Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment, and specifically relates to an automatic dosing device for wastewater treatment. Background Technology

[0002] Industrial production processes generate large quantities of complex wastewater. For example, wastewater from the electrolytic salt industry contains mercury; wastewater from the heavy metal smelting industry contains lead and cadmium; wastewater from the electroplating industry contains cyanide and chromium; wastewater from the petroleum refining industry contains phenols; and wastewater from the pesticide manufacturing industry contains various pesticides. Wastewater treatment requires the addition of chemical agents to stabilize the pH value, improve the precipitation of heavy metals and other impurities, or capture other impurities through flocculants. Automatic dosing devices play a crucial role in wastewater treatment processes, enabling precise and automatic addition of chemicals.

[0003] Existing technologies have specifically developed some automatic dosing devices for wastewater treatment. For example, Chinese patent publication number "CN219168278U" discloses "an automatic dosing device for wastewater treatment." This device has a cavity in which the medicine is pre-placed. When the holding tube is inserted into the wastewater under the control of a power source, the float pulls the piston out of the cavity under the action of buoyancy, thereby mixing the medicine in the cavity with the wastewater to achieve the effect of treating the wastewater. This achieves automatic dosing, reduces the workload of workers, and improves the working speed.

[0004] Although the structure includes a cavity where the drug is pre-placed, and when the container tube is inserted into the wastewater under power control, the float pulls the piston out of the cavity, causing the drug to mix with the wastewater and achieve wastewater treatment, thus realizing automatic dosing, the absence of a stirring mechanism for the drug during use leads to insufficient dosing and ultimately fails to effectively treat the wastewater. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an automatic dosing device for wastewater treatment to solve the problems of wastewater treatment.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An automatic dosing device for wastewater treatment includes a wastewater treatment tank. Cylinders are fixedly installed on both sides of the upper end of the wastewater treatment tank. A fixed plate is fixedly installed at the end of each cylinder away from the wastewater treatment tank. A mixing tank is fixedly installed at the center of the end of the fixed plate away from the cylinder output shaft. A cover plate is snapped onto the end of the mixing tank away from the fixed plate. A drive motor is fixedly installed at the end of the cover plate away from the mixing tank. A rotating rod is fixedly installed on the output shaft of the drive motor. Multiple stirring rods are fixedly installed around the outer ring of the rotating rod. A square plate is integrally formed on one side of the fixed plate. A drive motor is fixedly installed at the end of the square plate away from the fixed plate. A threaded rod is fixedly installed on the output shaft of the drive motor. A baffle is threadedly connected to the outer ring of the threaded rod. The baffle is slidably installed inside the fixed plate. A connecting pipe is fixedly installed at the bottom of the fixed plate. A leakage box is fixedly installed at the end of the connecting pipe away from the fixed plate.

[0008] As a preferred technical solution, the cover plate has raised plates integrally formed on both sides of one end near the mixing tank, and grooves are opened inside the raised plates on both sides.

[0009] As a preferred technical solution, grooves are provided inside both sides of the upper end of the mixing tank, and slots are provided inside the grooves on both sides. Springs are fixedly installed inside the slots, and a locking block is fixedly installed at the end of the spring away from the slot. The protruding plate is slidably installed inside the upper end of the mixing tank through the grooves, and the locking block is engaged inside the slot.

[0010] As a preferred technical solution, the output shaft of the drive motor passes through the inside of the cover plate and is fixedly connected to the rotating rod. The stirring rod rotates inside the stirring tank, and the output shaft of the drive motor passes through the square plate and is fixedly connected to the threaded rod.

[0011] As a preferred technical solution, the connection between the mixing tank and the fixed plate is provided with an opening and closing port, and the two sides of the opening and closing port are integrally formed with a limiting plate. The square plate has a storage groove inside, and the baffle is stored inside the storage groove. The two sides of the baffle are slidably installed inside the limiting plate. The baffle has an internal thread inside, and the threaded rod is threadedly connected to the baffle through the internal thread.

[0012] As a preferred technical solution, a circular groove is provided inside the fixing plate below the opening, and a flow port is provided inside the connecting pipe, with the circular groove communicating with the flow port box.

