Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, in particular to a wastewater decontamination device for chemical fiber oil production. Background Art

[0002] Chemical fiber oil production produces wastewater, which contains impurities, reaction products and by-products generated by unwashed raw materials. The composition is complex and the chemical oxygen demand is high. Equipment cleaning also produces wastewater, which contains pollutants such as chemical fiber oil, raw materials, and surfactants. The wastewater is mixed together during transportation. Generally, a sedimentation tank is used to add flocculants for precipitation. The impurities in the sewage will sink after flocculation. Water is continuously pumped from above to ensure that the impurities sink to the bottom of the sedimentation tank, thereby achieving decontamination.

[0003] The wastewater decontamination devices currently used achieve sedimentation decontamination by manually adding flocculants or using mechanical equipment to quantitatively add flocculants. This makes it inconvenient to input flocculants in equal amounts during the transportation process.

[0010] Optionally, the telescopic ends of the conveying pistons are both set upward, and the telescopic ends of the conveying pistons are fixedly provided with connecting strips, and the bottom adjacent ends of the two sets of connecting strips are fixedly provided with racks, the tooth surfaces of the two sets of racks are adjacent, and the two sets of racks are engaged with the synchronous gears; the bottom of the front rack extends downward and is fixedly provided with a strip sliding frame, and the transmission rod slides in the strip sliding frame; the two sets of racks are staggered, and when one set of racks rises, the other set of racks descends; the two sets of racks are slidably connected to the gear rack.

[0012] Optionally, the bottom two sides of the sedimentation box are vertical plate structures extending downward; an output pipe is fixedly provided on the top rear side of the sedimentation box, and the output pipe turns and bends rearward and downward; a sewage pipe is provided on the bottom rear side of the sedimentation box, and a ball valve is connected to the sewage pipe; a breathing adjustment pipe is fixedly connected to the middle of the top of the sedimentation box, and a gate valve is fixedly provided in the breathing adjustment pipe, and the position of the gate valve is higher than the output pipe; the main body of the sedimentation box is made of transparent PVC tempered glass.

[0014] Optionally, a pipeline is provided at the front end of the feeding channel to connect to the outside of the two sets of gas outlet one-way valves.

[0015] The beneficial effects are as follows: The present invention has the function of inputting flocculants in equal amounts, and is executed by the power of sewage. When the sewage passes through the eccentric channel, the pressure drives the driven impeller to rotate, and the rotating shaft of the driven impeller rotates, and the feeding impeller is driven to rotate by a chain. During the rotation of the feeding impeller, the flocculant powder in the upper feeding ladder bucket continuously falls into the surface groove of the feeding impeller, moves with the feeding impeller, and falls downward from the bottom of the feeding impeller to be input into the interior of the feeding channel. The input speed is in a constant proportion to the sewage flow rate, and the input can be kept stable.

[0016] The present invention can push the flocculant by generating a stable airflow internally. When one group of delivery pistons extends, the other group of delivery pistons contracts, which will cause the air pressure in the dosing bin to decrease while the internal pressure of the feeding channel to increase. Then, the air in the feeding channel flows into the dosing bin, generating an airflow, and blowing the flocculant in the feeding channel into the dosing bin, contacting the dosing baffle and falling into the expansion channel, and evenly contacting the sewage.

[0017] In addition, since the air flow inside the dosing bin only circulates and does not increase or decrease, the air pressure balance can be guaranteed. When the sewage passes through the expansion channel, the air pressure in the dosing bin restricts the sewage from flowing upward, and the sewage surface is flush with the bottom of the dosing bin. If the sewage continues to be pressurized, it will flow backward and enter the sedimentation tank.

[0018] In the present invention, the main body of the sedimentation box is made of transparent PVC tempered glass material, and the internal situation can be observed from the outside. After the sewage is mixed with flocculant and enters the input sedimentation box, it continues to accumulate, the water level continues to rise, and it is automatically layered through coagulation, impurities sink, and the degraded water rises. After the water level fills the output pipe, it is discharged from the rear end of the output pipe. When the impurity water level inside the sedimentation box is too high, the sewage transportation is stopped, the gate valve is opened, and then the ball valve is opened, and the precipitated sewage sediment is discharged from the ball valve for recycling and treatment.

