Description

Technical Field

[0001] This invention relates to the field of industrial wastewater purification technology, specifically to an industrial wastewater purification device for thermal power plants. Background Technology

[0002] Thermal power plants are power plants that use the heat energy released by the combustion of combustibles to produce electricity. During the production process, thermal power plants generate various types of wastewater. If discharged directly, it will seriously pollute the environment. Therefore, it must be purified and treated to meet the standards before it can be discharged or reused.

[0003] For example, the invention disclosed in publication number CN118993210A is an industrial wastewater purification device for thermal power plants. This invention solves the problem that some wastewater does not react completely with the treatment agent before flowing down through the activated carbon plate, reducing the reaction time and effect between the wastewater and the treatment agent, thus reducing the quality of wastewater treatment. However, in actual use, the addition of flocculants such as alum causes suspended solids and colloidal impurities in the wastewater to agglomerate into larger flocs for subsequent separation. These flocs gradually settle downwards under gravity and easily accumulate on the filter screen at the bottom of the device, causing the screen to become clogged. On the one hand, the accumulation of flocs increases the resistance to water flow, reduces the water output efficiency of the device, and in severe cases, may even cause the system to malfunction. On the other hand, the accumulated flocs are difficult to separate and discharge quickly, increasing operation and maintenance costs and labor intensity. Summary of the Invention

The piston cylinder is fixedly connected to the mounting base. Dust covers are connected to the front two ends of the piston cylinder through one-way valves, and air collection pipes are installed at the top two ends of the piston cylinder through one-way valves. A sealing ring is rotatably connected to the top of one end of the air collection pipe through a dynamic seal. An air inlet is opened at the bottom of the transmission seat, and a one-way jet nozzle is installed on the top of the scraper.

[0009] Furthermore, the one-way jet head is connected to the air inlet through the internal flow channel of the scraper and the transmission seat, and the transmission seat abuts against the rubber layer on the top of the sealing ring.

[0010] Furthermore, a first magnetic ring is fixedly connected to the lower outer side of the transmission seat, and a second magnetic ring is magnetically connected to the bottom of the first magnetic ring, and the second magnetic ring is fixedly connected to the air collecting pipe.

[0011] Furthermore, a pushing assembly is provided on the upper part of the barrel, and the pushing assembly includes a central gear. The upper part of the reciprocating screw is connected to the central gear through a one-way bearing, and a planetary gear meshes with the outer side of the central gear. A gear ring meshes with one side of the planetary gear, and a rotating cover is fixedly connected to the outer side of the gear ring. A hanging rod is installed on the outer side of the rotating cover, and a stop bar is fixedly connected to the lower part of the hanging rod.

[0014] Furthermore, the bristles are attached to the filter plate, and the hanging rods are arranged in a circumferential array about the inside of the barrel.

[0015] This invention provides an industrial wastewater purification device for thermal power plants, which has the following beneficial effects: 1. This invention adopts an integrated linkage transmission structure, realizing the phased automatic continuous operation of stirring, settling and drainage, and bottom discharge in industrial wastewater treatment, which significantly improves treatment efficiency and automation level. During the treatment process, driven by a single motor, the working mode can be automatically switched by the cooperation of unidirectional transmission and guiding mechanism. First, stirring is performed to promote the full mixing of flocculant and sewage and accelerate the flocculation reaction. After settling, the mechanism automatically switches to slow lifting and drainage, so that the clarified supernatant can pass smoothly through the filter plate, effectively avoiding a large number of flocculent particles directly impacting and clogging the filter holes, reducing the frequency of cleaning. Finally, the mechanism resets and rotates again to push the deposited sludge to the discharge port. The whole process does not require frequent manual intervention, greatly reducing the labor intensity of operation and realizing efficient and stable wastewater pretreatment.

