Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater utilization equipment technology, and in particular to a device for recycling wastewater from ammonium phosphate production. Background Technology
[0002] Currently, wastewater ponds from phosphate fertilizer production often contain a large amount of floating debris, such as unreacted chemicals, impurities, and microbial communities. This debris floats freely in the wastewater ponds, easily entering subsequent wastewater treatment and recycling equipment, causing pipe blockages and filter clogging, affecting the normal operation of the equipment and increasing maintenance and repair costs. Furthermore, the floating debris negatively impacts wastewater quality, leading to water quality deterioration, reducing the efficiency and effectiveness of wastewater recycling, and potentially even affecting the quality of the final phosphate fertilizer product. The treatment of surface floating debris in phosphate fertilizer production wastewater ponds mostly relies on manual dredging, which is not only inefficient and costly but also poses significant safety hazards, as personnel are prone to slipping and drowning during the dredging process. Therefore, this paper proposes a wastewater recycling device for phosphate fertilizer production to address these issues. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies, which mostly rely on manual retrieval. This method is not only inefficient and costly, but also poses significant safety hazards, such as the risk of personnel slipping and drowning during operation. Therefore, this invention proposes a device for recycling wastewater from ammonium phosphate production.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a wastewater recycling device for ammonium phosphate production, comprising a wastewater pool, a fixed plate fixedly connected to the surface of the wastewater pool, a servo motor fixedly connected to one side of the fixed plate, a lead screw fixedly connected to the output end of the servo motor, a connecting plate threadedly connected to the arc surface of the lead screw, a push plate fixedly connected to one side of the two connecting plates close to each other, two slide rails fixedly connected to the surface of the push plate, a limit block slidably connected to the inner surface of the slide rails, one side of the limit block fixedly connected to the connecting plate, two sliding grooves opened on the surface of the push plate, connecting rods slidably connected to the inner walls of the sliding grooves of the push plate, an elliptical plate fixedly connected to one end of the two connecting rods, an installation groove opened on the surface of the push plate, a sliding plate slidably connected to the inner wall of the installation groove of the push plate, a pull plate fixedly connected to one side of the sliding plate, and one side of the sliding plate fixedly connected to the elliptical plate.
[0005] The aforementioned components achieve the following effects: A servo motor drives a lead screw to rotate, causing a connecting plate threaded to the lead screw to move a push plate across the wastewater tank surface. This concentrates floating debris on the wastewater tank surface to the other side, facilitating subsequent unified cleaning and preventing it from drifting randomly and affecting the normal operation of the wastewater recycling equipment. It also prevents debris from clogging equipment pipes, filters, and other components, reducing equipment malfunctions and maintenance costs. The slide rail and limit block provide guidance and limitation for the movement of the connecting plate and push plate, ensuring the push plate moves smoothly along a straight line across the wastewater tank surface under the lead screw's influence. This prevents the push plate from shifting or wobbling during movement, ensuring precise and stable centralized cleaning of floating debris. The connecting rod slides within the push plate's groove, moving the elliptical plate, sliding plate, and pull plate. The pull plate can then be used to pull the concentrated floating debris out of the water, making it easier for workers to retrieve it.
[0006] Preferably, a plurality of partition plates are fixedly connected to the surface of the push plate, and one side of the partition plate is rounded.
[0007] The effect achieved by the above components is that the isolation plate can separate the floating objects pushed by the pusher, preventing a large number of floating objects from piling up together and overflowing the pusher's pushing range.
[0008] Preferably, the surface of the pull plate is provided with a plurality of drainage holes, and the size of the connecting rod is adapted to the size of the pull plate groove.
[0009] The effect achieved by the above components is that the drainage holes on the surface of the pull plate allow wastewater to pass through the pull plate smoothly during movement, avoiding increased movement resistance due to the pull plate blocking the flow of a large amount of wastewater, and ensuring that the pull plate can handle floating objects more easily.
[0010] Preferably, the surface of the pull plate is fixedly connected with several pointed cones, and the size of the limiting block is adapted to the size of the slide rail.
[0011] The effect achieved by the above components is that the pointed cones on the surface of the pull plate can pierce larger floating objects, such as foam clumps, to prevent them from drifting.
[0012] Preferably, a setting rod is fixedly connected to one side of the elliptical plate, and a pull block is fixedly connected to one end of the setting rod.
[0013] The effect achieved by the above components is that when manual assistance is needed to adjust the position of structures such as the pull plate, force can be applied through the pull block to move the elliptical plate, the slide plate, and the pull plate, increasing the flexibility and convenience of the device operation.
[0014] In summary, the beneficial effects of this utility model are as follows:
[0015] 1. In this utility model, the lead screw is driven to rotate by a servo motor, which causes the connecting plate threaded to the lead screw to move the push plate on the surface of the wastewater pool. This can concentrate the floating objects on the surface of the wastewater pool to the other side of the wastewater pool, making it easier to clean the floating objects uniformly in the future. This avoids the situation where the floating objects float randomly on the surface of the wastewater pool, affecting the normal operation of the wastewater recycling equipment, and prevents the floating objects from clogging the equipment pipes, filters and other components, thereby reducing equipment failure and maintenance costs.

