The screw conveyer is a machine which utilizes a motor to drive a screw to rotate and push materials so as to realize the conveying purpose. The conveying device can convey horizontally, obliquely or vertically, and has the advantages of simple structure, small cross section area, good sealing property, convenience in operation, easiness in maintenance, convenience in closed transportation and the like. The spiral conveyor is divided into a shaft spiral conveyor and a shaftless spiral conveyor in the conveying form, and is divided into a U-shaped spiral conveyor and a tubular spiral conveyor in the appearance. The shaftless screw conveyor is suitable for dry powder materials without viscosity and small particle materials (such as cement, fly ash, lime, grains and the like), and the shaftless screw conveyor is suitable for materials with viscosity and easy entanglement (such as sludge, biomass, garbage and the like). The working principle of the screw conveyor is that the rotating screw blade pushes the material to be conveyed by the screw conveyor, so that the force of the material not rotating together with the screw conveyor blade is the self weight of the material and the frictional resistance of the screw conveyor shell to the material. The spiral blades are welded on the rotating shaft of the spiral conveyor, and the surface types of the blades have solid surface types, belt surface types, blade surface types and the like according to different conveyed materials.

The pitch between the helical blade of current horizontal (horizontal) screw conveyer is fixed unchangeable usually, and this under the unstable condition of feeding, can appear not being full of the problem of material completely between the helical blade for the material volume of carrying of every rotatory round is inconsistent, thereby can not realize accurate ration ejection of compact.

Drawings

To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

Fig. 1 is a schematic view of a screw conveyor of the present invention.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1, the screw conveyor includes a tubular housing 1, a motor (not shown), a rotating shaft 2 and a helical blade 3, the housing 1 has a feed port 11 and a discharge port 12, the rotating shaft 2 is inserted into the housing 1 and one end of the rotating shaft is in driving connection with the motor, and the helical blade 3 is fixedly disposed (e.g., welded) on the rotating shaft 2 and is divided into a first helical section 31, a second helical section 32 and a third helical section 33 which are sequentially arranged from the feed port 11 to the discharge port 12. Specifically, the first spiral section 31 is disposed below the feed port 11, the third spiral section 33 is disposed adjacent to the discharge port 12, and the second spiral section 32 is located between the first spiral section 31 and the third spiral section 33. Wherein the thread pitches d1, d2 and d3 of the first, second and third

helical segments

31, 32 and 32 are decreased. In one embodiment, the pitch d1 of the first helical segment 23 is 50 mm, the pitch d2 of the second helical segment 24 is 40 mm, and the pitch d3 of the third helical segment 25 is 30 mm. Due to the decreasing pitch, the helical blades of the third helical section 31 can be completely filled with material. Namely, the output material amount is the same every time the screw conveyer rotates one circle, thereby realizing the accurate quantitative conveying of the material.

In the illustrated embodiment, the first, second and third

helical segments

31, 32, 33 are of decreasing length. I.e. the first spiral segment 31 is longest and the third spiral segment 33 is shortest. Of course, the lengths of the first, second and third

helical segments

31, 32 and 33 are not limited thereto.

Preferably, the spiral blade profile of the first spiral segment 31 is a belt profile, and the spiral blade profiles of the second and third spiral segments 32 and 33 are solid profiles. That is, the helical blades of the first helical section 31 are welded to the rotating shaft 2 through several connecting rods, and the helical blades of the second helical section 32 and the third helical section 33 are directly welded to the rotating shaft 2.

In the illustrated embodiment, the end of the third spiral section 33 near the discharge hole 12 is provided with a movable roll-over plate 4, and the movable roll-over plate 4 is configured to be capable of being rolled over only in a direction away from the third spiral section 33. The movable turnover plate 4 is pushed open by the material during feeding, which can ensure that the material can stably enter the discharge hole 12.

Preferably, the screw conveyor may further include a reverse screw section 34, and the reverse screw section 34 and the movable flipping plate 4 are respectively located at both sides of the discharge hole 12. Since the reverse spiral section 34 has a spiral direction opposite to that of the third spiral section 33 and is located on both sides of the discharge port 12, the reverse spiral section 34 and the third spiral section 33 both convey the material toward the discharge port 12 during feeding, which prevents the material from being accumulated.

In addition, the housing 1 may be further provided with a movable access opening 13, and the movable access opening 13 is disposed to be radially opposite to the discharge port 12. The worker can handle the problem that the discharge hole 12 is blocked through the movable access hole 13.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
