Description

Pneumatic material stirring device

Technical Field

The utility model relates to the field of stirring devices, in particular to a pneumatic material stirring device.

Background

The existing material (powder particle) stirring device is basically composed of a driving motor, a mechanical stirring executing mechanism (such as a propeller blade type and a rotary straight plate type) and the like, and is widely applied to the industrial fields of powder, slurry, particle products and the like.

Firstly, most of mechanical stirring mechanisms for stirring materials rely on a motor to provide driving force for the stirring mechanism, and for the production process of hydrogen storage materials, the electric part in the motor can generate explosion risk to active metal dust;

secondly, for the solid-state hydrogen storage industry, the produced hydrogen storage material needs to be in full and uniform contact with oxygen in the air in a short time, and a layer of passive film is quickly formed, so that the hydrogen storage material cannot be slowly and uniformly oxidized in the transportation and filling processes, and the compactness and uniformity of the material are damaged, therefore, the passive film is quickly formed, so that the hydrogen absorption and release performance of the material at the later stage can be effectively improved, but the common stirring kettle structure is of a sealing cover type or a semi-sealing cover type, so that the internal material cannot be in full contact with the oxygen in the air in a short time;

thirdly, because of too many motor gear drive parts in traditional electric drive agitating unit, will make the material degree of wear of driving medium itself increase day by day, lead to the cost and the depreciation rate of stirred tank equipment dismouting maintenance also to increase correspondingly.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a pneumatic material stirring device, which comprises:

the top concave plate, the rotating finned tube, the main body housing, the gas transmission pipe, the bearing housing and the bearing;

the top concave plate and the main body housing are welded in a full-welding mode;

the main body housing is cylindrical; the rotating finned tubes are uniformly welded on the outer surface of the main body housing;

the joint of the bearing housing and the main body housing adopts a ring welding fixed connection mode;

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1-3, fig. 1-3 are respectively a cross-sectional view, a top view and a perspective view of the present invention; a pneumatic material mixing device, comprising:

the device comprises a top concave plate 1, a rotary finned tube 2, a main body housing 3, a gas pipe 4, a bearing housing 5 and a bearing 6.

The main body housing 3 is cylindrical; the rotary finned tubes 2 are uniformly welded on the outer surface of the main body housing 3;

one end of the gas pipe 4 extends into a dense hole in the housing consisting of the top concave plate 1 and the main body housing 3, and the other end is connected with an air compressor through a gas supply hose.

In this example, an air supply hose (not shown in fig. 1-3) connected to the air supply pipe 4 at the rear is connected to the output port of the air compressor.

An air compressor (not shown in figures 1-3) passes the desired constant pressure gas through a delivery hose (not shown in figures 1-3),

the gas is supplied to the gas pipe 4 and is sprayed into the cavity from the dense hole of the gas pipe 4 which penetrates into the inner part of the cover (consisting of the top concave plate 1 and the main body cover 3). The joint of the top concave plate 1 and the main body housing 3 adopts a full-length welding mode, so that the sealing performance is ensured.

The sprayed gas pressure is utilized to reversely push the rotating finned tube 2 to rotate along a specific direction, and by the mode, the materials can be fully, uniformly and rapidly contacted with the charged air while the materials are stirred by utilizing the length of the rotating finned tube 2, so that a passivation film is generated.

Wherein, the inner ring of the bearing 6, the outer pipe wall of the gas pipe 4 and the inner pipe wall of the bearing housing 5 all adopt a standard bearing assembly mode; the joint of the bearing housing 5 and the main body housing 3 adopts a ring welding fixed connection mode; the wear-resistant sealing ring 7 (such as a fluorine rubber sealing ring and the like) is arranged between the outer pipe wall of the gas pipe 4 and the main body housing 3, so that the sealing performance of the housing can be ensured to a certain extent on the premise that the outer pipe wall of the gas pipe 4 and the main body housing 3 can rotate relatively.

The key points of the implementation of the utility model are as follows:

1. the air flow in the pipeline is used for driving the rotating body to rotate, so that the stirring function can be exerted, the hydrogen storage material and air can be quickly oxidized, and a passivation film is formed;

2. no electric related device is arranged in the structure of the stirring kettle body, so that risks such as explosion caused by electric reasons can be avoided;

3. the air supply device (air compressor) can be placed at will, and the space problem of power equipment such as a drive and the like arranged outside the stirring kettle does not need to be additionally considered.
