Description

Technical Field

[0001] This application relates to the field of water treatment equipment technology, specifically a dosing device and wastewater treatment system for wastewater treatment. Background Technology

[0002] Advanced environmental protection industry is an important foundational industry for national economic and social development. It is committed to the development and application of water pollution control and water resource protection technologies. In various industrial and municipal wastewater treatment processes, chemical precipitation, coagulation, disinfection, and oxidation-reduction processes are crucial. The efficient implementation of these processes depends on the precise addition of chemicals. Tablet-shaped chemical agents are widely used in wastewater treatment systems because they are easy to store, transport, and measure. Typically, the agents need to be accurately measured, transported, and crushed to increase the specific surface area before being dissolved and added to the treatment tank to mix and react with the wastewater. The degree of automation and treatment efficiency of this process directly affects whether the effluent water quality meets the standards.

[0003] However, in practical applications, existing wastewater treatment dosing devices generally use fixed dosing equipment, which can only be added at fixed points. The chemicals tend to accumulate in local areas of the tank, resulting in uneven mixing. A large amount of water circulation is required to disperse the chemicals, reducing treatment efficiency. If manual mobile equipment is used, the labor intensity is high and there are dead spots in the coverage. Secondly, existing chemical conveying and crushing devices are usually set up separately and lack effective anti-clogging and stirring mechanisms. The tablets are prone to jamming or bridging during the conveying process, resulting in unstable dosage. At the same time, the crushed chemical powder particles are prone to sticking to the pipe walls. Long-term accumulation will cause pipe blockage and affect the continuous operation of the equipment. In addition, for mobile dosing devices, due to the terrain limitations at the edge of the tank and the distribution of the equipment itself, the center of gravity is often relatively high. When moving around the tank, it is prone to tilting or swaying, which poses a safety hazard. Summary of the Invention

[0004] The purpose of this application is to overcome the shortcomings of existing wastewater treatment dosing devices, such as uneven mixing due to fixed-point dosing, easy jamming of tablets during transport, easy adhesion and blockage of pipes by crushed powder, and poor operational stability of mobile equipment.

[0005] To achieve the above objectives, this application provides the following technical solution: a dosing device for wastewater treatment, comprising a treatment tank, and further comprising:

[0006] A movable component, which is mounted at the edge of the processing pool;

[0007] A tablet storage and delivery assembly, connected to the surface of a movable assembly, for dispensing tablets in a measured quantity;

[0008] A crushing assembly is installed on the outside of the tablet storage and conveying assembly, and the output end of the crushing assembly extends into the interior of the tablet storage and conveying assembly for crushing tablets.

[0009] A dosing assembly is connected to the conveying end of a tablet storage and conveying assembly, and the bottom of the dosing assembly extends into the inner side of the treatment tank.

[0010] The moving component includes:

[0011] Two circular tracks are connected to the edge of the treatment pool, and the track surfaces are arc-shaped and connected to rail wheels, enabling the entire device to operate automatically around the treatment pool.

[0012] The frame is connected to two rail wheels via a drive system, and several counterweights are connected to the top of the frame to keep the frame's center of gravity stable.

[0013] Furthermore, the tablet storage and delivery assembly includes:

[0014] A medicine storage tank, which is connected to the end of the vehicle frame away from the counterweight;

[0015] A tubular drug delivery hood is connected to the inside of a drug storage tank via bearings. The inside of the drug delivery hood has several rows of drug-holding holes arranged in a circular array. The drug-holding holes are used to insert and deliver the drug to the next step.

[0016] Two inner plates are symmetrically arranged inside the drug delivery hood. The two ends of the inner plates are connected to the inner wall of the drug storage tank. The bottom sides of the two inner plates are arc-shaped slopes to facilitate the sliding of the tablets into the drug-holding hole.

