Description

Technical Field

[0001] This utility model belongs to the field of pure water machine technology, specifically a pure water machine with a wastewater recycling mechanism. Background Technology

[0002] A water purifier is a device that provides direct drinking water. It uses a booster pump and reverse osmosis to produce pure water, removing impurities such as insect eggs, rust, and sand from the water. However, the water purifier will produce wastewater during the process of producing pure water.

[0003] The utility model patent with publication number CN223311788U discloses a pure water machine with a wastewater recycling mechanism. It solves the problem that existing pure water machines with wastewater recycling functions directly filter the wastewater produced by the machine, increasing the frequency of filter replacement and reducing filter lifespan. By setting up a sedimentation tank, the wastewater produced by the pure water machine is purified by sedimentation, allowing impurities such as silt to settle at the bottom, preventing them from being adsorbed by the water filter and causing clogging, thus increasing the maintenance frequency of the water filter. The water filter also filters and purifies floating matter inside the sedimentation tank. The filtered water is then pumped into the inlet pipe for reuse. However, in actual use, this patent has two drawbacks: firstly, the natural sedimentation efficiency of the wastewater is low, resulting in low wastewater recycling efficiency; secondly, it only discharges the sediment through a drain pipe, and since the sediment is mostly solid, it is prone to clogging and failure to discharge wastewater. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a pure water machine with a wastewater recycling mechanism, which has the advantages of being easy to use and having good recycling effect.

[0005] This utility model provides the following technical solution: a pure water machine with a wastewater recycling mechanism, comprising a pure water machine body, a sedimentation tank fixedly installed on the front of the pure water machine body, a filtration mechanism inside the sedimentation tank, a discharge mechanism at the bottom inside the sedimentation tank, and an accelerated sedimentation mechanism inside the sedimentation tank. An inlet pipe and a drain pipe are respectively connected to the front of the pure water machine body. The end of the drain pipe away from the pure water machine body is connected to the sedimentation tank. Wastewater discharged from the drain pipe is stored in the sedimentation tank, where it settles. The filtration mechanism can filter the wastewater, the discharge mechanism facilitates the discharge of solid impurities at the bottom inside the sedimentation tank, and the accelerated sedimentation mechanism can increase the sedimentation speed of impurities in the wastewater.

[0006] The beneficial effects of this utility model are as follows:

[0007] 1. This utility model uses a sedimentation tank to store and settle wastewater, combined with a filtration mechanism to filter the wastewater, a discharge mechanism to remove solid impurities, and an accelerated settling mechanism to increase the sedimentation speed. The synergistic effect of multiple mechanisms effectively solves the problem of low wastewater recycling efficiency in traditional pure water machines, thus realizing the recycling of wastewater and reducing water waste.

[0008] 2. This utility model uses filter holes in the filter cartridge of the filtration mechanism to intercept impurities. The water pump sends the filtered water back to the inlet pipe through the delivery hose for reuse. This not only avoids the problem of excessive burden on the filter element caused by impurities directly entering the water purifier, but also realizes the secondary utilization of water resources.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1 to 6As shown, the water purifier in this embodiment includes a main body 1. A sedimentation tank 2 is fixedly installed on the front of the main body 1. A filtration mechanism is installed inside the sedimentation tank 2. A discharge mechanism is installed at the bottom inside the sedimentation tank 2. An accelerated sedimentation mechanism is installed inside the sedimentation tank 2. An inlet pipe 10 and a drain pipe 11 are connected to the front of the main body 1. The end of the drain pipe 11 away from the main body 1 is connected to the sedimentation tank 2. The wastewater discharged from the drain pipe 11 is stored in the sedimentation tank 2. The wastewater settles in the sedimentation tank 2. The filtration mechanism can filter the wastewater. The discharge mechanism facilitates the discharge of solid impurities at the bottom inside the sedimentation tank 2. The accelerated sedimentation mechanism can improve the sedimentation speed of impurities in the wastewater. A temperature detector is installed inside the sedimentation tank 2 to detect the temperature inside the sedimentation tank 2 in real time, so that the temperature of the wastewater in the sedimentation tank 2 is at a suitable temperature, thereby improving the wastewater sedimentation efficiency. A controller is installed outside the device to control the various components in the device. The starting and stopping of the electrical appliances, the main body 1 of the above-mentioned pure water machine is similar in principle to the pure water machine with wastewater recycling mechanism disclosed in the utility model patent with publication number: CN223311788U, and achieves the same effect. This application will not elaborate further. The standard parts used in this utility model can all be purchased from the market.

