Description

Technical Field

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

[0002] Wastewater treatment is an environmental governance process that uses a combination of physical, chemical, and biological technologies to remove suspended solids, organic pollutants, nitrogen and phosphorus, heavy metals, pathogens, and other harmful impurities from domestic and industrial wastewater, so that the water quality meets national discharge standards or the requirements for reclaimed water reuse. Chemical dosing in wastewater treatment is a key auxiliary means that runs through the entire process. By adding specialized chemical agents, precise removal of pollutants, stable operation of the process system, and compliance of effluent quality are achieved. It is an indispensable operation in the physical and chemical treatment, biological enhancement, deep standardization, and sludge disposal stages.

[0003] After adding chemicals to wastewater treatment, stirring is a necessary step to ensure that the chemicals react fully with the wastewater. Traditional stirring and mixing devices mostly use rotating blades to stir in the wastewater tank to achieve the effect of mixing chemicals with wastewater. However, in this stirring method, the addition of chemicals and stirring are operated separately. Personnel need to add multiple chemicals separately. The chemicals are added from the top layer of wastewater, and the mixing equipment is used to achieve the effect of mixing with the wastewater. It is difficult for the chemicals to come into contact with the lower layer of wastewater, resulting in low chemical mixing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent chemical dosing and mixing device for wastewater treatment, so as to solve the problems of uneven mixing of chemicals and wastewater and low mixing efficiency mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dosing and mixing device for intelligent sewage treatment, comprising a support plate connected to a sewage tank, a drive roller rotatably mounted on the support plate, the drive roller being a hollow tube structure, and several connecting pipes fixedly connected to the outer side of the drive roller, with stirring rollers fixedly mounted at the outer ends of the several connecting pipes, and a discharge pipe fixedly connected to the bottom of the stirring rollers; an inner tube rotatably mounted inside the drive roller via bearings, and a pressurizing device mounted on the inner tube to pressurize the interior of the several stirring rollers; and a drive component mounted on the support plate to drive the drive roller and the inner tube to rotate.

A rod is slidably inserted into the bracket, and a fitting plate is fixed on the outside of the rod to abut against the bottom of the retaining ring. A fitting ring is fixed on the top of the rod to abut against the inner wall of the inner tube, and a compression spring is sleeved on the outside of the rod to abut against the bracket and the fitting plate.

[0008] Preferably, the top of the stirring roller is threaded with a sealing cap, and the outside of the stirring roller is fixed with a connecting hoop that is fixed to the discharge pipe.

[0009] Preferably, the discharge pipes connected to the outer sides of the several stirring rollers have different heights at their outer ends.

[0018] 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.

[0019] Example 1: Please refer to Figure 1 - Figure 5The diagram shows an intelligent wastewater treatment dosing and mixing device, including a support plate 1 connected to a wastewater tank. A drive roller 2 is rotatably mounted on the support plate 1. The drive roller 2 has a hollow tube structure. Several connecting pipes 3 are fixedly connected to the outside of the drive roller 2. A stirring roller 4 is fixedly mounted at the outer end of the connecting pipes 3. A discharge pipe 5 is fixedly connected to the bottom of the stirring roller 4. An inner tube 6 is rotatably mounted inside the drive roller 2 through a bearing. A pressurizing device 7 is installed on the inner tube 6 to pressurize the inside of the stirring rollers 4. A drive component 8 is mounted on the support plate 1 to drive the drive roller 2 and the inner tube 6 to rotate.

[0020] In this scheme, personnel use support plate 1 to install the equipment above the sewage tank or sewage bucket, and then use drive component 8 to provide power to drive the drive roller 2 to rotate. In order to facilitate the rotation of drive roller 2, a notch is opened at the bottom of drive roller 2. At the same time, a cam can be designed in the sewage tank or sewage bucket corresponding to the notch to facilitate the support of drive roller 2, so that several stirring rollers 4 can stir in the sewage to achieve a stirring effect. Meanwhile, the stirring roller 4 adds the medicine, and with the help of pressurization device 7, the medicine is injected into the middle layer of sewage during the stirring process, so that the medicine and sewage are mixed more evenly and the stirring efficiency of medicine mixing is improved.

[0021] It should also be noted that the pressurizing device 7 can also inject gas into the stirring roller 4 to achieve the effect of aerating and stirring the sewage, which can effectively help mix the agent and the sewage.

[0022] For further details, please refer to [link / reference]. Figure 3 - Figure 5 The drive roller 2 has two baffles 9 fixed inside. The inner tube 6 is rotatably connected to the two baffles 9. The inner tube 6 has a reciprocating thread groove engraved on the outer side between the two baffles 9. The pressurizing device 7 includes a piston plate 10 threadedly sleeved on the outer side of the inner tube 6. The inner wall of the drive roller 2 is fixed with a limit strip 11. The piston plate 10 slides and fits with the limit strip 11. A one-way valve for input to the stirring roller 4 is opened on the connecting pipe 3. An air intake regulating component 12 is installed on the inner tube 6. The intake adjustment component 12 includes a retaining ring 13 fixed on the inner wall of the inner tube 6. The inner tube 6 has a through hole 14 near the two baffles 9. A bracket 15 is fixed on the inner tube 6. A rod 16 is slidably inserted into the bracket 15. A fitting plate 17 that abuts against the bottom of the retaining ring 13 is fixed on the outside of the rod 16. A fitting ring 18 that abuts against the inner wall of the inner tube 6 is fixed on the top of the rod 16. A compression spring 19 that abuts against the bracket 15 and the fitting plate 17 is sleeved on the outside of the rod 16.

