Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an automated wastewater treatment device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering, and is increasingly becoming a part of everyday life for ordinary people. During wastewater treatment, chemicals need to be added.

[0003] A search revealed that patent application CN202011127378.X discloses an automated wastewater treatment device. While this device involves adding chemicals and water to a dosing tank 9 via an injection pipe 11 and a dosing pipe 12, and then starting a motor 14 to rotate a stirring shaft 15 and stirring teeth 16 to mix the chemicals and water in the dosing tank 9, and opening a valve 18 to add chemicals to the wastewater in the main body 1, this device cannot flexibly adjust the amount of chemicals added based on the dynamic changes in wastewater treatment volume. In actual wastewater treatment scenarios, wastewater discharge fluctuates significantly due to production activities, seasonal changes, and other factors. Existing devices can only maintain a fixed amount of chemicals, leading to overdosing when wastewater volume is low, resulting in wasted costs and potential secondary pollution; conversely, insufficient chemical supply when wastewater volume is high, failing to achieve the desired treatment effect and causing the effluent quality to fail to meet standards. In addition, the device is not equipped with a flow monitoring and feedback system, so operators cannot obtain information on the amount of wastewater treated in a timely manner and can only rely on experience to manually adjust the valves. This extensive operation mode further reduces the accuracy of the reagent ratio. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automated wastewater treatment device that solves the problems mentioned in the background section.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] An automated wastewater treatment device includes a tank, the top of which is provided with a top plate, and a drain pipe is provided on one side of the bottom of the tank;

[0007] A drive water wheel is installed on the top plate of the tank, and a delivery pump is installed on one side of the drive water wheel on the top plate of the tank. A drive shaft is installed on the drive water wheel, and the drive water wheel is connected to the delivery pump through the drive shaft. The delivery rate of the delivery pump is controlled by the water flow rate inside the drive water wheel.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the drive turbine is mounted on the top plate of the tank via a first bracket, and the delivery pump is mounted on the top plate of the tank via a second bracket.

[0010] The beneficial effects of adopting the above-mentioned further solutions are:

[0011] The first and second supports provide a stable support structure for the drive turbine and the transfer pump, allowing them to be securely mounted on the top plate of the tank. During equipment operation, the drive turbine rotates due to the impact of water flow, and the transfer pump also performs chemical delivery. The supports effectively distribute and withstand the forces and vibrations generated by these components, preventing the normal operation of the equipment from being affected by component shaking or displacement, and ensuring the stability and reliability of the entire wastewater treatment equipment structure.

[0012] Furthermore, the drive water turbine is equipped with an outlet pipe and an inlet pipe, both of which are arranged along the tangent direction of the drive water turbine, and the outlet pipe and the inlet pipe are perpendicular to each other.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] Wastewater enters the drive impeller tangentially from the inlet pipe. This inlet method allows the water flow to impact components such as the impact bowl inside the drive impeller with greater kinetic energy. Because the water flow direction matches the rotation direction of the drive impeller, the kinetic energy of the water flow can be converted into the mechanical energy of the drive impeller more effectively, thereby improving energy conversion efficiency and providing more sufficient power support for the operation of subsequent transfer pumps.

[0015] Furthermore, a fixed plate is rotatably installed inside the drive turbine, and an impact bowl is fixed on the fixed plate. The fixed plate is connected and fixed to one end of the drive shaft.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] When sewage impacts the impact bowl, the impact bowl transmits the impact force to the fixed plate, which in turn drives the drive shaft to rotate. This design efficiently converts the impact force of the water flow on the impact bowl into the rotational power of the drive shaft, reducing energy loss during transmission and ensuring that the drive turbine provides stable and sufficient power to the transfer pump, thus guaranteeing the normal operation of the entire system.

[0018] Furthermore, a worm and a worm wheel are rotatably installed inside the delivery pump, and the worm and the worm wheel mesh and drive each other. The end of the transmission shaft opposite to the drive turbine is connected to the worm for transmission.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] The drive shaft transmits the power generated by the driving water turbine to the worm gear, which meshes with the worm wheel for smooth power transmission. The meshing of the worm and worm wheel has a large transmission ratio, effectively reducing rotational speed and increasing torque, allowing the delivery pump to operate stably at a suitable speed and ensuring the accuracy and stability of the drug delivery. The transmission ratio design of the worm and worm wheel allows for convenient adjustment and control of the delivery pump's speed. When it is necessary to change the drug delivery rate, simply adjust the rotational speed of the driving water turbine (by changing the water flow rate, etc.), and the drive shaft transmits power to the worm gear, which drives the worm wheel to rotate, thereby changing the operating speed of relevant components within the delivery pump (such as the extrusion roller), achieving precise control of the drug delivery rate.

[0021] Furthermore, a connecting arm is connected to the worm gear, and extrusion wheels are rotatably installed at both ends of the connecting arm. The delivery pump is provided with a pipe groove, and a medicine pipe is provided in the pipe groove. A medicine outlet pipe and a medicine inlet pipe are respectively provided at both ends of the medicine pipe.