[0017] The medicine storage tank has a delivery pipe connected to one end, a funnel connected to the other end of the delivery pipe, a connecting frame connected to the outside of the funnel, and the bottom of the connecting frame connected to the outside of the medicine storage tank. The delivery pipe is equipped with a control valve to ensure the tank's airtightness when no tablets are being added to it.

[0018] Furthermore, the tablet storage and delivery assembly also includes:

[0019] A drive motor is connected to the outside of the medicine storage tank, and the output end of the drive motor is connected to a drive gear through a coupling.

[0020] Two drive wheels are connected by a drive belt, and one of the drive wheels is connected to the drive gear at the end of the shaft away from the drive motor via a drive shaft.

[0021] The storage tank has an annular groove on its outer side, which is located at one end of the delivery hood. A sealing strip is connected inside the annular groove to ensure the airtightness of the tank. A transmission gear is provided on the outer side of one end of the delivery hood. The drive gear passes through the annular groove and meshes with the transmission gear to drive the delivery hood to rotate, ensuring that the delivery hood rotates inside the storage tank.

[0022] Furthermore, the inside of the medicine storage tank is connected to a transmission rod, and several stirring strips are connected in a circular array on the outside of the transmission rod for stirring the medicine tablets so that they can smoothly enter the medicine-holding hole;

[0023] One end of the transmission rod passes through the medicine storage tank and is connected to the shaft of another transmission wheel, ensuring that while conveying the tablets, it also drives the stirring bar to stir the tablets.

[0024] Furthermore, the compaction assembly includes:

[0025] The collection trough is connected to the top opposite sides of the two inner plates. The bottom of the collection trough is inclined to facilitate the collection of crushed tablets and their smooth sliding out.

[0026] Multiple connecting pipes, the number and diameter of which are the same as those of a row of medicine slots, and the connecting pipes are connected to the top of the collection tank;

[0027] The connecting tube is equipped with several cutting strips, which are slidably connected in an axial array inside the connecting tube for crushing and cutting the tablets.

[0028] Furthermore, a force-bearing rod is connected inside the collection tank, and several extension rods are connected to the surface of the force-bearing rod;

[0029] The sliding strip has a sliding hole at its bottom axis, and a return spring is connected to the top of the sliding hole. The top of the extension rod is slidably connected to the inside of the sliding hole and to the bottom of the return spring. This causes the tablet to break under pressure when crushed, and the sliding strip to contract downwards. Releasing and resetting generates vibration to prevent the tablet from getting stuck inside the connecting tube.

[0030] Furthermore, the compaction assembly also includes:

[0031] An extension cover is connected to the outside of the medicine storage tank and communicates with its interior. The extension cover is located directly above the connecting pipe.

[0032] A control motor is connected to one end of the extension cover;

[0033] Multiple mounting brackets are connected to each other on opposite sides via a connecting shaft.

[0034] Multiple force transmission rods, several of which are connected to one end of the mounting frame via a rotating shaft;

[0035] Multiple pressing heads are movably connected to the bottom of the force transmission rod via rotating shafts. The pressing heads are located directly above and adapted to the connecting pipe.

[0036] The output end of the control motor passes through the extension cover via a coupling and is connected to the frontmost mounting bracket, enabling the drive motor to drive multiple mounting brackets to rotate synchronously at the same time. The interior of the extension cover is connected to multiple baffles, which are located outside the force transmission rod. The bottom of the baffle is connected to a track ring, which is sleeved on the outside of the compaction head to limit the movement trajectory of the compaction head.

[0037] Furthermore, the drug delivery component includes:

[0038] The transfer chamber has a pipe at the top that passes through the medicine storage tank and is connected to the collection tank, allowing the crushed tablets to slide smoothly into the transfer chamber.

[0039] A pesticide dispenser is connected to the front end of the vehicle frame, and a pesticide dispensing chamber is provided inside the pesticide dispenser.

[0040] The dosing device is located directly below the transfer chamber. The bottom of the transfer chamber is connected to a drug delivery pipe and is interconnected with its interior. The bottom of the drug delivery pipe passes through the dosing device and is interconnected with the drug delivery chamber. A control valve is installed inside the drug delivery pipe to control the tablets from the transfer chamber into the drug delivery chamber.

