Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and in particular to a sewage treatment agent dosing device. Background Art

[0002] In order to ensure that wastewater meets discharge standards or can be reused after treatment, a variety of chemical agents are required in the treatment process. According to different uses, these agents can be divided into the following categories:

[0003] (1) Flocculants: Sometimes also called coagulants, they can be used as a means to enhance solid-liquid separation and are used in primary sedimentation tanks, secondary sedimentation tanks, flotation tanks, and tertiary or advanced treatment processes;

[0004] (2) Coagulant aid: Assists flocculant to play its role and enhances the coagulation effect;

[0005] (3) Conditioning agent: also known as dehydrating agent, used to condition the residual sludge before dehydration. Its varieties include some of the above-mentioned flocculants and coagulant aids.

[0006] In the prior art, in order to reduce the harm to workers when the treatment agent is delivered, an automated treatment method is adopted. For example, the prior art with patent number CN118724118A adopts a floating device and uses a permanent magnet ring to connect the floating device to the drug device on the shore for drug delivery, and then the treatment is carried out. The driving means adopted includes a double-headed motor (502) and the like to drive the impeller to achieve the throwing effect of the hull.

[0007] However, this type of technology still causes the evaporation of liquid medicine particles in the air due to the small lift and spray particles during spraying. In particular, this type of delivery equipment cannot have an effect on the underwater part of the sewage, especially the adjustment of the dosage at different underwater depths. The mixing effect can only be achieved by relying on the sedimentation of the liquid medicine and the stirring and flow in the sewage pool. Ultimately, the medicine will float on the surface and evaporate, and a large amount of air pollution caused by the medicine will still occur within the scope of the sewage pool.

[0008] At the same time, the system structure can only complete automated drug administration and cannot form a time series record of scheduled sampling inside the sewage pool, resulting in the need to observe other real-time detection equipment again in the next drug administration process, especially when abnormal phenomena occur in sewage, it is impossible to form the ability to trace the sample.

[0033] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0034] In the first embodiment of the present invention, Figure 1-6As shown, a sewage treatment agent dosing device is provided, comprising a sewage pool 1, wherein the sewage pool 1 is provided with a agent storage component 2 and a agent dosing device 3;

[0035] The drug storage assembly 2 contains a drug delivery port and a stirring device. After drug delivery, the drug liquid is pumped out from the connecting pipe 201 according to the control of the water pump. The sampling pipe 202 is mainly used to extract sewage from deeper layers to the storage unit for storage. Since the drug storage assembly 2 is arranged in an array around the sewage pool 1, it can be collected in an intermittent time sequence or again after a certain period of time after the treatment agent has been added to the area.

[0036] The medicine delivery device 3 receives the medicine liquid mainly through the combination of the docking tube 404 and the connecting tube 201. The means of combination can be a permanent magnet ring or other telescopic rod-type buckling structure. After the combination is completed, the medicine liquid will enter the liquid chamber 307 according to the liquid pump 403. The liquid chamber 307, as the lowest structure, can be used as the ballast component of the entire medicine delivery device 3, that is, it sinks deeper when there is more liquid, and floats higher when there is less liquid. In this way, the relative position of the horizontal height of the connecting tube 201 and the docking tube 404, as well as the stability of the medicine delivery device 3 itself can be adjusted. For example, the medicine storage component 2 will float to the corresponding height consistent with the connecting tube 201 only after the medicine liquid in the liquid chamber 307 is drained. After the medicine liquid in the liquid chamber 307 is full, the medicine storage component 2 is less likely to overturn.

[0037] At the telescopic tube 303, the medicine liquid is mainly injected by the internal submersible pump 309, and then sprayed out from the nozzle 313 at the bottom of the telescopic tube 303. Since it is sprayed from the side and sprayed deeper, a corrugated air duct 304 is designed on the bottom side of the telescopic tube 303. When the telescopic tube 303 is extended, the corrugated air duct 304 will also extend by a corresponding length. The air pump 402 mainly applies pressure to the vertical fixed air duct in stages, and transmits it downward based on the one-way air valve, and enters the telescopic tube 303 from the corrugated air duct 304. The high pressure of the telescopic tube 303 will carry away air to the nozzle 313, and finally form bubbles underwater. The bubbles will drive the medicine liquid sprayed from the nozzle 313, allowing the medicine liquid to mix with the water surface of the sewage pool 1 at a deeper depth.

[0038] The telescopic tube 303 can adopt other different telescopic structures. Here, only the telescopic structure based on the screw rod is mentioned, such as Figure 3-5As shown, the mounting plate 314 blocks the liquid medicine from entering the upper space on the upper side of the cylinder 308; when it needs to be extended downward, the threaded shaft 312 rotates. Because the bottom of the telescopic tube 303 is limited by the bottom of the deep water tank 302 and can only move up and down, the threaded shaft 312 rotates and drives the screw nut 311 to move the telescopic tube 303 downward to a deeper depth. The liquid medicine mainly enters from the bottom of the cylinder 308 and then enters the interior through the liquid inlet 310 of the telescopic tube 303. After being mixed by the threaded shaft 312, it continues to move downward due to hydraulic pressure until it is sprayed out from the nozzle 313.

