Problems solved by technology

[0002] At present, with the development of the mining industry and the extension of the mining depth of the mine, people pay more and more attention to the ventilation problem of the mine. The dust and the dry and high temperature environment under the mine seriously affect the health of the workers and bring great harm to the safety of production. Hidden danger, mine ventilation needs to work all the time, but the long-term working motor will inevitably cause the motor to overheat, which will cause the motor to stop working. If the ventilation device can work intermittently without affecting continuous ventilation, such a device will greatly delay the life of the fan Also does not affect the continuous ventilation of the motor

Embodiment Construction

[0017] According to the attached figure 1 The present invention is described in detail:

[0018] A two-machine alternately working combination type mine ventilation device, which includes a chassis 1, two ventilation systems up and down are arranged inside the chassis 1, a support plate 3 is provided at the bottom of the chassis 1 and a matching support plate Roller 2 is characterized in that:

[0019] The chassis 1 is in the shape of a hollow cuboid with transparent ends and a baffle is set in the middle of the chassis 1;

[0020] Ventilation systems are arranged above and below the baffle plate of the chassis (1). The lower ventilation system includes the first fan blade 51, the first motor 61 connected through the main shaft, and the first support column 71 supporting the first motor 61 to control the first motor 61. A PLC controller P of a motor 61, a power supply S for the PLC controller P, a first filter screen 81 is set at the air inlet of the lower ventilation system...

Abstract

A two-machine alternated work combined mining ventilation device comprises a machine case, wheels, a supporting plate, a first zigzag form bend ventilation pipeline, a second zigzag form bend ventilation pipeline, first fan blades, second fan blades, a first motor, a second motor, a first supporting column, a second supporting column, a first filter net, a third filter net, a second ejector column, a first ejector column, a second filter net and a fourth filter net. An upper ventilation system and a lower ventilation system are arranged in the machine case, and the supporting plate and the wheels matched with the supporting plate are arranged at the bottom of the machine case. Due to the fact that the two-machine alternated work combined mining ventilation device is provided with the two ventilation systems for alternated work, constant work of the integral ventilation device can be guaranteed through the manner. Due to the fact that the two-machine alternated work combined mining ventilation device is provided with a first zigzag form bend and a second zigzag form bend, air enters a non-working draught fan box through the zigzag form bends, accordingly, a working draught fan can be utilized for ventilation, and meanwhile the working draught fan can be used for cooling a non-working draught fan.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a two-machine alternately working combination type mine ventilation device.
