Description

A kind of oxidation trough shaft mounting structure

Technical field

This utility model relates to mineral resources ore dressing field, specifically a kind of oxidation trough stirring Axle mounting structure.

Background technology

In mineral resources ore dressing field, often use various agitator tank, such as in microorganism The oxidation trough used in extraction of gold process, and shaft is the important component part of various groove.Such as figure Shown in 1, shaft overall structure of the prior art mainly includes motor, reductor, support Bearing housing, loading arm, shaft body and stirrer paddle, wherein motor is connected with reductor, The output shaft of reductor is connected with loading arm by shaft coupling, and loading arm passes described spring bearing Being connected with shaft body by flange after casing, blade is arranged on shaft body, this knot The advantage of structure is the gravity suffered by spring bearing casing and shaft body and blade, all by holding Weighing arm undertakes, and thus makes reductor not have gravity load, the service life of prolonged deceleration machine. But when actually used, this kind of structure but exists many defects, firstly because loading arm and stirring The flange that axle body is connected is arranged in cell body and distance oxide ore Starch Level is relatively near, and oxide ore Starch Level always covers the highly acid foam that thick layer is thick, the most just makes described flange be immersed in foam In, the time one is long, and this flange is just damaged by sour corrosion, often overhaul, and in inspection Repairing and the ore pulp in groove is all emptied before, this has had a strong impact on normal production operation, secondly Blade of the prior art generally uses little blade, and rotating speed is higher, on the one hand little not due to blade The concentrate that can make bottom aggradation all stirs and hangs, the most again owing to using high rotating speed, oar The shearing force that leaf produces in high rotating speed is relatively big, and the damage so caused oxidizing bacteria is relatively big, It is unfavorable for that oxidation index meets requirement.

Utility model content

The purpose of this utility model is to provide a kind of oxidation trough shaft mounting structure, uses straight Connect hang and shaft body be installed, change little blade into big blade simultaneously and reduce rotating speed, Improve the running efficiency of equipment, thus improve yield, and structure is the compactest.

The purpose of this utility model is achieved through the following technical solutions:

A kind of oxidation trough shaft mounting structure, including driving means, crossbeam, shaft body And blade, its middle cross beam is arranged at one end of cell body, is provided with base on described crossbeam, described Driving means is arranged on described base, and shaft body is arranged in cell body and through described horizontal stroke Being connected with described driving means after base on beam, shaft body is driven by described driving means Dynamic rotation, is provided with blade on shaft body.

Described driving means includes that motor and speed reducer, described motor are connected with described reductor, The output shaft of described reductor is connected with described shaft body by shaft coupling.

Described blade width L is equivalent to the 45%～55% of cell body width S, described blade rotating speed It it is 15～22 revs/min.

Advantage of the present utility model with good effect is:

1, this utility model uses direct hang to install shaft body, eliminates support Bearing housing, loading arm and flange, thus avoid the situation of flange corrosion and damage impact production, And structure is the compactest.

2, diameter of propeller blade L that this utility model is used be equivalent to cell body diameter S 45%～ 55%, rotating speed reduces to 15～22 revs/min, and the concentrate that the most just can make bottom aggradation is whole Stirring is hanged, and also extends blade service life.

Accompanying drawing explanation

Fig. 1 is oxidation trough shaft mounting structure schematic diagram of the prior art,

Fig. 2 is this utility model schematic diagram.

Wherein, 1 is motor, and 2 is reductor, and 3 is base, and 4 is shaft coupling, and 5 is crossbeam, 6 is cell body, and 7 is shaft body, and 8 is blade, and 9 is spring bearing casing, and 10 is method Orchid, 11 is loading arm.

Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings.

As in figure 2 it is shown, this utility model includes driving means, crossbeam 5, shaft body 7 With blade 8, its middle cross beam 5 is arranged at one end of cell body 6, is provided with the end on described crossbeam 5 Seat 3, described driving means is arranged on described base 3, and shaft body 7 is arranged at cell body In 6, and one end of described shaft body 7 through after the base 3 on described crossbeam 5 with Described driving means is connected, and shaft body 7 is driven by described driving means and rotates, and is stirring Mix axle body 7 and be provided with blade 8.

As in figure 2 it is shown, described driving means includes motor 1 and reductor 2, described motor 1 Being connected with described reductor 2, the output shaft of described reductor 2 is stirred with described by shaft coupling 4 Mix axle body 7 to be connected.

As in figure 2 it is shown, blade 8 of the present utility model uses the replacement of big blade of the prior art Little blade, blade 8 diameter L of the prior art is only equivalent to the 30% of cell body 6 diameter S, Rotating speed is usually 48 revs/min, and the blade 8 diameter L that this utility model is used is equivalent to The 45%～55% of cell body 6 diameter S, rotating speed reduces to 15～22 revs/min, the most just can The concentrate making bottom aggradation all stirs and hangs, and also extends blade 8 service life.

Operation principle of the present utility model is:

As it is shown in figure 1, shaft mounting structure of the prior art include spring bearing casing 9, Loading arm 11 and flange 10, the output shaft of reductor 2 is by shaft coupling 4 and loading arm 11 Being connected, loading arm 11 passes through flange 10 and shaft body 7 after spring bearing casing 9 Being connected, described flange 10 is easy to by corrosion and damage, as in figure 2 it is shown, this utility model is adopted Use underslung mounting structure, eliminate spring bearing casing 9, loading arm 11 and flange 10, The output shaft of reductor 2 is directly connected with shaft body 7 by shaft coupling 4, oar simultaneously The larger of leaf 8, rotating speed reduces, thus improves the running efficiency of equipment, and structure The compactest.
