Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device based on wastewater treatment reagents. Background Technology

[0002] Wastewater treatment is a technological system that purifies water bodies using physical, chemical, and biological methods to meet discharge or reuse standards. Wastewater treatment devices based on wastewater treatment reagents are devices that treat wastewater using chemical methods. During the treatment process, the addition of chemical agents is a crucial step in ensuring the treatment effect.

[0003] However, in existing wastewater treatment devices based on wastewater treatment reagents, when granular or powdered solids are added, the granular reagents are prone to caking at the outlet due to gravity compression and environmental moisture when stored in the hopper for a long time, forming an "arch" structure. This prevents the reagents from falling normally, causing dosing interruptions. Furthermore, after the reagents in the upper part of the hopper have been left to stand for a long time, they are also prone to overall caking due to moisture, temperature changes, and their own gravity compaction, forming hard lumps. This prevents the reagents from falling naturally, further exacerbating the instability of dosing. Summary of the Invention

[0004] The purpose of this invention is to provide a wastewater treatment device based on wastewater treatment reagents to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wastewater treatment device based on a wastewater treatment reagent, comprising an inlet pipe and an anti-clogging component. A hopper is disposed above the inlet pipe, and the anti-clogging component is disposed inside the hopper. The anti-clogging component includes a support, and the lower part of the hopper is provided with the support. A valve column is slidably connected to the inner side of the support. A communicating cavity is provided inside the valve column, and a plug is disposed inside the communicating cavity. A valve plate is connected to the upper end of the valve column, and a communicating groove is opened inside the valve plate. A receiving groove is symmetrically arranged around the communicating groove, and a crushing rod is slidably connected to the receiving groove. A double gear is rotatably connected to the valve column below the plug, and a toothed rod is connected below the plug. A toothed ring is provided on the outside of the double gear on the valve column.

[0006] Furthermore, the connecting cavity is filled with oil above the plug, and the connecting groove is connected to the connecting cavity. The receiving groove is equidistantly distributed around the connecting groove, and the breaking rod is attached to the inner wall of the receiving groove.

[0007] Furthermore, the double gear is composed of gears of different diameters, and the small gear on the double gear meshes with the rack, the gear ring meshes with the large gear on the double gear, and the gear ring is connected to the valve stem.

[0008] Furthermore, a push rod is slidably connected to the lower part of the communicating cavity, and a ball head is connected to one side of the push rod. A pushing spring is connected to the other side of the push rod, and the push rod is connected to a toothed rod. The push rod is elastically connected to the communicating cavity through the pushing spring.

[0009] Furthermore, a shaft is rotatably connected inside the water inlet pipe, and an impeller is connected to one side of the shaft. Connecting rods are symmetrically connected to the surface of the shaft, and a scraper is connected to one end of each connecting rod.

[0010] Furthermore, the connecting rods are distributed in an equidistant spiral pattern on the shaft, and four scrapers are symmetrically distributed about the shaft, the scrapers being spiral-shaped.

[0011] Furthermore, a water channel is provided in the middle of the scraper, and a nozzle is provided on one side of the water channel. The nozzles are evenly distributed on the scraper, and the water channel does not penetrate the left end of the scraper.

[0012] Furthermore, a slot is provided on the side of the scraper that is close to the inner wall of the water inlet pipe, and a fine-adjustment spring is connected in the slot. One end of the fine-adjustment spring is connected to a scraper strip, and the scraper strip is engaged and slidably connected to the slot. The scraper strip is elastically connected to the scraper through the fine-adjustment spring.

[0013] Furthermore, a transfer box is provided on one side of the water inlet pipe, and an overflow port is provided on one side of the transfer box. A partition is provided inside the transfer box, and a cover is provided on top of the transfer box.

[0014] Furthermore, the transfer box is equipped with a drive wheel, and a transmission wheel is provided on one side of the drive wheel. A stirring rod is connected to one side of the transmission wheel via a rotating shaft, and the stirring rod is located inside the hopper. The drive wheel is connected to a shaft, and the drive wheel is located on the right side of the partition. The transmission wheel is located inside the cover.

