[0025] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0026] like Figs. 1-2 As shown, an embodiment of this utility model provides a scale filtration device for the alkaline zone of a hypochlorous acid generator, comprising:

[0027] The filter tube 1 has an outlet 1011, an inlet 1021 and a scale discharge port 1031 arranged at intervals in the vertical direction. The scale discharge port 1031 is located at the lower end of the filter tube 1.

[0028] The water inlet pipe 2 includes a first pipe body 201 and a second pipe body 202. The first pipe body 201 extends radially along the filter pipe 1, and the second pipe body 202 extends axially along the filter pipe 1. The inner end of the first pipe body 201 is smoothly connected to the lower end of the second pipe body 202, and the outer peripheral wall of the first pipe body 201 is connected to the water inlet 1021.

[0029] A blowdown valve 3 is arranged at the blowdown port 1031.

[0030] According to the above technical scheme, the untreated lye water flows into the filter pipe 1 through the first pipe body 201 and the second pipe body 202, and is separated from the water scale by sedimentation. The water scale is accumulated at the bottom of the filter pipe 1, and the separated lye water is located above the water scale. The lye water is overflowed and discharged from the water outlet 1011. When the water scale accumulates to a certain degree, the blowdown valve 3 is opened, and the water scale is discharged from the blowdown valve 3 under the pressure of the lye water. Until the lye water appears at the blowdown valve 3, the blowdown valve 3 is closed, and the filtration is completed.

[0031] The filter pipe 1 has the water outlet 1011, the water inlet 1021 and the blowdown port 1031 arranged in the up-down direction. The blowdown port 1031 is located at the lower end of the filter pipe 1, and the water scale can be naturally sedimented at the bottom of the filter pipe 1 and smoothly discharged through the blowdown port 1031. The water outlet 1011 is arranged at the upper side of the water inlet 1021, and the separated lye water is overflowed and discharged from the water outlet 1011. The sedimentation separation path of the lye water is further extended, and the sedimentation separation effect is ensured. The first pipe body 201 extends radially along the filter pipe 1, and the second pipe body 202 extends axially along the filter pipe 1. The inner side end of the first pipe body 201 is smoothly connected to the lower end of the second pipe body 202. The direction of the untreated lye water entering the filter pipe 1 from the second pipe body 202 is upward, avoiding direct impact on the water scale at the bottom of the filter pipe 1, stirring the water scale, and ensuring the sedimentation separation effect.

[0032] Preferably, the upper end of the second pipe body 202 is provided with a flow expansion part 4, which is in the shape of a funnel with the outer diameter gradually increasing from bottom to top.

[0033] The flow expansion part 4 is in the shape of a funnel with the outer diameter gradually increasing from bottom to top. When the lye water flows into the filter pipe 1 from the second pipe body 202, the cross-sectional area of the flow expansion part 4 gradually increases in the up-down direction. Under the condition of constant flow, the water flow speed can be effectively slowed down, and the water flow flows into the filter pipe 1 in multiple directions, reducing the scouring of the water scale, so that the water scale can be stably deposited at the bottom of the filter pipe 1, which helps to improve the water scale separation efficiency.

[0034] Preferably, the filter pipe 1 includes a third pipe body 101, a fourth pipe body 102 and a fifth pipe body 103 arranged in the up-down direction and detachably arranged with each other. The water outlet 1011 is arranged on the third pipe body 101, the water inlet 1021 is arranged on the fourth pipe body 102, and the blowdown port 1031 is arranged at the lower end of the fifth pipe body 103.

[0035] Specifically, the lower end of the third pipe body 101 is provided with a first threaded part, the upper and lower ends of the fourth pipe body 102 are respectively provided with a second threaded part and a third threaded part, and the upper end of the fifth pipe body 103 is provided with a fourth threaded part. The first threaded part and the second threaded part are engaged with each other, and the third threaded part and the fourth threaded part are engaged with each other.

[0036] The water inlet pipe 2 is arranged on the fourth pipe body 102 through the water inlet 1021, and the third pipe body 101, the fourth pipe body 102 and the fifth pipe body 103 are detachable. If the water inlet pipe 2 is blocked, the fourth pipe body 102 can be directly removed and replaced, which is convenient to operate and has little effect on continuous filtration. Moreover, the third pipe body 101, the fourth pipe body 102 and the fifth pipe body 103 are detachable, so that the third pipe body 101 and the fifth pipe body 103 with different lengths can be selected according to actual conditions, and the flexibility and adaptability are high. Moreover, users can more easily access the position where scale accumulates, so as to perform complete cleaning. The structure is simple and convenient to maintain.

[0037] More preferably, an exhaust port 1012 is arranged on the upper end surface of the third pipe body 101, and the water outlet 1011 is arranged along the radial direction of the third pipe body 101.

[0038] By arranging the exhaust port 1012 on the upper end surface of the third pipe body 101, the gas in the filter pipe 1 can be effectively discharged, preventing the gas from being retained in the filter pipe 1. The retention of the gas can affect the normal flow of the water flow and the filtration effect, resulting in incomplete separation of the scale. The exhaust port 1012 can ensure smooth water flow, avoid the accumulation of air bubbles, and improve the filtration efficiency and scale separation capacity.

[0039] More preferably, the lower end of the fifth pipe body 103 is provided with a scale guiding part 5, the scale guiding part 5 is in the shape of a funnel with an increasing outer diameter from bottom to top, the upper end of the scale guiding part 5 is connected with the scale discharging port 1031, and the lower end of the scale guiding part 5 is connected with the scale discharging valve 3.

[0040] The funnel-shaped scale guiding part 5 can effectively guide the deposited scale to flow downward, ensuring that the scale can smoothly pass through the scale discharging port 1031. The funnel shape can generate pressure on the scale by guiding the water flow to be concentrated, so that the scale is more easily settled downward and collected, preventing the scale from remaining in the filter pipe 1.

[0041] Preferably, the water inlet end of the first pipe body 201 is provided with a pressure regulating valve (not shown in the drawings).

[0042] By adjusting the water flow pressure through the pressure regulating valve, the speed and flow rate of the water flow entering the filter pipe 1 can be accurately controlled, thereby optimizing the distribution of the water flow, so that the water flow can enter the filter pipe 1 more uniformly, which helps to improve the sedimentation efficiency of the scale, avoids the scale being carried away by the water flow or being unable to be effectively separated, and can improve the overall filtration effect of the filter device.

[0043] To sum up, the alkali area scale filtering device for hypochlorous acid generator is provided in the embodiment of the utility model, the filter pipe 1 has the water outlet 1011, the water inlet 1021 and the scale discharge port 1031 which are arranged in the up-down direction, the scale discharge port 1031 is located at the lower end of the filter pipe 1, the scale can be naturally settled to the bottom of the filter pipe 1 and be smoothly discharged through the scale discharge port 1031, the water outlet 1011 is arranged at the upper side of the water inlet 1021, the alkali water after settlement and separation is overflowed and discharged from the water outlet 1011, the settlement and separation path of the alkali water is further prolonged, and the settlement and separation effect is ensured, the first pipe body 201 extends in the radial direction of the filter pipe 1, the second pipe body 202 extends in the axial direction of the filter pipe 1, the inner side end of the first pipe body 201 is smoothly connected with the lower end of the second pipe body 202, the direction of the untreated alkali water entering the filter pipe 1 from the second pipe body 202 is upward, direct impact on the scale located at the bottom of the filter pipe 1 is avoided, the scale is agitated, and the settlement and separation effect is ensured.
