Description

Technical Field

[0001] This utility model relates to the technical field of viscosity monitoring devices, and in particular to an online viscosity monitoring device for ultra-high wear-resistant self-emulsifying polyethylene wax emulsion. Background Technology

[0002] Polyethylene wax emulsions are widely used in water-based coatings, inks, textile auxiliaries, and leather finishing agents due to their excellent lubricity, abrasion resistance, dispersibility, and film-forming properties. During production, emulsion viscosity is a key process parameter affecting product stability, coating performance, and shelf life; therefore, real-time monitoring using online viscosity monitoring devices has become standard practice in modern production lines.

[0003] For example, CN219400116U discloses an online viscosity detection reactor for emulsion polymerization with an ultrasonic generator, which relates to the field of viscosity detection. The reactor includes a stirring shaft connected to a motor and a reducer. A viscometer probe is installed inside the reactor and connected to a telescopic rod. The telescopic rod passes through the top of the reactor and is externally connected to a viscometer detector, allowing real-time monitoring of viscosity changes during emulsion polymerization without the need for separate removal for testing, thus improving efficiency. The stirring shaft has multiple locking slots spaced axially, with stirring paddles fitted onto these slots. The number of stirring paddles corresponds to the number of locking slots below the emulsion surface, ensuring the stirring paddles do not spin dry. Multiple ultrasonic generators are mounted around the sidewall of the reactor via flanges. These ultrasonic generators are connected to ultrasonic vibrating rods that penetrate the sidewall of the reactor, vibrating to remove air bubbles generated during stirring of the emulsion by the stirring shaft, resulting in more accurate viscosity changes. However, because this online viscosity detection reactor with ultrasonic generators requires manual opening of the reactor lid for cleaning after the emulsion is discharged, the operation is cumbersome, time-consuming, and labor-intensive, severely impacting production efficiency.

[0004] Therefore, an online viscosity monitoring device for ultra-high wear-resistant self-emulsifying polyethylene wax emulsion has been developed, which can automatically clean the inside of the detection cylinder, save manpower, and improve emulsion production efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing online viscosity monitoring reactors for emulsion polymerization equipped with ultrasonic generators, which require manual opening of the reactor lid for cleaning after emulsion discharge, resulting in cumbersome, time-consuming, and labor-intensive operations that severely impact production efficiency, this invention provides an online viscosity monitoring device for ultra-high wear-resistant self-emulsifying polyethylene wax emulsion that can automatically clean the inside of the detection cylinder, saving manpower and improving emulsion production efficiency.

[0006] An online viscosity monitoring device for ultra-high wear-resistant self-emulsifying polyethylene wax emulsion includes a production tank, a mounting cover, a detection cylinder, positioning blocks, a feed pipe, a control valve, a water inlet pipe, a motor, a rotating shaft, a viscometer, a limiting component, and a scraping component. The production tank has a mounting cover connected to its upper right side, and a detection cylinder is located below the mounting cover. Positioning blocks are connected to the upper sides of both the front and rear of the detection cylinder, and these positioning blocks engage with the mounting cover. A feed pipe connects the production tank and the mounting cover, and a control valve is connected to the feed pipe and to the production tank. A water inlet pipe is connected to the upper right side of the detection cylinder. A motor is connected to the upper middle part of the mounting cover, and a rotating shaft is connected to the motor's output shaft. The rotating shaft is rotatably connected to the mounting cover, and a viscometer is connected to the lower side of the rotating shaft. A limiting component is provided on the mounting cover to restrict the detection cylinder, and a scraping component is provided between the rotating shaft and the detection cylinder to scrape away residual emulsion.

[0007] To further clarify, a valve is installed on the lower side of the detection cylinder.

[0008] To further explain, the limiting component includes guide rods, a limiting frame, and elastic elements. Two guide rods are connected to the upper middle part of the mounting cover. The motor is located below the guide rods. The limiting frame is slidably connected between the guide rods. The limiting frame is engaged with the positioning block. Elastic elements are connected between the limiting frame and the guide rods.

[0009] To further explain, a handle is provided on the upper side of the restraint frame.

[0010] To further clarify, the elastic element is a telescopic spring.

[0011] To further explain, the scraping assembly includes an electric push rod, a sliding frame, and a scraping frame. The electric push rod is connected to the inner side of the upper part of the rotating shaft, and the sliding frame is connected to the telescopic end of the electric push rod. The sliding frame is slidably connected to the rotating shaft, and the scraping frame is rotatably connected inside the detection cylinder. The sliding frame and the scraping frame are engaged.

[0012] To further explain, the control valve, motor, viscosity meter, electric actuator, and processor are electrically connected through the control module.

