Abstract
The utility model discloses a kind of main rake of ore dressing thickener harrow frame, comprise main rake body, described main rake body comprises rake body and rake pawl, described main rake body is that hollow square steel is welded, one end of rake body is connected with rake pawl, and the end opens through hole of the other end, by interior sheathed bearing pin, nylon jacket and the steel bushing successively of putting in place in described through hole, described steel bushing is welded on the end of rake body, and rake body is fixed with hanger.The utility model structure is simple, easy to use, can be more energy-conservation relative to existing main rake, is convenient to cleaning, can reduce wearing and tearing simultaneously, reduces maintenance cost.
Description
Technical field
The utility model relates to a kind of ore dressing thickener, in particular a kind of main rake of ore dressing thickener harrow frame.
Background technology
Thickener is a machine being applicable to the concentrate and tailings processed in ore dressing plant, is widely used in the industries such as metallurgy, chemical industry, coal, nonmetal ore-dressing, environmental protection.
Thickener generally primarily of concentration basin, cake frame, transmission device, cake frame lifting device, charging gear, device for discharging and signals security device thickener operationally, thickener has a dump skip of discharging concentrated product at Chi Di center, commercial port, pond periphery is provided with annular overflow trough, the structure of high-efficiency concentrator is similar to center driving thickener, and high-efficiency concentrator is generally primarily of compositions such as concentration basin, cake frame, transmission device, cake frame lifting device, charging gear, device for discharging and signals security devices.
On thickener, main rake is easy losser, and existing main rake is generally angle steel and is welded, and ore dressing effect is bad.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of main rake of ore dressing thickener harrow frame, improves life-span and the operating efficiency of main rake.
The utility model is achieved through the following technical solutions, the utility model comprises main rake body, described main rake body comprises rake body and rake pawl, described main rake body is that hollow square steel is welded, one end of rake body is connected with rake pawl, and the end opens through hole of the other end, by interior sheathed bearing pin, nylon jacket and the steel bushing successively of putting in place in described through hole, described steel bushing is welded on the end of rake body, and rake body is fixed with hanger.
As one of preferred embodiment of the present utility model, the angle of described rake body and rake pawl is 100 ~ 120 °.
The utility model has the following advantages compared to existing technology: the utility model structure is simple, easy to use, can be more energy-conservation relative to existing main rake, is convenient to cleaning, can reduce wearing and tearing simultaneously, reduces maintenance cost.
Accompanying drawing explanation
Fig. 1 is the new structural representation of this practicality;
Fig. 2 is the partial schematic diagram of rake end of body.
Detailed description of the invention
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As depicted in figs. 1 and 2, the present embodiment comprises main rake body, described main rake body comprises rake body 1 and rake pawl 2, described main rake body is that hollow square steel is welded, one end of rake body 1 is connected with rake pawl 2, the end opens through hole 11 of the other end, by interior sheathed bearing pin 12, nylon jacket 13 and the steel bushing 14 successively of putting in place in described through hole 11, described steel bushing 14 is welded on the end of rake body 1, and rake body 1 is fixed with hanger 15.The angle of rake body 1 and rake pawl 2 is 100 °.
During the present embodiment work, using square steel structure instead is because the relative angle steel of square steel is large to the contact area of ore dressing liquid, is not easy to accumulate on steelframe dirty, and due to hollow structure, liquid has certain buoyancy to main rake entirety, is convenient to overall drive, more energy-conservation.
In original structure, steel bushing 14 and bearing pin 12 easily wear and tear, and get rusty easily, and the cost of replacing is higher, after increasing nylon jacket 13, are not easy to get rusty, improve wearability simultaneously, reduce the maintenance cost of main rake.
