Below in conjunction with the drawings and specific embodiments, the invention will be further described:
A kind of low concentration short distance closed gas tapping equipment, as Fig. 1, shown in Fig. 2 and Fig. 3, comprise outer hush pipe 1, in outer hush pipe 1, be fixedly connected with interior hush pipe 12, between outer hush pipe 1 and interior hush pipe 12, be filled with silencing cotton 2, space in the middle of interior hush pipe 12 is silencers channel 3, the outer hanging ring 4 that is fixedly connected with of outer hush pipe 1, outer hush pipe 1 one end is fixedly connected with outer cooling pipe 8, the outer hanging ring 4 that is fixedly connected with of outer cooling pipe 8, the 8 interior airtight interior cooling pipes 6 that are connected with are managed in outer cooling, space in the middle of interior cooling pipe 6 is cooling passage 7, cooling passage 7 communicates with silencers channel 3 is airtight, the airtight air inlet valve 9 that is fixedly communicated with in cooling passage 7 outer ends, confined space between outer cooling pipe 8 and interior cooling pipe 6 is water cavity 5, airtight water intaking valve 10 and the outlet valve 11 of being communicated with on the tube wall of outer cooling pipe 8, and water intaking valve 10 and outlet valve 11 lay respectively at the two ends of outer cooling pipe 8.
Embodiment recited above is described the preferred embodiment of the present invention; not the spirit and scope of the present invention are limited; do not departing under the prerequisite of design concept of the present invention; various modification and improvement that in this area, common engineers and technicians make technical scheme of the present invention; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection, is all documented in claims.
The present invention is the device that a kind of airduct air feed aspect reduces noise, also can cry and fall 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 place that the present invention can install according to air line, the airtight point of short distance, small-sized chamber driving are not being used under the mode of local ventilation, use the blast of air line, utilize this device to realize the discharge 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 lowers the temperature two sections 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 by interior cooling pipe and outer cooling pipe two-layer composition, the interior cooling pipe of internal layer is 2 cun of steel pipes, outer field outer cooling pipe is 3 cun of steel pipes, and interlayer gap (being water cavity) locates to fill water, and water is lowered the temperature.Noise reduction section is also comprised of two-layer, and the interior hush pipe of internal layer is 2 cun of steel pipes, and outer field outer hush pipe is 4 cun of steel pipes, and crevice place is installed silencing cotton, is used for noise reduction.
When carrying out small-sized chamber driving, this device of hanging is in position installed, air line is connected with the air inlet valve of this device, open after air inlet valve, press wind to flow to noise reduction section through temperature descending section, then through outlet, needed wind place to carry out air feed.From temperature descending section, flowing to the process of noise reduction section, because the friction energy between blast and 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 fever phenomenon.
While pressing wind through this device air feed, can produce certain noise, the present invention has installed silencing cotton in the noise reduction section of this device for this reason, while pressing wind through noise reduction section, owing to being added with silencing cotton, has therefore reduced noise.Through the pressure wind in air port, after the cooling of this device, noise reduction, give again boring head air feed.This device is through to pressing after minute wind noise reduction of wind, offers that the effective wind rate of meeting head on is minimum can reach 0.27m/s, and noise is 78 decibels of left and right, meets the needs of safety of coal mines anger completely.
After using this device, can effectively improve workman's workload, greatly reduce the labour intensity that workman installs blower fan, enhance productivity.
