Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, and more specifically, to a sewage treatment agent precise delivery monitoring device. Background Art

[0002] With the rapid development of industrialization and urbanization, the amount of sewage discharge is increasing. Sewage treatment has become a key link in environmental protection. During the sewage treatment process, various chemicals need to be added, such as flocculants (polyaluminum chloride), disinfectants (sodium hypochlorite, etc.), acid-base regulators (sulfuric acid, sodium hydroxide, etc.), etc., to achieve the purposes of removing pollutants in sewage, regulating water quality and disinfection. Traditional chemical addition methods often rely on manual experience and judgment. Operators determine the amount of chemical to be added based on the general appearance of the sewage (such as turbidity) or fixed time intervals. This method lacks precision and can easily lead to insufficient or excessive chemical addition.

[0003] In response to the above problems, regarding the technical problem that the traditional method of drug administration often relies on manual experience and judgment, which lacks accuracy and easily leads to insufficient or excessive drug administration, after a lot of searches, a sewage treatment device with patent publication number CN215480211U was found, which can monitor the PAC dosage in real time. It belongs to the technical field of sewage treatment equipment. The device can respectively detect the water quality inside the water inlet pipe and two sets of outlet pipes by installing three sets of water quality detectors, and then the test results can be fed back to the sampling and analysis structure electrically connected to it. After the sampling and analysis structure analyzes the orthophosphate concentration in the water quality at the water inlet pipe and the two sets of outlet pipes, the sampling and analysis structure relies on the built-in artificial intelligence algorithm and combines similar historical data curves to calculate the current optimal PAC dosage in real time. The signal is transmitted to the BLDC dosing pump via the communication line to control the dosage, thereby realizing accurate dosing of sewage.

[0004] However, the aforementioned sewage treatment equipment capable of real-time monitoring of PAC dosage still has some issues. For example, the device can only administer liquid chemicals, but encounters certain inconveniences when administering solid chemicals. To address these issues, the present invention proposes a precise monitoring device for the administration of sewage treatment chemicals. Utility Model Content

[0023] The following is a combination of the appended examples of the present invention Figure 1-Figure 4 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0024] See also Figure 1-4 In the embodiment of the present invention, a precise feeding monitoring device for sewage treatment reagents includes a treatment box 1 and a liquid inlet 6 and a liquid discharge port 7 connected to both sides of the treatment box 1, a feeding box 2, which is fixedly connected to the treatment box 1, a feeding hopper 4 is connected to the feeding box 2, and an electric valve 22 for controlling its opening and closing is provided on the feeding box 2. A control mechanism 5 connected to the electric valve 22 is provided on the feeding box 2, a fixing frame 15, which is fixedly connected to the inside of the feeding box 2, and a first fixing plate 14 is rotatably connected to the fixing frame 15. End, a gravity sensor 20 connected to the signal of the control mechanism 5 is fixedly connected to the fixed plate 14, and a collecting hopper 21 arranged opposite the feed hopper 4 is fixedly connected to the gravity sensor 20. A connecting port 25 arranged opposite the discharge end of the collecting hopper 21 is penetrated by the feeding box 2 and the processing box 1. The electric telescopic rod 13 is fixedly connected in the feeding box 2 and is connected to the signal of the control mechanism 5. The telescopic end of the electric telescopic rod 13 is hinged with a connecting rod 24, and the end of the connecting rod 24 facing away from the electric telescopic rod 13 is hinged to the second end of the fixed plate 14.

[0025] Specifically, sewage enters the treatment box 1 through the liquid inlet 6 and waits for treatment. The medicine is added to the feeding box 2 through the feed hopper 4. The electric valve 22 on the feed hopper 4 is controlled by the control mechanism 5 and can be opened or closed as needed to control the entry of the medicine. When the medicine falls from the feed hopper 4, the collecting hopper 21 set therefor receives the medicine. The collecting hopper 21 is fixed on the fixed plate 14 through the gravity sensor 20. The gravity sensor 20 is connected to the control mechanism 5 signal, and can monitor the weight of the medicine in the collecting hopper 21 in real time and transmit the weight information to the control mechanism 5. When there is a certain weight of medicine in the collecting hopper 21, the gravity sensor 20 is sensed and sends a signal to the control mechanism 5, so that the control mechanism 5 controls the electric valve 22 to open or close the valve. The movable valve 22 is closed, and then the electric telescopic rod 13 is controlled to extend and retract. The telescopic end of the electric telescopic rod 13 drives the fixed plate 14 to rotate around the fixed frame 15 through the connecting rod 24. The rotation of the fixed plate 14 causes the collecting bucket 21 to tilt. The medicine in the collecting bucket 21 enters the treatment box 1 through the connecting port 25, is mixed with the sewage for treatment, and the treated sewage is discharged from the drain port 7. After the medicine in the collecting bucket 21 is discharged, the control mechanism 5 drives the electric telescopic rod 13 to reset, and then the electric valve 22 is reopened, and the medicine is discharged into the collecting bucket 21 again to facilitate the next medicine delivery. The overall operation is simple, and it is easy to realize the monitoring of the delivery of solid medicines. The weight of each delivered medicine can be accurately controlled to improve the sewage treatment effect.

