Description

Technical Field

[0001] The present invention relates to the field of pipeline parts, in particular to a scale inhibitor and a pipeline system. Background Art

[0002] In household water systems, tap water contains insoluble deposits formed by calcium and magnesium ions. These substances, when dissolved in water or after prolonged use, can deposit on the surfaces of pipes and water-related equipment, forming scale. This phenomenon can lead to a reduction in pipe diameter or even blockage, resulting in accidents such as pipe ruptures. It also reduces the thermal efficiency of terminal heating equipment, wastes energy, and poses more serious health risks (such as kidney stones). To prevent this, three common descaling methods are: mechanical—scraping off surface scale with tools; chemical—using citric acid, acetic acid, hydrochloric acid, or active materials; and physical—microcurrent descaling. However, mechanical methods are time-consuming and labor-intensive, and their removal is not thorough. While chemical methods can quickly and effectively remove scale, the chemical elements themselves can cause greater damage to the piping system. Therefore, physical descaling is currently the most scientific, effective, and healthy descaling method.

[0003] Microcurrent descaling is a scale prevention device made of catalyst alloy as anti-scaling filter element. The basic design idea of ​​this type of device is to use the special function of catalyst alloy to continuously release free electrons into the water to prevent the aggregation of scale-forming anions such as carbonate, bicarbonate, sulfate and cations such as calcium and magnesium in the water, thereby achieving scale prevention of the water body. Figure 26 As shown, existing water treatment devices using catalytic alloys, regardless of whether the catalytic alloy core adopts straight holes, spiral holes, blades, spiral blades, rotating blades or even granular or scattered sheet structures, require a large number of unit arrangements and combinations to achieve the contact area required for scale inhibition, thereby making the entire scale inhibition channel too narrow and long in design, and placing greater requirements on the equipment installation environment. At the same time, the narrow and long channel has a negative impact on the water flow rate and pressure.

[0004] In view of this, this application is hereby filed. Summary of the Invention

[0064] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0065] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0066] Please refer to Figure 1-5 As shown, this embodiment provides a scale inhibitor 100, comprising a connector 110, a scale inhibition shell 150 and a scale inhibition core assembly 130, wherein the scale inhibition shell 150 is connected to the connector 110, and the scale inhibition core assembly 130 is disposed in the scale inhibition shell 150;

[0067] like Figure 7 As shown, the connector 110 has an inlet channel 117 and an outlet channel 118 that are isolated from each other. Figure 7 The middle water inlet 117 and the water outlet are indicated by arrow-shaped curves;

[0068] The scale-inhibiting core assembly 130 includes a water drive assembly 170 and a rotating shaft 131, an inner scale-inhibiting sheet assembly 134, a cylindrical frame 133 and an outer scale-inhibiting sheet assembly 132 which are coaxially arranged from the inside to the outside.

[0069] The cylindrical frame 133 and the scale inhibitor shell 150 form a water inlet channel 141 in the shell, and the water inlet channel 117 is connected to the water inlet channel 141 in the shell to form the scale inhibitor water inlet channel 101 ( Figure 3(Indicated by a curved line with an arrow in the middle), the external scale-preventing sheet group 132 is disposed in the water inlet channel 141 in the shell. The external scale-preventing sheet group 132 includes a plurality of external scale-preventing sheets 132a. The plurality of external scale-preventing sheets 132a are disposed on the outer wall of the cylindrical frame 133 and are sequentially arranged along the length thereof. Each external scale-preventing sheet 132a is provided with a plurality of first spiral guide structures 132b for causing water to flow in the same spiral direction.

[0070] The inner space of the cylindrical frame 133 is the water outlet channel 142 in the shell, and the end of the water inlet channel 141 in the shell away from the water inlet channel 117 is connected to the water outlet channel 142 in the shell;

[0071] The internal scale-preventing sheet group 134 includes a plurality of internal scale-preventing sheets 134a, which are arranged on the rotating shaft 131 and arranged in sequence along the length thereof. Each internal scale-preventing sheet 134a is provided with a plurality of second spiral guide structures 134b for causing water to flow in the same spiral direction.

