Abstract
The utility model discloses an improved combined spherical corundum porous aerator. The improved combined spherical corundum porous aerator comprises an aeration head, a ventilation screw rod, a connection block and a ventilation branch pipe, wherein the aeration head is formed by fixedly mounting an upper shell and a lower shell through butting, and an air chamber is formed in the aeration head; middle through type mounting holes are formed in middle-axis portions of the upper and lower shells of the aeration head, and the ventilation screw rod extends in the mounting hole from bottom to top; the mounting hole of the upper shell is circular, and the mounting hole of the lower shell is square; the cross section of the portion, corresponding to the mounting hole of the upper shell, of the ventilation screw rod is circular, and the cross section of the portion, corresponding to the mounting hole of the lower shell, of the ventilation screw rod is square. According to the improved combined spherical corundum porous aerator, the original circular structures of the mounting holes and the screw rod are changed, the tightness between the screw rod and mounting holes of the aerator is good after change, loosening, rotating and falling-off are not easily caused during operation, the friction between the screw rod and the mounting holes is low after change, and the wear and tear between the screw rod and the mounting holes are reduced, so that the cost is reduced.
Description
Technical field
The utility model belongs to sewage treatment area, is specifically related to a kind of modified version combination ball-type corundum micropore aerator.
Background technology
Existing GYQ type ball-type corundum micropore aerator is all made up of housing, screw rod, pad, nut, the shortcoming existing is that pilot hole, the screw rod of housing is all round up and down, cause easily loosening rotation in the time of operation, cause screw rod wearing and tearing fracture and come off, affect the normal operation of sewage disposal.
Utility model content
It is good that the purpose of this utility model is to provide tightness between a kind of screw rod and hole, is difficult for becoming flexible, rotating, come off when operation, reduced wearing and tearing, reduced the modified version combination ball-type corundum micropore aerator of cost.
A kind of modified version combination ball-type corundum micropore aerator described in the utility model, comprises aeration head, ventilation screw rod, contiguous block, ventilation arm, nut and backstop mother; Described aeration head is fixedly mounted with and is formed by upper housing, lower housing make-up, forms air cavity in it; Be provided with the pilot hole of formula of along the upper housing of aeration head, the axis position of lower housing, ventilation screw rod stretches in pilot hole from below to up, and is connected with air cavity; Ventilation screw rod upper end is fixed on aeration head by nut, and lower end is fixed on aeration head by backstop mother, and the ventilation screw rod at lower housing axis position is connected with ventilation arm by contiguous block; Pilot hole on described upper housing is circular, and the pilot hole on lower housing is square; The cross section at the position of matching with the pilot hole on upper housing on ventilation screw rod is for circular, and the cross section at the position of matching with the pilot hole on lower housing is square.
Further improve, between described nut and the upper housing of aeration head, be provided with seal washer.
Further improve, between the lower housing of described aeration head and backstop mother, be provided with seal washer.
Further improve, described aeration head is that emergy is fired the ceramic body forming.
Further improve, described nut is single nut or double nut.
Further improve, described seal washer is butyronitrile rubber.
The beneficial effects of the utility model are:
Compared with prior art, change the circular configuration of original pilot hole and screw rod, tightness between screw rod and the hole of the aerator after improvement is better, when operation, be difficult for becoming flexible, rotate, come off, the friction between screw rod and hole after improvement has reduced, wearing and tearing are between the two reduced, thereby reduced cost, while also having solved operation, screw rod wearing and tearing fracture and come off, and affect the problem of the normal operation of sewage disposal.
