Technical Field
[0001] This utility model relates to the field of sedimentation tank technology, specifically to a high-efficiency quantitative phosphorus removal dosing device for sedimentation tanks. Background Technology
[0002] Sedimentation tanks are structures that remove suspended solids from water using sedimentation. They utilize natural sedimentation or coagulation to remove suspended solids. In water treatment facilities such as waterworks and sewage treatment plants, they are used to remove suspended matter such as silt, algae, and bacteria from raw water, improving water quality. In industrial production processes, they can remove suspended matter such as metal ions and organic matter from wastewater, reducing environmental pollution. In agricultural irrigation systems, they can remove suspended matter such as silt and organic matter from irrigation water, improving irrigation water quality. Horizontal flow sedimentation tanks have a rectangular plan, with the inlet and outlet located at opposite ends of the tank's length. They consist of three parts: the inlet and outlet, the water flow section, and the sludge hopper. Their advantages include simple construction, good sedimentation effect, stable performance, strong adaptability to raw water turbidity, stable treatment effect, and good sludge removal when equipped with mechanical sludge removal equipment. The disadvantage is that they require a large footprint.
[0003] When using sedimentation tanks, treatment chemicals are added to remove phosphorus. Existing dosing devices typically use nozzles for spraying, but the fixed position of the nozzles makes it difficult to increase the uniformity of the spraying and reduces their practicality. Utility Model Content
[0004] The purpose of this invention is to provide a high-efficiency quantitative phosphorus removal dosing device for sedimentation tanks, in order to solve the problem mentioned in the background art that the fixed position of the nozzle makes it difficult to increase the uniformity of spraying and dosing, thus reducing its practicality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency quantitative phosphorus removal dosing device for sedimentation tanks, comprising a supporting base frame with an embedded mounting shell on its surface. A chemical tank is fixedly connected to the bottom surface of the cavity of the mounting shell. A chemical conduit is installed through the side surface of the mounting shell. A weight sensor is fixedly connected to the bottom surface of the cavity of the chemical tank. A connecting chemical tube is installed through the upper surface of the chemical tank. A drive motor is fixedly connected to the top surface of the cavity of the mounting shell. A transmission gear is fixedly connected to the output end of the drive motor. A linkage tooth block is fixedly connected to the upper outer surface of the connecting chemical tube. The upper end of the connecting chemical tube penetrates the upper surface of the mounting shell. A supporting conduit is installed through the upper surface of the connecting chemical tube. A spraying pump is fixedly connected to the upper end of the supporting conduit. A discharge pipe is fixedly connected to the upper end of the spraying pump. A spraying mechanism is provided on the upper surface of the mounting shell. The mechanism supports the chemical nozzle through a chemical guide bracket, which facilitates the adjustment of the chemical nozzle pitch when the limiting slider moves within the groove of the adjusting guide rail.
[0006] Preferably, the medicine tank is connected to the medicine conduit, and the connecting medicine conduit and the medicine tank are rotatably connected.
[0007] With the above technical solution, the medicine conduit is connected to the medicine tank, which facilitates the direct replenishment of medicine to the medicine tank through external pipes, reducing the frequency of manual operation and improving the efficiency of medicine dosing.
[0008] Preferably, the transmission gear and the linkage gear block are meshed, and the connecting medicine tube and the mounting shell are rotatably connected.
[0009] By adopting the above technical solution, the meshing transmission of gears and tooth blocks can accurately transmit the rotational power of the drive motor to the connected drug tube, ensuring uniform rotation speed, avoiding slippage or power loss, and achieving the stability of quantitative drug dosing.
[0010] Preferably, the lower end of the supporting conduit is provided with a flow hole on its outer surface, and the supporting conduit is fixedly connected to the bottom surface of the medicine tank.
[0011] By adopting the above technical solution, the flow hole design allows the medicine in the medicine tank to directly enter the pipeline through the bottom of the support conduit, shortening the medicine transmission path, reducing flow resistance, and increasing the dosing speed.
[0012] Preferably, the spraying mechanism includes a drug guide bracket, which is installed on the inner and outer surfaces of the upper end of the drug discharge pipe. A drug nozzle is installed on the surface of the drug guide bracket, and a limit slider is installed at one end of the drug nozzle. An adjustment guide rail is fixedly connected to the upper surface of the mounting housing.
[0013] Using the above technical solution, the drug guide support supports the drug nozzle, and the movement of the limiting slider within the adjusting guide rail can drive the nozzle to adjust its pitch angle, breaking through the limitations of traditional fixed nozzles and achieving uniform drug addition in different areas of the sedimentation tank.
