Description

Technical Field

[0001] This invention relates to the field of purification equipment, and in particular to a bio-flocculator and its purification device. Background Technology

[0002] Bioflocculants are special high-molecular-weight metabolites produced by microorganisms such as bacteria, molds, yeasts, and actinomycetes under specific conditions. They have the ability to coagulate and precipitate solid suspended particles that are not easily degraded in liquids.

[0003] Bioflocculants have advantages such as high efficiency, low cost, non-toxicity, and no secondary pollution, making them typical environmentally friendly functional materials.

[0004] Research on bioflocculants began in the 1950s, but it wasn't until the work of J. Nakamura et al. in 1976 that a real surge of interest in bioflocculant research was ignited. Following this, research on bioflocculants entered a comprehensive phase and yielded many important results. For example, in 1985, Takagi et al. developed the PF101 bioflocculant, and in 1986, Kurane et al. produced the protein-based flocculant NOC-1, which is considered to be the most effective bioflocculant discovered to date.

[0005] In existing technologies, wastewater purification requires the addition of bioflocculants in proportion to the amount of wastewater. This necessitates manual, continuous addition and monitoring, which is extremely time-consuming. Furthermore, the sludge remaining inside the container after purification is very difficult to clean. Therefore, we provide a bioflocculant and its purification device. Summary of the Invention

[0006] The present invention addresses the technical problem of how to control the amount of flocculant added during wastewater purification without directly using wastewater, so as to avoid reducing the accuracy of equipment detection, and how to enable the equipment to self-clean after wastewater purification. The invention provides a biological flocculant and its purification device.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a purification device, comprising: a sewage purification device, a quantitative flocculant dosing device, a cleaning device, a controller, and a support.

[0008] The support frame is installed on the ground. The wastewater purification device is installed inside the support frame and fixedly connected to its inner side. The metering flocculant dosing device is installed above the support frame and to the side of the wastewater purification device; it is connected to the top surface of the support frame and also to the wastewater purification device. The cleaning device is installed inside the wastewater purification device and connected to it. The controller is installed on the ground and to the side of the support frame; it is electrically connected to the wastewater purification device, the metering flocculant dosing device, and the cleaning device.

[0009] When a user wants to purify wastewater, they first activate the metered flocculant dosing device. Once activated, this device pressurizes the wastewater purification unit. The user then injects wastewater into the unit. As the liquid level rises, the liquid displaces any existing gas, which then flows back into the metered flocculant dosing device. This device then injects biological flocculant according to the rising liquid level. After a set time, the valve of the metered flocculant dosing device closes, stopping the injection of biological flocculant into the unit.

[0010] The reason for using air pressure to control the amount of bio-flocculator added to the wastewater treatment device, rather than directly using the rise in the wastewater level, is that due to the characteristics of the wastewater itself, it would contaminate the device inside the metering flocculant addition device, thereby reducing the accuracy of the control components of the metering flocculant addition device and increasing the service life of the equipment.

[0011] At this point, after the user starts the sewage purification device through the controller, the sewage purification device will continuously mix the biological flocculant with the sewage, thereby diluting the biological flocculant and accelerating the reaction with the sewage. After the stirring is completed and the sedimentation is finished, the user can then control the sewage purification device to discharge the purified sedimented sludge and liquid out of the sewage purification device, thereby collecting the sludge and the initially purified liquid.

[0012] After collection is complete, the user can again control the wastewater purification device to switch control modes via the controller, thereby activating the cleaning device and injecting cleaning liquid into the vessel to complete the cleaning function inside the vessel. This collects all the sludge, preventing it from emitting foul odors and affecting the surrounding environment and subsequent wastewater purification. This functional setup allows for the control of flocculant dosage based on the amount of wastewater used during wastewater purification, avoiding direct use of wastewater and preventing a decrease in equipment detection accuracy. Furthermore, the device can self-clean after wastewater purification.

[0013] Furthermore, the wastewater purification device includes: a drive motor, a stirring rod, spiral stirring blades, a vessel body, a water inlet pipe, and a solenoid valve.

[0014] The vessel body is installed inside the support and is fixedly connected to the inner wall of the support, and is connected to the quantitative flocculant feeding device.

[0015] The drive motor is located above the vessel body and at the top of the vessel body. The rotating shaft of the drive motor passes through the top of the vessel body and extends into the interior of the vessel body. The rotating shaft of the drive motor is rotatably connected to the top of the vessel body. The rotating axis is set vertically and connected to the cleaning device.

[0016] The stirring rod is vertically installed inside the vessel body, and the top of the stirring rod is fixedly connected to the rotating shaft of the drive motor.

[0017] The spiral stirring blades are respectively installed inside the vessel body and sleeved on the stirring rod, and the spiral stirring blades are fixedly connected to the side of the stirring rod.

[0018] The water inlet pipe is located on the side of the vessel body and below the drive motor. One end of the water inlet pipe passes through the side of the vessel body and is connected to the inside of the vessel body.

[0019] The solenoid valve is located below the vessel body and at the bottom of the vessel body. The solenoid valve is fixedly connected to the bottom of the vessel body and communicates with the interior of the vessel body. The solenoid valve is also electrically connected to the controller.