[0015] This invention provides a wastewater treatment device based on wastewater treatment reagents, which has the following beneficial effects: During use, the reagent can be added according to the wastewater flow rate, and the reagent can be loosened and stirred to prevent the reagent from clumping due to pressure or moisture, which would cause blockage at the outlet and prevent normal dosing. After the reagent enters the wastewater, it can automatically perform preliminary mixing of the wastewater and the reagent, improving the mixing efficiency and preventing the reagent from crystallizing and adhering to the inner wall of the pipe. The inner wall of the pipe can be cleaned in time to prevent the pipe from being blocked or corroded by reagent crystals.

[0016] 1. In this invention, as the scraper moves with the shaft, it periodically lifts the valve plate to dispense the agent. As the wastewater flow increases, the frequency of the scraper actuating the ball head accelerates, thus achieving automatic adjustment of the dosage according to the wastewater flow. Furthermore, the moving valve plate vibrates the agent at the bottom of the hopper, preventing the agent from forming an arch structure at the outlet due to moisture, thus preventing blockage. The vibration frequency matches the dosing frequency, continuously disrupting the bridging tendency between agent particles. This prevents the agent from caking at the hopper outlet. In this situation, the plunger can push the crushing rod out of the receiving tank through the oil. At the same time, the rack drives the valve column to rotate inside the bracket through the double gear and gear ring, causing the valve plate to drive the crushing rod to rotate synchronously, breaking up the caking agent and preventing it from blocking the discharge port. After the caking is broken up, the push spring can drive the entire anti-blocking component, causing the valve column and valve plate to rotate, and the remaining caking blocks are sheared a second time. At the same time, the oil is drawn back to the crushing rod to prevent it from being exposed to the agent for a long time and being corroded or adhered, thus allowing the hopper to resume normal drug feeding.

[0017] 2. In use, the scraper cleans the inner wall of the inlet pipe, preventing chemical crystals from adhering to the pipe wall, corroding it, or clogging it. The connecting rod, as it moves, stirs the wastewater containing the added chemicals, thus initially mixing it and reducing the chance of crystallization within the pipe, shortening the subsequent reaction time. Simultaneously, the stirring and disturbance prevents chemical deposition at the bottom of the pipe, further reducing the probability of crystal formation. As the wastewater flows, it enters the scraper through the water channel and is sprayed onto the inner wall of the pipe through the nozzle, assisting the scraper in cleaning and preventing crystals from adhering to it. This avoids chemical crystal accumulation and blockage when the wastewater flow rate is low. Furthermore, as the wastewater flow rate increases, the flow velocity in the inlet pipe accelerates, increasing the speed at which the impeller drives the shaft. The centrifugal force on the scraper as it moves with the scraper also increases, resulting in greater pressure on the inner wall of the pipe and stronger cleaning force. This achieves the effect of faster cleaning and stirring with higher wastewater flow rates, while gentle scraping reduces wear at low flow rates.

[0018] 3. When the shaft rotates, the drive wheel and transmission wheel can drive the stirring rod to rotate synchronously, causing the stirring rod to stir the agent in the hopper. This prevents the agent from forming clumps in the hopper under the action of moisture and pressure, which would prevent the agent from being properly added. After the sewage leaves the inlet pipe, the drive wheel can block the sewage, allowing it to fall only into the right side of the partition in the transfer tank, preventing the sewage from flowing directly to the left side of the partition. This reduces the direct impact of the water flow on the sedimentation zone. After the sewage enters the transfer tank, it will first transfer on the right side of the partition, while the drive wheel can simultaneously stir the upper part of the sewage, allowing the agent to disperse and integrate into the sewage. When the sewage level exceeds the upper part of the partition, it will overflow to the left side of the partition and stand still, thereby separating and separating large particles of dirt. The clear liquid on the top can then flow out of the transfer tank through the overflow port to the subsequent treatment tank for further purification. The sediment in the transfer tank can be periodically cleaned by an external sewage pump to ensure that the sediment ratio in the transfer tank is not too high. Attached Figure Description