[0018] refer to Figure 2 The top of the sedimentation tank 2 is fixedly connected to a sealing cover plate 3 by bolts. The filtration mechanism includes an upper round cover 4 fixedly connected to the top of the sealing cover plate 3 by screws. A lower round cover 5 is provided below the upper round cover 4. The lower round cover 5 is located inside the sedimentation tank 2. A filter cylinder 6 is fixedly connected between the upper round cover 4 and the lower round cover 5. A water pump 7 is fixedly connected to the top of the upper round cover 4. The bottom of the water pump 7 is connected to an inlet hard pipe 8. The bottom of the inlet hard pipe 8 extends into the interior of the filter cylinder 6. The outlet of the water pump 7 is connected to a delivery hose 9. The end of the delivery hose 9 away from the water pump 7 is connected to the inlet pipe 10 through a detachable connector. Impurities cannot pass through the filter holes evenly distributed on the surface of the filter cylinder 6. The operator can start the water pump 7. The water that passes through the filter cylinder 6 is drawn out by the water pump 7 and then input into the inlet pipe 10 through the delivery hose 9, and then re-enter the main body 1 of the pure water machine.

[0019] In this embodiment, the filter cartridge 6 in the filtration mechanism uses filter holes to intercept impurities, and the water pump 7 sends the filtered water back to the inlet pipe 10 for reuse through the delivery hose 9. This not only avoids the problem of excessive burden on the filter element caused by impurities directly entering the water purifier, but also realizes the secondary utilization of water resources.

[0020] refer to Figure 2 The discharge mechanism includes a spiral conveyor 12 rotatably connected inside the sedimentation tank 2. A drain pipe 14 is connected to the right side of the sedimentation tank 2. A solenoid valve is installed inside the drain pipe 14. A motor 13 is fixedly connected to the left side of the sedimentation tank 2. The output end of the motor 13 is fixedly connected to the spiral conveyor 12. The sedimented impurities accumulate in the lower part of the sedimentation tank 2. The operator can start the motor 13 to drive the spiral conveyor 12 to rotate, and then open the solenoid valve to discharge the impurities in the lower part of the sedimentation tank 2.

[0021] In this embodiment, the motor 13 in the discharge mechanism drives the spiral conveyor 12 to rotate, which smoothly pushes the solid impurities at the bottom of the sedimentation tank 2 to the sewage pipe 14. Combined with the solenoid valve controlling the discharge, this effectively solves the problem of the traditional sewage pipe 14 being easily blocked by the accumulation of solid impurities. This structure allows for smoother and more thorough discharge of impurities, reduces the frequency and difficulty of manual cleaning, ensures the long-term stable operation of the sedimentation tank 2, and maintains the high efficiency of the wastewater recycling system.

