Background

With the development of water treatment technology, various novel water treatment technologies are developed, wherein the membrane technology is rapidly popularized and applied in various industrial fields by virtue of the advantages of energy conservation, simplicity and convenience in operation, high treatment efficiency and the like. As the most efficient and common membrane element form, the roll-type membrane element is composed of a water collecting pipe, a separation membrane wound on the water collecting pipe, a concentrated water diversion net, a fresh water diversion net and end covers at two ends of the water collecting pipe.

There are following problems among the prior art, current end cover is the big flux opening that many strengthening ribs formed, can lead to the too big a series of problems that lead to the fact of flow when using, influence the equipment operation, some end covers set up the apron on adjacent strengthening rib and then beat the hole control flow on the apron, the hole size of this kind of structure is unanimous, because the little relative filtration capacity of the membrane winding area that is close to the center tube is just little, and under the condition of the same hole, the membrane that is close to the center tube will bear great flow, make the hole block up just easily.

SUMMERY OF THE UTILITY MODEL

For this reason, it is desirable to provide an end cap that is provided with progressively larger through holes so that the flow rate of each through hole matches the filtration of the membrane, preventing clogging of the through holes, and reducing loss of the membrane.

In order to achieve the above object, the utility model provides an end cover, including solid fixed ring, gu fixed ring's inner ring integrated into one piece has a barrier plate, barrier plate puts at solid fixed ring's central point and has seted up the connecting hole, be equipped with a plurality of strengthening rib between connecting hole and the solid fixed ring, barrier plate has the through-hole along self thickness running through, the through-hole is along the connecting hole towards solid fixed ring's direction aperture grow gradually. Through the through-hole of grow gradually, the through-hole that is close to the connecting hole is less, and the through-hole that is close to solid fixed ring is great to make the flow of every through-hole and the filtration phase-match of membrane, prevent the through-hole jam, and reduce the loss of membrane.

Further, the reinforcing ribs are arranged at equal intervals along the circumference of the fixing ring. The water flow can be uniformly distributed between two adjacent reinforcing ribs, so that the water receiving area on the blocking plate is equal.

Furthermore, the reinforcing rib is a linear reinforcing rib which is extended from the fixing ring to the direction of the connecting hole and is not connected with the connecting hole. Can distribute water at equal intervals.

Furthermore, the reinforcing rib is an oblique line reinforcing rib, the connecting hole extends upwards along the axial direction of the through hole to form a connecting ring, and the linear type reinforcing rib extends from the fixing ring towards the connecting hole and is tangent to the connecting ring.

Further, the oblique line reinforcing rib starts to be radially twisted from the fixing ring toward the direction of the connecting hole. When water flow impacts on the reinforcing ribs, the water flow can rotate and flow along the twisted surface to form a vortex.

Furthermore, the outer wall of the fixing ring is inwards sunken to form a sealing groove. Plays a certain role in sealing.

Furthermore, the fixed ring is provided with a skirt edge in a surrounding way, and the outer wall of the skirt edge is provided with anti-skid lines. Better attachment to the membrane.

Different from the prior art, the technical scheme has the following beneficial effects:

1. the utility model discloses a through-hole that is equipped with grow gradually, the through-hole that is close to the connecting hole is less, and the through-hole that is close to solid fixed ring is great to make the flow of every through-hole and the filtration phase-match of membrane, prevent that the through-hole from blockking up.

2. The utility model discloses be equipped with the slash strengthening rib, when rivers strike on the strengthening rib, can make rivers form the swirl along turning round the rotatory flow of curved surface.

Example 1:

referring to fig. 1, the end cap of the present embodiment includes a fixing ring 1, a blocking plate 2 is integrally formed on an inner ring of the fixing ring 1, the blocking plate 2 is provided with a connecting hole at a center of the fixing ring 1, the blocking plate 2 is circular, a central axis of the circular blocking plate 2 coincides with a central axis of the fixing ring 1, a plurality of reinforcing ribs 3 are provided between the connecting hole and the fixing ring 1, the reinforcing ribs 3 are perpendicular to the blocking plate 2, the blocking plate 2 is provided with a through hole 4 penetrating through the blocking plate 2 along its thickness, and the aperture of the through hole 4 gradually increases along the connecting hole toward the fixing ring 1. Through gradually becoming bigger through-hole 4, the through-hole 4 that is close to the connecting hole is less, and the through-hole 4 that is close to solid fixed ring 1 is great to make the flow of every through-hole 4 and the filtration phase-match of membrane, prevent that through-hole 4 from blockking up, and reduce the loss of membrane.

In this embodiment, the specific number of the reinforcing ribs 3 is six, and the six reinforcing ribs 3 are arranged at equal intervals along the circumference of the fixing ring 1. So that the water flow can be uniformly distributed between two adjacent reinforcing ribs 3, and the water receiving areas on the blocking plates 2 are equal. Specifically, the reinforcing rib 3 is a linear reinforcing rib 3, the linear reinforcing rib 3 is formed by extending the inner ring of the fixing ring 1 towards the connecting hole, and is not connected with the connecting hole, so that water can be distributed at equal intervals, and the through holes 4 are formed between two adjacent reinforcing ribs 3.

In this embodiment, the outer wall of the fixing ring 1 is inwards recessed with a sealing groove 6, and a sealing ring is installed in the sealing groove 6 to play a certain sealing role.

In this embodiment, fixed ring 1 girth is encircleed and is equipped with a shirt rim 7, the outer wall of shirt rim 7 is equipped with anti-skidding line, when the installation has twined the center tube of membrane, can make the interior laminating of shirt rim 7 in the outside of membrane, better be connected with the membrane.

When specifically using, establish earlier on being used for filterable book formula membrane through establishing shirt rim 7 cover, then the center tube and the connecting hole fixed connection of book formula membrane, then overlap the sealing washer on solid fixed ring 1's seal groove 6, thereby the installation is accomplished, then liquid will follow one section inflow, then liquid is separated by strengthening rib 3 and flows to barrier plate 2 respectively, then pass through the book formula membrane on the through-hole 4 flow direction center tube of liquid, thereby it is just also less just to be close to the less flow in through-hole 4 aperture of connecting hole, and the big flow is just great towards through-hole 4 of solid fixed ring 1 direction, make the flow be from the center of book formula membrane toward outer the expansion, flow from the other end again through a book.
