Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a composite carbon source dosing device for wastewater treatment. Background Technology

[0002] In wastewater treatment, processes such as microbial denitrification often require the supplementation of carbon sources to ensure the normal metabolic activities of microorganisms and achieve efficient pollutant removal. Traditional carbon sources, such as glucose, have some limitations, such as being easily utilized by microorganisms, making it difficult to accurately control the carbon source dosage, and having certain requirements for transportation and storage. Composite carbon sources, on the other hand, combine multiple organic components and can provide the necessary carbon elements for microorganisms more stably and continuously.

[0003] However, in practical applications, manually adding composite carbon sources is not only labor-intensive and inefficient, but also makes it difficult to ensure the accuracy and timeliness of dosing. This can easily lead to problems such as excessive dosage causing waste and increased treatment costs, or insufficient dosage affecting wastewater treatment results. Therefore, there is an urgent need for a precise, stable, and automated composite carbon source dosing device for wastewater treatment to standardize the dosing process and improve the overall quality and efficiency of wastewater treatment.

[0007] Furthermore, the dosing assembly includes a collection chamber, a delivery pipe, a slider, and an adjusting rod. The collection chamber is fixed to the lower end of the tank and communicates with the tank. The delivery pipe is fixed to one end of the collection chamber and communicates with the collection chamber. The slider is slidably disposed inside the delivery pipe. The adjusting rod is threadedly connected to one end of the delivery pipe. The lower end of the delivery pipe is provided with a liquid outlet. The upper end of the slider is provided with a through hole communicating with the liquid outlet. One end of the adjusting rod is provided with a pressing plate. A spring is provided between the pressing plate and the slider. The other end of the pressing plate is provided with a pressure sensor.

[0008] Furthermore, a microprocessor is provided between the bases, the rotary motor is electrically connected to the microprocessor via wires, and a density sensor is provided inside the tank, which is connected to the microprocessor via wires.

[0009] Furthermore, one end of the liquid inlet is connected to a solenoid valve, and the solenoid valve is electrically connected to the microprocessor via a wire.

[0010] Furthermore, a water pump is installed inside the collection chamber. The inlet of the water pump is connected to the collection chamber, and the outlet of the water pump is connected to the delivery pipe. The water pump is electrically connected to the microprocessor via a wire.

[0011] Furthermore, the spring is disposed inside the delivery tube, with one end of the spring in contact with the slider and the other end of the spring in contact with the pressure sensor, which is electrically connected to the microprocessor via a wire.

[0024] like Figure 1 As shown, a composite carbon source dosing device for wastewater treatment includes a base 1 and a tank 2.

It also includes a dosing component disposed on one side of the tank 2 to precisely control the dosing amount. An inlet 3 is provided on one side of the tank 2.

[0025] like Figure 2-3 As shown in -4-6, the mixing assembly includes a baffle 4, a power roller 5, and an agitator 6. The upper end of the tank body 2 has a feed inlet, the baffle 4 is fixed to the upper end of the feed inlet, the bottom of the inside of the baffle 4 is provided with a filter plate 7, the side of the baffle 4 has a slag discharge port 8, the power roller 5 is installed through the inside of the tank body 2, the extended end of the power roller 5 is poweredly connected to the power end of the rotary motor 9, the rotary motor 9 is fixed to the outside of the tank body 2, and the agitator 6 is fixed to the side of the power roller 5.

[0026] The tank 2 is equipped with a microprocessor located between the bases 1 and a rotary motor 9 electrically connected to the microprocessor via wires. A density sensor is located inside the tank 2 and is connected to the microprocessor via wires. One end of the inlet 3 is connected to a solenoid valve, which is also electrically connected to the microprocessor via wires. The tank 2 is a horizontal cylindrical design, capable of withstanding a certain internal pressure and facilitating the installation of various auxiliary equipment. Both ends of the tank 2 are elliptical end caps to effectively distribute pressure and ensure the overall strength of the tank 2. The upper end of the enclosure 4 is equipped with a sealing cap that is tightly connected to it. Raw materials pass through the enclosure... 4. The raw material enters the tank 2. The filter plate 7 filters the raw material, isolating large particles on the filter plate 7. The large particles are then removed through the slag discharge port 8 on one side of the enclosure 4. The density sensor monitors the density inside the tank 2. The microprocessor controls the solenoid valve and the rotary motor 9. The solenoid valve controls the liquid inlet flow, and the power end of the rotary motor 9 drives the power roller 5 to rotate. The stirrer 6 agitates the raw material and the mixture, keeping the liquid composite carbon source in the tank in a uniform state at all times. This avoids the formation of layers or sedimentation due to prolonged standing, which would affect the quality and performance of the carbon source.

[0027] like Figure 2-3 As shown in Figure 4-5, the dosing assembly includes a collection chamber 10, a delivery pipe 11, a slider 12, and an adjusting rod 13. The collection chamber 10 is fixed to the lower end of the tank body 2 and is connected to the tank body 2.

The adjusting rod 13 is threadedly connected to one end of the delivery pipe 11. The lower end of the delivery pipe 11 is provided with an outlet 14. The upper end of the slider 12 is provided with a through hole 15 connected to the outlet 14. One end of the adjusting rod 13 is provided with a pressing plate 16. A spring 17 is provided between the pressing plate 16 and the slider 12. The other end of the pressing plate 16 is provided with a pressure sensor.

[0028] The collection chamber 10 is equipped with a water pump 18.

One end of the spring 17 is in contact with the slider 12, and the other end of the spring 17 is in contact with the pressure sensor. The pressure sensor is electrically connected to the microprocessor via a wire. The microprocessor controls the water pump 18 to draw the mixture in the collection chamber 10 into the delivery pipe 11, pushing the slider 12 to move and generating pressure on the spring 17, causing the spring 17 to undergo elastic deformation. The through hole 15 is connected to the liquid outlet 14, and the mixture is discharged from the liquid outlet 14. The hydraulic pressure is controlled by adjusting the adjusting rod 13, and the discharge flow rate is precisely controlled according to the requirements. The flow metering device accurately counts the discharge amount, providing data support for subsequent production and use. The pressure sensor monitors the pressure inside the tank. When the pressure exceeds the safe range, the corresponding pressure relief measures are automatically activated to ensure the safety of the tank 2.