[0041] Furthermore, the drug delivery assembly also includes:

[0042] A delivery fan is connected to the top of the rear end of the dosing device;

[0043] The dosing device has a docking hole at the top rear end that is connected to the dosing chamber. The output end of the dosing fan is installed inside the docking hole. The front end of the dosing chamber is tilted upward. The dosing fan uses a strong airflow to deliver the tablets that fall into the dosing chamber out through the outlet.

[0044] A wastewater treatment system comprising the following steps:

[0045] S1: First, start the drive motor. The output of the drive motor rotates, which drives the drive gear to rotate. On the one hand, the transmission teeth on the outside of the delivery hood drive the tubular delivery hood to rotate inside the storage tank. On the other hand, the transmission belt drives another transmission wheel and transmission rod to rotate, which in turn drives the agitator bars arranged in a ring on the outside of the transmission rod to continuously agitate inside the storage tank. With the guidance of the arc-shaped ramps at the bottom of the two inner plates, the tablets slide smoothly into the several rows of ring-shaped drug-holding holes in the delivery hood. When the delivery hood rotates to the top position, the tablets are released from the drug-holding holes under the action of gravity and fall into the connecting pipe of the crushing component directly below. When it is necessary to replenish the tablets, they can be quickly put into the storage tank through the funnel and the delivery pipe.

[0046] S2: Then, start the control motor to drive the mounting bracket inside the extension cover to rotate, and then drive the pressing head to move through the force transmission rod. Since there is a stop groove with a track ring fixed inside the extension cover, the pressing head makes a regular reciprocating up and down movement under the restriction of the track ring. When the pressing head moves downward, its end extends into the inside of the connecting tube, forcefully squeezing the internal cutting strip and return spring, and crushing and cutting the tablets with high intensity, breaking large tablets into granules that are suitable for dissolution.

[0047] S3: When the pressing head returns to its original position, the return spring releases its elastic force, driving the cutting strip to quickly return to its original position and generate slight vibration, which can shake off the sticky tablet particles and prevent them from clogging the connecting tube. The processed tablet particles fall into the bottom inclined collection trough and slide into the transfer chamber of the dosing component under the guidance of gravity.

[0048] S4: Control the opening of the control valve in the drug delivery pipe at the bottom of the transfer chamber, and the drug granules fall into the dosing chamber. Then, start the dosing fan, and the high-speed and powerful airflow generated enters the dosing chamber through the docking hole. Because the front end of the dosing chamber is designed to be inclined upward, the airflow carries the drug granules and accelerates towards the outlet. Under the dual action of the airflow impact force and the guide slope, the drug granules are evenly and powerfully scattered into the wastewater of the treatment pool. With the movement of the vehicle frame, a comprehensive and efficient drug dosing operation is achieved.

[0049] S5: Start the drive system installed on the frame. The drive system generates power and transmits it to the rail wheel connected to it. Since the two circular tracks are pre-connected to the edge of the treatment pool, the track surface is provided with an arc that matches the rail wheel. When the rail wheel rotates, it is guided and supported by the track, thereby driving the entire frame and other components fixed on the frame to automatically circle around the edge of the treatment pool and simultaneously perform the drug dosing operation.

[0050] S6: In this process, in order to ensure the stability of the frame during movement and prevent tilting due to the high center of gravity of the equipment or the inertia of motion, several counterweights connected to the top of the frame effectively increase the bottom counterweight and lower the overall center of gravity, so that the frame remains stable during movement along the track, thereby ensuring that the equipment can move continuously and safely around the treatment pool.