[0016] 2. This invention significantly improves the mixing efficiency of flocculant and wastewater by integrating a pneumatic enhanced mixing structure without adding an independent power source. During the mixing process, the mechanism can automatically generate compressed air using the driving force of the original motor and release a large number of microbubbles through the rotating nozzle. These bubbles generate strong shear and disturbance to the water body during their ascent, expanding the mixing range, eliminating dead zones in the mixing, and allowing the flocculant and pollutants to come into more sufficient contact, thereby accelerating the flocculation reaction and shortening the mixing time. During the drainage stage, the pneumatic mechanism automatically stops working, reducing energy consumption. Furthermore, during the sewage discharge stage, the airflow can prevent nozzle clogging, ensuring the long-term stable operation of the equipment.

[0017] 3. This invention effectively maintains the long-term unobstructed flow and filtration efficiency of the filter plate through a linkage-driven automatic anti-clogging mechanism. During drainage, the mechanism uses a transmission system to rotate at low speed, continuously brushing the surface of the filter plate with bristles to push attached or accumulated impurities downwards, preventing filter pore blockage. At the same time, in conjunction with spiral baffles, the pushed-down impurities can be guided and collected in the lower area, effectively preventing impurities from floating back up and clogging the filter screen. This design achieves continuous self-cleaning of the filter plate, greatly reducing the frequency of manual shutdown for cleaning and maintenance, and ensuring the overall processing capacity and operational stability of the equipment.

[0020] Please see Figures 1 to 4 The present invention provides a technical solution: an industrial wastewater purification device for a thermal power plant, comprising a tank body 1 and a moving assembly 7. A tank cover 2 is mounted on the top of the tank body 1, with an inlet pipe 3 mounted on one side of the top of the tank cover 2 and a dosing pipe 4 mounted on the other side of the top of the tank cover 2. A filter plate 5 is fixedly connected to the upper part of the tank body 1, and a collection pipe 6 is mounted on the upper outer side of the tank body 1. The moving assembly 7 is connected to the middle of the tank cover 2, and the moving assembly 7 includes a motor 701. The output end of the motor 701 is connected to a reciprocating screw 702, and the lower outer side of the reciprocating screw 702 is sleeved with... A transmission base 703 is provided. A support cylinder 704 is connected to the outer side of the transmission base 703 via a one-way bearing. A guide strip 705 is slidably connected to the outer side of the support cylinder 704. The guide strip 705 is fixedly connected to the barrel body 1. The barrel body 1 is slidably connected to the support cylinder 704 via a sealing element. A scraper 706 is fixedly connected to the upper outer side of the transmission base 703. A corrugated telescopic tube 707 is installed on the top of the transmission base 703. The scraper 706 is slidably connected to the support cylinder 704. The interior of the scraper 706 is hollow. A drain valve 8 is fixedly connected to the bottom of the support cylinder 704. The specific operation is as follows: When adding wastewater and flocculant into the tank 1 through the inlet pipe 3 and the dosing pipe 4, and the liquid level at the time of addition is lower than the filter plate 5, the controller starts the motor 701, which drives the reciprocating screw 702 to rotate counterclockwise. At this time, the one-way bearing between the transmission seat 703 and the support cylinder 704 is in a free-spinning state. Since the rotation of the transmission seat 703 cannot be restricted, the transmission seat 703 will rotate synchronously with the reciprocating screw 702 without vertical displacement. At the same time, the transmission seat 703 will also drive the scraper 706 to rotate synchronously, automatically and continuously agitating the sewage inside the tank 1, which is beneficial to improving the mixing efficiency of flocculant and sewage, and enabling the flocculant to be quickly and evenly dispersed. Throughout the water body, the flocculation reaction is accelerated and fully carried out. After mixing stops and the mixture is allowed to stand for a period of time, suspended impurities in the wastewater will form larger floc particles under the flocculation effect of the flocculant and gradually settle downwards. The impurity content in the supernatant at the top of the wastewater is significantly reduced, and the water quality is initially purified. At this time, the controller can start the motor 701 to drive the reciprocating screw 702 to rotate clockwise. Since the one-way bearing between the transmission seat 703 and the support cylinder 704 is in a locked state, and the guide bar 705 restricts the circumferential rotation of the support cylinder 704, thereby restricting the rotation of the transmission seat 703, when the reciprocating screw 702 rotates clockwise, it can drive the transmission seat 703 to slowly move the support cylinder 704 upwards. This allows the water level inside the tank 1 to rise steadily to the filter plate 5. Since the upper water has already settled and clarified, the impurity content at the filter plate 5 is significantly reduced. This prevents a large number of flocculent particles from directly impacting and clogging the filter holes of the filter plate 5, thus affecting the drainage rate and filtration effect, and effectively reducing the frequency of cleaning and replacement. At the same time, the water further filtered by the filter plate 5 can be collected through the collection pipe 6 for subsequent deep treatment such as activated carbon adsorption. Furthermore, the corrugated telescopic pipe 707 can be used to cover and protect the outside of the reciprocating screw 702, effectively preventing impurities and flocculents in the sewage from adhering to the screw thread surface, avoiding jamming or abnormal wear when the transmission seat 703 moves, and ensuring the lifting and lowering operation. The system ensures smooth operation and reliability. After all the supernatant is discharged, the reciprocating screw 702 drives the support cylinder 704 to move down and reset to its initial position. Then, the controller starts the motor 701, which drives the reciprocating screw 702 to rotate counterclockwise and open the drain valve 8. At this time, the transmission seat 703 drives the scraper 706 to rotate again, which can gradually push the sediment at the bottom of the tank 1 to the drain valve 8 for discharge, facilitating centralized collection and subsequent disposal. Through this mechanical linkage structure, the equipment can realize the staged automatic continuous treatment functions of stirring purification, static drainage and bottom sewage discharge, effectively reducing the labor intensity of operators and thus significantly improving the overall efficiency and automation level of industrial wastewater treatment.