[0072] The outlet channel 142 in the shell, which is close to the end of the connector 110, and the outlet channel 118 form the scale inhibitor outlet channel 102 ( Figure 3 Indicated by a curved line with an arrow in the middle);

[0073] The multiple external scale-preventing sheets 132a contained in the external scale-preventing sheet group 132 are all made of metal materials, and the materials of the multiple external scale-preventing sheets 132a are not all the same, or the multiple external scale-preventing sheets 132a contained in the external scale-preventing sheet group 132 are coated with metal coatings, and the materials of the metal coatings on the multiple external scale-preventing sheets 132a are not all the same; and / or, the multiple internal scale-preventing sheets 134a contained in the internal scale-preventing sheet group 134 are all made of metal materials, and the materials of the multiple internal scale-preventing sheets 134a are not all the same, or the multiple internal scale-preventing sheets 134a contained in the internal scale-preventing sheet group 134 are coated with metal coatings, and the materials of the metal coatings on the multiple internal scale-preventing sheets 134a are not all the same.

[0074] The aforementioned "the material of the plurality of external scale-preventing sheets 132a is not all the same" means that any one of the plurality of external scale-preventing sheets 132a is made of a different material than any other external scale-preventing sheets 132a. Alternatively, one external scale-preventing sheet 132a may be made of the same material as some of the other external scale-preventing sheets 132a, while some of the other external scale-preventing sheets 132a are made of different materials. Similarly, the explanation regarding "the material of the metal coating on the plurality of external scale-preventing sheets 132a is not all the same" is the same as above, and similar descriptions regarding the plurality of internal scale-preventing sheets 134a are also the same as above.

[0075] The scale inhibitors made of different metals or metal layers with different potentials are arranged in multiple levels to generate microcurrent. Under the action of microcurrent, the shape of CaCO3 crystals changes from "marble structure" to "aragonite structure", such as Figure 27 As shown, the scale layer is gradually dissolved, loosened and falls off, thereby achieving the effect of scale inhibition and prevention.

[0076] In the scale inhibitor 100 provided in the embodiment of the present application, water enters the scale inhibitor 100 from the water inlet 117 of the connector 110, flows through the water inlet channel 141 in the shell, and under the guiding action of the first spiral guide structure 132b, the water enters in a turbine rotation. When the water flows into the bottom of the scale inhibition shell 150, it is diverted into the water outlet channel 142 in the shell, and under the guiding action of the second spiral guide structure 134b, the water is discharged in a turbine rotation. The spiral vortex is equivalent to increasing the flow channel length, thereby increasing the contact area with the scale inhibition sheet, thereby improving the sufficient effect. Water flows in and out of the scale inhibitor 100 provided in the present application in a vortex state. During this process, it undergoes two-stage scale inhibition treatment by the internal scale inhibition sheet 134a and the external scale inhibition sheet 132a, which can achieve a sufficient scale inhibition effect. Moreover, the structure of the scale inhibitor 100 provided in the present application is different from the installation position of the existing scale inhibitor 100. The scale inhibitor 100 of the present application can be installed at the valve position and combined with the valve, or it can be combined with components such as filters and pressure gauges without being installed in the water supply pipe, and there is no problem of narrow and long water flow channels.

[0077] The scale inhibitor 100 provided in the embodiment of the present application is described in more detail below:

[0078] like Figure 3 、 4 As shown in Figures , 6, 7 and 24, the connecting body 110 of the scale inhibitor 100 includes a valve core assembly 112, a valve housing 113 and a hand wheel 111.

[0079] The valve housing 113 is connected to the scale inhibition housing 150. The valve housing 113 has an installation port 121 for mounting the valve core assembly 112, and a water outlet 123, located opposite the installation port 121 and connected to the water outlet channel 142 within the housing. One end of the valve core assembly 112 is installed within the valve housing 113 through the installation port 121. The other end is a handwheel connection end 128, which extends into the valve housing 113 and connects to the center of the handwheel 111. A seal 122 is provided at the end of the valve core assembly 112 within the valve housing 113. By turning the handwheel 111, the seal 122 can be moved to block the water outlet 123, and can also be moved to release the seal 122 from blocking the water outlet 123. Turning the handwheel 111 causes the valve stem within the valve core assembly 112 to extend and retract, thereby moving the seal assembly. This is a common valve structure and will not be described in detail here.