[0013] The beneficial effects of this utility model are as follows: This utility model introduces water into the detection cylinder through the water inlet pipe, and at the same time activates the electric push rod to push the sliding frame to move downward and engage with the scraping frame. This causes the rotating shaft to rotate, which in turn drives the scraping frame to rotate, thereby scraping the emulsion in the detection cylinder. This achieves the effect of automatically cleaning the inside of the detection cylinder, saving manpower and improving the efficiency of emulsion production. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0021] An online viscosity monitoring device for ultra-high wear-resistant self-emulsifying polyethylene wax emulsion, such as... Figures 1-5 As shown, the system includes a production tank 1, a mounting cover 2, a detection cylinder 3, a positioning block 31, a feed pipe 4, a control valve 5, a water inlet pipe 6, a motor 10, a rotating shaft 11, a viscosity meter 12, a limiting component, and a scraping component. The upper right side of the production tank 1 is connected to the mounting cover 2, and the lower side of the mounting cover 2 is equipped with the detection cylinder 3. The lower side of the detection cylinder 3 is equipped with a valve for easy material discharge. The upper sides of both the front and rear parts of the detection cylinder 3 are connected to the positioning blocks 31, which are engaged with the mounting cover 2. The feed pipe 4 connects the production tank 1 and the mounting cover 2, and the feed pipe 4 is equipped with the control valve 5, which is connected to the production tank 1. The upper right side of the detection cylinder 3 is connected to the water inlet pipe 6. The upper middle part of the mounting cover 2 is connected to the motor 10, and the output shaft of the motor 10 is connected to the rotating shaft 11, which is rotatably connected to the mounting cover 2. The lower side of the rotating shaft 11 is connected to the viscosity meter 12. The mounting cover 2 is equipped with a limiting component, and the rotating shaft 11 and the detection cylinder 3 are equipped with a scraping component.

[0022] like Figures 1-4 As shown, the limiting component includes guide rods 7, limiting frame 8, and elastic element. Two guide rods 7 are connected to the upper middle part of the mounting cover 2. The motor 10 is located below the guide rods 7. The limiting frame 8 is slidably connected between the guide rods 7. The limiting frame 8 is provided with a handle on the upper side for easy pulling. The limiting frame 8 is engaged with the positioning block 31. Elastic element is connected between the limiting frame 8 and the guide rods 7. The elastic element is a telescopic spring 9.

[0023] like Figure 2 , Figure 3 and Figure 5 As shown, the scraping assembly includes an electric push rod 13, a sliding frame 14, and a scraping frame 15. The electric push rod 13 is connected to the inner side of the upper part of the rotating shaft 11. The sliding frame 14 is connected to the telescopic end of the electric push rod 13. The sliding frame 14 is slidably connected to the rotating shaft 11. The scraping frame 15 is rotatably connected inside the detection cylinder 3. The sliding frame 14 and the scraping frame 15 are engaged. The control valve 5, motor 10, viscosity meter 12, electric push rod 13, and processor are electrically connected through a control module.

[0024] When using this utility model, first place the production tank 1 in the production area of ​​ultra-high wear-resistant self-emulsifying polyethylene wax emulsion, then pull the limiting frame 8 upward, the telescopic spring 9 is squeezed and contracted, and then the detection cylinder 3 is snapped onto the mounting cover 2 by the positioning block 31. Then release the limiting frame 8, the telescopic spring 9 rebounds, so that the limiting frame 8 moves downward and resets to engage with the positioning block 31, limiting the positioning block 31. After the ultra-high wear-resistant self-emulsifying polyethylene wax emulsion is produced, open the control valve 5 so that the emulsion enters the detection cylinder 3 from the feed pipe 4. The processor starts the motor 10 through the control module, drives the rotating shaft 11 and the viscosity meter 12 to rotate, stirs the emulsion, and monitors the viscosity of the emulsion through the viscosity meter 12. When the viscosity of the emulsion is qualified, open the valve on the lower side of the detection cylinder 3 to discharge the emulsion. When the next batch of emulsion needs to be produced, water is introduced into the detection cylinder 3 through the water inlet pipe 6. At the same time, the electric push rod 13 is activated, pushing the sliding frame 14 to move downward and engage with the scraping frame 15. This causes the rotating shaft 11 to rotate, which in turn drives the scraping frame 15 to rotate, thereby scraping the emulsion in the detection cylinder 3. The waste liquid is discharged from the bottom of the detection cylinder 3, thus automatically cleaning the inside of the detection cylinder 3, saving manpower and improving the efficiency of emulsion production.
