In a specific embodiment, the utility model provides a scale inhibition filter core, including the barrel 5 that is used for holding the antisludging agent, install respectively in two interior end caps 4 in barrel 5 both ends, press respectively in two sealing washer 3 of 4 terminal surfaces departments in two, assemble respectively in two of 5 both ends tip of barrel bury formula end cover 2 to and assemble respectively in two interior claws 1 of buryying formula end cover 2 department, the terminal surface top of interior claw 1 is on sealing washer 3, has the through-hole that makes liquid pass through on interior end cap 4.

In the structure, the scale inhibition filter element comprises a cylinder body 5, two inner end covers 4, two seal rings 3, two embedded end covers 2 and two inner claws 1, wherein a hollow cavity is arranged in the middle of the cylinder body 5, a scale inhibitor is placed in the cavity of the cylinder body 5, and the scale inhibitor is placed in the cylinder body 5 which is an independent part.

The two ends of the cylinder 5 are provided with an advancing water gap and a rear water outlet, the two inner end covers 4 are respectively arranged on the advancing water gap and the rear water outlet at the two ends of the cylinder 5, and the inner end covers 4 are used for preventing scale inhibitor particles from being flushed out.

The inner end cover 4 is provided with a through hole, liquid can pass through the through hole, and the scale inhibitor is prevented from rushing to one side due to high pressure of inlet water and being blocked due to the reduction of the dissolved volume of the scale inhibitor particles. The two sealing rings 3 are respectively pressed at the end faces of the two inner end covers 4, preferably, the sealing rings 3 are O-shaped rings, and the outer sides of the sealing rings 3 are in interference fit with the inner wall of the cylinder body 5 to perform sealing treatment.

The two embedded end covers 2 are respectively assembled at the end parts of the two ends of the cylinder 5, and the two embedded end covers 2 are relatively fixedly connected with the cylinder 5 and cannot be disassembled after assembly. In particular, the side wall of the buried end cap 2 may have barbs that are inserted into the inner wall of the barrel 5.

The two inner claws 1 are respectively assembled at the two embedded end covers 2, the end surfaces of the inner claws 1 are propped against the sealing ring 3, and the sealing ring 3, the embedded end covers 2 and the inner claws 1 form a quick-insertion type scale inhibition filter core. This antisludging filter core can use inside the filter core at the machine, also can externally connect outside the machine, uses the third of the ten minutes quick connector, and it is convenient and do not account for the space to change, can guarantee the suitable length of water, and the packing that makes inside hold sufficient antisludging agent of volume closely knit degree can influence the water of crossing.

The scale inhibition filter element is only a preferred scheme, and is not particularly limited to the preferred scheme, because of the design of the three-tap socket, the maximum size of the inner cavity of the cylinder 5 is determined by the inner diameter of the sealing ring 3, the sealing ring 3 needs to be supported and limited, if the sealing ring is supported by a step surface, the size of the inner cavity is reduced, at least two supporting ribs are selected to be arranged on the inner wall of the cavity of the cylinder 5, the inner end cover 4 is supported on the end surface of each supporting rib, the inner part of the cavity is supported by the supporting ribs, the inner capacity is increased, the inner end cover 4 is used as the supporting surface of the sealing ring 3, the structure is simple, and the inner end cover 4 and the sealing ring 3 are easy to install.

On the basis of the above-described embodiments, the through-hole includes a water passing opening that is opened to the side of the inner end cap 4, through which liquid can pass. The water passing opening and the supporting rib are arranged in a staggered mode, so that the situation that the size of a sealing part is limited to change due to the fact that the water passing opening and the supporting rib are arranged oppositely when the water passing opening and the supporting rib are installed is avoided, and the water passing opening is guaranteed to pass through water smoothly.

On the basis of each above-mentioned specific embodiment, the quantity of brace rod and the quantity inequality of crossing water opening, for example 4 brace rods have been designed on

barrel

5, 4 brace rods are evenly distributed in circumference, and the side of interior end cover 4 sets up 3 and crosses water openings, and 3 are crossed water opening and are evenly distributed in circumference, and the brace rod and the water opening can not be totally right up this moment, can misplace and arrange all the time, guarantee that the water opening crosses water smoothly. Of course, the staggered arrangement realized by the unequal number of the supporting ribs and the number of the water passing openings is only a preferred embodiment, is not unique, and can be avoided by the angle dislocation of the water passing openings and the supporting ribs.

On the basis of the above embodiments, because the barrel 5 is provided with a plurality of support ribs, and the scale inhibitor is generally round particles, after compaction, because the corners of the support ribs are straight surfaces, unless the support ribs are powdery particles such as flour, gaps are formed for water to pass through; and because the support rib of the cylinder 5 and the inner end cover 4 are laterally provided with the water passing opening, the high pressure of the inlet water is blocked by the inner end cover 4, so that the scale inhibitor cannot be directly flushed to one side, the passing water can generate turbulent flow, the scale inhibitor can be better overturned and dissolved, and the purpose of better scale inhibition effect is achieved.

In another more reliable embodiment, on the basis of any one of the above embodiments, the middle of the end face of the inner end cover 4 is provided with a long-strip-shaped groove or/and a semi-fan-shaped groove, the through hole comprises the long-strip-shaped groove or/and the semi-fan-shaped groove, the scale inhibitor is slowly reduced to spherical particles in the dissolving process, the spherical particles can pass through the groove only after reaching the minimum size of the groove, and the long-strip-shaped groove and the semi-fan-shaped groove are small in size, so that the particles which can pass through the groove cannot influence the filtration of the filter element.

Because the scale inhibitor is slowly reduced to spherical particles in the dissolving process, the spherical particles can pass through only after reaching the minimum size of the open groove and become just clamped in the groove, namely when the scale inhibitor particles pass through, a gap of water passing still exists between the elongated groove or/and the semi-fan-shaped groove and the scale inhibitor particles, and the blockage is prevented. Specifically, the middle of the end face of the inner end cover 4 is provided with a strip-shaped groove, and when scale inhibitor particles pass through, the size of the scale inhibitor particles is equal to the width of the strip-shaped groove and is smaller than the arc length of the strip-shaped groove. When the middle of the end surface of the inner end cover 4 is provided with scale inhibitor particles, the scale inhibitor particles are internally tangent in the semi-fan-shaped groove.

In another more reliable embodiment, on the basis of any of the above embodiments, the end surface of the inner end cap 4 contacting with the three-way pipe is an arc-shaped surface, and as the position indicated by the middle arrow in fig. 4, the end surface of the inner end cap 4 and the end surface of the three-way pipe cannot be completely attached, so that there is a gap between the inner end cap 4 and the contact surface of the three-way pipe for water flow to pass through.

The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.

The scale inhibition filter element provided by the utility model is introduced in detail. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the method and its core ideas of the present invention.