[0021] Please see Figures 1 to 6 The present invention provides a technical solution: a sewage treatment device based on sewage treatment reagent, including an inlet pipe 1 and an anti-clogging component 3. A hopper 2 is provided above the inlet pipe 1, and the anti-clogging component 3 is provided inside the hopper 2. The anti-clogging component 3 includes a support 301. The support 301 is provided in the lower part of the hopper 2, and a valve column 302 is slidably connected to the inner side of the support 301. A connecting cavity 303 is provided in the valve column 302, and a plug 304 is provided in the connecting cavity 303. A valve plate 305 is connected to the upper end of the valve column 302, and a connecting groove 306 is opened in the valve plate 305. A receiving groove 307 is symmetrically arranged around the connecting groove 306, and a crushing rod 308 is slidably connected in the receiving groove 307. A double gear 309 is rotatably connected to the valve column 302 below the plug 304, and a toothed rod 310 is connected below the plug 304. A toothed ring 311 is provided on the outside of the double gear 309 of the valve column 302.

[0022] Please see Figures 1 to 3 The connecting cavity 303 is filled with oil above the plug 304, and the connecting groove 306 is connected to the connecting cavity 303. The receiving groove 307 is equidistantly distributed around the connecting groove 306, and the breaking rod 308 is attached to the inner wall of the receiving groove 307. The double gear 309 is composed of gears of different diameters, and the small gear on the double gear 309 meshes with the rack 310. The gear ring 311 meshes with the large gear on the double gear 309, and the gear ring 311 is connected to the valve column 302. The lower part of the connecting cavity 303 is engaged and slidably connected to the push rod 4, and one side of the push rod 4 is connected to the ball head 5, and the other side of the push rod 4 is connected to the pushing spring 6. The push rod 4 is connected to the rack 310, and the push rod 4 is elastically connected to the connecting cavity 303 through the pushing spring 6. The specific operation is as follows: When the scraper 10 moves with the shaft 7, each time it passes under the hopper 2, it moves up and down by pushing the push rod 4 through the ball head 5. This causes the push rod 4 to slide the valve column 302 inside the bracket 301 through the pushing spring 6, lifting the valve plate 305 and releasing the valve plate 305 from the hopper 2. This allows the granular medicine contained in the hopper 2 to fall into the feed pipe, completing the medicine dispensing. As the sewage flow increases, the frequency of the scraper 10 pushing the ball head 5 increases, causing the valve column 302 to move the valve plate 305 more frequently. When the valve column 302 moves the valve plate 305, it can vibrate the medicine at the lower end of the hopper 2. When the medicine clumps at the outlet of the hopper 2, the ball head 5 drives the push rod 4 to rise while the valve plate 305 cannot rise. When the jacking spring 6 is compressed, the jacking rod 4 drives the plug 304 to move in the connecting cavity 303 via the rack 310, pressing the oil in the connecting cavity 303 into the receiving groove 307 through the connecting groove 306. This pushes the crushing rod 308 out of the receiving groove 307. At the same time, the rack 310 drives the valve 302 to rotate inside the bracket 301 via the double gear 309 and the gear ring 311, which causes the valve plate 305 to drive the crushing rod 308 to rotate synchronously. After the slab is crushed, the jacking spring 6 drives the valve 302 and the valve plate 305 to move upward, while the rack 310 and the plug 304 return to their original positions in the connecting cavity 303, causing the valve 302 and the valve plate 305 to rotate and perform secondary crushing of the agent. At the same time, the oil will also draw the crushing rod 308 back into the receiving groove 307, thus allowing the hopper 2 to resume normal drug feeding.