[0023] In this scheme, the principle of pressurizing the inside of the stirring roller 4 by the pressurizing device 7 is as follows: Power is provided by the drive component 8, which drives the inner tube 6 to rotate, so that the piston plate 10 moves back and forth along the reciprocating threaded groove on the outside of the inner tube 6. During the upward movement, the gas in the area above the piston plate 10 is compressed and input from the connecting pipe 3 to the stirring roller 4. The piston plate 10 begins to draw in gas under negative pressure. Under negative pressure, the bonding plate 17 is first drawn downward, causing the bonding plate 17 to detach from the retaining ring 13 and drive the bonding ring 18 to fit with the through hole 14 at the upper end of the inner tube 6. This allows the gas in the inner tube 6 to enter the area below the piston plate 10 through the through hole 14 at the lower end. At this time, the stirring roller 4 enters the gas through the connecting pipe 3 at the upper end, and the drug discharge or gas exhaust operation begins. When the piston plate 10 moves downward, the gas in the area below the piston plate 10 is compressed. At this time, the bonding plate 17 is tightly bonded to the retaining ring 13 under the action of the compression spring 19, while the bonding ring 18 is not bonded to the through hole 14 at the upper end of the inner tube 6. At this time, air begins to enter from the top of the piston plate 10, and the gas at the lower end of the piston plate 10 is input to the stirring roller 4 through the lower connecting pipe 3. When the gas enters the connecting pipe 3, the operation of discharging medicine or venting gas begins.

[0024] It should be noted that by moving the piston plate 10 up and down, the air intake regulating component 12 is driven to open and close the through holes 14 at the upper and lower ends of the inner tube 6, thereby realizing the separate intake of gas into the upper and lower ends of the piston plate 10 and realizing the continuous blowing operation of the stirring roller 4, thus realizing the operation of discharging medicine or exhausting gas.

[0025] In this design, to facilitate the addition of medicine inside the stirring roller 4, a sealing cap 20 is threaded onto the top of the stirring roller 4. At the same time, to ensure the stability of the discharge pipe 5 in the sewage, a connecting hoop that is fixed to the discharge pipe 5 is fixed on the outside of the stirring roller 4.

[0026] It should also be noted that, in order to improve the dispersion range of the drug in the wastewater, several discharge pipes 5 are designed to be connected to the outer sides of the stirring rollers 4, and the height of their outer ends is different.

[0027] For further details, please refer to [link / reference]. Figure 1 and Figure 2 The drive component 8 includes a drive motor 30 fixed on the support plate 1 via a motor frame. The output end of the drive motor 30 is fixed with a double shaft gear 31 via a coupling. A small gear 32 is fixed on the top of the inner tube 6. A large gear 33 is fixed on the top of the drive roller 2. The large gear 33 and the small gear 32 mesh with the double shaft gear 31. The operating principle of drive component 8 in this scheme is as follows: First, the equipment is installed and fixed by the support plate 1. Then, the drive motor 30 provides power to drive the dual-shaft gear 31 to rotate. During the rotation of the dual-shaft gear 31, it will mesh with the large gear 33 and the small gear 32 to drive them to rotate synchronously but at different speeds. Since the inner tube 6 and the drive roller 2 rotate at different speeds, the inner tube 6 rotates much faster than the drive roller 2. Therefore, the piston plate 10 on the outside of the inner tube 6 meets the lifting requirements.

[0028] Example 2: Please refer to Figure 6 and Figure 7 This embodiment further explains the first embodiment, the difference being that the internal structure of the stirring roller 4 is optimized. By adding the linkage 24 and the closing plate 22, the discharge pipe 5 can be closed when the drug is added, so as to prevent the drug from flowing out when it is added.

[0029] Specifically, a track plate 21 is fixed inside the stirring roller 4 at the connection point with the discharge pipe 5. A closing plate 22 is slidably installed inside the track plate 21. Two adjusting rods 23 are fixed on the closing plate 22. A linkage component 24 that is connected to the adjusting rods 23 is installed on the top of the stirring roller 4. The linkage component 24 includes a linkage plate 25 fixed to the top of the adjusting rod 23, which is connected to the stirring roller 4 through the sealing cover 20 to realize the compression of the linkage plate 25. The inner wall of the stirring roller 4 is fixed with a mounting plate 26 that is slidably inserted into the adjusting rod 23. The outer side of the adjusting rod 23 is fitted with a push-opening spring 27 that abuts against the mounting plate 26 and the linkage plate 25. In order to improve the lifting stability of the adjusting rod 23, a stabilizing sleeve 29 that is slidably fitted into the adjusting rod 23 is fixed on the inner wall of the stirring roller 4.

[0030] In this scheme, when personnel unscrew the sealing cap 20 to add medicine, the spring 27 is pushed open, causing the linkage plate 25 and the adjusting rod 23 to move upward, which in turn moves the closing plate 22 upward, closing the discharge pipe 5. This prevents the medicine from flowing out through the discharge pipe 5 when personnel add medicine. After the stirring roller 4 is filled, the sealing cap 20 is screwed on again. At this time, the sealing cap 20 will squeeze the linkage plate 25, causing the adjusting rod 23 and the closing plate 22 to move downward, so that the discharge pipe 5 is connected to the stirring roller 4 again. Under the action of the subsequent pressurizing device 7, the medicine is smoothly discharged out through the discharge pipe 5.

[0031] In order to ensure that the closing plate 22 can completely and smoothly block the discharge pipe 5, a limit end 28 is fixed on the outside of the adjusting rod 23.
