Abstract
The utility model relates to a screw shaft, in particular to a novel screw shaft suitable for a screw squeezing sludge dewatering machine. The screw shaft is a ladder-shaped screw shaft (1), screw vanes (2) are arranged on the ladder-shaped screw shaft (1) and are divided into a front concentration section (3) and a back dewatering section (4), and distance between the screw vanes (2) of the front concentration section (3) is larger than that between the screw vanes (2) of the back dewatering section (4). The novel screw shaft has the advantages that the screw shaft is the ladder-shaped screw shaft and is capable of achieving double squeezing due to the ladder shape compared with the screw shaft in the prior art. Further, sludge to be squeezed changes into slices from blocks, so that sewage can be more easily squeezed out, and dewatering effect is improved.
Description
Technical field
The utility model relates to a kind of screw shaft, a kind of more precisely novel screw shaft that is applicable to the screw press sludge dewatering equipment.
Background technology
WWT is the important part of environmental protection industry (epi); Sludge dewatering is again the important step in the WWT; Screw shaft is again the center of sludge dewatering equipment, and the structure of general screw shaft is that spacing of fins is dwindled from big to small gradually, dwindles overstocked space gradually; Increase squeezing effect, the spiral hub diameter of axle is constant.This kind structure makes and is extruded to such an extent that mud is always block, makes that the inner part of mud can not be pushed fully, thereby does not reach better dehydrating effect.
The utility model content
The purpose of the utility model is to overcome above-mentioned weak point, and a kind of novel screw shaft that is applicable to the screw press sludge dewatering equipment is provided.
The utility model is for achieving the above object; The technical scheme that is adopted is: a kind of novel screw shaft that is applicable to the screw press sludge dewatering equipment; It is a trapezoid spiral axle; Said trapezoid spiral axle is provided with screw-blade, and is divided into anterior enriching section and rear portion dewatering period, and the screw-blade gap ratio rear portion dewatering period screw-blade spacing of said anterior enriching section is big.
The beneficial effect of the utility model is: a kind of novel screw shaft that is applicable to the screw press sludge dewatering equipment that is proposed; It is a trapezoid spiral axle, compares with original screw shaft, owing to be trapezoidal shape; So can realize dual extruding; And be extruded mud and become sheet, make sewage more be prone to be extruded, increased the effect of dehydration by bulk.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to set forth;
Fig. 1 is the structural representation of the utility model;
1. screw shaft, 2. screw-blades, 3. anterior enriching section 4. rear portion dewatering periods among the figure.
Embodiment
A kind of novel screw shaft that is applicable to the screw press sludge dewatering equipment as shown in Figure 1; It is a trapezoid spiral axle 1; Said trapezoid spiral axle 1 is provided with screw-blade 2; And be divided into anterior enriching section 3 and rear portion dewatering period 4, screw-blade 2 gap ratio rear portion dewatering periods 4 screw-blades 2 spacings of said anterior enriching section 3 are big.
The workflow of the utility model is following: mud is transported to sludge outlet by screw shaft 1, near screw-blade 2 pitch smaller sludge outlet through screw shaft 1 time; Simultaneously; It is big that the diameter of axle of screw shaft 1 hub becomes, and makes mud become sheet structure by lumphy structure, receives bigger squeeze; Increase squish area, squeeze out more juicy.
Claims (2)
1. novel screw shaft that is applicable to the screw press sludge dewatering equipment, it is a trapezoid spiral axle (1), it is characterized in that; Said trapezoid spiral axle (1) is provided with screw-blade (2), and is divided into anterior enriching section (3) and rear portion dewatering period (4).
2. by the described a kind of novel screw shaft that is applicable to the screw press sludge dewatering equipment of claim 1, it is characterized in that; Screw-blade (2) gap ratio rear portion dewatering period (4) screw-blade (2) spacing of said anterior enriching section (3) is big.