[0021] Please see Figures 3 to 6The lower part of the barrel body 1 is provided with an air mixing assembly 9, which includes a support leg 901. The support leg 901 is fixedly connected to the lower part of the barrel body 1, and a mounting base 902 is placed on one side of the middle part of the support leg 901. A crankshaft 903 is rotatably connected to the top of one end of the mounting base 902. The crankshaft 903 is connected to a reciprocating screw 702 through a one-way coupling. A connecting rod 904 is sleeved on the outer side of the middle part of the crankshaft 903. A piston rod 905 is rotatably connected to one end of the connecting rod 904. A piston cylinder 906 is slidably connected to the outer side of the piston rod 905. The piston cylinder 906 is fixedly connected to the mounting base 902. Dust covers 907 are connected to both ends of the front part of the piston cylinder 906 through one-way valves. Furthermore, both ends of the piston cylinder 906 are equipped with air collection pipes 908 via one-way valves. The top of one end of the air collection pipe 908 is rotatably connected to a sealing ring 909 via a dynamic seal. The bottom of the transmission seat 703 is provided with an air inlet 910. The top of the scraper 706 is provided with a one-way jet head 911. The one-way jet head 911 is connected to the air inlet 910 through the internal flow channels of the scraper 706 and the transmission seat 703. The transmission seat 703 abuts against the rubber layer on the top of the sealing ring 909. The lower outer side of the transmission seat 703 is fixedly connected to a first magnetic ring 10. The bottom of the first magnetic ring 10 is magnetically connected to a second magnetic ring 11. The second magnetic ring 11 is fixedly connected to the air collection pipe 908. The specific operation is as follows: When the reciprocating screw 702 rotates counterclockwise to stir and mix, it also drives the crankshaft 903 to rotate synchronously through a one-way clutch. As the crankshaft 903 rotates continuously, it can push and pull the piston rod 905 back and forth through the connecting rod 904, periodically changing the spatial volume of the chambers on both sides of the piston cylinder 906. When the space of one side of the chamber increases, external air will be drawn into the chamber through the corresponding dust cover 907 and one-way valve. When the space of the side chamber decreases, the compressed air in the chamber will be delivered to the air collection pipe 908 through the corresponding one-way valve. The chambers alternately draw in and exhaust air, achieving a continuous and stable air supply function and ensuring the uniformity of air supply pressure and flow rate. At this time, under the magnetic attraction of the first magnetic ring 10 and the second magnetic ring 11, the bottom end face of the transmission seat 703 can be kept in close contact with the rubber layer on the sealing ring 909, effectively improving the sealing performance of the rotating connection. Subsequently, the airflow in the air collecting pipe 908 will enter the flow channel inside the transmission seat 703 and the scraper 706 through the air inlet 910, and then be ejected outward from the one-way jet head 911. The large number of microbubbles generated can form strong shear and disturbance on the water during the rising process. This mechanism significantly improves the mixing efficiency of wastewater and flocculant particles, allowing for more thorough contact between the flocculant and pollutants, accelerating the flocculation reaction process, and shortening the mixing time. Simultaneously, the unidirectional jet nozzle 911 rotates synchronously with the scraper 706, creating bubble turbulence over a wider area, expanding the gas-liquid mixing range, eliminating dead zones, and further improving mixing uniformity and efficiency. Furthermore, this gas-mixing component 9 directly utilizes the existing motor 701 as a power source, eliminating the need for additional drive equipment. Its compact structure and high integration reduce manufacturing and maintenance costs. During the drainage process, as the reciprocating screw 702 rotates in the opposite direction, the one-way clutch will automatically disconnect the transmission connection between the reciprocating screw 702 and the crankshaft 903, causing the air-mixing assembly 9 to stop working. This effectively reduces the operating load of the motor 701, reduces unnecessary energy consumption, and achieves energy-saving operation. Subsequently, during the discharge of sewage, the one-way jet nozzle 911 can also spray air. The impact of the airflow prevents the sewage from drying and caking on the jet nozzle 911, preventing the jet channel from being blocked and affecting the next use. This ensures the long-term stable operation of the equipment and reduces the frequency of cleaning and maintenance.

