Embodiment recited above is described preferred embodiment of the present invention; be not that the spirit and scope of the present invention are limited; under the prerequisite that does not break away from design concept of the present invention; common engineers and technicians make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
The present invention is the device that a kind of airduct air feed aspect reduces noise, also can cry and fall the resistance air devider, is mainly used in the local ventilation of small-sized driving chamber, and noise is low, can ensure workers ' safety production.
The present invention can be according to the place of air line installation, the airtight point of short distance, small-sized chamber are tunneled under the mode of not using local ventilation, use the blast of air line, utilize this device to realize the discharging of short distance closed gas, guarantee the air feed safety of small-sized chamber driving, easy to install quick, saved labour cost.
The present invention comprises noise reduction and two sections of coolings according to the size of external diameter, the external diameter of temperature descending section is 3 cun, the external diameter of noise reduction section is 4 cun, temperature descending section is managed two-layer the composition by interior cooling pipe and outer cooling, the interior cooling pipe of internal layer is 2 cun steel pipes, outer field outer cooling pipe is 3 cun steel pipes, and interlayer slit (being water cavity) locates to fill water, and water is lowered the temperature.The noise reduction section also is made up of two-layer, and the interior hush pipe of internal layer is 2 cun steel pipes, and outer field outer hush pipe is 4 cun steel pipes, and crevice place is installed the noise reduction cotton, is used for noise reduction.
When carrying out small-sized chamber driving, in position install and hang this device, air line is connected with the air intake valve of this device, open the air intake valve after, press wind to flow to the noise reduction section through temperature descending section, then through exporting to carrying out air feed in the wind place.Flowing to from temperature descending section the process of noise reduction section, because the friction energy between blast and the interior cooling tube wall makes steel pipe produce certain temperature, the present invention is provided with a water intaking valve and an outlet valve at temperature descending section for this reason, utilize the mobile of water to cool, stop the generation of pipeline inner wall heating phenomenon.
Can produce certain noise when pressing wind through this device air feed, the present invention has installed the noise reduction cotton in the noise reduction section of this device for this reason, when pressing wind through the noise reduction section, owing to be added with the noise reduction cotton, has therefore reduced noise.Give the boring head air feed through the pressure wind in air port again after through the cooling of this device, noise reduction.This device is through to behind the branch wind noise reduction of pressing wind, offers that the effective wind rate of meeting head on is minimum can to reach 0.27m/s, and noise is about 78 decibels, meets the needs of safety of coal mines anger fully.
Can effectively improve workman's workload after using this device, greatly reduce the labour intensity that the workman installs blower fan, enhance productivity.
