Abstract
The utility model discloses a spirally-stacked type sludge dehydrating machine. The sludge dehydrating machine is characterized by comprising a hollow cylinder, wherein the cylinder is internally provided with a rotating shaft through which a screw conveyer is driven; an inlet is formed in the upper end of one side of the cylinder and the other end of the cylinder is provided with a backpressure plate; the screw conveyer is divided into two parts which have different pitches, wherein the pitch of one end, close to the inlet, of the screw conveyer is relatively large and the pitch of one end, close to the backpressure plate, of the screw conveyer is relatively small; two water outlet zones are arranged outside the cylinder, a plurality of water outlet holes are formed in each of the water outlet zones along the radial direction of the cylinder, and a sliding sleeve is arranged on a part, corresponding to the hollow cylinder, outside the cylinder on each water outlet zone in a sleeve manner; the two water outlet zones are located in two zones with different pitches of the screw conveyer.
Description
Technical field
The utility model relates to a kind of folded spiral shell formula sludge dewatering equipment.
Background technology
State, need to dewater to raw material in process of production, existing water extracter: thin thickness, yielding, cause dehydrating effect bad, the moisture percentage in sewage sludge of pressing unbalanced; When next is dehydration, when the gap requirement that is bound to is very little, back pressure plate often enters folded spiral shell formula sludge dewatering equipment outlet, hinders and folds spiral shell formula sludge dewatering equipment internal operation.
Summary of the invention
The utility model, for above weak point, provides a kind of folded spiral shell formula sludge dewatering equipment, and this device can high-efficiency dehydration and had advantages of long service life.
The utility model solves the technical scheme that its technical problem adopts:
A folded spiral shell formula sludge dewatering equipment, comprises hollow cylinder, is provided with rotation axis in cylindrical shell, and rotation axis drives auger; One side upper end of cylindrical shell is provided with import, and the other end is provided with back pressure plate; Auger is divided into two portions, and the pitch of two portions auger is different, wherein, larger near one end pitch of import, less near one end pitch of back pressure plate; The outside of cylindrical shell is provided with two outlet areas, and the radial direction along cylindrical shell on each outlet area is provided with a plurality of posticums, and each outlet area upper shell is outer is arranged with a sliding sleeve with hollow cylinder is corresponding outward; Two different pitch regions of the auger that two outlet areas are positioned at.
Further, described back pressure plate screw thread is fixed on screw shaft, back pressure plate outside be provided with stiffening web, described stiffening web is along the radial direction of back pressure plate, and arranges along the axle center annular array of screw shaft.
The beneficial effects of the utility model are:
The cylindrical shell that the utility model is provided with, as the chamber of accommodating belt sewage sludge, is provided with auger in cylindrical shell, forms the power of dehydration by the screw extrusion of auger.
By the pitch of auger separately, small one and large one, wherein small portion is positioned at the afterbody of cavity, and like this, effectively dewater to the water-containing sludge in cavity in front portion, and little in afterbody pitch, overstocked power is more powerful, and dehydrating effect is better.
In the outside of cylindrical shell, be provided with dehydration region, the dewatering hole by dehydration region can depart from water, and meanwhile, aft mounted back pressure plate can be realized the shutoff to mud on the one hand, on the other hand back pressure plate is unloaded and mud can be discharged.
The sliding sleeve being provided with can be removed the mud of extruding in dewatering hole, prevents shutoff.In back pressure plate end, strengthen, the stiffening web of setting can effectively be placed its distortion.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, the accompanying drawing the following describes is only some embodiment that record in the application, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing;
Fig. 1 is connection diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
In order to make those skilled in the art person understand better the technical scheme in the application, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only the application's part embodiment, rather than whole embodiment.Embodiment based in the application, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the application's protection.
Shown in Fig. 1, a kind of folded spiral shell formula sludge dewatering equipment, comprises hollow cylinder 1, in cylindrical shell 1, is provided with rotation axis, and rotation axis drives auger 2; One side upper end of cylindrical shell 1 is provided with import, and the other end is provided with back pressure plate 3; Auger 2 is divided into two portions, and the pitch of two portions auger is different, wherein, larger near one end pitch of import, less near one end pitch of back pressure plate; The outside of cylindrical shell is provided with two outlet areas, and the radial direction along cylindrical shell on each outlet area is provided with a plurality of posticums 5, and each outlet area upper shell is outer is arranged with a sliding sleeve 4 with hollow cylinder is corresponding outward; Two different pitch regions of the auger that two outlet areas are positioned at.
Described back pressure plate 3 screw threads are fixed on screw shaft, back pressure plate 3 outside be provided with stiffening web, described stiffening web is along the radial direction of back pressure plate, and arranges along the axle center annular array of screw shaft.
Back pressure plate 3 is thick is that 10mm is thick, is slightly larger than folded spiral shell formula sludge dewatering equipment exit diameter, and easy to operate like this, mud extraction water ratio is stable, meets Production requirement.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
