Abstract
The utility model discloses a large cone-angle pyramid segment rotary drum of a decanter centrifuge, which comprises a straight segment cylinder, a pyramid segment cylinder and a flange plate. The straight segment cylinder, the pyramid segment cylinder and the flange plate are integrated centrifugal casting parts; the shape of the pyramid segment cylinder is of an open horn shape formed from the joint of the pyramid segment cylinder and the straight segment cylinder; the horn-shaped inside of the pyramid segment cylinder is provided with a wear-resistant strip in a matched mode; and a half cone angle of the pyramid segment cylinder is in the range of 13 to 15 degrees. Compared with the prior art, the utility model has the beneficial effects that the very suitable half cone angle is selected, so that the large cone-angle pyramid segment rotary drum is ensured to be beneficial to solid-phase dehydration, the consideration to low spiral pushing power and low wear speed of a helical blade is given, and the sediment conveying effect is greatly improved.
Description
Technical field
The utility model relates to the parts of horizontal screw centrifuge, is specifically related to a kind of awl section rotary drum.
Background technology
Awl section rotary drum is one of key components and parts during horizontal screw centrifuge is made, the cone angle of awl section rotary drum has significant effects to the performance of solid flow, because action of centrifugal force, also has flow tendency backward when being fed forward when particle arrival drum inner wall and by spiral, and the speed that flows backward is also relevant with the angle of helix, is embodied on the cone angle at last.Both produce directly influence to the transportation performance of solid particle, promptly along with the increase of back-flow velocity then the speed of Solid Conveying and Melting descend.Coning angle is big, and sediment is just big at the centrifugal pressure that dry section is subjected to, and helps the sediment dehydration.Though the cone angle of rotary drum is big, help the dehydration of solid phase, the pusher power of spiral can increase, and the rate of wear of helical blade also can strengthen.The rotary drum semi-cone angle of general dewatering centrifuge is at 9～12 °, and such cone angle can not obtain the conveying effect of best sediment.
The utility model content
The utility model has overcome the deficiencies in the prior art, a kind of auger pyramid section rotary drum of horizontal screw centrifuge is provided, it is very reasonable that the semi-cone angle number of degrees of this awl section rotary drum are selected for use, promptly guaranteed to help the solid phase dehydration, taken into account simultaneously and allowed the pusher power of spiral not be big especially, the rate of wear of helical blade neither be fast especially, and the conveying effect of sediment is greatly enhanced.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of auger pyramid section rotary drum of horizontal screw centrifuge, comprise straight section cylindrical shell, awl section cylindrical shell and ring flange, the shape of described awl section cylindrical shell is from tubaeform with the opening of straight section cylindrical shell junction, awl section cylindrical shell is trumpet-shaped inboard and is equipped with wear rib, and the semi-cone angle of awl section cylindrical shell is 13 to 15 degree.
Further technical scheme is:
The semi-cone angle of awl section cylindrical shell is 15 degree.
Described straight section cylindrical shell, awl section cylindrical shell and ring flange are the CrMo steel and form, and are integral body by centrifugal casting.
Have discharging opening on the described straight section cylindrical shell.
Compared with prior art, the beneficial effects of the utility model are: selected most suitable semi-cone angle for use, promptly guaranteed to help the solid phase dehydration, taken into account simultaneously and allowed the pusher power of spiral not be big especially, the rate of wear of helical blade neither be fast especially, and the conveying effect of sediment is greatly enhanced.
Description of drawings
Fig. 1 is the structural representation of the utility model most preferred embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1, a kind of auger pyramid section rotary drum of horizontal screw centrifuge comprises straight section cylindrical shell 1, awl section cylindrical shell 2 and ring flange, and straight section cylindrical shell 1, awl section cylindrical shell 2 and ring flange are the CrMo steel and form, and is integral body by centrifugal casting.The shape of awl section cylindrical shell 2 is from tubaeform with the opening of straight section cylindrical shell 1 junction, and awl section cylindrical shell 2 is trumpet-shaped inboard and is equipped with wear rib 3, and the semi-cone angle of awl section cylindrical shell is 13 to 15 degree (being preferably 15 degree).On straight section cylindrical shell 1, also have discharging opening 4.