[0051] Compared with the prior art, the beneficial effects of this application are as follows:

[0052] 1. This application utilizes a tablet storage and conveying assembly, which employs a drive motor to rotate a tubular delivery hood. Combined with the continuous agitation of the stirring bar and the arc-shaped guidance of the inner plate, the tablets can automatically and smoothly slide into the medication slot, achieving continuous quantitative delivery of tablets. The rotary conveying method avoids tablet blockage, ensuring that the tablets can accurately and stably enter the next process. Furthermore, the container is kept sealed during the conveying process to prevent the tablets from getting damp, thus improving the accuracy and continuity of medication administration.

[0053] 2. This application utilizes a compaction assembly that employs a control motor to drive the compaction head in a regular reciprocating lifting motion within a track loop. Combined with a cutting strip containing an internal return spring, this assembly applies high-intensity compression and cutting to the tablets falling into the connecting pipe, efficiently breaking large tablets into easily soluble particles. Simultaneously, the vibration generated by the return spring during the compaction head's reset effectively shakes off any adhering tablet particles, preventing pipe blockage and ensuring smooth tablet processing and efficient dissolution in wastewater.

[0054] 3. This application utilizes a dosing assembly to collect crushed tablets in a transfer chamber. The high-speed airflow generated by the dosing fan forcefully throws the tablet particles from the inclined dosing chamber outlet into the wastewater of the treatment tank. This pneumatic conveying method not only accelerates the dosing speed but also uses the impact force of the airflow to evenly disperse the tablets in a wide area of ​​water, avoiding tablet accumulation and significantly improving the uniformity of the drug-liquid mixture and the efficiency and effectiveness of wastewater treatment.

[0055] 4. This application utilizes a movable component with two circular tracks fixed to the edge of the treatment pool. A drive system rotates the track wheels, allowing the vehicle to automatically circle the pool. This enables comprehensive dosing of chemicals without manual intervention, providing wide coverage. Furthermore, a counterweight at the top of the vehicle effectively increases the weight at the bottom and lowers the overall center of gravity, preventing tilting due to inertia or a high center of gravity during movement, thus ensuring stability and safety during operation.

[0069] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0070] like Figure 1-11 As shown, this application provides a technical solution: a dosing device for wastewater treatment, comprising a treatment tank 1, a moving component 2, a tablet storage and conveying component 3, a pressing component 4, and a dosing component 5. Wherein:

[0071] The moving component 2 is installed at the edge of the processing pool 1; the tablet storage and conveying component 3 is connected to the surface of the moving component 2 for conveying tablets in a measured manner.

[0072] The crushing assembly 4 is installed on the outside of the tablet storage and conveying assembly 3, and the output end of the crushing assembly 4 extends into the interior of the tablet storage and conveying assembly 3 for tablet crushing processing;

[0073] The dosing assembly 5 is connected to the conveying end of the tablet storage and conveying assembly 3, and the bottom of the dosing assembly 5 extends into the inner side of the treatment tank 1.

[0074] The moving component 2 includes two annular tracks 201 connected to the edge of the treatment pool 1, and the surface of the tracks 201 is arc-shaped and connected to rail wheels 202, so that the entire device can run automatically around the treatment pool 1.

[0075] The frame 203 is connected to two rail wheels 202 via a drive system. Several counterweights 204 are connected to the top of the frame 203 to keep the center of gravity of the frame 203 stable.

[0076] By activating the drive system, the rail wheels 202 rotate on the track 201, thereby causing the entire frame 203 and other components on it to automatically circle around the edge of the treatment pool 1. This enables all-around dosing of chemicals into the treatment pool 1, avoiding blind spots and inconvenience caused by manual movement. At the same time, the several counterweights 204 connected to the top of the frame 203 can effectively increase the weight at the bottom and lower the overall center of gravity, preventing the equipment from tilting due to inertia or a high center of gravity during movement, thus ensuring that the dosing operation is continuous, safe, and stable.

