Description

Technical Field

[0001] This utility model relates to the field of wastewater phosphorus treatment technology, specifically a sealed octagonal dephosphorization filter cloth filtration device. Background Technology

[0002] An octagonal dephosphorization filter cloth filtration device is a piece of equipment used for filtration and dephosphorization. Its structure typically includes an octagonal filter chamber. The special dephosphorization filter cloth and the sealing system at the joints work by first introducing the liquid to be filtered into the octagonal filter. Indoors, filtration is performed using a filter cloth. Solid impurities such as phosphorus in the liquid are trapped on the surface of the filter cloth, and the filtrate passes through the filter cloth and enters the room. Inside the filter chamber, the filtrate is discharged from the filtrate outlet. The dephosphorization function on the filter cloth surface is achieved through chemical reaction or physical adsorption. For example... The filter cloth is specially treated to contain a substance that can chemically react with phosphorus, converting phosphorus into an insoluble substance that is trapped on the filter cloth. Alternatively, the microporous structure and surface properties of the filter cloth can be used to physically adsorb phosphorus, thereby achieving the purpose of phosphorus removal.

[0003] In traditional octagonal dephosphorization filter cloth filtration devices, the filter cloth is usually fixedly installed inside the filter box and used during the process. The filter cloth remains stationary. However, stationary dephosphorization filter cloths have many shortcomings in practical use. For example, when filtering phosphorus-containing wastewater, Complex impurities in wastewater, including various phosphorus compounds and suspended solids, will quickly accumulate on the surface of the filter cloth. Because the filter cloth is stationary, these impurities cannot be dislodged through their own movement, causing the filter cloth pores to become clogged quickly, thus reducing the filtration speed. The temperature dropped sharply, quickly stagnating the originally efficient filtration process. Meanwhile, in terms of dephosphorization efficiency, the stationary filter cloth... It is difficult to ensure sufficient contact between phosphorus in the wastewater and the dephosphorizing agents on the filter cloth. Over time, a layer of phosphorus will form on the surface of the filter cloth. The filter layer consists of impurities and captured phosphorus, making it difficult for phosphorus in newly flowing wastewater to penetrate this layer and pass through the filter. Reactions occur at deep phosphorus removal sites in the fabric, significantly reducing phosphorus removal efficiency and ultimately failing to meet increasingly stringent wastewater phosphorus discharge standards. The standard is set. Furthermore, the continuous accumulation of impurities increases the pressure on the filter cloth, especially under the influence of water pressure within the filter chamber. With continued use, the uneven stress on the filter cloth becomes increasingly severe, easily leading to fiber breakage and damage, resulting in problems with the filter cloth. The service life is therefore significantly shortened. Utility Model Content

[0004] One technical problem this application aims to solve is that the filter cloth in traditional octagonal dephosphorization filter cloth filtration devices is usually solid. Fixed and stationary dephosphorization filter cloths, installed inside the filter box and remaining stationary during use, present challenges in actual use. Numerous shortcomings.

[0005] To address the aforementioned technical problems, this application provides a sealed octagonal dephosphorization filter cloth filtration device, including... The filter box has an octagonal inner cavity in the middle, and a filter cloth frame is located in the middle of the octagonal inner cavity. A dephosphorization filter cloth is fixedly installed in the middle of the outer frame, and fixing plates are fixedly installed on the top and bottom of the outer perimeter of the filter box. Each of the fixed plates is rotatably connected to a rotating cylinder at its center. The rotating cylinder has guide rails on its surface. The filter box is shaped like a rotary drum, with multiple fixed plates at the top each housing a motor. The output of each motor is fixedly connected to the rotating drum. Slide plates are fixedly installed around the center of the filter box, and each slide plate has a cross-shaped opening in its center. The multiple cross-shaped grooves penetrate the circumference of the filter box, and the middle of each cross-shaped groove slides. A cross-shaped slider is snapped in place, and one end of each of the multiple cross-shaped sliders is fixedly connected to the perimeter of the filter cloth outer frame by screws. The other end of each of the cross sliders is slidably engaged with the guide rail on the surface of the rotating drum, and the middle of the plurality of cross sliders Springs are fixedly installed at both the top and bottom, and one end of each spring is fixedly connected to the top and bottom of the middle part of the slide plate.