[0080] When the seal 122 is away from the water outlet 123, the valve opens and water flows into the scale inhibition shell. When the seal 122 moves to the upper end of the water outlet 123 to close the water outlet 123, the valve closes, the water flow is cut off, and the scale inhibition core assembly 130 stops working.

[0081] It should be noted that the connector 110 can be the above-mentioned valve for closing and opening the water channel, or it can be combined with equipment components such as filters and pressure gauges to play multiple roles.

[0082] like Figure 7 As shown, the top inner wall of the valve housing 113 corresponding to the mounting opening 121 is provided with a first internal thread 125, and the outer wall of the valve core assembly 112 is provided with a first external thread 127. The first internal thread 125 and the second external thread 152 cooperate to achieve a threaded connection between the valve assembly and the valve housing 113. The bottom inner wall of the valve housing 113 is provided with a second internal thread 126, and the top outer wall of the scale inhibition housing 150 is provided with a second external thread 152. The second internal thread 126 and the second external thread 152 cooperate to achieve a threaded connection between the valve housing 113 and the scale inhibition housing 150.

[0083] like Figure 3 、 8 As shown in Figure 9, the scale inhibition core assembly 130 also includes a water inlet member 160. The water inlet member 160 is annular and is sleeved on the upper end of the cylindrical skeleton 133. A plurality of first snap protrusions 138 are provided on the inner side of the ring, and a plurality of second snap protrusions 163 are provided on the top outer wall of the cylindrical skeleton 133. The setting positions and setting numbers of the plurality of first snap protrusions 138 correspond to those of the second snap protrusions 163. When it is sleeved on the cylindrical skeleton 133, the first snap protrusions 138 and the corresponding second snap protrusions 163 are engaged with each other.

[0084] The outer wall of the water inlet member 160 is also evenly provided with a plurality of first latching protrusions 162, and the upper inner wall of the scale inhibition shell 150 is provided with a plurality of first latching protrusion matching grooves 153. The number and distribution positions of the plurality of first latching protrusions 162 are the same as those of the first latching protrusion matching grooves 153. When the water inlet member 160 is sleeved on the cylindrical frame 133 and arranged in the scale inhibition shell 150, the first latching protrusions 162 are just embedded in the corresponding first latching protrusion matching grooves 153.

[0085] The water inlet member 160 is located between the water inlet channel 117 and the inlet channel 141 within the shell. It is evenly distributed with multiple spiral diversion holes 161 that align with the spiral diversion direction of the first spiral diversion structure 132b. When water enters the scale inhibitor 100 from the water inlet channel 117, it is initially guided in a spiral by the spiral diversion holes 161 before entering the inlet channel 141 within the shell. The spiral diversion holes 161 align with the first spiral diversion structure 132b in this direction.

[0086] like Figure 3 、 12 As shown in Figure 13, the external scale-preventing sheet 132a includes a first annular plate 132c, the inner edge of the first annular plate 132c is connected to the cylindrical skeleton 133, each first spiral guide structure 132b includes a first through hole 132d and a first guide sheet 132e, the first through hole 132d is arranged on the first annular plate 132c, one end of the first guide sheet 132e is connected to the edge of the first through hole 132d corresponding to the first through hole 132d of the first annular plate 132c, and the other end is inclined and extends toward one end away from the connector 110.

[0087] The water flow from the spiral guide hole 161 reaches the outer scale-blocking plate 132a in a spiral direction, passes through the first through hole 132d, and is spirally guided again under the action of the first guide plate 132e, so that the water flow is as follows: Figure 13 The water flow path shown is shown. The inner diameter of the first annular plate 132c is the same as the outer diameter of the cylindrical frame 133, and the outer diameter of the first annular plate 132c is the same as the inner diameter of the scale inhibition shell 150. This arrangement can minimize the water flow from flowing through the gap between the first annular plate 132c and the inner wall of the scale inhibition shell 150, or from the gap between the first annular plate 132c and the outer wall of the cylindrical frame 133 without spiral guidance.