[0026] It should be noted that the control mechanism 5 determines whether it is necessary to add chemicals and the amount of chemicals to be added based on pre-set parameters and real-time monitoring data (such as sewage water quality indicators, liquid level in the treatment box 1, etc.). If chemicals need to be added, the control mechanism 5 controls the electric valve 22 to open, allowing the chemicals to fall into the collection bucket 21. At the same time, the gravity sensor 20 feeds back the weight information of the chemicals in the collection bucket 21 to the control mechanism 5 in real time. When the weight of the chemicals in the collection bucket 21 reaches the required amount of chemicals to be added, the control mechanism 5 controls the electric valve 22 to close and stop adding chemicals. Then, the control mechanism 5 controls the electric telescopic rod 13 to move, so that the collection bucket 21 tilts and pours the chemicals into the treatment box 1. The entire chemical addition process is automatically controlled by the control mechanism 5, which reduces manual intervention, reduces labor intensity, and improves work efficiency. Automated operation can also reduce human errors, improve the accuracy and stability of chemical addition, and ensure the quality of the sewage treatment process. Furthermore, the control mechanism 5 of the equipment can adopt advanced microprocessors or microprocessors. The programmed logic controller (PLC) has powerful computing and control capabilities, can quickly and accurately process various signals and data, and achieve precise control of the dosage of the medicine. At the same time, in order to improve the reliability and stability of the equipment, redundant designs or spare parts can be set on key components (such as the electric valve 22, the electric telescopic rod 13, the gravity sensor 20, etc.) so that they can be switched in time when a fault occurs to ensure the normal operation of the equipment; in actual applications, the parameters of the equipment can be adjusted and optimized according to different sewage treatment requirements and medicine characteristics. For example, the capacity of the collection bucket 21, the opening speed of the electric valve 22, the extension speed of the electric telescopic rod 13, etc. can be adjusted to meet different medicine dosage requirements; secondly, in order to ensure the safe operation of the equipment, various safety protection devices can be set on the equipment, such as overload protection, limit protection, etc. At the same time, the equipment should be regularly maintained and serviced, the working status of each component should be checked, and damaged components should be replaced in time to ensure the long-term stable operation of the equipment.

[0027] In the embodiment of the present utility model, Figure 4As shown, a cylindrical and hollow fixed cylinder 26 is fixedly connected in the feeding box 2, and a rotating shaft 16 is rotatably connected in the fixed cylinder 26. The rotating shaft 16 extends to the outer wall of the feeding box 2, and a support plate 10 is fixedly connected to the feeding box 2. A motor 8 connected to the signal of the control mechanism 5 is fixedly connected to the support plate 10. The driving end of the motor 8 is fixedly connected to the rotating shaft 16, and a plurality of partitions 17 that slide in contact with the inner wall of the fixed cylinder 26 are fixedly connected along the direction of the rotating shaft 16. The top of the fixed cylinder 26 is connected to the discharge end of the collecting hopper 21 and is connected to the collecting hopper 18. The bottom of the fixed cylinder 26 is connected to the connecting hopper 19, and the connecting hopper 19 is connected to the connecting port 25. Specifically, when the medicine in the collecting hopper 21 needs to be further precisely controlled for delivery or temporary storage, the medicine falls into the fixed cylinder 26 from the discharge end of the collecting hopper 21. The collecting hopper 18 at the top and the motor 8 are operated under the signal control of the control mechanism 5. The driving end of the motor 8 drives the rotating shaft 16 to rotate. The rotating shaft 16 is located in a fixed cylinder 26 with a cylindrical and hollow structure. The multiple partitions 17 fixedly connected along the direction of the rotating shaft 16 rotate with the rotating shaft 16. When the collecting hopper 18 is facing a certain storage cavity, the medicine falls into the storage cavity for temporary storage. When the medicine needs to be added, the motor 8 rotates the rotating shaft 16 according to the instruction of the control mechanism 5, so that the storage cavity containing the medicine rotates to the position of the connecting bucket 19 connected to the bottom of the fixed cylinder 26. The medicine enters the treatment box 1 through the connecting bucket 19 and the connecting port 25 and is mixed with sewage for treatment. The setting of the overall structure increases the temporary storage and quantitative addition functions of the medicine, and at the same time provides a stable storage environment for the medicine.

[0028] It should be noted that in order to ensure the tight fit between the partition 17 and the inner wall of the fixed cylinder 26, sealing materials such as rubber strips can be used on the edge of the partition 17 to prevent the medicine from leaking into other storage cavities or the outside of the fixed cylinder 26 during rotation. The selection of the motor 8 should take into account its parameters such as speed, torque and accuracy to meet the requirements of different medicine delivery speed and accuracy. At the same time, a speed regulation device can be equipped to adjust the speed of the motor 8 according to actual conditions; in the design of the fixed cylinder 26, it can be considered to add an observation window or sensor for real-time monitoring of the storage status of the medicine in the storage cavity, so that the control mechanism 5 can timely grasp the remaining amount and delivery status of the medicine.

