Description

Technical Field

[0001] This utility model relates to the field of waste acid treatment technology, and more specifically, to a waste acid safe treatment device. Background Technology

[0002] Waste acid water is highly corrosive. If discharged directly without treatment, it will corrode pipes and structures. If discharged into water bodies, it will change the pH value of the water, interfere with and affect the growth of aquatic organisms and fishery production. Therefore, waste acid needs to be neutralized before it can be discharged. When neutralizing waste acid water, a waste acid safety treatment device is required.

[0003] In existing treatment devices, alkaline solutions are generally required for neutralizing waste acid. Different weights of waste acid require different weights of alkaline solution. However, existing devices cannot effectively weigh the waste acid and alkaline solution, forcing workers to manually weigh them. While this method effectively mixes and neutralizes the waste acid and alkaline solution, the weighing process is time-consuming and labor-intensive. This not only reduces the neutralization efficiency and effectiveness but also increases the workload of workers. Furthermore, manual weighing poses certain safety hazards, reducing the overall practicality and safety of the device.

[0004] Compared with Chinese Patent Publication No. CN219885790U, this utility model provides a waste acid safe treatment device, relating to the field of waste acid treatment technology. It includes a treatment tank with a concave frame plate fixed to its outer wall. A safety maintenance mechanism is located inside the concave frame plate. The safety maintenance mechanism includes two transmission screws arranged sequentially from left to right inside the concave frame plate. Each transmission screw has a servo reduction motor coaxially connected to its top end. A concave collar bracket is threadedly connected to the outer wall of the transmission screws. A linkage bracket is welded to the top of the concave collar bracket near its center. Through this safety maintenance mechanism, the transmission screws drive the concave collar bracket upwards under the action of the threads. Maintenance personnel do not need to enter the treatment tank to repair parts, thus exposing the stirring rod to the outside for greater maintenance space, reducing the risk of injury to maintenance personnel, and improving safety during maintenance.

[0005] The above solution facilitates maintenance and repair of the equipment, but it still lacks an effective weighing structure. Weighing waste acid and alkaline solutions still requires manual operation, which reduces the overall practicality and safety of the equipment and fails to solve the problems mentioned in the background section.

[0006] Therefore, those skilled in the art have provided a waste acid safe treatment device to solve the problems mentioned in the background art. Utility Model Content

[0020] This waste acid safety treatment device, equipped with an adjustment component, a stirring component, and a weighing and metering component, allows for the neutralization of waste acid. First, the waste acid is added to the waste acid cylinder, followed by an alkaline solution to the alkaline cylinder.

This effectively improves the neutralization efficiency and effect of waste acid and reduces the workload of the staff. After the waste acid and alkaline solution enter the processing tank, the stirring component starts to operate. At this time, the stirring component can effectively mix and stir the waste acid and alkaline solution, thereby effectively neutralizing the waste acid. After the waste acid is neutralized, the first solenoid valve opens, and the solution inside the processing tank will be discharged through the drain pipe, thus effectively processing the waste acid. By adjusting the component settings, the closing cover can be opened and closed conveniently and effectively, making it easy for the staff to clean the inside of the processing tank and the stirring component, effectively improving the overall practicality of the device.

[0028] 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.

[0029] Please see Figure 1 - Figure 5 As shown, this embodiment provides a waste acid safety treatment device, including a base 1, and further comprising:

[0030] The processing cylinder 2 is located above the base 1. The bottom of the processing cylinder 2 is connected to the drain pipe 11 through the first solenoid valve 10. The top of the processing cylinder 2 is provided with a closing cover 3.

[0031] The rear plate 4 is fixedly connected to the rear end surface of the base 1;

[0032] The adjustment component is located on the upper surface of the rear plate 4;

[0033] Side plates 6 are respectively set on both sides of the outer wall of the base 1. Above the two side plates 6, there are waste acid cylinder 7 and alkaline cylinder 9 respectively. The exterior of waste acid cylinder 7 and alkaline cylinder 9 are fixedly connected to the upper surface of side plate 6 through support frame 8. The bottom of waste acid cylinder 7 is connected to the interior of treatment cylinder 2 through second solenoid valve 12 and bellows 14. The bottom of alkaline cylinder 9 is connected to the interior of treatment cylinder 2 through third solenoid valve 13 and bellows 14.

[0034] The stirring component is located on the upper surface of the closed cover 3;

[0035] The weighing and quantitative components are symmetrically arranged on the upper surface of the base 1.

[0036] The working principle is as follows: When neutralization of waste acid is required, the waste acid is first added to the waste acid cylinder 7, and then the alkaline solution is added to the alkaline cylinder 9. At this time, the second solenoid valve 12 opens, and the waste acid in the waste acid cylinder 7 enters the processing cylinder 2. When the waste acid enters the processing cylinder 2, the processing cylinder 2 will move downwards due to the weight of the waste acid. During the downward movement of the processing cylinder 2, the weighing and metering component can effectively weigh the waste acid inside the processing cylinder 2. When the waste acid has completely entered the processing cylinder 2, the third solenoid valve 13 opens, and the alkaline solution in the alkaline cylinder 9 will simultaneously enter the processing cylinder 2. When the alkaline solution enters the processing cylinder 2, the weighing and metering component can effectively weigh the alkaline solution inside the processing cylinder 2. When the weight of the alkaline solution inside the processing cylinder 2 reaches the specified standard, the weighing and metering component will transmit a signal to the control... The controller then controls the third solenoid valve 13 to close, allowing for quantitative processing of the alkaline solution without requiring manual weighing and mixing of the waste acid and alkaline solution. This effectively improves the neutralization efficiency and reduces the workload of the staff. Once the waste acid and alkaline solution have entered the processing cylinder 2, the stirring component starts operating. This component effectively mixes and stirs the waste acid and alkaline solution, thus effectively neutralizing the waste acid. After neutralization, the first solenoid valve 10 opens, and the solution inside the processing cylinder 2 is discharged through the drain pipe 11, effectively processing the waste acid. By adjusting the component settings, the closing cover 3 can be opened and closed conveniently and effectively, facilitating cleaning of the inside of the processing cylinder 2 and the stirring component, thus improving the overall practicality of the device.