[0022] Please see Figure 7The upper part of the barrel 1 is provided with a pushing assembly 12, which includes a central gear 1201. The upper part of the reciprocating screw 702 is connected to the central gear 1201 through a one-way bearing. The outer side of the central gear 1201 is meshed with a planetary gear 1202. One side of the planetary gear 1202 is meshed with a gear ring 1203. The outer side of the gear ring 1203 is fixedly connected with a rotating cover 1204. The outer side of the rotating cover 1204 is provided with a hanging rod 1205. The lower part of the hanging rod 1205 is fixedly connected with a baffle 1206. The baffle 1206 is spirally distributed and the cross section of the baffle 1206 is inclined. The outer side of the baffle 1206 is provided with bristles 1207. The bristles 1207 are in contact with the filter plate 5. The hanging rod 1205 is arranged in a circumferential array about the inner side of the barrel 1. The specific operation is as follows: When the reciprocating screw 702 rotates counterclockwise to stir and mix, the one-way bearing between the reciprocating screw 702 and the central gear 1201 is in an idle state and does not transmit power. Therefore, the pushing component 12 does not participate in the work. During the drainage process, when the reciprocating screw 702 rotates clockwise to drive the transmission seat 703 to move slowly upward, it will simultaneously drive the central gear 1201 to rotate synchronously. After the planetary gear 1202 reduces the speed and increases the torque, it drives the gear ring 1203 to rotate counterclockwise. This, along with the multiple hanging rods 1205 on the outside of the rotating cover 1204, drives the baffle 1206 and the bristles 1207 to rotate synchronously at a lower speed. Therefore, when some of the less dense floating impurities move towards the surface of the filter plate 5 with the rising water flow, they are distributed in a spiral shape. During the continuous brushing of the filter plate 5 surface, the bristles 1207 can gradually push the impurities attached to or accumulated at the filter holes downwards, effectively preventing impurities from accumulating and clogging the filter holes on the surface of the filter plate 5, and maintaining the effective water flow area of ​​the filter plate 5. At the same time, the cross-section of the baffle 1206 is inclined, which can restrict and collect the floating impurities pushed down by the bristles 1207 in the angle space formed between the baffle 1206 and the inner wall of the barrel 1. The spiral guiding effect of the baffle 1206 gradually guides the impurities to the lower area, preventing the impurities pushed down from floating up with the water flow again and clogging the filter plate 5. This achieves a continuous and stable automatic anti-clogging function, ensuring the water output efficiency and filtration effect of the filter plate 5, reducing the frequency of manual shutdown for cleaning and maintenance, and improving the overall processing capacity.