[0006] In some embodiments, an octagonal inclined guide plate is snapped onto the upper part of the center of the octagonal inner cavity. The guide plate is located above the slide plate, and a slot is provided on the outer side of the upper middle part of the filter box.

[0007] In some embodiments, a flow groove is formed at the lower end of the octagonal inner cavity, and the flow groove is tapered with the upper part... The diameter is larger than the bottom.

[0008] In some embodiments, a feed pipe is fixedly connected to the middle of the lower end of the filter box, and an electromagnetic valve is fixedly installed on one side of the feed pipe.

[0009] In some embodiments, a cover plate is fixedly installed at the upper end of the filter box by screws.

[0010] In some embodiments, an insert plate is fixedly installed on the outer side of the lower middle part of the cover plate, and the insert plate is inserted into the slot.

[0011] In some embodiments, a feed pipe is fixedly connected to the middle of the upper end of the cover plate, and handles are fixedly installed on both sides of the middle of the upper end of the cover plate.

[0012] In some embodiments, a support leg is fixedly installed on the outer side of the lower middle part of the filter box.

[0013] This utility model has at least the following beneficial effects: 1. In use, the motor drives the rotating drum, causing the dephosphorization filter cloth to vibrate. In actual wastewater phosphorus filtration, the wastewater composition is complex, with phosphorus potentially existing in multiple forms, along with other impurities. The vibrating dephosphorization filter cloth prevents phosphorus and impurities from accumulating on the surface, avoiding clogging of the filter pores. This not only ensures continuous and efficient filtration but also allows wastewater to flow smoothly through the filter cloth, ensuring the dephosphorization filter cloth always functions effectively, thus improving filtration efficiency and dephosphorization effect.

[0014] 2. When this utility model is in use, the dephosphorization filter cloth can be subjected to force more evenly in all parts during the shaking process, which avoids the possibility that impurities in the sewage may concentrate in certain areas, causing the dephosphorization filter cloth in these areas to bear greater pressure and friction, and thus be more prone to damage. The shaking makes the overall force on the dephosphorization filter cloth more balanced, reducing the risk of local damage, thereby extending the overall service life of the dephosphorization filter cloth.

[0015] 3. In use, the octagonal inclined guide plate above the octagonal inner cavity guides the liquid to be filtered to flow evenly onto the filter cloth. The octagonal design allows the liquid to be more evenly dispersed on the surface of the filter cloth, avoiding situations where the flow rate is too high or too low in some areas, thereby making full use of the effective filtration area of ​​the filter cloth and further improving filtration efficiency and dephosphorization effect.

[0018] The technical solutions of the present utility model will be clearly described below with reference to the accompanying drawings of the embodiments. The complete description is provided, but it is obvious that the described embodiments are only a part of the embodiments of this utility model, and not all of them. Example. Based on the embodiments of this utility model, those skilled in the art can obtain [the following information] without making any inventive effort. All other embodiments obtained are within the scope of protection of this utility model.

[0019] Example 1: Please refer to Figures 1-5. This utility model provides a technical solution: a sealed octagonal dephosphorization filter cloth. The filtration device includes a filter box 1. An octagonal inner cavity 11 is formed in the center of the filter box 1. A filter cloth frame 2 is located in the center of the octagonal inner cavity 11. A dephosphorizing filter cloth 21 is fixedly installed in the center of the filter cloth frame 2. Fixing plates 26 are fixedly installed on the upper and lower sides of the outer perimeter of the filter box 1. A rotating cylinder 27 is rotatably connected to the center of each fixing plate 26. A guide rail 28 is formed on the surface of the rotating cylinder 27. The guide rail 28 is rotary. A motor 29 is fixedly installed above each of the upper fixing plates 26. The output end of the motor 29 is fixedly connected to the rotating cylinder 27. Slide plates 22 are fixedly installed around the center of the filter box 1. A cross groove 23 is formed in the center of each slide plate 22. The cross grooves 23 penetrate the four sides of the interior of the filter box 1. A cross slider 24 is slidably engaged in the center of each cross groove 23. One end of each cross slider 24 is connected to the filter cloth frame 21. The four sides are fixedly connected by screws. The other ends of the multiple cross sliders 24 are respectively slidably engaged with the guide rails 28 on the surface of the rotating cylinder 27. Springs 25 are fixedly installed above and below the middle of the multiple cross sliders 24. One end of the multiple springs 25 is fixedly connected to the upper and lower ends of the middle of the slide plate 22. An octagonal inclined guide plate 12 is engaged above the middle of the octagonal inner cavity 11. The octagonal inclined guide plate 12 is located above the slide plate 22.