[0014] Preferably, the drug guide support and the drug discharge pipe are rotatably connected, the drug discharge pipe has a cavity inside, and the cavity of the drug discharge pipe is connected to the drug nozzle by a flexible hose.
[0015] Using the above technical solution, the drug guide support can rotate relative to the drug discharge pipe, so that the drug discharge pipe remains fixed when the drug nozzle is adjusted, avoiding loosening of the connection or leakage of drug caused by the overall rotation of the pipe.
[0016] Preferably, the drug delivery bracket and the drug nozzle are rotatably connected, the outer surface of the adjusting guide rail is provided with a groove, and the groove of the adjusting guide rail is wavy. The adjusting guide rail is annular, one end of the limiting slider is spherical, and the limiting slider and the adjusting guide rail are engaged.
[0017] By adopting the above technical solution, the annular wave-shaped guide rail design enables the limit slider to rotate with the drug guide bracket, and the undulation of the groove drives the nozzle to automatically pitch, thereby realizing the periodic change of the spraying angle. No additional power source is required, simplifying the mechanical structure.
[0018] Compared with the prior art, the beneficial effects of this utility model are: This high-efficiency sedimentation tank quantitative phosphorus removal dosing device:
[0019] 1. In the spraying mechanism, the chemical nozzles engage with the annular wave-shaped adjusting guide rail via a limiting slider. When the chemical guide support rotates with the connecting chemical tube, the limiting slider moves along the wave-shaped trajectory of the guide rail groove, causing the nozzles to automatically pitch up and down, achieving periodic changes in the spraying angle. This avoids the blind spots of traditional fixed nozzles and ensures uniform distribution of chemicals at different depths and areas of the sedimentation tank. The drive motor, through the meshing of the transmission gear and the linkage gear block, drives the connecting chemical tube to rotate, thereby causing the discharge pipe and the chemical guide support to rotate synchronously, achieving the circumferential motion of the chemical nozzles, covering the entire area of the sedimentation tank, and eliminating the dead angle problem of static spraying.
[0020] 2. The weight sensor installed at the bottom of the chemical tank can monitor the chemical level in real time and feed the signal back to the control system to precisely control the replenishment frequency of the chemical conduit, avoiding fluctuations in phosphorus removal efficiency due to insufficient or excessive dosage. The meshing transmission of the transmission gear and the linkage gear block has a fixed transmission ratio, ensuring that the rotation speed of the connected chemical conduit is uniform and controllable. Combined with the constant flow of the spray pump, it can achieve precise control of the dosage per unit time, meeting the phosphorus removal dosage requirements of different water qualities.
[0021] 3. The connecting tubes to the medicine tank and the mounting shell are all rotatably connected to prevent pipe twisting during rotation; the discharge pipe is connected to the medicine nozzle via a flexible hose, allowing the nozzle to swing without affecting the pipe's sealing, reducing mechanical wear and leakage risks; the guide bracket is rotatably connected to the discharge pipe, separating nozzle angle adjustment from pipe fixation, making the structure more flexible; the mounting shell integrates the medicine tank, drive motor, and other core components, with a compact layout and small footprint; the medicine conduit supports direct external replenishment, reducing manual opening operations; the locking structure of the adjustment guide rail and limit slider allows for nozzle angle calibration without complex disassembly, reducing maintenance difficulty.

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-6 This utility model provides a technical solution: a high-efficiency quantitative phosphorus removal dosing device for sedimentation tanks, comprising a supporting base frame 1, a mounting shell 2, a chemical tank 3, a chemical conduit 4, a weight sensor 5, a connecting chemical pipe 6, a drive motor 7, a transmission gear 8, a linkage gear block 9, a supporting conduit 10, a spray pump 11, a chemical discharge pipe 12, a chemical guide bracket 13, a chemical nozzle 14, an adjusting guide rail 16, and a limiting slider 15. The supporting base frame 1 has the mounting shell 2 embedded in its surface. The chemical tank 3 is fixedly connected to the bottom surface of the cavity of the mounting shell 2. The chemical conduit 4 is installed through the side surface of the mounting shell 2. A weight sensor 5 is fixedly connected to the surface. The medicine tank 3 is connected to the medicine conduit 4. The connecting medicine pipe 6 is rotatably connected to the medicine tank 3. The medicine tank 3 stores the dephosphorization medicine and is connected to the external supply pipeline through the medicine conduit 4, so that the medicine can be replenished in real time. The weight sensor 5 is fixed to the bottom of the medicine tank 3 to monitor the weight of the medicine in real time. The data is fed back to the control system to control the opening and closing of the medicine conduit 4 to maintain a constant amount of medicine. The flow hole at the lower end of the support conduit 10 is connected to the bottom of the medicine tank 3. The medicine flows into the support conduit 10 through the connecting medicine pipe 6 by gravity or the negative pressure of the spray pump 11, and then is transported to the spraying mechanism through the discharge pipe 12.
