Description

Technical Field

[0001] The utility model relates to the technical field of spiral feeding equipment, and particularly discloses a fly ash anti-blocking material feeding device. Background Art

[0002] Fly ash refers to the ash material produced when burning coal. It mainly comes from the solid waste collected from the flue gas after coal combustion. The chemical composition of fly ash mainly includes silicon dioxide, aluminum oxide, ferrous oxide, ferric oxide, calcium oxide and titanium oxide. Fly ash is widely used in building materials, fertilizer processing, road construction and the production of environmentally friendly materials due to its excellent performance. In the process of fly ash processing, a feeding device is required to achieve stable transportation of fly ash, which is convenient for weighing, measuring and quantitative control of fly ash.

[0003] Chinese patent number CN218143924U discloses a screw feeder with an anti-blocking mechanism. The technical solution includes a feed hopper and a feed pipe. The feed hopper is mounted on one side of the top of the feed pipe, a power box is mounted on the end of the feed pipe near the feed hopper, and a blockage prevention box is mounted on the end of the feed pipe facing away from the power box. A feed shaft is mounted in the middle of the feed pipe, and a worm gear is mounted on the outer surface of the feed shaft, located inside the power box. A drive motor is mounted on the top of the power box, near the front surface. A worm is mounted on the output shaft of the drive motor, located in front of the worm gear. Blades are mounted on the outer surface of the feed shaft. The utility model solves the problem that the existing device has no auxiliary mechanism for clearing blockage, and during use, the material is very likely to be blocked inside the feeding pipe, and it is impossible to assist in clearing the blockage, which affects the normal transportation of the raw materials. The utility model reduces the probability of blockage of the raw materials, thereby ensuring the normal transportation of the raw materials. However, the above-mentioned feeder does not have the function of stirring and drying the materials during use, which to a certain extent affects the application scope and use scenarios of the above-mentioned feeder. When the water content in the material to be fed is relatively high, the material is very likely to stick together again when it is screened by the screening net and falls to the bottom of the screening net, which increases the probability of blocking the feeding pipe and the turbine and affects the continuity of the feeding operation. Therefore, in order to solve the above-mentioned problems, the utility model proposes a fly ash anti-blocking material feeding device. Utility Model Content

[0031] The fly ash anti-blocking feeding device disclosed in this embodiment connects the two ends of the heating tube 313 to the controller 4 via power cords before use, connects the original material receiving device to the first discharge pipe 211, and selects the role of the storage bin 31 according to actual use requirements. When mixing and drying are not required, the storage bin 31 is only used as a storage structure for fly ash. The controller 4 is used to control the extension of the telescopic rod 34 to push the blocking plate 33 into the second discharge pipe 312, blocking the second discharge pipe 312, and injecting a sufficient amount of fly ash into the inner liner 311 from the top of the inner liner 311.

[0032] The controller 4 is used to start the first motor 23 and the second motor 26 in sequence, so that the first motor 23 and the second motor 26 drive the spiral conveying rod 22 and the first stirring rod 25 to rotate respectively, and the controller 4 is used to control the telescopic rod 34 to retract, so that the two ends of the blocking plate 33 slide inside the slide groove 3121, and the blocking plate 33 is pulled out from the second discharge pipe 312, so that the fly ash inside the inner tank 311 is discharged into the feeding pipe 212 through the second discharge pipe 312, and is broken up by the first stirring rod 25 and falls into the feeding barrel 21, and is transported to the end of the feeding barrel 21 away from the feeding pipe 212 through the spiral conveying rod 22, and is discharged from the feeding barrel 21 from the first discharge pipe 211 and falls into the original material receiving device. During the feeding process, the depth of the blocking plate 33 extending into the second discharge pipe 312 can be adjusted by controlling the extension and retraction of the telescopic rod 34, and the discharge speed of the second discharge pipe 312 can be controlled, thereby adjusting the feeding efficiency of the feeding mechanism 2.

After mixing, repeat the above feeding operation to perform the fly ash feeding operation.

[0034] When the water content in the fly ash is relatively high, a sufficient amount of fly ash can be put into the inner liner 311, and the controller 4 is used to start the heating tube 313 to heat the inner liner 311, so that the inner liner 311 transfers heat to the moist fly ash, causing the water in the fly ash to evaporate. The controller 4 is used to start the third motor 38, so that the third motor 38 drives the second stirring rod 35 to rotate through the connecting shaft 37 and the steering gear 36, stirring the fly ash inside the inner liner 311 to ensure that the fly ash is evenly dried. After drying is completed, the heating tube 313 is turned off, and the above feeding operation is repeated to continue the fly ash feeding operation.