[0077] As a preferred implementation method in this case, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the tablet storage and conveying assembly 3 includes a storage tank 301, which is connected to the end of the frame 203 away from the counterweight 204. A tubular conveying cover 302 is connected to the inside of the storage tank 301 via bearings. The inside of the conveying cover 302 has several rows of drug-holding holes 303, which are arranged in a circular array inside the conveying cover 302. The drug-holding holes 303 are used to insert tablets into the next conveying step. Two inner plates 304 are symmetrically arranged inside the conveying cover 302, with their ends separated. The two inner plates 304 are not connected to the inner wall of the medicine storage tank 301. The bottom sides of the two inner plates 304 are curved slopes to facilitate the sliding of the tablets into the medicine-holding hole 303. One end of the medicine storage tank 301 is connected to a delivery pipe 305. The other end of the delivery pipe 305 is connected to a funnel 306. A connecting frame 307 is connected to the outside of the funnel 306. The bottom of the connecting frame 307 is connected to the outside of the medicine storage tank 301. The delivery pipe 305 is equipped with a control valve to ensure its sealing when no tablets are being fed into the medicine storage tank 301.

[0078] The tablets are guided smoothly into the rotating drug delivery hood 302 and the drug-holding hole 303 by the arc-shaped ramps at the bottom of the two inner plates 304 inside the drug storage tank 301. This realizes the automatic, continuous and quantitative delivery of tablets, avoiding tablet blockage. The combination of delivery pipe 305 and funnel 306 facilitates tablet replenishment, while the control valve ensures the tank is sealed when no medication is being delivered, effectively preventing tablets from getting damp or leaking, and ensuring the accuracy and stability of the medication delivery process.

[0079] The pill storage and delivery assembly 3 also includes a drive motor 308, which is connected to the outside of the storage tank 301. The output end of the drive motor 308 is connected to a drive gear 309 via a coupling. Two drive wheels 313 are connected by a drive belt. One of the drive wheels 313 is connected to the shaft of the drive gear 309 away from the drive motor 308 via a drive shaft. An annular groove is provided on the outside of the storage tank 301, located at one end of the delivery cover 302. A sealing strip is connected inside the annular groove to ensure the sealing of the tank. The delivery cover 302 has an outer opening at one end. A transmission gear 310 is provided, and a drive gear 309 passes through an annular groove and meshes with the transmission gear 310, driving the medicine delivery cover 302 to rotate, ensuring that the medicine delivery cover 302 rotates inside the medicine storage tank 301. A transmission rod 311 is connected inside the medicine storage tank 301, and several stirring strips 312 are connected in an annular array on the outside of the transmission rod 311 for stirring the tablets, so that they can smoothly enter the medicine blocking hole 303. One end of the transmission rod 311 passes through the medicine storage tank 301 and is connected to the shaft of another transmission wheel 313, ensuring that while delivering the tablets, the stirring strips 312 are driven to stir the tablets.

[0080] By starting the drive motor 308 to drive the drive gear 309 to rotate, the transmission gear 310 drives the drug delivery cover 302 to rotate inside the drug storage tank 301 to deliver the tablets. On the other hand, the transmission belt drives the transmission wheel 313 and transmission rod 311 to rotate, so that the stirring bar 312 continuously stirs the tablets in the tank, effectively preventing tablet bridging or blockage, and ensuring that the tablets slide smoothly into the drug blocking hole 303. The sealing strip in the annular groove ensures the sealing of the tank, thereby realizing the synchronous and efficient operation of tablet delivery and stirring, and improving the stability and continuity of drug delivery.

[0081] As an optional implementation method in this case, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the crushing assembly 4 includes a collection trough 401, which is connected to the top opposite sides of two inner plates 304. The bottom of the collection trough 401 is inclined to facilitate the collection and smooth sliding out of the crushed tablets. Multiple connecting pipes 402 are connected to the top of the collection trough 401. Each connecting pipe 402 has several cutting strips 403 installed inside it. These cutting strips 403 are slidably connected in an axial array inside the connecting pipe 402 for crushing and cutting the tablets. The inner... The part is connected to a force-bearing rod 404, and several extension rods 405 are connected to the surface of the force-bearing rod 404. A sliding hole 406 is opened at the bottom axis of the cutting strip 403. A return spring 407 is connected to the top of the inside of the sliding hole 406. The tops of the extension rods 405 are slidably connected to the inside of the sliding hole 406 and connected to the bottom of the return spring 407, so that the tablet is crushed by force when crushed, the cutting strip 403 retracts downward, and the release and reset generates vibration to prevent the tablet from getting stuck inside the connecting tube 402.

