Description

Technical Field

[0001] The invention relates to the technical field of sewage filtration, in particular to an environmentally friendly organic fertilizer sewage filtration device. Background Art

[0002] In agricultural production, organic fertilizers are widely used due to their positive effects on soil improvement and crop growth. However, the production process of organic fertilizers is often accompanied by the generation of a large amount of sewage, which contains high concentrations of organic matter, microorganisms, suspended particles, heavy metals and other pollutants. If they are directly discharged without effective treatment, they will have a serious impact on the environment. Therefore, it is necessary to use a filtration device to separate and filter the organic fertilizer sewage; When the organic fertilizer wastewater is transported to the filter device, the staff cannot understand the concentration of the organic fertilizer wastewater transported to the filter device in real time. It is necessary to sample part of the wastewater and use other tools for detection to understand the concentration of the organic fertilizer wastewater. Then, the filtering method of the filter device is adjusted according to the wastewater concentration. Due to the delay in the sampling and detection process, the staff cannot understand the changes in the wastewater concentration in real time, which will not only cause the filter device to be in a non-optimal state for a period of time, affecting the treatment efficiency and effect, but also because the filtering method cannot be adjusted in real time, when the wastewater concentration mutates (such as a sudden increase or decrease), the filter device will not be able to respond quickly, resulting in fluctuations in the treatment effect. This fluctuation will trigger a chain reaction in the subsequent treatment process, increasing the complexity and cost of the overall treatment.

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides an environmentally friendly organic fertilizer sewage filtering device, which has the following beneficial effects: 1. By setting up a sewage concentration detection mechanism, the staff can observe the rotor speed to judge the sewage concentration in real time during the process of transporting sewage to the inside of the centrifugal filter through the water inlet pipe, and quickly obtain the change information of sewage concentration without waiting for sampling and test results. It is convenient for the staff to adjust the working parameters of the centrifugal filter according to the actual sewage situation to keep it in the optimal state, thereby ensuring the sewage treatment efficiency and effect. Moreover, when the sewage concentration suddenly changes, observing the rotor speed can quickly discover this change and immediately adjust the filtration method to adapt to the new sewage concentration, which helps to reduce the fluctuation of sewage treatment effect, improve the stability of overall treatment, and ensure that the effluent water quality meets the standards.

[0016] 2. Through the movable plate, push plate, baffle, hollow column, extension column and spring, the chemical agent inside the liquid storage tank can be dripped into the water inlet pipe through the leakage hole opened on the leakage plate while detecting the sewage concentration, so as to dilute the sewage concentration in the water inlet pipe, which can reduce the burden of the subsequent centrifugal filter and improve its sewage treatment efficiency and stability. At the same time, the stable inlet water concentration helps to maintain the stable operation of the entire treatment system, reduce the failure rate and maintenance cost of the centrifugal filter, and increase the service life of the centrifugal filter; Among them, the lever pushes the movable plate to drive the baffle to open, so that the chemical agent drips into the water inlet pipe, which can make the chemical agent delivery time correspond to the rotation speed of the lever. When the sewage concentration is too high and the lever rotation speed slows down, the chemical agent delivery time will be longer, thereby increasing the amount of agent delivered, which helps to dilute the sewage concentration more effectively. On the contrary, when the sewage concentration is diluted and the lever rotation speed becomes faster, the chemical agent delivery time will be shortened accordingly, avoiding excessive delivery of the agent, achieving precise control, and thus helping to maintain the stability of the effluent water quality, so that it is always kept within the specified standard range, and improving the water quality compliance rate; Furthermore, by synchronizing the introduction of chemical agents with the detection of sewage concentration, chemical agents can be intermittently introduced into various sewage locations inside the water inlet pipe when different sewage concentrations are detected. This can not only mix with the sewage more effectively and increase the contact opportunity between the agent and pollutants in the sewage, thereby accelerating the chemical reaction rate and improving treatment efficiency, but intermittent introduction of chemical agents can also ensure a more even distribution of the chemical agents in the sewage, thereby increasing the contact efficiency between the chemical agents and pollutants, thereby optimizing the use efficiency of the chemical agents.

