Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a polyferric sulfate feeding device for wastewater treatment. Background Technology

[0002] In modern industrial production and urban life, wastewater treatment is a crucial link in maintaining ecological balance and public health. Polyferric sulfate (PFS), as a highly efficient inorganic polymeric flocculant, is widely used in the purification of various types of wastewater due to its excellent coagulation and sedimentation properties. In particular, PFS in solution form is increasingly favored in practical applications due to its convenient addition and rapid dissolution.

[0003] However, existing polyferric sulfate solution feeding devices have some problems:

[0004] Sedimentation and coagulation issues during solution storage and transportation: Polyferric sulfate solutions, especially high-concentration PFS solutions, are prone to polymerization, sedimentation, and even coagulation of their active ingredients (such as iron ion hydrolysis products) during storage or at low temperatures. This leads to increased solution viscosity, decreased fluidity, and even the formation of difficult-to-remove precipitates at the bottom of the feeding tank. This not only clogs the conveying pipelines and pumps, affecting the continuity and accuracy of feeding, but also reduces the effective utilization rate of PFS and increases the frequency and cost of equipment cleaning and maintenance.

[0005] Uneven dispersion of flocculant after liquid addition: Although polyferric sulfate (PFS) is in solution form, if it is poured directly into wastewater, the high concentration of PFS solution may not mix quickly and evenly upon contact with the wastewater, especially in large-volume or poorly flowing wastewater tanks. This can lead to excessively high flocculant concentrations in some areas, forming large and dense flocs, while other areas suffer from insufficient flocculant and poor coagulation, affecting the overall pollutant removal efficiency.

[0006] Therefore, it is necessary to provide a new polyferric sulfate feeding device for wastewater treatment to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a polyferric sulfate feeding device for sewage treatment.

[0008] The wastewater treatment polyferric sulfate feeding device provided by this utility model includes: a base plate, a shaking plate, a feeding bucket, a moving edge-adhering mechanism, and a feeding and dispersing mechanism. Locking casters are fixedly installed at the four corners of the lower surface of the base plate, and a push handle is fixedly connected to the outer side of the base plate. The shaking plate is connected to the upper surface of the base plate via an anti-caking mechanism, and the feeding bucket is placed on the upper surface of the shaking plate. The base plate is equipped with a moving edge-adhering mechanism that moves in accordance with the wastewater tank. The upper surface of the base plate is equipped with the feeding and dispersing mechanism. The device includes a telescopic tube, a limiting ring, a fixing ring, a drive motor, a rotating shaft, and a dispersing rod. The upper surface of the base plate is fixedly connected to the limiting ring via the telescopic rod. The telescopic tube slides inside the limiting ring. One end of the telescopic tube is connected to the outlet of a water pump connected to the feeding tank via a hose. The water pump is fixedly installed at the bottom of the feeding tank. The other end of the telescopic tube is fixedly connected to the outer side of the fixing ring. The bottom end of the fixing ring is fixedly connected to a waterproof drive motor. The output end of the drive motor is fixedly connected to the rotating shaft via a coupling. The bottom end of the rotating shaft is fixedly connected to the dispersing rod.

[0009] Preferably, the anti-caking mechanism includes a spring and a vibration motor. The lower surface of the shaking plate is connected to the base plate by two symmetrically distributed springs on both sides, and the vibration motor is fixedly installed on the rear end face of the shaking plate.

[0010] Preferably, the vibrating plate has limit grooves on both sides, and a limit rod is provided in the limit groove, which is fixed to the upper surface of the base plate.

[0011] Preferably, a limiting frame is fixedly connected to the upper surface of the shaking plate, and a rotating handle with a threaded rod is threadedly connected to the outer side of the limiting frame.

[0012] Preferably, the movable edge-fitting mechanism includes an edge-fitting plate and a movable rod. The front end face of the base plate has two sliding grooves, and the movable rod is slidably connected in the sliding grooves. The upper surface of the base plate is threaded with two locking blocks, which penetrate the inner wall of the base plate and contact the movable rod.

[0013] Preferably, the inner end face of the edge plate is equipped with ball bearings.

[0014] Compared with related technologies, the polyferric sulfate feeding device for wastewater treatment provided by this utility model has the following beneficial effects:

[0015] 1. This utility model ensures that the polyferric sulfate solution is fully dispersed before entering the sewage through a feeding and dispersing mechanism, thereby achieving more uniform mixing with the sewage and better exerting the flocculant's effectiveness, solving the problem of uneven dispersion of flocculant liquid in traditional feeding methods.

