Abstract
The invention discloses a sludge dewatering machine threaded rod with the outer contour radial size capable of being fine adjusted. The sludge dewatering machine threaded rod comprises an anti-abrasion strip and a gasket which are connected with each other by bolts along the outer contour of a screw panel of the threaded rod. The anti-abrasion strip is a rectangular strip block, and at least two counter bores for radial installation of the bolts are arranged on the centerline of the rectangular strip block in the length direction. The outer contour of the screw panel of the threaded rod is provided with a preset circular bead, the circular bead is provided with radial screw holes matched with the anti-abrasion strip, the gasket is arranged between the anti-abrasion strip and the circular bead and is tightly locked by the blots, and the thickness of the gasket is used for compensating the installation dimension of the anti-abrasion strip in the radial direction. Replacement of gaskets with different thicknesses and a detachable structure are used for compensating the abrasion loss of the anti-abrasion strip; and the structure is convenient to maintain, can prevent the abraded threaded rod from being integrally scraped, and saves the using cost.
Description
Technical field
The present invention relates to a kind of screw-rod structure of sludge pressing water extracter, specifically, the present invention relates to the fine-tuning sludge dewatering equipment screw rod of a kind of radial dimension.
Background technology
The main movement part of spiral sludge pressing water extracter is screw rod, there are tolerance clearance and relative movement between the screw rod of rotation and static cartridge filter inwall, produce inner high voltage in expressing process and impel wet mud to bleed among tolerance clearance with the water squeezed out, form the pair of friction components with grinding condition during relative movement.Long term wear strengthens the tolerance clearance of screw rod and cartridge filter, further worsens the press dewatering condition, directly reduces sludge pressing effect and production efficiency.The screw rod of prior art is one-piece construction, and this kind of large-scale spiral shaft component is too large because of the overproof scrap cost of wearing and tearing, and reparation is difficult to and is long in time limit, seriously restricts spiral sludge pressing water extracter production efficiency.
Summary of the invention
The present invention, mainly for the deficiency of existing technology, proposes the fine-tuning sludge dewatering equipment screw rod of a kind of outline radial dimension, and this screw rod radially fine tuning structure is simple, installs reliably, and it is easy, accurate to regulate, and running cost is cheap.
The present invention is achieved through the following technical solutions technical object.
The sludge dewatering equipment screw rod that the outline radial dimension is fine-tuning, it comprises along screw spiral sheet bolted chafing strip and pad for outline.Its improvements are: described chafing strip is the rectangle stick, is provided with at least 2 counterbores of radially installing for bolt on the length direction center line.The flight outline of described screw rod is provided with preset shoulder, and shoulder is provided with the radially screw matched with chafing strip, and pad is placed between chafing strip and shoulder and is tightened by bolts, and forms the abrasion loss of carrying out the radial compensation chafing strip with the thickness of pad.
The die casting that chafing strip in said structure is the Wimet material, have stronger wear resistance, after wearing and tearing, can adjust tolerance clearance by adjusting spacer thickness, and overwear vt. is detachably changed.
The present invention compared with prior art, has following positively effect:
1, the flight outline chafing strip of splicing is simple in structure, connects reliable;
2, can realize the fine setting compensation by increasing pad after the chafing strip gauge wear, eliminate radius clearance easy and simple to handle, province consuming time;
3, can regulate, demountable structure, easy to maintenance, avoid the screw rod integral body after wearing and tearing to scrap, save use cost.
The accompanying drawing explanation
Fig. 1 is the single flight coaxial direction of the present invention cross section structure schematic diagram.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.
The fine-tuning sludge dewatering equipment screw rod of flight outline radial dimension shown in Fig. 1, it comprises chafing strip 3 and the pad 2 connected with bolt 4 along screw rod 1 flight outline.Described chafing strip 3 is the rectangle stick, is provided with at least 2 counterbores of radially installing for bolt on the length direction center line, the die casting that the present embodiment chafing strip 3 is the Wimet material, uniform 3 counterbores on every chafing strip 3.The flight outline of screw rod 1 is provided with preset shoulder, and shoulder is provided with the radially screw matched with chafing strip 3, and pad 2 is placed between chafing strip 3 and shoulder and, with bolt 4 lockings, forms the abrasion loss of carrying out radial compensation chafing strip 3 with the thickness of pad 2.Its reduced thickness after chafing strip 3 wearing and tearing, form screw rod 1 and increase with the tolerance clearance of cartridge filter, reduced sludge pressing efficiency and quality.Adopt device just of the present invention to make shutdown maintenance, concrete operations are to screw off bolt 4, take out chafing strip 3 and pad 2, reselect the thickness of pad 2 according to abrasion loss, compensate the radial wear of chafing strip 3 with the thickness difference of pad.This kind can adjusting, demountable structure, easy to maintenance, avoids screw rod 3 integral body after wearing and tearing to scrap, and greatly saves use cost.