[0037] To effectively open the closed cover 3, facilitating cleaning of the interior of the processing cylinder 2 and the stirring assembly, the adjustment assembly includes an adjustment plate 5 fixedly connected to the upper surface of the rear plate 4. A first motor 15 is fixedly connected to the upper surface of the adjustment plate 5. The output shaft of the first motor 15 is fixedly connected to a threaded rod 22 via a coupling. The bottom end of the threaded rod 22 is rotatably connected to the bottom end of the inner part of the adjustment plate 5. A threaded block 23 is threadedly connected to the outer part of the threaded rod 22. A guide groove for the threaded block 23 to move is provided on the front surface of the adjustment plate 5. A fixing frame 24 is fixedly connected to the front surface of the threaded block 23. The outer part of the fixing frame 24 is fixedly connected to the outer part of the closed cover 3. When it is necessary to open the closed cover 3, the first motor 15 starts running. At this time, the first motor 15 drives the threaded rod 22 to rotate synchronously, and the threaded block 23 moves synchronously outside the threaded rod 22, driving the fixing frame 24 to move synchronously. The fixing frame 24 then drives the closed cover 3 to move synchronously. At this time, the closed cover 3 can be opened conveniently and effectively, facilitating cleaning of the interior of the processing cylinder 2 and the exterior of the stirring assembly.

[0038] Considering that it is necessary to improve the sealing between the closed cover 3 and the treatment cylinder 2 during the neutralization process of waste acid, a rubber sealing ring 25 is bonded to the inner wall of the closed cover 3. The setting of the rubber sealing ring 25 can effectively improve the sealing between the closed cover 3 and the treatment cylinder 2, thereby preventing the liquid inside the treatment cylinder 2 from splashing to the outside.

[0039] To effectively improve the neutralization efficiency of waste acid, the stirring assembly includes a second motor 16 fixedly connected to the upper surface of the closed cover 3. The output shaft of the second motor 16 is fixedly connected to a rotating rod 17 via a coupling. A turntable 18 is fixedly connected to the bottom end of the rotating rod 17. Stirring rods 19 are evenly spaced on the outside of the rotating rod 17. When the waste acid and alkaline solution are added into the treatment cylinder 2, the second motor 16 starts to run. At this time, the second motor 16 drives the rotating rod 17 to rotate synchronously, and the rotating rod 17 drives the stirring rods 19 to rotate synchronously. At this time, the waste acid and alkaline solution inside the treatment cylinder 2 can be mixed and stirred by the stirring rods 19, thereby effectively improving the neutralization efficiency and effect of waste acid.

[0040] To effectively weigh waste acid and alkaline solutions, the weighing and quantitative assembly includes weighing sensors 28 symmetrically arranged on the upper surface of the base 1. Multiple abutment rods 29 are fixedly connected to the upper surfaces of both weighing sensors 28. Multiple damping rods 26 are fixedly connected to the upper surface of the base 1. Moving plates 21 are fixedly connected to the telescopic ends of the damping rods 26. The exterior of the moving plates 21 is fixedly connected to the exterior of the processing cylinder 2. Return springs 27 are sleeved on the exterior of each damping rod 26, and these return springs 27 abut against the moving plates 21 and the base 1. L-shaped plates 30 are symmetrically arranged on the exterior of the processing cylinder 2. Lower pressure plates 31 are fixedly connected to the bottom of each of the two L-shaped plates 30. When waste acid enters the processing cylinder 2, its weight causes the processing cylinder 2 to move downwards. At this time, the processing cylinder 2 will drive the moving plates 21 to move synchronously. During the movement of the moving plates 21, the damping rods 26 and return springs 27 will be simultaneously squeezed. The processing cylinder 2 will also drive the L-shaped plates 30 and... The lower pressure plate 31 moves synchronously. When the bottom of the lower pressure plate 31 abuts against the top of the contact rod 29, the weight of the waste acid inside the treatment cylinder 2 can be weighed by the weighing sensor 28. After the waste acid is added, the third solenoid valve 13 opens, and the alkaline solution inside the alkaline cylinder 9 enters the treatment cylinder 2. During the process of adding the alkaline solution into the treatment cylinder 2, the weighing sensor 28 can effectively weigh the alkaline solution. When the weight of the alkaline solution reaches the standard, the weighing sensor 28 will transmit a signal to the controller, and the controller will then control the third solenoid valve 13 to close. At this time, the waste acid and alkaline solution can be quantitatively processed without the need for manual weighing by the staff, which effectively improves the neutralization efficiency and effect of the waste acid, reduces the workload of the staff, and improves the overall practicality and safety factor of the device. When the solution inside the treatment cylinder 2 is completely discharged, the reset spring 27 resets, which will drive the moving plate 21 and the treatment cylinder 2 to move synchronously.

[0041] In addition, in order to effectively extend the service life of the damping rod 26 and the return spring 27, each of the damping rods 26 is fitted with a bellows cover 20. The two ends of the bellows cover 20 are fixedly connected to the opposite side of the moving plate 21 and the base 1, respectively. By setting the bellows cover 20, the damping rod 26 and the return spring 27 can be effectively protected from dust and water, thereby effectively preventing the return spring 27 and the damping rod 26 from rusting and extending their service life. At the same time, it will not affect the normal use of the return spring 27 and the damping rod 26.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
