Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a zero-discharge device for iron phosphate wastewater. Background Technology

[0002] The treatment of ferric phosphate wastewater is a complex and important process, mainly because the wastewater contains high concentrations of harmful substances such as ammonia nitrogen, manganese ions, sulfate, magnesium ions and total phosphorus, and has a low pH value. For the treatment of ferric phosphate wastewater, a variety of methods, including physical, chemical and biological methods, are mainly used to achieve the discharge of wastewater in compliance with standards or to make it available for resource utilization.

[0003] Existing methods for treating phosphoric acid wastewater involve using lime slurry precipitation to remove phosphate and sulfate ions. However, the lime slurry is often transported to the wastewater tank via a single pipeline. This method not only fails to ensure sufficient contact between the wastewater and the lime slurry, thus affecting the precipitation rate, but also results in the formation of flocculent precipitates within the tank after the reaction. This flocculent precipitate cannot be quickly extracted to separate the precipitate from the reacting water, ultimately impacting the overall wastewater treatment efficiency of the tank. Therefore, a new technical solution is needed to address this issue. Summary of the Invention

[0004] The purpose of this invention is to provide a zero-discharge device for ferric phosphate wastewater, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a zero-discharge device for iron phosphate wastewater, comprising a wastewater frame, wherein hollow frames are fixedly installed on both ends of the top outer surface of the wastewater frame, a connecting plate is slidably installed on the top surface of each hollow frame, and a fixing plate is horizontally fixedly installed between the tops of two sets of connecting plates.

[0006] A liquid extraction tube is movably provided at the bottom of the fixed plate, and a pumping mechanism is provided at the top of the fixed plate, with the pumping mechanism and the top of the liquid extraction tube being fixedly connected.

[0007] Each of the hollow frames is equipped with a transmission mechanism, and the transmission mechanism is connected to the bottom of the connecting plate.

[0008] A rotating mechanism is provided on the side of the liquid extraction tube, and the rotating mechanism is connected to the side of the filter screen plate via a transmission.

[0009] By adopting the above technical solution, the lime slurry accumulated inside the storage box can be evenly discharged into the wastewater box through the transmission connection of the transmission mechanism. This allows the lime slurry and wastewater to fully contact and react, thereby increasing the reaction rate. At the same time, it allows the bottom of the feed hood to be in contact with the wastewater after sedimentation and stratification for timely and rapid extraction, thus improving the efficiency of wastewater sedimentation treatment.

[0010] In a preferred embodiment of the present invention, the pumping mechanism includes a corrugated pipe and a bidirectional pump. The corrugated pipe is vertically fixedly connected to the middle of the top of the pumping pipe. A fixed pipe is vertically fixedly installed inside the middle of the fixed plate, and the bottom of the fixed pipe is fixedly connected to the top of the corrugated pipe. Connecting pipes are horizontally fixedly connected to both ends of the side of the fixed pipe. A bidirectional pump is fixedly installed on both sides of the top of the fixed plate, and the side of the connecting pipe is fixedly connected to the bidirectional pump. A conveying pipe is fixedly connected to the side of the bidirectional pump. A feed hood is fixedly connected to the bottom of the pumping pipe, and the number of feed hoods is several sets.

[0011] By adopting the above technical solution, the liquid extraction pipe and the fixed pipe are connected through a corrugated pipe. Combined with the bidirectional pumping operation, the wastewater and lime slurry after sedimentation and stratification can be extracted and discharged for treatment, thereby improving the efficiency of wastewater sedimentation reaction treatment.

[0012] In a preferred embodiment of the present invention, storage frames are fixedly installed on both sides of the top of the fixed plate, and a discharge pipe is fixedly connected to the side of each storage frame. The side of the conveying pipe and the side of the storage pipe are fixedly connected. Electric push rods are fixedly installed on both sides of the top of the fixed plate. Fixed sleeves are fixedly sleeved on both ends of the side of the liquid extraction pipe, and the bottom of the electric push rod drive shaft is fixedly connected to the top outer surface of the fixed sleeve through a coupling.

