Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a demulsifier addition device. Background Technology
[0002] In the field of wastewater treatment, especially when treating oily wastewater, the addition of demulsifiers is a key step in achieving effective oil-water separation and water purification. With the acceleration of industrialization, the discharge of oily wastewater continues to increase and its composition becomes more complex, which puts forward higher requirements for the efficiency and quality of wastewater treatment.
[0003] Currently, due to the wide range of wastewater sources and the complex and varied composition, the content, types, and emulsification degree of oily substances in different industrial wastewater, domestic sewage, and mixed sewage vary greatly. Traditional demulsifier addition still largely relies on manual operation. Manual operation not only consumes a lot of manpower, but also makes it difficult to ensure the consistency and stability of the amount of demulsifier added due to factors such as the skill level and fatigue level of the operators. Often, excessive addition leads to chemical residues, affecting the activity of microorganisms in subsequent biological treatment processes and increasing treatment costs; or insufficient addition prevents the emulsified oil from being fully broken down, resulting in substandard effluent quality and failure to pass environmental monitoring.

[0020] Example 1
[0021] like Figures 1 to 4 As shown, this utility model discloses a demulsifier addition device. The technical solution adopted is as follows: it includes a base 1, a control module 2 is fixedly installed on one side of the top of the base 1, a storage tank 3 is fixedly installed on the top of one end of the base 1, an addition mechanism 4 connected to the storage tank 3 is installed on the top of the other end of the base 1, and an inverted U-shaped fixing seat 5 is fixedly installed on the top of the base 1.
[0022] The feeding mechanism 4 includes a discharge pipe 41, a solenoid valve 42, a measuring barrel 43, a check valve 44, a feed pipe 45, and a feed pump 46. The measuring barrel 43 is fixedly installed on the top of the other end of the base 1. Both ends of the feed pipe 45 are connected to the discharge port on the lower side of the storage barrel 3 and the feed port on the lower side of the measuring barrel 43. The feed pump 46 is installed on the feed pipe 45 and is fixedly installed on the side of the storage barrel 3. The check valve 44 is installed on the feed pipe 45. The discharge port on the lower side of the measuring barrel 43 is connected to one end of the discharge pipe 41. A long strip-shaped observation window 10 is provided on the side of the measuring barrel 43, and a scale 11 is provided on one side of the observation window 10. Through the observation window 10 and the scale 11, the operator can easily and accurately determine the adjustment position of the piston plate 61. For ease of use, a solenoid valve 42 is installed on the discharge pipe 41. An adjustable metering mechanism 6 is installed inside the measuring barrel 43. The adjustable metering mechanism 6 includes a piston plate 61, a lead screw 62, a guide rod 63, a drive gear 64, a transmission gear 65, a lifting plate 66, and electric push rods 67. There are two electric push rods 67. The upper ends of the two electric push rods 67 are fixedly connected to the top of the fixed base 5, and the other ends of the two electric push rods 67 are fixedly connected to both sides of the top of the lifting plate 66. A transmission gear 65 is rotatably installed in the middle of the top of the lifting plate 66, and a drive gear 64 is rotatably installed on one side of the top of the lifting plate 66. The drive gear 64 meshes with the transmission gear 65. A push rod 7 is fixedly installed on one side of the top of the drive gear 64. The piston plate 61 is slidably installed on the measuring... Inside the measuring barrel 43, a waterproof and breathable valve 8 is fixedly installed on the top of the piston plate 61. The waterproof and breathable valve 8 connects to the inside of the measuring barrel 43, and can balance the air pressure inside the measuring barrel 43, preventing the amount of demulsifier in the measuring barrel 43 from being less than the scale value due to air pressure imbalance. A rubber ring 9 is fixedly installed in the annular groove on the side of the piston plate 61. The side of the rubber ring 9 contacts the inner wall of the measuring barrel 43, and the rubber ring 9 can make tight contact with the inner wall of the measuring barrel 43, effectively preventing the leakage of demulsifier. The middle of the top of the piston plate 61 is fixedly connected to one end of the lead screw 62, and the other end of the lead screw 62 passes through the thread hole in the middle of the bottom of the transmission gear 65. The two sides of the top of the piston plate 61 are respectively fixedly connected to one end of two guide rods 63. The upper end of 63 passes through two sliding holes on both sides of the bottom of the lifting plate 66. The solenoid valve 42 and the feed pump 46 are electrically connected to the control module 2. The feed pump 46 can transport the demulsifier in the storage tank 3 to the measuring tank 43. By controlling the opening and closing of the solenoid valve 41, the demulsifier can be automatically added. The whole process does not require frequent manual intervention, which greatly reduces labor costs. At the same time, it improves the stability and consistency of the addition process, reduces errors caused by human factors, and ensures the accuracy and stability of demulsifier addition. Through the meshing structure of the drive gear 64 and the transmission gear 65, and the connection between the lead screw 62 and the piston plate 61, the operator can precisely adjust the lifting height of the piston plate 61 by rotating the push rod 7 on the top of the drive gear 64.This allows for precise control of the amount of demulsifier added to the measuring tank 43, achieving accurate control over the amount of demulsifier added and avoiding resource waste or poor demulsification effect caused by improper addition.
[0023] The working principle of this utility model is as follows: When an external power source is connected, demulsifier is added to the storage tank 3. The amount of demulsifier added is determined based on the amount of wastewater. Pushing the push rod 7 causes the drive gear 64 to rotate, which in turn drives the transmission gear 65. The threaded hole on the transmission gear 65 causes the lead screw 62 to move up and down, which in turn moves the piston plate 61 up and down. The piston plate 61 is adjusted to a suitable position via the observation window 10 and the scale 11, ensuring that the volume of the measuring tank 43 below the piston plate 61 matches the amount of demulsifier added. The control module 2 controls the feed pump 46 to operate, allowing the demulsifier in the storage tank 3 to be transported to the measuring tank 43 through the feed pipe 45. Inside, as the amount of demulsifier in the measuring tank 43 increases, the air inside the measuring tank 43 will be discharged to the outside through the waterproof and breathable valve 8, thereby ensuring the air pressure balance inside the measuring tank 43. This allows the demulsifier to fill the space below the piston plate 61 inside the measuring tank 43. At this time, the amount of demulsifier in the measuring tank 61 is consistent with the amount of demulsifier to be added. The control module 2 controls the solenoid valve 42 to open and controls the electric push rod 67 to extend, causing the electric push rod 67 to drive the lifting plate 66 and the piston plate 61 to move downward. This allows the demulsifier in the measuring tank 43 to be quickly discharged through the discharge pipe 41 and added to the sewage, thereby ensuring the accuracy of the amount of demulsifier added, avoiding adding too much or too little, and ensuring the stability of sewage treatment.
