Abstract
The utility model provides a tunnel relay fan automatic compensation amount of wind device, includes interior barrel, outer barrel, conical shell, support, outward flange, inner flange, screw, cotton, the fixed foot of amortization, compensation air intake, its characterized in that: including be provided with the compensation air intake on barrel and the outer barrel, the compensation air intake by frame, air door, cross filter component, the air door is by the blades of multi -disc one side tape spool, the filter screen by the fix with screw on the frame, the beneficial effects are that: the relay fan is when induced drafting the quantity not sufficient, and the accessible compensates the air intake automatic compensation amount of wind, prevents to inhale the dryer cloth of flat tuber pipe, avoids the tuber pipe to damage, guarantees the normal use of relay fan.
Description
Technical field
The utility model relates to a kind of tunnel relay air blower, is specifically related to a kind of tunnel relay air blower auto-compensation air quantity.
Background technique
Execute man-hour requirement at a distance at long tunnel and increase relay air blower on airduct, relay air blower, when suction air volume is not enough, can inhale the air duct fabric of flat air dust, damages airduct, causes relay air blower normally not use.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art exactly, and provides a kind of tunnel relay air blower auto-compensation air quantity.
The technical solution adopted in the utility model is to achieve these goals: a kind of tunnel relay air blower auto-compensation air quantity, comprise inner barrel, outer cylinder body, conical shell, support, outward flange, inner flange, screw, silencing cotton, fastening foot, compensation intake grill, it is characterized in that: on inner barrel and outer cylinder body, be provided with compensation intake grill, compensate intake grill to be made up of framework, air door, filter screen, air door is made up of the blade of multi-disc one side tape spool, and filter screen is fixed on framework by screw.
Compared with prior art, the beneficial effects of the utility model are: relay air blower, when suction air volume is not enough, by compensating intake grill auto-compensation air quantity, prevents the air duct fabric inhaling flat air dust, avoiding airduct to damage, ensureing the normal use of relay air blower.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the partial sectional view of the utility model embodiment tunnel relay air blower auto-compensation air quantity;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the view of blade 13 when opening.
Icon illustrates: 1. inner barrel; 2. outer cylinder body; 3. conical shell; 4. support; 5. outward flange; 6. inner flange; 7. screw; 8. silencing cotton; 9. fastening foot; 10. framework; 11. air doors; 12, filter screen; 13, blade; 14, screw.
Embodiment
Fig. 1 is the partial sectional view of the utility model embodiment tunnel relay air blower auto-compensation air quantity, Fig. 2 is the left view of Fig. 1, the utility model embodiment tunnel relay air blower auto-compensation air quantity, on the baffler of relay air blower air sucking mouth, set up compensation intake grill, the baffler of relay air blower air sucking mouth comprises inner barrel 1, outer cylinder body 2, conical shell 3, support 4, outward flange 5, inner flange 6, screw 7, silencing cotton 8, fastening foot 9, inner barrel and outer cylinder body are provided with compensation intake grill, compensate intake grill by framework 10, air door 11, filter screen 12 forms, air door 11 is made up of the blade 13 of multi-disc one side tape spool, when suction air volume deficiency compensates air intake, blade 13 can be opened automatically, Fig. 3 is the view of blade 13 when opening, when blast more very much not needs to compensate air quantity at ordinary times, blade 13 is in closed condition, with anti-gas-leak, filter screen 12 is fixed on framework 10 by screw 14, can take off and clean.
Such relay air blower when suction air volume is not enough, by compensating intake grill auto-compensation air quantity, can the foreign material such as remove portion flue dust after filter screen 12 filters, guarantee air intake cleans, ensure the normal use of relay air blower, this device can prevent the air duct fabric inhaling flat air dust, avoids airduct to damage.