[0020] When the user starts the quantitative flocculant dosing device and completes the gas injection and pressurization of the vessel, when the user injects sewage into the vessel through the water inlet pipe, each time the sewage level rises, a corresponding volume of gas will enter the quantitative flocculant dosing device. This allows the quantitative flocculant dosing device to control the flow rate of the biological flocculant added into the vessel according to the rise in the liquid level. Since the valve control time of the quantitative flocculant dosing device is controlled within a certain time, controlling the flow rate within a certain time can control the amount of biological flocculant added. Once the bio-flocculator and wastewater are fully added to the reactor, the user can stop the quantitative flocculant device via the controller and start the drive motor. The rotating shaft of the drive motor drives the stirring rod, which in turn rotates the spiral agitator blades, accelerating the reaction and mixing of the wastewater and bio-flocculator, thus speeding up wastewater purification. After the set stirring time is reached, the user can stop the drive motor via the controller and wait for the wastewater to settle. Once settling is complete, the user can activate the solenoid valve via the controller to first discharge and collect the settled sludge from the reactor, then wait for further settling, and then collect the liquid for further settling or purification. This process completes the wastewater purification.

[0021] Furthermore, the quantitative flocculant addition device includes: a pressurized air pump, a vent pipe, a pure water tank, a buoyancy sensing tube, a float, a pull rope, a stop block, a tension spring, a flocculant delivery box, a delivery pipe, a third check valve, an electrically controlled air valve, a support plate, and a first check valve.

[0022] The support plate is horizontally positioned on the side of the vessel body and above the support frame. The bottom surface of the support plate is fixedly connected to the top surface of the support frame, and the side surface is in contact with the side surface of the vessel body.

[0023] The purified water tank is positioned above the support plate and to the side of the vessel body, with the bottom surface of the purified water tank fixedly connected to the top surface of the support plate.

[0024] The buoyancy sensing tube is closed at both ends and vertically installed above the support plate, on the side of the pure water tank near the vessel body. The bottom surface of the buoyancy sensing tube is fixedly connected to the top surface of the support plate and is connected to the interior of the pure water tank through a water pipe.

[0025] The flocculant delivery box is located above the buoyancy sensing tube and on the side of the vessel. The outer bottom surface of the flocculant delivery box is fixedly connected to the top surface of the buoyancy sensing tube and communicates with the interior of the buoyancy sensing tube. The interior of the flocculant delivery box is equipped with a horizontal partition, which divides the internal space into two parts.

[0026] The tension spring is vertically installed inside the flocculant delivery box, below the partition of the flocculant delivery box, with its bottom end facing the top end of the buoyancy sensing tube. The top end of the tension spring is fixedly connected to the bottom surface of the partition of the flocculant delivery box.

[0027] The baffle is vertically installed inside the flocculant delivery box and directly below the tension spring. The top surface of the baffle is fixedly connected to the bottom end of the tension spring.

[0028] The pull rope is vertically installed inside the buoyancy sensing tube, and its top end passes through the top surface of the buoyancy sensing tube and is connected to the bottom end of the tension spring.

[0029] The buoy is installed inside the buoyancy sensing tube and is fixedly connected to the bottom end of the pull rope.

[0030] The delivery pipe is a right-angle pipe and is located inside the flocculant delivery box, below the partition of the flocculant delivery box and to the side of the tension spring. One end of the delivery pipe is connected to the inside of the flocculant delivery box.

[0031] The first one-way valve is located inside the flocculant delivery box and below the partition of the flocculant delivery box. One end of the first one-way valve is connected to the other end of the delivery pipe, and the other end is completely blocked by the baffle.

[0032] The third check valve is located on the side of the flocculant delivery box, below the delivery pipe, and on the side away from the tension spring from the delivery pipe. The flocculant delivery box is connected to the interior of the vessel body through the third check valve.

[0033] The pressurized air pump is located on the side of the support away from the pure water tank, and the pressurized air pump is connected to the inside of the vessel through an air pipe.

[0034] The electrically controlled air valve is located on the side of the vessel body near the buoyancy sensing tube. The electrically controlled air valve is connected to the interior of the vessel body and is also connected to the interior of the pure water tank through a vent pipe.

[0035] When a user wants to purify wastewater, they should first start the pressurized air pump via the controller. Once started, the pump will fill the vessel with gas through the air pipe. After the vessel is full, the pressurized air pump can be stopped via the controller, and the electrically controlled air valve will open, as well as the first and third one-way valves, which will remain open for a certain period. When the user injects wastewater into the vessel, the liquid level rises, forcing excess air into the purified water tank through the electrically controlled air valve. The pressure inside the purified water tank gradually increases, causing the liquid to flow through the water pipe into the buoyancy sensor tube. As the liquid level rises, it exerts buoyancy on the float, reducing the tension on the spring via the rope and stop. This causes the spring to retract, allowing the stop to move upwards and open the first one-way valve. The higher the liquid level in the buoyancy sensing tube, the higher the float will be, resulting in a greater retraction of the tension spring. This reduces the obstruction of the first one-way valve by the baffle, thus controlling the amount of bio-flocculant that falls onto the bottom of the flocculant delivery tank through the delivery pipe and the first one-way valve. When the bio-flocculant falls onto the bottom of the flocculant delivery tank, it will enter the vessel through the third one-way valve. When the opening time of the first and third one-way valves is reached, the bio-flocculant is added to the vessel in proportion to the amount of wastewater, achieving precise addition and avoiding waste.

[0036] After the wastewater is purified and discharged from the vessel, the air that entered the pure water tank will return to the vessel through the electrically controlled air valve due to the freed-up space inside the vessel. This allows the liquid inside the buoyancy sensor tube to return to the pure water tank, causing the float and tension spring to return to their original positions and control the electrically controlled air valve to close, thus avoiding affecting the quantitative addition of the bio-flocculant in the next cycle.

[0037] Using air pressure to drive the liquid in the pure water tank to apply buoyancy to the float avoids the use of sewage to apply buoyancy to the float, which would cause the float to become covered with sludge, affecting its weight and increasing the amount of cleaning work.