[0021] Reference Figure 1-4As shown, this utility model provides a technical solution: a wastewater recycling device for ammonium phosphate production, including a wastewater tank 1, a fixed plate 2 fixedly connected to the surface of the wastewater tank 1, a servo motor 3 fixedly connected to one side of the fixed plate 2, a lead screw 4 fixedly connected to the output end of the servo motor 3, a connecting plate 5 threadedly connected to the arc surface of the lead screw 4, a push plate 6 fixedly connected to the side of the two connecting plates 5 that are close to each other, two slide rails 7 fixedly connected to the surface of the push plate 6, a limit block 8 slidably connected to the inner surface of the slide rail 7, and one side of the limit block 8 fixedly connected to the connecting plate 5. The surface of the push plate 6 has two grooves, and connecting rods 9 are slidably connected to the inner walls of the grooves. One end of each connecting rod 9 is fixedly connected to an elliptical plate 18. The surface of the push plate 6 has an installation groove, and a sliding plate 10 is slidably connected to the inner wall of the installation groove. A pull plate 11 is fixedly connected to one side of the sliding plate 10, and one side of the sliding plate 10 is fixedly connected to the elliptical plate 18. The slide rail 7 cooperates with the limiting block 8 to provide guidance and limit for the movement of the connecting plate 5 and the push plate 6, ensuring that the push plate 6 can move smoothly under the drive of the lead screw 4. The push plate 6 moves along a straight line on the surface of wastewater pool 1 to prevent it from shifting or shaking during movement, ensuring that the push plate 6 can accurately and stably clean up floating objects. The connecting rod 9 slides in the groove of the push plate 6, which can move the elliptical plate 18, the sliding plate 10, and the pull plate 11. The pull plate 11 can be pulled up to remove the floating objects concentrated by the push plate 6 from the water surface, making it convenient for staff to retrieve the floating objects. Several isolation plates 12 are fixedly connected to the surface of the push plate 6, and one side of the isolation plate 12 is set with a rounded corner 14. The isolation plates 12 can separate the floating objects pushed by the push plate 6, preventing a large number of floating objects from accumulating together and overflowing the pushing range of the push plate 6. Several drainage holes 13 are opened on the surface of the pull plate 11, and the size of the connecting rod 9 is adapted to the size of the groove of the pull plate 11. The drainage holes 13 on the surface of the pull plate 11 allow wastewater to pass smoothly through the pull plate 11 during movement, preventing the pull plate 11 from increasing movement resistance due to obstructing the flow of large amounts of wastewater. This ensures that the pull plate 11 can more easily handle floating objects. Several pointed cones 17 are fixedly connected to the surface of the pull plate 11, and the size of the limiting block 8 is adapted to the size of the slide rail 7. The pointed cones 17 on the surface of the pull plate 11 can pierce larger floating objects, such as foam clumps, to prevent them from drifting. A setting rod 15 is fixedly connected to one side of the elliptical plate 18, and a pulling block 16 is fixedly connected to one end of the setting rod 15. When manual adjustment of the position of the pull plate 11 and other structures is required, force can be applied through the pulling block 16 to move the elliptical plate 18, the sliding plate 10, and the pull plate 11, increasing the flexibility and convenience of the device operation.
[0022] Working principle: When it is necessary to clean the floating objects on the surface of wastewater pool 1, the servo motor 3 on the fixed plate 2 is activated. The servo motor 3 outputs power to drive the lead screw 4 to rotate. Since the lead screw 4 is connected to the connecting plate 5 by threads, the connecting plate 5 will move along the axial direction of the lead screw 4 when the lead screw 4 rotates. The push plate 6, which is fixedly connected to one side of the two connecting plates 5, also moves on the surface of wastewater pool 1. During the movement, the push plate 6 pushes the floating objects on the surface of wastewater pool 1 to the other side of wastewater pool 1 and concentrates them. During this process, the slide rail 7 fixed on the surface of the push plate 6 cooperates with the limit block 8. The limit block 8 slides in the slide rail 7, providing precise guidance and limiting for the movement of the connecting plate 5 and the push plate 6, ensuring that the push plate 6 can move smoothly along a straight line and accurately concentrate the floating objects, avoiding the push plate 6 from deviating and causing incomplete cleaning. The connecting rod 9 on the push plate 6 slides in the slide groove, which can drive the elliptical plate 18, the slide plate 10 and the pull plate 11 to move. When further processing of the collected floating debris is required, the pull plate 11 can be extended from the push plate 6 by operation. For example, the operator can apply force through the pull block 16, which drives the setting rod 15, thereby moving the elliptical plate 18. The elliptical plate 18 then moves the sliding plate 10 and the pull plate 11. After the pull plate 11 is extended, the pointed cone 17 on its surface can pierce larger floating debris, such as foam clumps, dispersing them into smaller parts for easier subsequent processing. At the same time, the drainage holes 13 on the surface of the pull plate 11 allow wastewater to pass smoothly through the pull plate 11, avoiding excessive resistance during its movement and ensuring that the pull plate 11 can easily handle the floating debris. The isolation plate 12 fixed to the surface of the push plate 6 separates the pushed floating debris, preventing a large amount of floating debris from accumulating and overflowing the pushing range of the push plate 6. One side of the isolation plate 12 is rounded 14, which reduces obstruction and impact on the floating debris, allowing it to be pushed more smoothly to the designated area.