[0023] In summary, this type of industrial wastewater purification equipment for thermal power plants is used as follows: First, wastewater and flocculant are added into the tank 1 through the inlet pipe 3 and the dosing pipe 4, and the liquid level is controlled to be lower than the filter plate 5. Then, the motor 701 is started to drive the reciprocating screw 702 to rotate counterclockwise. The one-way bearing between the transmission seat 703 and the support cylinder 704 rotates freely. The transmission seat 703 rotates synchronously with the reciprocating screw 702 without moving up or down. At the same time, the transmission seat 703 will drive the scraper 706 to rotate synchronously, stirring the sewage in the tank 1. Secondly, when the reciprocating screw 702 rotates counterclockwise, it will also drive the crankshaft 903 to rotate synchronously through the one-way clutch. The piston rod 905 is pushed and pulled back and forth through the connecting rod 904, which periodically changes the volume of the chambers on both sides of the piston cylinder 906. External air enters the chamber through the dust cover 907 and the one-way valve, and is then delivered to the air collection pipe 908 through the one-way valve. The airflow enters the transmission seat 703 and the internal flow channel of the scraper 706 through the air inlet 910, and is ejected from the one-way jet nozzle 911 to accelerate the mixing efficiency. At the same time, the magnetic attraction of the first magnetic ring 10 and the second magnetic ring 11 makes the rubber layer on the transmission seat 703 and the sealing ring 909 stick tightly. During this process, the one-way bearing between the reciprocating screw 702 and the central gear 1201 rotates freely, and the push assembly 12 does not work. Next, after stopping the stirring, the mixture is allowed to settle, allowing impurities in the wastewater to form flocs and settle downwards, while a supernatant is formed at the top. The motor 701 is started to drive the reciprocating screw 702 to rotate clockwise. The one-way bearing between the transmission seat 703 and the support cylinder 704 is locked, and the guide bar 705 restricts the rotation of the support cylinder 704. The reciprocating screw 702 drives the transmission seat 703 to slowly move the support cylinder 704 upwards, and the water level in the tank 1 rises to the filter plate 5. The supernatant is filtered by the filter plate 5 and collected through the collection pipe 6. The corrugated telescopic pipe 707 can cover and protect the outside of the reciprocating screw 702. Then, during the drainage process, the one-way clutch disconnects the transmission between the reciprocating screw 702 and the crankshaft 903, and the air-mixing assembly 9 stops working. At the same time, the reciprocating screw 702 drives the central gear 1201 to rotate synchronously through the one-way bearing, which in turn drives the gear ring 1203 to rotate via the planetary gear 1202. This rotation is achieved by the hanging rod 1205 on the outside of the rotating cover 1204, which drives the baffle 1206 and the bristles 1207 to rotate synchronously. As the spirally distributed bristles 1207 brush the surface of the filter plate 5, they also push impurities downwards. The baffle 1206, with its inclined cross-section, confines floating impurities within the angled space between the baffle 1206 and the inner wall of the barrel 1, preventing them from floating back up. Finally, after the supernatant is drained, the reciprocating screw 702 drives the support cylinder 704 to move down and reset. The starting motor 701 drives the reciprocating screw 702 to rotate counterclockwise, opening the drain valve 8. The transmission seat 703 drives the scraper 706 to rotate, pushing the sediment at the bottom of the tank 1 to the drain valve 8 for discharge. During the discharge process, the one-way jet nozzle 911 sprays air to prevent subsequent sediment from drying and clogging the jet nozzle.
