Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a water treatment agent slow-release mechanism. Background Technology

[0002] Wastewater treatment refers to the process of treating wastewater using physical, chemical, and biological methods to meet specific water quality standards, enabling it to be discharged into a water body or reused. Wastewater treatment is widely used in construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, becoming an indispensable part of daily life. One step in wastewater treatment involves using chemicals. When using chemicals to treat wastewater, chemicals need to be added to the wastewater treatment equipment through a chemical dosing system.

[0003] A search revealed that patent CN221565845U discloses a water treatment agent slow-release mechanism. This mechanism involves placing the slow-release mechanism into water, adjusting the depth using a screw to ensure water flows into the inner cylinder along a baffle. At this point, the disc-shaped agent tablets at the top of the inner cylinder do not contact the water. After the lower disc-shaped agent tablets dissolve, the upper disc-shaped agent tablets fall into the water to continue dissolving, avoiding frequent additions and extending the agent's effective time. However, this mechanism has the following drawbacks in practical application: once the agent tablets have dissolved, the entire mechanism needs to be removed from the water before adding more tablets, resulting in low automation. Furthermore, the dissolution rate of the agent tablets is uncontrollable, leading to unpredictable mixing between the tablets and wastewater. Therefore, further improvements are needed.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, a water treatment agent slow-release mechanism is disclosed, comprising a mixing tank 1, a feeding assembly 2 installed on one side of the top wall of the mixing tank 1, and the feeding assembly 2 including a material cylinder 21, the bottom end of the material cylinder 21 being funnel-shaped, and the inside of the material cylinder 21 being filled with powdered water treatment agent, a feeding pipe 22 fixedly connected to the bottom end of the material cylinder 21, the feeding pipe 22 being fixedly connected to the top wall of the mixing tank 1, a water supply pipe 3 fixedly fixed to the top of the side wall of the mixing tank 1, a drain pipe 7 fixedly fixed to the bottom end of the side wall of the mixing tank 1 away from the water supply pipe 3, and a second motor 4 fixedly fixed to the upper surface of the mixing tank 1. A second vertical shaft 5 is fixed at the bottom output end. The second vertical shaft 5 passes through the top and bottom walls of the mixing tank 1 and is rotatably connected to the mixing tank 1 through a sealed bearing. A stirring blade 6 is fixed on the surface of the second vertical shaft 5 and the stirring blade 6 is located inside the mixing tank 1. A sleeve 8 is rotatably connected to the surface of the drain pipe 7 away from the mixing tank 1 through a sealed bearing. A horizontal pipe 9 is fixed on the side wall of the sleeve 8. The sleeve 8 and the bottom surface of the second vertical shaft 5 are connected together by a linkage assembly 10. A PLC controller 13 is installed on the outer wall of the mixing tank 1. A mounting plate 14 is fixed at the bottom of the outer wall of the mixing tank 1.

[0022] In this embodiment, the PLC controller 13 is a Siemens S7-200 programmable controller, and the mechanism is controlled by the PLC controller 13.

[0023] A feeding port 26 is provided on one side of the top wall of the material cylinder 21. A first motor 23 is fixed in the middle of the top wall of the material cylinder 21, and a first vertical shaft 24 is fixed at the bottom output end of the first motor 23. A spiral blade 25 is fixed on the bottom surface of the first vertical shaft 24. The spiral blade 25 is located inside the feeding pipe 22. The first motor 23 is electrically connected to the PLC controller 13.

[0024] The PLC controller 13 controls the first motor 23 to drive the first vertical shaft 24 to rotate, which in turn drives the spiral blade 25 to rotate inside the feed pipe 22. The spiral blade 25 pushes the powdered medicine stored in the feed cylinder 21 out of the feed pipe 22, allowing the medicine to enter the mixing tank 1, thus realizing automatic medicine addition. The operator only needs to periodically add medicine into the feed cylinder 21 through the addition port 26.

[0025] A first solenoid valve 31 is fixedly connected to the middle of the water supply pipe 3, and a second solenoid valve 71 is fixedly connected to the middle of the drain pipe 7. Both the first solenoid valve 31 and the second solenoid valve 71 are electrically connected to the PLC controller 13.

[0026] In this embodiment, the water supply pipe 3 is connected to the tap water pipe. The PLC controller 13 can control the opening and closing of the first solenoid valve 31 and the second solenoid valve 71. When the first solenoid valve 31 is opened, water is added to the mixing tank 1 through the water supply pipe 3. When the second solenoid valve 71 is opened by the PLC controller 13, the liquid inside the mixing tank 1 can be discharged along the drain pipe 7.

[0027] Liquid level sensors 12 are installed at the bottom and top of the inner wall of the mixing tank 1, and the liquid level sensors 12 are electrically connected to the PLC controller 13.

[0028] In this embodiment, the liquid level sensor 12 adopts a capacitive NI-GCT-NE-EC01 sensor. The liquid level sensor 12 can monitor the liquid level inside the mixing tank 1 in real time and feed the monitoring information back to the PLC controller 13.

[0029] A heater 11 is fixedly connected to the inner wall of the mixing tank 1, and the heater 11 is electrically connected to the PLC controller 13.

[0030] Heater 11 can heat the water in mixing tank 1, so that the agent can mix with the water more quickly.

[0031] The linkage assembly 10 includes a driving pulley 101 fixed to the bottom surface of the second vertical shaft 5 and a driven pulley 102 fixed to the outer wall of the sleeve 8. The driving pulley 101 and the driven pulley 102 are both fitted with a belt 103.

[0032] Under the transmission of belt 103, the driving pulley 101 can drive the driven pulley 102 to rotate. Therefore, when the second motor 4 drives the second vertical shaft 5 and the stirring blade 6 to rotate, it can also drive the sleeve 8 to rotate through the linkage component 10, thereby driving the horizontal tube 9 to rotate.

[0033] Working Principle: In use, the mechanism is installed on top of the sewage treatment tank via the mounting plate 14, with the horizontal pipe 9 positioned above the treatment tank. Powdered chemicals are then added into the feed cylinder 21 through the inlet 26. When the level sensor 12 at the bottom of the mixing tank 1 detects that the liquid level inside the mixing tank 1 is lower than its own level, the PLC controller 13 controls the first solenoid valve 31 to open. At this time, the water supply pipe 3, connected to the tap water pipe, adds water into the mixing tank 1. When the liquid level reaches the position of the level sensor 12 at the top of the mixing tank 1, the PLC controller 13 controls the first solenoid valve 31 to close. Simultaneously, the PLC controller 13 controls the first motor 23 to drive the spiral blade 25 to rotate at a specified angle, thereby quantitatively discharging the powdered chemicals from the feed cylinder 21 into the mixing tank. In step 1, the PLC controller 13 then controls the second motor 4 and the heater 11 to start. The second motor 4 drives the stirring blade 6 to rotate, realizing the stirring and mixing of water and chemicals. After the mixing is completed, the PLC controller 13 controls the heater 11 to stop and opens the second solenoid valve 71. At this time, the mixed liquid will be discharged from the drain pipe 7 and discharged along the sleeve 8 and the horizontal pipe 9. During this process, the sleeve 8 and the horizontal pipe 9 will rotate under the drive of the linkage component 10, so that the discharged liquid chemicals will spread over a wider range and increase the contact area between the chemicals and the sewage in the sewage tank.