[0020] In this embodiment, when filtering phosphorus-containing wastewater, the output shaft of motor 29 starts to rotate, and the rotation of motor 29 directly drives... The rotating drum 27 rotates synchronously, rotating in the middle of the fixed plate 26. The fixed plate 26 provides stable support for the rotating drum 27, ensuring that the rotating drum 27 can perform smooth circular motion. The surface of the rotating drum 27 is provided with a rotary guide rail 28. The guide rail 28 guides the cross slider 24 that it cooperates with to make specific reciprocating motion in the cross groove 23. As the rotating drum 27 rotates, the shape of the guide rail 28 forces the cross slider 24 to make horizontal and vertical displacements along the direction of the cross groove 23. The guide rail 28 converts the circular motion of the rotating drum 27 into the linear reciprocating motion of the cross slider 24 in the cross groove 23. Since one end of the cross slider 24 is fixedly connected to the filter cloth outer frame 2 by screws, when the cross slider 24 makes reciprocating motion in the cross groove 23, it will drive the filter cloth outer frame 2 to move together. During the movement, the spring 25 plays a role in buffering and resetting. When the cross slider 24 moves in a certain direction under the action of the guide rail 28, the spring 25 is stretched or compressed, absorbing the energy during the movement and reducing the impact and vibration on the entire device. When the guide rail 28 guides the cross slider 24 to move in the opposite direction, the elastic potential energy stored in the spring 25 is released. This helps the cross slider 24 return to its original position more smoothly, ensuring the stability and reliability of the entire transmission process. Motor 29 drives the rotating drum 27 to rotate. Utilizing the cooperation of guide rail 28 and cross slider 24, along with the buffering and resetting effect of spring 25, the vibration transmission of the dephosphorization filter cloth 21 is achieved, effectively improving the filtration effect and preventing filter cloth clogging. This allows phosphorus elements in the liquid to fully contact the filter cloth, further improving dephosphorization efficiency. Simultaneously, the octagonal inclined guide plate 12 above the octagonal inner cavity 11 guides the liquid to be filtered to flow evenly onto the filter cloth. The octagonal design allows the liquid to be more evenly dispersed on the filter cloth surface, avoiding situations where the flow rate is too high or too low in certain areas, thus fully utilizing the effective filtration area of ​​the filter cloth and further improving filtration efficiency and dephosphorization effect. The filter cloth outer frame 2 is fixedly connected to the cross slider 24 with screws. This detachable connection method makes operation simple and convenient when the filter cloth needs to be replaced or cleaned, reducing maintenance costs and time.

[0021] Example 2: As shown in Figures 1-3, a slot 17 is provided on the outer side of the upper middle part of the filter box 1, and the octagonal inner cavity 11... A flow channel 13 is provided at the lower end. The flow channel 13 is tapered and the upper diameter is larger than the lower diameter. A feed pipe 14 is fixedly connected to the middle of the lower end of the filter box 1. A solenoid valve 15 is fixedly installed on one side of the feed pipe 14. A cover plate 18 is fixedly installed at the upper end of the filter box 1 by screws. An insert plate 19 is fixedly installed on the outer side of the lower middle part of the cover plate 18. The insert plate 19 is inserted into the slot 17. A feed pipe 20 is fixedly connected to the middle of the upper end of the cover plate 18. Handles 201 are fixedly installed on both sides of the middle of the upper end of the cover plate 18. A support leg 16 is fixedly installed on the outer side of the middle of the lower end of the filter box 1.

