Description

Technical Field

[0001] This invention belongs to the field of water treatment technology, specifically relating to a domestic water purification treatment device. Background Technology

[0002] Wastewater treatment is a crucial step in ensuring environmental sanitation and the sustainable use of water resources. Modern wastewater treatment systems typically involve multi-stage processes. First, physical units such as screens and grit chambers remove larger suspended solids and impurities from the water. The effluent still requires further treatment to degrade various organic pollutants and remove pathogenic microorganisms. During this process, the use of chemical or biochemical agents (such as chlorine agents, ozone, and specific microbial agents) to react with residual fine particles, colloids, and pathogenic microorganisms in the water is a key step in achieving water purification. The effectiveness of this method directly determines the safety of the final effluent.

[0003] Currently, the dosing of the aforementioned chemicals generally relies on devices based on fixed dosing rates or manual adjustments based on operator experience. This control method has significant drawbacks: First, wastewater flow often fluctuates or even changes abruptly during actual operation. A fixed dosing rate cannot respond to dynamic changes in water flow in real time, resulting in insufficient chemical dosage and incomplete reaction when the influent flow suddenly increases, leading to a decrease in microbial removal efficiency and the potential for substandard effluent quality. Second, when the influent flow suddenly decreases, a fixed dosing rate can lead to excessive chemical dosage, wasting chemical resources, increasing operating costs, and potentially causing secondary pollution due to excessive residual chemicals. Therefore, we propose a domestic water purification treatment device to address these problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing wastewater treatment agents are mostly added at fixed rates or manually, which cannot respond in real time to dynamic changes in water flow, resulting in treatment delays when the flow suddenly increases and waste of agents when the flow suddenly decreases.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A domestic water purification treatment device includes a treatment tank, an inlet pipe fixedly installed on the side wall of the treatment tank near the upper end, a filter mechanism installed inside the treatment tank, a discharge valve for discharging sediment at the lower end of the treatment tank, water that has undergone preliminary filtration connected to the end of the inlet pipe, a fixed base fixedly installed on the treatment tank, a storage tank for holding flocculant fixedly installed on the fixed base, and a dispensing mechanism inside the inlet pipe for discharging flocculant from the storage tank according to the inlet water flow rate.

[0007] Further defining the dispensing mechanism, it includes a connecting tube, a movable plug movably installed inside the connecting tube, an L-shaped lever fixedly connected at one end to the movable plug, a tension spring fixedly installed between the L-shaped lever and the water inlet pipe, and an elastic sleeve fixedly installed between the L-shaped lever and the outer wall of the water inlet pipe. The connecting tube has an opening for the L-shaped lever to move, and an elastic membrane is fixedly installed between the inner wall of the opening and the L-shaped lever. The movable plug has multiple protrusions fixedly installed, and multiple through holes offset from the protrusions are opened on the movable plug. The water inlet pipe has multiple through holes adapted to the multiple protrusions. A sealing gasket is provided on the side of the movable plug near the water inlet pipe. The end of the L-shaped lever away from the movable plug extends into the water inlet pipe. A drive assembly is provided inside the water inlet pipe that can move the L-shaped lever under the impact of water flow. With this structural design, when water flows into the inlet pipe, the L-shaped lever will push the movable plug away from the through hole, so that the medicine in the storage tank flows into the treatment tank along with the water flow. The appropriate amount of medicine can be automatically sent into the treatment tank according to the water volume.

[0008] Further specifying, the drive assembly includes a rotating shaft, a fixed wheel fixedly mounted in the middle of the rotating shaft, several blades fixedly mounted on the fixed wheel, and a wedge-shaped top block fixedly mounted on the rotating shaft and adapted to the end of the L-shaped lever. The rotating shaft is rotatably mounted inside the water inlet pipe. With this structural design, when the blades and fixed wheel rotate under the impact of water flow, the wedge-shaped top block can push the L-shaped lever to move.