[0031] A connecting tube 6 is installed through the upper surface of the medicine tank 3. A drive motor 7 is fixedly connected to the top surface of the cavity of the mounting shell 2. A transmission gear 8 is fixedly connected to the output end of the drive motor 7. A linkage gear block 9 is fixedly connected to the upper outer surface of the connecting tube 6. The upper end of the connecting tube 6 penetrates the upper surface of the mounting shell 2. A support guide tube 10 is installed through the upper surface of the connecting tube 6. The transmission gear 8 and the linkage gear block 9 form a meshing connection. The connecting tube 6 and the mounting shell 2 form a rotatable connection. A flow hole is provided on the lower outer surface of the support guide tube 10. The support conduit 10 is fixedly connected to the bottom surface of the medicine tank 3. The drive motor 7 is fixed to the top of the mounting shell 2. After starting, it drives the transmission gear 8 to rotate. The transmission gear 8 meshes with the linkage gear block 9 and transmits power to the connecting medicine pipe 6. Since the connecting medicine pipe 6 is rotatably connected to the medicine tank 3 and the mounting shell 2, it can rotate freely around the axis. When the connecting medicine pipe 6 rotates, it drives the upper support conduit 10, spray pump 11, discharge pipe 12 and medicine guide bracket 13 to perform circular motion synchronously, so as to realize the horizontal rotation and coverage of the medicine nozzle 14.
[0032] A spray pump 11 is fixedly connected to the upper end of the support conduit 10, and a discharge pipe 12 is fixedly connected to the upper end of the spray pump 11. The spraying mechanism includes a drug guide bracket 13, which is installed on the inner and outer surfaces of the upper end of the discharge pipe 12. A drug nozzle 14 is installed on the surface of the drug guide bracket 13, and a limit slider 15 is installed at one end of the drug nozzle 14. An adjustment guide rail 16 is fixedly connected to the upper surface of the housing 2. When the drug guide bracket 13 rotates with the connecting drug pipe 6, the limit slider 15 moves along the wavy groove of the guide rail. The undulation of the groove forces the nozzle to make a pitching motion. When the slider enters the crest of the groove, the nozzle pitch angle increases, and the drug is sprayed upwards towards the sedimentation tank. When the slider slides to the trough, the nozzle pitch angle increases, and the drug is sprayed downwards towards the bottom of the sedimentation tank.
[0033] The upper surface of the housing 2 is equipped with a spraying mechanism, which supports the medicine nozzle 14 through the medicine guide bracket 13. When the limiting slider 15 moves within the groove of the adjusting guide rail 16, it drives the medicine nozzle 14 to adjust its pitch. The medicine guide bracket 13 is rotatably connected to the medicine discharge pipe 12. The medicine discharge pipe 12 has a cavity inside, and the cavity of the medicine discharge pipe 12 is connected to the medicine nozzle 14 through a hose. The outer surface of the adjusting guide rail 16 has a groove, and the groove of the adjusting guide rail 16 has a wave design. The adjusting guide rail 16 has a ring design. One end of the limiting slider 15 has a spherical design. The limiting slider 15 and the adjusting guide rail 16 form a snap-fit connection. The medicine discharge pipe 12 and the medicine nozzle 14 are connected through a hose, which allows the medicine to flow when the nozzle swings, avoiding pipe damage caused by rigid connection.
[0034] Working principle: When using this high-efficiency sedimentation tank quantitative phosphorus removal dosing device, the drive motor 7 drives the transmission gear 8 to rotate. Through meshing with the linkage gear block 9, it drives the connecting medicine pipe 6 to rotate around the axis, causing the support pipe 10, the discharge pipe 12, and the medicine guide bracket 13 installed on it to perform circular motion synchronously. The medicine in the medicine tank 3 is transported to the medicine nozzle 14 through the support pipe 10 and the discharge pipe 12. When the medicine guide bracket 13 rotates, the limiting slider 15 at one end of the medicine nozzle 14 slides along the annular wave-shaped adjusting guide rail 16 fixed on the mounting shell 2, forcing the nozzle to automatically perform pitching motion to achieve multi-angle spraying. The spray pump 11 provides power to ensure the medicine delivery pressure. The weight sensor 5 monitors the amount of medicine in the medicine tank 3 in real time. The control system adjusts the medicine pipe 4 to replenish the medicine, realizing quantitative dosing and increasing the overall practicality.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
