Description

Technical Field

[0001] This utility model relates to the field of dosing machine technology, and in particular to a mixing and uniform dosing machine for water treatment. Background Technology

[0002] Chemical dosing in wastewater treatment refers to the process of removing pollutants through chemical reactions or physical actions by adding chemical agents (such as coagulants, flocculants, coagulant aids, and disinfectants) to wastewater. For example, coagulants (such as polyaluminum chloride) neutralize the charge of suspended particles, causing them to aggregate; flocculants (such as polyacrylamide) promote the formation of larger particles from small flocs, facilitating sedimentation; and disinfectants (such as sodium hypochlorite) kill pathogenic microorganisms. Ultimately, water purification is achieved through processes such as sedimentation and filtration. Chemical dosing is commonly used in pretreatment, advanced treatment, or sludge conditioning stages and is a key means of improving treatment efficiency.

[0003] Currently, chemical dosing machines are needed as an auxiliary operation in the process of adding chemicals for wastewater treatment.

[0004] Existing dosing machines typically install the mixing tank at the top of the sewage tank. Workers need to pour the chemicals and water into the mixing tank from a height to mix them, and then use a dosing pump and spray pipes to evenly spray the solution onto the sewage surface. A moving mechanism is used to adjust the spray position to improve the coverage. However, because the mixing tank is installed at a high position, manual dosing of chemicals and water requires climbing or the use of tools, which is inconvenient and poses safety hazards.

[0005] Therefore, improvements are proposed. Utility Model Content

[0021] The top of the medicine container 11 is sealed with a cover plate 10.

[0022] A metering feeding assembly is fixedly connected to the bottom of the reagent tank 11. The metering feeding assembly includes a feeding pipe 20, which is fixedly installed at the bottom of the reagent tank 11. A servo motor 19 is fixedly installed on one side of the outer surface of the feeding pipe 20. The drive shaft of the servo motor 19 passes through the interior of the feeding pipe 20 and is fixedly connected to a roller 21. Both sides of the outer surface of the roller 21 are sealed and fitted to the inner wall of the feeding pipe 20. Multiple material grooves 22 are evenly opened in the middle area of ​​the outer surface of the roller 21. Both sides of the outer surface of the roller 21 are fixedly fitted with sealing rings. The sealing rings are sealed and abut against the inner wall of the feeding pipe 20 to prevent reagent leakage and ensure that the dosage is stable and adjustable.

[0023] The fixed column 13 is equipped with water supply pipe fittings, including a fixed pipe 9. The fixed pipe 9 and the fixed column 13 are connected by multiple connecting blocks 14. The outlet of the fixed pipe 9 is fixedly connected to a solenoid valve 12. The inlet of the fixed pipe 9 is fixedly connected to the municipal tap water pipe, which can provide tap water source.

[0024] Two sets of rails 6 are fixedly installed on the top of the support plate 7. The two sets of rails 6 are used to install a mobile platform. A mixing tank 4 is fixedly installed on one side of the top of the mobile platform. The mobile platform includes two electric railcars 5, and the electric railcars 5 are mounted on an adjacent set of rails 6. The tops of the two electric railcars 5 are fixedly connected to a cross seat 3, and the mixing tank 4 is fixedly installed on the top of the cross seat 3. The electric railcar 5 is also known as an electric flatcar, rail flatcar, electric flatbed car, rail flatcar, electric car, trolley, crosscar, ground car, etc., and is a kind of in-plant rail electric transport vehicle.

[0025] A liquid level sensor 15 is fixedly installed on one side of the top of the mixing tank 4. The liquid level sensor 15 is a radar liquid level sensor, model NHSW47, used to detect the water level and determine the amount of tap water to be added.

[0026] A chemical spraying assembly is installed between the mixing tank 4 and the mobile platform.

[0027] Working principle: The reagent tank 11 is raised and lowered along the fixed column 13 via an electric lifting assembly (stepper motor 17 drives screw 23, which in turn moves slide 18 up and down). When adding reagents, the reagent tank 11 is lowered to the low position, making it convenient for workers or machinery to replenish solid or liquid reagents. After adding reagents, the reagent tank 11 is raised to the high position, and then the electric railcar 5 moves along the track 6, moving the mixing tank 4 below the solenoid valve 12 and the discharge pipe 20 via the cross seat 3. The solenoid valve 12 opens, and tap water is delivered into the mixing tank 4 through the fixed pipe 9. The liquid level sensor 15 monitors the liquid level. When the liquid level reaches the threshold, the solenoid valve 12 closes, and the servo motor 19 drives the roller shaft 21 to rotate, controlling the amount of material discharged each time through the volume of the material trough 22 until the required amount is reached. The mixing tank 4 mixes water and chemicals. The mixed solution is then pumped by the water pump 16 and transported through the horizontal pipe 2 to multiple nozzles. The solution is then sprayed onto the sewage. The electric railcar 5 moves back and forth along the track 6, causing the spraying components to evenly distribute the solution above the sewage tank, avoiding local over-concentration or over-dilute conditions and improving the sewage treatment effect.

[0028] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the solenoid valve 12, servo motor 19, stepper motor 17, stirring tank 4, and level sensor 15 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that this hardware structure improvement can achieve in combination with common knowledge.
