Abstract
An automatic air compensating device of a tunnel relay fan comprises an inner cylinder, an outer cylinder, a conical cylinder, a support, an outer flange, an inner flange, a screw hole, mute cotton, fixed feet and compensation air inlets and is characterized in that the compensation air inlets are arranged on the inner cylinder and the outer cylinder, and each air compensation air inlet is composed of a frame, an air door and a filter screen; and each air door is composed of a plurality of blades with shafts on one sides, and the filter screens are fixed to the frames through screws. The automatic air compensating device has the beneficial effects that when the air sucking amount of the relay fan is insufficient, the air amount can be automatically compensated through the compensation air inlets, air cylinder cloth of an air hose is prevented from being sucked to be flat, the air hose is prevented from being damaged, and normal use of the relay fan is ensured.
Description
Technical field
The present invention relates to a kind of tunnel relay air blower, be 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
Object of the present invention overcomes the deficiencies in the prior art exactly, and provides a kind of tunnel relay air blower auto-compensation air quantity.
The technical solution used in the present invention 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 invention has the beneficial effects as follows: 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 invention will be further described.
Fig. 1 is the partial sectional view of embodiment of the present invention 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 embodiment of the present invention tunnel relay air blower auto-compensation air quantity, Fig. 2 is the left view of Fig. 1, embodiment of the present invention 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.