[0016] 2. This utility model solves the problem of sedimentation and coagulation of polyferric sulfate solution during the feeding process through an anti-caking mechanism, ensuring the smoothness and stability of feeding. During operation, the vibrating plate is connected to the upper surface of the base plate through two symmetrically distributed springs, forming an elastic support structure. When the vibration motor starts, the periodic vibration generated by it is transmitted to the feeding bucket placed on its upper surface through the vibrating plate. This vibration can effectively mix, stir and loosen the polyferric sulfate solution in the feeding bucket, destroying the flocs or precipitates formed inside, thereby avoiding sedimentation and coagulation of the solution.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] Please see Figures 1 to 2 The present invention provides a polyferric sulfate feeding device for sewage treatment, which includes: a base plate 1, a shaking plate 2, a feeding bucket 6, a moving edge-adhering mechanism, and a feeding and dispersing mechanism.

[0023] The bottom surface of the base plate 1 is fixedly equipped with locking casters 11 at all four corners, and a push handle 10 is fixedly connected to the outer side of the base plate 1, so that the entire feeding device can be moved conveniently at the edge of the sewage tank. When the device needs to be fixed for feeding, the locking casters 11 can provide stable support to prevent the device from sliding at will, thereby improving the flexibility and safety of operation. The upper surface of the base plate 1 is connected to a shaking plate 2 through an anti-caking mechanism. A feeding bucket 6 is placed on the upper surface of the shaking plate 2. The anti-caking mechanism includes a spring 9 and a vibration motor 4. The two sides of the lower surface of the shaking plate 2 are connected to the base plate 1 through two symmetrically distributed springs 9, and a vibration motor 4 is fixedly installed on the rear end face of the shaking plate 2. Limiting grooves 8 are opened on both sides of the shaking plate 2, and limiting rods 7 are provided in the limiting grooves 8. The limiting rods 7 are fixed to the upper surface of the base plate 1.

[0024] It should be noted that this utility model solves the problem of sedimentation and coagulation of polyferric sulfate solution during the feeding process through an anti-caking mechanism, ensuring the smoothness and stability of feeding. During operation, the shaking plate 2 is connected to the upper surface of the base plate 1 through two symmetrically distributed springs 9, forming an elastic support structure. When the vibration motor 4 is started, the periodic vibration generated by it is transmitted to the feeding bucket 6 placed on its upper surface through the shaking plate 2. This vibration can effectively mix, stir and loosen the polyferric sulfate solution in the feeding bucket 6, destroy the flocs or precipitates formed inside, thereby avoiding sedimentation and coagulation of the solution.

[0025] Meanwhile, the limiting grooves 8 on both sides of the vibrating plate 2 cooperate with the limiting rods 7 fixed on the upper surface of the base plate 1 to ensure the stability of the vibrating plate 2 during vibration and limit its movement trajectory, preventing excessive displacement or detachment, and ensuring the reliable operation of the anti-caking function. Through continuous low-intensity vibration, even under long-term placement or low-temperature conditions, the polyferric sulfate solution in the feeding tank 6 can maintain good fluidity, ensuring that the feeding pipeline is not blocked, greatly improving the continuity and efficiency of feeding, and reducing the frequency of manual intervention and cleaning.

[0026] The base plate 1 is provided with a movable edge-fitting mechanism that conforms to the movement of the sewage tank. The movable edge-fitting mechanism includes an edge-fitting plate 16 and a moving rod 13. Two sliding grooves are opened on the front end face of the base plate 1. The moving rod 13 is slidably connected in the sliding grooves. Two locking blocks are threadedly connected to the upper surface of the base plate 1. The locking blocks penetrate the inner wall of the base plate 1 and contact the moving rod 13. A ball bearing 12 is installed on the inner end face of the edge-fitting plate 16.

[0027] It should be noted that the moving edge-adhering mechanism improves the positioning accuracy during the feeding process and the adaptability to different sewage tank edges. When the device moves along the edge of the sewage tank, the ball bearing 12 can gently contact the sewage tank wall, and through the rolling characteristics of the ball bearing, the frictional resistance during the movement is significantly reduced, so that the device can move smoothly and stably along the tank wall, and is not easy to get stuck or damage the tank wall, while ensuring the accuracy of the movement trajectory.

[0028] Furthermore, the upper surface of the base plate 1 is threaded with two locking blocks. These locking blocks can penetrate the inner wall of the base plate 1 and contact the moving rod 13. By rotating the locking blocks, the tightness of the contact between the locking blocks and the moving rod 13 can be adjusted, thereby locking the position of the moving rod 13. The operator can flexibly adjust the relative distance between the edge plate 16 and the base plate 1 according to the thickness of different sewage tank walls or the required tightness of the edge, and fix it by locking the blocks. This ensures that the feeding operation is carried out along the preset trajectory, greatly improving the uniformity and accuracy of feeding, and avoiding errors and labor intensity caused by manual control.