[0022] In this embodiment, the feed pipe 20 on the cover plate 18 can introduce the liquid to be filtered into the filter box 1. The flow channel 13 at the lower end of cavity 11 adopts a conical structure with a larger diameter at the top than at the bottom. This conical structure makes the flow channel 13 wider at the top and narrower at the bottom. When filtered wastewater enters the flow channel 13, it naturally flows downwards under gravity. As the channel gradually narrows, the wastewater experiences increased constraints during flow, resulting in a faster flow velocity. This allows it to pass through the flow channel 13 more quickly and be discharged from filter box 1 via discharge pipe 14, improving wastewater discharge efficiency. An electromagnetic valve 15 installed on one side of discharge pipe 14 can precisely control wastewater discharge. Operators can determine when and how much wastewater to discharge by controlling the opening and closing time of the electromagnetic valve 15, based on the actual filtration situation. This flexible control of the discharge process improves the ease of operation and controllability of the device. The slot 17 at the upper end of filter box 1 and the insert plate 19 at the lower end of cover plate 18 are interlocked, and the cover plate 18 is fixed to filter box 1 with screws. This design effectively ensures the filter box 1... Good sealing is essential. A good seal prevents liquid leakage during filtration, avoiding pollution to the surrounding environment. This also ensures stable pressure within the filter box 1, improving filtration efficiency. The cover 18, secured by screws, allows for [further filtration]. When performing maintenance, replacing filter cloth, or cleaning impurities inside the filter box 1, the cover plate 18 can be easily disassembled and installed. Operators simply need to unscrew the screws, grasp the handle 201, and lift the cover plate 18 to open the filter box 1. This simple and convenient operation reduces maintenance costs and time. The support leg 16, fixedly installed on the outer side of the lower middle part of the filter box 1, provides stable support for the entire filtration device. The support leg 16 allows the filtration device to be placed stably on the ground, preventing shaking or tipping during operation and facilitating the smooth progress of the filtration process.

[0023] As shown in Figure 1-5, phosphorus-containing wastewater enters the octagonal inner cavity of the filter box 1 through the feed pipe 20 on the cover plate 18. 11. The feed pipe 20 can be connected to external sewage conveying equipment to achieve automated sewage feeding and ensure stable sewage delivery. Sewage flows smoothly into the filtration area. After entering the octagonal inner cavity 11, it is filtered by the dephosphorization filter cloth 21. The dephosphorization filter cloth 21 is fixed to the outer frame 2 and can intercept phosphorus and other solid impurities in the sewage. Since the outer frame 2 is slidably connected to the cross groove 23 on the slide plate 22 via the cross slider 24, and the cross slider 24 is slidably engaged with the guide rail 28 on the surface of the rotating drum 27, when the motor 29 drives the rotating drum 27 to rotate, the guide rail 28 causes the cross slider 24 to reciprocate within the cross groove 23, thereby causing the outer frame 2 and the dephosphorization filter cloth 21 to vibrate. This vibration can prevent impurities such as phosphorus from accumulating on the surface of the filter cloth, improve filtration efficiency, and also make the filtration effect more uniform. After being filtered by the dephosphorization filter cloth 21, the sewage continues to flow downward and enters the flow channel 13 at the lower end of the octagonal inner cavity 11. The flow channel 13 is designed as a conical structure with a larger diameter at the top than at the bottom. Under the action of gravity, the filtered wastewater enters the discharge pipe 14 through the bottom of the flow channel 13, and then exits the filter device from the discharge pipe 14 under the action of gravity. The solenoid valve 15 on one side of the discharge pipe 14 can control the discharge speed and time of the wastewater as needed to adapt to different sewage treatment requirements. When maintenance or cleaning of the filter device is required, the screws fixing the cover plate 18 can be unscrewed, and the cover plate 18 can be lifted by holding the handle 201 to separate the cover plate 18 from the filter box 1. At this time, it is convenient to inspect the inside of the filter box 1, clean impurities, and replace the dephosphorization filter cloth 21. The insertion and engagement of the insert plate 19 and the slot 17 ensures the sealing of the device under normal conditions and prevents sewage leakage.