[0088] like Figure 3 、 10 As shown in Figure 13, the outer wall of the cylindrical frame 133 is provided with a plurality of inlet and outlet grooves 143, and the plurality of inlet and outlet grooves 143 are evenly distributed along the circumference of the cylindrical frame 133. Each inlet and outlet groove 143 is parallel to the length direction of the cylindrical frame 133, and one end of the inlet and outlet groove 143 extends to the end face of the cylindrical frame 133 near the valve. The outer wall of the cylindrical frame 133 is also provided with a plurality of groups of rotational positioning grooves 144 corresponding to the plurality of inlet and outlet grooves 143. Each group of rotational positioning grooves 144 includes a plurality of groups of rotational positioning grooves 144 along the cylindrical frame. The skeleton 133 is provided with rotational latching slots 144 evenly distributed along its length. Each of these rotational latching slots 144 communicates with a corresponding entry / exit slot 143. Each rotational latching slot 144 is perpendicular to the corresponding entry / exit slot 143 and comprises a rotational slot 145 and a fixed slot 146. One end of the rotational slot 145, facing away from the valve, communicates with the side of the fixed slot 146, facing closer to the valve. The other end of the rotational slot 145 communicates with the entry / exit slot 143. The inner diameter of the first annular plate 132c is equal to the outer diameter of the cylindrical skeleton 133. A plurality of second latching protrusions 139 are disposed on the inner side of the first annular plate 132c. The number and location of the plurality of second latching protrusions 139 correspond to the plurality of entry / exit slots 143, and the protrusion distance of the second latching protrusions 139 is less than or equal to the depth of the entry / exit slot 143.

[0089] When installing the outer scale-preventing sheet 132a on the outer wall of the cylindrical frame 133, align the multiple second latching protrusions 139 with the multiple inlet and outlet grooves 143 one by one. Then, push the outer scale-preventing sheet 132a along the inlet and outlet grooves 143 to the position where the rotation latching slot is located. Rotate the outer scale-preventing sheet 132a so that the second latching protrusions 139 enter the rotation groove 145. When the outer scale-preventing sheet 132a is fully rotated, push the second latching protrusion 139 downward into the fixed groove 146. This completes the installation of the outer scale-preventing sheet 132a. To remove the outer scale-preventing sheet 132a, the above process is reversed.

[0090] like Figure 3 、 14 -16, the scale inhibition core assembly 130 also includes a water drive assembly 170, which is arranged at one end of the scale inhibition shell 150 away from the connector 110. The water drive assembly 170 includes a water drive shell 171 and an impeller 177. The water drive shell 171 is provided with at least two opposite tangential water inlets 172. The rotating shaft 131 passes through the water drive shell 171 and is connected to the center of the impeller 177. The water inlet direction of the tangential water inlet 172 is toward the blades of the impeller 177; the end of the water inlet channel 141 in the shell away from the water inlet channel 117 is connected to the tangential water inlet 172.

[0091] Part of the water flowing from the water inlet channel spirally to the bottom of the scale-inhibiting shell enters the water outlet channel 142 in the shell from the bottom of the cylindrical frame 133, and part of the water flows tangentially into the water drive assembly 170. The tangentially entering water flow impacts the blades of the water wheel, causing the impeller 177 to rotate. The rotation of the water wheel drives the rotation of the shaft 131 connected to it. The water flow entering the water drive assembly 170 impacts the water wheel, causing it to rotate, and then is discharged from the opposite tangential water inlet 172 and finally enters the water outlet channel 142 in the shell. It should be noted here that the location of the tangential water inlet 172 needs to ensure that the rotation direction of the impeller 177 is consistent with the diversion direction of the internal scale-inhibiting sheet 134a.

[0092] By setting the water drive assembly 170, the disturbance of the inner circle water flow is accelerated to form a faster and more rapid vortex, so that the scale inhibition effect is further improved.

[0093] A shaft sleeve 176 is provided at the center position of the impeller 177. The inner wall of the shaft sleeve 176 is non-cylindrical. The rotating shaft 131 is inserted into the shaft sleeve 176, and the part inserted into the shaft sleeve 176 is exactly matched with the inner wall of the shaft sleeve 176. In this way, the rotating shaft 131 can be driven to rotate when the impeller 177 rotates.