[0032] Flocculants are a type of chemical used in water treatment and other fields to cause suspended particles in water to aggregate and enlarge or form flocs, thereby accelerating particle sedimentation. Flocculants include inorganic flocculants (such as aluminum sulfate and polyaluminum chloride), organic polymer flocculants (such as polyacrylamide), and microbial flocculants. They destabilize suspended particles and achieve solid-liquid separation through the principles of double layer compression, adsorption bridging, net capture and sweeping, and electrical neutralization. They are widely used in sewage treatment. The principle of flocculants is that, on the one hand, by compressing the double layer, high-valent cations enter the double layer of colloidal particles, reducing the surface potential and the thickness of the double layer to weaken the electrostatic repulsion; on the other hand, by using adsorption bridging, the active groups on the polymer molecular chain are adsorbed on the surface of the colloidal particles, bridging the particles to form flocs. At the same time, when the dosage is large, a net-capturing sweep is generated, and the large-volume flocs generated capture particles during the sedimentation process. In addition, through electrical neutralization, the surface charge of the colloidal particles is neutralized with opposite charges, ultimately promoting the coagulation and precipitation of the colloidal particles and suspended particles. like Figures 1-8 As shown, when treating sewage, the flocculant powder is poured into the feeding ladder bucket 1 in advance, and the sewage pump 9 is connected to the sewage source, and the sewage is continuously input into the eccentric channel 4 through the input pipe 8; Alternatively, a sewage pipe with power transmission is directly connected to the front end of the eccentric channel 4, and the sewage is continuously input into the eccentric channel 4. After the sewage flows through the eccentric channel 4, it enters the expansion channel 602 and then enters the sedimentation tank 7. As the sewage passes through the eccentric channel 4, the pressure pushes the driven impeller 401 to rotate. The rotating shaft of the driven impeller 401 rotates, and the feeding impeller 201 is driven by a chain to rotate. During the rotation of the feeding impeller 201, the flocculant powder in the upper feeding ladder bucket 1 continuously falls into the outer groove of the feeding impeller 201, moves with the feeding impeller 201, and falls downward from the bottom of the feeding impeller 201 and is input into the interior of the feeding channel 3. The chain used on the left side of the rotating shaft of the feeding impeller 201 and the driven impeller 401 can adjust the transmission ratio as needed. For example, by using large and small sprockets to change the speed of the driven impeller 401 and the feeding impeller 201, the speeds thereof can be different, thereby varying the efficiency of feeding the flocculant. In addition, the chain can be replaced with other transmission structures such as gears as needed to achieve transmission, which can be adjusted according to cost and actual use environment. At the same time, the transmission wheel 402 and the transmission rod 403 rotate, and the transmission rod 403 slides in the strip slide frame 506, driving the strip slide frame 506 to reciprocate up and down, and then the strip slide frame 506 drives the front rack 505 to reciprocate up and down, and the front rack 505 cooperates with the synchronous gear 203 to drive the rear rack 505 to move up and down. The front and rear racks 505 move asynchronously, causing the front and rear delivery pistons 503 to extend and retract alternately; When the delivery piston 503 extends, negative pressure is generated, which extracts the air in the mixing chamber 6. The air in the mixing chamber 6 passes through the pipeline and the air inlet check valve 501 and enters the delivery piston 503 for automatic filling. When the delivery piston 503 contracts, the air is squeezed out, and the air in the delivery piston 503 passes through the air outlet one-way valve 502 and the externally connected pipe and is input into the feeding channel 3, causing the flocculant to move backward; The two groups of delivery pistons 503 have the same volume and the same movement amplitude. Therefore, when one group of delivery pistons 503 extends, the other group of delivery pistons 503 contracts, causing the air pressure in the mixing bin 6 to decrease while the internal pressure of the feeding channel 3 to increase. Then, the air in the feeding channel 3 flows into the mixing bin 6, generating airflow, which also blows the flocculant in the feeding channel 3 into the mixing bin 6. When the flocculant contacts the admixture baffle 601, it diffuses and falls into the expansion channel 602, where it comes into contact with the sewage evenly. Through the above effects, the air pressure inside the dosing bin 6 can be kept balanced, and the air inside it will not decrease. When the sewage passes through the expansion channel 602, the air pressure inside the dosing bin 6 restricts the sewage from flowing upward, and the sewage surface is flush with the bottom of the dosing bin 6. Continuing to pressurize the sewage will cause it to flow backward and enter the sedimentation tank 7.

[0033] Example 2: Based on Example 1, the sewage pump 9 is not powered by the driven impeller 401 during the sewage transportation process, but sewage transportation is not limited to the sewage pump 9. Any other method that can boost the pressure to transport sewage or use other boosting equipment to transport sewage can maintain the decontamination effect of the device.