[0022] The beneficial effects of adopting the above-mentioned further solutions are:

[0023] The worm gear rotates, driving the connecting arm to rotate as well. The extrusion rollers at both ends of the connecting arm rotate accordingly, periodically extruding the chemical solution within the tubing. This extrusion method allows for precise control of the amount of chemical solution extruded each time, thus achieving accurate chemical delivery. By rationally designing the shape, size, and extrusion frequency of the extrusion rollers, the chemical dosage requirements of different wastewater treatment processes can be met, improving the effectiveness and quality of wastewater treatment.

[0024] This utility model provides an automated wastewater treatment device. It has the following beneficial effects:

[0025] This equipment cleverly utilizes the water energy of the sewage flow as a power source, eliminating the need for additional electrical energy to drive components such as the transfer pump. Sewage enters through the inlet pipe of the drive turbine, and the water flow impacts the impact bowl, driving the drive shaft to rotate, thereby providing power to the transfer pump. This achieves energy self-sufficiency and efficient utilization, reducing operating costs.

[0026] The delivery rate of the transfer pump can be automatically adjusted according to the water flow rate within the drive impeller. When the sewage flow is large and the water flow rate is fast, the drive impeller rotates faster, increasing the power transmitted to the transfer pump through the transmission shaft. This accelerates the worm gear transmission, increases the frequency of the extrusion wheel squeezing the chemical solution tube, and correspondingly increases the delivery rate. Conversely, when the sewage flow is small and the water flow rate is slow, the delivery rate automatically decreases. This intelligent adjustment mechanism ensures that the amount of chemical solution dispensed matches the sewage treatment volume, avoiding waste or insufficient solution, and improving the effectiveness and efficiency of sewage treatment. Just like during peak and off-peak water usage periods in households, the equipment can automatically adjust the amount of chemical solution dispensed to maintain optimal treatment conditions. The transfer pump delivers the chemical solution through worm gear transmission and the extrusion wheel squeezing the chemical solution tube, achieving relatively precise chemical delivery. The extrusion wheel periodically squeezes the chemical solution tube during rotation, precisely controlling the amount of solution squeezed each time, thus ensuring the accuracy of chemical solution dispensing. This is crucial for sewage treatment processes with strict requirements on chemical solution dosage, effectively improving the quality and effectiveness of sewage treatment. For example, when treating wastewater containing specific pollutants, it is necessary to precisely control the amount of chemical solution added to achieve the best treatment effect, and this equipment can meet this requirement.

[0027] Because this equipment is driven by the flow of wastewater itself, and the chemical delivery rate can be automatically adjusted according to the flow rate, it has strong adaptability. It can adapt to wastewater treatment needs with varying flow rates and water quality, functioning normally for both large-flow industrial wastewater treatment and relatively small-flow domestic wastewater treatment with fluctuating water quality. For example, in areas where seasonal rainfall causes significant variations in wastewater flow, the equipment can automatically adjust its operating status to maintain consistently good wastewater treatment results.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0038] Example 1

[0039] An automated wastewater treatment device includes a tank 1 with a top plate on top and a drain pipe 101 on one side of the bottom. A drive impeller 2 is mounted on the top plate of the tank 1, and a delivery pump 5 is mounted on the top plate of the tank 1 to one side of the drive impeller 2. The drive impeller 2 is mounted on the top plate of the tank 1 via a first bracket 3, and the delivery pump 5 is mounted on the top plate of the tank 1 via a second bracket 6. The first bracket 3 and the second bracket 6 provide a stable support structure for the drive impeller 2 and the delivery pump 5, allowing them to be firmly mounted on the top plate of the tank 1. During operation, the drive impeller 2 rotates due to water flow impact, and the delivery pump 5 delivers chemicals. The brackets effectively disperse and withstand the forces and vibrations generated by these components, preventing the normal operation of the device from being affected by component shaking or displacement, and ensuring the stability and reliability of the entire wastewater treatment device structure. A drive shaft 4 is mounted on the drive impeller 2, and the drive impeller 2 is connected to the delivery pump 5 via the drive shaft 4. The delivery rate of the delivery pump 5 is controlled by the water flow rate within the drive impeller 2.