[0013] By adopting the above technical solution, the operation of the electric actuator can provide the corresponding vertical pushing and pulling force to the liquid extraction pipe, adjust the vertical position of the feed hood, and realize the normal use of wastewater extraction and lime slurry discharge.

[0014] In a preferred embodiment of the present invention, the transmission mechanism includes a rotating lead screw. Each hollow frame has a rotating lead screw rotatably mounted inside it via a bearing. A transmission sleeve is movably sleeved on the outer surface of each rotating lead screw. A transmission block is fixedly mounted on the top outer surface of each transmission sleeve. The transmission block is slidably inserted into the top of the hollow frame. The top of the transmission block and the bottom surface of the connecting plate are fixedly connected.

[0015] By adopting the above technical solution, the rotation of the transmission sleeve by the rotating screw and the connection of the transmission block can drive the liquid extraction pipe and the feed hood to move horizontally synchronously. This allows the feed hood to move horizontally at the top of the wastewater frame, thus fully extracting and discharging lime slurry and wastewater to different positions inside the wastewater frame, improving the reaction and extraction rate of wastewater.

[0016] In a preferred embodiment of the present invention, a servo motor is fixedly installed on the outer surface of each hollow frame, and the side of the servo motor drive shaft is fixedly connected to the outside of the double-acting screw through a coupling. A limit groove is opened on the top of each hollow frame, and the transmission block is slidably inserted into the limit groove.

[0017] By adopting the above technical solution, the power required for the rotation of the bidirectional lead screw can be provided through the structural function of the servo motor.

[0018] In a preferred embodiment of the present invention, the rotating mechanism includes a transmission rod and a transmission plate. Support plates are fixedly installed on both ends of the side surface of the liquid extraction tube. The transmission rod is rotatably installed between the two sets of support plates via bearings. The transmission plates are fixedly sleeved on both ends of the outer side of the transmission rod, and the side of the transmission plate is fixedly connected to the outer side of the filter screen plate.

[0019] By adopting the above technical solution, the transmission plate and the filter screen are connected by a transmission rod, and the position of the filter screen can be adjusted by driving rotation, which facilitates the filtration of solid impurities while simultaneously turning it over for cleaning.

[0020] In a preferred embodiment of the present invention, a rotating motor is fixedly installed on the side surface of the support plate, and the side of the rotating motor drive shaft is fixedly connected to the side of the drive rod through a coupling.

[0021] By adopting the above technical solution, the power required for the rotation of the transmission rod and the filter screen can be provided by the structure of the rotating motor, thereby facilitating the cleaning of the material accumulated on the surface of the filter screen.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. This invention features a horizontally sliding connecting plate and a fixing plate on the top outer side of the wastewater frame. When the connecting plate and fixing plate move synchronously with the top-mounted pumping mechanism on the surface of the wastewater frame, the pumping mechanism, equipped with a bidirectional pump, operates. The corrugated pipe connects the suction pipe and the connecting pipe, providing suction and discharge forces to the suction pipe. The electric actuator provides vertical pushing and pulling forces to the suction pipe, allowing for vertical adjustment of the suction position. Simultaneously, the bidirectional screw drives the rotation of the transmission sleeve, adjusting the horizontal position of the suction pipe and the feed hood. This facilitates the even discharge of lime slurry accumulated inside the storage frame into the wastewater frame, ensuring sufficient contact and reaction between the lime slurry and the wastewater, thus increasing the reaction rate. Simultaneously, the bottom of the feed hood adheres to the sedimented and stratified wastewater for timely and rapid extraction, improving the efficiency of wastewater sedimentation treatment.

[0024] 2. By installing a rotatable filter screen on the side of the extraction pipe, when the extraction pipe is driven to move horizontally to spray and discharge lime slurry evenly, the filter screen can move horizontally inside the wastewater frame synchronously, performing preliminary filtration and impurity removal on the wastewater inside the wastewater frame. Subsequently, combined with the operation of the rotating motor, the filter screen can be rotated and laid flat, making it convenient for the operator to clean the debris accumulated on the surface of the filter screen.