[0017] 3. By setting up the sewage mixing and dilution mechanism, when the chemical agent drops into the sewage, the stirring rod can be driven to stir and mix the sewage and the chemical agent in the water inlet pipe, which not only helps the rapid dispersion and uniform action of the chemical agent, but also avoids the local waste of the chemical agent. Therefore, the dosage of the agent can be appropriately reduced to reduce the cost under the premise of ensuring the treatment effect. Moreover, it can ensure that the suspended matter and dissolved substances in the sewage are fully mixed with the chemical agent to avoid the situation of local excessive or low concentration, thereby improving the uniformity of the treatment effect. Moreover, when the stirred, mixed and diluted sewage enters the centrifugal filter, it can ensure that the sewage reaches a relatively stable concentration range before entering the centrifugal filter, which helps the centrifugal filter to better adapt to the input of sewage of different concentrations, and can more effectively utilize the separation capacity of the centrifugal filter to improve the separation effect of sewage.

[0018] 4. Through the set pressing plate and switch, the solenoid valve connected to the water inlet pipe can be opened intermittently during the stirring and mixing process of the sewage and chemical agents inside the water inlet pipe, so that the sewage after stirring and mixing can enter the centrifugal filter. This can not only control the time and flow rate of sewage entering the centrifugal filter, ensuring that the sewage enters the next treatment stage in time after being stirred and mixed evenly, thereby optimizing the overall treatment process, but also the evenly mixed sewage is not easy to form accumulation or blockage inside the centrifugal filter during the centrifugal separation process due to the uniform distribution of particles, thereby reducing equipment failures and maintenance costs.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] An environmentally friendly organic fertilizer sewage filtering device of this embodiment, such as Figure 1 - Figure 7 As shown, it includes a centrifugal filter 1, the lower end face of the centrifugal filter 1 is fixedly connected to a sewage pipe 3, the outer surface of the centrifugal filter 1 is fixedly connected to a drainage pipe 2, the upper end of the centrifugal filter 1 is fixedly connected to a water inlet pipe 4, and also includes a sewage concentration detection mechanism and a sewage mixing and dilution mechanism. The sewage concentration detection mechanism includes a rotating shaft 504, the rotating shaft 504 is rotatably connected to the water inlet pipe 4, and the rotating shaft 504 is located inside the water inlet pipe 4. One end is fixedly connected to a rotor 513, and the sewage concentration detection mechanism can detect the sewage concentration inside the water inlet pipe 4 in real time.

[0024] In this embodiment, Figure 5As shown, the end of the rotating shaft 504 away from the rotor 513 is fixedly connected to a driving power source 502, and the lower end of the driving power source 502 is fixedly connected to a support frame 501, and the support frame 501 is fixedly connected to the outer surface of the water inlet pipe 4. When the driving motor drives the rotor 513 to rotate in the water inlet pipe 4 through the rotating shaft 504, the rotor 513 will be affected by the sewage, causing the rotation speed of the rotor 513 to change. At the same time, the rotating shaft 504 connected to the upper end of the rotor 513 will change simultaneously with the rotor 513. By observing the rotation speed of the rotating shaft 504, the staff can timely understand the concentration of the sewage inside the water inlet pipe 4 and quickly obtain the change information of the sewage concentration without waiting for the sampling and detection results. It is convenient for the staff to adjust the working parameters of the centrifugal filter 1 according to the actual situation of the sewage, so that it is always in the optimal state, thereby ensuring the sewage treatment efficiency and effect.

[0025] In this embodiment, Figure 3 and Figure 5 As shown, a button 506 is fixedly connected to the side of the support frame 501 close to the rotating shaft 504, and a display screen 514 is fixedly connected to the side of the support frame 501 away from the button 506. The display screen 514 and the button 506 are electrically connected. A lever 505 is fixedly connected to the outer surface of the rotating shaft 504. The lever 505 and the button 506 are at the same height. When the rotating shaft 504 drives the lever 505 and the button 506 to separate, and drives the lever 505 to rotate to the button 506 again, when the button 506 is pressed, the display screen 514 will display the interval time of the lever 505 pressing the button 506, so that the staff can observe the rotation speed of the rotating shaft 504.

