Description

Technical Field

[0001] The utility model belongs to the technical field of barrel silo cleaning equipment and relates to a device for eliminating silo bulges, in particular to a movable device for eliminating silo bulges. Background Art

[0002] Affected by factors such as weather and coal characteristics, silos may become arched or blocked during use, causing the silo to be unable to work normally. At present, the elimination of arches and blockages is mostly done by air cannon dredging, mechanical vibration (knocking) dredging, mechanical movement (or rotation) dredging, etc. These types of dredging equipment are installed at the iron conical outlet. However, the outlet of the coal storage silo is annular with a long outlet circumference, the silo is a reinforced concrete structure, the silo wall is thick, and the position of the blockages in the coal storage silo is not fixed. These characteristics of the silo make the existing dredging devices and dredging methods unable to effectively solve the problem of arches and blockages in the silo. When the equipment and tools cannot effectively remove the blockages, some silo users will manually enter the silo to break the arches and eliminate the blockages. This method not only has a poor working environment and high labor intensity, but also has the risk of major accidents such as the collapse of the blockages during the dredging process, causing casualties.

[0003] Therefore, it is necessary to provide a device to safely and effectively solve the problem of coal arching inside the silo. Utility Model Content

[0024] Specifically, Figure 2 As shown, the head puff-eliminating part 1 includes a mechanical arm 5, an adjustable bracket 6, a high-pressure nozzle 7, a visual mechanism, and a head connecting pipe. A through hole is set in the middle of the adjustable bracket 6, and the high-pressure nozzle 7 is passed through. A limit block is set on the side of the high-pressure nozzle 7, which is in contact and connected with the adjustable bracket 6 through the limit block, and has the freedom to rotate or swing relative to the adjustable bracket 6. In this embodiment, since the limit block needs to surround the outer wall of the high-pressure nozzle 7 in a whole circle, in order to facilitate material collection, two nuts are selected in this embodiment: nut A111 and nut B112 are respectively fixed on the upper and lower parts of the high-pressure nozzle 7. In this embodiment, the upper end of the high-pressure nozzle 7 is the water outlet end, and the lower end is connected to the pressurizing part 2 through the head connecting pipe, and the pressurizing part 2 is used to provide high-pressure water force for the high-pressure nozzle 7. Among them, the head connecting pipe is a high-pressure hose, and the staff can choose the length of the high-pressure hose according to the specific needs of the position of extending into the silo 21. The visual mechanism is arranged on the adjustable bracket 6, and the visual area of ​​the visual mechanism points to the spraying area of ​​the high-pressure nozzle 7, which is used to help the staff outside the silo 21 observe the arched coal and the arch broken and deflated coal in the barrel. The mechanical arm 5 is fixedly connected to the adjustable bracket 6. The mechanical arm 5 in this embodiment is selected to be rod-shaped, so as to facilitate the staff to operate. Driven by the mechanical arm 5, the adjustable bracket 6 has the freedom to extend into the silo 21 and retract from the silo 21.

[0025] In addition, for the convenience of observation, the visual mechanism in this embodiment includes a lighting lamp 8 and a camera 9 arranged on the adjustable bracket 6 through a mounting seat 12, wherein the camera 9 is specifically selected as a spherical camera, and a display screen is arranged on the control unit 4. The spherical camera is communicatively connected with the display screen, and the captured image is transmitted to the display screen for observation by the staff. The setting of the spherical camera can further facilitate the staff to observe the specific situation in the silo 21.

[0026] Furthermore, in order to facilitate the adjustment of the spray angle of the high-pressure nozzle 7 so that the fluffy coal at different angles in the silo 21 can be removed smoothly, the head fluff removal part 1 in this embodiment also includes at least one retractable push rod 10. In this embodiment, there are two retractable push rods 10. The type of the retractable push rod 10 can be hydraulic or electric, and the staff can choose according to the actual situation. The two ends of the retractable push rod 10 are respectively hinged to the inner side of the adjustable bracket 6 and the outer wall of the high-pressure nozzle 7. When the angle of the high-pressure nozzle 7 needs to be adjusted, the control unit 4 is used to control the retractable push rod 10 to extend or retract a certain distance.

[0028] like Figure 4 As shown, the water recycling part 3 includes a lifting pump 19, a filter, a circulating water tank 20 and a diversion loop. The diversion loop is connected between the outlet of the clean water flowing out of the silo 21 and the water inlet of the circulating water tank 20, and is used to collect the cleaned water into the circulating water tank 20. The filter is arranged on the pipeline connected to the water inlet of the lifting pump 19. The water outlet of the lifting pump 19 is connected to the pressurizing part 2 through a pipeline, and is used to transport the filtered and purified water to the pressurized water tank 14 for its recycling.