[0094] A first mounting hole 173 is provided at the center of the bottom of the water drive housing 171. A first steel ball 174 is disposed within the first mounting hole 173. One end of the rotating shaft 131 is a first arc end 147, which is inserted into the first mounting hole 173 and abuts against the first steel ball 174. This arrangement minimizes the contact area between the end of the rotating shaft 131 and other components, reducing resistance.

[0095] like Figure 3 、 17 As shown in Figures 1 and 2, the scale inhibition core assembly 130 also includes a water drive connecting seat 180, and the water drive assembly 170 is arranged in the water drive connecting seat 180; the water drive connecting seat 180 includes a base 182 and a cylindrical connector 181 arranged on the base 182, and the end of the cylindrical connector 181 away from the base 182 is connected to the cylindrical skeleton 133, and the outer wall of the cylindrical connector 181 is provided with a plurality of spiral guide blades 183 consistent with the spiral guide direction of the first spiral guide structure 132b, and a plurality of through holes 184 are provided on the side wall of the cylindrical connector 181, and the through holes 184 are located between the base 182 and the spiral guide blades 183. The water inlet channel 141 in the shell is connected to the tangential water inlet 172 and the end of the cylindrical skeleton 133 away from the connector 110 through the plurality of through holes 184, and the water drive shell 171 is connected to the base 182.

[0096] When the water flow spirally guided through the water inlet channel 141 in the shell reaches the bottom of the scale inhibition shell 150, it will be guided again by the spiral guide blades 183 and enter the water drive assembly 170 and the water outlet channel 142 in the shell through multiple through holes 184.

[0097] like Figure 3 、 17 As shown in Figures 18 and 24, a plurality of limiting protrusions 151 are provided at the bottom of the side wall of the scale inhibition shell 150, and a plurality of limiting grooves 186 corresponding to the number and position of the plurality of limiting protrusions 151 are provided at the bottom wall edge of the base 182. Each limiting protrusion 151 is inserted into the corresponding limiting groove 186, thereby preventing the rotating water flow from driving the scale inhibition core assembly 130 to rotate together.

[0098] A clamping ring 185 is provided at the bottom of the base 182 , and a plurality of clamping members 175 are provided at the bottom of the water drive housing 171 . The clamping ring 185 and the plurality of clamping members 175 engage with each other to achieve the connection between the base 182 and the water drive housing 171 .

[0099] like Figure 3 and Figure 19As shown, the internal scale-preventing sheet 134a includes a second annular plate 134c, the inner edge of the second annular plate 134c is connected to the rotating shaft 131, each first spiral guide structure 132b includes a second through hole 134d and a second guide sheet 134e, the second through hole 134d is arranged on the second annular plate 134c, one end of the second guide sheet 134e is connected to the edge of the second through hole 134d of the second annular plate 134c corresponding to the other end is inclined and extends toward one end close to the connector 110.

[0100] Water entering the water outlet channel 142 passes through the second through-hole 134d and, after contacting the second guide vane 134e, is further directed by the second guide vane 134e. The outer diameter of the second annular plate 134c is the same as the inner diameter of the cylindrical frame 133. This minimizes the risk of unguided water flowing through the gap between the second annular plate 134c and the inner wall of the cylindrical frame 133.

[0101] The first spiral guide structure 132b provided on the second annular plate 134c is distributed in an annular shape, which may be one circle or multiple circles, such as Figure 19 The following are 2 circles, Figure 20 As shown, Figure 20 The left picture is a water flow path diagram after the water flows through the second spiral guide structure 134b of the outer circle, and the right picture is a water flow path diagram after the water flows through the second spiral guide structure 134b of the inner circle.

[0102] like Figure 3 and 21 As shown, the rotating shaft 131 is a square rotating shaft 131, i.e., its cross-section is square. A central mounting hole 134f is provided at the center of the second annular plate 134c. Each internal scale-preventing sheet 134a is mounted on the rotating shaft 131 through the central mounting hole 134f. Due to the shape of the rotating shaft 131 and the central mounting hole 134f, the internal scale-preventing sheet 134a can be rotated when the rotating shaft 131 rotates.

