Embodiment 1

[0026] This embodiment is used to illustrate the screw conveying device provided by the present invention.

[0027]The LS500 screw conveying device purchased from Botou City Meite Cement Machinery Co., Ltd. is improved. The screw conveying device includes a shell, a screw propeller, a driving device, a feeding port and a discharging port. In the improved screw conveying device, the screw propeller is composed of a central shaft and 7 helical blades, the axial length of the central shaft is 3.07 meters, and the diameter of the outer edge of the screw blades of the screw propeller is both 500 mm, the distance between the outer edge of the screw blade and the casing is 20 mm, along the advancing direction of the material in the screw conveying device, the pitch between the first screw blade and the second screw blade is 400 mm mm, and the pitch between the subsequent helical blades is successively increased by 35 mm.

[0028] Using the above-mentioned improved screw conveying de...

Embodiment 2

[0030] This embodiment is used to illustrate the screw conveying device provided by the present invention.

[0031] The LS500 screw conveying device purchased from Botou City Meite Cement Machinery Co., Ltd. is improved. The screw conveying device includes a shell, a screw propeller, a driving device, a feeding port and a discharging port. In the improved screw conveying device, the screw propeller consists of a central shaft and 7 helical blades, the shaft length of the central shaft is 3.07 meters, and the diameter of the inner wall of the casing is 550 mm. In the advancing direction of the screw conveying device, the diameter of the outer edge of the first screw blade is 450 mm, and the diameter of the outer edge of the subsequent screw blades is successively increased by 10 mm; the diameter between the first screw blade and the second screw blade is The pitch between the helical blades is 400 mm, and the pitch between the subsequent helical blades increases by 35 mm.

Abstract

The invention discloses a screw conveyor which comprises a shell (1) and a screw propeller (2) placed in the shell (1); a material inlet (3) and a material outlet (4) are formed at two ends of the shell (1) respectively; the screw propeller (2) comprises a shaft and at least three screw blades; and clearances are reserved between the outer edges of the screw blades and the inner wall of the shell (1). The screw blade comprises a first part and a second part, the screw blades of the first part are the screw blades close to the material inlet (3), the screw blades of the second part are the screw blades close to the material outlet (4), and the screw pitch of the screw blades of the second part is larger than that of the screw blades of the first part. The screw conveyor disclosed by the utility model can be used for remarkably overcoming the problem of material blockage in the shell, greatly reducing the time of shut down for cleaning, and further remarkably improving the production efficiency.

Description

technical field [0001] The invention relates to a screw conveying device. Background technique [0002] Screw conveyors are widely used in material conveying in various fields. The existing screw conveying device usually includes a shell, a screw propeller, a feed port and a material outlet; the screw propeller is located in the shell, and the feed port and the discharge port are located at both ends of the shell; the screw propeller includes a shaft and a material outlet. For the helical blades located thereon, there is a gap between the outer edge of the helical blade and the inner wall of the casing; and all the helical blades form the same pitch. In the existing screw conveying device, there is a gap between the outer edge of the screw blade and the inner wall of the casing. Therefore, when the material is conveyed, as the screw blade advances forward, the material falls to the inner wall of the casing under the action of gravity, thereby As a result, only a part of th...