[0023] Please see Figures 2 to 6A shaft 7 is rotatably connected inside the water inlet pipe 1, and an impeller 8 is connected to one side of the shaft 7. Connecting rods 9 are symmetrically connected to the surface of the shaft 7, and a scraper 10 is connected to one end of each connecting rod 9. The connecting rods 9 are evenly distributed spirally on the shaft 7, and four scrapers 10 are symmetrically distributed about the shaft 7. The scrapers 10 are spiral-shaped, with a water channel 11 in the middle. A nozzle 12 is opened on one side of the water channel 11 on the scraper 10, and the nozzles 12 are evenly distributed on the scraper 10. The water channel 11 does not penetrate the left end of the scraper 10. A slot 13 is opened on the side of the scraper 10 close to the inner wall of the water inlet pipe 1, and a fine-tuning spring 14 is connected within the slot 13. One end of the fine-tuning spring 14... A scraper 15 is connected and is engaged and slidably connected with a slot 13. The scraper 15 is elastically connected to the scraper 10 through a fine-adjustment spring 14. A transfer box 16 is provided on one side of the water inlet pipe 1, and an overflow port 17 is provided on one side of the transfer box 16. A partition 18 is provided inside the transfer box 16, and a cover 19 is provided above the transfer box 16. A drive wheel 20 is provided inside the transfer box 16, and a transmission wheel 21 is provided on one side of the drive wheel 20. A stirring rod 22 is connected to one side of the transmission wheel 21 through a rotating shaft, and the stirring rod 22 is located inside the hopper 2. The drive wheel 20 is connected to the shaft 7, and the drive wheel 20 is located on the right side of the partition 18. The transmission wheel 21 is located inside the cover 19. The specific operation is as follows: During use, after sewage enters the inlet pipe 1, the impeller 8 drives the shaft 7 to rotate within the inlet pipe 1. This causes the connecting rod 9 to drive the scraper 10 to move along with the shaft 7 within the inlet pipe 1. The scraper blade 15, under the action of the fine-tuning spring 14, adheres tightly to the inner wall of the inlet pipe 1 and moves with the scraper blade 10, thus cleaning the inner wall of the inlet pipe 1. The connecting rod 9, while moving, can stir the sewage containing the added chemicals. As the sewage flows, it enters the scraper blade 10 through the water channel 11 and is sprayed onto the inner wall of the pipe through the nozzle 12. As the sewage flow rate increases, the flow velocity within the inlet pipe 1 also increases, increasing the rotation speed of the shaft 7 driven by the impeller 8. The scraper blade 15, moving with the scraper blade 10, experiences increased friction. The greater the force, the greater the pressure exerted by the scraper 15 on the inner wall of the pipe. When the shaft 7 rotates, it can drive the drive wheel 20 to rotate synchronously, thereby driving the stirring rod 22 to rotate synchronously through the transmission wheel 21. After the sewage leaves the inlet pipe 1, the drive wheel 20 can block the sewage, so that the sewage can only fall into the right side of the partition 18 in the transfer box 16. After the sewage enters the transfer box 16, it will first be transferred on the right side of the partition 18, while the drive wheel 20 can simultaneously agitate the upper part of the sewage. When the sewage level exceeds the upper end of the partition 18, it will overflow to the left side of the partition 18 and stand still, thereby separating the large particles of dirt inside. The upper clear liquid can then flow out of the transfer box 16 through the overflow port 17 to the subsequent treatment tank for further purification.

