Abstract
The utility model discloses a defeated mud machine spiral shaft sealing mechanism of auger, this defeated mud machine spiral shaft sealing mechanism of auger is equipped with packing cavity and sealing gland, characterized by including setting up the seal receptacle on the casing end plate in the seal receptacle: be equipped with K shape polyurethane deflector in the packing cavity, K shape polyurethane deflector includes the cylinder base member, is equipped with a plurality of fenders sand bulge loops along the axial on the inner circumference of cylinder base member, be equipped with 3 at the inner circumference of cylinder base member at least along the axial and keep off the sand bulge loops, keeping off the sand bulge loop and keeping off the sand bulge loop for the trapezoid cross section, this defeated mud machine spiral shaft sealing mechanism of auger can prevent granule impurity to follow the sealed chamber of axial seal clearance entering and lead to seal failure, and is sealed effectual, long service life, installation and maintenance convenience.
Description
Technical field
This utility model relates to a kind of shaft sealer, especially a kind of helical axis sealing device for auger slurry conveying machine。
Background technology
Auger slurry conveying machine is typically mounted on bottom the inclined-plate clarifying basin of sludge treatment device, the many employings of helical axis sealing device of auger slurry conveying machine of the prior art are at static seal gland and rotate the packing seal mode of filling packing between axle, work one section time after, a small amount of sand can invade packing cavity along helical axis seal clearance, making packing and " sand " come in mutually rub, packing is quickly worn away a lot, causes seal failure, accordingly, it would be desirable to regular replacing or supplementary packing。
Utility model content
Utility model to solve the technical problem that: provides a kind of auger slurry conveying machine helical axis sealing device, this auger slurry conveying machine helical axis sealing device can stop granule foreign seal clearance vertically to enter annular seal space and cause seal failure, good sealing effect, long service life, install and easy to maintenance。
Solve the technical scheme that technical problem is taked: a kind of auger slurry conveying machine helical axis sealing device, including the seal receptacle being arranged on housing end plate, packing cavity and sealing gland it is provided with in seal receptacle, K shape polyurethane sand retaining ring it is provided with in packing cavity, described K shape polyurethane sand retaining ring includes cylindrical base, is provided with multiple sand block bulge loop on the inner peripheral surface of cylindrical base vertically。
As improvement of the present utility model: at the inner peripheral surface of cylindrical base vertically at least provided with 3 road sand block bulge loops。
As improvement of the present utility model: described sand block bulge loop is trapezoid cross section sand block bulge loop。
Beneficial effect: auger slurry conveying machine helical axis sealing device of the present utility model, owing to have employed the seal receptacle that described auger slurry conveying machine helical axis sealing device includes being arranged on housing end plate, packing cavity and sealing gland it is provided with in seal receptacle, K shape polyurethane sand retaining ring it is provided with in packing cavity, described K shape polyurethane sand retaining ring includes cylindrical base, the inner peripheral surface of cylindrical base is provided with the technical characteristic of multiple sand block bulge loop vertically, it is filled in packing cavity by substituting packing filling of the prior art with K shape polyurethane sand retaining ring, under the effect of sealing gland, the sand block bulge loop of sand retaining ring can closely cooperate with helical axis, granule foreign seal clearance vertically is stoped to enter annular seal space, and, even if also can accumulate between sand block bulge loop after having a small amount of granule foreign to enter into annular seal space, helical axis and sand retaining ring will not be caused serious abrasion, therefore, this utility model has good sealing effect, the advantages such as long service life, in addition, owing to adopting integrally-built K shape polyurethane sand retaining ring to substitute packing filling, make the installation of sealing device and safeguard more convenient, laborsaving。Owing to reasonably defining the number of the inner peripheral surface sand block bulge loop of cylindrical base, further increase sand block effect and the sealing effectiveness of auger slurry conveying machine helical axis sealing device。Owing to have employed the technical characteristic that described sand block bulge loop is trapezoid cross section sand block bulge loop, add the strength and stability of sand block bulge loop, the frictional resistance of helical axis has been taken into account while improving sealing, sand block effect, and, achieve the abrasion being compensated sand block bulge loop by compression seal gland, further increase the service life of auger slurry conveying machine helical axis sealing device of the present utility model。Auger slurry conveying machine helical axis sealing device helical axis of the present utility model rotates freely, and overcomes packing_seal of the prior art and easily occurs that " card sand " causes the defect of seal failure。
Accompanying drawing explanation
Below in conjunction with accompanying drawing, auger slurry conveying machine helical axis sealing device of the present utility model is described in further detail。
Fig. 1 is the structural representation of auger slurry conveying machine helical axis sealing device of the present utility model。
Detailed description of the invention
As shown in Figure 1, auger slurry conveying machine helical axis sealing device of the present utility model includes the seal receptacle 2 being arranged on housing end plate 1, packing cavity 4 and sealing gland 6 it is provided with in seal receptacle, K shape polyurethane sand retaining ring 5 it is provided with in packing cavity, described K shape polyurethane sand retaining ring includes cylindrical base 51, the diameter of cylindrical base is less than packing cavity diameter 0.1 1 millimeters, the width of cylindrical base is identical with the filling width of packing filling, the inner peripheral surface of cylindrical base is provided with multiple sand block bulge loop 52 vertically, the internal diameter of sand block bulge loop coordinates with helical axis 3 sealing, in order to ensure sealing effectiveness, preferably in the inner peripheral surface of K shape polyurethane sand retaining ring cylindrical base vertically at least provided with 3 road sand block bulge loops, described sand block bulge loop is preferably trapezoid cross section sand block bulge loop。
In auger slurry conveying machine helical axis sealing device of the present utility model, K shape polyurethane sand retaining ring can also adopt other nonmetallic materials with certain elasticity and self-lubricating property to make。