[0026] In this embodiment, Figure 3 and Figure 6 As shown, the sewage concentration detection mechanism also includes a liquid storage tank 503, and the lower end surface of the liquid storage tank 503 is fixedly connected with an injection pipe 507, the injection pipe 507 passes through and is fixedly connected to the water inlet pipe 4, and the injection pipe 507 and the water inlet pipe 4 are communicated. The chemical agent stored in the liquid storage tank 503 can flow into the lower water inlet pipe 4 through the injection pipe 507, and mix with the sewage in the water inlet pipe 4 to dilute the sewage concentration, which can reduce the burden of the subsequent centrifugal separation filter 1 and improve its sewage treatment efficiency and stability. At the same time, the stable inlet water concentration is helpful to maintain the stable operation of the entire treatment system, reduce the failure rate and maintenance cost of the centrifugal separation filter 1, and improve the service life of the centrifugal separation filter 1.

[0027] In this embodiment, Figure 6As shown, a leak plate 516 is fixedly connected to the inside of the injection tube 507, and a leak hole 517 is opened on the leak plate 516. A baffle 508 is symmetrically attached to the lower end surface of the leak plate 516. The baffle 508 is slidably connected to the injection tube 507. When the baffle 508 slides out of the injection tube 507, it will be separated from the leak hole 517 opened on the leak plate 516. At this time, the chemical agent in the liquid storage tank 503 will leak out through the leak hole 517.

[0028] In this embodiment, Figure 3 and Figure 6 As shown, the side of the baffle 508 close to the rotating shaft 504 is rotatably connected to a push plate 509, and the two push plates 509 are rotatably connected to the side away from the baffle 508. The moving plate 510 and the shifting rod 505 are located on the same horizontal line. The moving plate 510 is fixedly connected to the side of the injection tube 507 close to the extension column 512. The outer surface of the extension column 512 is slidably connected to the hollow column 511, and the hollow column 511 is fixedly connected to the outer surface of the injection tube 507. When the shifting rod 505 shifts the moving plate 510 to move horizontally, the moving plate 510 will drive the extension column 512 to slide into the hollow column 511. , and push the push plate 509 to drive the baffle 508 to slide out from the inside of the injection tube 507, and synchronize the release of chemical agents with the detection of sewage concentration. When detecting different sewage concentrations, the chemical agents can be intermittently released into various sewage locations inside the water inlet pipe 4, which can not only mix with the sewage more effectively and increase the contact opportunity between the agent and the pollutants in the sewage, thereby accelerating the chemical reaction rate and improving the treatment efficiency, but also the intermittent release of chemical agents can ensure that the chemical agents are more evenly distributed in the sewage, improve the contact efficiency between the chemical agents and the pollutants, and thus optimize the use efficiency of the chemical agents.

[0029] In this embodiment, Figure 6 As shown, the extension column 512 is fixedly connected to one end close to the hollow column 511 with a spring 515, and the spring 515 is fixedly connected to the inner wall of the hollow column 511 at one end away from the extension column 512. When the extension column 512 is pressed and slides into the hollow column 511, the spring 515 will be squeezed. When the force on the extension column 512 disappears, the rebound force of the spring 515 can push the extension column 512 to automatically slide out of the hollow column 511.

[0030] In the prior art, due to the delay in the sampling and detection process of organic fertilizer wastewater, the staff cannot understand the changes in the sewage concentration in real time, which will not only cause the filtering device to be in a non-optimal state for a period of time, affecting the treatment efficiency and effect, but also because the filtering method cannot be adjusted in real time, when the sewage concentration suddenly changes (such as a sudden increase or decrease), the filtering device will not be able to respond quickly, resulting in fluctuations in the treatment effect. This fluctuation will trigger a chain reaction in the subsequent treatment process, increasing the complexity and cost of the overall treatment. Compared with the prior art, when the sewage is transported to the inside of the centrifugal filter 1 through the water inlet pipe 4, the staff can observe the rotation speed of the rotor 513 to judge the sewage concentration in real time, and quickly obtain the change information of the sewage concentration without waiting for the sampling and detection results, so that the staff can adjust the working parameters of the centrifugal filter 1 according to the actual situation of the sewage, so that it is always in the optimal state, thereby ensuring the sewage treatment efficiency and effect, and when the sewage concentration suddenly changes, observing the rotation speed of the rotor 513 can quickly discover this change, and immediately adjust the filtering method to adapt to the new sewage concentration, which helps to reduce the fluctuation of the sewage treatment effect, improve the stability of the overall treatment, and ensure that the effluent water quality meets the standard.

