Through loading and unloading operations, the usage quantity of bulk cement tanks and barite powder tanks in cementing operations is minimized, so as to meet the working condition requirements of narrow site at the cementing operation site in oil fields.

[0003] The composition and performance of a vertical ash discharging tank may vary due to different storage time and storage environment, which may affect the effect of cementing operations. Therefore, it is necessary to conduct irregular sampling detection on dusty materials such as cement in the vertical ash discharging tank. Most vertical ash discharging tanks on the market do not have special sampling detection devices. Samples are directly taken with sampling bags from the ash outlet during the unloading operation of the ash discharging tank, which is not only inconvenient to operate, but also cannot timely detect and handle when there are differences in material components in the ash discharging tank.

[0004] Therefore, it is necessary to develop a sampling device to solve the above problems existing in the existing sampling method for vertical ash discharging tanks. Summary of the Invention

[0015] One end of the communication pipe 1 is equipped with the switch valve 2. The other end of the communication pipe 1 is welded to the ash discharge pipeline of the vertical ash discharge tank and kept in communication therewith (refer to the description attached Figure 1 ).

[0016] One end of the switch valve 2 is equipped with the quick coupling A 3 (refer to the description attached Figure 2 and 3 ). The quick coupling A 3 is of a hollow tubular structure; one end of the quick coupling A 3 is fixedly connected to the switch valve 2; a limiting annular ridge 11 is arranged on the circumferential surface of the other end of the quick coupling A 3; a locking ring groove 9 is arranged on the circumferential surface of the quick coupling A 3 on one side of the limiting annular ridge 11; an avoiding notch 10 is arranged on the quick coupling A 3 on one side of the locking ring groove 9 (refer to the description attached Figure 4 and 5 ).

[0017] The upper end of the sample tank 4 is equipped with the quick coupling B 5 (refer to the description attached Figure 2 and 3 ). The quick coupling B 5 is of a stepped tubular structure; one end of the quick coupling B 5 is in communication with the sample tank 4; a sealing ring 13 is installed on the stepped surface inside the quick coupling B 5 through an assembly ring groove 12; locking wrenches 16 are symmetrically installed on the quick coupling B 5 through through holes 14 and rotating pins 15 (refer to the description attached Figure 5 ). The locking wrench 16 is of an L-shaped structure; an arc-shaped extrusion protrusion 17 is arranged at the lower end of the locking wrench 16 (refer to the description attached Figure 5 and 9 ).

[0018] A marking line is arranged on the circumferential surface of the quick coupling B 5 on one side of the locking wrench 16; during operation, after aligning the marking line with the avoiding notch 10 on the quick coupling A 3 or the sealing cover 7, the quick coupling B 5 is inserted and connected with the quick coupling A 3 or the sealing cover 7.

[0019] The sealing cover 7 is connected to one side of the quick coupling B 5 through a connecting rope 6 (refer to the description attached Figure 2 and 3 ). The sealing cover 7 is a revolving body with a convex-shaped cross section; a locking ring groove 9 is arranged on the circumferential surface of the thin end of the sealing cover 7; an avoiding notch 10 is arranged on the sealing cover 7 on one side of the locking ring groove 9 (refer to the description attached Figure 6 and 7 ).

[0020] The bottom of sample container 4 is connected to a vent valve 8 (see instruction manual appendix). Figure 2 and 3 Quick-connect coupling B5 can be connected to quick-connect coupling A3 or sealing cap 7.

[0021] When sampling with this vertical ash hopper outlet pipeline sampling device, first align quick-connect connector B5 with quick-connect connector A3, at which point the locking wrench 16 corresponds to the clearance slot 10 on quick-connect connector A3; then insert quick-connect connector B5 onto quick-connect connector A3, so that the lower end of the locking wrench 16 is located inside the locking ring groove 9; then rotate quick-connect connector B5 to displace the lower end of the locking wrench 16 from the clearance slot 10 (see the instruction manual appendix). Figure 3 and 5 After completing the above steps, rotate the locking wrench 16.

It can connect the sample container 4 to the ash discharge pipeline of the vertical ash hopper via a quick connection through the connecting pipe 1. In this way, the material in the ash discharge pipeline will enter the interior of the sample container 4 under the pressure inside the hopper. Then, the switch valve 2 is closed, and the sample container 4 can be removed to complete the sampling work. This solves the problems of inconvenience in operation and inability to directly sample from the inside of the existing vertical ash hopper sampling method, and is particularly suitable for the needs of vertical ash hopper sampling.
