Detailed Implementation

[0018] 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.

[0019] Please see Figure 1-5 This utility model provides a technical solution: a dosing device for sewage treatment, including a dosing tank body 4 and a base 5. A first motor 12 is arranged on the upper wall of the dosing tank body 4, and a stirring paddle 10 is arranged on the driving end of the first motor 12. The stirring paddle 10 is rotatably disposed inside the dosing tank body 4. A replenishment chamber 22 is arranged on the upper wall of the dosing tank body 4 and on one side of the first motor 12. A drive chamber 19 is arranged inside the replenishment chamber 22. The device is equipped with a second motor 21, and a stop block 23 is provided on the drive end of the second motor 21. The replenishment chamber 22 is equipped with a metering tank 18. The stop block 23 is movably mounted on the metering tank 18. The stop block 23 is equipped with a drug inlet 26 and a drug outlet 27. The replenishment chamber 22 is equipped with a drug storage tank 1. The drug storage tank 1 is equipped with a sloping guide block 24. The replenishment chamber 22 is equipped with a drug addition channel 20. The drug addition tank body 4 is equipped with a pair of patch level gauges 28.

[0020] The first motor 12 is driven to rotate, which in turn drives the agitator 10 to rotate. This agitates the water and chemicals in the dosing tank 4, making the water and chemicals mix evenly and thus improving the dissolution effect of the chemicals.

[0021] Medicine storage tank 1 is used to store medicines;

[0022] When filling the metering tank 18 with medicine, the second motor 21 is driven to rotate, which drives the stop block 23 to rotate, so that the medicine inlet 26 moves to the top of the metering tank 18. The medicine in the storage tank 1 enters the metering tank 18 through the medicine inlet 26. At this time, the bottom of the metering tank 18 is blocked by the stop block 23, which can prevent the medicine in the metering tank 18 from flowing out.

[0023] When adding medicine into the dosing tank body 4, the second motor 21 is driven to rotate, which drives the stop block 23 to rotate, so that the inlet 26 is away from the top of the metering tank 18, preventing the medicine in the storage tank 1 from entering the metering tank 18. At the same time, the outlet 27 is moved to the bottom of the metering tank 18, and the medicine in the metering tank 18 enters the dosing tank body 4 through the outlet 27 and the dosing channel 20.

[0024] The patch level gauge 28 is used to detect the liquid level inside the dosing tank body 4. One patch level gauge 28 is installed at the low liquid level of the dosing tank body 4, and the other patch level gauge 28 is installed at the high liquid level of the dosing tank body 4. The amount of water replenished inside the dosing tank body 4 can be controlled by adjusting the position of the patch level gauge 28, thereby adjusting the concentration of the agent inside the dosing tank body 4.

[0025] In this embodiment, the dosing tank body 4 is further configured to have a support frame 7, a filter 13 on the support frame 7, a drain outlet 15 and a drain pipe 17 on the filter 13, a filter screen 16 inside the filter 13, and a second solenoid valve 14 on the drain pipe 17 and located on one side of the filter 13.

[0026] The sewage pipe 17 can discharge the sewage in the dosing tank body 4 to a designated location, and the second solenoid valve 14 is used to control the opening and closing of the sewage pipe 17;

[0027] A drain cover is screwed onto the drain outlet 15. When sewage passes through the filter 13, the filter screen 16 is used to block floating objects in the sewage and allow the floating objects in the water to enter the drain outlet 15. Opening the drain cover on the drain outlet 15 makes it easier for staff to clean the floating objects and prevent the filter 13 from being blocked by the floating objects in the water.

[0028] In this embodiment, the base 5 is further configured to have a support frame 7, the support frame 7 is configured to have a metering pump 8, the metering pump 8 is configured to have a first dosing pipe 6 and a second dosing pipe 9, and the first dosing pipe 6 is connected to the dosing tank body 4.

[0029] One end of the second dosing pipe 9 is connected to the dosing point of the sewage treatment equipment, which drives the metering pump 8 to start, so that the chemicals in the dosing tank body 4 can be used to treat the sewage through the first dosing pipe 6 and the second dosing pipe 9.

[0030] In this embodiment, the base 5 is provided with a grid plate 25, and the dosing tank body 4 is disposed on the grid plate 25.

[0031] In this embodiment, the dosing tank body 4 is further configured to have a water supply pipe 3, and the water supply pipe 3 is configured to have a first solenoid valve 2.

[0032] The first solenoid valve 2 is used to control the opening and closing of the water supply pipe 3.

[0033] In this embodiment, an observation port 11 is provided on the dosing tank body 4 and on the other side of the first motor 12;

[0034] The observation port 11 allows staff to easily observe the contents of the dosing tank 4.

[0035] Example: When adding medicine to the storage tank 1, the second motor 21 is driven to rotate, causing the stop block 23 to rotate, moving the inlet 26 away from the top of the metering tank 18. When medicine is added to the storage tank 1 and the metering tank 18 is being filled, the second motor 21 is driven to rotate, causing the stop block 23 to rotate, moving the inlet 26 above the metering tank 18. The medicine in the storage tank 1 enters the metering tank 18 through the inlet 26. At this time, the bottom of the metering tank 18 is blocked by the stop block 23, preventing the medicine in the metering tank 18 from flowing out. When the liquid level gauge 28 detects that the liquid level in the dosing tank body 4 is low, it drives the first solenoid valve 2 to open, replenishing water in the dosing tank body 4. This drives the second motor 21 to rotate, causing the stop block 23 to rotate, moving the inlet 26 away from the top of the metering tank 18 to prevent the chemicals in the storage tank 1 from entering the metering tank 18. Simultaneously, it moves the outlet 27 to the bottom of the metering tank 18, allowing the chemicals in the metering tank 18 to enter the dosing tank body 4 through the outlet 27 and the dosing channel 20. This allows for the use of chemicals within the dosing tank body 4. After completion, the system automatically adds an appropriate amount of reagent to the dosing tank, avoiding waste of manpower. It drives the first motor 12 to rotate, which in turn drives the agitator 10 to rotate, stirring the water and reagent inside the dosing tank 4 to ensure uniform mixing and improve reagent dissolution. When the patch-type level gauge 28 detects a high liquid level inside the dosing tank 4, it drives the first solenoid valve 2 to close, stopping water replenishment to the dosing tank 4. When adding reagents to the wastewater treatment equipment, it drives the metering pump 8 to start, ensuring the reagent is added to the dosing tank 4. The chemicals are added to treat the wastewater through the first dosing pipe 6 and the second dosing pipe 9. When the dosing tank body 4 is discharged, the first solenoid valve 2 is activated to open the sewage discharge pipe 17. The sewage discharge pipe 17 can discharge the wastewater in the dosing tank body 4 to a designated location. When the wastewater passes through the filter 13, the filter screen 16 is used to block floating objects in the wastewater and allow the floating objects in the water to enter the sewage discharge port 15. Opening the sewage discharge port 15 can facilitate the staff to clean the floating objects and prevent the floating objects in the water from clogging the filter 13.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
