Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, and in particular to a pH adjusting tank with anti-corrosion function. Background Technology

[0002] In numerous industrial sectors, including chemical, environmental protection, food, and pharmaceutical industries, precise pH control is crucial for ensuring smooth production processes and stable product quality. In chemical production, the rate of many chemical reactions, the purity of products, and their yields are highly dependent on the pH of the reaction system. In environmental protection, the treatment of industrial wastewater and domestic sewage requires adjusting the pH to an appropriate range to meet the requirements of subsequent treatment processes and improve pollutant removal efficiency. In the food and pharmaceutical industries, precise pH control directly impacts product safety and efficacy.

[0003] A search revealed Chinese Patent Publication No. CN214780966U, which discloses a pH adjusting tank with anti-corrosion function for treating desulfurization wastewater in thermal power plants. The tank includes a tank body and a rotating roller. A partition is fixed inside the tank body. A first connecting groove is formed on one side of the tank body, and a second connecting groove is formed on the side of the heater near the connecting rod. A sliding groove is formed on one side of the heater, and a limiting groove is formed inside the sliding groove. A push rod is connected to the side of the sliding groove near the concave groove, and fixing blocks are fixed on both sides of the push rod. A spring connects the fixing blocks and the limiting groove. The rotating roller is connected to one side of the tank body. This pH adjusting tank with anti-corrosion function for treating desulfurization wastewater in thermal power plants is equipped with a partition. After the operator injects acid or alkali solutions into the tank body, during the acid-base neutralization reaction inside the device, the partition containing epoxy resin can isolate the acid or alkali solutions inside the tank body from the tank body, preventing corrosion and damage to the tank body.

[0004] The aforementioned patent specification mentions that "the partition isolates acidic and alkaline liquids, preventing corrosion and damage to the interior of the tank." While the patent isolates the tank, it is inconvenient to adjust the pH value of different liquids. Therefore, a pH adjusting tank with anti-corrosion function is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pH adjusting tank with anti-corrosion function, aiming to improve the problem that the existing technology cannot change and adjust according to the value of the liquid in the pipe.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pH adjusting tank with corrosion resistance includes a tank body, an adjusting mechanism fixedly connected to the top of the tank body, a cleaning mechanism fixedly connected to the top of the tank body, a discharge port fixedly connected to the inner wall of the tank body, and a coordinating mechanism installed on the inner wall of the cleaning mechanism.

[0008] The adjusting mechanism includes a fixing block, the bottom of which is fixedly connected to the top of the tank body. A pneumatic cylinder is fixedly connected to the inner wall of two of the fixing blocks. A piston is fixedly connected to the driving end of the pneumatic cylinder. A connecting pipe one is slidably connected to the outside of the piston. A connecting pipe two is fixedly connected to the other end of the connecting pipe one. Two material conveying components are fixedly connected to the inner wall of the connecting pipe two.

[0009] Through the above technical solution, the regulating mechanism constructs a precise and efficient liquid pH regulating system. The fixed block firmly supports the core components such as the pneumatic cylinder, ensuring stable operation of the mechanism. The pneumatic cylinder drives the piston to slide back and forth in the first connecting pipe, and transmits the power to the material transfer component through the second connecting pipe, realizing the quantitative extraction and delivery of reagents in the storage tank. This mechanical linkage design can not only respond quickly to changes in liquid concentration, but also significantly improve the accuracy and efficiency of pH value regulation by precisely controlling the reagent flow rate, effectively avoiding human operation errors and meeting the liquid regulation needs under different working conditions.

[0010] As a further description of the above technical solution:

[0011] The cleaning mechanism includes a motor, the bottom of which is fixedly connected to the top of the tank. A rotating rod is fixedly connected to the drive end of the motor. Multiple connecting plates are fixedly connected to the outside of the rotating rod. A fixed plate is fixedly connected to the drive end of the connecting plate. A connecting column is fixedly connected to the other end of the fixed plate. A scraper is fixedly connected to the other end of the connecting column.

[0012] With the above technical solution, after the motor starts, it drives the rotating rod to rotate, which in turn causes the connecting plate, fixing plate, connecting column and scraper to move together. The scraper closely adheres to the inner wall of the tank and can effectively scrape off the attached residue during the rotation process, avoiding the accumulation of residue and corrosion of the tank. In addition, the linkage design of each component ensures a comprehensive cleaning range and stable cleaning force, which greatly improves the efficiency and effect of tank cleaning.

[0013] As a further description of the above technical solution:

[0014] The coordinating mechanism includes a water pipe, the outside of which is fixedly connected to the inner wall of the tank, and the other end of which is fixedly connected to a connecting ring. The outside of the connecting ring is rotatably connected to the outside of the rotating rod. The inner wall of the fixed plate has a water outlet one, and the outside of the scraper has a water outlet two.

