Description

Technical Field

[0001] The utility model relates to a water flow scale-blocking impeller which can be applied to a water flow pipeline. The utility model also relates to a water pump. Background Art

[0002] A gas water heater is a gas appliance that uses gas as fuel. After burning and heating, it transfers heat energy to cold hard water flowing through a heat exchanger, heating the cold hard water into hot water. It is mostly used in households and can be used immediately after being turned on. After a gas water heater has been used for a long time, scale will adhere to the inside of its pipes. Due to the long-term use of existing gas water heaters, the scale inside is thick, especially at the outlet of the water pump, which makes it difficult to clean and causes pipe blockage, affecting the normal use of the water pump. Utility Model Content

[0003] The first technical problem to be solved by the utility model is to provide a water softening impeller capable of preventing scale in view of the above technical status quo.

[0004] The second technical problem to be solved by the utility model is to provide a scale-resistant water pump in view of the above-mentioned technical status quo.

[0005] The utility model solves the above-mentioned first technical problem by adopting a technical solution: a soft water impeller, characterized in that it includes

[0006] A first bracket, having a plurality of first water holes arranged in an annular shape on its end surface;

[0007] A second bracket, disposed on the lower end surface of the first bracket and having a second water passing hole arranged in an annular shape corresponding to the first water passing hole; and

[0008] The blade is made of a scale-inhibiting alloy material or coated with a scale-inhibiting alloy material. The blade is arranged between the first bracket and the second bracket. The end surface of the blade part is located in the flow channel formed by the first water hole and the second water hole to form a flushing surface.

[0009] The scouring surface of the blade is provided with flow holes, or a water flow gap is formed between the outer periphery of the blade and the inner wall of the flow channel.

[0010] Preferably, the lower end surface of the first bracket has an upper built-in groove, and the upper end surface of the second bracket has a corresponding lower built-in groove, and the blade is arranged in the area surrounded by the upper built-in groove and the lower built-in groove to be limited.

[0011] Preferably, the first bracket includes a first annular portion and a first grille radially arranged in the first annular portion, and the first water hole is formed between adjacent first grilles and the inner wall of the first annular portion; the second bracket includes a second annular portion and a second grille radially arranged in the second annular portion, and the second water hole is formed between adjacent second grilles and the inner wall of the second annular portion.

[0012] The first bracket and the second bracket are preferably integrated into one structure as follows: the lower end surface of the first annular portion has a groove, and correspondingly, the upper end surface of the second annular portion has a convex point that matches the groove.

[0013] The first bracket, the blades and the middle of the second bracket are penetrated to form a central flow channel, and the blades are arranged with a plurality of intermediate flow holes in a ring shape around the central flow channel. The intermediate flow holes are located in the flow channel formed by the first water hole and the second water hole, and a water gap is formed between the outer periphery of the blade and the inner wall of the flow channel. The water flow is divided into three parts and flows through the soft water impeller from the central flow channel, the intermediate flow holes and the water gap, so that the flushing water is maintained and the flushing area is guaranteed. Each area of ​​the blade can be fully in contact with the water flow. The more water molecules are in contact with the anti-scaling alloy material, the better the anti-scaling and descaling effect.

[0014] The blades are made of multi-element alloy material.

[0015] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: a water pump, characterized in that it includes a pump body, a water outlet section and a soft water impeller, the aforementioned water outlet section is connected to the water outlet port of the pump body, and the aforementioned soft water impeller is arranged in the inner cavity of the water outlet section.

[0016] There are two ways to set the soft water impeller:

[0017] The first one is that a connecting sleeve is provided in the water outlet section, and the soft water impeller is arranged in the connecting sleeve.

[0018] In the second, the soft water impeller is directly arranged in the inner cavity of the water outlet end.

[0019] Preferably, the pump body is a centrifugal pump. Further, the water outlet section is connected to the water outlet end of the volute of the pump body.

[0020] Compared with the prior art, the utility model has the advantages of combining the blades, the first bracket and the second bracket into a combined integrated component, which is easy to install and disassemble. When the water flows through the soft water impeller, it continuously washes the flushing surface of the blades, so that the water flow and the scale-inhibiting alloy material of the blades are fully in contact, thereby achieving the effect of scale prevention and descaling. The scale-inhibiting alloy material is only used on the blades, which has a lower overall cost and is easy to manufacture. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] Embodiment 1, as Figure 1 , Figure 2 and Figure 3 As shown, the water pump in this embodiment is a centrifugal pump including a pump body 1, a water outlet section 3 and a water softening impeller 5. The pump body 1 is provided with an impeller 2 and a volute 11, the volute 11 has a water inlet 12, the water outlet section 3 is connected to the water outlet end of the volute 11 of the pump body 1, and the water outlet section 3 has a water outlet 31. The water softening impeller 5 is arranged in the inner cavity of the water outlet section 3. A connecting sleeve 4 is arranged in the water outlet section 3, and the water softening impeller 5 is arranged in the connecting sleeve 4.