[0035] In an optional embodiment, storage frames 26 are fixedly installed on both sides of the top of the fixed plate 22. Each storage frame 26 is fixedly connected to a discharge pipe 32 on its side. The side of the conveying pipe 29 is fixedly connected to the side of the storage pipe. Electric push rods 31 are fixedly installed on both sides of the top of the fixed plate 22. Fixed sleeves 3 are fixedly sleeved on both ends of the side of the liquid extraction pipe 23. The bottom of the drive shaft of the electric push rod 31 is fixedly connected to the outer top surface of the fixed sleeve 3 through a coupling.

[0036] In an optional embodiment, each hollow frame 2 is provided with a transmission mechanism inside, and the transmission mechanism is connected to the bottom of the connecting plate 21. The transmission mechanism includes a rotating lead screw 4. Each hollow frame 2 is rotatably mounted with a rotating lead screw 4 via a bearing. A transmission sleeve 41 is movably sleeved on the outer surface of each rotating lead screw 4. A transmission block 42 is fixedly mounted on the top outer surface of each transmission sleeve 41. The transmission block 42 is slidably inserted into the top of the hollow frame 2. The top of the transmission block 42 is fixedly connected to the bottom surface of the connecting plate 21. A servo motor 44 is fixedly mounted on the outer surface of each hollow frame 2. The side of the transmission shaft of the servo motor 44 is fixedly connected to the outer side of the bidirectional lead screw via a coupling. A limit groove 43 is provided on the top of each hollow frame 2, and the transmission block 42 is slidably inserted into the limit groove 43.

[0037] In an optional embodiment, a rotating mechanism is provided on the side of the liquid extraction tube 23, and the rotating mechanism is connected to the side of the filter screen plate 53 via a transmission mechanism. The rotating mechanism includes a transmission rod 51 and a transmission plate 52. Support plates 5 are fixedly installed on both ends of the side of the liquid extraction tube 23. The transmission rod 51 is rotatably installed between the two sets of support plates 5 via bearings. The transmission plates 52 are fixedly sleeved on both ends of the outer side of the transmission rod 51, and the side of the transmission plate 52 is fixedly connected to the outer side of the filter screen plate 53. A rotating motor 54 is fixedly installed on the side of the support plate 5, and the side of the transmission shaft of the rotating motor 54 is fixedly connected to the side of the transmission rod 51 via a coupling.

[0038] During operation, wastewater is injected into the wastewater frame 1, followed by the pouring of lime slurry required for the reaction into the storage frame 26. Then, the electric actuator 31 is activated via an external control switch, causing the suction pipe 23 to move vertically until the discharge hood moves close to the wastewater surface. The corrugated pipe 24 then connects the suction pipe 23 and the fixed pipe 25. The bidirectional pump 28 is then activated, simultaneously transporting the lime slurry stored in the storage frame 26 into the suction pipe 23. Simultaneously, the servo motor 44 is activated, causing the rotating screw 4 to rotate within the hollow frame 2. Combined with the guiding sliding action of the limit groove 43 on the transmission block 42, the transmission sleeve 41 moves horizontally within the hollow frame 2, thereby causing the connecting plate 21, the fixed plate 22, and the suction pipe 23 at their bottom to move horizontally within the wastewater frame 1, allowing the lime slurry to be discharged. After being evenly conveyed and sprayed onto the surface of the ferric phosphate wastewater accumulated inside the wastewater frame 1, the lime slurry can fully contact the wastewater and undergo a sedimentation reaction. At the same time, the filter screen 53 moves horizontally inside the wastewater frame 1 to filter and remove solid impurities from the wastewater. When the filter screen is close to the inside of the wastewater frame 1, the rotating motor 54 is started, causing it to rotate and drive the transmission rod 51 and the filter screen 53 to rotate upwards. This allows the filter screen 53 to rotate and rise to the top of the wastewater frame 1, making it convenient for the operator to clean the solid impurities accumulated on its surface. After the lime slurry has fully reacted and precipitated with the wastewater, the bidirectional pump 28 is started to reverse the pumping operation, extracting the precipitated and stratified wastewater and transporting it into the storage frame 26. Then, combined with the discharge pipe 32, the wastewater is discharged and output, completing the sedimentation and stratification treatment of the ferric phosphate wastewater.
