Description

Technical Field

[0001] This utility model relates to the field of ternary injection technology in oil fields, and in particular to a delivery device. Background Technology

[0002] Chemical flooding has become one of the important means of stabilizing production in the tertiary recovery stage of oilfields. The polymer dispersion unit is a device that prepares the chemical agents used for oil displacement into a standard solution. The polymer dispersion unit is equipped with an external pump at the outlet of the dispersion tank to transport the prepared polymer mother liquor. During the polymer preparation process, some polymer particles inevitably fail to mature. Unmatured polymer particles are colloidal and commonly known as "fish eyes". Fish eyes no longer participate in the maturation process. Therefore, when the polymer mother liquor is transported into the external pump after preparation, the mixed polymer mother liquor enters the external pump. The individual fish eyes tend to aggregate in the impeller of the external pump and merge into large colloids, thus clogging the impeller. Utility Model Content

[0003] To address the problem of unripe particles clogging the external pump after polymer mother liquor preparation, this invention provides a conveying device.

[0004] The technical solution provided by this utility model is: a conveying device, including an installation pipe and a reducer. Flanges are welded on both sides of the installation pipe. An inwardly extending installation ring is provided in the inner hole of the installation pipe. The installation ring is connected to a tool holder by bolts. The tool holder is disc-shaped. A bushing is provided on the right side of the tool holder. A through hole is machined in the bushing. The reducer is connected to the bushing by bolts. The reducer is a coaxial reduction mechanism. The high-speed shaft of the reducer passes through the through hole of the bushing to the left and connects to the moving tool. The low-speed shaft of the reducer is connected to a spiral impeller by a flat key and a retaining ring. The retaining ring provides axial limit for the spiral impeller.

[0005] The center of the moving tool is equipped with a positioning sleeve. There are four moving tools evenly distributed around the circumference of the positioning sleeve. The positioning sleeve and the high-speed shaft are connected together by a flat key and a locking nut. The locking nut is threaded to the high-speed shaft to limit the axial movement of the shaft sleeve.

[0006] The disc surface of the tool holder has four evenly distributed fan-shaped holes. The left end face of the tool holder and the vertical edge of the fan-shaped holes serve as the fixed cutting edge, and the moving blade fits together with the left end face of the tool holder.

[0007] A compression spring is sandwiched between the lock cap and the positioning sleeve.

[0008] An ultrasonic transducer is installed on the side of the tool holder facing away from the moving tool.

[0009] The beneficial effects of this utility model are as follows: the installation pipe is installed between the polymer mother liquor preparation tank and the external pump pipeline, with the moving blade facing the preparation tank side. When the polymer mother liquor flows into the installation pipe, the fluid impacts the spiral impeller to rotate. The spiral impeller is accelerated by the reducer, and the moving blade rotates at high speed. The moving blade and the fixed blade work together to cut the "fish eyeballs" into pieces, preventing the uncured polymer from accumulating in the impeller of the external pump and fusing into large clumps, thereby clogging the impeller.

A bushing 42 is provided on the right side of the tool holder 4. A through hole 421 is machined in the bushing 42. The reducer 6 is connected to the bushing 42 by bolts. The reducer 6 is a coaxial reduction mechanism. The high-speed shaft 9 of the reducer 6 passes through the through hole 421 of the bushing 42 to the left and is connected to the moving knife 5. The low-speed shaft 10 of the reducer 6 is connected to a spiral impeller 7 by a flat key and a retaining ring. The retaining ring provides axial limit for the spiral impeller 7.

[0015] The moving cutter 5 has a positioning sleeve 51 at its center. There are four moving cutters 5 evenly distributed around the circumference of the positioning sleeve 51. The positioning sleeve 51 and the high-speed shaft 9 are connected together by a flat key and a locking cap 11. The locking cap 11 is threaded to the high-speed shaft 9 to limit the axial movement of the positioning sleeve 51.

[0016] The disc surface of the tool holder 4 has four evenly distributed fan-shaped holes 41. The left end face of the tool holder 4 and the vertical edge of the fan-shaped holes 41 serve as the fixed cutting edge 411. The moving tool 5 is attached to the left end face of the tool holder 4.

[0017] The installation pipe 1 is installed between the polymer mother liquor configuration tank and the external delivery pump pipeline, the moving knife 5 is towards the configuration tank side, when the polymer mother liquor flows into the installation pipe 1, the fluid impacts the spiral impeller 7 to rotate, the spiral impeller 7 is accelerated by the reducer 6, the moving knife 5 rotates at high speed, the moving knife 5 and the fixed knife edge 411 jointly cut the "fish eye ball" to avoid the unripened polymer to gather in the impeller of the external delivery pump and fuse into large glue balls, thereby plugging the impeller.

[0018] The lock cap 11 and the positioning sleeve 51 are clamped with the compression spring 12, the moving knife 5 and the knife holder 4 are more closely attached, the shearing effect is improved.