[0009] Furthermore, an inclined baffle is fixedly installed on the inner wall of the water inlet pipe, covering multiple through holes. The opening direction of the inclined baffle is opposite to the water inlet direction. This structural design reduces the pressure of the water flowing in the water inlet pipe on the protruding post and movable plug at the end of the through hole. Also, when water flows in the water inlet pipe, the flow velocity on the side of the inclined baffle closer to the through hole is lower than on the other side, facilitating the removal of the medicine.

[0010] Further specifying, the inlet pipe is a bent pipe with a bending angle greater than 90 degrees. A triangular prism-shaped water receiving box is rotatably installed inside the inlet pipe at the bend. A torsion spring is provided at the junction of the water receiving box and the inner wall of the inlet pipe. Under the action of the torsion spring, the water receiving box is pressed tightly against one side of the inner wall of the inlet pipe. When the water receiving box is full of water, it rotates towards the other side of the inner wall of the inlet pipe under the action of gravity. This structural design allows the water receiving box to quantitatively deliver water into the inlet pipe when the water flow rate at the inlet is small, thus effectively impacting the blades and the fixed wheel.

[0011] Further defining the filtration mechanism, it includes a filter plate movably mounted inside the treatment chamber, a fixing rod fixedly mounted on the filter plate, a fixing strip fixedly mounted on the upper end of the fixing rod, a motor fixedly mounted on the treatment chamber, and a threaded rod fixedly mounted on the motor output shaft. The upper end of the fixing rod passes through the upper end of the treatment chamber. The fixing strip is threadedly connected to the threaded rod. A fixing column is fixedly mounted on the treatment chamber, and the upper end of the fixing column is rotatably connected to the upper end of the threaded rod. A water pump is fixedly mounted on the treatment chamber, and a hose is fixedly mounted at the inlet end of the water pump. An inlet head is fixedly mounted at the end of the hose, and the inlet head has multiple inlets. The inlet head is fixedly mounted at the center of the filter plate. With this structural design, when the motor is working, the output shaft drives the threaded rod to rotate, which causes the fixing strip and fixing rod to push the filter plate downward, thereby separating the water and sediment in the treatment chamber.

[0012] Further specifying, a mounting rod is fixedly installed on the fixing strip, and a photoelectric switch transmitter is installed at the lower end of the mounting rod. Two symmetrical strip-shaped openings are formed on the processing box, each containing a piece of transparent glass. A photoelectric switch receiver is fixedly installed on the processing box at a position symmetrical to the photoelectric switch transmitter. The photoelectric switch transmitter, the two strip-shaped openings, and the photoelectric switch receiver are all located in the same plane. This structural design, with the photoelectric switch transmitter and receiver working together, allows for the determination of the boundary between sediment and water, facilitating the pushing of the filter plate to the appropriate position.

[0013] Further specifying, a mounting post is fixedly installed at the lower center of the filter plate, a limiting plate is fixedly installed at the lower end of the mounting post, a movable baffle is movably installed on the mounting post, a movable seal is provided between the movable baffle and the mounting post, a limiting rod is fixedly installed on the filter plate, an insertion hole adapted to the limiting rod is opened on the movable baffle, a drain outlet offset from the filter holes on the filter plate is opened on the movable baffle, a sealing gasket is provided at the upper end of the movable baffle, a compression spring is fixedly installed on the mounting post between the movable baffle and the limiting plate, and an electromagnet and a magnetic block are respectively provided on the movable baffle and the limiting plate. When the electromagnet is working, the electromagnet and the magnetic block are attracted by magnetism. This structural design, through the electromagnet and the magnetic block, facilitates the adjustment of the blocking or conducting state between the movable baffle and the filter plate.

[0014] Furthermore, an elastic folding cylinder is fixedly installed between the limiting plate and the movable baffle, and the elastic folding cylinder houses the compression spring, electromagnet, and magnetic block. This structural design prevents water from entering and damaging the compression spring, electromagnet, and magnetic block.