[0038] Furthermore, the cleaning device includes: a rubber block, an electromagnetic slider, a curved sliding groove, a cleaning ring, several cleaning scrapers, an inner fixing ring, several outer ring connecting rods, several fixing springs, several fixing plates, and several enclosed protective sleeves.

[0039] The curved sliding groove is located inside the vessel body, on the surface of the stirring rod, and below several spiral stirring blades.

[0040] The electromagnetic slider is located inside the vessel body and within a curved sliding groove. The electromagnetic sliders are slidably connected to each other, and the sliding direction is rotation around the axial direction of the stirring rod. The electromagnetic slider is also electrically connected to the controller.

[0041] The rubber block is made of elastic material and is located inside the vessel body, on the outside of the stirring rod. The rubber block is fixedly connected to the outer side of the electromagnetic slider.

[0042] The inner fixing ring is inclinedly set inside the vessel body and sleeved on the outside of the stirring rod, located below the spiral stirring blades and above the solenoid valve. A groove is provided on the inner surface of the inner fixing ring, and the groove matches the expanded rubber block.

[0043] Several fixing springs are respectively installed inside the vessel body. Several fixing springs are respectively installed on the side of the inner fixing ring near the stirring rod. One end of each fixing spring is fixedly connected to the inner side of the inner fixing ring, and the other end is connected to the side of the stirring rod.

[0044] Several fixed plates are respectively arc-shaped plates and are respectively positioned between several fixed springs and stirring rods. The outer arc surfaces of several fixed plates are respectively fixedly connected to the other ends of several fixed springs, and the inner arc surfaces of the plates match the curvature of the outer side of the stirring rod and are in contact with the outer side of the stirring rod.

[0045] Several outer ring connecting rods are inclinedly arranged inside the vessel body and are located on the outside of the inner fixed ring. One end of each of the outer ring connecting rods is fixedly connected to the outer side of the inner fixed ring.

[0046] The cleaning ring is located inside the vessel body and outside several outer ring connecting rods. The center of the cleaning ring coincides with the center of the inner fixed ring, and the inner side of the cleaning ring is fixedly connected to the other end of several outer ring connecting rods.

[0047] Several cleaning scrapers are respectively installed inside the vessel body and are located on the outer side of the cleaning ring. The cleaning scrapers are fixedly connected to the outer side of the cleaning ring and are in contact with the inner side of the vessel body.

[0048] Several closed sheaths are respectively fitted onto the outside of several fixed springs and are respectively fixedly connected to the inner side of the inner fixed ring.

[0049] After the user discharges the purified wastewater from the vessel, the user can control the drive motor to switch control modes via the controller, causing the drive motor to switch to an alternating forward and reverse working mode, and inject cleaning agent into the vessel through the water inlet pipe. When the wastewater is discharged, the gas that entered the purified water tank returns to the vessel, increasing the internal pressure. As the internal pressure increases, the rubber block, made of elastic material, expands upon sensing the increased external pressure. This expansion causes the rubber block to embed itself into the groove on the inner side of the inner fixing ring, thus connecting the inner fixing ring. When the drive motor switches to alternating forward and reverse operation mode, the controller also controls the electromagnetic slider to close, allowing it to slide along the curved sliding groove. When the drive motor drives the stirring rod to rotate forward or reverse, the electromagnetic slider drives the rubber block to slide along the curved sliding groove. This, along with the inner fixed ring and several outer ring connecting rods, allows the cleaning ring to slide along the curved sliding groove while simultaneously rotating around the axis of the stirring rod. This causes the cleaning scrapers on the outer side of the cleaning ring to move up and down while rotating around the axis of the stirring rod, thus scraping the inner surface of the vessel. This removes the sludge adhering to the inner surface of the vessel. After cleaning, the user can reopen the solenoid valve, stop the drive motor, and activate the electromagnetic slider to discharge the cleaned wastewater from the vessel, preventing it from affecting the next wastewater purification cycle.

[0050] Furthermore, the quantitative flocculant dosing device also includes a pressure gauge. The pressure gauge is located on the outside of the vessel body and below the support. The measuring end of the pressure gauge penetrates through the side of the vessel body and is connected to the inside of the vessel body.

[0051] Users can use a pressure gauge to accurately determine whether the internal pressure of the vessel has reached the appropriate standard, and then choose whether to increase or decrease the pressure.

[0052] Furthermore, the wastewater purification device also includes an observation port. The observation port is located on the side of the vessel body, below the support, and to the side of the pressure gauge. The observation port is connected to the interior of the vessel body and has a glass plate installed inside.

[0053] Users can observe the degree of wastewater purification and cleanliness inside the vessel through the observation port, thereby observing the effect of wastewater sedimentation and the cleanliness of the vessel's interior.

[0054] Furthermore, the quantitative flocculant addition device also includes: a liquid level detector and a water filling pipe.

[0055] The liquid level detector is installed inside the pure water tank and is fixedly connected to the top surface inside the pure water tank. The liquid level detector is also electrically connected to the controller.

[0056] One end of the filling pipe passes through the top of the purified water tank and connects to the inside of the purified water tank, while the other end connects to the water supply pipe.

[0057] When the level detector detects that the liquid level inside the purified water tank has not reached the set level, the level detector can send the value to the controller. After the user checks the value, they can open the water supply pipe and replenish the liquid inside the purified water tank through the filling pipe.

