Abstract
The utility model discloses a screw is used in connection of pressure filter cassette, including screw head and screw pole, be equipped with the screwing hole that evenly arranges along the screw head edge more than two on the screw head top surface. The utility model discloses in establish the hole of screwing up more than two at screw head edge, insert with specialized tool when screwing up and screw up downthehole can the rotating, owing to screw up the edge of hole dispersion distribution at the screw head, the fluting area is dispersed and is difficult to form the pressure line, difficult fracture.
Description
Technical Field
The utility model relates to a pressure filter field especially relates to a screw is used in connection of pressure filter cassette.
Background
Traditional filter and pressure filter organism are integrative, can not bear the superhigh pressure, and easy loss simultaneously, and damage back maintenance process is complicated, maintenance cycle length, influences complete machine working effect. At present, use the screw to fix the cassette on the filter plate, be convenient for installation and maintenance, in order to reduce the damage of filter cloth, the screw can not bulge the filter, but does not bulge the filter, just must slot or trompil on the screw head, but traditional screw tightening hole generally is the plum blossom groove or the straight line groove that are located the center, the plum blossom hole is concentrated in screw head center and fluting area big, can split during the high pressure, a straight line hole forms the pressure line easily, also can split during the high pressure, so work under present screw can't satisfy super high pressure.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a screw is used in connection of pressure filter cassette.
The utility model discloses an innovation point lies in the utility model discloses in establish the hole of screwing up more than two at screw head edge, insert with specialized tool when screwing up and screw up downthehole can the rotating, owing to screw up the edge of hole dispersion distribution at the screw head, the fluting area is scattered and is difficult to form the pressure line, difficult fracture.
In order to realize the purpose of the utility model, the technical proposal of the utility model is that:
the utility model provides a screw is used in connection of pressure filter cassette, includes screw head and lead screw, be equipped with the tightening hole that evenly arranges along the screw head edge more than two on the screw head top surface.
Further, there are 4 of the tightening holes. The operation is easier when screwing the screw.
Further, the tightening hole is a through hole. The positions of the bolt holes on the filter plate can also be pervious to water, and the humidity of the pressed mud cakes is uniform.
Further, the bottom of the tightening hole is conical. The flow guide effect is better.
Further, the bottom of the screwing hole is tightly attached to the edge of the lead screw. The production is good, and the reference flour is available; when the bottom of the screwing hole is tightly attached to the edge of the screw rod, the screw rod can play a part of supporting role, and the bearing capacity is better; the water pressed through the screwing hole flows along the guide rod, so that the guide effect is better.
Further, the screw head and the screw rod are made of metal. The bearing capacity is stronger.
Furthermore, the diameter of the tightening hole is less than or equal to 5mm. The filter cloth can not be damaged due to repeated squeezing in the hole under ultrahigh pressure.
The utility model has the advantages that:
1. the utility model discloses in establish the hole of screwing up more than two at the screw head edge, insert to screw up downthehole can the rotating with specialized tool when screwing up, owing to screw up the hole and distribute at the edge of screw head, the fluting area is scattered and is difficult to form the pressure line, difficult fracture.
2. The utility model provides a screw up the hole and both can be used as screwing up, can be used as permeating water again, a hole is dual-purpose for the mud biscuit humidity that the suppression was come out is even.