[0040] Example 2

[0041] To further improve the performance and operational stability of wastewater treatment equipment and achieve more efficient and precise chemical dosing and wastewater treatment, for example, such as Figures 1 to 4As shown, this utility model also includes: a liquid outlet pipe 201 and a liquid inlet pipe 202 are provided on the drive water impeller 2. Both the liquid outlet pipe 201 and the liquid inlet pipe 202 are arranged along the tangential direction of the drive water impeller 2, and the liquid outlet pipe 201 and the liquid inlet pipe 202 are perpendicular to each other. Sewage enters the drive water impeller 2 tangentially from the liquid inlet pipe 202. This water intake method enables the water flow to impact the impact bowl 203 and other components inside the drive water impeller 2 with greater kinetic energy. Since the water flow direction matches the rotation direction of the drive water impeller 2, the kinetic energy of the water flow can be converted into the mechanical energy of the drive water impeller 2 more effectively, thereby improving the energy conversion efficiency and providing more sufficient power support for the operation of the subsequent delivery pump 5. A fixed plate 204 is rotatably mounted inside the drive impeller 2, and an impact bowl 203 is fixed on the fixed plate 204. The fixed plate 204 is connected and fixed to one end of the drive shaft 4. When sewage impacts the impact bowl 203, the impact bowl 203 transmits the impact force to the fixed plate 204, which drives the drive shaft 4 to rotate. This design can efficiently convert the impact force of the water flow on the impact bowl 203 into the rotational power of the drive shaft 4, reducing energy loss during transmission and ensuring that the drive impeller 2 can provide stable and sufficient power to the transfer pump 5, guaranteeing the normal operation of the entire equipment system. A worm gear 508 and a worm wheel 507 are rotatably mounted inside the transfer pump 5, and the worm gear 508 and the worm wheel 507 mesh and drive each other. The end of the drive shaft 4 opposite to the drive impeller 2 is connected to the worm gear 508. The drive shaft 4 transmits the power generated by the drive impeller 2 to the worm gear 508, and the worm gear 508 meshes and drives the worm wheel 507. This transmission method can achieve smooth power transmission. The meshing of the worm 508 and worm wheel 507 has a large transmission ratio, which can effectively reduce the rotational speed and increase the torque, enabling the delivery pump 5 to operate stably at a suitable speed and ensuring the accuracy and stability of the drug delivery. The transmission ratio design of the worm 508 and worm wheel 507 allows for convenient adjustment and control of the speed of the delivery pump 5. When it is necessary to change the liquid delivery rate, simply adjust the rotation speed of the drive turbine 2 (by changing the water flow rate, etc.). The drive shaft 4 transmits power to the worm gear 508, which drives the worm wheel 507 to rotate, thereby changing the operating speed of related components (such as the extrusion wheel 506) inside the delivery pump 5, achieving precise control of the liquid delivery rate. A connecting arm 505 is connected to the worm wheel 507, and extrusion wheels 506 are rotatably mounted at both ends of the connecting arm 505. The delivery pump 5 is provided with a pipe groove 503, and a liquid pipe 504 is provided inside the pipe groove 503. The two ends of the liquid pipe 504 are respectively provided with an outlet pipe 501 and an inlet pipe 502. The rotation of the worm wheel 507 drives the connecting arm 505 to rotate, and the extrusion wheels 506 at both ends of the connecting arm 505 rotate accordingly, periodically extruding the liquid pipe 504 inside the pipe groove 503. This extrusion method can precisely control the amount of liquid extruded each time, thereby achieving precise liquid delivery.By rationally designing the shape, size, and extrusion frequency of the extrusion roller 506, the requirements of different wastewater treatment processes for the dosage of chemicals can be met, thereby improving the effectiveness and quality of wastewater treatment.

[0042] Working principle:

[0043] Wastewater enters the drive impeller 2 tangentially from the inlet pipe 202. Since the inlet pipe 202 and the outlet pipe 201 are both arranged tangentially to the drive impeller 2 and are perpendicular to each other, the water flow into the drive impeller 2 will generate an impact force on the impact bowl 203, causing the fixed plate 204 to rotate inside the drive impeller 2, which in turn causes the drive shaft 4 connected to the fixed plate 204 to start rotating.

[0044] After the drive shaft 4 rotates, it transmits power to the worm 508 inside the delivery pump 5. In the delivery pump 5, the worm 508 meshes with the worm wheel 507, and the worm wheel 507 rotates accordingly.

[0045] When the worm gear 507 rotates, it drives the connecting arm 505 to rotate, and the extrusion rollers 506 at both ends of the connecting arm 505 also rotate accordingly. During the rotation, the extrusion rollers 506 periodically extrude the medicine tube 504 in the tube groove 503. When the extrusion rollers 506 extrude the medicine tube 504, the medicine in the medicine tube 504 is squeezed and discharged from the medicine outlet pipe 501; when the extrusion rollers 506 leave the medicine tube 504, the medicine tube 504 returns to its original shape under its own elasticity and draws in new medicine from the medicine inlet pipe 502. This cycle repeats continuously, realizing the delivery of medicine. Furthermore, the delivery rate of the delivery pump 5 is controlled by the water flow rate within the drive turbine 2. The faster the water flow rate, the higher the rotational speed of the drive turbine 2, which in turn increases the rotational speed of the transmission shaft 4. This, in turn, increases the rotational speed of the worm gear 508 and worm wheel 507, and increases the frequency at which the extrusion wheel 506 extrudes the liquid medicine pipe 504, resulting in a faster delivery rate. Conversely, the slower the water flow rate, the slower the delivery rate. The treated wastewater is discharged from the drain pipe 101 on one side of the bottom of the tank 1.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