[0015] Through the above technical solution, water is introduced through the water pipe, and the connecting ring ensures that the water supply is not affected when the rotating rod rotates. Water flows in through the water pipe and is sprayed out through the water outlet one of the fixed plate and the water outlet two of the scraper. When the cleaning mechanism is running, the water and the scraping action of the scraper work together to rinse the inner wall of the tank in all directions, improve the cleaning effect, reduce residue, and extend the service life of the tank.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the tank is fixedly connected with an anti-corrosion coating, and the outer surfaces of the plurality of rotating rods are slidably connected to the inner wall of the anti-corrosion coating.

[0018] Through the above technical solution, the anti-corrosion coating acts like a solid shield, tightly adhering to the inner wall of the tank, effectively resisting liquid corrosion and extending the service life of the tank. Multiple rotating rods slide smoothly on its inner wall, ensuring the normal operation of cleaning and other mechanisms without damaging the integrity of the anti-corrosion coating, ensuring that the tank always has good anti-corrosion performance during long-term use.

[0019] As a further description of the above technical solution:

[0020] The transmission component includes connecting blocks. The two connecting blocks are externally fixedly connected to the inner wall of the second connecting pipe. The inner wall of the connecting blocks is provided with multiple sliding grooves. A sliding plate is slidably connected to the inner wall of the sliding groove. A baffle is fixedly connected to the bottom of the sliding groove. A storage box is fixedly connected to the top of the second connecting pipe.

[0021] Through the above technical solution, the connecting block provides a stable mounting base for the slide plate and baffle, and the sliding groove provides precise guidance for the slide plate to slide. When the piston drives the baffle to slide, the slide plate moves synchronously within the sliding groove, precisely controlling the opening and closing of the storage tank channel and the reagent flow rate. This structural design ensures stable and accurate reagent transfer, avoids reagent leakage or waste, and provides a reliable guarantee for the precise adjustment of the pH value of the liquid in the tank.

[0022] As a further description of the above technical solution:

[0023] The baffle is slidably connected to the inner wall of the connecting block, and the bottom of the second connecting pipe is fixedly connected to the inner wall of the tank.

[0024] Through the above technical solution, the sliding design of the baffle on the inner wall of the connecting block, in conjunction with the sliding plate, enables flexible control of reagent delivery, ensuring stable and leak-free transmission. The bottom of the connecting pipe is firmly fixed to the inner wall of the tank, creating a stable channel for reagents from the storage tank to the tank, enabling the extracted reagents to be accurately and efficiently delivered into the tank, ensuring smooth liquid pH adjustment, and providing reliable material transmission guarantee for the entire adjustment system.

[0025] As a further description of the above technical solution:

[0026] The bottom of the rotating rod is fixedly connected to multiple guide plates, the bottom of the guide plates is slidably connected to the inner wall of the tank, and a spring is slidably connected to the outside of the connecting column;

[0027] Through the above technical solution, the guide plate at the bottom of the rotating rod can guide the cleaning water to be evenly distributed on the inner wall of the tank when rotating, avoiding the water flow from concentrating and scouring local areas, thus enhancing the cleaning effect. The spring sleeve on the outside of the connecting column allows the scraper to adapt to different curvatures of the inner wall of the tank, ensuring stable scraping force and effectively removing stubborn residues. The two work together to improve the cleaning efficiency and quality of the tank.

[0028] As a further description of the above technical solution:

[0029] The bottom of the tank is provided with a discharge port, and a support is fixedly connected to the bottom of the tank;

[0030] The above technical solution facilitates the rapid and smooth discharge of the regulated liquid from the tank, precisely controlling the output volume and flow rate of the liquid to meet subsequent usage requirements. The fixed support at the bottom provides stable support for the tank, ensuring its balance during liquid storage, pH adjustment, and cleaning operations, preventing shaking and tipping, and enhancing the safety and stability of equipment operation.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the reagent delivery volume can be adjusted in real time according to the change of liquid concentration through the linkage of the pneumatic cylinder and the piston. The cooperation of the slide plate and the baffle in the material transmission component realizes the fine control of reagent flow rate to meet the needs of different working conditions. Its automated operation greatly improves the adjustment efficiency, reduces the manpower input, and the fully enclosed transmission path prevents reagent leakage, which not only ensures production safety, but also reduces material loss and significantly improves production efficiency and reliability.