[0039] Since the bottom of the threaded shaft 312 itself is not fixed, long-term use will cause the rod to be eccentric. Therefore, the inner wall of the telescopic tube 303 is designed with an internal thread 315, and a hollow connecting frame 316 is sleeved on the bottom to allow the liquid medicine to move continuously downward. The external thread 317 on the surface of the connecting frame 316 can rotate correspondingly with the internal thread 315. While fixing the lower structure of the threaded shaft 312, it also allows the connecting frame 316 to assist in mixing the liquid medicine when it rotates internally.

[0040] A conventional drive assembly 501 is provided inside the cavity 306. The drive assembly 501 can be of any driving mode. In this embodiment, a double-headed motor 502, a transmission roller 503 and a gear set 504 are used to complete the control, thereby adjusting the drive blades 5 and staggering the cylinder 308 at the center. If necessary, the internal motor can also be used to drive the drive blade 5 structure, which is similar to the movement of a speedboat.

[0041] Specifically, the staff mainly controls themselves and the medicine delivery device 3 through the system host of the medicine storage component 2. The system host includes conventional hardware such as a CPU chip and a storage hard disk, and cooperates with a wireless transmission module, such as a WIFI module or a Zigbee module to complete the connection with the wireless receiving module of the medicine storage component 2. At the same time, the staff can also locate the specific position of the medicine delivery device 3 based on the connection between multiple medicine storage components 2 and a single medicine delivery device 3, that is, the positioning solution of the indoor WIFI module;

[0042] During control, the control scheme is mainly adjusted according to the internal needs of the sewage pool 1. For example, when the pH value in a certain area is abnormal, the extension length of the telescopic tube 303 and the gas spray intensity can be adjusted. At the same time, the main control unit 4 controls the hydraulic pressure of the submersible pump 309 to adjust the spray volume of the internal liquid.

[0043] When not normally started, the medicine delivery device 3 is powered by the solar panel 405 and the battery. If continuous operation is required, external power supply can be used for continuous charging.

[0044] In another embodiment of the present invention, a system for a sewage treatment agent dosing device is provided, wherein a sewage tank 1 comprises:

[0045] The drug storage assembly 2 includes a connecting tube 201, a sampling tube 202, a system host, a wireless connection and transmission module, and a sample storage unit. The drug storage assembly 2 is arranged in an array at the edge of the sewage pool 1 and is used to sample the sewage inside the sewage pool 1, send it to the main control terminal, and receive information sent by the main control terminal;

[0046] The agent delivery device 3 includes a floating raft 301 and a deep water tank 302. The deep water tank 302 includes a telescopic tube 303. The agent delivery device 3 is used to receive the treatment agent from the agent storage assembly 2 and receive control information through a wireless connection receiving module. According to the control information, the agent discharge amount and the agent discharge depth are adjusted based on the telescopic tube 303;

[0047] The main control end includes a cloud server, a sewage detector and an LTSM neural network algorithm. The main control end is used to detect sewage samples in real time, calculate the numerical trend of sewage in the target area according to the time sequence, and feed back the information to the reagent storage component 2.

[0048] The number of the medicine storage components 2 is no less than two, and the types of medicines stored in the medicine storage components 2 are different.

[0049] Specifically, the overall system is Figure 7 As shown, mainly in accordance with Figure 8 The control process of the system is completed. First, feedback is completed based on the sampling of the drug storage component 2. The sewage detector described above can also be integrated into the drug storage component 2 to form intelligent real-time detection and send it to the main control end for confirmation. Under normal use, the staff will take out the sewage samples collected at different time sequences from the drug storage component 2 according to abnormal conditions and put them into the sewage detector to obtain specific information, such as changes in microorganisms and pH values ​​in the sewage. The drug storage components 2 arrayed on the side of the sewage pool 1 are also divided into different management areas to deal with different information within the same sewage pool 1 area.

[0050] It is then output to the LTSM neural network algorithm. After constraining different change values, different data are collected in time series to test their correlation. The correlation strength between the data is judged according to the local dependence of the data set. Then the numerical change of the sewage pool in the subsequent time series can be obtained, and it is returned to the drug storage component 2 again. The nearest drug storage component 2 controls the drug delivery device 3 to the corresponding drug storage component 2 according to the real-time information. The drug delivery device 3 discharges the residual liquid inside during the movement and then refills other liquid. It enters the interval of the drug storage component 2 where the abnormality is detected to discharge the liquid. The drug delivery device 3 in this area then adjusts the amount of liquid to be discharged by the drug delivery device 3, the level of discharged liquid, and the range of discharged liquid.

[0051] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
