Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a deep well water iron removal device for dialysis water equipment. Background Art

[0002] Iron and manganese are major components of the Earth's crust and are widely present in nature. Due to the filtering effect of strata on groundwater, iron and manganese in groundwater often exist as divalent iron and divalent manganese. These metal ions gradually oxidize into high-valent precipitates during contact with air, affecting water quality. Furthermore, if iron and manganese levels in groundwater exceed standards, their use as domestic water will affect sensory properties such as color, taste, and smell. When used as industrial water, they can negatively impact production in industries such as papermaking, chemical engineering, and printing and dyeing.

[0003] Existing research suggests that the yellowish color and fishy odor of deep well water stems from excessive levels of divalent iron (Fe) ions in the water. This is because unoxidized Fe ions are colorless and only oxidize to Fe ions after exposure to air, causing the water to turn yellow. Therefore, to reduce the adverse effects of Fe ions on water quality, both in production and daily life, and to achieve purifying the effluent, a deironing device suitable for deep well water is needed. Summary of the Invention

[0004] The utility model provides a deep well water iron removal device for dialysis water equipment, which achieves the purpose of reducing the yellowing of water by oxidizing divalent iron ions into trivalent iron ions in advance and causing precipitation.

[0014] Preferably, the deep well water iron removal device of the dialysis water equipment further comprises an air compressor, and the air outlet end of the air compressor is connected to the air inlet end of the first aeration component and the second aeration component respectively.

[0015] Preferably, the second aeration assembly includes a buffer sedimentation tank for accommodating the aeration tube group and a discharge port arranged at the bottom of the buffer sedimentation tank.

DETAILED DESCRIPTION

[0028] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] In order to achieve the above purpose, the embodiment of the present invention adopts the following technical solutions, referring to Figure 1The deep well water iron removal device of the dialysis water equipment includes an aeration mechanism, a filtering mechanism and an iron removal pool 30. Furthermore, the aeration mechanism includes a first aeration component 110 and a second aeration component. The first aeration component is connected to the deep well water source, and the first aeration component is used to mix the water and air and output it outward in a pressurized state. The second aeration component is arranged at the output end of the first aeration component, and an aeration pipe group 120 is provided inside the second aeration component. The filtering mechanism is a multi-stage filter arranged at the output end of the second aeration component. At the same time, the iron removal pool 30 is arranged at the output end of the multi-stage filter. When in use, the deep well water is aerated by the first aeration component and the second aeration component in sequence, and the divalent iron ions are oxidized into trivalent iron ions, and the trivalent iron ions are precipitated in the second aeration component. Then the water is transported to the multi-stage filter for re-filtration and precipitation, and finally the clarified water enters the iron removal pool. In this embodiment, the divalent iron ions are oxidized into trivalent iron ions and precipitated in advance to achieve the purpose of reducing the yellowing of the water.

[0030] Reference Figure 2 As a preferred technical solution of this embodiment, the first aeration assembly includes an air chamber 111, a nozzle 112, an air intake pipe 113, a mixing pipe 114, and a diffuser pipe 115. It should be noted that the air chamber 111 is provided with at least three openings. Specifically in this embodiment, the air chamber is provided with three openings, and the three openings can be respectively named as a first opening, a second opening, and a third opening. In this way, the nozzle 112 is arranged at the first opening of the air chamber, the air intake pipe 113 is arranged at the second opening of the nozzle, the mixing pipe 114 is arranged at the third opening of the air chamber, and the diffuser pipe 115 is arranged at the output end of the mixing pipe. When in use, water with a certain pressure is ejected at high speed through the nozzle, so that the high-speed pressure energy is converted into velocity energy, thereby forming a vacuum at the position of the air intake pipe. Compressed air is sucked into the air chamber and mixed with the water in the mixing pipe, and then discharged from the diffuser pipe, so that the water and compressed air are mixed to achieve the purpose of preliminary oxidation of iron ions. Then, the oxidized mixed gas and liquid can enter the next link.

[0031] Furthermore, the nozzle 112 has a nozzle body, and an indentation 1121 that is indented inwardly toward the nozzle axis is provided at one end of the nozzle 112 connected to the air chamber 111. In this way, the nozzle is designed to be wide in and narrow out, which can realize high-speed ejection of fluid through the nozzle.

[0032] Reference Figure 2As a preferred technical solution of this embodiment, the air chamber 111 includes a sudden expansion portion 1111, a straight expansion portion 1112 and a tapered portion 1113. It should be noted that the straight expansion portion 1112 is integrally formed with the sudden expansion portion, and the tapered portion 1113 is integrally formed with the straight expansion portion. In this way, the sudden expansion portion, the straight expansion portion and the tapered portion form a chamber structure with a conical cross-section. Specifically, in this embodiment, the first port is arranged at the position of the sudden expansion portion, the intake pipe is arranged at the position of the straight expansion portion, and the third port is arranged at the position of the tapered portion. In this way, after the working medium enters the air chamber through the nozzle, it can be mixed with the air in the above-mentioned chamber to obtain preliminary oxidation of the divalent iron ions.