[0029] In the embodiment of the present utility model, Figure 4As shown, a storage cavity is formed between adjacent partitions 17, and the maximum length of the distance between adjacent partitions 17 is greater than the diameter of the discharge end of the collecting hopper 18. Specifically, this has the advantage of ensuring that the medicine can fall smoothly into the storage cavity, while avoiding mutual interference between medicines in multiple storage cavities; further, the collecting hopper 21 is a ash hopper type structure, and the discharge end of the collecting hopper 21 is set away from the connecting rod 24, so that when the fixed plate 14 rotates, the collecting hopper 21 can pour the medicine into the connecting port 25 more smoothly, while avoiding interference of the connecting rod 24 on the discharge process, making the medicine delivery more stable and reliable.

[0030] In the embodiment of the present utility model, Figure 2 、 Figure 3 and Figure 4 As shown, the treatment box 1 is fixedly connected to a filter screen 23 with an L-shaped structure at the position of the liquid inlet 6, and a cleaning port 9 is opened on the top of the treatment box 1 facing the filter screen 23. The cleaning port 9 is detachably connected to a cover plate 12. Specifically, when sewage enters the treatment box 1, the filter screen 23 first filters the larger impurities in the sewage to prevent these impurities from damaging subsequent treatment processes and equipment; when the filter screen 23 accumulates a lot of impurities and needs to be cleaned, the cover plate 12 can be removed and the filter screen 23 can be cleaned through the cleaning port 9 to ensure the filtering effect of the filter screen 23.

[0031] In the embodiment of the present utility model, Figure 1 and Figure 4 As shown, a liquid level sensor 11 connected to the control mechanism 5 signal is fixedly connected to the treatment box 1, and the detection head of the liquid level sensor 11 extends into the interior of the treatment box 1. Specifically, the liquid level sensor 11 monitors the liquid level height of the sewage in the treatment box 1 in real time, which helps the control mechanism 5 to adjust various parameters in the sewage treatment process according to the liquid level height, such as the amount of chemical dosage, etc. At the same time, it is convenient for the operator to understand the liquid level situation in the treatment box 1 and ensure the safe and stable operation of the equipment.

[0032] In the embodiment of the present utility model, Figure 3 As shown, an inspection door 3 is detachably connected to the feeding box 2. Specifically, when the equipment fails or needs maintenance, the inspection door 3 can be opened to inspect and repair the components inside the feeding box 2.

[0033] Working principle: Sewage enters the treatment box 1 through the liquid inlet 6 and waits for treatment. The medicine is added to the feeding box 2 through the feed hopper 4. The electric valve 22 on the feed hopper 4 is controlled by the control mechanism 5 and can be opened or closed as needed to control the entry of the medicine. When the medicine falls from the feed hopper 4, the collection hopper 21 set opposite it receives the medicine. The collection hopper 21 is fixed on the fixed plate 14 through the gravity sensor 20. The gravity sensor 20 is connected to the control mechanism 5 signal and can monitor the weight of the medicine in the collection hopper 21 in real time. The weight information is transmitted to the control mechanism 5. When a certain weight of medicine is stored in the collection hopper 21, the gravity sensor 20 senses it and sends a signal to the control mechanism 5, so that the control mechanism 5 controls the electric valve 22 to close, and then controls the electric telescopic rod 13 to extend and retract. The telescopic end of the electric telescopic rod 13 drives the fixed plate 14 to rotate around the fixed frame 15 through the connecting rod 24. The rotation of the fixed plate 14 causes the collection hopper 21 to tilt, and the medicine falls from the discharge end of the collection hopper 21 into the collection hopper 18 on the top of the fixed cylinder 26. The motor 8 operates under the signal control of the control mechanism 5. The driving end of the motor 8 drives the rotating shaft 16 to rotate. The rotating shaft 16 is located in the fixed cylinder 26 with a cylindrical and hollow structure. The multiple partitions 17 fixedly connected along the direction of the rotating shaft 16 rotate together with the rotating shaft 16. When the collecting hopper 18 is facing a certain storage cavity, the medicine falls into the storage cavity for temporary storage. When the medicine needs to be added, the motor 8 rotates the rotating shaft 16 according to the command of the control mechanism 5, so that the storage cavity filled with the medicine rotates to the connecting hole at the bottom of the fixed cylinder 26. At the position of the through bucket 19, the medicine enters the treatment box 1 through the connecting bucket 19 and the connecting port 25 and is mixed with the sewage for treatment. The treated sewage is discharged from the drain port 7. After the medicine in the collecting bucket 21 is discharged, the control mechanism 5 drives the electric telescopic rod 13 to reset, and then the electric valve 22 is reopened, and the medicine is discharged into the collecting bucket 21 again to facilitate the next medicine delivery. The overall operation is simple, which is convenient for monitoring the delivery of the medicine and can accurately control the weight of each delivered medicine to improve the sewage treatment effect.
