Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, and particularly relates to a spiral feeding conveyor. Background Art

[0002] In the process of fly ash sintering treatment, for the front-feed system of a fly ash boiler, a spiral feeding conveyor is often used. A spiral feeder generally consists of a conveyor body, inlet and outlet openings, and a driving device. The conveyor body is composed of a rotating shaft, spiral blades, and a trough. The rotating shaft is installed on the bearing seats at both ends of the trough through bearings. When biomass fuel is added from the feed inlet, as the rotating shaft is driven by the motor to rotate, the fuel is pushed forward by the spiral blades, thus completing the feeding operation to the boiler.

[0003] In the process of fly ash sintering treatment, biomass fuel and binder are conveyed through a spiral feeder, and then stirred by a mixer and enter the fly ash boiler for combustion. Usually, during the conveying process, only one kind of material can be conveyed before conveying another kind of material. At the same time, due to different materials, sizes, shapes, states, etc. of the materials, they cannot be conveyed through one spiral feeder simultaneously, thus affecting the conveying efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a spiral feeding conveyor, which can solve the problem of unable to convey different materials simultaneously by rotating the first blade and the second blade to convey materials.

[0005] The utility model is realized through the following technical solutions:

[0006] A spiral feeding conveyor includes a feeding housing and legs. The legs are fixedly connected to the feeding housing. The feeding housing is provided with a first feed inlet and a second feed inlet. A driving motor is fixedly connected to the feeding housing. The output shaft of the driving motor movably penetrates the feeding housing. A conveying component for conveying raw materials is arranged inside the feeding housing. The output shaft of the driving motor is fixedly connected to the conveying component. A connection port is arranged at the bottom of the feeding housing. A mixing chamber is arranged at the connection port. The mixing chamber is provided with a discharge port. It should be noted that in the prior art, a spiral feeder cannot convey materials with different materials, sizes, shapes, states, etc. simultaneously through one spiral feeder, thus affecting the conveying efficiency.

[0007] In view of the above situation, a spiral feeding conveyor is proposed. Specifically, different materials are conveyed through the conveying component, thereby increasing the conveying efficiency. At the same time, the materials are preliminarily mixed through the mixing chamber, thereby improving the conveying quality of the materials.

The rotating shaft is provided with a first blade and a second blade, and a pushing piece is also fixedly connected to the rotating shaft. By rotating the first blade and the second blade, different materials are conveyed to the connection port, and by rotating the pushing piece, different materials are simultaneously pushed into the mixing bin, and the materials are preliminarily mixed in the mixing bin, thereby enhancing the uniformity between the materials.

[0009] Furthermore, the mixing bin includes a stirring motor, and the output shaft of the stirring motor movably penetrates through the mixing bin and is fixedly connected to a stirring component.

[0011] Furthermore, an adjusting component is provided at the discharge port, and the adjusting component is fixedly connected to the discharge hopper. The conveying amount of the fuel is controlled by the adjusting component to stably and continuously convey the fuel.

[0012] Furthermore, the adjusting component includes an adjusting cover, which is fixedly connected to the mixing bin. The adjusting cover is movably connected to a limiting rod, a spring is fixedly connected to the limiting rod, and the spring is fixedly connected to the inner wall of the adjusting cover. A ratchet is also provided in the adjusting cover, and the ratchet is fixedly connected to an adjusting shaft. The adjusting shaft movably penetrates through the adjusting cover, and a gear is fixedly connected to the adjusting shaft. The gear is movably connected to a rack, and a baffle is fixedly connected to the rack. The baffle is slidably connected to the mixing bin. By rotating the ratchet to drive the adjusting shaft, the adjusting shaft rotates to drive the gear to rotate. The gear meshes with the rack, thereby driving the rack to move. The rack is fixedly connected to the baffle, thereby driving the baffle to move up and down, thereby controlling the conveying amount of the materials.

[0013] Furthermore, a handle is provided on the adjusting shaft. By holding the handle and rotating the handle, the adjusting shaft is driven.