[0058] Furthermore, the wastewater purification device also includes a temperature sensor and a heater. The temperature sensor is located on the outside of the vessel body and on the outside of the support frame. The probe of the temperature sensor penetrates the side of the vessel body and extends into the interior of the vessel body. The temperature sensor is fixedly connected to the side of the support frame and electrically connected to the controller.

[0059] The heater is located inside the vessel and is fixedly connected to the top surface inside the vessel. The heater is also electrically connected to the controller.

[0060] After the temperature sensor detects the temperature inside the vessel, it transmits the reading to the controller. The user can then determine whether the temperature inside the vessel has reached a suitable level based on the controller's reading, and choose whether to activate the heater through the controller to raise the temperature inside the vessel to achieve the appropriate reaction temperature for the bio-flocculator.

[0061] Furthermore, the wastewater purification device also includes: a feed pipe, a second check valve, and a pH sensor.

[0062] The pH sensor is located to the side of the temperature sensor and on the outside of the bracket. The pH sensor is fixedly connected to the outer side of the bracket, and its probe extends through the side of the vessel and into the interior of the vessel. The pH sensor is also electrically connected to the controller.

[0063] The second one-way valve is located above the vessel body and to the side of the drive motor. The second one-way valve is located at the top of the vessel body and is connected to the interior of the vessel body.

[0064] The feed pipe is vertically positioned directly above the second check valve, and its bottom end is connected to the inside of the second check valve.

[0065] The pH sensor can transmit the pH value of the wastewater inside the vessel to the controller. After the controller displays the reading, the user can determine whether it is necessary to open the second one-way valve through the controller to add relevant chemical reagents or more biological flocculants into the vessel through the feed pipe.

[0066] A bioflocculant using XR-205 bioflocculant.

[0067] The beneficial effects of this invention are:

[0068] 1. The invention utilizes the mutual cooperation and support between a wastewater purification device, a quantitative flocculant dosing device, a cleaning device, a controller, and a support frame. When the quantitative flocculant dosing device is activated by the user operating the controller, it fills the wastewater purification device with air. After this air filling, when the user activates the wastewater purification device again via the controller, the rising liquid level inside the device causes the injected air to re-enter the quantitative flocculant dosing device. This allows the device to precisely control the amount of biological flocculant added based on the liquid level within the wastewater purification device, thus automatically adding and proportioning the biological flocculant. After the biological flocculant is added, the user can activate the wastewater purification device again via the controller to accelerate the reaction and mixing of the wastewater and biological flocculant. Once the wastewater is purified and discharged from the wastewater purification device, the user can then activate the cleaning device via the controller to clean the interior of the wastewater purification device. This functional setup enables the control of flocculant dosage based on the amount of wastewater input during wastewater purification, while avoiding direct use of wastewater. This prevents a decrease in equipment detection accuracy and allows the equipment to self-clean after wastewater purification.

[0069] 2. Through the coordinated operation and mutual support of the pressurized air pump, vent pipe, pure water tank, buoyancy sensor, float, pull rope, stop block, tension spring, flocculant delivery box, delivery pipe, third check valve, electrically controlled air valve, support plate, and first check valve, buoyancy is achieved by using air pressure to drive the liquid in the pure water tank to apply buoyancy to the float. This design avoids using sewage to apply buoyancy to the float, which would cause the float to become covered with sludge, affecting its weight and increasing cleaning workload.

[0070] 3. By setting up a rubber block made of elastic material and an electromagnetic slider, the electromagnetic slider can only slide within the curved sliding groove when it is stopped by the controller. This ensures that the rubber block on the electromagnetic slider is always in the same position as the groove of the inner fixed ring. The elastic material of the rubber block allows it to embed into the groove of the inner fixed ring when the surrounding air pressure increases. When sewage is injected, the pressure provided by the sewage is insufficient, so the rubber block cannot embed into the inner fixed ring, thus avoiding the inner fixed ring driving the cleaning ring and affecting the flocculation efficiency of the bio-flocculator.

[0075] The following will describe the concept and technical effects of the present invention clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of the present invention.

[0076] Please see Figure 1-3 A purification device, comprising: a wastewater purification device, a quantitative flocculant dosing device, a cleaning device, a controller 1, and a support 2.

[0077] Support 2 is installed on the ground. The wastewater purification device is installed inside support 2 and fixedly connected to the inner side of support 2. The quantitative flocculant dosing device is installed above support 2 and to the side of the wastewater purification device. The quantitative flocculant dosing device is connected to the top surface of support 2 and to the wastewater purification device. The cleaning device is installed inside the wastewater purification device and connected to the wastewater purification device. Controller 1 is installed on the ground and to the side of support 2. Controller 1 is electrically connected to the wastewater purification device, the quantitative flocculant dosing device, and the cleaning device.

[0078] When a user wants to purify wastewater, the user first activates the quantitative flocculant dosing device using controller 1. Once activated, the device pressurizes the wastewater purification unit. The user then injects wastewater into the unit. As the liquid level rises, the liquid encroaches on the gas inside the unit, allowing it to re-enter the quantitative flocculant dosing device. The device then injects biological flocculant according to the rising liquid level. After a set time, the valve of the quantitative flocculant dosing device closes, stopping the injection of biological flocculant into the vessel 104.

[0079] The reason for using air pressure to control the amount of bio-flocculator added to the wastewater treatment device, rather than directly using the rise in the wastewater level, is that due to the characteristics of the wastewater itself, it would contaminate the device inside the metering flocculant addition device, thereby reducing the accuracy of the control components of the metering flocculant addition device and increasing the service life of the equipment.

