Description

Technical Field

[0001] This invention relates to the field of wastewater treatment dosing technology, specifically to an intelligent wastewater treatment dosing device and dosing method. Background Technology

[0002] Intelligent chemical dosing devices for wastewater treatment are advanced equipment that combines sensor technology, automated control, and artificial intelligence algorithms. They are used to optimize the dosage of chemical agents in the wastewater treatment process. The core objective is to improve treatment efficiency, reduce operating costs, and minimize environmental impact by precisely controlling the dosage of chemicals.

[0003] Wastewater treatment agents may exist in various physical states depending on their chemical properties, uses, and application scenarios. These mainly include solid (powder, granules, tablets, etc.), liquid (solution, emulsion), and gaseous states. Agents in different states have different characteristics in terms of storage, transportation, dosing methods, and reaction efficiency. In the wastewater treatment process, the pre-dissolution of chemicals before dosing is a key step to ensure that the chemicals can play their full role. If the chemicals (such as flocculants, coagulants, pH adjusters, etc.) are not fully dissolved or dispersed, it may lead to uneven dosing, waste of chemicals, or even equipment blockage. The entire pre-dissolution process requires a dedicated dissolution tank or dissolution vessel, supplemented by a dosing system, thermometers, pH meters, concentration detectors, etc., and involves a series of steps including first preparing the medicine, then dissolving, then maturing, and finally filtering. However, the steps of preparing the medicine and dissolving and mixing cannot be flexibly connected, which affects the efficiency of dosing in wastewater treatment. To address this, we propose an intelligent dosing device and dosing method for wastewater treatment. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent dosing device and dosing method for wastewater treatment, so as 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 intelligent dosing device, including a dosing platform, a rotating drum movably connected to the dosing platform, a drug storage and mixing mechanism uniformly and symmetrically installed on the side wall of the rotating drum, and a drug storage mechanism fixedly connected to the top of the dosing platform; The drug storage and mixing mechanism includes a mixing tank, a rotating shaft, a lifting arm, and a sliding sleeve. The mixing tank is uniformly fixed to the side wall of the rotating cylinder. The rotating shaft is movably connected inside the mixing tank. The lifting arm is symmetrically rotatably connected to the side wall of the rotating shaft. A sliding sleeve is slidably connected to the rotating shaft and located at the top of the lifting arm. A sealing sleeve is fixedly connected to the top of the sliding sleeve and located on the inner wall of the mixing tank. A stirring ball is welded and fixed to the end of the lifting arm. The drug storage mechanism includes a box, a main pipe and a branch pipe. The side wall of the box is connected to the main pipe and the branch pipe. The side wall of the mixing tank is connected to and fixed with a drug addition channel. The main pipe on the side of the box is correspondingly set with the drug addition channel.

[0006] Furthermore, the drug storage and mixing mechanism also includes a sealing arc plate frame, which is sleeved on the side wall of the sliding sleeve and slidably connected to the inner wall of the mixing tank. The side wall of the mixing tank has an opening that communicates with the inner wall of the rotating drum.

[0007] Furthermore, a rotating head is installed on the top of the mixing tank, the bottom of the rotating head penetrates the mixing tank and is connected to the rotating shaft, a limit ring is fixedly connected to the inner wall of the mixing tank and located on the side of the stirring ball, and a sealing rotating plate is rotatably connected to the bottom of the side wall of the mixing tank.

[0008] Furthermore, a limiting sleeve is fixedly fitted on the top of the dosing platform and on the outer wall of the rotating cylinder, and the protrusion on the side of the sealing rotating plate abuts against the bottom of the limiting sleeve.

[0009] Furthermore, the medicine storage mechanism also includes a first chamber, a second chamber, and a third chamber. The box body has a first chamber, a second chamber, and a third chamber. The first chamber and the second chamber are respectively connected to the side branch pipes, and the third chamber is connected to the main pipe. A control valve is installed on the branch pipe.