[0015] Furthermore, the water pump has a first fixed pipe fixedly installed at its outlet end, a secondary processing mechanism is provided at the end of the first fixed pipe, and a second fixed pipe is fixedly installed at the output end of the secondary processing mechanism. This structural design is simple and easy to use.

[0016] The invention employing the above technical solution has the following advantages:

[0017] 1. In this invention, when the water flow in the inlet pipe impacts the blades, the fixed wheel rotates, and the wedge-shaped top block on the rotating shaft will reciprocate to push the L-shaped lever. With the cooperation of the tension spring, the movable plug moves away from or towards the through hole. When the movable plug moves away from the through hole, the medicine in the storage tank can flow into the treatment tank along with the water flow. The appropriate amount of medicine can be automatically sent into the treatment tank according to the water volume.

[0018] 2. In this invention, when the water flow at the inlet of the water pipe is small, the water receiving box will collect the water. The water receiving box, when full of water, will rotate towards the inner wall of the other side of the water inlet under the action of gravity, so as to deliver the water in a metered manner into the water inlet, so as to ensure that the blades and the fixed wheel are effectively impacted, thereby successfully completing the dosing work.

[0048] like Figures 1-10 As shown, a domestic water purification treatment device of the present invention includes a treatment tank 1, an inlet pipe 2 fixedly installed on the side wall of the treatment tank 1 near the upper end, a filter mechanism 3 disposed in the treatment tank 1, a discharge valve for discharging sediment at the lower end of the treatment tank 1, water that has undergone preliminary filtration being connected to the end of the inlet pipe 2, a fixed base fixedly installed on the treatment tank 1, a storage tank 4 for holding flocculant fixedly installed on the fixed base, and a dispensing mechanism for discharging flocculant from the storage tank 4 into the inlet pipe 2 according to the inlet water flow rate.

[0049] The dispensing mechanism includes a connecting pipe 5, a movable plug 51 movably installed inside the connecting pipe 5, an L-shaped lever 52 fixedly connected to the movable plug 51 at one end, a tension spring 53 fixedly installed between the L-shaped lever 52 and the water inlet pipe 2, and an elastic sleeve 54 fixedly installed between the L-shaped lever 52 and the outer wall of the water inlet pipe 2. The connecting pipe 5 has an opening for the L-shaped lever 52 to move. An elastic membrane 521 is fixedly installed between the inner wall of the opening and the L-shaped lever 52. Multiple protrusions 511 are fixedly installed on the movable plug 51. Multiple through holes 512 that are offset from the protrusions 511 are opened on the movable plug 51. Multiple through holes 21 that are adapted to the multiple protrusions 511 are opened on the water inlet pipe 2. A sealing gasket is provided on the side of the movable plug 51 near the water inlet pipe 2. The end of the L-shaped lever 52 away from the movable plug 51 extends into the water inlet pipe 2. A drive assembly is provided inside the water inlet pipe 2 that can move the L-shaped lever 52 under the impact of water flow.

[0050] The drive assembly includes a rotating shaft 55, a fixed wheel 551 fixedly installed in the middle of the rotating shaft 55, several blades 552 fixedly installed on the fixed wheel 551, and a wedge-shaped top block 553 fixedly installed on the rotating shaft 55 and adapted to the end of the L-shaped lever 52. The rotating shaft 55 is rotatably installed inside the water inlet pipe 2.

[0051] An inclined baffle 22 is fixedly installed on the inner wall of the water inlet pipe 2. The inclined baffle 22 covers multiple through holes 21. The opening direction of the inclined baffle 22 is opposite to the water inlet direction. An arc-shaped baffle is also fixedly installed on the inner wall of the water inlet pipe 2. The arc-shaped baffle is located above the fixed wheel 551 and close to the water inlet direction of the water inlet pipe 2. This ensures that when water of different flow rates flows through the water inlet pipe 2, the rotation direction of the fixed wheel 551 is always consistent. When water flows through the water inlet pipe 2, the inclined baffle 22 guides the water flow. The flow velocity of the water between the inclined baffle 22 and the wall of the water inlet pipe 2 will be less than the flow velocity of the water in the water inlet pipe 2, so that the medicine at the through hole 21 can be smoothly carried out.