[0080] At this point, after the user starts the sewage purification device through controller 1, the sewage purification device will continuously mix the biological flocculant with the sewage, thereby diluting the biological flocculant and accelerating the reaction with the sewage. After the stirring is completed and the sedimentation is complete, the user can control the sewage purification device to discharge the purified sedimented sludge and liquid out of the sewage purification device, thereby collecting the sludge and the initially purified liquid.

[0081] After collection is complete, the user can again control the wastewater purification device to switch control modes via controller 1, thereby activating the cleaning device and injecting cleaning liquid into the vessel 104 to complete the cleaning function inside the vessel 104. This collects all the sludge, preventing it from emitting foul odors and affecting the surrounding environment and subsequent wastewater purification. This functional setup achieves the technical effect of controlling the amount of flocculant added based on the amount of wastewater input during wastewater purification, avoiding direct use of wastewater, thus preventing a decrease in equipment detection accuracy, and enabling the equipment to self-clean after wastewater purification.

[0082] The wastewater purification device includes: a drive motor 101, a stirring rod 102, a spiral stirring blade 103, a vessel body 104, a water inlet pipe 105, and a solenoid valve 106.

[0083] The vessel body 104 is located inside the support 2 and is fixedly connected to the inner wall of the support 2, and is connected to the quantitative flocculant feeding device.

[0084] The drive motor 101 is located above the vessel body 104 and at the top of the vessel body 104. The rotation shaft of the drive motor 101 passes through the top of the vessel body 104 and extends into the interior of the vessel body 104. The rotation shaft of the drive motor 101 is rotatably connected to the top of the vessel body 104. The rotation axis is vertically arranged and connected to the cleaning device.

[0085] The stirring rod 102 is vertically arranged inside the vessel body 104, and the top end of the stirring rod 102 is fixedly connected to the rotating shaft of the drive motor 101.

[0086] Spiral stirring blades 103 are respectively disposed inside the vessel body 104 and sleeved on the stirring rod 102, and the spiral stirring blades 103 are fixedly connected to the side of the stirring rod 102.

[0087] The water inlet pipe 105 is located on the side of the vessel body 104 and below the drive motor 101. One end of the water inlet pipe 105 passes through the side of the vessel body 104 and communicates with the interior of the vessel body 104.

[0088] The solenoid valve 106 is located below the vessel body 104 and at the bottom of the vessel body 104. The solenoid valve 106 is fixedly connected to the bottom of the vessel body 104 and communicates with the interior of the vessel body 104. The solenoid valve 106 is also electrically connected to the controller 1.

[0089] When the user starts the quantitative flocculant dosing device and completes the gas injection and pressurization of the vessel 104, when the user injects sewage into the vessel 104 through the water inlet pipe 105, each time the sewage level rises, a corresponding volume of gas will enter the quantitative flocculant dosing device. This allows the quantitative flocculant device to control the flow rate of the biological flocculant added into the vessel 104 according to the rise in the liquid level. Since the valve control time of the quantitative flocculant device is controlled within a certain time, controlling the flow rate within a certain time can control the amount of biological flocculant added. When the bio-flocculator and wastewater are all added into the vessel 104, the user can stop the quantitative flocculant device via controller 1 and start the drive motor 101. Once the drive motor 101 starts, its rotating shaft drives the stirring rod 102, which in turn rotates the spiral agitator blades. This accelerates the reaction and mixing of the wastewater and bio-flocculator, thus speeding up wastewater purification. After the set stirring time is reached, the user can stop the drive motor 101 via controller 1 and wait for the wastewater to settle. Once settling is complete, the user can activate the solenoid valve 106 via controller 1 to first discharge and collect the settled sludge from the vessel 104, then wait for further settling, and then collect the liquid for further settling or purification. This completes the wastewater purification process.

[0090] The quantitative flocculant dosing device includes: a pressurized air pump 201, an air pipe 202, a pure water tank 203, a buoyancy sensing tube 204, a float 205, a pull rope 206, a stop block 207, a tension spring 208, a flocculant delivery box 209, a delivery pipe 210, a third check valve 211, an electrically controlled air valve 212, a support plate, and a first check valve 213.

[0091] The support plate is horizontally arranged on the side of the vessel body 104 and above the support 2. The bottom surface of the support plate is fixedly connected to the top surface of the support 2, and the side surface is in contact with the side surface of the vessel body 104.

The interior of the flocculant delivery box 209 is provided with a horizontal partition, which divides the internal space into two parts.

[0095] The tension spring 208 is vertically installed inside the flocculant delivery box 209 and is located below the partition of the flocculant delivery box 209. Its bottom end is directly opposite the top end of the buoyancy sensing tube 204. The top end of the tension spring 208 is fixedly connected to the bottom surface of the partition of the flocculant delivery box 209.

[0096] The stop block 207 is vertically installed inside the flocculant delivery box 209 and is located directly below the tension spring 208. The top surface of the stop block 207 is fixedly connected to the bottom end of the tension spring 208.

[0097] The pull rope 206 is vertically installed inside the buoyancy sensing tube 204, and its top end passes through the top surface of the buoyancy sensing tube 204 and is connected to the bottom end of the tension spring 208.

[0098] The float 205 is installed inside the buoyancy sensing tube 204 and is fixedly connected to the bottom end of the pull rope 206.

[0099] The delivery pipe 210 is a right-angle pipe and is located inside the flocculant delivery box 209, below the partition of the flocculant delivery box 209 and to the side of the tension spring 208. One end of the delivery pipe 210 is connected to the inside of the flocculant delivery box 209.

[0100] The first one-way valve 213 is located inside the flocculant delivery box 209 and below the partition of the flocculant delivery box 209. One end of the first one-way valve 213 is connected to the other end of the delivery pipe 210, and the other end is completely blocked by the stop block 207.

