Abstract
The utility model provides a horizontal screw discharging sedimentation centrifuge. The horizontal screw discharging sedimentation centrifuge comprises a screw, and is characterized in that the screw consists of a conical tube, a columnar tube and a squeezing disc, wherein the squeezing disc is a round sheet having a diameter equal to that of the large end of the conical tube; the diameter of the columnar tube is smaller than that of the large end of the conical tube; and the large end of the conical tube and the columnar tube are respectively bonded with the squeezing disc by welding. The horizontal screw discharging sedimentation centrifuge has the advantages of simple structure, high efficiency, low energy consumption, good water removal effect, low material consumption, and long service life.
Description
Technical field
The utility model relates to a kind of horizontal spiral discharge sedimentation centrifuge.
Background technology
Horizontal spiral discharge sedimentation centrifuge is the press type helical-conveyer centrifugal of a kind of full-speed operation, continuous feed and separation, is widely used in industries such as oil, chemical industry, metallurgy, medicine, food, light industry, environmental protection.Is that 535% material separates for solid particle size greater than 10 μ m, concentration, be usually used in the dehydration of mud and concentrate, and be the key equipment of municipal sewage treatment.
Common horizontal spiral discharge sedimentation centrifuge as shown in Figure 1, comprise differential mechanism 1, spiral 2, rotary drum 3, overfall 4, sediment outlet 5, feed entrance 6, wherein differential mechanism 1 links to each other 3 with spiral 2 and rotary drum respectively, spiral 2 places rotary drum 3 inside, and rotary drum 3 small end places have sediment outlet 5, big end place has overfall 4 and feed entrance 6 respectively.At present, produce the horizontal spiral discharge sedimentation centrifuge of utilization at home, its rotary drum 3 and spiral 2 mostly adopt the structure of cylinder awl combination, the column casing of this structure rotary drum 3 and spiral 2 has identical diameter with the big end of circular cone tube, material enters cavity between spiral 2 and the rotary drum 3 from the inner chamber of feed entrance 6 by spiral 2, under centrifugal action, the sediment of formation is pushed to rotary drum 3 small ends by spiral 2 through cone, discharges outside the rotary drum 3 through the sediment outlet 5 of rotary drum 3.The one-level press dewatering that this process has only been passed through spiral awl section dehydration zone for the sediment that requires to have low water capacity, uses the type centrifuge can't reach the dehydration requirement.
Summary of the invention
In order to overcome above-mentioned shortcoming, the utility model provides a kind of simple in structure, efficient energy-saving, low, the good horizontal spiral discharge sedimentation centrifuge of dehydrating effect of cost.
Horizontal spiral discharge sedimentation centrifuge described in the utility model on the basis that does not change common other device of horizontal spiral discharge sedimentation centrifuge, only improves its spiral.Described spiral comprises circular cone tube, cylindrical drum, squeezing dish, wherein the squeezing dish be one with the isometrical disk of the big end of circular cone tube, the diameter of cylindrical drum is less than the diameter of the big end of circular cone tube, the big end of circular cone tube and cylindrical drum respectively with squeezing dish solder bond.
The spiral of horizontal spiral discharge sedimentation centrifuge described in the utility model has following beneficial effect:
1, horizontal spiral discharge sedimentation centrifuge described in the utility model is efficient, energy-conservation, dehydrating effect is good.When sediment through spiral, when squeezing dish place is shifted in the space between cylindrical drum and rotary drum onto, be extruded earlier for the first time concentratedly, be pushed to awl section place then and be extruded once more, discharge from the sediment outlet of rotary drum small end at last.Under the identical situation of centrifugal force, therefore sediment is obtained lower water capacity by twice extruding.
2, horizontal spiral discharge sedimentation centrifuge economical with materials described in the utility model, and the service life of equipment is improved.Because spiral has reduced the cylindrical drum diameter, has reduced the weight of entire machine, spiral has reduced centrifugal force under identical rotating speed.Thereby, reduced the amplitude of machine vibration, disturbance, service life of having improved machine.
In order to reach better effect, can take following measure: squeezing disk center has and the isometrical circular hole of cylindrical drum.Reduced the weight of entire machine like this, spiral has reduced centrifugal force under identical rotating speed.Thereby, reduced the amplitude of machine vibration, disturbance, service life of having improved machine.
Description of drawings
Fig. 1 is the schematic diagram of common horizontal spiral discharge sedimentation centrifuge.
Fig. 2 is the schematic diagram of the novel spiral part of horizontal spiral discharge sedimentation centrifuge described in the utility model.
Number description:
The 1-differential mechanism; The common spiral of 2-; The 3-rotary drum; The 4-overfall; The outlet of 5-sediment; The 6-feed entrance; 7-circular cone tube; The 8-cylindrical drum; 9-squeezing dish; The novel spiral of 10-.
The specific embodiment
In conjunction with Fig. 2, describe horizontal spiral discharge sedimentation centrifuge described in the utility model in detail.This horizontal spiral discharge sedimentation centrifuge except that spiral, other parts, the device all the horizontal spiral discharge sedimentation centrifuge with common is identical.The novel spiral 10 of horizontal spiral discharge sedimentation centrifuge described in the utility model comprises circular cone tube 7, cylindrical drum 8, squeezing dish 9, wherein squeezing dish 9 be one with the isometrical disk of the big end of circular cone tube 7, the diameter of cylindrical drum 8 is less than the diameter of circular cone tube 7 big ends, and the big end of circular cone tube 7 and cylindrical drum 8 are coiled 9 solder bond with squeezing respectively.
When sediment through novel spiral 10, when the space between cylindrical drum 8 and rotary drum 3 is shifted squeezing onto and is coiled 9 places, after pushing, concentrate the first time through squeezing dish 9, the sediment that water capacity is little is pushed to novel spiral 10 awl section places again, carry out the extrusion dehydration second time, discharge in rotary drum 3 segment sediments outlet 5 at last.
Claims (2)
