After being transported through a long-distance pipeline, the unloading function of the pumped material is completed. A rotating motor 3 is fixed on the outer wall of one side of the mixing box 2 through a tripod. The model of the rotating motor 3 is a Y80M1-2 motor, which can provide necessary power support for the rotation of the stirring rod 203. One side of the mixing box 2 is connected to a feeding device 4 through a conveying pipeline 402. The feeding device 4 provides high pressure through a reciprocating pump, thereby forcing the original material that the device needs to handle to be transported to the mixing box 2 at a distance through a long-distance conveying pipeline 402, and the subsequent unloading work is completed after on-site mixing and stirring, thereby avoiding long-term transportation. The paste material is blocked, which affects the construction. A steam furnace 5 is fixed on the other side of the mixing box 2. The steam furnace 5 can provide steam for the device, and then use high-pressure steam to regularly purge the nozzle 601 to avoid excessive viscosity of the material, keep the feed pipeline and the nozzle 601 unobstructed, and then complete the unloading. In addition, high-pressure steam is used to steam purge the upper feed pipeline and the aggregate box 1 to avoid clogging the feed pipeline and the aggregate box 1 due to silting, drying, and agglomeration of the material in the aggregate box 1 and the feed pipeline, so as to ensure smooth unloading of the feeder. A purge device is installed above the steam furnace 5 through a gas pipeline. 7. The purge device 7 controls the conveying direction and conveying size of the high-pressure steam in the steam furnace 5, thereby unblocking the unloading process of the entire device, avoiding the accumulation and drying of materials inside the pipeline during the unloading process, and ensuring the smooth unloading pipeline. The interior of the purge device 7 is equipped with a first steam outlet 701 and a second steam outlet 702 through a gas pipeline, and the second steam outlet 702 is located below the first steam outlet 701.

An upper purge valve 703 is installed in the middle of the connecting pipeline between the first steam outlet 701 and the second steam outlet 702. The upper purge valve 703 is used to control the delivery of high-pressure steam to the mixing box 2 and the feed pipeline, which plays a role in unblocking the upward process flow. A lower purge valve 704 is installed on the gas pipeline on one side of the second steam outlet 702.

When there is no more material to be replenished in the collecting box 1, the support column 103 rebounds upward, and the material in the collecting box 1 can slowly enter the collecting pipe 104 through the height difference between the baffle 102 and the collecting pipe 104, thereby avoiding the adverse effects of high-pressure injection; the collecting pipe 104 can evenly deliver the material entering the collecting box 1 to the unloading device 6 to ensure the consistency of the feed amount inside the unloading device 6; the lower feed valve 105 is mainly used to control the downward feeding of the material and adjust the amount of feeding.

[0025] Working principle: When the staff uses this device to carry out material discharge work, they first use the feeding device 4 to send the pre-configured mixed material into the mixing box 2 to complete the mixing, and then enter the collecting box 1 for buffering treatment and complete the long-distance uniform discharge work through the discharge device 6. In this process, the purge device 7 can use the steam generated by the steam furnace 5 to complete the dredging work of the entire feeder, avoiding the drying and clogging of the material during the downward transportation process, and ensuring the smooth discharge pipeline of the entire feeder.
