Description

Air charging device of leaching and stirring equipment

Technical Field

The utility model relates to a technical field of auxiliary device is aerifyd in the stirring, especially relates to a leach agitated vessel aerating device.

Background

As is known, leaching and stirring equipment is the main equipment used in gold ore dressing process. Along with the improvement of the process in recent years, more and more process flows need to be charged with air so as to increase the oxygen enrichment of ore pulp and improve the leaching rate of gold ores. In addition, the stirring efficiency is greatly improved by the air filling, so that the actual power consumption is reduced, most of the existing leaching and stirring equipment adopts a peripheral air filling system, namely, a ring pipe is coiled on the upper edge of the tank body, a plurality of downward pipes are led out and extend to the bottom of the tank body along the inner wall of the tank body, the installation is quite complicated, the maintenance is inconvenient, the existing stirring equipment adopts a central shaft type stirring system mostly, the air filling mode is easy to cause uneven air dispersion, and after the air is stopped, the bottom of the existing stirring equipment does not have a non-return device, so that the ore pulp is sucked backwards to block an air filling pipeline.

SUMMERY OF THE UTILITY MODEL

For solving the technical problem, the utility model provides a can improve the air charging degree of consistency, it is convenient to install, need not complicated pipe arrangement to can reduce leaching agitated vessel aerating device of ore pulp suck-back.

The utility model discloses a leach agitated vessel aerating device, including intake pipe, rotating shaft valve, middle seal assembly, quill shaft and contrary air disperser that ends, rotating shaft valve top and intake pipe intercommunication to rotating shaft valve below and quill shaft threaded connection, rotating shaft valve mid-mounting deep groove ball bearing, the rotating shaft valve is equipped with middle seal assembly with quill shaft cooperation department, quill shaft bottom and contrary air disperser intercommunication that ends.

The utility model discloses a leach agitated vessel aerating device, middle seal assembly includes depression bar and rubber seal pad.

The utility model discloses a leach agitated vessel aerating device, be equipped with item requirement or stainless steel hollow ball in the contrary air disperser that ends.

Compared with the prior art, the beneficial effects of the utility model are that: this use is novel to take the center pin mode of inflating, and it is convenient to take over, and it is convenient to install, need not complicated piping arrangement. The air outlet is arranged at the bottom of the ore pulp and is rotationally pushed by the bottom of the propeller type impeller, so that air is uniformly dispersed, and the air charging uniformity is improved. The bottom of the main shaft is provided with a non-return air disperser, so that the ore pulp can be prevented from being sucked backwards after the aeration is stopped while the air at the bottom is dispersed uniformly. Simple structure and convenient maintenance. No more complex piping needs to be provided. Greatly saves the pipe distribution material and simplifies the process. The hollow shaft adopts a thick-wall pipe structure, so that the material taking is simple, and the compact sealing structure ensures that gas does not leak.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

in the drawings, the reference numbers: 1. a rotary shaft valve; 2. a middle seal assembly; 3. a hollow shaft; 4. a non-return air disperser.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in figure 1, the aerating device of the leaching and stirring equipment of the utility model consists of a main shaft upper end rotating shaft valve (1), a hollow shaft (3), a middle sealing component (2) and a bottom non-return air disperser (4). The upper part of the rotary shaft valve (1) is connected with an air inlet pipe, and only one air inlet pipe is connected. The lower part is connected with the hollow shaft (3) by screw thread. The middle part is provided with the deep groove ball bearing, the lower main shaft can freely rotate due to a split structure, the upper air inlet pipe cannot be driven, and the deep groove ball bearing is matched with a pressing type oil cup, so that the lubrication is convenient and fast. The joint of the rotary shaft valve (1) and the hollow shaft (3) is provided with a middle sealing component (2) which comprises a gland and a rubber sealing gasket, and the compaction is tight without air leakage. Air is introduced into the hollow shaft (3) through the rotary shaft valve (1), and the air disperser (4) is in a non-return state along the bottom of the shaft end, and the inner sleeve of the non-return air disperser (4) is in a horn mouth shape and is filled with a rubber ball or a stainless steel hollow ball with lighter weight. The balls are pushed open by the air pressure, so that the air is dispersed in the medium in the groove. After the air is stopped, the ball floats upwards by the buoyancy of the ore pulp to block the bell mouth, so that the reverse suction of the ore pulp is prevented.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
