Problems solved by technology

Because the distance between the parallel fans is too close, when the fans are running, the air flow passes through the machine station, and the local resistance of the fan station is relatively large, which increases the operating cost of the ventilation system

Embodiment 1

[0007] Example 1: A total of 3 sets of K40-6-19 fans need to be installed in the wind shaft-198m horizontal machine station, with a single unit capacity of 110KW. The original roadway space is fully utilized to make the fan station arranged in steps, and the 6 fans of the machine station are divided into Two groups, one of which is installed in parallel on the same section of the roadway 5, and the other group of fans are arranged in steps at a distance from it, and the roadway is sealed by the air wall 3 at the fan diffuser 2, and the wind wall between the two groups of fans is used to seal the roadway. The wall 3 is partitioned, and the damper 4 is installed, which is convenient for personnel to overhaul and maintain the fan. When the fan is running, the air flow passes through the machine station, which generates less local resistance, reduces the operating cost of the ventilation system, and at the same time reduces the roadway space for the machine station installation, sa...

Embodiment 2

[0008] Embodiment 2: The fan station is composed of 3 groups of fans, each group of fans is connected in parallel by 2 fans, each group of fans is installed in a staggered position, and is arranged in the roadway in a stepped manner.

Abstract

The present invention relates to an underground mine ventilation technology, specially relates to a step arranged anderground parallel fan station, and it is characterized by that an underground fan station is formed from the components of fan, brattice, ventilation door and underground roadway, according to the roadway space the fans of the fan station can be divided into several groups, the front group and the next group are alternatively separated at a certain distance, there fan groups are formed into the stepped form and arranged in the roadway, every group of fans can only have one fan,also can have several fans which are parallelly-connected and mounted on same section of the roadway, every two groups are partioned by brattice and equipped with ventilation door, and at the fan diffuser position said roadway can be closed by using brattice.

Description

(1) Technical field: [0001] The invention relates to an underground mine ventilation technology, in particular to an underground parallel fan station arranged in steps. (two), background technology: [0002] The underground fan station usually adopts the structure of multiple fans connected in parallel. The existing technical scheme is: the fan station is arranged on the same section of the roadway. This structural form requires a larger space. In order to meet this requirement, it is usually necessary to lift the roof and paint the roadway in the fan station section, which increases the engineering volume of the fan station. Such as figure 1 As shown, the machine station fan 6 is installed in parallel on the same section of the roadway 5, the roadway is sealed with the wind wall 3 at the fan diffuser 2, and the damper 4 is installed beside the fan, so that personnel can overhaul and maintain the fan. Because the distance between the parallel fans is too close, when the ...