[0033] Furthermore, the inner diameter of the diffuser 115 increases in a direction away from the mixing tube 114. The presence of the diffuser can increase the flow rate of the mixed water output from the air chamber so that the mixed gas and liquid can enter the next link.

[0034] Reference Figure 1 As a preferred technical solution of this embodiment, the deep well water iron removal device of the dialysis water equipment also includes an air compressor 40. The air compressor 40 includes two air outlet ends, and the two air outlet ends are respectively connected to the air inlet ends of the first aeration component and the second aeration component. The presence of the air compressor facilitates the delivery of compressed air to the first aeration component and the second aeration component, so that the air is mixed with the water body to achieve the reaction of divalent iron ions in the deep well water.

[0035] In addition, a gas solenoid valve is installed at the air compressor outlet. When deep well water enters the first aeration assembly, a pressure sensor detects the pressure and the air compressor gas solenoid valve opens for aeration. Aeration stops when there is no pressure. If the water treatment effect is not obvious, the aeration time can be adjusted by delaying the closing of the gas solenoid valve to increase the aeration time.

[0036] Further, refer to Figure 3 The second aeration assembly includes a buffer sedimentation tank 131, which serves as the main structure of secondary aeration and is used to accommodate the aeration tube group 120. At the same time, a discharge port 132 is provided at the bottom of the buffer sedimentation tank 131. Specifically, the aeration tube group 120 includes a main aeration pipe 121 and a plurality of aeration plates 122 arranged on the top of the main aeration pipe. When in use, the compressed air output by the air compressor enters the main aeration pipe and is discharged into the buffer sedimentation tank through the aeration plate. The compressed air contacts and merges with the water in the buffer sedimentation tank, thereby achieving the effect of secondary aeration to oxidize the iron ions in the water again.

[0037] It should be noted that the discharge port 132 can be opened automatically when needed to achieve the purpose of automatically and regularly discharging the precipitated sludge, thereby removing the trivalent iron ions obtained by oxidation.

[0038] Further, refer to Figure 4The aeration plate includes a bottom shell 1221 and an upper cover 1222. The bottom shell 1221 is connected to the main aeration pipe, and the upper cover 1222 is sealed and fastened on the top of the bottom shell. At the same time, a plurality of aeration holes 1223 are opened in the upper cover. In this way, the upper cover and the shell form a disc-shaped structure arranged on the main aeration pipe. When compressed air is applied to the inlet of the main aeration pipe, the air will flow out through the aeration holes on the aeration plate and contact the mixed gas and liquid in the buffer sedimentation tank to achieve the effect of secondary aeration. It should be noted that when installing the aeration plate, it is necessary to ensure that the aeration holes on the aeration plate are all installed upward to better integrate the water body.

[0039] As the preferred technical solution of this embodiment, the multi-stage filter includes a manganese sand filter 211 and a quartz sand filter 212. The manganese sand filter 211 is arranged at the output end of the buffer sedimentation tank 131, and the quartz sand filter 212 is arranged at the output end of the manganese sand filter. When in use, the manganese sand filter is used for pre-treatment to remove suspended matter and solid particles in the water. The quartz sand filter uses quartz sand as a filter medium. Under a certain pressure, water with high turbidity is filtered through granular or non-granular quartz sand of a certain thickness, effectively intercepting and removing suspended matter, organic matter, colloid particles, microorganisms, chlorine, odor and some heavy metal ions in the water, thereby ultimately achieving the effect of reducing water turbidity and purifying water quality.

[0040] Furthermore, the deep well water iron removal device of the dialysis water equipment also includes a booster pump 50 arranged between the buffer sedimentation tank 131 and the manganese sand filter 211. The water body aerated by the second aeration component can be transported to the manganese sand filter for filtration treatment under the pressure boosting action of the booster pump.

[0041] During use, deep well water is transported to the first aeration assembly 110, and a fluid with a certain pressure is ejected at high speed through the nozzle 112, so that the high-speed pressure energy is converted into velocity energy, thereby forming a vacuum at the position of the suction pipe 113, so that compressed air is sucked into the air chamber 111, mixed with the water in the mixing pipe 114, and discharged from the diffuser pipe 115. At this time, the water is mixed with the compressed air to achieve preliminary oxidation of the iron ions. The oxidized mixed gas and liquid enter the second aeration assembly. At this time, compressed air is applied to the inlet of the main aeration pipe 121. The air flows out through the aeration holes of the aeration plate 122, so that the compressed air contacts and merges with the water, thereby achieving the effect of secondary aeration and re-oxidation of the iron ions in the water. The water after secondary aeration and oxidation enters the manganese sand filter 211 and the quartz sand filter 212 respectively for filtration and precipitation. The purified water enters the iron removal tank 30. It should be noted that, in the present invention, the trivalent iron ions filtered out can be removed by regularly draining the buffer sedimentation tank 131 and cleaning the manganese sand filter and the quartz sand filter.

[0042] The above-described embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