[0031] In other aspects, this embodiment also provides a sewage mixing and dilution mechanism for accelerating the mixing of chemicals and sewage, such as Figure 2 , Figure 4 and Figure 7 As shown, the sewage mixing and dilution mechanism includes symmetrically arranged drive shafts 603, which are all rotatably connected to the water inlet pipe 4. The drive shafts 603 are located inside the water inlet pipe 4 and are fixedly connected to a turntable 608 at one end. The outer surface of the turntable 608 is fixedly connected to stirring rods 609 in an annular manner and equidistantly.

[0032] In this embodiment, Figure 7 As shown, the outer surface of the driving shaft 603 is fixedly connected to a pulley 602 at one end away from the stirring rod 609, and a belt 601 is sleeved between the outer surfaces of the two pulleys 602. One of the driving shafts 603 is fixedly connected to the output end of the external driving source, and the outer surface of the belt 601 is fixedly connected to a pressing plate 604. When one of the driving shafts 603 is rotated by the external power supply, the set pulley 602 and belt 601 can drive the other driving shaft 603 to rotate synchronously, and at the same time, the pressing plate 604 connected to the outer surface of the belt 601 follows the belt 601 to move around the pulley 602.

[0033] In this embodiment, Figure 4As shown, the sewage mixing and dilution mechanism also includes a solenoid valve 605, which is fixedly connected to the water inlet pipe 4 near the centrifugal filter 1. A mounting frame 606 is fixedly connected to the upper end surface of the solenoid valve 605, and a switch 607 is fixedly connected to the upper end surface of the mounting frame 606. The switch 607 is electrically connected to the solenoid valve 605, and the switch 607 is located below the pressing plate 604. When the pressing plate 604 presses the solenoid valve 605, the solenoid valve 605 will be opened, so that the sewage can enter the centrifugal filter 1 through the water inlet pipe 4. When the solenoid valve 605 loses the downward pressure of the pressing plate 604, the solenoid valve 605 will be automatically closed to prevent the circulation of sewage inside the water inlet pipe 4.

[0034] Prior art: In the existing sewage treatment process, after the chemical agent is added into the sewage, in order to increase the mixing of the chemical agent and the sewage, a stirring device is usually added inside the filter device to stir the sewage, which not only affects the structure and performance of the filter device, for example, the stirring device interferes with the normal arrangement of the filter medium and reduces the filtration efficiency, but also the filtration system cannot operate normally during the stirring process. For example, the vortex generated by the stirring will destroy the formed flocs and affect the sewage sedimentation effect, resulting in a lower filtration efficiency of the filter device for sewage. Compared with the prior art, when the chemical agent drips into the sewage, the stirring rod 609 can be driven to stir and mix the sewage and the chemical agent in the water inlet pipe 4. , which not only helps the rapid dispersion and uniform action of chemical agents, avoids local waste of chemical agents, thereby appropriately reducing the dosage of agents and reducing costs while ensuring the treatment effect, but also ensures that the suspended matter and dissolved substances in the sewage are fully mixed with the chemical agents, avoids the situation where the local concentration is too high or too low, and improves the uniformity of the treatment effect. When the stirred and mixed diluted sewage enters the centrifugal filter 1, it ensures that the sewage reaches a relatively stable concentration range before entering the centrifugal filter 1, which helps the centrifugal filter 1 to better adapt to the input of sewage of different concentrations, and can more effectively utilize the separation capacity of the centrifugal filter 1 to improve the separation effect of sewage; Among them, by setting the pressing plate 604 and the switch 607, the solenoid valve 605 connected to the water inlet pipe 4 can be intermittently opened during the stirring and mixing process of the sewage and chemical agents inside the water inlet pipe 4, so that the stirred and mixed sewage enters the centrifugal filter 1. This can not only control the time and flow rate of the sewage entering the centrifugal filter 1, ensuring that the sewage enters the next treatment stage in time after being stirred and mixed evenly, thereby optimizing the overall treatment process, but also the evenly mixed sewage is not easy to form accumulation or blockage inside the centrifugal filter 1 during the centrifugal separation process due to the uniform distribution of particles, thereby reducing equipment failures and maintenance costs.

