Technical Field
[0001] This utility model relates to the technical field of solid corrosion inhibitor production equipment, specifically a material conveying device for solid corrosion inhibitor production. Background Technology
[0002] With the continuous development of the oil and natural gas energy industry, corrosion problems in oil and gas wells are becoming increasingly serious. Corrosion not only affects production efficiency but can also cause serious safety hazards and economic losses. Currently, commonly used corrosion protection measures include two processes: injecting liquid corrosion inhibitors and solid corrosion inhibitors. Solid corrosion inhibitors have gradually become a research hotspot due to their advantages such as ease of transportation, long service life, and environmental friendliness. Solid corrosion inhibitors are diverse, and their preparation processes vary. For example, existing methods use liquid corrosion inhibitors as the main material, employing certain substances with low solubility in water as additives, along with synergists and binders, before granulation or extrusion molding. Because liquid corrosion inhibitors are viscous, heating is usually required during mixing; however, the mixing efficiency still needs improvement. Utility Model Content

In addition, pipe heating jackets are installed on the outside of the feed pipe at the main material inlet and on the outside of the screw conveyor, which can ensure the smooth conveying and pre-mixing of viscous liquid corrosion inhibitors.

The screw conveyor is inclined, and the feed end of the screw conveyor is lower than the discharge end. The feed end of the screw conveyor is provided with a main material feed inlet 1 and an auxiliary material feed inlet 2 in sequence along the conveying direction. The upper part of the main material feed inlet 1 is connected to a feed pipe 3. A first pipe heating jacket 4 is provided on the outside of the feed pipe 3. A second pipe heating jacket 5 is provided on the outside of the screw conveyor. The discharge end of the screw conveyor is provided with a discharge outlet 6. The mixing mechanism is provided below the discharge outlet 6.
[0017] Specifically, the screw conveyor includes a cylindrical conveying pipe 7, a reduction motor 8, a rotating shaft, and helical blades. The rotating shaft is rotatably arranged inside the cylindrical conveying pipe 7, and the helical blades are arranged outside the rotating shaft. One end of the rotating shaft passes through the cylindrical conveying pipe 7 and is provided with a first pulley at the end. The output shaft of the reduction motor 8 is provided with a second pulley, and the two pulleys are connected by a belt for transmission. Two tripods 9 of different heights are provided at the bottom of the cylindrical conveying pipe 7.
