Abstract
The utility model relates to a dehydrator, aiming at the technical problems that an existing dehydrator is low in the yield and quality of material dehydration, and unsatisfactory in the treatment of nonuniform materials, and provides a spiral extrusion type dehydrator with variable-pitch double-spiral blades to solve the problems. The dehydrator comprises a spiral shaft and spiral blades, wherein the spiral blades are arranged on the spiral shaft; the spiral shaft consists of a charging-end spiral shaft, a middle spiral shaft and a discharging-end spiral shaft; the pitch between the spiral blades on the middle spiral shaft is greater than the pitch between the spiral blades on the discharging-end spiral shaft; the spiral blades arranged on the charging-end spiral shaft are double-spiral blades. According to the spiral extrusion type dehydrator, as a charging end is provided with the double-spiral blades, the charging amount within unit time is increased, and the yield is improved; as a discharging end is provided with the variable-pitch blades, the discharging amount within unit time is decreased, and the extrusion dehydration effect is improved.
Description
Technical field
The utility model relates to a kind of dewaterer, is specifically related to the traitorous spiral squeezing type dewaterer of a kind of double helix blade.
Background technology
Existing spiral squeezing type dewaterer is continued to use single-screw blade as advancing and pressurizing unit always, and under identical rotating speed and power situation, inlet amount is less, and the quality of extrusion dehydration is not high yet, and the output to material dewatering and quality are not high.Helical axis is continued to use cylindrical standard shaft always, and the dewaterer extrusion dehydration effect of this kind of structure is not fine, and especially, in the time processing the larger inhomogeneous material of volume, deviation of weight, effect is extremely undesirable.
Summary of the invention
The technical problems to be solved in the utility model be existing dewaterer to material dewatering output and of low quality, undesirable to the treatment effect of heterogeneous material, for addressing the above problem, provide a kind of double helix blade spiral squeezing type dewaterer of switching political loyalty.
The purpose of this utility model realizes in the following manner:
The double helix blade spiral squeezing type dewaterer of switching political loyalty, comprise helical axis and be arranged on the helical blade on helical axis, described helical axis is made up of feed end helical axis, middle spiral axle and discharge end helical axis, and helical blade pitch on middle spiral axle is greater than the helical blade pitch on discharge end helical axis; The helical blade arranging on described feed end helical axis is double helix blade.
The helical blade arranging on described middle spiral axle and discharge end helical axis is single-screw blade.
Described double helix blade pitch is the 1/3-2/3 of single-screw blade pitch on middle spiral axle.
With respect to prior art, the utility model feed end is double helix blade, and in the unit interval, inlet amount increases, and output has improved; Discharge end is the helical blade of switching political loyalty, and in the unit interval, load reduces, extrusion dehydration effect promoting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the double helix blade spiral squeezing type dewaterer of switching political loyalty, comprise helical axis 1 and be arranged on the helical blade 2 on helical axis, helical axis is made up of feed end helical axis 11, middle spiral axle 12 and discharge end helical axis 13, and helical blade pitch b on middle spiral axle is greater than the helical blade pitch c on discharge end helical axis; The helical blade arranging on feed end helical axis is double helix blade 22.The helical blade arranging on middle spiral axle and discharge end helical axis is single-screw blade 21.Double helix blade pitch a is the 1/3-2/3 of single-screw blade pitch b on middle spiral axle.
Helical axis is connected with motor 6 main shafts, material enters from charging aperture 4, under same rotational speed and power situation, in unit interval, inlet amount promotes greatly, inlet amount is large, extrusion dehydration successful to material improves, and the material after extrusion dehydration is discharged from discharging opening 5, and the water that material produces is discharged from the delivery port 3 that is arranged on dewaterer below.The pitch of discharge end helical blade is less than the pitch of helical blade on middle spiral axle, can reduce the load in the unit interval, improves dehydrating effect, and in the time that heterogeneous material is dewatered, dehydrating effect obviously improves especially, has improved the dehydration quality of product.
