Abstract
The utility model discloses a horizontal spiral centrifuge which comprises a shell. A drum is arranged in the shell, a spiral propeller and the drum are coaxial, a rotation shaft of the spiral propeller is an empty shaft, one end of the empty shaft is provided with a raw material inlet, a raw material outlet communicated with the empty shaft is arranged on the portion of the empty shaft positioned inside the drum, a material outlet is arranged at a push-off end of the spiral propeller on the drum, and a clear liquid outlet is arranged at one end opposite to the material outlet on the drum. The horizontal spiral centrifuge is characterized in that a hot air channel is arranged on the shell and corresponds to the material outlet, and cleaning holes are arranged on the drum. Compared with the prior art, the horizontal spiral centrifuge has the advantages that hemi-hydrate gypsum is prevented from reducing, and the centrifuge is smooth in work and fine in effect.
Description
Technical field
The utility model relates to a kind of centrifuge, is specially a kind of horizontal spiral centrifuge with hot air duct and clean-out opening.
Background technology
When making high strength gypsum, at first need to prepare alpha semi-hydrated gypsum, i.e. calcium sulphate dihydrate, the problem that the centrifugal rear existence of calcium sulfate is reduced causes the calcium sulfate of production can not satisfy the requirement of industry, high strength gypsum remitted its fury.
Secondly, after centrifuge worked long hours, the inwall semi-hydrated gypsum of rotary drum easily overstock and forms a heavy wall, in the course of time, itself and the mutual friction of spiral propeller phase cause the wearing and tearing of spiral propeller, and increased propelling resistance, have a strong impact on the centrifugal work of centrifuge.
Summary of the invention
In order to overcome defects, the utility model provides a kind of horizontal spiral centrifuge, and this centrifuge can have advantages of that the semi-hydrated gypsum of preventing reduces, centrifuge work is smooth and easy, effective.
For achieving the above object, the utility model adopts following technological means:
A kind of horizontal spiral centrifuge, comprise shell, be provided with rotary drum in shell, with the coaxial spiral propeller that is provided with of rotary drum, the rotating shaft of described spiral propeller is empty axle, and an end of empty axle is that feed(raw material)inlet, empty axle are positioned at the rotary drum interior section and are provided with the material outlet that is communicated with empty axle; The distolateral material outlet that is provided with of the release of spiral propeller on rotary drum is provided with purified liquor outlet with a relative end of material outlet on rotary drum; Be provided with hot-air channel corresponding to the material outlet end on described shell; Rotary drum is provided with clean-out opening.
Further, described clean-out opening place straight line is along the rotary drum radial direction.
Further, described clean-out opening is provided with a plurality of, and these a plurality of clean-out openings circumferentially arrange along rotary drum.
Further, described feed(raw material)inlet end and material outlet end are at the same end of centrifuge.
Operation principle of the present utility model and beneficial effect show:
Of the present utility model is that the position that calcium sulphate dihydrate flows out is provided with hot-air channel at material outlet, has effectively stoped the reduction of semi-hydrated gypsum, guarantees the quality of high strength gypsum.
Increase clean-out opening on wall turning of rotary drum, can inwardly fill the water of establishing with pressure, the heavy wall on drum inner wall is peeled off, make it to break away from drum inner wall, reduce frictional force and the loss of spiral propeller, spiral propeller can smooth and easy work, guarantees centrifugal effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Now by reference to the accompanying drawings the utility model is further described, shown in Figure 1.
A kind of horizontal spiral centrifuge comprises base 1, and base 1 is provided with cylindrical case 2.
Be arranged with rotary drum 3 in shell 2, be arranged with spiral propeller 4 with rotary drum 3 in coaxial and rotary drum 3, the rotating shaft of described spiral propeller 4 is the empty axle 41 of hollow structure, and an end of empty axle 41 is feed(raw material)inlet 42, other end shutoff; The part that empty axle 41 is positioned at rotary drum 3 inside is provided with the material outlet 43 that is communicated with empty axle 41.
On rotary drum 3, the release end of spiral propeller 4 is provided with material outlet 5, is provided with purified liquor outlet 6 with a relative end of material outlet 5 on rotary drum 3.
Described empty axle 41 is positioned at release end one side of spiral propeller 4, and namely feed(raw material)inlet 42 ends and material outlet 5 ends are at the same end of centrifuge.
On described shell 2, material outlet 5 ends are provided with hot-air channel 7; Rotary drum 3 is provided with a plurality of clean-out openings 31, and described each clean-out opening 31 place straight line overlap with the radial direction of rotary drum 3, and these a plurality of clean-out openings regular distribution on rotary drum is such as annular array or in spiral distribution.
During use, gypsum liquid enters from empty axle 41, then the feed(raw material)inlet 42 from the empty axle 41 enters in rotary drum 3, then centrifugal under the centrifugal action of spiral propeller 4 and with the semi-hydrated gypsum spiral pushing to material outlet 5, semi-hydrated gypsum enters subsequent processing under the insulation of hot-air channel 7.
In the time of need to cleaning centrifuge, by the inside pressurising hot water of clean-out opening 31, be used for to destroy a gypsum ancient piece of jade, round, flat and with a hole in its centre, in cleaning process, can fill the aided process of hot water with the propelling action of spiral propeller 4 and in the empty axle 41, to increase cleaning performance.