[0022] refer to Figure 2 The accelerated sedimentation mechanism includes a movable plate 16 installed inside the sedimentation tank 2. The movable plate 16 is fitted to the inner wall of the sedimentation tank 2 on all four sides. An opening 17 is provided on the surface of the movable plate 16, and a filter plate 18 is fixedly connected inside the opening 17. An electric telescopic rod 19 is fixedly connected to the front of the main body 1 of the pure water machine via a detachable bracket. The output end of the electric telescopic rod 19 extends into the interior of the sedimentation tank 2 and is fixedly connected to the top of the filter plate 18. When wastewater is input into the sedimentation tank 2 by the drain pipe 11, the movable plate 16 is at its highest position. At this time, the height of the movable plate 16 is greater than the height of the inlet of the sedimentation tank 2. When no more wastewater is input into the sedimentation tank 2, the operator starts the electric telescopic rod 19 to extend, thereby driving the movable plate 16 and the filter plate 18 to move down. Water can pass through the filter plate 18, while large-volume impurities cannot pass through the filter plate 18. The downward movement of the filter plate 18 will press the large-volume impurities down to the bottom of the sedimentation tank 2, thereby improving the sedimentation efficiency of the wastewater.

[0023] In this embodiment, the accelerated settling mechanism allows the movable plate 16 and filter plate 18 to move downwards under the drive of the electric telescopic rod 19. The filter plate 18 can then press large impurities to the bottom of the settling tank 2, preventing them from floating and affecting the settling efficiency. Compared to natural settling, this structure significantly shortens the impurity settling time, increases wastewater treatment speed, makes the filtration and recycling process more efficient, enables faster wastewater recycling, and enhances the equipment's wastewater treatment capacity.

[0024] refer to Figure 2 The back of the inner wall of the sedimentation tank 2 is provided with a groove, and an electric heating plate 15 is fixedly connected inside the groove. The surface of the sedimentation tank 2 is provided with a heat insulation layer.

[0025] In this embodiment, the temperature inside the sedimentation tank 2 can be adjusted via an electric heating plate 15 on the inner wall. A suitable temperature promotes the sedimentation and separation of impurities in the wastewater, improving the sedimentation effect. Specifically, the principle is as follows: Firstly, increased temperature reduces water viscosity, decreasing the resistance encountered by impurity particles as they sink, making them more easily succumb to gravity and settle rapidly to the bottom of the sedimentation tank 2. Secondly, increased thermal motion of water molecules may weaken the adhesion between tiny impurity particles and water molecules, or promote the aggregation of some tiny particles into larger flocs, increasing particle volume and gravity, further accelerating their settling speed, thereby shortening the overall settling time of wastewater impurities. The surface insulation layer reduces heat loss, lowers energy consumption, and avoids safety hazards caused by excessively high surface temperatures. This design allows the equipment to maintain stable sedimentation efficiency under different ambient temperatures, enhancing its applicability and energy efficiency. (The insulation layer is not shown.)

[0026] refer to Figure 2 The sealing cover 3 is internally connected to a limiting rod 20 that slides up and down, and the bottom of the limiting rod 20 is fixedly connected to the top of the filter plate 18.

[0027] In this embodiment, the limiting rod 20 inside the sealing cover plate 3 is connected to the filter plate 18, which acts as a guide when the movable plate 16 and the filter plate 18 move up and down, preventing them from rubbing against or misaligning with the inner wall of the sedimentation tank 2 due to displacement, thus ensuring the stability of the accelerated sedimentation mechanism. The setting of the limiting rod 20 also reduces the stress on the electric telescopic rod 19, extends the service life of the drive components, and ensures the long-term efficient operation of the equipment.

[0028] refer to Figure 3 An opening 22 is provided at the center of the top of the movable plate 16. Multiple scraping strips 23 are fixedly connected to the inner wall of the opening 22 in a ring shape and evenly distributed. The scraping strips 23 are in contact with the surface of the filter cartridge 6. When the movable plate 16 moves up and down, the scraping strips 23 move up and down with the movable plate 16. The scraping strips 23 can scrape off the impurities adhering to the surface of the filter cartridge 6, thereby reducing the frequency of maintenance of the filter cartridge 6.

[0029] In this embodiment, the scraper strip 23 on the movable plate 16 is attached to the surface of the filter cartridge 6. When the movable plate 16 moves up and down, it can scrape off the impurities adhering to the surface of the filter cartridge 6, preventing the filter holes from clogging and maintaining the filtration efficiency of the filter cartridge 6. This reduces the frequency of manual cleaning of the filter cartridge 6, lowers maintenance costs, and ensures the continuous and stable operation of the filtration mechanism, ensuring that the filtered water quality meets the requirements for recycling and improving the practicality of the equipment.