[0082] After the tablets fall into the connecting pipe 402, they are forcefully crushed by the squeezing of the cutting strip 403. The extension rod 405 pushes the cutting strip 403 downward and compresses the return spring 407. When the pressure is released, the return spring 407 drives the cutting strip 403 to quickly return to its original position and generate slight vibration. This not only efficiently crushes large tablets into easily soluble particles, but also effectively shakes off tablets adhering to the pipe wall to prevent blockage. Combined with the inclined collection trough 401 at the bottom, the crushed tablets slide out smoothly, ensuring the efficiency of subsequent dissolution processing and the smooth operation of the equipment.

[0083] Specifically, the compaction assembly 4 also includes an extension cover 408, which is connected to the outside of the medicine storage tank 301 and communicates with its interior. The extension cover 408 is located directly above the connecting pipe 402. A control motor 409 is connected to one end of the extension cover 408. Multiple mounting brackets 410 are connected to each other on opposite sides via connecting shafts. Multiple force transmission rods 411 are respectively connected to one end of the interior of the mounting brackets 410 via rotating shafts. Multiple compaction heads 412 are respectively movably connected to the bottom of the force transmission rods 411 via rotating shafts. The compaction heads 412 are located at the connecting pipe 402. The control motor 409 is located directly above and adapted to the extension cover 408 via a coupling and is connected to the frontmost mounting bracket 410, enabling the control motor 409 to drive multiple mounting brackets 410 to rotate synchronously at the same time. The interior of the extension cover 408 is connected to multiple baffles 413, which are located outside the force transmission rod 411. The bottom of the baffles 413 is connected to a track ring 414, which is sleeved on the outside of the pressing head 412 to limit the movement trajectory of the pressing head 412.

[0084] By controlling the motor 409 to drive the mounting frame 410 to rotate, and then driving the pressing head 412 to move through the force transmission rod 411, under the restriction of the trajectory ring 414, the pressing head 412 can perform regular reciprocating lifting and lowering motion, realizing high-frequency and automated pressing and cutting of the tablets in the connecting tube 402, ensuring that the tablets are uniformly crushed into small particles, and improving the efficiency and quality of tablet processing.

[0085] As an optional implementation method in this case, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 11 As shown, the dosing assembly 5 includes a transfer chamber 501. The top of the transfer chamber 501 is connected to the storage tank 301 via a pipe, and is also connected to the collection trough 401, allowing the crushed tablets to slide smoothly into the transfer chamber 501. A dosing device 502 is connected to the front end of the frame 203. The dosing device 502 has a dosing compartment 506 inside, located directly below the transfer chamber 501. The bottom of the transfer chamber 501 is connected to a delivery pipe 503, which is also connected to the interior of the transfer chamber 501. The bottom of the delivery pipe 503 passes through the dosing device 502 and is connected to the dosing compartment 506. The delivery tube 503 is equipped with a control valve to control the tablets to fall from the transfer chamber 501 into the dosing chamber 506. The dosing assembly 5 also includes a dosing blower 504, which is connected to the top of the rear end of the dosing device 502. The top of the rear end of the dosing device 502 has a docking hole 505 that communicates with the dosing chamber 506. The output end of the dosing blower 504 is installed inside the docking hole 505. The front end of the dosing chamber 506 is tilted upward. The dosing blower 504 uses a strong airflow to deliver the tablets that fall into the dosing chamber 506 out of the outlet.