[0035] The working process and principle involved in the overall content of the above embodiment are as follows: When the staff needs to filter the organic fertilizer wastewater, the wastewater is first transported to the water inlet pipe 4, but the wastewater is blocked by the solenoid valve 605 and cannot flow directly into the centrifugal filter 1. In the process of the wastewater flowing into the water inlet pipe 4, the staff simultaneously turns on the driving power supply 502 to drive the rotating shaft 504 to rotate on the water inlet pipe 4, and the rotor 513 connected to the lower end of the rotating shaft 504 will rotate in the water inlet pipe 4, and the rotor 513 will be affected by the sewage concentration, causing the rotation speed of the rotor 513 to change. At this time, the rotating shaft 504 connected to the upper end of the rotor 513 will be affected synchronously, driving the lever 505 connected to the outer surface of the rotating shaft 504 to rotate and separate from the button 506 connected to the side wall of the support frame 501, and rotating one circle to press the button 506 again. The connected display screen 514 is electrically connected, so the display screen 514 will record and display the time interval of the lever 505 pressing the knob. By observing the time displayed on the display screen 514, the staff can understand the rotation speed of the rotor 513 at the lower end of the rotating shaft 504 inside the water inlet pipe 4, judge the concentration of the sewage inside the water inlet pipe 4, and quickly obtain the change information of the sewage concentration without waiting for the sampling and test results. It is convenient for the staff to adjust the working parameters of the centrifugal filter 1 according to the actual sewage situation, so that it is always in the optimal state, thereby ensuring the sewage treatment efficiency and effect. Moreover, when the sewage concentration suddenly changes, observing the rotation speed of the rotor 513 can quickly discover this change, and immediately adjust the filtering method to adapt to the new sewage concentration, which helps to reduce the fluctuation of the sewage treatment effect, improve the stability of the overall treatment, and ensure that the effluent water quality meets the standard; When the rotating shaft 504 drives the lever 505 to rotate one circle to measure the rotation speed of the rotor 513, the rotating shaft 504 will drive the lever 505 to rotate close to the moving plate 510, and as the lever 505 continues to rotate, the lever 505 will push the moving plate 510 to move in the direction of the injection tube 507, and drive the moving plate 510 away from the extension column 512 connected to the side of the lever 505 to slide into the hollow column 511, squeezing the spring 515 inside the hollow column 511. In the process of the moving plate 510 moving horizontally close to the injection tube 507, since the moving plate 510 is symmetrically connected to the push plate 509 on the side close to the hollow column 511, and the push plate 509 is connected to the baffle 508 on the side away from the moving plate 510, the moving plate 510 will push One end of the push plate 509 causes the position of the push plate 509 to change, driving the baffle plate 508 connected to the other end of the push plate 509 to slide out of the injection tube 507. At this time, the chemical agent inside the liquid storage tank 503 connected to the upper end of the injection tube 507 will drip through the leakage hole 517 opened on the leakage plate 516, and pass through the injection tube 507 to flow into the water inlet pipe 4, and mix with the sewage in the water inlet pipe 4 to dilute the concentration of the sewage in the water inlet pipe 4, which can reduce the burden of the subsequent centrifugal separation filter 1 and improve its sewage treatment efficiency and stability. At the same time, the stable inlet water concentration helps to maintain the stable operation of the entire treatment system, reduce the failure rate and maintenance cost of the centrifugal separation filter 1, and increase the service life of the centrifugal separation filter 1; As the rotating shaft 504 drives the lever 505 away from the moving plate 510, the moving plate 510, through the rebound force of the spring 515 inside the hollow column 511, pushes the extension column 512 to slide out from the inside of the hollow column 511, so that the extension column 512 moves away from the moving plate 510 connected to one end of the hollow column 511, and moves in the reverse horizontal direction away from the injection tube 507. During the reverse movement of the moving plate 510, the moving plate 510, through the provided push plate 509, pulls the baffle plate 508 to slide into the injection tube 507 again, fits under the leak plate 516, and blocks the leak hole 517 on the leak plate 516. The situation that the chemical agent drips from the leak hole 517 is prevented, so that the time for adding the chemical agent corresponds to the rotation