[0101] The third check valve 211 is located on the side of the flocculant delivery box 209, below the delivery pipe 210, and on the side away from the tension spring 208. The flocculant delivery box 209 is connected to the interior of the vessel body 104 through the third check valve 211.

[0102] The pressurized air pump 201 is located on the side of the bracket 2 away from the pure water tank 203, and the pressurized air pump 201 is connected to the interior of the vessel body 104 through an air pipe.

[0103] The electrically controlled air valve 212 is located on the side of the vessel body 104 near the buoyancy sensing tube 204. The electrically controlled air valve 212 is connected to the interior of the vessel body 104 and is connected to the interior of the pure water tank 203 through the air pipe 202.

[0104] When a user wants to purify wastewater, the user should first start the pressurized air pump 201 via controller 1. After the pressurized air pump 201 starts, it will fill the vessel 104 with gas through the air pipe. Once the vessel 104 is full of gas, the user can stop the pressurized air pump 201 via controller 1, open the electrically controlled air valve 212, and control the first one-way valve 213 and the third one-way valve 211 to open for a certain period of time. When the user injects wastewater into the vessel 104, the liquid level inside the vessel 104 rises as the wastewater enters. The liquid will then push excess air into the purified water tank 203 through the electrically controlled air valve 212. At this time, the air pressure inside the pure water tank 203 will gradually increase, causing the liquid inside the pure water tank 203 to enter the buoyancy sensing tube 204 through the water pipe. As the liquid level inside the buoyancy sensing tube 204 gradually rises, the liquid level will exert buoyancy on the float 205, thereby reducing the tension of the float 205 on the tension spring 208 through the pull rope 206 and the stop block 207. This causes the tension spring 208 to retract, allowing the stop block 207 to move upward and open the obstruction of the first one-way valve 213. The higher the liquid level in the buoyancy sensing tube 204, the higher the position of the float 205 will be, resulting in a greater retraction of the tension spring 208. This reduces the obstruction of the stop block 207 on the first one-way valve 213, thereby controlling the amount of bio-flocculant inside the flocculant delivery tank 209 that falls onto the bottom surface of the flocculant delivery tank 209 through the delivery pipe 210 and the first one-way valve 213. When the bio-flocculant falls onto the bottom of the flocculant delivery box 209, it enters the vessel 104 through the third one-way valve 211. When the opening time of the first one-way valve 213 and the third one-way valve 211 is reached, the bio-flocculant that matches the amount of sewage is added into the vessel 104, achieving precise addition of the bio-flocculant and avoiding waste.

[0105] After the wastewater is purified and discharged from the vessel 104, the air that entered the pure water tank 203 will return to the vessel 104 through the electrically controlled air valve 212 due to the freed-up space inside the vessel 104. This allows the liquid inside the buoyancy sensor tube 204 to return to the pure water tank 203, causing the float 205 and tension spring 208 to return to their original positions and control the electrically controlled air valve 212 to close, thus avoiding affecting the quantitative addition of the bio-flocculator in the next cycle.

[0106] By using air pressure to drive the liquid in the pure water tank 203 to apply buoyancy to the float 205, the design avoids using sewage to apply buoyancy to the float 205, which would cause the float 205 to be covered with sludge, affecting the weight of the float 205 and increasing the amount of cleaning work.

[0107] The cleaning device includes: a rubber block, an electromagnetic slider, a curved sliding groove 301, a cleaning ring 302, several cleaning scrapers, an inner fixing ring 303, several outer ring connecting rods 304, several fixing springs, several fixing plates, and several enclosed protective sleeves.

[0108] The curved sliding groove 301 is disposed inside the vessel body 104 and on the surface of the stirring rod 102, and is located below several spiral stirring blades 103.

[0109] The electromagnetic slider is located inside the vessel body 104 and within the curved sliding groove 301. The electromagnetic sliders are slidably connected to each other, and the sliding direction is rotation around the axial direction of the stirring rod 102. The electromagnetic slider is also electrically connected to the controller 1.

[0110] The rubber block is made of elastic material and is located inside the vessel body 104 and outside the stirring rod 102. The rubber block is fixedly connected to the outer side of the electromagnetic slider.

[0111] The inner fixing ring 303 is inclinedly disposed inside the vessel body 104 and sleeved on the outside of the stirring rod 102, located below the spiral stirring blade 103 and above the solenoid valve 106. A groove is provided on the inner surface of the inner fixing ring 303, and the groove matches the expanded rubber block.

[0112] Several fixing springs are respectively disposed inside the vessel body 104. Several fixing springs are respectively disposed on the side of the inner fixing ring 303 near the stirring rod 102. One end of each fixing spring is fixedly connected to the inner side of the inner fixing ring 303, and the other end is connected to the side of the stirring rod 102.

[0113] Several fixed plates are respectively arc-shaped plates and are respectively positioned between several fixed springs and stirring rod 102. The outer arc surfaces of several fixed plates are respectively fixedly connected to the other ends of several fixed springs, and the inner arc surfaces of the plates match the curvature of the outer side of the stirring rod 102 and are in contact with the outer side of the stirring rod 102.

[0114] Several outer ring connecting rods 304 are inclinedly arranged inside the vessel body 104 and are respectively located outside the inner fixed ring 303. One end of each of the outer ring connecting rods 304 is fixedly connected to the outer side of the inner fixed ring 303.

[0115] The cleaning ring 302 is disposed inside the vessel body 104 and is located outside the outer ring connecting rods 304. The center of the cleaning ring 302 coincides with the center of the inner fixed ring 303, and the inner side of the cleaning ring 302 is fixedly connected to the other end of the outer ring connecting rods 304.