[0010] Furthermore, a limiting rail is fixedly connected to the top of the mixing tank on the dosing platform, and a turntable is movably connected to the limiting rail on the dosing platform. A drive motor is fixedly connected to the top of the dosing platform, and the output end of the drive motor is connected to the turntable. The bottom groove of the turntable is correspondingly set with the top protrusion of the rotating head. A leak-proof cover is fixedly connected to the side wall of the dosing platform, and a liquid storage tank is installed on one side of the dosing platform.

[0011] The dosing method of this intelligent dosing device for wastewater treatment is as follows: Selective water mixing and dosing, with the top of the leak-proof cover as the dosing area, and two mixing tanks on opposite sides of the rotating drum as a group for adding sewage treatment agents. When the valve on one side of the branch pipe on the box is opened, the granular agent automatically enters the mixing tank along the main pipe. As the drum rotates, the mixing tank carrying the wastewater treatment agent rotates to the turntable area. The protrusion on its top rotating head contacts the inner turntable groove of the limiting track. At the same time, the drive motor drives the turntable to rotate, realizing the rotation of the shaft inside the mixing tank. The centrifugal force generated by the rotation causes the stirring ball on the lifting arm to be suspended in the air and contact the limiting retaining ring. Simultaneously, the lifting arm rotates, pulling the sliding sleeve downwards, causing the sealing sleeve to disengage from the discharge port and the agent to fall automatically. At the same time, the downward movement of the sliding sleeve causes the sealing arc frame to move synchronously, causing the water inside the rotating drum to flow into the mixing tank along the opening. Along with the mixing of the agent and the liquid, and with the stirring ball, the sewage treatment agent is dissolved. Then, as the rotating drum rotates, the sealing plate contacts the notch on the limit ring, causing the sealing plate to open, and the agent mixture automatically flows into the leak-proof cover, realizing automatic drug dispensing.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, fully automatic precision dosing is adopted. Through the fixed-angle rotation of the drum and the multi-chamber design of the dosing mechanism, the automatic proportioning and quantitative dosing of various agents are realized, which significantly improves the dosing accuracy and efficiency. The dosing mechanism supports multi-agent partitioned storage, and the branch pipe control valve can flexibly switch the types of agents to meet the needs of different sewage treatment scenarios. 2. In this invention, a highly efficient mixing and dissolving process is employed. The lifting arm and stirring ball, driven by a rotating shaft, expand under centrifugal force, and the stirring range is controlled by a limiting ring to ensure that the agent and solvent are fully mixed and to avoid residue. At the same time, the rotation of the lifting arm can also control the position of the entire sliding sleeve. As the rotation speed of the rotating shaft increases, the movement of the sliding sleeve enables the agent at the top of the mixing tank to fall and the inlet to open automatically. The proportioned solvent and agent are automatically mixed and dissolved under the stirring of the lifting arm, while the dosing tank on the other side begins a new round of automatic dosing. The operation steps are compact, significantly improving the accuracy and efficiency of dosing. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-7 The present invention provides a technical solution: Example 1: Solid reagents are low-cost and suitable for centralized storage and automated dissolution and dosing. Common examples include PAC, aluminum sulfate, and lime. Figure 1 As shown, the intelligent dosing device for wastewater treatment is mainly used for dissolving and dispensing solid wastewater treatment agents. The main dosing station 1 is equipped with a drug storage mechanism 9 on its top, which is used for storing solid drugs and automatic dosing, such as... Figure 6 As shown, the box 901 is divided into three cavities, which correspond to cavities 1 (902), 2 (903), and 3 (904) from left to right. Based on the approximate dosage ratio of wastewater treatment agents, the agent with the largest dosage is stored in cavities 1 (902) to avoid frequent replenishment. A main pipe 905 and a branch pipe 906 are fixedly connected to the side wall of the housing 901. The first chamber 902 and the second chamber 903 are connected to the branch pipe 906 respectively. The third chamber 904 is connected to the main pipe 905. The branch pipe 906 is also connected to the main pipe 905. The drug is automatically discharged to the corresponding dosing channel 4 through the main pipe 905. A control valve is installed on the branch pipe 906. Usually, chamber 3 904 is used for liquid storage of the cleaning dosing device, while chamber 1 902 and chamber 2 903 are mainly used for chemical storage. If there are many types of chemicals to be added, the box 901 with more chambers is used instead. The flow of chemicals is controlled by the control valve. A rotating drum 2 is movably connected to the top of the dosing platform 1. The rotating drum 2 with a toothed sleeve is rotated at a fixed angle by a motor on the inner wall of the dosing platform 1. Considering that there are four drug storage and mixing mechanisms 3 installed on the side of the rotating drum 2, the mixing ratio is based on the chamber of the drug storage mechanism 9. That is, two mixing tanks 301 on opposite sides are used as a group for storing a single solid drug, and another group is used for storing another type of drug. By rotating the drum 2 at a fixed angle, the mixing tank 301 is moved to the bottom side of the main pipe 905, as follows. Figure 1 As shown, a dosing channel 4 is fixedly connected to the side wall of each mixing tank 301 for this purpose, as follows: Figure 5 As shown, the dosing channel 4 is connected to the mixing tank 301. The total amount of the agent added at one time continuously flows into the single mixing tank 301 along the dosing channel 4 for temporary storage. The reason for "temporary" is as follows Figure 5As shown, the mixing tank 301 is divided into upper and lower parts, which are connected and separated by a sealing sleeve 304 fitted on the rotating shaft 302. The medicine discharged into the dosing channel 4 flows to the upper part of the mixing tank 301 for storage. Only when the sealing sleeve 304 moves will the medicine flow to the lower part of the mixing tank 301. A rotating sealing plate 7 is installed on the bottom outlet side of the mixing tank 301. The mixing tank 301 rotates in conjunction with the rotating drum 2. A limiting collar 6 is fixedly fitted on the top of the dosing platform 1 and on the outer wall of the rotating drum 2. The entire limiting collar 6 is as follows: Figure 3 As shown, the sealing rotating plate 7 installed at the bottom of the side wall of the mixing tank 301 abuts against the bottom of the limiting sleeve 6 on one side, thereby achieving the pressing of the top rubber ring of the sealing rotating plate 7 against the outlet side of the mixing tank 301 to complete the sealing work. As the rotating drum 2 rotates, the bottom sealing plate 7 of the synchronously rotating mixing tank 301 begins to contact the "V"-shaped notch side of the limiting ring 14, causing the agent to squeeze the sealing plate 7 to rotate and automatically complete the drainage work. Since there is a delay in the complete opening of the sealing plate 7, to prevent the mixed agent from being accurately placed, a leak-proof cover 15 is installed on the top of the entire dosing platform 1 to carry out the drainage and collection work.