[0029] Combination Figure 3 and Figure 4 As shown, the soft water impeller in this embodiment includes a first bracket 51, a second bracket 52 and a blade 53. The first bracket 51 has a plurality of first water holes 513 arranged in a ring shape on the end surface. The second bracket 52 is arranged on the lower end surface of the first bracket 51 and has second water holes 523 arranged in a ring shape corresponding to the first water holes 513.

[0030] The blade 53 is arranged between the first bracket 51 and the second bracket 52, and part of the end surface of the blade 53 is located in the flow channel formed by the first water hole 513 and the second water hole 523 to form an scouring surface; the blade 53 in this embodiment is made of a multi-component alloy material. The multi-component alloy material is a special multi-component alloy (copper-based catalyst alloy) for scale inhibition and descaling. It is an alloy material prepared by high-temperature smelting of various metal elements with different electronegativity, mainly copper, zinc, and nickel. The multi-component alloy material is formed by strictly controlling the composition ratio of various elements and adopting special processing technology. The different potentials of different alloys are used to form a micro-electrochemical system, change the characteristics of water, inhibit the combination of calcium and magnesium with acid ions, and inhibit the formation of scale, thereby achieving a scale inhibition effect. At the same time, the scale is transformed from a dense calcite state to a loose aragonite state.

[0031] The first bracket 51 has an upper built-in groove 514 on its lower end surface, and the second bracket 52 has a corresponding lower built-in groove 524 on its upper end surface. The blade 53 is disposed in the area surrounded by the upper built-in groove 514 and the lower built-in groove 524 to be limited.

[0032] The first bracket 51 includes a first annular portion 511 and first grilles 512 radially arranged in the first annular portion 511, and a first central hole 515 is formed in the middle thereof. A first water hole 513 is formed between the adjacent first grilles 512 and the inner wall of the first annular portion 511.

[0033] The second bracket 52 includes a second annular portion 521 and second grilles 522 radially arranged in the second annular portion 521, and a second central hole 525 is formed in the middle thereof. A second water hole 523 is formed between the adjacent second grilles 522 and the inner wall of the second annular portion 521.

[0034] The lower end surface of the first annular portion 511 has grooves and protrusions on both sides. Correspondingly, the upper end surface of the second annular portion 521 has a protrusion 526 that matches the groove of the first annular portion 511 and a groove 527 that matches the protrusion of the first annular portion 511.

[0035] A central flow passage 1 b is formed through the middle of the first bracket 51 , the blades 53 and the second bracket 52 , that is, the first central hole 515 , the third central hole 532 and the second central hole 525 constitute the central flow passage 1 b .

[0036] The blade 53 has a third center hole 532 at its center. The blade 53 has a plurality of intermediate flow holes 531 arranged in a ring shape around the third center hole 532. The intermediate flow holes 531 are located in a flow passage formed by the first water flow hole 513 and the second water flow hole 523. A water flow gap 1a is formed between the outer periphery of the blade 53 and the inner wall of the flow passage.

[0037] When water flows through the soft water impeller, the water flow is divided into three parts and flows through the soft water impeller from the central flow channel 1b, the middle flow hole 531 and the water gap 1a. This not only maintains the flushing water flow but also ensures the flushing area. Each area of ​​the blade can fully contact with the water flow. The more water molecules are in contact with the anti-scaling alloy material, the better the anti-scaling and descaling effect. The scouring surface of the blade ensures the impact of water flow, and the water flows around to ensure the water flow. At the same time, there are holes in the middle and center of the blade to ensure the impact amount of each area. The design of directional flow can also reduce some noise. The flow channel with multi-area holes and the flow of the outer circle reduce the generation of vortexes after the water flows through the blades. The multi-hole flow channel also applies multi-hole noise reduction technology to cut off some frequency noise. No vortex is formed after the water flows through, which reduces energy loss and sound.

[0038] Embodiment 2, as Figure 6 As shown, the water softening impeller 5 in this embodiment is directly arranged in the inner cavity of the water outlet section 3, and no connecting sleeve 4 is provided. Other structures refer to Example 1.