[0116] Several cleaning scrapers are respectively disposed inside the vessel body 104 and located on the outer side of the cleaning ring 302. The cleaning scrapers are respectively fixedly connected to the outer side of the cleaning ring 302 and respectively contact the inner side of the vessel body 104.

[0117] Several closed sheaths are respectively fitted onto the outside of several fixed springs and are respectively fixedly connected to the inner side of the inner fixed ring 303.

[0118] After the user discharges the purified wastewater from the vessel 104, the user can control the drive motor 101 to switch control modes via the controller 1, causing the drive motor 101 to switch to an alternating forward and reverse working mode, and input cleaning agent into the vessel 104 through the water inlet pipe 105. After the wastewater is discharged from the vessel 104, the gas that entered the pure water tank 203 will return to the vessel 104, thereby increasing the air pressure inside the vessel 104. When the air pressure inside the vessel 104 increases again, since the rubber block is made of elastic material, it will expand when it senses the increase in external air pressure. Therefore, after the rubber block expands, it will embed into the groove provided on the inner side of the inner fixing ring 303, thereby connecting the inner fixing ring 303. When the drive motor 101 switches to the alternating forward and reverse working mode, the controller 1 also controls the electromagnetic slider to close, allowing the electromagnetic slider to slide along the curved sliding groove 301. When the drive motor 101 drives the stirring rod 102 to rotate forward or reverse, the electromagnetic slider will drive the rubber block to slide along the curved sliding groove 301. This allows the cleaning ring 302 to slide along the curved sliding groove 301 and rotate around the axis of the stirring rod 102, via the inner fixed ring 303 and several outer ring connecting rods 304. This allows the cleaning scrapers on the outer side of the cleaning ring 302 to move up and down while rotating around the axis of the stirring rod 102, thus scraping the inner side of the vessel body 104. This cleans the sludge adhering to the inner side of the vessel body 104. After cleaning, the user can open the solenoid valve 106 again, stop the drive motor 101, and start the electromagnetic slider to discharge the cleaned wastewater from the vessel body 104, avoiding affecting the next wastewater purification.

[0119] The quantitative flocculant dosing device also includes a pressure gauge 214. The pressure gauge 214 is located on the outside of the vessel body 104 and below the support 2. The measuring end of the pressure gauge 214 penetrates the side of the vessel body 104 and is connected to the inside of the vessel body 104.

[0120] Users can use the pressure gauge 214 to accurately determine whether the internal pressure of the vessel body 104 has reached the appropriate standard, and then choose whether to increase or decrease the pressure.

[0121] The wastewater purification device also includes an observation port 107. The observation port 107 is located on the side of the vessel body 104, below the support 2, and to the side of the pressure gauge 214. The observation port 107 is connected to the interior of the vessel body 104 and has a glass plate inside.

[0122] Users can observe the degree of wastewater purification and cleanliness inside the vessel 104 through the observation port 107, thereby observing the effect of wastewater sedimentation and the cleanliness inside the vessel 104.

[0123] The quantitative flocculant addition device also includes: a liquid level detector and a water filling pipe 215.

[0124] The liquid level detector is installed inside the pure water tank 203 and is fixedly connected to the top surface inside the pure water tank 203. The liquid level detector is also electrically connected to the controller 1.

[0125] One end of the water filling pipe 215 passes through the top of the pure water tank 203 and is connected to the inside of the pure water tank 203, while the other end is connected to the water supply pipe.

[0126] When the level detector detects that the liquid level inside the pure water tank 203 has not reached the set level, the level detector can send the value to the controller 1. After the user checks, they can open the water supply pipe and replenish the liquid inside the pure water tank 203 through the filling pipe 215.

[0127] The wastewater purification device also includes a temperature sensor 108 and a heater 109. The temperature sensor 108 is located on the outside of the vessel body 104 and on the outside of the support 2. The probe of the temperature sensor 108 passes through the side of the vessel body 104 and extends into the interior of the vessel body 104. The temperature sensor 108 is fixedly connected to the side of the support 2 and electrically connected to the controller 1.

[0128] The heater 109 is located inside the vessel body 104 and is fixedly connected to the inner top surface of the vessel body 104. The heater 109 is also electrically connected to the controller 1.

[0129] After the temperature sensor detects the temperature inside the vessel 104, it can transmit the reading to the controller 1. The user can then determine whether the temperature inside the vessel 104 has reached a suitable level based on the reading from the controller 1, and thus decide whether to activate the heater 109 through the controller 1 to raise the temperature inside the vessel 104 to reach the appropriate reaction temperature for the bio-flocculator.

[0130] The wastewater purification device also includes: a feed pipe 110, a second check valve 111, and a pH sensor 112.

[0131] The pH sensor 112 is located to the side of the temperature sensor 108 and to the outside of the bracket 2. The pH sensor 112 is fixedly connected to the outer side of the bracket 2, and its probe extends through the side of the vessel body 104 and into the interior of the vessel body 104. The pH sensor 112 is also electrically connected to the controller 1.

[0132] The second one-way valve 111 is located above the vessel body 104 and to the side of the drive motor 101. The second one-way valve 111 is located at the top of the vessel body 104 and communicates with the interior of the vessel body 104.

[0133] The feed pipe 110 is vertically positioned directly above the second check valve 111, and its bottom end is connected to the interior of the second check valve 111.