speed of the lever 505. When the sewage concentration is too high and the rotation speed of the lever 505 slows down, the time for adding the chemical agent will be longer, thereby increasing the amount of the agent added, which helps to dilute the sewage concentration more effectively. On the contrary, when the sewage concentration is diluted and the rotation speed of the lever 505 increases, the time for adding the chemical agent will be shortened accordingly, avoiding excessive addition of the agent, achieving precise control, and thus helping to maintain the stability of the effluent water quality, so that it is always kept within the specified standard range, and improving the water quality compliance rate; By synchronizing the placement of chemical agents with the detection of sewage concentration, the chemical agents can be intermittently placed at various sewage locations inside the water inlet pipe 4 when different sewage concentrations are detected. This can not only more effectively mix with the sewage, increase the contact opportunity between the chemical agents and the pollutants in the sewage, thereby accelerating the chemical reaction rate and improving the treatment efficiency, but also the intermittent placement of chemical agents can ensure that the chemical agents are more evenly distributed in the sewage, improve the contact efficiency between the chemical agents and the pollutants, and thus optimize the use efficiency of the chemical agents; When the staff turns on the driving power supply 502 to detect the sewage concentration, they simultaneously turn on the external power supply connected to one of the driving shafts 603 to drive one of the driving shafts 603 to rotate on the water inlet pipe 4. As one of the driving shafts 603 rotates, since pulleys 602 are installed on the outer surfaces of the two driving shafts 603, and the belt 601 is sleeved between the outer surfaces of the pulleys 602, when one of the driving shafts 603 rotates, the other driving shaft 603 can be driven to rotate synchronously through the pulley 602 and the belt 601. Since the driving shafts 603 are connected to a turntable 608 at one end away from the pulley 602, and a stirring rod 609 is connected to the outer surface of the turntable 608, and the stirring rod 609 and the turntable 608 are located in the water inlet pipe 4, when the two driving shafts 603 rotate synchronously, the turntable 608 can drive the stirring. The rod 609 rotates inside the water inlet pipe 4 to stir the sewage inside the water inlet pipe 4, so that the sewage and the dripping chemical agent are fully mixed, which not only helps the rapid dispersion and uniform action of the chemical agent, but also avoids the local waste of the chemical agent, thereby appropriately reducing the dosage of the agent and reducing the cost under the premise of ensuring the treatment effect, and can ensure that the suspended matter and dissolved substances in the sewage are fully mixed with the chemical agent, avoid the situation of local concentration being too high or too low, and improve the uniformity of the treatment effect. When the stirred and mixed diluted sewage enters the centrifugal filter 1, it is ensured that the sewage reaches a relatively stable concentration range before entering the centrifugal filter 1, which helps the centrifugal filter 1 to better adapt to the input of sewage of different concentrations, and can more effectively utilize the separation capacity of the centrifugal filter 1 to improve the separation effect of sewage; When the belt 601 drives the two driving shafts 603 to rotate synchronously through the pulley 602, the pressing plate 604 connected to the outer surface of the belt 601 will follow the belt 601 and move synchronously around the outer surfaces of the two pulleys 602. After the pressing plate 604 moves one circle following the belt 601, the pressing plate 604 will press the switch 607 connected to the upper end surface of the lower mounting frame 606, and the switch 607 and the solenoid valve 605 are electrically connected to open the solenoid valve 605 installed on the water inlet pipe 4. At this time, the sewage stirred and mixed inside the water inlet pipe 4 will flow into the interior of the centrifugal filter 1 below. When the pressing plate 604 follows the movement of the belt 601 and moves away from the switch 607, the pressing force on the switch 607 will disappear, thereby closing the solenoid valve 605 and preventing subsequent unmixed sewage from entering the centrifugal filter 1. This can not only control the time and flow rate of sewage entering the centrifugal filter 1, ensuring that the sewage enters the next treatment stage in a timely manner after being evenly stirred and mixed, thereby optimizing the overall treatment process, but also during the centrifugal separation process, the evenly mixed sewage is not easy to form accumulation or blockage inside the centrifugal filter 1 due to the evenly distributed particles, thereby reducing equipment failures and maintenance costs.
