Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically a wastewater treatment agent dissolution device for wastewater treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. This process involves a variety of treatment methods, including physical, chemical and biological methods. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] For example, the utility model disclosed in publication (announcement number): CN221714027U, provides a wastewater treatment agent dissolving device for wastewater treatment, relating to the field of wastewater treatment technology. It includes a screening mechanism, with a stirring mechanism fixedly installed on one side of the outer wall of the screening mechanism. The stirring mechanism includes a motor. In this utility model, under the action of the screening mechanism, the powder is first poured into the screening box. Then, a vibrator drives the screening box to vibrate, causing clumps of wastewater treatment agent to slide into the collection tank. This avoids large clumps of wastewater treatment agent failing to dissolve fully inside the stirring box, affecting the uniform diffusion of the drug. It also prevents wear or blockage of related components, which could lead to equipment malfunction and reduced service life. The radar level gauge can monitor the amount of liquid inside the stirring box in real time and promptly alerts users to add liquid when it is nearly depleted, preventing spraying work from being interrupted due to insufficient liquid and reducing work efficiency.

[0004] The aforementioned utility model device has a sieving structure to screen out and collect the lumpy part of the medicine powder. However, when using the device, the lumpy medicine powder needs to be crushed separately before being put into the medicine tank. At the same time, it is not convenient to clean the holes of the sieving mechanism when they are blocked. In addition, the stirring process of the medicine powder and water in the device is only carried out in the vertical direction, and the stirring effect needs to be improved. Utility Model Content

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] This invention involves feeding wastewater treatment powder into the screening box through a gap between the top plate and the screening box. The powder, if clumped, is sieved through several screening holes on the screening plate surface. A hydraulic cylinder is controlled to move a movable plate vertically, causing the movable plate and insert pins to contact the screening plate. The conical structure at the bottom of the insert pins and the pressure between the movable plate and the screening plate break up the clumped powder, allowing it to dissolve through the screening holes into the dissolving tank.

The two sides of the screening plate 9 are slidably sleeved on the outer side of each positioning rod 8. Several screening holes 10 are opened through the surface of the screening plate 9 in a vertical direction. A movable plate 11 parallel to the screening holes 10 is arranged above the screening box 3. Several pins 12 are fixedly connected to the bottom of the movable plate 11. Each pin 12 is slidably inserted into the corresponding screening hole 10.

[0020] In this embodiment, the end of the connecting shaft 5 away from the motor 4 is rotatably connected to the inner wall of the dissolving tank 2, and the outer side of the other end of the connecting shaft 5 is rotatably connected to the side wall of the dissolving tank 2. A sealing ring is provided between the outer side of the connecting shaft 5 and the side wall of the dissolving tank 2. Several vertical rods 13 are fixedly connected to the top of the screening box 3, and the top of the vertical rods 13 is fixedly connected to the bottom of the top plate 14. A hydraulic cylinder 15 is fixedly connected to the center of the top of the top of the top plate 14. The movable end of the hydraulic cylinder 15 slides through the center of the top plate 14 and is fixedly connected to the center of the top of the movable plate 11. Each pin 12 has a conical structure at its bottom. A spring is sleeved on the outer side of each positioning rod 8, and each spring is connected to the... The top of the positioning plate 7 and the bottom of the screening plate 9 are fixedly connected. Each stirring component 6 includes several stirring rods 61, and two adjacent stirring rods 61 are fixedly connected to the two ends of the connecting rod 62 respectively. A collar 63 is slidably sleeved on the outer side of the middle of each connecting rod 62, and several horizontal stirring rods 64 are fixedly connected to the outer side of each collar 63.

A sealing ring is provided at the connection between the outer side of the connecting shaft 5 and the side wall of the dissolution tank 2 to ensure a sealing effect.

[0022] The working principle of this utility model is as follows: Wastewater treatment powder is fed into the screening box 3 through the space between the top plate 14 and the screening box 3. The powder, which has clumps, is sieved through several screening holes 10 on the surface of the screening plate 9. The hydraulic cylinder 15 is controlled to move the movable plate 11 vertically, causing the movable plate 11 and the insert pins 12 to contact the screening plate 9. The conical structure at the bottom of the insert pins 12 and the pressure from the movable plate 11 and the screening plate 9 break up the clumps of powder, allowing the broken powder to enter the dissolving tank 2 through the screening holes 10 for dissolution. Simultaneously, when the movable plate 11 contacts the screening plate 9, the insert pins 12, which engage with the screening holes 10, clean each screening hole 10, preventing large particles of powder from damaging them. To prevent blockage, water is injected into the dissolving tank 2 through the water inlet to mix with the medicine powder. The motor 4 is controlled to drive the connecting shaft 5 to rotate, thereby mixing the medicine powder and water through multiple stirring components 6 to improve the dissolution effect of the medicine powder. Each stirring component 6 includes multiple stirring rods 61 connected by connecting rods 62.
