Description

Technical Field

[0001] The utility model relates to the technical field of ore mining, in particular to an axial flow fan used in mines. Background Art

[0002] In the process of mining ore, the mine needs to use fans to transport air into the mine to provide sufficient oxygen in the mine. The flow of air in the mine needs to be carried out in multiple stages, mainly through axial flow fans for segmented drainage;

[0003] For example, patent application number CN202321242486.0 discloses a coal mine ventilation volume detection device, which uses an axial flow fan for ventilation. The wind-bearing plate moves under the impetus of the airflow, and the wind pressure is obtained by detecting the real-time pressure on the wind-bearing plate to convert it into ventilation volume. The wind-bearing plate is vertically arranged along the height direction of the ventilation lane, which expands the wind collection surface and improves the detection reliability. The pressure detection component is fixed in the detection shell to avoid contamination or damage. The measurement result should be improved, thereby improving the accuracy of ventilation volume detection;

[0004] During use, the axial flow fan in the prior art filters the air through a filter assembly, but the existing filter assembly lacks a dehumidification function. In order to reduce the dust generated by blasting in the mine, dust reduction is carried out through spraying, which causes a large amount of moisture to enter the axial flow fan, affecting the service life of the axial flow fan.

[0011] A driven roller is rotatably disposed in the box body;

[0012] The filter screen is annular, with one end sleeved on the driving roller and the other end sleeved on the driven roller;

[0013] A plurality of first mesh covers, the opening ends of which are fixedly connected to the inner wall of the filter screen on one side close to the air inlet;

[0014] A plurality of second mesh covers, the opening ends of which are fixedly connected to the inner wall of the filter screen on one side close to the air outlet;

[0015] The filter screen is used to drive the first mesh cover to move to a position facing the air inlet, or to drive the second mesh cover to move to a position facing the air outlet.

[0016] Preferably: the side wall of the box body is provided with a door panel, and the door panel has a grip panel.

[0017] Preferably: a dust cover is arranged on the side wall of the box body corresponding to the side of the door panel.

[0018] The beneficial effects of adopting the above technical solution are:

[0019] The present application can filter the air entering the box body through the filter screen, and desiccant can be placed in the first mesh cover and the second mesh cover to achieve dehumidification. The box body can be opened by the door panel to replace the desiccant in the first mesh cover and the second mesh cover, and the first mesh cover and the second mesh cover can dehumidify the air in turn.

DETAILED DESCRIPTION

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-3 In the first embodiment, an axial flow fan for a mine includes:

[0026] The fan box 20 is fixedly connected to the mounting plate 10 and has a plurality of mounting chambers;

[0027] A plurality of axial flow fans 30 are respectively arranged in the installation room;

[0028] The box body 40 is fixedly connected to the mounting plate 10. The box body 40 has an air outlet 42 at a position corresponding to the mounting chamber, and the side wall of the box body 40 has an air inlet 41 on the side wall corresponding to the air outlet 42.

[0029] A driving roller 51 is rotatably disposed in the box body 40;

[0030] A driven roller 52 is rotatably disposed in the box body 40;

[0031] The filter screen 50 is annular, one end of which is sleeved on the driving roller 51 and the other end of which is sleeved on the driven roller 52;

[0032] A plurality of first mesh covers 60, the opening ends of which are fixedly connected to the inner wall of the filter screen 50 near the air inlet 41;

[0033] A plurality of second mesh covers 70, the opening ends of which are fixedly connected to the inner wall of the filter screen 50 near the air outlet 42;

[0034] The filter screen 50 is used to drive the first mesh cover 60 to move to a position facing the air inlet 41 , or to drive the second mesh cover 70 to move to a position facing the air outlet 41 .

[0035] This embodiment is implemented as follows:

[0036] When the present application is in use, the filter 50 is first driven to rotate by rotating the driving roller 51, so that the first mesh cover 60 on the filter 50 moves to the position of the air inlet 41, so that the desiccant placed in the first mesh cover 60 can dehumidify the air entering the box body 40. After the desiccant in the first mesh cover 60 has been dehumidified for a period of time, the filter 50 is rotated again, so that the desiccant in the second mesh cover 70 moves to a position facing the air outlet 42, and is dried by the desiccant in the second mesh cover 70, while the first mesh cover 60 leaves the position of the air inlet 41, and the desiccant is replaced.

[0037] Compared with the prior art, the present application has the advantage that the air passing through the axial flow fan can be dried.

[0038] See also Figure 1 The side wall of the box body 40 is provided with a door panel 43, and the door panel 43 has a grip panel 44;

[0039] The door panel 43 can be rotated and opened by the grip plate 44 disposed on the door panel 43, so that the desiccant can be put into the first mesh cover 60 or the second mesh cover 70 or taken out.

[0040] See also Figure 1 A dust cover 80 is provided on the side wall of the box body 40 corresponding to the door panel 43;

[0041] The dust hood 80 enables a worker to suck away dust in the box body 40 when cleaning the filter 50 with a brush.

[0042] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
