Abstract

The utility model discloses a stainless steel trapezoid winding wire water cap, which is used on the water quality treatment devices of power stations, petrochemical industry, pharmacy factories, food factories and water works, etc. The utility model comprises a water cap upper cover 1, a water cap lower cover 2, a supporting pipe 7, ribs 9, a winding wire 6 and a winding wire filter screen cylinder 4 provided with a cavity 10. In the winding wire filter screen cylinder 4, a plurality of ribs 9 are arranged in round shape according to a certain interval and the outer side of the winding wire filter screen cylinder is wrapped by the winding wire 6. The two ends of the winding wire filter screen cylinder 4 are respectively connected with the upper cover 1 and the lower cover 2 by means of sealing, and the supporting pipe 7 and the lower cover 2 are connected. The utility model has the advantages of high compression strength, no crack and no maintenance and good back flushing effect, and water quality purity and flow cab be assured, etc.

Description

Stainless steel trapezoid wind wire water cap

The utility model relates to the trapezoidal wrapping wire water of a kind of stainless steel cap, is used for the treatment device for water of power station, petrochemical industry, pharmacy, food and waterworks etc., works to filter the water source.

Though existingly be used for the trapezoidal wrapping wire Long handed water cap of stainless steel on power station, petrochemical industry and the water treatment facilities to the original improvement of having made aspects such as structure with the water cap of plastics integral production, have the compressive strength height, can not rupture, need not advantages such as maintenance, but also have weak point.For example: owing to structural reason, it is not suitable for installing and is used for the tube sheet that certain requires required water treatment facilities, otherwise is difficult to guarantee the filtration result of the impurity such as deironing, desalination to the water source, to guarantee the pure of water quality.

Task of the present utility model be a kind of compressive strength height will be provided, can not rupture, not have maintenance, can be installed on certain tube sheet that requires required water treatment facilities, water treatment effect and the good trapezoidal wrapping wire water of the stainless steel cap of backwash effect.

Task of the present utility model is finished like this, the trapezoidal wrapping wire water of a kind of stainless steel cap, it comprises that water cap upper and lower cover 1,2, stay pipe 7, rib 9, wrapping wire 6 and one arrange conglobate its outside at a certain distance by some ribs 9 and holds the wrapping wire screen tube 4 with a cavity 10 that wrapping wire 6 forms, two ends of wrapping wire screen tube 4 are tightly connected with upper and lower cover 1,2 respectively, and stay pipe 7 is connected with lower cover 2.

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

Fig. 1 is the utility model structure chart.

Fig. 2 is the A-A cutaway view of the utility model Fig. 1.

Fig. 3 is the partial enlarged drawing of the utility model Fig. 1.

Fig. 4 is an example structure figure of the present utility model.

Fig. 5 is A '-A ' cutaway view of an example structure figure of the present utility model.

Being shaped as of wrapping wire 6 of the present utility model is trapezoidal, the utility model is got the some ribs 9 of length unanimity, some ribs 9 are arranged in cylindrical shape at a certain distance, connect wrapping wire 6 in its outside disc boxing again, thereby form a cavity 10, when the dish weldering, leave certain slit between the wrapping wire 6, from the slit so that current pass through.Because the shape of wrapping wire 6 is trapezoidal, so when being welded in wrapping wire 6 coilings on the rib 9, with the little head part and rib 9 solid weldings of wrapping wire 6, thereby make the shape in whole slit also be outer little interior big, to obtain good backwash effect.

The upper and lower end of wrapping wire screen tube 4 of the present utility model is tightly connected with water cap upper and lower cover 1,2 respectively, and water cap loam cake 1 has the sphere of a sealing, and the surface is difficult for dust-staying when its role is to change resin and sandstone.The hole that the central authorities of water cap lower cover 2 have a caliber with stay pipe 7 to match, an end edge and its solid welding with stay pipe 7 are processed with screw thread on the other end of stay pipe 7, are furnished with nut 8 on it, and the material that the utility model adopted is stainless steel.

When the utility model uses, as long as pass the hole of an end from the tube sheet 5 of water treatment facilities with stay pipe 7, and add rubber washer 3, the turn nut 8 then, make nut 8 collaborative rubber washers 3 tightly clamp tube sheet 5, the utility model is fixed on the tube sheet 5 thereby reach.Enter cavity 10 in the slit of water quality between wrapping wire 6 of flowing out, and flow out through the tube chamber of stay pipe 7 through filter course such as resin or sandstone.In whole water treatment procedure, when erosion thing in the cylindrical shell of water treatment facilities increases and when influencing flow, can carry out backwash, this moment, current then were pressed into cavity 10 by the tube chamber of stay pipe 7 as long as pressurize in tube sheet 5 bottoms in the cylindrical shell of water treatment facilities, in the slit between the wrapping wire 6, flow out then, because wrapping wire 6 is trapezoidal,, the erosion thing and drain into the outside thereby be convenient to the current band so the slit is interior big outer little, to improve backwash effect, guarantee the normal supply of interior cleaning of cylindrical shell and current.

Even change a little, be about to the fixture 11 that nut 8 is transformed into Ω shape as shown in Figure 4, fixture 11 is enclosed within on the support bar 7-1, and then adds nut 8-1, the trapezoidal wrapping wire water of whole stainless steel cap is fixed on the tube sheet 5 in the cylindrical shell of water treatment facilities to reach in the outer end of fixture 11.But such scheme does not exceed scope of the present utility model yet.

The utility model because after having done above-mentioned improvement, improved the compressive strength height, can not rupture, not have maintenance, backwash effect is good, can guarantee the advantages such as water quality purity and flow.
