the five orifices of the five-way pipe unit 2. Four trapezoid stainless steel winding wire filter elements 3 are respectively abutted with the flanges 1 on the four cross orifices of the five-way pipe unit 2. The utility model has the advantages of convenient replacement, and when an ion exchanger performs the procedure of backwashing, not only the ion exchange resin does not run away, but also the utility model can ensure the contaminants to be carried outside the exchanger, and meanwhile, when the ion exchanger normally operates, the utility model can also improve the uniformity of water distribution, having more favorable action of protecting the evenness and stability of the ion exchange resin bed.

Description

The trapezoidal wrapping wire water feed apparatus of cross stainless steel

The utility model relates to the trapezoidal wrapping wire water feed apparatus of a kind of cross stainless steel, is the improvement that the existing cross that is used for the water quality pre-processing device-ion-exchanger of power station, petrochemical industry and waterworks etc. is propped up the cast water feed apparatus.

At present, the cross in the ion-exchanger props up the cast water feed apparatus, generally is to offer the uniform aperture of intersection with 45 °～60 ° angles below its arm.The water feed apparatus of this structure, on the one hand, when implementing the computer program control operation, usually when carrying out " backwash " programmed instruction, the ion exchange resin of running away at the water feed apparatus place; On the other hand, because operation workman operate miss, when backwash, the resin of also can running away at the water feed apparatus place like this, had both been wasted expensive ion exchange resin, had brought unsafe factor to system again.

The purpose of this utility model is to provide a kind of replacing convenient, and ion-exchanger is when " backwash " program of execution, and the ion exchange resin of neither can running away can guarantee again to take dirt out of interchanger external; Exerting oneself in the time of simultaneously, can also guaranteeing ion-exchanger normally moved can the trapezoidal wrapping wire water feed apparatus of influential cross stainless steel.

The purpose of this utility model is achieved like this, the trapezoidal wrapping wire water feed apparatus of a kind of cross stainless steel, it comprises that five-way pipe fitting 2 and solid welding dock with flange 1 on four cross mouths of pipe of five-way pipe fitting 2 respectively at the flange 7 of the trapezoidal wrapping wire filter element 3 of 1, four stainless steel of flange on five mouths of pipe of five-way pipe fitting 2 by the solid welding of one end.

Below in conjunction with accompanying drawing the utility model is done further narration.

Fig. 1 is a stereogram of the present utility model.

Fig. 2 is the structure diagram of the trapezoidal wrapping wire filter element 3 of stainless steel of the present utility model.

Gap width 4 between the wrapping wire 5 on the trapezoidal wrapping wire filter element 3 of stainless steel of the present utility model is ion exchange resin effective grain size d ₁₀± 0.05mm.Ion exchange resin effective grain size d wherein ₁₀Be meant that 90% ion-exchange resin particles is retained in the screen-aperture on the sieve, generally at 0.3～1.0mm.Total program of flow area for governing of the trapezoidal wrapping wire filter element 3 of stainless steel is 3～6 times of water inlet manifold sectional area.The trapezoidal wrapping wire filter element 3 of stainless steel of the present utility model is that the rib 6 by some length unanimities is arranged in cylindrical shape by certain spacing, the wrapping wire 5 that connects stainless steel in its outside disc boxing combines again, when the dish weldering, leave certain interval between the wrapping wire 5, from the slit so that current pass through.The shape of wrapping wire 5 is trapezoidal, when being welded in wrapping wire 5 coilings on the rib 6, with the trapezoidal little head part and rib 6 solid weldings of wrapping wire 5, it is outer little interior big that thereby the shape that makes whole slit is, this structure when ion-exchanger is carried out " backwash " program, helps dirt is taken out of external; Simultaneously, because the gap width 4 between the wrapping wire 5 is designed to ion exchange resin effective grain size d ₁₀± 0.05mm (wherein gap width 4 is meant the interval width of trapezoidal wrapping wire 5 enlarged head offices), thereby when backwash, can prevent from effectively the loss of expensive ion-exchange resin particles to have guaranteed the security of whole system; Once more, because total program of flow area for governing of the trapezoidal wrapping wire filter element 3 of stainless steel is 3～6 times of the water inlet manifold sectional area, therefore can not produce any influence to exerting oneself of the normal operation of ion-exchanger.

The utility model is when assembling, elder generation is at the end difference solid welding upper flange 7 of four trapezoidal wrapping wire filter elements 3 of stainless steel, five mouths of pipe difference solid welding flanges 1 at five-way pipe fitting 2, and then the flange 7 of four trapezoidal wrapping wire filter elements 3 of stainless steel docked with flange 1 on four cross mouths of pipe of five-way pipe fitting 2 respectively, and by screw both are fixed up, constitute a complete water feed apparatus.Flange 1 on another of five-way pipe fitting 2 mouth of pipe vertical with four cross mouths of pipe connects with the water inlet pipe of ion-exchanger when mounted.When the utility model carries out the retrofit work of water feed apparatus at ion-exchanger, only need the water inlet pipe of original ion-exchanger and the connecting flange between the distributing pipe are unloaded, install this water feed apparatus again and get final product.

Water feed apparatus of the present utility model is because after adopting the trapezoidal wrapping wire filter element 3 of stainless steel, the expensive ion exchange resin of not running away when both having satisfied " backwash " can guarantee dirt is taken out of external again; Simultaneously, when ion-exchanger normally moves, also can greatly improve the uniformity of water distribution of water inlet, can play better effect the smooth stability of protecting the ion exchange resin bed layer.