[0030] refer to Figure 1The sedimentation tank 2 has a liquid level observation window 21 on the front.

[0031] In this embodiment, the liquid level observation window 21 on the front of the sedimentation tank 2 allows operators to intuitively monitor the wastewater level inside the tank, enabling them to promptly understand the wastewater storage volume and treatment progress. This prevents wastewater overflow due to excessively high levels or disruptions to the treatment process due to excessively low levels. This design enhances the ease of operation, allowing operators to adjust operating parameters promptly based on the liquid level, ensuring the orderly progress of the wastewater recycling process.

[0032] First, check the status of each component of the device, confirming that the connection between the main body 1 of the pure water machine and the sedimentation tank 2 is secure, the solenoid valve is in the closed state, the electric telescopic rod 19 is in the retracted position, the movable plate 16 is in the highest position and its height is higher than the water inlet of the sedimentation tank 2, and there are no breaks or leaks in the pipes. Then, start the main body 1 of the pure water machine. The wastewater generated by the main body 1 during operation is transported to the sedimentation tank 2 through the drain pipe 11. The operator can check the amount of wastewater stored in the tank in real time through the liquid level observation window 21 on the front of the sedimentation tank 2 to prevent wastewater from overflowing. When the sedimentation tank 2 is filled with sufficient wastewater and the water intake is stopped, the electric telescopic rod 19 is activated. The electric telescopic rod 19 extends and moves the movable plate 16 and the filter plate 18 downward together. The movable plate 16 is tightly fitted to the inner wall of the sedimentation tank 2. During the downward movement, the limiting rod 20 in the sealing cover plate 3 moves synchronously with the filter plate 18, which plays a guiding role to prevent the movable plate 16 from shifting. The filter plate 18 allows water to pass through but blocks large-volume impurities, pressing the large-volume impurities down to the bottom of the sedimentation tank 2 to accelerate sedimentation. At the same time, the scraping strip 23 in the opening 22 at the top of the movable plate 16 is in contact with the surface of the filter cylinder 6 and scrapes off the impurities adhering to the surface of the filter cylinder 6 as the movable plate 16 moves, reducing the maintenance frequency of the filter cylinder 6.

[0033] If the ambient temperature is low and affects the sedimentation efficiency, the electric heating plate 15 in the groove on the back of the inner wall of the sedimentation tank 2 can be activated to regulate the temperature inside the tank. The insulation layer reduces heat loss and maintains a stable temperature inside the tank, ensuring efficient sedimentation of impurities. After the impurities have settled sufficiently, the water pump 7 in the filtration mechanism is started. The water that has settled in the sedimentation tank 2 passes through the filter holes on the surface of the filter cylinder 6 and enters the interior of the filter cylinder 6. It is then drawn by the water pump 7 through the inlet hard pipe 8 and transported through the delivery hose 9 to the inlet pipe 10 of the pure water machine body 1, where it re-enters the pure water machine body 1 to achieve wastewater recycling. When a large amount of solid impurities accumulate at the bottom of the sedimentation tank 2, the motor 13 in the discharge mechanism is started. The output end of the motor 13 drives the screw conveyor 12 to rotate inside the sedimentation tank 2. At the same time, the solenoid valve in the drain pipe 14 is opened. The screw conveyor 12 smoothly pushes the solid impurities to the drain pipe 14. The impurities are discharged from the sedimentation tank 2 through the drain pipe 14. After the discharge is completed, the motor 13 and the solenoid valve are turned off. This completes a complete wastewater recycling and impurity cleaning process. The above operation can be repeated to continuously achieve wastewater recycling and reuse, depending on the operation of the pure water machine and the liquid level observation window 21.