[0086] The crushed drug granules fall into the dosing chamber 506 through the transfer chamber 501 and the dosing pipe 503. Then, the dosing fan 504 is started, and the high-speed and powerful airflow generated enters the dosing chamber 506 through the docking hole 505. Since the front end of the dosing chamber 506 is designed to be inclined upward, the airflow carries the drug granules and accelerates towards the outlet. Under the dual action of the airflow impact force and the guide slope, the drug granules are evenly and powerfully scattered into the wastewater of the treatment tank, which effectively avoids the accumulation of drug granules and realizes rapid and uniform mixing of drug solution and wastewater, significantly improving the efficiency and effect of wastewater treatment.

[0087] This application also provides a wastewater treatment system comprising the following steps:

[0088] S1: First, start the drive motor 308. The output of the drive motor 308 rotates, which drives the drive gear 309 to rotate. On the one hand, the transmission gear 310 on the outside of the drug delivery cover 302 drives the tubular drug delivery cover 302 to rotate inside the drug storage tank 301. On the other hand, the transmission belt drives another transmission wheel 313 and transmission rod 311 to rotate, which in turn drives the agitator strips 312 arranged in a ring array on the outside of the transmission rod 311 to continuously agitate inside the drug storage tank 301. With the guidance of the arc-shaped ramps at the bottom of the two inner plates 304, the tablets slide smoothly into the several rows of ring array drug-locking holes 303 of the drug delivery cover 302. When the drug delivery cover 302 rotates to the top position, the tablets are released from the drug-locking holes 303 under the action of gravity and fall into the connecting pipe 402 of the crushing component 4 directly below. When it is necessary to replenish the tablets, they can be quickly entered into the drug storage tank 301 through the funnel 306 and the conveying pipe 305.

[0089] S2: Subsequently, the control motor 409 is started, which drives the mounting bracket 410 inside the extension cover 408 to rotate, and then drives the pressing head 412 to move through the force transmission rod 411. Since the extension cover 408 has a fixed groove 413 with a track ring 414, the pressing head 412 makes a regular reciprocating up and down movement under the restriction of the track ring 414. When the pressing head 412 moves downward, its end extends into the connecting pipe 402, which forcefully squeezes the internal cutting strip 403 and the return spring 407, and performs high-intensity pressing and cutting on the tablets, breaking large tablets into granules that are suitable for dissolution.

[0090] S3: When the pressing head 412 returns to its original position, the return spring 407 releases its elastic force, drives the cutting strip 403 to return to its original position quickly and generates a slight vibration, which can shake off the sticky tablet particles and prevent them from blocking the connecting pipe 402. The processed tablet particles fall into the bottom inclined collection trough 401 and slide into the transfer chamber 501 of the drug delivery component 5 under the guidance of gravity.

[0091] S4: Control the opening of the control valve in the bottom delivery pipe 503 of the transfer chamber 501, and the tablet particles fall into the dosing chamber 506. Then, start the dosing fan 504, and the generated high-speed and powerful airflow enters the dosing chamber 506 through the docking hole 505. Since the front end of the dosing chamber 506 is designed to be inclined upward, the airflow carries the tablet particles and accelerates towards the outlet. Under the dual action of the airflow impact force and the guide slope, the tablet particles are evenly and powerfully scattered into the wastewater of the treatment pool 1. With the movement of the vehicle frame 203, a comprehensive and efficient drug dosing operation is achieved.

[0092] S5: Start the drive system installed on the frame 203. The drive system generates power and transmits it to the rail wheel 202 connected to it. Since the two circular tracks 201 are pre-connected to the edge of the treatment pool 1 and the surface of the tracks 201 is provided with an arc that matches the rail wheel 202, the rail wheel 202 is guided and supported by the tracks 201 when it rotates, thereby driving the entire frame 203 and other components fixed on the frame 203 to automatically circle around the edge of the treatment pool 1 and simultaneously perform the drug dosing operation.