[0029] The upper surface of the base plate 1 is provided with a feeding and dispersing mechanism, which includes a telescopic tube 14, a limiting ring 15, a fixing ring 20, a drive motor 19, a rotating shaft 18, and a dispersing rod 17. The upper surface of the base plate 1 is fixedly connected to the limiting ring 15 through the telescopic rod. The telescopic tube 14 slides inside the limiting ring 15. The limiting ring 15 plays a guiding role. It is fixed to the upper surface of the base plate 1 and supported by the telescopic rod (the telescopic rod is threaded with bolts for locking), so that the telescopic tube 14 can slide smoothly and stably inside it. One end of the telescopic tube 14 is connected to the outlet end of the water pump 21 connected to the feeding tank 6 through a hose. The water pump 21 is fixedly installed at the bottom end of the feeding tank 6. The other end of the telescopic tube 14 is fixedly connected to the outer side of the fixing ring 20. The bottom end of the fixing ring 20 is fixedly connected to the waterproof drive motor 19. The output end of the drive motor 19 is fixedly connected to the rotating shaft 18 through a coupling. The bottom end of the rotating shaft 18 is fixedly connected to the dispersing rod 17.

[0030] It should be noted that the feeding and dispersing mechanism ensures that the polyferric sulfate solution is fully dispersed before entering the wastewater, thereby achieving more uniform mixing with the wastewater, better exerting the flocculant's effectiveness, and solving the problem of uneven flocculant liquid dispersion in traditional feeding methods.

[0031] During operation, one end of the telescopic pipe 14 is connected to the outlet of the water pump on the feeding tank 6, which is responsible for conveying the polyferric sulfate solution from the feeding tank 6. The telescopic pipe 14 can extend and retract in its axial direction, allowing the feeding port to be adjusted in depth according to changes in the water level of the sewage tank or feeding requirements, ensuring flexibility in the feeding position.

[0032] When the drive motor 19 is working, it drives the rotating shaft 18 to rotate at high speed, which in turn drives the dispersing rod 17 to penetrate deep into the sewage for rapid agitation. The polyferric sulfate solution discharged from the telescopic pipe 14 is rapidly decomposed by the shear force and turbulence generated by the high-speed rotating dispersing rod 17 just before entering or immediately entering the sewage. This forced underwater dispersing action can efficiently disperse high-concentration solution clumps into fine droplets or particles, and make them mix violently with the surrounding sewage. This not only effectively avoids the formation of local high-concentration areas of flocculant solution at the moment of addition, but also promotes the uniform diffusion of polyferric sulfate in a wider range of sewage, thereby fully contacting suspended solids and colloidal particles in the sewage, significantly improving the efficiency and uniformity of the flocculation reaction, and improving the sewage treatment effect.

[0033] The upper surface of the vibrating plate 2 is fixedly connected to a limiting frame 5, and the outer side of the limiting frame 5 is threadedly connected to a rotating handle 3 with a threaded rod. By rotating the rotating handle 3, the component with the threaded rod can be extended or retracted, thereby locking the feeding bucket 6 in the limiting frame 5 when needed. This not only improves the stability of the feeding bucket 6, but also enhances the adaptability of the device to feeding buckets of different sizes or shapes. It also facilitates the replacement and positioning of the feeding bucket, improving the convenience of operation and the accuracy of feeding.

[0034] In summary, this utility model provides a polyferric sulfate feeding device for sewage treatment. It can be easily moved and fixed by locking casters 11 and push handle 10 under the base plate 1. In order to solve the problem of easy sedimentation and coagulation of polyferric sulfate solution, the device is equipped with an anti-caking mechanism. The vibration motor 4 drives the shaking plate 2 and the feeding tank 6 to vibrate. With the cooperation of spring 9 and limit rod 7 and limit groove 8, the continuous fluidity of the solution is ensured and blockage is prevented.

[0035] Meanwhile, to improve the accuracy and adaptability of moving along the edge of the pool, the device is designed with a moving edge-fitting mechanism. By sliding the moving rod 13 in the groove of the base plate 1 and adjusting and fixing the locking block, combined with the edge-fitting plate 16 and the ball bearing 12, the device can move smoothly and accurately along the edge of the sewage pool.

[0036] In addition, to ensure efficient dispersion of the flocculant solution, the telescopic tube 14 in the feeding and dispersing mechanism can adjust the feeding depth, and the waterproof drive motor 19 drives the dispersing rod 17 to penetrate deep into the sewage and rotate at high speed, forcibly dispersing the solution and mixing it with the sewage, thereby improving the flocculation efficiency.

[0037] The power supply, start / stop, and speed regulation control circuits and control methods of the drive motor 19 and the vibration motor 4 involved in this utility model are all conventional technologies well known to those skilled in the art and can be implemented using existing mature electrical control schemes, and are not specifically limited here.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
