Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to the TMAH wastewater treatment device. Background Technology

[0002] Wastewater treatment involves using physical, chemical, and biological methods to purify wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse, thus making full use of water resources.

[0003] TMAH (tetramethylammonium hydroxide) is a commonly used photoresist developer in the electronics industry (such as semiconductor and LCD manufacturing). Its wastewater is characterized by strong alkalinity, high COD, high nitrogen content, and strong biological toxicity, making it difficult to directly degrade using conventional biological treatment. Due to the strong oxidizing properties of ozone (O3), TMAH can be decomposed through direct oxidation or indirect generation of hydroxyl radicals, making it one of the important means of treating this type of wastewater. However, most existing wastewater treatment devices directly add ozone into the treatment chamber when treating wastewater. But during the addition, the ozone and TMAH are not mixed evenly, resulting in a decrease in ozone utilization and greatly affecting the wastewater treatment effect.

[0004] Therefore, we proposed the TMAH wastewater treatment device to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a TMAH wastewater treatment device, which solves the problem mentioned in the background art that most existing wastewater treatment devices directly add ozone into the treatment chamber when treating wastewater, but the ozone and TMAH do not mix evenly during addition, resulting in reduced ozone utilization and greatly affecting the wastewater treatment effect.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution: The TMAH wastewater treatment unit includes a main chamber and an inlet port connected to one side of the main chamber, and also includes: The positioning slide is symmetrically opened on the upper surface of the main body compartment, and the internal sliding slot of the positioning slide is connected to the connecting slide plate; The drive mechanism, located inside one side of the positioning slide, is used to drive and adjust the position of the connecting slide.

Connecting rods are symmetrically arranged on the left and right sides of the connecting slide. The connecting slide has a linkage mechanism inside that cooperates with the connecting rack to drive the connecting rods to rotate. The ozone dosing device is fixed at the center of the upper end face of the ozone dosing device.

[0009] Furthermore, the driving mechanism includes a servo motor and a connecting screw. The servo motor is fixed on one side of the positioning slide groove, and the connecting screw is rotatably connected to the output end of the servo motor and located inside the positioning slide groove. The connecting screw is threadedly connected to the inner side of the connecting slide plate, and the connecting slide plate can slide left and right along the inside of the positioning slide groove.

[0010] Furthermore, the positioning slide rod is fixed inside another set of positioning slide grooves, and the positioning slide rod slides through the inside of the connecting slide plate.

[0011] Furthermore, the linkage mechanism includes a linkage wheel, a drive wheel, a timing belt, and a driven wheel. The linkage wheel is rotatably connected to the left and right sides of the connecting slide plate and meshes with the connecting rack. The drive wheel is fixed to the upper end face of the linkage wheel. The driven wheel is rotatably connected to the inside of the connecting slide plate and the lower end of the driven wheel is fixed to the connecting rod.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a TMAH wastewater treatment device, which has the following beneficial effects: This invention uses a positioning groove to limit the position of the connecting slide plate, preventing it from shifting or wobbling. A drive mechanism then adjusts the connecting slide plate, facilitating subsequent adjustment of the ozone dosing machine's position. This allows for real-time changes in the ozone dosing location, ensuring effective wastewater treatment. Simultaneously, as the connecting slide plate slides, its internal linkage wheel engages with the connecting rack, causing the linkage wheel to rotate. This, in conjunction with the linkage mechanism, allows the connecting rod to rotate at multiple angles, enabling the stirring paddle to evenly mix the wastewater and ozone, ensuring complete TMAH degradation.

[0023] like Figure 1-4 As shown, an embodiment of the TMAH wastewater treatment device proposed in this utility model includes a main chamber 1 and an inlet port 2 connected to one side of the main chamber 1, and further includes: The positioning slide 3 is symmetrically opened on the upper end face of the main body compartment 1. The connecting slide 6 is slidably engaged inside the positioning slide 3. The drive mechanism is set inside one side of the positioning slide 3 and is used to drive and adjust the position of the connecting slide 6. The drive mechanism includes a servo motor 4 and a connecting screw 5. The servo motor 4 is fixed on one side of the positioning slide 3. The connecting screw 5 is rotatably connected to the output end of the servo motor 4 and is located inside the positioning slide 3. The connecting screw 5 is threadedly connected to the inner side of the connecting slide 6, and the connecting slide 6 can slide left and right along the inside of the positioning slide 3. The servo motor 4 can drive the connecting screw 5 to rotate. The connecting screw 5 is threadedly connected to the connecting slide 6. When the connecting screw 5 rotates, the position of the connecting slide 6 can be adjusted. The ozone dosing unit 15 is fixed at the center of the upper end face of the ozone dosing unit 15. Then, in cooperation with the ozone dosing unit 15, the ozone dosing position of the ozone dosing unit 15 is changed in real time, thereby ensuring its subsequent wastewater treatment effect. The output end of the ozone dosing unit 15 is fixed with a conduit 16, and the outer surface of the conduit 16 has several holes and grooves that extend into the main body chamber 1. The conduit 16 can extend into the main body chamber 1, and the outer side of the conduit 16 has several sets of holes and grooves, which can make the ozone addition more uniform. The positioning slide rod 7 is fixed inside another set of positioning slide grooves 3, and the positioning slide rod 7 slides through the inside of the connecting slide plate 6. The positioning slide rod 7 can limit the position of the connecting slide plate 6, which can prevent the connecting slide plate 6 from shifting or shaking, thus affecting the stability of the connecting slide plate 6. A connecting rack 8 is fixed to the upper surface of the main body compartment 1 and located on one side of the positioning groove 3. Connecting rods 13 are symmetrically arranged on the left and right sides of the connecting slide plate 6. A linkage mechanism is provided inside the connecting slide plate 6 and cooperates with the connecting rack 8 to drive the connecting rods 13 to rotate. The linkage mechanism includes a linkage wheel 9, a drive wheel 10, a synchronous belt 11, and a driven wheel 12. The linkage wheel 9 is rotatably connected to the left and right sides of the connecting slide plate 6 and meshes with the connecting rack 8.

The connecting rod 13 is rotatably connected inside the connecting slide plate 6, and the lower end of the driven wheel 12 is fixed to the connecting rod 13. The timing belt 11 is sleeved on the outer surface of the drive wheel 10, and the other end of the timing belt 11 is engaged with the driven wheel 12. The linkage wheel 9 can be engaged with the connecting rack 8 through the provided linkage wheel 9. When the connecting slide plate 6 slides, the linkage wheel 9 can rotate. When the linkage wheel 9 rotates, the driven wheel 12 can be driven to rotate through the drive wheel 10 and the timing belt 11. Thus, the connecting rod 13 will also rotate while the connecting slide plate 6 slides.

[0024] A stirring paddle 14 is fixed to the lower end face of the connecting rod 13, and the stirring paddle 14 is arranged in a spiral shape. The spiral arrangement of the stirring paddle 14 can make the wastewater and ozone evenly mixed. The position of the connecting slide plate 6 can be adjusted by the drive mechanism.