[0052] The inlet pipe 2 is a bent pipe with a bending angle greater than 90 degrees. Inside the inlet pipe 2, a triangular prism-shaped water receiving box 23 is rotatably installed at the bend. A torsion spring is provided at the junction of the water receiving box 23 and the inner wall of the inlet pipe 2. Under the action of the torsion spring, the water receiving box 23 is pressed tightly against one side of the inner wall of the inlet pipe 2. When the water receiving box 23 is full of water, the water receiving box 23 rotates on the other side of the inner wall of the inlet pipe 2 under the action of gravity.

[0053] The filtration mechanism 3 includes a filter plate 31 movably installed inside the treatment box 1, a fixing rod 32 fixedly installed on the filter plate 31, a fixing strip 33 fixedly installed on the upper end of the fixing rod 32, a motor 34 fixedly installed on the treatment box 1, and a threaded rod 35 fixedly installed on the output shaft of the motor 34. The upper end of the fixing rod 32 passes through the upper end of the treatment box 1. The fixing strip 33 is threadedly connected to the threaded rod 35. A fixing column is fixedly installed on the treatment box 1. The upper end of the fixing column is rotatably connected to the upper end of the threaded rod 35. A water pump 6 is fixedly installed on the treatment box 1. A hose 61 is fixedly installed at the water inlet end of the water pump 6. A water inlet head 62 is fixedly installed at the end of the hose 61. The water inlet head 62 has multiple water inlets. The water inlet head 62 is fixedly installed at the center of the filter plate 31.

[0054] A mounting rod 331 is fixedly installed on the fixing strip 33. A photoelectric switch transmitter 332 is installed at the lower end of the mounting rod 331. Two strip-shaped openings are symmetrically opened on the processing box 1. Transparent glass is embedded in each of the two strip-shaped openings. A photoelectric switch receiver 333 is fixedly installed on the processing box 1 at a position symmetrical to the photoelectric switch transmitter 332. The photoelectric switch transmitter 332, the two strip-shaped openings and the photoelectric switch receiver 333 are located in the same plane. When the photoelectric switch receiver 333 receives a light signal, the circuit between the motor 34 and the external power supply is in a conductive state. When the photoelectric switch receiver 333 loses a light signal, the motor 34 stops working.

[0055] A mounting post 311 is fixedly installed at the lower center of the filter plate 31. A limiting plate 312 is fixedly installed at the lower end of the mounting post 311. A movable baffle 313 is movably installed on the mounting post 311. A movable seal is provided between the movable baffle 313 and the mounting post 311. A limiting rod is fixedly installed on the filter plate 31. An insertion hole adapted to the limiting rod is opened on the movable baffle 313. A water leakage port offset from the filter holes on the filter plate 31 is opened on the movable baffle 313. A sealing gasket is provided at the upper end of the movable baffle 313. A compression spring 314 is fixedly installed between the movable baffle 313 and the limiting plate 312 on 311. An electromagnet 315 and a magnetic block 316 are respectively provided on the movable baffle 313 and the limiting plate 312. When the electromagnet 315 works, the electromagnet 315 and the magnetic block 316 are attracted by magnetism. When the filter plate 31 is located at the top of the treatment box 1, the movable baffle 313 is in close contact with the filter plate 31, which can ensure that the filter plate 31 does not come into contact with the water and medicine below, and can prevent the medicine from flowing upward from the filter plate 31, which would affect the treatment effect.

[0056] An elastic folding cylinder 317 is fixedly installed between the limit plate 312 and the movable baffle 313. The elastic folding cylinder 317 encloses the compression spring 314, electromagnet 315 and magnetic block 316. The photoelectric switch transmitter 332, photoelectric switch receiver 333, motor 34, electromagnet 315 and water pump 6 are connected to a compatible controller and an external power supply and are controlled by the controller.