[0017] Example 2: To automate the dissolution of the added drug, the entire drug storage and mixing mechanism 3 is as follows: Figure 5 As shown, a rotating shaft 302 is movably connected inside the mixing tank 301. The end of the rotating shaft 302 passes through the mixing tank 301 and is connected and fixed to a rotating head 5. The top of the rotating head 5 is provided with two columnar protrusions. Oppositely, a limit track 11 is provided at the bottom of the entire dosing platform 1. Figure 4 As shown, a turntable 12 is also movably connected inside the limiting track 11. The turntable 12 is correspondingly set with the drive motor 10 installed on the top of the dosing station 1, and its rotation is controlled by the drive motor 10. Due to the installation of the limiting rail 11, the top protrusion of the rotary head 5 rotates along the limiting rail 11, keeping the top protrusion of the rotary head 5 in a stable moving state. The side of the dosing platform 1 corresponding to the drive motor 10 is the drug mixing area. When the rotating drum 2 drives the mixing tank 301 to the bottom of the drive motor 10, the protrusion of the rotary head 5 at the top of the mixing tank 301 engages with the groove of the turntable 12 in the limiting rail 11. At this time, the line connecting the centers of the two protrusions on the rotary head 5 coincides with the groove on the turntable 12. As the turntable 12 rotates, the groove begins to contact the top protrusion of the rotary head 5, thereby driving the rotating shaft 302 connected to the entire rotary head 5 to rotate. like Figure 5As shown, a lifting arm 305 is symmetrically connected to a rotating shaft 302 inside a mixing tank 301. A stirring ball 306 is fixedly connected to the end of the lifting arm 305. As the rotation speed of the rotating shaft 302 increases, the centrifugal force on the stirring ball 306 drives the entire lifting arm 305 to unfold. Due to the restriction of the mixing tank 301, the stirring ball 306 is prevented from frequently contacting the inner wall of the mixing tank 301, which could cause damage to the mixing tank 301 due to friction. A limiting ring 14 is fixedly connected to the inner wall of the mixing tank 301. Unlike ordinary regular inner wall rings, this application fills the inner wall of the limiting ring 14 with a convex anti-wear material to limit the rotation angle of the lifting arm 305 in a specific area. A sliding sleeve 303 is rotatably connected to the top of the lifting arm 305 via a connecting rod. A sealing sleeve 304 is fixedly fitted on the outer wall of the sliding sleeve 303. As the rotating shaft 302 rotates, the unfolded lifting arm 305 pulls down the entire sliding sleeve 303, causing the solid medicine at the top of the mixing tank 301 to fall down along the outer wall of the sliding sleeve 303 to the bottom of the tank. At the same time, it prevents the medicine from clogging the opposite side of the mixing tank 301 and the sliding sleeve 303. The convex surface of the inner wall of the limiting ring 14 is set to limit the angle of movement of the lifting arm 305 during rotation, so that the sliding sleeve 303 is not in a stationary state, but shakes up and down continuously, allowing the blocked medicine to fall down quickly. As the lifting arm 305 rotates continuously, the reagent at the top of the tank reaches the bottom, and at the same time, the solution needs to be drained, such as... Figure 5 As shown and Figure 7 As shown, an opening 13 is provided on the inner wall of the mixing tank 301. The opening 13 is connected to the rotating drum 2. The solvent is stored in the middle of the rotating drum 2 to prevent the solvent from flowing into the two sets of mixing tanks 301 indiscriminately. For this purpose, a sealing arc plate frame 307 is fitted on the entire sliding sleeve 303. It is supported by the entire sliding sleeve 303, but does not rotate synchronously with the rotating shaft 302. As the height of the sliding sleeve 303 decreases, the entire sealing arc plate frame 307 moves downward synchronously. One side of the sealing arc plate frame 307 abuts against the opening 13, sealing the entire opening 13. When the sealing arc plate frame 307 moves downward, the opening 13 is exposed, and the solvent continuously flows into the mixing tank 301 along the opening 13 to mix with the agent. To replenish the solvent, a liquid storage tank 8 is installed on the back side of the dosing platform 1, which is connected to the top of the entire rotating drum 2 through a conduit, and continuously delivers solvent into the rotating drum 2. As the stirring ball 306 and the lifting arm 305 rotate, the reagent is stirred and mixed, accelerating the dissolution of the reagent, such as... Figure 1 As shown, when the leftmost side starts to add and mix the agent, the rightmost mixing tank 301 in the same group starts to replenish the agent. When the agent mixing is finished, as the rotating drum 2 rotates, the bottom sealing plate 7 of the mixing tank 301 starts to contact the notch of the limiting sleeve 6, the sealing plate 7 opens automatically, and the mixed sewage treatment agent is automatically discharged into the leak-proof cover 15. By setting up an automatic mixing and dissolving mechanism, the rotating shaft 302 drives the mixing tank 301 to move to a special area, realizing the automatic addition of medicine and solvent. Combined with the quantitative addition of medicine by the medicine storage mechanism 9, the lifting arm 305 rotates synchronously to complete the high-speed dissolution of medicine in the mixing tank 301. Compared with first weighing the medicine and then adding it, followed by stirring and mixing, there is a pause operation that affects the overall dosing efficiency. Through the synergistic effect of rotary drum 2, centrifugal stirring, dynamic sealing control and multi-chamber dosing system, the automated proportioning, efficient mixing and precise dosing of wastewater treatment agents are realized. Compared with traditional devices, its intelligent mechanical linkage design significantly improves treatment efficiency, mixing uniformity and environmental adaptability.

[0018] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications and substitutions to the specific embodiments described, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, and all such modifications and substitutions should fall within the protection scope of the present invention.
