Description
Technical field
This utility model relates to coal mine safety ventilation device, a kind of iron automatic draught distributor.
Background technology
At present, at driving face in coal mine, when major-minor booster switches, air duct leaks out and maybe cannot switch,
Easily cause face gas to transfinite.Existing air devider has following defects that one is poor stability, and two is close
Envelope property is poor, and three is to be easily damaged.
Utility model content
The purpose of this utility model is the iron automatic draught distributor providing a kind of safety high.
The purpose of this utility model is achieved through the following channels: a kind of iron automatic draught distributor, it includes
Casing, casing one end is provided with main air blower air inlet, and the casing other end is provided with air outlet, and casing one side is provided with
Secondary air inlet, the cabinet wall between main air blower air inlet and secondary air inlet is provided with a rotating shaft,
Switching baffle plate is installed in rotating shaft.
As the further optimization of this programme, described switching baffle plate area is more than main air blower air inlet and secondary wind
The bore of machine air inlet.
As the further optimization of this programme, described main air blower air inlet and secondary air inlet and switching gear
Plate junction is provided with sealing joint strip.
As the further optimization of this programme, described main air blower air inlet, secondary air inlet and air outlet
Outside is provided with colloid air duct.
The iron automatic draught distributor of this utility model has the advantage that 1. automatizatioies.After connecting this device, only
Need to switch blower fan both can realize major-minor blower fan distinguished and admirable between switching.The most safer.Utilize iron welding,
Solid and reliable, and between switching baffle plate and cavity, sealing joint strip is installed, it is to avoid rigid contact, get rid of and produce
Pyrophoric probability, it is to avoid wind current control produces the probability of gas accident.3. technique is advanced.Whole dress
Put the pressure differential utilizing blast, by switching baffle plate, it is achieved the switching between major-minor blower fan is distinguished and admirable.
Its advantage is contrasted with existing device:
One, safety aspect.Utilize iron welding, solid and reliable, and pacify between switching baffle plate and cavity
Equipped with sealing joint strip, it is to avoid rigid contact, get rid of and produce pyrophoric probability, it is to avoid wind current control generation watt
The probability of this accident.
Two, closure is tighter.Traditional air devider, owing to using colloidal materials, easily causes and leaks out,
Reduce face air volume.This device is iron material, stable and reliable for performance, and switching baffle plate and cavity it
Between install sealing joint strip, it is to avoid pressure reduction produce leak out.
Three, easier for installation.Owing to being arranged above with, at switching baffle plate, the device that goes for a drive, it is simple to narrow in tunnel
In the case of narrow, secondary air inlet can be used to install downwards.And it has been arranged above with vertical and horizontal at cavity
Heave Here, it is simple under the conditions of different tunnels, takes different mounting means.
Four, switching is more flexible.Whole device utilizes the pressure differential of blast, by switching baffle plate, at major-minor
During PAU+FCU system, can realize major-minor blower fan distinguished and admirable between switching.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described in further detail:
Fig. 1 is this utility model structural representation；
In figure, 1, main air blower air inlet；2, secondary air inlet；3, air outlet；4, switching baffle plate；5、
Rotating shaft；6, sealing joint strip.
Detailed description of the invention
As it is shown in figure 1, the iron automatic draught distributor of this utility model, it includes that casing, casing one end are provided with master
Air inlet 1, the casing other end is provided with air outlet 3, and casing one side is provided with secondary air inlet 2, main
Cabinet wall between air inlet 1 and secondary air inlet 2 is provided with a rotating shaft 5, and rotating shaft 5 is installed
Switching baffle plate 4, switching baffle plate 4 area is had to be more than main air blower air inlet 1 and the bore of secondary air inlet 2,
Can realize between two air inlets automatically switch, after switching distinguished and admirable through cavity flow out air outlet.
Described main air blower air inlet 1 is provided with fluid sealant with secondary air inlet 2 with switching baffle plate 4 junction
Bar 6.
It is provided with colloid air duct outside described main air blower air inlet 1, secondary air inlet 2 and air outlet 3, main
Secondary booster and air inlet are connected by colloid air duct, and air outlet is connected by colloid air duct.
Described casing top is provided with horizontal and vertical installation suspension centre, it is simple to carry out different modes in different tunnels
Installation.
The iron automatic draught distributor of this utility model, utilizes differential pressure principle, in main air blower runs work process,
Pair air inlet is closed by the switching baffle plate within air devider, owing to secondary air inlet side is due to blast
Less than major-minor well one lateral pressure, thus when main air blower runs, baffle plate and sealing joint strip can stop main air blower
Distinguished and admirable spill from secondary blower fan.Otherwise, during secondary fan operation, switching baffle plate and sealing joint strip can stop secondary wind
Machine is distinguished and admirable to be spilt from main air blower.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is also
Be not limited to this, any those of ordinary skill in the art in the technical scope disclosed by this utility model,
The change can expected without creative work or replacement, all should contain protection domain of the present utility model it
In.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