[0057] A first fixed pipe 63 is fixedly installed at the outlet end of the water pump 6. A secondary treatment mechanism is installed at the end of the first fixed pipe 63. A second fixed pipe 64 is fixedly installed at the output end of the secondary treatment mechanism. The secondary treatment mechanism can use nuclear magnetic resonance polarization treatment technology or mineral regeneration technology as needed. Nuclear magnetic resonance polarization treatment technology: Through the synergistic effect of low-frequency weak magnetic field and specific frequency nuclear magnetic resonance wave, the hydrogen bond network between water molecules is broken, inducing them to self-assemble into stable small molecular clusters with an average particle size ≤5 nm. The coupling effect of local electric field and magnetic field generated by nuclear magnetic resonance polarization is used to inhibit cluster recombination and achieve the long-term stability of small molecular structure under normal temperature and pressure. Mineral regeneration technology: Using an activated filter element, trace elements from rare mineral sources are integrated into the water to achieve water quality restoration.

[0058] The method of using this invention is as follows:

[0059] When in use, water that has undergone preliminary treatment (water with solid impurities filtered out) is added to the treatment tank 1 through the water inlet pipe 2. When the water flow is large, the water receiving box 23 will be filled with water and rotated until it is close to the wall of the water inlet pipe 2. Under the impact of the water flow, it will maintain a tight relationship with the wall of the water inlet pipe 2. At this time, the water will flow directly through the water receiving box 23 into the water inlet pipe 2. If the water flow is small, the water receiving box 23 will collect the water until it is full. At this time, the water receiving box 23 will tilt under the action of gravity and rotate towards the other side of the water inlet pipe 2, periodically and quantitatively inputting the water inside into the water inlet pipe 2.

[0060] When water flows in the water receiving box 23, it exerts a force on the blade 552, causing the fixed wheel 551 and the rotating shaft 55 to rotate. The wedge-shaped top block 53 pushes the L-shaped lever 52 to move, which can move the movable plug 51 away from the water inlet pipe 2, thereby releasing the blocking effect on the through hole 21. The flocculant in the storage tank 4 will enter the water inlet pipe 2 through the through hole 512 and the through hole 21. After the wedge-shaped top block 53 pushes the movable plug 51 open by the L-shaped lever 52, the movable plug 51 will return to its initial position under the elastic force of the tension spring 53. Therefore, the amount of flocculant dispensed at the through hole 21 is positively correlated with the water flow rate in the water inlet pipe 2, and an appropriate amount of flocculant can be automatically added according to the water flow rate.

[0061] After the water mixed with flocculant enters the treatment tank 1, the flocculant causes suspended particles or colloidal substances in the water to aggregate into flocs. After settling, the flocs settle and remain at the bottom of the treatment tank 1. At this time, the photoelectric switch transmitter 332 and the photoelectric switch receiver 333 are activated. When the photoelectric switch receiver 333 receives the light signal, it connects the circuit between the motor 34 and the electromagnet 315 and the power supply. The motor 34 drives the threaded rod 35 to rotate, causing the fixing strip 33 and the fixing rod 32 to move downward. The filter plate 31 moves downward and extends underwater. Before the filter plate 31 moves downward, the electromagnet 315 is activated, generating a magnetic attraction force on the magnet 316. The movable baffle 313 can be separated from the filter plate 31 to release the blocking effect on the filter plate 31, so that the filter plate 31 can move smoothly down until the photoelectric switch transmitter 332 reaches the boundary between the flocculent and the water. At this time, the photoelectric switch receiver 333 loses the light signal, the motor 34 and the electromagnet 315 stop working, the water pump 6 starts working, the filter plate 31 stops at the boundary, and the movable baffle 313 resumes the blocking effect on the filter plate 31 under the elastic force of the compression spring 314. The water pump 6 can pump the filtered water to the secondary treatment mechanism for further treatment, while the flocculent at the bottom of the treatment tank 1 can be discharged outward through the discharge valve at the bottom.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