[0134] The pH sensor 112 can transmit the pH value of the wastewater inside the vessel 104 to the controller 1. After the controller 1 displays the reading, the user can determine whether it is necessary to open the second one-way valve 111 through the controller 1 to add relevant chemical reagents or more biological flocculants into the vessel 104 through the feed pipe 110 based on the pH value reading transmitted by the pH sensor 112.

[0135] Work process:

[0136] When a user wants to purify wastewater, they should first start the pressurized air pump 201 via controller 1. Once started, the pressurized air pump 201 will inject gas into the vessel 104 through the air pipe, filling the vessel 104 with gas. After the vessel 104 is filled with gas, the pressurized air pump 201 can be stopped via controller 1, and the electrically controlled air valve 212 will be opened, as well as the first one-way valve 213 and the third one-way valve 211 will be open for a certain period. Then, when the user injects wastewater into the vessel 104 through the water inlet pipe 105, whenever the liquid level inside the vessel 104 rises, the excess air will be forced into the purified water tank 203 through the electrically controlled air valve 212. At this time, the air pressure inside the pure water tank 203 will gradually increase, causing the liquid inside the pure water tank 203 to enter the buoyancy sensing tube 204 through the water pipe. As the liquid level inside the buoyancy sensing tube 204 gradually rises, the liquid level will exert buoyancy on the float 205, thereby reducing the tension of the float 205 on the tension spring 208 through the pull rope 206 and the stop block 207. This causes the tension spring 208 to retract, allowing the stop block 207 to move upward and open the obstruction of the first one-way valve 213. The higher the liquid level in the buoyancy sensing tube 204, the higher the position of the float 205 will be, resulting in a greater retraction of the tension spring 208. This reduces the obstruction of the stop block 207 on the first one-way valve 213, thereby controlling the amount of bio-flocculant inside the flocculant delivery tank 209 that falls onto the bottom surface of the flocculant delivery tank 209 through the delivery pipe 210 and the first one-way valve 213. When the bio-flocculant falls onto the bottom of the flocculant delivery box 209, it enters the vessel 104 through the third one-way valve 211. When the opening time of the first one-way valve 213 and the third one-way valve 211 is reached, the bio-flocculant that matches the amount of sewage is added into the vessel 104, achieving precise addition of the bio-flocculant and avoiding waste.

[0137] After the wastewater is purified and discharged from the vessel 104, the air that entered the pure water tank 203 will return to the vessel 104 through the electrically controlled air valve 212 due to the freed-up space inside the vessel 104. This allows the liquid inside the buoyancy sensor tube 204 to return to the pure water tank 203, causing the float 205 and tension spring 208 to return to their original positions and control the electrically controlled air valve 212 to close, thus avoiding affecting the quantitative addition of the bio-flocculator in the next cycle.

[0138] After the user discharges the purified wastewater from the vessel 104, the user can control the drive motor 101 to switch control modes via the controller 1, causing the drive motor 101 to switch to an alternating forward and reverse working mode, and input cleaning agent into the vessel 104 through the water inlet pipe 105. After the wastewater is discharged from the vessel 104, the gas that entered the pure water tank 203 will return to the vessel 104, thereby increasing the air pressure inside the vessel 104. When the air pressure inside the vessel 104 increases again, since the rubber block is made of elastic material, it will expand when it senses the increase in external air pressure. Therefore, after the rubber block expands, it will embed into the groove provided on the inner side of the inner fixing ring 303, thereby connecting the inner fixing ring 303. When the drive motor 101 switches to the alternating forward and reverse working mode, the controller 1 also controls the electromagnetic slider to close, allowing the electromagnetic slider to slide along the curved sliding groove 301. When the drive motor 101 drives the stirring rod 102 to rotate forward or reverse, the electromagnetic slider will drive the rubber block to slide along the curved sliding groove 301. This allows the cleaning ring 302 to slide along the curved sliding groove 301 and rotate around the axis of the stirring rod 102, via the inner fixed ring 303 and several outer ring connecting rods 304. This allows the cleaning scrapers on the outer side of the cleaning ring 302 to move up and down while rotating around the axis of the stirring rod 102, thus scraping the inner side of the vessel body 104. This cleans the sludge adhering to the inner side of the vessel body 104. After cleaning, the user can open the solenoid valve 106 again, stop the drive motor 101, and start the electromagnetic slider to discharge the cleaned wastewater from the vessel body 104, avoiding affecting the next wastewater purification.

[0139] Users can use the pressure gauge 214 to accurately determine whether the internal pressure of the vessel body 104 has reached the appropriate standard, and then choose whether to increase or decrease the pressure.

[0140] Users can observe the degree of wastewater purification and cleanliness inside the vessel 104 through the observation port 107, thereby observing the effect of wastewater sedimentation and the cleanliness inside the vessel 104.

[0141] When the level detector detects that the liquid level inside the pure water tank 203 has not reached the set level, the level detector can send the value to the controller 1. After the user checks, they can open the water supply pipe and replenish the liquid inside the pure water tank 203 through the filling pipe 215.

[0142] After the temperature sensor detects the temperature inside the vessel 104, it can transmit the reading to the controller 1. The user can then determine whether the temperature inside the vessel 104 has reached a suitable level based on the reading from the controller 1, and thus decide whether to activate the heater 109 through the controller 1 to raise the temperature inside the vessel 104 to reach the appropriate reaction temperature for the bio-flocculator.

[0143] The pH sensor 112 can transmit the pH value of the wastewater inside the vessel 104 to the controller 1. After the controller 1 displays the reading, the user can determine whether it is necessary to open the second one-way valve 111 through the controller 1 to add relevant chemical reagents or more biological flocculants into the vessel 104 through the feed pipe 110 based on the pH value reading transmitted by the pH sensor 112.