[0103] The scale inhibition core assembly 130 also includes multiple pairs of limiting plates 135 with the same number as the internal scale inhibition plates 134a. Multiple pairs of limiting slots 136 corresponding to the number of the multiple pairs of limiting plates 135 are evenly spaced in sequence along the length direction on the rotating shaft 131. Each pair of limiting slots 136 consists of two slot bodies 136a, and each pair of limiting plates 135 consists of two C-shaped plates 135a. The inner side of each C-shaped plate 135a is inserted into a slot body 136a in an embracing manner so that each pair of limiting plates 135 clamps a second annular plate 134c, thereby limiting the internal scale inhibition plate 134a in the length direction of the rotating shaft 131.

[0104] like Figure 22 and 23As shown, the scale inhibition core assembly 130 also includes a water outlet member 190, which is arranged at one end of the cylindrical frame 133 close to the connector 110. The water outlet member 190 is provided with a plurality of water holes 191 connected to the water outlet channel 142 in the shell, and each water hole 191 is connected to the water outlet channel 118.

[0105] A second mounting hole 192 is provided on the side of the water outlet member 190 away from the connector 110. The other end of the rotating shaft 131 is inserted into the second mounting hole 192. The end of the rotating shaft 131 inserted into the second mounting hole 192 is a second arc end 148. A second steel ball 193 is disposed in the second mounting hole 192, and the second arc end 148 abuts against the second steel ball 193.

[0106] like Figure 10 、 11 As shown in Figures 22 and 23, the lower part of the water outlet member 190 is inserted into the upper part of the cylindrical frame 133, and the lower peripheral wall 195 of the water outlet member 190 is exactly matched with the inner wall of the upper part of the cylindrical frame 133. The upper edge of the water outlet member 190 abuts against the end face of the valve shell 113 located at the water outlet 123. In this way, the scale inhibitor inlet channel 101 and the scale inhibitor outlet channel 102 can be isolated, preventing water from flowing out of the water outlet channel 118 without scale inhibition treatment after entering the scale inhibitor 100.

[0107] The bottom outer wall of the water outlet part 190 is provided with an annular locking protrusion 194, and the top of the cylindrical frame 133 is provided with an annular locking groove 149. When the lower part of the water outlet part 190 is inserted into the upper part of the cylindrical frame 133, the water outlet part 190 is downward, so that the annular locking protrusion 194 is snapped into the annular locking groove 149, thereby realizing the snap connection between the water outlet part 190 and the cylindrical frame 133.

[0108] The lower circumferential wall 195 of the water outlet member 190 is also provided with a sealing groove 196. A sealing ring is installed within the sealing groove 196 to achieve a seal with the cylindrical frame 133. It should be noted that to ensure complete isolation between the inlet 117 and outlet 118 of the scale inhibitor 100, as well as to ensure internal sealing of the scale inhibitor 100, sealing rings are installed at most of the joints between components in other parts of the scale inhibitor 100 of this embodiment. Since sealing ring technology is well-known, it will not be elaborated on here.

[0109] To sum up, water flows in and out of the scale inhibitor 100 provided in the present application in a vortex state. During this process, it undergoes two-stage scale inhibition treatment by the internal scale inhibition sheet 134a and the external scale inhibition sheet 132a, which can achieve a sufficient scale inhibition effect; and, the structure of the scale inhibitor 100 provided in the present application is different from the installation position of the existing scale inhibitor 100. The scale inhibitor 100 of the present application can be installed at the valve position and combined with the valve, or it can be combined with components such as filters and pressure gauges without being installed in the water supply pipe, and there is no problem of narrow and long water flow channels.

[0110] like Figure 25 As shown, an embodiment of the present application also provides a pipeline system, including a first section of a pipe body 11, a second section of a pipe body 12 and a scale inhibitor 100 provided in an embodiment of the present application, wherein the first section of the pipe body 11 is connected to the water inlet 117, and the second section of the pipe body 12 is connected to the water outlet 118.

[0111] Since the pipeline system includes the scale inhibitor 100 provided in the embodiment of the present application, the pipeline system is not prone to scaling.

[0112] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