[0093] S6: In this process, in order to ensure the stability of the frame 203 during movement and prevent tilting due to the high center of gravity of the equipment or the inertia of motion, several counterweights 204 connected to the top of the frame 203 effectively increase the bottom counterweight and lower the overall center of gravity, so that the frame 203 remains stable during movement along the track 201, thereby ensuring that the equipment can move continuously and safely around the treatment pool 1.

[0094] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.

4. A wastewater treatment system, characterized in that, The dosing device for wastewater treatment according to any one of claims 1-3 comprises the following steps: S1: First, start the drive motor (308). The output end of the drive motor (308) rotates, driving the drive gear (309) to rotate. On the one hand, the transmission gear (310) on the outside of the medicine delivery cover (302) drives the tubular medicine delivery cover (302) to rotate inside the medicine storage tank (301). On the other hand, the transmission belt drives another transmission wheel (313) and transmission rod (311) to rotate, thereby driving the agitator strips (312) arranged in a ring on the outside of the transmission rod (311) to rotate in the medicine storage tank (301). 1) The internal stirring is continuous, and with the guidance of the arc-shaped slope at the bottom of the two inner plates (304), the tablets are smoothly slid into the several rows of annular array of drug-holding holes (303) of the drug delivery cover (302). When the drug delivery cover (302) rotates to the top position, the tablets are released from the drug-holding holes (303) under the action of gravity and fall into the connecting pipe (402) of the pressing and crushing assembly (4) directly below. When it is necessary to replenish the tablets, they can be quickly put into the storage tank (301) through the funnel (306) and the delivery pipe (305). S2: Subsequently, the control motor (409) is started, which drives the mounting bracket (410) inside the extension cover (408) to rotate, and then drives the pressing head (412) to move through the force transmission rod (411). Since the extension cover (408) has a fixed groove (413) with a track ring (414) inside, the pressing head (412) makes regular reciprocating up and down motion under the restriction of the track ring (414). When the pressing head (412) moves downward, its end extends into the inside of the connecting pipe (402), and forcefully squeezes the internal cutting strip (403) and return spring (407) to perform high-intensity pressing and cutting of the tablet, breaking the large tablet into granules that are suitable for dissolution. S3: When the pressing head (412) returns to its original position, the return spring (407) releases its elastic force, driving the cutting strip (403) to quickly return to its original position and generate slight vibration, which can shake off the sticky tablet particles and prevent them from blocking the connecting pipe (402). The processed tablet particles fall into the bottom inclined collection trough (401) and slide into the transfer chamber (501) of the drug delivery component (5) under the guidance of gravity. S4: Control the opening of the control valve in the bottom delivery pipe (503) of the transfer chamber (501), and the tablet particles fall into the dosing chamber (506). Then start the dosing blower (504), and the generated high-speed and powerful airflow enters the dosing chamber (506) through the docking hole (505). Since the front end of the dosing chamber (506) is designed to be inclined upward, the airflow carries the tablet particles to accelerate towards the outlet. Under the dual action of the airflow impact force and the guide slope, the tablet particles are evenly and powerfully scattered into the wastewater of the treatment pool (1). With the movement of the vehicle frame (203), the all-round and efficient drug dosing operation is realized. S5: Start the drive system installed on the frame (203). The drive system generates power and transmits it to the rail wheel (202) connected to it. Since the two circular tracks (201) are pre-connected to the edge of the treatment pool (1), the surface of the track (201) is provided with an arc that matches the rail wheel (202). When the rail wheel (202) rotates, it is guided and supported by the track (201), thereby driving the entire frame (203) and other components fixed on the frame (203) to automatically circle around the edge of the treatment pool (1) and simultaneously perform drug dosing operation. S6: In this process, in order to ensure the stability of the frame (203) during movement and prevent tilting due to the high center of gravity of the equipment or the inertia of movement, several counterweights (204) connected to the top of the frame (203) effectively increase the bottom counterweight and lower the overall center of gravity, so that the frame (203) remains stable during movement along the track (201), thereby ensuring that the equipment can move continuously and safely around the treatment pool (1).