[0033] 2. In this utility model, after the tank is used up, the motor drives the scraper to remove the residue on the inner wall, which can effectively prevent the residue from causing corrosion and pollution to the tank. The water pipe in the coordination mechanism injects water and sprays it out through outlet one and outlet two. Together with the scraper, it forms a double cleaning effect, which not only improves the cleaning efficiency, but also cleans the tank more thoroughly, thereby extending the service life of the tank and reducing the equipment maintenance cost.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Reference Figures 1 to 3 The present invention provides an embodiment of a pH regulating tank with anti-corrosion function, comprising a tank body 1, which serves as the core container for holding the liquid to be regulated. The top of the tank body is fixedly connected to an regulating mechanism 2 and a cleaning mechanism 3, which respectively undertake the key tasks of regulating the pH value of the liquid and cleaning the tank body. The discharge port 7 is fixedly connected to the inner wall of the tank body 1 to facilitate the discharge of the regulated liquid. The coordinating mechanism 4 installed on the inner wall of the cleaning mechanism 3 cooperates with the cleaning mechanism 3 to improve the cleaning efficiency and effect.

[0043] The regulating mechanism 2 includes a fixing block 23. Multiple fixing blocks 23 are firmly fixed to the top of the tank 1, providing reliable support for other components of the regulating mechanism 2. The pneumatic cylinder 21, which is fixedly connected to the inner wall of two fixing blocks 23, is the power source of the regulating mechanism 2. When an abnormal liquid concentration is detected in the tank 1 and the pH value needs to be adjusted, the pneumatic cylinder 21 is activated. Its driving end drives the piston 22 to slide back and forth in the first connecting pipe 24. The sliding of the piston 22 is transmitted to the second connecting pipe 26 through the first connecting pipe 24, so that the baffle 254 in the second connecting pipe 26 slides synchronously, thereby opening the channel of the storage tank 255, accurately extracting the reagent in the storage tank 255, and feeding it into the tank 1 under the continuous action of the pneumatic cylinder 21, thus achieving efficient adjustment of the liquid pH value.

[0044] Specifically, when the pH detection device in tank 1 reports an abnormal concentration, the adjustment process is quickly initiated. The pneumatic cylinder 21 is activated, and its powerful force drives the piston 22 to slide stably within the connecting pipe 24. This sliding action, through the connection between the connecting pipe 24 and the connecting pipe 26, precisely moves the baffle 254. After the baffle 254 slides open, the passage between the storage tank 255 and tank 1 is unobstructed. Under the pressure generated by the pneumatic cylinder 21, the reagent in the storage tank 255 is quickly and accurately extracted. As the pneumatic cylinder 21 continues to move, the reagent is stably fed into tank 1, where it is fully mixed with the liquid, quickly and effectively adjusting the pH value of the liquid to ensure that the liquid reaches the required concentration standard.

[0045] The connecting block 251 of the transmission component 25 is fixed to the inner wall of the connecting pipe 26, providing an installation base for components such as the slide plate 252 and the baffle 254. The groove 253 on the inner wall of the connecting block 251 provides a sliding track for the slide plate 252. The sliding of the slide plate 252 in the groove 253 can precisely control the flow rate and on / off of the reagent. The baffle 254 at the bottom of the groove 253 cooperates with the slide plate 252. Driven by the piston 22, it realizes the extraction and feeding operation of the reagent in the storage tank 255, ensuring the accuracy and stability of the reagent transmission. The baffle 254 slides on the inner wall of the connecting block 251. Its sliding stability and sealing directly affect the reagent transmission effect. The bottom of the connecting pipe 26 is fixed to the inner wall of the tank 1, ensuring that the reagent can be smoothly and stably transported into the tank 1, providing a reliable guarantee for the adjustment of the liquid pH value.

[0046] Specifically, when piston 22 moves, it drives baffle 254 to slide stably on the inner wall of connecting block 251, cooperating with slide plate 252 to precisely control reagent transmission. Slide plate 252 slides in slide groove 253, like a precise valve switch, controlling reagent flow. The bottom of connecting pipe 26 is fixed to the inner wall of tank 1 to ensure that the reagent is delivered stably and accurately into tank 1, ensuring smooth adjustment of liquid pH value.

