Abstract
The invention discloses a material separation and pushing device for a centrifugal dehydrator. The device mainly comprises a material separation disc, a centerless spiral pusher, a material stop ring, a transmission shaft, a bearing and the like; the internal of the material separation disc is divided into six cavities, and is driven by the transmission shaft to rotate; a material uniformly enters the cavities of the material separation disc through material inlets; the material separation disc rotates; the material is dispersed in the inner wall of a rotating drum under the effect of centrifugal force; and the sputtered material is suffered from secondary centrifugating effect of the material stop ring, is dehydrated and concentrated on the inner wall of the rotating drum, and is pushed out from a discharge port under thrust of the centerless spiral pusher. The device serves as a material scattering device of centrifugal dehydration equipment to uniformly scatter the material, can directly send waste water, sludge and the like entering the centrifugal dehydrating equipment to the inner wall of the rotating drum, and uses the centerless spiral pusher for replacing a center spiral pusher to reduce disturbance of solution on the inner wall of the rotating drum.
Description
Technical field
The invention belongs to mechanical equipment technical field, be specifically related to a kind of sub-material pusher for centrifugal dehydrator.
Background technology
Along with the requirement of environmental conservation is improved constantly by China, sanitary sewage, steel wastewater, cement plant muddy water etc. are required for sludge dewatering treatment.
Horizontal spiral centrifuge has dewatering efficiency height, can continuous operation, dehydration rate advantages of higher obtain a wide range of applications, but combination is generally thought in horizontal spiral centrifuge sewage charging conventional at present with augers, and water inlet is inside augers. This mode feed is simple, but also occurs in that some problems.
Firstly, since augers rotary speed is relatively slow, centrifugal action is limited, and material is difficult to be thrown out of augers by centrifugal action and enters rotary drum, if material concentration is relatively big and when having certain stickiness, very easily causes the blocking of discharging opening in augers; Secondly as discharging opening generally sets the stage casing of augers in augers, the clear liquor unavoidably mud, moisture cleared causes stirring, affects disintegrate-quality; Again, for horizontal screw centrifugal dehydration device, it is uneven that this feed mode easily causes feed dispersion, it is easy to causes the bias of rotary drum, it is easy to causes the abrasion of rotary drum rotating shaft, and produces bigger noise etc.
Summary of the invention
Therefore, and the present invention produces to solve the problems referred to above, first, by the design of material separating disc, makes sub-material uniform, and material separating disc rotates with not being in the mood for augers differential, can improve its rotating speed, it is prevented that Gu material causes the obstruction of material separating disc; Employing is not in the mood for augers and is replaced intentionally augers, reduces the secondary to being centrifuged solid material and disturbs, can improve dehydration water quality accordingly.
A kind of sub-material pusher for centrifugal dehydrator, primary structure includes material separating disc, is not in the mood for augers, blocking material ring, power transmission shaft, bearing etc.; Described material separating disc has 6 sub-material chambeies, inclined sector, it is simple to admittedly expect dispersion; Described material separating disc is connected with blocking material ring by bolt, solid material porch on material separating disc is provided with bearing, auxiliary material separating disc rotates, blocking material ring and described be not in the mood between screw impeller to leave gap, it is not in the mood for augers to be driven by power transmission shaft, relative material separating disc low speed transfers, and pushes the solid material of dehydration.
There is constant slope around blocking material ring, and rotate with material separating disc, when material drops on material separating disc, by centrifugal action, can again make material drop on rotating cylinder.
Accompanying drawing explanation
Fig. 1 is axial view of the present invention.
1 bearing, 2 material separating discs, 3 blocking material rings, 4 it is not in the mood for augers, 5 power transmission shafts.
Fig. 2 is material separating disc of the present invention.
Fig. 3 is material separating disc sectional view.
Fig. 4 is not for being in the mood for augers.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
A kind of sub-material pusher for centrifugal dehydrator, primary structure includes bearing 1, material separating disc 2, blocking material ring 3, is not in the mood for augers 4, power transmission shaft 5; Described material separating disc 2 is connected with blocking material ring 3 by bolt, solid material porch on material separating disc 2 is provided with bearing 1, auxiliary material separating disc 2 rotates, blocking material ring 3 and described be not in the mood between screw impeller 4 to leave gap, it is not in the mood for augers 4 to be driven by power transmission shaft 5, relative material separating disc 2 low speed transfers, and pushes the solid material of dehydration.
During work, material separating disc 2 rotates, and starts charging. Material enters in material separating disc 2 cavity, material separating disc high speed rotating, material can uniformly enter in 6 cavitys of material separating disc 2, then pass through the rotary centrifugal force of material separating disc 2, material dispersion is to rotating cylinder inwall, the rotating cylinder of high speed rotating carries out mud-water separation by centrifugal action, and the solid material mud under cored screw pusher 4 pushes turning cavity wall is sent from discharging opening.
Claims (2)
1., for the sub-material pusher of centrifugal dehydrator, primary structure includes material separating disc, is not in the mood for augers, blocking material ring, power transmission shaft, bearing etc.; Described material separating disc has 6 sub-material chambeies, inclined sector, it is simple to admittedly expect dispersion.
2. device according to claim 1, it is characterised in that blocking material ring and described be not in the mood between screw impeller to leave gap, be not in the mood for augers and driven by power transmission shaft, relative material separating disc low speed transfers, and pushes the solid material of dehydration.
