[0033] A device for adding solid reagents to offshore oil and gas wells, such as Figure 1 As shown, it includes a conveying pipe 401, a hopper structure, a feeding barrel 502, a driving mechanism and a vibration mechanism; flange plates 402 are provided at the left and right ends of the conveying pipe 401, and a connecting pipe 403 is provided in the middle of the conveying pipe 401; the bottom of the feeding barrel 502 is rotatably connected to the connecting pipe 403, and the top of the feeding barrel 502 is rotatably connected to the hopper structure. The driving mechanism is used to realize the rotation of the feeding barrel 502, and a spiral conveying mechanism is provided inside the feeding barrel 502; Figure 4 As shown, the screw conveyor mechanism includes multiple screw conveyor blades 503, which are evenly arranged around the inner wall of the feed barrel 502. The screw conveyor mechanism enables continuous and uniform delivery of solid pharmaceuticals, ensuring a stable flow of pharmaceuticals from the hopper to the target location, avoiding sudden changes in the amount of pharmaceuticals delivered. The screw conveyor blades 503 maintain the movement of the material in the conveying pipe 401, reducing the risk of blockage caused by stagnation or accumulation. Compared to other conveying mechanisms, the screw conveyor mechanism is more compact and suitable for use on offshore platforms with limited space.
[0034] like Figure 2 As shown, the hopper structure includes a cylindrical portion 101 and a conical barrel portion 102. The cylindrical portion 101 is integrally connected to the upper end surface of the conical barrel portion 102. The inner wall of the cylindrical portion 101 is provided with a first guide structure, and the inner wall of the conical barrel portion 102 is provided with a second guide structure. The output end of the vibration mechanism is arranged on the inner side of the cylindrical portion 101. The cylindrical portion 101 and the conical barrel portion 102 of the hopper enable the solid medicine to flow smoothly from top to bottom, reducing the accumulation and stagnation of the material inside. A first guide structure (guide plate 202) and a second guide structure (spiral guide groove 103) are provided inside to help guide the medicine to flow evenly downward and prevent deviation or blockage. The conical design combined with the internal guide structure helps prevent the solid medicine from forming a bridge in the hopper, thereby avoiding the phenomenon of the material getting stuck and not sliding down.

The second guide structure includes a plurality of spiral guide grooves 103, which are evenly arranged around the inner wall of the conical portion 102. The outer surface of the cylindrical portion 101 is provided with a plurality of screw protrusions 201, which are arranged around the outer wall of the cylindrical portion 101.

The output end of the vibrating motor 302 is connected to the vibrating rod 301, and the mounting bracket 303 is mounted on the fixed end of the vibrating motor 302. Through vibration, the vibration mechanism effectively prevents the solid medication from clumping and accumulating within the hopper and conveying pipe 401, maintaining good fluidity of the medication. Vibration helps loosen any potentially clumping materials, reducing the risk of blockage and ensuring the continued stable operation of the dosing device. Vibration promotes uniform dispensing of the medication, ensuring a smooth conveying process and improving the efficiency of the entire system.
[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