[0047] Reference Figure 1 , Figure 4 and Figure 5 The cleaning mechanism 3 uses a motor 36 as its power core. The motor 36 is fixed to the top of the tank 1. When the tank 1 is finished using, the motor 36 is turned on, and its drive end drives the rotating rod 37 to rotate at high speed. When the rotating rod 37 rotates, multiple connecting plates 35 fixed to its outside move accordingly. The connecting plates 35 further drive the fixed plate 31, connecting column 32, and scraper 34 to perform circumferential motion. During the movement, the scraper 34 closely adheres to the inner wall of the tank 1, scraping off the residue adhering to the inner wall, effectively reducing the risk of corrosion and contamination of the tank 1 by the residue. The water pipe 41 of the coordinating mechanism 4 is fixed to the inner wall of the tank 1 and is used to transport cleaning water. The water pipe 41 is rotatably connected to the rotating rod 37 through the connecting ring 42. This design ensures that the water flows smoothly when the rotating rod 37 rotates. The connection of pipe 41 is not affected. When the cleaning mechanism 3 is working, water is injected into pipe 41. The water passes through the connecting ring 42, the water outlet 43 on the inner wall of the fixed plate 31 and the water outlet 44 on the outside of the scraper 34, and is evenly sprayed on the inner wall of the tank 1. The water flow, combined with the scraping of the scraper 34, forms a dual cleaning effect of flushing and scraping, which greatly improves the cleaning efficiency and effectively protects the service life of the tank 1. The anti-corrosion coating 5 on the inner wall of the tank 1 is like a strong protective armor that can resist the corrosion of various liquids in the tank and protect the structural integrity of the tank 1 from the root. The external of multiple rotating rods 37 is slidably connected to the inner wall of the anti-corrosion coating 5, which not only ensures the smooth rotation of the rotating rods 37, but also does not cause wear to the anti-corrosion coating 5, ensuring the long-term effectiveness of the anti-corrosion function.

[0048] Specifically, the cleaning mechanism 3 uses a motor 36 to drive a rotating rod 37, which in turn drives the connecting plate 35, the fixing plate 31, the connecting column 32, and the scraper 34 to move in a circular motion. The scraper 34 scrapes off residues against the inner wall of the tank 1, reducing the risk of corrosion and contamination. The water pipe 41 of the coordination mechanism 4 delivers cleaning water, which is sprayed through the connecting ring 42, the first water outlet 43, and the second water outlet 44. This, together with the scraper 34, forms a double cleaning process, improving efficiency. The anti-corrosion coating 5 on the inner wall of the tank 1 resists liquid corrosion, ensuring the integrity of the tank structure. The rotating rod 37 is slidably connected to the inner wall of the anti-corrosion coating 5, ensuring smooth rotation without damaging the coating and ensuring the long-lasting effectiveness of the anti-corrosion function.

[0049] Reference Figure 1 Figure 2 and Figure 4The guide plate 38 at the bottom of the rotating rod 37 guides the flow direction of the cleaning water when the rotating rod 37 rotates, making the water flow more evenly distributed on the inner wall of the tank 1 and enhancing the cleaning effect. The spring 33 outside the connecting column 32 has an elastic buffering effect, which allows the scraper 34 to adaptively conform to the different curvatures of the inner wall of the tank 1. No matter how the shape of the inner wall changes, the scraper 34 can make close contact to ensure the scraping effect. The discharge port 7 at the bottom of the tank 1 is the discharge channel of the regulated liquid. Its design ensures that the liquid can flow out quickly and smoothly. The bracket 6 fixedly connected to the bottom of the tank 1 provides stable support for the tank 1, ensuring that the entire pH adjustment tank remains stable during operation and is not affected by external factors.

[0050] Specifically, the cleaning mechanism 3 is powered by the motor 36, which allows the scraper 34 to scrape away residue on the inner wall of the tank 1, reducing corrosion and pollution. The coordinating mechanism 4 sprays water evenly and works with the scraper 34 for efficient cleaning. The anti-corrosion coating 5 protects the tank structure. The rotating rod 37 is slidably connected to the inner wall of the coating, ensuring rotation without damaging the coating and maintaining its anti-corrosion effect for a long time.

[0051] Working principle: When an abnormal pH value is detected in the liquid inside tank 1, the regulating mechanism 2 responds immediately. The pneumatic cylinder 21 is activated, and its drive end drives the piston 22 to slide back and forth in the first connecting pipe 24. The sliding of the piston 22 causes the baffle 254 in the second connecting pipe 26 to move synchronously. Through the sliding of the slide plate 252 in the slide groove 253, the channel of the storage tank 255 is opened, and the regulating reagent is extracted and accurately fed into tank 1, realizing rapid pH adjustment.

[0052] After use, cleaning mechanism 3 begins operation. Motor 36 drives rotating rod 37 to rotate, causing connecting plate 35, fixing plate 31, connecting column 32, and scraper 34 to thoroughly scrape the inner wall of tank 1, removing residual substances. Simultaneously, coordinating mechanism 4 activates, water pipe 41 fills the tank, and water flows through connecting ring 42, outlet 1 43, and outlet 2 44 into tank 1. Combined with the scraping action of scraper 34, this creates a dual cleaning effect of flushing and scraping. The guide plate 38 at the bottom of rotating rod 37 guides the water flow, ensuring more even cleaning. The anti-corrosion coating 5 on the inner wall of tank 1 continuously protects the tank from liquid corrosion. The coordinated operation of all mechanisms ensures the efficient operation and long-term use of the pH adjusting tank.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