[0024] In summary, this wastewater treatment device based on wastewater treatment reagents is used by first placing the reagent into the hopper 2 and adding it periodically. After the wastewater enters the inlet pipe 1, the impeller 8 drives the shaft 7 to rotate inside the inlet pipe 1, thereby causing the connecting rod 9 to drive the scraper 10 to move together with the shaft 7 inside the inlet pipe 1. The scraper 15, under the action of the fine-tuning spring 14, adheres tightly to the inner wall of the inlet pipe 1 and moves together with the scraper 10, thereby cleaning the inner wall of the inlet pipe 1 and preventing the reagent from crystallizing and adhering to the inner wall of the pipe, corroding the inner wall of the pipe or clogging the pipe. When the connecting rod 9 moves, it can stir the wastewater containing the reagent, thereby initially mixing it and shortening the subsequent reaction time. At the same time, the stirring and disturbance can prevent the reagent from depositing at the bottom of the pipe and reduce the probability of the reagent crystallizing inside the pipe. When the sewage is flowing, it can enter the scraper 10 through the water channel 11 and be sprayed onto the inner wall of the pipe through the nozzle 12 to assist the scraper 10 in cleaning the pipe and prevent crystals from adhering to the scraper 10 to form a "secondary pollution source". This avoids the accumulation of chemical crystals in the pipe and blockage when the sewage flow is low. As the sewage flow rate increases, the flow velocity of the sewage in the inlet pipe 1 increases accordingly. The speed at which the impeller 8 drives the shaft 7 to rotate increases, and the centrifugal force on the scraper 15 when it moves with the scraper 10 also increases. This results in greater pressure exerted by the scraper 15 on the inner wall of the pipe, and greater cleaning force. At the same time, the effect of greater sewage flow rate is achieved, with faster cleaning force and stirring speed. At low flow rates, gentle scraping reduces wear and extends the service life of the device. As the scraper 10 moves with the shaft 7, it periodically pushes the push rod 4 up and down through the ball head 5. This causes the push rod 4 to drive the valve column 302 to slide inside the bracket 301 through the push spring 6, lifting the valve plate 305 and releasing the valve plate 305 from the hopper 2. This allows the granular medicine contained in the hopper 2 to fall into the feed pipe, completing the medicine dispensing. As the sewage flow increases, the scraper 10 pushes the ball head 5 more frequently, which increases the frequency at which the valve column 302 drives the valve plate 305 to move, thus achieving the effect of automatically adjusting the dosage according to the sewage flow. Furthermore, when the valve column 302 moves the valve plate 305, it can vibrate the agent at the lower end of the hopper 2, and the vibration frequency is consistent with the drug dosing frequency, thereby preventing the agent from forming an arch structure at the discharge port due to moisture, and continuously destroying the bridging tendency between the agent particles to prevent the discharge port from being blocked. When the agent clumps at the discharge port of hopper 2, as the ball head 5 drives the push rod 4 to rise while the valve plate 305 cannot rise, the push spring 6 is compressed. The push rod 4 drives the plug 304 to move in the connecting cavity 303 through the toothed rod 310, pressing the oil in the connecting cavity 303 into the receiving groove 307 through the connecting groove 306. This pushes the crushing rod 308 out of the receiving groove 307. At the same time, the toothed rod 310 drives the valve 302 to rotate inside the bracket 301 through the double gear 309 and the toothed ring 311. This allows the valve plate 305 to drive the crushing rod 308 to rotate synchronously, crushing the clumped agent and preventing it from blocking the discharge port. After the slab is broken, the jacking spring 6 can drive the valve column 302 and valve plate 305 to move upward, while the toothed rod 310 and plug 304 also return to their original positions in the connecting cavity 303, causing the valve column 302 and valve plate 305 to rotate and perform secondary crushing on the remaining slab. At the same time, the oil will also draw the crushing rod 308 back into the receiving tank 307 to prevent the crushing rod 308 from being exposed to the agent for a long time and being corroded or adhered, thereby allowing the hopper 2 to resume normal dosing. When the shaft 7 rotates, it can drive the drive wheel 20 to rotate synchronously, which in turn drives the stirring rod 22 to rotate synchronously through the transmission wheel 21. This allows the stirring rod 22 to stir the agent in the hopper 2, preventing the agent from forming clumps in the hopper 2 under the action of moisture and pressure, which would prevent the agent from being properly added. After the sewage leaves the inlet pipe 1, the drive wheel 20 can block the sewage, allowing it to fall only into the right side of the partition 18 in the transfer box 16, preventing the sewage from flowing directly to the left side of the partition 18 and reducing the direct impact of the water flow on the sedimentation zone. After the wastewater enters the transfer tank 16, it will first be transferred on the right side of the partition 18. At the same time, the drive wheel 20 can agitate the upper part of the wastewater, so that the agent can be dispersed and integrated into the wastewater. When the wastewater level exceeds the upper end of the partition 18, it will overflow to the left side of the partition 18 and stand, thereby separating the large particles of dirt in it. The clear liquid on the upper layer can then flow out of the transfer tank 16 through the overflow port 17 to the subsequent treatment tank for further purification.