[0013] As a preferred technical solution, the inside of the leak box is provided with a retention groove, which is connected to the flow outlet box. The bottom and outer ring of the leak box are provided with multiple leak holes, which are connected to the retention groove.

[0014] In summary, the present invention has the following main advantages:

[0015] First, the agent is added to the inside of the mixing tank. The cover plate is slidably installed on the mixing tank by the cooperation of the two side protrusions and the two side grooves on the upper end of the mixing tank. The slots on the protrusions and the spring-connected locking blocks in the grooves of the mixing tank engage with each other. This spring and locking block structure can ensure that the cover plate is tightly connected to the mixing tank and prevent the agent from leaking during the mixing process. Then, the drive motor is started. Its output shaft passes through the cover plate and drives the rotating rod to rotate. The multiple stirring rods on the outer ring of the rotating rod rotate accordingly, which fully stirs and mixes the agent in the mixing tank, so that the agent concentration is uniform and the dosing effect is stable.

[0016] Secondly, the output shaft of the drive motor drives the threaded rod to rotate. Since the baffle has an internal thread, the threaded rod is threadedly connected to the baffle through the internal thread. Therefore, when the threaded rod rotates, the baffle will slide along the limiting plate in the storage groove inside the fixed plate. By controlling the rotation direction and number of rotations of the drive motor, the position of the baffle at the opening and closing port can be precisely adjusted, thereby controlling the flow rate of the agent in the mixing tank into the connecting pipe. When the baffle moves to the appropriate position, the agent flows through the opening and closing port at the connection between the mixing tank and the fixed plate, and through the flow port inside the connecting pipe into the storage groove of the leak box. The multiple leak holes at the bottom and outer ring of the leak box can make the agent evenly dispersed into the wastewater in the wastewater treatment tank. Attached Figure Description

[0027] refer to Figure 1 , Figures 4 to 5The output shaft of drive motor 1 passes through the inside of cover plate 2 and is fixedly connected to rotating rod 10. Stirring rod 11 rotates inside stirring tank 3. The output shaft of drive motor 17 passes through square plate 4 and is fixedly connected to threaded rod 16.

[0028] Operating principle and advantages: When using this automatic dosing device for wastewater treatment, wastewater is first introduced into the wastewater treatment tank 9 to prepare for subsequent dosing. The chemicals are then added to the mixing tank 3. The cover plate 2 is slidably mounted on the mixing tank 3 via the cooperation of the two side protrusions 12 with the grooves 28 on both sides of the upper end of the mixing tank 3. The slots 14 on the protrusions 12 engage with the locking blocks 13 connected to the springs 15 in the grooves 28 of the mixing tank 3. This spring 15 and locking block 13 structure ensures a tight connection between the cover plate 2 and the mixing tank 3, preventing chemical leakage during mixing. Subsequently, the drive motor 1 is started, and its output shaft passes through the cover plate 2, driving the rotating rod 10 to rotate. The multiple stirring rods 11 on the outer ring of the rotating rod 10 rotate accordingly, thoroughly mixing the chemicals in the mixing tank 3 to ensure uniform chemical concentration and stable dosing effect. After mixing is complete, according to the actual wastewater treatment requirements, the drive motor 17 is started. The output shaft of the drive motor 17 drives the threaded rod... When the threaded rod 16 rotates, the baffle 23 will slide along the limiting plate 20 in the receiving groove 18 inside the fixed plate 5. By controlling the rotation direction and number of turns of the drive motor 17, the position of the baffle 23 at the opening 21 can be precisely adjusted, thereby controlling the flow rate of the agent in the mixing tank 3 into the connecting pipe 6. When the baffle 23 moves to the appropriate position, the agent flows into the storage groove 26 of the leak box 8 through the opening 21 at the connection between the mixing tank 3 and the fixed plate 5, and through the flow port 25 inside the connecting pipe 6. The multiple leak holes 24 opened at the bottom and outer ring of the leak box 8 can make the agent evenly dispersed into the wastewater in the wastewater treatment tank 9. During the entire dosing process, the cylinder 7 can adjust the height position of the mixing tank 3 as needed to facilitate the dosing operation and device maintenance, and can also adapt to the dosing needs of wastewater treatment tanks 9 of different depths.