[0034] Example 3: Based on Example 1, the main body of the sedimentation box 7 is made of transparent PVC tempered glass and can be observed from the outside; After the sewage mixed with flocculants enters the sedimentation tank 7, it continues to accumulate, the water level continues to rise, and it is automatically stratified through flocculation, impurities sink, and the decontaminated water rises; If the output pipe 701 is directly emptied, for example, the rear end of the output pipe 701 is directly connected to the top of the pool, the gate valve 704 is opened, and when the water level rises, it enters the breathing pipe 703 and the output pipe 701. When the water level fills the output pipe 701, it is discharged from the rear end of the output pipe 701; If the output pipe 701 is also connected to the next-stage processing equipment, the gate valve 704 is closed, the air pressure inside the sedimentation tank 7 is kept normal, and the water is transported from the rear end of the output pipe 701 to the next-stage processing equipment; When it is observed that the impurity water level inside the sedimentation box 7 is too high, stop the sewage transportation, open the gate valve 704, then open the ball valve 702, and discharge the settled sewage sediment from the ball valve 702 for recycling and treatment. Close the ball valve 702 and input sewage again for sedimentation.

[0035] Specific usage and function of this embodiment: In the present invention, when in use, the sewage pump 9 is connected to the sewage source, and the sewage is continuously input into the eccentric channel 4 through the input pipe 8, or a sewage pipe with power transmission is directly connected to the front end of the eccentric channel 4, and the sewage is continuously input into the eccentric channel 4. The sewage flows through the eccentric channel 4 into the expansion channel 602 and then into the sedimentation tank 7; Pour the flocculant powder into the feeding ladder hopper 1; As the sewage passes through the eccentric channel 4, the pressure pushes the driven impeller 401 to rotate. The rotating shaft of the driven impeller 401 rotates, and the feeding impeller 201 is driven by a chain to rotate. During the rotation of the feeding impeller 201, the flocculant powder in the upper feeding ladder bucket 1 continuously falls into the outer groove of the feeding impeller 201, moves with the feeding impeller 201, and falls downward from the bottom of the feeding impeller 201 and is input into the interior of the feeding channel 3. When the driven impeller 401 rotates, it also drives the transmission wheel 402 and the transmission rod 403 to rotate. The transmission rod 403 slides in the strip slide frame 506, driving the strip slide frame 506 to move up and down, and then the strip slide frame 506 drives the front rack 505 to move up and down, and the front rack 505 cooperates with the synchronous gear 203 to drive the rear rack 505 to move up and down. The front and rear racks 505 move asynchronously, causing the front and rear delivery pistons 503 to extend and retract alternately; when the delivery piston 503 extends, negative pressure is generated, and the air in the mixing bin 6 is extracted. The air in the mixing bin 6 passes through the pipeline and the air inlet one-way valve 501 into the delivery piston 503 for automatic filling. When the delivery piston 503 contracts, the air is squeezed out and passed through the air outlet one-way valve 502 and the externally connected pipeline into the feeding channel 3, causing the flocculant to move backward; The two groups of delivery pistons 503 have the same volume and the same movement amplitude. When one group of delivery pistons 503 extends, the other group of delivery pistons 503 contracts, which causes the air pressure in the mixing bin 6 to decrease while the internal pressure of the feeding channel 3 to increase. Then, the air in the feeding channel 3 flows into the mixing bin 6, generating airflow, blowing the flocculant in the feeding channel 3 into the mixing bin 6, contacting the mixing baffle 601 and falling into the expansion channel 602, and evenly contacting the sewage. As a result, the air pressure inside the mixing bin 6 can be kept balanced, and the air inside it will not decrease. When the sewage passes through the expansion channel 602, the air pressure inside the mixing bin 6 prevents the sewage from flowing upward, and the sewage surface is flush with the bottom of the mixing bin 6. If the sewage continues to be pressurized, it will flow backward and enter the sedimentation tank 7. The sedimentation tank 7 can be observed from the outside. After the sewage mixed with flocculant enters the input sedimentation tank 7, it continues to accumulate, the water level continues to rise, and automatically stratifies through flocculation, impurities sink, and the degraded water rises; if the output pipe 701 is directly emptied, the gate valve 704 is opened. When the water level rises, it enters the adjustment pipe 703 and the output pipe 701, and is discharged from the rear end of the output pipe 701 after the water level fills the output pipe 701; if the output pipe 701 is also connected to the next-level treatment equipment, the gate valve 704 is closed, the air pressure inside the sedimentation tank 7 is maintained normal, and the water is transported from the rear end of the output pipe 701 to the next-level treatment equipment; when the impurity water level inside the sedimentation tank 7 is too high, the sewage transportation is stopped, the gate valve 704 is opened, and then the ball valve 702 is opened, and the settled sewage sediment is discharged from the ball valve 702 for recycling and treatment; After the discharge is completed, the ball valve 702 is closed and the sewage can be input again for sedimentation.
