Description

Technical Field

[0001] The utility model relates to a sampling device, in particular to a limestone dry powder sampling device. Background Art

[0002] Currently, limestone powder is typically delivered via sealed dump trucks and pumped into limestone silos for storage. This requires sampling and testing of each truckload. The existing sampling method involves connecting a sampling tube to the conveying pipeline connecting the tanker to the limestone silo and installing a manual valve on the sampling tube. Multiple sampling is required per tanker, and for each sampling, the sampler opens the manual valve, allowing the dry limestone powder to be discharged from the sampling tube. Because the conveying pipeline is pressurized, opening the sampling tube can cause splashing of dry limestone powder, polluting the environment and affecting the health of the samplers.

[0018] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0019] like Figure 1 、 2As shown, the present invention includes a dry powder delivery tanker 2 and a dry powder silo 1. The dry powder delivery tanker 2 and the dry powder silo 1 are connected by a dry powder delivery pipe 4. A sampling pipe 5 is connected to the dry powder delivery pipe 4. The other end of the sampling pipe 5 is connected to the sampling tank body 3. A feed valve 6 is installed on the sampling pipe 5. The bottom of the sampling tank body 3 is connected to a discharge pipe 14, and a discharge valve 13 is installed on the discharge pipe 14. An exhaust pipe 15 is connected to the side wall of the sampling tank body 3, and the end of the exhaust pipe 15 is connected to a dry powder filtering mechanism. A dry powder interception mechanism is provided in the sampling tank body 3 to prevent dry powder from entering the exhaust pipe 15 and can be flipped to allow the dry powder to fall into the discharge pipe 14.

[0020] The dry powder interception mechanism includes a circular frame 7 adapted to the cross-sectional size of the sampling tank body 3, and a filter screen 8 is installed on the circular frame 7. The circular frame 7 is rotatably connected to the inner wall of the sampling tank body 3 through a rotating shaft, and the rotating shaft on one side passes through the sampling tank body 3 and is connected to the drive assembly.

[0021] In this embodiment, the drive assembly includes a cylinder 11 and a rack 9. The cylinder body of the cylinder 11 is fixed to the outer wall of the sampling tank 3, and the rack 9 is fixed to the piston rod of the cylinder 11. A gear 10 is mounted on the rotating shaft and meshes with the rack 9. The cylinder 11 provides power to move the rack 9. When the rack 9 is raised or lowered, it drives the annular frame 7 to flip, thereby achieving unloading.

[0022] In this embodiment, the dry powder filtration mechanism includes a filtered water tank 16. The end of an exhaust pipe 15 extends into the filtered water tank 16 and is located below the water surface. An exhaust port 17 is provided on the top surface of the filtered water tank 16, and a sewage outlet 18 is provided on the bottom surface of the filtered water tank 16. Exhaust pipe 15 serves to relieve exhaust and pressure. A small amount of dry limestone powder carried by exhaust pipe 15 remains in the filtered water tank 16, while clean air is discharged through exhaust port 17. Furthermore, a valve is installed on sewage outlet 18.

[0023] In this embodiment, the connection position between the exhaust pipe 15 and the sampling tank body 3 is located below the circular frame 7 .

[0024] In this embodiment, in order to facilitate the collection of dry limestone powder into the discharge pipe 14 , the upper end of the discharge pipe 14 is connected to the collecting hopper 12 , and the upper end of the collecting hopper 12 is connected to the sampling tank 3 .

[0025] During sampling, the feed valve 6 is opened and the discharge valve 13 is closed. Air carrying dry limestone powder enters the sampling tank 3 through the sampling tube 5. The filter 8 intercepts the dry limestone powder, preventing it from entering the exhaust pipe 15 in large quantities. The filtered air is then discharged through the exhaust pipe 15. After multiple samplings, the feed valve 6 is closed and the discharge valve 13 is opened. A certain amount of dry limestone powder is collected on the filter 8. The drive assembly then rotates the annular frame 7, causing the dry powder to fall into the discharge pipe 14, completing the sampling operation.

[0026] The present application utilizes the dry powder intercepting mechanism and the dry powder filtering mechanism in conjunction with the structural optimization design of the sampling tank 3, thereby effectively avoiding the generation of dust during the sampling process and facilitating sampling.
